Given the recent run of battery posts, i thought i would join in. Yes you read it correctly; 98% after 5 hrs on battery. Thats with an up-time of 8:20, and an awake time of 1:51. During that time i checked and replied to a couple of emails(opened a photo attached) looked at pics in the gallery, and watched a 30 second video w/max volume three times. Also checked the weather several times to update the 5-day forecast.
So whats the secret? Dont open up any of the other screens after you reboot. Or, you can remove whatever you have on there and have only one active screen.
Heres the proof ( sorry about the crappy pic, all i had was my old Hero)
How do you do it can you explain a little better

Well, I don't have a picture, but my battery is down 2 bars on the screen you are showing...so roughly 80% I guess. I have up time showing 39:17:xx and awake time of 12:51:xx. I've looked at some pictures of my cat several times (had to put him to sleep yesterday due to a degenerative disc disease that finally damaged his spinal cord to where he couldn't walk anymore ) I did a lot of texting, e-mailing, some web surfing, and updating some programs from the market. I also talked on the phone for about an hour.
What did I do for this? Well, the only account sync I have is GMail, all the other crap is turned off. I have the LCD brightness locked at about 20% (auto brightness unchecked), I use WiFi whenever possible since 3G sucks the battery, and the only widget I have running is the HTC Sense weather/clock thing. It is set to update every 4 hours. Otherwise pretty basic stuff.
Uptime and awake time don't mean anything in regards to your claim. That just means, since you last rebooted your phone has been up for 8 hrs 20 min, etc. What you have to show to backup your claim is the time since unplugged...

Well, I don't really have to prove anything to you. We are not in court and I am not on trial. However, I can tell you I wake up every morning at 7:30 and unplug my phone which means, at the very least, the awake time is accurate. I didn't realize up time was only since last reboot. But still, sitting at 8/10 bars at 13 hours. If you don't believe it, then don't.

OK, so its was on battery for 5 hours and I unplugged it at that time. Im not trying to brag, cause frankly the battery was pretty crappy for the first week. I believe the stand-by time on this phone is awesome, Im more concerned about how fast the battery drains once you start using it.

When you reboot your phone, the only active screen is the home screen. If you long-press the Home button, you will see the other six screens blank. I left the other screens the way they came from the factory and found out that if you even look at them once, they seem to remain active even if they are not being updated.
I was charging my phone before I went to bed, and waking up with 95% (yes I minimized all the background updates). Then I would drive to work with BT on and it would go to 93%. 12 hours later, after two text messages and two voice mails, Im at 70%. Sure my up time was 19 hrs, but my awake time was 40 minutes max. So basically you need to keep everything but the essentials off your screens. This is my experience, as im sure there are people out there on 4G 8 hrs a day who come home with 50%+ on their phone.
Can I put apps on those screens so basically no widgets on any screen but the home

You don't have GPS enabled. That's cheating.
3G (or WiFI, 4G enabled) GPS, auto sync, backlighting, widgets, exchange, twitter, facebook, live wallpaper, all the reasons we bought the phone?! Those should be running at all times. (Otherwise, what exactly is the point? Srsly?)
If the battery life is still 3 hours then I am expecting a phone that hasn't and won't be built for 20 years.

I think we use our phones very differently. I like those features but I don't have them on all the time. I use the GPS when I need to use a GPS. I look at FB or Twitter when I have time to look at them. Live wallpaper, while cute, doesn't do much for me. Exchange and Gmail push is about all I use regularly.

I get about the same when I'm working a 10-14. That's with checking exchange email, background sync and data on, sending texts on a normal basis, brightness about 30-40%, checking fb, etc etc. Battery doesn't drain much at all for me while it's sleeping which is great when I'm working these shifts and don't care to bring a charger.
Using GPS with location on and Sprint Navigation will drain that beast though, but that's expected.

