macOS recently introduced the ability to limit your battery to only charge up to 80%, a feature that I personally appreciate as I’m mostly using my MacBook plugged into a dock and it’s arguably a great way to limit the ageing of the unit.

There’s just one huge problem. Well, two actually. Firstly it doesn’t allow me to set a minimum charge (“start charging when battery is at X%”), so when it falls to 79% it just tops it back up to 80, not a big deal but slightly annoying. The much bigger issue is that the charge limit apparently isn’t being saved to the battery firmware itself so when the MacBook is turned off and plugged into my dock it just keeps on charging to 100%…

Similar issue with my Pixel 9 Pro, it normally sticks to the charge limit quite well, but multiple times a month I’d say it just randomly charges to 100% regardless. Apparently that’s to calibrate the battery or something? As far as I know you have to do a complete cycle to calibrate a battery which 80% to 100% isn’t, also I don’t think a Li-ion battery needs to be calibrated this often, does it?

To contrast, KDE Plasma retains the limit at all times, lets you set a minimum amount and actually tells the battery to always stop charging at that amount.

Am I just not getting something about this?

    I can’t really complain… then again I probably disabled most of the features you’re talking about

      Where are the options for:

      • Make screen not randomly hang, filled with ghost images and artifacts
      • Have phone actually give notifications when they arrive
      • Respect battery charge settings
      • Have app-switcher not randomly stop accepting swipe inputs

        I think they may have fixed the app switcher thing? Or at least one of them.

        Here’s the scenario I kept running into on my 6. I’ll give the apps names to simplify the description, but the problem was generic. So let’s say I’m in Firefox, and I want to glance back at something in signal. So I double-tap “recent” to switch to my previous app, but what comes up is instead WeatherBug, because I forgot I glanced at that between Signal and Firefox. So I still want to go to Signal, but when I get there, I want my previous app to be Firefox, not WeatherBug, so I double-tap recent again to get back to Firefox as an interim step. Then I hit recent yet again, and this time the whole screen freezes up and won’t respond to touch. The workaround I found was that if you interacted with the screen on WeatherBug–usually I’d just scroll it down and back up a tiny bit–it wouldn’t lock up. So I got in the habit of doing that.

        Recently there’s been a change, though, and it seems to fix that bug. Unfortunately, it also screws up the “switch to last app” functionality sometimes. Now I’ll be in Firefox, open recent apps, scroll past Weatherbug to open Signal, and when I double-tap recent, it’ll switch to WeatherBug.

        So it’s still a screwy mess, but at least it’s not locking up as often anymore.

        Ok, that sound more like your phone is kinda iffy. I don’t mean to piss you off by saying this, but have you tried a factory reset?
