Over 48 hours on a single charge w/ BT and WiFi

To make a long story short, my mom and I both got G2x phones on launch day. Two weeks to the day after our purchase, her battery died and refused to boot even while plugged into the wall charger (which I now know can be fixed by simply pulling the battery). I was busy at work and couldn't help her, and since it was the last day to return the phone within the 14 day period, I just told her to go ahead and return the phone for a replacement.
Prior to her replacement, we had pretty similar battery lives. I used mine more during the day, but she kept Bluetooth and other services running because she was used to an EDGE-only iPhone 3G where she never had to turn Bluetooth off. Our phones lasted between 10 and 12 hours depending on usage. Not great, but not terrible either.
Since she swapped hers out, her battery life is insane. I've attached a screenshot that shows 70% battery life after almost 24 hours. She had Bluetooth running 24/7 (notice it has the exact same usage percentage as Cell Standby) and WiFi running for a good portion of the time (though WiFi slept while screen was off). She had 4G running the whole time. While I know people might balk at the bad LG battery drivers, after 48 hours, she still had 17% battery life left. I apologize for not taking a screenshot--I didn't think about it until later that day. Though if anyone wants me to, I'll take one the next time her phone gets that far along.
I should mention that this is with no optimization at all. She did fully discharge the battery the first time she used it and charged it completely afterward, but that's it. The phone was unrooted and running stock everything with no special tweaks.
I'm very much considering going back to T-Mobile and seeing if they will swap it out. While mine doesn't seem to have the bleeding or other issues that other people have described, if I can trade mine out for a replacement that will quadruple my battery life, why not?

Wow that's amazing. I personally feel the G2x has excellent battery life. It has been way better than other Android phones I've had in the past (except for the original myTouch, I would get like 3 days out of that thing).
I wonder if the crazy battery life from your mom's phone is from the phone itself or the battery. I doubt T-Mobile will switch out your phone passed the exchange period (I'm a Tmo employee) but if they have any return G2x phones in stock, they should be cool to switch the battery out with you. I'm interested to see if it is indeed the phone or the battery.

That's a good suggestion. I'll experiment by swapping batteries with her to determine if it's her phone or her battery. I am inclined to think it's something different with the phone, but we'll see!

this would REALLY suck if it's true... because I got mine at Radioshack.. and I really loathe going to that store... ugh.

I also have amazing battery life. I can go 12 hours at work and still have 80% left. Got mine from the store on launch day.
((LG Tegra G2x)) @FiberOpticRLD

Could you please post the manufactured date (back of the G2x Box) for the second phone? Saw some posts which said phones on or after 4/29 are really good without any of the previous issues.

Curious to see what the verdicts are. If we can get that kind battery life out of our phones, that'd be incredible!

Yesterday I pulled my phone off the charger at 8AM. Went all day. I leave Wifi and Bluetooth on. Made about an hour of phone calls. Occasional checking of a website here or there. Did not charge phone at night. when I went to bed around midnight it was at 25% or so. Did not put it on charger. This morning it was at about 20%.

Not to rain on your parade. But from your screenshot, it shows no voice calls at all and little to no display use. 24 hrs on a charge without every really using the phone isn't really an accomplishment. Now if she can get 24 hours on a charge and have actually used the phone at least moderately then that would be different. I'd like to see how long her battery lasts with actual use of the phone. That would be a more true indicator of the battery life.

I was going to state that... based on that... her screen was only on for a total of 30 minutes out of 1440 minutes... not a major accomplishment. These phones are meant to be used not just carried around like a flip phone from 2001.

Exactly! She could have pretty much accomplished the same thing by just leaving the phone turned off or just leaving it at home. Some of us would like to actually use our phones, not just have them around for decoration lol. Now if someone gets 24 hours on a single charge with actual use, then I'd love to see that thread as that would be useful information.

What's the date on your phone.

Love my G2x, But the battery is worst ever.

Have had my rooted stock rom g2x since day 1.
Love phone. I am comming from H2 customed. I thought it had worst battery I have ever had.
That was till the g2x. I hate running a task killer. But am about to do just that to see if I can get anymore battery,.
Its to the point where I fully charge phone and yesterday with only 12 minutes of talk. Maybe 20 minutes of Web use and some emails. Battery was yellow.
This is a joke right? My only thought is that by having my Gmail auto refresh every 10 minutes possibly that could be some cause. But I if not in my car to keep on charger phone last barely a day.

Sounds like you have a bad battery, I get great battery life with the phone
G2X & Nexus S

I get 13hrs on this battety with wifi on all day.

