Same problem: Battery drains in 6-7 hours without me doing anything. Device gets hot, even without SIM card. Touchscreen is unusable sometimes. WLAN on/off messages (Toasts) are showing up for minutes hiding the virtual keyboard.
Update 1.2.8 did not solve any of the problems. No help from support (ticket #96059).
I put my phone out of order now, its just useless in this state. Bought conventional mobile to be connected again.
@Thomas_Nordmeyer: Maybe you can give also a try of remove your display-unit and put it together again, like @GMehn it did (see iFixit guides or some other in the forum), it could be connected with some bad connectors…:
If you want to try, please report back if you notice the same behaviour afterwards…
This thread and the information that FP2 may have trouble with some SIM cards may give a hint for some who have problems with overheating phone and bad battery life: FP2 kills some SIM cards
I’m not sure if there is a connection between theese problems. I didn’t notice a difference in battery lifetime without the faulty SIM. My FP2 lasts usually about 12-16 hours.
It’s not about a SIM being bad but a SIM having services that FP2 doesn’t support or handle properly. Nevertheless, that’s just something that seems to be affecting some people, and I didn’t mean to imply it would explain all problems.
as far as I know the “battery duration” is an estimated value based on the previous durations.
So I hope that the real battery duration is better than the shown one at the battery settings.
It’s a pity that your battery duration did not improve after removing the screen
In my opinion there are basically two main reasons for a low battery duration:
hardware issue (battery itself, screen, cpu, WiFi, etc. consume too much energy)
software issue (OS itself, apps that cause a lot of activity)
Sometimes it is very difficult to separate hardware and software issues and to find out the real cause.
Did you read this article:
from the Fairphone support team?
Another approach:
I did not try them by myself but maybe one of the mentioned apps can detect an app which is the reason for your problems (in that case it would be a software issue):
( Please be aware that you use this apps at your own risk!)
If you think it is more a hardware issue, it is probably necessary to replace or repair parts of your phone (e.g. new battery).
Did you contact the Fairphone Support team and have you already opened a ticket?
Maybe for a longterm observation this app is useful:
It records the charging state of the battery for a longer duration than the default battery stats (default is 1 week, but it can be set to 1 month or always).
I installed this app today and will post my experiences with it.
Should I put the battery in the phone and then start charging or should I start charging for a while and then put the battery in phone? Another person explained which steps to do and said I was to kickstart it by charging the phone without battery and then inserting the battery to give it a kick, but now i’m not sure which one is the correct way. Please tell me!
