I don't understand why somedays my phone and battery will last all day plus some. Then other days battery is worthless (only 9hrs or so) . My routine is the same day to day. I restart my phone every morning when I pull it off the charger. I realize apps and sync etc have affects on battery life. I'm not a newb. Example today phone came off charger 7am, it is now 10:30pm and I have 42% left. This happens one or two days a week. Other days by 6pm I need a charger. Never had a "moody" battery (phone).

I think your usage is different..Although you think you always do the same thing but actually don't..I have the same experience..I was curious for the first time but later i found that day i disable my data and phone works on gsm not wcdma.Also may be different day different apps launched
Do you notice any difference on how often the device is awake? That is what makes the difference from what I've noticed.

From my experience, the battery life does vary as you mentioned. The best way to test is to turn off sync to minimize the amount of battery drain variation. This might tell you if the battery is consistently following along with your issue. Also turn WiFi off if possible. Hope this helps.

The thing is you also have to keep tabs of the apps that you use, most of them BTW don't close/exit completely. (Also abattery drain)
The battery stats are the problem. Seem inconsistent.
How about the possibility that you're in different locations from day to day, and some hours of the day, your signal may be poor, making the phone look for a better signal, draining battery?
My Best Guess is radio modem SUX

This is true. one day I woke up to find my battery completely drained although it was supposed to be idling, I removed a couple of apps I installed the day before that I thought was the culprit and it didn't happen again.
download WatchDog its an app that watches your other apps for insane amounts of memory use and battery drain. Should find the culprit app thats causing this random drain
link to app: https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result
a lot of people dont believe in task killers cause they truley arent needed and to the normal user can cause more harm then good but i like the fact knowing if im not using it, its not running.

First day I got 1d 8h something with 8% left. Next day I got 1d 0h 8m with about 35% left. But I think its deteriorating day by day, not sure yet why this is happening although I made no changes since day 1, data connected all the time or WiFi connected, email sync default settings of 15min, default settings for friendstream, weather, calendar and other widgets.
One more thing I realized, even if you turn off your phone, it is like hibernate, the apps still remain in memory, so I restarted, then I had cleared memory and the battery performance seems improved, still have to confirm this, once I complete I'll post back.
But even now I am getting more than a day, at least 24 hours with the same settings as above.

So I agree with the variation, like the poster 90teggy, even I've been on the same routine, but the battery acts differently.

also explains why person A and B have very different results for the "same usage"... where they live/work etc will have different signal strength. I am lucky, I have pretty good signal both at work and home, so my phone doesn't have to churn thru as much battery.
Get yourself a Anker battery and you your problem with fast draining will be over..
Check this:
I realized that battery drains faster when carried in pocket or somewhat is dynamic state. When I keep my phone flat on a surface, it will stay there hours together without a single % drop in battery.
Only if I carry along, move it, etc. the battery seems to drain.
Just try to observe this and confirm it to me.

As you move around it's probably seeing & trying to lock on to different transmitters which can cause increased drain.
Different transmitters?
No, its just when its in Pocket, either you sit or stand, drain will be considerable.
Same you keep it on a flat surface, it stays at the same %
My Sensation gets great battery life most of the time, but in relation to your comment about putting it in your pocket - sometimes when I walk around with my Sensation in the pocket of some shorts (where it can swing around a bit more than in jeans) the next time I take it out of my pocket it's very hot and seems to have frozen up or be in some kind of reboot loop. This has happened to me five or six times ... with different pairs of shorts
Get the battery pack for Htc Evo, root your phone and delete batterystat.bin. Worked for me.

The WiFi & mobile signals will be weaker when in your pocket because your body will block them a bit. That will increase drain but to what extent is debatable

On my stock Sensation battery drain on idle with display off is 200mA average.
Barely lasts a day on full charge with light use.
On my HTC HD2, which is rooted with Android rom installed, drain on idle is around 40mA average. It can last two days in idle and easily all day with light use.
Something is draining Sensation battery hard. Can't find what. No matter if phone sits stationary or moving in my belt pouch.
I suspect some TMos apps running in background.

