I think it was more like the 1st gen LTE kills battery life (Galaxy Nexus). After the 2nd gen came out, I had no fears of moving up to LTE.

Exactly. With 28/32 nm LTE available, there is no excuse for its absence in mid to higher end North American smartphones, in 2012 H2 or beyond.

No, phones that don't have a removable battery are supposed to have better battery life because they can (but often don't) put a bigger one in there.

Look at the first two charts, the S3 is better. Then somehow in the 2nd (iPhone review) chart the S3 suddenly loses 2+ hours.

I don't think AT is fudging the numbers, I just think their battery testing methodology is odd and don't really trust it (or any site for that matter. Battery life tests are best done on your own)

Yeah but I can't believe any of that. Even as a methodical engineer, I'm not comfortable in saying I device A is better than device B in battery life.

Everyday's use is different, and stuff varies. And plus, with idiots on XDA whining "omg the new nightly DRAINS battery like mad. please fix" on every other nightly when no kernel commits have even been added, I can't believe anything AT ALL.

signal strenth,apps running in backround and screen brightness can change results by more than an hour!

Okay, but Anand has controlled testing. It's better controlled testing than you and I could possibly ever run unless we get a bunch of equipment and we have a month of free time to mess around.

The thing is I don't think that any of the phone manufacturers obsess about z-height and packing as much crap in as Apple does. It's been this trend since the iPod and even Macbooks. Their devices are small and they have some insane cramming abilities.

Yes ideally if you go nonremovable you should have more volume for a battery, but unfortunately I don't think these companies optimize their internal layout as much as they should. Why else do you have creaky crap and hollow areas?

Isn't this because of 2nd gen LTE? Why is it being compared to first gen LTE devices?

Because tons of people have the older devices and better battery life is a huge selling point for the new ones. So being able to give relative ideas about how much more efficient the radios are and how much battery life that will save them is important.

there's a lot of first gen LTE devices out there that do fine too. i seriously don't think it's just LTE.

The Galaxy Nexus sucks even on 3G HSPA if you look at the GSM version. It's something fundamentally wrong with the power efficiency.

The Nexus S sucks too. How does a Galaxy S2 do so much better? Sure battery is like 10% better, but it's more than 10% better in battery life. The minute you load up a custom kernel and ROM, you can tweak the hell out of battery.

These phone manufacturers do that. The Nexus phones seem to be lacking sometimes.

Galaxy Nexus has better battery life than Galaxy S2.

I can't think of one LTE device that uses a 1st gen radio(excluding the Droid Razr Maxx of course) that has anything other than what can be described as atrocious battery life. Lumia 900, Galaxy Note ATT, Galaxy S2 Skyrocket, Thunderbolt, Bionic, Razr, Rezound, Galaxy Nexus all come to mind as phones with poor battery life if LTE is enabled.
 
I thought other LTE phones had 3 antennas while the iPhone 5 had 2 antennas. This saves power but doesn't allow voice/data (currently since VoLTE is not up yet) on Sprint/Verizon networks.

I think android phones and iPhone have 2 antennas, but the difference is that the iPhone uses two antennas for LTE OR CDMA, where an android phone will use one for LTE and one for CDMA.
 
My understanding is that it is a requirement in the LTE specification to have 2 antennas working for LTE; all Android LTE phones use two antennas when LTE is enabled
