So something strange happened this morning. I woke up, just like any other day, i took my phone from my bedstand to check my mail and such, only the phone was off for the first time since i bought it. The battery was drained. Thing is, I fully charged it before i went to bed.
Im running it on battery saver mode, no background data and i had the WiFi off on this particular occasion. Can someone explain to me what just happened. I checked battery usage and it said 65% being used by android OS.
Strange.
EDIT:
I also seem to be getting app crashes, can't access ringtone options and cant get into the native music app...
What is going on...

Can you try reflashing the latest SBF?
I guess I would ask the standard questions like have you recently installed any apps, been flashing anything or removed any system apps. First thing I would do is flash the new SBF update 198_7. This is provided by Yay 4 Juggs and is the official (leaked) update. Don't put on the update that is now out 198_6 cuz it has some issues. You'll find the update in the development section.

Ok, i got it sorted out. Apparently the battery calibration got messed up and that probably lead to the oh so common Android OS Drain bug. But i had it recalibrated and now it works like a dream again. All is good. Thanks for the help anyway guys, much appreciated!
Mods feel free to close this.
How do you do a battery calibration and what is it?
Thanks

Battery calibration is required when u flash new rom so as to remove the old rom's bin file containing battery stats..
Download battery calibration app frm market and follo2 instructions..
U can also do it via recovery..charge phone to 100 % and boot into recovery and wipe battery stats..

Lately, my phone has been using a very large amount of battery, I initially thought it may have been apps updating or running in the background. However, after checking the battery use, I noticed that the operation 'Android OS' had been chewing up 70-80% of the battery. In little more than 10 hours of standby time, the battery will go from full charge to dead. I have noted as well that this first started happening around when I updated the OS version.
If anyone could help me with resolving this issue, it would be greatly appreciated.
I've got the same problem and would like to know also.

Same problem here, too. As far as I know, no one has found a fix yet.

If you have access to wifi, use wifi and set smart action to turn off cellular data when on it. I go without charging for almost two days depending on level of use.

I had the blogger app installed, and once I uninstalled it, the android OS started behaving a lot more... Need to root this phone, get droid wall going to check what is really trying to access the internet... and block it!!!
Since installing apps such deep sleep battery saver and longevity I've had a problem starting everynight at 12am when phone goes into deep
sleep I lose WiFi and data I didn't have this problem prior to trying these apps I uninstalled them before I even noticed the problem tried reinstalling and setting things to disabled and uninstall again.
I have even wiped my phone at this point and I still have the problem..at this point I don't know which app it is i think its deep sleep battery saver since im pretty sure it started right after experimenting with that but I know I didn't have this issue prior it seems to obviously be on a schedule since it starts happening at 12
Another sign would be that it doesn't seem to happen when its on the charger which is another reason that would lead me to believe a battery saving app did something..now the question is how can I fix this especially if wiping didn't even fix it this is very annoying cause I rely on getting instant email notifications at all times and now I don't get them late at night if my phone is sleeping
ive contacted the deep sleep team through this site and contacted longevity as well to see if they have anything else to say..deep sleep was looking into it but im not sure what will come of that
any ideas?
anyone?
even if its a workaround for now..i tried keep wifi on type of apps still didnt work
What brand of phone do you have? If its a Moto, threres an app in the play store called restore connectivity for this exact problem.

Is anyone else getting Android OS around 50-60% battery use?
I have tried every ROM included going back to stock. I have ran the phone with nothing but Stock and no apps installed for a day and still get the same drain so I can only assume its a kernel issue.
I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.

I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals. I'm underclocked to 1350 and using powersave gov with deadline.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.
I can't speak for anyone else but FDT did wonders for my battery life. I was only able to go about 12 hours prior to disabling FD.

This is good for sure... it's just that compared to other phones, Android OS and Android System should not be that high.

^^^ This is indeed worth considering.... I think the question then becomes why is it consistent among the 3 roms we are using? Maybe when JB source is out and something is built from source all will be good.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.

Check out this thread: http://forum.xda-developers.com/showthread.php?t=1987032
before you reply, yes, i did search the forums first. all the posts were older and did not resolve the issue.
now, my device.
Galaxy Nexus 7 2012 - unlocked and rooted
CWM Touch Recovery
JDX 15.0 (JB4.3)
nova launcher
no widgets
yesterday i threw Jake's newest JDX on the nexus (clean install). today i charged it up to full. unplugged it and brought it to work. opened it up for the first time 2hrs after unplug and noticed i was already down 5%... normally, i can stay at 100% for several hours before i actually start using it. i can usually do whatever i want on the nexus and the battery is still around 70% by the time i get home in the morning. 8 hours after unplugging im already down to 52%. i could actually watch the % go down while i was reading. no media has been accessed since the install. mediaserver was using 89% of my battery when i first looked. after putting .nomedia files every applicable and then rebooting, its down to 38%. but to be honest this is a silly fix for a problem that shouldn't occur. unless i can figure out what's going on and fix it, im going to attempt to do a clean wipe and start from scratch.
i'd appreciate any assistance.
I don't have this issue anymore since I removed my sdcard. Media server was using at least 29% even when I wasn't listening to music, now it is below 6% when idled.
Still it sucks as solution but acceptable as long as I have enough internal storage.

Restarting your phone should fix it. Also, if that doesn't work, just reflash the ROM and that'll surely work
I did end up reflashing the ROM, but before I did that I added the .nomedia files where I could, so I will never know what was doing it. So far so good though, sitting at 2%. Thanks for the quick replies.
