Battery B.S.

The key difference between this and say the Bionic screenshot....the Display usage. This isn't a phone at rest, its been in use.
 
Display being the top contributor to power usage should be a HUGE clue that this is a misleading screenshot.

The phone in the screenshot is doing little but displaying the screen. If it were handling lots of LTE traffic or even 3G traffic, the display would not be the dominant drainer.

Not only that, but I NEVER trust these battery usage screenshots without a "voice calls" line. Voice calls and display are by far the biggest culprits, and this guy wasn't using the phone part of the phone at all.

That's not always true, on my tbolt display is always on top, not by much but still(also I read they had the screen on full brightness and on the whole time, explains the high level)
 
This is my extended battery btw :-( On the Thunderbolt

Curious. I've had my Droid 2 for about a year now, and I can say two things about it:

1. Display is always at the top of my battery stats - usually by a good margin too - unless on the odd occasion I don't turn my phone on at all in a day.

2. I have had a whopping total of three voice calls on it. I would be extremely surprised if voice was a ever a top contender for battery usage on my phone. :D

Maybe my phone is a hoax too? :p
 
My Droid, Charge, and Bionic, as well as all the other devices I've seen/dealt with, have always had display near the top.

Voice/data will also be big battery drains, but at least for smartphones, other functions which utilize the display, will carry as much weight as actual calls.
 
interesting. seems like the percentage for display varies widely among phones. So I'll stand corrected.

In my experience, CPU and radio tend to hog power the most. Display comes in third. If you're doing web browsing or SMS, for example, most of your time is spent reading or typing, and CPU and radio are idle during these times, but your screen is on the whole time. So the display is actually getting used way more for those activities.

If you stream music a lot, the screen may be off, but the radios are constantly working.

So I guess it comes down to what you do with your phone, and whether you consider those tasks light, medium, or heavy usage.
 
Until the 2nd gen LTE radios hit not one device is going to get great battery life. Mid 2012 we will start seeing better LTE handsets in regards to battery life.

Don't expect it to be anything better than whats already in Verizon's line-up.
 
Running OG Droid OC'd to 1200 (on-demand)....

Display is currently 49% and I've been downloading large torrent files non-stop since last night. The radio only accounts for 29% split 19/10 between aDownloader and Xscope.

Phone is "always" on a dock, so screen is "always" on
 
Even if it was just with display on at max brightness for first a few hours and used constant LTE data three hours as some analyzed, that seems pretty good to me. Also the latest reports from testers are it's good for all day normal usage, 6% drain per two hours. So I remain cautiously optimistic on Nexus battery life. Still there are some confusion on the battery size of final LTE version. But I bet it's 1850mAh at least given this kind of results.
 
I don't understand the premise of this thread. The screenshot was from P3Droid who has had been using the Nexus for the last week or so. He indicated when he tweeted it that he'd been doing heavy surfing at maximum brightness and still had around 45% battery left. So are you accusing him of trying to mislead people, or are you pissed off at Phandroid for drawing the conclusion that the Nexus gets decent battery life overall?

I would say that if your battery indicator shows that the display is the dominant power drainer, you're not using the device heavily. Why? Because CPU and radio eats power at a much faster rate than display when fully utilized.

Heavy surfing means what? That the user is constantly entering in URLs into the browser without taking time to read anything in between? Because that's the only way to simulate high radio usage. While you're actually reading the page, not much is using the battery except the display. So the test might as well have been to keep the display on at full brightness and see how long the battery lasts. You'll find that the battery will do quite well in that scenario.

If that's what you do most with your phone (surf), and you find these results good, then that's great. But I can think of lots of other use cases (I mentioned streaming music earlier) that will drain the battery MUCH faster. And most people would not consider music streaming to be heavy usage.

Therefore I would he hesitant to claim that the phone has good battery life. I'm not saying it's bad either. Just that the screenshot is inconclusive, and the use-case is not comprehensive enough to cover the popular ways smartphones are used.
 
I'm sorry, but I have to partially disagree. The numbers I posted above clearly indicate that even with a CPU overclocked and running at 120

Huh??? My OG Droid Display is always #1 top power user. Always and to me, that makes 100% sense.

Mine is Display 53% right now followed by 15% for Android System.. and this is the norm
 
I also think ICS could help battery life as well.

Also, on a side not

New Corning Lotus Glass that is "rumored" to be used in place of Gorilla Glass on the Nexus "might" help at reducing battery consumption.

So, I think this could absolutely be legit and I am not so willing to just poo poo it because of the crap battery life of current LTE phones.
