Battery Life: 1d 12h? - T-Mobile LG G2x

Using Faux rom (Kernal version 2.6.32.41-CM7-Faux123-v0.2.3)
I was able to get a crazy amount of life out of the G2x! Anyone else able to get some times like this?
When I first got the phone it would only get about 4 hours.

i've been on 11 hours, Nexus AOSP, and am at 85%

With SetCPU and underclocking when idle or on calls?
Is Juice Defender involved?
Exclusively on GSM?
Are Auto Sync and GPS off at all times?
Please provide context.

Yes, setcpu and some UC, phone goes to min processor on screen off
Juice defender set to standard
data set to auto
auto sync gmail, gps only on demand
note today was a very, very light day of use. Yesterday I used it moderately, checking emails, maybe a call or two and several hours of music and was at 50% after about 14 hours.

I have tried virtually every ROM and kernel combination for the G2X and for my phone and usage pattern I have had the best luck when I returned back to CM7, currently RC1 without OC/UV kernels, without SetCPU/PimpMyCPU, and without Juice Defender, or any similar such programs. My gains appear to be achieved by better efficiency with the screen off. The only modification that can be responsible other than CM7 itself is that I have the phone 2G only unless I need 4g at which times I turn it on manually. I think this is the actual cause of most of my better battery life.
Recently I went 32 hours of light usage (maybe an estimated 3 hours of phone calls and 2 hours of actually performing some task in Android) and was at about 35% battery life (although I believe battery percent is totally meaningless on this or any GB Rom for the G2X). I can easily make it sun-up to sundown with moderate to heavy usage unless it involves lengthy playing 3d video games or similar cpu/video intensive tasks.
When I first had the phone (completely stock) the battery would run out before 8 hours even if I didn't use it at all. I think I was getting great battery life with the AOSP ROM (Faux) and Eaglesblood ROM without modification. I am came back to CM7 rather than those others for purely aesthetic reasons.
My conclusions are merely based upon extensive trial and error and subjective impressions. I am not an expert at anything, except perhaps backgammon, lol

2g only is not a fix in my opinion. I purchased a 4g phone for a reason. The software and drivers are still an issue. I get a solid day (12 - 16 hours) out of a single full charge with 3 email acounts checking every 30 min. Surfing the web and a little game play for fun. The screen is the biggest draw on the battery. My battery monitor shows a direct corolation to battery draw and the screen on.

I understand your point, but how often are you actually using 4g. It is not necessary for syncing email or other background tasks, in fact on my phone Pandora runs the same on 2g as 4g. And when you do need the performance of 4g it is 2 clicks away, one swipe to pull down the notifications and another to toggle from 2g to 4g. It connects in about 10 seconds, for me anyway a shorter period of time than it takes me to figure out what I'm doing. 4g appears to be the biggest battery draw with screen off. If you use JuiceDefender you can program it to turn on 4g whenever particular programs are launched.
You are right about the screen it is certainly the biggest draw with screen on. I run a bike computer with gps program. I run it with screen at full bright constantly on, gps running, plus using whatever small amount of use the program uses to operate. At this rate the battery runs out before 4 hours are up.
Oddly making phone calls appears not to drain the phone at all compared to other activities. I've taken my phone of the charger and made a 1.5 hour phone call and hang up and the phone is still at 99%.

23 hours and counting on this charge...

i can get that time on my stock rom one time my phone lasted 1 day 15hrs on stock rom.

I have no doubt, there is nothing inherently wrong with the stock rom as long as you root it and get rid of the bloatware. Getting bad battery life is more a matter of something being wrong, instead of a particular rom being right.
I don't really understand the battery info built into Android, my uptime right now is just over 16 hours and I am at 25%. Which is good as anyone can expect with normal usage. But what is confusing is the usage breakdown, it lists most items at exactly 19%, Cell Standby, Wi-Fi, Dialer, Android System, and Phone idle. Voice calls is the only other item at 6%.
What the heck is Dialer doing with 19% of my battery!?!?

