iphone 12 pro max battery health degrading

Yes that video is pretty accurate! When I first got the phone I thought it was the whole software deal & it being new. Nope, apparently for us here the 12 Pro Max just doesn’t last as long as the 11 Pro Max.

I would have thought Apple would make sure you get at least the same battery life if not more than a previous model. Hopefully the next iOS will help battery life some more. It‘s likely a hardware problem though which sucks for us.

I am very concerned with battery health as well. What’s your current %?

I’ll post the 11 pro Max health here. So 12 max is 92% & 11 max is at 96%.

Both devices were pre-ordered originally and both arrived on time on the release dates. This to me seems off. I know not a direct correlation with battery life but definitely not right. The older phone was used daily, charged/discharged constantly and many many many gaming hours on the device.

I’ll still test it out tomorrow but last I checked it outlasted the 12 max.

I bought an iPhone 12 in November

on may 18 the battery health dropped to 99%

four days later it was at 98%

even more 4 days later it was at 97%

after two weeks it’s at 96% and today I checked it’s at 95%

can someone help me please

why is it dropping so fast ?

after struggling for 2months and going to apple store for 4 times, the staff finally agreed that my batttery was defective as evidence by 92% health with 83 charge cycles. They just replaced a brand new battery for me today. I will try to check if it will work normally like other.

They asked me if am I using 3rd party charger & cable…. I wonder if that is the problem

My X,XS & 11PM I was using Apple charger & cable and my battery health was still very good after 1 year….for 12PM I’m using 3rd party cos fed up with Apple expensive cables keep breaking after few months

Do you know how hard it is to not look at it if it's right there? The temptation is unexplainable.

From the article, I have a few notes. I really don't want to charge my phone overnight. I see that literally everywhere and it's not good. And I can't only charge to 80% because I have to bring it to work and it has to last me the whole day there. So I have to charge to 100.

I really don't want the capacity to lower anymore because I know people who have had theirs for way longer than me, and they're still at 100. They don't charge overnight or let it drain below like 30%, so I followed that but looks like it's not working...

I might not get a new phone for like another 3-4 years unless of course this one breaks. So how do I stop letting the capacity go down like the other people I know? Some of them have the 12, some of them have the XR, and some have the XS Max.

I don't have iCloud backup on, it takes up a lot of room. And charging overnight with my old iPhone 7 was a bad experience, so I never wanted to do it with my iPhone 12. I'd rather unplug it right before I sleep. My friend who charged her iPhone 12 overnight had her capacity drop in like 2 days. Same with my other friend who has an iPhone 11 that's already at 85% capacity after a year and a half.

Yes, batteries are consumables, but how come other people have theirs higher than mine when we do the exact same thing? I don't understand that and I wanna keep mine like theirs.

Unless you are using the same model phone that came off the assembly line at the same time and using it in all the same places with all the same apps and doing all the same things, comparing battery usage between two different phones is meaningless.

i wish too, mine became 99% after 4 months, and then 98% 3 months after that. i'm worried that it'll drop every week now.

What you're describing is well within the normal range of 0.5-1.0% a month. There is no reason to believe it will start dropping that much every week.

i really don't know what to do.

That's an easy one to answer. You do nothing. And, more importantly, you stop checking your battery heath until your warranty is about to end (or your phone stops working properly). If it has dropped below 80% and you're under warranty, Apple will replace the battery.

I changed my battery after several visits to Genius Bar. They Also agreed that 1% drop per month was already abnormal , not to say my 1% drop per week!!

if u look back at ALL DOGCOW MOOF replies , ALL his replies were the same : 1% drop is normal . When I asked him about my 1% drop per week , he said nothing .

Just congrats me to chance of changing battery soon. We are discussing on the problem of abnormal behavior of battery . Most people are still having 100% even after 6M, at least all people around me and the 6 apple staff members whom I have chatted .

I have done. MY BATTERY WAS REPLACED at health of 92% after I gave them the data on dropping of health 2% in 2weeks!!!

THAT’s the answer to U. APPLE DECIDED THAT MINE WAS DEFECTIVE!!!!!! BTW, calibration is for 11 not 12, my friend, dont mix up, I have asked Genius Bar specifically on this. I posted my data on X, XS and 12. The 2nd photo is my monitoring on new battery.

u are using your battery in a killing way, that’s why u are at 90% in 9M

Guess what?

If it hits 80% before one year, Apple will replace it for free.

Either way, it literally makes no difference to my everyday use of the device.

I can't imagine any circumstance why I would care what my Battery Health was unless I noticed it was below the threshold/timeframe for replacement.

You don't have to agree.

If your battery is really dropping at 1% every 3-4 days, since Apple will replace batteries that fall below 80% within one year of purchase, you will be able to get a new battery for free within warranty in 45 days.

check with coconut battery, u will know .

Default capacity of 12pro is 2815mAH

87% health means 87% of the original battery capacity

=>>>2449mAH

the 100% on corner is just the full charge capacity according to the remaining capacity.

Dont mix up. Even if your health 50% (1408mAH left) it can still be charged to 100% of 1408mAH.

Just went to Genius Bar yesterday, they saw my 89% battery health, immediately did a log extraction to see the power cycle (110 cycles), replaced my phone without question. They commented that it's far below standard.

Glad they took care of you. I’m surprised they replaced the entire device instead of just the battery. I found an article published by Apple on the actual Apple website under “battery health” that does reference the 80% threshold and that same article says it’s designed to degrade to 80% after approximately 500 full charge cycles, not what most of us posting here have been experiencing.

Me too. Bought my iPhone 12 Pro at launch and it's already down to 89% capacity. That seems like a lot of drop considering the phone is not even 9 months old yet. I expect around 10% drop around the 1 year mark. At this rate, I'll be below 85% by the one year anniversary.
