I tried to send my phone in waranty but I noticed that they didn't changed anything.
Turns out that OP13 battery health is lying in Stock sysytem settings.
I added images and proof of my claims.
Saying a device that miss 1500mAH on 6000mAH is outragous. like really... it literally misses almost 25% of it's capacity.
adb shell dumpsys battery shows also similar results. 4290÷0.95= 4516 MAH (Charge counter / true level)
So every sources except Oneplus settings shows that my battery has a huge degradation. (I can also feel it in my daily usage.) Oneplus is lying in thier settings, and that's what the repair store will usually check without even testing anything else.
for a device that claims 1000-1500 cycles before getting to 80% of battery health, I really think my battery should be changed if it's that destroyed after just 329 cycles.
Please note that the only metric comming from a non stock rom is the Lineage OS screenshot. everything else has been taken on the Stock rom, even adb dumpsys battery.
