When you do the initial setup it asks if you’d like to optimize for battery health and most people say yes. Most recently it wouldn’t even tell you that it was only charging to 80%.It would still charge to a hundred but that would actually be eighty percent. Around a year ago they changed it so now it says eighty percent when you’re at full charge if you have the battery health turned on.

If you turn on the battery over provisioning you would see the same battery life at about a year and a half and then after that the provision battery will last longer. After the exploding phone they also provisioned five percent of all batteries.

Samsung encourages battery provisioning in it by the user. So most people using a samsung only charge to eighty percent.
