Lenovo S850 phone drains battery very quickly

Dear Lenovo users, hello!

Dear Lenovo users, hello!

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 can appropriately reduce the screen brightness (Settings - Display - Brightness, you can manually adjust or check Automatically adjust the brightness);

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 to specifically test and deal with the battery, etc., to see if the battery is aging, the charging circuit is abnormal, etc. Official website authorized maintenance site inquiry:

You can also see if the background running program is turned off when the phone is in standby, and the background running program is also consuming power.

If the power consumption is still high, you can back up contacts, text messages and other data, and then restore to factory settings.

After resetting the factory settings, and then standby for a period of time, if it still does not work, it is recommended to contact the local site maintenance station to test the phone.

Lenovo authorized repair site inquiry.

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

Both. 1.The quality of the battery cells is not very good, and the storage capacity is limited. 2.The hardware power consumption is not well controlled, and the power consumption is large3System optimization workmanship is not good, and some software needs high power consumption to run.

If the phone consumes a lot of power and has a short standby time, it may be related to the operation of the phone or the battery, so it is recommended that you try the following actions to reduce it.

Battery wear. 1.When the device is not in use, it can be switched to by pressing the power button.

Hibernate mode. 2.Turn on power saving mode: Settings - (General) - Power saving mode - slide to on. 3.Pass.

Task Manager.

Press and hold. home button.

Two seconds) to close unnecessary applications. 4.Turn off settings such as Bluetooth, location, push notifications, etc. to extend standby time without affecting usage.

5.Disable the auto-sync feature of the app. 6.

Reduce backlight time. 7.Turn down the brightness of the display.

8.If possible, try to replace the original battery of the mobile phone.

1.It is judged that the heat is larger.

Remove the mobile phone protective case, and by touching the back position, determine whether it is on the battery or the mobile phone circuit board.

2.If the battery is hot.

Then it is also possible that the battery has started to have problems; In some cases, more attention should be paid when the battery swells; And if the decline in power consumption is sometimes fast and sometimes slow, then the battery also generates virtual electricity, and it is necessary to make a better new battery to prevent the battery from swelling due to battery overheating.

3.After ruling out the battery problem, check if there is a software problem.

Sometimes, the mobile phone screen also consumes power, but it will not occupy a particularly large amount, and there is software on the network that can reduce the frequency of the mobile phone, but the effect varies from system to system. The common practice is to turn off the auto-start program directly, which is still a bit preconceived and not very accurate in this way. The recommended practice is to check the battery power consumption capacity to Android has a battery power consumption test report, in the system settings "Battery and Data Management" battery, check the right"Battery usage", you can clearly see the power consumption of the screen.

You can clearly see the power consumption of each application.

Judgment **Power consumption:

Usually the screen consumes the most power, and if the screen consumes a lot of power, you should choose the infrequency reduction software.

If there are other power consuming more than the screen, you should choose to use the root tool to turn on the permissions, and then use LBE to disable the self-starting program (especially this power consumption is larger than the screen), and turn off the wifi and GPS that you don't usually use, and then turn it on when you want to use it.

What if the power consumption is not the screen, but you can't find out? Take a look at step 4.

4.Power consumption is not at the discretion of the system program itself - it may be caused by flashing.

Have you flashed your device recently? If so, it may also be that there is a problem with the system itself, and the solution: save the data and use the mobile assistant to re-swipe it again.

5.Power consumption is not judged by the system program itself - it may be caused by phone parts.

Whether there has been water or a collision with the mobile phone recently, causing a short circuit in the part, which causes heating.

In this case, you also need to find a mobile phone manufacturer to do the maintenance.

6.Power consumption is not judged by the system program itself - the overall response speed of the phone.

Some people will put a variety of accessories on the mobile phone, such as the mobile phone case, which will lead to poor heat dissipation of the mobile phone, which will lead to abnormal heating of the mobile phone; After eliminating the above problems, what you need to judge this kind of problem is to remove the phone case, accessories, etc., and wait for 1 day to feel whether it is caused by this problem.

With the above six, the problem of fast battery consumption of mobile phones can basically be solved.

I hope the above is helpful to you, if you agree with me, for the satisfactory answer, if you have questions, please add.

Check to see if the battery is not durable, or if the phone is draining or leaking.

Dear Lenovo mobile phone users, hello!

We apologize for the inconvenience caused by the use of your mobile phone.

Due to the characteristics of Android machines (high power consumption), under normal circumstances, standby use is about 1 day. It depends on how you use your phone.

At the same time, you can also check whether the power consumption is due to the large number of programs or services (WLAN, GPS, Bluetooth, etc.) that are enabled in the background.

In addition, it may also be caused by abnormal system battery metering data, it is recommended that you back up the important data of the fuselage, and then restore the factory settings of the mobile phone to see if it can be improved.

If the problem persists, it is recommended that you take the time to go to your local Lenovo after-sales service center and let the engineer help you detect and solve it.

You can log on to the official website to check the address.

It's really not durable. Always bring a power bank with you.

The Lenovo S850 comes standard with a BL220 2150mAh capacity, which can generally be used normally for 2-3 days when fully charged. For the specific use of mobile phone power, this needs to be based on a use of your mobile phone to judge how long the battery can be used after a full charge, because it is not clear how you use it, so it can not give you a clear use time, please understand.

It depends on how you use it, if you watch a movie, it is estimated that it is more than four hours, you play games to last a morning, landlord, you try to match as many batteries as possible, the super core of this battery can be handled, I hope it will help you.
