Help Samsung Galaxy S3 getting slower

I could really use some advice here. I currently have a Galaxy S3 on T Mobile. I use the phone A LOT. I probably kill 2-3 batteries per day. The phone was bought new in November and is not rooted. It is on the current update and running stock.

The phone has gotten perpetually slower and slower, especially when texting. Text messages take 10+ seconds to open and often when I type it hangs up for 5-10 seconds before letters appear. It has now gotten so bad it take 10+ seconds to go back to the main text screen and I am not receiving about 1 of every 20 texts. Regular programs all run slow also. I also have it set not to store more than 200 messages from any one user.

This use to happen with my EVO over time and the only fix was to reflash the ROM and start fresh. I am hoping I dont have to do that with this phone as I dont want to spend the time setting everything back up. I seem to remember being able to clear the dalvik cache with my EVO and it helped but I again think that erases most of the phones content, unless I am remembering wrong.

Is there anything I can do without starting fresh or does anyone know why this happens? I am going to go to the T Mobile store but I have little faith in their ability.
 
I don't have this phone, but in my experience, lag is inversely proportional to free RAM.

Check your RAM (in JB: Settings, Application manager, Running). If you've got a low amount (on my phone that number is about 100 MB), then do something about the RAM hogs. Like kill and see if it doesn't restart itself, or find alternative apps, or freeze/unfreeze of you're rooted.

Thanks for the advice. I did try this and it helped a little but the problem still exists. My internal storage is less than half full so I dont think that is the reason.

In speaking with T Mobile they told me with people that use their phone excessively sometimes the phone has to be factory reset. I am guessing that is the only thing that will solve this entirely.
