Phone wakes up overnight causing battery drain

I charge my phone to 100% before bed, turn off the sync, and don't use it at all overnight. I'll wake up in the morning and it's drained down 15% or so without touching it. When I check my battery usage, it shows that about 4-5 hours after unplugging it, something wakes up the phone and keeps it awake causing a dip in the battery level. There aren't any apps that are doing it as the main battery user is the Android System.
Now, if I reboot the phone while still on the charger before bed and allow the phone to return to 100%, this drain doesn't happen. I'll wake up and have 95-97% battery.
Any help or ideas?
BTW: I'm running Calkulins ROM 2.8 with and EL29 but this has happened since before I rooted the phone.

Download betterbatterystats from the market. Let the phone sit overnight again and view partial wakelocks.
Or turn the phone's airplane mode on...

I'll try the app. I can't really use airplane mode because I need to phone on for emergencies. Thanks.

If you don't need data, you can turn that off along with sync. Calls will still come through

I'll try that too. I got the app today so I'll see what happens tonight when I don't reset before unplugging and check the drain.

Have you tried Lunesta?

Couldn't convince the phone to swallow the pill.
I figured it out with that app. Slacker Radio was the problem. I used the it during the day and didn't exit out from the app. I guess Android killed the process because it was idle for so long because it wasn't coming up in the Active Applications app but it was still active in the background. The app mentioned earlier showed me that Slacker was active for over 2 hours while the phone was sitting, screen off, overnight. That's why when I rebooted before bed, the drain didn't happen. I just have to make sure to exit out and close the app when I'm done with it. Thanks for the help.

Even exiting the app via the in app menu causes the problem. The only thing I've found to completely fix it is to either reboot the phone sometime after using the app or clearing the RAM via the included task manager. I sent an email to Slacker support and they told me to use the app menu to exit out, well that doesn't fix it. Hopefully it'll be addressed in a future update from them.

[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...

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.

Is this battery drain normal/reasonable?

I unplugged my phone before I went to bed to see how much it would drain overnight. I only slept for 5.5 hours. My phone had lost 16%. Is this normal?
I was connected to wifi, only thing I had syncing was Facebook for every 4 hours.
I forgot to screenshot the cpu times, but it spent a majority of the time in deep sleep and 384.
Also, what do the red bars mean in BBS?

Try disabling WiFi as well? Im guessing you dont need Facebook to sync while you sleep, just refresh it when you wake up. Noticed you clock down to 384mhz while screen off. odd how still took away a lot for only 5 hours.

I dont think clocking down helps that much. it doesnt stop the same processes from running, and it takes longer to run them with the lower processing power, especially when the phone has all night to do it /

According to your screenshots you have posted, that kakao talk app is in wakelock, keeping the phone from actually sleeping. Although the other stats seem to contradict this i would be willing to bet this is your problem. I would either disable it from syncing in the app, freezing the process, or somehow prevent it from running. I would put money on it improving battery life drastically. I cant be sure of this as i dont use betterbatterystats but i would suspect the red bar is the time spent in wakelock, while the cpu is supposedly in deep sleep.

That doesn't look normal. I get less than 1%/hour overnight. Though I don't use Facebook or Facebook app. I do have 2 Gmail accounts on auto sync. Weather widget sync/hour. Field trip and Google+ sync enabled and wifi is always on when I'm at home.

Weird drain overnight

Hey guys, I got this weird drain of about 1%/ hr over a period of 6 hours overnight with 2g data and auto sync on, the previous night with 3g data on I drained only 2% in 9 hours.
Apparently my phone has one hours of being kept awake by a wake lock named
mdm_hsic_pm0
And another hour by
Battery_monitor
Does this happen to anyone else?

Same here on the note 2 with Sprint but I loose about 2-3% per hour. Go to sleep with 100% wake up in the morning with 80-85% left....

This is the only thing i found in bbs thread
mdm_hsic_pm0 is afaik the same as l2 Hasic, just a new name under Jellybean, so its traffic related, i would keen an eye on my background activity..

battery monitor wakelock is almost related to the BBS

ssame thing happening to me..should i change kernel ?

i have same battery monitor drain and wlan_wake

I use to have battery drain on my GT-N7100 (and overheating problem). What turned out was that the Gmail sync on one of my accounts was going in a loop and never ending. When I fixed it, all went back to normal.

What rom / Kernels you peeps running? I had this once, flashed a different rom and no problem. Currently running Omega 7.1 with excellent battery life over night.

