Battery problems (wrong charging status / battery might be dying)

:uk: No, you can’t buy the FP battery in Vienna. You can only order it in the shop.

:de: Man kann die FP-Batterie nur im Shop bestellen.

I noticed that the battery only drains from 15% to 0%, when the screen is on. When it’s off the battery doesn’t seem to drain (the phone is still on when checking after some minutes).

Can someone confirm this behavior?

Edit: It could be that it’s the display, which causes the battery drain.

No. My battery is one step further: drains regularly to 60% drops to 30% in some minutes and then dies.

I ordered a new one (1 year for a battery. None of my previous phones did it that fast. At that rate I expect that I’ll have to order 2 more batteries during the life-time of the phone. This messes up the ecological footprint of the FP)


My FP also starts at higher percentages with draining, but the question was if it makes a difference if you keep the screen off?

My battery seems to bloat.
I stopped using my phone, i only turn it on once a day to check messeges.
I think its the reason why my battery was draining so fast.
I submitted a ticket last friday, but no response so far.
I tried to call the support desk, but no one is picking up the phone.

I strongly suggest the people who’s battery is draining fast to check if their battery isn’t bloating or not.

Hope, they reply soon! Also check Battery bloated for further reference. According to a quote from FP’s warranty policy you need to prove that the bloated battery is a manufacturing defect (e.g. through a photo).

So if you have not attached a photo to your support request, you should do so, to ensure that your request is processed as fast as possible.

Thanks Stefan, i already spoke with a FP employee and there sending a new battery right now.

Just adding my voice and screenshots to the crowd. It feels like this started happening to me once I’d updated to 1.8. Once the better gets below about 50% a restart can cause the batter to show ~10% which then drains extremely quickly. Once it powers off, plugging a charger in till immediately bring it back with a chunk of charge!

You can see where I retarted the phone and had the % drop from about 50% to 10%. That then drained down to 1% and stayed there for a while. Once it finally failed, a 1 min charge restarted the phone with +10% again!

This one was me turning off the phone, putting it to charge for a bit then turning it back on. The battery level spiked from around 15% to 80% very very quickly.

My phone’s charge indication not only sometimes drops very fast into single digits until switching off itself at 3%, I also often experience it stuck when charging. For example last night I put it on the charger, it went from 3 to 18% and remained there for the rest of the night. Then, other times, it charges like others have described, with the indication jumping suddenly from ~14 to 50-70%. This behavior has started only recently, long after the 1.6 update…

Hi everybody…

I can’t stand it anymore.

I charge my phone 3 times a day and still can’t use it for a whole day. This morning battery droped from fully charged to 0% in two hours (!!!) and I didn’t even use it… just unlocked it once or twice.

This is intorelable… I don’t trust the indication, I don’t know when my phone’s charged and of course I can’t rely on it during the day as I have a lot of (bad) surprises.

I really need some help with it. Is it the battery or the phone problem? is there anyway to make it better?

PS my phone is first edition.

@evidemment - This really isn’t usual behaviour. How infuriating! My opinion is that it could well be a battery problem and you should contact support directly to organise a replacement as soon as possible.

In fact the battery is bloated!!! It’s only after reading the equivalent
article on fairphone site that I realised that the case didn’t fit any more
and that the back cover was popped…

So I took the battery off and waiting. I’m back to my Samsung mobile

No bloating on my battery but check out this battery life:

5hrs 50mins of useful life, of which about 2 and a half hours the phone was in my pocket with the screen off. (I was in the cinema!)


I just received my new battery…! My life has changed!

Fully charged this morning at 8:00 it’s 15:00 and I’m 72%!!! I even played Frozen for a while!!!


Even if your battery is not bloated I think you should change it… changed everything for me.

Do you think they give you a warranty ticket, if you can’t actually see that there is a manufacturing defect?

Has anyone gotten a warranty ticket with a non-bloated battery?

I don’t know, it’s worth trying but normally batteries aren’t covered by warranties.

I know there are some topics about battery problems but i didn’t find any answers in any of them. My battery goes down very quickly. It’s been going on for a few days now. This morning i got up around 08:00 am with a 100% battery, half an hour later it was 92% without using it, if i use it i can practically see the percentage drop. Now, almost 4 hours later, my FP is at 45%. Does someone know how to solve this?

Some background info:

  • It didn’t occur right after the update but i do use Kola Nut 1.8.
  • I had the 14% bug and the 15% to 1% in seconds bug but those are gone.
  • I use Juice Defender and followed some of the tips to lengthen the life of my battery.
  • My FP doesn’t always charge. Sometimes when the red light is on and the phone indicates it’s charging i see that after some hours the battery just drained. I already filled in a repair form but i’m still waiting to send my phone cause i got no replacement and the problem doesn’t always occur.

There are a lot of answers, but no solution yet! :wink: You can be sure, that if we knew, what to do, there would have been a solution posted!

For now, the best thing is to wait until the battery bloats and then request a warranty ticket from Fairphone.

This might also be interesting: Charging does not work properly.

So this is a symptom of a bloated battery? I shall wait before that happens to return it with the repair form.
