My N7 LTE have these 2 wakelocks (based on BBS) that kept draining my battery:
- suspend_backoff
- qxcom_rx_wakelock
These caused the "Android OS" USAGE to go about 38% of the battery life.
I used Greenify and AutoStarts to disable the same applications in the N7 as my S4 (Amazon AppStore), so it seems to be something specific to the N7 LTE.
There no way you can get battery life as posted by the WiFi only users in here:

Wowzers - battery life!
Stop the presses! LTE uses more battery than wifi! The world must know!!
Also, I don't have these wakelocks on my LTE version.

So your N7 last only 12 hours?
If no, then help those who have battery life. Otherwise, we don't need your sarcasm.
This is my first LTE Android tablet. My other one is an iPad with cellular and I have great battery life.
LTE and the "great battery life" are incompatible.

Isn't the above is what I am trying to point out in the thread title?
I think most people know battery life is bad, but I just want to point out that it is REALLY BAD.
12 HOURS with just 2 hours screen time.
If I am wrong and you all get better battery life than the above, please enlighten me, especially the issues I had above.
By the way, my S4 Active, a PHONE, have far better battery life than the N7 LTE.
Yes LTE uses more battery than WiFi only, only logical since it's powering extra hardware.
Mine seems to last quite a bit longer than that. Sorry I can't check for wake locks since BBS is not yet working under KitKat.
With just built-in battery state, I'm currently almost 14hrs since charged, got around 1hr screen time and still got 78% battery left.

I think the LTE version does consume a bit more battery.
Here I use the EDGE network. When in standby status, the battery power drops usually 1 percent / 2 hours. Something like that. It was for 4.3.1, not the 4.4.
I've heard 4.4 is far more power efficient.
Mine usually last 36 hours on a charge. Currently it has been up one day and four hours with five hours screen time. Playing videos and playing poker used most battery. I am sure many people have similar stats.

Something is not right on yours, Android OS battery usage is at 12% consistently on mine.

Same here. Unreasonably terrible battery life for LTE. I expected a little more. Upgraded to 4.4 also.
Are we all talking about the same device? The 2013 Nexus 7 LTE? I get EXCELLENT battery life from mine. I've never had an Android device last this long. I could go up to 3 days without having to recharge. I usually put it on the charger every two days. See my snapshot:
I bought the LTE version because I wanted LTE connectivity.
Thanks to everyone who shared their battery life. So something is causing these wakelocks and shown as "Android OS".
Interestingly, I do NOT use many apps that use background processing, such as Facebook, Instagram, weather or even Google Now.
Quick question: do you guys use ANY anti-virus/malware application? I use Avast but because I want the FIREWALL capability to block app or games from making Internet connection, since that will eat up my data. These apps/games usually connect to download ads and they're built-in, which Ad-Away CANNOT block (per the author).
Other background apps I use are "normal" apps --> calendar, 3 Gmail accounts, Google Contact Syncs, Google Talk. I use Greenify too.
If you guys do NOT use anti-virus/malware application, let me know. I will try uninstall Avast and monitor my battery life tonight to see if the same wakelocks appears again.
BTW, those who use BBS, do you see excessive usage of these wakelocks:
- suspend_backoff
- qxcom_rx_wakelock

Oh? Looks like you have the same issue as mine: High usage of "Android OS". If you're NOT on 4.4, I'd have ask if you can use BBS to check what caused this.

I'm not a fan of social media, so I don't have Facebook, Google+, Instagram either. I do not use any anti-virus applications. That may be one of your battery drainers. My Nexus is bone stock and still on 4.3. I don't know whats BBS or a wakelock, so I can't help you with that. I just use my nexus for browsing web pages using Dolphin and it's Jet Pack to block ads while surfing. I also use the WSJ (Wall Street Journal) apps as well as apps from my stock brokers (Interactive Brokers and Tradestation) to keep track of the markets. I do use Google music to stream music in the car using bluetooth.

BBS is Better Battery Stats. It was created by one of XDA member and available here: http://forum.xda-developers.com/showthread.php?t=1179809. The app allows you to drill down and see a particular process causing the battery drain.
I have uninstalled Avast and will monitor the battery tonight. Will leave it ON, unplugged, CONNECTED to WIFI and not used. Let's see what will happen.
PS: Any good firewall app I can use to stop free apps from downloading ads? For example, I played Tiny Death Star and that app uses about 10 Mb of data in 1 day...and I only played it 3 times!
I had the 2012 Wi-Fi/3G model and it too had terrible battery life. I don't mean while it was using the cellular radio only, but on Wi-Fi only the battery life sucked. I pulled the SIM card out and turned off the Wi-Fi too, didn't help at all. I know the 2013 N7 does have a smaller battery compared to the 2012, but I feel the 2013 Wi-Fi only version gets better battery life than the 2012 Wi-Fi only version did. Yes, I had 2 N7s last year.

