Hello jaewoon,

Have you checked out Leaked: OS 7.1.0.342 For BlackBerry Bold 9900

It's a serious improvement over OS7.1.0.284.

Thank you.

I had done the upgrade, yet the situation still the same, drop 6 % without any usage, been try all the battery saving tips and turn battery save mood on..what's the problem?

It's sounding like you may have a bad battery jaewoon, if you have tried different OS, and tried the (OS7.1 feature) BlackBerry Device Analyzer > Battery Tests, it may be time to consider swapping to a new battery.

Thank you.

really? but my battery look just fine..just flat, din find any uneven surface
