    My 13" 2017 Air suddenly died today from power loss while running on battery with ~80% charge, and now it will not power up at all from battery. If I remove the battery it powers up fine from the power adapter. If I measure the battery's voltage when disconnected (unloaded) I get nominal 7.8...

    Ultra - How to enable Optimized Battery Charging?

    When I first got my Ultra last year it would always charge overnight to 80% and then last all day; even when I was doing three or four scuba dives per day using the Oceanic+ app. Then I upgraded to WatchOS 9.4. That started four or five days of rapid battery drain. I guess to compensate the...

    Battery Life Is Horrible - Macbook Pro

    Google Drive Background Activity

    So I guess this doesn’t need much explaining… just, WOW! Doesn’t seem to affect battery life much, if at all. Background App refresh is disabled… iPhone 14 Plus 256Gb on the latest iOS. Needless to say I’m at a loss for words 😂
