Why is phone "awake" so much?

So I just looked at my battery usage and notices that my phone has been "awake" for such a long time. I know I haven't used it much at all today. Anybody have an idea why this is?
I would upload the screenshot, but its telling me that the file has the wrong extension. ???

I have a huge battery drain (about 60%) by OS Android proccess even in the standby mode. I don't know what to do with this ****. From 100% to 0% it takes about 6 hours my phone dies in standby mode (with CM9 rom), with stock rom my phone lives in standby mode about 2-3 days.

Sounds like you have a rouge app(s). Download Better Battery Stats and CPU Spy. Read their respective threads to understand how to use them. There are threads where people will help you interpret the logs these provide.

I agree with dnorthington. I had the same then I realized that drawfree was draining my battery in a matter of hours...

Android OS only reports such high values in ICS because it includes screen on time.

Did you download better battery stats and CPU spy? Look in the ATT Galaxy S II thread. There's a pretty good known battery drain thread. My idle drain is less than 2% part hour. My deep sleep is over 95% when idle. Has to be a rogue app.

I charged mine and let it sit for 7 hours. With wifi set to always on, I get 11% drain overall, 92% deep sleep and 6% at 192.

Post your tips for battery life.

Most people in this forum are far more tech savy when it comes to cell phones.
Post your personal tips for battery conservation. Include specific apps if you'd like.

I don't worry about battery life, brightness all the way up, sync on, widgets on every screen, Wi-Fi always on. I usually get about 14 hours

I'm very conservative. WiFi off, data off when not using it, brightness depends, auto sync off, no battery sucking apps like facebook

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.
PS Facebook app SUCKS. Just bookmark the webpage and use that. Works better and doesn't ruin your phone.

Here how it looks like ! Lovin this screen on time..

I think it depends on how its configured. I've seen it eat the battery but also not use it much at all. Been a bit since I messed with it though so don't remember what settings made the difference.

i have betterbatterystats too but have no idea what the wakelocks affect and how to get rid of them.

Post a screen shot and I'll tell ya what could be happening.

You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).

I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic

4500mah stock
Only 58% of battery
Sent from my SGH-T999 using xda premium

I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried. Even with GPS, WIFI, and screen at full brightness I can make it through the entire day with 30-40% battery left. If your looking for a rom-based solution to your battery life, check it out!

Is my battery life normal?

Hi All I just got the Galaxy Note 2 like a month ago and I've been loving it the only thing that I've been question mean if the battery life right now I'm getting like 4 hours of screen time and that's basically what I use to get with my Galaxy Nexus.
I just wonder if this is normal because I hear people a lot saying that they get several days of battery in for me I just feel like I have to charge it every day I also been monitoring the apps that I have and the background usage of them and nothing seems to be draining it.
I'm using android HD 6.0 with Perseus kernel

On really heavy use, that is pretty normal. But for normal use or moderate ones, certainly not. Based on your screenshots, you have a lot of wakelocks, these are the number 1 culprits for unexpected battery drain, go get better battery stats and use the phone exactly as how you used it when you took those screenshots, then after a day or two, checkout better battery stats and find which app was actually causing those wakelocks.

another battery drain question from screen

So late last week I installed liquid smooth and it was working awesome! was seeing -2.3% an hour on my battery drain. but as of two days ago, i'm getting a low of -13% drain an hour and sometimes all the way up to -38% an hour! The charge rate has even fallen from 24% an hour down to a cahrge rate of 10% an hour.
I think the culprit is the screen because it shows at >50% on the battery monitor and in the app "battery drain"
I've honestly searched and searched but can't find a solution to this. How can I pinpoint why my screen is using so much battery (brightness is on auto) even when my phone is in standby most of the day?

Same problem mate, mine is almost 80% drain by screen only..I replaced new battery also in RMA but its also not worked, maybe new update of android fix the problem..mine currently is 4.2.2 JB on nexus 7

Battery life.

I've got to say, battery life is pretty bad with this phone. I bought it brand new yesterday so not sure if it needs to condition itself or not but I came from a LG G2 which has a 3000mah battery, which is slightly smaller than this but battery life was far better. Granted the screen was slightly smaller but still. Is there any Roms that improve battery life but still relatively stock?
Sent from my SM-N900T using xda premium

Have you disabled all the smart scroll and air gesture stuff? Its useless and hogs battery life. Auto brightness and juicedefender and I can rock it for 2 or 3 days straight.

How long is it lasting for you?
Sent from my SM-N900T using Tapatalk 2

Ya, this sounds bizarre.. I've found this battery to be amazing. How long is it lasting? I've had mine for less than a week and I've used it heavily everyday. I have not even had to worry about charging during the day. 24 hours no problem.

Same here. The first week it was lasting all day but with only 3 hours of screen on time. After some tweaking, I'm currently getting still 20ish hours with 5-6 hours screen on time.
Sent from my SM-N900T using Tapatalk 2

I just don't get it. A lady I know has the sprint variant and I looked at her settings and she had 15 and a half hours off the charger with 5.5 hours screen on and had gps and all the air features on as she's not tech smart so her phone was like out of the box and her brightness was up. I have a custom ROM with GPS, NFC and all the air gesture **** off with the screen at like 35% brightness and I get no where near that.

Also what tweaks did you make? I should rephrase that I get good battery life with the screen off, it lasts all day but screen on time is horrible.
In this pics android os and google play services is destroying battery. The screen time was only like 1 hour and 15 minutes at that time.

I downloaded that we'll see how it works. Like I said the battery easily last 24 hours with medium to little use but it dies fast while using the screen on, I'm seeing others with everything on like GPS, NFC and al the touchwiz things with their brightness up getting far better on screen time than me with everything off and brightness dimmed

Any suggestions appreciated. Anyone try an extended battery yet ?

Stock rooted, I was getting about 24 hours per charge with about 6-8 hours of screen time.
I just recently installed Faux123's kernel and enabled the Intelliplug and Intellithermal drivers, now I'm getting about 60 hours per charge.

Well my actual battery just must not of been created equal with other phones because after tweaks I'm getting better battery life but only about 5 hours screen time and I have everything turned off with screen on 35% so I don't know :/. I'll check that kernel out.

Well if that is the case your battery life isn't terrible. 24h with 5h SOT and 24% life isn't bad at all. Its not great but it is far from terrible.

I'm just using the stock ROM, rooted with the Kingo Root app. Installed TWRP and then Faux Kernel (hltetmo-faux123-003u)
Be warned, TWRP did trip the Knox counter to 0x1. I had to install Knox Disabler so it would stop complaining.
I was getting about 24 hours per charge, until remembered about the FauxClock app and enabled the Intelliplug driver and Intellithermal manager. About this time, I also installed Advanced Task Killer after going without it for a few years.
Screen brightness is on auto, WiFi and mobile data are both on constantly. I have not had to make many calls though, so I'm not sure how this may affect battery life...
So far, I haven't noticed any decrease in performance. Right now I've been on battery for 30 hours and I have 45% left.

Because of adjustments... Custom ROM and kernel, Screen is at 35%, gps and all location services off, NFC off, all the phones extras like air gestures multi window etc are off, I use greenify to freeze apps and I have most Google syncs off and I'm only able to achieve this. I know a lady who knows nothing about phones and has everything/feature on the phone turned on with full brightness and gets 15.5 off charge with 5.5 screen on time by the time she's at 30%. I don't get it.
Edit- I should note I made this post while stock. Because I heard phenomenal things about this phones battery and was quite disappointed.

Signal strength and the binning of your CPU could be differentiating factor. Reading into other people's experience too much can lead to disappointment.
