I had already googled exactly the same search and I found exactly that.
I disabled Google Maps (the result is a complete uninstall, do not ask me why you can not simply disable it) and now the problem is the wifi. It seems that one of the apps is trying to use location and or data all the time. I will keep an eye on the Apps that I recently install since this was not happening al the beginning, with a clean installation of android 6.0.
The funny thing is that location is deactivated for all the apps and was only allowed in the google maps app. It seems that some Apps do not take in account that location is deactivated and keep trying to access to it therefore consuming more battery.
Could this be related to other users concerned about wifi being the main battery drain?
Can’t find the three dots anymore.
However I can access the parameter via
Settings > Search (the magnifying glass icon on the upper right) and seaching for “scanning”
Would not help, my phone language is in English, only the keyboard is Swedish, not evident from my screenshot I see…
It seems that my phone is still indexing the setting chapters, when I started searching for scanning, even putting only ‘s’ would not give me anything, even though a lot of the settings start with ‘S’. But now after messing around a bit I get the results “screen lock” “SIM card lock” etc. Seems the list is increasing. Which is weird, since I’ve had Marshmallow since FP released it a couple of weeks back. Maybe if I wait a while
But I found the setting under WIFI instead:
When disconnected from WIFI i had a small text in the middle of the screen beneath the text “To see available networks, turn WI-FI on” looking something like this:
“Your WIFI is disconnected. However some apps may still use it to improve location, go to Scanning to change this setting.”
Now I cannot find the setting anymore since I ticked it off… But I don’t need it anymore, so I guess the problem is solved for me =). Would be nice to be able to access that setting though…
After uninstall some apps, it seems that Accuweather was responsible for the battery drain. I assume that it was trying to get my location with maps and then with wifi. Even when I did not allow this app to get my location.
Now without that app everything seems back to normal.
3-4% of battery lost overnight with flight mode on.
I see, I would consider this a bug in that case, @paulakreuzer?
At least there still is a way to locate the setting if it is turned ON.
See my previous message:
I’m no longer the gatekeeper for bug reports, there is now an official bugtracker. But as you can see in the first post this issue has already been reported there and was dismissed as an Android issue which FP can’t fix.
PS: Oh you were talking about the missing setting. Yeah that would be a separate bug. See if it hasn’t been reported yet and if not please report it.
If it’s indeed the same issue, just with different symptoms, it will be rejected again for the same reason or marked as a duplicate and closed. If it’s a different issue, then well, it’s a different issue.
So either way it makes no sense to mention it in the top post of this topic.
Checked out the instructions and followed them where possible. Not all of the options are available on FP2 with Android 6. Still the wifi module is the top battery drainer, even though it is generally deactivated, except for FP updates.
Indeed, it was the WiFi scanning. Now battery use seems better. I assume an app was scanning for wireless networks in the background even with WiFi turned off. Thanks again.
Hi,
I have been experiencing the same problems this week: battery drain that seems to be caused by Wifi even if it is supposed to be off (Wifi scanning was also off), phone hot on the back. I have seen this at least 4 days in a row. No big changes lately (update applied in July). The only thing I could think of was some new app. I suspect Chrome: I am on Fairphone Open and uses Lightning but I had to install Chrome to set up an app and I forgot to uninstall it right away after the set up.
Anyway, I uninstalled the 2-3 apps I had installed lately, I cleared the cache of all apps (via settings/storage), I made a battery reset (when my battery was empty) according to these instructions:
Today, the phone is not hot, no wifi shown in battery usage and it appears to be no battery drain.
I don’t know if it can help someone, as everything I did had already been advised on the forum, but I just wanted to give a positive feedback!
I don’t know if Chrome was responsible, but I like to think that to comfort me in using Fairphone Open OS
I received my Fairphone 2 only a couple of days ago with OS 17.11.2.
I experienced the Wifi battery drain issue and proceed with described solution by Tom’s guide.
It worked partially and it needs an update:
STEP 11: the three dot menu in the “location” setting is gone, in order to find the “Scanning” menu I had to use the search line in the main setting page (in italian, my language, goes under the name “ricerca…”)
After following the guide the situation got better but not perfect. sometimes the wify gets stuck on “active” even after turning it off.
It needs a reboot to actually go “inactive”.
