Why do you charge the phone, it is discharged. Phone is draining while charging
If the phone began to discharge quickly, this does not mean that the battery is to blame. In 70% of cases, the user himself configured the device in such a way that it consumes a lot of battery power. Of course, the battery may also be to blame, but first you should try changing the settings, as well as calibrating the device’s battery.
What to do if the smartphone is quickly discharged
There are many reasons why the battery is discharged in a matter of hours. Now we will consider the most basic of them and see how they are eliminated.
Reason 1: Maximum brightness
Often, users do not hesitate to set the display brightness of their device to high. However, keep in mind that the larger it is, the higher the battery consumption of the screen. The acceptable brightness level is 40-50%. In the latest version of Android, you can adjust the brightness from the curtain.
Reason 2: Many wireless modules are activated
If the battery on the phone began to discharge quickly, you may have turned on the mobile Internet, bluetooth, Wi-Fi and do not turn it off. These modules are capable of draining the battery charge in a short period of time. You can turn them off via the menu. "Settings" your device or through the curtain, which is pulled out with a finger from the top of the display.
Reason 3: Applications running in the background
Sometimes the culprit for why the Android phone quickly began to discharge is applications that work in the background and consume power. To find out what programs are running in the background:
- Open menu "Settings".
- Get down to the block "Device" and tap on the section "Applications".
- There, you need to swipe your finger to the right until you find yourself in the section "Working".
- Under the caption: "RAM Usage" will be all currently running programs. You need to click your finger on unnecessary ones and press "Stop".
After that, applications will stop their activities in the background, and the battery in standby mode will drain more slowly.
Reason 4: Incorrect charge display
Incorrect calibration is a common reason why a new phone runs out of battery quickly. You need to calibrate the battery of your device, and for this:
- Discharge the battery completely to turn off the device.
- Then take out the battery for 10 minutes and put it back in.
- Put the smartphone to charge for 8 hours (this is important).
- After this a period of time you need to remove the smartphone from charging.
- Then you need to remove the battery and wait 10 minutes to insert it back.
- You can start the device, the battery is calibrated.
Reason 5: The power controller is out of order
Rarely, but still, the power controller can break down and send incorrect readings to the system, thereby not all the charge will be used and the battery will slowly charge. What to do? In this case, you need to carry the smartphone to a service center for repair or replacement of the chip.
Reason 6: Update and Firmware
Often, it is after updating the device that the battery starts to discharge quickly. Developers make a mistake. In this case, you should roll back, if possible. Even unofficial firmware can also be poorly optimized and consume a lot of charge. Therefore, it is always better to use only stock firmware.
Reason 7: Viruses
Malicious applications are one of the reasons why the battery runs out, as they run in the background and constantly consume battery. To scan your phone for threats, you need to:
- Go to Google Play Store.
- Enter in the search bar Dr. Web and install the proposed application on your device.
- Run it and check your device for threats.
Over time, the battery begins to deteriorate, hold a charge less and heat up. If you use it for about 3 years, it is worth replacing the battery with a new one.
Reason 9: Imbalance
Some devices from Samsung encountered such a problem when the battery capacity was not enough for the installed hardware. In this case, you should use portable batteries - Power Bank.
- On the Internet, you can often find advice to use battery calibration applications, such as Battery Calibration. In fact, it is absolutely useless. Some claim that it helped, but these are isolated cases, and most likely the reason was not even that.
- There is also a recommendation to use the Clean Master application to clean the device and optimize. This makes no sense, since all these programs consume a lot of charge and load the device. They are suitable if you need to clear the device's memory, after which it is recommended to delete them.
Conclusion
That's all. Now you know why the battery on the phone began to discharge quickly. Of course, you can find a number of other reasons, but I have highlighted the most basic of them. Use the recommendations I have given and do not see dubious advice on the Internet.
Many users have a problem phone is draining while charging, even when acquired, quite recently. The question immediately arises, what to do and how to fix it.
- Phone and software settings.
- Phone overheating.
- Conclusion.
Bought a phone but use a universal charger.
When charging with a universal device, not native, one must be guided by the output current strength, all phones have a calculated and certain charge power. If the nominal values of the charger are more than provided for on the phone, then this will simply lead to the inevitable breakdown of the device. Or using a less powerful charger, the phone will not charge or it will take a long time to charge. Usually this happens, who charges from a PC.
The cable is defective or damaged.
