Hi!
Does this mean half my battery is dead and I got to return my phone?
It sure feels like it's half battery my Rog phone 2 lasts more.
Thanks!

I noticed the same. I think this is because every battery has its own sensor and AccuBattery reads only one, so that's why it is divided by half. Despite that, my battery is completly fine and it last like 5300 mAh battery.
P.s. I set battery capacity to 2885 in app, because one battery is rated for 2885 mAh, 3000 is just marketing.
ROG 3 battery should last longer but not as much, like ~13% more.
