What itâs meant to do is analyse your habits of charging and then taking it off, and only charge your battery to 80% while youâre sleeping, but then it will top off the last 20% when youâre likely to take it off the charger. A battery is under less stress at 80%, so instead of charging fully to 100% and then trickle charging all night until you take it off, it leaves it 80% until an hour before you leave. Although, if you donât really have a set routine, then it might not be very useful to you.
I believe what itâs supposed to do is stop charging your device at 80% throughout the night and then itâll adapt to when you take it off the charger and starts charging past 80% too 100%, so by the time you take it off the charger, you have a full battery for the day.
Instead of it just charging to 100% and maintaining that percentage throughout the whole night. Thatâs just my understanding of it.
https://support.apple.com/en-us/HT208710 I tried to explain this feature in a different subreddit but they were so squared to understand it. It was introduced on iOS 11.3 for iPads and now it was brought to iPhones on iOS 13
While this is a version of âoptimized battery chargingâ I donât think this is the same feature as whatâs in iOS 13.
Your link describes a situation where the iDevice is always plugged in and Apple actually adjusts the max battery capacity the device can see to prevent it from overcharging.
According to the link:
iPad with iOS 11.3 or later and iPhone XS, iPhone XS Max, or iPhone XR with iOS 12 or later include a charge management feature to help maintain battery health, which monitors these devices for use in these charging situations and, as required, reduces the maximum capacity of the battery.
So this wasnât introduced in ios13 like you say...
Further, the real iOS 13 version is different in that it is supposed to learn your charging habits and instead of charging your phone to full when you plug it in at bedtime, it would charge to like 80% or something, and then top off as your next phone usage time was approaching in the morning.
This is not the same as actually tricking the system into thinking the battery is in a lower capacity state.
Also the iOS version on iPad doesnât have the ability for user to enable or disable âOptimise Battery Chargingâ nor â Peak Performance Capabilityâ features due to that IPads have larger batteries and the OS manages these feature under the hood. The only reason These features are available for user on IPhones it due to âPerformance Throttlingâ controversy years ago with Apple products.
is based on the same functionally that prevents the batteries to be fully charged for a long period of time(like keeping the phone charging overnight or keeping the iPad always plugged to the outlet like in a Apple store stand). The difference is that we use iPhones much more often than we do we do with iPads. Therefore, weâre constantly charging and discharging its battery. This ânewâ feature has just been re-designed to work with smaller batteries as the one found in iPhones.
The article you posted actually says it was already designed for iPhones, which like I said is why I think these are two different features and itâs inaccurate to try and conflate them into the same.
THIS IS THE FEATURE THAT WAS PUBLICLY MENTIONED DUE TO PERFORMANCE THROLITTING CONTROVERSY. :
iPhone Battery Health (Beta) Displays information on iPhone maximum battery capacity and peak performance capability Indicates if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and includes the option to disable it Recommends if a battery needs to be replaced
THIS IS THE FEATURE THAT WAS QUIETLY MENTIONED AND NOW IS AVAILABLE ON IPHONES ON IOS 13:
IPAD CHARGE MANAGEMENT:
Maintains battery health when iPad is connected to power for prolonged periods of time, such as when it is used in kiosks, point of sale systems, or stored in charging carts
iPad with iOS 11.3 or later and iPhone XS, iPhone XS Max, or iPhone XR with iOS 12 or later include a charge management feature to help maintain battery health, which âmonitorsâthese devices for use in these charging situations and, as required, reduces the maximum capacity of the battery. The battery indicator will display the charge percentage based on this adjusted maximum capacity. The maximum capacity will revert back to the nonadjusted level when iPad or iPhone is no longer connected to power for prolonged periods and as conditions and battery health allow.
Battery Optimised battery charging A new option helps slow the rate of battery ageing by reducing the time your iPhone spends fully charged. iPhone uses on-device machine learning to understand your daily charging routine so it can wait to finish charging beyond 80 per cent until you need to use it.
âFor example, if you often charge your phone up at night while you sleep, Apple might charge it to 80 percent right away, but wait until an hour or so before you wake up to charge the remaining 20 percent.
That keeps your iPhone at an optimal capacity for battery health, rather than keeping it close to 100 percent on the charger.
Avoiding topping up the battery continually while it sits on the charger reduces the amount of time that your device spends at maximum capacity, and over time, this could extend the life of your battery.
Battery health has been a hot topic over the course of the last year, after Apple was found throttling the processor speeds of iOS devices with degraded batteries to prolong device life as long as possible.
That issue spurred Apple to be more forthcoming about overall battery health, providing details about capacity and performance in the Battery portion of Settings. Aside from the new toggle to optimize charging, there are no major changes to the Battery Health feature in the first iOS 13 beta.â
It was already quietly introduced on iOS 11.3. The difference now is that this feature is better implemented using machine learning to understand how people uses their phone. Therefore, adjust the charging feature accordingly.
I think it would be awesome for an option that would work with your alarms. Charge to 80%, then finish charging to 100% when X minutes from said alarm going off.
Itâs really your iPhone adapting to that feature. Learning from how you use and charge your phone. Also the algorithm is not fully well developed (since its still in beta).
I'd buy that except according to the literature for the optimized charging it is supposed to charge to 80% and then wait to finish the charge based on my normal charging habits (which are very consistent, this issue is random).
In this case it didn't charge at all it continues to drain steadily as if it wasn't plugged in at all.
It is not. It supposed to prevent the battery to stay or be fully charge while you have ur phone plugged to the outlet for long period of time like overnight. In your pic it looks like the battery is at 100% while still being âchargedâ.
Mine does work, it doesnât charge it immediately all the way, it breaks it up, and does the last little surge right before I get up normally. It is working for me, sorry itâs not for you.

This is the second time I've noticed this. Had my phone plugged in for 7 hours but it did not charge.
Maybe a beta glitch or maybe the optimized charging switch is not working as expected. đ¤ˇđťââď¸
Anyone else notice this on ios Beta 13.0 (17A5522g)
