I'm still having the same problem with my S680. I went to the Lenovo after-sales service center for warranty and replaced a motherboard.

Go to customer service and ask. It may be because you often play with the phone while charging the battery capacity is reduced, the phone battery should be able to be removed, you go and replace it.

Dear Lenovo users, when the battery just starts to discharge after being fully charged, it will not be charged immediately in order to prolong the life of the battery.

This should be a normal situation, and the safety mechanism may be triggered when it is charged to 97% to ensure that the battery is not overcharged. Try charging it for another two hours to see, if it doesn't work, it may be that the battery calibration is wrong, and you need to recalibrate the operation, etc.

The reason why your Lenovo machine is not fully charged is related to the battery, and the reason why you are not fully charged is a battery problem.

The battery of Pisen is a type of battery, the cavity capacity is exactly the same as the quality, and the branch key is not a lot of items.

Just turn off the "keep-awake" option for the developer option in that setting...

Check to see if there is any relatively large program running in the background of your phone, and if so, turn it off! In the past, my mobile phone was like this, just turn it off, and it is best to turn off the phone and charge it, which is good for both the phone and the battery!

It may be that you haven't activated the battery before, and the first time you charge your phone, you have to use the system to prompt that the battery is insufficient, and you are charging, otherwise there will be problems, and the battery will not be durable. Lenovo A789 mobile phone is charged to 99% or can't be charged to 100%, if it weren't for this reason, you will wait and see if it is charging. Hope it helps.

You have uninstalled the updated Lesafe and try again.

Dear Lenovo users, Hello.

We apologize for the inconvenience.

1. Please use the original charger and data cable for charging, if it is the original accessories for charging, you can replace other data cables if possible, in order to rule out the abnormal accessories;

2. It is recommended that you try to change the charging environment, and it is best to use the power supply for charging to avoid unstable voltage and current;

3. If you are powering on the phone for charging, please close the background program or restart the device for comparison, it is not excluded that the background program will consume more power;

4. It is recommended that you compare the charging in the standby state or the shutdown state to avoid charging the model while operating, which will generate the corresponding power consumption during operation, so as to prolong the charging time;

5. It is recommended that you back up the fuselage data and try to restore factory settings to rule out the impact of system abnormalities.

If it cannot be improved after resuming operation, it is recommended that you take the time to go to your local Lenovo after-sales service center and let the engineer help test and solve the problem.

That's right, it's full.,My Samsung charge is 98% overnight and the next day.,This has something to do with the software system you use.。

Try installing a battery calibration program!

It's full, it's full! Unicom machine is a bit of a pit!
