I upgraded from the stock Android 14 to Android 15 with December Update that supports charging limit and bypass charging. If I enable the charging limit in the OS settings, it will also enable bypass charging and it works.

I tried using ACC v2025.12.29 and v2025.12.15 versions, acc -t reported most of the switches doesn't work and only find one switch support idle mode (/sys/devices/platform/google,charger/charge_stop_level 100 battery/capacity). This switch doesn't enable idle mode in auto mode or manually using acc -d. In Android 14, it works but not reliable and doesn't recommend using this switch.

Instead I use this switch "gcpm/constant_charge_current_max 5940000 0" for idle mode in Android 14 but in Android 15, acc -t stated it doesn't support it. In acc idle mode auto mode doesn't work but if I enable it using acc -d, it will support idle mode. But if you reconnect the USB power cable, it disable idle mode and start charging normally.

Note: I disable all power management in OS settings.

Here is the acc -t log.
