Holy crap. 5.7% minimum drain an hour while the phone sits? You need to dump the custom ROM and kernel and go back to stock. Because whatever you're doing, you're doing it wrong.

Are you on wifi? Or 3G? How much stuff do you sync? There's plenty of discussion on Nexus 4 boards, and if you use 3G the battery life is night and day difference. There's always people who come on those boards showing 3 days of battery life. So?

I've done tests. At night when exchange doesn't push, drain is at 1.6% / hour. This matches what many users get. Turn off latitude and it drops well below 1%.

During the day, turning off latitude, and it's around 2% per hour.

Basically with Android you have to be VERY careful with battery use. Any app and the battery use grows exponentially. Meanwhile I have all these services syncing on my iPhone and things look great.

I dunno if you can make that a blanket statement for Android in general because it's certainly not that bad with my Note 1 for instance. Active screen-on time for that phone is terribad but I never turn off sync and still get under 1% per hour in standby assuming strong 3G or wifi.

The Maxx is a flagship phone, it doesn't matter what size battery it has. It's for sale and can be obtained and so it belongs in the conversation.

And LOL at the Engadget test. I have a Note 2 and it runs circles around the iPhone 5. I had to use one for a month testing for our company, by the end of the day the iPhone needed charging, which is the typical expectation. The only phones that have ever been able to last me two days with typical usage are the Maxx line and the Note 2. In my case the iPhone was a hair better than the S3.

The Maxx and maybe the Note 2(according to your uncontrolled tests) beats the iPhone in battery life.

So somehow this makes the iPhone 5 the middle of the pack? Wow

Click on expand on each. The iphone 5 only wins in the browsing test. It's nothing special in the other tests. Seeing as I spend more time making phone calls than anything else. A nexus 4 would be a better option battery life wise for me.

A laughable comment right?

Also, 20hrs 3G talk time? Holy crap, I need a new phone.

Believe it or not, most smartphone users use data more than minutes.

Most of my Data goes to app downloads and updates, not browsing. Only time I do browse is when I quickly need to search for something.

Well maybe I just picked the wrong phones like the SGS2, Nexus S. I think Nexus Phones have traditionally sucked for battery.

SGS2 was bad for development so maybe the kernel is filled with hackery that ruined it.

Perhaps the best way for me to make statements is to have an SGS4 or something with a stock TouchWiz ROM?

But then this goes back to my other sentiments about Google doing a horrendous job in optimizing their software and relying on the phone manufacturers to do the rest. Remember when the Droid used to get the best talk time but every other phone would get half of that? Seems we've come a long way. We get great talk times now with the Nexus 4 and HTC One X, etc. But they still suck at browsing.

Most of my Data goes to app downloads and updates, not browsing. Only time I do browse is when I quickly need to search for something.

There's syncing too, but I think in general the iPhone seems to do very well in idle. Why does my Nexus 4 eat battery so badly? I guess part of it is the Qualcomm msm_hsic wakelock issue on the Nexus 4. Or perhaps Touchdown is a horrible exchange app?

But in general Nexus 4 users say there's bad battery life. The Nexus 4 did well in talk time only. Browsing? Fail. Video? Fail. Anandtech Bechmarks? Fail. Engadget? Fail. And honestly I see that in my daily use. Maybe if all I did was call and text (no data), this phone would rock.

What I'm saying is that some sites seem to take the numbers approach (X does better in a specific web browsing test) and then subjectively proclaim that device has the best battery life, even if it's only better in one specific scenario. You can't do that, just like I can't go and say because the Note 2 has better overall battery life than the iPhone 5, it is better in any kind of battery test.

The things I had setup identically on the Note 2 and iPhone 5:

Exchange and Gmail push (combined 50-60 emails a day)
Twitter push
What's App (100-200 messages a day)
Roughly 2 ~300MB Dropbox downloads each day (TV episodes, watch 2 a night)
Maps/Navigation usage, about an hour a day (mostly to check traffic on various routes in the morning and evening)

The Note 2 also had:

Google Talk
Google Now, set to show and alert weather on location, as well as traffic alerts from location in the mornings and evenings.

The Note 2 consistently lasts me two days with this type of usage. The iPhone? one day.

The iPhone 5 gets one more hour of playback in the tests, but who watches 8 hours of video in a day? Same with the Moto phones getting 20+ hours of talk time, no body spends that much time talking on a phone. What we need is a quantifiable mix of all these different uses that would more closely resemble real world usage.

Also the Maxx is the flagship Razr Phone. The flagship is your best. The One X was the flagship until they launched the One X+ or whatever it's called, which then became the flagship. It only makes sense not to include a phone like the Maxx if it had a battery so big the device was comically large and thick like those extended 3rd party batteries. It looks like a typical flagship phone though.

I do agree with you benchmarks don't tell the entire picture. I that's why there's also typical standby benchmarks that need to be done, but that's more difficult. However, I don't think I'm entirely wrong in saying Android in general tends to use more battery power in standby.

iOS uses push strictly, while Android tends to use background processes to sync. Now that Twitter finally has push on Android, in order to get push, you also have to periodically pull. I had some debate here with some folks, and while they told me that they like the pull function, it doesn't take rocket science to figure out that adding pull uses more battery.

If you look at idle numbers for the iPhone 4, 4S, etc, they all idle with less power than the HTC One X and SGS3 (Source: Anandtech). I don't know how they do it, but Apple squeezes more battery life out of their devices.

