I've found a potential issue with my phone, and wanted to see if anybody else can duplicate the problem.
My settings/environment are 4G LTE with 4 bar signal strength, full time display off, Bluetooth on. Stock ROM, using Google home launcher.
If the screen auto brightness control is off, and brightness set at 100%, the battery life is atrocious when the screen is turned off and the phone is in my pocket (drains about .5% per minute). Phone gets really hot in the pocket after only a few minutes.
If the screen auto brightness control is off, and brightness set at 99% or less, the battery sleep life is fine/normal. Phone is cool to touch.
If screen auto brightness control is on, the battery sleep life is fine/normal. Phone is cool to touch.
I have this same issue where my phone is getting super hot when in my pocket. drain on battery is crazy bad. this only started yesterday after the update.
I do have the always on screen thing.
my brightness was set to 75%
I am now having to charge after only 8 hrs of use

any of you guys having problem with serious battery draining issue?
sometimes when i check my battery usage, it shows display is eating up most of my battery juice, it can go up as high as 80%!
I've always set my brightness to the dimmest, off auto-brightness, Standard screen mode
I even try to reboot my phone and the display is still draining my battery
Display is not draining your battery. Time up after a reboot/unplug from charger is the base for all those info.
In your case, up time is about 10 minutes. 58% display means your screen was on for about 6 minutes.
Reboot your phone before you sleep, and let the phone sleep. Next day, check how much is Display using. It will be very less.
It's a big screen...
Big screens use a lot of power...
I don't think there's anything to worry about here, got the same stuff going on.
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!
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

Normally overnight I lose 8-10% in battery power. However for the last 4nihhts I've lost 25-30%, looking at my stats the phone doesn't appear to be awake but all of a sudden it appears the drain increases
Please can someone advise
Thankd
if you switch off location and google search in location services you might get alot better battery life, it work for me, over night I would drop 10-20 % now its only 5%
turn off gps, wifi, 3g, lower brightness

phone was asleep and didnt wake
but the drain increased , then slowed
but wasnt woken
So mine phone was draining battery fast as expected with a few years old device and battery wear. I took it to a repair shop and had a new battery installed.
Now the phone has been draining just as fast as the old battery which caused me concern as I should have seen some noticeable improvement.
Well it turns out when my phone gets to 5 percent the screen will dim which is the norm. HOWEVER I can move the brightness slider back up and my phone will go to 1% and just stay there.
I am able to play Youtube videos at full brightness while sitting at 1% battery for almost 2 hours straight before the phone finally dies and shuts off.
Is there a special way to recalibrate this battery as im guessing something is waaaaay off with the calibration?
"Stock - non rooted phone"
You just have to recalliberate your battery percentage
