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.

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

Yes, but what's your battery status at the end of this average day? 20%? 30%? 10%?
+1 for an awesome battery!

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar
I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

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.

This happened to me since i first got the phone it has slowed down and now the phone can last through the day ever since at&t throttled me for this month goes without saying ill take it easy next month. so most likely if your in an lte area thats the problem

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
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.

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

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.

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.

So I started a new thread cos its kind of different to my other one. The last little niggle with my Prime seems to be the battery. I read the instructions for once and it said to charge it all up. So i charged it till it was green and then powered it up for the first time. So as the instructions say i need to break the battery in. At the moment i am getting about 5-6 hours. The pad is on balanced with auto brightness. Does this seem normal for new battery. I would hope to end up with 9-10 or are my expeditions too high?
From what I remember the instructions stated that for the first time you should leave the prime charging for 6 to 8 hours. I personally didn't follow this and I'm still getting pretty good battery life. My advice is to let the battery drain out and charge it to full again and leave it connected for at least a couple of hours. The battery should calibrate itself through a couple of charge/discharge cycles and get better over time. Forgot to add, I have my wifi set to turn off when screen goes off.
If you're on firmware .21 it may be due to wifi. Check your battery stats. I have great battery life but as soon as i turn wifi on and use it battery goes down waaay fast.
I hope the new firmware thats coming adresses that, because before .21 that wasnt the case.

People that didn't fully charge it up the first time for 6-8 hours, exactly what kind of life are you getting and could you please explain what things you are doing on it. I didn't charge it fully and it accidentally got turned on during its first charge.
Thanks,
If you are on .21 don't expect the battery to be near 8hrs while on wi-fi surfing/video/screen on/etc. I had it on .15 for 2-3 days while deciding if I wanted to root or not and it was near 8hrs wi-fi on. I'm also hoping for the next update to fix whatever they implemented in .21 that's causing a significant amount of drain.
I am on 4.0.3, is that the right one
Sorry, wi-fi is .22
Thr charging over night for 10 hours or whatever is nowadays just a Myth that came from the old NiCd batteries (It was true back in the day), new LiPo / NiMh batteries have no Memory Effect and the first charge is nowhere near as important as with old ones.
In fact is actually better not to stress the battery doing full discharges / charges cycles.
These batteries get to their full capacity after about 10 charging cycles.
So if you didnt not charge X hours for the first time, dont worry, yout battery ill work fine.
The only thing that should be pointed out is that if you use very often your battery, every 2 - 3 months is recommended to let the battery discharge to 0% and charge while off to 100%. If you dont use the battery often (always connected) then is better once every month. Thats to keep the internal chip from the battery calibrated.
Well atm i am draining it down to <10% then charging. Is it ok for these modern batteries to be left on charging past 100%?
Battery life still seems pretty poor after 3 0-100 ish charges. 1-2% seems to last less than 5 minutes when on the net on balanced mode and screen brightness mostly down.

Yes, once the batteries are at 100% they stop charging. You can have them 100000 hours connected.. and they wont go past 100%.
im on .21 and i get great battery life. i never cut my wifi off. its on 24/7. battery drainage will more so be dependent on display brightness and what you are doing. wifi is already a known, wifi on any device drains battery at a faster rate than wifi off. it takes power to make wifi work ya know..lol i can easily get 9-10hrs. + with my brightness set to less than 25% & wifi on all the time.
also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

Web surfing and gaming and WiFi are 3 major things in this tablet, what should we use it for then??
here are some battery saving tips!

That's what I'm saying. Everyone web browsing and gaming is different. Some web pages people visit might be loaded with flash content vs. Someone who visits a site with less flash content. The one with the loaded flash content will drain or use more battery than the other one. Same with gaming. I might like to play Dead Space or Shadowgun and you like to play hang man or some other simple game. The battery will drain faster with me playing the 3d graphic intensive games vs. The person who is playing simple or less graphical intense games.
Wifi is a must have and no way around that if you want to web surf. The amount of screen brightness, 3D gaming, and web surfing will influence how fast your battery drains. Wifi drains battery but not at a faster rate than those other things listed.
I think some people here expect to have brightness up to the Max with super ips+ on, gaming and web surfing all day and expect to get 10+ hours out of it. Lol. Its not happening. There are easily things you can check for and change to make you have better battery life. -
-First one being not to use auto brightness and don't have brightness higher than 25%. That's if you so concerned about making the battery last long.
-Second thing you can do is go into settings and change screen off display settings. I have mines set to 30 or even 15 secs. That means once 15 secs. Or 30 secs. Pass and I haven't touched the screen, the screen will cut off. That's a huge battery saver right there. Because my screen isn't on as long when its not in use.
-Third would be to go into settings and lower the frequency of sync settings. I don't need my email syncing every 5mins. Or my Facebook syncing every 5 mins or etc.. cut them down to maybe every hrs, or every 12 hours, or once a day. The best would be to sync when you open up the app instead of it doing it automatically in the background. Completely cut off sync to apps you never use. Constantly having things sync in the background is a major battery drainer when the screen is on or even while device is sleeping. If you put device to sleep and its always waking up to sync data, don't be surprised if battery drains at a faster rate during sleep or when device is awake.
-Fourth, cut of unneccessary sounds. Do you really need the keyboard or screen presses to make a sound when you press it? If so, don't be surprised your battery draining faster.
-Fifth, cut off that stupid vibration motor. Do you really need your tablet to vibrate when ever you press something on the screen or keyboard? Do you really need it to vibrate when your gaming? If so, don't be surprised your battery is draining faster then. Because everytime that vibrate motor goes off, it drains battery.
SIXTH, you can go into settings and have wifi cut off when device is asleep. Or you can go into Asus customized settings and have it cut off network activities when the screen is off or device is asleep.
All very easy steps people can take. Same thing as in saving gas in a car. There's things you can do or not do to make it last longer.

So I started a new thread cos its kind of different to my other one. The last little niggle with my Prime seems to be the battery. I read the instructions for once and it said to charge it all up. So i charged it till it was green and then powered it up for the first time. So as the instructions say i need to break the battery in. At the moment i am getting about 5-6 hours. The pad is on balanced with auto brightness. Does this seem normal for new battery. I would hope to end up with 9-10 or are my expeditions too high?

Its Def the firmware Asus should fix it soon hopefully

It does seem to be getting better though. I have had it on for over a day now and it is at 50%. Probably had a good 3ish hours of actual use. During the breaking in of the battery stage is it better to let it drain then fully charge or charge whenever I can?

im on .21 and i get great battery life. i never cut my wifi off. its on 24/7. battery drainage will more so be dependent on display brightness and what you are doing. wifi is already a known, wifi on any device drains battery at a faster rate than wifi off. it takes power to make wifi work ya know..lol i can easily get 9-10hrs. + with my brightness set to less than 25% & wifi on all the time.
also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

Well hopefully after a few charges I will make my way unto that region, I think it has climbed though to a closer to 6-6.5.
Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!
Read forum for more details.

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.
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.
