I turn my phone off last night with 50% battery left. This morning I turn the phone on and it tells me to charge the battery and then shuts off.
Here is where it gets weird; the exact same thing happened to my wife's phone except she had almost a full charge before turning it off.
What is going on?
I don't know I have gone 26 hours in mostly standby and I still have about 65-70 % of battery left. Check all your settings. I only have sync and back light to Auto turned on.
This is not normal and has never happened to me. Have you installed any apps from the market?
Little more info, please. Are your phones pre-OTA or have they been updated? Are they rooted? Did you just buy the phones? Have you trained the battery (fully charged then fully drained)? Have you done a factory reset?
Both phones are post update. Both were turned off by holding the power button then selecting "power off". Both have exactly the same apps that we had on our previous Androids (Vibrant and N1). Both bone stock. Have not factory reset, really don't want to go through the work of setup again.
I have never powered mine down completely overnight so I guess mine is not the same comparison. I might try it though just to see.
Ya they hold a great charge all day when on nut lost all their charge when powered off.
Is fastboot checked in settings or not?

Is this a feature known to eat up battery? I mean if I left the phone on all night it would have still had a charge.

Idk, shooting in the dark here, never heard of a problem like what you have. Wouldn't hurt to try. I know the fastboot has something to do with the way the phone shuts down.
That battery behavior is just strange unless you have apps syncing frequently.
I unplugged last night at 1am, went to bed, and got up this morning at 8am, it went from down fully charged to 93%. I have autobrightness on, wifi on, gmail and exchange syncing, every other app that syncs I have it to sync at least every 6 hrs or once a day.
I've had this phone for 3 days now, and I'm consistently able to get 12-14 hrs of battery time, and that includes heavy internet use, radio, tv, etc.
Are you in an area where it's constantly trying to pull a signal? Maybe that's what's eating the battery?
Are you doing the steps to condition the battery? Charge until fully charged, turn it off and keep it charged another hour, then take it off charge and use it until it completely dies on its own, charge it back up again and then use as normal?
Yeah, but he saying he powered the phone down, not left it on and just idle. Now that's strange

Yes but he is powering completely down not just in standby mode so nothing would be syncing. I will try this tonight and see if I have the same thing.
My wife had about 75% charge, I had about 50% charge. We both held the power button until the menu came up, we hit "power off". Both of our phones had dead batteries this morning.
I would download spare parts and see what apps are using ur battery

None of this would matter cause the phones are powered off.
If you have fastboot checked, the phone is not actually turning off. It goes into a quasi-sleep state and some low level processes may be running. That said, your problem may be related to the following thread:
forum.xda-developers.com/showthread.php?t=839935
the fix: enable USB debugging mode.
Another possibility, and this is someting that's happened to me in the past: the phones may be plugged into an outlet that loses power when you turn off the lights at night
Fast boot is similar to a Windows computer going into hibernation or standby mode.
Mine has been acting weird since Friday. I woke up and it totally discharged overnight... it was 100% charged when I went to bed. Yesterday it was laggy constantly and the battery has been draining at least twice as fast. Today phone locks up constantly.. apps are force closing.
... have rebooted, pulled the battery, etc... phone has gone from a dream to a nightmare in that respect.
Gonna double check my debug settings and see what happens.
EDIT: debug was turned off. I turned it on... will report back if there is a change.
UPDATE: Turning on USB debugging and a reboot seems to have fixed it. Battery drain `back to normal.
Is it normal for my alarm to NOT go off when the phone is turned off but rings as normal when it's on?
I ask this because I sleep at night with my phone turned off. The alarm is set for 6:35 as normal for the morning.
For the past 2 days it failed to go off. The phone was however switched off, I take it the alarm does not ring unless the phone is on?
Should this be true it is strange as the older phones, the ancient Nokia's and Ericsson's used to ring while the phone was off.
My previous HTC Desire HD had the same issue, the alarm would ONLY ring when the phone was on.
Should it be turned off it would not go off.
Why is this? Any way to fix it?
Anyone?
Simple enough,just put your phone to flight mode and turn off the screen,dont power it off and dont mute it.
cuz automatically waking up is not supported by wm/android device.

Excellent idea, flight mode! This way will get undisturbed plus no more than 1 or 2% loss of battery in standby mode...
Also no one can call & disturb me. I though auto wake up wasn't supported, just wansn't 100% sure.
Cheers valest.
Valest, this morning at 6:35 my alarm rang for the FIRST time!!!
You are right about not turning the phone off...
I forgot to put in on airplane mode but thank god it didn't go off and I hardly lost any power...
Over a 7-8 hour period battery dropped from 100% to 98%
What excellent battery the Streak has... Screen brightness is ALWAYS set to 80% too.
I'm half way through the day and battery is still 94%
Lol your battery must be special or you really don't use your phone much. The battery is certainly better than most but not that great.