Mdm hsic is related to mobile data and this includes both 3g and wifi. Turn off 3g when not in use and you will see this wakelock going down. THe other one is nothing to worry

First, when you set the phone for the first time it does a lot of initial activity that may cause drainage.
In my case, I have 3 gmail.com accounts on my phone. I only need one of them to sync email, Picasa, contacts and calendars. On the other 2 I need only email. The phone was syncing everything on all accounts: in addition to the above also Google Photos, Play Magazines,Play Music, Internet, Keep and People Details.
As soon as I disabled all the unwanted syncing, things improved.

Abysmal battery life on JB

I updated to JB last night, fully charged my phone, unplugged it and then went to sleep. When I woke up I only had 50% battery left, previously on ICS when the phone was idle over night it used between 2-5% max.
I then charged the phone again this morning and now 3hrs 10mins later, I'm already down to 66% and I have hardly used the phone. It's showing as:
Whatsapp 36% !?!
Android OS 17%
Android System 16%
Facebook 7%
HTC Sense 6%
Mediaserver 4%
Camera 3%
Is anyone else having any problems? With ICS I would charge my phone in the morning at work and it would easily last until the following morning, unless I was heavily using Facebook or playing a game. I thought JB was supposed to improve the battery life, not make it worse.

Give it a few charging cycles before complaining.
Have you rebooted the phone since the update.?

Some apps still are not quite complitable with jb,especially with new HTC sense libs or api.

Not me personally, but it did reboot by itself randomly. It's never done that on ICS. I think I'll do as you suggest, give it another day or so. If it still hasn't improved I'll try a factory reset.
What does the Power Saver option actually do? Does it switch off all data sync, lower the screen brightness etc?

Do a full wipe. Some apps could be screwed up while updating.

Power saving saps my power.
3 hours and I lost 20% quick. Turn off power saver and I'm actually saving power.

Hmm I actually think power saver is an amazing feature. 2 hours gone by and I just lost 6% battery (normal usage: message, whatsapp, maps, xda). Even though typing felt weird because no vibrations.

I think they have paired the app with the screen time and gives you a total percentage.
No screen time hours is pretty ****ty.

Most likely an app that isn't backing off nicely. When an app finds your data/Wi-Fi is off is probably getting in a panic that it can't call the mothership (or download some ads!) and is waking your phone or keeping it awake constantly while it tries and tries.
That app would cause the same issue if you turned off data and Wi-Fi manually.

Try Nova, I personally find it better than Apex.

So I installed android revolution 15.0 and the battery doesn't seem to be good at all... Don't know if its a JB thing or this particual Rom. When I check the usage number on power section, it says android os has a 2 hr wake up time... I also installed betterbattery stats and I am getting this wl1271_wake under the kernel section and this weird surfaceflinger under the processes section... Any insight would be helpful, thanks

I performed a factory reset last night - well the new equivalent in JB, which is go to backup and reset the phone.
After the reset, I setup my Google, Exchange, Hotmail and Facebook sync. The only app I installed was Whatsapp. Managed to get the phone to 72% charge before unplugging and going to sleep, I also made sure the initial syncs had all completed before unplugging the charger. This time it went from 72% to 30%, so 40% used while sleeping instead of 50%.
Looking at the stats, I think the battery counters are screwed up. When I first checked this morning, it showed Whatsapp had used just 2%. 10 mins later after a couple of messages, the battery had dropped to 28% and Whatsapp then showed as 32%.
Android OS never used to show much usage, the screen was always the thirstiest, but this morning it Android OS showed as ~30% which then dropped to 22% after using Whatsapp. Perhaps this is due to the screen time being integrated into the app counters as mickfitz said.
As you can see from the pic below, Whatsapp doesn't appear to be keeping the phone alive during the night as Phil suggested:
Surely others here use Whatsapp? Is no one else getting massive battery drain since the OTA JB update?
The only other things I can think of are the company policy settings which are applied to the phone when I setup my Exchange account, or Google Now - but for this I'm just using the default settings.
[EDIT] I'm not using Power Saver mode btw and I don't want to if it shuts off data while idle - it will mean I don't receive Whatsapp alerts
[EDIT 2] I've just had a proper look at the 2nd screenshot. The line chart doesn't match up with the battery % shown. It was definitely at 72% when I went to sleep yet the chart only shows 50%. I'll leave it charging all evening and check the line chart to make sure it's at 100% then give it another go tonight.

not sure if this app will help us to get a clearer picture of what is happening..
