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.

Did you crack and buy the 2025 version? Arrow lake or Panther Lake? RTX5050? Also Windows sleep has improved a lot from my 2023 model, now I can leave it one day in Sleep and will lose 1-2%, the older 2023 model had to be put in hibernation, otherwise I was losing more than 7-8. I told you the improvements of the 2025 versions are massive, even for Arrow Lake and not really appreciated. This is why I believe Panther Lake would not be such a huge upgrade.
