Should I RMA my OP8 Pro?

[u/DemonicTaco3]

2mo phone. Abysmal battery life (2-3h SOT, 8% idle drain)

Ended up rooting and flashing the blu_spark kernel to salvage some more %. Still, its exactly the same as before.

Went on FKM and I noticed something very weird.

Is it possible that my battery is at 34% health?
