Why does my batter only last 3 hours?
My battery dies after 3 hours of use, and the laptop is only a year old.

Hi @dominicka
Create a battery report to check on the condition of the battery.
When you have the report, scroll to the bottom of the report to find the expected life of the battery.
For a good battery they should nearly be the same value.
If the battery life is <40% since it was new, first check to see if it is still covered by a warranty and if it is get it replaced under warranty.
If no longer under warranty, the battery may be just starting to fail.
Here's the hardware maintenance manual for the laptop. Go to p.28 (34 of 56 pdf) in the manual, to see how to remove/replace the battery.
There are two batteries that can be used that are compatible with the laptop. Search online for either 5B11N42051 or 5B11N42049 to find suppliers that suit you best. (examples only)

I have had a couple of staff who use this model report battery life issues, but there was a cause not related to the battery itself. They were spending the entire day in Teams meetings while unplugged. The Teams video decoding in their video calls was a resource intensive task that consumed quite a bit of power. I'd also suggest sticking to dark mode since this device uses an OLED display. I purchased our first batch about 14 months ago. If yours is about that old you may be showing battery degradation as well.
