My macbook lasts about 2.5 hours when i just have itunes and safari open. Is my battery bad?
 
Odds are you probably have a lot more than Safari and iTunes open. Is iTunes playing music? Are you watching YouTube videos or something? These can all contribute.
 
A big thing is screen brightness. The difference between having your laptop at full brightness and close to dark can make a huge difference. Try keeping the brightness as low as comfortably possible so you can maximize battery life.
 
My battery capacity is still 100% and with itunes, there was no music and i was on macrumors on safari and that's it. also brightness was about 75%
 
Try downloading Coconut battery or battery health monitor. This will provide info on your battery capacity and health

Thankyou very much for your input😎

Open Activity Monitor, see if anything is using up a lot of CPU in the background.
Make sure you don't have any login items that are set to hide themselves.
Try recalibrating your battery.
 
Okay. For CPU:

Safari - No More than 50.0

Activity Monitor - No More Than 5.0

Everything else is usually less than 5.0

I've already re-calibrated my battery.

If Safari is running Flash apps/video, that's why.

50% CPU being used is fairly significant in terms of battery life/usage.
