Does the battery chip data need to be copied from the original battery to the new battery?

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.

how long does the charge last on this battery?

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.

Does the battery include genuine parts? I’d like it to not have the error message, “unkown part”

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.

Does this include the replacement waterproof seal?

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!
