My battery health dropped to 91%. Bloody hell not even gaming

My 12 mini bought march this year, already at 93%, is it normal or not

I see well hope could be fix with software update though. Mine is drastically decreasing in the month of October.

What the .. keep dropping till it’s 90% now

I try not to check already. Gave up
I’m not even gaming. As long as my iPhone can last me through the day then I’m good

My i12 drop to 99% after 6 month of abuse.. Ngam ngam 6 month drop to 99%..

No idea..to me is fair. Maybe I am light user..? My gf 12pro already drop to 94 after 8 month abuse :/

My current concern is with my mini is battery optimization when idle/stanby mode. I notice even when on idle the battery seem to deplete a lot even without usage.

Example, charge to 97% last night at 10pm. And went to bed leaving data on etc. No WiFi connection, and when check this morning at 630 it drains to 67%.

Even my 3 year old pixel with Android 11, manage to drop 11% from 90% to 79% with the same time.

It really sucks knowing even you are not using the phone at all, the battery drains like water overnight. I'm at 91% battery health capacity at the moment.

1,800 for a used 128GB 12 Mini. Fair price?

It's a steal, though standby another RM300 for battery change down the line.

Any drop test capable cases that are on discount lately? I'm thinking of changing my Torras case.

thats really kayangan case, do you buy directly from their website for the -40% black friday?

my iphone 12 mini still ios 14.1, should upgrade to ios 15.1?

i had the worst battery in ios15.0.1, background app refresh + Waze was 100% on all the time. I thought it was a feature.
I turned it off for Waze and everything improved a lot. Back to normal.

Actually, yes I did the thing with background refresh app, but no active apps in the background at that moment. Maybe I'll try again later, just update to latest iOS version.

Anyway anyone got the apple silicon case? Ordered one on 11/11, for rM99. Any good?

Yep, got one for me. Plum, colour actually quite nice paired with my red mini. XD

I found that battery health drop significantly when charge via wireless, especially apple magnet charger, it generate a lot heat which degrade battery more faster.

i bought 12 PM in this January, now already 91%, light user , watch youtube or facebook only.
Iphone XR is greatest , now still left 96% lol

Same for me generally
I just think the 12 series battery might be of poorer quality than the previous ones on the 11 series. I remember my 11 Pro Max still at 98% battery health after 11 months. My current 11 is at 97% after 8 months

apple probably has at least 2-3 major supplier of battery cells for each phone. and each has their own sources too. I think batch to batch, supplier to supplier there should be tolerances in terms of degradation. Matter of luck. What is more important is that I find my iphone battery life stable, whereas my samsung would drop like a rock after 2 weeks (when i'm finally done installing all the apps I need). Even if the battery chemically degrade, at least the software is not doing weird stuff....except for IOS15.0.1 when i had 100% background app. Even then it was easy to fix (kill waze from background app refresh). With Android you'd be hunting wakelocks with a fine tooth comb, and then after you find the culprit you will break something else when you fix something ...
