    Why is my iPhone XS from release day already down 2% of it’s battery health? My iPhone X was 99% after 1 year and a few months.

    Reason to worry?

    Thanks in advance.

    I would say yes... thats a concern. Its only been out for a few weeks and you lost 2% of your battery.

    As random155 pointed out, that is reason to worry. I recommend a trip (back) to the Apple Store...

    You have no reason to be concerned. Forget about it and just get to using your phone. If I gave you a can of beer and it was 98% full, you'd never even notice. First, that number isn't significant in a stand-alone way. It's only useful as a trend indicator over time. Second, batteries don't age linearly. Just because you see 98% now doesn't mean you'll mean see 96% in two weeks, 94% in four weeks, etc. Go to Apple if you want to but it'll be wasted trip.

    It's nothing to worry about. Batteries need a certain number of charge cycles before it reaches its maximum capacity. I personally don't trust that rating, it's not absolute.

    For now, I wouldn't worry about this. I would keep track of the progress though to see if this is a trend or not. If it keeps dropping over a short period of time, then you could always drop by the Apple Store. However, they only warranty the battery when it gets below 80% in the first year. As others have said, the battery will not deplete linearly so you have to give it more time to see what the trend is.

    I'm at 99% too. This did not happen to my iPhone X. Maybe it's a defective unit?

    I wouldn't panic about 1-2%, it's chemistry and battery life may vary by these 1-2% depending on several factors. Get Coconut or iMazing to check actual battery health and charge cycles. If it will drop by 1% every 10-15 cycles - it's a faulty battery and you need to replace it.

    And always check battery health at 100% charge.

    No panic :) Batteries aren't identical, capacity may vary for about 2-3% and it will be OK. Check the battery health at 60-70 cycles. It should be around 99-98%.

    I would say there is no reason to be concerned. This is probably due to your charging behavior and usage on the device. However, my device is showing 105% of designed capacity somehow lol Use your device as normal, keep the heat down and keep the charge on device between 15-85% to minimize the stress on the battery being too low or too high.

    I also have this problem and contacted Apple about it.
    They told me to send it for repair, which is horrible.
    I accepted the offer, but I think it’s unacceptable to replace the battery of a 25-day old phone. I do expect them to send a replacement unit.

    We don't have apple stores here in my country, only premium resellers, so to make them understand my battery have issues is a mess, and sending it under warranty means like a month without phone... but i never had a battery issue like this, my iPhone 8 was used for 11 months and have 91% of battery capacity, i don't know what to do... maybe just deal with it... unless it goes even lower :/

    My iPhone X was down to 92 % battery health after less than one year. Normal usage, no gaming or other hard tasks. No heat or freezing temperatures. Charging over night as usual. I haven't had any problems making it through the day and wouldn't consider 98-99 % a problem, even on a new phone.

    THAT DEPENDS ON HOW MANY TIMES A DAY YOU CHARGE YOUR PHONE AND IF YOU LET YOUR PHONE GO WAY DOWN TO ZERO AND CHARGE AGAIN

    Actually im talking to apple through support chat, they say it's not normal to decrease so fast in less than 15 days so they will make a report if it persists, to send it through warranty :'(

    Reading this thread led me to check my own and mi wife's iPhone Xs Max phones and both of them are 100% - whew!

    I'm curious - those who are mentioning how many cycles their batteries have - how do you know this?

    Use Coconut Battery, iMazing or some iTunes alternative that can provide battery stats from iTunes backup.

    Just a weird update, using coconutBattery at that time it showed 97.2% of total battery capacity... today i tried it again and the battery capacity now is 99.2%... it's normal that coconutBattery give that sudden change? it should be lower not higher xD it's weird but anyway i'm kinda relieved

    PD: Battery capacity on iPhone still shows 98%
