Hi.
I usually put my Metal in airplane mode for the night.
Normally the battery drain in this mode for me is about 1% (max 2%) per hour.
I usually put the phone in airplane mode when at 100% battery level and about 6/7 hours after the level is 90/93%. Not good but also not so bad.
However, last night i did, for no particularry reason, this procedure:
- At 100% battery level i put the phone in airplane mode.
- Power-off
- Power on
So, this morning, the battery level was 99% that means that the battery drain was 1% in about 7 hours.

Pay attention: i haven't tryed to directly reboot phone, but only power off and next power on, so i don't know if this procedure works also rebooting the device.

I'll test again this night. If it works it's a good work around for the battery drain in standby mode.

Hi.

This is what i say. After a few hours the deep sleep not working,but if you reboot then it's work again. Try to disable screen rotating in settings/accessibility and in the roll down menu set portrait. I saw the log,and i see,the gsensor stay awake. I set this and this is the 3rd from last charge,now 21% only 2G mode,WIFI always on and FB,Gmail syncronise,GPS always on,but not used,fingerprint sensor off and gestures off. With lite use the battery consumption 1,4%/h. I use betterbatterystats.I sent an email to ulefone and sent my log from problem.

Thanks, I'll see if it works.

Too bad you can't use this through day, having plane mode and restart every time I want to stop using the phone for a while would be too time consuming.

Yes, obsiously it's a work around only for my particular case, when i need to put the phone in airplane mode for the night.
During the day it's impossible.
But for me it's however good, because i can go to work with 99% battery level instead of 93%.
It's not a big thing, but it's better than nothing!!!

I have have this phone with stock rom, latest, and i have problem with battery draining, or its normal, only 1 day normal use (for 3000mah battery its not normal), and when battery is 20% i have battery drops (from 20 to 1 only few mins in standbay). And second problem is when i call someone its show "unknown" doesnt show name from contacts, but when someone call me its ok, show name correctly.

For ZGFG. I'm using the last OTA update rom, always updated using OTA service, never flashed directly from PC.
Last night i have tried the same procedure but directly rebooting (not power/off and power/on), withe same results: only 1% battery consuption in about 6 hours  in airplane mode.
