Hi to all!
I'm thinking of buying either the Legend or Desire. There are two things that are important to me. The battery life and storing applications on the memory card. I suppose that the latter will be taken care of by the upcoming update to Froyo (if it ever happens!). How about the battery life? How long does it last on the Legend? Would anyone have any experience with the Desire vs the Legend on this? All comments appreciated!
Thanks in advance!!!
I don't have experience with the Desire but my Legend performs battery wise as expected from a smartphone I guess.
After the last update I discovered for example that leaving Google Reader open in the browser in the background drained power, so I now leave the browser always on the google homepage or kill it altogether when I'm not using it and I've seen an increase in battery life.
Anyhow, I give it a pretty intense use, on a work day I listen to podcasts on it for some hours at least, I connect it to my car bluetooth on the commutes (40 mins average total), read email, etc. And it lasts me the full day without problems, usually ending the day with 30% or more battery left.
It obviously depends on how each one uses their phones, as tricks like the Reader one I mentioned can make a difference.
The Legend seems to have slightly superior battery to me. My legend ends the day at about 30 percent after 2 hours of Bluetooth stereo playback, and plenty of latitude use and web browsing. My partner's new desire ends the day about about the same but without the music playing I do.
I was jealous of the desire when my partner bought it but If I had the choice of legend or desire again, it would be a hairline decision to buy legend again. If Legend had live wallpaper I would choose legend without doubt.

My battery life is even better than my old dumbphone. With medium use and pretty stringent management (ie. a task killer, bluetooth and wifi off unless I need them), I can get about five days on a charge.

Are you sure you are using the original battery ? I have never heard anyone reporting 5 days on any smartphone on even minimal usage. Legend seem to give 1 to 2 days max on minimal usage.

I have on two occasion to manage get three days but five days? Naah, not with the original battery.
Well if you disable APN the thing can last 5 days, but with net connection active definitely no way.
I can believe he gets 5 days out off this phone. I can get 3 days out of it with very good reception, some hours of browsing and 20 texts a day. Almost no calling and 3G always on AND WITH A GOOD TASK KILLER I always kill almost every app before putting it in standby you just need to know what you can and can't kill.
I can do 3 days with low use (maybe 10min calls and 20sms a day) and APN off most of the time.
With APN on I don't think it will last more than 2 days max
Just to clarify, I do turn off my mobile internet unless I'm using it at that moment, and yes I'm using the stock battery.

Sure, if you turn everything off it'll last a few days, but then might as well carry a dumbphone
Hey all,
I've been using Azure 1.0 on my Legend.
In case anyone is wondering what battery life is like on this ROM [I know I wanted to know before I decided to run it...] :
I've just got the best usage for this ROM in terms of battery life, since I started using it [0.5].
I haven't gone for Azure 1.0.1, and have stuck to 1.0 as I didn't have any APN issues...

