Tablet doesn't go into deep sleep - Xperia Tablet Z Q&A, Help & Troubleshooting

So I basically unplugged my tablet last night after it was fully charged and let it sit overnight.
Checked it this morning, and under then normal battery graph it showed it was awake pretty much the whole time.
Using BettterBatteryStatus I see 0 Deep Sleep, 10h34m of "Awake"
Checked Kernel Wakelocks, I have "suspend_backoff" at 5h28m and "alarm_rtc" at 4h10m.
Partial Wakelocks only show "bwl" (Beautiful Widgets) at 8m9s. That's the highest Partial Wakelock.
It appears to only have dropped 5% all night. Although I'm not sure I believe that either, this tablet seems to stay at 100% for quite a bit, but once it starts dropping it starts dropping faster... I can use it for 30 minutes and still be at 100%, then another 30 minutes and have it drop from 100% to 92%.
I've only had the tablet 3 days so far. So far I like it, I'm just trying to figure out why it won't go into deep sleep. Better Battery Stats isn't giving me any idea, and usually it's pretty good at telling you what is keeping the tablet awake.
And no I have not rooted the tablet yet.

don´t use apps that are running in background. look in wakelocks tab of better battery stats (kernel and partial) and lookup whats waking it.

That's... what I did. See my first message.
That's the whole reason I use BBS.

Wifi is on all the time, maybe you should try to turn it off while screen is ff in wifi setting or use Better Wifi On Off.
You don't use Stamina Mode ?

Yeah, I'm playing with this tablet a bit more and realized if I have to use stamina mode to get it to go into deep sleep. Most other android devices I have and have used will go into deep sleep even without any sort of 'stamina' mode and even with Wifi set to always be on. Looks like Sony has made quite a few changes to the way the power settings work with this tablet and the kernel.
Even without stamina mode I get pretty good battery life. With stamina mode it's better. With stamina mode (and very light usage, screen on time is only 42 minutes) I'm at 1 day 8 hours and 84%.

Also I remember one of the sony dev said on their forum that there was a bug (on previous rom) that report wrong battery drain, sorry too lazy to search for the link.
Youn can use geolocalisation to manage wifi too, when near a registered access point it turn on/ and off when going away.
Can't wait to get mine in a week!

My deep sleep is back after I've found that some Sony's b2bcustomerinstall was sending alarms like crazy. Disabling it reclaimed the battery with a notable difference.

RILJ wakelock, but CPUSpy still shows 99% deep sleep?

I honestly don't understand this. A few days ago the RILJ wakelock started showing up on BBS. It seems to keep going up - right now after 16h on battery it's at 16 minutes and the count is nearly 500. It's at the top of the partial wakelock list. The part that got me confused is CPUSpy - from what it shows, my phone deep sleeps perfectly. If I clear stats then lock my phone for, say, one hour, when I turn it back on it'll show 99% of the time spent sleeping and only a few seconds spent at higher frequencies.
How is it possible that I have a pretty frequent wakelock and still be able to deep sleep almost all the time? My battery drain isn't too bad, in fact I think a 3% loss over night (7-8 hours) is brilliant. After using wifi, it'd drain a bit faster, but settles after a while.
And I don't have my phone with me right now so I can't post dumps or screenshots or anything, sorry about that.
Edit: I'm on CM9 RC2, Siyah v3.5 if it happens to matter. I updated to Siyah 3.5 yesterday.
Why did you post this? If your battery is fine and you have no problems then everything is fine, no need for posting right?

Better ask in BBS thread. Maybe a bug, if your battery usage is going fine then I think CPU Spy has no problems .
I don;t think this is really a problem.

Battery Drain EXTREMEMLY Fast

Hey guys, I am having a problem with my Amaze, more specifically, the battery is dying absolutely WAY to quickly. For example, yesterday morning, after unplugging my fully charged phone, I dropped it straight into my pocket, and maybe looked at it twice the entire day. When I pull it it at the end of the day, the battery is red, with 8% left. If I were to be using it, the battery would last about 30 minutes on a full charge, most likely. I've also noticed that the phone is really hot, even in my pocket. If it helps, I am on ICS and have been using it since it was leaked in April, however, this problem is new (about 2 days ago is when it first started), as I usually get about 8-10 hours with moderate usage. Can you guys please help me? Thanks!
Well if it just started happening recently, and you haven't made any changes, then the battery may just be going bad... If that's the case, you can call HTC and they will send you one free replacement.

could be just the battery.. but if you don't mind me asking - how long have you owned the device? I suggest you dl JuiceDefender from the playstore and see if that helps - Definitely helps my device get through the day with moderate use and one time charge every 1 1/4 a day but this could vary on owners usage. Also, check your settings to conserve battery life such as turning off wifi, gps, auto syncs on your fb, gmail etc. and adjust your brightness to the lowest if possible and OH... less widgets and windows > less power that the battery consumes. Hope that helps!

