what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.

Wanted to know from those getting 2 days out of the mini pro, what are your systems settings to make this possible.
1: I have my screen to less than 50%, can only still manage a day.
2: Do you guys turn off 3G HDSPA?
3: Does wifi use more or less battery than HDSPA?
4: Any of you using a blue tooth headset?
5: Any specific apps to kill?
6: Any special battery conditioning done? If so steps?
7: Do you guys have exchange e-mail on? push or pull?
The battery meter is showing more than 50% going to the screen.
Good that it seems I don't have an rouge apps and the wireless doesn't seem to take up too much battery, but a let down that I can't get more than a days worth of battery.

Why are you trying to make your battery last 2 days? Do you not have access to a charger everynight?
Also I do not recommend you 'kill' any apps, due to the nature of Android. If you 'kill' an app, it's very likely it will just start up again, using more CPU cycles than if you just left it idle. This is especially an issue if you are using an auto-killer.

1. set 40%, add widget at front wall for fast switching (to 80%)
2. turn off mobile network (data), add widget at front wall for fast switching (to enable)
3. -
4. no
5. using system panel lite to clean and root uninstaller to remove apk at system app (currently memory at 230M-240M)
6. restart phone 3 time per day, use 1800mAh, charge phone when >5% energy, to 100% (45minutes), turn off while charging is more better.
7. no - exchange e-mail running at background processor (any unwanted background I will kill or remove; currently only 3 apps still running)
use dark theme/wallpaper for energy efficient (low brightness) and use earphone to listen music

I'm not sure what value this message is supposed to provide. I've seen folks post that they can get 2 days or better out of the phone, if so what's wrong with wanting to do the same?
Also note that there are times when it's inconvenient to charge and I'd like to defer charging. I'm pretty much out of juice by end of day the work day, but would like to have a few more hours of battery left, having the phone on the charger all the time isn't always convenient.

I understand if your phone is starting to go flat then you might want to start conserving battery, but if you have the ability to charge it then why not?
I agree with r33p. Using a task killer is possibly one of the worst things you can do to try and save battery. Using less memory does not save battery at all.
Also im not sure if this is true, but using a dark theme does not save battery as the backlight is still on, but screen is just 'hiding' it to create the black you see. So if anything it uses more battery.
I tend to keep a widget on my home screen to turn off data, wifi, and bluetooth. I turn them on when I need them, turn the off the rest of the time. As long as you aren't doing heavy internet browsing on your phone, you should be able to get two days use out of it.
Hopefully we'll get some custom roms for these things so I can justify rooting my phone. Then I'll uninstall all of the stock apps I don't want, both to clean up my app screen and to hopefully stop some of those background processes I don't need.

I must agree. Using a dark background does not save battery. That only works for oled or amoled based screen like the galaxy s series. Also they're right, don't use a task killer. Terminating apps just consumes more battery.

i can last 1,5 day without charging.
if i dont do anything special besides reading mail and answering a few whatsapp messages i do about 3-4% an hour. if i dont do anything at all, like at night, it uses 1-2% an hour.
1.screen is 35%
2.i have 3g on. sometimes i put it on 2g only
3. i dont know but i turn off wifi en bluetooth whenever i dont need it.
4. i use bluetooth in my car tot connect my phone with my car. unfortunately this uses a lot of battery by being just connected.
5. i kill the popgames, this uses a lot of battery
6. most times i let the battery go empty and only then start charging with the powerconnector, not through usb with a computer.
7. i dont have exchange but imap push email and another account pop3 which connects once every hour. i use the app k9mail
last weekend i did 2,5 day but i was abroad and didnt have roaming data and turned off wifi en bluetooth.
i did 1% a hour except when i was driving and connected my phone to my car.
but still 2,5 day

Does 2g only save battery over wifi and 3g? If so, is it sufficient for e-mail?
Mike
I normally put all of my most used widgets on the front page for quick access
3g or wifi pref. 2g is painfully slow.
Yea and forget appkillers,delete the apks or freeze the unwanted services.
The tricky part - what (not) to delete.

You need root to do that, however.

yes 2g saves battery
i was told that because of the continues switchting between G, 3G and H the battery consumes a lot of energy.
when you put it on 3g only or 2g only it saves battery.
becasue i dont have 3g everywhere i go i put it on 2g so that i can make calls everywhere i am.
if i need to do some things on the internet i switch it back to 3g.
2g is enough to recieve mail and whatsapp messages.
my mail wont come in as fast as wifi or 3g but that doesnt matter to me.

