Wifi drain or just normal?

Hi,
New to the note 2, not new to being a flashaholic. Being very tame atm and only using stock rom (rooted) with no Cwm.
Strangely I get about 10% drain overnight. Got better batt app but doesn't really show much except wifi is/was on.. And this audio_out_2.
Is that normal on stock rom? On the dhd it was more like 1-2% on experimental roms

Disable stuff manually or use Juice Defender Ultimate (3.9.6). I use JD and never turn anything of manually.

I do have sync on. I guess what people are trying to say it's pretty standard on stock rom and I'm in need of an awesome custom rom to flash?
I used jd ages ago but configuring is a bit of a pain.. I may try it again till awesome roms comes out.

Check you applications, I have 90 apps installed and only have 0.5-0.6% per hour while sleeping with sync on.
Tonight, for example, I left wild blood downloading the last 200 mb it needed.
It took like 5 minutes, then I woke up and I noticed that it kept the device awake for 6 hours even after finishing the download, Battery went for 50 to 43% in 6 hours..
Custom roms won't make a great difference.. Maybe removing some bloatware will do, but you can stay on stock imho.

Just a question, do you, by any chance, have SIM plugged in? I observed quite higher power drain (overnight) when I did not have SIM inside.

Yeah, I have sim in at all times.. Erm apps wise, I've not added any new ones before my upgrade so I guess if there is an issue it would be some bloat apps? I tried to freeze as many as I dare using tb. (well, I followed the script of apps to delete on the other thread).
What app did you used to find what apps drained x amount per hr? That seems like a clever one
Sent from my GT-N7105 using Tapatalk 2

Yeah, I have similar experiences. My phone drains around 10% overnight with no apps in the background and wifi off.
So what I'm doing and it seems that it has marginally helped is:
1. Turn off Sync
2. Turn off Notifications from Email accounts as these come in all the time even overnight and the notification process and the Blue LED will drain the battery
3. Decrease screen brightness to around 40%
4. Turn on wifi only when needed
5. Disable some of the apps I don't use (Chaton, Yahoo Finance and Yahoo news, S Suggest and Samsung Store, etc)
Now I get about of 1 1/2 day of regular use.

Think I found the culprit..
Has anyone got motion feature turned on? There's that sneak wake function ticked on mine as default, I switched that off and I only got 4% drain overnight.
Perhaps others may want to give this a go and see if it helps?

4-5% per night is what I see on my GT-N7100 (intl), with Wifi on, BT off, GPS off, NFC off, Sync on.
I got Motion on though, with following features: "Tilt to zoom", "Palm swipe to capture", "Palm touch to mute/pause". I am not sure which one is supposed to be "sneak wake" one .
But now, when thinking about it, I realize I do not need any of those, so I am going to turn Motion off completely to see if it has any impact.

Since upgrading to 4.1.2 battery drain in deep sleep

Hi Guys,
I updated to 4.1.2 few days ago and since then I'm experiencing a battery drain in deep sleep mode usually 3-4% per hour.
I froze all the "safe" apps via Titanium backup, and also removed some bloatware (chat on, google+ etc..), also I disabled the Google location services and the WIFI during sleep it set to off...still no improvement, could you kindly advise what can I try next? as I'm desperate and if I won't find any solution I'll just downgrade back to 4.1.1...
Thanks!

Similar to you, I have tweaks 4.1.2 so much. Removed all the bloatware, disabled google now/locations, etc etc. Stopped media scanning too and checked to see all the wakelocks and try eliminating the top ones.
Basically, unless I'm missing something very obvious, there is absolutely NO WAY whatsoever to stop the battery drain. Software is the problem, and I would suggest reverting back to 4.1.1 unless Samsung or Google sort this mess out.

Hi
I have the same Problem with battery drain in deep sleep mode!
I contacted Samsung, they told me it's the old system! (4.1.1)
I should do a full reset.

When restoring apps using TB, you should always install apks only and not include data.

My issue I figure out is the wifi that never turns off even if theres no app on and screen is off. (smart wifi not working)
My solution is this: https://play.google.com/store/apps/...xLDEsImNvbS5hc2tzdmVuLmJldHRlcndpZmlvbm9mZiJd
I tried a lot of apps, and this is turning off the wifi properly and not used, them my phone keeps on Edge that dont waste juice.
is getting a lot better, but 4.1.2 seems to suck more bat than 4.1.1

Try to drain your battery till 2% and then fully charge it. For some reason it works everytime for me

[Q] Rom/Kernel issue OR Battery?