Like I said, this just started happening. I didn't just decide to leave all my wifi and GPS and Bluetooth on all day. Also, to answer your question, I've had it since the beginning of the year. I think it's just the battery. I'll call HTC and report back.

Nope, battery life isn't that great with this phone, depending on how much you use your phone and what all you use it for you will get any where from 6-14 hrs + or - some. Also your Rom and kernel will make a difference..

Nice!... Glad to hear
This happens to me from time to time, and the phone is ALWAYS hot when this happens.
What I've come to discover that it's usually something that' activating the phone while asleep.
The phone is hot, because the processor is being used. That's why the battery is completely dead so quickly, something is pulling it out of deep sleep and causing it to run full bore. The key sign is the phone is hot.
I recommend you get an app that lets you see wakelocks, and what's keeping the phone awake etc (I use GSAM battery monitor) Whenever I notice my phone becoming hot for no apparent reason, I know for a FACT that my battery will be dead in a matter of hours. Lately it has been "Android System" that's the culprit, and I can't quite nail down what is doing it, but it's very random and not much of a problem because I do a reboot and things are back to normal.
First, try to reboot your phone. Get system tuner and see what processes are using the processor when the phone is hot (make sure you show ALL processes, even the default excluded ones). Check the wakelocks. Get battery monitor and check the mA usage (it keeps a running history). When my phone is running optimally, I have a mA drain of around 70-90mA when screen off/deep sleep, and it should maintain this type of drain... when my phone is becoming hot for no reason, I see numbers anywhere from 300-600mA drain for no apparent reason. A lot of the time there was an APP that was offending, so I would first check that. Like I said though lately it has been "Android System" and it's kind of hard to nail that down, but it's so random.
When my phone is cool to the touch most of the time, I know it's running optimally because it's achieving deep sleep. I've found a lot of it has to do with what you had running before you turn the screen off. A reboot ALWAYS fixes it for me. If you can't seem to nail down the offending app, do a full reset back to stock and you should notice that your phone runs very very cool when the screen is off and it's sleeping. I usually get anywhere from 24hrs-2 days of moderate use with the screen off governor set to conservative, and maximum clock for screen off ~600mHZ. I use interactive governor for screen on, but that's for responsiveness and you'll probably have better luck with ondemand for battery life. YOu can set these in System Tuner.
Just remember, if the phone is HOT, it's using energy. If it's hot, something, somewhere, is causing the processor to run at a high clock frequency. If the phone is HOT after being in your pocket/screen off for a good amount of time, something is definitely wrong/rogue app. The phone should never be hot returning from deep sleep. I bet if you check your default battery monitor (The android one) you'll notice that the bar for AWAKE is probably almost solid blue, something is preventing it from going into deep sleep. If I notice my phone is hot when I take it out of my pocket, I immediately know that something isn't right. This should NOT happen.

I'm just past my 9th day of using my Amaze 4G.... so far, if I turn off data and turn off autosync, my drain per hour goes below 1%/hour... so i could get >50 hour idle battery life + 4 hours screen usage
with data on and autosync off, maybe 2%/hour -> this translates to ~ 20hour idle battery life + 4 hour screen usage
with data on and autosync on, maybe 4%/hour -> 10 hour idle battery + 4 hour screen usage
I have only calendar widget on my home page, only Google Accounts on auto-sync (2 mail account, 1 contact, 1 calendar)....

what program do you use to measure battery drain? I use Battery Monitor Widget, but it's not giving me an accurate answer (lets say I had the phone on idle w/o data/sync... the available % is stable over 5 hours (~1% loss per hour), but the current usage says at least -100mAh)
for me, the idle battery drain (apps autosyncing/using data) is the problem
I see my device properly going to sleep (deep sleep is the majority of the usage, not too many wakelocks/processes.....)
with data off and sync off, idle battery usage goes to a minimum

I use battery monitor widget to measure drain.. as far as accuracy, I'm not sure? I don't know if it's EXACT but it seems to be a pretty good indicator of drain. When in deep sleep the phone usually measures anywhere from 70~mA-120mA. Usually it stays below 100. Before I changed the screen off governor / max freq (screen off) it was almost always 100+. Screen off governor is conservative with a max freq of ~600MHz.
I have no idea how exact it is, but when it's reporting ~300mA, my battery is definitely draining much faster.. and when it's reporting 500-900mA~ my battery is draining incredibly fast, so it at least seems to be a solid indicator of current usage.