I have about 2 days. Currently I'm on 82% 12h since charge. My experience:
1. I keep 3G switched off most of the time when I'm outside. Only if I really need the speed for uploading a photo or update an app.
2. I keep Wifi running all the time at home.
3. I have disabled Location&Security both Use network and GPS. These seems to drain battery even if maps and latitude is disabled.
4. In the carrier settings I have disabled automatic mode and going for manual mode and selected my carrier.
5. I always use the back button on any app until I reach the home screen before locking.
My idle drain is about 1.5-2%/h when I'm at home with wifi. Outside with 2G it's draining a bit more and with 3G it uses insanely much battery.
I have lot of push services running (fb/g+/twitter-notifications, Whatsapp and gmail + an Exchange account)
I have also noticed that the battery calibration is a bit flaky. From time to time I run the phone until it dies (sometimes at 8-10% but sometimes at 30%). Then I'm unplugging the battery for a minute, plug it back and charge and it have calibrated and doesn't die at 30%.
Another thing I have noticed is that I can't get more than 4172mV charge. The battery should be able to charge to 4200mV.
Two good apps for monitoring battery usage is BetterBatteryStats and Battery Monitor Widget (which is more than just a widget)
do you guys charge till it reaches 100% or just till it turns green?

thats one other discovery I have made.
when the phone says 100% it's actually still charging (can be seen that there is a charge indicator at the battery and also can be seen from Battery Monitor Widget)
Another thing is that when it has reached 100% it starts to drain battery until it reaches 95% then it starts to charge again. (nothing uncommon with that) but the phone still shows 100% so sometimes when it's unplugged it can actually be at 95% (but starts to countdown from 100%).
Battery Monitor Widget can alert when it's actually fully charged with a notification.

i have a dutch language installed so i dont really know what the exact english translation is.
Dismissing things like sync and widget updates, etc., which option do you think ultimately saves more battery life? On the one hand you have wifi constantly locked on even if the phone is in deep sleep for hours. On the other hand, if you find that you use the phone quite a bit in spurts, wouldn't it seem that the wifi constantly turning on and connecting, then turning off during sleep, would actually use more power than just being constantly connected?
It might be a bad analogy but I liken it to when you turn a car off and then on as it uses more fuel compared to just letting it idle for a few minutes instead. Would this be the same with power consumption on our phone?
I've seen many articles that indicate Wi-Fi is much better on battery life then using 3g. So I've been running my like that for awhile. Not sure about the results though. Wi-Fi is now my second biggest battery drain, behind Display.
Mine is set to stay ON always. I get better battery life when using wifi.Some say the opposite, try both ways and see which works best for you.

I have the policy set to sleep when off. Even when I do use my phone regularly, I find that at times its going to help you save more battery life without having wifi constantly scanning for access points.

Just up the scan interval.
Standby drain of our wifi chip is VERY low, less than 1/10 that of the original GalaxyS series if power_profile.xml is correct - and it's FAR more power efficient to transfer data over wifi than cell radio on our phones for a variety of reasons.
I want to test a theory guys. Anyone else who feels they want to be a part of this feel free.
This is what I want to do. I want to test the actual draw of the screen in a normal days use over 2 days. The first day set to ~25%, the second day set to 75%. What I want to see is how many minutes at those brightness the screen was on. And the difference in the usage on the battery on those 2 days.
You don't have to be dead on with your estimation of time the screen was on, but try to be within a few minutes. If there isn't much of a difference then I believe the screen actually is pulling power while "off" and killing our battery unnecessarily fast.
There is no reason on 12 hours of battery, with screen on less than 30 minutes total that it should consume 65% of the battery! I don't actually see my battery drain 65% right before my eyes while it is on, so something has to be happening behind the scenes.
Edit 1: Post a screenshot of your results from both days. Tell me what connection type you used through the day. What ~% your screen was set to on both days. I only need the screen percentage changed, as long as everything else is consistent it is irrelevant to this test.
Day 1 do a low 20-30% brightness, day 2 do a high 65-75% brightness.
Edit 2: I just realized that when under battery use you can click the specific process (here being Display of course) and it will give you the exact amount of time used by the screen. If you guys could, please post both screenshots, as well as give me the accurate amount of time the display used battery.

