I've searched the forums about battery drain problems regarding android phones in airplane mode but each subjects seemed different to mine.
I own a Samsung Galaxy S3 LTE i9305 under Android 4.3.
The phone is rooted, Greenify installed, hoping saving battery life but...
I've tried to do a full data reset + reinstallation of Android 4.3 official, with no success.
I've done the folowing experience 3 times with the following similar behaviour as last time :
- Phone fully charged before to go to bed, Airplane mode activated.
7 hours later :
- Battery is at 80%
- 0 minute in deep sleep, all the time in awake state.
Several behaviours noted by Wakelock detector and Gsam Battery Monitor :
- Device Idle and androidOS consumed 80% of the 20% used
- Misc processes seem to have used a lot of battery among them :
I'm including screenshots to illustrate all this.
If anyone has been thru this problem I'd be glad to know how to solve it.
Thank you !