On my previous phone (LG Optimus T / Optimus One/ P509, CM9 ICS ROM), Battery Monitor Widget reports more accurate readings (idle with data off= -2mA or -20mA<dont remember>, accurately representing that 1% of battery would last at least 2 hours)
Phone with the new kernel (KozmiK Ruby -0.5a) still goes battery drain crazy (even with Juice Defender installed now).... I hit 10%, then got fed up, turned off data... then the phone slowly sipped battery for the next 3 hours going down only 1%.... sigh
I think Facebook Messenger is the data hogger in my case, since I do use it often... will try a new ROM build without logging onto facebook messenger, see how it goes

What you said is true, at least for data on - autosync on. My battery last around 10 hours idle + 3.5 - 4 hours on screen usage. It seems that autosync eats a lot of battery. Will try to turn that monster off and see how much it will improve. I have bad habit to push refresh button on gmail/facebook widget, even with autosync on,
I used to get 14-16 hours. Now my battery won't last more than 6 hours. I gotta replace my Anker

Most recently I got 1 day and five hours with a fair amount of use by using faux 011 kernel and using CPU editor script to set it to battery saving profile. I'm at 45% right now with fairly heavy use after over 18 hours.
Battery life is totally under your control, it takes some work to get it where you want it.. but you also have the option of buying a bigger anker battery with external charger for $20 and carrying that spare battery, and simply not giving a damn.
Just saying, battery doesn't have to matter for a very small price and a little space to carry the spare battery in your pocket.

Phone not Sleeping

I'm having this issue of my phone not sleeping when the phone is off. I checked kernel wakelocks and the number 1 culprit is Power Manager Service. Anybody have any idea what this is. A distant second is wlan_rx_wake but I'm not too worried about this.
The devs are working on it. If you aren't on the latest CM9 build then you should update.

I'm actually not on AOSP stuff. I'm on one of Neo's roms.
Edit: I just ran a test and for 34 minutes the phone slept for 33 of them. Even though the phone lost 4 percent of battery in that time. I see people saying they have crazy good battery drain rates (like .25%/hr). I thought i would get better life but I guess thats just the way it is.

that rate is based on usage. keeping apps from starting. keeping apps running in foreground all the time. lots of frozen unnecessary apps. screen brightness between 10-20%. betterbatterystats monitors wakelocks

When saying .25% per hour I was talking about during sleep but I get 3-4% during sleep. I am going to try and wipe everything and start from scratch. But if my phone is sleeping >90% of the time when the screen is off, there's not much I can do to improve battery drain during sleep no(app wise), and screen brightness won't help at this level cause it's when the screen is off?
have to watch for partial wakelocks or any wakelocks. apps automatically starting when not needed or still running will reduce your amount of deep sleep. use betterbatterystats to monitor usage while it's off

[Q] Too Many Wakelocks...

I just got my G3 yesterday but the battery drains so quickly. I rooted and added BBS and there are so many sensors and such kept awake. In just wanted to see if anyone has a clue,what I should do to contain these.

Kernel wakelocks don't keep the device awake per se. Those are processes that run when the screen is on. That's why the duration of all of them is almost the same. There's not going to be much you can do about those until/if custom kernels come along. You can try a factory reset, though I don't think it will help.
You should focus on partial wakelocks since those keep the CPU on when the screen is off.

This list for kernel wakelocks goes on for a while. The partial wakelocks are minimal, but whatever is causing these kernel wakelocks is whats causing the device to get warm, and subsequently draining the battery at an accelerated rate (roughly 7%+ per hour with minimal usage.)
I have never before seen such an extensive list from BBS on any of my other devices. Usually its the accumulator of all the partial wakelocks at the top of the list of kernel wakelocks by a large margin.

I'm with you. Been searching around for things I can freeze/hibernate to minimize wakelocks. Like stated earlier though we really need a custom kernel to get rid of a lot of those Kernel ones. The Partials aren't really that bad.
I have only had this phone since earlier today though so I'm keeping my eye on BBS like you are

This phone does seemto have a ridiculous abou amount of activity going on. I had the dreaded (nlpcollectorwakelock) battery drain my first day but a reset took care of it. My battery had since calmed down and I'm getting good sot now. My android os stays at around 14-20%as well but a long as my sot is decent I'm not stressing anymore

Yea mine is only draining at around 3% am hour with my use according to BBS.
That's just on WiFi and doing some browsing + Tapatalk+ a little YouTube.... So I can't complain.
It'll take a few charge cycles plus keeping an eye what else I can freeze and hibernate.
Considering the display on this thing that's pretty good I'm happy.... Be a little happier with a SaberMod ROM and Kernel though [emoji2]

My battery life is just as good as on my G2. Under normal (moderate/moderate-heavy) use I can get a day out of it easily. Yesterday I went to bed with about 44% left after over 13 hours use (with 2.75 hours of screen-on time).
I would recommend using CPU Spy to make sure the phone is going into Deep Sleep. There might be some process keeping it at a higher functioning state and not allowing the phone to hit Deep Sleep. For the most part, the phone should be in Deep Sleep longer than any other processor state.
I think a factory reset is in order. If that does not help you might just have a bad device, or a bad battery.

