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...
i ran these through my seat-of-the-pants benchmarks, are there any other for these sorts of apps? , and can't tell any difference. the biggest difference maker that i have noticed is Titanium backup and freezing as many progs as i could and a better launcher.
i tested the phone as it initially came out of the box, removing the apps i could via app manager.
next, i ran it with JDU for ~4 days.
Then i ran Tit backup and froze many more apps and ran the phone with JD for 3-4 days.
then installed Ram Manager Pro and ran for a few days, then uninstalled JD and Ram Manager by itself for a few days
and finally uninstalled both, factory reset my phone, ran Tit Backup freezing everything i wanted and am now running that config for several days.
i can't see any change in battery life or perf between any of these.
what's your experience? did i miss the benefits? is there a more scientific way to test these apps on our phone?
I could be missing something, but my understanding of Ram Manager is that it controls how the cache works (RAM cache that is), aka, how previously opened apps are being handled, how long they stay in ram, or/and how often ram getting cleanup, etc. So theoretically there shouldn't be much of battery improvement with that app, only the performance on common used tasks.
As of Juice Defender, I've tried once, and realized it's not for me, I use push mail and listen pandora radio most of the time, it requires internet all the time. But in theory it should significantly save on battery if you don't use phone every second minute, cause it turns off everything and only turns data one every so often to check email, news, etc.
I guess it depends how you use your phone...
Have you tried SetCPU or such?
I use SetCPU to change CPU frequency, set min to 190mhz and max to 1500mhz, and max to 190 when screen off, yesterday with minimum phone usage in 7 hours used up 15%
And I wonder, by default, does Nitro set CPU to max and keep it that way or it also uses scheduling and changes speed as needed?
But I can tell you for sure, the network (HSPA+ here) usage uses as much battery as the screen, if not more...and network through WiFi saves on battery compare to HSPA.

that's my understanding of Ram Manager as well. but i didn't notice any perf changes in how fast apps open, close or switch v a Titannium freezing showing good results imo for that sort of thing.
i listen to slacker/pandora but it's mostly via wi-fi, so i was able to configure JD to keep the wifi on and turn off all the other radios but that didn't seem to provide me any benefits.
i have not tried setcpu but will def check it out, thx for the heads-up on that one.
re: network, it doesn't even show as a battery drain on this phone and i am in an LTE area, the 4glte status signal is always on. i was under the impression it was a massive drain, maybe the phone searching for a lte signal is the drain but once it finds one and locks on maybe it settles down. i have no idea but it's not on the list of what's using the battery.
Ram Manager Pro has several settings (Balanced, Balanced-More Mem, Hardcore Gaming, etc...). Did you try any of the others? For me I noticed improvement, but perhaps it's also because of the way I use my phone and that Ram Manager is more suited to my ways and habits... Or maybe it's just placebo and I'm drinking the kool-aid.
For Juice Defender Ultimate, I will say probably one of its' biggest capabilities is locking down the apps that turn on the radio for background updates. A definite battery drain for folks that use a lot of social apps as they compound the use of background updates. I personally turn-off ALL background updates except for mail. So JDU wouldn't tremendously help me.
Lastly, I completely agree with [email protected] about SetCPU. I don't know how the OS handles the frequencies but one of the biggest battery savers is definitely using SetCPU for dropping the min/max CPU speeds to minimum levels when the phone is sleeping.
I installed setCPU and it instantly created a laggy interface. very very noticeable. HAs anybody else tried this app with this phone?
Had this same problem. I actually switched of all apps. The phone on idle does not loose that much juice. Overnight I maybe loose 8-10%. I turn data off at night using Tasker.

update
I've still been farting around with these apps, going back & forth between using them and not.
best I can tell ROM manager provides ~5% increase in ROM management, which is pretty good for a couple bucks eh.
JD is so much harder to gauge/compare. I think it does defend the juice but I can't tell how much. The one thing I do not get about the app is how it continues to show increased battery savings over the previous 48 hours. I can see how this works when the app is 1st installed but at some point over time that number should = 1 right? JD can't keep stretching battery life 1.5x over its own management system.
scott0,
You're right, unless there's some heuristics built in (probably not).

Anyone using a good stats widget that would show mhz of cpu/baterry/ram?
Something light that would not eat battery. I used the one that came with antutu cpu master but that caused more problems.

Just out of curiosity, do you have to be rooted to use Juice Defender? When I select the app in the market it tells me "This item isn't available by your carrier."
Are they telling me that AT&T has blocked a power saving app?
I recently installed CM7, Afterwards my battery life is very low, At night I had about 84%, but at the morning it became 22%, Its very annoying. What should I do?
Another Problem, My phone doesn't even play 360p videos fluently after flashing CM7. It plays the audio first, then stops, then plays video, then audio,
I also tried MX player, Still made no progress.
Please help
To answer your battery problem, make sure you quit apps with the back button and not home. Check what apps are running in the background. Turn off GPS, Wi-Fi, etc.

