Recently I've realized that my 15 month old LG G4 seems to have an issue with the battery in cool or cold weather: dry, no significant windchill, +5°C/+41°C
In at least 3 instances, it happened to drop from 50% or even 65% charge to zero, rebooting without warning. I've not seen issues at other times (higher temps)
I can even reproduce this:
- Have the phone at 50% to about 70% charge
- go outside if its around 5°C
- take a couple of pictures with Open Camera.
After a couple of minutes, it will reboot and only have a fraction (<10%) of the charge, and keep rebooting if I try to take pictures.
I've tried all the "battery reset tricks" out there, but as I said above - I don't have any issues other than in the cold (+camera).
Is this expected behaviour or should I replace my battery ?
Do I want too much from my smartphone ?
Should I scale back my settings to try and keep the power draw lower ?
It's a Li-Po 3000 mAh (original) battery
Android 7.1.2 (LineageOS 14.1)
Open Camera settings: High Res (16:9 15.87 MP), 90% JPEG, GPS on, 100% display brightness, background thread, no flash
I'm also uploading the pictures to owncloud via the owncloud App ("Instant Upload") over 3G/4G
Here are some graphs from GSam Battery Monitor.
If you look at them closely, it seems to "recharge" around 5% if its in a warmer environment again.
