guys .. wanna ask for help .. i'm new to mac world ..
on july, i bought mid '12 13inch base-line mbp with lion on it .. after few weeks, i update to ML .. and i saw changes in my battery life .. it wont get more than 5 hours for full charged battery and now, its already down to 89% from its design capacity (based on coconut battery) .. the battery cycle is only 24, and i only use my mbp for surfing, word processing and other student life usage (light usage only) . it is mostly used while plugged in and once a month, i did the battery drain thing .. and after ML, the battery drain like its really2 thirsty .. lost 1% for like every 2 minutes ..

anyone could help me with this? cuz im new with mac .. thanks guys
