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.

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

Click battery history, then click where it says Other usage, change to Partial wake usage, this should tell you what is using your battery while its asleep.

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.

How-To: A possible solution to battery life

So several people have started to notice that "AudioOut_1" wake lock might be polling our batteries unwillingly on our part. So I decided to go out and disable everything that could make sound except for the ringtones and notifications themselves since we all have to have that. This is what I came across...
---------------------------------------------------------------------------
Settings > Sound
Uncheck "Touch sounds"
Uncheck "Screen lock sound"
Profit.
---------------------------------------------------------------------------
Just went an hour without losing 1% battery after I did this.
Some people are claiming they only are losing 1% or less per hour now, just leaving the phone sitting not doing anything. So this may be the temporary fix for the phone being awake when it doesn't need to be.

Seems to be 50/50 on this

Ive had those off and I am actually going to run my phone in vibrate only mode for a while and see what results from that.

this has little to no effect on battery life. Look at your Android OS battery consumption before, and after. It will be the same

Biggest solution I've found for battery life is disabling my GPS when I don't need it, and going to CDMA rather than LTE/CDMA. They're still there for me when I want them, but most of the time I don't need them.
Right now I've had the phone off the charger for 4 hours where it was topped off; I'm at 91% now, with moderate use (Google Currents for half an hour, about another 20 minutes total screen-on time doing other dinky things, three texts)

First of all, disabling GPS will have absolutely no affect on your battery life. The GPS is only enabled when an app calls for it, if you don't have Google Maps open, then your GPS won't be engaged.
And turning off the sounds will have little to no affect, it's the vibrating that kills your battery more. Turn off haptic feedback, turn off vibrating notifications, turn off vibrate on key press for the keyboard.
Oh, and staying connected to wifi is much easier on the battery than using data. On wifi your phone doesn't have to keep polling the cell towers for signal

Turning off GPS works for me because I often use social apps (e.g. Facebook) that engage GPS for their 'check-in' features. It may be a minor thing, but having turned the GPS off, I've seen real results. *shrug*
Also, maybe a gimme for you smarties, but I disabled VZ Backup Assistant.

Yes what you are saying has made sense in the past for Froyo and GB but we are having some sort of unknown wake lock and this seems to be the biggest one. Ever since I have disabled both of those features my AudioOut_1 wake lock hasn't awakened the phone ONE TIME.

I had a custom rom with dreadful battery switched back to the latest stock and have noticed the following: When you have good signal the screen on and awake seem to match up, i only lost 30% in TWO DAYS! then suddenly when i went out to the country side today i lost the remaining 70% in only a few hours seems that when the phone has low signal is is almost ALWAYS awake. I understand that in lower signal areas the phone tries harder to get signal but surly it shouldn't be awake like 90% of the time!

my top 1 was some sort of googlephotos sync service. i might turn off instant upload with google+.
that audioOut_1 was at like 1.2%, turned off these 2 settings before i unplugged from charger

Yep that is another major contributing factor to terrible battery life. My phone will drain VERY slowly in good signal and die rapidly in bad signal.

[Q] Battery Drain Issue

I am trying to troubleshoot my battery drain issue so I have been inserting a fully charged battery into my Note 2 just before bed.
Stock 4.1.2 ROM
Rooted
Night 1
Before bed: 100% battery, airplane mode
Wake up 7.5 hours later: 100% battery life
Night 2
Before bed: 100% battery, WiFi connected, background sync enabled
Wake up 7.6 hours later: 54% battery life
I have Greenify and BetterBatteryStats and still can't figure out what is sucking down the power.
Sync Interval:
Twitter: 4 hour
Facebook: 30 min
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Any help would be appreciated!

I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it

Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following
Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.
NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.
Things I am going trying.
Freeze Samsung Push
Freeze ChatOn
Greenify Facebook

You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:
1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail
etc, etc.

I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?

Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.
I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.
I need to find which apps are using WiFi so heavily.

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.

Try backing up all ur data on internal and SD card.. Then do a complete fresh install.

Battery Life - Idle drain?

I was wondering if anybody else had this issue or had any suggestions.
Battery life is normally great on the tablet, except every once and a while it gets stuck awake overnight. There doesn't seem to be a 3rd party app that is holding it awake, as Android system and OS is what's using most of the battery.
As you can see in the screenshot, Doze works fine and barely any better is drained, I used it briefly, came home from work and half the battery had been drained.
Thanks for the help

Not sure if it's normal but mine does the same.
Sent from my Nexus 6 using Tapatalk

I've seen a 30ish % drain sitting overnight a couple of times over the past 2 weeks. Can't seem to find a rhyme or reason for it.

I can't imagine it being "normal" since, with Wifi set to off while sleeping that the device should drain that much.
It's odd and happens randomly, I'm on the same page as you bluestang.

