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!

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).

So, I think those adhesive strips always tear off too early, and that's a prying shame. Go slow. I didn't need the hair dryer, but use only the little plastic pry bar, and go slow.I used a video to jerry rig it, and very helpful. I even got the job done with 2 old side-to-side cracks in my screen (covered with clear packing tape before starting, and it came off easy at the end). Phone is now connected, functioning as before, and charging. It is getting a little warm, but that's normal for an initial charge, and it is increasing the charge steadily. Keeping it cool on a wire rack, out of its case. I'm now gonna try to keep the charge between 25-85% as recommended for Li ion batteries.The tools in this kit are great. There's always a downside to magnetic driver tips, but still mostly helpful.Biggest challenge:For the one ribbon connection from battery to phone base, and the three ribbons from screen to base, got to use a little finesse. The connections are like miniature, almost microscopic pin-plugs (someone else said legos.) To disconnect, work with plastic prybar only, and at the "plug" itself, not the ribbon or where ribbon connects to plug. To reconnect, line it up square on the receptacle, then use light fingertip to gently wiggle until it wants to seat, then gentle pressure until it softly pops into place.45 min job in real time for me also, with magnifiers and headlight, and satisfying as hell doing fine work like that, and spending less than 5% what a new phone would cost!
