Rooted unrevoked and battery is worst - EVO 4G Q&A, Help & Troubleshooting

Are you running stock Rom? I suggest using an SBC kernel..

more info needed what programs have you added. something maybe causing a wake lock issue.

rooted my new EVO with unrevoked3,then installed netarchy-toastmod 4.3.1 kernel and my battery lasts all day with moderate usage

I doubt rooting it made your battery worse. there are many rom choices and apps to help you out. With rooting comes tinkering and it looks like its time to tinker. Look into an app called Spare Parts and another one call Autostarts

^^ is your best bet to find out what's eating your battery.
Cheers!

The other issue is your battery stats may be off if you did something odd during rooting. There are several ways to fix that, the generally accepted way is to charge the phone while its on, turn it off completly, then:
1: Unplug phone when light is green
2: Plug in the phone
3: Repeat 10-15 times

I had the same issue, and this is what I did to fix my battery.
1. let the phone die completely, IE when the phone cannot turn on at all anymore.
2.Leave the phone off, let it charge overnight.
3.Verify that the phone is at 100% by going into settings->about phone->status
4.Power the phone off.
5.Boot into recovery
6.Wipe battery stats.
This should fix the issue, if not then consider using a different rom/kernel combo. I myself am personally using CM7 and suffer maybe 40% drain at most with my phone in my pocket with a typical 12 hour shift at work.
**Also, turn 3G off if you aren't using the internet, facebook, or Gmail ect ect. You can still recieve phone calls and text messages using this method. I believe there used to be an option to only have 3G running when the screen is on but i'm not 100% sure if this is still available.**

Yeah like I did that crazy charge thing I read about where you let It die and it helped for a bit and now thing just goes down like 20% after 30mins of just sitting in my pocket

Battery Drain overnight

I don't know what is wrong with me (I know this is something I'm doing wrong), this happens EVERY time I have an android phone.
I think I'm not closing an app or something and the battery drained overnight, it happened when I had a G1 and an X10... Anyone experienced that?
Is there a way to close apps properly on Android? I don't want to have to install something to manage whether my apps are open or close, I just want them to close when I'm done with them....

Internet.. guessing you dont use it at night so try this.. 2 methods of doing the same thing 1) +/Widgets/Settings/Mobile Network and just toggle that whenever you don't need to use 3g connection, or before you go to bed. 2) Hold Power Button/ Mobile Network and make sure it says Connet to Internet is OFF..
for me, this gives 3 days of battery (also doing some under clocking at night ) loving the phone!
Ive experienced high battery usage on a HTC Desire, a Google nexus one and now on a Samsung Captivate. It always seems to be Android OS and the usage is even higher than display which is ridiculous.
It happens on and off and its really quite annoying. I always think Ive found out what causes it...and then it happens again!
I have to ask the question, but have you regularly been using the same 3rd party applications with each of the phones?

Dave

I realize the logic behind the question you're asking. Ive noticed android os battery drain without any apps installed (i.e. stock only). It doesnt seem to happen on a regular basis though.
At one time, I was pretty confident it was a generic charger, another time after usb connections and even something associated with google push services.
Not really sure what it could be. Its like those experiments at university where there are way too many variables, so the only option is to sit down and data log until a trend emerges. Frankly, its a phone and its too much time to actually sit down and do that. (Yes I know im lazy )
2-4% battery drain is normal at night, if you have airplane mode on or at least 3G / WiFi data connection off. The drain should be between 2 and 5 mA for most of the time.
There are a few battery related threads, try comparing those results with yours, we did some extensive testing too in one of them.
To pinpoint your problem try one or a combination of these three tools: SystemPanel, Power Tutor, Current Widget (maybe one each night). Let them monitor your system overnight and see what's the result.
I have recently done testing for 4 nights, two with SetCpu underclocking profile at screen off, and two without it. There was no appreciable difference between the four runs.
i use an App to turn on airplane mode over night, i stared with an app called "sweet dream" [Link = http://www.androidzoom.com/android_applications/tools/sweet-dream_jtvk.html?nav=googleDownload ]
and now use timeriffic [link = http://www.androidzoom.com/android_applications/tools/timeriffic_tdl.html ]
it really does help the battery life.
Or just plug it in overnight? This seems to work fine for me!!

