    Hi @Anshul42 what model do you have exactly?
    Do you mean that the battery is lasting less time?
    Are you using and maintaining the battery correctly?

    Regards.

    All batteries lose capacity with time either used or just stored, battery wear varies with quality, an Acer endorsed battery can last between 4-5 years, a cheap or refurbished one may not even last 1 year. If you notice battery wear (Design Capacity minus 100% charged capacity) is around 15%/year that is very good, if you get 2-3 hours battery life without the adapter plugged in that is normal. Don't use Acer Care Center Battery Calibration or Battery charge limiting options. I recommend leaving the power adapter plugged in 24/7 and make sure the battery is always 100% charged. If you don't have access to an electrical wall outlet, disconnect USB/other external devices, change the Power mode in Power & Battery settings to Best Power Efficiency", turn off keyboard backlite, turn on the screen saver and reduce your screen brightness, this may give you >4 hours battery life with a new battery,
