    The 54.6Wh battery pack can last 9 hours and 5 minutes of Web browsing or 7 hours and 9 minutes of video playback with brightness reduced to 120 nits. Possibly you are not fully charging the battery, are you using battery Limiting software or the 80% Battery Charge option in Acer Care Center perhaps? You also have a USB-C port that supports Thunderbolt4 power delivery. Get a 90-Watt USB-C charger and see if you can charge the battery to 100%: https://www.zdnet.com/article/best-usb-c-laptop-charger/ It is also possible that Windows Battery Meter is not reading the battery capacity properly if you never completed a full charge cycle. Boot to BIOS with F2 and reset with W9, save settings on exit and reboot to Windows, uninstall the 2 battery drivers in Device manager and reboot:

    Charge the laptop till the amber charge LED turns blue and let it charge an extra 5-10 minutes. Unplug the adapter or charger and work till the laptop turns itself off (4% charge left), plug-in the adapter or charger and again charge till the amber LED turns blue, Boot to windows and create a Battery Report with the Command Prompt:
    powercfg /batteryreport /output "C:\battery_report.html" Check if the battery has been charged to 100% ad what the remaining hours life is.

    I recommend to uninstall all Power monitors, limiters and other charging bloatware you may have. Don't use the ACC 80% charge option as this interferes with BIOS and MS ACPI battery control protocol. You can leave your adapter-charger plugged in 24/7 without causing any extra battery wear. Replace your battery after 4 years. The full charge cycle procedure is only once required when a new battery is installed so BIOS and Windows can register the capacity of your battery.

    tried everything still last only 3hours and even the battery is non removable like come one if it last only 3 years we should be able to change it witout going to nearest service center and we had to pay for their services this should be norm im kinda disspointed also that theres no official acer software that able to downclock even your bios ueifi is just had minimal settings to tweak the power like enabling any idle or cie state

    Depending on your processor, 4-5 hours is probably a more realistic lifespan for a new battery with Balanced Power Plan for the average user (Battery Saver on, moderate brightness and just browsing the internet). The 3 hours you are getting (are you including the 4% reserve not used?) till the laptop shuts down can be improved by 1 hour, I am sure, by tweaking advanced Power Plan settings and aps functions (prioritize memory use of highest resource in Task Manager Processes). 😉

    By enabling some hidden power plan and modifying its settings i got to get 7 hours which is not available on acer if we can modify idle and power states on bios we can max battery on this laptop or has mux switch this laptop is great but it lacks user control like disabling turbo boost thanks on reddit for those configuration also i disable fast startup and disable some windows 11 settings btw im not runnign battery saver here and i just modify the acer power plan
