ry changing the battery power settings to "better battery" and not power saver (I always found that drained more for some reason). Then in the Dell app choose the battery mode or "quiet mode." Finally in the Nvidia GeForce (might have to download this) and Display settings (right click on desktop and choose Nvidia) app choose battery life deep in the settings somewhere. Then try again. If you do anything more intensive than watching a YouTube video on battery it will drain much faster. 2.5 hours is what I've seen the battery can last while playing GAMES.
I had already bought this laptop like 3 months and I had made a mistake that I didn't test its battery life when I got it and now when I need to use it for school, my laptop just give me 2 hour of battery life just for doing PPT and Microsoft Word. I also do a clean install windows 10 on my latop but my alienware command center have issue, it cant enable the G mode, so I go to windows 11 to see can fix or not and it works ( but only can enable G mode, it still show 'No Supported AlienFX devices was detected' which I don't know why). So, now the problem I have is it just provide 2 hour of battery life sometimes 1 hour and a half only. Is there any solution for me, I have already seen all the dell support video on fixing battery life but it doesn't work at all.
Dell G15 5511 only have 2 hour battery life
