Is there something wrong with my battery?

Well I just switched to Android and I'm loving it! It's awesome. However I'm really having a problem with my battery. I got this phone on Sunday...and the battery life for me has been horrible for me.
I leave my phone on the charger all night. I have to leave for school, and I take my phone off the charger around 8:00am.
Throughout the school day, I'll check my phone a couple times. I probably send like 10-15 texts, and I take a few pictures at lunch. That's all I do, nothing else. By the end of the day (2:45) the battery is at 50%. I don't understand how a battery can be this bad, when it's in standby almost the whole day.
I have advanced task killer installed, and I have it set so all apps are killed when the screen is off, and it auto-kills apps. I turn off wi-fi at school since I don't get any, and my screen brightness is at auto. No live wallpaper either, just a normal still one. So I have no idea what I'm doing wrong. I understand the battery isn't the biggest, but from what I hear everyone else is getting better battery life then me, and they're doing so much more than me.
Any help? Would be appreciate!

First things first, get rid of task killer. Also see what's syncing. Play with the settings a little. Battery is tiny for this phone. But with tweaking it does the job. Best bet is to get a second battery or an extended battery from the desire hd.

Why should I get rid of task killer? Everyone that I speak to that has android told me to get it. When I don't have it, I have all these apps running in the background like Asphalt 5, AT&T Navigator, Maps, and a bunch of crap that shouldn't even be running. I have pretty much everything syncing, does that kill the battery?

Taskiller was ok back in earlier versions of android. The apps aren't actually running they are stored in memory with no impact on CPU. Constant syncing is going to destroy your battery.

Davwman is absolutely correct about the task killer app. Do some googling on this and you will see that it creates more issues than helps.

Alright, thanks a lot! I fixed the syncing, and a message popped up saying that it will extend the battery life. I'm going to assume this is going to help a lot, since Facebook and my email was probably constantly updating during. I'll look into the task killer as well!

You should see an improvements in the following days as well as the battery is settling in.
If not, Id ask AT&T for a replacement of the unit for another one.

If you have any battery widgets I would remove those too. I had batstatt and it was destroying my battery!!!

The battery isn't too great... 1230mAH ... I did send an e-mail to HTC regarding replacement batteries and they said I quote..
Dear Sean,
There's absolutely a chance of extended batteries being made; plenty of our devices have them made for them. At this time I don't know for sure if we're going to have one, as that decision is made by a completely different department and the Inspire 4G has only been available for less than a week. If we are to have one available, you will be able to find it at shopamerica.htc.com. I hope that we have one available as I know how useful they can be.

You really need to turn off auto-brightness as well. That will suck up battery power. Just set your brightness to a reasonable level. I usually keep mine around 35-40%

also auto rotate and data always on could affect it

Look into a widget that will allow you to kill data when you don't need it. Switchpro is a paid app and will allow this but I'm sure there are free ones.
You will still be able to send and receive calls as well as sms.
This should help get more out of the battery life.
As previously stated you might also look into picking up a spare battery for when you need the juice.
Check amazon and ebay. Beware of anything coming from China.

This.
Everytime your screen adjusts, its using CPU. So turn it off, get rid of the task killer,- when you kill them, chances are most of them are starting back up and that's making it worse.
Flash/ or wait for a version with all of this horrendous bloat removed.
It will get better
I'm actually pretty happy with mine.
I'm at 15 hours off charge, exactly 20% battery left, 3 hours screen on time

turn off syncing. dont us gps or navigation programs. no live wallpaper. i use this phone like my old Tilt 2 and i get about the same amount of battery life out of it (1 day) and i charge it at night. now on my phone i have syncs running for email and facebook and what not i send and recieve about 30 - 50 txts a day. lots of email. photos for work, i DO have live wallpaper loaded so i think the battery is just fine. however yes i will want a bigger battery when this one dosnt accomplish a full day without a charge.. oh ya games will eat into your battery as well!

Amazing battery life!

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...
Bleeds

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.

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.

Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you

I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.

Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..

I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...

Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.

I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.

Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours

neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.

Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.

Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.

you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.

