Fishy battery life/ CPU Usage on Macbook Pro

Hey guys, lately my macbook pro has been experiencing some issues with battery life and high cpu usage even when nothing is running.

I looked at the activity monitor and two processes are hogging like 70 % and 20 % of the cpu respectively..

Anytime i quit the process it appears again a couple seconds later..

Any help?

Also right now safari is using 50 % of the cpu????

The computer in question is in my sig.

The only applications i have open are mail, activity monitor, and safari

Spotlight is indexing your drive(s), so searching for items will be faster. After it's done, your system resources will be freed up. Plug it in if your battery is running low. When Also Spotlight is indexing, it is evidenced by the mds process, which can peg CPU utilization.
You can also determine if it's indexing by the Menu Bar icon: (not indexing) (indexing)

u should go to system preference and disable indexing. It lowers cpu temp.

Or you could download onyx and disable indexing at startup.

There is no need to disable indexing. Just let it finish the process. It doesn't index at startup. It indexes a drive one time, then maintains that index as files are created/modified/deleted. If you disable indexing, you won't be able to find things when you search for them, or searches will take much longer to process.

It's because something IS open. The indexing is a process that is placing demands on your system and power consumption. When the process finishes, you should get much more life from a charge. To see all processes that are running, launch Activity Monitor and change "My Processes" at the top to "All Processes".

Also, you may benefit from reading the "BATTERY LIFE FROM A CHARGE" section of the following link. This should answer most, if not all, of your battery questions:
