TQTHL 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.

I just installed the replacement iPhone 6s battery yesterday, and it seems to be working great today. As long as it holds up, I would give the battery and installation kit five stars. However, be forewarned that installation is not as easy as the Youtube videos you may find make it look. I knocked off one star because I feel that installation could have had better instructions. I'll try to give some additional tips. 1) There were no written instructions with the kit. They gave you a card with one of those square barcodes to scan to bring a Youtube video up on the phone. But wait, you are taking the phone apart. Better have another phone handy. There is a written URL that you can type into a computer browser, but it took me to a Japanese web-site that didn't appear to have anything to do with phone batteries … just Japanese text. I was able to search and find the same video on the computer that their barcode brings up on the phone, but as I said, it makes installation appear easier than it really is. 2) Using the supplied suction cup and prying tool to open the case is stressful. You have to pull hard on the suction cup and I was expecting the display to crack. I gradually got more and more aggressive with it, and eventually got the display to give enough to allow a thin pocket knife blade to slip under it. Then their plastic pry tool (which is much less likely to slip, scratch or chip the display, or cut your finger). 3) When I pry things, I usually start at a corner. In this case, there is extra adhesive at the corners of the iPhone. I was finally able to get the separation started just below the round control button on the display. The video could have mentioned that is the sweet spot for getting started, but didn't. 4) Once started, it is pretty easy to pry the display off of the case until you get to the top. If you try to pry the top straight up, you will just snap the pry tool. There are tabs at the top so you have to swing the display away from the case like a hinge. The video shows it done that way, but doesn't mention that you have to "hinge" it open. It does warn you not to hinge past 90 degrees. Good advice, but later, when I had the phone open and was trying to reconnect the display, it slipped out of my hand and fell back to 180 degrees. No harm done except my heart stopped. 5) When you remove the "brackets" holding the connectors down, they don't warn you that the sets of tiny screws for each bracket have different lengths. Better watch for that and keep track of where they go. 6) The rest of the disassembly went well until I got to battery removal. I got the Command Strip end loose, and very slowly and carefully pulled it straight back just like the video showed. It quickly snapped in half. I did the second one even more slowly and carefully. It snapped too. I suspect that you should apply a healthy upward pull to the battery away from the case while you pull the Command Strips out. Use all four hands (haha). The video doesn't say to do that though. So I had to pry the battery out. I punctured the battery doing that and it emitted a sweet odor. Fortunately, no sparks, smoke, or fire but I got it out of the area just in case. 7) Battery installation and re-assembly went well, except I am sure glad I checked operation before snapping the display back on. For some reason, the display was blank. There was no sign of life when I turned the phone on. All the connectors had snapped into place and looked level and fully seated. But I had to disconnect the display and reconnect it before the phone worked. Whew! Test before you snap! 8) Kudos to them for including the gasket because prying the case apart destroys the original one. But the video does not cover installing it at all (or removing the old gasket with some king of scraper and your fingernail). It is a very thin, sticky, rubbery gasket that comes sandwiched between two sheets of plastic. Remove the larger piece and be sure the gasket stays on the smaller sheet. Lay the smaller sheet inside the case perfectly centered so that the thin strips of gasket material lay perfectly on top of the tiny little edge of the case. Then press it down onto the case edge, trying not to slip and buckle the plastic sheet which then mis-positions the gasket. Good luck with that. Once perfectly positioned on the little edge around the case and pressed down, you have to peel the plastic off of the gasket, while helping the gasket come off of the plastic, not off of the case edge. Again, use all four hands (haha). 9) With battery in place, connectors seated and secured, gasket installed, and the phone operation verified, it's time to snap the case together. You have to get the tabs on top started first with the display angled upward, then hinge the display down onto the case and snap it closed. First I tried to snap the display straight down onto the case. That doesn't work. Try to get it right the first attempt or you could make a mess of the thin, sticky, rubbery gasket. The video shows it being done correctly, but doesn't point out the fact that there are tabs on top to deal with first before hinging the case together. I think this is a quality replacement kit, but the instructions (video) are over simplified. I hope this helps others who dare to be do-it-yourselfers.

It's a decent kit for the price. I like how everything was included. The battery is definitely not 11800mAh. Do you really think that somehow this company can 10x the capacity of the battery that Apple engineered, while keeping the same size? Ha! I found the battery performance to be worse than the original battery, not 10x better. Maybe it was a typo and it was supposed to be 1180 mAh? The original Apple battery is rated for 1715 mAh. Just leaving the phone at idle for a couple days the battery dropped by 15%.

I've installed three of these batteries in differnt iphone 6s and they work great. The battery itself is heads and shoulders better than the OEM Apple batteries both in quality and capacity. The OEM 6s battery is 2750 mAh while this battery is 3200 mAh. The one I've been using for 1.5 yrs now is still showing 100% battery capacity, which is much better performance than any Apple battery I've had. If you decide to put a battery in your iphone 6s I would offer these recommendations and they have nothing to do with the battery itself. The installation tools that come with this battery are not the best so I'd advise buying a decent iphone tool kit prior to installing this battery. The two screw drivers that come with the kit are so small they are near impossible to use-especially if you have big hands. The screws that need to be removed to install this battery are very, very small so you need good lighting and if you have a bench light with magnification that would help greatly. Also using magnetized screw drivers are a big help. Also note that the two plates that need to be removed to disconnect the display and battery ribbon cables have 3 short screws and one long screw, so pay attention to where they go. One last suggestion: after you've connected the battery and ribbon cables and are ready to put the display back on the phone case, turn the phone on as usual. The batteries come with a partial charge and the phone should boot up. If no joy plug the phone into a charging cable and make sure the you see the apple logo. If not you may have a cable that is not fully seated (speaking from experience).

Easy to replace, took less than ten minutes. Not even close to rated power, says maximum capacity 100% but drains just as fast as the battery that was replaced that sat at 79% maximum capacity. Very disappointed.

Great product and great video instructions.