Did u calibrate?
Sent from my LG-P999 using XDA Premium App

do u really think that is the standard performance of the G2x battery or is it more likely you got a bad unit ? Come on now people, stop posting this crap and just exchange your phone when you only get an hour of battery life. Why start a freaking thread ? You could have used that time to go exchange your phone.

Totally true.
For those of you with problems, your phone is still new, it will be replaced either under buyer's remorse (15-20 days) or directly through tmobile after that period.
Just get a new phone and be done with it.
My first hot potato of a phone would get good battery life, until it cooked itself alive. My second phone was on for over 27 hours and was still at 50%. I'm still surprised.

First off guys. I am not a newbie to XDA or phones. No its not a bad battery.
Remember I am the Costco Manager so I can exchange phone as much as I want for 90 days.
This is my third as I wanted a perfect screen.
I have had this problem with all 3. So the battery is fine.
I use batt apk and I show about 5%loss per half hour after taking off charge
There is no way this is normal. Now I do have lots of apps. But I have froze some in Titanium. However I can blow out this charge in an hour with web use.]
No I did not calibrate. Did not read that till after. However I did charge initially correct.
My HD2 would gobble batterys. But this phone while I love it. Is not a great everyday use phone if not able to be on a charger during day.

Huh.. some people are getting awesome battery time. When it first came out, people were having success with doing factory reset on their phone. Idk.. I personally didn't buy it.. but they swore it worked. Give it a try.

So what you're saying then, is those of us with good battery life are the ones with the bad batteries? You really didn't think this through, did you?
I find my battery life was OK on the stock ROM. Nothing I'd get excited about, but I'd gotten used to insanely poor battery life running CM7 on my vibrant. Since I flashed the GB leak (no wipe, fixed permissions, erased battery stats) I'm seeing 18+ hrs with moderate usage.

gingerbread in general gets good battery life, cm7 for galaxy has problems due to samsung not following the google standards, those guys are basically shooting in the dark with that project, yet they have made huge improvments. recently people report decent to improved battery life on the latest builds.
to the op, what are your sync options? i find facebook sync and facebook contact sync are big culprits. also i only use google contact sync to get my contact list initially then turn it off. also if you have your gmail on the stock email app and the gmail app it can increase useage, if you prefer the email app id turn off google sync all together, if you like the gmail app id turn off fetch on the email app.
another culprit is weather apps using the location service, for me beautiful widgets is a battery hog on a vibrant rom but not on a captivate rom so results can vary from phone to phone.
and last of all i dont agree with calibration proceedures, i get some funky results with them, i just delete batstats and then charge to full. i find it takes 3 day minimum to get a good calibration, 5 days is sometimes needed.

I get very good battery life with mine and have been since day one. It lasts almost twice as long as my Vibrant and N1 did.

I use juice defender to turn on/off my data for me when its not being used and the screen is off. It seems to work less than on vibrant.
I'm running stock rom and my battery life varies TREMENDOUSLY from when I'm at work and seldomly using it to when I'm home surfing the web on it ( tablets too far from couch I'm surprised I got the cookies )

I was getting really bad battery life when I first got the phone (about 7hrs ) I ended up finding out that the touch led notification app was the culprit so I deleted it and also calibrated my battery and now my phone last all day easily and that with me playing guerrilla bob and the samurai game at work for like 2 hours lol
I recommend you download the where's my Droid power app from the market and see what's killing your battery

Also keep in mind that it could be a certain app draining your battery. I downloaded the NFL apparently for draft day and even after exiting the app it took my battery down 15% in a matter of 10 minutes. Not to mention it had my battery's and CPU running super hot. On average I get about 12 hours out of a full charge with moderate to heavy usage.

My last charge i got 36 hours of light use so I dont know what everyone's problem is lol

