High battery drain

Im trying to find out what is draining the battery on my EVO EVEN WHEN THE PHONE IS WITH THE SCREEN OFF and SUPPOSED to be in STAND BY MODE (using the power button on the phone). I have SETCPU installed to LOWER the CPU to 245/384 when the screen is off.. HOWEVER THE BATTERY SEEMS TO DRAIN .
This afternoon I charged he batter till the green light came on. Made one phone call for 10 minutes and then later another one for 10 minutes.. I do have GPS and BLUETOOTH ALWAYS turned on since I use them all the time WHEN the phone is on for various APPS and my bluetooth earpiece and car adaptor... After those 2 calls the phone is down to almost 70% from 100%...
I have SYSTEM PANEL and also JUICEPOLTTER, SPARE PARTS and MINIFREEMANAGER installed and the programs are set according to what I have been reading on here...
SPARE PARTS tells me the phone has be MORE THAN ONE DAY with sleeping and the most used app is ANDROID SYSTEM. I look at SYSTEMPANEL and UNDER MONITOR HISTORY I can see that even when there is NO DEVICE USAGE, I still have around 15-30% CPU Usage (is this normal?). I also have it set to get email etc automatically.. some every 2 hours and some software every 4-6 hours.
What could be causing the battery drain? What is the best program to use to see the cause?
Im also not 100% sure SETCPU is using the screen off profile.. HOW an I tell this??? Any help would be appeciated...

Have you tried turning GPS off? If it's not actually being used, it won't drain the battery much or at all. However, if you're actually using it, it will.
If you're using navigation, that's a big battery killer, as it does constant GPS + a large amount of data transfer.
One thing you can try is to open Spare Parts, then go to Battery History and choose "Partial wake usage" in the top box. Things with partial wake locks are generally the biggest idle battery users.

that is the orde they are in and I set it to TOTAL SINCE BOOT.
And to answer your question about the GPS.. the only time I use the GPS is to get the correct weather for when I am, YELP and when I am in the car (and PLUGGED IN TO THE CAR MOUNT), GOOGLE NAVIGATION.
I also just Installed a BRIGHTNESS WIDGET and turned off auto-brightness. the widget I am using has 8 brightness settings and double click for auto. I am using currently on the second brightness setting on the widget (it shows little ticks). I am told lowering the brightness from auto will help...

I read in another forum that there was a bug in the Facebook application that was causing the application to refresh its information several times an hour instead of once in a while at specific times.It would use power and bandwith when the phone is even in sleep mode with screen off. They also mentioned that there was a fix already issued for this. I cannot find the link any more to source it for you where I read this.

My stock EVO runs for days with the radios turned off until I need them.
Sometimes, if it ain't broke ...

My evo has been draining fast without all that on and well it's annoying. The only compensation I have is owning 3 batteries.

I haven't seen that Facebook issue. One other thing. In spare parts I have activity management set to aggressive. Could that effect battery life or does that help battery life. I also notice in spare parts that I See programs that I don't use ruining that I didn't see before.

From your list I can only see two things I would kill these programs and wait and see what happens.
WUNDEREADIO
FACEBOOK
Everything else must run. For me Slacker radio kept my EVO on all day long eventhough I was not using it. The new version seems to fix that issue. I am guessing your problem is WUNDEREADIO. I would reboot (resets your battery information) kill Wundereadio. Then go to Settings, About, Battery and monitor your Awake Time vs Up Time. Write down the numbers. Turn off your phone and wait 10 minutes. You should see a gap in time. If so then it is Wundereadio.
Good luck

I think slacker and wunderradio were in the list because I just used them.. wunderradio inst in the list today.. BUT SLACKER is but not in the partial wake.. its in background ...
I changed my backlight setting from auto to using a widget that has 8 brightness settings and it is on the 3rd setting.. I dont know what the AUTO backlight was setting the screen at...
I also adjusted the MINIFREEMANAGER according to some settings I found online..
also I have SPARE PARTS set to AGGRESSIVE... would that have anything to do with it??

Check systempanel first thing when you wake up, but go into monitor, then history, and switch plot to top apps. It will tell you exactly whats been using the battery/cpu when there's been no usage.
As you know, the bt sucks a lot of battery, if you really do use it often, with a bunch of apps, you may want to consider tasker, which can be set up to turn bt on only when your on a call, or using certain apps.

Will tasker turn on bluetooth when a call comes in? IE will it let the bluetooth earpiece ring so I can answer it from the bluetooth earpiece?? also can I set tasker so that when get in my car, it will KNOW I am in range of a bluetooth speakerphone and it will turn on BT and connect??
I leave BT on all the time for these reasons....

Looks like tasker wont do anything for me with Bluetooth. The earpieces take too long to connect when a call comes in or I make a call and some even auto answer when they connect which I don't want. I wonder how much battery drain Bluetooth and GPS use if left on but idle?

Yeah, it would have depended on how long it took to pair. Still try checking the apps through systempanel after a few hours of non-use though. That should help.
And gps doesn't use much until its being used for something, but bt is a constant drain.

