Just to give some quick history: I'm a power user, but I'm not a programmer, so my knowledge is limited to what I've experienced and not what the XDA community experts would be capable of doing. I've used RIM, Apple, Android, Win Phone, OSX, DOS, Windows from the beginning, and currently Win8 on my PC's.
Android is an excellent platform, but it has one major flaw: Why does it need to use battery when it's supposed to be sleeping?
I could never go back to Apple. It's far too locked down. It's just.. ugly and clumsy. I loved my BB Bold as a phone, and was saddened to see them go the way of the dodo. I use a Windows phone now, because the battery life is well maintained due to it being somewhat locked down, but not to the point of Apple.
Here's what I'm suggesting for Android. This is primarily for tablet users, but could apply to consumer phones as well.
1. There needs to be a way to force a true sleep mode. This should lock down apps, widgets, and all non-essentials. There is no reason you should have to turn a tablet off every time, or check wakelocks, to minimize battery use, if you put it into sleep mode. If it could boot in the time my ultrabook running Win8 does, I wouldn't care. I'd just shut it down fully, and turn it on for a boot in under 8 seconds. They cannot. Neither can the competition. There needs to be a true sleep mode, and a semi-sleep mode, and a completely on state. One should be for, well, when you're asleep or don't care about updates. One should be for background updates working, but not taxing the battery heavily. One should be for full on status and doing all of the great things Android is capable of.
2. Tasker is pretty neat for some things. JuiceDefender is pretty neat for some things. Unfortunately, they don't solve issue #1. There needs to be an app (root required I'm sure), that truly takes over the combination and applies a full lock-down of all apps and data with the press of a button.
3. It would be nice to have a method to do these things for the average person. The Kindle Fire is pretty locked down, but still Android based. It also gets good battery life because it doesn't have as much running in the background when it's not being used. There is no reason why there shouldn't be a way to switch all Android devices to a mode like that, on the fly. Basically, if you want a widget heavy homepage, but don't need them doing anything when you click a sleep button (like on a laptop), why not have it do exactly that. This way new people can have all of the fancy widgets they want, but also not have to power down when the tablet or phone is not being used for anything but phone/text/email-sync use.
4. People won't want this to be something where screen off means no data, or updates. People will want this to be integrated into a quick button push that is easily seen as having been toggled. "Why you no go sleep like laptop?". There is no reason that my Nexus 7 should use more battery power in its "sleep" state, than my Lenovo i7 tablet ultrabook running Windows 8 does, while sleeping. One could last a few days, one could go for a month.
/end rant... I love my Nexus 7, and loved my Droid X, but my Win phone gets amazing battery life when I'm not using it, because it basically does exactly what I've explained (for better or worse). Ipads are similar. The Blackberry Bold was also similar for me (essentially locked down to phone/email when not in use). The Kindle Fire essentially does this to some extent. The iphone... well, that just stunk all around, so that was the only device I really did not like at all (bad battery life, and locked down anyways). Don't get me wrong, the Nexus 7 has great battery life when in use, and after tinkering, but why the need to shut it completely off at night when it should only use about 1% of the battery in a sleep mode during that time, and not 15%?
I have a rooted Kindle Fire running the latest power saving kernal update for CM10 and it can sleep all night with only a 1% decrease in battery life. I understand the point your trying to get across. Maybe in time we'll see some software development that will do exactly what you were saying. Shutting down the device completely is very effective in conserving battery life (especially if you are running many apps and services simultaneously) but also helps the system to run smoothly.

because you installed every kind of apps and widgets that need to run in background, like whatsap, weather widget, mail widget, calendar widget and so on.
modern smartphones never sleep because we want them to be always connected.

There will be lots of wireless power options so you will simply put your phone or tablet for the night and take it back fully charged in the morning..
To my experience the most power consuming part is the bright nice display that eats most of the battery. Waiting for better display technologis.
Thinking a out Windows phone as well.. good idea?

It would be a practical option for tablets, where a sleep function like laptop computers use could be implemented. But even in sleep mode laptops still use power keeping data in the RAM and monitoring input devices for user input. I'm not sure how much power you would save on an Android tablet with an actual sleep mode. The moving parts in a laptop (HDD, fans) shut off during sleep so its power savings are more significant that a completely solid state tablet. IIRC even my laptop uses more than a percent of battery life if I let it sleep on battery overnight and it has a much higher capacity battery than any tablet.
On phones you need the device to be awake to receive texts, calls, etc. Since its constantly connected to a cellular network there is going to power used keeping the connection established. My Droid 3 actually has a sleep mode which is essentially airplane mode plus sleep, I've never tested how well it does with the battery as its my primary phone for now.