16 hours so far with 20% left.
8 hours of that was while I was sleeping.
While there was some screen-off time for the other 8 hours, the tasks I was doing included redownloading ALL of my apps manually, applying themes, configuring widgets, browsing xda, email, light texting, and a couple short calls.
I am running CM7 with stock kernal. I have like 40 widgets running (probably an exaggeration). I'm running Juice Defender set to disable data/wifi when screen turns off, and enable it for 2min every 15 min. I also have setcpu running. I increased the min to 456 instead of the default 216 because it seems to keep me from experiencing the black screen of death when I leave it higher. My screen-off profile is 456/456, and my in-call profile is 608/608.
Overall, considering that I keep all syncs set to auto so I get instant notifications of gmail and sms, and it takes all of about 3 seconds to turn the data/wifi back on when I turn the screen on, and I don't have to constantly go back and forth messing with 2g/3g. I am extremely pleased with this phone now.

Been unplugged since I woke up this morning...13H 57M and have 40% left.
That's sending many texts, tweets, and using the GPS app for my round of golf today.

currently at 2 days (actually 1d, 23h, 44m) and I still have 30% left. I would say light to moderate use.
Currently running cm7 on nightly 65 with the stock kernal. No setcpu/pimpmycpu or any juice defenders.

What kind of battery life are you getting?

I am getting absolutely horrible battery life on my MT4G. I took it off the charger at 9:30am, I have since made one 5 min phone call and sent maybe 5 texts, and checked a couple emails that i just deleted, other then that screen has been off the whole time, its now 4:40 and im at 35% battery. On my Vibrant with this sort of use I would still be in the 70s.
Under accounts and sync:
facebook updating every hr (just changed it to every 4 hrs)
google syncing just gmail, no contacts or calender
news every 4 hrs
stocks not syncing
t-mobile syncing (tried turning off but it just turns itself on again)
qik video chat syncing
weather every 3 hrs
yahoo syncing
Are you on wifi or 3g? Brightness? Screen timeout? I have an N1 and the battery life is pretty poor so I'm just curious apples to apples in terms of what else you have turned on.

I leave 3g on but i always left it on on the vibrant as well, brightness is at 20%, screen times out within a couple seconds
wifi, gps and bluetooth off
I get great battery life. Then again I am coming from a Vibrant, my battery was horrible on that device. I take it off the charger at around 8 am and by 6 pm I still have 50%

ever thought about turning off 4G? You don't alway have to have it on.
I get around 12-15 hours with heavy usage. My G2 usually gets 15-24 hours.
I saw this article the other day. I was thinking about trying it tomorrow.

Don't bother with that battery charger hack, it's not going to do anything but waste your time...
I just installed SetCPU on my phone just for fun and have found that it recognizes a few lower clock cycles...I added a profile to lower the CPU when the screen is off otherwise at 1024-245 On Demand and I'm still plugging away at 20% battery when I would normaly be on the charger by now...could be a fluke, but so far so good...I'll keep this for a few days to see how it does.
oh, one other note, my battery life has continued to improve with every charge...the first few days I couldn't get through a full day and now I have battrey to spare...just had to get it conditioned with a few charges I guess.
I let the phone completely die last night and then charged it and at midnight I unplugged it. At 8:30 this morning when I left for work it was at 94% which was great but from 8:30 until now it has dropped to 83% and ive had one 3 min phone call and deleted some text messages, no browsing web, no listening to music, nothing. It seems like the phone will go through the 100-95% slowly but after that its in a marathon to get to 0%
I don't know how you guys are getting so many hours daily on heavy use. I get 7-8 hours on heavy texting, some web browsing and about an hour plus on the phone almost every night. 9 hours would stretch it and it would be on 10%.
I have my brightness all the way down and all the way down is just 11. Screen times out in 2 minutes and I have power saving on. I did the battery thing 3 times where I would let it go down to less then 14% or so then charge it fully without taking it off charge. Hopefully it improves as days go by, I'm just tired of carrying my charger to work.