So maybe the GNote is done well. Who knows? My basis is the Nexus 4, which runs horrendously. But what do you do on an iPhone that kills it in one day? I'd have to play at least an hour of temple run and have all my syncing to bring it to a point where I have to charge at night. I already showed you what I sync on my iPhone. I also forget that I have some 8gb of photos on there. I have Google+ sync on my iPhone, so it's constantly uploading new photos.

I tend to not like to rely on anecdotal data which is why I even view my anecdotal evidence as meh. If the best objective data we have is from benchmarks, then they should be used for discussion. They may not represent true use of the device, but I'd say it's better than nothing.

As for the Maxx, it's the flagship yes, but the Razr HD is marketed as the main phone. The MAXX is just a HD with a bigger battery. That's how it's marketed. It's designed to be a battery monster, so yes I expect it to beat everything. I'm not saying you can't point that out, but having the MAXX beat any phone is a meaningless statement. Also with a MAXX beating an iPhone doesn't make it middle of the pack now.

Middle of the pack is probably what the HTC One X or SGS3 international are scoring in battery tests. The Nexus 4 would score low, and the iPhone 5 would score high. The MAXX would score even higher, but isn't that expected with a 3500mah battery? Also isn't the MAXX a Verizon only phone? It's practically unavailable everywhere else if that's the case. I don't see how that counts as a competitor.

I think Nexus Phones have traditionally sucked for battery.

You know, that does seem to be true. All four nexus phones have had mediocre to bad battery life (even when they shouldn't like in the case of the Nexus 4 since it's the same as the Optimus G which has good battery life).

Yeah. It's disappointing. They shouldn't. Not sure what's going on.

Is this a kernel issue? Does Samsung, HTC, Motorola load some stuff to help their phones sip power more conservatively? I look at a GNex like a SGS2, but the GNex gets stomped on by the SGS2 for battery. We're not even talking about the LTE version.

I find my gnex gets better battery life than my old sgs2. Not that either is great on cdma.

Interestingly enough, the Galaxy Nexus LTE has a larger battery than the GSM one.

In any case, I don't care if it takes kernel tricks or larger batteries, this is something more focus on would be nice especially if they're going to insist on non-replaceable batteries.

I hear rumours that the S4 will have a 2500mah battery which should give it a good battery life.

Because gnex does get better battery life than sgs2. Unless of course you're the guy who's Nexus 4 drains 5.7% an hour on standby.

Sorry - I was referring to phones like the S3 and its competitors (DNA, the new One, the new Xperia) - all which seem to have noticeably worse real-life battery life than an iPhone 5 (the only thing I'm jealous of my wife's phone and I struggled with when I switched to my current S3). Amazing what the 5 does with a 1440mAh battery.

The Note 2 gets around it by having a huge honking battery and I don't have any experience with the Motorola phones (efficiency or huge honking batteries?).
How many total pixels on that tiny 4" screen is the iPhone pushing?

If those pics are real then I'm unimpressed. HTC One wins against this one IMO.

Even though the One is objective superior in many ways it is not even in my radar, because going S4 is a much, much safer bet when it comes to support, modding, and accessories.

Well I wouldn't be too worried either way. Modding is definitely a problem but if it's like the One X+ then it'll be unlockable (even the One X was unlockable unless you're on ATT so that makes it 100% ATT's fault).

Accessories and developers seem to be large (not as large as the S3 but what is?) for the One X as well.


With that said, I picked up a cheaper One X as my temp phone until the Note 3 comes out and 16GB without microSD is STUPIDLY small. You only get 10GB user space and this is the first time since I owned a dumbphone that I reencoded my music so I wouldn't have to be worried about filling my phone.

I work with people that have iphones 4s and 5s and they all tell me they wish there phone would last as long as my gs3 does.I can easily get a day out of it and Im a power user,heck just last night my brother came over and asked if you had the departed and I said give me 5 min and dl it on my gs3 and streamed it to my tv and the cell was at 31% and we watched the whole move and I was using the phone while watching and I just plugged the phone in this morning.

I have everything on push,ruzzle,snapchat,FB,email,google sync and gps on and I can easily get 5 hours of screen time on my gs3 on the stock rom and kernel.

Which ROM are you on? It makes a huge difference on my friend's GS3. He likes the Cyanogenmod nightlies but for a while he was draining a couple percent per hour in standby.

In any case, the iPhone 5's only strong suit is internet browsing. Everything else isn't something write home about.

Im on the stock rom and kernel! ohh and all my music is on the google server and stream about an hour a day at the gym.

I keep the screen at about 25-30% and use wifi as much as possible.From my own testing the modem kills more power then the screen on the gs3

My gym and work have wifi so I take advantage when ever I can

Not if your S4 comes with a Exynos processor.

don't you have a extended battery? people talk about 6hrs SOT on a Nexus 4 all the time with so I'm not sure how 5 hours is that amazing.

and like your own post said, you stay on wifi. I can get amazing times on my Nexus 4 if on Wifi, while I NEVER set my iPhone 5 on Wifi. It's on LTE permanently.

Stock battery my extended pos battery was actually getting worse.there are 2 I phones 5s in our family and I can tell you first hand real world use the gs3 blows it away in battery.

I'm a power user and also have live news and stock widgets on my home screen.I managed 6 hours one time but stay right around 5-5.5 ost.

Basically I get a full day without charging with all push turned on with easy.

Gs3 gets great battery life with latest ota update
