I switched to AT&T last week from T-Mobile to get the Note. Overall the AT&T service has been good and the Note is great! My only concern is battery drain in no signal areas.
Specifically, I went to a movie last weekend and the theater was in the basement and there was no signal. At the start of the movie I had about 95% battery but by the end my battery was dead. I'm guessing the battery drained because it was constantly searching for a signal.
Is this common for the Galaxy Note? Is it common for AT&T? I ask because my t-mobile phones never did this. I've been to this theater many times, always had no signal, never had any battery drain on any t-mobile phones (sensation, galaxy s 4g, hd2, my-touch).
FWIW, my Note was completely stock but was rooted. I've since flashed UCLE2 and noticed the same drain in low or no signal areas. I'm sure I'll get suggestions to turn airplane mode on, or something like that. While I appreciate those suggestions I'm trying to determine if this is common to the phone or AT&T. I don't think I should have to switch off data/radio anytime the signal is low for fear of my battery draining in 2 hours.
Thanks!
While the battery does drain more with no signal, due to scanning for a network, as long as there is a signal it should be comparable to full service. That's a constant signal mind you if it goes in and out it is scanning.
I work downtown in a brick building surrounded by high rises, i get 1 bar in my office, my battery lasts me an entire work day.
What I did, spend the money on extended battery
Yeah I know you think 2500 mAH should be pretty good, but isn't, just spend the money on extended battery. Am at 26 hours, with fairly hard use, on Mugen 5400 mAH and have 15% remaining. Does add some depth to it, but that is the price, daughter ordered me case that fits over extended battery can't wait till it gets here. If you are interested can post pics once the case is here so you have idea on overall look.
Would no signal cause that much more drain? In the theater there was no signal. I couldnt browse or make a call. If memory serves there was a circle with a line through it where the 4g symbol would normally be. Still seems like an excessive amount of drain.

Oh yeah, if it is constantly looking for signal, will suck a battery down in no time. Job has me go to places in the mid-west, my supervisor and I just know to put in airplane mode or turn off in certain places or we will have bricks due to quick battery drain.

Interesting. Is this something unique to AT&T's service? I never had this occur with tmous. Maybe I'm just lazy but having to track if I have a signal all the time for fear of my battery draining that fast doesn't seem right.

Not unique to AT&T, but once you figure out where you get no signal it becomes automatic reflex to go into airplane mode or turn off. Would assume since AT&Ts network coverage is larger than Tmobile would not occur as much.
just got one for me and bro.
i got no signal half a day during work and it keep searching for it.
by time i finished, lost about 5-10% most.

Wow. Big difference from what I saw. I think I'll need to go back to the theater now that I'm running UCLE2. I'll install CurrentWidget and see what is going on.
Maybe it was a fluke...hopefully cause I love this phone!

3 days in w/ my TBolt and VZW announces the Incredible 2 yesterday, releasing at the end of the month ...
Rumor has it that battery life will be much better than the TBolt, so is anyone returning their phone right now due to battery life or will there be an improvement once new ROMs are released? Is it worth the wait?
maybe it probably will never get any better. i would seriously maybe probably consider thinking about debating on planning on returning your phone.
i dont know what htc/verizon was thinking when they released this. i mean technology like this and i have to charge every day!! unbelievable!
i probably think inc 2 will maybe be better since its a 3g phone.

I like the TBolt... And not waiting on a rumor for the Dinc 2
Last I checked, the Dinc2 is a 3G-only device.
I haven't had any trouble with my Thunderbolt's battery life easily getting through a 8hr work day with plenty left over.
I'd say it's an almost certainty. There seems to be a problem/bug with the radio which makes it drain a lot of power in certain areas (my house seems relatively fine, but in town it's not ... maybe certain towers for some reason? No 4g in my area, so that's not it) when you have mobile data enabled. I'm currently at 78% battery with 13h 30m on the clock ... by turning off mobile data in the areas I've discovered where it decides to draw the obscene ~900mA (or some other fairly constant, very high number) when I encounter the "bug", I've managed to essentially make the battery life as long as anyone could expect.
For some reason, the radio will not admit to drawing practically 90% of your battery in the battery use menu.
So, I'm thinking future radio software/firmware updates can drastically improve battery life if they discover the cause.
Currently, without the area with the bug (I'm at my house) and screen off, I'm drawing 42-60mA on 3g radio and 40mA wifi. And areas with the bug, it's 700mA minimum with spikes often at 900mA and above.
Seriously, how long would you expect a laptop battery to last? These new smartphone are basically mini laptops. I'd be lucky to get 4 hours out of my laptop. My phone will make through the day with moderate use.
Just my 2 cents

Same here..
Bought a spare stock battery on launch day expecting the worst, but have yet to have to use it. I make it through the day with good use no problem. Today was even better after loading das BAMF 1.3 ROM w/ kernel, overclocked to 1.2GHz as well..
Mine has gotten better over time. Im sure with the next couple updates the battery life will get better. But if you dont care about lte or the bigger screen you might just want to get the incredible 2.
My battery has gotten better over the past week. It's tolerable now. It will make it through a day, which is all I really need.
It's never going to get good battery life though.. there's a lot of stuff packed into this phone and on top of that, the 1400 mah battery is already small for a device like this.

