Something I have wondered. The Galaxy Nexus runs a TI Omap 4460 processor which is rated for 1.5Ghz at 1.2Ghz. Does anyone know if it's using a lower voltage at 1.2 than 1.2Ghz Omap 4430 phones?
Nope. Seems the same to me.
You can unlock the bootloader and flash new kernels that unlock the 1.5GHz speed, which... doesn't really do anything to the overall performance of the phone from what I can see. The difference is so minimal that I wonder if it's there at all.
---------------------------
That said, having lived with a G Nex for several days, and trying to use it alongside my iPhone 4, I think I can sum it up in a few sentences:
1) iOS 5 is smoother than ICS, or iPhone 4 is smoother than G Nex. That's 4.0.4 running Franco's kernel milestone 2, which as far as I know is the latest of its breed already.
2) ICS is more convenient than iOS 5. Unlock once and all of my toggles are there. Quick tasks are done quicker on ICS. No contest. If "Smoked by Windows Phone" was still around, I would smoke them in ALL of the challenges. Tasker is highly critical here.
3) iPhone 4 with cellular network on has 3 - 4x better battery life than G Nex with only WIFI on, and the difference is still 2.5 - 3x with the extended battery pack on the G Nex. I have done every tweak possible that XDA suggested, and also tested undervolting. There is just no way around this. Seems more like an OS issue than radio issue (since there is no 4G/LTE sim in my G Nex). Well, at least now you won't have to blame 4G for bad battery life. I firmly believe some software updates may fix this, though, since I've noticed different ROMs give different battery life (worst case had the G Nex drain 30 - 40% in 1 hour just browsing the web)
4) Flash on G Nex runs a hell of a lot smoother than I expected. In fact, I don't think Flash affected the performance of the browser at all. It may drain battery life, but hell, now I have full desktop browsing (save for Hulu) in my pocket at acceptable performance, so I wouldn't mind losing battery. It's not even a "phone" to me right now anyway. I'm a Flash developer myself, so this is a huge plus. iPhone 4 doesn't support Flash, and I think you can draw the conclusion.
5) I have a ton of apps and games on my iPhone 4, I have... a ton of widgets on my G Nex right now. Lack of G Nex apps is quite... perplexing. Random things like storing Wikipedia database offline is still done in a manner that's not quite as elegant as I would like. Sure, it cost money on the iPhone 4, but... it works, and I can accomplish at least something. Also, some widgets on G Nex look like hell. It was fun blaming the devs last year, though, but it's getting old, and obviously the OS itself still has minor flaws (see above), so... I'm placing the blame on this one on Google as well.
6) I have learned to test my apps on the G Nex wirelessly over WIFI, so I don't have to plug the device into my MacBook anymore. Mighty neat stuff! I still have to plug my phone into Xcode to see debug information, and I haven't found any solution to do it wirelessly. Also iPhone development is a bunch of crazy certificate management. Not really all fun and games.
7) iPhone 4 screen looks sharper than the pentile SAMOLED screen on the G Nex. iPhone 4 has imminently more natural and accurate colors than the G Nex (note: my G Nex also has a yellow tint, but I'm not basing my assessment on just that). At low brightness, SAMOLED on G Nex exhibits annoying visible artifacts that look like someone slotted in a crumpled piece of paper underneath a transparent display. Calibrating the display helped at slightly higher brightness settings, but at the minimum brightness settings for night reading, the G Nex is nigh unbearable with a white background. Sadly, most websites I visit have white backgrounds (like this one). Conclusion: white is bad on G Nex, black is bad on iPhone 4, but not as bad as white on G Nex. BUT (big but) as far as auto brightness go, I'd rate ICS at 11/10 and iOS 5 at -1/10. It is THAT bad. I can only slightly tolerate it by jailbreaking the phone and installing a tweak that allows me to constantly adjust the brightness slider manually. Other than that, I would NEVER use an iPhone without that jailbreak tweak.
8) Camera of iPhone 4 takes more grainy photos that don't lack details. Camera of G Nex takes smoother photos with a bit of details lost but... I prefer G Nex's photos. Neither phone holds a candle to the 4S, either way, and I would use the iPhone 4 more because it's more convenient to pull out of the pocket. G Nex's larger size puts it at a disadvantage here.
9) More a jab at Samsung than at Google: the charger brick and USB cable definitely took design cues from Apple.
10) Overall, I'd say... I prefer iPhone 4 as a phone with more advanced functionality, and G Nex as more of a miniature limited computer terminal. Both are fun to play with, and I can't believe I'm saying this... but... I finally understand why Joshua Topolsky of The Verge carry both a G Nex and an iPhone 4S at any random time. That's exactly what I'm gonna do, and I won't miss out on anything of either side.
And that's it.
