Slow charging speed with charging control

Apps & Core Settings
1

Hi!
When I have charging control enabled in system settings to limit charging (e.g. limit to 80%) on my FP5 with iodéOS 6.3, then the phone charges only slowly:

  • up to 11W (1.2A) at 9V with 18W QC3.0 charger (= 4.2W/1A at the battery)
  • up to 7.4W (1.5A) at 4.9V with standard 2.4A charger (= 4.2W/1A at the battery)

When charging control is disabled it charges rapidly, at least with a QC charger:

  • up to 17W (1.9A) at 9V with 18W QC3.0 charger (= 12W/3A at the battery)
  • up to 7.4W (1.5A) at 4.9V with standard 2.4A charger (= 4.2W/1A at the battery)

These behaviours are the same with different 60W cables.

As soon as I turn on charging control in system settings, the charging speed drops to 4.2W (1A) at the battery. When I disable it again, the charging speed doesn’t increase again. I need to reboot to have fast charging again.

I measured charging power, current and voltage with a Chargie device and at the battery with the app Wattz.

My questions are:

  1. Is it by design that the phone charges that slowly when having charging control enabled? Is that an expected behaviour or a bug (in iodéOS)?
  2. Is there a way to fix that?
    I really would like to use charging control and be able to charge my phone at a reasonable speed.
  3. Does anybody know why the FP5 is not charging with at least 2A with a regular 2.4A charger but only charges at 1.5A?

Is there anybody else experiencing slow charging when having charging control enabled in system settings?

Same for me on my FP5. As soon as I enable charging control, the phone is only charging at around 4W. Opposed to around 20W when I disable charging control and reboot. I measured the charging speed with Wattz from Fdroid.
Its pretty annoying and makes the charging control feature useless for me.

Does this problem occur as well on other devices?

It seems to be an issue in LineageOS

Charging Control is working again since the mai update. I set it to 80% and it charges with 20W.

It got fixed in LineageOS and rolled out with iodéOS 6.4
