My launch day 11 Pro finally got to work. My sleeping schedule is unpredictable except for the weekends so wouldn’t quite put the blame on the iPhone. But I’m quite surprised to see that it finally started working. I got AC+ so never really thought about taking care of the battery much.

Has also worked for me since the last update. Even if the battery level is 85% when I plug in the iphone in the evening, the device does not charge fully, but only up to a maximum of 90%. I can also charge as much as I want during the day. Only the weekends are not taken into account. Even on Saturdays and Sundays, when I normally sleep longer, the device is fully charged at 6 a.m.

I have no idea how this optimised charging works. I tend to just never let the battery reach zero and the phone turn completely off before charging, but when I plug the phone in at night it always charges to 100% (I have an iPhone XS). If I ever top up during the day, when the phone gets to 80% it gives me a notification saying the phone is sufficiently charged but if I ignore it, it still charges past 80% to the full 100%.

Should I take it off charge at 80% when the notification comes through? I really have no idea how to utilise optimised charging and even the YouTube videos and guides I’ve read don’t seem to match up to my ownuse and charging habits/experience.

First off, using your phone till it dies or reaches 0% is bad for lithium ion. Try to keep it >20% if you can.

Optimized charging works only when you charge your phone the same way all the time - and leave it on the charger for long periods of time. If you do this, then it will only charge to 80% and then hold it there until an hour or two before you usually unplug it, then charge it to full.

The idea is that keeping a Lithium Ion battery between 20-80% extends the life significantly.

If you’re like me and plug your phone to charge all the time (my car, work, home, etc) - optimized charging will never turn on. :p

Well, I charge at work, in my car, at home during the day. I just make sure that the battery level does not exceed 80% in the evening. And optimized charging is still working. With one exception: charging after midnight prevents optimized charging for me.

When the phone shuts off from "dead" battery, the battery isnt dead. It just doesnt have the power to properly power the device, its a big difference between that kind of "dead", and actual flat dead (where the battery icon screen cant even display, or even beyond that, and the duration it stays in that state if its to reach it in the first place).

Yeah, I never let this iPhone drain to 0% and then power off. When I get the 10% left warning I stick it on charge. I took my XS off charge at 04:23am on Monday morning and didn’t put it back on charge until 18:40pm on Monday evening.

I woke up at 03:40am with my wee one this morning and took it off charge at 100%, it’s now 08:50am and I’m on 93%.

So if I wake up early enough I’ll take it off charge rather than leave it on the charger at 100% until I wake up at 7am for work.

There's just so much conflicting opinions out there when it comes to leaving your phone plugged in when it’s hit 100% ... some say it’s bad for the battery to have even a small current trickle into it when it’s fully charged, while some say it’s absolutely fine to do so and that the battery isn’t impacted by being left plugged in while at 100%

I smashed my XR a couple of months ago in a drop, and my battery health on that was 91% after a year as I’d often let it run down to 0%, put it on charge for a while, take it off at 30-40% and run it down to 0% ... bad habit I know.

I got this XS two weeks ago, so want to optimise the battery health better than I did with my XR!

I'm also having the same issues with bad sleeping habits, but I have not yet tried this. Let me try this out and share my feedback again.