I'm just wondering if anyone here is getting the super amazing battery life that I'm also seeing. I'm running Virusrom (basically just themed stock rom with no bloat) had my data connections off, and screen off clock speed set to 200MHz (using overclock widget to control speed)
I got through 12 hours on 3% battery. Is anyone else seeing this?
what overclock widget you using? Just curious...

I would love that...
If I never touch the phone I get this
But unfortunately I can't leave it alone xD

seems alittle fishy since the processor cannot go below 245Mhz.
plus what do you mean by data connections off? No LTE or 3G?
Or do you mean you disabled always-on mobile data? I myself usually drop 10% in about 7-8 hours with that enabled and normal use, with SetCPU telling the processor to run at 245Mhz when the screen is off.
Yea, 245mhz, I didn't have my phone on me, and couldn't exactly remember. No data means no wifi, 3G, 4G. It just could receive/send calls and texts. As for the overclock widget, it's just called "Overclock Widget" in the market.
I am on a stock Tbolt and have disabled the lock screen and GPS when not needed and am getting at least 12 hrs with life to spare. MUCH better then my first day of use
1 1/2 more hours I will reach 12 hours. All I did was to follow this man's tips. I still have 30% left. I'm sure it's nothing new to some of you but new to me as I never had to do this w my old Samsung or Nokia phones.
http://www.phonesreview.co.uk/2011/...tery-cover-should-be-free/#IDComment136566791
I have
1. MS Exchange sync every 15 min
2. Gmail sync
3. Facebook sync
3. SipDroid calls for about 2 hours
4. Pandora streaming for 1/2 hour
5. Surf net about 1 hour
6. Xda app about 1/2 hour
I'm happy and i'm still stock TB!!!
Unless I'm actively using data, I always have it off. Well unless it's on charge haha. As for sync, I don't even sync email (gmail), or anything. I don't really count contacts or apps as syncing as it's almost a one time thing. Most people tell my i Baby my smartphone, but I'm the only one I knew that could get 3 days on my Dinc 3 days no charge on stock battery haha.
Uhh... congratulations?! You made your device entirely useless and got trough 12 hours on 3% of the battery.
What is the point of using your Android smartphone without data all day? Is this a pissing contest to see who can disable all of the core functionality of the phone and see how long the battery lasts?
I turned my phone off the other day and when I turned it back on I used .5% of the battery... woah!! That is absurd battery life for such an awesome smart phone.
Sorry for all the BS... but honestly, why go through all of these lengths to prolong battery life longer than 12-18 hours. It renders the device useless and it no longer provides service to the user. I completely agree with optimizing the device (running custom kernels when they become available), using SetCPU profiles, etc... to a certain extent. If those optimizations impede on performance or functionality in any way then they are not worth it to me.
So ultimately, why sacrifice performance and functionality for the sake of ridiculous battery life. As long as you can make it through the day, then no worries. I charge my device every night anyhow.
I've started using this widget as well, I'll find out its effectiveness in a day or two once I leave it off for a while (like overnight). Only complaint I have though - every time I turn the screen on, it says it's been granted su permissions, right above my dock. Is there any way to turn that off? It's just kinda weird too, if I go to show off the phone it looks bad.
Edit: I do have data usage in the background though.
Well honestly, I am around a computer most of the day, sleeping, or at work (can't be on my phone) I was sleeping most of that 3% loss. When I'm near a computer I tether so that charges without me thinking about it, and in my car I have it on charge because of the battery rape of GPS and 3g/4g. It's still a fully functional phone with no data... I can text and talk all I want. And it's not like I don't toggle on my data when I need it. I just don't see the point of being THAT connected to technology ALL off the item, and I'm a programmer, and an I.T. gupy >_>

In the Superuser app you can change that notification. Also, there is a preference for the notification letting you know the clock changed in the widget's prefs. I turn them off. I normally use a smartass kernel as it works with much less power, but this is better than not having it for now IMHO.

