Note 10+ battery drains super fast after latest update

[DrTareq]

I updated mobile today. I wish i didn't! Battery seems to be draining 1% every 3 minutes! That's crazy. Even with charger on, it gets super hot.! My Note 10+ is less than 1.5 year old.. In mint condition.. Any suggestions??

Hi, try to clear your cache partition, update your apps from Google store and play store

[MohammedSijah]

Being hot, soon after the update is normal. It may show some battery drain too. Please wait 2-3 days so that it gets adapted. Anyway please wipe your cache partition.

If nothing solves, perform a battery calibration.
(Drain your battery to zero. Again turn ON and drain fully. Now charge it to straight 100% without turning ON (slow charging preferred) Remove any phone case if any, to prevent heating while charging. )

Is that method tried and guaranteed not to harm the battery?

[MohammedSijah]

I can just guarantee that it's tried and it solves. I myself had done it too. (Eg: https://r2.community.samsung.com/t5/Tablets/When-my-tab-is-in-93-it-js-showing-full-charge/td-p/9041...)
But regarding the battery health, I'm not an expert for that. Draining battery beyond 30-20 is never preferred. I never do it. But this usually applies to continuous and habitual usages and in a long run.
If we drain it just for once and it is for a purpose, I would say no issues.
We take drugs, and everything have the side effects😊.

Try replacing the battery, if it's health has dropped as that's also one of the reason for battery dropping like that, or try putting unused apps to sleep
