The check status of the battery that you can do is already done by coconut battery. Those results suggest that you can still use the battery till it heat 1000cycles, or 80% of capacity.
Now regarding your usage stats, it depends on a lot and a lot of factors as wifi usage, Twitter, phone calls do not define the condition of the battery, even if it's brand new battery, those activities only would not define how good or bad the battery is.
Brightness could be at 70%? Locations services could be turned on? Fetch mail is on? Spotlight is on? Background app refresh is on? Is your gsm signals full 24/24h? Is Bluetooth on? While browsing, are you doing videos that out put audio? Is videos or browsing real faster? And the list goes on...
The best way to check about how your battery is holding on is to put it in 2g only (3G/wifi are off) after a full charge, and let it be in stand by mode until it completely drain out, compare that amount of time is used to deplete with the time advertise by apple in regards to that series of iPhone you have. If it get closer to 250 then your battery is good, as apple advertise 250h of stand by mode in 2G or 3G, but apple doesn't mention if you will have 250h of stand by while location service is on, fetch mail is on etc...
