Battery Life

I don't want to ruin the moment... but any info about battery life on Nexus 4?
I don't want to waste ~u$s360 with a device that longs 4/5 hours...
Thanks.

And how are we supposed to gather this type of information?
Wait for hands on reviews!

According to gsmarena, it has a 2100 mah battery

Yeah, the big downside of a non-removable battery is the inability to upgrade if the battery life sucks. I can go over 24 hours on my Sensation with moderate use thanks to the extended battery I purchased for it.

It's a far cry from the GNexs 1750mAh battery, the 2100mAh battery in this should last a little longer.

I heard somewhere (for the life of me I cannot remember where) that it has somewhere around 12 hours talk-time. Of course that's yet to be confirmed...

well your basically getting a gnex with 350mah extra battery. and this time they are using a Li-polymer battery instead of the normal Li-ion so the battery will not degrade in about 2 years it will still hold a good charge.

anything's better than the iPhone 5's 1700 mAh batter

As seen in the pdf manual, there are only two little screws keeping you from removing the battery

1440 mAh.
That said, it's not only about mAh -- the iP5 holds pretty close to the Maxx from a lot of reviews.

Exactly. But Android phones, particularly the high-end ones, require an added boost. The iPhone 5 doesn't need the extra battery power; Apple have been very clever when it comes to power consumption. It's impressive.

I took a review concerning this topic:
http://www.phonearena.com/news/LG-O...-Galaxy-S-III-claims-an-LG-experiment_id35585
LG Optimus also has 2100mAh (I know, doesn't have to be same manufacteur) and the same components and it has a really good battery life.
Always better than S3.
+ LG says that their battery has more charging cycles. In the data sheet of Nexus 4 and Optimus G it says 800 instead of the usual 500:

+ (OT) really flat display so you don't feel the distance of your fnger to the screen (same source)

Nice!
2100mAh should be pretty good, especially without LTE.

One other small thing to note, the battery is a bit higher voltage than your standard cell. 3.8v vs 3.6v, so that works out to 7.98Wh vs 7.56Wh.

Mine was giving me about 36 hrs with moderate use on ARHD ? Like a year ago ? Besides this phone will have so many kernels and rooms to choose from in like a month or so that will help you get better management of it that I just don't see it being an issue ??? And chances are you might not even have it after two years when the battery starts degrading ...

15.3 hours of talk time or "up to 10"?

I'm really confused by Google about this.
Various websites (including androidcentral and androidandme) show google's press release to show that the phone has 15.3 hours of talk, and 390 hours of standby time.
But Google has told the verge that it will have "up to 10" hours of talk time.
Then my friend found this: http://support.google.com/nexus/bin/answer.py?hl=en&answer=2840740&topic=2775467&ctx=topic
Which essentially says "up to 10" hours of talk time, and 250 hours standby.
If that is the case, and it looks like it is, I am disappointed. With my OEM 2000 Mah battery in my Galaxy Nexus, I can also obtain about 10 hours of talk time. So then that leads me to believe this Li-polymer battery is no more efficient than the regular li-ion that we have currently...and most of all, I don't see how the phone's crappy "screen on time" (which is a measely 4 hours on mine) will improve.

It's not how big the battery is that determines the length of time it takes to drain it. It's how the battery is used. We have to wait for reviews before making judgements.

What's the point of speculating? I've never seen any device's battery last as long as the product data sheet says it will. Once the phone is more thoroughly reviewed we'll have a better idea. Even then, the battery life is completely relative to how it's being used.

I understand what you're saying about relativity to use, but ratings have to have some stem of truth to them, and even if they are inaccurate, they are measuring points.
The point is, they rated the Galaxy Nexus's original 1750Mah battery at 8 hours of talk time.
They've rated this phone's 2100 mah battery at "up to 10".
1750 is 83% of 2100 mah. 83% of 10 hours is 8 hours and 19 minutes. So if in fact by their measurement, the new li-ion-polymer battery in this does only yield "up to 10" hours of battery life, then it's not any significantly more efficient than the Galaxy Nexus' batteries.
In the press releases that all the android websites have seemed to have recieved, it says 15.3 hours of talk time. If that is true, that means this battery is 63% more efficient. That's HUGE. So it's not something to be glossed over. Something is not right. And honestly when I first read those press releases, that made me very excited.
Androidcentral did a poll and found battery life to be at the top of people's concerns with their phones. So this is definitely relevant.
With that in mind, I'm guessing a lot of people, like myself included were hoping for an increase in our screen on time, and now I'm pessemistic about that.