Hi all
After sitting with my stock SGS4 (i9505) for a few months I decided to root (as i had my N7000 and HTC Desire).
About the same time as this my phone began turning off seemingly randomly. At first i thought this may be a ROM/Kernel issue but I have tried a couple including Stock(rooted), Carbon and the GooglePlay Rom. The same thing happens for all of them.
Once off, the phone boots to splash screen then turns off. This cycles. I remove the battery and the phone will turn on, sometimes showing a SIGNIFICANT apparent drop in battery (90% reduces to 3% during this single on/off cycle). A quick charge and restart will often cause the rebooted phone to read the battery at 90% again.
The battery does appear slightly swollen and i'm curious if anyone could shed any light on:
1) does this seem a battery / firmware issue and
2) any suggestions?
Thanks in advance for any help you can offer!
Currently: GooglePlay Rom 4.2.2 PhilZTouch Recovery
Regards
Warnoceros

If you're saying the battery is "swollen" it probably is a battery issue IMO. Especially if you're having problems on every ROM you've tried.
Have you tried going back to stock to see if it's still happening?

Hi
Thanks for replying. I'm downloading stock now so will report in the morning.

Bad battery.
Sent from my SGH-M919 using Tapatalk 4

Hi,
So, went back to stock (binary counter has moved up unfortunately - didnt read into that before hand). Was still rebooting. Have replaced battery and this seems to have done the trick for the time being. I noticed that the unit did not reset until my google accout restored apps to the phone so there is still a chance it was a bad app i suppose.
Most likely the battery though
Thanks

Help! Random shut down and battery issues

I'm experiencing sudden shut downs when I take a picture with my phones camera, especially if the flash is used. It just turns off without warning.
The battery has also started to suddenly drop a lot in percentage sometimes , and yesterday phone just turned off at around 20%, because battery was apparently empty....
Could this be a faulty battery or software problem? I'm using stock Rom and stock kernel. And have never had any problems before

Factory reset if it doesn't work, warranty service..

Same problem here, phone shuts down at 20-30% when LTE is on; after restart it shows 0%.
I'm pretty sure it's a problem with the battery

I had that problem too, but after update my custom rom that problem don't occure anymore. I haven't check it with almost empty battery, maybe I'll try it soon..

Am I the only one who thinks that is pretty strange this issue being reported a lot of times lately ? I didnt have issues with my battery before, but now I have the exact same problem with the flashlight. But when I use an app of flashlight the phone doesnt turn off...

Shutdown
Hey
I'm having the same problem but my phone shuts down at 40% and won't start again. I have got a new battery and done a factory reset, but nether has worked. The phone is 3 years old, so change the system won't be a problem with the warranty.

[Q] [HELP] Battery remains constant and drains to 0 rapidly

I am using XOLO Q100i mobile which i purchased two months back. Initially it was having android 4.2.2. Last week I got update for 4.4.2 and since then I am facing this battery problem where, the battery percentage remains constant for long period time and after that it rapidly drops to 0 and switches off.
I am facing this problem only after I had updated it to 4.4.2 (it was system update, i didn't do it manually)
One example case is, even after using browser with 3G internet for 30 mins, the battery remains at same percentage.
Yesterday I even did factory data reset but still this problem is persisting.
Any solution for this problem?.

Its not the battery issue. Its the common problem of android KitKat version. Its the issue of Battery Stat permissions. One solution is Using Xposed framework along with BatteryStat permission module installed. All statistics will be displayed correctly. But need to root your Device. Another check is What Xolo Power showing and what default android battery stats are showing.
Best of Luck

Thanks so much for the shout out.
Since the phone is still under warranty period, i haven't rooted the phone yet.
Xolo power is showing exactly same percentage as shown in nav bar.
Anyother solution?

Yes it's a problem but it occurs very rarely with me like twice or thrice in a month.

as far of other solution
Customer care support for cell under Warranty sucks coz Xolo care are too lame
Instead just root your device
And Xolo never checks if your device is rooted or not.
After rooting go to /data/system. Delete batterystats.bin
Do not charge your phone unroll it hits zero and shuts off automatically
Then charge it..
Install battery calibrator from market
And hit calibrate in that app after reaching 100%
Low battery wrong stats won't bother you again

Let ur phone shut down automatically when it's battery gets to zero and then connect it to charger to let it recharge fully without switching it on. Try this a 2 or 3 times. Hope it helps then.
