My macbook lasts about 2.5 hours when i just have itunes and safari open. Is my battery bad?
What year is it.
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.
Energy Saver settings, but, Coconut should tell a lot of information.
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
Something aint right.
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.
What is the health?
If Safari is running Flash apps/video, that's why.
50% CPU being used is fairly significant in terms of battery life/usage.
No, that's max. Most of the time it's around 15%.
thats a lot 15% for safari is usually using about 1-3 precent when im just reading articles
Safari, FF, and iTunes are currently idling on my machine right now, taking up a combined 8% of the CPU. You must be doing something within those programs that is sucking battery life.
