[HTC Rezound] Purpeltendire:
DanceDance vs Wheatley vs SmartassV2

Without further delay, here is the comparison between Wheatley, DanceDance, and SmartassV2. I'll go through each governor at a time, and post the data along with each writeup. A lot of what I say may be repeated in the original posts for each governor, so bear with me. :)

Notes: Scheduler was Noop.

My usage habits: If there is WiFi, I turn data off. Screen is bright outside, and dim inside, using manual slider and not automatic.

Voltages

Percieved performance did not have much variation. All three governors lagged using Chrome at first, because Chrome sucks. And all three governors performed about the same at pretty much evevrything else, as far as I could tell. No actual benchmarks though, sorry. If you guys want to see benchmarkingg as a comparison I could do that using AnTuTu or another app if suggested.

First up is SmartassV2.

Smartass 1

Smartass 2

Smartass 3

Of the three, I think this one was the happy medium. The battery discharge curve seemed reasonable, I got slightly under two hours of screen on time, and had about 30% life left when I finished my day and took screenshots before plugging it in. As I said before, my favourite part of this governor is that it doesn't spent much time at all at 192 MHz, it just goes straight to Deep Sleep. If it didn't have this, it probably would have performed far worse.

App usage was pretty standard today, and screen usage was a little on the bright side -- I grabbed lunch and sat outside to enjoy weather and catch up on some XDA posts this day, so I cranked up the brightness.

Overall feel was very smooth, with the exception of Chrome as usual. I hate that browser, but it has nice gestures and all my desktop bookmarks...

So. SmartassV2 places Second. Good battery drain coupled with good performance definitely make it a go-to, and given the "direct-to-deep" CPU Usage, it's a very good choice for someone who uses apps on and off throughout the day, as opposed to someone who just uses a few things and texts.

Next is Wheatley.

Wheatley 1

Wheatley 2

Wheatley 3

I was pretty surprised when Wheatley came in last for screen on time and battery life -- after all, Wheatley and Row is an undisputed set up for good battery life. But, my usages were very similar to Smartass. It spent an hour more being turned on, and 5 minutes less using the screen. Yet it had a 15% difference in final battery life, which is considerable.

It might have something to do with the fact that the phone spent nearly 3 hours at full clock -- all the screen on time plus all the "PowerManagerService" time. PMS, if you'll pardon the abbreviation, is all partial or app-specific wakelocks rolled into one listing.

There was no frequency shifting here, just getting tasks done as quickly as possible before returning to sleep.

No variations in performance; I think that from a noticeable performance perspective, these three governors are very very similar, which makes me focus on battery life.

Last, but certainly not least, is DanceDance.

DanceDance 1

DanceDance 2

DanceDance 3

As far as screen time and pure battery life goes, DanceDance is king. 'Nuff Said. I got a little over 20 minutes more time with the screen on than in Smartass with nearly the same battery percentage, and close to 30 minutes more compared to Wheatley with 15% more juice left over. That's significant, especially for people who use their phone to do research or typing.

**Note. During screenshots, battery usage per hour were the same for Smartass and DanceDance, at 4.2%. But right when I plugged it in I checked again, and DanceDance had gone down. Here is another screenshot as proof.**

CPU usage was good, DanceDance has a nice ramping system. Interestingly, this governor, while achieving the best battery performance, also spent the most time at 192 MHz compared to the other governors.

Here's my conclusion.

If you're a user who tends to use a large number of apps, and you do a fair bit on your phone, I'd go with Smartass. It does a great job coming down from utilization, and saves the cycles for when they're needed.

If you're just looking for pure battery performance and looking to squeeze every last drop of juice from your battery, I recommend DanceDance.

I cannot recommend Wheatley for anything at this time; my testing didn't show it to do anything better than the others. Maybe it's a bit better on a benchmark; I can't be certain.

Hope you all enjoy the read, sorry it's so long. Have a good one!

Scary governor tomorrow.
