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

I have the same problems as @Spicy

"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."

To everyone who is following this thread: These tips might help you have more capacity again!

[quote=“Stefan,topic:5372,post:7”]At FP they told me that the battery has its own software inside, which sometimes needs to be reset.

  1. Use the battery up until it is below 0% (until the phone dies).
  2. Take the battery out of the phone.
  3. Plug your charger into the phone (still without battery).
  4. Insert your battery. (This will give the battery a kick)
  5. Charge your phone in one go until 100%. Do not boot.[/quote]

Edit: It works for me! :slight_smile: I get through the day easily again! :slight_smile: Edit2: You might need to follow the procedure multiple times to notice a significant improvement of the battery’s capacity.
:warning: If you have a bloated battery you should contact support immediately. A bloated battery is dangerous because it can burst!

:uk: I tried your proposal. Is it normal that the charging status didn’t start at 0%. In our case it starts at 13%.
When I removed the battery, I noticed that the middle of the battery is a little bit thicker then the boarder. Is this normal, or is the battery starting to bloat?
Best regards,

:de: Ich habe deinen Tipp mal ausprobiert. Ist es normal, das die Ladeanzeige nicht bei 0% anfängt? In unserem Fall 13%…
Bei raus nehmen der Batterie ist mir aufgefallen, das diese zur Mitte hin leicht dicker ist als am Rand. Ist das normal oder fängt sie an zu bloaten?
Danke und Gruß,

edit: Now it’s stuck at 39%

@Tuffi Hard to tell from the distance, if your battery is bloating. A good indicator is to check, if the back cover still fits on the phone. Also look at the pictures posted in the other thread about bloating batteries and see if there are similarities.

Die ist ganz bestimmt zum ‘bloaten’ angefangen!

I had a new problem yesterday :worried:

I shut down the phone with a charge of appr. 50%.
One detail: When shutting down, the screen goes black, then, after some more seconds, there is a short vibration. This went way faster yesterday, no idea if this means anything.

After a few hours, I turned the phone back on.
Directly after booting, it showed a capacity of 3%!

Additionally, all 4 entries in the quick access menu were gone! The latter happened for the 2nd time already, again directly after booting.

Are these issues related?

My battery is one with the 14% bug. But it does not look bloated in any way.

I did not try the battery reset suggested above. Will try that next.

My symptoms were similar and got a bit better now, after I had tried the battery reset. I think though, it needs multiple goes to improve the battery’s capacity.

After the incident mentioned above, the 15% bug was gone! The battery lasted considerably longer, too.


Hi, I was wondering whether others also face the following problem. My battery runs out extremely quick (although I put the screen brightness the lowest, or turn off wi-ifi and 3F), it takes approximately half a day before my battery is dead after being fully charged.

Also, the charging goes much slower than in the beginning. Turned off, it takes up to 2,5 hours; turned on, it takes 3 up to 4 hours.

Besides this, I noticed that since some weeks the ‘charging percentage’ does not seem to be correct. I.e., sometimes the lamp turns green while the charging percentage shows 82%.

I got my phone in September 2014. Two months ago I ordered a new battery & charger (perhaps the problem was linked to my old charger which I re-used), but the problem quickly began to appear again. I always try to make sure I only charge when the battery is completely dead and I always try to charge up to 100%.

Is anyone else facing this problem? (Does this problem fall under garanty?)

Thanks for the answer.


Hi @Joni: I moved your post here, as this thread already deals with the problems you describe. Please read this post and tell us, if it helps. :sunny:

So far this helping idea did not work for me. I have serious charging problems. I hope it will be fixed by the new update next week.

@Joni and @Freddy_de_Vries, did you check if your battery is bloated ? :warning:

The battery is OK. Not bloated.

Ok that’s good. :smile:
Could you tell us a bit more about your charging problems?
Also look here for a little collection of battery related problems, solutions and workarounds.

Same problems as the others… Some months ago i could use the phone for several days. Now i have to charge it every day. And when it gets to 15 % the battery load drops superfast. There might be a charger problem as well but anyway, the battery loading takes several hours… Actually one of my chargers cannot be the Problem, as my friend also uses it and does not have any problems.

I will take a look on the forum if there might be help.

Dear Stefan,

Thank you for moving the post and getting back to me with an answer. I tried the solution mentioned, but unfortunately it didn’t work. (I let the battery die, charged the phone, put the battery in after that). Unfortunately it took exactly 2.5 hours to charge fully with the phone turned off. Besides, from the appearance of 94% on, the light turned green, which I guess is not correct. I can try to do it again the next couple of days but I’m not sure if I will be able to do this - reserving 2,5 hours with an off-turned phone and letting the battery die is not very practical when not being at home.

I also checked whether the battery might be bloated, but I see no signs of this.

If anyone has other possible solutions or suggestions, these are welcome! Though I don’t adopt high standards for a smartphone - if the internet and mobile connection works, that’s fine for me - I experience this battery thing as a very naughty problem as it disturbs normal use of the phone to a great extent.

Update on my case: I didn’t have any luck with FP support. They asked me to do a number of tests (including the “kicking” the battery as described above), but none of them solved the problem.

I sent them notes and screenshots of the results, which I don’t think they’ve fully read, since I concluded my email saying that I feft this was not normal battery degradation and I got a very short response saying “It’s normal for batteries to degrade over time, but if you feel your battery is not degrading normally please let us know and we’ll replace it”.

When I repeated that the battery was behaving abnormally and described some more tests I had done, they suggested it might be my SIM-card that’s causing the problem. I highly doubt this, but I’ve ordered a new SIM-card just to be sure. However, in the meantime they’ve closed the support ticket before the new SIM even arrived, because I didn’t respond fast enough.

I must say I’m dissapointed with this level of support. To anyone else for who the solutions posted here do not work: if you value your time (and still want to support FP), I would suggest to just order a new battery from the shop. For myself, between the hardware issues and the inability to install custom operating systems, I’m on the lookout for a new smartphone. It’s a shame, since I had really hoped this one would last longer than two years.

After doing the spin test, I found out that I had a bloated battery. Reported it before the weekend and got a new one on warranty after the weekend.

I tried this reset on my FP1 (in use since jan. 2014). I’ll share my experiences because they were surprising and maybe helpful for support or battery software. Two days ago in the evening my battery warning at 15% popped up. Until now start loading it asap, this time I decided not to, following this post. Yesterday early morning the indicator was at 1% so I expected it to die in short. It didn’t. In fact, the phone worked until this morning, another 26 hours, all the time indicating 1%! Then of course I started recharging it again following this post, phone off. Sometimes I looked to see how far and how quick it was loading. At 46% I decided to turn the phone on again. After the start the indicator directly showed 82%…!
Until now the drainage pace of the battery looks normal to rather quick, but it’ll take some days to find out exactly. By the way: nothing visibly wrong with the battery.

So there is (was in my case?) obviously something wrong with the software registering the battery load.

I am wondering now: knowing about some physical characteristics of rechargeable batteries that recharging it halfway is bad for the lifetime: supposing the 15% warning has nothing to do with reality I probably recharged too soon for an unknown period of time and an unknown number of times. Could this have hurt the battery lifetime? And could this be (one of) the cause(s) of the problems with other batteries?
