Earlier this year, I was a huge Android fan. I had a rooted G1 with a different firmware every week. My Dream ended when I realized that the battery was lasting me not more than 5-6 hours, even with very light use. This was after swapping out batteries/phones. Also, for working out, I needed a good music player. Android's default one needed a LOT of improvements.
So, when my friend brought over his iPhone, I decided to give it a try. I bought an iPhone 3GS from craigslist. Jailbroke and Unlocked it. The battery was lasting me more than a day, even after watching more than an hour of TED.com talks, and listening to an hour of music. The ipod functionality was amazing with the volume/music controls in the earphones.
Then, I accidentally updated my phone to the latest firmware... which cannot be unlocked. So I'm back to using my G1.
So, the question still stands.. Is Froyo on Nexus One better in battery performance and iPod functionality of iPhone 3GS. Especially with the upcoming iPhone 4G, we can be sure that Apple will increase the battery life of iPhone (as they've done with all previous updates)?
I get a lot better battery life with Froyo then on my 3GS to be honest. Also, as far as the music functionality goes, why do you think its so bad? If you dislike the interface, then you can download a alternate option from the Market. But for me, as long as it plays the songs, view/edit playlists and browse the music I am good to go.
i got slightly less battery life from my Nexus with 3G turned off compared to my jailbroken 3GS.
normally ended up with about 10% less battery at the end of the day compared to my IPhone and similar usage.
the Nexus was stone stock.
Thanks for the replies...
To answer the question about music interface... I think the ipod interface is much smoother than anything i've seen in Android (please suggest something in case I might've missed it). As I mentioned before, I use the earphone controls A LOT.. and am not sure if Nexus One will offer the same functionality.
Battery life is a huge issue for me. As I said, my usage on iPhone was pretty heavy. Let me lay it out here -- this is with Edge.. Push On.. and Location On.
- 1.5 hrs music
- 1 hr video (Ted talks podcast)
- 1.5 hr phone calls
- 2 hr games
- 3 hr Wifi on
With this kinda usage, my iPhone would have 15-20% battery left by end of the day (midnight usually)...
Does your Nexus One match that or is better?
( I'd love to switch to Nexus, if battery is a non-issue... love the Google integration!)
Battery life is across the board on the N1 for some reason. People will have the same set up and get very different kinds of battery life. I know I've never been happy with the battery life of the phone.
A good music player is ³. Cubed. I like it. I recommend the Nexus One if you get the 2 batteries and external battery charger for 20 bucks deal off of eBay. Maybe life will increase but until then having an arsenal of batteries solves my problem.
Ok, I guess I'm back to 8th grade, basic math. Let's calculate. And because you could have just looked in the specs and done the math yourself, I'm not going to look there, and if I bring the wrong numbers - so be it.
1.5 hr of music is almost nothing. Music is optimized for very low battery usage - 20 hr of listening or so. Let's say, 5% off battery.
Wifi on is nothing. You can keep it on for as long as you like, you actually save battery - it turns off 3G/HSDPA and uses WiFi data.
1.5 hr phone calls out of ~6 hours spec ~= 25% battery off.
1 hr video out of 5 hr spec ~= 20% off.
2 hr games are quite destructive. Both CPU activity and display. Let's say, another 25-30% off.
You're left with approx. 15-20%. Surprised?
Oh wait... It figures, no? Do you think one of those systems is going to be significantly inferior in terms of battery life? You don't think Samsung and Qualcomm know their stuff well enough?
Ah, and the difference is going to show if you use Android power and load it with zillion auto-updating and auto-syncing widgets, that'll chew on your CPU idle time and use up your network power.
[edit] That's exactly the reason for varying battery life between users, as the poster above noted. People use their phone differently, and unlike iPhone, it can perform a lot of things simultaneously, without you even noticing (it's enough that you installed auto-syncing widget and made it sync once in 5 min with a good amount of data, for example) - and it'll cost you battery life. Control what you're running, and you'll get more out of the battery.
I came from an iPhone 3G to the Nexus One and the battery life does seem worse. it's always hard to compare because I do more with my Nexus One. My gut feeling though is even if my usage is similar to what I would have done with my iPhone, the Nexus One just uses more power. Part of that may be the higher res screen. Battery usage almost always shows the display as the biggest user of my battery.
I recently have been having worse than normal battery life. I'm not sure if it's due to upgrading to Froyo or if it is because I turned Latitude on. If it's Latitude, then it's really frustrating that the Battery Usage area doesn't list Latitude as using my battery. Kind of makes that a pointless feature if things just get hidden under names like "Android System".
I also agree with you on the Android music player. I use it, and it's not terrible, but the iPod app on the iPhone is just much easier to quickly get to the music you want to play. Also the Genius features are really well done. Someone suggested Cubed. I found it gives a really good first impression but once you use it you realize it's actually just flashy and it functions awful. As far as I can tell there's no way to quickly find and play a single song with it.
Battery life for 3gs is better than nexus..
For my usage the battery life on Froyo is about twice as good as the battery on 3GS. Granted, I listen to slacker radio while browse websites for about 2 hours a day and the multitasking on android is much more natural than the jailbreak alternative.

