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!

Help with Battery Life

Hi guys, I'm worried about the battery life of my HTC One.
When the phone is on lock mode, meaning screen is off, within one hour battery can go down from 1-3%. Power saver is on, brightness is auto. And 4G/LTE is on.
Also, I only play around with my settings, checking out GSAM battery monitor, within 15 minutes battery can go down 1-2%.
Now it's been 6 hours 22 minutes since I unplugged from charger, battery level is 74%.
Is it normal?
Thanks.

Gsam should be able to tell you where your battery is being used and what app. Look at what the offending app is (most likely Google maps and Google+ or facebook) and use an app like greenify to hibernate them when not in use.

You do realize that the phone is still doing stuff when the screen is off, yes? Syncing e-mails/facebook/news stories, communicating the the network, etc. Even if the phone were completely off, lithium-ion batteries will still deplete(albeit very, very slowly) over time. 1-3% loss in an hour is pretty normal in standby. If you're really concerned about it, you can check out an app called BetterBatteryStats and it'll show you what's waking your phone up from sleep and/or preventing it from sleeping to help identify apps whos sync settings are too aggressive.
Your battery has depleted 26% in 6hrs 22minutes... you're losing roughly 4.08% per hour, at that rate it would take you ~24.5hrs to deplete the battery. Battery depletion is, can be, and should be accelerated when you're using the phone, so 1-2% within 15minutes while looking at a battery monitor... yeah. The more stuff you do with your phone, the sooner the battery will run out.
TL;DR: your battery life is fine.

It's going to be very difficult for you to replicate the results of someone else(and we are lacking a ton of information from that post--is he running a custom rom, custom kernel, are screen off/on profiles being used, what apps are syncing, how often, how many, etc).
Beyond usage, phones can vary greatly from within the same model based on the manufacturing process/location/materials. For instance, there's a thread in the General Section exploring the differences in various HTC One's screen maximum screen brightness. Even down the chemistry of the batteries themselves. I know from personal experience that one of the biggest impacts on battery life can be how strong of a signal you're receiving from your carrier. If you life/work in a low signal area, the phone will increase power to the antennae to maintain the connection whereas if you're in a good signal area, it doesn't have to work as hard.

Anyone use GSAM Battery Monitor app? Why does the battery usage % doesn't add up to 100% when you add it with the remaining battery % sometime?
Yesterday it's still fine. But today my battery usage % + remaining battery % only add up to 93%.

Most people use that app. I'm not sure why it isn't working 100%. Did you plug your phone in for a very short amount of time? That might make errors. After you charge it overnight everything should be fine. Try using it for another day.

In GSAM Battery Monitor, my App Usage is always the highest contributor to battery usage, usually around 85%-90%. Screen is only 10.8%.
When I dig deeper into the App Usage, Kernel (Android OS) 23.8%, and Android System 15.7% are the top 2.
Is it normal?

Btw, do you know what is AsyncCollectorListener wakelocks that come from Maps? It also contributes to high partial wakelocks percentage most of the time.

Battery drain when idle?

What type of drain are people getting while phone is not in use?
Last night I dropped from 64% to 54% in 9 hours, despite the fact that better battery stats showed 97% deep sleep for the time period. Seems bad to me. On lots of other phones, overnight drain is in the 2 - 5% range.
Yes, active notifications are disabled while I sleep. I don't even have touchless control set up yet, so it can't be that. I have the same few location services turned on that I always do, and like I said, I usually see 2-5% overnight on other phones, not 10%.
Anybody else?
PS for those of you who want to say who cares, I did this test because I was noticing faster than usual idle drain during the day, too, but sleeping is the best time to get a long chuck of idle time.
Edit: could it be because the phone always has those sensors on waiting to to see if the phone moves to light up the time? Or the double twist for camera sensor always being on?

Get "Better battery stats" or a similar app to see what is running during idle. But to be fair that is just over 1% an hour.....that is not awful whatsoever. The only way you could get any better would be to disable any wifi/data, and those location services.....OR just turn the phone off completely. I've had phones that have had way higher drain on idle than 1.5%.

[Q] Battery/Power issues / management?

I'll start this thread by saying that I've read up on all the battery related threads and visited all the ones suggested.
When I first got my Z3c (~January), I was getting 4+ hours of onscreen time and a good 12-15 hours of life from charge to charge..
Now I'm on Lollipop, and everything seems to have tanked dramatically. Granted I spend hours on my phone everyday, so maybe the battery isn't as stellar as it was (I charge it halfway through the day and it's still poor), but it seems to be giving me miserable performance.
When I go into the settings and check the power consumption menu, when the battery is about 90+% full, the basic screen tells me I have 14h of standby remaining, but if I go into battery use it only says 6 hours total (which is totally accurate) In fact, I'll drop from about 60% to 8% overnight while I am asleep, if I am not charging it.
When I check the App Usage submenu, nothing is listed. No apps at all, in the "Consuming Apps" or otherwise... I'm heavily considering downgrading to Kitkat to see if this helps, but is there anything else I can try first? I can't seem to locate if there's a sleep or wakelock issue.. (one thing I have discovered is that even when the screen is asleep, it still seems to emit a bit of light, like it's actively showing a black square)
I'm not rooted, but I do have the paid version of Greenify.. Suggestions?

You can get the Deep Sleep Info widget which will tell ypu whether your phone is reaching deep sleep when the screen is off. Here is the link: https://play.google.com/store/apps/...p+info&pcampaignid=APPU_1_0E-aVYj-Iob9Uqa3uyg

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.