PS welcome to the streak. Even though its a year old its pretty good

becuz he was sleeping and the phone isn't really in use*^o^*
cpu and screen backlight are battery draining,so turn off your screen and let cpu go idle(set itself to 245mhz) helps a lot.
still,it could be crazier,my streak survived a 3 hours trip with less than 10% battery: turn down brightness,go to flight mode,shutdown unnecessary background app,set cpu to 245mhz.I was reading an e-book back then.

Yeah that's one thing I miss about Symbian. I could set the alarm on my Nokia then shut it off.
I currently use Tasker with a "night saver" profile I created. From 10pm to 6am:
Shuts down cellular data
Shuts down wifi
Shuts down bluetooth
Shuts down GPS
Turns off auto-sync
Drops the volume to "1"
As an alternative: you could buy a dock (i use the slacker dock) and plug it in on your nightstand.
It charges so you dont have to turn anything off and it's upright so it even looks like a clock

Haha, clever idea! But after testing it & only loosing 2% battery it doesn't bother me keeping it on.
I thought it would have taken more power as my old HTC Desire HD had a crappy battery and needed to be charged almost every day with LITTLE use...
Standby overnight would take around 8-10% This is based on a 6-7 hour period, which I think is bad as it's doing nothing...
This is my first tablet and not sure about battery life and everything. So I left my tablet on through the night and lost roughly 10% through the night. Not sure if thats normal or not. But if so, I will definitely be turning it off throughout the night or when I won't be using for awhile. But is there a standby mode or something we can put the tablet into?

I don't turn it off, no. One thing that will save you battery is to turn the airplane mode on when you're not using it.
I just turn off wireless and pwer off screen.
never been off
I never turn my tab off. At night.it will loose. 6 to 8 percent. At night maybe a bit more or less depending on how long its off.
And I use it often thru out the day
Awesome battery life
Haven't turned it off yet. I use it all day and plug it in at night around 20-30%, wake up charged and do it again.
I just turn the screen off overnight while charging; I leave wifi on to synch work emails & calendars. Nearly a decade of smartphone use has gotten me in the dedicated habit of charging everything every night.
Thing to keep in mind, tablets arent Kindles with week+ battery life; keep in the habit of charging it whenever convenient & you won't run out of juice unexpectedly.
I'm in the minority here.
I turn my Tab and Evo off every night, the phone just before bed. It save a bit of batt life and unwanted calls in the middle of the night or any alert tones as I'm a pretty light sleeper. I've also been doing this for probably 7-8 yrs with all my smart phones (Symbian, Win-Mo, Palm, BB and now Android).
Sometimes I turn it off at night, sometimes I just leave it on. It's definitely on ALL day. I haven't really seen it losing much battery if I leave it on overnight, but I don't have it configured to sync frequently. Whenever I notice the battery is getting a little low, I charge it up again -- don't really have a set pattern or routine that I charge it.
Anytime I know I won't be using it for twenty minutes or more, I just shut it down.
Not sure there is a right/wrong, good/bad way to do this, as it's pretty much a personal preference thang!
If I'm not gonna use it for more than a day, sure.
I also turn on airplane mode when I'm reading via Kindle or anything else that doesn't require wifi.
On a semi related note, does anyone else find the screen is too bright if you're in a dark room reading, even if you have brightness on the lowest setting?
So far I never see any difference to turn AIRPLANE MODE on... but anyway some people believe so... let say that work... hu hu hu
well
to answer I never turn off my tablet, neither turn off the wifi
I try to not use AUTO brightness, set brightness to medium.
I will turn it off... well... actually I do not.
to muqali. on lowest setting? on dark room lowest setting I think it's fine (but I have an antiglare screen... that dim the light)

That is crazy talk! I'd suffer some serrrrrious withdrawal
On to the question, no, my tablet stays on 24/7. The closest it gets to off is booting into recovery, but then it's right back on.
All my backups, security scans and cloud syncs are scheduled for the wee hours of the morning so wifi stays on at night too. Also, my iconia is my alarm clock, which is very useful for a shift worker who needs different alarms on different days.
only if the battery is low and Im to lazy to go charge it
I only turn my tablet off in order to reboot when it freezes up or gets laggy (maybe once a week). The rest of the time, it's on standby or being used.
I leave it on sometimes, other times I will randomly turn it off. I mean, its not a phone.. no reason it should be on 24/7. I don't even leave my PC on 24/7 - as it saves a lot of electricity to turn it off.
My phone (Droid X) however, stays on 24/7 =P
Yeah, I've been leaving mine on and its been just fine. I notice it turns off wifi or I guess at least disconnects when the screen is off so I'm sure that helps. At nights I guess I can turn airplane mode on and that should help. I'm impressed though with the battery so far.
I always turn it off when done, unless I know I will be using again in a short.

