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!

Massive Battery Drainage Overnight.. Please Help

I lost 26% of my battery in around 6 hours last night while i was asleep. Never had such a problem. Didnt install any new softwares and Gsam showing that it was awake for only 8 minutes. Wakelock Detector also didnt show any unusual wakelocks. Have no idea what went wrong. Have a non rooted phone. Had my wifi on the whole night (but that is on every night when am at home). And even after restarting my phone, i was yet having the high drainage. I suppose that my phone is just not going into deep sleep for some reason.

Android System or HTC Sense taking a lot of battery usage? That's what I'm getting. 6-10 hours even on idle.

Cause google now!

I think the problem only seems to happen when i am on wifi. Not sure though.

WiFi does tend to drain a lot of battery. I recommend turning it off when you don't need it. Such as when you aren't near an WiFi access point or in this case are asleep.

3%+ per hour drain on idle--how to detect problem app?

So my first Note 8 had draining problems which seemed to somehow fix itself with every other cycle. I replaced it with my current Note 8, which had really great battery life for a week. Yesterday, it started draining randomly at 3%++ on idle. I didn't download any new apps. I didn't change anything at all. According to GSAM, it just says it's from app usage, but I'm not using the phone and all apps are closed.

In Settings|Device Maintenance, you can find a list of apps that are draining the battery.
What does GSAM report for deep-sleep percentage?

Do you have AOD turned on? Many are reporting excessive battery drain from it.
I have found this useful on more than one occasion. It will give you deeper insight into what's going on, than the battery monitor in the phone.
https://www.xda-developers.com/stop-wakelocks-android-without-root/

Another vote to look at disabling AOD.
I checked my battery stats yesterday and it was the top consumer after 5 hours of work. I didn't use my phone much - there was about an hour of SOT, but the AOD seems to be taking way more than 1% an hour - more like 4-5% an hour in my case.

I do hope that they fix this issue in an update. I'd like to use AOD, but not at the expense of that much battery life per hour. I guess when they're testing their software, they don't test battery drain.

I wonder why the AOD draining more. I don't ever remember seeing AOD using battery on my S7E. I love the AOD but i have it set on a schedule. ifi leave it on all day it consumes 5-6% battery.

Chiming in to say AOD was the culprit for me as well. I was losing as much as 5% an hour on AOD. Just not optimized. I had it on all the time using my S8+ and it didn't drain more than 6% for a whole day which is something I can live with.

I don't have AoD turned on, but it's also not disabled. It's still active, but I can disable it with BK Disabler.

It doesn't list anything in particular that is draining it, which is why I'm having so much trouble finding out the issue. My old Note 8 would drain for 3% per hour and then after a charge or two, it would go back to normal. This time, it hasn't reverted back to normal yet.
For deep sleep and light sleep, they're both around 40-something percent.

Mi A2 suddenly doesn't Deep Sleep as much as it used to, any way to diagnose it?

I'm still on 8.1, for information.
So usually, according to AccuBattery, my Mi A2 stays in Deep Sleep for ~98% of the screen-off time, which gives me a nice battery drain rate of about 0.5% per hour.
However, a couple of days ago I've noticed higher battery drain while idle. I've checked the stats, and AccuBattery tells me that my phone only sleeps for 85-92% of the time, which surprisingly increases the battery drain considerably.
Question is - is there any way to find out what exactly keeps it from Deep Sleep? Because it certainly does still go into it, but not as much as it used to. I didn't install any new apps or system updates(still using the stock 8.1, as I've said) for a while, so I'm really not sure what could be causing that.

That is why we have Greenify for.

Nah, I've actually used that before, and while it seemed to help at the time, right now it doesn't. I've actually uninstalled it for the time being just to see how it goes.
Right now, I've checked my stats through Battery Historian and it seems like radios are at least one of the reasons for the wakelocks. Right now I'm on airplane mode and the drain is at a respectable 0.6% per hour. However, it still only deep sleeps for 93% of the time, while in the past it was 98, so apparently it's also something else.
Another thing that apparently wakes my device a fair bit is ANDROID_SYSTEM : deviceidle_maint. But I've no idea what to do about it and whether or not it's normal or expected.

