Shure but as it is an official OTA release for FF3 sold by e I think this is an issue. I use the final release not the dev release with OTA update. Usage is minimal. However it is not possible since the update to charge the phone while it is on. I have to shut down the phone, remove battery and reinsert and charge while phone is off (not booted). It will only charge to 100% this way.
Yes. No usage. No app running. Battery usage shows no exceptional usage or APP in the background, just by leaving it on the table it looses 20% weithin 30 min. All happening after OTA.