I don't know if you ever had the original Dinc (I see an Inc 2 in your sig) but on stock ROM that phone constantly reported 60%+ Display usage no matter what you were doing, even lightly used. I crank my brightness down to like 20% permanently. I don't use it outside, so I don't need it super bright. Did it on the Dinc, and I'm doing it with the Rezound. Usually see display around 30-40% unless I'm using it heavily.
And it's not consuming 65% of the entire battery, that is 65% of the total drain is attributed to the display. SO if your battery has gone from 100 to 90% in 30 minutes, and 65% of that is display, your display has drained 6.5% of the total battery.
This is why I said over a day dude. I didn't say tell me what it says right now. If you don't want to be involved in the experiment don't bother posting in this thread. That goes for everyone. I stated 65% of the total consumption. If you really think I am an idiot don't waste mine or your time posting because you will just piss me off and I will report your posts.
If you had read the post correctly you would understand that I get 12 hours or less of battery life while only using the screen for maybe 30 minutes out of that 12 hours. Yet it reports 65% of the consumption is due to the screen even on 20% brightness. Theoretically that means I should be able to use my phone screen for 30 minutes straight and should be able to watch my battery drain 65% in that 30 minutes, which it does not. Therefor there is something else pulling power either stating it is the screen, or the screen is drawing power when off.
Hostility unwarranted. I misread your post, simple explanation.
I'll try cranking my brightness up and see what I get over a day of moderate use, how about that to make up for it?
Lol, Sorry man, I haven't seen you post here before. There are so many members who just post to post. Everyone has their 2 cents, you know what I mean
Appreciate it though!
I'm willing to try this. I'd have to start tomorrow. I also have a few basic questions.
1. How are you estimating time screen is on? Is there a way to do it other than just me paying attention? Cuz that's hard for me.
2. Does that stats page need to be reset at the beginning of each day? Also, where the hell is that thing? I've been to every setting on this phone exploring it and then when I want to find something again I can't!
3. Does it matter what power mode the phone is in?
And I was thinking to add to the test it might be interesting to see what having the screen on "automatic" would do.
1. I don't know of a surefire way, if someone else knows let us know! Otherwise, just a rough estimate is fine 30 mins ~35 minutes really. As long as you don't overshoot too much.
2. You don't need to reset the stats, they do it automatically after being on the charger for an extended period. So if you charge overnight and take it off it will only show from when the phone was disconnected. Settings >About Phone > Battery >Battery Use.
3. Power mode should have no relevance. But I am using "normal".
You're going to have to specify if WiFi or 4g/3g is to be used. I have noticed over the past few days that 4G consumes roughly 1.5-2%/hour less battery than WiFi does. On my Dinc, WiFi would draw a lot less power over time than 3G, but not so with the Rezound. So now I leave it on 4G while it sits idle at work unless I need to download something big, in which case I'll switch to WiFi, even though I have unlimited data and technically don't need to care lol. But I found that with WiFi and 4G both on and WiFi connected, my phone was burning like 5.5% per hour of battery. With 4G on only, I'm going through ~2.5% per hour (these are both with the phone sitting idle, usually in the morning when I'm busy at work). That's pretty much what my Dinc was doing on Wifi. I'll have to try it sometime with WiFi only on, and 4G off to see what happens.
But regardless, please specificy WiFi or 4G. Any testers that volunteer for this will need to leave that connection on as their sole connection during the duration of the test, save for a few mins of variance here and there.
Doesn't seem that should affect how much power the screen itself uses though. He just wants to test screen battery usage, not overall battery usage.
EDIT: Oh, if we are talking percentages then yes, it would matter. I generally leave my phone on 4g unless it decides to turn it off. And I switched to wifi a bit ago since I was required to to download an app from Amazon.

With 4G on only, I'm going through ~2.5% per hour (these are both with the phone sitting idle, usually in the morning when I'm busy at work). That's pretty much what my Dinc was doing on Wifi. I'll have to try it sometime with WiFi only on, and 4G off to see what happens.
But regardless, please specificy WiFi or 4G. Any testers that volunteer for this will need to leave that connection on as their sole connection during the duration of the test, save for a few mins of variance here and there.

You are describing exactly the opposite of my experience with 4G vs WiFi battery consumption.
Hmm, interesting. Maybe I just have really good 4G signal? I too thought it was weird, given my experience with the Dinc being exactly the opposite of the Rezound. Trust me, I'd love to know why it happens that way too lol. But again, I shouldn't care because I have unlimited data, and the 4G is faster than the WiFi here at work and about as fast as my home connection (I average on the lower end of the 4G scale, about 10-15Mbps), so I'll probably just leave it on 4G for now unless I'm at home and need to FTP to my laptop or something.
And feralicious, I agree to an extent, but to get truly accurate results we at least need to know what X person was using for data over Y person, since both connections will draw power at a different rate. The only other accurate way to do it would be to keep the phone in airplane mode. And since he's using approximately 5% per hour of battery, whereas I'm using 2-3%, maybe he's on Wifi where I'm on 4G. As in any testing you need to have a control along with the variables, and the data connection is a big variable that could easily be made a control. Just my $.02

