Did you have an automated way to do that?
- usefulcat 3y agoI wish I did but I haven't found one yet. I'm at my desk a lot, and that's usually when I charge it. I mostly use an old, low-current charger (originally for a bluetooth headset) so it charges slowly, about 5% per hour.
- euroderf 3y agoWhich begs the question: if I charge my new Mac with an iPhone charger (8W), will it lengthen the battery life ?
- ponector 3y agoI don't think so. You need 20V to charge a laptop
- hrrsn 3y agoProbably not, seeing as that's not enough power to charge it up.
- euroderf 3y agoAnswering peer comments: oh but it DOES work. I forgot my charger in another town so I bought a USB-A/C cable and tried it out. Again, the iPhone charger is 8W. This is also the value reported by '/usr/sbin/system_profiler SPPowerDataType | grep Wattage' When the Mac is open and in use (2023, M2) the iPhone charger can just about keep the charge level level, depending on usage. But then when I close the Mac, it can easily take 10 hours to reach a full charge... but it does hit 100%. So I am wondering if this is in fact a gentler way to charge the battery.
- Izkata 3y agoMy crude understanding is the charging speed wouldn't directly have an effect, but the heat generated by faster charging would.
- euroderf 3y agoAlso if it takes hour and hours to charge with 8W, then it becomes easier to unplug it at or around 80%. So maybe it's the best way to charge the Mac - a way that all the cool kids will be doing :)
