Optimised battery charging - not working?

For me, there has been some change - both my IOS phones now do sometimes use the optimised charging.

It seems pretty random though - some nights it works, other nights it doesn't. Some nights only one device does it and the other not, other night vice versa.

Guys my advice, don’t do anything don’t turn off location or background etc it’s random to work, my phone (have never touched locations etc) after the 13.2 the first night worked after the next night it stopped and now the last two nights it’s working...

Optimized battery charging is still not working for me on an iPhone 8 Plus and iOS13.2. It goes right to 100%. I’ve never seen the notice on my lock screen.

I’ve already tried different scenarios, such as turning off my night schedule and try it with alarm only, I’ve tried to charge it from different levels of battery and I’ve tried to keep my schedule same for a week (only charging it from around 00:00 to 6:30 in the morning). Nothing helped. The same goes for my friend and his iPhone 8.

Would appreciate if Apple fixes this.

It’s from an older date, but this is what I see almost every morning since the function is on:

Optimized battery worked for me the very first time I charged my iPhone 11Pro. Since then, it never worked again. Very frustrating and I don’t get why Apple doesn’t address this issue through a software update.

I've never gotten this function to work either, just goes straight up to 100% for over a month. Wake up at like 6-7 am. I'm using an iPhone XR and a wireless Qi-certified charger. Does anyone know if it works with wireless chargers or not?

Will try a wired charger instead for a week and see if anything happens.

Agreed - I have an XR and have done absolutely everything and made all the adjustments recommended in the Community as well as by the Support person with absolutely no change in the charging <it goes right up to 100%>. My charging schedule is very consistent. The only other thing Apple recommended <which I'm not willing to do> is a complete reinstall. It's a great idea and hopefully will be operational in a future release but right now seems more of a dream than reality!

Update - both my phones are now working more often than not with optimised battery charging, although one of them seems to go from 80% to 100% about 2 hours earlier than it really needs to based on my getting up time.

There are some nights when it doesn't kick in, but I'd say the majority of nights it's now working.

It's never worked on my iPhone XR. I've tried all the suggestions of and it's never worked when I'd initially installed ios 13 or 13.2.2! It sounds like a great idea and it seems to be one of the signature items that Apple has been promoting but I feel like I'm out of options until there's some sort of fix maybe in 13.2.3!!

I have an iPhone 8 and this feature has never worked for me at all. I updated to iOS 13 on day of launch and have the setting switched on. Like alot of people I charge my phone during the night, I can’t believe nobody at Apple thought about incorporating optimised battery charging linked with the alarm. That way the iPhone knows when it has to finish its charge cycle instead of having to try and learn when you charge your phone and get it wrong 🤔

This feature still does not work for me right from day 1 when ios13 launched and I have followed what other people have done to make their phoned work with this feature. It’s so frustrating I am unable to use this feature even when I have upgraded from an iPhone 8 to iPhone XR. I think Apple have tried to be to clever and should of kept this so simple in my opinion, most people charge their phones at night so why not use the alarm as the mechanism of when to charge to 80% and stop and then carry on when it knows when you are going to wake up.

I have an iPhone XR and have done everything thing per all the suggestions and it's never worked for me. I have a very routine schedule and initiate charging at the same time each nite and it simply charges right up to 100%! Hopefully ios 13.4 comes soon with this fixed!

Hello, i have the 11 Pro Max and i charge my phone every night from the moment i fall asleep at around 12, until i wake up at 7am. the optimized battery setting is on, and my phone is supposed to charge to 80% and stay there, but it always goes to 100%. Maybe apple does that on purpose to degrade new batteries faster? Or is it just a software bug? If so please fix this as fast as you can. I payed 1300€ for this iPhone and as a premium product i expect it to function properly. Thanks!

*note that location services, system customization, significant locations are ALL turn on and the feature is still not working...

i also charge my phone at the same place and time every night, and all the location services options stated above have been turned on since time of purchase (over 2 months ago). I proceeded to turn them off and back on but after a week it’s still not working

Hmmmm - my old 6S is working fine most nights with this.

My XS Max didn't work at first, then it worked about 80% of nights for a month or two, but since last week it's stopped again.

All the options about location etc mentioned above are on.

I tried various experiments, like closing all apps before putting on charge, and even rebooting the phone before going to bed each night, but I haven't been able to find any pattern to why it works sometimes and other times not.

I would say that the XS Max has a lot more apps on it than the 6S, and I would hazard that there is some app or combination of apps that is interfering with this capability, but it would be very time consuming to try to figure out which one(s)

first off, try not to sound so entitled next time. second off, I agree, there should be a way of setting it yourself, but Apple are pushing for a fully automated future where your phone does everything for you. Third off, the SE is very old and is the oldest iPhone to be using iOS 13, many features won’t work as well on it as they do on newer devices. I go to bed at or around 11PM or 12AM everyday, and my optimised battery charging works. I wake up inconsistently, at around 8AM to 10AM, and it still works. I also want to point out that if you’re using the SE, new software is going to kill the battery. If you have an older iPhone, when updating, it’s better to back your phone up, factory reset it, then install the latest software, because otherwise you’re just stacking the new software on top of the old. iOS 13 has proven to be far less battery draining for me and everyone I know who uses iPhone, and the charging optimisation feature works for most people. If your sleeping pattern or charging patterns are irregular, just turn the feature off. It’s designed to prolong your battery life, but if you’re using an SE, there’s little point in trying to save it when it’s going to become obsolete in a few months. I know it’s not as simple as buying a new iPhone, they’re not cheap, but if you’re going to use an older model, get used to things not working so smoothly
