Samsung Galaxy Nexus Unboxing & Hands-On

http://www.youtube.com/watch?v=4ne8eaaGTdg
My unboxing of the Galaxy Nexus. Really liking this phone so far! Coming from an iPhone 4S and Nexus S, the GNex is unlike anything I've ever used. It definitely has the best display I've seen so far, slightly beating out the iPhone 4S. Hope you guys enjoy! If you want to see any specific videos let me know on here or on the video comments!

nice vid!.
thanks for posting

Love to see some battery results, especially battery drain while idle over a few hours (simulate a work day, gmail going, wifi off, 3g connected)

I took the phone off the charger when it got to 100% about 45 minutes ago. Now its at 80% but I had force hardware acceleration on. I really hope the battery adjusts and gets better because a 20% drain that fast is a little ridiculous.

The first few charges/discharges on Samsung batteries work wonders for battery life.
My Nexus S and SGSII had terrible battery life on the first few charges. Was concerning. After those initial cycles, the life was so much better. Got 2 days 16 hrs on my SGSII just prior to my GNEX arriving this Friday morning.
The GNEX is on 11 h 50m now and has 25 minutes left. Charged it when FedEx delivered it at 11am mountain today. I'd say that's pretty great as I've been using the hell out of it since it arrived. I expect subsequent charges to add to the life and am not worried one bit about getting a full day out of it (par for the course - it's not a flip-phone).

Is your Galaxy S II on the stock kernel/rom? I can't wait to install a custom kernel on this bad boy. Developers are saying the stock kernel really isn't that good. I'm also noticing a good bit of heat generating from around the camera during normal usage.

Haha! nice video, I'm actually subscribed to your channel and, saw it earlier. You said you had to manually turn on hardware acceleration, is that done in developer options in the settings?

@nikolaittt TI's spec says anything up to 83 (celsius) is okay for normal operation (according to commits in the kernel). These things run very hot.

Is it the "Force GPU rendering...Use 2D hardware acceleration in applications" setting? That doesn't sound like hardware acceleration...it sounds like a setting to force apps that aren't ICS coded to run faster. Or maybe the OS is hardware accelerated but apps aren't?
Why would hardware acceleration be disabled out of the box? That's one of the most anticipated features of ICS...

It isn't disabled by default. The entire OS and all ICS optimized apps are hardware accelerated by default. Older apps that haven't been optimized for ICS may not have hardware acceleration, so there's an option to force it until the developer optimizes the app for ICS.

Arcadia310, I really liked your video! I just got my galaxy note like a week ago, and love it. I was deciding between this and the nexus as they were about the same in price. Anyways, you mentioned toward the end of your video a comment about the hue you noticed on whites on the display. My note has this slightly greenish hue when looking at whites anything but straight on. Is that what you noticed?

Thanks! On medium to high brightness, whites look okay. I want to say mine have a slight reddish tint but its so faint that it won't bother me. All displays have some kind of tint. On low brightness whites tend to look a little grainy but its nothing to stress about.

Right now the Galaxy Nexus, mainly because of the screen and ICS. It'll come down to battery life though. If I can't make it through a full day on the GNex I'll have to use the iPhone 4S.

[Q] Increase Battery Life

Flash my ROM (see sig)

did u try calibrating the battery with any of the free software on the market !
i used to get 3 hours "seriously" out of this phone ... after deploating and calibration it can last 12 hours with heavy use !

I've started using an external battery charger (one of the official lg ones from Ebay) and an extra battery, and just swap them out when my phone dies, and I've noticed on the few occasions where I charge my phone by plugging it in, even though it says 100% (and I've done all the battery calibrations and everything) it doesn't last as long as when I pop in a fully externally charged battery.

My device battery life also got better in comparison to the first days i used it. But for some reason i experience some strange usage right now.
For example:
In the morning from 7 - 10am 100%... later 10% in 15 minutes, with phone in standby-mode.
I checked after i'd make a phonecall, hardware consumption for radio was on 99,9%. After reboot it was ok again, but later hardware consumption for the screen was at high level. Strange... everyday a new experience.