I'll tell you why.
1. 4g tether that rivals my cable internet, and I can have both at the same time
2. I always have data and GPS, which is amazing in my car or anywhere.
3. Why no I have to be strung to the internet 24/7 and not just when I want to? It's always there, at the toggle of a button. I'd rather not be lazy and toggle data versus looking for a charger every few hours >_>

Thanks, I somehow missed that setting when I was setting it up earlier.
Also, I kind of agree with what's said due to the fact that 75%+ of the time I'm awake I'm at a computer. I don't need to have my phone do much more than texts/calls during that time. Why waste battery for that? But when I'm not at a computer, I need it, and that's why I have this phone.

Not a problem. We all miss something at times
As for "needing" data, I personally find myself "wanting" it. I don't have anything that I can't let go of on the internet while I'm at work (can't use my phone for anything but texting once in a while). I always enjoy my data, and use a considerable amount of data, but it's either tethered or plugged in as I'm driving, and may as well. I guess being a minimalist is against the law now a days
i get great battery life stock not rooted but when i added adw launcher and gingerbread theme with ginger bread keyboard i went 1hr and it was a 60% and i never touched it so stock my battery is awesome

I think you've missed the point. Noone will last even more than 6 hours if you don't do the trickle charges or whatever you call it. That's the point. I know you reply to OP but just want to point it out. After charging it the right way, you will certainly last 8 hours at least which then bring to your point "I charge the phone every night anhow".

in settings, there is a setting to turn off data and wifi after a certain epriod of time when the screen is off, saves battery very well.
Ok I have been reading since literally the first day the G2x came out about the "Horrible" battery life of the phone. So, after toying with it for about 8 days I have nailed it down so that the phone gets about 20 hours of Moderate use(Constant texting, internet for emails, YouTube, and searches, and probably about 2 hours of light gaming(not Nova or NFS)). So, Outside of the obvious like make sure your bluetooth, wifi, and GPS are off and turn your display brightness down here are my steps to Better Battery Life.
First - Root The Phone. There is plenty of links and help if you don't know how or have questions about rooting.
Second -(Root Needed) Use Titanium Backup or Antek App Manager(Antek is free) and Freeze or uninstall all the bloatware that you don't use off of your phone. Especially Car Home cause along with people on XDA i have also noticed that it does use a fair amount of battery for NO Reason.(Be careful with My T-mobile and My Device might throw your phone into a force close frenzy)
--For some reason people have been asking exactly what T-Mobile Apps you can freeze/uninstall and the answer is. All of Them. I personally left My T-Mobile(To view Minute Usage) and Wifi Calling(Cause I have no service in some buildings) and froze the rest, but you can get rid of everything you don't want or use.
Third -(Root Needed) Set CPU. Have had this on my G1 and N1 and it does nothing but save battery. I currently have it set on 216 - 1000 for when the screen is on and the only profile i have is for when the screen is off and it is at 216-216.
(Alternative) Pimp My CPU. I now am using this for my G2x because I am running custom kernal. Personally I like Set CPU better, but do to the fact that Set CPU can't get past 1000 MHz makes it kinda useless for the G2x Tegra 2.
Fourth -(Root Needed) Battery Calibration. There is an App in the Market for this and it is easier and less of a hassle than Factory Reseting the phone. Just charge all the way to 100% and i discharged to 0% and recharged it and Amazing difference in battery life. (And don't doubt the Calibrator cause right after i set it to calibrate the initial 100% got to zero in about 7 hours, but after that one cycle i was getting the 20 hours i am now)
Fifth - Elixir. Not only does this app display anything you might wanna see about your phone (CPU usage, battery temp, battery percentage, memory...) it also has a widget that lets you toggle your internet on/off. Which is almost necessary since "4G" kills battery like no other.
Sixth - Auto Sync. I shouldn't have to put this, but if you don't know your phone is set up to auto sync all your Google apps(Calendar, Gmail, Contacts) and Social Network apps(Facebook,Twitter). So go into settings and make sure that you turn auto sync off.
Now the next steps aren't proven to give extra life, but i did them just in case and well I get 20 hours of use like i said before.
Sixth - Watchdog. This app monitors all the other apps and processes in your phone and will alert you if a rogue app is draining your better life.
Seventh - I did the "Alternate Battery Fix". This involves changing one setting and who knows maybe it does help me get extra juice.
Link: http://forum.xda-developers.com/showthread.php?t=1051036
Eighth - Wifi Never sleep. Supposedly according to some if you change wifi to Never Sleep it will stop some loop in the programing which in turn will save battery.
Ninth - Wifi Calling. If you didn't decide to freeze/uninstall this app. Make sure that this is OFF, because whenever you have wifi on it will constantly flip between Wifi Calling and normal radio towers, which once again is bad for your battery life.
Well, Thats that and if y'all can think of anything that i missed or have any questions or ideas let me know! And remember this is a Dual-Core, High-End, Monster Phone and duh if you use it hardcore (Movies, HD Games, tons of web browsing) the battery will die fairly quick.
P.S. Will post a Screen Shot of Uptime for 20 hours later(if it doesn't Re-boot before i get to 20)
Update #1: Have read all the posts and have decided to speak up about a couple things.
Task Killers - I feel like these are brought up in every thread ever created about batteries, and well they are useless. So, if you are gonna bring up the ram usage argument. Android is made to kill programs that are either inactive for to long or the operating system will shut down background tasks if a new app needs the cpu power. Than for those who say that it helps close programs and makes the battery last longer.Having a Task Killer that basically re-closes the same apps over and over again(These are usually bloatware background apps that for some reason never stop running) is not gonna do anything except waste precious battery life on running the task killer itself cause the app will just restart. Your best bet is to run watchdog find the apps that are taking to much battery and freeze/uninstall them.
Managing Apps - Apps like Tasker, Juice Defender, and the like are in my opinion not battery savers at all. They are just tools to implement what i have already previously stated, but that doesn't mean that they aren't useful. They are good if you have a busy schedule and have to constantly turn the internet on and off or switch between certain settings, but they are not actually a cause of better battery just a tool to implement what you could do on your own.
I've done most of those things over the course of the last week and I just got a little over 24 hours on my last charge.
Those tips are legit.
Thanks! I was kinda worried about it cause it was my first post!

