[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
I thought it was worth starting a thread specifically for data concerning the Skyrocket stats. For other folks posting, OC'd scores are welcome, but please also provide info on your OC frequency. Quadrant scores are pretty good random number generaters, but that's about it. If you want to post them, that's fine, but the variance is so high it's worthless trying to actually use them for reliable benchmarks. Several others are far better. (CF-Bench, Passmark, Antutu, etc.)

CF-Bench is a nice benchmark - only a 2-3% variation in the tests I've done so far, although there aren't any graphics tests unfortunately. There are several posts in this thread with CF-Bench results for comparison.

Monjori really pushes the GPU shader, is repeatable, and doesn't really depend on the CPU speeds that much. Thanks to Da_G for pointing it out.

[Update 12/29/2011] - More Battery Information (T989)

I recently purchased a battery from amazon (based on the comments that it was fully compatible with the Skyrocket.) Samsung ET-CGPK004GSTA T-Mobile SGH-T989 Battery Charger with Stand

The results have been amazing, with over 74 hours of battery life in my first test. Granted this was with light use, but the battery life has been by far consistently better than the one that my phone came with. Has anyone purchased this battery and had the same level of success? I seem to remember having to clear out the battery stats, but once I did, everything worked just fine.

Note that the serial numbers are slightly different, but all of the specifications seem to be identical otherwise. I didn't check to see if NFC was working however, it's not something I'm likely going to use.

Additional details are in post #56 of this thread, but I'll post the screenshot here. (Note that the desk charger I purchased also comes with the battery.)

[Update 12/10/2011] - Battery Information

It's been a while now since I've posted, so I'll try and clean up some of the misconceptions about the battery in the Skyrocket.

The below results are using Da_G's Kernel release 0.3. They are going to be somewhat better than stock, given that I was using both CPU profiles for Under/Over clocking to boost battery/performance respectively, but it was also a fairly high workload with an hour or so of GPS usage while driving, Performance Testing, long screen display times, and so forth.

To cut to the chase, From 100% to 10% Battery, I hit 31 hours in this test. Theoretically I could have received considerably more on another test when I had very light usage (26 hours from 100 -> 45%), I had to charge my phone for a trip the next day so I didn't finish it up.

On to the screenshots!

[Update: 11/19/2011] - CF Bench Scores

This is using Da_G's OC kernel .3 @ 1.782 Ghz. Nice results with a linear ramp up in scores - what you'd expect with a reliable benchmark that mostly factors in CPU. I'm having some stability issues with graphics benchmarks, but there should be a fix out for it soon. I'm not going to bother with Quadrant - just glancing at the Dev thread shows wild variations in scores, exactly the same as what I saw. Gotta love those 1980's apple II style graphics though!

Another nice feature of this kernel is a stable 54 Mhz frequency! This means great battery savings.

[Update: 11/13/2011] - CF Bench Scores, Stock kernel.

[Update: 11/9/2011] - Passmark scores

I was originally going to post data from mobilebenchmark.net showing our results vs. the SGH-I777, then I looked closer and saw the charts were based on one sample. :-) It's a good benchmark, currently in beta, and I'd encourage folks to get it from the market and submit some results. My results were 1660, or 8.2% higher than the OGS2 (based on 41 samples). I'd be interested in seeing what other people get.

This benchmark certainly has much more realistic tests than Quadrant. At least for now the SGH-I727 is one of the fastest phones available. I'm a little surprised we beat them out on the 3D graphics ranking (keep in mind this is still beta software) but at least it's a much more realistic test of what these phones are capable of doing. I'd be interested in the specific score breakdowns here to see how the CPU tests were broken down.

Original Post:

Just wanted to get some benchmark scores and screenshots. If you have the OGS2 and would post benchmarks for comparison, I'd appreciate it. (Screenies as well so all the numbers can be compared.)

Quadrant seemed whacked to me - it was giving me scores all over the place, both low and high.

Best AnTuTu benchmark run: 5956

Some battery history. Basically around 10 hours of battery time went from 100% to 25%. It was fairly idle after 6pm, but I did some moderately heavy benchmarking at one point and had > 1hr at full clock frequency. This was largely at 50% brightness, wireless/bluetooth/gps/sync all on.

I'll grab and post more benchmarks tomorrow.
