Battery for iPhone 6s Plus, 4950mAh Replacement Battery for iPhone A1634 A1687 A1699 with Complete Replacement Kits, Two Set Adhesive Strips and Waterproof Seals -High Capacity 0 Cycle

This worked out great for changing the battery in my IPhone 6 Plus. My suggestion would be to do this on a hand towel and have 2 sided tape down to put the microscopic screws on. Before I unscrewed the screws, I drew out the design of the plates that the screws held down. Each plate has a different size screw, doing this was very helpful/Essential. After, everything worked fine again. You just need patience so, don’t be in a hurry.

Love that it has a gasket and three battery glue strips for better heat transfer to the case. I've learned that justtwo strips tends to fry batteries within a year after replacing 3 batteries.

4 Stars because I understood what I was getting myself into. (disclaimer and quick breakdown at the bottom)The first battery:Knowing these things are a hit or miss and could be defective I didn't fully seal the phone up with the adhesives before testing and good thing too. The first battery I received was defective and would overheat like crazy when plugged in. If I were to play a video without it being plugged in, the battery would also heat up, and drained more than it should.The second battery:After that first battery I notified amazon and asked for a replacement, within a couple of days I got a new one. Went through the whole testing process again and the battery is pretty solid. Only gripe is that if you have the phone plugged in and playing a video for a while it will tend to overheat at times, nothing too crazy but hot enough to have the phone pop up with a heat warning and will have to go through a cooldown period, though not as hot as the first battery to where it was almost unbearable to hold.This battery is for my second phone and not used for anything too crazy, and is mainly used when my main phone is busy with something else or is dead. If you're planning on using the phone to watch movies for hours or long videos while plugged in, you might have a rough time. But like I said this only happens sometimes and honestly I might've just gotten a dud who knows. So far its working up to my needs and standards.Battery Life- Good.I'm not sure on exact hours cause I don't use this phone that much but its way better than the old battery. Without much use I charge it every few days when it drops down to roughly 40%. Without use it could last the week if not more.Installation- EasyIf you know what you're doing it's fairly simple. If you're a beginner just be careful taking the old battery out, cause you can short out the phone if done wrong if not worse. Make sure you've got a clean surface for the adhesives. Don't put the adhesives on and screw everything back to normal 100% until you've tested the phone and battery out to your liking first. I think they provided me with tools in the box but I didn't use them. YouTube is your best friend and do lots of research if you haven't done it before don't just assume you know what you're doing just cause.Instructions- I don't believe there were any which makes sense cause liability.Tools- I didn't use them but they look and feel cheap but its a free set of tools. They seem like they'll work for what you need to do and that's it. Which I wouldn't complain about honestly.*** NOTE ***Something to know is that these are not and will not be like your OEM/ standard iPhone battery. These are aftermarket parts and will work as such. For a iPhone battery that's under $30 it works amazing. Unless you somehow get your hands on an original brand new working factory battery it wont be the same.

Reasonable price, shipped quickly, was easy to install, and worked correctly

I was unsure about whether I should replace the battery on my iPhone 6s Plus on my own, but I am glad I did! thanks to this inexpensive, easy to follow battery installation kit. Everything you need to replace your old battery comes with this new battery. The only part that you might need to have some patience with is when you get to the removal of the adhesive strips (only if they tear of course) but you can still do it. Just utilize the tools in the kit, they will come out. It’s been a night and day difference with the new battery, very happy with it.

Only last it 1 year and few months it gave up on June 1st, 2024, FYI ONLY not a complaint for the price guess it did what it did. Wil try a different brand and see how that one will last

Lasted 1 week and then battery quit charging and again Im left with a dead phone after this replacement. Was a good battery until it wasnt i guess.Ordered a replacement and again battery works. However this time I noticed immediately that the phone was overheating dramatically. A hot battery is just as bad as a nonfunctional battery. I might try a 3rd or I may just try another seller. Good luck.

This was a fairly easy install. It's one of the easier installs on a device I've done. The battery lasts all day with occasional use.The trickiest and most time consuming part was removing the adhesive strips from the old battery. Two of the strips broke, and it took extra time to pry the battery out. Aside from that, everything was pretty easy. The video was helpful but I recommend looking at the ifixit instructions for more details about the different size screws.Using a hairdryer to warm up the adhesive holding the case together makes it a lot easier to remove the front panel. Again, using a hairdryer on the back of the phone helps in removing the old adhesive strips.