Damn your finely worded post. Now I feel the sudden urge to re-evaluate my obsession with live wallpapers so I don't feel like a lame kid that likes something "cute"

I had a epic 4g with extended battery 3500 mah and I would constantly use the phone even while at work.. At the end of the day my battery would be at 50%. On my evo 3d I use the phone even more now because its new and my battery would still be 50 % at the end of the day.
Fairly impressed
Doesnt the GPS only draw power if an app is actually using it at the time? So does it matter if you leave it on
Im pretty sure that if you leave your GPS on it will be put into "stand-by" mode, which in effect draws power. I could be wrong tho

that aint proof at all
use a program like battery status, that'll actually tell us how long its been since it was off the charger
but even from this, shows your phone doing a lot of sleeping
we'd be more impressed with a lot of battery left after actually USING the phone
I shut everything off that im not using. Only time my battery life sucks is when Im at work and get very low signal. That drains the crap out of the battery.
Plus I use Juice Defender, seems to provide some improvement.
After being unplugged and having used it as I described, after 20 hours I still had 68% of my battery charge. I don't have juice defender, but I made the adjustments I mentioned and the one I forgot to mention is I also turned off location services.
So far I am pretty happy with the battery life, but I also remember with the Epic I had amazing battery life for a month or so and then it was more like what is "average" for that phone. I'm no scientist, but I would guess that brand new lithium batteries do a little better and then when the chemicals start breaking down you lose that "little extra."
Sorry, I guess I should have included two pics. I do have battery status and it showed 5:05 since off the charger. I chose to post the other pic since I thought it meant more in terms of use. Sure it doesn't tell you how I was using it, just that it want sleeping for half of that time. Im not trying to impress anyone, i just thought it was a huge improvement from the past week where 5 hours off charger showed 70% battery left with only 40 minutes of up time (which resulted form a couple of VM and texts). So my point was along the lines of; more use, but huge improvement in battery consumption.

20hours, and almost 70% left?
i say super BS
because you know at that rate you can go almost 3 days with no charge right?
i know the evo 3d battery has bout 150 more mah then the 4G, but c'mon son
I just received my Rezound new yesterday, downloaded some apps from the market, and set everything up for normal use today. I got it off the charger this morning around 7:30am at 100% and its dead at 4:30pm. I would consider my use light today as I only used the web for maybe 10 minutes. I mostly did things like add contact shortcuts to my home screens and move icons around, and download maybe 2 new apps.
I came from a Droid 2 which got pretty awesome battery life running Liberty 3 and I'm wondering if my usage time is normal.
Total Time 8h 22m 33s
Display 80% (Time on 2h 45m)
Call Stand 5%
Phone Idle (Time on 5h 37m)
Android System 3%
Dolphin Browser 2%
Android OS 2%
Wi-Fi 2% (Time on 1h 38m)(I don't believe I was connected to any networks though)
Drop box 2%
The screen is what kills it along with LTE. If your screen was on for 2:45 that is why. The display sucks battery on this phone.
Thanks for the reply, I figured that was the case, but I still thought I would have gotten a little longer. I hope a custom ROM will help some with the battery life.
I am on stock rooted and don't really have battery issues. Typically I get 12-14 hours which by then I have easy access to power. If it is going to be a long day, I use the extended battery. It is not uncommon to still have charge left going into late at night.
I have the screen less than a third of the way on the selector and have Auto brightness turned off. Screen timeout is set to 1m but when I set the phone down, I have a widget called ScreenOff that I click to blank the screen. Primary reason for doing that is so I don't accidentally enter some app, but a secondary is that it turns off the screen before it would normally timeout.
When I am at home or at work, I use WiFi almost 100% of the time which due to strong WiFi signals there, (for me) uses less battery power than LTE.
Otherwise, I have LTE on.
Right now today, I am about 50% with 9h 12m of use. I fully charge nightly with the AC charger on my night stand so when I get up it is 100%.
I have an extended battery, but normally use the stock battery unless I know I am going to be away from the office for long periods of time.
I am not much of a game player, but I do watch short videos from time to time. I have streamed music, but don't normally. I get 10-20 calls a day typically and use my browser on a regular basis (reddit as well).
The camera is Awesome!
Unless your display was on max brightness and you were streaming HD movies. That's bad battery life. I get 2 times that even with autobrightness, maybe your battery isn't broken in yet
A good measure is 30minutes display time per 10%, and 1% per hour with 3G and normal sync scheduling... If your apps sync ever 15 minutes that will kill it, and 4G should kill it a little more than just 3G... Minor fluctuations are still OK, but you shouldn't have 15 minutes per 10% unless everything is basically on full blast
My battery life using the setup in my sig is usually very good.
I can easily make it through a normal workday listening to mp3s from my card/texting etc using the standard battery. My screen is set to 30%, screen timeout to 30 seconds.
I do like to stream audio however using iheart radio or Sirius radio online. If I do that, I'm lucky if I make it 4 hours on the standard battery (without ever turning the screen on) When I am going to do that, I use the extended battery and keep a 2nd one in my pocket. I have two external chargers I use so I always have spare fully charged batts.
I actually prefer the feel/weight of the phone with the extended battery and the HTCPedia cutout hard rubber case.. That gives me a better grip on the phone and I barely notice the weight difference when it is in a Jean pocket.
I guess it just depends on the actual phone itself. My phone charges everynight. I pull it off the charger at 6 am and by 10am the battery is dead. I have 3 batterys, and a wall charger that I carry around. I don't consider myself a heavy user either. No music or videos. Only text, gtalk, gmail and a phone phone calls that last a few min each. I only have google and exchage set to push. My 2 yahoo accts sync every 4 hours. I do have fecebook as well. Screen is very dim. This was all using rooted cleanrom.
I am now back to bone stock, with a CLNR phone that just arrived yesterday (due to connection problems with my computer) So maybe a stock rom unrooted will make a difference. Heres hoping!
Sad.....great phone, I love it!

