[Q] battery life comparison exynos vs snapdragon? - Galaxy S 4 Q&A, Help & Troubleshooting

Are there any comparisons of the two cpus available on the s4 when it comes to battery life? Thats the only reason for me to try to get an exynos version if its shows to be better in that respect.

Yeah, that's a good question I want to know the answer too, there are many people having testing devices but they are too hungry about testing the damn processor and gpu instead testing properly the battery life. -_-

Lord knows battery Life is very important to me.

the guy that's testing whatever people tell him to test said that when his battery got down to 30% it lasted like 3 hours with max brightness and benchmarks running

With wich cpu? Also no comparison to the other version mentioned here.

I'm not convinced, even with S3 you can spend all the battery juice in 3 hours if you want. To do a proper test you need to leave the device doing the same job like an Snapdragon S4 during the same time.

Octa has a longer battery life than SD600.
That's why samsung used 8 cores technology.
And by the way the 5inch HD screen saves power too for both version

Thaty what one hears, yes.
However I would like some actual test reports - for instance how long does the phone last for web browsing, for video playback and on standby?
I would like to see actual numbers.
As for the screen:
It is said to use 25% less power compared to previous amoled display generations. However that 25% value is something we have to trust samsung on I think, at least I have not seen any actual tests on power consuption of the display alone and it's probably not easy to test.
The way they have managed the display to consume less power is to use use phosphorescent instead of fluorescent green diodes, which use way less power. Until now they could not produce the green ones with an acceptable lifetime. The red ones have already been phosphorescent, and the blue one are still fluorescent since they are hardest to produce.

This. This so many times over.
So many people are parroting the "Exynos will have better battery life" thing but this really remains to be seen.
If the better battery life is in exchange for crippled A7 performance at inconvenient moments then it's useless. If better battery life isn't available for when you're using intensive apps then it's also useless.

Battery life is GREAT, until you use it?!

This is not another thread about battery life obsession. It's more about a curiosity.
I have my Evo tuned so that it has great battery life on standby. When I use it for anything--SMS, data, local apps--the battery drains very fast.
I know that data, CPU, and display are the major consumers, but...
I have a Nexus One, with also a 1Ghz Snapdragon, and almost exactly the same loaded apps. Same screen resolution, both on 2.2. Both have 1500mAh battery. The only difference is the display technology and radio (GSM/EDGE/HSPA vs. CDMA/1xRTT/EVDO).
When used equally, the N1's battery does not drain nearly as fast as the Evo. How come? I know AMOLED is supposed be more power efficient, but by that much? I know CDMA can be less efficient, but again, by that much?
- - -
Duh! Edited from Hummingbird to Snapdragon (got confused-I just picked up an Epic which has Hummingbird). Thanks for correcting.
They both use Snapdragon, Hummingbird is Samsungs CPU codename, it's based on the same architecture but uses a smaller process.

Is it something new, or has this always been happening?
Was it after the new update or kernel WHATEVER, that you flashed?
If you’re running the stock kernel, do you think the fact that the screen is physically bigger may have something to do with the difference? I’ve always accounted the difference in the battery drain speed (between screen on and screen off) to the fact that most of us are running tweaked kernels that are overclocked when the screen on (with 5 point multi-touch, etc), and underclocked with the screen off.
The problem with battery life issues is that most of the time it can be just a perception and not scientific evidence at all.
Personally, I had an iPhone 3GS prior to getting an EVO and I would say the same exact thing happened with my iPhone. Especially when I was playing games. It doesn't seem to happen with my EVO.
Even seemingly silly things like the Battery Icon can help with the perception that battery life on the phone is bad. Since it only has 4 levels, it kind of tricks your mind into thinking your battery is draining really fast. Try flashing this.
Scientifically, The difference in battery life running the same exact apps under the same exact conditions would be almost negligible between an Evo and a Nexus one. You could even test them side by side and see for yourself.
Also, some facts:
- CDMA 3G is LESS power hungry than HSDPA when actually using it. Heck, EV-DO even uses less power than CDMA 2G(1xRTT)! Wi-Fi uses even less, so use it whenever you can.
- There's a huge misconception that AMOLED Screens use a lot less battery than regular LCDs, but in fact, that's only when the screen is showing LOTS of black color. During a web browser session with lots of white webpage viewing, AMOLED has no Power consumption advantage over LCD.
Signal is a HUGE contributor. I get about 12 hours out of my battery 3-4 out of 5 bars. I went to the sand dunes and had 5 bars and my phone lasted 28 hours.

there are some variables here - my router at home sucks, so I actually get better signal (and battery) with 3g and not wifi unless I'm in the same room as the router. Like the guy above me said, signal plays a huge part in it.

When I run Handcent, N1 uses about 20% less battery over ~400 messages. Browsing sees similar results. No exotic apps and I keep close eye of what is running/syncing in the background.

