Capacity improvement for under $20
iPhone 12 Pro Max Battery and tool kit 5600mAh. I replaced this battery for the first time in this phone. The original battery health was at 72% when I replaced. It’s a notable difference in capacity and use time. I’ve done a few of these batteries in older iPhones; SE gen 1, SE Gen 2, X but this is a tougher swap. A strait edge razor blade is needed to separate the glass. The kit came with everything needed. Also included was a screw mat that I’d not had in other battery “kits” and it was helpful. The phone gives the “Not Genuine Part” at start-up and the heath data is supposedly inaccurate. What I know is that I used to use 300-400% of capacity a day, now it’s closer to 100%. You have to solder on a used (or new Apple) battery control module to avoid the above. Delivered the next day. Less than $20 for a phone refresh was worth it. I don’t believe Wouldn’t recommend to beginners.

Battery failure in 4 months
I installed this battery at the end of September and swelled up/ failed by January, no longer holding charge and cracked the screen as well. I do not recommend buying this one.

Works as intended
It works , holds charge but iPhone does not recognize as an oem battery so you can’t check the battery life in the settings . It works though
