Review: 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.
Review: Would buy again, but not 5600 mAh - Would buy again for sure, value for its price. Phone was initially below 80%, and now it lasts the entire day without having to charge mid-day. Recommend following ifixit guide and a couple youtube videos(pro-tip: be very careful with the flex cables(black cables) when unplugging things). After a week of usage and checking the analytic logs, the nominal battery capacity is at 3745 mAh which is around 101%-103% above the normal apple battery which is usually around 3687 mAh- most likely not double the capacity as marketed. Nonetheless, happy with the product and would buy again for doing its job.

### ⭐⭐⭐⭐⭐ Would buy again, but not 5600 mAh
*by T***. on March 28, 2026*

### ⭐ Don't waste your time or money, new battery doesn't hold its charge past 12 hours.
*by D***A on April 18, 2026*

Installed in my wife's phone. Comes with a complete tool kit, but the instructions seemed to reference another phone model (not the iphone X). Make sure you cross reference with several good YouTube videos. My wife's phone would be dead by morning, and I was hoping this battery would restore its performance. Well, now if the phone is at 100% charge when she turns in, it will be at 50% by morning. Not exactly the performance I was expecting. I have replaced many phone and Ipad batteries and this has been the weakest replacement battery by far. Quite disappointed. I was hoping all these different batteries were all the same so I gambled by buying the cheapest one. I lost. Buy one of the more expensive units that cost $25-$30.
