Upgraded Battery for iPhone 6S, (2025 New Version) [11800mAh] Battery Replacement for iPhone 6S A1633,A1688,A1700 with Complete Professional Repair Tool…

This kit contains everything you need to replace an iPhone 6S battery. The new battery life is great. I was nervous about attempting this myself but given the phone is old and the cheap price for this kit, I figured why not as if I break the phone no big deal. To do the repair, I recommend two sources: Read over the written iPhone 6s Battery Replacement guide from ifixit for an overview and tips, they leave out some stuff like applying adhesive though. Then watch the Youtube video from RickMakes titled 'Replacing the Battery in an iPhone 6s' as he uses an identical kit and does mostly everything you'll need to do. INSTALL TIPS: I recommend draining your old battery completely until your iPhone shuts off automatically before doing the replacement to decrease the chance of fire. BY FAR the hardest part of the procedure is removing the old adhesive strips underneath the old battery. I followed the video but one strip broke while I was pulling it out and when that happens it's a pain as the old battery is tougher to take out. The ifixit guide has tips on what to do if this happens to you. To make pulling out the old strips easier on your first try, the RichMakes video doesn't do it but I recommend following the optional step listed in the ifixit guide of taking out the Tactic Engine, it's quick and easy to remove and doing so should make pulling out the old strips easier as it won't catch on it and rip like it did for me. Doing that and heating up the old adhesive to loosen it are required steps IMO. Do a test install of the new battery without the adhesive strips first so you can see how to place it and plug it in. The battery can move very slightly when placed inside so determine the best location now as once you place the adhesive on and press the battery down, there's no going back. When you remove the adhesive cover for the new battery adhesive strips, double check it's the correct side you pull off. You want to pull off the BLUE SIDE FIRST as the video does, I was in a hurry and pulled the pink side off first. You destroy the strips if you take the pink side off first, I had to order new ones but luckily they are only a couple dollars. Once the adhesive is on, carefully place the battery in the position you determined from the previous step as like I said, there's no going back.

I replaced the battery on a 6s. This is not my main phone so I felt comfortable doing it. Take your time, don't rush it. It took me way longer than expected. The hardest part was removing the old battery because the glue strips broke halfway through removal (see video). This means I had to pry the old battery out very gently and bending the battery slightly was not avoidable. The video does not show the case gasket which is included in this kit but with logic, I was able to figure out orientation. This kit had everything, even the different screwdriver bits. Make note that on the metal display cover that covers the flex cables and battery cable, there is one screw longer than the other. Take your time and go slow. If this is for your main active phone, you may want to inquire how much it would cost to have someone else do it. But after just doing it once, I would do it again.

Based on other reviews, individual battery life seems to vary considerably. For what it's worth, I fully charged the battery after installing in my iPhone 6S, then let it run down for a week. (Condition: all apps closed, NOT in airplane mode so wifi & Bluetooth radios active & battery health meter showed 100% maximum capacity relative to new. ) It ran for six (6) days before reaching the 50% mark. Starting 08/10 4:15PM = 100%, 08/11 8:31PM = 97%, 08/12 5:53PM = 89%, 08/13 10:48PM = 77%, 08/14 10:36PM = 67%, 08/15 6:47PM = 60%, 08/16 09:29PM = 50%. Even two days later - 8/18 at 7am - the charge read 36%. A one week standby test is by no means definite - and I doubt personally that the battery actually has 11,800 mAh capacity - but so far I'm optimistic about quality and pleased with my purchase. The rest of the included items (e.g., tools, gasket) worked fine. Opening up the phone was the usual headache; find your favorite procedure video online.