So the screen is supposed to have less drain on the battery? Why does it drain 80% of the battery consistently? So if this phone had a regular lcd screen it would only last 3 hours?
When I'm at work the service sucks and my phone is constantly searching for signal. The battery went down two % in a minute and goes down 5-6 every hour if not more when not using it. At home I don't have this issue and I get much better performance. I pimped my phone out and I feel like this is the cause of such short performance. The phone is much more responsive and I love it but if I want to make it through a day I can hardly use the thing. Just posting this thread caused my phone to go down 4%

lol switch to the dell streak or the evo, you'll then truelly be able to appreciate battery life on the captivate.
in general though, it seems like you're having some bad luck with your battery. Some users suggested doing some power cycling and a factory reset of the phone. I also highly recommend reading the pimp my captivate pdf. Nifty little section in there for battery optimization.

When was your phone purchased? If you registered it, did you happen to notice the manufactured date?
if your phone is on standby, when you go to settings-about phone-battery- What is eating the battery?
My first Captivate would drain the battery (even in "standby") about 2-3% per hour. Even though the phone would be on standby more than on, the DISPLAY was eating the battery life more than "cell standby"
my 2nd captivate - battery is lasting much longer - took it off the charger Friday at 7PM - am currently at 34% - and I've used the web browser/navigation/browsed the market, made phone calls, etc)
When I view the battery settings, "cell standby" is first in line..
Also, when I do keep the phone on standby, the battery BARELY drains.. I'm talking maybe 1% for 3 hours
Oh, the GPS works on phone #2 as well. My 2nd phone was manufactured 7/20, first phone was 7/10

If you went down 4% just posting, then it sounds more like a battery issue. Can't really help you there. But the crappy service at work thing - have you tried seeing if flipping from 3g to edge helps? In my office, my 3g signal is bad - 0-2 bars, constantly fluctuating. If I filp to edge, 4 - 5 bars the whole time. You could definitely save some battery there, if it worked for you. Here's the thread for changing to 2g: hxxp://forum.xda-developers.com/showthread.php?t=737137
FYI - Checked battery at Midnight last night- battery status was 32%
Battery is STILL at 32% this morning.
If my phone is idleing, i hardly lose any battery percentage.
I use Juice Defender to help my battery. i can easily get 2 days out of it if I use my computer to browse the web, but sometimes it's just easier to use my phone if I am at home or laying in bed.
Some of you are getting some very impressive battery life, I cannot seem to compare.
My battery went down 5% over 6 hours. Which is a huge improvement over the 30 percent it did before.
My phone has been off the charger for 15 hours and 26 minutes. About 8 hours of which I was asleep and the phone was in standby. My display is still listed as #1 in battery history at 52%, I don't understand how anyone gets the display out of the #1 spot.
if you don't use the phone, it wont. I've had it where my display and idle were about the same, but that's because i haven't used it.
If you make a phone call, the display will turn off and your cell service will take over the #1 spot.
The display will drain the battery the fastest. Even if it does suck less juice than before, it is still more than android needs to run. If you take the display away and give it a black and white that you find on E-Readers, I bet this phone would last for days and days. You are paying for a 4 inch screen that is gorgeous. Of course it is going to use battery life. There aren't any other ways around this.
EDIT: I'll play around with it for the next few hours while i'm hitting golf balls and then I'll break it all down and we'll see how my battery has been affected.
For those of you who don't have there screen with the main drain what do you have it set at? I have auto brightness on and power saving on. Maybe these cause more problems. With the screen constantly adjusting our drains more than it save s

Voice calls is in first at 52% and display is at second with 38%. I get amazing battery life out of this device. Again I am comparing this to a BBC bold.
My battery would drain down twice per day.
If I was going to turn off background data, browse on my PC, and micromanage all the settings... well, I wouldn't have gotten a smartphone.
I would have preferred a slightly thicker phone to go with a larger battery. Samsung had the option with the BlackJack with a bigger battery & second battery door.

