Apple launched a brand new software program function with iOS 13 that helps lengthen the lifetime of your iPhone’s battery known as “Optimized Battery Charging.” I’d like to see Apple not solely develop it to iPad and Mac but additionally take a web page out of Tesla’s e book (and Dell, Samsung, others) and undertake a function from its charging technique.
Replace 1/22/21: After two months, my 13-inch M1 MacBook Professional has discovered my charging schedule and is limiting charging to 80% with Optimized Battery Charging.
It’s good to see the function lastly kick in, however I feel it’s additional proof that guide management for setting a battery restrict is required.
In my case, since I work at home linked to a Thunderbolt Show throughout the day (and unplug it on the finish of every workday) Optimized Battery Charging “discovered” that my Mac can keep at 80% throughout the day and end charging to 100% by 7 pm (if I left it plugged in).
I additionally attempt to run down the battery a bit after work by taking part in film so it’s not sitting with a full battery in a single day constantly.
Replace 12/24/20: It’s now over a yr since Apple launched its Optimized Battery Charging function and it hasn’t actually been improved. And searching again on 2020 – a yr with the pandemic and the launch of the primary M1 MacBooks, full battery management for charging is unquestionably overdue.
With macOS Massive Sur that launched this fall, Optimized Battery Charging is turned on by default. That’s nice, however apparently, I’ve observed it doesn’t ever kick in on my 13-inch M1 MacBook Professional. Granted, I work at home and use an exterior Thunderbolt show that concurrently fees it, however I nonetheless can’t get it to pause charging at 80%. I’ve tried quite a lot of issues, together with working my MacBook under 80% and plugging in round 10 am for per week constantly, nonetheless nothing, it at all times fees straight to 100%.
I might guess extra folks than ever are in the identical boat as me as working remotely/from dwelling has change into a norm throughout the pandemic.
And that’s simply a part of it. The M1 MacBooks have massively improved battery life and that is bizarre to say, however the longer battery life is definitely a part of the issue right here, haha! It’s genuinely tough to run my MacBook battery down under 80% if I don’t do half of my workday with out my Thunderbolt show.
Like 9to5Mac readers beforehand identified within the feedback (thanks, all!), Dell has been providing guide battery cost management since round 2012. Samsung and different Android OEMs are additionally providing related choices.
This yr has actually confirmed that it’s previous time for Apple to present customers the flexibleness to prioritize long-term battery well being. A easy opt-in guide management for limiting the battery cost would do the trick. And notably, with folks being dwelling far more than ever (at the very least for the primary a part of 2021), guide management on iPhone and iPad can be very helpful now and even when life will get again to regular.
Within the meantime, there’s a pleasant third-party possibility available on GitHub called AlDente developed by David Wernhart. Nonetheless, it’s not appropriate with M1 Macs. “AlDente is presently NOT engaged on Apple Silicon (M1) MacBooks as a result of some SMC Key Adjustments!”
For those who’re simply catching up on all this, try all the main points within the unique publish under:
Apple’s Optimized Battery Charging function for iPhone in iOS 13 works by placing a brief battery restrict of 80% on the system when charging in a single day. Then extra carefully to if you get up, it’ll end charging the remaining 20%. Apple describes the way it works in Settings > Battery > Battery Well being:
To scale back battery getting older, iPhone learns out of your every day charging routine so it may wait to complete charging previous 80% till you’ll want to use it.
The gist is that batteries sitting charged at full capability will put on out the cells quicker, so Apple’s function will increase battery lifespan by pausing the cost.
Tesla’s electrical autos have an identical functionality the place they be taught your schedule like iPhone and will probably be charged to the specified degree by the point you’ll want to depart within the morning. However Tesla goes additional than Apple’s Optimized Battery Charging function and permits homeowners to manually set a battery restrict within the Tesla app.

Tesla CEO Elon Musk has shared that charging to 80% for regular use after which tapping in into the remaining battery for lengthy journeys is finest. And a battery professional who has completed analysis for Tesla has even advised utilizing a 70% limit may be ideal for battery longevity.
Despite the fact that a few of Apple’s batteries in its gadgets will be user-replaceable, they’re not designed that approach, and it may be a dangerous possibility in some circumstances. Giving customers the flexibility to set a battery restrict and prolong battery life even additional can be a good way to increase a battery/system’s usable life, cut back waste, and make it extra seemingly for patrons handy down or trade-in once they’re able to improve. Despite the fact that it may cut back a few of Apple’s income within the huge image, I feel such a transfer is in keeping with Apple’s values of sustainability.
Whereas I feel this is able to be an incredible function for iPhone, iPad and Mac could profit much more. Many Mac pocket book homeowners depart them plugged in on a regular basis (or at the very least quite a lot of the time). Introducing a Tesla-like battery restrict function would supply the advantages we’ve talked about in addition to educating all of the customers who don’t notice leaving a battery sit at 100% cost shortens its life.
And other people have a tendency to carry on to iPads and Macs longer than iPhones, so this might provide a greater general expertise by eliminating the necessity for a battery substitute or at the very least pushing it out additional within the system’s lifecycle.
Identical to the present Optimized Battery Charging function, Apple may implement the flexibility to set a restrict in battery settings and provides customers a notification concerning the possibility, making it opt-in.
