[5500mAh] Battery for iPhone SE 2016 1st Generation, Upgraded New Version High Capacity 0 Cycle Replacement Battery for iPhone SE First Gen Models A1662, A1723, A1724 with Professional Repair Tool Kit

This is a nice kit if you need a new battery for your iPhone SE (1st generation). I’ve had my SE since Sept. 2017 and don’t want to replace it yet as I really like its size, but was having problems with the battery despite it having 85% capacity, which I would have expected was still adequate for decent usage. It was draining very fast although I’d changed a lot of settings to reduce battery consumption, and occasionally when it was fully charged, after being on the charger for hours, would suddenly shut down, start up with the screen showing the battery was drained, then immediately show 100% charged as soon as I plugged it into the charger. Strange behavior.I will say the kit wasn’t well packaged by Amazon. The kit is in a small box with a flap that is held closed magnetically. It was shipped in a much larger box but was not padded at all, so it was banging around in the shipping box on its travels, and the kit opened up and all the tools, etc. were scattered around in the shipping box. Not good, especially with a lithium battery. No damage to anything fortunately.There are no instructions in the kit, just a sheet with links to youtube videos on how to change the battery. Watch the video in the link, and a few others you can find there, before you start. Also watch the video “Averting iPhone SE battery replacement disaster!” and “How To: Remove & Reapply iPhone Battery Adhesive Strips” These will save you grief, as the adhesive strips, for me and many others, are the biggest obstacle to this job.Changing the battery requires working with very small screws and other parts in the phone. The kit includes what you need: a nice handle for the bits (pentalobe and Phillips) required for the tiny screws, tweezers of the right size for picking up those tiny screws, and the other tools needed to get the screen open and the cables free. I recommend you have a good magnifying glass on hand as well. I’m quite near sighted so normally I can get a good view of small objects by removing my glasses, but even so I found a magnifying glass helpful for some of this work. The pentalobe screws you first remove at the bottom of the case, near the charger port, probably have some dust & debris in them, and you should remove this with a pin first so the pentalobe bit will seat well when you remove these screws. The screwdriver/bit combination is magnetized which is great for the screws inside the phone, but the pentalobe screws seem to be a stainless steel that magnets don’t attract.Work carefully, patiently, and keep track of which screw goes where. Don’t mix them up or lose them! Tiny. I’ve done a lot of this sort of work, from upgrading memory in the Mac Plus in the ‘80s to recently fixing/baking a video card in a 2009 iMac. This is definitely one of the more challenging jobs - take your time and take a break if you have trouble. You can do it, but you need patience and a steady hand. The biggest problem for me was the old adhesive strips that hold the battery in place. The videos show them coming right out, but lots of people, including myself, experienced them breaking instead of pulling out. I could barely get hold of them before the little I could grasp ripped off. I used the technique with thread to saw through the adhesive (from the video above on “Averting iPhone SE battery replacement disaster!”), which took most of an hour to do and maybe 10 yards of strong thread. No fun, but it worked. I later discovered the other video “How To: Remove & Reapply iPhone Battery Adhesive Strips” which also has a good method for dealing with this problem. The adhesive strips that come with this kit use red and blue backing like those in the video, only for mine they are reversed, meaning what was the red backing in the video is blue in my kit, and visa-versa. I needed to adjust how I put the new strips in accordingly. If I were to do this again, not sure I’d use them at all - maybe I’d use some double sided tape instead to make it a bit easier.All together it took me about an hour and three quarters to do the whole job, much of which was coping with the old adhesive strips.It’s only been a couple of days, but so far I’m quite happy with the outcome. The battery holds a charge at 100% much, much longer than before, and doesn’t lose its charge nearly as quickly. It’s like new or maybe better than new, as this is rated for a higher capacity than the original battery. All in all, a good kit and a nice price. I’m happy.

Before I review the battery kit I want to share the issue I was having with my iPhone. I let my iPhone SE get to hot in the sun about eight months ago and it shut down. I had to let it cool down and plug it in before I could reboot it. Since that time, not only was it’s battery life shortened in between charges, but it would always shut down in mildly cool temperatures ( below 50 degrees Fahrenheit). In order to reboot I would have to plug in the phone and bring it to room temperature. After rebooting, the battery percentage would show 2-3%, after being at 100%, until I turned it off and rebooted it again, at which time it would show 100%.I watched several videos as well as the one that was linked to the kit. The one that was linked to the kit was well done and useful. I had difficulty removing the glass with the suction cup, but eventually got it. I think I was being too careful. Other than everything being very small, everything else went well. I actually did not disconnect the three connections to the glass as I felt I could support the screen well enough. I only disconnected the home button and battery connection. However, removing the glass would allow easier battery removal, and the connections looked rather easy to remove. Give yourself an hour and have good lighting. My phone works perfectly now. Have even used it twice for several hours at temperatures in the 20’s, and battery life is just like new.

The battery installation went very well. No problems removing the original one. When I turned the phone on after the installation, it showed the new battery at 39% charge, so I plugged in my regular charger. The battery would never charge, and the phone began self re-booting every few minutes.I removed the new battery, and reinstalled the original one, but the same symptoms remained.Finally, the only way the phone would work is on the charger, but only for a couple of minutes. Then it would self reboot. It would do that perpetually, as long as it was on the charger, but would go dead without the charger. When it was on, all the phone features were intact, but it wouldn't stay on.The phone finally died completely.Everything was fine until the new battery was installed. The only reason I put the new one in was that the original one was now needing a daily charge, rather than lasting most of a week as it had in the past.So far I can't get the seller to respond to messages, and Amazon doesn't have any contact information other than what is on the seller's info page.Very bad experience. This battery ruined my phone.

A challenge to install myself, but I did it! Now my phone lasts 2 days between charge ^_^
