Hi!
How long does your Mozart work.
My settings: WiFi & BT are off / Exchange sync is permanent.
Around 30 mins calling time a day.
Battery is empty during the afternoon. It simply does not "survive the day" and has to be recharded. Is my device not ok, or do you have the same experience?

Are you on telstra network perhaps?
I read something on the internet about a bug in the Exchange service, it reestablishes the connection every minute, so thats why you battery is empty so fast. (probably)
HTC is working on the problem. but if you are on a Telstra network there is a workaround http://blog.walshie.me/2010/11/15/htc-mozart-telstrabattery-issues-solved/
Hope this helps
I was not too pleased about the battery myself, but it was never as bad as what you're reporting!
I've always had Wifi turned on and use Exchange email... and have been continuously using the media player or an app or game now and then... and it lasts me a full day... There was once or twice when i had been continuously at it that it had 20% left by evening...
I posted about it on the forums too and someone said it'll automatically adjust itself... i was a bit skeptical, but today it still has 60% battery left and it is 12:15 AM now...! (though i did have Wifi turned off for the most part today)
Hello everyone
I have the htc mozart one month offered by the girlfriend. I used the mobile phone several times and even with wifi and bluetooth on and always lasted one day (24h) without problems. yesterday charged at 24h and at 15h had no battery. had not even turned on wifi or bluetooth. since then the battery does not last anything I do not know what happened but its not and nomal. Somebody now something about? This its really a joke but I know that the battery lasts well over

were you in an area with poor cell reception? if yes, that would affect the battery because the phone is constantly working to maintain a signal. i'm using an 1800 mAh battery from Mugen and it's easily lasting 32+ hours with 1 Push Exchange account, BT/Wifi off, 2 POP accounts (1 hour retrieval times) and about 40-80 minutes of calls when i'm in an area with a strong signal. i spent two weeks at a client site where i could barely get 1 Bar (and most often had "No Service) and the same battery would be depleted in about 18 hours. when working in an area with great cell reception, battery life is great for my use. on 2 occasions i forgot to charge the phone overnight and had about 15% battery left when i woke the next morning. in case you're wondering, i'm using the HTC TestTool - Battery Tool (v1.20.0.0) to determine battery percentage. you can find in in the WP7 forums.
I'm using the phone as I have always used but something happened that makes the battery last while. without stirring overnight stays with half in morning

That the point you living in area where the cell phone reception is really bad!! It's same for me when I go to my Island in carraibe !!But where I living Paris and London I can keep the battry 100% at 7h in the morning till late in evening around 2h at 20%; Using all day Wifi, TV, Game... So the issue about battery is not the phone but carrier issue.
Because when I take a "Metro" or "Tube" where the reception are really bad my battery drainning fast....
For me it last for a day, since i don use 3g n wifi, i use followin settings.
3g turned off
wifi turned off
Always try to close the running apps using the back key.
everynite i switch my phone to low brightness, so that i don need much time in charging my phone in the morning b4 i leave to work.
with every settings turned on the battery last for 15-17 hours.
hope they fix the battery issue in the comming update.
With heavy usage 9-10 hours battery life for me.3g,4 e-mail account.One is push,the others checking every 15 minutes(almost getting 150 e-mails every day).1 hour talk time,Web browsing over 3G,listening music 30-45 mins,playing games 15 mins.(Brighness medium,location service all on)
using dark back grounds will help save power, but everyone nows that dont they.
Except it won't help with Mozart. It only works for AMOLED displays, Mozart has an LCD.
it has at least awesome standby time...
the red light once began to flash when i went to sleep.
when i got up around 9-10h later the phone was still on.
only bluetooth was off...
even more standby power, im back to report:
3+ DAY STANDBY!
i charged my phone friday 02-11-2011
untill today (tuesday) it still lasted,
same-time as last-charge 02-15-2011
thats incredible 4 days...
WLAN was OFF the most time
3G on
only did around 4-7 2min calls
didnt play much with it,
only quickly checking for news in market from time to time
had 2 reboots because of that
and did around 5 pictures.
i think its pretty awesome times...
yeah with heavy usage its only 1 day
but still its a phone and its standby is great
There's no surprise that the phone lasts long when you don't do anything with it.
As far as I can see, the battery annihilating combination is browsing the web via 3G. Guess IE was optimized for speed to impress with responsiveness. This probably won't change much until IE9 comes (which may or may not help). The power-hungry screens are a universal problem on all current HTC devices, with WP7 and Android equally, so this won't change.
The real killer is WI-FI, i upgraded to the MUGUN 1800MiH Battery, and im not looking back, it lasts way more than 50% longer than the standard battery did.
for £28 with free delivery, you'd be silly not to buy it.
also, as an aside, the Battery arrived within 4 days from HONGKONG, which is great because it advertised that the battery would have a 10 - 15 day shipping time.
Okay... what if
had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@
Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that
In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!!
the first two days when i got my mozart it died on me due to low battery. but when i upgraded it to nodo(i think), the battery is longer now. but i will check some more.
my battery usually lasts 24 hours. But when I open htc weather, starts to pick up GPS signal if I leave soon have a very abnormal wear of the battery.
I tried with other Porgram gps and the same happens, the battery does not last 10h
Anyone with a telecom New Zealand (9300T) can you check your cellstandby for battery
It is using more than the screen is.
yesterday phone was at 30% with only 2 hours screen on.
Cellstandby used 67%
Can anyone else confirm that they are having the same problem on the S3 or is it the telecom nz firmware doing it.
If so I will root and flash another providers firmware
I have the phone in dubai and the cell standby has been very high since day 1.

