[MENTION=30436]RameeX[/MENTION]! From 10am to 7PM, consider yourself extremely lucky. This is not a battery drain issue. Its the battery itself, and ontop of that the power sucking Sense ROM. Flashing a non-sense ROM would make things slightly better by adding 1 or 2 more hours on the battery timings.
Otherwise, during my usage, 4-5 hours was the maximum i used to get, and that was just a couple of calls, 20-30 minutes of small time games and handful of SMS ... and its down to 10%. I was able to drain a OneX's battery in roughly 2.5 hours under gaming and honestly, it was pretty preposterous.
So just deal with it.