On both phones, I have a % battery gauge. I use both phones in good coverage area and have observed them over weeks of use. I would use one phone for the day, do the exact same thing, use the other phone the next, and consistently see the N1 having 20-30% more battery at the end of the day. I'm thinking of loading "current widget" to see the drain rate between the two phones.
On the subject of radios: I have seen manufatures list longer battery life for EDGE vs. HSPA and the same for 1x over EVDO. Also I [think] usually see longer standby times for a comparable GSM/UTMS phone over CDMA (e.g., Touch Pro2 on GSM/UMTS vs. Touch Pro2 on CDMA).
When one says that EV is less power hungry than 1x, are we talking about a time-use comparison or efficiency? Example: 1Mb download, 1x takes, say, 1 minute, while EV takes 10 seconds. Yes, for that download, EV took less power. But if one were to have 1x & EV both running for one minute, which takes more power? I ask because I remember seeing EV transmitting at higher power than 1x.

Samsung Galaxy S II drains battery too

Hi
If you look at this youtube video it looks like Samsung Galaxy S II also drains batter fast.
Or simply look at this picture and compare battery and time!
I guess they did not think about that when they made the video
This is Stupid. ... How can you conclude it like this. .. !!! Come on man ... Find something proper to post....
Actually looking at the video it seems that the SGS2 charges its own batteries!1
First the battery is at the red level and after that it is back to green level!
dude, it's a prototype, samsung will fix all the bugs before it gets out.
they could use more than one GSII....
What do you guys expect? Battery to last a full week? They made the battery 1650 mAh now.. Screen is bigger, other fancy things.. It's normal that a phone like this will eat battery. It's a half computer!
have you ever been to an expo like MWC?
devices change hands all the time and get max 30mins of charging before they are given to the next journalist...

Has anyone actually seen the back-cover off displaying a 1650mAh Battery.
I'm not saying the SGS2 won't have one but until I see visual proof I'm running with it being a 1500mAh, regardless to what the written spec states.
Batt consumption can´t be worse than on my HD 2. SGS2 has AMOLED screen which consumes less batt power by 25 %.
But since this is really an "ALMIGHTY" phone one will use it for everything during the day, so will batt-drain SUBJECTIVELY be big...........

Well you are comparing 2 different things. Android allows you to run apps in the background which uses battery, it has a touchscreen (most symbian phones don't have that) which is a huge drain.

Did anyone manage to have 40hrs++ battery lifetime?

Dear People,
I am posting this out of big ENVY from my friend's story of his iPh*** 4 battery life with 40hrs ++ of usage (social network on, moderate usage, data always on, bla bla bla) and he still got 20% left of his battery!!!
I was just wondering did anyone managed to experience 40hrs ++ of battery lifetime? My best achievement with my nexus s battery life is
1 day 3 hrs with
MIUI Rom JB 2.8.17
Marmite Kernel 4.3
SmartassV2/deadline
100/1000
Automatic brightness on
Could we EVER achieved 40hrs ++ battery lifetime??? Since Iph*** 4 has practically same specs with Nexus S
It has 1Ghz procs, 512mb ram, 1500mah battery, bla bla bla
Any comments?
A very big advantage of the iphone is the very dim (to my opinion) screen backlight. If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

I've been getting pretty excellent battery life lately, will put up a screen shot but got almost 52hrs battery life with wifi and 3g on until it got to about 15% with about 2h 24m screen on time, although this was pretty light usage to be fair.
Using codename 3.3.2 with standard kernal, I turned NFC off and this seemed to help massively although I've also heard the new Maps app has solved some battery drain so not sure which has contributed the most.

52hrs?????? Cant wait for your screenshots man!
You may think the specs are the same, but the hw in the iPhone and power management is still superior. They get a push notification, even while the 3g radio is in idle and almost off (in which it saves more power). It's hard for Android to optimize the power management specially because of that many hardware variations, it's not only the CPU that counts.

Well, thats good to know, but since its the software differences (meaning coding and stuff), surely (i assume and hope) that we could also applied it (somehow) in our devices through tweaks, can we?
IMHO not much is possible since this is older hardware already and a question for how long will Google bother with it. It might be alot of work needed and you gain some insignificant amount of savings.
Would be nice to see some kind of power management tweaks in coming version of Android though.
well its halfly because android works differently and half way because of the hardware.
yes, the hardware is similar, but the nexus screen takes up more power, the processor is not very efficient, and nfc takes up power... also, the 3g radios are honestly HORRIBLE on the nexus s and that might have something to do with it.
but, the software side does make a major impact. iPhones do not multitask like android, which saves power on slower devices like the iphone 4. thats only half of it though, for instance, the iphone 4S has much worse battery life than the nexus s (by far). ROMs make a big difference also, I am very picky when choosing a ROM- if it doesnt have great battery life then I immediately replace it by another ROM that does.
I get on average about 16-20hours pretty consistantly if you are wondering, and I am OK with that as long as it makes it to the end of the day... I wake at 3:30 and normally it does. My advice is to experiment with different ROMs, I would suggest some, but I use an S 4G...
I don't really believe it. My friend has an iPhone and he uses it quit a bit and seems to have to keep it plugged in as much as I keep my phone. I think he said he usually gets about 8 hrs out of it. And the screen is pretty dull compared to mine so that might make a difference to

The iPhone screen is a lot smaller too and that's a big tradeoff.