Great job! I've been getting about 20hrs of battery life using some of these... now I have more tricks to add =-)
Good job! I'm almost done withall the tweaks and have say it helping. Thanks

Great tips. I was doing most of those, but have added the calibration software as well as watchdog. I have also found Juice Defender to be a big help.
Thanks again.
this is still not acceptable for a phone in 2011 to still have that kind of battery, most people out there aren't really concerned about tweaking their phones or dont even know about it. Im not gonna use setCPU or anything else, i expect things just to work flawlessly out of the box.
Tasker can be a friend in this whole deal too.
If you can automate your radios & screen brightness to exactly what you need when you need it you can save significant battery life.
If your WiFi calling app can't stay on wifi, you need to fix your wifi network and not your phone.

With all of these changes having a toggle for haptic feedback I assume would help a ton...considering its a touchscreen and a retardedly fast phone. Otherwise it vibrates on every damn user input. Just curious what others think about this. Anyways, thanks for this post....the forum is getting congested.

Yeah, but on the flip side your an early adopter for technology that literally JUST CAME OUT and so there is no perfected system for it. I mean the version of android we are running right now doesn't even truly support dual-core! So yes this is the price we pay, and if dual core had been out for two years I would completely agree but it hasn't. This is what android has always been built on a semi flawed system but top of the line technology and thanks to the great community we have we can push the limit of every device out there even the g1.

I meant this for people like myself who live in an area ( or college like me) where you are constantly moving in and out of wifi range and that would take a drain on your battery.

I think the reason we have so much haptic feedback though is because we are lacking physical buttons and the small vibration gives us the sense of a solid keyboard even though as you stated everything is a touch screen. Well that is my 2 cents anyway.

Tasker can be a friend in this whole deal too.
If you can automate your radios & screen brightness to exactly what you need when you need it you can save significant battery life.

