Monitor your battery usage starting off from a clean slate. You can clear battery stats if you have recovery installed or use the free app BatteryCalibration
And it is safe and will not spoilt your phone to have it always on charge
Just as a guide :
Overnight 7 hours period : with 3G disabled - battery drop 3-5%
Overnight 7 hours period: with 3G on and active data refresh updates ( 3 email accounts every 15 mins, few apps RSS, newsfeed, tweeter every 30-60 mins ) : 20-25 %
Day use 7 am till 7 pm : full charge till 10 % left
Usage : 3G always on and sometimes thro WiFi when available - active data refresh updates ( 3 email accounts every 15 mins, few apps RSS, newsfeed, tweeter every 30-60 mins, weather updates every 4 hours . Browsing - about 2 hours, phone calls/SMs about 10, no gaming
If you use your phone a lot for gaming or use it as wifi hotspot, the battery will drains a lot. Example using it as wifi hotspot , be prepared a drain of 20 % in an hour
