Replacement for iPhone 6S Battery, 4000mAh High Capacity Li-ion Polymer Replacement Battery for Model A1633 A1688 A1700 with Complete Professional Repair Tool

I've done a number of battery upgrades on iPhone 6s phones (as well as other apple phones and devices). I'd say this kit is arguably the best I've encountered for the iPhone 6s - especially in terms of overall presentation and the quality of the tools. The bits and screw driver was noticeably higher quality, as was the little blue pry bar.I installed my battery on 3/7/2025 and will provide periodic updates here as to how everything is going.UPDATE: 3/9/2025 - so far so good! Had the battery in for a few days now and it's definitely a big change from the one which was failing. Here's the history: bought my iphone 6s new from Apple in 2015. Original battery made it until 2023, so close to 8 years. When that battery failed, I installed a Lithium Ion one from amazon (made by a company going by the name of "Lotus". It was a 2200 mAh battery and lasted a couple years. When it started to fail, I ordered this replacement. So with the Lotus battery, near the end it would rapidly drain and fall off a cliff. It would accept a charge very rapidly and zoom back up to 100%, but once you took it off the charger, it would drain rapidly. If using the hot spot, maybe I could get 30-45 minutes off charge. If I went to sleep with the phone at 100% charge - even if I turned off the hot spot - most times I'd wake up and it would be barely clinging to life at 1 or 2%. Since installing this new battery from BEBAT, the phone is reacting much differently. Charging is a more drawn out process (which is good, because that's telling me hit has capacity in the battery now). If I remove it from the charger - even when using as a hot spot - phone lasts much longer. If I charge it up and go to sleep, when I wake up it's only lost maybe a couple percent tops and basically is still fully charged in the morning. When talking on the phone off the charger, it barely impacts the charge state, whereas before (with the Lotus 2200 mAh battery) it would drain down to 20% within a few minutes basically. So that's been a big improvement. This BEBAT 4000 mAh battery also says it's Lithium Polymer, whereas the older battery was just Lithium Ion. Not sure what the exact implications are, but so far we are off to a good start. I will continue to provide updates here, as this is one of the few batteries still available on Amazon for the older iPhone 6s crowd. So far though, A+More updated coming in a few months...UPDATE: 03/22/2025 - It's been 2 weeks and all I can say is phenomenal. My iPhone has been working amazingly well with regard to battery life. I go to sleep with it at 80% and wake up 8-10 hours later and it's still at 78 or 79% - wow! I don't know if it even held those sorts of levels when it was new. This battery has allowed me to break the chains of worrying that my trusty iPhone 6s will die when I'm out and about. The battery just seems to go and go and go - it's crazy. I'm pretty careful to mostly keep the charge level between 20% and 80% and over the last week it seems like the battery has actually gotten better at holding a charge. I don't know if this is because it's "broken in" or cycling the battery has improved its health or what; but at least thus far, I cannot be more happy.No swelling / no overheating to report as of yet. So that's encouraging. So far, 100% amazing.More updates to come...

liked everything about the installation instructions and tools supplied

Seems to be holding a charge for all day!

Battery last about one day if the phone is not being used. Im not impressed. Especially for a battery that claims to be larger in capacity than the original phone battery.

I now have about a day of battery life compared to 3 hours. Everything was included and needed/used. Second time (ever) replacing a iPhone battery. That’s the easy part. Second time screwing up the glue/tape. Would buy again.

Everything I needed in the kit except tweezers and the battery works well!

I managed to fix my old iPhone 6 that I now use for other purposes.This was a great choice.

Correct iphone 6S battery was sent. Tools included are useful. Installation instructions were for a completely different phone, showing parts to be removed that the 6S doesn’t even have.Saved by YouTube!
