Is leaving the battery plugged in all the time bad?

[djm1952]

I have read that it's bad to keep charging a battery once it reaches 100%.  My iPhone charges slowly at night so that it reaches 100% at the time I wake up.  My previous Asus laptop had an option to stop charging at 80%.  

I have a new HP Spectre X360.  I use the HP USB-C charger and an HP travel hub.  Most of the time it sits on my desk with an external monitor.  Will leaving it plugged in most of the time harm the battery or reduce the battery life long-term?  I would hope the HP USB-C charger would be smart enough to avoid doing anything harmful.  I've seen guidelines on this forum from 5 or 6 years ago - have batteries and chargers gotten better or smarter since then?

Hi:

Since it is new, your notebook may have an adaptive battery optimizer setting in the BIOS you can enable.

I don't think it is a good idea to leave the notebook plugged in 100% of the time 24-7 despite the fact that the charger shuts off at 100%.

For some reason leaving the battery in a 100% charged state all of the time may lead to battery swelling.

I recommend that you review the info at the link below for how to get the most life out of your notebook's battery.

Thanks for the helpful reply.  Last week I started using an AC outlet timer and turning on the charger for four one-hour periods a day.  It seems to be working well - the battery gets down to 50% sometimes and sometimes doesn't get above 93% but it certainly isn't connected to the charger 24/7 anymore.  Is there any problem with doing this?

You're very welcome.

I don't see any problem with what you are doing.