I am not altogether sure you aren't just trolling. There isn't any way to give a definitive answer to this question, but I'll give you my experience.
No new N1 user is going to say he gets good battery life. You won't want to shut the screen off for the first week.
Now, I can get a day and a half out of my battery on a stock rom if I don't sync absolutely everything frequently, I use wifi when it's available, keeping radios I am not using off and basically, being mindful of power use. I use it frequently, but not constantly. And if I am away from a charger, I have an inexpensive spare battery that I can change all by myself without any special tools all the while sending SJ a FU via ESP.

Lemme get first thing straight.. I have NO intentions of trolling No harm intended. When I bought the iPhone, EVERYONE I know was immensely surprised. I was (and still am) a spokesperson for Android. I love the apps. Maybe thats a reason that we all install so many widgets/apps which use data.... So many are available for free!! and awesome ones too.. for example.. I'd kill for the News and Weather app to be in iPhone.. but its not...
As I said in the original post.. a big chunk of my criteria is battery life.. second big chunk is music... I guess I'm sad that no Android phone yet can beat the battery life that an average iPhone user gets... I was hoping by releasing Froyo, google would change that (hence this thread)...
Trust me guys.. I live by my gmail.. would rather have everything centered around it... than having apple control my life... just dont wanna carry around extra batteries.. like i had to for my g1...
Intersectraven kernels with any nexus one Rom gives me the best battery. Rite now I'm on froyo and have lasted more than 20 hours with the kernel.

Now that I'm using my nexus normally, I'm getting good battery life. 12 hours of solid usage.

Which of Raven's kernel are you using?
I have a iPhone 2G and it beats my N1 on battery but not considerably.. I read that the 2G is teh king while 3G is the worse of the three iPhones. 3GS is slight better than 3G.

Something that people keep mentioning but seems to keep getting overlooked when people compare any device running Android to the Almighty iPhone...
Multitasking. Takes. More. Power.
Being able to run 5 or so apps in the background (along with all the automated syncing that's happening on the network-data side of things) is going to drain the battery more than doing one thing at a time on Apple's product.
When your iPhone is able to effectively multitask, come back and then you can compare the battery life.
Quite simply, Android lets you do more than you could ever possibly do on the iPhone platform. It gives you the option (free will - unheard of on the Apple side of things!) to run a handful of apps simultaneously. This, naturally, uses more power as the processor is doing more. This is not rocket science, people. You choose to do more, so accept the power penalty. Or, you can be mindful of your battery usage and manage things appropriately to get a significant battery life improvement. It's your choice!
And if you still don't get enough battery life out of this more powerful, more capable device, as attn1 pointed out, there is absolutely nothing to stop you from getting an inexpensive spare battery that can be swapped into the phone in under a minute (INCLUDING the time it takes to shut down and power back up).
Trying to compare any recent Android device to Apple's iPhone is like comparing my gaming notebook to my old TI-84 graphing calculator - which did get much better battery life than my current Asus G72 notebook.