It can also be the reason that the phone is being discharged while charging, cable damage, visually you may not even notice it, but the charge periodically disappears or it does not exist at all. To do this, you need to feel the entire cable along its length, with little effort, as if stretching it, and if the cable is broken inside the insulation, then you will feel a slight thinning of the cable. With a stronger stretch in this place, it will simply tear. In this case, you need to twist the cable and insulate it or contact any repair service.
Broken phone charger.
This is common among many phone users. This is due to the incorrect insertion of the mini USB cable into the phone connector (upside down). It also happens from sharp jerks of the phone or the cable itself when charging. For example, your phone is charging, and you accidentally hit it with your foot or hand, caught on the wire and jerked the connector out of the socket. You can also break the socket into a kink when charging. This happens when your gadget is charging and you use it, for example, while playing games. You are so passionate about your actions that you don’t even notice how a break occurs at the connection point in one direction, then in the other, and this will inevitably lead to a breakdown of your power socket. In this case, one cannot do without service center, since all elements of the phone are soldered by automatic robots, you will not be able to fix the problem yourself.
How to determine that you have a faulty socket in the phone. You will need to remove the battery from the phone. Connect the battery directly to the device being charged, the so-called "Frog" by the people. If the battery is charging, then the conclusion is simple, the socket in the phone is not working properly. But do not forget that the battery has a positive and negative terminal, strictly observe the polarity of the connection. As well as safety rules when working with electricity.

Phone and software setup.
After checking all the points indicated above, and not finding a single cause of the malfunction. Use only Charger the corresponding denomination that came with the kit. Then you should pay attention to the software of your device. You will need to go to your phone settings and make sure you have latest version software. Usually, when buying a new phone, there is outdated software, in this case, go to the system update section and run "check for updates", the phone will automatically check the network for updates and install the updated version if necessary. But remember that when you start the update, you will need to make sure that your phone is fully charged. during the download, you will not be able to interrupt the installation, otherwise there will be software failures and the firmware of your smartphone will be required. The updated software will monitor your device and monitor basic functions such as screen brightness and speaker volume. If necessary, you can independently reduce the brightness of the screen and the volume of the speaker.
Additional work programs.
By installing these or other additional programs, you also increase battery consumption. Some of them may work in background, you won't even know that they are on and are constantly scanning your system or the Internet. Naturally, they will not only slow down your phone, but also significantly increase battery consumption. You can find them in the "power" or "battery" section, it displays in percentage terms all programs consuming energy and, if necessary, disable them in the "all applications" section. Or by downloading the necessary program in the "Play Market" (Internet).
Phone overheating.
The phone usually gets warm while charging. And if you are still using the device at this moment, then you are provided with overheating. It is recommended to turn off the phone, let it cool down after prolonged use, and only then turn on the charger. Failure to follow these rules will result in overheating and your device will fail. It is also possible to ignite.
Conclusion.
Before use, carefully read the operating instructions, and strictly follow all the recommendations prescribed in the instructions. Only then can you count on the correct operation and durability of your device.
Phone is draining while charging
Average rating 5 (100%) Voted 2 votes
The problem of too fast discharge of the battery (battery) is faced by almost all users of mobile gadgets. The problem occurs gradually and goes unnoticed for some time, but one day the owner notices that the time battery life smartphone or tablet has almost halved. If you do nothing, it will decrease further - until it becomes impossible to use the device. And one day the device will not turn on at all.
Let's talk about why the battery on Android devices runs out quickly and how to extend its life.
Reasons for fast battery drain
- The actual battery capacity of the smartphone or tablet is lower than specified in the specifications.
- Battery capacity has decreased due to normal wear and tear.
- The ambient temperature is below +5 ⁰C or above +30 ⁰C.
- Screen brightness set too high.
- Resource-intensive features included: GPS, NFC, Bluetooth, etc.
- Long distance to the base station of the mobile operator.
- Power is consumed by apps and widgets running in the background.
- Frequent switching on and off of the device.
- Mobile virus infection.
- A malfunction of the operating system or hardware, as a result of which individual resource-intensive functions or the device itself are not turned off.
Battery capacity is lower than in the passport
The discrepancy between the actual battery capacity and the indicator indicated in the passport of a smartphone or tablet is more common than you think. It's just that very few users dare to double-check it. Most people trust documents, as well as program indicators, which also do not always display reliable data.
The reason for the discrepancy between the actual information and the nominal one does not always lie in the deception on the part of the manufacturer or seller (although this also occurs), it is just that lithium power supplies lose their capacity during long-term storage. If you bought a device released a year ago, even with proper storage, its battery has become less capacious by 2-6%, and with incorrect storage (that is, with a charge of up to 100%), by as much as 15-30%.