I will definitely look into tasker and check it out personally and add it to the list later! Thanks!
Update: I have seen programs or apps like this before many moons ago i used a program called wisyncplus and basically it is just profiles. This I guess could be used to increase battery life, but in my opinion apps like this and Juice Defender and what not are simply 1) too much of a hassle - cause you have to usually set up each profile individually 2)This is more of a convenience - It doesn't actually increase battery life it is just a manager almost like a widget.
Than back to your argument about the screen brightness my auto-adjust does just fine depending on the lighting and honestly in less your watching a movie, playing video games, or doing intense web browsing your more than likely not even gonna have your screen on that long. (and to those of you that say the Auto-Adjust doesn't work remember that this is an LCD screen it is lit from behind so it is gonna seem brighter unlike the Nexus S which is lit in the screen making it viewable with less brightness)
Than for automating radios honestly there is already widgets for that. The stock rom comes with a Wifi on/off widget so no complaints there, and elixir(which is a free and very useful app) comes with a apn off/on widget which is really all you need cause in my experience unless my internet is on I see no difference in battery life being GSM preferred over WCDMA preferred.
So in less you really do have a tight schedule, or just don't wanna mess with changing settings manually(and with widgets), Yes, Tasker is perfect cause it basically does everything for you.(even though i am pretty sure there are free apps exactly like Tasker)
(Sorry if this came off kinda rude I don't mean to flame at all just trying to say all of my opinion and back it up as best i can)

this is still not acceptable for a phone in 2011 to still have that kind of battery, most people out there aren't really concerned about tweaking their phones or dont even know about it. Im not gonna use setCPU or anything else, i expect things just to work flawlessly out of the box.

if this is the case, i don't think that an open-source phone is for you. the beauty of android is that anyone can personalize it and tinker with it.
the g2x is sort of like a muscle car- it has lots of [dual core]power, but the trade off is trying to manage battery life.

I think the reason we have so much haptic feedback though is because we are lacking physical buttons and the small vibration gives us the sense of a solid keyboard even though as you stated everything is a touch screen. Well that is my 2 cents anyway.

For the sake of min/maxing battery drain I would think toggling the vibrate after every input would help. I actually like the keyboard without it pulsing all the damn time. And my hearing might be a little sensitive to where I dislike the fart sounding vibrate motor. Haha.

Couldn't have said it better myself. This is exactly why I am a huge android supporter/early adopter, a car fanatic, and a Mechanical Engineering major. Because I love the individuality of it all and to be able to own something that can be unique to me.
Wotornot said:
With all of these changes having a toggle for haptic feedback I assume would help a ton...considering its a touchscreen and a retardedly fast phone. Otherwise it vibrates on every damn user input. Just curious what others think about this. Anyways, thanks for this post....the forum is getting congested.

I dont think turning off haptic feedback will really make to much of a difference in terms of battery use.
Our phones are dual core phones, in every test run dual core phones have less of a battery draw because two cpus is better then one. When dealing with a multicore phone/computer the device can have more power without using more energy because there is less stress on the cores. The old way was a bigger battery drainer then this because 1 core would have to use more energy to produce equal amount of power that a 2 core setup would. As spencer said and we have all been saying its more of a software issue then a hardware issue. Imagine loading a computer with 24gbs of memory and have an core i7-Xtream chipset and using windows 7 32bit its pretty much a waste. I believe a lot of the issues that everyone is experiencing will be fixed by a software update or the dev team when roms of the gingerbread nature come out.
Spencer nice post btw!
Ok, I realize this is beating a dead horse, but the battery life in my Droid Pro is beyond pathetic. I actually burn through a battery (with light to moderate usage) faster than I can charge one lol. I am on my third battery today and it's not even noon. I'm in the red on the third one and the first is still not done charging (using a separate external wall charger). This is stupid.
Androids going through battery really quickly has always been a complaint, actually I hear that complaint about almost every smart phone. In my android experience, If I pull my phone off the charger at 8am, it should be about dead by 8pm, if I have only used the phone minimally. If I'm listening to radio, or playing some games, or just keeping my phone awake for a while, my phone will be dead by 3-4pm.
Your case seems a little extreme, and all I can recommend is using a power widget to turn on and off all your basic stuff. turn the brightness all the way down if you don't need it, or try auto. Keep bluetooth, wireless, and GPS off until you need it. Also, personally, I only let my phone sync while wifi is on, otherwise leaving sync on all the time kills my battery. All I can say is do the basic things people recommend to extend your battery life. I know with my first android phone, I kept everything on, all the time, and the battery sucked horribly, but turning them on and off through settings was really annoying to do everytime, so with a widget on the desktop for that stuff I don't mind it at all anymore.
You also just may have an app or two that's destroying your battery. I can't recommend anything off the top of my head, but there are apps that give you a general idea of where all your battery is going.
Yeah, I keep GPS and bluetooth off. Also, I downloaded the app killer and hit that several times a day. What I don't get (total droid newbie here) is why, when I hit the app killer, it says that it killed 13 apps. 13 apps? Why in the world are 13 apps running? The phone is just sitting there. I'll hit the app killer again (20-30 minutes later) and another 12 or 13 apps get KO'd. It's crazy. But yes, I know I've got something stupid going on but I guess I'm just too dumb to figure it out. I've only had this for a couple of days and, as my ID suggests, I came from Blackberry.
Get rid of app killers, Android 2.2 and beyond do not need it, you're doing your battery worse.

