I have tested it now. Usual press to turn it on = 1 second, longer than usual when plugged in = 4 seconds.
That is fine and expected behaviour.
To make things clear:
- If the phone is off, a short press (1 second) will boot the phone.
- If the phone is charging, a short press (1 second) will display the charging animation and a long press (3~4 seconds) will boot the phone.

Hi,
I just submitted an issue with my Fairphone 2 and charging. (See ticket #98477)
The battery was completely drained while it was attached to the charger. This happened after the 1.2.8 update.
The battery is completely drained and I can’t start my FP2.
I added a USB current measurement device to check if it’s charging.
It seems that the charger delivers 0.91 A while the phone is completely off.
When it boots to battery charging mode, (with the battery animation) no current is drawn.
Also no LED is on at that moment.
After a while the phone spontaneously boots or just goes back to completely off, with red blinking LED.
After a while the whole process repeats.
Sometimes Android tries to start and wants to optimize applications.
After optimizing 50 apps, it just goes back to the completely off state (with red blinking LED)
The charger, cable and FP2 used to work OK.
best regards,
Jelle
I have the exact same problem as @jhaand. I just “charged” my phone the entire night and it is still completely drained. I did not use any other chargers or did anything differently than I normally would.
I am fairly confident that we can confirm HTC’s TC E250 (5V, 1A) as being problematic with the FP2, at least at low battery charge levels (with both the former and the latest software).
We have a total of three of them in our household and we’ve tested them all (with several different cables, none of which seemed to have made any difference one way or the other), and they all caused unstable charging until the battery went beyond a certain charge level. Beyond a certain level, charging stabilizes, but is still slow (~6 hours to fully charge from ~10%, for all three TC E250s).
The ASUS ADP-188W A (5V, 2A) which came with my TF201 works just fine at any charge level and charges much faster.
My assumption would be that the TC E250 is unable to provide a stable enough current for the FP2 at low charge levels, but I don’t have the necessary equipment to make any measurements. It did manage to charge the phone, but not in a satisfactory way.
Jelle, and Emma,
What happens if you use a more powerful charging facility - such as one delivering 1.5A or 2A?
Please remove the battery for at least 30 minutes and try again to charge the phone with a powerful charger to see if it makes a difference. If possible, let the phone charge completely (and then some more) before booting it.
I do agree with Dunsay in that less powerful charging facilities and not stable enough ones might not work as expected, especially when the battery charge is (very) low.
Jelle, you said your charger+cable were working fine before but did you ever reach such a battery state (depleted)?
i have to correct myself: random reboots happen now more often, eg when starting a call while dialing.
not every cable is accepted, but a big relief, nonetheless.
lets see…
i found the solution in a german thread: for the reboots after starting a call: its the setting 4g preferred
I’m somewhat relieved to read all this since I started to think that it’s me doing something wrong. I ran around trying different cables, chargers and power outlets. For the last 10 hours my phone seems to be in a red light - booting screen - black screen loop. Maybe the battery was this time even emptier than before. The problem before was that the charging took so long that it never really finished until I had to unplug the phone to go somewhere. Even charging over night didn’t fill it up.
What’s fairphone’s response, does anyone know? I’d like to fill out the form but I don’t know most of the answers since my phone doesn’t turn on. So no idea how to look things up.
Would be happy to hear about a solution.
You can still write a normal support request and telling what you tried and what not worked. But response time could be a couple of days!
You had this problem from beginning?
Up to now the response has been to get a more powerful charger.
see: Charging the FP2 / cable problems
I might try this when I have the time to order a working one this weekend.
Thank you for specifying a reliable, known brand and available charger.
Just ordered a 2 port Anker 20 W charger.
After having the FP2 for more than three months: I noticed that the Anker charger is charging the FP2 much faster than the PC or laptop.

Yes, I did that. The battery charged super slow but this ongoing loop issue is new.
Which not neccassarily means that much, as PC and Laptop are limite do 0.5A, normal USB chargers provide already 1A, and Anker maybe 2A (from which it is still questionable, if FP2 really can profit of more than 1A…)
But if you noticed already before that it did not work good (how long for a full charge?), it is possible that it is just the same problem, only in a completely-drain-mode…It’s not nice for you, I am aware of.
And after trying that much of cable/charger combination (I think also PC/Notebook?!), you did not find ANY good working combination (where it charges in 1-2h from 0-100%, as it should be)?
You tried this already witht the most promising combination?
Actually, it does profit from 2A. My powerbank has two output sockets, 1A and 2A and the difference in charging speed is really noticeable, especially, when I’m using my FP2 heavily (e.g. reading this forum with mobile data and the screen at full brightness) while charging.

OK. Do you think that time is also the half? How long does it take from 0-100% or 20-80%?
Well, just to add my experience: I’m having the same charging problems.
Some chargers work, some cables work, some USB-ports work - but most combinations do not work.
Having three chargers, about five cables and more than 15 different USB-ports at different computers, “scientifically” finding out which combinations do (not) work takes “slightly” more time than I’m willing to spend.
(Also uprading to OS version 1.2.8 did not change this behavior.)
Althought I support the idea behind FP, this (along with some other bugs) is quite dissapointing.
Especially because I get the impression, that the FP-Team isn’t very hard working to resolve this issue concerning quite a lot of FP users (or am I missing something?).

I don’t have these issues, so please consider the following:
- for charging, use a DATA-Cable (Plug it into your PC and see, if data transfer is possible)
- the length and quality of the cable (-> resistance) has an impact on the charging speed.
- Charging with PC is always slow, as you can only draw 500mA from a Port.
- Use a good charger (e.g. from Anker) and no cheap no-name china ones

Hi retsfip,
thanks for your comments.
It’s clear that all what you mentioned has an influence on chrging.
The point is: I never hab any problems charging a quite decent variety of phones - the FP2 ist the only one showing this problem.
And - regarding this topic - I’m not the only one …

Continuing the discussion from Unfairphone does not charge:
Yes your correct I am mad having bought one tough phone I bought a 2nd duff phone. And when I point out the problems a moderator closes the topic down my phone will not charge from a computer and I cannot find any way of making it do so despite using the same cable I use with a phone charger.
