ICS update Battery Issues

Alright so like many other people on this and other forums, I updated to ics 4.0.3 two days ago and been experiencing battery issues since. But my battery issue is a bit different from what I've read about. My note has no problem going into deep sleep, when i go sleep and wake up deep sleep is at 98-99% and my battery drains about 1%. But when I turn on my phone and start using it no matter what I do, the battery drains about 1% every 3-5 minutes.
Phone settings:
- I always have my brightness at 0 and have screen filter on to make it even less bright(even though battery drains about the same with or without this on) (batter settings still show that screen is taking up most of the battery)
- With wifi on or off battery drains just as fast.
- I havnt started my new data plan yet so im always on airplane mode( battery drains the same with this on or off)
- My note was never rooted
- I basicly have no widgets on anymore because i deleted most of them but doesnt help battery life.
- With power savings on or off battery still drains the same amount
- The only apps i have installed after ics are ones from googe play(netflix, chrome, and other simple apps)/ i deleted my emulators and other apps that iv'e downloaded and installed
Can anyone please help me with this issue

You are on Stock ICS ? Go to Settings>Battery And Post the Screenshot Here. It will help us to determine the exact situation..

Sorry I'm new im guessing stock ics means official release from kies, then yes. I dont know how useful these battery ss will be because a lot of the time im either idle or charging.

Did you perform a hard reset on your device after the update?
if not, then see if you can try it and get back again with your screenshots.. don't forget to do some re-calibration also on your battery. This works on my end before. Not sure if it works on yours, but hey.. there's no harm in trying right? just give it a shot bud...
Cheers!

Turn off the sync. Kill Background applications and See if it works for you...
Also download Battery Calibration from play store... Open it when its fully charged and start calibration... Let your phone battery fully drained and then charge it again to full without pauses...

I've been thinking about it and it would be my last option to do a hard reset because i read that some people bricked their phone by doing it. =/

I have sync accounts off and i only have my gmail account in the options to turn it on unless you mean something else.
I'm not really sure how to kill background applications is it the cashed applications? because ive tried killing running + cashed.
I just installed battery calibration and it says i must root my phone 1st =/

Wtf are you trying to brick op's phone? You should get a warning..
Op never ever ever ever ever ever do a factory reset from ANY ics stock kernel.. It will get your phone bricked.. Or maybe but just maybe not? Anyways will you take the chance?
I was on 4.0.3 stock and yeah the battery it's horrible.. Don't know why the phone barely goes deep sleep.. Check this with cpu spy free app from market
Since the phone upgraded itself to 4.0.4 I have been able to run 14 hours with 5 hours screen and the phone its always on deep sleep
Sent from my GT-N7000 using xda premium

yea i knew theres a huge risk involved =/ , is there anyway i can update to 4.0.4 because it's not showing up on kies

Yeah following the several guides around.. They all lead you to download 4.0.4 and a gingerbread rom from Sammobile, downgrading your phone to gingerbread by flashing it via odin and then flashing ics 4.0.4 via odin also .. So go ahead and read some..

Check Android Development Section...

cpuspy and betterbatterystats to check partial wakelocks and whats keeping phone awake. A gazilion threads on that. read them. You need these as Samsungs analytical view state nothing usefull, they need to fire the designer of that.
Next to this I see lot of screen on time, how much time roughly is that in total, you are actually using device?
Sent from my GT-N7000 using Tapatalk 2

my phone doesn't have the deep sleep problem people have. my on screen time is about 6 hours before it drains completely and by on screen time it could be on the home screen with no wifi/net and no apps running with just the screen on, and the battery would still go down 1% every 3-5 min

So ics 4.0.4 came out for the UK version of note so i updated via kies. This didnt fix battery life at all, in addition iit came with another bug where my phone gets hot and drains battery when turn off the screen after playing any media file....So my question now is can i root 4.0.4 if i have the Emmc bug?

Too fast battery drain

Well that translates to 33 hours of battery life so that's pretty good
This phone is different from others in that the lowest frequency (384mhz) is very high (my nexus 7 stays at 104mhz a lot), so minimizing the number of apps that make use of the phone when it's locked is key, as they would make it run at 384mhz, stamina mode is good with this but I assume you already have it on
So try to search for apps that use services that always run in the background and uninstall the ones you don't use very often

The same thing happened to my SP but only for 3-4 days after flashing a rom, then it was stable and the battery decreased from 100 to 15% after 2 days (light-use) or 24 hours (3G and Location based Wifi were on, without Stamina or Low battery mode enabled).
So, have u flashed rom already?

