Problem facing with the Mac M3 air 2024

It's just been three months, I have got the new MacBook Air M3, and the battery backup for the M3 is not up to the mark which I expected at the initial days. It's not even giving the half of the battery life which claimed in the web or wherever possible...

Even when I keep the apps always updated and all the iOS is clean and fine without installed any other malware or foreign apps, but still the native M3 is facing battery issue, which is not only faced by me, but also other consumers of the Apple, "THE GREAT".

Answer I request Apple and also the manufacturing company to give a proper update or to just replace the new batteries for the product which are facing the issues like this if it's definitely falls within warranty. Peroid.