Down to 69% now at 11:15, have made no phone calls or texts since then, have just downloaded opera mobile but havent even played with it...lol this is riduculous
I can recommend that you guys take a look at what might be pinging the CPU. Watchdog (Lite) is great for this task. You can have it alert you when an app exceeds a preset threshold for CPU usage. Some apps just go rogue on you like Palin from time to time.
I've also noticed that there's wide variability in terms of how apps go into either idle or background states. Some apps will go into idle only if you hit the back key to go back to the home screen and will enter a background state (more active) if you hit the home instead. I've also noticed that the free, ad-supported apps require more CPU time. That's right. Hitting Google's ad servers, at least for some apps, and scrolling those ads, requires more CPU time than other apps, which do the same. I don't know whether to fault the devs in this case when coding for the ad retrievals or not. Just some things to consider.
I just got mine. I came from a Blackberry 8900 and an old 2g iPhone. Battery life on both of those was significantly better. I could talk for 8 hours a day on the BB and it would last until midnight-1am or so. The iPhone would only last until 10pm.
Using the MT4G, my battery life is REALLY bad compared to these other two devices. I can get about 5.5 hours of continuous talk time, tested yesterday on a conference call for work. But even with only calling for about an hour and some basic email checking, I can't go past 6pm without putting the phone on the charger.
Wifi is off, screen at 50%. Someone please make a big fat 2800mah battery for this thing. I use this thing for work, and I make over 4000 mins a month of phone calls. It's really annoying to have to plug it in whenever I have the chance.
im getting roughly about 15-17 hours and im using it (camera, blogging, facebook uploading)
this destroys the EVO i had
Heavy usage, I'll get around there, 7-8 hours...regular usage gets me around 20 hours..I'm using setcpu w/ profiles..

did you have similar battery problems with your old phone while at work?
i notice my nexus 1's battery is significantly worse when i'm at work since getting a signal is a bit spotty (35th floor) so it keeps searching around. when i'm at home the battery lasts literally twice as long while idle.

Yes definitely right about that. I have better battery usage when I'm off work. My department at work is in the basement. So the signal switches on and off the whole time I'm there.

I think I only brought my G2 into work a couple times so cant really comment on that but in the 3 months ive owned the vibrant, if i used the phone a lot during the day....i mean play games, texts, web, etc..id leave with percentage in the 50s, normally in the 70s, at 4 today i was in the 30s with the mytouch with barely doing anything, since i want it to last until the night i just threw it on the charger. it shows I have full signal (4th floor by window)
My wife just got an mt4g (I have a nexus one). I've noticed that her battery life seems to be just over half what mine is, and I actually use mine more!
When I looked at her Battery Usage display, Android OS was near the top with almost 2h CPU time after being unplugged for 6h. For comparison, on my nexus one, CPU time for Android OS is 4m13s after almost 8h.
Any good way to break that number down more and find out the source of this crazy battery usage?

Battery life is surprising me lately.

My battery has been doing really good lately actually. It makes me feel good when people are like ah i need to charge my phone and i look and i still have around 80% and by the end of the day i still have around 50 or sometimes 60%. My old G1 would be at around 20 by the end of the day. Just thought i would share something positive amidst all the negativity
Sent from my captivate so excuse the spelling mistakes
Add me to that list. Ive been doing some tweaking to see how much battery life I can get . Just checked and after 8 hrs unplug time Im at 94%
what roms/tweaks have you done? how have you used your phone?
1. all black background
2. disabled syncing and background data
3. disabled gps
4. disabled sound and haptic feedback
5. launcher pro tweaks (less smooth animations)
6. threw it on airplane mode while i sat in class
7. eclair. i hear custom roms are huge battery drainers
8. brightness on lowest all the time (disable smart brightness option)
battery performance while on standby is surprisingly good. sure these settings may not allow you to get the most out of your phone but if you are ever in a situation where you have to get absolutely the most life out of your phone you know what to do.