1500 mah is the largest battery in a phone yet. I am sure someone will release an extended battery which will also add thickness.
Typical Android devices get terrible battery life from what I have heard.
I'm not at all surprised that my display is the #1 factor in draining my battery. I bought this phone for its display.
What I am surprised to hear are those people who own this phone, use it, and don't have their display as numero uno in their battery history. I have to imagine they either: 1) don't use the phone all that much (e.g. have it in standby most of the time), 2) only use it for phone calls & texts, or 3) have their brightness/other settings set up uniquely.
I'm most interested as to whether #3 is true. If that's the case I'd like to find out what those settings are and try them out myself.
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

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.

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.

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.
So i tried what you guys suggested. I rooted the phone, bought setcpu, using anttek to freeze running services, and used the battery calibration app still NOTHING. I just woke up and my battery was at 0 before i went to sleep it was at 62%!! How can it die in idle with no running servislces wi fi off gps off BT off i mean it has to be the battery right?

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

If you researched the problem and tried the solutions offered, then the logical next step is to contact T-mobile for a replacement. This is an early release of a new phone; there will be defects. And you don't have to settle for a defective device/battery. I can assure you, I get battery life on par with my previous phone (8-20 hours depending on my usage)..so, bad battery life isn't a problem inherent to the phone. And my phone doesn't get warm with data usage. It sounds like you might have a defective battery or phone. If you aren't satisfied, don't settle...make 'em make it right.
I get about 5-10% battery drain overnight most nights and I am not mindfull of what apps are running or what is on. My experience obviously differs from yours. I do get great service in my bedroom where the phone is overnight. The other night I did experience a bout a 60% drop when I left the phone in my daylight basement (underground). I get crappy 2G service in my basement and it looses signal a lot. I think it adds some credibility to the searching for service slowly killing the battery. maybe try putting the phone in airplane mode before going to sleep. That should give you some indicator.
I'm now are 28 percent after 3 1/2 hrs with the display only using 13% if that..

You might have a bad battery or something. My first g2x rebooted constantly and drained the battery and got hot.
New one goes 8am to midnight with 20% battery left, on moderate usage. And even at the 20% left i can leave it overnight and it'll still have power in the morning.

The phone is going to get warm is use because the CPU is under load and that produces heat. As long as its not overheating this is normal.
Have either of you tried the factory reset? That fixes the idle drain for most people.
Also... Your phone is going to drain battery faster while actually in use no matter what you do. The LCD and data connection are the biggest battery drain for smartphones. Until battery technology improves, there is nothing that can be done about this. But like I said try a factory reset and you should see your idle drain improve dramatically.

I've also noticed this. In the morning my battery life is decent but by the after noon I can do light web browsing (10-20) mins in an hour and loose over 15% tmobile told me that isn't good lol I have a new battery on the way.

Were you on wifi? Because if you weren't that much drain is within the norm. Web browsing = constant data connection = more power consumption = faster battery drain.
I had 10 hours of heavy use yesterday and had 25 percent left... 2.5 of those were in airplane mode cuz I was flying from Phoenix to Atlanta but I watched a movie during the flight and had music playing the rest of the time... during my layover which was 4 hours I browsed the web, watched a stream of the Celtics vs heat for a bit, more music... I plugged back in with 25% left and had 3h20m of screen on time... this battery is freaking awesome! I had drain issues initially but they went away and now I'm golden
when i did a factory reset, my phone was getting hot until i remember about the *#*# thing and changed that to wcdma/gsm auto. then my battery life got better.
Get juice defender. Its work wonders for me and my buddies thunderbolt actually makes it through the day now

Battery Drain is mostly Cellular radio
I too am have been looking for a way to have this phone last at least 8-12 hours with normal usage, but I don't think its going to happen unless there's some major update to the radio firmware coming in 2.3 Gingerbread..
All the evidence seems to suggest two culprits... for battery drain.
- First is the 4G radio, look around at almost ALL 4G enabled phones (whether on GSM at&T Tmo or Verizon), all eat your battery, from the very beginning EVO 4g, Verizon Thunderbolt, Mytough 4G every single one of those phones has the users complaining about horrid battery life. You can confirm this by looking at the battery usage on the G2X and you'll see that the number one use is Cell Standby (that's the cellular radio) on my phone its anywhere between 35% to 60% of total power used.... on kmy nexus one it used to be the display.
-Second, Tegra 2 is more power hungry , granted its a mobile SoC but its mainly designed for Tablets and such with beefy batteries, this is the reason that the Atrix comes with a 1950MaH battery, you can try and use SetCPU to lower the speed, but I have had minimal success.
Here's a test , when you don't need your phone put it on Airplane mode, for 24hours and watch HOW LITTTLE the battery drains.. reason the cellular radio isn't on..

