Tablets today, despite the increase in the size of smartphones, have not lost their relevance at all - functionally they are superior to smartphones in everything. Moreover, they are still at the peak of popularity among people who spend a lot of time on the road. You can do literally everything you can do on a smartphone, and even more.
Reading books, listening to music, comfortable watching movies and convenient control of games for large displays are not the full range of tablet capabilities. And if you connect an external keyboard to it, you can also conveniently type large amounts of text, as well as comfortably communicate on social networks. The only drawback is that you need to somehow recharge this device on the road.
Can I charge my tablet while working?
In theory, nothing interferes with using the tablet while charging. However, in practice everything is not so simple. If you use a device connected to a power supply, at least two problems can occur. The first problem is that you can damage the charging connector or connector on the tablet. The second problem is that the battery will reach a state of reduced maximum energy capacity much faster due to long recharge cycles.
Useful tips
Listed above are the most common reasons why the battery on your tablet drains quickly. There are a number of useful tips that will help improve its autonomy.
Limiting resource-intensive applications
Fast discharge is not always the case - this is a consequence of the work of numerous applications; sometimes the turned on antivirus or launching a game is enough for this. In the first case, it is recommended to turn it off during the period when the user is not using the Internet, because the network is the main source of viruses, and if you just watch a movie from a flash drive, it will be very difficult to pick up anything. When it comes to games, you need to know when to stop, because they not only lead to rapid discharge, but also generally depress the battery. It is especially painful for a tablet computer to play while charging. At the same time, the device gets very hot, which affects the battery life.
Important! Another serious source of battery consumption is the vibration response of the sensor and vibration when calling. If they are not particularly necessary, then any vibration should be turned off in the settings.
Many manufacturers, in their native settings, offer customers the use of live wallpapers, that is, animated images. It should be understood that they and economical battery consumption are concepts that are far from each other.
Control background processes
The Android system is very smart, and one of its features is automatic application synchronization. This happens in the background when the device is in standby mode. It happens that the user left the tablet overnight without a power connection, and in the morning discovered that it was discharged. In this case, it is recommended to look into the application settings and disable synchronization where it is not needed, and in addition, you should not leave the device connected to wireless networks at night if the device is not charging at the same time.
Selecting a power adapter
Sometimes the reason that the tablet does not hold a charge is the connected power supply. If it is too powerful for the gadget, then the device charges quickly, but also drains quickly. The other side of the coin is that the block is too weak. In this case, the device, on the contrary, charges slowly and the battery may not gain a full charge. Using an incorrect adapter may result in the gadget not charging at all.
Advice! The optimal solution is to use the included charger, or purchase a third-party accessory, but with similar power and current parameters.
Device storage
A useful tip that may seem counterintuitive is that you should not store the device in a switched off state. As practice shows, a gadget in sleep mode will lose less charge in the same period of time than one completely turned off. It happens that a user bought a new tablet, but simply turned off the old one and hid it in a box. After a while, you may find that the battery has become unusable. The best solution is to charge it periodically or remove the battery altogether, if this is provided for by the design of the device.
Important! To prevent the battery from draining quickly, it is not recommended to leave the device near heat sources or in the sun. This has a detrimental effect on the battery capacity.
Rules for using batteries
Several years ago, there was a theory that for a battery to work properly, it is necessary to charge it several times immediately after purchase and completely discharge it, since the battery has a memory effect. The second interesting myth is that it is recommended to charge the battery to 100%. Asus has refuted these theses and, as recommendations for its technology, indicates that it is optimal to keep the battery between 20 and 90% capacity . That is, you should not bring the gadget to zero state, and you should also not charge it to 100%.
Today you can notice that equipment from some manufacturers (including Asus), when charging 90%, changes the color of the LED, which symbolizes a full charge, and sometimes forcibly stops further charging, although the device still remains connected to the power supply. This is done to show the owner that the gadget is ready for use, and further charging will have a negative effect.
How to find out the number of charging cycles?
To find out how many cycles have passed since the battery was first recharged, just install the Battery Life application or similar ones. They display information from the tablet’s engineering menu and also carry out full diagnostics. Among other things, the battery status will be indicated based on all data, the current charge level, the maximum allowable charge level and the number of complete charge-discharge cycles.
Screen brightness
Today, the most energy-efficient display matrices are AMOLED from Samsung. They are found in devices in the expensive segment. More affordable devices use TFT or IPS matrices, which seriously consume energy. You can read more about the types of matrices in this material.
If the battery on your tablet is quickly discharged, you should abandon the maximum display brightness and reduce this parameter to 30-35%. This is enough for comfortable use.
In addition, any device on the Android OS has an automatic brightness adjustment mode and, as practice shows, in modern models from famous manufacturers it works correctly. Using a light sensor, the gadget itself understands the conditions of use and makes the screen darker or, conversely, brighter.

