[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

First thing to know... Today is day one of replacement. This review has nothing to do with how this battery operates as i won't know until i give it a test run. Yes this product had a downfall ( it didn't come with any instructions or even a link or QR code to find help/support) BUT for the price and for everything else that was included with the set i was very pleased overall. It is not the sellers fault i decided to shop for a cheap deal, so i am trying to leave a review that is fair. If the battery itself does not hold up to a reasonable expectation i will for sure update this review and add it to the very top of my long winded speech.*** VERY IMPORTANT TIPS FOR SUCCESS!!! READ ALL BEFORE STARTING!!! OR ELSE... ***1. When removing screws and the covers, be sure to set the cover down with the screws laying down next to original slot. NOT ALL SCREWS ARE THE SAME LENGTH. SCREWS MUST BE INSERTED BACK INTO ORIGINAL PLACE. IF THIS STEP IS IGNORED YOU COULD DAMAGE YOUR PHONE TO THE POINT THAT IS DOES NOT FUNCTION AT ALL.2. Make sure phone is off BEFORE replacement / disassembly is started.3. Using a hair dryer WILL be your best friend. You WILL need to heat the phone up to the point where it is almost hot* (approx. 60 seconds about 1” away from surface of phone) to the touch during two steps. First time is after you remove the L & R screws next to the charger port, you’ll heat up the front and back of the phone before you use the suction ring to pull up on the screen (first point of entry with the guitar pick shaped object will be to the left of where the left bottom screw was next to the headphone jack port). The second time you’ll heat up the bottom portion of the phone will be when you pull the old glue tape tabs out from under the old battery, pull slowly and try your best to take the entire strip out in one piece.4. Remove the SIM card after you turn the phone off before you start ANY of these steps. The SIM doesn’t store any data BUT that’s how your cell phone makes calls and functions. Very important.5. My set I bought from this seller DID NOT come with any instructions, nor did it come with a link to go too for support. I spent 20 minutes watching YouTube videos that had similar tools involved; 100% recommend doing the same. This was my first time trying to replace an iPhone battery in an iPhone 6S 128GB from 2015.6. If you care about saving contacts, photos, texts, notes then make sure to BACKUP YOUR DATA!!! USE THE CLOUD OR AN EXTERNAL DEVICE OR LAPTOP BEFORE YOU TEAR YOUR PHONE APART.7. Slow is smooth, and smooth is fast? Or something like that. Between unboxing the product and watching 20 minutes of YouTube and hunting down a hair dryer… the entire experience took me approx. 90 minutes. After doing it once, I feel like an appropriate amount of time could be 30-40 minutes. So, take your time, don’t skip “small steps”, do it correctly the first time. Don’t be ‘that guy’ who rates this item with 1 star because you didn’t take the time to do it correctly.8. Don’t make fun of my drawing. I am not an artist, but I prefer drinking water without ice in it so that’s going to have to work.

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 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.