Hi guys, I have N7 Mk2 LTE version.
If I don't play games, it keep 2+ days without charging. So stop writing all the bull...t above.
Before you write some nonsenses about battery drain, try to uninstall Facebook app...
Try switching to Samsung Note 8 and you'll thank that N7 LTe has more battery life. Been there and never look back since I switched to N7. Awesome battery life, last to 2 days and perhaps 14-16 on normal use with a bit of short gaming.

As you can see I've got hardly any screen on time. Location services, GPS, sync and everything were off. Data off. WiFi on but had strong signal entire day. Battery saver on. Not rooted, full stock.

CarrierIQ! You probably have it enabled. Given that your screenshots say AT&T, this is most likely the culprit. Disable it and your battery issues should go away.
I've read people across devices have been getting drain from Google Play Services. Seems it would show up though, it's the 2nd thing in mine next to screen...

I don't have that issue. My Google Play Services only takes up 2% of my battery. But its a known issue that if you have an AT&T phone, chances are you accepted everything when you first setup the phone and opted into CarrierIQ.
For the OP, his screenshots don't see Google Play Services as a battery drainer. I am pretty sure it is CarrierIQ draining his battery especially if he has GPS enabled all the time.
Battery usage was included in screenshots.
Carrier IQ uses that much battery? User has to opt in to it?
Guess an FDR is in order to opt out this time. Save you stuff to your PC or cloud first.

User opts in when they have a pop up window asking if they can collect locations statistics and send it back to Google or whatever for assisting in resolving issues. I don't have AT&T so I don't have the exact popup handy. I just know that Tmobile has an setting in Options to disable CarrierIQ.
I don't have GPS on ever. And I can't find carrierIQ anywhere. I'm not familiar with it.

Wouldnt that be a wakelock issue? look his cell standby takes up the most of his battery... check out GASM battery so you can know what to disable to save battery
Google Play Services has been killing me over the past few days and there have been a LOT of reports of others having the same issue across multiple devices. Today Google Play Services has taken up 37% with 14 hours of wakelock. Absolutely ridiculous.
No one has been able to figure out why.
I have an ATT D800 and just started experiencing this in the last few days. I already had disabled CIQ (checker says it exists but is disabled).
It may be the google play services issue and I just finished disabling those and charging to 100%. We shall see.
I took these things off, and got great batterylife after that:good: It should help for google play services battery drain..but report back if it works or not.
Settings -> Location access -> Off
Google Settings ->Location -> Location Reporting Off, Location History Off
All location settings are off. I've been with android since 2010. I've always kept location everything off.

I think there's an issue with WiFi on the D800. If I leave my setup the same as when on LTE, but turn on WiFi instead, I get a nice steady battery drain. I have compared BBS stats to when I'm on LTE and I don't see anything different. No wakelock keeping the phone on. Deep sleep is similar, etc.
Found the culprit. Battle Dragons, a game, was keeping the phone awake. Better battery stats showed it was never letting the phone sleep. Getting normal life now that I've uninstalled BD. No clue why it was waking it though, I stopped the app.

In the past week or so, I've noticed that my battery is draining unusually fast. I will take the phone to bed with me (I use it as an alarm clock) at 100% battery and I can wake up 7 hours later with it at 82%. When I look at my battery information, I see steady, solid drain over that time, with the biggest offender being Google Services. When I look in Wakelock Detector, I see the most usage (though seemingly not a ton) by Android System.
I found some tips on using Wakelock Terminator in Xposed to filter some things from Google Play Services from triggering wakelock, and I was optimistic, but it didn't seem to help.
Any advice?

Are you on a stock rom? Did you try greenify? It's on the play store. It kills the apps background services and the app itself until you start the app or the app is started by another app or service. Soon as the app os no longer needed it is turn back off. This program does not freeze apps it prevents them from running until needed.
Ah, sorry, I should have mentioned my rom and such. I'm running ForceROM, a relatively older version (maybe 2.3?), since I never felt the need to update.
I haven't tried Greenify. Haven't actually heard of that one before. I'll give it a shot. Thanks for the tip.