Some backstory.
Paul's Froyo.
Tweaked Kernel.
Home++
Sync off
Widgets: Facebook (no notification), ³ medium, Google Search, Power Control, News and Weather (12 hour refresh)
Screen set to auto brightness
Went to bed with 98% charge at 11:30pm.
Alarm goes off at 5am. 93%
Check Facebook. Turn on sync. Browse xda on default browser. 89%
Get on the metro.
Browse the internet.
Read a few news articles in the news widget.
Listen to music with Bluetooth headphones for 20 minutes or so.
Browse xda some more.
Download the latest 925 cfs kernel from ir's thread.
By 7:14 I'm at 64% charge.
In 2 hours doing what I noted here I lose close to half my battery?! That's laughabad.
It's amazing how all over the place the returns are.
I have owned the following phones in the last three years :
iPhone 2G
iPhone 3G
BlackBerry Bold
iPhone 3GS* (borrowed for 2 weeks to see if I wanted to go back...)
Milestone
Nexus One
I, personally, got the best battery life out of the iPhone 2G - I got three days out of it, consistently. BUT, I did not have an unlimited data plan, I did not use it for mail, I always got apps from the store over WiFi, I never streamed music, video or anything else. I had no RSS reader. I listened to some music, played the OCCASIONAL game, sent some texts and made a few calls.
Next would be the Bold. I POUNDED that thing and ALWAYS got at least 2 days out of it. I would send dozens of SMS, read and reply to at least 40 emails/day, use GTalk with my wife for at least 50 messages a day. I'd read RSS feeds with Viigo.
After that, every single phone on the list requires charging every single day.
On the iPhone 3G, I would do a little surfing, maybe a little video, some emails and some text. Music on the metro coming and going to/from work. Charging every day was mandatory.
On the 3GS, with how App Store had better and better stuff, I killed it (as in forced shut down) 5 out of 15 days - all that with no widgets and no multitasking. I would read Le Monde, do some browsing, read tweets, read emails, make a couple of calls and texts. I started stocking the charge cable at work and in my backpack during my weeks with a 3GS, because it wouldn't make it through a day. Most friends and colleagues who have them do the same.
I received the Milestone in December. I loved it, and really started pounding a phone - 100 GTalks a day, some SMS, all email, NewsRob for RSS, Le Monde, News & Weather widget one we hacked that on there (following the Jan 5 release of the N1), twitter and facebook, browsing. App downloads, widgets left and right, plus CONSTANT dev work, image building, flashing, testing, etc. I would get a day if I took my foot off the gas, but if I pushed it too hard, I would kill it. There were a couple of battery killers that were avoidable but which I didn't avoid from time to time - leaving Qik, the browser on the google homepage (with autolocation on) the Camera or Maps open, then letting the phone go "idle" with the screen asleep keeps the GPS on and would eat the battery in an hour or two. This left me high and dry a couple of times, until I paid a bit more attention. The Milestone got better 3G than any iPhone and worse / less-consistent WiFi.
I picked up a Nexus at the beginning of March. It gets somewhat-to-significantly better battery life than the Milestone. I still have to charge it daily, but there seem to be fewer battery-death bonehead choices that drink the go-go juice and leave you without your electronic BFF. Most of that is probably Android 2.1 and the UV kernels - I noticed that the Milestone was better with 2.1 as well. It also gets 10dbm worse radio reception with the same SIM on the same desk on the same network in the same office. But it gets MUCH better and more reliable WiFi, and that is better still since FroYo. I use it a ton - RSS, chat, SMS, calls, LOTS of browsing, Le Monde, NYTimes in Newspapers Full, lots of games in spare time, Google Listen for Podcasts, Music, Movies, taking pictures and videos and posting them online with Twitter, Facebook, YouTube or Buzz, etc.
The Nexus has one MASSIVE problem, as far as bettery goes - charging it on any computer USB port, and many thrid-party USB charge plugs (AC or DC) is atrocious - hours and hours to get just a few percent. I don't know why - Apple can use 1A from anything, RIM / BlackBerry can come close to 2A. My Milestone would take at least 1A from anything. But the stupid HTC kit won't take more than about 400mA from a computer or a non-shorted USB charger. SOME 3rd party stuff will be exploited up until 1A, as will the charger that the N1 comes with, but if not, you're going to see slooooooow charging.
As far as the music player: I want 2 things - good sound and the ability to pause and skip with the mic button. Every iPhone does this, and so does the N1. The N1 DOES support headset buttons (it's own set comes with them), but I use my Shures with a simple mic adaptor. I almost never see the interface - I put on a playlist and shuffle it. DoubleTwist makes sure that I have the same lists on my iPod touch and my Nexus, so I really don't notice the difference.
If you use the interface a lot, well, then the player on an iPhone is the best there is. I just don't use the interface often enough to make that a selling point.
As far as sound - the Milestone got SIGNIFICANTLY more volume and better sound then any iPhone and a ridiculous amount more than an N1.
Froyo just rocks. I miss a couple of CM features, but there are sooooo many good things baked into Froyo - tethering, copy/paste in received GMail messages, SD card app storage, cloud-stored settings, Flash, incredible performance.
Your Mileage May Vary.

