Steep decrease in Battery Percentage

[suga49]

Hi Everyone,

Am facing a problem for past one month. In the night before hitting my bed I switch to airplane mode and keep the mobile away. when I get up in the morning, the battery percentage drops to 5 to 6%. I dont mind this small percentage. But when i check the graph its showing me that there has been a steep decrease at a point and thereafter battery line is straight for many hours. What could be the possible reason. Please help me. Thank you.

Hi suga49,

It seems you have sudden drop issue....pls follow Nabeel's instruction:

Do it when it is 'ON'...

although the vibration happens even when the phone is 'OFF'....note the battery percentage before doing the procedure, and observe when you switch on. If there is significant drop in battery percentage...your problems are over. If not..try a few times more.

Let us know whether it solved or not ...