Battery life was pretty poor when I first installed the ROM.
Then I used SetCPU to help....but it didn't seem to help too much...
Now I am seeing better battery life, like the above.
No idea if this is good/bad for this ROM, but for me, its the best I've seen yet....
...though still probably not as good as I first saw on the stock ROM before the update which messed up the stock SMS app was pushed out...
18 hours ~ 24 hours average. 1 and a half day or so if I'm lucky.
2G network. only switch on 3G when it's needed.
Wi-Fi, gps and bluetooth if needed. If not, it's turned off all the time.
always leave my Trillian (MSN/YM/gTalk) turned on almost all the time (like 75% of the time).
WhatsApp for 24 hours.
Mail fetching every 4 hours.
Twidroyd fetching every 15 minutes.
Urbandictionary widget fetching every hour or so.
15 minutes of call average.
Texting about 10-20 times a day.
And data counter widget running all the time.
Rooted and using a nice clean ROM called "CleanEclair 1.6.2"
Got a good Task Manager too.
It's definitely better than my old iPhone 3g.
BUT, if you are asking "Desire or Legend"
I may choose desire for it's better hardware.
PS: Sorry about my bad english.
Just to echo previous statements about battery life, I too get an easy 24 hours from my UK Legend. It usually has at least 30% charge left when I plug it in at night (10-11pm), this is from about 6am. As I type this as 4.30pm it has 69% left.
I leave data and wifi on all the time but only enable GPS & Bluetooth when needed. The phone connects by wifi at home but is in a marginal 2G location when I'm at work (cheers, Vodafone!) so probably has to work quite hard to keep connected to the network.
Google services and Twitter update constantly, Facebook every hour.
Don't run any task killer apps as I found they made naff all difference.
I do watch how many browser tabs I have open and what's on them thought as I notice that some pages really suck the battery dry.
Navigation is the real killer on the Legend (or any Android I guess); the combination of screen on, GPS enabled and heavy duty data use means it can go flat in as little as 3 hours. A power cable in the car will only supply 500mA, rather than the full 1A that a main scharger will, so it only really slows down the drain on the battery.
Other than that I expect the phone to fit my life, not the other way round. The effort that some expend to micro-manage their battery life really baffles me!
I get terrible battery life...
Typically 7-8hrs , now I use it for work but today I did 30ish minutes of calls, + maybe 1hr's worth of reading emails, sending data etc etc etc.
From looking at the "battery" part of the settings/about screen I can see that Display seams to be the thing EATING the battery..
is this normal?? I do use the power widget and put the screen down as low as it goes when I can however im really shocked at the power usage..
Ive tried using a task killer (advanced task killer) and JuiceDefender and neither make much difference...
any comments?? am I being realistic? I used to have a blackberry 8900 and it would easily last me a whole day , doing the same email load, websurfing, syncing etc, might even last 1.5days but I tend to plug the legend in whenever I can....
Is this normal???

Yup. Try lowering your screen brightness and see the difference. Screen and gps is the most battery-hungary.
Everything depends on how you use your phone. Try to avoid GPS and max screen brightness. And always remember to kill aps with any of the app killers, after you finished with it.

Good advice. Except on the task killing. Google around why task killing is not healthy for your phone.
my battery doesn't seem to show the correct level...I can charge it overnight on the mains an in the morning it has only got to 38%. Take the battery out and it goes up to 60ish%. Phone will last about a day, but can't seem to get a full charge into it.

I got my Vibrant a few days ago and as of today i can only get 4-5 hours max out of the whole battery and thats with heavy to moderate use.. does anyone else seem to have this problem.. im gonna return the phone and get a new one but does anyone else seem to have this?
I really dont understand why this is so bad..
4 or 5 hours of heavy use is about all I get. That is if I'm constantly messing with it. E.g. web, email, facebook,ect. However I think this phone has excellent battery life when I'm not constantly playing with it. Wifi definitely drains it quicker. And stupid apps like facebook. I periodically mess with my phone throughout the work day and by the time I get home I usually have about 75% battery remaining. I think that's pretty good.

THE BATTERY IS TERRIBLE. thats why i returned it, and the slow acrolling from screen to screen with stock software
I think you can only expect about 4 hours of awake time use on this phone. I haven't had much trouble with mine, I get about 13-14 hours per charge. But my phone its idle 9-10 hours of the day.

Then why are you still in the vibrant forums... move on...
I would think by now people would be use to the type of battery life you get with these types of phones. With heavy usage your not going to last all day just how it is until battery tech catches up to phone tech. I use mine a above moderate usage and some days heavy usage. From when I unplug it at 7:00am the battery is down to about 10 to 15% by the time I leave work at 4:00pm. Thats a lot better than my HD2, Cliq, MT3G and G1.

I agree 100%. Im seeing a lot of this. One thing I dont see is the "Vibrant Complaint" forum. Can't understand why ppl feel the need to come back in here if they dont like, dont have or feel they need to bash the phone from their experience. Get rid of the phone or keep it and be patient, its that simple... or am I missing something?!?!?

