Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

Juice Defender. The free version of the app, using the default profile, should take care of this.

Dear All,
My N5 draws excessive battery when in standby mode (screen off). It usually ranges from 300-400mA per hour. I was usually getting only 2-10 mA on my N4. I installed the same apps on my N5 that I used on my N4. I'm not a sure if Google Search is constantly on. I disabled Google Now, Google Play Books,Google Play Magazines, Google Play Music, Google Hangouts, Google Newsstand. I'm using Battery Monitor Widget by 3C and 2X Battery - Battery Saver. The Battery Monitor to keep track of the discharge amounts. I am still getting 3.5-4.0 SOT though. Any ideas for common excessive battery drain on Kit Kat 4.4 / N5?
Is the battery monitor not using battery to do its job?

Of course it is but not 300-400mA drain. I've used Battery Monitor Widget since N4 with no problems. I'm just not sure which app will draining the battery. at the aforementioned mA.
I used the returns feature to resolve the battery drain.
Returns feature?

What's wrong with the stock battery manager?
Do you have your WiFi or cellular data on for most of the time?
A live wallpaper?A app that's constantly on checking for any live updates perhaps?
Same apps as N4

My WiFi and cellular is automatically toggled to go on (screen on) or off (screen off) by the app 2X - Battery Saver. I used it on my N4 and I had no problems. I can't pinpoint which app is draining. Google Search is always 3rd on my list even when I don't use Google Now.

lol I think he meant that he returned the phone and got a replacement, or a different phone.
If you want to be very specific about what is causing your drain, then get BetterBatteryStats. If you're rooted, you will see under Alarms the specific service that is causing wakelocks. Most likely it is Google Play Services. The battery drain sucks. Turn off Location reporting in Google Settings (and also turn off remote location under Android Device Manager). Pretty sure that doing both is what helped me. But I went back because I am trying to see if Google Now is worth it. You should aim for 1% per hour idle drain and ~95% deep sleep

I'm not rooted but thinking about it. Google Play Services had been tamed. What I did miss was the Android Device Manager. I just disabled it and see what happens in a few minutes when phone is left idle. Location Reporting I knew about before so I turned it off when I just got my N5. I'm at 1% every 15 minute interval. I was at 1% for 4hrs. at idle when I was using the N4 but not anymore.
1% per 15 is still way too much. Post your BBS log here. Charge and unplug your phone. Leave your phone idle for a while. Then post the log here. You don't have to be root

I recently turned Google Now on and I think it's causing a huge battery drain - so I turned it off, rebooted, and my battery is still draining, hard. Used to be able to get at least 12-14 hours or longer and now it's hitting 10% after only about 8-9 hours.
Am I missing something to actually get Google Now to shut down completely? Or is there something else?

Hello, if you're rooted you can freeze the application or delete it.

Google Search. I don't necessarily want to delete/disable Google Now (and yes, I am rooted), actually kind of like it in some cases, but what I'm saying is that I turned it on, noticed a larger battery drain, turned it off, rebooted, and battery is still draining at same rate.
So what you're saying is it might not have anything to do with Google Now then. Maybe more so locations, but we'll never know until you dig a bit deeper and find out what's causing the drain.

What? I said it was google search that was killing my battery. The only change I made from standard stock was turning on Google Now. then I noticed much steeper battery drain. So I turned google now off, and am still seeing very steep battery drain.
Just turning it off saves alot of battery and I hope google fixes it soon.

Turn off location reporting and location history. Problem solved, and Google Now still works just fine.

I would suggest to turn off the "keep Wi-Fi on during sleep" as well as "Scanning always available"
I noticed a very big difference in battery :good:

Not just the reporting, as I had the same thoughts you did. Turn off history as well.
I haven't had an issue since then.

Keep Wi-Fi on during sleep is going to save you battery, unless you happen to do better with your data connection then your WiFi which would be contrary to most. Overnight I would typically lose 2-3x more battery on data then WiFi (3g/H) using that option.
Disabling scanning always available would account for your improved battery.
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Huawei Nexus 6P's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Same, last night went to bed at 32% and woke up with 30%. It's MUCH IMPROVED from previous versions of Android.
Having major issues with Doze, with battery drain of between 15-20% overnight.

Just wanted to show that some users aren't experiencing the same battery life "Doze" is supposed to provide.
Have you turned off Wifi always scanning?
From full charge at 9pm i loose 3% when alarm goes off at 5:30 am
I've lost anywhere between 1%-5% overnight with doze. Not really sure why the difference either. When I look at the battery chart, it's showing very minimal "awakes" each night. Either way, this is much better than prior version of Android where I'd easily lose 7%-10% overnight.
One of my only gripes with doze is that it kills some helpful apps that haven't been updated yet. Timely, I'm talking about you... No more smart rise until there's an update.
I don't know exact numbers (haven't been checking that hardcore) but the battery graph looks damn near flat while my phone and I are "dozing."
Deep Sleep Battery Saver is a really great app to help reduce battery drain. I was struggling with my phone always being awake, even with aggressive doze mode and DSDS helped a lot.
It does require root because you need to make it a system app, though.

I'm getting a 5% drain in 2hrs dozing and apparent exchange services is the culprit any ideas? It survived a factory reset, cache wipe etc..

My guess is that the exchange services are treated as priority (just as with SMS and phone calls) and keep the phone from going into doze mode/continually waking it up.
I'd suggest using a third-party app for Exchange (such as Outlook or Cloudmagic, which is excellent) and remove the other exchange account. Doze will put those apps into hibernation unless you whitelist them in battery optimization. Give that a shot and see if the issue persists. I'm using Outlook and haven't had any frequent wake-up issues. My phone dozes like a baby.
I am curious what others are seeing in terms of deep sleep percentage and as a direct consequence battery drain? I have no 3rd party apps installed yet on my phone and have Google set to sync only Inbox, Pics, Chrome, Contacts, and Calendar. I also have most of my apps set to close with screen off. I only keep Inbox, Hangouts, and Nova Launcher running. With these settings I get a deep sleep % of about 85%. Whats really perplexing the awake time (with screen off) is over 3 hours over a 48 hour period which results in about 1.5% battery drain per hour. I know from previous experience with Android that this is mainly due to power wakelock which is essentially apps syncing. However, with all my other phones I usually get about 95-97% deep sleep at idle and a battery drain of about 0.3-0.5% per hour.
So my question...what are you getting in terms of deep sleep percentage at idle and battery drain rate per hour?
i noticed the same on my mate 9 after latest firmware update after few days but havent figure out what is causing it yet

This is overnight time so there is no wifi and network data. I have root and debloat all huawei apps. Currently there are about 100 apps on my phone and there is no app managing battery except the stock huawei one. You can go back a few pages to see what I use in my normal days. Currently I start to play a new game with my friend, it's called Valkyrie Connect and with this phone I can handle it for about 6-7hrs of playing game at 40% brightness with 15% battery left. Let it settle for a few day then see if it helps.