Double post

On my old tp2 Bluetooth didn't the battery much. I guess it does on the evo

OK so I have been running for the past day and 1/2 without blutooth turned on.. I only have 3G and GPS turned on. Still it seems the battery drains faster then it should. I look at SPARE PARTS and it doesnt show anything out of the ordinary on PARTIAL WAKEUP. I have SETCUP to 384/245 when screen off. I do use SYSTEMPANEL to look at what is running and it does show a LOT of stuff such as SLACKER, SOUND HOUND, JUICE PLOTTER, etc... what else can I do for battery life.. I left for work at 8:00 and when I got to work at 8:15, the battery was already at 90% without doing anything....
Aldo how much battery drain does BT take if I leave it on? its a pain to remember to turn it on when I get in the car and turn it off when I leave...

How to turn gps on automatically when opening navigation?

As for those who don't know. There is an app out there called tasker. It allows you to program all kinds of tasks and conditions.
I used it in froyo to turn on my gps automatically when I opened the navigation app. However in gingerbread tasker no longer works. I'm reading that in cyanogen gingerbread roms tasker can still enable and disable gps.
Does anyone know anything about modding EI22 so that tasker will work with gingerbread on our epics the way it does in the cyanogen gingerbread roms?
Is there a patch or a piece of code that can be taken from the cyanogen rom to allow this on different roms/kernels?
Possibly is there an alternative to using tasker to get the gps to turn on automatically when navigation/maps is opened?

Just leave GPS enabled at all times. GPS won't activate until a program needs it, and won't consume battery life while it's sleeping.

Cool. I kinda thought that, but I wasn't sure. I guess ill need to turn off location settings for all the apps I don't won't to access gps. I appreciate the info. Thank you.

To go with this, if the GPS icon is on the toolbar (generally a bullseye/crosshair looking icon), you're using GPS and therefore extra battery--on the flipside, if the GPS icon is gone from the toolbar, then GPS is in standby and not consuming battery.*
* I'm not entirely certain that it consumes no battery when in standby, but it's certainly much less than when it's active. As long as you keep an eye on which apps you allow to use it and when, the battery drain is negligible--At least until you use Navigation and forget to plug it in! Then you'll damn near be able to watch the battery icon visibly tick down, and might could cook an egg on the back of your phone, it gets pretty hot!

If you running ei22 stock, I can leave gps on all the time and don't need to worry about battery. But if you put in the gps fix, careful.

I hadn't noticed extra battery drain after flashing the GPS fix. I'll have to monitor that more carefully going forward...

The gps fix makes the phone constantly lock to all possible sats. Draining batts.

GPS is constantly "ON"

I have my GPS enabled. Half of the time I'm using my phone, everything is good, everything works fine. But during the other half of the times, the GPS is constantly on the notification bar. I try restarting my phone, still up there in the notification bar with a 'solid' gps icon which says "Location set by GPS"... I can even turn the GPS off, and then on again, and it still doesn't fix the issue. As i turn on my "Maps" app for the first time, my location is already "accurate to 3 meters" before it even loads the map graphics... How do i figure out which app is causing this, and how do i stop this? it's irritating. I have to constantly check my phone to make sure the GPS isn't active and draining my battery. And please, don't say "Just turn off the GPS". Android is designed to work with the GPS enabled. Even if the GPS is toggled "on", it shouldn't be using it unless it needs it, therefore using zero battery. (Just like wifi is supposed to). thanks.

I have the same issue and it seems like it's Maps that's constantly trying to turn on GPS. Once I have GPS off, my battery life is a lot better. Tried uninstall Maps, clear data, re-install...but the issue is still there but not all the time...very annoyed.

Another reason might be an app that is using gps in the background. Facebook, twitter, and other apps might be the problem?

If you have your google search settings on to make local search better, then the GPS will be on.
Facebook, Maps are all GPS hogs.
Just turn it off and on when you need it, the GPS on the S3 locks in seconds anyway, so its not a problem.

GPS ON or OFF?

i cant decide if i should keep my GPS on or off, if i keep it off apps like lookout will not work in case i need to locate my phone if lost, how do you keep your gps on or off?

On. Always.

on, all you are doing is allowing gps to run when needed. the only time it is on is when you see the location notification.

Depending on your other apps, GPS can either be a light nuisance (getting location takes an awfully long time) or a complete battery destroyer (apps which use the location feature too often.)
Definitely off, if you care about your sanity or battery life. "Battery saving" location option is more than adequate for most everyday tasks.

I always have my GPS off unless I need it.

I can't tell the difference on my battery life weather gps is on or off so mines always on

Keep your GPS on and in battery saving network towers option. If you have apps that look for location like a weather widget, they will actually use more battery trying to find location with GPS off than leaving it on.

What exactly is polling my GPS so much?

I know I can check settings>location recent location request....but I would like to know which app specifically is doing it.
Is there anything out there like better battery stats? It is driving me nuts, because even with most things greenified with xposed it is still doing it. Maybe its because I was used to also using amplify on my G3 but I never saw this finding location stuff so often!!!!!
I dont even know why I am worrying its not like I have excessive battery drain. I have a mugen battery. But I just want to know in case I revert to stock batteries.
Thanks!

Same thing. I went through and disabled every GPS using greenified and it was still polling frequently. So much that I just disabled the GPS completely.

weather widget
in my case it was the home screen smart card weather widget. removed that and the gps usage seems to be better. also you can set the freq of weather updates in the settings.