Im almost in the same boat, much better battery life then my G1! I can get from 8-8pm with moderate usage and music palying for the last hour. I was experiencing horrible battery life (8-2/3pm) when I was running notifications with Bloo 1.5.apk, auto brightness on, and Advanced task manager running. Now that I have cut the notifications from bloo (got gmail for this anyway), set brightness to manual setting, and got rid of the task manager I am regularly seeing, after bering unplugged since 8(its now 1245) and im @ 85%. Try trimming down the services you have running in the background and by an extra battery or a car charger.
Id like love to try mine out when i get it tomorrow because with
Mytouch Slide, i had Facebook, Gmail and all the usual stuff syncing and it lasted me close to 8-12 hours of Web, texting and just playing around with it throughout the day.
The Nexus One Was the same lasted me some good 10-14 hours a day syncing the usual stuff along with the weather and such. So Id expect the vibrant to be the same, or Else im returning it and thats the end of it. That also goes for lagging issues as well. And most likely get a different android phone or go back to the N1 and Switch Forums....
Have you ever owned a Smartphone before? Thats normal if you are using it heavily.

I get 6-8 hours.
I think 5 hours of juice is really good relative to your heavy usage. I always get 15 - 18 hours a day. That's with moderate use. Even playing a game of Armored Strike for an hour. This is the best battery i've had on a phone. I can easily get over a day and a half or even more once I settle down and stop using it so much more than I need to [ because I just got it.... ]
If this is what you consider to be terrible, I don't mind how terrible my battery life at all. I made a few calls, used GPS a few times, always listening to music.. some market downloads, pictures taken. SetCPU at 1000MHZ 100% of the time.

Disable Google Talk. My battery life was excellent (typically all day on full charge with heavy use). I signed into google talk one day and was lucky to get 4hrs before charging was needed. I deselected the auto sign in option and killed it in the running services section. Battery life has gotten so much better 70% after 4.5hrs.
i think the battery life for my vibrant is pretty epic. when i went to cm5.0.8 and cm6 on my g1 i calibrated the battery and thought i was getting really good battery life. then i got the vibrant. i could probably make it two whole days without a charge with how i use my phone (probably moderate-light compared to most on here).
but one thing i do agree with is this phone takes FOREVER to charge.
Hmm.....
Ok.....well I consider myself a moderate-heavy user...
On that note, I actually use my phone for work calls, emails, plus personal calls and emails as well....and i'm an avid gamer and already have many games on my Vibrant and use it to play them regularly.....then there is the fact that I travel for work....a lot, so I constantly using google voice search and maps to find where i need to go (never use the gps though)....I used the internet all the time, especially on WiFi (higher battery drain)....and don't get me started on the movies, music and youtube....plus while at work I have Pandora running from my phone throughout the day....
So how is my battery life? I unplug my phone every morning at 9am, with all that use I don't need to plug it in again till 10-11pm (12-14hrs!!).....by that time of course the battery level is at 5-15%.....But I'm definitely not complaining....
I do however disable the auto-brightness feature....AND turn down my brightness to about 30%....50% brightness cuts about 2 hours off of the battery life....
But a GREAT PHONE!!! Loving my new Galaxy S Vibrant

yeah, i feel the same way. As far as phone taking forever to charge, are you using the usb-computer charger or usb-wall? The usb-computer can be very weak depending on your system.
Charging from pc, i would wake up only to see 65%. That's pretty crazy. On the wall charger, it takes less about 4-5 hours every time.
Anyone loosing like 6 percent in the first 15 minutes after a full charge? 15 minutes ago i was 100% now im at 94....
I get better battery life than i got on my G1.
These are not cell phones... they are tinny laptops that you can press against your face and make phone calls.
This thing has more features than the $1200 gaming PC i built 2 months ago.
I had bad battery life the first day. Turned the phone off late at night and let it charge full. Battery has been wonderful since then.
I know a few people have been moaning about the plays battery but I thought I would post a couple of pictures showing how well mine has been lasting over the weekend, I'm highly impressed as I have been using it quite a lot too.

