I remember this happening from time to time on jolla C, but haven’t had that yet with XIII, with same settings (4.5/always ask/90%) on current charger can’t reproduce
Same here, but problem remain when set to ‘Always ask’.
It should only ask when connecting to something else but a plain charger. At least that was the behaviour before 4.5.0.
since the update to 4.5.0.16 I have noticed, among other problems like the higher battery drain, that whenever I connect the phone to the charger, my X10 III “prepares the USB mode” and switches to MTP mode. This makes no sense as a normal charger and not a computer is connected.
I have tested it with two “dumb” chargers (one being an “old one”, and the other being a USB-C PD), a power bank (with PD), and the power supply of my laptop (one of these USB-C with PD).
I tested the chargers with the power save mode activated and deactivated as well as with the battery ageing protection being activated or deactivated.
I do not recall this happening in the 4.4 version.
Earlier on PD connections to pc were not detected at all - so that mode selection was not possible when connecting phone to laptop via usb-c cable. The new problem here is that the same “PD” power supply device type is reported both for charger and pc connections. Heuristics are used for trying to tell apart one from another - and in this case it seems that wrong conclusion is reached.
That is similar outcome, different cause (physical aspects of usb2 connectors affecting charger detection based on resistance over data lines, etc).
