Battery life on the OP15 is pretty mind blowing. 5 hrs SoT over 20hrs off charge.... and still 50% left by 6pm. And that's on mobile data no WiFi and that's including 8hrs of standby time overnight, I fully charged at 10pm previous night.
I couldn't kill the battery in 24hrs even if I tried. Battery anxiety finally defeated after all these years of smartphone. Top marks OnePlus.
And it fully charges in around 40 mins. The benchmark has been set.
That's great but likely get worse over time
I had great battery life on OP13 , 7-9 SOT would get to next morning with 30-40% left
But now before bed it needs charging usually have 20% left need to check SOT since the update to oxygen 16 , had it since release battery health now at 98%
I think it's more to do with installing more stuff overtime and it's synching more stuff in the background
plus esolution support is shonky, surprisingly the older OS on my V2 did some things better, so they broke it doing updates, still it was almost half the price of the Samsung so I will cut it some slack.