Have you tried conditioning the battery?
Calibrate your battery then reset your battery stats. It could help. If you flashed a rom while charging or during the first boot screen on first boot or on USB, battery calibration will need to be performed. It made a massive difference for me after multiple flashes.

I decided to install Advanced Task Killer, all is good now, must have been some app draining it.

[Q] Questions about CyanogenMod, and general battery life

Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?
Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

Another thing; I've got a friend on Stock 2.2 Sense (battery sucking widgets filling the home screen, etc) with 100% brightness and mobile data constantly on and he gets better battery life than me (20+ hours!) What is going on!?!?!

stock 2.1 idle drain

So...I'm using 2.1 and for some reason when I'm not even using the phoone..the battery drain is ridiculous. Since I'm new to 2.1, does anyone know what is causing this? Any processes I need to end? Any thing I need to remove?
I'm straight up rooted stock 2.1. No custom roms, just a custom kernel. I only downloaded Pandora, Wordfeud and SetCPU.
Edit: I also wanna add that I leave on 4G as well and I see it idle out and when I turn it off and leave it off I still experience the same amount of drain so I dont think its 4G.
And for more details on the drain...I went to sleep for about 3 hours and during that time I went from 91 to 42.
Edit2: Im gonna actually see if maybe it was just the kernel...I was using the first version of a kernel, not its latest version so Im going to put on the latest. But still, Id liike to know if it was a common problem and how most people fixed it.
Kill the omadrm process with each phone reboot. (Forgot exact name, but that is close) If you aren't always in a 4g area, having that radio always on will drain the battery.
Sent from my SPH-D700 using XDA App
Edit: Also double check your phone standby time and see what percentage your Time Without Signal (TWS) is at. Toggle Airplane mode after each reboot will correct that bug.
Also fyi you can use Tasker to toggle airplane mode for you automatically every boot

It you can just.install spare parts and.look. also check your time without signal. If you don't reset your radio its prolly 50%. Whether.that is.cosmetic or actually does cause a battery drain its still good to do.

Battery life even with removing a few apps is pretty bad.
I think the most I got after a week of tests was about 18 hours and that was with almost no use.
Try downloading JuiceDefender from the market. It's free. What it does really is enable/disable your 3G/4G/WiFi connection when your phone is not in use. It also enables it every 15 minutes (default setting) to get email other updates such as weather. I am not kidding when I say went from an 18 hours to 72 hours hours. Granted, that was with little use.
Can download JuicePlotter as well to get an idea of how your battery is dropping and holding.
Side note that WordFeud constantly runs in the background, so that WILL rape your battery. JuiceDefender will keep it in check. Best app I ever got.
For reference, under 2.1 with JuiceDefender I would lose only about 1%/hour at night when I was sleeping.
Under 2.2 it's more like 2% per hour >.> and I've yet to figure out what's draining it.
I thought I'd chime in since the OP mentioned Pandora. After installing Pandora I noticed my battery drain had gotten significantly worse even when properly quitting out of the app. After uninstalling Pandora battery drain has normalized to the way it was before.
Also, setting your network to sprint only helps with battery too.

maybe where you live it does, but thats an awful idea if you are in a town with little service because it will spend more time searching for service because it can't roam (i live in the middle of nowhere in new hampshire).
instead try to update your PRL. download the SDX stock app removal apk. remove the drm crap. and reboot. then charge your phone all the way, reboot into cwm, and reset your battery stats. then let the battery drain all the way and recharge. that should improve it significantly. thats what i did and it worked pretty damn well. battery life is upwards of 36 hours nominal charge now. and my phone used to drain battery WHILE i was charging it if i used it at all. and that was with a 1 Amp charger. also dont let your battery overcharge, mine seems to drain easier when i leave it plugged in all night.

Is something wrong with my Xperia Play R800x?

