Optimised battery charging - not working?

It is not working on my 11 pro running on 13.2. I talked to Apple support. Apparently there is no entry on their end of this issue. So perhaps report directly if the issue continues. Support told me that after every iOS update it will basically reset and it takes 5 days until the phone learns the charge pattern again. So this could be the issue. I am skeptical if this is the issue here, but will monitor. I asked to open a case anyway, so they can check. Again, if you continue to see this issue, let them know.

This morning I had a notification that optimised charging has been enabled. I have been following this thread since iOS 13 was released and this is the first time it has worked on me Xr. 5 days ago I disabled optimised charging permanently and had since forgotten about it. This morning I received the notification that it had been enabled automatically, so I checked the battery in settings and it had worked. It remains to be seen if it will continue to work, but I suggest turning it off in settings if it has never worked for you and give it a week. Not quite a solution, but a possible workaround.

Finally works (sort of). I enabled all of the privacy settings last Monday (1/13). This morning I noticed the message about optimized charging. However looking at the battery info charging resumed at about midnight we’ll short of when I get up. Maybe it takes a little while longer to learn. If you’re still waiting for yours to kick in plan at least 5-7 days after enabling the appropriate settings.

done a tonne of testing and found that it literally works if you charge your phone around the same time each night, charging randomly during the day will throw it off as it’s machine learning, it’s not like teaching a living thing. mines been working for weeks, because at 11PM (ish) i put my phone on my charging pad. so long as it’s within the hour that you normally charge it, it should work. taking it off charge too early will also throw it off. As far as i can tell, location doesn’t affect it, but i don’t travel much so i don’t know for sure. if your routine changes, then it has to re-learn, but it should only take a few days. the feature is designed for people with solid sleeping patterns, but if you just put your phone on charge at the same time each night, going to sleep or not, it should work

Support said it takes ab 5 days to learn your schedule , so if you clear the memory, you cleared out the learning

Unless you are up in the middle of the night watching it you won't know when it goes to 100%. If you charge overnight it should always be at 100% in the morning. Optimized charging just controls when it reaches 100%.

It only shows the time when 100% charged will be on your lock screen while it is in optimized charging mode (80%). So, to see it (if you need to), touch your screen after it has achieved 80%.

I have an iphone xr that is about 7 months old. Im on ios 13.1.2. My battery health is still at 100%. My optimize battery thing is toggled on. I have a fairly regular schedule. I plug my phone in at bed time sometime around 10pm ish and unplug in the morning around 6:30am. I check the graph regularly and my phone always reaches 100% within a few hours of plugging it in, usually around 12-1am, and it in and stays there until I unplug it in the morning. Ive never had a notification pop up about the battery being optimized. From my understanding it uses machine learning to figure out when not to fully charge it but its been weeks now with no apparent "optimizing" happening. This is the 3 bug/feature not working ive encountered since updating to ios13. Im rather disappointed in apple right now.

I don’t know you guys but iOS 13.2 seems to have fixed that issue on my XS.

Now the charge stop at 80% !! Finally, was waiting for that since iOS 13 beta.

let us know if that update fix your issue too.

Worked for me yesterday for the first time!! iPhone 11 here... I updated on Monday to iOS 13.2. That night it didn't work =(. However, today I checked the battery graph on settings for last night and it worked!

It stopped charging at 80% around 1am then at around 4am it started to charge again until 5am when it reached 100%. I always put it out of the charger at around 7:30am, so I think it still needs to improve its predictive algorithm, but al least it worked.

PD: it didn't show the alert when I put the phone on the charger, so I just realised that it worked by looking the graph below.

PD2: I have background activity active.

this features works for me now now, I to had grow frustrated with this feature never worked for me at all since it’s launch. about a month ago I reported it and spoke to someone. I had to upload 2 lots of information from the phone 1 of the phone itself and 1 of the battery so the engineers could look at the data. The chap I spoke to acknowledge all the settings was correct on the phone and really wanted to know about my routine with how I charged the phone. The next night I get a message on the phone telling me battery optimisation was on and has worked every night for me. I’m not sure if the uploads have done something to enable this but the above might work for you.

I’ve only seen it once, but then I’m not awake when it usually reaches 80%. But, it has regularly performed optimized charging for each night over the past month or so. I know it won’t work if you also charge the phone for a while during the day. I think it has to occur over one, regular complete charge.

It started working again after I shut it off for one day, then turned it back on. Go figure!🤷🏻‍♀️

That usually works. I have also found you need to shut off for a day after each update. Seems it needs to reset itself after each one.

I think it would since the battery optimize uses location services to work properly.