Selecting a tablet battery to replace a faulty one is not as difficult as it seems. To do this, you need to find out the tablet model or the factory code (part number) of the battery. This will significantly increase the likelihood of finding an original battery to replace the old one.
If it is not possible to purchase a “original” battery, then you can choose an analogue one. But you need to choose it from a reliable manufacturer, not paying attention to noname analogues. In order not to make a mistake and take a high-quality battery for replacement, it is best to visit large online stores with spare parts. At Parts Plus, for example, high-quality alternatives to branded batteries are presented in a wide range.
Causes and solutions
The cause of this problem can be various factors, each of which has its own characteristics of elimination.
Technical problems
The likelihood of such malfunctions is very low, but it also happens that the power supply system is in poor condition. The device's battery has its own service life, which includes a certain number of charging cycles. After this period, the part fails or begins to work very poorly. Such troubles can occur due to the use of power adapters that are not suitable for a particular device. In such cases, the equipment is overloaded and its temperature rises. Such problems occur very rarely, but, nevertheless, can cause a rapid discharge.

A battery test using special equipment will help you find out exactly whether this is the reason. If your fears are confirmed, then you need to replace the battery with a new one. It is important to use original components. Spare parts not from an official representative and Chinese copies will be able to solve the problem only for a certain period.
Problems can also occur with the power adapter. The tablet may indicate that it is fully charged, but in fact may not be even half charged. Because of this, the operating time is very short. Solving such a malfunction is extremely difficult; 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 device's battery. Therefore, to avoid rapid discharge, you need to turn off:
- Bluetooth;
- Wi-Fi;
- Mobile Internet;
- GPS;
- phone module (if there is a SIM card).

It is recommended to enable these functions only when they are needed.
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 reason for rapid battery depletion can be the screen backlight. It is this function that consumes about 57% of the charge in any technology. If possible, you need to set the backlight level to minimum or medium. Many tablets have sensors that change the light level automatically. If external lighting does not need to change the screen settings, then this function should be disabled, because it also adds load.

There are also cases when the tablet lies idle and the display lights up. Therefore, you need to install automatic blocking. This will not interfere with video games and browsing the Internet, but when reading books, this function can be disabled.
Adjusting the screen backlight is one of the easiest ways to save battery. It does not require special knowledge and tools, but it helps 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 parameters by selecting minimum or average values.
How to change the battery in a tablet?
Replacing the battery in a tablet is not the easiest task, even if you have the skills. This is due to the fact that the battery is built into the body and segmented batteries are used to make the device lighter. And it is not so easy to remove, even if you managed to open the back cover of the device.
The battery must be removed carefully so as not to break the cable, especially if the batteries are glued to the case. The same applies to installation, which must be carried out as carefully as possible. And if you are not sure that you will be able to do it yourself, then it is better to contact a reliable service center.
How to choose a Power Bank for a tablet?
As mentioned earlier, the tablet needs to be charged somehow while on the go. And one of the easiest ways to do this, especially if you have to spend time away from civilization, is to use a Power Bank or external battery. This is an ideal power source, especially considering that its energy capacity can be 3-4 times higher than that of the tablet itself, which means it will be enough for that many charges.
Therefore, when choosing a Power Bank for long trips, you need to focus primarily on this indicator. Energy intensity is measured in milliamp-hours and it is necessary that the external battery be capable of delivering at least 20,000 mAh. It is also necessary to pay attention to models with a charge release controller or several ports with different current strengths (A) so as not to harm the tablet and charge it effectively.
Wireless communication modules
One of the most common reasons why a tablet quickly runs out of power is when wireless modules are turned on. It's no secret that connecting to the Internet is a strong blow to the autonomy of the gadget. In the case when Wi-Fi, 4G module and Bluetooth are turned on at the same time, the device can die very quickly. Experienced users have a rule of always keeping Bluetooth turned off, and when leaving the apartment, switch from Wi-Fi networks to mobile Internet.
Important! In the case of mobile networks, you should know that searching for available connection points is a very energy-intensive process, and if the connection is unstable, it is recommended to stop using the Internet altogether. For example, on a trip, when the connection appears and disappears.
Regarding Bluetooth, it should be noted that modern devices have different versions of this wireless module. If the instructions for the gadget say LE next to Bluetooth, then you don’t have to worry that it will drain the battery . The abbreviation stands for Low Energy, that is, low consumption. In this case, the node is designed for constant operation, for example, to connect a wireless headset and there will be no serious battery consumption.
