Battery is as advertised

Works as it should. Install was smooth
Size: 13 Pro
Just as advertised. Follow the video on how to reset the phone after the repair so it sees the battery as genuine. The plastic scrapers aren't good enough to clear the residue imo. Use a small flathead screwdriver or #17 exacto blades.

Everything it promised to be. Iphone 14 battery
Size: 14
i've never left a review for anything before, but this company deserves a good review. The battery was everything it promised to be and the instruction video was on point. I just installed this last night so can't speak to longevity but if it holds up, I will definitely be buying more batteries from them. The screwdrivers were pretty well useless, but I have my own so that wasn't a big deal. overall, very good experience for the price.

Difficult and time consuming!
Size: 12Pro Max
The battery itself is fine and the 100% charge is lasting approximately 2 days. The screwdrivers included with the battery were basically useless. I was able to remove the one outside screw and the other one seemed stripped or was it the screwdriver? With the one screw still in place I started trying to remove the screen. That process was extremely difficult. Finally got the screen open and there are two ribbons (with wires) that you are supposed to remove so you don’t break them. Again none of the screwdrivers worked and I couldn’t remove the parts to remove the ribbons. Top one broke. Removing the battery was difficult. The battery plugs in the phone under one of the plates I couldn’t remove so I had to pry it up and popped the screw out. Got the old battery unplugged and the new battery plugged in and battery in place. The popped out screw could not be replaced because it was too small. I turned the phone on to make sure it was working and replaced the screen. This process took me 5 hours! The battery had 54% charge so instructions said to not charge until it went to 0% and turned off. Then charge to 100% and leave on charge for an additional 1-1.5 hours for a soak charge. Then repeat the charge process 100% down to 0% turns off and charge again to 100% with no partial charging 5 times. I personally will never decide to replace my phone battery again.

False advertising, completely unreliable battery
Size: 14 Pro Max
The listing claims no unknown part warning, yet the alert pops up nonstop. Battery life is abysmal, nowhere near 4323mAh. The toolkit is low-quality disposable junk that ruined my repair process. Avoid this scam product at all costs.

STILL TRIGGERS BATTERY WARNING!
Size: 14 Pro Max
YES, POP UP WARNING! Sadly, the iPhone sees this battery as not normal. So far, it seems to work okay, but it’s only had one cycle. Also, ,the glue gasket was unprotected (not in a little plastic bag) and so had cardboard fibers stuck to it. I will update if things go south. For reference, this is for an iPhone 14 Pro Max. I have replaced three other batteries on iPhones, so am not new to the process. The mediocre rating is not only because it does not live up to its primary claim (no pop up), but a few other problems that could turn into issues. Firstly, the phone got stuck in an endless white-screen spinning thing when it followed the ‘Battery replacment’ warning. After 10 minutes of waiting, I just hard-reset, and it seems to be working. As for the kit: The blue gasket to reseal the phone was not in a protective bag, and so the exposed edges of the gasket stuck to the little particles of paper from the cardboard box it came in. I had to spend some time using tweezers to pull out the fibers, and a few were too deeply embedded in the glue. The tools are really cheap but everything worked.
