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.
Sent from my blah blah blah blah
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...
Hey guys,
This has been bothering me for a while now, but on occasion, my phone just stops sleeping. I attached a screen shot to show what I mean.
It happened on stock, so I've tried a couple other kernels, but they have the same problem.
Any suggestions?

Yes, probably you're experiencing the "AndroidOS" runaway issue. This is a nebulous and currently unresolvable issue, probably related to some Samsung/Sprint driver issue(s) causing feedback loops between the events/0 and suspend processes. It seems to be fixed temporarily by a reboot, or just randomly. It may or may not be associated with excessive battery usage.
I used to get those solid awakes, but then I froze a lot of apps and it went away.
I didn't do it systematically to figure out which was the cause.
As an aside, if you have an older version of FlightView, then that could definitely cause the issue. That isn't a stock app, but is somewhat popular and had a bug keeping the phone awake *even though it wasn't configured to do anything*.

Ironically, my AndroidOS has always been high (almost always higher than display), but it would always sleep just fine, and my battery-life was pretty good. But every time this happens, my AndroidOS is actually lower than usual.
So I've temporarily disabled Juice Defender (just in case it was interrupting something and confusing it into holding a wake lock) and removed the Facebook widget (Better Battery Stats had that listed as 50% of the wakeup events, which is just ridiculous).
I set a custom reference point so I can watch it for a while and see if anything weird pops up. It seems to be happening more often in the last week or so, and the only thing I did back then was remove Watchdog, because I haven't gotten any alerts for about a month.
I have noticed that usually when it gets stuck in an awake state for a long time, it also coincidentally has a stealth LOS, and rebooting will magically cause texts and voicemails to appear. Let's hope the December radio update fixes that problem.
All I can find are vague descriptions. Nothing saying what exactly it's doing. From my experience thus far it's doing nothing. I am not getting better battery.

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.
I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

Mine only does that under 15% battery. Seems like its doing nothing over that.
Sent from my LG-H815 using Tapatalk
The default is under 15% and when it kicks in, i definitely notice a difference in the phone.
You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.
Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:
I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.
Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.
So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.
Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.
It saves battery

yup..i feels like the batrey saving mode is draining more batrey life than not using it..is there a solution for this ?
I'm happy with the Note 5 but I've noticed a problem with it I cannot figure out.
It seems there's some sort of application that keeps causing a "notification". I've made the default notification sound to (none) which stops it (since I can't hear it ) but whenever I'm at work if I put the phone on vibrate or mute the phone every couple of minutes will vibrate. I go to look at it and there's nothing in the notification shade. Where do I go from here to try and figure out what application is causing this? I get good battery life with the device. I don't see any crazy tasks eating up resources looking under battery settings.
What systematic way is best to try and hone this down?
If u have Greenify installed watch it close apps when screen is off. Screen will flash on lightly.

Check out this thread, this happened to me as well, until I remembered the accessibility setting:
http://forum.xda-developers.com/att-galaxy-note5/help/random-default-notification-t3234394
Yes this was the fix, it drove me N U T S for well over an hour.
I know this will be almost impossible to solve with suggestions, but some of my notifications don't come through until I unlock my phone. Most notably WhatsApp. I've turned off all battery optimisation options, removed it from the sleeping apps list, allowed background data and turned off data saver. Still have the same issue.
I have naptime installed so turned that off as well.
What's strange is that a few days ago all my notifications started coming through as normal for a few hours, and then stopped again.
I know the only way to solve this is probably a factory reset, but with loads of tweaks I've gotten it so my battery life is amazing. Leaving it overnight it drains around 3% and depending on how I use it I get around 8h of SOT with 50% battery left so I don't really want to factory reset.
What launcher are you using?
I feel your pain with factory resets.
There needs to be a backup settings to cloud so you can easily restore them after a reset or even a change of phone.
I understand your frustration with this issue, I experimented it as well when I started using my device, back then I did not fully knew about all the battery optimization settings, but, when trying to get all the notifications right, I stumbled upon an app named PNF-no root, which is meant to fix the push notifications from sms, email, whatsapp, etc, I tried so many things, that I honestly can not say if this PNF solved the issue, but in the end my notifications became normal, so, I kept using it, you can give it a try, that is, before you reset your phone, it might help
Do you at least move your phone? Because a lot of apps, to bypass the system's optimisation that put apps to sleep, is that their wake up workaround is gyroscopic based.
That's why WhatsApp and such use a lot the sensor while it has nothing to do about in the first place.
If a battery monitor works for you, you can check that for WhatsApp.

I've just installed a push notification tester app and my phone goes into doze immediately once I lock my phone and the screen turns off it seems.
If I request a notification, it comes through with the phone unlocked but if I set a delay of a few seconds and lock the phone before it comes through, nothing will happen until I wake my screen up.
Any ideas on how to solve this?
I worked out what the problem was!
I have a VPN that is set to disconnect when my screen turns off to save battery. At the same time I enabled the Android setting that blocks all connections without VPN. Of course when the screen turns off and the VPN disconnects, my phone was blocking all outside connections, hence me not getting any notifications.
Well, I am glad you figured it out
