My laptop is Acer Nitro V15. I5-13th gen with RTX 4050. Issue with my laptop is that when it is unplugged it runs very slow and lags very often. When it is plugged in it runs smoothly with no issues. I've already put best performance when on battery, process power management set to 90% and 100% for minimum and maximum respectively. My Nitrosense to balanced when on battery and not Eco mode and yet it still performs the same, slow and lags when unplugged.

I've did some testing and realize that when plugged my CPU core clock averages around 1.7k to 2.5k Mhz when plugged in but immediately drops to 400-700Mhz when unplugged and remains in that range. Anyone know how I can solve this issue?

    Hi, if your full Nitro model is ANV15-51 update BIOS with the new 1.26 version dated 2025/04/17 and upgrade Windows11 with version 24H2. Don't use Best Performance Power Plan in Windows but Best power efficiency mode in Power & battery settings (see red box, picture)

    Don't use a USB-C charger but use the original power adapter that came with the laptop, leave the adapter plugged in 24/7 and make sure that the battery stays fully charged at 100% at all times.

    Make sure that you have the last bios version 1.26 installed and all the Win-11 24H2 and its updates so that you are running the last OS build: 26100.4202, as that is crucial.

    Your laptop could also have a charging rail issue that is affecting the battery, as the that is ANV15-xx model laptops have an issue with their adapter’s crash half way in extreme gaming even if the adapter is plugged in. If your laptop is still under the Acer 12 months initial warranty, I suggest that you send your ANV15-51 to Acer Tech Support in your country as there could be some mainboard issues and Acer will replace the board, if not, then you need to take your laptop to a technician and get them to analyse the charging rail as there is a problem there that needs fixing, hence and why your battery is defective and it doesn’t charge properly, as new laptop like the ANV15-51 should not lag or work slowly on battery power. Good luck and hope this helps you out.

    Thanks. But I just checked my BIOS version it's already the new version 1.26 as well as Windows 11 version 24H2. And my adapter has always been the charger that came with my laptop.

    The battery health and charging port seems to be doing fine as I never experienced anytime where my charger would halt or fail mid-way, or my battery would drain faster than usual.

    Leave the adapter plugged in 24/7 and make sure that the battery stays fully charged at 100% at all times.. Use Best power efficiency mode in Power & battery settings.
