I've seen it make a difference tho...I have had android phones where I have had the worst battery life ever until I wiped battery stats.
Same people who tell me ATK will kill your battery yet I always get the best battery life using one and usually better battery life than those claiming they are bad...

You all are aware that a lot of variables affect battery life, no? Correlation does not necessarily equate to causation.
I wiped stats when I replaced the battery on my OG Droid, no idea if it helped the old battery was short cycling.

Yeah, I'm curious if it helps the battery life of the Xperia S by a lot more.

It helps a bit, but think of the fact that your mobile doesn't use that much energy when it's on standby.
You would mostly benefit from it when you are actively using your phone. If you think you could do with a less powerful phone with the tasks you do you could give it a try.
It's difficult to give exact numbers, you could check out the threads in which underclocking is discussed. (it also depends on the kernel)
This thread isnt s2 speicific but i love my s2 and xda has the best minds around so..
My bosses are due for an upgrade and i have been reading everything under the sun about which smartphone has the best battery life... problem is, every website has different results if any on battery life. I realize that big screens and quad-core are all the buzz, but the HTC inspire that one of my bosses has, is a battery hog. We have tried everything to get more life out of the phone, new batteries, multiple batteries and nothing seems to help. The one with the HTC is a power user. Texting and calling around the clock. I would like to get him another HTC with the same screen size because he is used to it. Any ideas/websites would be appreciated. I have read too many reviews and battery life seems to be an afterthought with most reviewers. I like to see test results and comparasions on battery life but so far i have not seen any good ones.
thanks in advance!

I'm sorry but this really doesn't belong here as this is the s2's troubleshooting section, not the "which phone is best" section.

So I just got my HTC one on Sunday night. The first thing I did is let the battery charge up and then drained it to less than 3% and recharged. Ive been getting horrible battery usage since Sunday and am starting to worry that I might have a hw issue. For example, today I woke up at 5:30 and unplugged my phone. Its now 10:15 and I am at less than 30% with less than 30min of screen time (in battery save mode). Should I just go back and replace with my 30 day warranty? Or should I try to calibrate it? I have yet to root it because I just got it, so no custom kernels or roms that might be draining it. The idle and HTC Sense seem to be the programs draining it the worst based on the stock battery usage report.
Give it a few cycles

I really dont understand the "give it a few cycles" or "let it settle in" statements when it comes to battery life. This is software, not some mechanical machine. how does cycles or settling in effect anything? Can someone please explain

I don't know the exact mechanics of it but battery life almost always improves after using it for a little while, that's the way phones work
Sent from my HTC One using Tapatalk 4
Wow, that's a lot. You may want to check apps running in the background. The culprit on mine is the Kernel and there's nothing I can do about it.
I'm actually getting pretty much the same battery life. Prior to the update my average was 13 hrs. 4 hrs screen time. All on stock.
Sent from my HTC One™
I've never heard of the whole settling of the battery with my previous phones. Usually just the whole make sure to drain it all the way the first time and get a full charge, then it would be good. That being said, I could very well be wrong and you may be right, but if it is a hardware issue I would like to return before its too late

I see how this could make sense for a device that is fresh from the factory (no cycles on it)
I'm referring to when someone has had a device for months and flashes a new ROM. people use the "let it settle" justification for when new roms are flashed. I'm just trying to understand what exactly happens during this "settling" period improves battery life over time

i'm not 100% sure but my assumption would be that, new ROMs change your phone entirely. they assign different values to resources, it pretty much changes everything that your battery has grown custom to, so maybe the battery needs to settle in and get used to how resources are now being used.
i also notice reduce battery life. went back to 4.1.2.

It's mainly for the kernel. It has to run thousands of lines of new code, build the caches, add thumbnails, sync all your stuff, etc. It usually doesn't take a few cycles though, just one.

When I updated to 4.3 my battery life was horrible. I would get 3 hours and it was dead. I factory reset and all is well! I've been on battery for 11 hours and have 40% left!

As people have said, you have to let it go through a few cycles before it proforms stably. When I first got mine it was the same situation you describe, couldn't even make it through half a day without charging. Without changing anything (seriously, everything is still stock), that increased to regularly getting 40hrs per charge with about 2hrs screen on time. I could claim that the software is learning or that the hardware handling the battery is improving, but I don't know, I just know that this is a pretty universal phenomenon and it is real. And for me 4.3 had only made it better (not much though, but definitely not worse).
Just give it time, it's about to get good
Also, I can tell you from my tests earlier on that wifi was one of my biggest battery drains, so I just don't use it at all now. But you could just get in the habit of turning it off at certain times or get tasker to handle that). Also power saver is useful, I do notice it slow down but only in the text message app, everything else is still very smooth and fast. And yes, even now the Android system averages 80% of total drain for me. A large portion of that is wakelocks, and there's lots of excellent tutorials on xda about how to find and deal with some of them. Personally I've made my peace with the ones I encounter, so although people tell me losing 5-8%overnight to them is too much, I'm fine with that. Again, much better now than my initial use led me to believe.

