Battery percentage drops fast to 50%, then slow

[mimre25]

Describe the bug
After charging my Raise 2 to 100%, both halves quickly drop down to 50% (within a day).
After that, it takes another week to go down to 0%.

To Reproduce
Steps to reproduce the behavior:

1. Charge Raise 2 to 100%
2. Use for one day
3. See 50%
4. Use for another week
5. See 0%

Expected behavior
I would expect the battery percentage to drop more linearly (I don't know whether the battery drains linearly or not - hardware isn't my thing much 😅 ).

I'm totally ok with the battery not draining fully linear, but right now it seems a bit odd to go down to 50% within a day (or even few hours), and then take 5+ times as long to drain fully to 0.

Desktop (please complete the following information):

• OS: Arch
• Bazecor Version: 1.6.1-3

Additional context
Full timeline of my experiment:

• 2024-12-27: Charging both halves from 0% to 100%
• 2024-12-28: Unplug chargers before use. At the end of the day, see 50% for each half.
• 2024-12-29: Normal use
• 2024-12-30: Normal use
• 2024-12-31: No use
• 2025-01-01: No use
• 2025-01-02: Normal use
• 2025-01-03: Left half @ 20%, Right half @ 0%

I can monitor this quite easily, as I've added the battery percentages to my status bar (see #941).
So I always see something like

when using the Raise 2.

Note:
I'm not sure if this is the correct repo to report this issue, as I think it might have something to do with the firmware, but I wasn't sure which repo is the right one for the firmware.

Thank you @mimre25

Yes, we've noticed this. We've changed the battery management chip for the Raise 2 compared to the Defy, and we still need to adjust the algorithm that translates the battery readings.

We're on it 😊