Thanks for the VERY detailed post... And also for clarifying the controls thing... thats awesome that N1 uses the mic button for controls... I use it a lot while running to skip songs...
I'm on the brink with my G1 though... Flashed the latest 2.1 ROM from Cygo.. at first I thought it was fast.. but now its driving me crazy.. its not really the ROM but the phone itself.. will post a video of the experience soon..
So to summarize above posts...
- N1 can give same or better battery life than iPhone... provided.. that we use it well... no crazy widgets/apps which keep using data...
- The earphones button CAN be used in N1 to skip songs.. which is awesome for me...
I think I might order my N1 today itself.. as it's still being sold on google (surprisingly enough).. Who knows once only T-Mobile sells it, if they'll stop offering the unlocked option....
Thanks for all the input guys
My girlfriends Evo battery life is horrible. She mainly just text a lot and surfs facebook. I need a rom to get her battery life to where she can make it at lease 8 hours before having to charge her phone.

A 3500 battery...nuff said
Savage-Mod
I would get Savage mod 1.1 with savaged zen 1.1.0 cfs havs sbc. I've been using it for the past week and it has been great. The texting and phone it self is faster and smoother than any rom i've used and i've been through most. I am currently on 65%, its been unplugged for 8 and a half hours. I understand that others may have better battery live but i'm using my stock battery, which is great cause I saved money and didn't add any thickness. PM if you have any questions.
I'm on Myn's Warm Z with Netarchy 4.3.2 cfs, sbc, havs more. Even with heavy usage (including video streaming and web surfing) my battery lasts a good 10 hours. I can't recommend this combo enough. I had horrible battery life with the stock kernel on Warm Z. Only thing is, depending on her hardward build, you may have to test a couple different kernels.
Easy answer:
EViO 2, SetCPU to underclock to 921, remove sense and use ADW.
Long answer:
To really figure it out, you'll have to try a bunch of diff ROM/Kernel combos for a couple days each.
I would try with CM7, the ROM from "yet another AOSP ginger ROM," Salvage-Mod, Savaged-Zen(Mod) RC2, Miui and whatever sense ROMs you want.
Also, Juice Defender and Autostarts will help you.
I recommend CM7 with a Savaged-Zen ROM CFS- SBC. Even after flashing a new nightly, I avg. 13-14 hours the first day before the kernel is broken in. Best of all Roms that I've tried and I really use my phone (data & mp3). Forgot to mention, I use Setcpu with profiles.