Yeah, I just realized that and edited my post, didn't see you had responded.
For the record, 4g seems to pull more power than wifi for me as well.
Just post a screenshot of your results, tell me the amount of time your screen was on, and what your primary connection was. This is the only info I need. Your connection will only minutely affect the percentage that the screen draws. I only want to know the difference between screen high and screen low. So long as everything else is consistent on your end your results should be accurate for what I need.
Looks like I have to extend it out a day. I set my phone to 75% brightness and go figure it is the day that the network is having outages. My battery lasted ~2 hours today doing nothing.
Wow. 2 hours?!?! Will start the official test tomorrow as well but for the record my screen was also at 75% and I got almost 10hrs and I texted, shopped for and played with apps and watched a few app videos. I turned on wifi for a few hours due to network outtage.
Posting results even though they're not considered official. My screen was on approximately 1-1.5hrs in my estimation.

lol I woulda been in the same boat, if I didn't have a coworker alert me that 4G was out. I hadn't looked at my phone all morning, and woulda had a dead phone from it constantly looking for a 4g signal.

I had no idea, my phone was in my pocket and I was busy all day. Never felt it ever get warm, pulled it out of my pocket when I had some down time to check my G+/FB/Twitter and BAM.. phone wouldn't turn on. Luckily a friend had a charger and let me hook up. Turned on the phone to see the battery had actually died. I took it off the charger at 11:30 and it was dead before 2.

Thanks, I will be trying high brightness again tomorrow.
I couldn't get a reliable test because I had a stupid setting left over from my experiment with Economy mode that turned WiFi off after 15 minutes, so my data is skewed a bit from the first day to the second. (Plus the roving 4G outages caught me last night and my battery went from full to 5% overnight.)
Also, I use an app called SystemPanel (bought the Pro version) which gives me nice plots of my usage and screen on time, if you're interested in more data like that, you could look into it.
I just realized last night if you click the process in the battery use window that it will show the time that process uses power. Soooo.... I need everyone to start from scratch and give me the accurate amount of time the screen shot is on, for both dim and bright settings. Sorry guys! OP updated.
I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:
http://www.amazon.com/Xantrex-XPowe...IC/ref=sr_1_12?ie=UTF8&qid=1337500958&sr=8-12
Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:
Latest ruu-cleanrom de 1.4-take it easy on the apps and widgets!

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
Is there any way to prevent this banner (picture attached) from appearing when Wi-Fi is initially connected? I use Juice Defender to disable Wi-Fi when the screen is off and it is very annoying to have this pop up every time I unlock the phone.
Every time you unlock the phone? Mine only does that on actual connects and thats it. You must have it set to turn off wifi during sleep? If that is the case... some dev will have to find where that is burried at in the OS. Easier thing to do is let it stay connected. Better on your data anyway and if youre on unlimited still why bother with wifi at that point?

I purposely use Juice Defender to turn off data and Wi-Fi when the screen is off. Both turn back on when the phone is unlocked, which is why it appears every time.
ahhh on rooted phones with custom roms i don't recommend Juice Defender. It's usually more trouble then it's worth and more times then not ppl say it uses more resources then it saves (battery). And why data when screen is off? Just curious since you'll only ever get just texts and calls then and miss everything else notification wise.
My guess for what you're asking for is someone would have to make a special effort to do it.

I would suspect that this may be doing more harm than good for your battery life. My battery will last much longer using wifi if available. Maybe instead of using Juice defender to turn off wifi, you could try using the "wifi off during sleep" option that is built into the phone. I think it will accomplish the same thing and it may disable the pop-up within the system.

I noticed that sometime with this phone (and the S3). "Off" doesn't seem to mean "off" anymore. My phone could mysteriously discover a known wifi network and suggest connecting to it while the wifi is supposedly turned off. If it is truely off, then it wouldn't know there is a network available!

I find that turning data off too dramatically reduces standby drain. It automatically turns back on if an MMS comes in and periodically turns on to receive other notifications. Juice Defender has worked pretty well for me and I'm on CleanROM.
I'm on CleanROM (1.0 still) with no apps to help with battery and i get .25% battery drain while idle (so thats 4 hours before i lose 1%) and 10-11% battery drain per 1:30 min movie with full brightness with WiFi on. How much better can the battery get on a stock battery? I bet you with Juice Defender you don't even get close to that simply because it actually has to run in the background while phone is idle to do it's job.

Without Juice Defender I'd lose 1% every hour and a half on standby. Since installing it, it has been much better.
