How can a used phone have 100% battery health ? Was it serviced ?
It could’ve been a replacement or the device was just not heavily used. My SE3 battery health, which I’ve had for a year and half now is at 99%. Granted I don’t use it heavily (mainly work email and chats) so it only gets charged 2-3 times a week. So it’s entirely possible there are 100% battery health SE3’s out there on the used market.
 
Seller said it was used for about 50 calls then put in the draw for a year.
That could make sense

You probably have a lucky battery, slightly better than average (the 100% is relative to average… you could be like 102-103% when new), so the low usage and recharge cycles count did the trick.
