What kind of battery life are you getting?

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

Are you on wifi or 3g? Brightness? Screen timeout? I have an N1 and the battery life is pretty poor so I'm just curious apples to apples in terms of what else you have turned on.

I leave 3g on but i always left it on on the vibrant as well, brightness is at 20%, screen times out within a couple seconds
wifi, gps and bluetooth off

I get great battery life. Then again I am coming from a Vibrant, my battery was horrible on that device. I take it off the charger at around 8 am and by 6 pm I still have 50%

ever thought about turning off 4G? You don't alway have to have it on.

I get around 12-15 hours with heavy usage. My G2 usually gets 15-24 hours.

I saw this article the other day. I was thinking about trying it tomorrow.

Don't bother with that battery charger hack, it's not going to do anything but waste your time...
I just installed SetCPU on my phone just for fun and have found that it recognizes a few lower clock cycles...I added a profile to lower the CPU when the screen is off otherwise at 1024-245 On Demand and I'm still plugging away at 20% battery when I would normaly be on the charger by now...could be a fluke, but so far so good...I'll keep this for a few days to see how it does.

oh, one other note, my battery life has continued to improve with every charge...the first few days I couldn't get through a full day and now I have battrey to spare...just had to get it conditioned with a few charges I guess.

I let the phone completely die last night and then charged it and at midnight I unplugged it. At 8:30 this morning when I left for work it was at 94% which was great but from 8:30 until now it has dropped to 83% and ive had one 3 min phone call and deleted some text messages, no browsing web, no listening to music, nothing. It seems like the phone will go through the 100-95% slowly but after that its in a marathon to get to 0%

I don't know how you guys are getting so many hours daily on heavy use. I get 7-8 hours on heavy texting, some web browsing and about an hour plus on the phone almost every night. 9 hours would stretch it and it would be on 10%.
I have my brightness all the way down and all the way down is just 11. Screen times out in 2 minutes and I have power saving on. I did the battery thing 3 times where I would let it go down to less then 14% or so then charge it fully without taking it off charge. Hopefully it improves as days go by, I'm just tired of carrying my charger to work.

Down to 69% now at 11:15, have made no phone calls or texts since then, have just downloaded opera mobile but havent even played with it...lol this is riduculous

I can recommend that you guys take a look at what might be pinging the CPU. Watchdog (Lite) is great for this task. You can have it alert you when an app exceeds a preset threshold for CPU usage. Some apps just go rogue on you like Palin from time to time.
I've also noticed that there's wide variability in terms of how apps go into either idle or background states. Some apps will go into idle only if you hit the back key to go back to the home screen and will enter a background state (more active) if you hit the home instead. I've also noticed that the free, ad-supported apps require more CPU time. That's right. Hitting Google's ad servers, at least for some apps, and scrolling those ads, requires more CPU time than other apps, which do the same. I don't know whether to fault the devs in this case when coding for the ad retrievals or not. Just some things to consider.

I just got mine. I came from a Blackberry 8900 and an old 2g iPhone. Battery life on both of those was significantly better. I could talk for 8 hours a day on the BB and it would last until midnight-1am or so. The iPhone would only last until 10pm.
Using the MT4G, my battery life is REALLY bad compared to these other two devices. I can get about 5.5 hours of continuous talk time, tested yesterday on a conference call for work. But even with only calling for about an hour and some basic email checking, I can't go past 6pm without putting the phone on the charger.
Wifi is off, screen at 50%. Someone please make a big fat 2800mah battery for this thing. I use this thing for work, and I make over 4000 mins a month of phone calls. It's really annoying to have to plug it in whenever I have the chance.

im getting roughly about 15-17 hours and im using it (camera, blogging, facebook uploading)
this destroys the EVO i had

Heavy usage, I'll get around there, 7-8 hours...regular usage gets me around 20 hours..I'm using setcpu w/ profiles..

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

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

I think I only brought my G2 into work a couple times so cant really comment on that but in the 3 months ive owned the vibrant, if i used the phone a lot during the day....i mean play games, texts, web, etc..id leave with percentage in the 50s, normally in the 70s, at 4 today i was in the 30s with the mytouch with barely doing anything, since i want it to last until the night i just threw it on the charger. it shows I have full signal (4th floor by window)

My wife just got an mt4g (I have a nexus one). I've noticed that her battery life seems to be just over half what mine is, and I actually use mine more!
When I looked at her Battery Usage display, Android OS was near the top with almost 2h CPU time after being unplugged for 6h. For comparison, on my nexus one, CPU time for Android OS is 4m13s after almost 8h.
Any good way to break that number down more and find out the source of this crazy battery usage?

