[Q] Any clue what is draining my battery? - EVO 4G Q&A, Help & Troubleshooting

So who can tell me what is sucking my battery down to the tune of 20% in an hour? CM7 on my EVO with Savage Zen kernel. There is a greedy app somewhere. The cell phone standby seems way too high. My baseband is 2.15.00.11.1. Any suggestions?

Well for one thing, maps shouldn't be that high on the list. Do you press home or back to get out of maps? Its chews up the battery quick if it runs in the background
We're comin from a pure power source.

Do believe that I'm pressing back to exit it. I leave my GPS on, but it shouldn't be consuming anything unless I'm using something that accesses it. I have location in Maps set that I'll update it manually.
Someone on another forum suggested resetting battery stats, running it down to zero, then charging it a full cycle.

That's exactly what I did and it seemed to work wonders... You can wipe your battery stats through any recovery process

I tried that so I'll run it down to zero and see how it behaves tomorrow. Otherwise I'll do a factory wipe and fresh install and see what happens.
Thanks!

Your GPS and your Mobile Data are HUGE drains. Use the toggles to keep those off unless you need them on, and only when you need them on.
Leave your WiFi on. It uses very little battery.
Also, do the battery conditioning technique after you get to full charge.

[Q] missing processes for battery usage

Hey guys, very new to the note 2 here and after I charge to full I only get a few items showing up when I go to
Check battery usage. Gsam shows everything fine but I'm wondering if anyone has any insight on this. It has happened on both Clean Rom and SkyNote. The last time it only showed screen and idle. I wiped and reflashed but it still happens.

It wipes it all when it's fully charged. Try running it down to like 60 or so and see if any other apps show up. My guess is that they are just taking up less that 1% battery over the 3 minutes

Alright I'll let it run down, but it's weird cuz android OS and System are never below 1%, they're usually always there. On Gsam they are showing up. Xda app is there too at 13%

Alright so I found a few threads with the same issue of different roms/phones unfortunately no posted resolution.
Tried wiping caches fixing permissions, uninstalling apps, reflashing the kernel. Nothing had worked until I reset Perseus kernel to default settings and rebooted. Soon as the phone came back I was able to see 8 or so processes and apps were now there like usual.
My settings are back to how I had it before all this started so we will see if it happens again

@ speghead, Yikes, I just lost all items in my battery usage screen except the main graph and hope I don't have to bomb my phone back as far as you did. Will try full drain and full charge first. What other threads did you find for this issue?
Edit:
D'oh! The per-application battery stats came back at the next full charge. On thing that can throw this off is that some battery meters report 100% at a point when the android system does not yet consider it full and if you stop charging at that point the stats may not refresh.

Google maps draining my entire battery

Since about a week the battery life of my one X has become terrible. According to the battery usage screen, google maps seems to be draining all the juice. Im not actually using gm though, so something must be going on in the background.

Does this sound familiar to anyone and is there a solution to the problem?
Thanks in advance!

Just disable it

And how do I do that? I can close the process, but it will automatically go back on. Disabling the app itself is not something I know how to do and not really something I would like to do either.
Perhaps one other thing of importance: when I open maps (or now) it says location services are turned off, while they are not.

disable from settings app manager OR
get greenify from playstore and just greenify it
problem solved :good:
Also, where do you live at? Might be your not connected to the right sattelites for your region. You could go to play store and download faster fix and make sure your phone is reading off the right satellites.

Wakelock, better battery help

So I feel like since I rooted my phone and installed nova my batter drains more...and I'm really new to all this stuff and I don't understand what any of this means:

That's not normal. Whatever wakelock is keeping it awake is not captured in your WLD screenshot. Track it down in better battery stats instead, using "partial wakelocks"
Thank you...that's what I thought... I don't know what happened...so I went into partial wakelocks and everything looks like low %... But kernel wakelocks there was a lot of high percentages...
First thing that sticks out is drop box. It shouldnt be running for that long. Did you turn on auto backup? This will cause huge drains. If turned on turn it off. Also check in service running for 21 minutes... Turn off your gps. This is Google now constantly running and locating you to try and provide you with what it thinks is useful cards (weather, traffic, food in your area) I only then on my gps when I'm gonna use navigation. Otherwise all apps with gps access will start to run and kill your battery. Also I suggest greenify. It'll help a lot with things like Facebook, Twitter, Google search, ect. Wakelocks. Also removing or freezing bloatware helps tremendously with battery drain. And last carrier iq. Something that always runs in the background. Google search it or read up in the battery threads here on XDA. They talk about it a lot and how to try and stop it. Also this thread

although for the SGS5 it can be applied to our device as well

Android system 4.4.2 killing battery

My Galaxy S III battery drains very fast, sometimes as much as 10% in 30 minutes (running 4.4.2). The battery is fine (I did the spin test), so I'm pretty sure it's a CPU-related issue, especially since the battery temperature is always around 110 deg F. The Android System process uses up more battery percent than my screen, so I did a full reset, ran DU Battery Saver, disabled LTE/sync/wifi, and uninstalled over 100 bloaty system apps through rooting. Still, even with a fresh install and all the other adjustments, the Android System is sucking down the battery juice like it was before.
I've been doing tons of research on this issue and haven't been able to find a solution. When going into the show CPU usage through developer options, the top line (with all the numbers) is often showing a long red line (even after doing a full reset on the phone).
Any suggestions would be greatly appreciated. Thanks.
Not CPU related. It's an app hats continuously running in the background. Try Wakelock Detector to find the culprit.

You mean a system app running through the Android System process?

According to Wakelock Detector, here's the top culprits from the kernel wakelock menu (after ~5 hours):
PowerManagerService.Display (~43 min, x53)
main (~43 min, x53)
PowerManagerService.WakeLocks (~26 min, x1428)
bam_dmux_wakelock (~20 min, x797)
Thanks for your help so far. Where do I go from here?

I checked and it says I use 2.4.....
Hmm, i guess you have checket others battery drain apps etc, i dont use facebook and messenger on mine..
You can try a full reset on it sometimes that helps. (Iknow it sucks to set it up again)

Ok, you could try root it again and try find the best battery calibration tools around, then im out of suggestions for now