My phone is showing a huge number of sensors wakelocking the phone, and it was only in deep sleep 17% of the time since I unplugged it 6 hours ago. That kernel wakelock for the sensors needs to be fixed and then our battery life will be stupid good. You can't get as much screen on time on the G3 as I do on my G2. I was getting up to 10 hours of screen on time on my G2 the best i've managed was 3.5 on the G3. However, custom kernels will probably help there.

I was getting up to 10 hours of screen on time on my G2 the best i've managed was 3.5 on the G3. However, custom kernels will probably help there.

The Sensor WakeLocks are quite ridiculous indeed, but what is your phone showing for Partial WakeLocks and Alarms in Better Battery Stats???
Only way I could get mine under control was to use App Ops to limit Google Play Services to NOT keep my phone Awake.
Then I located COM.LGE.IMS and disabled its Receivers then froze it.
Then I Greenify everything possible lol
That Com.LGE.ims thing was waking my phone like crazy, maybe 50-100 times an hour if I remember correctly and I don't even use the feature its tied into... WiFi Calling

I left the AOD on while I was asleep to test it out and it drained 30% of the battery

I'm not exactly sure what is causing it to drain like this. I'm assuming it's not supposed to be this bad otherwise nobody would be using it.
Strange. ..
No bother here, AOD I have no use for especially with extra battery drain.
It can't be the AOD. I've been playing around with this since your post yesterday. I've been unplugged since before 6am and it is now after 1pm here. Battery usage is saying I've been unplugged for over 7.5 hours. In that time, I've used 15% with 7% in the last three hours. Since then, I've had AOD on, watched a few youtube videos, listened to music from the SD card for about an hour, checked email and texts, checked G+ a couple of times, and scrolled through Instagram. Phone idle is reading 4% usage, Android OD is 2%, Google Services 2%, Screen 2%, Music 1%, Android System 1%, Youtube 1%. Which leaves a few mystery processes that didn't register enough to warrant a 1%.
Hi,
Make sure in aod settings that brighter display is not enabled. I agree with the previous post that since having the phone for a week and a half that aod is very minimal on battery usage. Personally I think it is a great feature since there is no led to show missed text or emails. I just glance at the screen to see if I missed any without having to unlock the phone.
Thanks,
Bryan
AOD might take 10% over 8 hrs at most. You def got something else happening.

I'm not sure what's eating it up then. I have wifi enabled but I don't think that should cause so much discharge.
Can you try the test again tonight in airplane mode? That will give a more accurate result.

Maybe try to turn off anything that syncs and test again? Im thinking Google auto syncs and the like.
phone idle 39% then second is android OS at 31%
39%? You definitely need to look into what else is running because I can tell you it isn't AOD. I get about 1%-ish per hour for phone idle.

Do you recommend something? Nothing tells me in detail to what is causing the discharge. My phone is not rooted and I don't really plan on doing it. Now it's saying idle 55% and Android OS 41%
No idea what to tell you to look at. I just know that I'm running AOD my phone sips 1% of battery over an hour's time if I leave it alone. There's something else going on with your phone when it idles.
Personally, I'd do a master reset ... if it continues - and not associated with an app - trade that sucker in for a new one.
Okay so this may sound odd and I can't officially say it's related but I disabled google's location history on my old phone and so far there's a noticeable difference. I will test it at night when I go to sleep. Usually by the morning 30% of the batter is drained.
Did you try to disable all google syncing?
This is really weird. I just checked my phone and I've had it off of a charger for the past 9 hours. I'm only down 10% battery and only 3% phone idle battery usage. I checked my google location history and that's turned on as expected.

So I left it the same way I normally would over night and this time it drained 9% instead of the usual 30%. Although the usage still says 41% on idle. I don' t know what's going on. I may have to do a factory reset as suggested by someone else
I noticed something weird. If you've got sync on for all of Google services but have each app (Like Drive, Etc) setup to update on Wi-Fi only, it might keep it attempting to sync forever. I went into each individual app and changed to update over Wi-Fi and data. Then the sync completed. Not sure if this is relevant but I thought it worth looking into if you've got sync on.
