[Q] 100% full charge to 0% in 6 hours??

I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?

Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

unrooted.
I have to leave for work now with out a phone, I will try to check up via computer (feeling like a dinosaur).

Ha ha I know I feel so bad when I don't have my phone. Maybe see if it happens again tonight. If it does I would get on to the carrier. Have a good day at work!

Ill try both.

It has been documented the Verizon has battery issues but not sure if they were meant to be fixed in the 4.0.2 update

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery

If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck 

My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings

how do you disable drm? and what exactly is it?

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.
Good luck.
BTW, both actions can be reversed.

[Q] No 3g during night hours, sleep mode?

Dear all,
Is anyone else experiencing the following problem?
When the phone goes to sleep mode during the night hours it wont receive any messages for whatsapp etc. It seems that it turns off the 3g connection when you turn the screen off during the night hours.
Does anyone know a possible fix for this?
I have gone through all the settings and could not find anything about this.
Cheers.

I recently got this on my Desire Z too, and I have not changed any settings on that. Then I noticed it's happening on my One X too..

no 3g late night
Hi there, i have a motorola photon. in the settings menu you can go to what is called battery and data manager. then tap on battery mode. it's default is set to nighttime saver, which will kill your syncing after 15 minutes of inactivity in the hours between 10pm and 5am. i set mine to performance mode. this will sync all of the time and i don't really care if it takes up battery since i am awake and ready to pop in a new battery off my kick a$$ battery dock wall charger!! hope this helps....

I think it's got something to do with what HTC said about "the phone learning" when you check things like mails ect.. so after it has learned that you do not check mail (for instance) during the night it disengages activies... or not

@mykeyvee, there are no such options in the stock rom on this phone.
Anyone have any other ideas?, i want everything to be synced 24 hours a day.

I don't think it's anything to do with settings. My Desire Z is on 2.3.7 and only recently have I got this bug.
My One X is stock unrooted. No settings for power saving.

Accounts and sync>sync schedule>smart sync
Is this what is effecting you

This. I woke up and my 3G wasn't even on. I had to disable and enable data again to get connected.

Same problem here. Whenever my phone is in standby mode for a longer period of time (as far as I've seen it doesn't matter whether it's during the night or day), the data connection (3g) is disconnected.
On my previous phone, a desire Z, there was a setting 'data always on' which addressed this issue. This setting however seems to be missing on all android 4 phones.
**edit:
Contacted Dutch HTC support; they claim it's a feature. Hope they restore the setting in the future..

I have noticed this too this morning.
I woke this morning and went into the battery settings and you can see the graph that all data was shut off over night.
How do we fix this.

Piss. Wondered why it used virtually no battery overnight...

Exactly same here...just as u switch on the screen....it connects to wifi or 3g instantly...

I have received email overnight though....

I was thinking that maybe it was just the 3g/wifi connection which was going into a sleep mode after a long period of inactivity.
I've tried increasing my mail sync at night to once in 30 minutes to prevent the 3g connection from going to sleep and disconnecting. (had it at once in 4 hours)
Now when i wake up and turn the screen on, the 3g icon is already there, and my mail has been synced last in the previous 30 minutes.
Fixed it?

Same issue here, weird thing is that I can't seem to tie it down to either a specific battery-percentage nor a specific time of the day. It's really annoying though, as I would like my device to be connected 24/7. Tried setting a mail-account for 15 min update, so will see how much wifi/3g has been on tomorrow.
Edit: Definitely not a battery issue, but rather a time issue. Battery is at 80% (used the phone little today) and 3G/wifi has been disconnected for the past 2 hours even when mail is set to check every 15 min. I can see that for many people it's not important at night, but I wish we at least had the option to turn it off :/

Possible Fix
Download this app.. Minimaltext
https://play.google.com/store/apps/details?id=de.devmil.minimaltext&feature=search_result
Create a widget 1x1, under the tap behavior, select start another activity, then select an activity. Scroll now to settings, expand it, choose power saving setting..
Leave the rest default then press okay.
Click the widget and you will find some settings, including put data connection to sleep when screen is off. I haven't tried it. Hope this helps.

Not a bug!
This is not a bug, but a feature : scheduled standby mode
If on Sense 4.x, settings are similar to Sense 3.5, you should go into settings > power then scroll to standby mode. Default setting is auto, which means that the phone learns your sleeping phases and disable every wirless connections during this time when your screen is off, and enable it again automatically when you wake up (even if your screen is still off).
You can disable this feature, or (my favorite option) manually set the duration when you allow your phone to enter and exit deep standby mode.
(For me it's a great feature, as I really dislike having my phone producing airwaves close by my head when I'm sleeping. Before I went to Sense 3.5 on my DHD, I didn't have this option and had to enable plane mode before sleeping ant enter my PIN code every morning to exit plane mode, which was less convenient).

If you want to disable this, download smartsync disabler from the play store. Im pretty sure there is a thread on xda too with an app available to download.

...Or read my previous post... Market's bloatware is not needed, setting for this should be in power settings, as on Sense 3.5.

Anyone knows anything about this????

