Is 'RAW' better than 'JPEG'.......? 'RAW' really drains my battery.....help ?
RAW is the digital equivalent of a film negative, to put it simple. So, yes, it is better than the compressed .jpeg version of an image. RAW basically permits you to change a wide variety of parameters even after you shoot, like white balance, exposure, saturation etc. without damaging the quality of the image. It can literally save an underexposed shot, for example. Think of the tools you use to edit a RAW image like a digital darkroom, if you want. Hope this helps. Anyway, the discussion is much more complicated and detailed than I can answer in one post, I recommend searching for comparisons between the two types of images online for more information. Oh, and the main reason RAW images are so big it's because the are uncompressed.
Anyway, I believe your thread fits into another category
Appreciated......I'm aware that 'RAW' is easier to modify through software.....but you did not address my problem with the battery drainage.....
Is that normal ?

I'm sorry if my answer wasn't helpful, but you first asked if RAW is better than .jpeg and I thought that's what you needed to know. As for your battery problem, I admit I have no idea why is that happening. My camera works just fine in both RAW and .jpeg, so I'm not qualified to answer
Raw will put slightly heavier load on the battery as it takes longer to write to the memory card. The difference is hardly noticeable on my rebel or 50D.
How many jpg shots can you get on a single battery charge? How many Raw?
Works just fine on my 600D, as well. I believe it depends on the camera and/or the quality of the battery pack...
I don't think you'll ever notice a real difference on battery drain.

EnglishBob...Alessya...Vlad....Tks for the comments......RAW will use more power and is easier to work with software.
The reason I 'threaded' the RAW subject was that yesterday I worked out in the back yard experimenting with my new T3i and before starting I check the JPEG available shoots on my 8Gb card and it said about 769 photos....then.....I changed it to RAW and it came down to about 274 (or so).....I must have taken about 40 pics along with myself reading the MENU and wasting precious power on options so I could learn about different options this camera has......then in the short term (about lhr 20min) the battery meter started 'blinking'....Oh Oh....I said, time to return to the house and re-charge.......Hey I'm new a this and all the comments are very well appreciated.....SAKAMOJO
Sakamojo,
By the way - welcome to the group! It is nice to have you here on site with us! We look forward to hearing more from you about your photography adventures! Thanks for joining us!
Sounds like you are not getting a full charge on your battery or something is wrong with it. Usually you can expect several hundred shots per charge. A charge should last a few days at least.
Tks Don......well to ADD to my sorry story, the battery I used was a new one ordered from get this (Made in China)....could be its not good quality......am doing TEST s to prove its me not tha battery.........stay tuned.......

A new battery should be fully charged (overnight if poss) before using. If you part charge regularly, the battery will not hold its charge as long.

It sounds like you're looking at two different issues.
Raw shouldn't be using appreciably more battery power than jpegs. The different numbers that you're seeing on the counter is because the greater information in a raw file takes more room on the memory card, and that number is completely independent from your battery status.
A fully charged Canon battery should last much longer than an hour and a half unless you're consistently using Live View (the LCD screen) for taking photos or video. Non-Canon batteries are another matter entirely – some are just as good, at least in the short term, and others are garbage. The general rule "you get what you pay for" is a hard one to avoid.
'U' got that right Matthew (only get what 'U' pay for)...still, I continue testing things and hope to improve in the 'l o n g' term.