That is 36 hours since a last charge and counting with 39% battery left! during this time I have been using the internet, a few apps, the camera and XDA forum app!
The lowest the Play has latest me is about 7 hours but that is playing 3D games non stop, so anything pushing the gpu will drain the battery a LOT faster than shown above.
So yup, the Play has got a FANTASTIC battery
UPDATE: So far it has lasted 40 hours 8 minutes with 18% remaining
Update, 43 hours with 13% left
Damn i'm jealous. My play doesn't last that long. Did you disable some app's? Ans all sync on manual probably

I've got about 150 apps on my phone, Trillian constantly running to keep me online with IM protocols, syncing set to automatic, streaming podcasts with bluetooth and playing games from time to time, often with the screen on for long periods of time. I've been averaging 24-35 hours per charge, FAR better than my old Captivate which wouldn't last a day at any point.

Mine is rooted and I removed a few system apps, nothing major though, I have facebook and twitter syncing every 3 hours, email every hour.
My Play finally turned off at 2%, total time - 45 hours, 7 minutes
I have been using a lot this afternoon so did go down faster during the last few hours, highly impressed as my old samsung galaxy s would never last a day without a charge.
Yeah, I think it just depends on how you use it. For me I don't use 3G at all so that already saves, and then on top of that I selectively turn on/off bluetooth and wifi. I can game for like 3 hours straight and still have 75% left. I think the longest I've gone is 24+ hours with heavy periods of gaming throughout. If you constantly use 3g, wifi, bluetooth, and have a gazillion programs running then ur battery life might be way less.

This is the thing, On the other end of the scale I have only got 7 hours out of it when I was playing games non stop all day but that isn't bad as my old psp would go flat in 3 hours playing non stop.
It definitely depends how you use it but its good to know it can last for almost 48 hours between charges if you want it too!
Hello FK1983, thanks to your post I found the Battery Monitor Widget, which provide more information than the one I had before. I was reading all the post about the xperia play battery because mine was lasting just for half day.
I install this widget and noticed that where it provide the estimate charge use by the phone was showing more than 150mA, this even in standby, while yours was only showing 4mA, base on this I know somethign was running and eating my battery so I restart the phone and now it has been in 2mA while in standby and around 40mA and 60mA while writing msg or checking something else.
Is there any way to know what is eating my battery if I notice the last behavior again? so i can just kill it and not just restart the phone again
Another thing I noticed is that in your picture where you can see the battery information it says "Techno: Li-poly 585/1500mAh" while in my play says "Techno: Li-poly XXX/1200mAh" where XXX is the actual battery charge. Is this indicating that there is something wrong with my battery? I check it just to be sure that it wont be a 1200mAh battery model because of different region market but the battery has written on it 1500mAh. Any help will be appreciate.
Thanks.
Always check to make sure Gtalk isn't running in the background if you're on 3G (make sure your signed out), as it literally destroys my battery in about 6 hours.
And if anyone knows of a precise application that indicates battery usage (outside of the built-in one), I'd love to hear about it!
There's no question that the play has great battery life compared to most smart phones out there. I lost my charger and it lasted 4 days and still wasn't dead when I bought a new one.
any tip?
is a good time in u battery....

The battery mAH settings you can change from 1200 to 1500 in the options, that maybe why some of your stats look different to mine? give it a try.
Regarding running apps, you could keep a close eye on the running processes and see what is running there, or use a task killer or even an "app monitor" that records apps usage.
Folks that report awesome battery life:
Have you applied the 2.3.3 update? I'm still on 2.3.2, and I'm lucky if I get 5 hours of moderate internet browsing before needing to plug in (with about 20% battery left).
Also, in contrast to the OP's picture, my battery widget is consistently reporting between 200 and 300 mA shortly after a reboot. Can't kill any tasks to speak of either. Nothing is running to speak of except homescreen widgets.
Using launcher pro with its built in facebook widget, power control, fancy widget, pandora widget (not playing), winamp widget (not playing), battery monitor widget, google plus widget, and a volume control widget. Running a live wallpaper as well. With all this running, is 300mA a reasonable usage?
I'm on 2.3.3. 5 hours seems awfully short for just web browsing...
I get around 24 hours with 15 hours of Facebook & ebudddy....around 2hours of web browsing and abit of gaming
Sent from my R800i using XDA Premium App
Im on 2.3.3 and i get around 24 to 30 hours facebook and surfing the web for around 2 hours and sending msgs and making some calls. if you are getting 200 or 300 mA i think something is killing your battery. On idle Im getting around 4 and 5 mA sometimes 12-15 mA(I guess something running in the background) and when using the web browser, WIFI on and GPS on im getting around 100-150 mA the most being really bad.
I'm on the R800X. I guess verizon really screwed this phone up.
I rooted my play last night and my battery seems to drain quicker.
I don't know why I havent done anything to phone yet as iv been at work all day. And since I havent replaced all my games yet iv used it alot less today than I normally would but the battery seems to have drained more than usual.
Would a task killer help prolong battery life? I read somewhere that a task manager is not needed with android but im skeptical