1% in 20 minutes when display is off. i charge my phone after 15-17 hours. that's how much it actually lasts.
Stamina mode is not enabled. i will try with it too in few days. thanks for the advice though

It's interesting to do experiment with these Mods, but sometimes we have to pay the price by time and even brick!

[Guide] Solve Standby and Android system Drain

I will give you 3 options to solve android system drain and it will 100% solve un-necessary drains.
1st Method this most probably solve issue
*Don't use fingerprint scanner use Face unlock or pattern
Note: If you will use fingerprint scanner it will give you alot of wakelocks because fingerprint scanner detects very little dust(which barely you can see with eyes) not only fingers. If you have phone in your jeans or trouser pocket it will drain battery 100%. Device will also heat while you get cdfinger wakelocks almost 5000+ in 10 minutes.
2nd Method Re-calibrate battery
Charge to 100% and use untill 0% . Charge while Mobile switch off upto 100 and use again do this 2 times.
3rd Method
Install full firmware from asus site copy this file to root directory and reboot and you will see update notification.
Note:This is for stock recovery and will wipe all data.
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZB601KL/UL-ASUS_X00T-WW-15.2016.1805.318-user.zip
Thanks for reading hope this will help someone. I found this solution my self by detecting wakelock and flashed full firmware i did not get any drain later.

Try this little trick which worked for me real good. After charging the device, restart it and go to Android system app info and trun off background activity (if it is already turned off turn on and off immediately). Do this every time you charge the device. Share your experience if you try it.

It doesn't do anything look at the wakelock detail its the faulty fingerprint scanner and stopping or changing system activity will give you negative effects on overall usability.

Recalibrating the battery may fixed the problem, but to completely fix it you probably want to switch to another ROM completely, plus installing stuff like Amplify + Greenify. You do need to root your phone for this. Don't ask me which ROM though since I'm on stock myself and too lazy to go through that process again for now. Maybe sometimes early next year we'll see.

Its Normal wakelock while using phone or having data connection or wifi connected and only problem is cdfinger wakelock which heats phone and eats a lot of battery and can not be solved by any app. For ex greenify. Ampify etc only can be fixed by asus by making changes in kernel.

Question Battery draining a bit too fast

Hi!
I'm experiencing some battery draining problems for a few months.
Overnight it uses up to about 15% and during the day with about 1h30min SOT it's down like 30%. I factory reset it, debloated it, dark mode on, Naptime with aggressive doze mode on and restricted almost all apps from running in the background with no difference.
I'm running on 12.5.4 global. Sometimes cell standby uses as much as 500 mAh.
When the battery is full it says "about 52 h 34 m left" no matter if I'm using fast or slow charging. Is this normal? I'm attaching some screen shots.

No. Unfortunately this seems to be the worst phone I have gotten so far and it's one of the expensive ones I bought. I also have problems with it not updating even though I did factory reset and tried to use select update package.

I have flashed the latest Lineage OS a week ago and the battery life is very good! The best of all MIUI or AOSP ROMs I have flashed to the moment!
At night the phone is in sleeping mode and the battery at morning is almost the same as it was at the evening, with WiFi, Bluethoot and Location switched ON - I haven't really tested how much exactly percents it tekes during the night, but I think that it's not more than 2-3% for the night.

Below are some stats from the latest Lineage OS
3% for almost 8 hours
I didn't get any problems with the Alarm and the deep sleep mode!

Overnight drain is too high. It's 10% even after enabling scheduled power off/on feature. Phone remains powered off for 4-5hrs at night still 10% of overnight drain is too much

2% here for more than 8 hours

That's aosp bruh. I should switch soon.

battery values are in the kernel, u can go /sys/class/power_supply/bms and search the "charge_full" value. if you battery are draining, maybe u have more values in this file, try with less mAh value, example: default value to 3300mAh is 3300000.
After change the values, try calibrate again, this worked for me

it shows me 3138000, what sould I change it to and can someone explain to me what does calibrate mean?

try to change a minor value, example 3070000, and calibrate the battery. Use the phone without turn off the screen, until the screen turns off, If the phone turns off before the battery indicator reaches 0%, that could be the reason for your battery drain, try modifies "charge_full" values to get the real value of your battery.

Btw, usage after 2 days, now i can say that cell standby issue is fixed.

You should note on your device, how long it used and healthy of battery and hardware?
1. Check battery healthy, if it was bad or limited cycle charged. Replace and test again.
2. Check hardware such as main board and other circuit. Some part was damage and infect can cause battery issue.
3. Try hard reset and select 2G only to save battery.
It was happened on my device and I did check, it was defective on main board. I replace a new main board and the problem has been solved.