To calculate the actual capacity of the battery, chargers and dischargers, like iMAX, or home-made arresters complete with a multimeter or USB tester are used. Accurate indicators are determined during the discharge of a fully charged battery.
If the battery capacity of your phone turned out to be less than the declared one, then it will be discharged in more than a short time than expected. And, alas, it is impossible to influence this.
Capacity decreased over time
Battery wear becomes noticeable after 1.5-2 years of using a smartphone or tablet. But it can come earlier if:
- often and for a long time use the device at low and very high air temperatures (the most favorable for the operation of lithium batteries is room temperature);
- allow a discharge close to 0%.
- charge the device near heat sources;
- store an unused battery at 100% charge at high temperature environment(for storage, the optimal charge level is 40-50% and the temperature of the refrigerator);
- charge the battery with a higher voltage and current than the manufacturer provided (the required level of current and voltage is indicated on the charger that was sold with the gadget).
Frequent short-term recharging, contrary to popular belief, does not harm the battery. A much greater influence is exerted by the current with which it is charged. Lithium batteries are preferable to charge with low currents, although this takes longer.
If the battery capacity of your device has decreased due to wear and tear, the only solution is to replace the battery with a new one.
Using the gadget in the cold or heat
When using a mobile device in adverse temperature conditions (up to +5 ⁰C and above +30 ⁰C), the battery discharges much faster, but at a temperature close to room temperature, its capacity is immediately restored to its original level.
If you do not do this too often, the battery will not wear out soon, but for calls in the cold it is still better to use a headset and keep the phone in a warm pocket.
High screen brightness
The screen of a mobile device on Android is the main consumer of energy. The brighter it is illuminated, the faster the battery drains.
The use of adaptive backlighting, which changes depending on the ambient light, helps to reduce battery consumption (only available on devices equipped with a light sensor). To turn it on, check the "Auto" box in the screen brightness settings. And so that the screen does not remain on when you are not using the gadget, set it to go to sleep after 30-60 seconds of inactivity.
Resource intensive features
The following active energy consumers after the screen are:
- geolocation;
- live (animated) wallpapers;
- NFC and Bluetooth;
- mobile Internet (3G, 4G).
- WiFi.
If they are all used at the same time, even the most capacious battery will run out very quickly, so if possible, turn off what you do not use.
Unstable cellular connection
You may have noticed that when you stay for a long time in places where the phone does not pick up the signal of the operator's base station, for example, outside the city, the battery is discharged faster than usual. This is because it takes more energy to maintain an unstable, dropping connection.
The battery will drain faster even if the problem is only with one of the two SIM cards. To save the charge, it is better to turn off such a SIM card for a while.
Apps and widgets running in the background
Many Android applications and widgets, after installation, prescribe themselves to autorun and work in the background all the time while the device is turned on. When there are a lot of such applications, the device not only discharges very quickly, but also noticeably slows down, so autoloading should be kept under control and allowed only for those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).
Unfortunately, there is no autorun control function for user and system applications in Android. But it becomes available after obtaining root (superuser) rights and installing special utilities on the device, such as:
- BootManager and some others
There are utilities that allow you to manage autoload without root rights, but they do not work on every gadget and not always correctly.
Applications that the user himself launched, but after they were no longer needed, he forgot to close, can also consume battery resources. The accumulation of such programs not only loads, but also heats up the processor, and from it, in turn, the battery heats up. And when heated, as we know, the phone's battery runs down very quickly.
Control over processes that actively consume energy is also best entrusted to special utilities. For example, the following:
- Clean Master, etc.
By the way, the capabilities of most of them include cleaning the system from junk files, CPU cooling, charging optimization and a number of other tasks. To keep the device in order, it is advisable to use one of these utilities constantly.
Frequent reboots and turning on/off the device
Wanting to conserve battery power, some users regularly turn off their mobile gadget. Sometimes even several times a day. This is another reason why the battery drains too quickly, since when the device is started and the operating system is loaded, the energy consumption is close to the maximum.
While you are not using an Android smartphone or tablet, you should not turn it off completely - just turn off the screen, complete resource-intensive tasks, disable communication functions (Wi-Fi, GPRS, 3G-4G Internet, GPS, NFC and Bluetooth), background data transfer, sensors and vibration motor. To do this, most mobile gadgets have a power saving mode, the power button of which can be located in different sections of the settings (parameters) menu.
