What sucks YOUR battery?

I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).

Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.

The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.

Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.

Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.

my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.

My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
Sent from my SPH-D700

So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.

First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

+1 to this, after I changed this setting my time without signal is about 3% before it was up in the 50's. Good tip right there

Does anybody have data from other android phones - nexus, droids...?

3-4 hours of talk time takes up 70% of my use during a 10-16 hour usage. Second would be my screen.

My screen is 79% and cell standby only 7%
My screen is all the way down, even tho with the new update I notice my screen got dimmer than before.

[Q] Battery life makes me cry

(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.

A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.
http://www.bakedsnackshack.com/source/
Download Bakedsnack1.6 and Step 2.
Make a backup.
Wipe data/cache
Install 1.6
Boot the phone up
Reboot into clockwork
Install Step 2
Boot the phone up.

I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.

Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.

From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thank you for your reply, but as I said in my first post, I was using both JuiceDefender and Superpower to make sure data was off in the background, and as I said in my most recent post, I did disable the OmaDrm service as well as enable/disable Airplane Mode to lower my TWS.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.

I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

Used BS 1.6 w/ step2 kernel today. MUCH better battery life but my phone was acting just a bit wacky (locked up and required batt. pull twice or three times)
Not the biggest fan of the aesthetics of the ROM.. but I'll live.

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?

I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.

Question about sleep in Iconia Tab

Hello all,
Trying to find some info about some behaviour my Iconia has.
I love my device. Way more capable than my wife's Ipad and all that. There's only one thing that irks me: battery drain while the device is idle.
I also have a B&N Nook 1st gen (for books) and an EVO 4G. I leave and use the Iconia mostly at home, close to the WiFi. I'll take it out for long trips and such, but it stays close. I have it set up so that the WiFi antenna turns off when the screen does. Low brightness on the screen, will only charge the battery when it's low enough to charge, etc. It stills drains close to 6-8% if I leave it alone a couple of hours.
Earlier today I rooted the device and use Bloatware Freeze to freeze some stuff. Eventually I'll get rid of some of the gunk the tablet has installed. I want to figure out how to shorten that gap. It doesn't make a whole lot of sense to me that the tablet left alone consumes 8% of battery charge! I mean, if nothing can be done then so be it, I'll learn to live with it.
For my money I would bet that there is something hidden in the Iconia's OS build that thinks it is a 3G/4G device. Now, I'm wondering what would happen if I were to take the next (logical) step and put another ROM in it. Would this make a difference? If I can make the battery drain stop at 5% or less, that would make this perfect.
Thx!

I leave my device with airplane mode checked, and then re-check wifi (as airplane mode will initially turn off your wifi). I get no strange programs showing up in battery usage now.

Will certainly try...
I'll try this next time I head out. Will leave her in Airplane Mode and will check the battery level when I come back.
I did disable the GPS and all location settings. I do not need it to know where I am, since I have the EVO for that.

Right on, let us know if that helps ya out

Well I'm glad I came across this. I didn't even think about leaving the GPS on and consuming battery. Also, where did you adjust for your wifi to turn off when the screen goes off?
EDIT: Nevermind, I found it.

I am developing an app that uses bluetooth and I noticed that if I leave bt on my tab will go dead in 2 days, if I turn it off it can stay idle for several days before needing a charge. I leave the wifi on all the time.

Wow I don't even have 8% drain with Wifi on all the time. There maybe something else in the mix. Most of my drain is the screen as I set it to auto and in my home it ramps up brightness most of the time. Is it possible you have a rogue app? Have you tested the tablet 'fresh', ie: after a factory reset with 1 google profile set up?

This is interesting, on 3.01 & 3.1 I've had zero drain with screen off w/up to 16 hrs. Settings : Wi-Fi disconnect policy never when plugged in, location & security use wireless networks on & gps on. Airplane mode , always off. I can't understand why you folks are having these problems. Hope we find out. Oh & by the way that's not charging.
Forgot to mention I use Juice Defender.