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?

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.

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.

[REF] Batterylife results of i727 Skyrocket

I know it has only been out for a little more than a day, but curious on what sort of battery life people are seeing on the Skyrocket.
Thanks

Just got mine about an hour ago so I will report back, what I can say that LTE is amazing.

I had it since yesterday... however.. I had a wakelock issue.. so mine never went to deep sleep till I found the culprit..
but so far so good. it's very similar to the OGSGS2 (I owned for 28 days)

Not just on LTE. I'm constantly getting 7-10 mbps on hspa+. Never ever seen that speed on any of the so call 4g phones on at&t till now. I did a speed test at 3 in the after noon where I usually was getting 1.5 - 3.0 on my ogsg2.

They are reporting a full day use with no problems.
"The battery is larger than the one on the SGSII by a good margin, the better to supply that power-hungry LTE radio. Though most of the time I was on HSPA+, the phone lasted all day and through an idle night with 30% battery remaining, a solid showing."
Another review: http://www.phonedog.com/2011/11/07/samsung-galaxy-s-ii-skyrocket-first-impressions/
"Skyrocket brings a rather large 1,850 mAh battery to the table, and it shows. If you're a road warrior or someone who's away from an outlet for an extended period of time, this may be the device for you. With moderate use including some calling, text messaging, browsing the web, downloading apps, and running Quadrant Standard tests, I was able to make it through the day and well into the evening before a recharge was needed. On a related note, I've chided Samsung devices in the past for taking too long to charge, and that seems to have been improved upon. "
(woot 100th post)

have to say it has Great Battery life.....probably the best on a phone that i have had so far. again its still new. but i get a full day of use and still have 30-40 percent done by the time i hit the pillow.
im impressed especially since its an LTE phone and everyone kept yelling----IT WILL BE A BATTERY HOG.
nope

my wakelock problem was with FriendCaster Pro. After stopping the app a few times it release wakelock and it's properly going to deep sleep
As for battery. I finally got a "full" day of use. from 10am to 11pm I have about 19% left. That included GPS use for about 15mins, watched a movie on NetFlix (A Knight's Tale) and about an hour worth of 3-way calling and some texting.
I have Background and Auto Sync on with K9 email polling every hour for one of my POP3 + and 2 IMAP account is pushed.
Polling calendar using Calengoo every 3 hours

Honeslty no issues at all. I use my phone for txt calls web all day for work had no issues at all. I don't have Lte in my area but occasionally travel to areas that do. No pixel issues either, yea its bigger but nothing noticeable.

I wish I could say the same. 12 hours later my phone is down to 10% from full charge.
Guess I will pay AT&T a visit and see if they would replace the battery for me.

today... i've been on battery for 13 hours, 1.5 hours with the screen on, mainly surfing around using LTE, as well some texting. also downloaded a few apps.
37% remaining.
i think that's pretty good.

I've been unplugged for a little over 18 hours as of now, (about 7 of that was idle while I was asleep) and I am at 34% right now. I've used the phone quite a bit today and I would say that battery life seems to be about the same as the original GSII.

Yea mine is no different from the i777 s2. I did however root it n disable some junk. I'm sure that had something to do wit it.
Sent from my SAMSUNG-SGH-I727 using xda premium

Yes quite respectable, granted my iPhone runs forever on a charge but it's pretty good. Also I had read that the phone will turn off the LTE radio if it's not in a LTE area, opposed to other networks.

Hope these skyrocket threads can be moved to their correct destinations...

can u post some shots of battery use I'm getting only about 6hrs at most changed battery already think it might b the phone want to go show att rep so I can replace phone with no restocking fee

This is from my first day with the phone, you can see it was idle for the first 7 or so hours while I was asleep, then what I would consider pretty heavy use, being my first day with the phone.

This is what mine looks like after 2 hrs
why do I think my screen is at 51 how high is your brightness? Just figured out that automatic screen brightness is set to certain brightness turned down maybe will help me get more battery life

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.
Sent from the (problematic?) One S.

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...
