Fairphone overheating with rapid battery depletion. Seems to be browser.

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?

@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.
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.
