Now mine hit 87%. I asked Apple again on the support email I had, they continue to say the following below. Not impressed with Apple Support.

"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. I can not setup battery replacement repair till it reaches that 80% mark."

Actually you can set up replacement battery but only if you pay for Apple Care+ - I asked for a change last year on my XS in Apple Store (because I had a problem with overnight charging from time to time, battery health was at 90%) and they changed it for me.
 
Yes, it’s absolutely terrible nowadays. Had the phone about 8 months, used to get circa 10hrs from 100%, now down to 6hrs but ‘battery health’ is 100%. Check out the awful stats. 12 pro max. Really shocking battery drain lately.

Compared to the iPhone XR the battery performance really is poor.
Yesterday forgot to charge my phone 12 pro left the house at 11am with approx 50% thought that should do until I get back in the house.
Had a couple of beers in town , sat surfing on my phone by 14.30 was in low power mode down to about 15%, just seems pretty fast to drain, my XR seemed to go on forever.

Agreed. 12pm is terrible v the XR. The latter used to last me 2 days on a full charge, don’t get a day out of the 12pm

I have AppleCare Plus but Apple refused. They said not till I hit 80%. I am at 86% currently still.

Took me 3 tries and they finally agreed to service my phone. Since your at 86% I would suggest just waiting until you hit 80%. They sent my phone out for repair, gave me a loaner. Looks like my phone will be gone for a long time maybe even longer than 5 business days.

That’s interesting. I know that AC+ is applicable to 80% or less but still it was replaced for me last summer. 🤷🏼‍♂️ Maybe try multiple stores. 😀

I was lucky as I see. They did it for me in 2 hours, I just went for lunch. 😀

Yeah I was told 1-2 hours and the battery would be replaced. My phone was flagged in the system and apple wanted to further investigate so it had to be sent out to be repaired. In a way its good since my phone will be serviced not just the battery and this may help the case for everyone. I mentioned this thread to apple.

iPhone 12 Pro late November 2020 down to 96% Battery Health. Does anyone know if this good / bad / normal ?

Seems relatively consistent with mine - 12 pro max, early December and battery health is now 98%. Not sure I take much notice of that, however, as over the past 1-2 months I’ve noticed I get ~20% less usage from the battery. The usual rubbish with Apple - battery degrading massively in time for the new phone release (nudge nudge). Price we pay for being iPhone users!

Yes. I since did some sums lol and it is performing slightly better than my previous, 3 year old phone. Obviously this assumes a consistent drop each month but a handy indicator

Thanks for replying. Appreciated
 
Launch Day 12P, typically run it from 15-20% up to mid 80's every morning on a USB-C PD charger. Battery health at 100% and I get a full 24hrs on 60% of the battery.
 
My last 12 mini suffered a big drop in battery health and was dropping weekly by 1-2% so I contacted Apple who replaced it. New one is still at 100%.

Mine has dropped again to 91% (launch day iPhone 12 Pro). I’ve never had an iPhone lose 10% in under a year, but that’s all but guaranteed this time.

I think I will have to in fall. My mini was OK for last 8 months and in the summer it starts to dropping very quickly, already 6% in about a month. I don't think it's OK and I will try to replace it. Thanks to Apple Care+ finally. 😀

I got mine on launch day in November and I am currently sitting at 94% battery health. (Literally just dropped to 94% this morning August 12th). It dropped to 99% on March 13th and to 98% on June 6th (the day before wwdc 2021). Since then, I have noticed a very rapid decline in battery health over the next month with it dropping 3% from 98% to 95% in just a little less than 2 months time (dropped from 96% to 95% on August 2nd). I have fairly conservative battery charging habits as well (i.e. charging only once a day, no deep charges, not letting it get below 40%-50%, not letting it sit on the charger over night, etc). This same time last year with my 11 pro max, I was still at 100% battery health with the same charging habits. So, I'm not entirely sure what is going on.

I think that 12 series is very bad with battery. 11 and 11 Pro were by far the best machines with battery. I’m a bit disappointed with 12 series overall. Still thinking about going back to 11 Pro (but round design and quite heavy) or from mini to 12 after 13’s models will come out.

Well the rumored ‘cheaper’ 12-series battery seems to be part of it, but 100 to 40-50% cycling is not conservative. If you really want to take of your battery, you’d be far better off letting it drop to 20%, than charging it over 80%.
 
How is deep charging better than not letting your battery down to 40-50%? Charging your phone from 50-100 only uses half a charge cycle vs letting it down to 20%. Also, the fact remains that I have been using the same charging habits for years and most recently on my 11 pro max before my 12 pro max and I was at 100% battery health at this same time last year.