Let's face it: women have a better sense of style than us dudes, and no chick in their right mind would put up with having a hideous cinderblock of a phone. 6mm might as well be an inch when it comes to stuffing a phone into her jeans. In the interest of keeping our women looking fine as hell, let's find software solutions to battery life
To the OP, try this first: go into settings/wireless and networks and uncheck enable always on mobile data. When I was on a stock Evo, this helped me immensely with battery life. Also, uninstall any task killers she has. Check what programs are syncing with the internet too, it's really just data use that eats up battery life with these phones.
Also, post up a screenshot of her battery use screen, maybe we can help figure out what the drain is Even a stock evo running the latest Sprint update should get around 10 hours, minimum, with moderate use like facebook and texting.

so you base your decision off the fact that your wife/girlfriend/friend will be holding your phone and will buldge out of her pocket...maybe YOU should be holding YOUR phone, but hey i guess im weird, my girl might hold my phone, but she doesnt stuff it in her pocket and walk around with it thats stupid, besides my girl puts everything in her pocketbook as most do, keeps the figure , at least thats what i tell her lol
I am running well with deck's rom (the "yet another gingerbread" rom), rc9 now, and the new savaged-zen kernel (1.1). The phone is running really well. I just tried the undervolting script and that made a few reboots, which never happened since I went aosp last month, so I removed that. battery life seems really good though. 1st run through on the latest kernel went from about 11pm last night until 6pm today with pretty good use. I expect as it settles in it should do well.
Juice defender should help immensely if all she does is text and fb

CM7 RC4 with Savage Zen 1.1.0 kernel, Seidio 3500mAh battery will give you DAYS of battery life if you use it moderately to little usage. With a stock battery you will still get over a day easily.
I have wifi on most of the day, live wallpaper (the smoke one), I DONT use any task killer (because it actually slows down my phone), Bluetooth is on and connected to my car whenever Im driving (at least 60 miles per day)
I believe that if I have to use airplane mode, turn off GPS, not use wifi, not use the phone to its full potential then I rather have a cheaper phone and get a laptop...
The screen shots below were made with STOCK battery because I wanted to know the real difference in battery life between the roms!
Note the usage... I listen to music, voice calls...
here is another comparisson...
I really hope this helps you find what you are looking for
Actually, lies, those screen shots were made with gginggerbread 6(which is based on CM7) with savage zen 0.2.something...
The following screen shots were made with the specs I mentioned in the previous post... Its possible that the battery has improved note the 10 hours of usage and only 12% spent and bluetooth usage
So my wife hates the battery life of her Inc. I even got her a bigger battery (the one that is bigger but still fits with the stock back) and its really gotten bad. She gets maybe a days use. And use for her is hardly any data mostly talking on the phone. Its maybe 30mins to an hour on average of talking, some texting, and that its about it. I would think the battery would last longer.
I am no stranger to rooting and loading Roms, did it on my Droid 1 and now on my Thunderbolt, but the wife's phone has been off limits. But now its getting to the point where I want to step in and improve it. So I don't want to be flashing roms all the time, just need a stable rom with some nice bells and whistles, a good kernel for battery life, and I can load it and not have to worry about it.
ruby rom 2.0.2 and incredikernel 4/19 and then underclock it in gem settings. the best battery life ive seen ever across any android device ive had. its an aosp rom meaning no sense widgets, but that can be fixed with a third party launcher like Launcher pro plus. Not even sure if thats a factor. You could also try the xda superpower app wgich gives you automation with certain battery drainers, ie. 3g. let me know if you need help, because I have been on the quest for long battery life for a while and this is it.
I think she likes the Sense stuff, don't want to make it look too different than what she has now.
skyraider 4.1 with stock kernel then.
When you say "stock kernel" do you mean the kernel that comes with skyraider or the actual stock kernel (or does skyraider come with the stock kernel?).
it comes with the stock kernel. also check what is syncing and how often in system settings.
yeah I have clean out her syncing stuff, Cell Standby is using the most power, so I am not sure what is going on.
something is syncing definitely too much. my standby time is around 3% all the time and I manually sync.
I'm running SR4.1 with chad's 12/23; I unplug at around 7:30, and by the end of the day (around 10pm or so) I'm usually sitting at around 50-75% battery; that's with wifi/data off (turned on when I need them) and moderate texting (phone on vibrate) all day.
If you're getting Cell Standby as the biggest battery drain, that means she's in areas with low signal and its trying to find a stronger signal.
^^^^ That too. Forgot that part, but for whatever reason ive noticed sense roms have higher usage. Coincidense, maybe.
Do you mean higher usage as in Cell Standby or just in general? Just in general I can see why, because it has to draw more graphics on the screen for the UI.

