[Q] Battery problem, stand-by

Hi all. Here's the thing. Yesterday i've charge my galaxy (up to about 90%) set up alarm for morning, and going to sleep. In morning my battery was empty, i don't have idea why, because i push power button to "sand-by" on my phone in that night. What's the deal? Stand-up time was about 7h - is there any fix for that, or maybe it's some kind of bug? Oh that was my first stand-by mode for so long time (phone is pretty brand new, about 3 days from purchase)
Few words about phone:
-i9000XXJF5
-no root, flash, and any modyfication
-in phone i have about 20 instaled apps, 4 widgets on
-no task killer
-about 3 days from purchase phone
-home screen set on LauncherPro
Any advise guys?
Sorry for my english.

There must be some app draining your battery. My SGS usually drops only 4% in battery percentage during the night (I turn of 3g at night using SwitchPro, and I'm on JM2).

Have you installed the latest Facebook for Android app? It drains battery a lot because it keeps the phone awake 100% of the time. Uninstall it, or at least Log out from within the app, so that your phone can sleep in idle mode.

Yes... the problems of Android... I use CPUMonitorMini to keep an eye if any apps go rogue and start hitting my CPU 100% and draining my battery dry.

No i don't have this app. Maybe the problem was autosynch option ON.

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.

Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.

Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.

Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??

You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.

Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.

CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?

Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.

I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note

I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

[Q] Battery drain in deep sleep

Hello,
I am asking this question as to confirm if my tablet needs to be sent to warranty or this is a normal behavior to you other people reading this post.
I have stock 4.2.1 rooted on a nexus 7 16gb version
When I lock the screen the device enters deep sleep => I can verify this by using CPU Spy, it says that in 30min of screen off, 28 minutes were spent in deep sleep
Using Battery monitor widget with refresh rate at 1min I can look at the log and see that the tablet had a constant drain of 50 to 94 mah during those 30 minutes. Only after 2-3 hours the device starts to have a drain of 2-3 mah (if the screen is off)
Wireless, Bluetooth, Gps are turned off.
If you think I may have omitted some things in my test procedure please share some info, otherwise please tell me if you also encounter this problem
A good day !

background apps could cause drain, not even apps you opened. like the facebook app is notorious for it.

Hmm, normally when I had the HTC HD2 when it was in deep sleep it had a drain of 2-3mah - battery monitor widget was checking every 1min
Now with the Nexus 7 the drain is 50-94 in deep sleep, do you think this would be a normal behavior ?

I can relate
I get the same type of behavior on my Nexus 7 16GB wifi only model. Mine does not seem to be due to an app either, as the main battery use is Google related (Play store, or Google services, etc.). Take today for example. I charged my Nexus 7 overnight, verified that it was reporting fully charged when I got up, then I put it to sleep and set it aside to take to work and didn't use it again. When I got to work 2.5 hours later I turned it on and it was at about 83% battery. I lost almost 20% battery in 2.5 hours without even using the tablet. I attached a screenshot - today's culprit was Android OS (I took the screenshot a couple of hours later at work). This behavior started after upgrading to 4.2 - it never did this on 4.1.
Oddly enough, I don't get this type of drain if there's no wifi connection, even if wifi is left on and there's a wifi signal that it's just not connected to. When I get someplace with wifi, the battery drain starts again.

Terrible battery life? What gives?

Hey guys...
Just here to say that I unplugged this phone at around 5 in the morning, and around 5 hours later its already down to 74%.
What did I do? Only about 10 minutes of mobile hotspot, a 2 minute phone call, and three text messages. The rest just idling...
1/4th of my battery life for just that?
What the heck?
Everything is disabled and the screen brightness is low... Whats the matter with this phone?

Looks like something is keeping your device awake.
Can you please add some screenshots of your battery graph?
In addition, you can try to boot into safe mode. If your problem is gone in safe mode, a third party app is interfering.

If you're rooted, try installing Wakelock detector or BBS (Better Battery Stats) and check out what is waking up your device.

