Is it just me or after one ui 9.0 your battery health took a massive drop because mine went from 100% battery health down to 90% and its only done 64 full charges.

How old is the device. Where did you get it. Not even two year old battery would suffer such a drop. Try diagnostics via Samsung members app

No don't worry, your device should still be okay from what i see anyway. Your battery capacity didn't drop your phone is just telling you that battery protection is currently active and is capping your battery at 90% to protect itself!

your battery life says its good which i think means it still has a good amount of its original battery left. If you are concerned about your battry you can ask bixby to see whats draining your battery and fix it. Or obviously take it to Samsung to fix it themselves but thats extreme

It's not the update it's a battery protector on it and it will only charge up to 85 or 90 %percent to protect the battery and you can charge it in the settings in battery settings because my phone won't charge over 85% to protect my phone battery

You should see the discharge rate and how much the battery is self-discharging, you should download AccuBattery or Phone Temperature and check the discharge levels; if it is discharging more than usual, you should have it inspected by a Samsung authorized center.

Many users, including me, have seen a drop in the battery healt after the one ui9 update. This looks like a bug. After the one ui9 the battery is recalibrated and the old stats are deleted. Therefore the new reading in battery healt is a result of new readings, but it appears to be inaccurate.

I went from 100% on one ui 8.5 with 209 cycles to first 99% to 97% only few days later after updating to one ui 9.0. This is a fix samsung has to patch. Since this is a widespread issue it proofs that this is a bug in ome ui 9.0. Let's hope Samsung push out a fix in a upcoming update. It's not possible for the battery to degrade so fast with such a low charging cycle. It's rated to 2000+ cycles. So if this was actually the % we are seeing, then the battery wouldn't last that many cycles by a long shot.

Agreed. I'm not updating until this bug is fixed. Very poor software QA by Samsung.