This. I was playing "draw something " with friends today at work and even with a fully charged extended battery it only lasted about 3.5 hours with the backlight at 100% and oc'd to 1.7 GHz. But that was constant usage for those three hours.

Diff. Roms equal diff results for me. All of the ICS roms I've tried all keep my phone up time and awake time the same. Is anyone else having this issue? Due to this, I typically end up getting around 5 hours of life even if I leave my phone off for the duration of that time. It's annoying because I really want to stay on ICS but get double the battery life out of the GB Roms.

On Scotts CleanRom 3.6, with fairly heavy usage (hour of solitaire, hour of browsing xda, texting, 30 minutes of phone calls) I can get about 10 hours before needing a charge again. Before I updated to 3.6, which has the 3.8v battery fix, I could only get about 5 or 6 hours of similar usage. I don't recall if prior versions had my awake and up times the same, but I haven't noticed it recently.

I take it you don't stream audio like I do??
I just got my Rezound yesterday, and have noticed a surprisingly poor battery life. I did all my setup yesterday, and fully charged the battery over night. After unplugging it this morning, I listened to music off the sd card for about 45 min, browsed the net for about another 45, then stopped using it for a while. I noticed the battery was about halfway through, so I plugged it in to my car charger and did some more Internet stuff. However, after checking the battery info, I realized that even plugged in to the car charger it was consuming more power than it was taking in. I finally had to turn it completely off and let it charge to get the battery from yellow back to green.
This is the same charger I used for my Droid X, so I know that it is working...

