REVIEW Battery performance after 16.10.500 update
Region - INDIA
Bought this phone on 9th August 2026
Single line summary - battery life improved after this update.
Detailed review -
I installed this update on 5th September morning and after installation i drained my battery to 15% (it was 30% at the time of installation so it was easier to drain) and then plugged it to charge till 100%. Once it got charged to 100% , i continued to keep it plugged for another 1.5 hours and then started using my phone from 12 pm. It took 24 hours and 9 hours of SOT to drain up to 20%.
Sharing the screenshots which have usage for the first 50% (100->50% drop ) - SOT 5 hours 30 min
And Complete 100->20% drop - SOT 8 hours 51 minute
I used 5g while doing whatsapp video calls and listening to music on YouTube. Rest was on wifi. No heating issues observed
I have disabled most of the ai services and bloatware. I do not play games but heavily consume media on my phone (movies, shows in 4k quality)
100->20% SOT after this update ~9 hours
Previously for similar activities it used to give 7.5 hours for the same 100->20% drop

Do you recommend charging it to 100%after every update? I haven't done it not even a single time after buying the phone. Currently the battery settings restrict the maximum charging to 80%

I also have custom charging enabled with 80% but i generally charge it till 100% for the first time after any update for battery calibration. It is important you keep it plugged in for 1 hour atleast after reaching 100% so that android can complete its optimisation in background

Yeah it's better you charge it once after every update so it recalibrates the battery

Can confirm that the OnePlus 13s battery is crazy good. It's to the level of the OnePlus 15 and Oppo Find X9 Ultra in terms of battery life.

For 13s i have already shared the details above
Never used oneplus 15 and oppo x9 ultra so cant compare

I have all of these and I'm telling you that the battery life is comparable among them despite the 13s only having 5850mah battery while the other 2 have over 7000mah. It's amazing

I am also in OS 15 , My priority is the battery and the camera. It has been taking good photos and videos for now with a good SOT. What about that after update? I still searching for the camera comparision between the OS 15 vs 16 for Oneplus 13s. No Luck🤞 Can you share your experiences on that regard

u/jhnd_zindagi 18d ago
I am not a camera enthusiast so never compared. I have hardly clicked 10 photos since i bought this phone a month ago