im talking cell standby. strange, I know.
Hmm, that's weird. Could be because of stuff like HTC Check-in services, since that stuff would be in Sense ROMs...but idk. Guess all I've really used were Sense ROMs, so I don't have much of a basis to judge from.
Cell Standby is when you have no service. That is when it's constantly looking for a signal and can't find it. That's why her battery life sucks. In low service areas, when the service goes out, it starts searching for a signal, which eats battery life. I have the same problem at my job, because there's like no service there. Can try putting it in airplane mode in those areas (which makes it use almost 0 battery), or get JuiceDefender (works great OOTB) and use that to only allow sync's every X minutes......

Not necessarily no service, but low service as well. I live in an area with low signal in places, and work in metal buildings that really cut my signal down as well.
Well we work is roughly the same area (maybe half a mile apart) and I never have that much usage on Cell Standby. Something is screwy and I am hoping a new Rom and kernel that does some unclocking might help. Maybe starting fresh I can configure it better.
She took it off the charger this morning at 100%. When she gets home I will post her battery level and usage info.
1/2 a mile can be a big deal. I don't know the kind of environment / area you're in, so I can only guess.
You could also try flashing a different radio if you want, too. Heard good luck about that sometimes.
Magnolia ROM. Rock steady; NO issues at all.
Tried and true
It doesn't seem to be getting any more updates but Incredibly Re-Engineered was my go to for speed, stability, and battery life.
re-engineered is a good choice as well.
I bought a SG2 some time ago and loved it except for the idle battery drain. For the life of me, I couldn't seem to get it to stop chewing battery when it wasn't being used. I even tested it by charging it to full and leaving it overnight. It lost about 20%.
Remembering that the iPhone 4 had excellent idle battery life, I decided to give it another go just for the hell of it. I hate iOS as a daily driver, but I figured at least I wouldn't have to worry about battery life.
These are my observations:
1) Idle time on iPhone 4 is indeed better. When it's not being used, it uses no battery. However, when being used heavily, the SG2 actually seems to get BETTER battery life than iPhone 4 when it is being used heavily. Not sure why.
2) I severely miss being able to send/upload high quality videos and pictures. I hate the restrictions that Apple places on file size. I don't always have wifi readily available and at least with Android, you can upload large videos to Youtube over the cell connection.
3) I miss the integration in the photo album with social services. It's annoying having to launch an app every time I want to upload a picture/video.
4) The camera on the SG2 is definitely better. You get more fine detail on objects that are further away, no doubt due to the higher megapixel count.
5) I think most apps on iOS look better and are more functional, but the problem is, you have to launch an app to do anything in iOS.
I really wish Samsung (and maybe Google in general) could solve the idle battery drain. Losing 20% over 8 hours without even using the phone seems rather high when you factor in that you'll be losing that battery life whether you use the phone or not. Theoretically, this should mean that the iPhone would get better battery life with the same use, but I'm not finding that to be the case so far. I will probably be going back to my SG2 very soon.
Sorry for the long-winded post. Just wanted to collect my thoughts and present my personal findings.
U r right about battery consumption .
But i m sure Android is going to be so much improved and vast in features that we cant compare to any os in the world in future.
Biggest plus of Android is community like this and the freedom to change things inside it.
agree on most of the things u said there
but
when it comes to battery life i have no idea why its soo random with some people
i lose about 1% an hour on KE2
(stock was on the phone when i bought it no root )
but since i installed KF3
i lose about 2% an hour
rooted flashed from odin
I must have responded to 10+ questions on this forum in the last 24 hours as regards battery drain, i get 25+ hours on my GS2, if you search on here you will find many tips that will substantially increase your battery life.
check the new kernel ninephetamine. Have used the modified 1.4v (with deep sleep enabled).....promising results with undervolting.
Currently OC 1400, and undervolted.
Simple Answer
Iphone does not loose batter on idle cause it puts all apps to sleep state if not used for a while
Android phones in general are always using data for like your emails, facebook, etc if you have set the apps to connect say every hour or so
IF you leave WIFI on it takes up battery as well
I am quiet happy with my SGS2 ( 12 -15 hours ) heavy usage and I am used to daily charging. and its just the day time hours unlike people who may be posting their night time hours as well which add anything form 8-16 more

