I am having a weird battery drain on my find 7a . Sometimes the battery drains normally , but sometimes it drains ridiculously fast. I have checked the "wake lock" but there is no app that is causing it. On the other hand the Android OS is eating up the battery in the abnormal drains. I think but am "not sure" it has something to do with Charging, because when i charge it with a normal charger the batterry drains normally. When i charge it with the VOOC charger, sometimes it drains normally sometimes it doesn't. Even the diagnostics with wakelock and CPU spy aren't helping.
I am on Color OS 1.2.01i.
