This situation may be caused by battery loss, we can try to calibrate the battery, then open the \"phone\" software, enter \"*#*#2846579#*#*\
< br >
Then in the \"Project menu\" interface, we can see that the last option is \"recharge\
< br >
We can see that the current page prompts \"Please ensure that the battery charge ratio is between 60 and 75, and the battery temperature is below 70°\
< br >
Wait for the recharge to be completed, about a moment later, do not wait until the battery is full, it will show that the recharge is complete, so that it is OK, and then connect the charger to see if the problem is solved.
