As many of them may be knowing about iphone. and its battery health option.. one can know the health of its battery. a new purchased phone shows 100% battery health and as the time goes. the charging cycle and usage of phone. and phone drops. the battery health goes downs even suggests what to do to sustain battery health.
i would simply tell i am having s21 ultra when i purchased when i leave i morning at 100% battery. i would still have 20 to 30% battery. but now i have to charge the phone in evening or there might be last 5 to10 % left. phone usage is same. but battery health has gone down