This is NOT an issue. The numbers have to equal 100% as its a measure of what's been happening since your last charge so if its doing nothing then cellstandby gets the highest percentage. ITS NOT A BUG.

That means that it has used 42% out of the 37% that have been used during those 8,5 hours. 42% out of 37% = 15,5%
Hence, cell standby, only used 15,5% of battery during those 8,5 hours.
15,5/8,5 = 1,8 % an hour.
Not an issue, as stated previously.

Go away with your baboon logic. There's people posting 5h screentime battery statistics with cell standby having almost equal percentage as the screen. Either it is a very bad reporting error, which I doubt because people are reporting bad standby battery life, or there is something wrong with the modem firmware which has already happened on other devices.
It is an obvious issue, and please go install Badass Battery Monitor or something else to view the absolute µAh draw so we can stop the lame excuses about how things need to sum up to 100 and other flawed logics.

And since when the hell is 1.8%/h pure modem draw been acceptable? The Galaxy S2 with the predecessor of the exactly same modem hardware is getting 0.5%/h total standby draw usually.
I'm on Vodafone nz. With pretty heavy use the figures were just over 7 hours screen time out of 12 total and cell standby stood at 14%

It drained over 8% of my battery in 5 hours today. (Battery at 78% now in 5 hours - was 100% this morning)
Having this problem as well. Phone wont last me throughout the day with minimal use and you can feel it hot when placing it in my bag.
I wont start talking about the % use of cell vs screen. But when the battery lasts 10 hours with only 30min of screen use throughout the day, then there's a problem !!
I had this problem with Galaxy S. Changed modem firmware seemed to help a bit but still isnt as long as my previous phones.

Seems something is wrong with your phone. Mine has had medium use for over 20 hours and i have 36% battery left.
Mine is at 61% now and it's has 09:30 hours use. My screen has been on for 1:30 hours so quite heavy use.
The weird thing is:
My phone radio started out with 55% power use the first 2 hours and dropped to 30% power use and is still dropping. No idea why tbh. I didn't use my phone more or let my screen on for more time..
My screen is still around 50%
My app use is 21% now. (with sygic taking up 10% while the app is not even on)
Hey new here....
12 hours with absolutely no usage besides alarm and went from 100 -> 13% battery.
Will get the battery app mentioned previously and see what that reports.

Long story short, I bought the HTC EVO 4G LTE (The US carrier, Sprint's variant on the HTC One X). Sprint has a 14 day return policy. For me, it ends on Saturday. I'm considering the GSIII.
But the most important thing is, how's the battery life? How well does it do when you're using 3G?
But most importantly, how badly does heavy texting (as in, new text messages every minute for about 4 hours) effect the battery?
I text all day long from 8am to 8pm (medical school ) and WhatsApp/xda app. Lasts the whole day. But I run in edgge not 3g

