Battery Drains during Standby Mode

Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.

Any feedback or comment on this matter would be really much appreciated. Thanks!

From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!

Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes

Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.

Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.

Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!

i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??

You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.

Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.

thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

@TempusFudgeIt
That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.

Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?

I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!

15-25% overnight battery drain versus 3-4%

According to the Battery thread in this forum, some people experience a high overnight battery drain, and some get a low one.
I am currently a member of the high club. For battery testing, I have most things turned off, like location services and google now. Last night overnight drain (8 hours) took the battery from 76% to 58%... 18%. On my previous phone, the HTC One, the overnight drain would be around 6%.
I am curious about the people who are getting low (~5%) overnight drains. Do they all have Wifi off? What is their secret?! Do tell.

Install better battery stats to monitor what's going on. I think the one night I left it off charge over night I lost maybe 6-8% but I slept for like 10+ hours. This is with google now on, gps on, wifi on.
What i'm testing now that I think will actually improve batt life is having wifi turn off when display is off (unless plugged in). I think I noticed less idle drain at home when I did this but it was temporary. Giving it a shot over a few days now.

I leave wifi on and I get less than 5% drain. Nothing syncs when my screen is off except notification weather pro every two hours and Yahoo weather

Personally I think the X and new droids have idle drain issues. Even when better battery stats shows nearly 100% deep sleep overnight, I still lose 8-10%. In comparison, on my HTC One mini, which is setup EXACTLY the same as my X in terms of installed apps, syncing accounts, running services, etc., I lose only 2-3% overnight. The number of people complaining about the issue seems to confirm it is more widespread than on other recent phones, as do the countless screenshots showing unusually high android OS usage in battery stats.

I honestly believe it will be patched with the Camera.

I'm having the same issue. People are reporting crazy battery stats with like 20+ hours of use 2+ hours of screen on and like 20% battery left. I get MAYBE 12 hours of use and 2 hours of screen on and 20-25% left. My mediaserver is keeping the phone awake for almost an hour+ each day, and without root I can't figure out how to stop it. I always have GPS/Google Now/Bluetooth off, too.

I thought the drain was related to Wifi. But last night WiFi was turned off for the night and I still got 18% battery drain in about 8 hours.

Wifi at home and overnight. I get about 5% drain... however, the wifi at work kills my phones battery with the wlan wakelock.
Maybe there is something going on with the X and certain wifi networks?

Interesting theory but my overnight idle drain was approximately the same on both LTE and WiFi. 10-15%.

How about turning off all radios (flight mode) and observe battery drain at night. Then turning wifi while on flight mode the next night and see the battery drain and so on until you can pin point what causes the most drain.

[Q] msm_hsic_host wakelock

I'm getting a regular wakelock labeled msm_hsic_host. I thought this was related to the phone's radio, but I turned on airplane mode and the wakelock continues. Anyone know why?

You probably have a rogue app polling for a radio signal and putting it in airplane mode is making it worse.

The same wakelock doubled my battery drain last night. I had it in airplane mode overnight. Going to leave the signal on tonight and see what happens. I was getting between 3-7% but it was 15% last night.

Tested it again last night. Unplugged at 4pm yesterday and used 5% battery overnight. I just hit 24 hours with light/medium use today and battery is at 75%. I know others have shared this but battery life has certainly improved with time. The wakelock is certainly reduced leaving data connected overnight. Hope this helps.

GSam battery monitor has an option at the bottom that looks like a vacuum. Its called app sucker. Once that screen opens there is a drop down menu at the top that allows you to see the kernel wakelocks. Then you can select each wakelock and the next screen has a button there to google it. Hope this helps.

Looks like it's a big problem for alot more phones. I have the same wake lock also. I get about 1% per hour by leaving it overnight. Is that normal?

I think it is. But alot depends on your settings and the strength of the cell connection. Actually the cell connection is about the biggest battery drain that I have. I use Tasker on my phone. It disconnects my cell connection when the screen times out and limits anything running in the background. Calls and texts still come through. When the screen wakes up everything reconnects. Some would say the settings I use are extreme but I get good battery life from it. Tasker can be difficult to start at first but there are some good youtube how-to videos. Im hoping the new battery saving feature in lollipop will make it unnecessary to regulate any settings. I guess we will see.

This. I use tasker to turn off data and auto sync when I go to sleep (because its literally a waste of battery) and I got 0% to 2% drainage overnight (total, not hourly) but that was with a custom rom. I expect 0.5% to less than 1% per hour with this phone because at idle with 4g on I drain about 1%/hr

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Sony Xperia Z5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Battery drain rating on Sony's Stock ROM is only average (0.7-1% per hour in Airplane Mode), no matter if (unrooted) Stock ROM or with Custom Kernel; 0.5% at best with gauge tweaks and other modifications;
AOSP/CM ROM appears to be excellent - 1% per several hours;
doesn't come close to my Note 3 (a few per cents per day) or even my Galaxy S1 with the original battery (2-3% per day), but that's no disadvantage of the Z5 per se
battery's technology simply wasn't allowed to catch up with progress yet

Something keeps my device awaken - not sure what this could be, as the Wakelock Detector and other apps that can show culprits require root to run on Android versions from KitKat and above. This causes battery drain when the phone is not in use overnight. Does anyone else have similiar issue?

it's most likely something else
or part of the kernel or deep within the system,
because blocking wakelocks does hardly have any effect

I find my standby drain to be terrible. I can leave my phone in my pocket, with all background app closed down and it still somehow looses 30% in about an hour.

You keep breathing while sleeping

I use GSAM Battery Monitor to keep an eye on things. After a few weeks I'm happy enough with battery drain levels.
It mostly depends on phone signal; if I'm at home the signal is very weak and this can drive the standby drain up to nearly 10% an hour, and the phone can get warm. But if it has better phone signal then the drain can be as low as 2% or 3% per hour.
I have my phone set to turn off wifi when screen is off. I also use a Notification area weather app, Messenger, WhatsApp, Facebook, Instagram, etc and I have a number of email accounts and calendars syncing regularly so I would say I'm not running things in a lean manner. I'm sure if I uninstalled most of these apps my standby time would be spectacular, but then I wouldn't be getting particularly good use out of my smartphone.

Have you tried with BREVENT APP together with an aggresive Doze app (Greenify, ForceDoze, NaptimeX)? I´ve now installed Brevent + Greenify and standby during night from 100% "only" takes me 0,5% per hour more or less.
Also inside Brevent you have possibility to access to AppOps (be careful with this option).

I found that Bluetooth was causing massive drain on my phone. The fix which worked for me without turning off bluetooth (I like it to auto connect when I get in the car) was Settings->Location, then click the 3 dots menu in the top right and then Scanning, turn off Bluetooth Scanning. There are a few other things you can do as well.

put your wife to sleep
wifi, advanced options, keep wi-fi on during sleep, and select never
ever since i have done this, i am doing a bit better on the battery front
also, went to dark wallpaper. that helped a bit to.

First, before taking any actions you should install a battery monitoring app and one for data monitoring.
After several days, analyze them to see if there is any app working and transferring data constantly around the clock.
Also, try to reduce the number of apps working (or updating) in background. For example email fetching (switch it to manually instead of auto fetching every x minutes).

I used gsam battery monitor but nothing seems to drain my battery. I could barely reach 2 or 3 hours screen on time