My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

what i did to get 4% battery loss an hour

*edit: i posted this because i'm actually happy with my battery life*
1) install setcpu and have profiles-- screen off 216/216, overheat 216/600, and a sliding scale based on how much battery is left
2) uninstall battery monitor widget, and instead use anycut to put a shortcut to battery info on my home screen.-- i realized that i was running down by battery by constantly turning on my screen to look at this beautiful widget. therefore, i found an even less battery consuming option AND i limit myself to checking battery percentage once an hour
3) turn down screen brightness completely in the evening and in well lit areas-- aka work.
4) use titanium to freeze bloatware. it was brought up how this bloat showed up in running apps still and i used bloat freezer to freeze them again. HOWEVER, bloat freezer for some reason, made my battery life worsen, so i uninstalled and went back to titanium. however, now, these apps do not show up in running apps, but i have "lost" my account. i.e. can't find it to unfreeze if i wanted to.
5) used battery calibration and ran the phone down until it died, and then charged up completely while off, two nights in a row...
6) changed the secret menu to "auto"
7) removed the music player widget from my homescreen, replacing it instead with a shortcut to my all music playlist
things i did not budge on
there were things that i could've cut down, but would have, in my opinion, dumbed down the phone.
1) autosync both email addresses
2) beejive im is running at all times with push notifications, alert on the first message
3) words with friends also has push notifications enabled
4) i use shopkick constantly
5) "4G" service- its what im paying for, and i enjoy the extra speed, so i never turn it off.

First of all, only calibrate your battery once. The phone needs to take those reading for the battery to drain evenly. It can take awhile for it to read the entire battery. So just charge to 100 percent, clear battery stats and leave it for awhile. Secondly, 4 percent in an hour isn't all that bad. it should be more like 1 or 2 percent but 4 isn't terrible.

What is the secret menu?

I'm losing around 10% per hour.... moderate use.. I calibrated the battery once, and I don't really have any apps in the background. I also froze apps using BloatFreezer. I have no idea what to do at this point.

going to try this tomorrow morning, the phone prior to this replacement was dying in 5 hours with no use and data turned off while I was at work, that is terrible I would be happy if I get 10 hours, haha.

I recently bought the g2x and I must say I'm very disappointed in the battery life. How do you check what the battery % loss per hour?

Thought that maybe there is an app for that....

If there is, not sure what it is haha, but I rather just not download an app for that and just use math But really, the battery life on my phone is horrible, part of me wants to return it under buyer's remorse and part of me wants to wait for gingerbread to see if it works? Not sure what to do. I don't want to end up sticking with a crappy battery life phone.

So how do we access the "secret menu", and what do we change to auto?

for your 4% drop per hour, what was your phone usage? did you pretty much leave the phone idle or maybe 20 min of usage? that makes a big difference

I'm also getting around 4% per hour. Decent usage too (little over an hour of phone time with bluetooth, couple hours of web browsing over the day, alternating between wifi and cell radio). I got this through a battery calibration only.

This is an average of 4% drop over an 8-9 hour period. Over that time, I probably talked on the phone for about a half an hour, had iming running, so iw ould answer ims intermittently- probably 20 mins of iming, scanned a few things and checked in using shopkick, browsed for an hour cumulatively, read emails as they came in, and read and answered maybe 20 texts?
i would say that is medium/light usage. since i am in and out of meetings, i would only get a 1-2% drop some hours, and since i was talking on the phone, a bigger drop then...

First of all, only calibrate your battery once. The phone needs to take those reading for the battery to drain evenly. It can take awhile for it to read the entire battery. So just charge to 100 percent, clear battery stats and leave it for awhile. Secondly, 4 percent in an hour isn't all that bad. it should be more like 1 or 2 percent but 4 isn't terrible.

sorry, i reworded my post to first say that i did not run battery calibrate twice.. also, i too agree that 4% an hour isnt bad. what are you doing to get 1-2% an hour?

What is the difference between the standard setting and auto in the secret menu?

There is it's called Juiceplotter.

1. i dont believe in those "power saving" apps because sometimes they use just as much battery as it saves.
2. what the point of having a smartphone, or even a cell phone, if youre always on airplane mode?
3. i posted this because i am actually happy with my battery life.

I need stats from a poweruser. People keep reporting 20+ hrs but realistically u let ur phone sit for the whole d day and text once or twice. I use my phone all day. Thats what I bought it for.

Extreme measures for better battery life

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.
