Review: You may have to improvise - I would rate the skills needed to remove the old battery and install this new one as “proficient/advanced” and the task itself as 6/10 for difficulty, only because you may have to improvise if it doesn’t go according to plan. It took me a little more than an hour after I watched a YouTube video tutorial and read the included instructions. Some of the steps and some of the photos in the instructions are not clear so you really need to watch a good video. The two hardest tasks are 1) opening the phone, and 2) releasing the old battery. It was hard to use the suction cup, squeeze the sides of the phone AND wedge in the metal piece, all at the same time. The metal ring on the suction cup is useless because it’s a thin gauge wire and it opens when you pull on it. I ended up just squeezing the sides of the phone and wedging the metal piece into the bottom seam. I scuffed the phone slightly but you can’t see it once I finished and put on my protective case again. Removing the four adhesive tabs did not happen as shown in the video. I worked very, very slowly and all four still tore, leaving the adhesive on the back of the battery, still securing it to the phone, so I had to pry up the battery. The blue plastic pry tool (included) was useless and broke immediately. If you need to pry up the battery, you may need something that’s made out of sturdy plastic or wood and is very thin, like a clay sculpting tool. You might be able to use a metal flathead screwdriver if you put tape around it. It can be difficult to pry up the battery because there’s nothing to use as a leverage—you don’t want to damage any internal phone components, you don’t want to bend the metal casing, and you don’t want to puncture the lithium ion battery. If you have any doubt that you won’t be able to find a safe way to pull up the old battery if the adhesive tabs tear, then I wouldn’t try this installation. I’d have an Apple tech do it. As far as the battery charge: I charged it to 100% and after an hour of just reading articles and some light texting, it’s down to 92%. So far, I’m satisfied with this product.
Review: If you're going to replace your own iPhone 8 battery, buy this one. - I've installed quite a few batteries over the years but the iPhone 8 battery is not as easy as most. I used the iFixit guide which is very well written and concise albeit not for the first timer. There are many places in which a mistake will cause you a whole lot of hurt. Be careful and take your time. This battery kit is almost perfect except it is missing the "standoff" screwdriver. I used a very flat flat-head screwdriver that worked but it slipped easily which caused the blade to come dangerously close to stuff that could be damaged. It would have been nice if this screwdriver was included but for $18, I can't complain. The adhesive seemed to fit pretty well although was not very wide on the sides. I don't know if this is the way it is supposed to be or was just a inferior product. No way to check how good the water proof seal is. To conclude, this kit is perfect if you want to replace your own battery on an iPhone 8. Very pleased.

## Questions & Answers

**Q: Does the battery chip data need to be copied from the original battery to the new battery?**
A: Dear friend, replacing the battery will not affect the data of the mobile phone, but it is recommended that you back up the data of the mobile phone before the operation to avoid data loss due to accidental damage to any accessories during the operation.

**Q: how long does the charge last on this battery?**
A: Dear friend, the battery life after charging is related to the performance of the battery, as well as the health of the motherboard of the mobile phone and the usage habits of buyers.

**Q: Does the battery include genuine parts? I’d like it to not have the error message, “unkown part”**
A: Because the IOS system has undergone special encryption processing, resulting in the motherboard can not identify the non-original battery chip, and issue a pop-up window prompt. Please do not worry, this will not affect the normal use of the battery. The pop-up prompt will disappear after about 1-2 weeks. If you don't want pop-ups, you can change the date from automatic setting to manual setting, set the date 2 years ahead, then turn off and restart, then there will be no pop-ups, and then set the date back to automatic setting.

**Q: Does this include the replacement waterproof seal?**
A: The repair kit included the frame seal adhesive, but I recommend that you use B-7000 glue. B-7000 glue is professionally used for the bonding of electronic instruments. It has a better sealing effect and can retain part of the waterproof function of the mobile phone. The price of a small dose is about 5 US dollars. Since battery are dangerous goods, B-7000 glue is also dangerous goods, so our replacement battery repair kit cannot contain both battery and B-7000 glue, otherwise it will cause great restrictions on logistics and transportation, I hope you can understand! Have a great day!
