S amoled screen, cell standby, and battery life - Captivate General

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%

If your phone is constantly searching for a signal, then you will see rapid battery drain.

I have not had this issue with other phones. At least not this bad

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

Is this how it is for most people? My battery history always shows display as the number one battery consumer at 65-70% no matter how I use the phone.

My display is always first as well and it's between 60% and 70% all the time....my battery last all day with moderate to heavy use though so whatever lol

My screen is always the one thing that uses my battery the most but I still get a day out of my phone.

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.

25 min cost 27% battery

I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.
There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.
I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.
You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.
The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.
There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.
I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.
Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.
You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.
2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...
i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.
I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it
Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge

Battery is absolutely garbage

Am I the only one?
I upgraded to a native android device from a modded HTC HD2 to hopefully have a longer battery experience.
This battery is absolutely trash. My 2 year old HTC HD2 running Sense Android Non-Native ran at almost exactly the same.
I tested my HTC HD2 side by side with a close friend who has an Evo 4g.. Both Devices still being HORRIBLE in battery life performed almost IDENTICAL.
HTC HD2 is TWO YEARS old, why is it so close in performance to our device..
I love the phone in general, it's snappy (once i removed all bloatware).. Boots fast, runs nice.. i have very few complaints about it.
But how does an 1100 MaH battery run the SAME as an 1600 MaH battery?
I thought technology is supposed to improve, but my non native android phone ran almost the same as this one. Took longer to restart/boot up, but general speed is the same, larger screen size.. similar settings, and same battery life. Pisses me off frankly.
That's how I felt. hopefully we will get rom's or gingerbread on this phone soon that will improve battery life. And by gingerbread I mean the leak from Samsung for the i9000. I've been reading reviews and it seems like it Greatly improved battery while speeding up the phone a lot.

I have to disagree. I've owned may android phones including the evo. This phone has the best battery life in my opinion. I can easily make it almost all day with use without charging

Well like I said, i admittedly abuse the phone.. but I'm comparing to other phones getting equal abuse. It stands up about the same, better yes, but not by much.
If I'm barely using it however.. let's say, mainly just texting, yes it will last all day. But that never really happens.
I love how people admit that they "abuse" the phone all day and then complain that the battery life sucks. If you're going to use your phone that much, bring your usb cord. Or strap a battery pack to yourself and plug it in for "all day" use and abuse.
It's the screen. If you want the super amoled you have to put up with the battery.
What i don't understand is that why the Droid x which has similar specs to our phone can go up to 10 hours of continuous web browsing when our phone/vibrant can only go up to 4 according to tests. Is it because of the screen? If it is then that's just stupid.

It was horrible for me at first, but I then realized the system has to calibrate the battery first. I am getting about 16-20 hours with moderate usage now, which is better than the G2 I had before.
My g2 can go up to 28 hours with light texting and 2 hours of web browsing through wifi and 10 minutes of calls (manual syncs and low brightness also). Once I use the gps and browse through hspa, it's a different story. My sister has a SGS4G and her battery seems to drain faster than mine.
Oh, and if I keep my phone charged for a while after reaching the 100% mark, it stays at 100% even after 1 hour of heavy browsing and watching videos. I think we should all just assume that the battery meters are inaccurate.
I use juice defender and put my brightness setting on auto and I can literally go all day with "abusing" my phone.

let the phone die, to the maximus. meaning once it turns off, turn on again until it doesnt turn on anymore. Now fully charge it, once again when fully charged restart the phone and charge it to 100 again. then let it die again, and full charge. should be fine then
i bought a 3500mah extended battery for my phone. the battery is designed to work with vibrant. it really made my life a lot easier.
I noticed if I set the phone to GSM only, battery lasts almost twice as long. If I'm on auto select (WCDMA/GSM), it lasts from 7AM till about 4PM.
But then again, I don't have a very good 3G/4G reception (or 2G connection for that matter), so my phone is probably working extra hard to find signal all day long.

Same here.
I used to only have dark wallpapers and take all the other extra steps for my battery to make it through the work day, and as soon as i got home i had to charge it.
I'm now running fireflies live wallpaper, abusing the phone a little more then what i used to, and i still have battery to spare, not by the time i get home, but by the time i go to bed!!
i also have installed bali. seems to do well, as said its all about the brightness.
My problem with this phone is that wifi uses way too much battery. I have it to turn off when phone is asleep but i'll have the phone at 100% with wifi on. Put it on sleep. 4 hours later. battery is at 65%.
If i have wifi turned off. Battery will be at 98%.

Battery draining AGAIN

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.

Yes. Like the OP, I tried the solution of the person that is so called getting 20hr battery life under medium usage. Just doesn't seem feasible at all. And its really annoying to have to cut the data off completely to keep the phone from getting warm...

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.

What is your standby drain? I'm looking @ 3.5%/hr.

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.

Darn it...
Seems like I'm the only person with excessive battery drain...at 7%/hr....
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.

Battery life varies widely with same amount of usage

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
Sent from my HTC Sensation Z710e using XDA App
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.
