For the last three days, I am losing around 10% battery overnight (roughly 8 hours sleep).
I've been checking my battery statistics and it seems the culprit is UCCW Alarm Manager. Please see attached image.
Does anybody know how this can be remedied?

Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...
As title, has anyone experienced this? If I shut it down when finished with (yes definitely shutting it down and not putting it into sleep mode).. I come back to it in the mornings, boot it up, once loaded it shows around 60% ish battery left...
I shut it down to save battery, but I'm pretty sure it wouldn't use as much just being sat there!
40% overnight is massive, the battery icon on the status bar does not seem to update that quickly. Maybe its not really at full charge when you turn it off. I only lose 10-15% overnight in sleep mode.
Yeah!
I also lose up to 20% in sleep mode overnight.
But I experienced other strange battery behaviour.
Uptime 3 days:
- Day 1: 2h playing games (86% at complete shutdown)
- Day 2: 2h playing games (66% at complete shutdown)
- Day 3: at boot 20% --> WTH?!
So, yeah I also experienced this, but it was one-time only (yesterday). Or I wasn't paying attention because the tablet isn't mine.
Don't know!
EDIT: After 2 days (day 5) of complete shutdown the tablet was still working for 15 minutes with only 2% battery left. It's now being recharged.
I think the battery status is corrupt and needs to be reset.
I think it can be done with deletion of "/data/system/batterystats.bin" file (ROOT users only). --> I didn't try this method myself!
Hello. I'm making this thread because I had several battery issues where my battery laste 5 hours and 44 minutes in standby.
If you follow my threath in this link you'll see that after a factory reset i managed to get full 24 hours with regular usage.
Well the thing is yesterday I made my minimalistic text widget to show me battery %, battery temp. and battery health... went to bed and when i woke up the phone was dead, when i got it charge enough to turn it on i notice that lasted 5:44 minutes and it was in standby all night...
So today I'm taking my widget off and let's see how it goes.
I'm running Stock 2.3.4 UHKI1.
I'll let you know how this test goes.
I've used minimalistic text since I got my phone as a clock widget and a weather widget set to update every hour (both on different pages), I've never had drain like you've been experiencing.
I bought my Note 3 in December from a Samsung Smart Cafe. The phone was amazing throughout the last few months. 2 days on medium usage, amazing WiFi connectivity, awesome gaming experience.
However, 3 nights back I had left the phone (at 50% battery) and gone to bed around 23.00 hours. The next morning I woke up late at exactly 10.00 hrs. When I went to check for any missed calls I found that the battery had completely drained off and the phone was dead. I turned it back on t see that the battery percentage was 1%.
I want to clear out that the following are deactivated on my phone:
1) S-Voice
2) Wake up in lock Screen
When I checked the battery stats I found that the screen was using 56% of the battery. How could that possible be when the screen was switched off the whole time.
Since then every night there has been a drain of about 46% every night. Earlier it used to be only 2-3%.
Could you guys please help me out here? Really tensed
P.S: Last night I left the phone on flight mode and went to sleep. The battery drain was only 1%.
Guys! It happened last night again. This time around, the battery drop-out was around 40%.
Please help me out on this. Any kind of suggestion would be awesome.
Install app called gsam from Google play, one of your app may not allowing your phone to go on deep sleep. If you have installed any app recently try to uninstall.

Hey, the most recent apps that I had installed before the battery went bonkers were:
1) Truecaller
2) BosonX
3) Freeze
I uninstalled all of the three apps.
I have installed GSam battery monitor and the main stat that is abnormal according to me is that the battery discharges 43% even when the screen is off. I have a radio signal usage of about 42% which I think is pretty normal and I do not have bad reception.
Still, last night the battery went down to 80% from a full charged state of 100.

Let Gsam to monitor for two or three more complete charge & discharge cycle so u may come to know where is the problem, some time ext sd card also causing battery drain problem, if u have than try to use phone without sd card for couple of days.
I have had my phone a little over a week. I don't remember changing anything major in the last few days but I must have unintentionally done something which is causing excessive idle drain. All I remember doing is turning off some apps from being allowed to run when closed. It went from estimated 100+ hours on full charge to losing a ton in a day of basically no use (checking email a few times, looking at the weather a few times, sending a few texts). I installed GSam after trying to google what was wrong so I don't know what it looked like before.
Used 48% in 1d 13h | 1.3%/h 8h40m active
Screen 3%
Phone Radio 3%
Wifi Active 5%
Held Awake 26%
App Usage 64% > Android System 35.1% GSam 16% Kernel 7.2%
I did give it extra permissions in ADB but it still doesn't seem to give me extra info about what part of Android System is being a hog.
