XYIRMCYF 21800mAh Super Capacity Battery Compatible with iPhone 11 Pro Max, 0 Cycle Li-Polymer Replacement Battery for iPhone 11 Pro Max, with Professional Repair Tool Kit

Great replacement option, durable enough and easy to install with the right tools and knowledge installation should be simple enough. 100% battery life displays after installation and have had no issues with overheating or anything like that. Seems efficient and reliable not to mention budget friendly with good quality

Battery is horrible. I received this yesterday and it was at 40% charge. It took 24 hours to charge to 100%!! used phone for 10 mins and it dropped 69%!!! Second night THE BATTERY IS DRAINING WHILE IT IS BEING CHARGED!!! It only charged to 91% and I woke up to find it charging at 81% !!! Battery is a POS! I wrote the seller yesterday and so far no answer! I can't return it without not having a phone!! This is the second battery that I purchased on Amazon this week the first was DOA seller refunded immediately! Five minutes after I contacted him!

We got this for our son's older model galaxy (S9+) until we figured out if we were replacing the phone altogether. I have to say, I was pleasantly surprised. My son said by 3pm, his phone was at 10% if he was lucky. Now after replacing the battery, by the end of his school day he's at 38-40%. The only complaint I have is that there were no instructions. My husband is techy enough that he could figure it out, but if you're not techy, please find someone who is. Would recommend.

This battery kit is fantastic for the iPhone. Went from performance problems to max performance right after install. Battery like comparable to OEM battery. The kit included everything I needed to get it installed in the iPhone.

I was bracing for a frustrating install, but this battery swap was easier than I expected. The included tool kit covers what you need, and as long as you take your time and follow a good step-by-step video, it’s very doable. The real win is the result, it’s great to have an iPhone 11 Pro Max that lasts again. No more watching the percentage drop like a countdown timer, it feels like the phone got a second life. If you’re comfortable doing a careful DIY repair, this is a solid upgrade for an aging battery.

Battery defective bulging and doesn’t fit in phone

This battery replacement for IPhone 11 Pro Max is a great deal! It includes everything you need to change out your battery’ This kit even includes the tools! Changing out your batteries is much easier than you think and sooo much cheaper! Your 11 Pro Max will work better than ever, holding a battery charge like it did when it was new! The battery is a perfect fit, making the installation a breeze. This kit didn’t sacrifice quality or durability in this aftermarket version. It is pretty quick moving when you calm down and get going on it. I definitely recommend this battery kit! You’ll save a

Battery worked for a week no problems or anything!!after the week phone would turn off randomly and battery would stay at 1% percent even if u would charge it
