Incorrect battery levels for SteelSeries Arctis Nova 7 Wireless

[ProLejka]

Description

Hello. I have weird bug. When I check battery levels on my Arctis Nova 7 there seems to be only 3 states 100% 50% and 5%. I cross checked with app in Windows and it looks like 100% is 100%. But then it gets weird.
In Linux headsetcontrol reports 50% when there is battery in official app between 100% and 50%.
And after that it gets weirder because if it's under 50% (in official app) it just reports 5% in Linux. You can even see it on led on headphones that it reports for example 50% - orange led. If it's really 5% it would be red. It's very confusing because now I still have to check led on headphones to see if I have to charge them.

@ProLejka did you build headsetcontrol by yourself?

Because I edited Artic Nova 7 Wireless code a few months ago and putted wrong numbers to for the different battery levels by following user manual, and then rolled back original code a few days ago because older one was more inline with Steelseries Engine advertised battery level.

I also observerd that hadphones led shows completely different levels than the values of Steelseries Engine.

If you anlyze headphones packets they follow Steelseries Engine levels:

Percentage	Packet Code
100	04
75	03
50	02
25	01
0 (Never reached)	00 (Probably)

While instead into headphones manual the reported levels are:

Percentage	Color
100-50	Green
49-15	Yellow
14-5	Red
4-1	Red Fast Blink

Ah... I did and I probably hit the time when it was like that HeadsetControl (3.0.0-17-gb4d0614)
Now on HeadsetControl (3.0.0-23-gc0c9b50) it looks fine. Sorry in future I'll remeber to pull first.
Thank you.

No worries, it was also my fault to edit code that was already correct
