Are you guys seeing a 1% drop a minute when you are using your phone?
I'm experiencing sudden drain after the update as well and I've tried everything from freezing VZ location to factory restores without any success. It seems the majority of drain is the result of the display.. Here's what I did to try and determine that.
Turned on airplane mode
Lowered display to the lowest setting possible
Set the screen timeout to 10 mins and left the screen on
On average my phone was losing 1% of battery a minute and the same was true when I disabled airplane mode. If the display on the phone was shutoff I was averaging about 1% an hr (in airplane mode) so I'm thinking this is related to the display.
Are you guys seeing a 1% drop a minute when you are using your phone? Any help would be greatly appreciated.

Are you talking streaming, idling, phone calls, data ? guess you need to define use a little bit. Even prior to the OTA , on stock battery while surfing the internet my phone I would drop almost that fast. I bought the extended battery and it was much better. After the OTA, I got an otterbox case and went back to stock battery and it still drains fast while surfing internet, but Idling or sitting in my pocket no drain.
Doing nothing at all. I just changed the screen timeout to 10 mins and left the screen on sitting at my desk, doing nothing. I was in airplane mode so no streaming or anything was taking place... If I turn the screen off I have very minimal drain.
I'm just trying to gauge whether or not having the screen on (doing nothing) and draining 1% a minute is realistic. At this rate my battery would only last a little under 2hrs.. I might believe that if I were streaming movies, phone was on, 3/4G on, etc. but in airplane mode none of that was happening.

This looks like it's a specific problem to your phone. I've never had that jurastic of a battery drain on my Rezound, even while surfing the web, playing games, listening to music, etc. If I were you I'd go to the VZW store and talk to one of the Verizon reps about it. Hope I helped!

It is the same for me. My screen destroys the battery. It can idle forever... but it does drop maybe 0.5-0.75%/minute for me.
I'm going to have to get an extended battery sooner than later. Screen destroys my battery. Just texting and a little bit of the XDA app and my battery will go from 95% to 20% in like 4 hours.
My phone currently has had the screen on for an hour total this charge. 15 hours on battery, 43% battery left. Screen used 38% battery having been on for an hour.

Definitely not a 1% drain per minute here. I was using netflix while riding the train to work(auto brightness) and dropped about 10% in 20 minutes.
The more shocking part is that I plugged in my newtrent external battery charger and still dropped 4% over 30 minutes(obviously much preferrable to 10%+ but when charging you would think you'd break even at least).
Yeah my screen takes up a great % of my battery life too, watching videos on youtube and using Navigation kills my phone pretty fast.
Thanks for the feedback.. New Phone
All,
Thanks for the feedback.. I went by VZW and got a replacement phone which is currently working out much better.
Thanks again!

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem
With very light usage, I've managed to get my Evo3D to last just shy of 2 and a half days. When actually using it, it's been a bit hit or miss, some days it tanks pretty fast, other days it's done quite well. But one thing I have noticed is that sometimes, especially around the 35% range, it'll spontaneously drop 10-15% (it actually did 43% straight to 14% this afternoon). It's visible in the battery use graph as a sudden nearly vertical line. It's never happened when I had the screen on actually doing something, it just happens randomly after turning the display off. Has anyone else seen this? It's pretty confusing.
First thing is first....
Did you download spareparts and see what is consuming battery? In other words, check for a wake lock.
You have to give the battery time to get conditioned. It gets better the more you go through charging cycles. I'm at 75% after 8 hours of moderate usage and that's pretty consistent for me.

For the first week or 2, the phone has a hard time understanding how full the battery is. Try draining it down to 50% or so, and then resetting it. You'll probably see a sudden drop or rise in the battery%. Resetting it will force the issue, but it can also happen while the phone is on. That's pretty normal till the the phone "Learns" the battery.
It doesn't mean you suddenly used 15% of your battery, it would probably explode if you did that... it just means the phone re-calculated the battery's life and changed the number.
Your not alone as soon as mine hits 35 percent ill shut the screen off and here it beep at me and bang its at 14%. lol same as you.
Don't know if it will help you.
I had a similar issue as you, battery would get to around 30ish % I could turn the screen on check an email, set it down and bam 14%, and the low charge noise.
I wasn't trying to fix it, instead I was doing this http://forum.xda-developers.com/showthread.php?t=1153371
When I attempted this I had about 35ish percent battery left, following the directions my phone restarted when it came back up I got a 1% battery warning, then my phone went into emergency shut down. I thought something happened and I was going to have to return the phone. I powered it back up and it read 33%, from there on out my phone now drops a % at a time, and my battery life is as good as the other people who get phenomenal battery. I'm going on 48hours with light usage and still have 25% left. I've txt'd music, videos, nothing heavy.
Take it for what it's worth, I don't know what happened maybe the data reset, resets the battery calibration, I have no clue, all I know is what happened to my phone and the result.
So I have narrowed down why my battery dies even when I'm not using my phone...for some reason when I look at the stats under battery usage, the battery seems to be awake almost 60 to 70 percent of the time, EVEN when I'm not using the phone...my battery lasted a total of 15 hours...I made a 20 minute phone call and screen usage was 25 minutes on lowest settings....4g was on wifi was on...automatic background data was off...gps on....everything else was off....why is the phone waking when it is not being used???? any way to find out?

