Video: Make Your iPhone Last Longer With These Battery Preserving Tips

[JosephAW]

Wait a second - "Battery Preserving Tips" - in 2021? The first iPhone is from 2007 - all problems should have been fixed and battery problems shouldn't exist.

Agreed. We should be on fuel cells by now with three weeks between changes.

Yeah. No idea what this guying is thinking.

When you swipe up to close an app, that is QUITTING it, not force quitting it. iOS shuts it down. You aren’t control alt deleting it…

I think it sends a sigterm, which is the same as Mac force-quit (idk about Windows cntrl-alt-del). People say there's no way to know when your app is being force-closed, no AppDelegate handler or anything, and presumably they don't give you a way to handle OS signals. Anyway that's still a normal thing that an app has to be prepared for. Everyone closes apps; if they don't swipe them away, they close the apps when rebooting the phone.

Apple's file API has an `atomic` write option for a reason, and I'll bet at a lower level it's listening for the sigterm. The harder way to quit is sigkill (-9), and that is likely to leave files in a weird state, but closing apps doesn't send that.

Realistically I've never encountered an app screwing itself up due to closing it, which I do all the time.

why would I not want to charge my iphone over 80%?

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.

Duplicate post, sorry

You can create it using the Home app > Automation

Do you mean you have a home kit accessory (smart plug) that controls your charger?

Yes. I set up a Shortcut that turns off the charger after the phone reaches whatever charge percentage I want.

Very clever! Did you by any chance manage to setup a similar action in macOS? With lid closed? I fumbled with AlDente and some github scripts but when the lid is closed the charger continues to 100%.

AlDente doesn’t work in clamshell mode.