So I was just wondering..

How does the best that apple has to offer (4,4s,5 whatever) compare to our Nexus 4 in terms of screen on time. I see 4-5 hours screen on which I read is normal. 2 1/2 hours if playing a big game like The Sims 3. I can't seem to find a straight answer through searching so I was hoping a well versed Android user can tell me how many hours of screen on time that a healthy iDevice achieves on average.
They actually magically have some great battery. That is if their on a bugless ios version. From all the past idevices I've had I get more than average battery. I guess it depends on the user.. As for charging they charge hella quick.

Great question
Ios battery life is better simply because it's much simpler compare to avoid complex os with true multitasking. N4 also has to support a more powerful chip and bigger screen.
Sent from my Nexus 4
Yeah, you really can't compare. N4 has: Bigger screen, more powerful processor, faster gpu... the iPhone has better battery life most likely because it is better optimized and has a far smaller screen.
I really don't care about what you can and can't compare. I would just like to know what real users experience on an iPhone in terms of screen on as I've always been an Android user.
Also the iPhone 5 does have a 4 inch screen, dual core and 1gb ram so I'd expect it to last longer as well as not be a contender with the N4 in performance. Sims 3 on the N4 is unbelievable.
I don't want to have to register on another forum and would just like to hear from a real user.
I don't know about that. I am surrounded by people who use iPhones, and everyone of them think that their battery life is ****. I reckon that at this point every smart phone (apart from the Note II which has a huge battery) just have crappy battery life.

Wow I just did a search on Note II average battery life and am seeing many screen shots with 8 hours! If it weren't for the facts that I don't want to carry a tablet in my pocket everyday and my N4 (and Gnex before it) never once has come close to running out of battery before coming home at night, I may consider the Note 3 or current phablet as my next phone in a few years.
Still would like an answer to my original question, though.
Anyone?
If you check the Anandtech Nexus 4 review (I can't post a link as I'm a new user) it compares the the 4, 4S and 5 to the Nexus 4 in browsing tests. For all devices screen brightness was set to 200 nits however the nexus is stock. In short you'll get about twice as much browsing time out of an iPhone 5 as you will from a stock Nexus 4 on mobile data. On wifi you'll get about 1.6 times. Although it's not a "screen-on" test it's a good gauge of battery life.
http://blog.gsmarena.com/google-nex...test-see-if-its-better-than-the-galaxy-nexus/
The iPhone5 does consistently great in battery benchmarks.
The Web Browsing performance (what matters most IMO) is hands-down incredible.
My guess is that the smaller screen and highly optimized CPU are responsible.

Thinking of getting this tablet-could you post battery stats?

Hi guys.
I'm making a decision between this and the Samsung galaxy tab s 10.5 .
It seems that the battery life on the sony is actually much better than the samsung despite the samsung having a greater capacity. Could somebody please post up some stats from the real world usage of the sony? I'm thinking total screen on time, total battery life, time between charges.
Thanks!

I will not have less than 5% battery till 2 days or so. But I can tell you for now that watching movies, a full charge last 11 hours.
Enviado desde mi SGP512 mediante Tapatalk
Look in the tweak for more battery time thread a few down from this one. I posted mine in detail.
Considering the capacity of the battery, the battery life is outstanding. For example when the tablet is idle it uses virtually no battery, games and movies will see it drop but not at a fast rate, it would defo see you through a day of hard labour. This is why sony stuck with the quad core, and the very beautiful screen. Having looked at the samsung galaxy s with their superior resolution and octa core, Im glad I went with sony, as looking at the threads over on xda people are not happy with battery life, and they are complaining about lag in games, I guess the octa core era has not been totally settled
Hell. 4 cores is more than you need really! Especially in Android. It's not even really used fully in a much more complex os like windows!
BS. 4 cores is saying nothing about the capability of a device.
There are plenty of laggy, slow phones and tablets with 4 cores out there.
I think that the number of cores is less important than the actual day-to-day handling of a device.
I am trying to make a decision between the two best devices here, and the Samsung has double the number of cores. This is irrelvent if software and hardware implementation means a slower actual experience than a device with half the processor cores.
Or indeed a longer-lasting device with a ~30% smaller battery capacity.
I've seen the battery thread mentioned in the reply above- thanks for that.
Can anyone else post their screen-on time or general impressions of battery duration?
Thanks

My point wasn't that because a device has 4 cores it must be good. I have two Rockchip 4 core devices that are not fast! My point was that octa core is complete overkill as even with 4 cores they are barely ever all used.
On an additional note: I know that the point of the Samsung octa cores is that they can run on the lower freq cores for low Intensity processes for improved battery life, but our 2.3ghz cores can also run at a lower speed when more is not needed and although this may be slightly less efficient than the Samsung 1.3ghz cores, I would still choose the Sony any day on cpu alone!
