Hi @jes and welcome to the forum.
First the phone does not need one of the chargers in the ‘list’ I don’t use one.
Secondly whereas the list shows chargers that are ‘Quick charge’ and may charge the phone 1.5 hrs, Fairphone state the charge time as 3hours.
If there were no losses then the 3000mA battery could expect to be charged in approx 3 hours from a 5V supply giving 1A
Computer outputs vary but USB 2 would regularly have a 0.5A so would charge the phone in 6 hours plus.
Basically you should be able to charge the phone with most options, just slower that the ones in the ‘list’.
You don’t mention the cable, hopefully you have tried a few of those too.
Given your frustration I can see your view, but Fairphone are not causing you any trouble, it’s your expectation and Fairphone’s ‘Fairness’ that don’t equate. I agree moreso that people don’t know what will work and what will not, and although there is info on this a) it is not blatantly obvious nor clear.
Here’s the Fairphone shpeil
Charger and cable specifications
FP3/FP3+ uses a Qualcomm SoC. Therefore, you will need to ensure that your charger is compatible with Qualcomm SoC protocols.
The FP3 will charge with any charger from Qualcomm’s official list.
A charger and cable for the FP3/FP3+ must have the following specifications:
- 5 volts (5V)
- Minimum output of 1 ampere/h (1A, 1000mA). Be aware that this will have a slow charge
- Maximum output of 3 ampere/h (3A, 3000mA)
- Qualcomm Quick Charge processor compatible, version QC 3.0
- The cable must have one USB-C connector and manufactured by a USB-certified brand (if your product has no brand, it is NOT certified).
The above is not true in that
a) it does not require a QC3 compatible charger
b) the 5v 1A may be a bit slow charging but less than 1A will also work
c) the max of 3A is not the highest and the fact that a 5V supply can give more than 3A should not be a problem as only as much current (amps0 as in needed will be used, not the full 3A or above at 5v
Ok If you really can find a friend so borrow some cables and chargers, their maybe something wrong with the phone.
Try a few more options but be ready to contact support/at\fairphone …
