I've had my Macbook Pro 13" for little over a year now, when I bought the thing it was claimed I could get 10 hours battery which is perfect for what I need (uni). At this moment in time its running the latest Lion 10.7.1, its stock so 4GB ram, 2.4ghz blah blah blah. This morning (like everyday) I take it off charge, instantly it was at 99% battery. I've used it now for *checks iStat Pro* 1 hour and 58 minutes and I'm down to 18% battery :(. All I do is surf the web, a little iTunes and thats about it. Whenever Im on a site that requires flash the fan kicks into turbo mode (sounds like a jet engine) and the battery percentage turns into like a ticking timer "76%, 75%, 74%" so I have to come off these sites so save battery. The heat is unbelievable on it that Im considering using it to cook my breakfast on. I've used those "Click for flash" programs but they dont work so well, I calibrate the battery a couple times a week, according to iStats the health of my battery is at 88%. I have to charge it about 2 or 3 times a day, Im trying to be as energy efficient as possible with the battery but it's becoming a joke now!

Also quickly I took my mac back a few months ago about a dodgy speaker and the poor battery, they replaced the speaker and battery and things were fine for a wee while but things are just back to square one, I can't listen to anything because the left speaker cracks, and when I do anything its only for 5 minutes until the battery dies :(

To sum up
-RUBBISH battery
-Hot hot hot mac
-Fan on constantly
-Speaker keeps crackling

Anyone with any advice would be my new best friend!!
 
Flash might be the culprit.
______________________________________________________
Have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.
Also check the "System Memory" tab to see what your "Page ins:", "Page outs:" and "Swap used:" are.

Also constant calibration might not be the best for the battery, though if you can't do it any other way, then so it is.

If you used the Search feature of this site like you are supposed to before creating new threads, you would find dozens of existing ones on this exact same subject which you could have used to educate yourself.

Flash is a known battery drain. Your computer is behaving perfectly normally.
 
My macbook has been heating up very much since I updated from 10.7.1 to 10.7.2. It's not flash because I don't have it installed. Before I could idle off the charger at under 50 degrees C but now just idling I'm at 65 degrees C.

Has anyone else experienced this problem? I searched the forums but this is the only thread that came up about heat in the first three pages.
 
Hi taylor200588,

Have a look at the spotlight icon (in the upper right corner of your screen). Is there a small, pulsating circle in the middle of the magnifying glass?