This battery life issue is what's going to bring Android down. Google needs to get a handle on it because the more and more people who come to Android from iPhone or something else and experience this issue will inevitably have a less than content experience.
You are right, this could be a deal breaker for me. Yes, the blackberry browser sucks, but I'm seriously teetering on whether or not that is the lessor of two evils. I'm on day four with the droid. Granted, I haven't spent a ton of time dissecting this device, but I don't really have a ton of time to give...nor do I want to carry a half dozen batteries with me

Does the newer software kill the app when you leave it? I know with the Blackberry, you had to close the app or it would keep running in the background. I really have no clue how the droid works. Forgive me for being so droid retarded, but I've had no formal training lol.
And, BTW, this is the first electronic device I've bought that came with no manual. To me, that's super funny!
Android 2.2 only kills the application if the memory goes below a certain threshold to keep the system from clogging up.
yeah...android phones' battery is a bitterly troublesome issue!
Honestly, sounds like some faulty batteries here. I have a Desire HD and I listen to 2 hours of music and play close to an hour of games with another hour of web browsing a day on it. I tend to make perhaps 10 minutes of phone calls and I have autosync on for my gmail (but nothing else) and I dont have to charge it during the day at all. I am however in strong signal areas which makes a massive difference.
I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.
What is the difference between a widget and an application?
An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.
My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use
whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|
Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.
ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.
the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.
If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.
Cheers! (Extreme power user).

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!
Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.
There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life
Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.
Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said
I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.
Hello everyone,
So I've noticed some people have been complaining about the battery life on their phones, I've gone through the same woes and complaints with every Android phone I've ever owned. Here's what I do do get a much improved battery life... Some of this is non specific so you might need to find out if your version supports these features. None of this requires root access.
#1 First thing I do with any new phone is catch all the updates, not through the Android OTA feature, but I'll run it through whatever recovery software that the manufacturer has available to get it up to speed with the most recent version.
#2 After the update I'll carefully charge it to 100%. By carefully I mean not leave it on the charger overnight or for more than a couple hours after it hits 100%. Don't let the charge drop below 20% and don't charge it beyond 80% for a few days unless your device has a smart charging feature like ours does. The system is learning out habits.
Also, be sure to use the charger it comes with. Anything else might charge it in Turbo Mode and while our devices and batteries support this feature, be mindful of your use. It could possibly cause the battery to loose capacity more quickly over time.
#3 Keep Bluetooth and Wifi off if you aren't using them or you don't live somewhere where you're able to grab hotspots on the go (Comcast, Xfinity, these have so many hotspots in some big cities -Chicago does - it might make sense to leave them on here to save on data. Make sure if you're using Xfinity that you research creating a hotspot profile so your phone can do it automatically - there's an Xfinity app for that)
#4 Our phones also have an option for "extra dim" screens. This finesses the brightness just enough and should save power too. Please be mindful of your eyesight though.
#5 Heavy users - gamers, having Facebook polling for updates, and other programs can be working hard in the background. After a few days to a week, I'd check your battery stats and see what's eating up the charge and potentially limiting those apps or install the "lite" versions.
#6 Less nervous fiddling with the phone. I'm one of those people who have their phones in hand all day long. I started putting it down when I wasn't actually using it, and keeping it in pocket or elsewhere. Too much playing with the keys I noticed I was constantly turning the screen on and off. That will definitely use up a little more charge. Don't worry, your phone won't miss you! It's ok to not pay attention to it when it's not in use. It'll let you know when you have a text, call or whatever if you turn the volume up
That's about all I do on my phone and I easily get a full day if not more (unless I'm excessively playing a game all day). This has been true for me on any Android phone I've owned across the board since using this approach.
