[Q] Transformer Prime Battery Issues - Asus Eee Pad Transformer Prime

[Q] Transformer Prime Battery Issues - Asus Eee Pad Transformer Prime

Sorry if this has done the rounds, but im new to forumn and none of the posts seem to have all my symtpoms.
I bought a few weeks ago a tf201. everything is great, bar two points.
1) - battery life is emmense when docked on the keyboard and in use, and undocked. BUT when i leave it docked it just seems to refuse to go to sleep and manages to chew up just about all the battery overnight. from the battery monitor in settings the wifi and screen stay on overnight so it loose 5-10% or so an hour.. not great
2) not sure if this is related to the above, but again only happens when docked. if it does go to sleep (i think). when i come to wake it, nothing happens. in the end i have to press the power and volume buttons to reset it, then it wakes back up again. interestingly when its dones this it doesnt appear to have lost much battery charge.
So it seems that either it doesnt want to sleep, or if it sleeps, it sleeps a little too much.
im running the latest OTA ICS update as of last week and havent got that much installed widget wise etc. Ive been pouring over the forums for people with similar issues and the nearest i can find is people recomending using flight mode apps to keep the tablet from completely sleeping. this sort of works but the batteries then need charging every 2-3 days, which is better than daily but not great.
any pearls of wisdom as this for me is ruining an otherwise great device...

Maybe try setting WiFi on sleep to never under the advanced WiFi settings?

Email Accounts set to "push"
Email clients connecting to Exchange usually have a "push" option that continuously syncs with the mail server. Some of them (like Touch down which is what I use) allow you to set off work times when it won't be polling the server so I set it not to poll between 10:00 PM and 6:00 AM.
Also, look at the accounts and sync area in the settings and see what other stuff is being synced. I had no idea until I looked just now how much stuff is getting synced under my gmail account. It's not just mail and calendars like I thought but also a long list of other things.
Then, looking under "Backup and Restore" in the settings, I'm seeing that it's doing a "backup app data, wifi passwords, and other data to google servers". I'm assuming that means all my mail etc. When I first set up the tablet a couple of days ago I noticed that all the wifi connections from my Droid 3 showed up so that was the first time I realized that my phone must be doing this too...
That's a security issue in that by my employer's rules, sensitive company data isn't supposed to be stored on other people's servers so my exchange data really should not be backed up to google. And it doesn't make any sense to do that anyway. If one of my devices dies and gets replaced, when I configure the account on the new device, all the data will sync from the mail server anyway.
The point being that I'm discovering that there is a huge amount of stuff being synced from my android devices that I didn't even realize. That could be bogging down the network (particularly if on a connection that's slow to begin with) and also causing battery drain.
I'm experimenting with turning a lot of stuff off that I don't figure I need - both for the phone and the tablet - to see what difference it makes.

The exchange DATA, meaning your actual mail does not get backed up explicitly anywhere with vanilla Asus/Google ICS Firmware. What it backs up is account settings, and the options you select. Backing up all your mail would be awesome (under the right circumstances, such as when you need that backed up, and some apps will do so, but generally for a fee.
OP, for battery concerns, make sure that in settings, Asus Customized setting that "Mobile Dock Battery Saving and "Disconnect network during sleep are both selected. The latter option stops most or all synching when sleeping.
It sounds like you are experiencing SOD (Sleep of Death) not quite as horrible as it sounds, but if you have to push power button and or/ Power + Volume for 8-10 seconds to get it bac, does it then vibrate and reboot, or just come back to the Homescreen imediately? If it's the first one, look up SOD. I have had only ONE event since .28 rolled, and before that perhaps a dozen on .21, and NONE before that so it's due to SOME recent changes to firmware, at least in my case. Interestingly, I was able to stop it on .21 by disabling the same option we have been discussing. The two battery savers in Asus customized, and WiFi, Advanced: "Keep WiFi on during sleep" (You have to hit the "three dot" menu and choose advanced from WiFi Settings.
Anyway keep us posted, and let me know if you have SOD, or just a deep sleep - if you REALLY want to know how often and how long your tablet spends in deep sleep get CPU Spy (no root require, I believe) and after several hours, it will let you know what the CPU has been doing, for what percent of that time. it is an AWESOME way to determine how much deep sleep you are experiencing with the device.