I'm currently on a stock ROM after some trouble flashing something else i just went back to stock with ODIN, im too lazy to reroot right now haha, pretty much i just have GPS off, disable syncing, darker backgrounds, I use the Dark XDA theme,i turn Wifi on when i'm home but other than that i have it off. I', just using the stock launcher, turned off all screen animations- it makes everything seem faster- and thats about it that i can think of right now. i use my phone pretty moderate to heavily on a daily basis. mostly for texting and browsing the internet. I also play a few games here and there when i get bored. Hope this helps
I have found the battery life to reasonable on the phone unless I am using it heavily. For example, today I have had it on for almost 15 hours and still have 58% battery left. This is with background data on, monitoring 5 e-mail accounts, some FB usage, some browser usage, a few phone calls, screen brightness set to medium most of the time, some music player usage, and WiFi set to on all day. I very often during the day unlock the phone and sync my e-mail manually for one of my accounts as it is iffy on retrieving and I have been waiting for something to come in.
ONE THING I HAVE NOTICED TO DRAIN: I have had this issue a couple of times. I am running stock, and when I have experienced unusual battery drain it has been down to the same thing each time. The SnsService has been stuck 'restarting' under the running services list. Stopping the service has returned the battery life to where it should be for me (for example yesterday I was down to 50% battery after about 6 hours with virtually no use. Checked SNS and it was as described above, and stopping it brought the battery life back in line to usual for me).
I typically with light to moderate use get around 24 - 36 hours, but I usually recharge each night anyway.
same here
i even have a spare battery and i rarely use it.
if u disable 3g battery life can last u as long as 3-4 days, only if the captivate has that capability to go 2g with a tap of a button

[Q] New GS 4G user. Help with battery problems.

Love the phone. Only complaint that I have is the battery life. I only get about 10 hours of normal use before it dies.
I have it rooted and I have installed Juice defender and setCPU. I have no idea really how to use either of these apps though.
Can anyone please help me to install and set up the apps that I need to get the best power/battery life ratio for this phone?
Thanks.
A really helpful tip is to use black backgrounds. This reduces the amount of pixels on the screen requiring power on the Super AMOLED display, and will improve battery life significantly. Tower reception is also a big one, just turn off mobile data when you get to a low signal area.
I suggest turning down the brightness to the lowest indoors and then bringing it up a little outdoors. 10 hours is really good compared to the 4 hours I got on my old 4g.

I second the black background.
I also installed widgetoid, created a widget with a shortcut to the mobile network settings.
I have Network Mode set to GSM only (Edge Network) throughout the day. This is fine to keep my email syncing and for phone calls. If I know I'm going to start browsing the internet/ streaming music/ etc then I go and set the network mode to Auto to allow 4G connections.
With a few phone calls and a little bit of internet usage I still had about 60% battery life left after 12 hours off the charger.
juice defender works wonders. Set profile to extreme. Choose carefully and let app do this rest. It auto shuts off data when not using 4 apps. I have been off charge 9:40 mitutes with 79% battery remaining. I've been on the market made a few phone calls, browsed the internet and getting and receiving text + emails coming in. Have settings GSM only until I need 4G speed. I don't need a charger because I get through the day easily.
Thanks
I just wanted to say thanks everyone for the tips! I know more is coming from other users but i'm new to android i switched from Windows Mobile 6.5 and android is better so far or atleast for the week i have had this device. i was getting upset with the battery life and always taking my charger with me(i never had to do that with my custom Rhodium. the black backround idea does work very well. I have also found if you set your backlight timeout to 1 min it helps a lot.