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

I agree. These battery threads are driving me nuts.
Go in the other million threads and read
The thing that is strange to me is how quickly these phones charge. It seems to go from 0% to 100% in well under an hour. Was thinking I should try charging it while off (well, screen w/ battery only).
What???? Having the phone on makes my battery drain? WTFO?!?!?!
Seriously though, I have not experienced bad battery life on this phone. Last night I left my phone off the charger, gps, wifi and wifi calling on, and when I went to bed at 1030 I had 64% battery. At 700 this morning I had 54% battery. Only a 10% drain for me overnight, or a little more than 1% per hour.
All I've done to achieve this is the following (and I realize that supposedly you no longer have to condition Li-ion batteries):
-when I got the phone, I didn't charge it but instead let the battery die completely to where I couldn't even turn the phone on.
-charged the phone overnight w/o turning it on.
-let battery die completely again.
-charged phone overnight w/o turning it on.
-let battery die completely again.
-charge and use phone normally.
I've also rooted the phone and used Ti Backup to remove most all of the bloatware except wifi calling, but otherwise it's the stock rom.
I typically get an entire day of my normal use on this phone. If I use it alot, I have to top off the battery w/ my car charger on my way home from work. This isn't unusual. I had to do this w/ the blackberrys I owned and my evo when I was on Sprint. The battery life doesn't seem any better or worse for me than any other smartphone I have owned, and it's certainly better than my evo or my wife's evo, and both of those were rockin' custom roms and uV kernels.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!
Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

On my hd2, it was like 1% on idle on android, here it seems to be more , like 3-4% on idle.

its funny how some people report 0% battery drain in 9 hours and other get 3-4% drain per hour.....
please post how many charge cycles you went through, its important.
I am personally using HD2 and battery live is amazing. and its only 1250
this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!
Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

Just wondering, when you go into battery stats and extend the graph, does your phone stay awake when the screen is off?...
Mine seems to be awake all the time even though the screen is off.
I got Watchdog yesterday, I didn't notice any apps with high CPU usage...
Me too.. I lost about 8%/hour in 2g standby mode... Totally unacceptable comparing to my previous galaxy s...
Hope next FW update will improve it ..

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off
I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.
I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.
how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.
Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.
To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App
You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.
I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.
I think it's crazy how many people are downing the battery life on the Sensation. I used my phone a bit today. Off the charger at 10AM, used GPS to go to work with Bluetooth activated as well. Forgot to turn them both off while at work. I used my phone like ever 5 minutes checking Twitter updates(also weather/news/facebook/email/etc updates are automatically updating as fast as the app allows. So quick updates for all my apps, GPS and bluetooth turned on all day. Home around 5, watched a few episodes of South Park on Netflix with my phone. Read some news. Played a few different games for about 5-10min each just trying out new games. It's now almost 1AM the next day, and I'm above 40% battery life. I manage my screen brightness, that may be the only thing I remembered to manage well today. While outside/in car, full brightness, inside, as low as possible.
It's shocking to me when I see threads of how the battery life stinks. I'm using the stock battery, I don't even seen the need of getting a larger battery because this already gets me through a day full of activity. Anyone else find the battery life on this device, quite handy? Mine is rooted, but it's stock ROM. I'm also using a skin posted by a member of our forum, the transparency. I'm running the stock T-MOUS(why is it called tmous..? are people that lazy to spell out t-mobile?) ROM, because I accidentally deleted a few apps I discovered I needed back, and did not do a backup. Oh, and I'm also using the battery mod, for the battery icon in my notification bar.
I guess I'm just praising the battery life, is all
I have only had my sensation for about 5 days and battery life is amazing! Im still stock too.. I came from an evo 4g rooted running cm7 and or miui and battery life doesn't come close to being as good as my sensation. Not only is battery life awesome, this phone is awesome. I moved to Southern California a couple weeks ago and Sprint out here is horrible.. so I switched and couldn't be happier. Plus I like this phone was better than the evo series. Battery life is sweet!