My battery is not really satisfying.. though i uses only 15% brightness, it sucks up my battery like hell... 10% decrease in an hour... is this normal?

10% in one hour of using?? so 10 hours???
I guess you should be more than satisfied........:good:

possible win
Many thanks for the suggestions.
I think i was get the dreaded sleep of death as when it slept to 'wake' it i had to reboot it.
Ive run through all the suggestions here + a few suggestions from the forumns, setting wifi to never, adjusting the dock battery usage, checking my sync options. In sheer frustration i removed all widgets and removed a shed load of apps (both pre-installed and ones that i had installed) installed cpu spy and tested. interesting that it appears to be ok now. charged the dock and transformer up on firday night and its still got juice today, all be it that dock is nearly dead and the transformer has 80%+ thats with 2-3hrs use every day and obviously sleeping...
one thing i did note. when it was docked before and 'sleeping' in the transformer battery was low it would charge for long period when it was sleeping? it doesnt seem to do that now. if the transformer battery is low and i sleep it. the power \ charge light stays on for 10-15 mnutes then goes off.. so def looks like something was keepign it awake.

go to settings/asus customized settings and scroll down to battery saving and check the two power saving settings :good:

[Q] Synch interval with gmail?

So I tried to get my work to get me a blackberry because I need to check my work email when I am not there at nights, weekends, etc. They saw I had a thunderbolt but I tried explaining how the battery wouldn't last. Well that wasn't good enough so today I synched my works email (corporate gmail account) to my phone and I am getting the push notifications just like I wanted, and the battery is terrible just as I said it would be. Is there any way to adjust how often it checks for new mail to push notifications through? I feel like there has to be some way but I searched and found nothing for the thunderbolt. Any help is appreciated.
Thanks

Not sure if this would work for you, but you could go into your accounts & sync setting and uncheck the autoupdate for your google business account (since I don't have one, not sure if it will allow you separate out google accounts). Then only go in and manually sync it when you need it?

The only thing with that is I have to manually sync which defeats the purpose of it

How much mail do you actually get pushed?
I get quite a bit of mail to my regular google account because I've tied all my other accounts to my google account and I don't have any real issue with extreme battery drain?
I had an android since the G1 first came out and with each successive phone I've gotten, I've never noticed that mail is a real big battery drain on any of them.

I would say 15-20 mails a day. However one of our clients is west coast based so I tend to get a lot after I leave work. This is definitely a battery killer by multiple hours. I'm going to try my damndest to get a blackberry and show them how awful it is but I need something in the mean time to get me through the day. My phone didn't last 9-6 today

I can't believe something as simple as an interval adjustment isn't built into the gmail app. I searched all over and several people have asked this but there is never a solution. I wonder if I could use another email app that is adjustable instead of the official gmail app.

The easiest solution is to check one of the apps, such as Juice Defender, that can turn off your network connection when not in use. You can set them to periodically enable them to turn data back on to allow things like emails to come through.
And GMail push notifications act just like Blackberry-style push notifications of email. It isn't constantly checking the server for new emails. It gets notified only when new emails arrive. Something else is likely causing your battery problems, not the push notifications. I'd check some of the battery threads around for other tips to increase battery life before making any major changes.

I've never heard of email being the culprit to any battery problems, so you might want to see if there are some rogue apps you have that are causing this battery drain.
As for email, I use Tasker. I have a profile that turns auto-sync on at 6:15 AM and every three hours after that at a quarter past, then I have a profile that turns auto-sync off at 6:17 AM and every three hours, so I only get email at a quarter past, every three hours
Not sure how elegant of a solution this is for you as you work for a company and might have some emails that you need to respond to ASAP.