Android has a build in task killer, having two will only drain battery. try setcpu and remove as much bloatware as you can(need root).
I just updated my play to 2.3.3 and battery life seems worse for me than 2.3.2. I can barely get through a day of light usage (no gaming, and ard 1 hr's worth of web surfing, switched off most of the updating from apps like facebook, email, pulse etc to manual).
I tried battery monitor widget and my Battery health shows up to be 'null' (my friend's htc desire hd shows 'good'). Would any kind soul be able to tell me if there's something wrong with the battery or the software (mine is stock Singapore xperia play firmware 2.3.3).
Hi all! I just get my galaxy tab 7.7 wifi only and I am very disapoited with the battery. It lost 1% each 4 minutes with just normal surfing ( screen brighness 30%) . By ipad 2 I lost 1% each 10 minutes and the screen is biger, brighter.!!! Any suggestion?
Ps: im stanby is ok. 2% for 10 hours.

just found this out a couple of minutes ago if you are using a search engine use bgoog.com aka black google it uses a black background so you can minimize use of the amoled screen and reduce battery consumption hope that helps you
black baground webpages tend to use less power than a white background
as for me battery life is better overall from my old galaxy tab p1000
Yep, I have a lot of black background applications as well and battery life is superb compared to my 6-month-old p1000, just be sure to properly cycle your battery from time to time to minimize battery degrade
My experience is that I get about 8.5 to 9 hours of screen time on a single charge with wifi turned on all the time. That's about one percent loss every five minutes.
I had heard that the iPad is rated as a ten hour battery but it seems that you have been very lucky and got a unit giving you nearly 17 hours of screen time. That's incredible and anything is going to seem like a disappointment after that.
If your unit is new you may find the battery life improves over time a little bit but I wouldn't expect much more than nine hours with wifi on all the time. The adverts claim ten hours and one review site managed twelve but I don't know if that is just looping a movie or if wifi was on at the same time.
Anyway, 8 hours is enough for me

i think you may have an app thats running in the backfround that doesnt exit even when not in use had the same problem before with my old p1000 i thought i had a lemon unit but the culprit was the a certain app forgot the name it was about a year ago you may want to use the samsung task manager and see if any app is running in the background or use a task manager on the market
and just to add, do turn off the background data on the settings, it's another power hog
I find it hard to believe that the iPad 2 can go for 17 hours of usage. Engadget's battery test says that their 7.7 lasted about 12 hours, 1.5 hours more than their iPad 2 (looping video, wifi on, screen at 50%, I seem to recall).
Also see settings> about device> battery use to see what's eating the charge. Normally, the lion's share goes to the screen. But games can use significant amount of charge too.
I've been able to about 10 hours of continuous usage (light browsing, email, xda, kindle, pdf reading on either repligo or mantano).

For video playback the Tab7.7 will have a longer battery life since it is using GPU decoding as compared to the Ipad2's SW only. But when it comes to surfing and everything else, generally for anything else apple devices can outlast samsung devices or andriod.
According to battery widget pro estimates, if I stick to reading on the kindle app, as I have been doing for the last couple of hours, I will be able to last another 18+ hours. Wifi is on, screen about 15%, background auto sync on. (Since it's a longish Neal Stephenson that I'm reading, I'm going to need that much time.)
Incidentally, I found battery widget pro very useful. Have it on each of my Android devices.