Mobile virus infection
Malware that attacks Android devices does not always operate openly. Often they carry out activities that are invisible to the user, and the only signs of their presence are empty accounts and very fast battery discharge, including in standby mode.
Hidden virus infection should be excluded for any non-standard behavior of the gadget, for example:
- The phone or tablet wakes up without any action from you.
- The device is warm when it is in sleep mode.
- Wi-Fi, geolocation, mobile Internet and other modules are enabled on the device without your participation. Or they can't be turned off.
- Unknown numbers appeared in the list of outgoing calls and SMS, and views of sites that you did not visit appeared in the browser history.
- An application has appointed itself as a device administrator without your knowledge.
- Stopped running for unknown reasons Google Play antivirus and other security applications.
- Some system functions have stopped working.
- The volume of network traffic of the device has increased for no reason.

System or hardware failure
Some PC and laptop users have encountered such a problem as incomplete shutdown of the computer, when the screen goes blank when the operating system is shut down, but some of the devices remain active - the cooler continues to rotate, indicators are lit, etc. The exact same problem occurs on mobile devices, it's just not so easy to notice, because there is no cooler on smartphones and tablets, and the indicator only shows the charging stage. With such malfunctions, the device essentially remains on all the time and, accordingly, even in the “as if off” state actively consumes battery power.
The causes of such problems can be crashing applications, viruses, operating system errors and a malfunction in the hardware of the device (including connected devices - memory cards, SIM cards, etc.).
The only symptom that allows you to suspect an incomplete shutdown of the device is too much battery consumption at a time when it should be minimal. And to make sure if this is really your case, just remove the phone (tablet) cover and check the processor temperature with your fingers. If the device continues to work after turning it off, its processor will remain warm. Sometimes in this state, the case of the device heats up slightly, but sometimes it does not - it depends on its design.
What in such cases can the user do without contacting the wizards:
- Remove applications installed before the problem appeared (if you managed to fix the time it started).
- Run an antivirus scan.
- Disconnect all connected devices.
- Reset the system to factory settings.
- Remove the battery (if it is removable), hold down the power button for 20-30 seconds and replace the battery.
- Flash the device with a known working firmware.
After each manipulation, check the gadget by turning it off. If the problem persists, you will have to take it to a service for repair, since the malfunction will not disappear on its own, and the battery will run out of its resource much faster than during normal operation.
Many of us have found ourselves in situations where the phone is about to run out of power in the middle of the day, the smartphone shows only 10 percent of charge and flashes red menacingly, and there is no charger at hand. And at the same time we are located in the city center, there are no friends nearby who would lend a charger. What can be done in such a case?
We will not give such obvious advice as to always carry a charger with you or a portable charger that does not require an outlet. Moreover, in megacities, every second owner of a smartphone always has a charger with him. But it also happens that we can simply forget to take this vital thing with us, accidentally leaving it in another bag or on the bedside table. Therefore, let's try to decide what to do if neither a charger nor a portable charger is in your arsenal.
We can offer you some simple and effective ways to charge your phone when you don't have a charger. Namely, we will tell you about places where you will be helped to solve this problem.
1. If you are in or near a mall, look for a store that has charging lockers. Usually in some stores of well-known networks there are small cabinets with chargers for various connectors. And while you try on clothes - your phone will charge.
A similar service is available, for example, in the Moskva bookstore on Tverskaya Street. Ask the information department to charge your phone - you are unlikely to be refused.
2. Another easy way is to go to any mobile phone store and ask to recharge your phone. The chances of you being rejected are very small. But it is best in such cases to contact the salon of one of the operators - in some such services are taken for granted. In addition, mobile phone stores have chargers for all models. You can also go to the electronics store with the same request.
Whether this service will be paid depends on the seller. However, if you have to pay, then a little - 50-100 rubles maximum.
3. There are special terminals for charging phones. Unfortunately, there are not as many of them as ATMs and payment terminals. They are usually found in large shopping malls, in cafes, waiting rooms at railway stations and airports. There are several wires in the terminal cells that are suitable for all smartphones. This pleasure costs about 50 rubles per hour.
4. Smartphones are known for running out of battery faster than regular phones. This happens for various reasons. We want to tell you about a few more life hacks that will speed up the charging process and save energy on your smartphones.
If you have very little time to recharge, then turn on airplane mode on your smartphone - and charging will go much faster. You can also just turn off your phone while charging. The smartphone will not consume energy, but will receive it much faster.
