If you'll need to have a screen captured on your T-Mobile Samsung Galaxy S2 (S II) SGH-T989, that's too very easy. You don't need to have it rooted or install any software tools or screenshot capture application just to have a screenshots of your phone.

You can directly take a screenshots right away from your device because the Samsung Galaxy S2 is already has it's own built in screen capture function. All you need to do is just - by pressing the HOME button and then quickly press and release the Power button. (you have to push the power button quickly because the task manager comes up if you keep the home button pushed too long)
The taken screenshots will then be saved on the phones image gallery folder.
This will also works on AT&T Samsung Galaxy S II SGH-I777 and Samsung Galaxy S II I9100 (global version). This is how tech bloggers and developers do when they want to share a screenshot sample of their newly develop android themes or custom ROMs out over on the internet.

If you had experience and somehow had trouble with the rapidly draining battery of your Samsung Galaxy S2 (SII) by AT&T. In most recent reports that the new AT&T Samsung Galaxy S II had a poor battery life.
Others says that this is due to a poor system OS or some bugs issues that one of the main reason why your phone drains its battery so fast.

So, how to get your Samsung Galaxy S2 I777 improved the battery life performance?
Here's a few tweaks we gathered so far and shared by Singuy1234 who already had his Samsung Galaxy S2 battery life problem fixed.

My phone is no longer draining massive amount of battery life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.

My fixes.

1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory

Yes, att installs a lot of bloatware that constantly update for changes.

If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:

1. Take phone back to AT&T and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here

OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).

You can read the whole story at XDA-developer. We'll hope that Samsung will release a  new firmware update that fix for this battery draining issue a soon as possible.