Try a custom kernel like KToonsez in addition to Greenify. It's amazing what you can end up doing with that kernel
Sent from my SCH-I545 using Tapatalk
ForceROM includes Ktoonsez kernel. For the last 8 months or so, I've had great battery life. This is a sudden and recent change, which I'm assuming to be caused by an update of some Google app (such as Play Services).
How do I use Greenify? Or do I just install it and it does magic?

Do you have auto-sync enabled? What Google Services do you have enabled for sync? I used to have a similar issue but turning off sync for things I don't use (like newsstand, etc) helped my battery life a lot.

I believe that installing Greenify might have done it. Battery usage looks much better today. I'll do a real test tonight when I get it charged to 100% before bed.
Well, I'll be...
I think that the problem is wifi. When I'm at home, I'm on wifi, and the battery is constantly draining. When I'm not at home, and on mobile data, the battery is well-behaved.
What's up with that?

Some apps can be setup to sync over WiFi only instead of 3G/4G data. but you have to check what apps would be the culprit. I know Google play, dropbox's picture upload feature can be set to download/upload/update over WiFi instead of data. But the only way to know is to see what apps connect over WiFi.
WiFi is suppose to give you better battery life since its signal is usually nearby and your phone doesn't have to use more power to find a better signal like it does with 3g/4g. I know for me it does since there are very few towers in the middle of the dessert.

So, interesting twist to this saga. Leaving wifi off takes away the solid blue bar on the battery screen, but I still see the same level of battery drain (about 18% overnight). Very intriguing.

Sounds like you're losing power to things syncing over wifi. Maybe try just giving it a week and watching it to see if it settles down. Google play sometimes settles down on its own. I also vote to check out greenify. With the donation package you can work wonders at calming down power hungry apps, even system apps.

My situation has suddenly taken a turn for the much worse. I don't know what's going on. I haven't added anything new or changed any settings since installing Greenify a while back. Now, the battery is just tanking. I got up to 100%, ran Battery Calibration and now, about 2.5 hours later, I'm at 82%. Could this just be a problem with the battery itself? Do I need to replace it?

Honestly there are a few days where the battery life suddenly drops dramatically. I've experienced this on unrooted mf9, mk2, and nae. Give it some time and see if battery life comes back up. You can reboot the phone to kill a rouge app that might be the cause.

This is the first I've heard the term MJA, so I don't think I'm on that.

Well, peers have told me:
1. Battery saving apps are pointless with how advance Android is nowadays. Also especially since Sony has already included enough battery saving software in their devices.
2. The battery saving app keeps running, so that itself drains the battery.
What do you think?

1 is correct
2 is partially correct, depends on which power saving app, I didn't notice any real drain from Battery Guru, though it didn't help increase it either.
I've never used Battery Guru before, but I think I'd rather purchase Tasker to do the job of location based Wi-Fi for my phone.
Would it drain battery or such if I have that act like juice defender/battery guru instead?

Ive used battery guru for a while, but looks like it doesnt do much. So i uninstall it already.
With the latest version of Stamina I can't really see what BatteryGuru can do to further improve things.
The Z3 effectively turns just about everything off in standby if you ask it to, firing up when you start using the phone. Battery Guru attempts to learn your usage, so it will still allow data at certain times and restrict completely at others.
I'm very happy with Stamina and uninstalled Battery Guru some time ago. I still have it on some other devices tough, especially anything that doesn't have any native power saving functions.
I do wonder how Sony is going to combine Stamina with the Lollipop battery saver, which is a simple on or off - along with the horrid orange bars. That's very much all or nothing with far less intelligence, so maybe Sony will not use that at all.
Hey friends!
Im not sure if im posting this into right thread, so if not, please move it to proper place.
Well, as topic name says, im looking for a way how to prolong my battery life. Im gone from home for most of a day, and im running out of battery at times i need my phone to be awake. Im currently using (my signature) and im looking for any advices for apps, tweaks, roms, mods and kernels made for battery life. Im not prone for some kind of smoothness (which ROM im using really is ), ill let that to more powerful smartphones; i need it for work. And i dont care which Android version or kernel version ill be using.
Thank you for any advices.

You said it mate. I just had to wipe my Nexus S that was running CM11 weekly because about 2 weeks ago I had massive battery drain. At first I thought my original battery from 2011 had packed in so I got a new one out of the draw but battery drain was massive again. I looked a Google Play Services and it was draining 75% of my battery while the phone was in standby. I tried narrowing it down to a certain app but gave up - I just couldn’t stop the battery drain. So I put the latest CM11 weekly on and so far its back to normal. But I have no idea why a stable phone since January suddenly had a problem with Google Play Services. It must have been an update or an app. Who knows.
I just hope it doesn't start again.
