BATTERY LIFE: 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 Note5'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!

I'll test this later today. Charge my phone to 100%, and right before I close my eyes, I'll unplug and see how it does. I'm curious as well.

Typically 0.5% per hour or less with lots of bloatware disabled (200+ apps). Couple gmail accounts, s note and scrapbook syncing.

So I unplugged my phone when it reached 100% and got a notification saying the battery is fully charged and unplugged it at 10:40 pm. About 7 hrs and 20 mins later, my phone dropped to 93%. That's about 1% every hour. My phone is stock, no root (yet) with 17 apps disabled. WiFi is on, brightness was on the lowest setting and all accounts on my phone sync through the the night.
I've never done this with one of my previous phones, so I can't really give you my opinion on how I feel about this. Let me know what you guys think. I'll try disabling some more apps and doing the test again and see if that has some effect.

if you are rooted and have xposed. download Mobileactiveradiofix...bassically some apps you are using that utilize mobile data, after you turn off the screen it still using data....thats the gist of it.

Drain about 1% per hour.
Tried 3G all the way. Not much savings compared to LTE all day

I have the 920CD Dual sim. Horrible Battery standby. I lose 2 - 3% per hour on android system usage while i'm sleeping.
I tried disabling apps etc but to no avail!

During night my phone consumes up to 30% of battery, my stand-by is 16hrs at max!!!. I love my phone but there is an obvious problem about it.
On the other side my wife has the same phone and her battery withstands up to two(2!) days.
(Hers is running on stock firmware with simple tuning, mine is also on stock but i checked and disabled almost everything)
My phone is ; N920CXXU1AOH2 hers is N920CXXU1AOGF. Is there a way i clone her phone firmware and copy into mine?

I think you guys above may have Wakelock. Mine started up recently and it drains up to 15% of my battery from just a bit under 2 hours. Before that it would be fine. Unplugged all night (8hours) and lost 2-3% battery

I couldn't believe this rating was so low. This is the best at standby. Absolutely phenomenal. It's literally around 1-2% an hour. I can get home after 11hrs and still have 70% left. Usually it's around 50% with 2 hrs of screen on time / use.

Got an update yesterday. ..it includes the doze feature from marshmallow. ..vastly improved the standby time
ścribbled from my Note 5

I wouldn't call 1-2% per hour idle time phenomenal, It's average at best.
0.5% per hour (or 2 hours per 1%) I'd say that's very good.
3 hours per 1%, that's excellent. This happens to be my Xperia Z3 Compact's idle time when I sleep.
Phenomenal? It would need to be 4 hours per 1% idle time.
My Note 5 is doing 1% per hour currently.

My iPhone 6s Plus can go over 7 hours standby and still be at 100%. One of my biggest peeves with Android was battery drain. Just switched with the release of the 6s and am very happy. Had the Note 5 and still have the Nexus 6. The doze feature still can't even come close. And it only works if the phone is shelved. Not in the pocket. Not good enough for me.

Please everyone who has the drain, write samsung feedback on their support website. It is most of the time caused by the wlan_rx_wake, wlan_cntrl_wake and wlan_wake wakelocks. I am trying to find a fix but so far nothing has helped me except turning off wifi.

Really? I can live without WiFi most of the time if it helps my battery.
I was getting great battery life, I stopped using the Note 5 for about 3 weeks while I reviewed some other devices and when I return I'm loosing 5% an hour, doing nothing. I've done a factory reset once, slightly better, but still not great. Might try another tomorrow.
Let us know if you find a fix.

just like you .. I come from a s6 and did not have this problem, hopefully be resolved soon

During night, I switch off mobile network and wifi, but both SIM still active for phonecalls. Drain this way is around 0.5% per hour or 3%-4% per night - depending on how long I sleep

Frankly, I only used the phone with the latest update so, I have no idea about battery performance before it. Anyways, I'm getting great overnight battery performance, with 3% dropping in 7-8 hours (mobile data, wifi and bluetooth off).

all data and BT off and you're dropping 3%? Turn your phone off and you'll drop 0%

Mediaserver, system and kernel kill my standby. Is it worth factory reset or should I hang out for marshmallow?