Battery life should be comparable to the one of LG Optimus G (battery is from LG, too, and it is stated, like for the LG that the charging cycles are 800, instead of the usual 500). Hardware is nearly the same.
http://www.phonearena.com/news/LG-O...-Galaxy-S-III-claims-an-LG-experiment_id35585
This experiment was made by LG itself, so it isn't confident but I believe that it could be around 15hrs.

I agree that battery life is a huge area of concern for Android users, and I too hope that there are improvements with the Nexus 4 over the Galaxy Nexus. My point is that the variance in how these devices are used from person to person, what types of applications are running, signal strength, etc makes a numbers like 15.3 or 10 hours of talk time generally moot.
Given the extremely limited amount of information to work with due to so few in-depth reviews being released at the moment, we need to wait and see. Will we all see 15.3 hours of talk time? Probably not. Will it be better than the Galaxy Nexus? I think it will, but how much better remains to be seen and will vary.

I hope you're right, that it is better. Of course I don't actually expect the battery to be a whole 63% more efficient, but I hope that there is some truth to it being more efficient. Maybe 40% more efficient?
The implications could be very good if it's true, because LG is also claiming that this screen is 60% more efficient.
Now let's look at it another way:
If I can get 4.5 hours of screen on, on the Galaxy Nexus, then if their claims were fully true (which we'll know is not the case, but let's look at it for fun's sake)...then 4.5 x 1.63 (63% more efficient battery) x 1.60 (60% more efficient screen) = 11.736 of screen on time.
Is that realistic? I HIGHLY doubt it.
What if their claims were somewhat true?
Let's say it's only 40% for either:
4.5 x 1.4 x 1.4 = 8.82. That's still something I would love.
Is it a pipe dream? Probably. But one can dream.

OP you're not comparing apples to apples here; the Nexus 4 is completely different hardware so trying to compare the efficiency of the different battery technologies is a pointless exercise.
trying to do math when you've got the underlying assumptions wrong will just yield wrong answers.

Why dont tech world give first priority to battery capacity for smartphones?

its all about resolution or processors or gpu , what is all those big numbers worth without big battery, 5 hours of screen time with moderate use and your so called beast dies. most of the leaks first give idea of processor ,screen, resolution, ram but not battery capacity, may be its because battery capacity isn't that important in the eyes of most. 5 inch screen should have 3500 mah battery life droid razr maxx and 5.5 should have 4000 mah. if they say mobile gets thicker with bigger battery , lenovo gave 10mm 5 inch smartphone with 5000 mah , and 6 inch vibe z2 pro with 4000mah even with thin 7.7mm profile. im a heavy user like most , and i dont want to replace the battery mid day. im not an iphone user only to show off my device. i want substance as well.

Buy a cover like this http://www.amazon.com/gp/aw/d/B00JCFETQ0?pc_redir=1409107931&robot_redir=1

Powerbanks
I think It's the Software/OS that's power hungry, so packing a higher capacity battery is not their priority. Take a look at the HTC One M8 for Windows, they claim that the battery lasts 20% longer than it's Android counterpart. What they should prioritize is optimizing the software's power consumption.
Getting a powerbank is a good choice... for now... until Android L arrives.

Its about software/os just like tunichi01 said and they also want to slim the phone most of the times so they are putting an average battery in it just like most manafactures also have in mah anmount. So its also the phone's design from inside and the outside to fit the batery. And for most users the 3009 mah battery is enough, I had an nexus4 with like 2200-2300 maH I believe and that had 6 hours sot that was enough for me and the most average users. Biggerbattery could also risk an explosion if the phone isnt good designed.

Note 4 battery anyone concern?

I had the note 3 the battery was terrible and i really thought we'd be getting atleast 4000mah as some websites stated but 3220mah aren't you guys concern? Seems like a joke to me.

I was under the impression that the Note 3 had pretty good battery life... at least that was what I was able to discern from reviews.
Can someone else who also owned the Note 3 chime in?

Watch this and you won't be concerned about battery any more:
https://www.google.de/url?sa=t&sour...Ot9BGMeI02GwNY_Zw&sig2=jB_BFvUf5EMKyJdT_ZwXOw
This video shows that the Galaxy S5 with Snapdragon 805 and QHD Display doesn't use more battery than the "old" Galaxy S5. So Samsung seems to have found good ways for battery saving.

I am not concern. I plan to get 2 extra battery and a external charger. The Note 3 version was like $30. Whick brand is good? Anker?

You would be correct. The Note 3 Battery life was pretty damn good. I never had issues with it, and if you look over the N3 forum you'll see some pretty outstanding results :good:
I expect the N4 to have been tweaked a little and the battery to be either on par or at least very very similar to the N3.

The Note 3 was widely regarded as having some of the best battery life for any phone of that time.

