[Q] Galaxy S3 LTE i9305 Battery drain (Even in Airplane mode)
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 !