I've been running BAMF ICS v0.9 for a few days, and the other versions before that. I get 12-14 hours with 4G on, and 20-23 with 4G off....I keep the screen on 40% brightness
Watch your clock speeds if you are on ICS. They constantly Max out, both cores. That's where your battery life is going.
Sometimes data flickers for me on random days, that's the only thing that wears my battery down fast. But I can still go through the day have 40ish percent left. If it doesn't flicker I can go through through day with about 50% left. And if in on Wi-Fi most of the time I have nore than that left over. And that's with using the phone for a couple of hours with the display on.
Trying ineffabilis with DSBs 1.1.3 kernel and undervolt it some
for me, battery life killers can be streaming audio (sirius xm or espn radio) and definitely jelly wars. Phone will die on extended battery in about 4 hours of continuous play.
Otherwise, normal usage, I get 10-16 hours of use on my extended battery before swapping it out (use 2 extended batteries).
4g definitely runs the phone hotter than wifi (about 20 degrees hotter for me)
The only time my phone gets around 95 degrees is if it's on a charger and I'm watching a movie, and it takes about an hour for it to feel warm, which could even be caused from me holding it the whole time. 4G doesn't get my phone any hotter than 3G Or Wi-Fi. Guess every phone is different though. least we get signal xD

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

7-3 is 8 hours
exactly how much screen on time do you have by the time its at 85% ? because i mean, it can go on standy for days with nothing on

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

Complete nonsense. https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT
Hi everyone, I'm relatively new to using android devices, i've played with some of the devices my friends own as well as a tablet my brother owns but this is my first personal device.
Anyways, I've had the phone for around 3 days now? It's going great but I feel like the battery is draining a bit fast and I'm not sure if I'm "normal" by standards or if my phone is slightly problematic.
I've attached the two screen shots below
Man things I do on my phone are Gmail, Push email for work, browsing, WhatsApp, Gchat and occasionally music and maybe 20-30 minutes of video.
As you can see from the graph there were two very short moments where I was charging the battery as well due to transferring some files. Finally, I've had a chance to completely drain the battery once but haven't had a chance to do one of those long charges people talk about but have through multiple charging occasions gotten it to 100, although right when I unplug it it goes to 99%.
Thanks!
EDIT: My phone wakes up quite a lot I think because I quite a few work emails a day, around 80-100 in addition to another 20 or so gmail emails a day. Thanks.
I have my own problems about the battery life too. Specially on standby mode all turned off (wifi,sync,gps,data,etc) 93% when I sleep then when I woke up battery goes down to 80%
are you too experiencing this as well?
haven't tried that yet, I attributed my battery drain to email, could be another problem then.
Start with Better Battery Stats from the market and look for wakelocks .

There are a few posts on battery issues.
I too had battery issues and in my case it was a couple of things.
I put the screen onto auto brightness and put wifi onto off when phone asleep.
These 2 things fixed my totally. I know lots of other people are having issues and its neither of these things but these are what helped me.
I also got an app to stop apps starting up. There are a suprising amount of apps that start when your phone starts up that you dont need to be running.
I think having wifi on constantly and getting 19 hours out of a charge is darn good for android.

I have experienced this after about a week of use. I left the phone when it was 95% and after an hour in stand by, it drops to the 80 something mark, b/w 84-86% any more people who experienced this?

Same here. Drain is about 2.5% per hour on stand-by overnight.

Yup, I had WiFi on pretty much on at home and at work and it certain does chew through your battery! Started at 7am at 100%, back home by 8.30pm and at 20-30%. By 10-11pm, it's on charge again.
Usage is fairly average, x2 30 mins of music to and from work, emails on push, send and receive texts, a couple of calls here and there.
I didn't save snapshots of some tests I carried out, but I'll try to recreate the situations again and upload them.
It seems if you have your WiFi settings, Keep on during sleep to Always, it's constantly draining your battery, even if your handset is on standby. I've left mine to Never, but have found only a small improvement to battery life.
Attached is my current usage WITHOUT WiFi as much as possible, there are a few power spikes where I've had to use WiFi and to connect to PC to transfer some documents, download some Apps. Also I'm NOT at work for the last two days, so usage has drastically dropped. Loooking good at 2D 1H 50M, battery at 45%
You can see for most of the first day where I haven't used WiFi there is a slow, but steady drop, the first major drop was when I was playing a game on the way home, then it's steady again. The biggest drop was when I used WiFi to download the odd app or two, then I turned it off again.
Hope this helps the OP in answering some questions about finding out what is draining the battery.
The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

don't judge a phone's battery life until a week later.

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