I can tether my Xoom for 2 hrs and listine to pandora over bluetooth for another 3 before it dies... my last phone could berly stand 45mins of pandora over bluetooth before crapping out
Always hated the idea of black backgrounds on beautiful 800x480 screens. Anyhows I had the very same quick battery death too and fixed it. One get Juice Defender, very worth while, second run device in portrait mode [I was an old n900 user so I had it in landscape mode, it did not like staying in that mode]. If things get really bad turn off the WiFi when not in use and change the autosync features to off or disabled. ALOT of power is comsumed by adware communicating with various entities while your away from the device. Genuinely suprused by the sheer amount of adware on the device, nearly ever "free" app is adware [meaning you pay with your usage pattern's etc]. YMV but that all I had to do to get the battery under control.
Im a moderate user and my battery is still going strong

Yep, I'm more than happy getting 10-12 hours of at-office use with WiFi on constantly (including M$ push and personal email) and a moderate amount of browsing during the day. I keep the brightness at "0" as much as possible.
Beats the pants off my N900 which would die in under 4 hours under the same at-office usage patterns.
OEM battery and charger is ~$25 or a Zagg Sparq2 (4 Ah, I believe) for watching hours of video and Angry Birds on those trans-Pacific flights.
You are doing something wrong guys. . .
I'm on a Vibrant /w Froyo 2.2.1 and a 1500mah battery that is now 7 months old.
Battery left says total battery life per charge is 23 hours, 15 minutes.
Now mind you I am a relatively moderately/heavy user. I have 5 homescreens with 15 widgets total on them that refresh every 2 hours, and an intensive live wallpaper.
I use the phone a lot for reading RSS feeds, facebook, texting, and LOTS of music. Total screen-on-time per battery charge is around 3-4 hours with Automatic brightness.
Obviously you have something going on with your phones if you are only getting 10 hours. My phone is also overclocked to 1.4Ghz with overvoltages and I STILL get this good a battery life with all my usage...on an old battery mind you.
Check for rogue apps?
PS: I have Wi-Fi on 100% of the time but NEVER use 3G/HSPA for data since I don't use a data plan. The Wi-Fi is connected 90% of the time the phone is on though since I am always at places with Wi-Fi.

Getting great battery life on my TB... :)

Keepin' it clean by keepin' smooth...
Ok finally after a few days of using my phone it has finally leveled off. My phone has been off the charger since 6am and I am at about 70% charged. Couldn't ask for more out of a smart phone. This is right in line with my Nexus One so I am no longer disappointed.
There are a few tweaks I did make to get this working this way.
(1) Screen brightness set at about 20% - The TB's screen is way to bright to begin with and making this adjustment is something that is not very hard to get used to.
(2) Screen Time out at 30 seconds - Setting to low will get frustrating if you like reading the news on your phone or browsing the web, 30 seconds seems just right for me.
(3) WIFI when not in car (triggered on and off by loss of Blue Tooth Connection and Not In Dock) Using WiFi instead of relying on your data connection will help save some juice while in a WiFi enabled building since your phone will not be trying to constantly search and connect to a data connection.
(4) Blue tooth off until docked - Saves battery by not transmitting a BT signal constantly. I only use Bluetooth in the car so triggered by the dock seemed logical.
(5) Syncing Facebook every 8 hours, News every 12 hours and Stocks (Who really needs this)
(6) I love widgets on my home screens so these get updated as I found necessary to me. Im not a major facebooker that needs to be on the bleeding edge of everyones life so 8 hours is probably even too much but adequate. News doesnt really update very often and compared to a daily news paper 12 hours is more than ample. Stocks, need I say more seriously I am not an investor and could care less.
(7) Over clocking your phone is not necessary right now, 1 GHZ is definitely more than you need on this phone. I am scoring about 1700 on quadrant which is pretty good for a 1ghz phone. My phone has never lagged and has functioned as expected since birthed to my hand. Keep in mind Over clocking will increase the performance of your phone but will tear at your battery as well and may cause heating issues.
(8) Not using an animated wallpaper. Even on my nexus one this was a major contributer to poor battery and phone performance. Animated wallpapers are very often poorly programmed or simply over bloated. Not too mention on the severe end of the priority list of needs. All though cool.
I am not over clocking or installing a custom rom on my phone quite yet because honestly the roms are not stable enough as expected this close to birth, and really don't offer any additional functionality that I find very useful as of yet. I am using Tasker to accomplish a few automated switching routines to toggle WIFI and Bluetooth. I am also using Folder Organizer to keep my apps categorized in a humane manor. I am a widget-aholic and have not really found a downside to having too a lot of widgets running.
How much do you use your phone a day?
Not everyone is willing to cut out their social networking. A big part of smartphones now is always being connected. This includes social networking, sharing pictures, sharing locations... some people get into all of this and some do not.
Also, some people like weather updates, stock updates, news updates, etc. Everyone uses their device differently to fit their needs.
I think it is common sense that the more services you use which consume radio/data/processing time then the quicker you will drain your battery.
Thank you for sharing the setup that works for you and affords you such great battery life. I have been having great battery life too. I am currently not in a 4G LTE area, but the device on 3G has been great on battery. You would never know there are any "issues" if people did not post about them!
What is your uptime, display on time, and partial wake usage?
I didn't check that deep in to it, but I had it plugged in to some speakers at work for about 3.5 hours playing slacker radio from wifi so I could rock at work. I used the phone to call tech support for my wifes phone which took a while and other shorter calls through out the day. Right now my up time is about 65 hours, awake time is at 26 hours. Not sure where to get partial awake. My display on timer only says 1 min. But honestly today was not a big phone use day and it sat in the dock on the ride home so all those stats are irrelevant today. But still my battery it at 83%. A lot of people were complaining about there phones dying with no or little use half through the day. So hopefully this brings a little light to the end of the tunnel.
Dang what were your settings

