Hello! Iâve got a mysterious problem⊠during the night, my batterie lose 10 at 25% for nothing! Iâm disconected about wifi or 4G and it doesnât work better. I donât understand the problem⊠Please! Help me
Hi. Can you look into âBattery Settingsâ to see whatâs consuming so much power? To do that, go to battery settings, click on the 3 dots on the top-right corner and click âbattery usageâ. Youâll now see what app is consuming. If itâs not an app, you can once again click on the dots on the top-right corner to switch to hardware consumption.
Maybe youâll find some information on those two screens. You can maybe post a screenshot here in order for us to check?
Putting apps to sleep if not in use (not just close the gui) can help.
There are apps doing this automatically (e.g. Greenify), but more recent Android versions (Nougat+) should do a pretty good job on this already, not necessarily needing such third party apps.
On my FP2 with Marshmallow the MXPlayer app keeps hammering my firewall wanting to access the internet. But putting it to sleep (force stop, not just select quit in the menu) prevents it to drain my battery over night.
Do you keep your phones in airplane mode over the night?
Standby mode not necessarily mean the phone strictly is going into sleep mode.
Often auto-updates are being made over the air in night hours too maybe draining the battery or even put an updated app in an undefined state until the phone is restarted.
I have a similar issue.
I didnât notice it during the first months. It started about 2 months ago. Sometimes (not every day), my battery is discharging very quickly.
What I have noticed until now:
in ânormal conditionsâ, the battery can lasts about 50-60 hours. Wifi enable during day, airplane mode during night, no big use of data or application.
sometimes, the battery discharges very quickly. It can happen during the day or night. In these times, the back of the phone seems hotter than normal.
when I notice the battery is discharging too quickly, I reboot my phone and the problem solves.
I guess there is some sort of application or task running in the background which consume the energyn (thus the issue solved by a reboot??). I canât remember any new application downloaded at the time the issue appeared. I donât remember any system upgrade at this time either.
I will try to check the battery setting and monitor if any app is involved in this and will keep you informed.
In the meantime, if anyone has some solution, Iâm keen to have them!
Perhaps you could try, if your phone is rooted, to observe the output of the top command as superuser in a terminal (Termux is good). It shows the processes using the CPU, and it could show you if something is draining you battery by using the CPU. Otherwise, you can also download Better Battery Stats, it does it as well I think and more easily, although Iâm not sure about it (but again your phone has to be rooted).
If you donât understand, or it seems too complicated for you, and you donât feel to do it, donât do it and forget about it (if needed I can give further explanations but Iâm not really a specialist).
Itâs very difficult to see what uses your battery. So a battery drain can come from different things. I had a problem like this and it was the motherboard the problem (Process irq/288-wcd9xxx draining battery), but for others it can be the battery, a module or even the software. And rooting your phone would allow you to have a little idea of what drains your battery so much. So except if itâs something very simple, very few methods will be efficient to find out. And nearly all of them (if not all) imply rooting your phone.
But indeed, if you donât feel like doing it, itâs probably better not to do it, because rooting can cause problems if youâre not careful.
I experience exactly the same issues that SimonL. Iâm not an expert so it could be dangerous to proceed to rooting. Can someone at Fairphone provide solution to resolve these repeated issues ? Many thanks in advance
They may be able, but maybe not. And if they donât know, theyâll probably want you to send them your Fairphone for repair (which finally may be the best solution).