I'm not interested in disabling everything that makes Android what it is. If I have to modify it to the point that it's an iPhone, I might as well use an iPhone. I'm well aware of battery saving tips for Android. They almost always involve shutting down all automated services and anything that retrieves data. This is not a solution. I have some e-mail accounts on periodic pull and the most important ones on push. On the iPhone, I have all e-mail accounts on Push.
I also don't particularly want to use a custom ROM. I prefer to stay stock.
I'm not getting horrible battery life on my SG2. In fact, I get around 15 hours with the same kind of use as that on the iPhone 4. I would just like to be able to set the phone down for several hours and not lose a quarter of the battery.
i have tried every single battery optimisation and calibration tricks on my Android phones. My first Android phone was a htc hero, second SE X10 and Now Galaxy S2.
All the optimisation and stuff works if you sacrifice something on your phone. i like my display to be sharp and easy to see. I want my email notification to be prompt and so many other things.
I used to be Windows mobile user my last handset was Toshiba TG01. i never ever had any battery issue.
It is to do with Android system, it needs to improve. it has all the pace now and so many chances.
if this roumor is true then IOS will shrink sooner than 2015:

Why my Lamborghini needs more fuel than my Fiat Panda? I can't understand. Crappy Lamborghini, back on Panda.
Well if riding the Panda can get me through the jungle instead of half of it, why not?
Also, the Panda can get me more food via the App Store.
Granted though the Lamborghini has alot more fancy features and doesnt have mindless sheep following it
Anyway, coming from an SGS1, then an iPhone4, I heartily agree with the OP. Android is awesome but it's still rough around the edges. Sometimes the ease and boring simplicity of IOS is something that I miss, along with the Apps and definitely the games which Android is sorely lacking.
But then again I'd be reminded of steve and his itunes bloatware. ugh
Yes, but when Lamborghini is parked it should use the same as the Panda! (I.e. zero.)
Google really should minimise the stuff going on when the phone is idle. Google also needs to do something about all these rouge apps that always start up services that always run in the background. They should provide some way of limiting/stopping the CPU usage of apps running in the background.
Even the official XDA forum app still servers up adverts in the background eating up your battery (and bandwidth) if you press home instead of backup to exit.
wifi sharing is a bit of a bug that drains battery like crazy. If your not rooted thats definitely the screen off battery drain for sure. If there was a reason to root, just root to freeze that one rogue app.

Nope, the wifi sharing bug has now been fixed by Samsung in the stock KF3 release available via Kies.

But most of the stuff is pretty useless anyway all this Samsung bloatware is guaranteed to drain your battery, i don't see it as sacrifcying anything, ive got email on push and i still get over 25+ hours battery,i used an iPhone 4 for a few weeks and id be lucky to get 16 hours with medium to heavy usage.
My data is always enabled too, you can save a lot of battery if you use apps like Juice defender plus and system panel will also tell you which apps,etc are using up more than others.
At the end of the day smartphones are always going to use up much more battery than normal phones and this isn't going to change anytime soon until such time a revoultionary new battery is designed that lasts for days on end.
Until then people have to deal with it,follow the tips and you'll get good battery life, if you want absolutely everything "on at the same time" your simply not going to get it, not on the iPhone 4 or any phone.

Has not been properly addressed. Thats why its not even included in 90% of the custom roms.
Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help
Eclair
Just Eclair
Any Eclair

But seriously, disabling 3g on ICS saves a ton of battery life.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.

3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.