I use Tasker as well, with it checking only between 6:30am - midnight. However, I check mine every 20 minutes normally. If they need to get in touch with me faster than that, they should have called in the first place. I played with Juice Defender prior to discovering Tasker though, and it is much easier to set up.(Just not nearly as powerful as Tasker, which I love playing with)

Push is more efficient than interval, that is why you don't see interval adjustments.

Well as others have said, I don't think it's the emails causing your issues. I get way more emails than that in a day and my phone comes off charger around 5am and doesn't usually get back on a charger until at least 9pm or later. I'm not saying I still have half a charge left, but I also don't have my phone yelling at me to plug it in either because it's low.

Hmm good to know about how those push notifications work. I guess it's just a coincidence that when I synched my email a couple days ago that I noticed the battery went noticeably down. I might try out tasker though. Thanks

It could have been also your signal strength when you were trying to sync that could have caused a bigger drain.
If you had a weak signal, your phone would have been trying to "juice" up the connection to keep you connected resulting in a larger than normal battery drain.
Just a thought.

this is true since I moved from central jersey (manalapan) to North Jersey (wallington) I am now in 4g constantly and maybe I should look into switching to 3g for a bit.

JuiceDefender Ultimate Questions?

For those familiar with this app. I believe it is definitely helping battery life, but at some costs I'm not sure I like. For example it seems when I'm outdoors it disables data? Even at the balanced setting? Just by looking at the log I believe thats what I'm seeing. If it is disabling data, then that would mean no emails etc correct? Or does it periodic checks on its own and enables when necessary even when screen is off? Hope someone can explain.

With the default settings:
-it will periodically enable data for a short amount of time for all things like emails to get pushed through (under the schedule section)
-it will enable data when the screen is on, only after you unlock it. (that way you can check the time on your phone without having data enabled
With my settings (JD ultimate)
-the data will remain ON when certain apps are running in the background w/ the screen off (Pandora, Google Music, Google Maps)
-data will remain on when it's plugged into the wall (charging via usb is still the same)
-when apps request data (1kb/5s), data will be turned on for 15 seconds (more if needed)
-if connected to WiFi, data will be disabled.
-when on data, WiFi is disabled
-if there is an incoming MMS, data will be enabled
-My Juice Defender has also been trained to use cell towers (NOT GPS) to get my location. If i'm near a place where I have connected to WiFi before, it will turn on WiFi
I get 68% more battery out of my phone w/ this app. Just keep in mind this helps battery during standby (screen off) and not much else.
But when it's configured right, it's an easy battery boost that won't get in your way in terms of use.

So even with default settings, there is a schedule section? I didnt see that option.
I'm assuming you are using customize?
UPDATE: I did not see the controls and schedule tab even after selecting advanced. I had to kill the Juicedefender ultimate app and restart. Now when I check advanced, the tabs appear. Wow there are so many customizations. As said below, I would not mind a step by step set up to get best battery life results on note from you or others. Thanks.

I would be interested in a step by step of your setup. I love JD Ultimate and I get better battery but I know it could be even better. Your setup sounds ideal.
Can you give us a walk through?

Agreed me too . So far on default juicedefender has really extended my battery life.

