ICS Battery Usage

I searched if there is any way to increase battery performance of my Sony Xperia, as after updating to Ice Cream Sandwich, the battery consumption rate is increased.
Even the Google site recommends only these suggestions, that may be already done by most of the common users.
1: Offing GPS Settings > Personal > Location services.
2: Brightness Settings > Device > Display.
3: Syncing Data Settings > Personal > Accounts & sync. 
4: Sim Range Airplane mode:

To know how your Battery is used by different apps, go to
Settings > Device > Battery.

    I got this data by going data settings.