Last night I unplugged my phone at 430am. Went back to sleep woke up about 730 and battery was at 45% with WIFI on. Don't know what's going on. Some nights 8 hours with 4G on my phone won't even burn 10%. The WIFI thing is puzzling to me.
Can't say for certain, but I've heard gingerbread significantly improves battery life in most phones...
and rumour is, we will get gingerbread official in Q2. (unofficial via cm7 maybe sooner???)
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.

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.

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 read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?

Is this normal? I've had several android phones and this is the first time I'm seeing Cell Standby kill SO much battery.
I'm on stock rom with tibu frozen/removed bloated apps.
Same, it seems like cell standby time is around half of the battery usage. It's ridiculous, especially considering the screen is usually the battery drainer. I've heard that others have had this problem, and that, specifically, it was very prominent on the International Version. But I heard, however, that they supposedly fixed it for the US versions.
While I'm not sure about this, especially since many others, on other carriers, have also complained about the cell standby draining battery. If anyone has a clear answer, it'd be great.
Aside from the fact that so much battery seems to be lost due to cell standby, I am able to go around a day and a half with one battery, according to my "Battery Manager".

Same, it seems like cell standby time is around half of the battery usage. It's ridiculous, especially considering the screen is usually the battery drainer. I've heard that others have had this problem, and that, specifically, it was very prominent on the International Version. But I heard, however, that they supposedly fixed it for the US versions.
While I'm not sure about this, especially since many others, on other carriers, have also complained about the cell standby draining battery. If anyone has a clear answer, it'd be great.
Aside from the fact that so much battery seems to be lost due to cell standby, I am able to go around a day and a half with one battery, according to my "Battery Manager".

This has been posted multiple times BUT...the Cell Standby reporting is an error - it's not really taking that much battery it is reported wrong. I'm getting expected battery life even with Cell Standby being so high - just ignore it UNLESS you're getting abnormally low battery life.
The bug is ONLY with the "%" displayed by battery in stand by mode.
The fix won't improve the battery.
the real value of the "cell stand by" should be divided by 10
so, It's only a display error.

thanks, that makes a lot more sense. ill apply the fix so I can better understand what exactly is killing my battery.
I have been meaning to post in here about how great my battery life has been, especially after seeing all of the threads complaining about it. I have been going home after a 9 hour day with 70-80% and even with extreme use, I have had no issues.
That being said, today my battery drained inexplicably fast for no reason. I checked my background apps and closed a few, but the battery drain persisted, so I rebooted.
Anyone else having this issue or know what causes it? This is the first incident I have had in almost a week. The last app I launched before this happened was Inrix traffic. Battery life has been beautiful, otherwise.

That's the fix I use. I now call my 920's battery life non-deterministic. It's great, except when it's not. When it's not, even if it looks like it should be because nothing is running, a reboot fixes it. Until the next time.
I would be shocked if there weren't an OS update to fix whatever process is going rouge and running away with the battery. Because it's something in the OS. Or at least its something the user cannot remedy, short of taking off and nuking the site from space.
I've noticed this a lot too. I killed a whole load of background apps and the battery life got a lot better. Then it got much worse again.
I believe my main problem is that I live in a low signal area. So I drain the whole thing in about 10-11 hours, even when out working the majority of the day.
One thing I have found is that the radios in the handset are very badly shielded compared to my previous handsets. This does mean that I can hear when the phone is sending out signals/utilising the radios. It does this a lot, even when it does have signal. It must consume a massive amount of power.
I get roughly 5-6 hours or so. Charger I bought on Amazon no longer does the trick (it's one that plugs into the cigerette lighter in your car and two USB outs). I have to bring with me the power cord and an inverter to keep it charged up so it makes it through the day.
I've got NFC and Bluetooth turned off, Wi-Fi on and the phone set to 3G mode. I get pretty solid battery life out of it.
When I feel the back of the phone getting warm, I reboot and it's good for awhile. I too would be surprised if there isn't an OS update to fix this issue.

I am heaving same issue with battery. Phone worked fine first 10 days and it started to be warm on the top back. Life of the battery can not last a day and i am a heavy user.
As somebody mentioned in comment to turn off this and that- i don't think so. I did not buy phone to keep everything off on it.
If in airplane mode. had couple pictures and few other things, this is what you get out of your battery.

Excellent. I'll just keep my phone in Airplane mode all the time! What was I thinking, leaving the cell radio on?
I've just had 2 great days life out of mine. Off charge at 6am and currently sat at 58% at 4pm. I've been streaming a podcast from the internet via bluetooth for 90 minutes and I've been tethering too, as well as all the usual stuff, so it's not like it's been sat idle all day. I've even been using Nokia Drive to get to work this morning (I teach at many different schools) whilst streaming media off the web and bluetoothing it to the stereo and it's not hit it bad. Seems very power conservative where internet streaming and GPS is concerned.
I have battery level for WP8 installed and it has a graph so you can see when the battery level is dropping off. I've noticed solid battery drain from running the Audible app which continues after the app is closed. Rebooting solves this. I have been working in an area with excellent signal recently though, that may have made a big difference. I get 9-10mbps on HSPA at the moment. I do, of course, have NFC turned off.
Hopefully Portico will be here soon and solve some of these power problems.
