    Hello, people! How are you all? Anyone who's seeing this please do reply as I am into anxiety after seeing battery health after two weeks.
    I bought brand iPhone 12 pro max on 12th December. Almost two weeks before. It was brand & was activated on 12th December & updated to latest iOS as well.
    Now what I am worried about is that I never let my iPhone fall below 50% charge. I always keep it above 60%. After just one week my battery health dropped from 100% to 99% & now in the end of second week it dropped to 98%. 2% in two weeks. Why is this happening.
    My iPhone is working all fine. No issues at all. I get 4 hours on screen time with 20% battery left but why my battery health is draining so fast like 1% every week? I live in Pakistan so here we have no authorised Apple service centres.
    Can any guide me that what to do? I am really worried.

    I don’t think you need worry too much about the 2% drop. You shouldn’t try and keep your battery over 60% charged. It is best kept at somewhere between 40 and 80%. You could always phone the Apple Helpline if you are concerned.

    I got the mini on launch week and it’s down to 97% and apple says that’s very normal.

    Lithium-Ion tend to quickly degrade at the start of their life. Then it levels out. My iPhone 11 Pro went from 100% to 95% within the first 6 months, then it stayed above 90% for the next 14 or so.

    I know that my phone is not an Apple, but what I do is on days I work, I charge to 100%. On days off, I charge to 85%. The reason is, when I am home I am on my computer, and my phone gets half to a quarter of the screen time as a workday. I also try no to let my phone go below a 50% charge. According to AccuBattery, my overall battery health is at 91% on a Pixel 3, bought on release in October of 2018.

    OP, I think @Ed7789 is correct...your battery degradation will level out soon and hold there for a while.

    You didn't mention what your battery health says now in June.

    I’m confused. Your post is dated June 4th, but you’re telling us you purchased and activated your iPhone 12 on December 12th. Unless I read it wrong, you stated that two weeks after purchasing it (around December 26th), the battery health dropped from 100% to 99%.

    You also asked why your battery health seems to drop 1% per week? If that’s true then your battery health to this point should be around 75% since it has been 25 weeks since you’ve purchased the device.

    If so, you need to contact Apple to get the battery replaced, but keep in mind that heat can have an adverse effect on the battery.

    My 11 Pro Max is almost 2 years old and the battery health is 92%. But to me, that’s just a number. Phone is still holding a charge and performing great.