5. If you can’t turn off your phone or put it on airplane mode, because you don’t want to miss an important call, then try disabling unnecessary features. It can be GPS, Bluetooth, Internet connection. All these functions take part of the energy. By disabling them, you can speed up the charging process a bit. Keep these features turned off when using your smartphone if you are not using them directly. So your smartphone will be discharged more slowly. There is also a classic useful advice to save energy - reduce the screen brightness and screen auto-off time in the settings.
Tablet computers actively fill the life of a modern person. They delight with bright colors of the screen, smooth lines of forms, many useful functions, solving problems, helping and entertaining their owners. But sometimes one problem somewhat overshadows communication with an electronic friend - the tablet's battery runs out quickly. It is especially unpleasant if an alarm signal that the device needs charging catches the owner of the tablet in transport, a store or other public place, in general, far from a power source.
It is clear that the problems of quickly discharging the tablet battery cannot be solved in the ways that help. Here you need completely different activities and knowledge.
The reasons why the tablet battery runs out quickly can be hidden, on the one hand, in the type of battery used, its charging modes, storage and operating conditions, on the other hand, in the intensity of using the tablet and the nature of its functions.
Modern tablet computers run on lithium-ion (Li-ion) or lithium polymer (Li-pol) batteries. Unlike older Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries, Lithium Ion and Lithium Polymer batteries do not suffer from the memory effect and therefore are less demanding on the charging regime. They do not have to be completely discharged before the next charge. Nickel-cadmium and nickel-metal hydride batteries, on the other hand, lose capacity if they are not fully discharged before the next charge cycle (memory effect). Obviously, when choosing a tablet, it is better to focus on the option that has a lithium-ion or lithium-polymer battery. A lithium-polymer battery is almost 2 times thinner and lighter than a lithium-ion one (with the same capacity), but at the same time more fragile and much more sensitive to drops, bumps, etc. stress.
When buying a tablet equipped with a lithium battery (Li-ion or Li-pol), or a separate lithium battery, you need to pay attention to the date of manufacture of the device, as the battery loses about 20% of its capacity per year even when not in use. If the device has been in the warehouse for about 2 years, it is better to refrain from buying.
Many owners of smartphones from Samsung and other popular brands are familiar with one problem - the battery on Android runs out quickly. The full energy reserve goes to zero in 13-14 hours even of inactive use. A similar problem occurs with tablet owners on this operating system.
Why is my phone draining fast
- Turn off 4G LTE if you don't have coverage in the city.
- Turn off mobile internet if you are not using it.
- Often WI-FI is enabled on the phone by default. This is a very serious consumer of power, so it should be deactivated if it is not in demand. The module regularly connects to the Google Play service to download app updates and then installs them in the background.
- bluetooth. A technology that is now rarely used, but it consumes the battery.
Check the charger
Try leaving your device on charge for an extended period of time.
Try turning the charger on and off and at the same time trying to turn on the tablet
To find out exactly whether this is the reason, a battery test using special equipment will help. If the fears are confirmed, then you need to change the battery to a new one. It is important to use original accessories. Spare parts are not from the official representative and Chinese copies will be able to solve the problem only for a certain period.
Also, a problem can occur with the power adapter. The tablet may indicate a full charge, but in fact not be even half charged. Because of this, the operating time is very short. It is extremely difficult to solve such a malfunction, specialists can replace the microcircuit, but this will be expensive and does not guarantee a positive result.
Means of communication
As you know, data transfer puts a high load on the battery of the device. Therefore, so that there is no fast discharge, you need to turn off:
For this:
- in the settings you need to go to the "communications" menu;
- click the icon on one of them to turn it off/on.
Backlight
Another cause of battery drain can be the screen backlight. It is this function that consumes about 57% of the charge in any technique. If possible, you need to set the minimum or average backlight level. Many tablets have sensors that change the light level automatically. If ambient lighting does not need to change the screen settings, then this function should be disabled, because it also adds load.
There are also times when the tablet is idle, and the display glows. Therefore, you need to set the automatic blocking. This will not interfere with video games and browsing the Internet, and when reading books, this feature can be turned off.
Adjusting the screen backlight is one of the easiest battery-saving options. It does not require special knowledge and tools, but it helps to solve such difficulties.
To change the brightness level and auto-lock time, you need to:
- in the settings, find the "screen settings" menu;
- adjust the settings by selecting the minimum or average values.

OS setup
Modern tablets have gone far from the first portable computers and smartphones on which you could start your favorite online chat, watch a video and kill time with games. Now gadgets practically live their own lives, making independent trips to the Internet, bringing newer versions of programs from there.