If you use Gas Buddy, it was known to be causing massive bluetooth wakelocks. Either uninstall it or update it to the latest version.
Set your wifi to 2.4 ghz only. On 6.0 and 6.0.1, the 5 ghz band has been causing abnormal battery drain and keeping phones from entering doze mode. Here's the issue being reported: https://code.google.com/p/android/issues/detail?id=197460
If neither of these make a big improvement, you'll have to use your battery stats (and if rooted, use Better Battery Stats or Wakelock Detector) to specifically see what's keeping the phone awake. In either of these apps, filter the view by "Alarms" or "wakeup triggers" and you'll see what the heavy hitters are.
Be sure to go into Location>Settings and turn off wifi and bluetooth scanning.

Hi.the maps app isvuding WiFi and gps even though both are disabled and I'm not using it... Any ideas?

Verizon S7 Edge Battery Life Terrible

And there's nothing I can do about it. I only have a gear s2 connected at all times and wifi and mobile data off whenever possible. Before I leave to the gym battery is at 44%. After the car ride there it drops one percent. I unlock the phone, connect my powerbeats, and open youtube and there go another 5%. After a YouTube video there is 7% drain. About a 10 minute video too. Leaving the gym and hour later and I see a maybe 20% battery loss. I don't know how people with regular S7s get 4-5 hours SOT because I get only 3.5 maximum. I bought the edge looking for better battery life but it's practically no different than my S5. If anyone knows a magic trick to this, I need to know now because this is extremely annoying.

IF you got the device from an official retailer, just return and get a new replacement. Losing 7% watching a 10' video is not right even with max brightness. You can fix the standby drain by using Forcedoze (which helped reduce my standby drain by 50% to about 1% every 2 hours). 3.5 hours SOT is terrible even with max brightness. Just get a replacement please. It's not worth the time and frustration.
IF you don't have the option of getting a replacement. Forcedoze can help with the standby drain. Factory reset, set up normally (personally, I just turn off bluetooth NFC location and turn them on when needed), and hope that your terrible screen on time is software related.

Do you think it might be my location by any chance? Maybe the service in my area causes this drain. I also have gps on because of my gear s2 but I can turn that off and see what happens. GSAM tells me the in the past 30 minutes the drain rate is 15% per hour. I browsed the Internet a bit and have been using it the whole time. I'll try to also do a full battery drain test on geekbench with full brightness and see what it tells me.

It's a good possibility. I have a fairly weak signal where I am most of the day and only get about 4-5 hours of SOT. I have all radios off except WiFi and data when needed. Still with my usage I only charge every 2 to 3 days. I don't get the drain like you do from watching youtube though.

My battery life also sucks. I barely use my phone during the day and it almost dead when I go to sleep. Most of the day I am connected to wifi between my work or home. My old htc m8 one could last 40 hours. I think part of the problem is because I do not have root on this phone. I kind of regret switching because I cannot get root. I cannot use applications to adjust cpu or control my wifi, data and to turn off apps from starting automatically. I think tonight I am going to try and calibrate my battery.

I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....

Guys, I had terrible battery life when I first got the phone. Off the charger at 6am, under 20% by 5pm... Follow my steps below and I bet your battery will do a 180 and be very nice. Mine gets me 35-40+ hours on a charge.
Disable the bloat apps you don't want in app manager.
Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

I installed forcedoze and did the adb non-root command and now my phone's battery is holding up better. I think the phone was just sleeping.

It's ridiculous one has to do all this to get closer to acceptable battery life.
Google and SEC should be ashamed of themselves!
It's not just VZW devices either. AT&T are just as bad.
I've given up on trying to get acceptable standby drain and just let the device live on a wireless charger.

You need to turn off all radios when you go to sleep for the device to enter deep sleep. I had the same problem and when I started turning off wifi and mobile data for the night GSAM reported deep sleep and I was only losing 3% per night.
