    Also, I do see on Amazon Ap18e7m, but none of them say it is for my model number(ph315-54). I also tried to use the Acer Care Center battery calibration, and also by doing a 100% charge unplugged and then going to 3% and charging again as well

    Hi, the battery report shows only 27% wear which is good for a 1.5-year-old battery (was replaced in 2023), no need to buy a new battery. Change the Power Mode to "Best power efficiency" in Power & Battery settings.

    and open Task Manager-Processes. If you have more than 70 background programs running, you should uninstall some programs you don't use and disable the Startup programs you don't need. Also don't use Acer Care Center Battery Calibration option but do a Full Charge Cycle routine, only required once when you install a new battery or reinstall Windows. Disable Fast Startup and Hibernate in "Change what closing the lid does" and in "Change settings currently unavailable". Reboot and plug in the power adapter and charge till the amber battery LED turns blue and the battery meter on the task bar reads 100%, wait 10 minutes and unplug the power adapter, work the laptop till it shuts down on its own, don't suspend, don't touch the power button and don't turn off the laptop, just close the lid. Plug in the power adapter and charge with the lid closed till the amber battery LED turns blue and wait 10 minutes. That's it. After a few days run a new battery report and see if the battery backup has improved, should be around 2.5 hours.
