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

But remember that a battery is not getting better from just lying around.
For storing, often 5-10°C and 60-80% charge level is recommend and using it from time to time (between 20-80%)

Maybe a better way is to swap your both batteries each 1-2 months to use it the same way and dont use the first for 1 year and after this notic the 2nd is not usable anymore due too its long rest (without seeing new electrons).

tnx, that’s interesting.
I was told when I got it to leave it and that the wasting would only start once it is used.

Are you referring to a battery which NEVER was used once? Who told you (FP?)? Than MAYBE here is a difference.

But I was referring to batteries which at least have been used once or twice. And to avoid the degradation of the inner electrodes a moderate usage is recommend (once a month for one charging cylce 80-20-80% should be enough).

It is the same thing which a lot of battery guides telling you for laptop-Li-Ion-batteries…
(At the moment I have no time to look for some links…sorry)

My phone is now fully charged… but I did that at the office…when you say “connector” your mean on the phone?

Yes :slight_smile: , as I said, it’s a new battery. And the tipp came from Fairphone.

  • Where is the difference of “at home” and “at office” in your case? Different charger?
  • I mean the connector at the phone itself (as you can see at the pic in the other thread). But basically it could also happen to the plug of the charger itself.
  • did you already try the “Battery-Software Reset/Recalibration”? But that would only make sense, if you considered the possibility fo the “dusty connector”, which then should be cleaned before!

Cheers, Robert

Yes different charger… by the way yesterday everything went fine… it’s the part I don’t understand with this phone: it does weird stuff and then back to normal…

Also a sign of a dying battery. I’ve had all the symptoms.
Be careful: I’m pretty sure your battery is bloating, even if you don’t see it yet.

Seriously?! Again?!!

What’s wrong with those batteries? Or is it the phone?

And apart from buying another one is there anything I can do to prevent this?

Actually, I was told by FP that a battery can die after 1,5 to 2 years (shorter lifespan for smartphone batteries) without ever bloating. Mine shows the same symptoms, so I will use it for a while more, but have a new unused battery ready for the official battery end of number 1.

My Nokia N900 battery is still very healthy after 5 years of use (and I treated it very bad!).
I tend to suppose there is some problem with the design and/or hardware quality for the FP1’s batteries and I hope there will be an enhancement in FP2’s ones!

But I have already changed it once this year! I agree with DjDas there’s something seriously wrong…

It would be good to hear from FP about this. I’d have thought 2 years is also not a very long live-span, but they said it’s normal for smartphones, different from the old mobiles.

I’d expect the power draw from a modern smartphone to be higher, especially when running demanding applications. At the same time, the temperature will also be higher. Both are things that challenge the battery more, and make the battery behave differently from those in old mobiles. Although, the N900 may be more like a smartphone in terms of battery use. I’ve also realised that over the past two years I’ve charged my FP1 battery more times than I charged my previous phone in its entire 8 year life span (during which I replaced the battery once due to degraded performance, and I haven’t replaced my FP1 battery).

Note that the temperature should, however, be guarded against excess by software monitoring of battery temperature (just search the web for battery temperature too high). I’m surprised that nobody has posted about receiving a too hot notification other than when the ambient temperature is too cold. I sure hope there isn’t a bug in the monitoring software and people are cooking their batteries during periods of heavy battery use.
I’m not ruling out that there is a bad batch of batteries, or that the design of the charge controller is somehow flawed, or that the design of the FP1 itself makes the battery more susceptible to thermal or physical shock.

We’ve asked about failure rates in the topic here, but it seems unlikely there will be an answer soon.

People should have noticed that their battery would get abnormally hot. My current phone (not FP) has a temperature sensor inside but I was never advised to turn it off. Especially lately I notice how my battery gets warm while I use it so I turn it off and take the battery out for a couple minutes.
Somebody on this mighty planet should have noticed if the battery was being cooked regularly.

I’m having the same issue reported by many users here. Charging does not work reliably. It’s not due to a defect cable or battery. Notably, the problems only appeared after the software update to 1.8.7.

You already tried out in this order

  • battery spin test
  • cleaning USB connector
  • reset battery software

all described here? Cheers, Robert

Very interesting… straight after I updated to 1.8.5 the battery life of my phone (FP1U) dropped dramatically. I reported it to support at the time. It wasn’t bloated.

For some reason, the battery life got better after two months, by itself.

And now it’s bloated…

I have it too a strange problem with my battery.

Often the morning when I switch on the phone the battery from 50-60% of night drop down to 10-20% at the morning.
It’s a strange issue that I’ve learned to prevent by switch off my phone during the day to see the “really” level of charge of battery.

I tried twice to force the software reset (from 0% to 100% as explained here) but it didn’t resolve.
I tried also spin test and I can see that can rotate but it doesn’t look so much swollen and it fit quite well in the battery compartment…

Everything you describe fits with a failing battery. The battery firmware reset will not help.

Doesn’t mean that the battery isn’t dying. Give it a couple of weeks and it likely won’t fit. I recommend contacting support for a warranty replacement now, rather then waiting for damage to the phone.
