BESTMARS Battery Compatible for iPhone 6s, 2200mAh High Capacity 0 Cycle Li-ion Replacement Battery with Full Set Repair Tool Kit, Adhesive Strip, Instructions and Screen Protector - 2 Year Warranty

I was losing battery life on my iPhone 6s, so I purchased this kit. I didn't need the included tools, as I had some from an earlier screen replacement, but it's a nice addition if you don't already have them. The included instructions made the process easy. One suggestion is to take a blank piece of paper and draw an outline of your phone and put the tiny screws in the same place on the diagram as where you took them out of the phone. They are different sizes and it is very important to get them back in the same place where you removed them. I can't stress that enough. The most tricky part of the process was removing the old battery, as the stretchy adhesive strip broke, and I had to pry it off. If you can get hold of it, and pull it out in one go, then it's not a difficult process, but it's more difficult if the adhesive breaks. If you are confused, look up a tutorial on YouTube. All in all, I'm happy with the new battery life. It gave new life to my old phone. If you're reasonably handy with making your own repairs, and you follow the instructions, this is something that most people should be able to do.

Updated JUN 22,2020. 4 months so far and still operates like new...I was hesitant to do this myself, never opened up an iPhone and didn't want to ruin it, also didn't know if the battery would really work well. As it turns out, it was quite easy - just followed the included instructions and looked at a couple different YouTube videos and was done in about 30 minutes. No issues, other than I lost one of the screws... not really worried about that, because the phone was trash with the old battery and now it has new life. Works perfectly, lasts at least as long as when new, and I'd definitely recommend this kit. It comes with all the tools you will need, and then some. Just be VERY careful with the screws - one of mine flew away when I was trying to install one in the metal battery cable cover... it just popped up and off the table, never to be seen again... think the cat ate it :-O

Easy to install. Worked well

I am so glad I purchased the battery. Was a little tough to put the tiny screws back in but I did it. Just take your time. It took me an hour. At first I thought there was a problem because I plugged in the phone and it did not come on after 1 hour. I left the situation and plugged the phone in a week later and after a while the phone came on. Success so don’t get discouraged if it takes a while for the battery to charge. The battery did not have any power in it at all.

I won’t lie, I drop my phone a lot. ALOT. 3-5 a day a lot. Yes I have a case, and for reasons I can’t figure out, have yet to shatter the screen. I was certain my phone was done for, as it wouldn’t work without being on a charger 24/7 and shut off whenever it felt like it. Before shelling out hundreds and breaking the bank, I decided to try a new battery first. $20 vs. $800 seemed like the smart choice and if I lost the $20 I would go ahead and take that small loss. Got the package in the mail, and watched the video on YouTube and was immediately overwhelmed with the thought of having to do this so luckily, my boyfriend decided he would try to replace it. Thank god! My anxiety was in full affect thinking id have these tiny screws scattered about and me searching everywhere for them should they have fallen. I stood behind him like a back seat driver biting my fingernails and anxiously waiting for those tiny screws to fall. So thankful my anxiety doesn’t phase him. He opened my phone and there were two of the original screws just rolling around in my phone! Now I saw why my battery was at less than 50% health and why it would shut off randomly. Nothing was held down in place! He changed it in 10 minutes. Held my breath to see if his magic has worked and albeit, a sigh of release! My phone works again! I don’t have to lug around a portable charger with a 6 foot cord hanging out of my pocket anymore (although I did for an entire day after out of habit)! Thank you. You guys saved me a lot of money and my peace of mind.

I was a little worried at first after what I read, Some of the bad stories. But I felt like it was fairly easy, you just really have to take your time watch YouTube videos and read the instruction. If you’re not generally handy I would not attempt it.Make sure to take your time with the adhesive strips on the backside of the battery.Day 2

I held onto this battery for months before installing. I finally did it and was very pleased at first. The video was very helpful and made the process pretty simple (although I did crack my screen and had to replace that too). Two weeks later and I’m shopping for a new phone. The battery only charges to 22% and I don’t dare try to replace it again and crack the screen again. At this point it’s more cost affective to buy a new phone.

Initially was very impressed with the capacity, but the battery quickly degraded and had the same or less capacity than the degraded factory iPhone 6s battery I replaced after 9 months. If you only need to get a few more months out of your phone this might be for you. Otherwise I’d keep looking. Easy to install with the provided tools.
