I'm on AC like 90% of the time, and afer a year much to my surprise my laptop battery has hugely degraded performance.
I would've thought when you're on AC, the power can completely circumvent the battery and put no wear on it. I remember in the age of replaceable laptop batteries, I could replace the battery while connected to AC (or run without a battery) no problems
- Gracana 10y agoPretty much everything degrades lithium ion battery performance. Charging, discharging, being fully charged, being too hot, being thought about too much or too little, etc. If it's plugged in, it's probably hot (running in full-power mode) and fully charged... this kills the battery.
- Scarbutt 10y agoIf you don't use the battery it will die quicker, you need to move those electrons, try using AC only 40-50% of the time.
- khedoros1 10y agoBatteries have a certain amount of slow discharge, even when they aren't running anything. People like seeing a full battery all the time, but I don't think it's very good for the battery's life to keep it constantly topped off.