It happened to me once, at night it wastes a 15% battery.
I changed in wifi advance options to not maintain WiFi always awake, only in charge.

That's the setup I have though - so I get no notifications or anything when it's not on. Yet something is still keeping the device up.

I have *exactly* the same problem with an all new device, and with nothing but a game installed on it. After a reboot, if I let the Pixel C right there for a night, then it only drains ~3/4%.
Then I play the only game I have for 5 minutes, and let the device again for a night => it now wastes a 20% battery!
No idea what's going on... "Android OS" appears first in the list of app, but this does not help me so much to find what is actually happening...
The issue still appears even after a full reset of the system (I'v tried, without success).

Exactly. If I reboot the device and let it sit, doze works fine, the second I open an app, use it and put the tablet down, something hangs and keeps it awake. Always Android OS that is keeping it awake as well...

I'm on stock - not even rooted

I'm on stock MM here as well.
Also, not sure if it a coincidence or not, but I changed this and haven't seen overnight battery drops anymore. In Settings>Location I changed the Mode from High accuracy to Battery saving. Since the Pixel C doesn't have GPS device, then why use it.
Like I said, not sure if it a coincidence, but battery life has been great overnight since.

So last night, I rebooted before I went to sleep, but overnight the battery drained from 85% down to 57% in about 8 hours.
I decided to check my location settings as per your post and found it was set to high accuracy, so I changed it to "Battery Saving".
I did nothing else(no reboot) until I checked my battery now about 3 hours later, it has only dropped by a further 2%.
Looking at "Battery Monitor Widget Pro" history statistics, it is clear to see that overnight the battery was draining considerably more.
It takes readings every 10 minutes and was showing between 450 and 275 mA being used every 10 minutes overnight.
Since I changed the location settings, most of the time it is 15mA with occasional jumps up to a max of 297mA.
Although this could not be classed as conclusive proof, it does seem to have had an effect, I will keep monitoring it to see how it goes.

Yep, I change that setting on the 19th or 20th and haven't seen any major drains overnight.
I think I may have found a winner with that little tweak

So far so good for me too. I don't know if it is related to the GPS settings, but no more inconsistent major drains so far.

if location services is on it can drain a good deal

Just to add that I had exactly the same issue on stock 7.1.2, tablet was staying awake and draining. Reduced location precision and now only a 2% drain during an 8 hour sleep which is a massive improvement.

Doubts about battery A5 2017

Hi, I have doubts about the battery or need advices.
When I go to sleep at night and wake up in the morning (6 - 7 hours), the phone drains about 15 - 20%, is it normal?
When I go to sleep I put it in mid power saving, 80% brightness, wi fi and AoD activated, blue filter activated, auto brightness checkbox deactivated and in settings -> maintenance I erase RAM.
Even though, the battery lasts 36 hours or more.
Thanks in advance.

That's normal standby for most devices, though I don't really lose as much percentage overnight by just closing all apps before I go to bed and keeping the brightness low while leaving WiFi and Location Services on. I go to bed with 60% and wake up 7 hours later with around 50%, so maybe you're doing something wrong. But 15-20% overnight isn't really a big deal at all considering how fast this phone charges.; you get 20% back by charging for just 15 minutes. You'd really over ever notice a difference in standby time if you're coming from an iPhone which has the best standby time in the business, but this phone makes up for it just fine.

I knew for sure that my battery life increased exponentially when the phone started dozing apps I didn't frequently use. The phone hibernates apps after 3-7 days of not being used, but you can put them to sleep yourself in Device Maintenance.

Advice
I lost just 1-5 at the night I stop AoD,and wifi if you use Facebook app or social media apps will drain battery faster than when using browser it's better.:good:

Only 1-5% ? Amazing. Yeah, but if you deactivate wifi, you won't get any notifications of anything during the night (if you think about it, you won't answer any because you are sleeping). Maybe I'll try that.
I don't use Facebook too much, but the browser version is a bit slower and not comfortable IMO.
The principal app that drains my battery is the PvZ2, though.

It will disconects wifi even when you turn it on... I lose abou 2 to 3 % night, but I dont see point of having device on during night so now I power it ofd

Instead of turning it off completely, you can also use the maximum power saving mode. Using that, I went to sleep with 97% and once I checked after waking up it was 96%.
I didn't measure the boot time of the device (not that I even care about it) but disabling the power saving mode might be a bit faster than turning the phone on.

Thanks all of you!

It is NOT normal for battery to drain 15-20% overnight.
Normal drain in that period would be 1-2% without AOD and 4-5% with AOD.
Battery wise A5 '17 have good one. I usually get about 7 hrs on SOT with medium ussage or 1.5 days ussage.
