If I could give zero star or negative , I would definitely do it. Just waste of money.
The battery started to inflate after three months of using it and died within three hours while the phone is on stand by. As the battery has increased in size, the phone could not hold it anymore and has one side opening all the time. I had to change back to my old battery that worked much better. I have contacted the seller for the return, and the seller was simply sent me a returning address with no extra words explaining the returning process. Very bad shopping experience ever.

Arrived in time. Was easy to install. The tools worked OK.
I also had access to a few high grade electronics tools courtesy of co-worker – precision tweezers were very helpful.
What really helped was having a 2nd person to assist. Also a bright worklight and magnifying glasses.
Be sure to sort the screws carefully as they are removed, there are three different lengths of screw that have to replaced in exactly the right order.
I saved $$$ doing this myself, and it was fun to see inside the iPhone.

I believe the description lists this as 1550 mA-hour capacity but my phone app declares its capacity at 1700 mA-hour when fully charged. The suction cup and tools that come with the battery are handy, and the instructions are fairly good. I was able to change the battery without fully disconnecting the screen, leaving it hooked up at the top of the phone and using a small box to keep it open 45 degrees to work on the battery. The electrical connections are small and finicky - be sure you are mechanically inclined before attempting this replacement yourself. It's DIY for someone with some experience in DIY, not first-timers. The original tape holding the battery in place was very sticky and proved to be one of the more difficult tasks - prying the battery out - the best method seemed to be getting a stiff plastic tool under the battery and eventually twisting the 1/2 inch wide tool about the tool's long axis.

Not recommended. When installed the phone would randomly power down and the only way to restart was to reset the phone. I re-installed the old battery to make sure it was not some other technical issue with the phone and it worked fine. I then installed the new battery again and the shut down problems occurred again, several times. Additionally the new battery did not seem to hold its charge much longer than my old battery. After three days I gave up and am back to the old battery which amazingly is still plugging away, just. Amazon delivery was very efficient.

Je ne recommande pas de changer la batterie de cette apareil, malgré les tutorials qui paraissent simple (en 15 minutes). Les composantes et les vis sont fragiles et petites c'est une vraie chirurgie à faire. De plus la batterie d'origine est dificile à décoller meme avec utilisation d'un séchoire, nous avons utilisé un outil pour la décoller et cela a causé un gros spark! Aussi on a eu de la dificulté a faire fonctionner l'écran tactile... on a du ouvrir le cell a nouveau. Faites changer votre batterie par des pros. Sinon le kit est tel que décrit. Mais lorsqu'on réussi à installer la batterie elle ne garde pas bien sa charge.

Delivered a day early which was nice. Also nice having tools and adhesive strips included. Had it installed for over a week and battery life is excellent! Purchased a cheaper battery a year ago and ended up replacing it. This one is so much better. I also replaced batteries in my wife and daughter's iPhone with the same battery over the past 2 months and they are also performing very well.

BAD PRODUCT!!!!!!!! Cheap price and the quality is SUPER CHEAP!!!!!! Waste of money. And when I emailed the seller, they replied just return and they will replace for a new one. When I emailed them again, it says I can NO longer contact the seller. RIP-OFF!!!!! BOOOOO. This kind of sellers shouldnt even be allowed to sell stuff.....

Ordered this battery at the end of December. Install was easy thanks to youtube videos. Phone worked well for a couple of months and then the first week of February, my battery showed a capacity of 3% and that it should be replaced immediately. I used both Coconut Battery as well as Battery Life apps. My iPhone would keep shutting off after 30 seconds and kept restarting as the battery wouldn't hold a charge. I contacted Apple and made an appointment to have my defective MMOBIEL battery replaced. Now the phone works as it should.
I contacted the vendor - MMOBIEL - asking about their warranty on the battery and the response was less than desired. To quote... 'Dear Sir or Madam, If the battery works after installation there cannot be a manufacturer fault. Best regards, Menko Holding B.V. Service Team'.
I strongly suggest ordering from a different vendor or going directly to Apple for a replacement.
