Maximizing battery life is something that many iPhone users deal with on a regular basis as we all want our iPhones to last as long as possible. Sometimes there are bugs in iOS that make the battery drain faster, and sometimes we just need to eke out as much as possible on a long day out and about.


In our latest YouTube video, MacRumors videographer Dan demonstrates some useful battery saving tips that can help you get the most out of your iPhone's battery, so make sure to give it a watch.

We also have a detailed, in-depth guide with tons of additional tips on maximizing your battery life, which is well worth taking a look at if your iPhone (or iPad) battery just isn't lasting long enough throughout the day.

Final step is to kill apps you aren't frequently using. It's commonly said, even by Apple execs, that those apps aren't truly running and that killing them doesn't change anything, but that's false in many cases. They can start up to handle push notifications, significant change of location, or other subtle things, except when they're killed. Developer docs go into this.

Of course if you want to be more data-driven, you can go look at the battery usage stats, but eh.
 
I’ve never done anything but leave my phone on a wireless charger for years while I work and when I sleep, and have never noticed any battery issues. My phone still holds a charge whenever I’m away (e.g only charge at night and that lasts a full day).

Maybe this is for people that need to go days without a charge? But I’m always able to charge at the very least every night while I sleep (and usually during the day while working).

I thought iOS already prompted users to turn on "low power mode" at 20% battery or so... I haven't seen that in forever, but my phone battery rarely gets that low anymore, so I don't know if the function has been removed. I guess the Siri shortcut is far more customizable, that's for sure.

As far as display energy, turning on "dark mode" is the sledgehammer approach, but you can also just set the screen background to black. It does require accepting the aesthetics of this choice, but on my black-bezel phone it looks great. As Dan mentions, on the OLED displays this strategy is very effective. I've held on to my XS Max longer than any other phone, and the battery is still great at 90% capacity.

iOS still automatically turns on LPM at 20%. I have it automatically turn on when I am charging. That way, my phone charges faster.

How do you know it stopped working? Seems like a strange comment. 🤨
I don't see this message anymore. That's how :(

Optimized Charging is not practical if you aren't on the same schedule all the time.

As to leaving the battery charging, create a Siri shortcut that turns off your phone charger once your phone gets to the battery charge level you want. That is what I do. I am surprised Dan didn't suggest that.
Not seeing shortcut action that "turns off your phone charger"
Maybe not available on all iPhones?

I use optimized battery charging and never get that message. Just because the message isn't appearing doesn't mean its not working in the background. Thanks for the big iphone pic.
Correct. The message only appears when the software has decided to not charge even though the battery is below 100% and the device is plugged in. I imagine Apple did this so people wouldn't think something was malfunctioning. MacOS has a very similar notification.

My battery saving techniques also make my phone less annoying. I personally couldn't imagine getting notifications for everything. Currently just messages, Favorite people's emails and Twitter DMs.
Mail only refreshes when opened
Background app refresh off
Auto updates off
Raise to wake off
No widgets
Auto scan Wifi off since iOS 5(where you get prompted to join local networks)
