Possible Solution
Please take out battery and insert again. Then press Power key to power
on the phone.
Charge battery. Check charging indicator on display.
Wipe the charging contacts, both on the phone and on the battery, with a
clear soft cloth.
If the battery time is short, it may be due to the user environment, a large
volume of calls, or weak signals. Turn off applications when not use them in
order to save battery.
Make sure the ambient temperature is right, wait for a while, and then
charge again.