You would have to post a screendoor shot of your battery usage and screen on time to completely determine how much the phone was used and how long the screen was on.
Bluetooth and GPS don't use any battery or have low usage (depends on the chipset because some completely turn off) during standby since they're not being used at all.
So we can all praise our phones for having good battery life, but it all depends on usage. If you don't use your phone a lot (you could turn on your screen every 5 minutes but at the end of the day have only like 45 minutes of screen on time and like 70% battery left.) Then you get good battery life. Use your phone a lot and quite simply battery life sucks.

I think it can largely depend on how you use your phone, not just how often or for how long. For example my Fiance also has the Sensation and on her first charge she got 3hrs52minutes before hitting 10% battery. Since then she has only gotten ~2hrs each day now that she has Twitter and Facebook for Sense accounts set up.
That's not good. There's gotta be something wrong with either her phone or something. 2 hours of battery life warrants an exchange.

The phone lasts longer than 2hrs, that's 2hrs of the screen being on. my sensation get's about the same. This is with Gmail on Autosync and Twitter/Facebook for Sense accounts enabled too.
If I do what u did, my batt will be flat in 6 hours. Somethings just not right with my sensation.

You can go by statistics and on screen time and what not. but I just got home from work, and I literally used my phone for about 2 hours straight calling carriers for a customer. I'm above 80%. So from 9AM-4PM, only saw a 20% drain. Once again, keeping BT and GPS on just to see how it goes. ALL of my autosyncs are once again, on, and set to the most frequent can be.
Compared to any other stock phone, this is amazing. Compared to my Cyan N1 and my Cyan NS, it's not a huge difference. Although, at this rate I may give the lead to the Sensation, since I'm leaving all these extra features on throughout the entire day.
good
I get two to three days out of my Sensation, and I'm a relatively heavy Internet user... don't phone much.
At first I wasn't getting great mileage - having to re-charge after only 10 hours or so, but did two things to improve it dramatically...
First, charge the battery once using the following method:
1. charge battery to 100% and leave on charger for an extra hour
2. unplug the cable, turn off* the phone, and plug the charger back in. leave charging for another hour.
3. unplug the phone, turn it on for two minutes, turn the phone back off*, and plug in the phone again. leave charging for another hour.
* when I say "turn off", I mean completely, without fastboot. so either disable fastboot before switching off, or turn off the phone and pull the battery then put it back in.
Second:
Turn off automatic screen brightness, and set the brightness manually to what you need. Ideally, I'd like to have an auto-screen brightness adjustment that automatically sets it, say, 25% lower than what the built-in function does.
That's pretty exceptional. I usually get 13-14 hours with 5+ hours of screen time before I'm at 20%. Using the chichitec battery, btw.
My chichitec battery went 18 hours yesterday before it got to 10% and I charged it. That was with a lot of web browsing, some phone calls, music, games. Id say, medium-heavy usage.
Matt
Same here I have had several Android phones with different carriers and this is hands down the best, on par with the iPhone I had previously with Verizon. No problem getting through the day with Exchange and 2 IMAP accounts and heavy phone use, the only mod is I set screen brightness, battery is stock.

no one is complaining i watch sparticus on netflix and game of throne on hbo go for 5 hrs straight while facebooking random hoes . and i am out of battery..
we are complaining that the 4g drains the phone while on idle.
this is the best battery life i've ever had on a phone. i can't complain at all... i even have gps on and i could never do that before. lol!
Guys, having GPS on doesn't use any battery. It only uses battery when it is active. So for most of you 99% of the time your GPS is off aka standby or whatever you wanna call it.

One reason many people complain about bad battery life is that it seems some Sensation models are actually faulty. Best evidence: TechRadar review.
http://www.techradar.com/reviews/phones/mobile-phones/htc-sensation-943466/review?artc_pg=9
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.
