I did a battery recalibration test on my 2nd month. Basically you just fully drain your battery from 100%-0% and theoretically, your battery will perform not like new, but just at its best again. Also it's said to keep the battery healthy if you drain it occasionally but whatever.
Anyway, X-mode on,100% brightness, 144hz, WiFi on, location on, flashlight on and volume at 10%.
I let 11 hrs of Mr. Bean play on YT fullscreen while i slept, hence the 10% volume. The flashlight auto-closed at 15% but the total SOT I got was around 11 hrs. I haven't done another recalibration yet because i feel like the battery hasn't changed much at all.
I don't bother myself with charging precautions since slow charging's broken anyway but i charge at least twice a day from 50%-85% and no performance decline yet. I use bypass charging for PUBG since 90fps drains twice as fast.