Turning LTE off helped my Spectrum last 24+ hours. I turn 4G on whenever I really need it, though. And with 4G on all day, I can get 12-16 hours under moderate use.

+1, better battery life than stock ROM

I have honestly never seen a phone go through battery quite like this one. I love the phone to death. It feels solid in the hand, and the screen quality is amazing. But I can't deal with the battery going like this. I input a new APN so it would just use HSPA+ .. but does that actually stop the LTE radio from searching? (I am in a non-LTE area)

Yes our screens are a big consumer of power but there are plenty of disadvantages to AMOLED: heat, image burn (like a plasma tv), image quality and longevity of the screen. The more pixles that are lit the more power it uses, to the point that it uses more power than IPS with large areas of the screen are lit. This along with image retention is why CM7/9/10 has black as a background for everything and stock doesn't. Think of it as LED/LCD TV's vs Plasma. Similar power curves between them.
BTW the little program above dropped my idle power usage to only 5% over 8 hours. I will be trying it with cm10 to see if I get similar results.

Maximum brightness eats up my GNex battery. Normal?

After I changed it to minimum setting, my GNex survive from morning until the end of work without charging at all and it's still have 56% battery (normal use: up to 50MB data download, messaging, one or two calls, 9 hours or more screen time).
Is it normal that brightness is the most heavy resource eating the battery?

Um... yes.

9 hours and still 50%+ is also a blatant lie unless you have a 812948712mAh battery ducttaped to the phone...

I can get 9 hours of screen time no prob! (if my phone is plugged in the whole time) :cyclops:

Just look at your battery life report after 1 day of usage. Its blatantly clear that the screen is the biggest battery drain on the device.
Also calling BS on 9 hours of screen on time.

Yeah I think he meant... 9 hours overall not screen on time. That would only be possible on 0% brightness on a black screen.

Dude that's first-day stuff. Brighter the screen = more power being used. Avoid auto brightness too, all that constant adjusting of brightness is no good for your batt either. Just toggle it as needed :thumbup:

Or if you have one of those roms where you can slide your finger across to manually adjust the brightness when needed, it helps save a little on battery life. But the days when you could just check the auto brightness box and be all good (ics) are no more now that jb is here. Even with that checked, you still have a screen that's bright as heck and devouring your battery.

I can't relate to any of that. Auto-brightness is fine, always has been. And there is no difference in screen brightness from ics to jb.

I read almost everywhere that auto brightness is not good for battery but never tested it.

May have to do with the sensor. I've never liked auto brightness, personally. I usually set mine at like 30% during the day and 0% before I go to bed.

Battery Drain

It all depends on how you use. Use it a lot and always have the screen on it's going to go fast. I have a friend who can get a couple days off her Ion.
Let it die. Plug it in, leave it on the charger until it's full. I did that and noticed a HUGE difference in battery life.

Ya mine varied quite a bit by rom too.. I had fantastic life on my atrix with a customized version of CM7.2.
Ya thats true, i actually resorted to looking at quite a lot of reviews and run down tests and ive never seen so many mixed reviews haha... some said it was terrible some said it was solid.

It all depends on how you use the phone my Sk17i (Xperia mini pro) can make through 1 day by draining at least 5% without using it (custom Rom obviously xD)

[Q] Battery life with that display.

I am thinking of buying the G3, my only concern is the battery life.
Does the monster display's resolution affect the battery life much?
How much on average does it last and how much does the brightness affect the battery life.
Thank you!
PS. Sorry for my English :/

Search on Google, there are plenty of reviews covering battery life as well. Briefly, "surprisingly good" according to most of them.. not worse than competition (Z2, M8, S5) but not as good as its predecessor G2, means that it is good enough.

Truth. Really depends on the bootloader situation. Fortunately, it's nice that the root is available--at least debloating the phones of preloaded junk can be done.

Its actually better than the S5's battery and my HTC Butterfly S 3200mah battery.
I can easily last 2 days using the LG G3

I had all three phones I would say the htc m8 is the best ,the g3 would be about 92% of the htc and the s5 would be 85% of the htc.
