But Tesla goes further than Apple’s Optimized Battery Charging feature and allows owners to manually set a battery limit in the Tesla app. Tesla’s electric vehicles have a similar capability where they learn your schedule like iPhone and will be charged to the desired level by the time you need to leave in the morning. The gist is that batteries sitting charged at full capacity will wear out the cells faster, so Apple’s feature increases battery lifespan by pausing the charge. To reduce battery aging, iPhone learns from your daily charging routine so it can wait to finish charging past 80% until you need to use it. Apple describes how it works in Settings > Battery > Battery Health: Then more closely to when you wake up, it will finish charging the remaining 20%. If you’re just catching up on all this, check out all the details in the original post below:Īpple’s Optimized Battery Charging feature for iPhone in iOS 13 works by putting a temporary battery limit of 80% on the device when charging overnight. “AlDente is currently NOT working on Apple Silicon (M1) MacBooks due to some SMC Key Changes!” However, it’s not compatible with M1 Macs. In the meantime, there’s a nice third-party option available on GitHub called AlDente developed by David Wernhart. And notably, with people being home much more than ever (at least for the first part of 2021), manual control on iPhone and iPad would be very useful now and even when life gets back to normal. A simple opt-in manual control for limiting the battery charge would do the trick. This year has really proven that it’s past time for Apple to give users the flexibility to prioritize long-term battery health. Samsung and other Android OEMs are also offering similar options. Like 9to5Mac readers previously pointed out in the comments (thanks, all!), Dell has been offering manual battery charge control since around 2012. The M1 MacBooks have massively improved battery life and this is weird to say, but the longer battery life is actually part of the problem here, haha! It’s genuinely difficult to run my MacBook battery down below 80% if I don’t do half of my workday without my Thunderbolt display. I would guess more people than ever are in the same boat as me as working remotely/from home has become a norm during the pandemic.Īnd that’s just part of it. I’ve tried a variety of things, including running my MacBook below 80% and plugging in around 10 am for a week consistently, still nothing, it always charges straight to 100%. Granted, I work from home and use an external Thunderbolt display that simultaneously charges it, but I still can’t get it to pause charging at 80%. That’s great, but interestingly, I’ve noticed it doesn’t ever kick in on my 13-inch M1 MacBook Pro. With macOS Big Sur that launched this fall, Optimized Battery Charging is turned on by default. And looking back on 2020 – a year with the pandemic and the launch of the first M1 MacBooks, full battery control for charging is definitely past due. Update 12/24/20: It’s now over a year since Apple released its Optimized Battery Charging feature and it hasn’t really been improved. I also try to run down the battery a bit after work by playing movie so it’s not sitting with a full battery overnight consistently. In my case, since I work from home connected to a Thunderbolt Display during the day (and unplug it at the end of each workday) Optimized Battery Charging “learned” that my Mac can stay at 80% during the day and finish charging to 100% by 7 pm (if I left it plugged in). It’s nice to see the feature finally kick in, but I think it’s further proof that manual control for setting a battery limit is needed. Update 1/22/21: After two months, my 13-inch M1 MacBook Pro has learned my charging schedule and is limiting charging to 80% with Optimized Battery Charging. Apple introduced a new software feature with iOS 13 that helps prolong the life of your iPhone’s battery called “Optimized Battery Charging.” I’d love to see Apple not only expand it to iPad and Mac but also take a page out of Tesla’s book (and Dell, Samsung, others) and adopt a feature from its charging strategy.