The issue was that the battery tracking in the phone was messed up. When you go to Settings>Power, the default setting for "Fast Boot" is on. This seems to mess up the way that battery drain is tracked. I fixed the issue by turning Fast Boot off, charging up the phone to 99% (it wouldn't reach 100, that's how bad it was messed up), then restarting it. Now, it works perfectly and easily gets me through the day with moderate/heavy usage; I watched a 30 min video streaming from youtube of wifi and lost only 7%.
The downside is now the phone takes 5 seconds longer to start up .
and one more problem:Every app I use stays in batery use with 4-5%.Worse is with phone when I finish phone call phone stays on 30-40% usage for long time 20-25min then goes to 12-15 and stays like that?????Any idea
I found this post can anyone tell me more about this how to turn off fastboot ????DO they mean on cwm fastboot or what????

What method do you use to kills apps? Closing (flicking swipe action) apps from your Recent Apps does NOT kill it. I also rather see it as "killed" BUT that's how they have designed HTC Sense 4.0
You need to use a Task Manager to actually kill any app. Hope this helps.

...
Im using task killer but I set it up that he kills apps when I lock screen but task killer cant kill phone app or Im wong????do I need to make security lvl to low ????Im talking about advanced task killer.
OR...I need to use task manager not a task kiler ????

AFAIK Task Manager works great. Also, they highly recommend NOT to use any kind of Task Killer at all with One X or Android ICS 4.0. I will post links to the thread that talks about Task Killer apps when/if i come across the thread.

Don't kill system apps, cause they boot right up, and then u got loop, of killing and booting and discharging batterie.

Task killers don't help. Swiping an app in task manager closes it just like exiting with the back button closes it. The phone doesn't charge to 100% as a safety feature.

time is not synced in the mornings by 5 minutes everyday

All, i'm having a huge problem. beginning last weekend, whenever I wake up I find my phone clock has become nearly 5 minutes slower.
Because of my sleep schedule on the weekdays, its always 5 minutes late by the time i wake up. strange thing is, within 10-15 min of my phone being "awake" I assume the auto clock sync corrects the wrong time and by the time i'm i'm driving to work the clock's time is right.
i tried turning off wifi one night i think a couple days ago to see if it was some type of strange wifi issue and i found that with wifi turned off, my phone was almost 20 minutes off on the time.
This has affected strangely my alarm clock as well and sometimes it doesn't even go off and i naturally wake up and check and it shows the screen where the alarm clock is running, asking me to "dismiss" or "snooze"
This is super cumbersome, is ANYONE else having this issue with the hox? my only conclusion is while i am sleeping and my phone is on standby for many hours something isn't quite doing its job. maybe something like the phone time being off, i don't know, like 30 seconds an hour or something. I'm still on 1.73.
during the day while my phone is turned on every 30 min to an hour, my clock is perfectly sync'ed.
please help.

turn off auto updating and manually set it - does it still happen?
it could be a conflict between phone time and network time, and the phone stops checking when asleep?

Are you using a custom kernel? Some kernels can have time slew issues. Most people don't notice it. I use Clocksync from the market to keep synced.

i've only rooted it for titanium back up. kernel is factory. i am definitely going to look into clocksync as well after tonight's test. thank you.

i can confirm after i turned off network clock sync that it indeed was not the problem and that there is something inherent in the software that is slowing down my clock on my phone overnight. thing is i don't have any crazy apps. this is so strange.
anyways i have downloaded ClockSync and seeing if this will fix the problem. thanks

NY Times

Anyone notice problems with the NY Times app recently? I noticed some high network activity out of my Note Pro over the last few days, and dug into it last night. Turned out, my tablet never went to deep sleep, and looking at battery usage, the NY Times app was behind only the OS and System.
I can't uninstall the NY Times, but I can revert to the factory image, and that seems to have put a halt to the network activity, and also the tablet is now going into deep sleep again. So it looks like it was an app update, somewhere along the way?

What's deep sleep as opposed to sleep as opposed to going into airplane mode?? Your posting about the ny times and sleep is difficult to understand.

Not difficult to understand at all, this is apparently a wake lock issue with the application.
Tapping the power button to turn off the screen puts the device in sleep mode but CPU speed still varies as background activity continues. Application processes can place wake locks on the CPU to keep it from going into deep sleep which is the lowest power consumption setting. A device that never goes into deep sleep will experience higher battery drain with the screen off for extended periods than one that does go into deep sleep. Sleep has nothing to do with airplane mode, which turns off all radios and has no direct impact on CPU.
First thing I would try with the NY Times app is turn off all notifications for it. Personally I don't use it and have it frozen so I can't verify the wake lock issue on my device.

Much better explanation than I could have given, thanks! So wish I could root my tablet (a Verizon...), feel like I'm trying to debug things with both hands tied behind my back!
So far, the NYT problem hasn't come back - can't freeze or uninstall it without root, but have removed it from Magazine UI and basically backed out all updates by restoring it to its factory image and clearing its data. BTW, it was set to only get updates every 4 hours. Obviously it had a different idea.

Yeah I hate it when apps get like that.
It's times like that where I'll use Greenify sparingly to push the misbehaving app into hibernation. Otherwise I'll just let android do it's thing.

A few days ago, I noticed the NY Times app only it's you view 10 articles for free every month. I was going to say, why not trash that garbage? It requires root, though, since it's actually a system app. That is just profoundly stupid.
At least Samsung didn't pick CNN as it's news app, amirite?
