[2025 Upgraded] 3600mAh for iPhone 6S Battery Replacement High Capacity for iPhone 6S A1633 A1688 A1700 Battery with Repair Tool Kit and New Repair Screws

Its super easy and works better than I thought it would have. Highly recommend.

Battery is working to full capacity, replacing was tough, tools a little soft, but all is well. Amazon had the battery I needed, where no one else did! Thank you

That battery works worst than the old one , I don recomend it, don’t waste your money.They make me broke my phone with that crap battery

3600mAh for iPhone 6S Battery Replacement High Capacity for iPhone 6S was easy to replace but only runs for 28 hours or so. The phone would go two full days when it was new.

It's kind of hard to rate "Longevity" and/or "Battery Life" having only installed it (maybe) 6 or 7 weeks ago, but it sure did seem to put new life back in to my old, reliable iPhone 6s. I gave those 5 stars any way, but that's why I mentioned it in my review. I loved the extra screws included, as I had taken this phone apart 5 or 6 times now and those two main screws (either side of the lightening cable) had stripped out. Very easy to install and so far, so good!

Specs are better than original OEM battery. Seems to work just fine. Huge improvement over degraded original. Battery rating on old battery was 88% but didn't seem right since it was discharging rapidly during browsing use and had little standby time. Replacement was not too bad although some of the screws inside the phone were really tiny. Suction cup provided was not up to the task but I had another available from a shower hook so that worked out fine. DIY replacement should be doable for those willing to watch a few YouTube videos and dive in.

I watched several “how to change phone battery” videos before changing the battery. That was really helpful! The little suction cup thing to lift and separate the face from the phone did not have enough suction so I used my GPS mount suction cup. Be very careful not to damage anything or lose the tiny screws. Really like this replacement battery! Has a long work life before recharging. Had great and fast seller service too. Quite happy.

There's a reason why Apple makes it so difficult to change the battery. They want you to come to them. I am not sure how good this is. It came with no instructions. I bought it three months ago so I can't return it but that's on me. I should have looked at a video on changing the battery before buying it. Unless you know exactly what you are doing do not attempt to change the battery yourself. Have it done by someone certified to do it. Because I didn't even attempt it I did not damage mt IPHONE.
