Quite an interesting observation.
There seem to have been some modifications to the specs.
This eco charging-mode like the FM-radio, that initially was announced are really sad to see gone.
I really wish, that FP would be clear and open when dropping such features of the phone.
Even more so, since the homepages of some resellers don’t seem to reflect those new developments.
Vireo states in the features list:
Qualcomm Quick Charge support: No
while the FP-support page (already mentioned above) features a parapgraph:
The FP3 supports Quick Charge. This means you can supply your battery with new energy quicker than before using a Quick Charge compliant USB Type-C cable. For quick charging, you will need charging equipment that enables this. It must be QC 3.0 with a maximum output of 3 Ampere and must be a USB certified brand.
Plus they sell the USB-charger stating this:
Fairphone 3 supports Qualcomm Quick Charge 3.0 to allow you to get the most out of your device.
Maybe you could help to lift some of the fog around the FP3 feature list and make a final statement of what is and is not included as a blogpost or on the specs page.
Some explanation regarding changes to the feature list would be a most welcome extra.
Plus: FP should really check the homepages of the resellers for accuracy, since they happened to change the features list.