Main actionssystems, which plant a charge, can be considered:
- automatic data synchronization;
- periodic polling of the network;
- software update.
Automatic data synchronization
- video games;
- media players;
- social media clients;
- communication applications (Skype, Viber, etc.);
- browsers;
- area maps;
- file exchangers;
The developers of such applications are constantly trying to improve them, so they make changes. Signals are also sent by remote servers. The tablet joyfully shakes all these new things even without the permission of the owner.
Particularly different are devices on Windows OS. They constantly check all programs for updates. This increases the load on the device and its battery. Therefore, you need to turn off automatic updates and follow the updates yourself. Disabling all unnecessary actions of the operating system is quite simple.
For this you need:
- go to settings;
- uncheck the box next to the items that you want to turn off;
Apps running in the background
An advantage and at the same time a disadvantage of modern gadgets can be considered the ability to work several programs together. Of course, you can also run the music player and browser at the same time, chatting with friends on social networks and listening to the latest music.
The disadvantage of this feature is that when you start the second application, the first one continues to work in the background and wastes RAM. This is where the multitasking feature comes in. At the same time, background applications do not always bring benefits, but often simply exhaust the resources of the device.
Only with the accumulation of a large number of running applications, the system closes on its own, those that have been on for a long time.
The most popular programs that sit in the background are:
- media players;
- reading rooms;
- video games;
- file managers;
- various settings.
The developers offer a variety of "tax killers" that will independently close the unnecessary, but, as practice shows, such utilities only reduce the gadget's operating time. It is better to monitor gluttonous software on your own. You also need to remove those applications that are rarely used, but appear in the background from time to time.
He divides programs into three points:
- loaded;
- performed;
Using the "Stop" button, you can remove unnecessary processes. At the same time, it will not harm the operation of the gadget; it is impossible to disable the necessary programs.
On theiOSto close background programs:
- double-click the Home button to open the task manager;
- stop unnecessary processes.
On OSWindows:
- to launch the task manager, you need to swipe the sensor from the left side of the screen to the center and back, while not lifting your finger;
- stop applications.

Additional effects
Recently, animated wallpapers have gained popularity. Depending on the position of the device, the pattern changes. There are all sorts of options for such effects, this is falling snow, and a “live” waterfall, and even a car that constantly travels around the display.
It is clear that these reduce the operating time, because they simultaneously load the processor, gyroscope and accelerometer chips. And you can easily do without such wallpapers, because simple images perfectly perform this function.
One of the latest know-how in the field of improving the design of a working device is 3D wallpaper. This, of course, looks nice, but reduces battery life, so it's better to change the screensaver to a regular picture or photo.
For this:
- in the gallery you need to select an image;
- click on the "set as wallpaper" button.
Tablet drains quickly
The fact that the device is discharged very quickly due to powerful games, a bright display, etc. - This is clear. But, there are situations when the gadget loses its charge, even if no one touches it.
In standby
When the tablet just stands idle, the charge still disappears. Sometimes up to 50% of the battery sits down in one night. The problem is that even without an owner, the gadget is actively looking for new software. Therefore, many programs just need to be disabled.
Of course, such a loss of charging is immediately noticeable. But still, it is worth studying the power consumption of the gadget in different modes of operation. This should be written in the instructions for the technique and checked using special programs. Battery wear may also be the cause.
If she was often completely discharged, or drew excess energy from a powerful outlet, then her performance characteristics are falling. You can solve this problem only by buying a new original battery.
Off
The battery percentage may drop even when the gadget is turned off.
This happens due to several factors:
- not completely off state;
- WiFi;
- operating system;
- technical difficulites.
People quite often, instead of turning off the technique, simply turn on the sleep mode. In this case, of course, it spends less energy than when it is on, but it still spends. To solve such a problem is very simple, to turn off the gadget, you need to hold the button for 5-10 seconds.
The second reason for discharge can be a functioning Wi-Fi. Equipment manufacturers claim that Wi-Fi is not terrible for turned off gadgets and does not affect their charge level in any way. But, many tablet owners confirm the opposite. A variety of programs that feed on the resources of turned off equipment can also damage.
The most unpleasant reason for the loss of charge can be the breakdown of some parts. This could be battery wear, which was mentioned earlier, and even damage to the motherboard. In these cases, only the repair or replacement of components will help. If the technical condition of the gadget is satisfactory, then it is very easy to solve the problem of discharge by following the above tips. Then the equipment will please with reliable and high-quality functionality.
