[7500mAh] Battery for iPhone 6S (2025 New Version), Conqto New Upgraded Higher Capacity 0 Cycle Battery Replacement for iPhone 6S Model A1633, A1688, A1700 with Complete Professional Repair Tool Kits

The package contains everything (battery, suction cup, plastic clips to open the phone, magnetic screw driver/bits, tweezers, and adhesion strips for battery and iPhone, (also a sim removal tool- not necessary for battery replacement)), necessary for swapping batteries, but the instructions. I watched a video on swapping the battery and paused it at every step. You need to force the plastic clip between the display and back case to open the case, the suction cup just helps to open the case. Neither the display or back of the phone are damaged, you just need to use more force than you might want to. The connectors for the display and battery also use more force to disconnect than I was comfortable with, again no damage. the process turns out to be pretty easy once you go through it. It took about 20 minutes.The best advice I can give is on placing the new battery in. Put the new battery in first without adhesive and test it to make sure it works and will charge. If, everything works, it is easy enough to pull the phone apart again take the battery out and add the adhesive. If the new battery doesn't work or there are problems, it is much easier to put the old battery back in. Second best advice, is to use a finger to push the display and battery connectors back in. You have a better feel for when they pop in and are well seated.I made the mistake of putting adhesive on the new battery and placing it in the phone before testing everything. I did turn the phone on before closing the case, making sure the battery powered the phone and the display worked properly. But, after sealing up the phone and powering it on, I had problems. The phone seemed slow to boot up and the battery level was dropping pretty fast (1% every minute or so). The internet connection seemed slow. The phone started to reboot every minute or two, even after plugging it in. The battery would not charge past 20%. I tried several things to fix it (including connecting to iTunes and a hard reboot), nothing worked. I thought I had a bad new battery and decided to put the old one back in. Even with the adhesive taking the phone apart took less than five minutes. On putting the old battery in, I popped the connector in with a finger and noticed it popped in. The connector laid flatter than the new battery's connector. I swapped the battery with the new one and pushed the connector in with a finger. It popped in and laid flat. I connected the display and turned the phone on. Everything worked much better. Boot up was noticeably faster, battery charge level was higher, battery charged and no longer rebooted. My problem was bad battery connector contact. The phone works fine. But, I don't have all the adhesive I should on the battery and case, because I didn't thoroughly test everything before committing the adhesive.So far the new battery works fine. This is the first morning with a full charge. I've used the phone (several times over the last 8 hours) and battery level is still at 80%. I would have had to charge the old battery several times by now, or used it plugged in.The battery works (no heat on charging) and it came with a nice tool kit. I'd buy from them again, if it's ever necessary (I have an old iPad).

Works awesome, no issues, battery health is at 100% again. Very happy

This is my dad's old phone be stopped using it because mainly the battery died so quickly so it been sitting in a drawer for years I've used it a couple times but had to leave it plugged it went from 68% maximum capacity to 100% it took me about an hour and a half to fix (I've never done this before as a middle schooler) it cam with everything you need from a screwdriver to the sticky adhesive to hole the battery down I will say the tool to get up the screen is pretty crappy considering it broke when I tried to get the battery up it's definitely a good value because a place charges 60 to replace for the most part it was easy it charges kinda slow but I just installed it so I'll give it some slack the power is great before with the old battery if I had it on my desk for 20 mins it would die but now with the new battery it only lost about 2% Thanks for the new phone basically!

This battery worked fantastic, but only for a month. This was for my iPhone 6s. The backstory with this phone was that it was a great phone from 2019 when I bought it new, up until I updated to IOS 15, which was a big mistake. Right after the update, the battery life took a huge hit, and even after a year, the phone needed to be plugged in to use it for very long. Battery health was 85%. I replaced the oem battery with this one. It was a 3 day battery at first, but then after a couple weeks I noticed that it started to become a 1 day battery. They from a full charge the battery would go dead in 20 minutes, or less, just like the original battery. One lesson from this is don't update your iPhone more than one or two year updates ( ie. ios 13 to ios 14 but not 15, or ios 16 to 17, but not 18) It seems like apple doesn't mind releasing updates to phones even if it comes as a detriment to battery life and storage space. I haven't had this kind of problem with android phones.