Have you tried restarting your phone and then tracking the battery usage?
Just my .02 here, I installed Earth HD live wallpaper and the phone went crazy. I keep it plugged into my laptop during the day and noticed that the battery was slowly draining instead of maintaining, not much only a couple of percent. Toward the end of the day I noticed the the battery charge was in the 50% range and dropping fast, you could see the go down so I did a reboot and the charge came back at 4%. So you may want to look at what you have installed and try removing apps that may cause issues. I removed the app and now no problems, I'm also using Beastmod.
Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

Thanks, I logged out already will report back after some time
I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?
try wiping battery stats in recovery with a full charge
Hey guys the more i use my note daily it seems I'm hating battery life already. I basically have all features turned off and the screen brightness at its lowest. my battery usage is saying about 2 hours and 45 mins of screen on time till completely dead over an 8 hour period. What's the usual you guys are seeing on this. For only actually using the phone for about 3 hours with no games or special notifications or refreshes. Wifi is off I'm under clocked to 1.1. The battery is atrocious. I know its not made for battery life but being it has a larger battery then any cell and a little smaller then the razr Maxx i expect a little more. Makes me think there is a problem.

A couple of things come to mind:
1) Have you checked CPU spy to make sure you're going into deep sleep? (are you aware of the bug with disconnecting the charger while the phone is sleeping?)
2) Are you in an area with LTE and WiFi most of the day? I know it's opposite of what we're used to, but we've learned that the WiFi radio actually uses far less power than the LTE radio. Just something to think about.
Just some thoughts.
When mine goes into deep sleep I loose 1% per hour (wifi off, data on). I agree you need to get CPU Spy to be sure yours is going to sleep. When the charge wakelock problem occurs I'll loose 3% per hour - that adds up to 1/3 of the total battery during a 12 hour day. The work-around so far is to make sure you wake the phone AND unlock it before unplugging it. Most people only seem to have a problem with non-stock chargers and charging from USB ports.
The single biggest battery user is the screen. I highly recommend using Screen Filter and setting up a Widget set to 75% to use indoors and during cloudy days (then another Widget set to 30% for dark rooms - and turn it completely off for full sun). LED screens use less energy the darker they are, which is why this helps. I go into it in detail here: http://forum.xda-developers.com/showthread.php?t=1544757
Then there is the overnight charging problem (not related to the issue in the first paragraph). Once the phone hits 100% it only trickle charges for a little while. You know when the trickle charge has ended because that's when the "unplug me" nag comes up if your phone is on, or the screen comes back on for a few seconds showing a full battery icon if the phone is off. Once this happens it stops charging - so if your battery was almost full the night before you could hit this stage by 12 or 1 am, then it will start to run down again so the next morning it will appear to discharge fairly rapidly. If your phone is heavily discharged the night before you might not hit this point until 3-4 am (or later if you are using a non-stock charger or USB port), so the battery really will be nearly full the next morning and it won't appear to discharge as fast. The only way to get around the problem is to boot in the morning and then leave it plugged in for 15-30 minutes, or if it is already on, unplug and then re-plug it. Either way it will re-start the charging process and top off properly. The stock charging algorithm is just too conservative IMO. It should cycle the trickle charge mode on and off for up to 8 hours to ensure overnight charges really give you a full battery the next day, and not a battery that is only 96% full. Right now it allows the battery to drain back to 95% before automatically starting the charge process over. So ironically the less you use your phone the day before the less battery you'll have the next day if you don't top it off.
I'm going into deep sleep immediately if i leave my phone off the charger over night prolly 6-8 hours I'll only lose maybe 3 percent at most with wifi on. My standby time is awesome its my on screen time that's the problem. I don't have lte available where i live yet. My phone is always at 98 percent max after charging. I did check out a screen filter before but do i seriously need for my 750 dollar phone to look like sh*t to make it through a day? I jumped from a 4s to here where i got at least 20 standby and 6 plus hours screen time before charging with medium auto brightness full notifications enabled. Granted it is a smaller screen but its also smaller battery with what i would think is more draining data features. I thought led screens were supposed to draw a lot less power? My basic reason for the post is wanting to know what everyone else was concluding from average use of screen time before needing a charge. 3 hours of screen time is like two movies and my phone is dead. What's the point of a big screen cell if i always need to charge it after light use every few hours. Its basically a tv at that point which is always plugged in.

Which is why I recommended Screen Filter. It doesn't make your screen look like crap, applying a light filter (like the 75% I recommended) just dims it down a little. It works along with the stock auto-brightness feature, too. Using this I get 4 hours of screen time with 15-16 hours total run time. Most people report 3-3 1/2 hours of screen time w/o using Screen Filter. You won't get 6 hours - count the number of pixels on your old phone compared to this one.
With no tweaks other than lowering the brightness I'm averaging right at 4hrs of screen time.

i get about 4-3 hours of screen time with my overall screen time ranging from 10-16 hours depending on what else im am doing.
i also have profiles set up to keep my cpu in check while in call or screen off. i keep my phone on 100% brightness ALL the time as well. so if i did choose to dim it i could probably squeeze more life out of it.
Ya I'm at 27 percent right now 13 hours on battery about 2 hours of screen time with screen filter at 64 percent the phone brightness all the way dim. I can't see 4 hours if i tried. I dunno what the hell is wrong. What roms are you guys running? Any refreshes on face book tango scramble with friends etc. i lost about 5 percent over night with everything on. I'm using go launcher and handcent sms mostly occasional Facebook checks and fancy weather widget i use system tuner on demand 192-1.5. with screen off on 192-718 max and call settings. I drop like a percent like every 2 mins it seems when the screen is on. Also I'm on unofficial alpha 2
