Charging Problems: Switching between charging and not charging

Hello!
I got my new FP3 yesterday, and at first I was very happy. But then I tried to charge it, and this did not work at all. I had same issues as described in this post concerning FP2:


Now I am quite disapointed - if they had same problems already with FP2, why does it now happen again? I already tried different charging devices, and this did not help.
Of course it is a good idea for the environment to not deliver a USB charger together with the phone - but if then the charging is so special that the people have problems to find a charger that fits… That is very ennoying!

Every problem can happen with every device. This was never “a problem of the FP2” but a problem with a specific device.

Please elaborate. Did you try different USB data cables, plugs & sockets? How many?

It’s not special. You just need a good charger with a good data cable.

I’d suggest trying a new cable and checking the output of the chargers you’re using.

It may be that the cable or charger or combination doesn’t produce enough, consistent, charge for the phone.
I had a similar problem with an old charger I had, it was rated at 1A.
In much the same way as yours, it’d switch between charging and not. The phone doesn’t have trouble with the QC3 compatible charger I have from a previous phone.

I found a different 1A charger (Chromecast) and tried that instead, now it charges flawlessly.

Hello, I’m facing to a bug charging…
THe carger is ok…
The FP3 charge only if is powered on, this is for me new since 2 weeks, before no problem to charge on mobile phone switched off.

When is charge from switched off… it’s start as normal, prompt the fairphone logo on black background, then stay on a black screen with full of display light.
When It touch the screeen, it show my fairphone is charging (picture with battery and cable) and it restart again on charging mode… and it’s looks (only if I retouch the screen).
A night charge in this condition bring me 10-12% charge max.
Some ideas?

Thanks

Hi you could upload a static image or two rather than a video.

The charger and cable are most often the issue and can have a dramatic effect on charging from 1.5hours with IF 3 compliant charger and cable to 6 hours with just one compliant.

How old is the phone? If dirt gets in the USB port that can slow charging down. Unlike my 5 year old samsung the FP sends signals to the cable to see what it can handle, then depending upon response will communicate with the charger.

Some chargers have a fixed charger/cable and if IF3 compliant only the charger is tested.

I.e. to get the optimal charge rate, if the phone is OK then both the charger and cable have to be IF compliant.
