Activation method is as follows:
1, it seems that in order to protect the battery, every time when the phone is used to automatically shut down, it will not be charged and enter the automatic hibernation state, which is manifested as the indicator light has been flashing red or the indicator light is not bright at all.
2, sometimes there is an emergency need to charge the phone immediately, the following is a solution:
3, plug the plugged data cable into the millet phone, then the normal indicator light does not respond or flash. At this time, open the back cover and remove the battery (the data cable is still plugged in).
4, if the screen is displayed as the boot interface, then the charging is successful, you can charge normally, reinstall the battery, the indicator light for normal charging slowly flash. If not, remove the battery again, normally for one success, usually no more than three times can be successful.
5, after the successful charging will become a normal charging interface, it is recommended that even if there is an emergency, such as electricity reached more than 4% and then boot. Do not think that the phone is broken when it encounters the situation that the Xiaomi phone automatically sleeps and cannot be charged, as long as it can be done according to the Xiaomi phone battery automatic sleep solution. For long-term lithium batteries that are not used for various reasons, the voltage will gradually decrease due to self-discharge, and when the voltage is lower than the minimum threshold voltage set by the lithium protection board (generally, the lithium battery ranges from 2.5V to 3.0V), the power output will be automatically cut off. At this time, the voltage can not be measured outside the lithium battery with a multimeter, and it can not be charged with a mobile phone and universal charger, which is called battery dormancy.