I'm in the same boat as you. I love the screen on the Evo but the battery life and multitasking issues have got me strongly considering the GS3.
I've been haunting the forums here and it seems like people are getting amazing battery life. There are many people posting screenshots of 5-6 hours screen on time. I've even seen some that exceed that. By contrast my Evo has been running 3.5-4 hours. That's less than what I was getting on my OG Evo (of course it was rooted and running a custom ROM/kernel ).
I just went and spoke with my Sprint representative about what I'd need to do to make the exchange. I'm 95% sure I'm going to pull the trigger on this switcharoo.
Best of luck in your decision!
Was quite bad at first, but something changed.. now it's awesome. 15 hours and 70% left. Moderate usage and 3G/HSPA+
Do you know what changed to your phone?? 15 hours with 70% left is amazing How often were you using the phone ?
The battery life is fantastic. Just turn off the crappy S-Voice features that wait for your voice input.
How long is the screen-on time? I seriously doubt texting requires heavy usage of the radio. So, the screen is obviously going to be the biggest drain on the battery.
Battery life is misleading straight out of the box. The starting charge is completely out of sync with the phone.
I had to run my battery dry and full charge it to calibrate the battery properly. Once I did, then battery% values balanced out and phone has been a dream ever since.

it was with moderate usage (lots of texts, a few calls, a bit of game play, but not much) and I turned on power saving when I wasn't using the phone(don't know whether this actually does anything when the phone is asleep anyway... and off when I was). Don't have s-voice running (disabled it manage applications menu), turned off motion as I never used it, turned off NFC, S-Beam and Wifi-Direct (some of which were turned on by default! and this is SUCH a battery killer)...
Basically turned off everything that I don't use.. and saved a hell of a lot of juice.

I think the longest I got was almost 30 hours, thats using whatsapp, heywire, facebook and skype here and there and tinkering around in the marketplace. I had most of the settings switched off as you did...just noticed I had nfc on...switched that off too now. I just joined the android community, switched over from my Iphone this week when I got the SG3 so im still getting used to it
I think because of the quad procesor the 2.100mah wasent enough.It is very good!All day from the morning with 100% with full brightness,wifi,download gameloft games,gps, and i had 20% the next morning!!With custom roms will improved more!!

I managed to get the 99% battery issue sorted!
I have used he external battery charger on my 2nd battery and today I thought of trying the new battery for the first time to get some cycles on. Guess what?
The samsung desktop charger powers the battery all the way. I have now 100% on the new one and it dropped as I'm typing now after a good 5minutes of operation, unlike it used to do which was immediatelly after unplugging the charger from the phone.
So I presume that goes with the original assumption that the phone does not overcharge the battery for lifespan purposes. Why would the desktop charger would though?

I'm now giving this method a try.
Charging up my spare battery with the Samsung desk stand/charger.
---------- Post added at 09:48 AM ---------- Previous post was at 08:56 AM ----------
Interesting.
I've found the same as above with the 99% issue.
Having charged my spare battery up in the phone, I've then put it in the external charger, which after another 10-15 minutes charge, the LED turned from red to green.
Having now put that battery back into the phone, the battery is still on 100% after being unplugged for more than 30 mins.
Usually, the battery would have dropped to either 99% or 98% as soon as it was unplugged.
So, it would seem that the desktop charger does charge the battery up to the full capacity, while the phone itself, seems to stop at 97-98%. Weird.

I am also a new S3 user (migrated from an Iphone), and have been plagued with the battery issue. However, I have come to realize that you can't have everything with charging twice a day. You need to turn off the GPS, and set the WIFI to go to turn off when the Phone is in standby. I have also turned on the Power Savings menu, but will do tests to see if that is really needed. So far 30% Discharge in 5 hours....
Here is a link to a guy listing all his settings ( http://www.samsunggalaxys3forum.com...ttings-worth-try-those-poor-battery-life.html ).... Experiment and make your own call. Unfortunately, you have to be very aware what you have turned on... or at least that has been my experience after the last few days...
Facebook is known to cause some battery drain. Anyway, you should install BetterBatteryStats (search the foruns, there's a huge topic about it). BBS will give you precious information about what is using your battery and how much it's using it.
Nevermind what I said... 4 hours today with "normal" usage and I am at 45%. The S3 is a battery hog compared to the Iphone.
I installed this morning bbs, ill post the prinț screen when i got my battery empty. An update i just bought a 4300 mili ampers battery and i still cant get the Stats from other members even with this.
I forgot to say GPS is off all the time aswell and wifi only when i need IT.