Makes sense. Thanks
If it's draining as fast as you say suggestion is charge it up, put it in airplane mode over night. If it still drains, bring it back for a replacement.

I've heard varying reports of how long peoples' batteries last, anywhere from 9 hours to 3 days. But what seems to be the common theme is that if you use your phone pretty frequently, you'll get maybe 10 hrs, but if you use the phone sporadically and not for long periods of time, you can expect the phone to last through the day and even maybe the next. But with mine I've found that the battery on average will last me maybe 10 hours, but that's with slight to almost no use. From what people have said online, the screen is what sucks up battery, but when I check with GSam Battery Monitor, my screen never seems to break 30% of my battery use. Apps are what usually take up ~45% of my battery. What's up with this? I don't wanna have to buy that stupid Mugen case, because it apparently sucks, but there are literally no other options to extend my battery... any advice? Will post screenshots. Thanks!
GSam screenshots
Also, as you can see, the individual app %'s don't add up to the huge number that Apps is taking up... is that related/significant?

It looks normal to me. Usually the people that are saying they get good battery life are the ones that are on a custom Rom and a custom kernel. From my findings the stock Rom especially with the net updates battery life seems to be worse with each update. One really good combination I have run that yields amazing battery life is CM11 and crpalmers kernel. That combination will give amazing battery life. It also depends on what you use your phone for. Judging by your screen shots thing look pretty normal. I would try giving battery guru a go in the market of you want to get some more juice. Let it learn your habits and it will help with you battery life.
You also have to remember as the device ages and you recharge the battery you can't expect it to remain fantastic like the first day you got it. Like anything else they wear down over time and can only go through so many charging cycles.
Or it may just be your battery starting to go bad. Its hard to pin point what may be wrong. It may be as simple as a rogue app. Try some of the suggestions I mentioned above and post back to let us know how your doing. If your not rubbing a custom Rom I recommend switching to one. They are packed with features and the battery life is generally better.
Anyways good luck. Post back if you have any more questions.

100% agree. Especially with the updates leading to worse battery life.
I recently switched to the DNA from an S4. Unlocked and S off'd. Flashed 4.4.2 Rom and immediately noticed how awful battery was in comparison to my Samsung. I actually flashed an older jellybean Rom with Sense 4+ and now I'm experiencing battery life as good as my S4, even though the S4 has a larger battery and newer hardware.

Thanks for the info guys i'll keep that stuff in mind. I've tried several times to S-Off and flash a custom ROM but every time I try, firewater or rumrunner or whatever im using that time always says 'connection failed.' I've been unable to find any fix for why it's failing, so i've kind of given up. Any chance you guys can link to any super simple instructions?
Like I honestly don't understand temproot and those things. thanks!

Am I the only one? I just updated 3 days ago with RUU to the latest build. Before the update a full charge would last me about a day and a half with moderate use. Now with the new update I am lucky to last half a day without it going into Power Saving Mode, then about 2 hours later it will be in Extreme Power Saving Mode. Anyone else getting sh!tty battery life since the update?...

Battery life is incredibly complex and elusive. Asking if other experience the same is all but useless. Reason being, such comparisons are just anecdotal and will often not apply to you. There are simply too many variables, such as how you use your phone, what apps, and often most important is reception in your local area. It could be that the new radio deployed with 1.58 simply does not play well in your area. The intent is to always be "improving" the radio software, but its the minority of cases where it actually gets worse, which can greatly affect battery life.
Also, I've seen a lot of cases where AT&T bloatware runs out of control and kills the battery. You might start by looking into this. There are various apps that allow you to accurately see what apps are using battery (in addition to the Usage in Settings). Lots of folks here seem to like Watchdog Task Manager.

Right I understand that, but what I'm really asking are those who updated to 1.58.502.1 from the older build, did you notice a decrease in battery life... Not trying to compare my battery life to someone elses, I get how that is an impossible answer.

How is asking if anyone is noticing decreased battery life after 1.58 any different from comparing battery life? Its the same thing.
I can guarantee that there are some people that have experienced worse battery life; and some have seen the same or better battery after 1.58 (as this has and will occur for any new OTA/RUU).
Not trying to be argumentative, but my point is whether folks have seen decreased battery life or not is somewhat irrelevant, and isn't going to solve your problem. Better to look into what processes are actually causing the drain, and go from there.
try booting into stock recovery and wiping cache partition...has helped some folks in past
I actually did what dudeluv said and am using ART now. Waaaaay better battery life, actually better than it was previously. Havnt ran into any bugs in it yet either. But we will see as time goes on.
