Hi there! My FP2 OS drains battery very fast. Even in plane mode, the phone can pass from 80% to 70% in few hours, while a few months ago it was kept at 80% all night in plane mode. Somebody with the same problem? When looking at battery use, miscellaneous is on the top of the list (sometimes more than 100%! :-S and other apps at 10% or 20% at most ). Any idea what is happening? In developer options I can see that settings is the one using more RAM.
It seems that “miscellaneous” is now called “over-counted” in Marshmallow.
I’m having trouble with “over-counted” battery usage these last days and I also have wifi under battery usage, even if I don’t use wifi (and no location services either that could use wifi). I am on open 17.07.6.
EDIT: The proximity sensor is causing a wake lock. So I removed all apps listening to the proximity sensor while the screen’s turned off and that solved the battery drain problem. Is this wake lock behaviour intended or is it a bug?
Hi! I believe nobody found any solution for this problem… I’ve tried to see some patterns… What I saw so far is the following. First, not always but sometimes battery drains very fast, even in airplane mode. The only exception is when phone is in “battery economy mode”. This is the only thing that prevents battery to drain fast. I’ve tried apps to track battery usage, greenify, etc… I’ve found a workaround that works: Go to developer options/running apps/ click on “settings” and stop it. This solved my problem. Seems that take a look to battery use makes battery to drain faster in my case
You found an interesting information about battery drain in Android 5, which Google announced to fix in Android 6 according to this article from 2015 .
“Many users have been experiencing a battery draining bug in Lollipop caused by the device’s radio remaining active for too long, but only now is Google doing something about it. The fix is expected to roll out in Android 6.0.”
haha yes you’re right!
I meant that, as they mention “is expected to”, it is possible that this problem was not fixed (or has been fixed in more recent Android versions instead of 6.0). Because I’m using Android 6 and, as far as I can tell, I’m having the same problem. Maybe fairphone developers could take a look at it; it could partly explain the problems with battery drain that we are experiencing.
I have installed 7.1.2 open edition.
I don’t know if it is the same bug but I get a really high miscellaneous power usage. Currently at 72%. The power usage is so high that the power supplied byan computer USB plug is not eenough not only to recharge but even to maintain the battery level. Yesterday i plugged it into my main desktop and this morning the battery was completely depleted.
The CPU also get really hot. I tried to slow the CPU down using Kernel adiutor from Fdroid repositories switching off 2 cores slowing it down in the range 300-1500 MHz and using power saving CPUgovernor. Of course those are not solutions. Luckily I’m at home healing a sprained ankle so I have plenty of time to help sorting out this issue.
Thanks in advance for your time
I tried removing OpenGApps and it helped.
I thought everything returned normal, yet I still see an abnormal “Miscellaneous” power usage, even after removing MicroSD as paulakreuzer suggested.
I just can’t remove the SIM card as I need to actually use the phone. I’ll move it into the other socket to check if it improves the issue.