Aaawww, I feel so bummed to post this, cause I am otherwise absolutely in love with my galaxy tab 7.7, but I feel a bit iffy about the battery life aswell. I switched to galaxy tab from Asus Transformer TF101 and I actually feel like the battery on my previous tablet lasted waaaaaay more, even with the wifi switched on permanently. On my Galaxy Tab 7.7 3g I can easily lose 20% of battery power during a half an hour of browsing the internet on low brightness, with wifi, gps, bluetooth and background sync switched off...that is hardly the "phenomenal battery performance" mentioned in all those reviews. I use ADW launcher, not so many widgets, I dont even play music, games or video and still the battery will not last through the day at all...I mean..I only would use it for reading an ebook, browsing the web and facebooking 1 hour on a bus in a morning and another hour in the evening....but no chance...the battery wont last that long. It would exhaust the first 40% on my way to work, and come down to 30% during the day (when used very rarely). I can easily last the whole afternoon with switching the battery saver ON every time I am not using the tablet, but to resort to that, and to switch everything off and lowering the brighteness to miminum just to be able to browse internet for an hour and lose almost 50% of battery power by doing so, feels really desperate. I still dont want to believe I am the unlucky one to get a bad unit with a dogdy battery...what should I do to make sure tis not the case? Is there a test I can run to see for sure if I have the battery which drains the same way as the others or not??? Thanks in advance for any suggestions.
i personally have no battery problem with surfing internet . because i have use customized css in opera mobile, every page become black with white text.

Ok thanks, but that does not really help..I just wanted to know if there is a way of knowing for sure (e.g. by running a certain test or something) that my battery is officialy flawed compared to the others in these units. All the reviews for this tablet mentioned an exceptional battery life and yet I am loosing almost 10% every 10 minutes of browsing (not playing video or music, so not a heavy use really) on the minimum brightness, with gps, wifi, bluetooth, background sync, vibrations, animations switched off...does not seem ok to me.

Install a battery monitoring app (e.g., Battery Monitor Widget Pro) so that you can track/log usage.
No, your numbers don't seem right.
Check what been taking up all the juices in setting-about-battery usage. I had similar problem previously when my exchange push mail was not working correctly and keep connecting to sever. Did a hard reset, everything is back top normal.

I dont have any battery life complaints yet as TBH, i dont really know what to expect from a 7.7 Inch screen with 5100mAH of battery, suffice to say that it out lasts an Ipad2 on anything but web browsing is already good enough for me.
My battery is very good, light years aheadof the Blackberry Suckbook that it replaced. I generally get a full day of heavy use with Wifi and 3g browsing, and two days of "normal" use.

if your tab is rooted and you know the system files you may want to install nobloat and remove system apps that you don't use tried it and lowered my actual ram use to 400 to 500+ and keeps my tab snappy be warned make backup before using just to be sure
and another thing always try to clear memory using task manager when your gonna let it standy i found it to use less battery than when many apps is running in the background when on standby hope that helps
No matter what I do the battery will not last me a full day. A full day for me is about 18 hours. I use my phone almost none at all while at work and I use juice defender to keep data and wifi off while I am not using the phone. I would say 80% of my day is wifi and only a little is LTE. I monitor my task usage and the only thing that ever shows up is screen...there are other apps but very little usage. I use auto brightness. Could that be it? Unless JD doesn't work well with these phones, I just can't figure out what it is. Unless of course its just normal...
Phone has to last me 18 hours with moderate usage. If it doesn't, I need another phone.

The big killer of battery life is when LTE doesn't have a good signal (inside a large building). Connecting and reconnecting to the tower is what always kills my battery. I suggest you look and try those "turn of LTE" hacks around. My battery lasts me about 20 hours with moderate usage (but I am always in a great LTE location), and about 12 hours with heavy usage.
As long as your signal (wi-fi, LTE, HSPA, whatever it may be) remains good, you should have amazing battery life. I often take my phone out for 16-17 hours between charges and have ended the day with anywhere from 60% to 25% of the battery life, ranging from light to moderate usage.
For me, an average day is on wi-fi for at least 90% of the time, but a recent trip I had to Chicago (LTE all day, no wi-fi) showed similar results - and that was with some more moderate use while traveling! Not sure if there is much you can do about your signal, but I know my last phone (Captivate) got worse signal in my pocket vs. on my desk. SIII doesn't seem to be having as much of an issue, but still something to consider if necessary in your case.
I live in Dallas and have great LTE.
I just copped the sgs3 today and have not put it down my batt isn't that bad. 8 hours st8 on it lol

