Are all batteries across the 12 series phones from the same manufacturer?

no there are a range of battery suppliers/manufacturers and actually its worth doing a poll on this I think. 1) experiencing battery issues yes/no 2) battery manufacturer (coconut battery gives this info - make and date of production etc).

12 Pro Max - Owned the phone exactly 6 months today. (180 days)

Battery made by Desay Corp.
I saw another post about the other manufacturer - Sunwoda Corp.

iPhone 12 purchased October 2020. Always on 20W charger, always overnight charging and always top up to 100%.

7 months later, still 100%. I don’t care about all these so called battery saving tips.

Something is definitely wrong with the battery. Launch day iPhone 12 Pro currently at 95% battery health and 63 cycles. It's mostly on the charger and never ran all the way down or even get hot. My old iPhone 7 Plus which is a launch day phone is at 94% with 677 cycles.

You should not take this battery health measure seriously. There is no way your battery retain 94% health after 677 cycles.

Where do you get the coconut battery app. I cannot find it on App Store. Launch day blue 12 Pro Max with 88% Batt Health. Not happy.
 
The problem is the battery test Apple does is good , even if my battery is at 89% so they won’t do anything.

“No problem sir , our ****** battery works as expected “

so the big thing they advertise with magsafe is also what's killing our batteries lol that's unfortunate because i really like my belkin 3 in 1 charger with magsafe

Wireless charging isn’t new, tends to create some heat which batteries don’t like. Since everyone charges differently it’s a bit hard to just blame it on wireless charging or fast charging in general.

And yes that is one nice Belkin product.

You folks know how selection bias works? People with iPhone 12 battery problems will google it and be led to this thread. We may actually be a very small group compared to millions sold. Only Apple would know.

Agreed. This will be one of those things that enough people need to make a stink about it for Apple to formally issue a statement (or for some popular blog to pick it up). Here's the thing, we've already seen a few examples of folks with less than 90% battery health within six months of ownership. If the trend for this group continues, that means they will be at or below 80% by the one-year mark. That should cause a "fail" for their binary battery diagnosis, meaning the replacement should theoretically be free. Apple might be aware but taking a wait-and-see approach to understanding the impact on a wider scale. No reason to cause widespread panic if the group is small or those impacted don't fall under 80% until after the 1-year mark.

Who knows in the end but with my elementary level of engineering, the only change in my charging behavior has been fast chargers and wireless chargers. My screen on time and what I consume have been nearly the same for the last 5-6 years.

Yes without a issue at all ... told them that my battery is poor compared to my colleagues one who is still at 100%. Also mentioned that the phone gets very hot during charging at times .

Got the replacement up and running already. Just need UPS to pick up the old one.

When they send the replacement phone to you, did they hold your credit card the amount for the new phone and then release it after they receive the old phone? They also asked me to turn off find my iPhone and remove all the airtags in addition to hold me credit card credit for the more phone until they receive the old one.

Yeah that's right , they put a hold charge on my card. Once they receive the old one back it is released from hold. Mines all complete now. Not sure my replacement is any better on battery life as I can get it down to 40-50% in a day of moderate use.

It is brand new as far as I can tell. Im pretty particular to spotting things if they are not new.

Good. That is actually a fear IF I got a replacement as an option via Mail. (I've seen posts in the pasts with replacements of already returned devices, even phones with IMEI as "stolen") My Apple Watch battery swelled up and pushed the screen out a year ago, my replacement looked good. I throughly inspect that literally with a magnifying glass also. (Too much?? No, I don't think so!)

Swift, above got his from the Apple Store...which is what I would prefer since I have a store a few miles from me, but not the headache he had at the store from poor communication between store and Apple Support. Glad that worked out.
 
My launch day 12 PRO sat at 99% for a while and then started dropping about 1%/week for the last 7 weeks, and battery life seemed to drop. After many chats and a call with a "Senior Advisor", was told to go get the battery replaced at the Apple Store. I asked three times if they could guarantee it would be replaced if I went to the store. Was told yes, and that they would put it in the case notes.

Of course once I got to the store the "Genius" said that they could replace it... for $69. That the phone/online reps don't know how stores worked. I asked him if Apple owned the store or it was a franchise, which of course everyone knew it was an Apple Store. I told him to go ask his manager. They made me wait 20 minutes until he came back to say the manager had made a "one-time exception". The manager also passed-by the table, and in front of me told the Genius that "this is his lucky day" (referring to me), "because he had like 12 people waiting........".

Even though I got a new battery, seems like Apple Customer Service has gone down, and they are more concerned with maximizing profits!
