Battery is drain too fast even when not in use
I'm having problem with my iPhone 5s. All of a sudden, the battery is draining way too fast and the device is not accepting any original (apple) lightning cable than a third party lightning cable. The battery would drain even when the phone is idle and battery level drops from 90% to 10% overnight. What should I do?
I know a friend with same problem. Even after changing the charging port and the battery , The device is in the same condition.
So, Is it a motherboard problem.
FYI-I have already tried resetting my device and unistalling all the apps.
Is this a good question?
