Unable to charge battery

But the charge controller in the phone will never ever pass 4.85V into the battery as this would surely kill it.

Yes I was wrong, not sure why I had that figure in my head, maybe the 3.85 and the 4 got mixed up.

Thanks for repeating that I had erred, I have amended my previous posts to that effect.

There are plenty of chargers that have less than 5V output. And if you are going to directly hook a Li-Ion battery up to it, they better do, as charging them at 5V would kill them.

And to clarify my mistake on this issue, I had overlooked the relevant issue that this related to a separate charger for batteries in general, that would be suitable for FPs

So the general statement that there are chargers with lower voltage as @mde pointed out is true.

Yet another apology for my misinterpretation of a query I was a bit too quick to try and answer. Oops! Again

Just a brief message to say I received the the Ansmann universal charger Powerline Vario X an hour ago. Initial impression: Its contact pins seem to reach deep enough into the contact canyons both of the FP3 battery as well as the FP4 battery to trigger the Powerline’s charging display (no vertical battery position needed to fit the contact pins). I will create a standalone topic once I can provide more experience with it. Update 06/02/2022. Find the topic here:

External universal chargers for Fairphone batteries

Pre-sermon: What for?

Those who have followed Fairphone for a long time know that the charging port of a Fairphone is – very much like in other smartphones – a neuralgic point. When it doesn’t work, the whole device is soon becoming unusable until it is fixed. We have seen the spare part becoming unavailable and available time and again, sometimes after 1-2 weeks, but more than once, it took months. The FP2 bottom module that includes the charging port was the first spare part that Fairphone had …