OP, one suggestion I have...
What makes this phone a winner over my One X is the removable battery. I believe you can get a second stock battery for about $30, and I saw a charger and battery for around $40 earlier. Maybe you should pick up a spare? I realize it's not ideal, but it's an option.

I'm in Vegas, lte rocks and I use my phone constantly. I can't get 4 hours so I just ordered an Anker 2200mAh.
I'm not on wifi but the Lte network in Vegas flies too which is just an additional $$. I've just got juice defender ultimate. I know a lot of people swear by it but I can do it better and faster myself. I'm a heavy user and if we could just turn off the Lte u and then maybe slow down the processor., I would be fine. It's ridiculous we still need additional batteries.
Whenever I leave my house I do the following in settings.
Power Savings I now just leave on.
I either completely Restrict background data or you can do by application in Data usage and go into Accounts and Sync and turn most off. Anything not Google is off and under Google I just sync my calendar, address and Gmail.
Now if we can turn off Lte, I will be fine I think.

I was running rom that was supposed to be stock but debloated and I installed the cpu1 sleep apk and I got horrible battery life. 5 hours and I was completely dead. I could not see any partial wakelocks. I was about ready to box up the phone and ship it back to Amazon. I flashed back the complete stock rom and I got great battery life. 12 hours, 3 phone calls, 3 push mail accounts, yahoo checks every 15 minutes, 1 hour streaming and the Windows Weekly podcast and I still had 65% left. I was moving so I didn't get a chance to browse or do work crap on it.
Hell with it, I'm staying stock till CM9/10 gets most of the bugs worked out.

Mine is about the same, but that isn't good for me. I am 7am-3am daily. There is no way your battery is making it 20 hours, just like mine.

I live/work just outside of an LTE area, and lately have been using my phone pretty light due to not being able to use it at work other than when I'm on lunch. I get almost no signal in my entire building, so 75% of the day I turn airplane on so my battery doesn't get raped.
So for me and my use recently, the battery has been doing good enough for me.
the standby thing raping my battery is weird,same thing with maps even though i never use it... but i guess both are common. Chrome use was at 3% and i forgot to check screen on time.
On the current charge I'm siting at 47% at almost 24 hours, about 1hr 15 mins of screen on time. 30 mins of voice, 10 of chrome...but i accidently unplugged the phone right before i went to sleep last night instead of starting this morning, and i just took a nap so again there is a lot of sleep time
Take all that for what it's worth, which I have no idea lol

I had the same issue, then discovered that going through a charge cycle fixes the issue. I got only 5.5 hours of use off my first charge (80% of the time on standby), but things improved enormously after recharging it to some extent, then unplugging it. See my post http://forum.xda-developers.com/showpost.php?p=28742643&postcount=297
I've had my phone unplugged for an hour now after the last partial charge, and it's actually gone from 48% then to 51% now, as the battery is still recalibrating.

The cell standby reading is a bug in the software, it is reading something like 10 times higher than it is supposed to.
I recently got a razr HD and i noticed my battery barely lasts a day. I had a flip phone before and it would last a week on one charge, i know i wont get the same type of battery life. I downloaded juice defender and set it to turn off my wifi/data when not in use. It has helped a bit since before that my phone would lose 2% battery an hour just in standby. I haven't downloaded any task killers, but when i'm done with my apps i go in to the settings and close them.

