Hello. My barely used G5 after full charge keeps discharging really fast(like 100% to 1% in 20 minutes) but after boot up the phone shows its real battery percentage (like 75% after first cycle) this continues on and on rendering the phone unusable. Here you can see an graph of battery usage, the phone wasnt connected to a charger during this testing period.I used an app to measure the battery voltage and the phone reads like 4.1 V at the first power off.(It shows like 4129.3V but it is bugged somehow it probbably reads x1000) So it is unlikely that this is caused by the battery(i tried two of them, the same thing happens)Have anybodey seen this before? Im thinking of instaling some custom os because this looks like software bug( i already instaled newest android updates).If you know how to fix this i woud be glad for any reply.
