-_- the octacore chip won't affect the battery negatively. It'll increase battery life.
[Galaxy S 4 Q&A, Help & Troubleshooting] hung2900:
People are confusing.

When they talk about CPU strength, they complain "Oh it's not 8 cores, only quad-core. Octo-core is a gimmick"

When they talk about power consumption, they conplain "Why we need 8 cores? They will eat up your battery quickly"

In reality, I saw a same person commented both on a website.

P/s: personally, I prefer HPM implementation. Accourding to the instruction, without any task needed, cores will be shut down and vise versal, all 8 cores can run at the same time. So we can have only one core runs or all 8 cores run, which increases the strength significantly but only affects a little on battery.

I know they are different models but if a S3 i9305 can get this kind of battery life with 4g on over 90% of the time, then I imagine the S4 with a 2600ma battery should be just as good, if not better.

I can't possibly imagine 2600mAh will be a problem. Just plug it in every night and there won't be any trouble at all. If you do think a 5" smartphone should last 14 days on a battery, you might as well spend your money on a time machine.

Since screen takes the majority of the battery, battery : screen ratio is an important stat, and the S4 has 520mAh per inch to the Note II's 564.6, they are not so far apart. Much depends of course on screen technology plus SoC and antennas, but lately Samsung has battery pretty well worked out, see GSM Arena stats for the Nexus 10, Galaxy Premier, Grand, Mini, Express or Note II.

But there is never enough juice, I could've dealt with a bit thicker phone for 3000mAh or more, especially as plastic makes the S4 so light, oh well.

Droid DNA got 5-inch screen but could barely fit a 2000+ mAh battery. I think for the S4 to have a significantly better battery at 2600 mAh AND be slimmer than the DNA (not to mention have a REMOVABLE battery!) is a significant achievement. I'm sure it will have great real-world performance. I just wish they get rid of that white theming on the Settings page/app!!

Battery life?

So what can I expect for a battery life if I don't use any juice defender and spend about 1h/day surfing internet (+ 0-30min of calls)? Any idea, approx.?

I would like to buy this phone but my concerns are battery life and slowing down/lagging of android phones. At this moment I have Galaxy S i9000 but it's so laggy that I hate it. It has always been like this. Only after updating it runs smoothly for a week but then it starts to slow down and become laggy. Is it the problem of all android phones or is it just my phone's problem?

GSM Arena has done their battery test and the S4 seems to have excellent battery life. A rating of 63 compared to 50 for the S3 though not quite as good as the 69 for the Note 2.
[Galaxy S 4 Q&A, Help & Troubleshooting] porkaysi:
this looks very promising, idk if he just got the phone but with proper battery (5-10 battery drain and recharge) break in and not running brightness at 100%, screen time can go easily go over 6 hours out the box. does s health mean bluetooth since the s-band is bluetooth enabled and does that mean extra sensors (humidity and temp) are running?
[Galaxy S 4 Q&A, Help & Troubleshooting] BoneXDA:
That's just epic. It's a 5" FHD screen that is brighter, equipped with a more powerful SoC, more sensors and a slimmer body. Breaking the 60 hour mark for the Snapdragon variant makes us wait for the Octa even more, yet we are now less concerned having the SD600 in our region. Top notch performance and battery - sounds like a winner!
[Galaxy S 4 Q&A, Help & Troubleshooting] Mithrandir007:
HTC Zoe is nice and all, but the S4 has at least as many features for its camera as well (many are the same actually, like Eraser, drama shot, and quite a few that the One doesn't have).

HTC Boom sound... not sure how good that one is compared to the Wolfson chip in the S4, we have to wait for tests to know that one.

HTC Sense 5 - That's completely subjective.. I used to love HTC Sense on my previous phone (HTC HD2 Windows mobile then Android + Windows Phone), but I got a bit bored with it, and the new version adds Blinkfeed which I don't care about.

I now prefer TouchWiz, although I didn't like it in its previous iterations, but it has improved a lot.

It's a 4 MegaPixel camera, Ultrapixel is just a buzzword to say that each pixel is bigger.