No wonder your a newbie and no listed thanks. What an asswade comment.
NO!!!!!!!!! What I am saying is that is has to be an internal issue with either synch times or possibly an APP be it internal or external that is causing MANY of us to have terrible battery times vs. others with good. Not saying anthing negative about those who are functioning ok.
I have been rooting and modding for 2 years. This is the worst battery usage yet. My Galaxy S 4g. Could last with same synch times and apps for 18 hours.
Now for those others who have there head inserted other then in there behind.
Okay ran some tests today,
1. Charged phone to 100percent.
2. Left everything the way it has been and no adjustments.
Battery at 84 Percent sitting tableside no text, app, wed or voice use after 2 hours. After 4 hours at 64 percent. After 6 hours at 51 percent. After 8 hours at 39 percent. This is with no usage. This is terrible.
Okay, Now have done following based on others test here and other forums.
1. Loaded Setcpu and made profile for sleep using stock 216 usage.
2. reluctently loaded Taskmanager Pro and killed all but needed apps.
3. Loaded Battery calibration app and after charge calibrated phone.
Left my email synch at every 10 minute as its needed for work.
We will see if this brings better test times now and report back.
What may be my culprit from studying this and other forums is I am in Seattle. We are Tmobiles home office corp and full test market for 4g and every change before rest of USA. I get full 4g at all times. In fact my speed tests are off the board. ave of 12 down 1.3 up speeds.
From what I am finding out, those of us in best 4g coverage (and Seattle is listed best) are finding much more drain on battery in standby and in use.
So my theory is that with this phone and its dual proccesor and my 4g, this is why myself and others in like markets are seeing much faster drain then others. Some dispute this possibility. however other experts say its fact.
Will report back findings tomorrow.
Thanks.

May be some of my issue vs. others.
I do have sync on for FB and Google mail 2 accounts. and I use Fancy Widgets for my Weather and news feeds. However I also used these on my HD2 a known battery hog running cm7 and it had even better life then the phone. I run them on my other Galaxy s 4g as well and it has awesome battery life.
But I will freeze these in my next test after running this test.

those are shocking results man... I dont know what to tell you... If I literally dont touch my phone for 6 hours i will drain no more than 10% of my battery, closer to around 6 or 7% based on my battery monitor widget...
I pulled the phone off at 6 this morning and didnt touch it until 12 and I was at 92%... Chelsea got ****ing spanked this morning and I got a barrage of **** talk text messages that I did not want to deal with haha so my phone wen untouched for a good 6 hours...
I will say though, when I first got the phone my battery life was pretty wonky... first drain was great, second one was mediocre, the third and fourth ones were horrible, drained in 6 hours flat of light-moderate use... I did a factory reset at this point to try and change things up... Calibrated once after that and I have run it up and down to get a good read and I have not looked back since, like i said i can get 20-30 hours of moderate to light use no problem at all!

Great battery on my g2x
I had battery problems with my G2x, only lasted about 7-8 hours on moderate use and cell stabd by was like 50% of battery use.
After i installed the leaked official Gingerbread ROM is like a new phone, ofter 16 hours of use i still had 43% last night. In idle mode it uses about 1% in 2 hours.
I think the battery probles come from Froyo not getting along with the dual core processor.
This phone is awesome!

Iceshark, you're not crazy. This is the same exact battery drain I get not even touching the damn phone! This is my second phone in less than 2 weeks, the first had the same results, both brand new.
Today I unplugged my phone at 12:45 pm, gave my mom a call for mothers day (less than 2 min talk time) Got to work and browsed web for maybe 5 minutes then clocked in at 2 pm. Took a 15 min break at 4pm battery was down to 80% (did some web browsing for 5 min). Took my 30 min lunch at 6pm (battery was down to about 60% (did some browsing for about 15 min). Took my last break at 8pm, and battery was down to 30%. I clocked out at 10:30 and I only had 20% battery left. The only timeI touched the phone was on my breaks, the rest of the time my phone was in my pocket. I had juicedefender running on balanced.
It's now 12:01am and I only have 14% battery left, that's not even 12 hours yet, and I only used the phone and it's features for less than an hour, all the other drain was sitting in my pocket. This is unacceptable. And I'm starting to think all the other people who claim to have great battery life are exaggerating or lying through their teeth.
Although I did a test yesterday using auto airplane mode, which automatically enables airplane mode when the screen shuts off, disabling any data, and then it turns data back on when you unlock the screen this helped very much with battery draining and at the end of an 8 hour work shift I still had 70% battery, but without data you can't receive calls, which sucks.
This battery drainage or bleed while the handset is not even being used needs to be fixed. And isn't it false advertising since the G2x specs indicate standby time is 400 hours?

[Q] i9020a AT&T/Best Buy Version Advice

Hello All,
Hoping to get some advice. I bought the official i9020a from best buy yesterday (on launch day) seems to be a great phone but I have a few questions and problems.
I unlocked the bootloader but did not root it yet
The biggest issue is battery life. Its terrible (like nexus one before applying the wifi setting trick after 2.3.4 terrible). this NS loses almost 10% of its battery power per hour on standby.
While on standby I have the following running
-wifi turned on
-3 push gmail accounts
Also I noticed that the hotspot doesn't work. when i turn it on it briefly shows 3G and the signal strength bars in green but then the 3G icon goes away and the signal bars turn white, my tablet and laptop can connect but no internet from connected devices and the phone browser itself - just page's not found
my baseband is: i9020aucke1
kernel version: 2.6.35.7-ge382d80
adroid-build 'at' apa28 #1
Build Number: GTJ61
Any advice on the above would be great, I can easily return it but would rather keep it.
Anyone else buy the official Best Buy version and having issues?
Also Anyone know if this phone is locked to AT&T? I don't have handy access to a t-mobile sim card.
Thanks in advance!