Question [Help] SOT

It is my second day with the phone. Exyons version. I charged it 100% and left home at 5pm and here were are 11:40 pm 21% with 2hours 44 mins SOT
How?
4g enabled about 40 mins
I only used camera, google maps, a little facebook and uber.
Bluetooth enabled for the watch and the buds.
No wifi. No nfs.
Adaptive refresh rate and 1080p resolution after it dropped to 60%.
What have I done wrong?

This is very similar to my situation but I have snapdragon version my SOT is not that good get about 2-3 hours with 8 hours of use. I already resetting my phone once I'm currently still going through the learning usage pattern after my reset. Hopefully it improves because I'm hoping that my phone is not defective.

I thought about resting the phone but I have already downloaded about 20gb of games :/
I will wait couple days to see maybe the phone is still learning usage pattern . Please keep us updated if SOT got improved with you

I sincerely advise you to do a factory reset, don't restore any data (except stuff like picture and video) and start again installing apps, don't install everything, just the necessary and check the battery, you will see a big improvement.
start from there and then look at the difference.
different apps can behave differently.
And of course put anything you don't constantly use to deep sleep in battery setting!
I did it and my battery now is totally fine.

Question for you. What is normal battery draining for you. For example, if you leave your phone over night usually how much percent does your phone drop. And how long does it take your phone to drop by 1% obviously this last question depends on what app you're using but ideally on average how long does it take your phone to drop by 1%. The reason I'm asking is Because I kind of want to gage how my phone Is performing compared to others. Thanks!

Yea what's been said above, don't use smart switch and give it about a week to settle in, you will genuinely see an improvement.
Put all apps you don't use regularly/ need notifications from in deep sleep. If you have crap signal at home turn on WiFi calling. Turn off nearby decide scanning in connections.
If you're still struggling after a week, download GSAM as it gives much more detailed stats
I lose around 0.5% an hour overnight on standby

on average I lose 0,6-0,7%/h when the screen is off and an average of 10%/h when the screen is on.
fhd+, bt with smartwatch, location off, mostly on wi-fi (when I'm on wifi I use a Bixby routine to turn off data and switch to 2g but I don't think it makes much difference), lots of apps to deep sleep but not apps like whatsapp telegram and gmail.
anyway, everything depends on your specific use and apps installed but I can say my battery life was half than now when I restored my settings and apps data using samsung stuff.

Thank you. I will do a factory reset and update you guys later

I heard that uwb application is the culprit. Many users reported worst battery life with it. It's something related to 5g ultra wide band. Hopefully future update fixes it. Check below thread on how you can remove it. Not sure what functionality gets impacted by removing it
What is Uwb Application and how do I stop it??
So this morning I noticed this app I've never seen before, Uwb Application hogged 14%. I've never seen it before. What does it do and how do I stop it? I recently installed microg and YouTube vanced? Does this have anything to do with these apps...

FHD+/120hz/5g off/smart things off/ everything else normal
Overnight loss is about 2-3%
From 100% to 99% withing 3 minutes after wake up in the morning. That's turning screen on checking Facebook, or browse news.
My Huawei P30 pro would go 99% probably after 30 or 40 min of morning browsing
iPhone 12 pro max I am testing now, stays 100% for about an hour fr a wake up, that's browsing internet social networks

To measure battery loss from 100-99 is meaningless. The last several generations of the iPhone have behaved like this but clearly this has no real meaning, Which is more accurate? From that clearly the Samsung is the "least worse". To stay at 100% for an hour is absurd. BS calibration. Similar for the P30 Pro. Overnight loss of 2-3% is par for the course (I lose -using GSAM Pro - 0.6% per hour overnight which is probably very similar to you) So ignore a 1% drop in 3 minutes. It is just a matter of calibration.
Edit - added per hour re the 0.6% to clarify.

iOS is lying about battery percentage. If you see 100% it's in 100-95% range.
Anyway, it has more efficient deep sleep.

Yeah. Shouldn't the battery only be at 100 while it's plugged in? Cause as soon as you unplug it, it's obviously using the battery juice...which means it's no longer at 100.

I'm not sure if these Temps and cpu usage are normal, which I don't feel like it's normal, but every time I pick up my phone My phone is just running at 100% cpu usage. Granted I already reset my phone two days ago and got two full charges in. And my battery says it's still learning usage pattern. I'm not sure if this is part of the learning usage pattern phase.