Yea, I did that, And is juice defender effective?
Turn off auto-sync (Eats up a lot of battery). Remove unwanted apps (the ones that run all the time. Not games)
And I have never found juice defender useful. I never use battery-saver apps.
I didn't like juice defender, i bought the paid version then decided it wasn't for me, the best free App for switching things off when you're not using your phone is llama imo, it's relatively simple to get it setup to turn off data, wifi, gps and even kill apps when your screen turns off and then turn everything back on again when you turn the screen back on.
Also there is no need to uninstall anything that runs in the background constantly (Google maps for example) and cannot be killed by any task killer, all you need is an App called autostarts which will break the flags any App needs to turn itself on thus ensuring you have complete control of what is running in the background. All you have to remember is to close an App properly after use otherwise it will keep running.

Battery life sounds good to me, considering its a 1300 mah battery. But reflash the rom and see if the vedio/sound problems go away, if not its a bug in the rom. Hope this helps
Under/Overclock
If you go to Settings > Cyanogenmod Settings > Performance > CPU Settings, you can over/underclock your processor, which can help not only with battery, but with performance! Basically, set a governor (Smartass is probably the best choice for most users) which controlls your CPU frequency, the limits of which you can set below. Personally, I use 245-748 MHz, but you should try increasing/decreasing the settings from their defaults one by one, then stress loading, to see where you can get them without stability loss. These settings have led to a battery life that's somewhere between a full day and almost half a week, depending on how much I use it. If I just leave it overnight, the battery percentage shows no battery loss, but keep in mind that's with Autosync disabled. Also, if you have no need for instant notifications, try using the Data On/Off in the Power Saver widget, turning it on or off as you require data.
Hope this helps!

I would certainly recommend llama.. i read scratch recommend this in some of the threads.. i started using the same and am quite satisfied.. kudos to scratch
Hi, Ive been reading a lot about battery saving apps that I started to get curious as to whether these apps really work.
I installed JD out of curiosity and I have to say that all it doea is disable automatically your phone connections to help you save power. Things that you can actually do manually. Like turning off wifi and mobile network. If im not mistaken you can disable mobile network under your phone's settings.
So my question is, if you can do it manually, what is the point of apps like juice defender? It eats up ram and runs as a background process which in my opinion does more bad than good to your battery unless your the i dont know how to disable connections manually in my phone kind of guy.
Somebody please enlighten me. Thanks.
I have used it for a long times. Since I used Xperia PLAY.
I think this program is good. Yes, if you can manually do it. But the feature I like the most is Screen. It can change CPU ghz according to your screen on / off.
It saves my battery a lot.
Press THANKS if you agree with me.
I am a long time user of jd but these days the only feature i use regularly is to disable data overnight.

- Airplane mode over night
- automatic wireless connection with "location" feature (if near a known wireless network it starts the wireless and connects, if not near it directly starts 3G)
- I do not have to mess with on/off wireless/3G
- automatically syncs every hour, so I have to do nothing but still get my mails
- with rooted phone underclock on screen off
- bluetooth off after 5 mins without connected bluetooth device
etc....
It is NOT for you if you want to have online connection all the time. And it is not for you if you don't mind to do all the things manually it does for you.
And in my opinion only the full version really helps, the free version does not much...
I think it's a great app! :good:
If you just need to auto toggle data, check out 3GBattery too.
https://play.google.com/store/apps/...wyLDEsImNvbS5teXN0aXF1ZS50aHJlZWdiYXR0ZXJ5Il0.
basically, there are 2 main things that drain our devices: 1) 3g/2g and 2) display brightness. I've been using JD since ever, and the difference is awesome with and without. Even the free version is enough to save some batt, in the Agressive mode (connects every 30min).
Besides JD, I am using Greenify. Which needs root to work and does a beautiful job with background apps like Facebook, GMaps etc.
works on both my devices :good:
Personally I think this app is useless.
As OP has said, you can just set up those things manually.
This app just eats RAMs and use your battery up more.
Kinda a similar concept to hot plugging the CPU from 1 core to 2 cores. What if there was a feature that would hot plug data. I've been turning my data on and off manually as needed and of course there is a very noticeable boost in battery life. But if say the kernel could just turn data on and off every 5 min or whatever, you could half the time the radio is on increase battery life and still be able to receive updates with apps that require a data connection. Just something i thought about while i was driving. Not sure if its even possible but we have a toggle so it should be possible to write code to toggle it back and forth. Thoughts anyone?

Check out Deep Sleep Battery Saver on Play store. It allows just what you are talking about as well as killing all running apps when screen is turned off Fully customizable.
Neat. Ill have to check that out. Thanks!