Flash new rom. I am sure ATT has some tethering lock on the build. That should be expected.

10% / hr is unbelievably bad (assuming the display isn't constantly on). What's consuming the battery in the battery stats?
Thus far no subsidized Nexus device has ever been sold sim locked (The Vodafone Nexus One, T-Mobile N1 and NS and the various Canadian Nexus devices). I'd be surprised if it were sim locked.

Thanks everyone for the tips. After my original post and now I finished the root and installed cm7.
Cm7 took care of the hotspot issue. Battery life is still pretty dismal in standby. Ill do a test tonight and leave it unplugged all night and post what used the battery the most in the morning.
Thanks again

no man, something is really wrong with your device. My phone loses ~1% in each 4hrs in stand-by (during the night).... I can easily stay 2 days with one single charge (with light use) and with everything ON!
edit: oh, and btw, you won't find better battery in any rom out there. stock rom with stock kernel is the best so far (regarding battery life)... i really tried every single combo and it's the main reason i'm back to stock after so many time (with several devices) using cyanogen. with cm7 i use to lose 1~2% per hour in stand-by!
edit2: you should make some complete battery cycles. Battery life in the first week is not really great, but not that bad anyway!

I think there is something pretty wrong with it
a little over 4 hours last night unplugged in standby/locked
start power: 75%
end power: 35%
most used
display 64%
android system 6%
cell standby 6%
Everything else was system stuff at 1%
Display seems to be the culprit in standby.
Hardware? If so I can easily exchange the phone
Thanks again for the advice

I bought the T-Mobile version back in April. I found that my battery life on day 10 was about TWICE what it was on days 1, 2, 3.... I guess the battery adjusted as it got used some.
I suggest you give it two weeks and then note your battery life again.

I have seen the "battery gets better over time" statements quite a bit on XDA and other forums. I'll give it a week or two and some cycles.
I have to say the "it gets better" is not something i have ever encountered on any smartphone or dumb phone i have ever had though?
Anyone also getting really really slow charging during the 1st week?

If you previously had a non samsung device it charges *slow* even on a 1A charger. No way around that.

thank you! yes - i should have probably mentioned that this is my 1st samsung smartphone.

Yes, it charges really slow and it wont be better. Takes about 3,5hrs to a complete charge.
Battery really gets better after 2 weeks, but even in day 1, never was so bad as you described.

Fixed!
Ended up returning to best buy swapping the phone. the new unit straight away showed normal discharge during stand by and normal battery when in use.
In the end a bad phone.
Thanks to all for the above responses!

ya you definitely had a bad dud...i was lucky in enough to get a good "dud". with approx. of 3 hours of display on, background syncing, and other moderately intensive tasks i was at a point where i was going on 1 day 12 hours 16 mins and still had 40% of battery left.

Battery Life, Oh?

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.

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.

Oh! Makes sense..
But 2 hours with screen and dead in 6 hours? I'm glad I have a G2x then. Cause I get 3 hours and like between 13 and 16 hours.

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.

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.

Am I the only one with poor battery life?

I can't get through half the day.

could you be more specific as to what you do on your phone? is your phone the international version or the USA T-mobile version.
Sent from my Transformer TF101 using xda premium

Tmobile, stock everything and I had the battery issue on my first HOS. I just got my replacement and Im running the same apps, same calls, same eveything as the first phone but i get a significant more battery life. The battery on the replacement HOS lasted me the entire day, but I still carry a charger around just incase.

Superbattery?
My TMo One S battery life recently went through the roof for some reason. I can only attribute it to one of the following or perhaps luck:
I've been charging it at end of day regardless of charge but I finally let the charge get below 25% -- I think it got to 15%. Then I powered it down and let it charge 12 hours overnight.
I disabled all Facebook related apps.
Other than that I can't recall anything I did recently that might account for my new super battery. But I'm at 1d 4h 25m on battery -- most of that on WiFi granted -- and still have 42% juice. I'll take it!

I always have my charger because I'm a twitter whore. I recommend disabling any bloat ware or duplicate app like Facebook For HTC or Twitter For HTC. And make sure you change settings for each app you use and don't use.

