FP3 Slow Charging

You do not have to, just plug out and in the cable several times until charging is fast. It seems to be a bottom module issue:

I did some additional testing.
One way of being able to compare some stuff is using the app Ampere. It does a mesurement of the charging.
Funny thing; the Samsung amd the fp3 both get about 470ma out of a usb splitter.
I connect a single usb charger;
The fp3 doesn’t start charging while the samsung goes over 1000ma

I’m gonna contact support with this measurement. Hope it is fixable, preffeably without the need to sent the phone.

It is a hardware problem, another user had the same issue and received a new bottom module from Fairphone, and that solved the problem. Just make them aware of the linked thread above, this should keep them focused on the troubleshooting process…

Issue is fixed through the service departement.
The phone was shiped to France and the bottom module was replaced.
All chargers now work again properly. Even the once that first didn’t charge at all.

This is for me again a thing where the ability to fix modules is a reall plus, next to the good service by Fairphone.

In my particular case, the peoblem turned out to be the socket converter I was using (in combination with a USB-to-USB-C cable).

Those white thingies with a USB opening that you plug into the mains.

Turns out some of them work fine for an iPhone, but if you plug in a FP3, the charging will be extremely slow, sometimes even de-charging.

We own two very similar ones. The slightly larger one works with FP3, the slightly smaller other one doesn’t. Go figure. Turns out I switched them.

Usually just called “charger”.

Just a note to other readers to avoid confusion: the cable shown in wytzeschouten’s post above is not a standard USB cable. It’s a cable designed for charging iPhones and iPads and has a USB-A plug at one end, on the right in the photo, to go into the charger and a Lightning plug at the other, left, which fits sockets on the Apple devices. Don’t get the idea you could use this to charge a FP without an adapter of some sort.

I have the exact same problem. Had my Fairphone for about a year and it always charged normally until a month or so ago. Now it charges extremely slowly. I have not changed the charger, and I have tried all the unplugging and replugging and what not that is suggested in the replies above. Do I really have to send it in for repair and thus be without my phone for weeks? Not very practical in these times when you need digital covid passes just about everywhere.

Hi ziwa.Welcome to the forum

I imagine you’ve read other topics that mention alternate cables and chargers etc.

And those that indicate a cleaning of module contacts and resetting them may help

It can be dirty USB port on the phone which isn’t that easy to clean.

The software options are few, a safe mode start and keep that for a day two to see if that may help, even the factory reset.

If you don’t want to try any of the above you’d best contact Fairphone as soon as, as they will have questions so it may take a week before the ask you to send it.

Have you tried contacting a #fairphoneangel near you.

By the way lately my phone is ‘charging slowly’ maybe 20% in an hour if

I just bought a used FP3 with the same problem. I already own a FP3 that charges quickly.
So I used the same charger and the same cable - the FP3 only charges slowly
Today I installed the bottom module from my working FP3 to see if it’s the bottom module-> no change still only slow charging.
I have 3 batteries. They are fine, because when I use them with my working FP3 then it charges quickly
So it can’t neither be the bottom module nor the battery nor the charger nor the cable.

yes, I did. I have two FP3 and I installed the working bottom module from the other phone but it still charges slowly

The power chip is on the core module. If the phone is under warranty, better get in touch with support at fairphone .

I have the same problem.
Does it help buying a new cable for charging?

Welcome to the Fairphone community.

As described here in this thread, it might help. But the root cause can also be some debris in the bottom module, a broken connector or a dying charger. So there is no guaranty, that changing the cable will help for sure.

Hi there,

I need help. Since two days now my FP3+ is not charging correctly anymore. It was connected to the cable all night and is only charged by 33%. That’s pretty annoying. What’s wrong here? Any help is highly appreciated!

Kind regards

Hi

Slow charging is a consequence of the charger and phone not communicating properly.

There can be a number of reasons and the above posts and other topics may help you decide how to proceed.

The most common causes are dirty port on the phone, not easy to see or clean.

Will find a link

The second possibility is the cable. Fully compliant USB C cables are diagonally symmetrical so that it ‘shouldn’t’ matter which way that end is inserted.
If the wiring or contacts are damaged on one ‘side’ then it will only charge in one direction or if the contacts on one side are tarnished then the charge rate may be reduced. You can re-orientate the cable to see. If it’s the same then it should be fine. Test the cable else where and try a new cable to confirm.

If you can asses the charger and cable can quick charge other devices, we are back to the phone.
The port may be dirty, so clean or at least try a couple of times
The bottom module may not be seated well or it’s contacts may be tarnished. You can remove the bottom module, check, clean and reassemble. Whilst you do that check for a red or white square. If it is not pink or red you may still have a valid warranty.

If all the above do not work you can buy a bottom module and see if that is the cause, if you use the warranty note your phone will be wiped so save any data before you send it off.

Here is a link to a post with image of the ‘red’ square and the successful effort to clean

All the best

I’ve owned my Fairphone 3 for around 2 and a half years. about six months ago I had this slow charging problem and I went through all the remedies that have been explained above. In the end I took the advice of someone from a different thread to update the phone while the battery is charging, and this did the trick. I had no problems until this month. I used a new charging cable which was faulty and actually damaged the USB port in the phone, so I had to buy a new lower module. This has been working fine for about 2 weeks but suddenly has started this old slow charging problem again. I think all my system updates are installed so I don’t know what I’m going to do next!

Hi Paolinho,
Cable plugs (both ends) and USB sockets can get dirty very quickly. Make sure these are all clean, including at the charger end.
If you’re still having problems, you might take your phone to a local repair shop (which doesn’t need to be a Fairphone specialist) who would be able to check the charger and cable, and maybe try other chargers and cables.
You might also get in touch with a local #fairphoneangel if there’s one in your area.

Has anyone found a solution for this charging issue? I was reading other threads but didn´t find a clear solution.
It seems that I have the same issue with my FP3+. Some cables only charge at all one way around (cables that are USB-C to USB-C). Yesterday my cable that has been charging just well for months only charged slow charging. So I used my laptop´s USB-C to USB-C cable. It charged normally. Today the same exact laptop cable charges slow.
I´m beginning to think I have to check if the USB-port in the phone is dirty, as this laptop cable started to charge normally after a few connects and disconnects.