Juice Defender Setup Guide - Ultimate only
First thing's first. Download the apps. You will need the regular app and then the DJ ultimate license.
Launch Juice Defender Ultimate.
Under the STATUS tab. There is a section that says "Profile". Select "advanced" and then hit confirm. This unlocks a majority of the settings for the app and allows you to set custom triggers, app exceptions, and much more!
As you can see at the top, there should be a few more tabs that popped up.
Go to the "Schedules" tab
This section is what allows data to be periodically turned on so you can receive things like emails and and PUSH notifications. I have me enabled and set to a 30 minute frequency.
Going on down, we see the Night section. Set it to the hours that you normally sleep. This is disabling periodic data. This is good for 2 reasons: If you don't want things like email notifications waking up, and if your phone is not plugged in and you want to slow the battery drain of your phone.
I don't change anything else on this tab. Adaptive start for Night mode I leave on default (+2h max for start, end -1h max). If there is a period of data where you need instant connectivity for things like emails, then you can enable PEAK hours. (disables JD controls for a defined amount of time)
Triggers tab - this is the fun stuff.
Keep "battery" enabled. This ignores scheduled data on periods if your battery reaches a certain point.
Here is how I think about it. If you come home and you usually have about 40% of a charge, then set the threshold to 35%. By having it set to a point right below the average use like that, it's great because it won't get in your way as you work, but will still save battery on nights where you go out rather than going to a place with a charger nearby.
For charger, I set mine to AC because of how much faster it charges and getting emails during the night don't wake me up. (I sleep w/ it plugged in like many people) If things like email / other push notifications bother you at night, leave this off.
Screen. Leave this enabled. Simple as that.
Make sure Traffic is enabled. This allows apps to finish data transfers / downloads before data is cut off. I set mine to low at 15s so it doesn't interrupt downloads.
Apps. This is very important for a lot of people. Everyone has at least one app that they need to have data access going to when the screen is off. For me, it's Pandora, Google Music, and Google Maps. I set those 3 apps to enable / screen off. Meaning that if it's running on the phone, and it's in your pocket, those apps get as much data as they want because JD will be disabled for as long as they're on. Just hit the configure option, and choose which apps you want for enable / screen off.
Last one. Location. Just hit enable. When you connect to Wifi, it will remember your location w/ cell towers and not GPS. If JD detects that you are close to that access point, it will turn on WiFi again for you. It takes a bit of time to "train" Juice Defender to get the right position. But eventually, it works great!
Anything I didn't cover are things I didn't touch. (brightness / bluetooth / CPU controls)
Keep in mind, Juice Defender NEVER blocks your ability to receive / send texts and calls.

Thanks bro
check your Google Plus

Thanks for that , am trying those settings now.

I have always hated that program and found it to screw up phones. Most of the time it actually makes batteries worse. Just my two cents.

I'm not sure what to think of it. I set the settings as per Mushrooms suggestions. In an hour and a half, I've eaten through 14% of my battery with my screen off almost the entire time.
It says it's giving me 1.78x the amount of battery I normally would but normally I wouldn't be down 14% in an hour and a half.

yes, this has always been the general thought and what is posted most often.....I used to think the same thing until I used it on my SkyRocket.....it made a huge difference. I would get home from work before having JD on my phone and be at 20%.....when I installed JD after about a week....I would get home from work and be at 50%
So it may not work for everyone but my .02 cents is, try it and don't just automatically assume because people post that it sucks, that it sucks. Cause for me it is a lifesaver.
This coming from a guy who used to post the same things cmucooper just posted....I hated JD and bad mouthed it every time I could. But I never really used JD, I was always just spouting off what someone else had said about it....now I regret that cause it's worth it.

I set mine up per Shrooms suggestions and I am in 3 hours unplugged and at 93%.....normally it would already be at 85% so I am in the positive.
Dunno why urs is in the negative

I'll give this a shot. My battery has been stellar when screen off. This would be cooler if it makes it even better

Yea I would try the default settings first for a day or two, then you can try the settings posted here to see if it gets better or not. I also didnt like this app with other phones as I didnt see a difference but on the note's battery,I've been unplugged from the wall charger for about an hour on wifi with the screen off and its gone down 1% with me checking emails 2 times. Maybe not too impressive to some but for me this is good, I'll have to see when I'm at work this week.

unplugged now for a little over 7 hours and at 70%

Sudden Battery Drainage

I understand all these battery drain issues that the prime has been having but haven't actually had them, until now. I used to lose about 2-3% overnight but suddenly I am losing around 15% because it won't sleep. I go into the battery setting and it shows it been awake the whole time. Now I am sure if I looked around I may find a fix but it just seems a bit odd that it has just suddenly occurred. And its not a wifi drainage issue as I usually put it to sleep at power saving mode and wifi off. Just asking why?
Thanks,

I think it could be the Asus weather widget which I had set at 1 hour refresh rate.

if this just recently occured out the blue, likely a rougue app or something you recently installed. an app running in background or sync is likely the culprit.

