Fairphone gets very Hot and Battery drains quickly

Do you happen to use a big SD card (I mean with a lot of data stored on it)?

When the battery haemorrhages this quickly, which apps are running (even when in the background)?

I noticed also, that after update to 1.8.7 my phone is taking battery more than 50% a day, before it was between 12…25%. No changes in my behaviour or new apps (except of course Google apps)

Maybe I can link to this old topic, at which similar complains after Updates to Cherry 1.6 popped up:

@Bix: Especially at this post I still recommend the App “BetterBatteryStats” (find in XDA-Forum for free), to check, if any app is running at 100% CPU load while phone should be in idle (so-called “wage locks” in this app).

Hi, this may sound strange but I had this problem with my phone of getting too hot and draining the battery after a few hours while in holidays in Spain. After coming back to the miserable weather in Ireland, all was back to normal. So fine for me but I am thinking that shouldn’t recommend Fairphone to my Spanish friends!

I don’t know how hot it was in Spain exactly but that might also have to with the usage of the SIM card(s) or something like that. Any ideas from others?

Some news on the heat problem. As I reported in January last year, the problem was gone after I changed the SD card. Still the phone got hot again from time to time, but not so much I was looking deeper into the problem. But since a month or so it started to get hot almost always. I started changing and/or removing SIM and SD cards again, but nothing helped.

Finally today I installed a CPU tool (OS Monitor) to see if there might be an app that drains my battery. And really, “Pocket” took 25-50% CPU load! After I uninstalled it, I found “IKEA App” to take another 25%. Now my phone is “cool” again :slight_smile:

That’s good to hear.
And I think most of problems of this kind for FP1 and FP2 can be solved the way you did and I frequently suggested :wink:

Hi! I have had my FP 1U (I think) for approximately 1 year and something really annoying started happening yesterday. I put my phone on charge when it was at about 5% over night so that it would be 100% on the morning. When I woke up it was on 100% and I watched some videos on YouTube, but I got interrupted by the “You have 15% left” warning after using the phone for maybe 1 hour, not more. My FP can usually go all the day with severall hours of usage before reaching low %. After I got warned I put the phone to charge while I ate breakfast and when I got back, maybe 30 minutes later it was on 100% again, so i tried to use it again, but the battery drained almost 1% in 30-40 seconds when I used it. If someone knows the solution for this problem and if it can be fixed or not, please, answer!! I can’t go through a whole school day without the phone running out of battery, even if i’m not using it!

If you did not install new apps (which could drain your battery) it could be that you have to replace your battery.

Before ordering a new battery you could try a battery reset:

You can order a new battery here:

Check if its bloated:

If you still have warranty (2 years) you’ll get a free replacement.

@Irina_Spitznagel is right, in your case it could be the “bloated battery” problem and you should check this first!
