We have noticed the battery on the Latitude 5530s only last about an hour (or less).  It seems to be the same with Windows 10 or Windows 11.  The batteries are 58,003 mWh.  Turning off Intel Turbo Boost in the BIOS helps the battery life, but we have a tradeoff in a higher CPU usage with other processes such as Windows Defender which can be noticeable when the AV scans start.

Trying to find out if others are seeing this and what you might have done to extend the battery life.