Just put Skype on it but that's not signed in most of the time

every android tablet and phone i have does this occasionally, and those occasions are when i either play video or music. some of these media players employ a wakelock that will not disable after you put your device to sleep. sometimes a reboot will work, sometimes not. most of the times the reboot keeps it from draining. even force quitting all my media apps wouldn't work.
so basically i reboot every time i use any type media player so i don't get the drain - netflix doesn't require it, dice and just about every music player does. i'm not sure it this may be your problem, but it may be a possible solution.

I find that making sure to check the last two settings under Asus Customized Settings helps this. I was waking up in the morning to find my dock dead everyday before I checked those two settings. The only down side is when I turn the screen on and wake it up, it takes about 5-10 seconds to connect to the wifi. No biggie.

Use better battery stats and see what is causing it. I have read that skype does drain battery pretty bad. And even if you're not connected it still runs in the background at start up. Another app I would recommend is Autostarts. It allows you to disable apps at start up. I know system tuner is free and has the same functionality but I find Autostarts better. With ST, you just disable the app at start up, with Autostarts you can disable it at start up, shutdown(which some apps fire when the tab is being shut down and other system events), also other events. Like some apps fire up when you get a text, or when your connection changes etc.. I just think Autostarts has more options.
Also dev Entropy has a thread in the GS2 forums about know battery drainers. Some of it applies specifically to the GS2 but there are a bunch of general battery killers listed
http://forum.xda-developers.com/showthread.php?t=1308030

If you go to setting and battery it should show you which is using the most battery. The first one on top. If its android system, you can click on it and it will show you a list of whats been using your battery which may point you to the culprit. In my case, media was the only thing in the list. And I know if an SDcard is inside my dock it will drain battery. So after removing it the drainage went away. Havent had the drain issue since. Again yours might be different so check the battery usage.

Thanks for the feedback guys, the first thing i am gonna do is charge it up after it fell flat right up to 100% then try some suggestions. I am thinking a reboot could help it.

Push Notifications Don't Work With Screen Off (Gmail, Talk, Voice, etc.)

Recently I disabled the best wi-fi performance option (I enabled it on accident while messing around with settings on launch day) which obviously increased my battery life dramatically by actually allowing my phone to go into deep sleep. But now I hit a new issue.
Before I go on, I want to state that I DID apply the SmartSync fix and that my data IS working while my phone is in deep sleep.
New emails I receive with Gmail app do not get pushed to my phone as they should. They are anywhere from 5-15 minutes late if they even show up at all. If I happen to turn my screen on, automatically I get the notification of new emails.
Is anyone else having this issue with Gmail or any other app? I find it strange that while I have data (wi-fi/3g) enabled and working with the screen off, emails still come in delayed.
Any help would be appreciated. I have searched around and most of the answers I came up with (regarding HTC devices like the One X) had to do with SmartSync messing up the connection or someone not having the notifications enabled. I'm at a loss 0.0
EDIT: I tested this with Google Talk had my main account up in Gmail and in another browser windows my other Gmail account. Added both of them, talked to my self, if my device screen was off, I would either get it 1-2 minutes late or not at all. Once I turned my screen back on, the notifications poured in. I also tried the same scenario with my main Gmail account logged off (in case it was canceling out the messages to my phone, which it wasn't) and I had the same outcome. I edited the title to reflect that this isn't a Gmail only issue.
EDIT 2: Did more tests, I tried turning Wi-Fi off completely and running the same tests as above to my surprise everything worked as expected. I initially thought it might be because of my 5Ghz Wi-Fi band, so I tried it all again on my 2.4Ghz channel -- had the same problems as before. Somehow the issue pertains to your screen being off and Wi-Fi being on.
EDIT 3: I just tried streaming Pandora and shutting the screen off (maybe WiFi WAS somehow shutting off) Pandora kept playing no problem. I messaged myself on Talk, got the notification right away. This is very bizarre 0.0 But it might confirm this only happens when the phone is in deep sleep mode... Still doesn't answer why it doesn't happen on 3G or why notifications sometimes still come through.
EDIT 4: Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:
If I have some thing like Pandora running then it will continue to run once I shut my screen off. But if WiFi isn't being used and I turn my screen off and then lets say I try to connect to it with Cerberus or ping it from my PC or something it will not even though the router reports it as connected.
Very strange behavior.

