Optimised battery charging - not working?

Apple just released a note with the solution to our issue !

Quote :

If Optimized Battery Charging doesn't activate

Optimized charging is designed to engage only in locations where you spend the most time, such as your home and place of work. The feature doesn't engage when your usage habits are more variable, such as when you travel. Because of this, some location settings must be enabled for Optimized Battery Charging to activate. None of the location information used for this feature is sent to Apple.

Here are a list of settings that must be enabled:

• Settings > Privacy > Location Services > Location Services.
• Settings > Privacy > Location Services > System Services > System Customization.
• Settings > Privacy > Location Services > System Services > Significant Locations > Significant Locations.

hope that can helps

I turned on significant locations the other day and that’s what got the battery optimize working. I do not think it has impacted the amount of battery my phone in any significant way

My XS Max only started working after enabling the location service settings described earlier in this thread, and then i had to patiently wait (i believe) about 7 or 8 day's for it to learn significant locations. I have noticed that it is very sensitive to when you re-charge within about an hour. So if you normally charge at 10pm, and place in on charge at 10:45pm, it probably won't work. Likewise if you put it on too early. In addition if you charge at any point outside what it thinks is your normal routine, it simply charges to 100%. It is a bit fussy, but i think the thought here is it's better to pull you phone off charge and have it be 100% than to pull it off and it's only at 80%. It seems Apple has erred on the side of caution with this feature to avoid all of the complaints they'd receive from people that the phone isn't charging to 100%. If you have all of the settings enabled and it's still not working, try clearing your Significant locations in system services, and it will re-learn - takes about 7 days.

For those of you that have it working, can you check to see if you have 'Significant Locations' turned on under Privacy>Location Services> System Services?

Apple says that needs to be on for it to work however, I don't want to have it on for the reason that I believe that would kill my battery faster throughout the day.

My wife charges her phone more than once per day and cannot get optimized charging, because phone cannot “learn” her inconsistent pattern. I charge once each 24 hour period from 9:00pm until 6:45AM, and optimized charging works for me.

Please ensure that you have enabled these location services.

Patience is the key. Can take several days to learn routine. Later iOS updates seem to have improved this feature, although notification is rare.

Yep if you charge during the day that’s likely the issue. Try to only charge at night before going to bed preferably around the same time each night.

Hey, mruprai.

I see that you're worried that Optimsed Battery Charging on your iPhone 11 isn't working as expected since it’s fully charged in the middle of the night, and I'm glad to help.

About Optimized Battery Charging on your iPhone -- Go to Settings > Battery > Battery Health and make sure the feature is on. When Optimized Battery Charging is on, you should also see a notification on the lock screen when your iPhone will be fully charged.

Let me know how that goes, and take care!

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

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%.

iPhone X and same here, does nothing, goes straight to 100% as if the feature doesn’t exist. I’d also like point out how utterly useless and pointless it is to just post saying people should check it’s switched on, seriously?
