Describe the Bug

Некорректный уровень заряда батареи. Заряд падает со 100 до 82, далее устройство выключается.
Устройство уже несколько раз разряжалось полностью, так что это не проблема каллибровки. Проблема была так же на 1.5.0.
Батареи хватает на неделю.

Incorrect battery charge level. The charge drops from 100 to 82, then the device shuts down. The device has been fully discharged several times already, so this is not a calibration issue. The problem also occurred on 1.5.0.
The battery lasts for a week.

Steps to Reproduce

daily use of the device

Expected Behavior

Correctly reducing the charge level from 100 to 0.

So in the current implementation, the firmware is just reading out what the battery's chip is emitting. Crossink (and Crosspoint) is literally not doing any smoothing or clamping (which could introduce it's own issues). So if you're seeing 100 -> 87 -> dead, it's because the chip is telling Crossink that's what it's charge level is.

Crossink could try to smooth this, but it will still not be perfect since the chip is providing faulty data to start with. For your situation, it would show 100 -> 87 and then a rapid drop to 0 (instead of just dying), which you'd probably also open an issue for haha so... no real win in this situation.

@uxjulia Thank you for the quick response. It seemed that the problem wasn’t so obvious in earlier versions of CrossInk. In any case, thank you for your great work.

So is this something we should try to claim as warranty to seller or just normal operation for this kit?