I've been getting great battery life as well, got 36 hours on my last charge. Have Perfect Storm 1.0, trip's 1.5ghz oc kernel (but don't actually run it that high). I have SetCPU set at 998/245 for normal, 245/245 for screen off and use smartass governor. I was also using my phone a moderate amount but had the 4g turned off as I'm in between 3g and 4g so it just keeps dropping and switching.
Glad to see someone is getting decent life.. I'm about to set a record for battery death.. phone has been on for 1 hour and 20 minutes and down to 65%.
On the bright side I am getting 20mbps down here at school.. SDSU..

It sucks though because on the Droid x, I could surf during the whole 3 hr class and walk out with 50% left.. guess this is the price you pay for this kinda power and speed lol

a couple calls
>20 txts
screen at 15%ish

and now i'm at...89%
I have also found that in the first couple of days (2 or 3 days) after a reset... the phone does a BUNCH of funky things. First night after a reset...VZwireless said at 3AM i had 130MB of transfer... not possible - i was sleeping. it wasn't me. but...i did wake up with >30% of the battery gone. I think the background data off is a good place to start...but definitely wait after a couple of days.
I seem to be getting about 36 hours of up time on a charge. Mostly on wifi at home/work. I have 4G turned off as its not available here yet.

There will be a patch soon to help with the idle 4G battery drain. Lady on the phone told me its in the works. Either way I just got the extended battery today. I actually dont mind the extra size.
Hmm... whats the anecdotal battery life for an extended battery given these settings? I've gotten to the point of running my display at 5% when indoors ==;;;
Also, I've heard of people getting free or heavily discounted extended batteries.... Any tips for this?
I am using an app called fastbright which really helps with the display battery drain...I just use it o bright when i cant see if i am outside....post #10!!! yay!
I've used my phone a decent amount today and battery is still at 62%. Running Das bamf at 1.2 ghz and screen brightness at 100%

I feel the same way... if you are playing around on the tb while it is pluged in it will take a good 4-6 hours to charge to 100%

[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.
How many hours is your phone lasting on a single charge?
Lately between 5-7hrs one had about 8 and half hours a handful of times
it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later
This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?
I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol
Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.
Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!