Battery overnight

7% of battery overnight.
Wifi, 3G, google now and side clock on.
Is this normal?
Standby Cell=2% (5h on time)
Android OS =1% (13m cpu)
Standby Device = 1% (4m cpu, 28m active)

I too loose between 5-7% overnight (8 Hours). Although the battery life of Edge+ is pretty good while in use, I have noticed that standby of the device isn't as impressive as earlier Note variants (Yes, I'm comparing with Note series).
WiFi - ON
Auto Sync - ON
2-3 Apps with Notification ON
Samsung Pay on Screen Off - ON

Your CPU seems to be idle 95% of the time! I never checked mine but yes, mine drops that much too! I don't think that's a rare case with this phone!

Ok so it is good right?
Then why it drains so much overnight?

Depinding on my signal strenght ,i saw -10% overnight ,ok maybe i slept like 10 hrs insted of 7-8 but still . Battery info said that the juice went to Cell signal standby or something like that.

yep, same here... so maybe it depends on the strength and quality of cell signal..
will test in the next days...
I am sure it cannot be any samsung app/service as I have disable 200 of them with package disabler pro
also, location/3g/wifi/sync/googlenow always on is the same setup I had on OnePlus One, that was using barely .5% per hour
it also true that on the OnePlusOne I could also turn off the notification light during night, while with this I cannot so it could happen that the light keeps on flashing for 5 hours, draining battery
also, I have edge clock on at night, still some drining...

I thought the deep sleep or idle drain was caused by lollipop, no? I lose over 10% from a 7hr sleep, even if I turn the WiFi off. WiFi eats up a lot of my battery for some reason, and I know my connection was good too.

It's been 5 nights and I confirm it drains 1% per hour.

This is my usage really bad...
8% in 6h
Night clock on
Wi-Fi on
4G on
Sync on
I received 5 emails so notification light has been blinking for almost 5h
Don't understand, cos stats are not that bad...

Think yourself lucky. I'm losing 50% overnight.
Battery life impressive during the day though

I solved my problem: night watch...
With night watch on I lose 1% per hour at night, with night watch off I lose 2% in 6h

I was consistently losing 2%-3% per hour overnight. But once I found an overactive app (Plume) and changed from instant notifications to 30 minute polling, my battery life has drastically improved. I've also used Package Disabler to disable bloatware on my device.
The past couple days my battery has been around 97% - 98% when I wake up in the morning.

With Wifi on and Blue Tooth on, was very decent. Averaging around .42% (30.9mA) or less per hour, and last night I think I really did well at only 2% decline over a 12 hour period.
I'd say battery drain is fairly good on this device.

On airplane mode there is virtually zero battery drain. It doesn't lose any % over the night

First time I bought Tab S4 for my wife (64GB version) I turned on Airplane mode then turned on the WiFi + connecting it to my home WiFi.
It stay on standby for 10 days straight & when I checked it still have 50% battery.
I didn't test my Tab S4 256GB version though.

Mine is just draining like crazy even when I am not using it. I've had the tablet for 7 months now, and battery started to drain while unused last week. Let's say I have 100% charge when going to sleep and wake up with 60% of charge remaining. Before, I would drop only to 98 to 97% percent. Anyone with this issue? Anyone solved it? Shall I return the tablet?

Well first off.... I don't think you can return a tablet after 7 months of use.
Second, you said it started recently. What new applications have you placed on it? Updates to applications included. If you have something that monitors the battery drain per application that would be helpful. Since its new you could upgrade your tablet to the new Pie update might help out.
Personally I have had nothing but great luck on my tablet.

I've got the same problem. Brand new S4 LTE on ATT. sitting in my bag, unused, its draining 5% an hour. So I enabled Airplane Mode to cut the Mobile Connections and BT then enabled Wifi Only. Overnight I lost 20%. I'm going to run a new test: Charge to 100% then let it sit for 24 hours in WiFi only and see what happens. I may give a factory reset and set it up completely from scratch to see what happens. If it continues, I'll sell it and Get a Huawei MediaPad M5 Pro. My last 3 phones have been Huaweis and I love them. I like the UI on them and adaptive Power saving is stunning. And Huawei has the in my opinion the email and calendar app. They are linked and I can turn emails into calendar appointments. Thought I was going to Love this S4, so far I only like it and the battery issue is really irritating me. And mine weighs in at 516grams to a claimed 483 ....