If anything wall hugging iphone users have something to be worried about with their copycat device, "Retina HD" welcome to 2012 Apple and the battery size, hardly a mention because we KNOW its smaller than Samsungs.

My note 3 has pretty decent battery life. Just make sure to disable a bunch of stuff that you don't need for best results.

since 4.4.2 update WiFi battery usage increased. so i got battery drain...
But i change setting to turn off WiFi when screen off and Battery Life became normal
On Note 4 they claimed for more optimization for power + UltraPower Saving mode...
so we have to wait for reviews and our experiences...
:good:

Even though I was disappointed they didn't include a bigger battery, I'm not concerned about battery usage on Note 4. I don't think they would've made a big deal about battery usage the and better performance on the Note 4, if they didn't have something to back that up. It would've been much simpler to not mention the 7% improvement, or just say they increased the battery by 20mAh. I'm expecting a somewhat better performance compared to the Note 3, which is fine.

The battery is still bigger than the iphone 6+'s and you can always swap it out and with quick charge feature 0-50% in 30 minutes, how long does an iphone take?

It's not how big the battery is, but how it's used. I have Note 3 and I saw as much as 40% drain overnight, when phone was not used at all, right after updating to KitKat and I also managed to have as little as 1% drain overnight, after killing some of bloatware. I can't pinpoint anything in particular, but it could be more than one program. Right now for example Google search is draining my battery more than all other programs combined and I'm not doing anything with the phone at all. I don't want to kill it, since I use it sometimes, but if it keeps doing it I may have no choice. Anyhow if Note 3 is working properly it can have fantastic battery life.
According to what I read so far Note 4 screen should be something like 14% more efficient than older version, despite having higher resolution, CPU and rest of hardware should be at last as good as older models and there should be ultra power saving mode, so I wouldn't worry about power that much, unless some program or programs crash and go bananas, but at least software issues can be fixed, just a matter of effort. For example many claim factory reset fixes excessive battery drain right after firmware update, which I had personally.

If you are concerned, you could always buy a ZeroLemon battery.
Here's the report on Note 4 screen. Remember display consumes the most energy of anything.
http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm
Comparison with the Galaxy Note 3:
The Galaxy Note 4 is 14 percent more power efficient than the Galaxy Note 3. This is due primarily to a 19 percent improvement
in the power efficiency of the Green Primary channel (materials and electronics). The results are scaled for the same Luminance.
Comparison with LCDs:
While LCDs remain more power efficient for images with mostly white content (like text screens, for example), OLEDs are now
more power efficient for mixed image content because they are emissive displays so their power varies with the Average Picture
Level (average Brightness) of the image content. For LCDs the display power is independent of image content. OLEDs have
been rapidly improving in their power efficiency. In fact, the Galaxy Note 4 is 40 percent more power efficient than the
Full HD LCD Smartphones we tested for mixed image content (that includes photos, videos, and movies, for example)
with a typical 50 percent Average Picture Level, APL.

SOC should use the same power as other Snapdragon 805 powered devices (hint: Qualcomm generally makes pretty power efficient smartphones).

S8 vs S8+ battery life comparision

Anybody find any links to S8 vs S8+ battery life comparison​? I want the S8 for size in my pocket and easy to reach fingerprint scanner. Want to see tests of the S8 vs S8+ vs S7 Edge battery life comparison...

I cancelled my preorder to wait for battery life reviews, bigger screens and higher resolution and same sized battery (smaller for s8+ than s7e) doesn't seem like the processor will be able to offset the drain. And also wondering if the exynos will be more efficient with battery life than sd as last year was. I use to have sd820 s7e and now I'm using international exynos s7e and do wish I originally bought the international one

Phone arena did some testing and found that it comes out on top over the S7E. It also beat the Pixel XL and Oneplus 3T. Of course people need to do there own testing to be sure.
It's not just the SoC being more efficient that can save battery. Displaymate.com have noted that the panel is not only better but also more energy efficient. The software is no doubt better optimised and that can also mean battery savings. Anyway, in the tests in ran for 8 hours which isn't bad. Add fast charging and it's fine for most people.
Next time I do hope they increase capacity, I don't want slimmer phones, I would prefer a larger battery. We never seem to benefit from improved power efficiency, it's always more of the same. They have supposedly improved the battery tech in the S8, it should hold charge better over time. We might only lose 5% over a year instead of 20%. That is better in the long run.

I think they purposely made the battery small to prevent the chance of phone explosion, that is absolutely the last thing they need right now and I don't think they want to risk that., but I'm rooting for the s8/s8+ to have great battery life. I'm hoping the battery stats r near identical between the two models so I can get the smaller s8 and not feel like I got jipped on battery life, and I read some early test that the 8895 exynos will be better than snapdragon.
