Lenovo A390T s power consumption problem is serious, how to solve it

Disable the background auto-start app, go to Settings, see which things are draining a lot of power, and change the battery.

Hello. We apologize for the inconvenience.

2.Whether you use it for a long time, using large apps or making calls for a long time will consume a lot of power, it is recommended that you adjust the screen brightness appropriately;

3.If you have the conditions, it is recommended that you replace the battery for comparison, which is not ruled out due to battery aging or abnormality;

4.It is recommended that you close the system background programs regularly, or you can use the "Phone Acceleration" function in Le'an.

5.It is recommended that you use Le to save electricity, this is a power-saving and energy-saving software officially launched by Lenovo, you can go to the Le store to search**, and Bluetooth, GPS and other functions are recommended to turn off energy saving when not in use.

If the power consumption is still serious after the above operations, we recommend that you back up the fuselage data and perform a factory reset.

If the problem still exists, please take the time to go to the Lenovo site for specific detection and processing.

You can access:

Find the nearest site. The business hours of the maintenance site are usually from 9:00 to 18:00 from Monday to Sunday, except for holidays, and the stations will be slightly adjusted according to their own operations.

If you need other help, you are welcome to contact us or visit Lenovo at any time

Consult to find out.

Get root and remove some unused software from the built-in.

Most of the battery is virtual when it is not fully charged, but it is not actually 30% charged.

Detect whether the machine head consumes power.

Check that the battery contacts are clean.

Check whether the internal resistance of the battery is too large.

1.The phone is in a poor coverage area with a weak signal, which accelerates the power consumption, and this problem does not occur in the normal coverage area.

2.The mobile phone antenna is not stretched out in use, which accelerates the power consumption, and the habit of pulling out the antenna is formed in the use of the mobile phone, which can save power.

3.New batteries or batteries that have not been used for a long time can not reach normal standard performance until the first three times of use.

4.Old batteries, or batteries with memory effects, will run out of battery power in a short period of time, and the battery will need to be replaced.

5.When a battery is used in extreme temperatures, high or low temperatures can greatly affect battery performance and require frequent charging.

It's normal, if it's not optimized yet, it's the battery.

2.Whether to use it for a long time, using large apps or Donglu luggage for a long time to make calls will consume a lot of power, you can appropriately reduce the screen brightness (adjust it in Settings-Display-Brightness);

3.If there is a condition, the replacement of the battery is not excluded as the result of battery aging or abnormality;

4.To check whether the power consumption is serious due to too many programs running in the background of the phone, you can close the background programs of the system regularly, or you can use the "one-click check-one-click optimization" function of the security center.

If the power consumption is still serious after the above-mentioned operation, back up the fuselage data to avoid the loss of important data and carry out factory reset.

Resume observation, if the problem still exists, take the time to the Lenovo site for specific detection and processing.

Here are some of the reasons why your phone's battery isn't durable:

1. The mobile phone battery is aging, causing the battery to not store power, solution: replace the same type of battery.

2. Mobile phone system problems, such as the mobile phone consumes too much power, causing the battery to be used up quickly, solution: save the power consumption of the hand-closed defense machine.

The method is as follows: a. Clean up the cache of the phone and exit without the software.

b. Reduce the bright car point of the mobile phone.

c. Reduce the volume of the mobile phone stove.

There are many mobile phone applications, and the power consumption is fast, and now the smart phones are like this, and the standby time is not long.

Hello, the battery life of the mobile phone is related to many factors, the following suggestions are provided for your reference for the problem of mobile phone power saving:

1.Maintain the battery, and the new battery should be used up first and then sufficient, then exhausted, and then sufficient. This goes on three cycles, one per month after that.

2.The brightness of the screen when the mobile phone is in use, the volume of the sound emitted, and the duration of the mobile phone are directly proportional to the power consumption. Therefore, some functions can be turned off when nuclear infiltration can be burned.

For example, the sound of power on/off, key sounds, animations, screensavers, etc., reduce the brightness of the screen, shorten the lighting time of the background light and keyboard.

3.When the phone is in standby, the processes that are not in use are turned off in time.

There are too many programs on the phone.

Lenovo A390T's memory usage is always above 88% because part of the memory is occupied by the system itself, so it can't be used and can't be seen.

The parameters of Lenovo A390T are RAM512M, ROM4G.

1. Cache, as long as the program is run, the corresponding cache file will be generated, this is stored in the ROM, the cache includes the necessary data files for the program to run and some account passwords, etc., if you want to reduce it, you can only clean it up often, but it will be automatically generated when you run the program again, A390T In addition to the system itself, there is about 2G left, and it will not be pressured by the cache problem.

2. Running memory is RAM capacity, A390T is only 512M, a bit small, multiple programs may be slow to respond when running, the memory management mechanism of Linux kernel is to automatically close the idle process when the memory is insufficient to make room for memory, of course, you can also manually close the idle program through the software to make room for running memory.

If it can't be lowered, the so-called one-click cleaning is basically useless. After all, this phone has a memory configuration of 512M. For Android, 80% of the occupation is completely normal, after all, the machine's built-in system files occupy nearly 350M or so.

The only way to do this is to flash your computer and get rid of most of the built-in apps, which will reduce the basic memory to 60%-80%.

It is recommended not to use third-party desktop software and plug-ins, and to turn off battery tools such as Lenovo Power Saver. Clean up apps often when you're not using them. The RAM of 390T is too small.

You'll have to see what programs are running in the background that can be cleaned up with 360

Hello. We apologize for the inconvenience.

1. It is recommended that you use the mobile phone acceleration function of security software such as Le'an, 360 Security Guard, etc., to clean up background applications, which can effectively release running memory;

2. It is recommended to uninstall useless or infrequently used software, which can prevent the self-start of such software and occupy running memory;

3. After the application is finished, try to use the exit function of the application to completely exit to avoid the application hanging in the background and occupying the running memory;

4. If you currently have security software installed on your device, and you have the function of setting the program on the device to start automatically, it is recommended that you use this function to observe the software in the mobile phone after booting and self-starting;

5. Back up your mobile phone information and restore the factory settings.

If you are worried about the problem of the device itself, it is recommended that you go to a maintenance site authorized by Lenovo for further system optimization or testing.

The amount of RAM in the running memory is related to the mobile phone stuck, slow operation, and crash.

RAM determines how many background programs can be opened, and the larger the RAM, the faster the phone will run and run multiple programs smoothly.

Some ways to free up running memory:

1. Restart your phone.

2. Use mobile phone management software to clean up cache and garbage to directly release running memory.

3. Install less software that starts automatically when you start (or use Phone Manager to close the self-start app when you start up).

4. Open the app as little as possible, use the settings --- manage the app --- running--- reduce or turn off some background running.

5. Back up your data and restore factory settings.

6. Root the phone (risk item), delete some system users can not use the boot auto-start application and reduce the system's own background and self-start running application.