Two things to fix,
one, adjust your brightness to auto. The higher the brightness, the faster your battery dies, that is massive screen use.
two, poor wifi/cellular reception = ****ty battery, the phone uses more power to lock onto signal.
Dont use task killers, they do more harm than good.
I adjusted the brightness on my tbolt and I doubled battery life

Hmmmm. i wasn't very through with my post, but i have mine set on auto brightness. My wifi at home is usually 4 bars and 3 if im in the basement. I get 4 bars LTE for 95% of my day. In the main building on campus i get 1 bar if im lucky but usually its out of service so i depend on the wifi. The only thing i use my phone for is listening to music on my way to school, texting, email (but i set it to sync every hour), some light internet browsing, and calls.
Edit: Also on a sidenote is the smart actions useful? It seems like it does the same thing like juice defender.

yes, smart actions does the same thing with less battery,
UP your sync time! The more often you sync the more battery you use! I would put it on 4 hours and only sync if you need something important.
Turn of your cellular radios at school and that will help battery
Clearly your screen is consuming most of the battery. Try lowering your brightness, If you used it to text and kept the screen on for long time.. it might have consumed battery in that period. Not sure if its helpful or not .. but here are my battery stats after a normal usage day.

The 3 hours in sync shouldn't be eating up my battery though, but i guess every bit helps.

nah, just change the sync settings to longer and set your brightness to auto and see what happens over the next few days and report back.
I noticed the biggest difference when turning off WiFi and mobile locations.
Also 4.1.2 seemed to increase my battery life dramatically too.
I don't think setting the brightness to Auto is the best for saving battery. When in auto, the light sensor is turned on and some processing has to be done to define the brightness every time the screen is turned on. And that consumes energy.
I always keep mine at 50% and, when in very bright places, I go for 100% brightness.
Hi again, today i disabled my wifi and data manually whenever i wasn't using them and manually enabled it whenever i needed it. It worked a lot better and i left my house with 85% charge and i used my phone a little bit more than yesterday and it used up a little bit over 25%. I also played around with my juicedefender settings and hopefully it will work better. I will set my brightness to 50%. I'll post back in a few days. And is my battery working properly, because i honestly expected it to last a lot longer. Also thanks for the suggestions.
I really like 2x battery for controlling battery usage by data connections. There a light version as well. It basically turns off mobile data when the screen is off and turns it on when the screen is turned on. It can do the same for wifi as well. The light version will reconnect and sync everything every 15 minutes (or you can turn sync off). I paid for the full version and it allows you to change the sync time to longer increments. I use it mostly because I don't want to have to remember to toggle and where I work the 4G signal isn't so great.

Have the same problem! Brightness is low, internet is off, when I don't need it, still the battery is weak!
You said you had a flip phone before and the battery lasted a week, is this your first smartphone?
Smartphones have a 24 hour battery life at best, This phone has an above average battery I have had 48 hrs out of it..
other things to get in mind is the ROM you are using, I see you are on stock Ice Cream Sandwich, ICS have a good battery life, I have tried Telstra Jellybean and it was not as good, I also get excellent battery life with epinter's CM10
I am very satisfied with the battery life! I also recommend x2 battery, which seems to prolong battery life with little to no impact on the usability of the phone (at most a potential short delay on emails when not on wifi). I generally use wifi whenever possible which use much less battery than the mobile modem. Also I have disabled a few stock apps that I don't use e.g. the non-gmail (stock) email app. The phone is not rooted and using stock o2 JB rom.

Wow sick battery life, do you have the MAXX HD?
I think it is as well. I admit it may be a little "inflated" by using Wi-Fi mainly rather but impressive nevertheless. Wi-Fi or not I generally experience good battery life. I have the normal non-Maxx edition bought in Germany September last year.

Also have a look using Better Battery Stats app to see what your most battery hungry wakelocks are, especially Kernel wakelocks.
I had issue when I first got my razr as I was using it on a network that doesn't have Fast Dormancy yet the phone has fast dormancy enabled, so i had to freeze it and battery life improved a little.
But unfortunately fo me the main problem was where i live. I'm in a city, so it's not a lack of cell towers, but for some reason at home my battery usage is insane while connected to mobile data, 9%-11% an hour with no use compared to 2%-5% elsewhere around the city. (Am thinking it must be getting bounced from tower t tower trying to get a better H+ connection) As soon as I switch over to wi-fi tho (which I have set to always on,) my battery usage drops to about 0.8%-1.2% per hour in standby.
