battery life drop fast only under idle state?

[mystory]

Hello,

Why my stock battery life drop fast only under idle state? It was a 1 yr old Note 4 from my cousin and the issue doesn't happen with the mpj 6440mah extended battery which I bought recently. Anyone out there ever had this problem?

Thanks!

This problem usually occurs due to the apps that runs in the background. And the 3D wallpaper/screensaver too! Try stopping them and see if it works.

Either bad stock battery or a drain may just not be as noticeable on the larger battery.
