Fairphone overheating with rapid battery depletion. Seems to be browser.
-
Hi all,
Twice now, my Fairphone 2 has lost all its charge in about fifteen minutes when I've been using the browser. The first time, I had it plugged into a speaker and was playing iplayer through it, so I didn't notice the alarming heat, focussed on the top of the phone, above the battery, until I investigated the sudden interruption of my listening pleasure.
This morning, I was reading the Guardian, going through quite a lot of pages, when I realised it was getting very hot. I shut it down and took off the back and the heat, again, seemed to be coming from the top unit, above the battery.
I gave it half an hour's charge, turned off, and it has been fine today. I've had to make a couple of calls and have had Nextcloud, Decko and a couple of other apps open. No problems, and the battery seems to be behaving normally.
Has anyone else seen this happen?0A user, not a coder. I bought a BQ Aqaris with Ubuntu on it, despite being outside the 'Ubuntu Insider' nonsense, and managed to brick it trying to make it into something useful. Delighted to find UBPorts. I'm really impressed with the community.

@danceswithcats what UT version? which browser & what version? were you using wifi or mobile data when browsing?
Edit: maybe is this? https://github.com/ubports/ubuntu-touch/issues/400

My FP2 is also getting very hot above the battery (right of the camera), but I thought it comes from watching videos, for example on youtube. Not shure what module lies there
It also drains the battery a lot, but I don't think it's empty as fast as yours.Perhaps its just a browser issue with html5 players...
but since my FP2 can't play back video files from "disk" I cannot confirm my guess.Edit:
After clearing my gstreamer cache (https://github.com/ubports/ubuntu-touch/issues/661#issuecomment-401391699) I could confirm, that my FP2 is overheating on html5 playback.I played the same video with UTmedia app (html5 player) and with native media player:
- html5: gets very hot, nearly untouchable
- native: gets warm
So for me, I suggest it has something to do with hardware acceleration not working for html5.
Otherwise, if @Danceswithcats did not play back any media in the browser, this could be a general issue in the webapp(-container).btw: I'm on 15.04 ota3.