Update
Well, after much tweaking I think I'm somewhere where I feel comfortable. As a disclaimer I don't take the Iconia with me on my daily commute. Again I take my EVO and my Nook with me. The tablet spends the entire time I'm out in the office at home, unused.
I disabled all screen animations and I'm using the tablet on the lowest brightness setting.
I disabled the GPS and all location-related settings.
I rooted the tablet and am using Bloat Freeze to freeze/disable some of the Acer 'junk'.
I put the table in Airplane mode before heading out.
Last night when I went to bed I didn't use it (I was reading a very good book and I did not use the tablet to watch any of my shows). So I put it in airplane mode after I played with the new Google Music app (Impressive!). I went to bed around 11:00 and woke up at 5:00. In this span of time, battery went down by 1%.
Used it this morning to tweet, check a couple of websites, email. Was @ 71% at 7:00AM. Came back close to 7:00PM. Battery was at 67%. Right now (8:50 EDT) it's at 1d 19h 55m on battery @ 59% charge. Heavy usage of TweetCaster, TuneIn Radio, Browser, Market, &c.
Mind you, it was not used for close to 8-9 hours or more. If I were to take it with me the consumption would be more, but then I would probably use Airplane mode when it was not in use. Besides, I can't use it at work b/c the wireless is not compatible.
I'll keep doing some research, but I'm comfortable. I accept the fact that it will drain regardless, since the OS is up. The previous consumption was too much, and I think I can live within the 2% - 4% consumption rate. If it can go down to 1%, though, that would be even better.
Any other ideas welcome.

beautiful Widgets comes with a widget to disable/enable wifi like we're all used to on our phones.
I loaded prime 9.3 today because I wanted to try a 3.2 rom (for GPS and sd-card reasons). On that rom I noticed the 3g settings were visible until I added the line "ro.carrier=wifi-only" to build prop. I was able to see cell standby show up in batt usage.
Not sure if you guys knew it or not but under battery usage you can click on the graph to see a graphical depiction of what hardware used the battery when. If GPS was active when it shouldn't have been you'll see it there.

Interesting...
Are you suggesting that the 3g apk is active on the 3.1 image? I posted this question to a developer in Market that has an app that kills this on the Iconia. Maybe that's the other 2% - 4% I can kill.

Prime is a 3.2 rom. You could try adding that line and rebooting though.

To the stock 3.1 image? Interesting. Any instructions?

You'll need an app like root explorer that will let you mount the /system partition as read/writeable. In the /system directory there will be a build.prop file that you can open with a text editor (root explorer has this feature built in). You'll see many "ro.xxx" lines. At the end of the first group you'll just need to add the line "ro.carrier=wifi-only" without the quotes. Save and exit the file. Reboot tablet. On reboot, it will read the values in build.prop.
On the prime 3.2 rom, the settings for mobile networks are visible without that line added to build prop. I was actually seeing cell standby in the battery usage list. I never saw that on the stock rom. I use a toggle button for the wifi to quickly turn it on/off from the home screen and that keeps wifi from using any battery while sleeping..
I really doubt that GPS is the culprit in your case. Did you click on the battery usage graph to see what hardware was using the battery during the period of sleep?

Also remember
The % charge that the system reports is not always a very accurate indication of how much charge your system actually has - what matters is up time and how long you can go between charges.
Airplane mode is your friend - no real need to disable animation (has nothing to do with idle charge) - the only thing I do is enable airplane mode when away from charger and not using my tab - some of the drain you are reporting could be due to your system scanning for open hotspots.
Also remember all it takes is one poorly coded app to totally screw your battery over - as you are rooted, quite easy to check for apps that relaunch themselves even after closed, apps that want to phone home every 60 seconds - etc.
Would highly recommend you take a close look at any non-stock apps that you have installed.

[Q] Slow charging with orb?

