Hello,
I am experiencing a similar problem as listed above.
As of yesterday, my phone will barely charge. 1-2% per hour, and is down at 20% battery.
When I connect it to a USB power charger, it only draws 0.06A, and charges very slowly. Using the exact same cable and charger, another FP3 can draw 1.45A, so it is not the cable and charger. I have also swapped the battery with another device, and this make no change to either device, so I do not believe it is the battery.
Based on the suggestion above, I restarted and cycled the airplane mode a few times, and this seems to have fixed the problem (the phone is able to draw 1.4A, and is charging at regular speed.) However, sometimes the airplane mode cycle works, and sometimes it doesn’t.
This seems to not be a one-off problem
I tried updating software to the latest version, and the airplane mode trick seems to have stopped working, so it is now constantly stuck in Slow Charge mode.
To me, it seems that the phone is getting stuck in slow charging mode, when it switches off the Qualcom Quick Charge: FP3 Slow Charging - #6 by teezeh
Questions
- With the restart and cycle of airplane mode, is this likely to be a software issue, or a hardware issue?
- Is the charging circuit in the “bottom module” of the FP3 - Would there be any value in purchasing and swapping out this module?
Any help or suggestions welcome