Tests (GSMArena) revealed that the HTC One camera is better than all other 5MP camera phones, but a lot worse than newer 13MP camera phones, except for low light pictures.

EDIT : Looks like I was wrong.. the S4 also beats the One for low light pictures (according to GSMArena), which is pretty sad for the One, since it was one of the things that should be better on the One.

Here's actually what GSMArena says about the advantages of each phone (though I don't get the Beats audio part, I've never been impressed by that) :

Samsung Galaxy S4 over HTC One

Bigger screen; works with gloves and air gestures

Higher resolution camera - 13MP vs. 4MP

Newer Android version - 4.2.2 vs. 4.1.2

Multi-window multitasking

Higher clock speed chipset

Expandable storage

User-replaceable battery of higher capacity

Additional sensors (barometer, thermometer, hygroscope)

Exclusive software features

Smaller, thinner, lighter

HTC One over Samsung Galaxy S4

Brilliant-looking aluminum unibody

Optical Image Stabilization, image sensor with 2µm pixel size

Just because the S4 has more features does not mean it will use up the battery quicker. The phone hasn't been released - no one knows how well it will hold up even though it has a 2600mAh battery which isn't a bad battery - it isn't the best battery we've seen however. If the S4 happens to have bad battery life when it debuts then learn to cope with it by tweaking the phone so it uses less battery - although like another mentioned .. you sound set on not getting it.

[Galaxy S 4 Q&A, Help & Troubleshooting] RusherDude:
The new interface for the S4 is both horrible and retarded (horrible since it's like Froyo and it sucks hard, and retarded because it uses a white-based theme on an AMOLED screen.). 99% of the new stuff on the S4 are pure gimmicks and 99% of the people won't only ignore them, but also disable them to get better battery (in one of the reviews, the 4h20m screen one, one of the notes was "battery time increases dramatically when turning off camera gestures").

Also, there's any s1 out there with an octa-core and a 5" full-hd screen? I want one!!!!

The battery of Samsung Galaxy S4 is 500 mAh more powerful than the one of the Galaxy S3, but considering the bigger full HD display, the battery life shouldnot make much difference between S4 and S3.Note 2 owns the biggest battery but at the same time it owns the largest screen,so the battery life should be very similar as S3.

The reason why the s4 gets 66h of endurance compared to the one's 48h is because the s4 is running android 4.2.2 while the one is running android 4.1.2. If you saw the battery performance of the nexus 4 running android 4.2.2, you will notice a similar trend-- android 4.2.2 has REALLY REALLY GOOD standby time Thus the s4 has way better battery endurance compared to the one as shown in the gsarena battery test.

[Galaxy S 4 Q&A, Help & Troubleshooting] Hironimo:
People should stop at judging battery live by just how many mah it packs.

Please also think of how much the sceen needs in comparison.

The surface of the screen grew by about 8 percent, while the size of the battery grew by almost 24%.

At the same time the S4 is smaller and has more features packed into it. That's an achievment.

While the size of the batter does matter one should consider the size of the phone versus the size of the battery and stay realistic.

The original poster expected a battery larger than that of the note 2, but that's a much larger phone.

When you think like that he could have said: the galaxy note 8.0 has a 4600mah, so the s4 should have more than that.

Also in my experience the biggest issue on battery life, specially when it comes how long you can wait until you recharge at

average use - thus standby batery life - is currently the software:

Badly written firmware and apps cause it to go down like crazy because the CPU does not go to sleep enough.

I've seen the first Galaxy Note go about 10 days in standby when you did not use it much.

On the Note II I'm happy when I get 3 days. Huge difference.

There are just too many variables to battery life to be able to judge it just by the size of the battery.

will the dimensions of the S3 extended battery fit into the battery bay of the S4? I can see why the 2600mAh is a deal breaker for some. If I were on Verizon, I'd only buy the Razr Maxx HD. As an ATT customer, I have an S3 because the other smartphones on ATT other than the Note 2, which is WAY too big for a guy my size, have bad battery life. Thankfully the extended battery is available for the S3, and I'd be surprised if there isn't one for the S4. but were the battery non-removable on the S3 or if I had the S4 on that, I'd go and buy an unlocked international Razr Maxx HD.
