I am facing the same issues. Installing a new gaaps pico version improved the behavior but I still have the feeling the CPU did not become that hot at fpoos based on Android 5. The power consumption is still dramatic if I use the phone to stream videos or if I use the phone for navigation.
The upgrade from Android 5 to 6 worsened the situation. I would appreciate a bugfix very much.
OK did all that… Phone’s upgraded and gapps installed.
This seems to have made things a bit better WHEN PHONE’S NOT USED!
As soon as I use the phone battery consumption is disastrous…
I still think that this is NOT application related and that there’s something seriously wrong with FP2.
So conclusion : as long as phone is not used battery is OK… Unfortunately I don’t need a phone I don’t use…
I’m really sorry to say but it may be the end for me… My hope was that FP1 could be upgraded, well this ship has sailed (FP1 is the best phone EVER and I love it!!!) and FP2 been giving trouble right out of the box and till now… Completely unreliable…
Anyway…
Hello. I have the same battery problem. Before the update 17.4.8 it was the display that consumed the most, according to the indications of Parameters / battery. Then it was wifi. I tried all the save-battery tricks without improvement. I tried too Xposed Installer Smart Network module, who should cut wifi and mobile data when the screen is off, no more improvement. According to the statistics of consumption the wifi is always in function, even in airplane mode! In this screenshot phone was in airplane mode since 15:00 to 16:00, but wifi is always on
I would like to install Lineage OS, but it uses the same modem drivers: will there be an improvement?
We need a solution.
My problem exactly!!! We definitely need a solution…
I had the same problem with WiFi always on, now it’s gone. Take a look at this post, maybe it could help:
Thanks chrisse, I already noticed this post and tried all the suggested tricks. I installed yesterday LineageOS and now Wifi is no more on all the time.
What I still have no explanation for is the following:
- When I charge my phone while it’s turned off, the charging is super slow or does not happen at all. But the phone (CPU) gets hot.
- As soon as I start the phone, the charging starts at a normal speed and the phone (CPU) cools down.
This can hardly be due to a background process running.
Any ideas?
Of course I take the easy way and don’t charge my phone turned off anymore. An explanation would still be appreciated.
Anyone else seen this before? Phone had been in the whole time in a bag and unused (mostly). Picked it up to see it was at 1% which seemed odd
I rebooted it, and turned battery saver off and I’ve been using it solidly for ages now on 1%…
my battery is totally empty, but when charging my phone turns it self on. This costs too much energy and the battery gets empty again. so, now it is in a never ending loop…How to get out of it?
Maybe to kickstart the battery helps:
- battery out
- connect phone to charger (without battery)
- wait 20-30sec
- put battery in
- charge until 100% (if possible)
It could also be that your battery is broken does not charge anymore. Do you have someone with a Fairphone to try a different battery?
I guess you are using the same charger as always?
Otherwise it might as well be, that you happen to use a usb cable that is working for data connection only.
It is not just FB.
It is all kind of always-on cloud programs including FB Messenger (even “Lite”), E-mail (reduce amount of times it scans per hour and clean up your mailboxes), WhatsApp (and WhatsApp Web), Buienalarm (warns for rain in NL), Google Keep, Google Now.
What I do is:
- Put Brightness on ~25%
- Put Location on “Device Only”
- Keep Wi-Fi on during sleep on off
- Disable/uninstall all these applications, or as many as possible
- Greenify on many apps
As for Firefox, use Firefox Sync and move the tabs to your PC/laptop/tablet ASAP. Don’t keep tabs open unnecessarily. Consider to use Firefox Focus, it only supports “private mode”. Also, use uBlock Origin to block ads. Firefox 57 is out half November and will make Firefox on PC/laptop much faster. I don’t know when these changes are ported to mobile version of Firefox though.
I know there is a bug in Android 6.0.x with battery so I wonder does LineageOS users also have issues with battery?
However my battery has gone through roughly 500 cycles already. It is due for replacement.

BTW, if anyone else is using https://ring.cx/, I installed it a few days ago, didn’t use it after registering my username, and my phone started draining very fast even though the app was “off”. When I looked at battery usage it was responsible for 20%
Since I had no use for it yet, I quickly uninstalled it

I would also get rid of the default facebook app and use Metal for Facebook and Twitter.
Just because I wasn’t writting here doesn’t mean that everything is OK… but I have to show you this. Since yesterday…
Haven’t changed a single thing… they are no new apks, no different use of any kind. Just woke up and checked my mails… Now I have to charge it 3 times per day!!!
This phone is a disaster…

It looks like it’s mostly searching for GSM signal. Could there be a strange setting there?
EDIT: Also, what OS are you on? I don’t have that kind of icon. Are you on LineageOS?
Yes I know it has probably something to do with the GSM signal but can’t figure out why…
My phone runs on fairphone open.