I got the orb recently and my plan was to use my phone as a bedside alarm clock with it. However, when I have the phone on "desk clock" mode while on the charger, the battery slowly drains overnight by around 1-2% every half hour instead of going up. When the screen is off, it seems to charge fine. Is the orb just really that slow at charging? It kind of defeats the purpose if it can't keep a steady charge with the screen on as I like be able to just glance at the time while in bed instead of having to turn on the screen first.

well the orb wont charge as fast as wall charger
but if it doesnt provide enough mA to charge while screen on i guess there is something wrong. however i dont have the orb, so cant help you any further.

It should still charge with the screen on. Mine will gain 1-2% every 10mins with the deskclock night clock on. Are you using a case?

No case at all. I am using the power adapter that came with it too, because i read using a different one caused problems too. I am however using visceralpsyche's gamma color settings from franco's thread which require you to have your brightness at 50%, but I should still be able to get a positive charge I would think.

i think you definitely still should. I know that if you place the phone on it centered near the bottom half (if you do it vertically, the phone will be about 1/2 - 3/4" from the table or whatever surface the orb is on), thats the optimal part of the phone to have touching it. If it's still not working, I'm guessing something isn't quite right with it.

I've tried a few positions all with the same results. I did notice though that with the first 20 minutes of charging, it will go up like 3-4% like it should, but afterwards it just goes on a slow and steady decline. I guess I'll contact Google about it, and I already had to sell my DT-910 because of the problems with that charger :/

Screen stays on after battery gets fully charged

Got a weird problem with my AT&T stock non-rooted S4. About 4 or 5 times since I got it on release day when I charge my phone and I get the notification that it's fully charged the screen won't turn back off. I use a Belkin Conserve socket that is set to shut off after 3 hours and I've woken up after charging to find the phone dead. I've managed to catch this happen once and when the fully charged notification comes on the screen won't go to sleep, it just stays on and flickers a little bit. For all but one of these instances I had blocking mode on so I'm not disturbed by email or text notifications in the middle of the night. It did happen one time when I didn't have blocking mode on. I use a pin lock for my lockscreen and usually have BeyondPod playing overnight (only one hour long podcast while it's still charging) if that makes a difference. Is the function that enables the screen to stay on when you're looking at it malfunctioning? Any help? I've attached two screenshots of battery life when this happens.

So in settings under the Developer Options, there is a setting "Stay awake" if checked screen will never sleep while charging. Now I see that your Belkin shuts off the power but your phones still detects the usb plugged into a power source.
I think things happen in this order: you hookup your phone to charge and shut off your screen, phone charges to 100% and screen lights up saying fully charged, it stays on because of that setting, Belkin kills the power, it is still hooked up to USB so ... you get the rest.
I would find that setting and disable it.
if your next question is "I don't see developers option" it is hidden by default in android 4.2.2 so to make it available, go to Settings > About phone and tap tap tap Build number seven times. Return to the previous screen to find Developer options. Or Indiana Jones might pop up and give you the cup to get eternal life !!!

Thanks for the reply Commodore64 but I already checked that setting when it happened the first time and it's not checked.

No one else has had this problem?

I have this problem as well as my wife's S4. around 3am, I notice our room is bright with our two phones' screens on. It will stay on until the morning.
In the developer's section of the settings, the stay on when plugged in is NOT checked.
Also, on our phones, we notice the phones overheating because the screen is on for hours at a time at night.
I've just spent an hour looking through the internet, and while many report this, they are simply being dismissed by others as in having "checked" the setting in developer section.
Also, when the batttery does get fully charged, the "Battery if full, unplug the power" notification also rings the default notification ringtone. I've installed phoneweaver to set my phone to no sound overnight, but it only stops the sound, the screen still stays on and phone gets really hot.
This is turning out to be a huge problem for us.

Do you use a PIN (number) lock? I did but switched to the pattern unlock and it hasn't happened since. Also, I've been trying to charge only during the day or evening, not overnight. Maybe, since I charge during the day and I use it periodically while it charges it doesn't go into a "deep sleep" like it would if it charges while sleeping and the full charge notification would keep it awake. I don't know exactly why but it hasn't happened since. Hope this helps.
