Battery replacment, do you need tag on flex?

@e_ahh Yes, the tag-on is designed to be installed inside the phone and left on permanently, or at least until the next time you need to replace the battery.

Hey Jacob Lund, thanks for your comment.

So if no tag-on-flex is needed for SE2020, how does Battery Health get reset to 100% ?

@eladbrab You have to use a device programmer. The most popular kinds are the JC V1SE or the QianLi iCopy. Figure around $85 USD new for one or the other. There are newer devices made just for batteries that may be cheaper.

Sorry, this is not true. No tag-on flex is needed for XS/XR/SE2020. Only for 11 and up in my experience — Jacob Lund
Do you need to keep the tag-on flex connected after the health is corrected? — Ethan Leroux
