    I always charge to 79-80%. I had been using the included 5 watt charger, but it was designed to use with the dinky iPhone 4 battery which is half the size of the Plus size batteries, so I recently started using the iPad charger. I just don't have patience any more for that little 5 watt charger. It's a time waster. The iPad charger WILL heat up the battery a little more while charging below 80% because it dumps in a lot more current: 7+ watts. So it's not a good choice if the ambient temperature is hot - hot day.

    If I'm charging the phone unattended, I sometimes use the app Charge Alarm Pro

    https://itunes.apple.com/us/app/charge-alarm-pro/id1071191623?mt=8

    especially now with the iPad charger because that charger charges much faster... The app will alert me to unplug.

    It will sound an alarm when the battery charge hits your set point (any percentage you choose) but it has to be kept in the foreground to work.


    I had an old iPhone 5 I used to use years ago (still have it in a drawer) that I used to use plugged in all the time - keeping it at 100% all the time - and the battery swelled and lifted the screen. So I don't recommend doing that ever.

    Isn't this too much effort for just charging a phone? What if you are outside and those 40% between 80 and 40 are not enough for you? This way you are using all the time less than a half of the battery's capacity...

    Thank you for the post. I was exactly like you up until very recently. Always charging 40-80% and afraid to ever let my phone get too hot. I had multiple battery apps and even a battery temperature app with a warning when it got over a certain temp. This was on android, so none of it will work on iOS.

    I would baby my phone and then end up selling it within a year. I had battery cases and portable chargers “just in case” I was out and my battery fell too low. I could have avoided that by charging to 100%, but I was hell bent on not losing any capacity.

    Let me tell you, it feels great to be free of all of that. A new battery at full price is like $80. That is only a few hours worth of pay for most people. Why are some of us wired to be battery ocd. I can understand heavy users having ocd about their phone dying, but people like us who are terrified to lose capacity are equally as frustrating.

    It took a week or 2, but I got over my battery ocd and just charge my 8 plus to 100% every day. I don’t need to, since I use 35-45% per day. I could go 40-80% if I wanted to, but it’s just silly. I wish you the best, but you’re fighting a losing battle.

    Having the phone always between 40-80% and avoiding charging to 100% or letting it die is ideal, but come on people. It's a phone. Don't change your life by setting alarms to stop what you're doing to unplug your phone, or turning your phone off because it hits 40%. A lot of engineering going into the charging process of your phone to minimize any harmful impact by keeping it plugged in or using it until it dies.

    By only charging it to 80% and never letting it get below a certain percentage you're effectively removing 20%+ of your battery capacity to begin with, which is exactly what you're trying to avoid in the first place...

    All good points. My take on the matter is... IF the battery can be recharged before it drops below 40% and unplugged near 80% without too much trouble....doing so will increase its life span.

    But IF the phone will be away from power all day and carrying a battery pack isn't desired and the phone will likely need all the battery capacity it can get to make it through the day....definitely charge it up to 100%.

    You qualify if you want it since there is no requirement for the battery to be in any particular state for this program this year.

    This proves the battery health info is not accurate at all. No way in hell can any battery produced in late 2016 still be at 100%. Not even if they left it in a box without being used.

    Not true. The (beta) battery health monitor in iOS 11.3 compares the performance of the installed battery against the battery specification... Not against the actual battery when it was new. Not all batteries are created equal. Some leave the factory with a larger real world capacity than the specification.
    If that battery has a 3% greater capacity than the specification, there's no way for iOS to know that. It could degrade 3% and iOS would still see it as having 100% capacity.

    His phone is 1.5 years old. An iphone battery is rated to be at 80% after 500 cycles. Figure that's 2 years for most people. 10% loss per year, give or take. Let's say he's a light user. He would still be below 100%, even if the battery came at something like 107%.

    I know it's in beta, but I've seen people with 400+ cycles on here still showing 100%. A battery that is unused on a shelf will lose several % per year. I'm a battery rube, but this info provided by ios 11.3 is worthless as far as I'm concerned. No battery in any phone can stay at or near 100% after 18 months on a shelf, much less heavy use. I'll wait for it to go out of beta before putting any stock in it.

    idk whether or not the info is accurate or not, not sure what program can be used to check it, I remember there is one, but forget the name of it to check Apple devices battery health.

    Thanks, I finally remembered it after posting the reply. Coconut Battery says 100% as well, with only 52 cycle count, says phone was made on Sept 12 2016, 578 days old.

    14 months old 7+ on 86%.

    Is it bad for a 14 months old phone?

    A family members iPhone 6 from march 2015 is at 94%. Hard to believe as she is the sort of person to charge it twice a day with every location services item toggled etc. Phone looks like it came out on the losing end of a fight with a dog as well haha.
