Acer Aspire A715-51 - short battery life and auto refresh rate adjustment

SeaLukino336

Hi all, I've recently bought a very nice Acer Aspire 7 A715-51G-50FF. It's got the power hungry i5-1240P and a really cool RTX 3050.

I have two questions: even if the battery, with every single new processor out there, on battery power, lasts forever (at least if it's not a gaming-oriented laptop, as I had an Asus Vivobook 16X with the Ryzen 5 5600H that could last like 6 hours on a single charge and it has similar performances to this i5), in mine cannot go past 2 hours. How is it possible? I would like to know if there is a way to force the CPU to a power saver state when on battery, and then if it's possible to have a script/program that sets automatically the refresh rate to 60Hz on battery and 144Hz on AC power

Hi, comparing power usage of AMD Radeon RX Vega 7 with the 75W RTX 3050 GPU is not realistic, you should leave the power adapter plugged in 24/7 as your battery will be depleted in <1 hour by the RTX 3050. Use Best Power Efficiency in Windows11 23H2 (Power & Battery settings) and you will get better backup or reduce the Maximum Power Processor state when on battery to 95% in Advanced Power settings. Check if your laptop supports Dynamic Refresh Rate (DRR) in Windows to save battery power.
