DEJI Battery for iPhone 6s, 2200mAh High Capacity Replacement Battery 0 Cycle, Professional Full Set Tool Kits with Instruction and Screen Protector -[2 Year Warranty]

The battery and the extras are packaged in a way that screams quality. That battery itself appears to be well manufactured. I had no problems installing this battery, but I’ve done battery replacements before. Battery fired up at 53% and charged fully. Very satisfied so far. I will update this review after several months of cycles.Update: I have cycled this battery at least 10 times now. It is a solid battery that will last me all day with heavy use, and might last two days with light use in power saving mode. Very linear and predicable battery dissipation. The manufacturer claims that the first couple of cycles might offer less power, and that was my experience as well. Very happy so far.Update 2: I have used this battery for 2 months now without the slightest problem. I uploaded an image of the battery level, representing moderate use, for the period between 6 am and 8 pm (14 hours). The battery is at 60%. Buy this battery ... no more questions need be asked.Update 3: 4 months now, zero problems, battery still at 100% capacity. I like this battery so much I recommended it to a friend and installed the battery for him.

Don’t buy this battery. After 2 months it gets swollen. Now my iPhone 6s is not working anymore. Try to avoid buying this low quality battery.

Installed this on my daughter’s 6s. Took about 10 minutes to do. Once the battery is conditioned, and charged to 100% it lasted almost three days. That’s with a teenager using it too! Comes with all the tools needed for the install and a bonus screen protector. Easy to follow instructions with photos. Here’s a tip, there is no need to disconnect the screen digitizer. Just take off the battery wire cover and disconnect the cable. This will save you about 15 minutes of frustration trying to disconnect and re-connect the tiny ribbon cables for the screen. Taking off the screen just gives you more room to work.

Put this in to replace my 3.5 year old stock better. Wow way a difference it makes. Like having a whole new phone. The install was worse than expected for my phone. The screen didn’t want to pull away at all using the suction cup and the battery really had to be pried off which is sketchy since they can catch fire. All in all, worth every penny.

I was a bit skeptical of purchasing a "non-Apple" replacement for my 6S but I had missed Apple's $29 replacement offer and my Iphone was not holding it's charge well at all. I am not a heavy user at and my phone would hardly make it through the day without charging. I have never attempted a battery replacement before but thought I didn't have too much to loose as my phone was rapidly becoming almost useless.On to the battery from DEJI. The battery comes complete with all of the tools necessary to make the exchange. Very well packaged and all pieces of good quality. I carefully followed the instructions in the package along with having watched several YouTube clips. The replacement went exactly as described. I carefully went step by step so it likely took me longer than many to do the exchange but, it went perfectly. The phone powered up just fine and received it's first 100% charge-that was 3 days ago! I haven't charged it again yet and I have been using my phone more than I used to. WOW! Why did I wait so long to do this? Great replacement battery and kit from DEJI for my Iphone 6S.

I bought this battery because my aging standard Apple iPhone 6s battery was at 75% of its original capacity, which meant it rarely lasted all day. The packaging feels well-designed, and it comes with everything you could need to replace the battery. I would recommend watching at least one Youtube video before you start. Follow their instructions and you should be fine, with a couple of notes:1. I had a really hard time getting the display assembly to come out of the body after unscrewing the bottom two screws, so I'd recommend (as the instructions do) having a hair dryer on hand to heat up the adhesive.2. The adhesive strips to hold the new battery in place are very sticky (duh) and easily get caught together, rendering them unusable. I screwed up the first one, so I was only able to use one. Be very careful when removing them from their backing, and go slowly so as to not stretch out the adhesive material too much.

This replacement kit came with all the necessary tools to safely take my iPhone apart and install the new battery!!!I’ve never done this before, and with the help of the directions and a couple of YouTube videos it went so well!Would ABSOLUTELY recommend using YouTube tutorials for battery replacement, as they kind of talk you through it. Also when removing the old battery be very careful because I almost punctured mine!

Easy enough to install using YouTube videos to guide me through the process. Screen protector could be of better quality. Overall this kit contained everything needed to replace my iPhone 6s battery and only took me 10 minutes. As long as your careful not to extend the screen past 90 degrees when disconnecting the cables and to pull the entire original glue tabs straight out, then you should have no problems
