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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Battery Life *by C***T on May 10, 2022* Battery lasts very long based off of my first charge.