Anyone use Juicedefender? My battery is excellent but if it can be improved then even better..

I'm using my phone very much, with Facebook and games and such, and I still get through the day without hesitate! I think it's wonderful

my battery life was poor on stock rom aswell. went trough a day only. had to charge every day. but now with noble v3 rom and being tiny bit more careful with use i have battery for 2 days

Battery life on this phone is better than most and I give it that. The only problem I have is the quick drop from 100% to 92% in a hour from little to light usage.

I'm on stock Tmo US and have been getting amazing battery life. I took it off the charger when I left for work at 7:30am and I'm at 75% at 8:50pm.
That's with quite a bit of texting, pics taken at work, and 45 minutes of web browsing while I was on lunch. Granted, I don't do Facebook, so that may help.
This is the first phone I've been lazy about rooting because it's worked so well so far.

I get decent battery life as well, but how do you manage only a 25% drop with over 12 hours of on time whic included a bunch of texting which keeps the screen on while u text and 45 min of browsing. Seems too good

I just got my One S less than a week ago. Love ICS. Battery life has been about 10 to 12 hours with medium amount of use. Facebook is disabled. I'm using active sync to sync to my exchange server and push frequency. (that continually goes out but that's for a different thread I guess).
I charge over night as I've done with my Dinc2, original Dinc, and all flavors of blackberry.
Last night I used a digital clock app while it was charging and in the morning at 8:30 where I unplugged, it had 100%. It's now just past 11 in the morning and with email, one short phone call and some light surfing, I'm already down to 62%.
I have noticed the phone is hot which means it's working hard to do something.
I have WiFi off and GPS off as well as location services. Should I return it for a new handset? Should I just go back to Verizon and get an iPhone?? Ugh.

What's your "screen on" time? Have you changed any connectivity settings, that may have increased your battery life a lot?

If the phone is hot then something is running in the background you should probably figure out what that is and disable it before you do anything. Now with exchange servers set up on your phone they do tend to eat some battery. That's universal though. Sounds like to do have a rogue app though. As for me this past Monday I took the phone off the charger at 430am and didn't have to return it to the charger til 11pm mostly because I was going to bed. I watched netflix, text, phone calls, Web surfed.... Love this device.

To you and the other person that asked, I think it really has to do with cell signal strength.
I posted those numbers after coming home from work where I have awesome cell coverage.
Today I've been home all day, and even though I'm on WiFi all day, my cell signal is horrible here. WiFi or not, it's still searching for a signal constantly so I've lost 30% in 6 hours with moderate use.
Now, as I said before, I don't use facebook or friendstream, but I think a lot of it is the radio constantly searching for a better signal.

I also think that either bad signal or just 3G takes a lot of battery.
I switched to 2G only just as an experiment, where I get a good signal almost constantly. This extended my battery life quite a lot. Where I usually had 10-20% left after a full day, I had 50% left with only 2G. I have also been using WiFi where available.
Can this be a software bug since there is such a big difference? I've noticed before that phone calls suck a lot of juice...

2G is known to use much less battery life in every phone you check it.
Take a look at GSMarena on phone specifications in the bottom and you'll see the great difference.
BTW, looking on the battery test GSMArena did for the One S, it's quite in good place for the 3G calling and Video playback but uses a lot of battery on WEB browsing, see here
Might be that we the ones with low battery are more surfing than the others...

I get about 24 hours.
2 hour screen use. No FB or twitter, only gmail sync
Some text, 5mins of calls, <2% no signal
When idle i get battery drain of <10mA using:
http://www.3c71.com
Battery Monitor Widget. Logging current consumption is the only way to get to the bottom of the problem.
I'm talking with the author to get the kinks worked out of the One S logging.
*but* for some reasons something is keeping the phone awake at times. current drain is then 70-80mA constant. Not been able to find the culprit, but a reboot helps.
Hopefully this was useful.

I had the same issue-downloaded 2x battery from the market and it is much better. ( I have syncing with twitter, fb, gmail, mobile life all enabled)
I could barely get through the day. Seems the phone does a lot when syncing etc and this stops that, or at least limits it to the interval of your choice. every 10 I believe with the free version.
Try it-I am sure it will help. (I also turn the brightness down as I am mostly indoors-and put it on auto outside-but that is just me)

Actually, due to the fact that every time I check the usage of battery screen is in top place (with Auto brightness all the time) and the fact I'm syncing with FB, Gmail, Exchange server and more, I guess the best thing to do is to lower Screen brightness...
