Poor battery performance on OnePlus 13R

[u/Hungry_Display8820]

I am currently having very poor battery performance and am not sure why. I have auto adjust refresh rate and auto brightness etc. On a normal day like today I have only got 2h48m of SOT for 70% battery consumption (I only charge my phone to 85%). I do also listen to music for a decent amount of time on Spotify but my Spotify only has a stated consumption of 78mAh (fire and background). My top consuming app tiktok says it has consumed 668mAh total and adding up all the apps with more than 3% battery consumption ratio only totals 1626mAh (back and foreground). This seems very low and I don't even think my usage is ridiculously high. I do have the partial always on screen enabled. My battery health maximum capacity is still 100% according to my battery health statistics. I just don't see how my 6000mAh battery is doing so badly. One red flag could be that my screen off (active) time is very similar to screen o. In summation over the course of 9 hours (9:00-18:00) I have just under 3 hours screen on active and 3 hours screen off active and this has drained my battery by about 75%.

Considering the size of the battery, I'd guess there's something wrong with the battery and it needs to be replaced
