Question HTC One S Battery Life After Custom Rom

I have a question for those of you who have installed a custom rom like TrickDroid on your t-mobile htc one s - how is the battery life after using the rom? I am on the verge of picking up the one s myself (coming from a G2) and the only thing that's holding me back still is the stat shown for web surfing based on gsmarena's latest test below. The 4 hours browsing time really puts the one s at the bottom of the pack of new and old smart phones. Other than this, all other run time appears to be excellent.

I know that amoled screens are bad for web browsing as the mostly white-colored pages is what eats up battery. With the custom rom, those of you who are heavy users and browse a lot on your phone, does it last through an entire day without issue? TIA!