Taking a close look at the long battery review thread, while there is a lot of information there regarding individual battery usage, the screen-on and overall usage times vary by a lot. It is impossible to draw conclusions regarding why the results vary so much, because most people did not give enough relevant information there.
I think it will be very interesting if we all used the same *comprehensive* method to compare our battery usage. We could really discover important things about our individual usage and how it compares to others (and how to make it even better).
It is important to note that when battery life is low (in comparison to other G2 users), sometimes this could be because we are taxing our device with heavy usage (and nothing is actually wrong), but other times something is definitely wrong (wakelocks, bad phone reception, etc.). This thread will help each and every one of us (that get lower than expected battery life) understand which of these two possibilities is correct for him (something wrong VS taxing usage).
In order to do this, let's use the excellent "GSam Battery Monitor" app, which could be downloaded freely from the Play Store.
Please post your results when your battery becomes low (around 10 percent), after it was fully charged.
If you want an accurate opinion about your battery behavior, with tips on how to improve things, please provide all the attached screens (please provide the graph image in landscape mode, and sort it by "other"):
Is this really necessary? The G2 has a fat battery. But any amount of power can be drained if you drain it. Enough said.

I say let's give this a shot. This phone has a beefy battery indeed, but still, some of us are posting 7 hours screen-on times, while some of us only 4. Let's see what this thread will provide us with. I have a good hunch this will be a very revealing thread.

Yep, these are some solid good general advices.
I could only drain the battery to 50% today, so I'm posting this for now to get this thread running (and tomorrow I'll post the 10% results). It's funny because I have no trouble finishing the battery everyday, yet today it's giving me "problems". It's like it knows it is being monitored, and the battery hogs are afraid of being greenified...
Let's get over my results in the main screen:
Phone: yes, I did not use the phone to make phone calls. Not unusual for me...
Screen: almost 4 hours screen time, pretty impressive considering the phone has been running for more than 13 hours, and the battery is at 50%. On the other hand I did not make any phone calls, so this could be part of the reason for that excellent screen-on time. Btw, I'm using "Lux brightness control" instead of the LG2's pathetic brightness control feature, the Lux app itself drew practically zero power (as can be seen at the "App Sucker" screen, or actually, you can't even see it because it's too down in the list).
Phone Radio: At 7.9%, I don't really know whether it's good or bad, although this is definitely not a major battery user. I've attached the cellular reception screen too, just so people could reference with theirs. I think overall the reception is pretty good according to that image.
Wifi Active: The Wifi has been on the entire operating time. Most of the time it was connected to my home router, and some of the time it was not connected at all, but still on (when I was out of the house). I'm attaching the Wifi screen so people could see how much traffic the phone had through wifi, for reference. With only 3.9% battery usage, I think there is no need to turn the wifi off, ever.
Held Awake: The phone was awake for 1 hour (while the screen off, that is). Out of 13 hours being awake for 1 hour, I'm not sure whether this is good or bad. This will become clearer when more people will post their result here. It says that the power that was drawn during this 1 wake hour is 0.0%, I'm not sure if this is true, or some kind of inability of GSam to calculate battery usage for this awake period (if GSam IS correct, then I guess I don't understand what's the point of deep sleep, if the phone draws practically zero power even when awake...).
Bluetooth: The BT was on the entire operating time, but connected to a device only a short amount of time. In any case it drew no power according to this screen... like wifi, I think there is no need to turn the BT off, ever.
Regarding the "App Sucker" screen, I can't really say anything intelligent about this, no app seem to drain the battery too much. The 4 hours screen-on time was mainly spent browsing the internet, using Whatsapp, watching youtube, using XDA app (not even listed in the first screen) neither of which seem to drain the battery too much...
So, now that we have some reference (and a reference for a pretty good battery behavior, I think) It will be interesting to see how your results compare...
Just a quick question. I work in a building where there is terrible service. I mean so bad sometimes I get none at all. How does turning off mobile data save battery. Essentially your phone is still trying to connect to the mobile network all the same. I'm kind of looking for a technical explanation not just the 4g uses more battery type.

Don't forget, the vzw version will throw a wrench into these comparisons.
Thanks Devs. From my VZW G2.

If you have bad cellular reception, turning off mobile data can help, but as you said it won't completely solve the problem because the phone still needs to connect to the network so you could talk and send SMS. I think switching to airplane mode (and using WIFI) is the best solution for battery life in this case. Still, I think you should use GSam to really see how much battery is drained by your bad cellular reception.
I am using it now. Waiting until it drops to around 20% to post my results. Will get back.
Edit:
Here are my statistics. You think my phone just has bad reception and is in a bad area or there is something wrong with my antenna? My old Droid Razr HD was the same way, barely any service. I'm definitely not staying with Verizon. I pay out the noodle for "the best service" and I get crap. I live on Long Island outside New York City, my service should be amazing.