This is interesting...maybe the wifi performance toggle is associated to the smartsync, and all?.....I will say that with it unchecked I am getting some really really good battery life here compared to previous phones....but I also notice at times when emails are not pushed till I wake the screen during the day....Also the fact my wifi doesn't automatically reconnect to my house when I get back from work till I wake the screen...little things like that...
Havent messed with the best performance setting but will try it today now...

Try installing this https://play.google.com/store/apps/details?id=com.logicvoid.powersaversettings&hl=en and unchecking "put data connection to sleep." It may not solve the issue but its worth a shot.

Okay, I just tried streaming Pandora and shutting the screen off (maybe WiFi WAS somehow shutting off) Pandora kept playing no problem. I messaged myself on Talk, got the notification right away.

Have it, and it is unchecked. That's the weird thing, wi fi doesn't actually turn all the way off because SOMETIMES I do get the push notifications (late, however).

what is the smart sync fix?

When I installed this app, my cpu reduction and frame rate reduction was enabled. Does that mean this is standard with this phone. Does using this app to disable those setting improve the performance?

Issue continued overnight, tried various other things and nothing seems to fix it. I want to get my notifications but I don't want to destroy my battery life xD is anyone else having this issue?

It's definitely not a hardware problem because if that was the case the phone wouldn't work with wi fi almost at all. My wi-fi connection is rock solid even when the screen is off, just for some reason it won't notify I have the messages until the screen gets turned on.
I did some tests on my gf's stock phone and she's having the same issues, I told her to do some tests on her parents wi-fi when she goes there. I wonder if sgt slaughter has any news.
Btw if you definitely need them on time and need to be on wi fi but don't care about battery life that much just enable best wi fi performance.

Actually more like a Smart Sync break ... The built in settings/app put your data connections to sleep when your phone goes to deep sleep; this is done to save battery when phone not in use for extended period.
Some folks hate losing the data connections so a flashable "fix" is available for the "problem" ... Look around; you'll find it
Sent from my EVO using XDA

its a sense problem, there's a thread in the one x forums on how to fix it. I'll post when I get home if I can find it. it shuts down to a 'power save' mode after a while plus after midnight or 11 or something.

Just wanted to update that I installed a custom rom that contains the WiFi fix mentioned and although my WiFi doesn't seem to drop how it did before (at least after one day) my notifications are anywhere between 4-10 minutes late on average through WiFi. This seems to be across the board for Exchange email, Gmail & Google Voice.

Yes my setup also had the wi-fi fix, I can even see my phone connected to the router when the screen is off, the connection is strong.
I had a suspicion it was probably the basic transfer rate of the browser and for some reason I could not adjust this on my fancy 100 dollar router with dd-wrt flashed onto it so I set up a repeater with my older router on stock settings. It seems like the notifications are coming through better now (albeit not instantly) but at least I don't have to turn my screen on every time. It might be a placebo effect or just luck (because at times it does work even with my other router).
EDIT: Ignore the italicized sentence. It was just a stroke of luck, the problem came back.
I'm out of ideas at this point xD

I am having a similar issue as well.
I am rooted and running Fresh Evo LTE 5.1.1 which has the "Disabled SmartSync deep sleep mode" already installed. I also leave my WiFi off (for the same reason as the OP outlines - messages are just plain not arriving or if they do it's after I turn the screen on).
I use gtalk as my primary form of communication on my phone and what seems to be happening is messages from my two closest friends are never arriving. It's hit or miss but seems to be ~45mins after my screen turns off that they send a message and I never get it. One is on Sprint on my family plan and the other is on Verizon. The weird thing is that if I look in my gmail > conversations the messages aren't there either.
I haven't been able to verify any SMS messages that I haven't received but I have noticed that my email notifications seemed a bit wonky but this issue may be fixed with changing my "push" hours (which is retarded to have factory set to only push email between 8am - 8pm).
Question for the smart kids in the class: When does the phone reach "deep sleep"? Is it around ~45mins after the screen turns off?

