My Gram battery saving - what does it do?

[extremecarver]

Usually I don't believe much in whatever apps supplied by vendors making claims about battery life improvement - but what does My Gram do?

 

On idle it decreases the CPU package from 0.5-0.8 to 0.3-0.7 watts - that's really crazy low. I left my 2025 16 Gram Pro in idle with browser open and display off prevented for 2 hours and it only dropped  6.1 % battery - screen brightness at 30% which should be around 150 nits. That would be well over 30 hours of battery life.

 

Surfing the web and browsing I usually got without gram about 6-7% per hour, but with my gram only 5% per hour - meaning around 20 hours batttery duration in real life. Yeah not panther lake levels but not far off. Wifi/Bluetooth both on. System drive Lexar NM790 - the lowest power use NVME with Devsleep (lowest) enabled.

 

I really do wonder what windows settings does My gram change.