Ok, as promised, here are my 10% results:
Phone: did have some phone calls today, though nothing significant. I guess my usage can't really tell how significant phone calls are going to be with the G2, though this should not be a significant battery drainer for most.
Screen: As you remember, yesterday, after 13 hour phone usage, I had 50% battery, I had 3 hours 47 minutes of screen-on time. At that point I thought I might get over 7 hours screen-on time, but here I show about 5 hours 25 minutes. I guess that if I completely drained it, I would have gotten close to 6 hours, not bad.
Phone radio: seems similar to yesterday, about 10% of the battery... I still get good reception, as the image shows.
Wifi active: Wifi had been on the entire time, using 5.6% of the battery.
Held awake: So, yesterday after 13 hours of usage, the screen was held awake 1 hours. Today, after a total of 31 hours, the phone was held awake a total of 3 hours. It seems that the phone consistently is held awake for about 1 hour, every 10 hours of operation time (under my specific configuration, that is). I still find it weird that this "held awake" time did not tax the battery at all. How is this possible ?
Bluetooth: was on the entire time, not connected most of the time. Zero impact on battery.
Regarding the App Sucker screen, similar to yesterday, can't say anything special about this. This day I kept browsing the interned using Opera browser, and added another hour using Runkeeper with GPS tracking (with screen off). After a full cycle of battery usage, the main battery draw comes from the Home launcher, next is Opera browser, and then the apps become pretty much insignificant in terms of battery usage. Maybe two last points here: I'm using both Lux brightness control (to control auto brightness) and Delayed Lock (to remove the lock when connected to certain wifi points and BT devices), both of these apps always run in the background, yet consume practically zero battery, so high recommendation for both of these (they also work great with the G2). Last point, I'm using all the google location access services (everything is turned on there), and I really don't see this taxing in any way, using this GSam report.
That's it for now. Waiting for your results for comparison.

Interesting results. I thought this thread would be revealing, and it doesn't disappoint already.
Your phone reception is pretty bad, much much worse than mine. BUT, you can see that the difference in battery draw is not really significant between my case (I have great reception) and yours, in both cases the phone radio took about 10% of the battery. It seems that the phone reception qaulity doesn't make much difference on the battery (whether it's pretty good, or pretty bad. Maybe this will change if the reception is horrific... like 0 and 1). Comparing my GSam report to yours, you will gain practically no battery advantage by making your phone reception better (at least considering your current phone usage - you barely made phone calls, but still phone reception is also important in order to keep the phone connected to the network, and also for mobile data...). This is REALLY surprising, I thought that when comparing my excellent reception to your very bad one, if I got 10% battery usage (for phone radio), you'll get something like 30%. This did not happen at all, surprisingly!.
Your Held awake time is pretty much similar to mine, as evertything else is similar to mine (wifi active, etc.), yet you seem to get significantly less screen-on time than I. I can think of one explantion: I see you are using G2's automatic brightness control, which is pretty horrible, while I use Lux brightness control, which can reduce the brightness much much more, when it's appropriate. I really can't think of any other major contributor to your battery drainage in comparison to mine...
One thing still keeps me bewildered: why doesn't the "held awake" period tax the battery ?? I mean, the phone is awake, yet no battery is being used... how could this be possible ? Is this a problem of GSam which can't read this information right ?

When you turn off mobile data the phone stops searching for a data connection, thus this battery draining process is halted

Barely read through the details but I charged my phone to 100% last night, pulled it around 6am today. Been texting and tweeting moderately. Made a few phone calls, checked voicemail. Used the flashlight a couple times and took a few pictures, flash off.

This is true but look at the sent part of data of the phone radio. My received data is much higher then yours but I can assure you I only receive data via WiFi because my phone signal is so bad. Your sent in comparison much more data then me probably via your phone signal.
This is also very important. I had my mobile data OFF while at work today. I have a shift tomorrow where I will keep the mobile data on and post new results.
Edit: Also about the phone being kept awake and not using any battery. It does seem odd. Perhaps we should also use the orginal screenshots of the stock battery app (pending you still have stock rom).

But, I don't see how the stock battery app will shed any new light on the kept awake period, if anything, the stock battery app is less detailed regarding almost everything...