I also have the dual core mod which I BELIEVE sets my deep sleep right away which is probably why I have the problem more often than you do. One question just so we can start gathering facts large scale, if you're on 3G do you have the problem still? What if you turn 'best wi-fi performance'?

Correct - I have this problem on 3G. I run on only 3G because the problem is more prevalent on WiFi, but still very common on only 3G.
Currently I have "best wifi performance" turned off. Do you want me to test with it on or off?

On. When I turn it on it pretty much eliminates the issue, it acts just like 3G. But for me 3G is almost perfect (a couple seconds of delay but I can deal with that). Remember though that if you leave it ticked on it will destroy your battery life.

WiFi is on, best WiFi performance is on as well.. I'll run it this way a couple of days and see if I can replicate the problem.

I just wanted to say that I've been having similar issues. I have tried turning on best wifi performance, but I don't think that is helping. For one thing, when I have that turned on, when I wake the phone, the wifi is often times not connected, and it shows 3G. Then it will connect to wifi shortly after I wake the phone. On top of that, I'm still not getting notifications on time. I was notified of an email when I woke the phone that actually came in 10 minutes earlier. Hopefully HTC/Sprint is aware and working on a fix.

Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:
If I have some thing like Pandora running then it will continue to run once I shut my screen off. But if WiFi isn't being used and I turn my screen off and then lets say I try to connect to it with Cerberus or ping it from my PC or something it will not even though the router reports it as connected.

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!

You screen is using most of your battery. Check the brightness levels. Are they on max or close to it? Switch it to auto

Oh thats easy.
You're phone is always "Awake". It doesn't go into Deep sleep like everyone elses. If you take a look at the first picture you linked with the graph, it shows that the phone is always AWAKE.
For comparison, I have attached mine as a reference but something is DEFINITELY keeping your phone awake.

Can't really see anything that stands out per say...
If you see anything on that thread or any apps on your phone that you think could be keeping it awake, just uninstall them. I would suggest trying to remove them a few at a time just to narrow down which ones are keeping the phone awake.
Also, apparently this app helps a lot (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and Better Battery stats should give you a better idea of which apps use the CPU while your phone is trying to sleep.
Oh and remove any task managers you have installed.. Those tend to be the worst offenders.
One last thing, found this on another forum:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"

Are you on the 3G network a lot or weak signal areas? Is your phone hot around the bottom? If yes to both, most likely it's because of the system attempting to find a better signal. When I was swapping out my SIMs, in various countries, I only have 3G network and my battery fully drains in 7hrs at idle. The only way i can go a whole day is to place my phone into airplane mode or wifi only to conserve the battery.

my battery runs at-most 13 hrs........................

Welcome to smartphones. The calls alone will drain the battery. Seven hours isn't horrible for all that. It isn't a flip phone.

maybe you have to flash a new rom

If you want, you could try to flash a custom ROM. I had the same problem that you have, and I flashed Revolutionary S5, and now my phone lasts minimum two days with the same usage, maybe a bit more.

Titanium Backup will assist a little bit. When you do a backup of an apk it will tell you if the application is running. You can find all kinds of sneaky apps this way. Many of them were ones I didn't use and didn't really want. That will probably yield minimal results, though. Keeping a black background helps on my S3. Colors, widgets, and live backgrounds will drain the battery. Turn off the menu and back key lights. You know the buttons are there. Turn off all haptic feedback and key press sounds. Of course, try to lower the screen brightness. Leaving my data and sync on hasn't caused me any problems, but you will save some battery by turning them off when not in use. I also read a post about hidden menu options that ran even when they weren't meant to. That was an issue that destroyed battery life. Some ROMs also have settings for data connection type. You'll save power by telling your phone to not worry about gaining signals like 4g, 3g, etc. As other people have said, try out some ROMs that make battery life a big priority.

it CAN get better
if you want to have a good battery life, use custom rom and kernel (or a modified stock like omega rom), watch out for wakelocks + apply these settings:
