iFixitBattery Compatible with iPhone 7 Plus - Repair Kit

Works fine. I find these kinds of battery installs pretty routine and could do without the tools, but I got this kit because it came with the adhesive gasket and the reviews seemed strong. It seems to be good. It snapped back together the way it should and sealed well. As for battery life, it seems good. It gave the phone new life, and seems to last well, at least until my mom finally decided to upgrade.

Overall, this was a pretty easy repair. You can watch the ifixit video which is helpful. I watched a few videos from various people on YouTube and each one gave a few extra things that helped. I didn’t heat the seal with anything special, I just used a blow dryer for about a minute. Not totally sure if it was even necessary. Once you start popping up the screen, the very top is locked in, you have to slightly slide it down before the top will pop up. At reassembly, I would recommend watching an ifixit video that’s specifically on the seal. The seal/gasket goes on the battery side of the phone not the screen side. When putting the screen back on, you start a little lower and then slide the top back in first. After the top is in, the rest of the screen snaps in no problem. I’m extremely happy with the purchase. The phone now shows the battery capacity is at 100% and the phone works so much better.

This ifixit battery kit for my iPhone 7plus did the trick and it is a very high quality repair kit and battery. After a week of use with the new battery, my phone is lasting a whole day of regular use and still has 20-30% left at the end of the day. I’ve had my iPhone 7plus since 2016 and the battery wouldn’t last more than 6 hours with the lightest use. My phone battery health said to change it so I bought this kit and changed the battery myself at home. This kit had everything I needed except for a hair dryer to heat the adhesive. Ifixit had a repair article online to follow plus there are many videos to help as well from other sources. I have a little experience with replacing iPhone internal parts but I haven’t done it since the iPhone 5 came out so I wasn’t sure how but this kit and the online repair article were exactly what I needed. My battery health now says 100% and I can easily get a full day of use out of my 7+ year old iPhone 7plus.

One day my iPhone would charge to 100% but when I disconnected it from the charger, the battery level would drop to 1% (that's not a typo) within 5 minutes. When it was connected to a charger it was pretty much useful (other than being tethered to something not particularly mobile), but it would periodically reboot itself.The battery included with the iPhone 7 Plus is rated at 2900mAh capacity, but there are there are outfits selling replacements that they claim are 4000, 5000, or even 10000 mAh. I don't believe them - the battery would need to be considerably larger than would fit inside the phone. So I avoided those and went with iFixit, a trusted brand that didn't make bogus claims about the battery capacity.Replacing the battery isn't rocket science, but it does require quite a bit of care and detail. Before you buy, read iFixit's documentation on how to replace the battery and watch their video. Read the comments that other people have left on the instruction steps - they have incredibly helpful information and tips. Watch a couple or a few other videos on youtube. Then if it looks like something you want to try, buy this kit which includes pretty much everything you need except a hair dryer to loosen the adhesive between the phone's display and the phone's body; and some pennies and books to help seal the display when you've finally closed up the phone after replacing the battery.In my opinion one of the most important things is to have is somewhere to safely store the various screws you need to remove. They are nearly microscopic - about the size of the head of a pin - and are different sizes. You need to put the right ones back in the right place or you are screwed. I had 8 little plastic jars (like might hold cosmetics) - one or two for each step that screws were removed (2 jars when there were different sizes involved in a step). Each of the jars was labeled and had screw on lids so even if I knocked something over and sent things flying I'd be able to collect all the jars knowing that the screws were secure.After doing the replacement my iPhone is good as new. I've had it for about 8 years so far and it still does what I need it to do so $25 for a new battery that should get me at least another 5 years is great!Just for reference this iFixit iPhone 7 Plus battery replacement kit was $24 (Oct 2024).The photos show my "screw management system" and the iFixit kit (along with my screw management system) but without the battery and the display adhesive component since they are inside my phone.

Worked OK for about a month. After that it gradually got worse at holding a charge. Now at 2 months of age, this replacement battery can't even hold a charge for half a day. Waste of money.

However battery is not very good. New battery life is about the same as the old without the plummeting levels of the old. So yeah, consistent drain, reliable estimated life, but doesn't come close to the two day use a new phone battery should have. Must recharge before end of day. So, not much of an improvement.