I use the Nook app as my eBook reader instead of the Kindle app. The Nook app has a separate brightness control within the app, and it allows me to turn even the white page brightness down to where it's very comfortable to read even in a pitch dark room. The nice thing about this is when I'm done reading and exit the Nook app, the global brightness settings for the tablet are restored so my dark wood wallpaper isn't too dark.
I'm not sure if the Kindle app has its own brightness control or not, but it might be with looking into.

yes, I noticed too, it's too damn bright, but not as bright as my phone, on the good side screen comparison between iconia, transformer, zoom and ipad2 the iconia gets praise cuz it's super dark black... you can notice easily (like me) if you're in the dark and look the status bar
I do not. I don't really ever turn mine off actually, except if the battery is at low and I'm out and not able to charge it, but that rarely happens.
I don't turn my PC off either. Turns out it doesn't save as much energy for me vs. time. I'd save roughly $90 a year if I diligently turned my PC and HTPC off...my PC however serves as the file server for everything in my home and I'm also very random in terms of bed times so it would cost me so much time (and maybe some parts issues as well) turning it on and off every time I needed to use it.
Hi all,
I have updated to new FW 8.6.5.21 yesterday. After update, I still saw that can go to deep sleep mode. But after full charge, old problem still happend, never go to deep sleep mode again.
I have no dock.
Does anyone know how to fix????
There was a post about this earlier. Here you go.
blessedswine said:
For those of you that have a transformer that wont deep sleep whether its on or off the dock, doesnt matter you can get a app for that. its called Auto Airplane Mode, and it puts your transformer in airplane mode each and every time you turn the screen off, i have noticed a huge difference in battery life after installing this app. using Cpuspy my transformer went into deep sleep for 10 mins max a night for the last week. installed Auto Airplane Mode and the transformer goes into deep sleep within a min of turning screen off now. I already had the wifi set to turn off when screen is off and everything, the only thing i did was add this app.

Airplane mode wasn't the answer before and isn't the answer now. I haven't charged my transformer since the update so don't know if it is happening to mine but if it is the same as before then it isn't radios that is causing the problem its a bug in the OS that never lets it go into deep sleep after charging. A reboot after charging usually sorted it until the next charge. That is so long as you don't have a dock because the tab thinks it is being charged when on the dock. I hope they haven't introduced this bug again because it was a real PITA when it had it before.

I also installed Auto Airplane app, but I think it is not the solutions, still no deep sleep. Because I have no dock, after charging, I reboot but still no deep sleep. Now I have to charge everyday
Mine is fine. Deep sleep verified with cpu spy.

Mine keeps disabling the setting : turn wifi off when screen turns off.
This update is ****ed up!
mine goes into deep sleep perfectly now since the update, it wouldnt before unless I used the auto airplane app. Battery life is much better now.
mine wasn't sleeping, till i did a factory reset. now its sleeping as it should.
I am having the same problem since the update. CPU Spy indicates that it is in Deep Sleep, but I am having constant battery drain in AND out of the dock. Battery says that wifi is doing the damage. I have it clicked to sleep when screen timesout. Auto Airplane Mode worked. I am not happy though. I should not have to use it.
Mine doesn't sleeping whether install Auto Airplane mode or not. I'll try to factory reset....
Happy to say mine is still OK after the update. It till goes into deep sleep as it should.

I tried fatory reset, but nothing change. Still not sleep...
How come my transformer instead of going into a completely dormant sleep mode it goes into a sleep mode where every one minute according to the clock it flashes on the screen for a few seconds just to show the time on the lock screen???

Damn, this looks like the problem I'm having: when I check what's draining the battery, the first place with 58% is Screen! I didn't see the screen flash, though.
Upd. Yes! This is exactly the issue I'm having! I checked - the screen turns on from time to time, not every minute, but still... so no deep sleep for me here

Need to check permissions on your apps as they change with updates. some apps keep the TF from sleeping others wake it up periodically to check for mail or other syncs. Need to check them all as some things you might never expect like free games keep it alive.
I'm really stuck with this problem. After full reset and only one app installed (Dual Battery Widget) Transformer spends some time in deep sleep, then suddenly wakes up. You can see it on the attached screenshot. I have no idea what happened around 3 am when the device woke up and never went to deep sleep after that.

I think mine have the same problem. Sometime it go to sleep mode, but I don't know when. Event after reboot, no application running, still not sleep....
I had this problem with mine, it turned out to be some of the apps kept waking it, and then it wouldn't go back into deep sleep. I uninstalled some of them and haven't looked back since. Specifically Facebook was a big problem, even with no syncing.

The only app installed is Dual Battery Widget (I did a factory reset). Could it be the reason?
Maybe with this you can see more.
I like having my LED notification light on as much as the next guy, but I think it's preventing the phone from going into deep sleep, and while it may be running one core at a low clock speed, it still is using a enough voltage to drain the battery rather quickly. If you look at your battery usage and the phone says "Awake", that means that the CPU was doing something at the time and I've noticed it's always awake whenever I have a notification.
Is there a way to let the phone sleep and have LED turned on, or is it just a design flaw in Android?

If that is actually happening, it's a bug - but not one in android. On both the international sgs3 and the gnex, the phone turns on the notification LED (or turns it on in a "flash" mode) and goes back into deep sleep.
The processor should NOT be needed for handling that LED once its started - it should run on it's own.