Ok well let me just start off by saying. I LOVE this forum and the helpful and friendly people. Lemme give ya a run down on what I'm rockin' on this marvelous piece of technology.
Bootloader Unlocked - Check
Root - Check
R800x Timescape UK Firmware ROM - Check
V6 Supercharger - Check (Could use help making it start on boot.)
Better Battery Stats - Check (Could also use some more help since I'm a noob XD. More below!)
Battery Life - QUESTIONABLE
And here lies my problem here. Ever since I switched to the UK Firmware from Verizon's I've noticed the phones true potential and love the UK Firmware. However what is up with the terrible battery life? I've tried everything... It seems to DRAIN 1% every 5 minutes when I'm at school!!
BetterBatteryStats talks about wakelocks. I get this one sometimes called UID and have no idea what it is, and have looked for a solution but found never in ACTUAL terms I could understand. Also there's a blue bar and a red bar on the stats for those. Can someone please tell me the difference between them?
I've deleted Juice Defender as some people said it actually DRAINS your battery more. I've also heard this phone lasts sometimes 3-4 days on a FULL CHARGE?! I'd like that please! :O
Well when I'm at school I put my phones Brightness to 30%, Vibrate, and off WiFi.
I listen to Music and that seems to drain the battery ALOT more than I think it should.
Also, when playing Asphalt 6 HD, I was at 57% battery, I played for maybe under 10 minutes and had 44% LEFT!!! That's TERRIBLE!
Can someone please tell me how to make my battery last like others have it?
I also have 2X Battery installed but disabled and only showing my battery % on my taskbar up top.
Thanks again in advance for your answers and I hope I have provided enough info. THANKS!
If u don't use it during school then power it off. Also kill some tasks so your phone won't work hard and kill morw battery life.

I do use it during school. Sometimes as a Calculator, to text my family or if they have to call me in case of emergencies. I also game on it at lunch or listen to music when on a free period so...
And I do kill tasks all the time. It seems to just open themselves back up. Also I played Dead Space last night with 100% charge for maybe about an hour or 2 and the damn battery drained down to 55%!!!
I was on WiFi as well...

You honestly can't expect a game such as that to run on this phone and merely sip at the battery's juice. The percentage remaining when coming out of an intensive task, such as watching video or playing a game, isn't entirely accurate. Check the battery again after a few minutes of idle time, and it should be a little higher than it was before.
I use an app called Battery Defender. It's very easy to set up, and the main option is to kill the 3G data while the screen is off. You're still able to receive calls and texts and such, but the data is off, since you're not using it. That saves a lot of battery for me. You can also set it on a timed profile, where it shuts off all network connectivity during a set time.

Thanks I'll give that app a try.
Also I just feel I'm being mis-leaded by others then. Because I read on the android Forums people play games from 1-2 hours, stop, go to the store or mall for like 5 hours, come home, play again for another hour, and sleep and wake up with it at 7% charge or something.
Are you saying ti's normal for my battery to suck that much juice on Dead Space?
Dead Space is one of the most graphics intensive games you'll get to see in this phone. It's not Cut the Rope...
Well.. despite my other questions is anyone able to answer them..? ABout the battery stats app and such?
Also what would seem to be a normal rate of 1% battery loss? How many mins or hours do you think seems normal?

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it
I would suggest you to do a fresh install. Wipe everything and start afresh. Don't restore anything and see what happens.

Make a backup of all your data, then do a fresh install. The battery calibration app is simple, charge your phone to 100% and click calibrate. Then let it die to 0% and fully charge without any disruption..it's pretty simple

Must I make a fresh install or can I do it without a fresh install?
The battery calibration has nothing to do with a full wipe and reinstall. The fresh install is simply to fix problems that you are having, that no one else has, or doesn't have in such great force.
If you're worried about losing your data, get an app called Titanium Backup. It will allow you to backup your apps and app data to your sd card, then restore them at any time you deem necessary. There is a free version, but I would definitely recommend buying the unlock key. It makes your restores faster, and enables some specific functions that are locked out of the free version. This is my third Android phone, and the app has proven its usefulness time and time again, across each of them. It's the best way to port installed apps from phone to phone, as well.

battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?
It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

well after the screen 40% we have android OS @ lower 30%
Do you have an SD-Card in?
I was getting the same battery life, took out my SD-Card, and I'm getting 7 hours on screen time with stock battery.

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.
GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.
It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....
