Battery life on Strix Scope II 96 Wireless

[Valour59]

For this keyboard, it's advertised for 90 hours with the RGB on and 1500 hours without.

What's gotten me curious is that the 90 hours number, is that with RGB at 100% or 50%?

After charging the keyboard full, I've been using it for almost 6 entire days. Let's be very generous and say I use it 10 hours a day, so that's 60 hours. Yet as of right now it's fallen to 10% battery remaining.

I have the keyboard on 80% brightness, using static purple with reactive gold (lasting roughly 0.5 sec) upon a keypress. Just curious what others have been experiencing.

Absolutely not true.  Backlight at 50%, unplugged, lasted about 3 hours.  NOT EVEN CLOSE to 90!  Unfortunately I can't get it to charge back up again!  Been stuck between 18-22% for close to a week now.  ROG must get their batteries from the same manufacturer that Apple does!  DOH!

If that's true than your keyboard clearly needs to be replaced.

So I decided to do some accurate testing. After charging the keyboard full, I set the sleep mode timer & lighting alert both to never (so the keyboard doesn't dim or turn off LEDs after some time or when on low battery), and then with my phone measured the number of hours in actual use. The color mode is static purple + reactive gold.

1) 40% brightness, 100 hours.
2) 100% brightness, 49 hours.
3) 50% brightness, 85 hours.

In all my tests I also noticed that the last 20% of the battery (ie. from 20-0%) dropped very fast relative to the first 20% (ie. from 100-80%).
