I need help understanding this. I got my phone last May and 2 months later which is today, my battery health decreased to 99%. I just want to know what’s going on? Can somebody help me understand or maybe you guys have any idea on this one and is there something I should do?
What's going on is physics. Rechargeable batteries lose capacity as you use them. There is no way to stop that and very little you can do to affect the rate at which the maximum capacity decreases. You should expect to see a loss of about 1% a month on average. There is also pretty much zero% reason to even look at the battery capacity unless 1) you're having a problem with your phone or 2) you're nearing the end of the warranty period. Apple considers the battery fit for use as long as it's over 80%.

Sorry about that. I get the part about physics. Appreciate that a lot. I am just a bit concerned coz I just switched from android to iphone and I am really not familiar how these phones work coz android phones don’t tell you that. Also, my phone easily drains and I happen to charge it twice a day. Any advise on how I can maximize battery life? Thanks.
Thank you
Hope it helps!