No probs here, best tablet ever even comparing to iPad.

my tab S4 is 3 month old and it will only do 5 hours web surfing on wifi. previously it used to last for more than 10 hours. I tried to factory reset, it didn't work. then, I tried updating to pie and it didn't work either. any suggestions

One week of standby use all the battery (with wifi on), it's normal or I have some drain?
Tapatalked with A8 2018

I have the same problem, no clue how to fix this. I'm looking for a good iPad deal now...
Made an BetterBatteryStats Dump but this shows no problems: https://forum.xda-developers.com/showpost.php?p=80827125&postcount=36696

A few days ago I had battery drain too. It was related to Samsung Internet. Uninstalled and reinstalled it and the drain went away.

I'm getting some drain from time to time and the cause seems to be the smart scan (Iris+ face unlock), sometimes it crashes and the processes are stuck running constantly in the background.
The kernel wakelocks according to Betterbatterystats are "video6" and "video5"
And the process that is running in the background is "[email protected]"
A restart solves this drain but eventually it'll come back.

I also had the drain issue after the pie update. I installed WiFi automatic after realizing the drain seemed to be related to no option to allow WiFi to turn off when tablet asleep. I have now set it to turn off 2 minutes after screen off. Just went 20 hours of standby losing only 2%.

I also have a standby drain issue, but it even persists when the tab s4 is powered off. I was away for about 26 hours and I charged the tablet and turned it off before I left. I also unplugged it. When I got back, it was down to 49 percent, after sitting off for 26 hours. I'm not sure what's causing it. It's only been happening for a few weeks or so. It also happens when the tablet is on but in sleep mode.
Battery life in general seems to be worse overall.

Please understand that this device is just released and OS is not fully optimised yet. I'm sure oneplus will address the issues with upcoming updates. You're previous device must have gone through lot of updates to fully eliminate the bugs to achieve those results

Hmm it's not that simple ... Some updates as the one for my previews phone that did that 1% of draining passes through newer phones... As you've noticed my phone was Nexus 6p from 2015 realeased date and the other guy mentioned the same thing for the pixel 2xl whose realeased date was two years later. So having been said that thing, it means older phones of OnePlus have the same behavior or probably worse than the 7 but any has as good as Google phones for example. I hope they will fix it as you've said though

Getting 2% drain overnight, rather consistently. WiFi on, BT/4G off. On newest OS version 9.5.5

Mine drained 3% after 8 hours of standby 4G volte is on WiFi on and everything else is switched off.. coming from s8 plus i consider this as a great standby [emoji28], usually my s8 plus will drain around 5 to 7% after 8 hrs of standby

Never tested how much standby drain I get at night but compared to the Mi9 it's much better!

Don't know what's happening, but I'm losing more than 30-35% from 3-4 days. Phone's not rooted, so I'm having tough time to find culprit.

Same setting on OP7, overnight drop 8% at latest, even already enabling battery saver mode, only installing 14 apps, a little bit disappointing.

4% within 7h44m = 0.5%/h:good: overnight with dual sim mobile network enabled, wifi off.

I had like 3% drop on 4.30hrs overnight. Usually sleep at 1.00AM and wake up at 5.30AM, went on 79%, woke up on 76%. Dual sim on, Wifi On. mobile data bluetooth and all other connectivity settings are turned off.

I still get 7% of drain overnight. It doesn't get any better.
Today I left the wifi on and drained 13%.

No drain, sleeps like a baby. Around 0.5% drain

Standby drain is quite a lot worse than on my OP6 tbh. During night I lose 5% vs. 2% on my OP6. I also lose more during the day in standby. In 15 hours time I lost 40% with just only 2 hours SOT. No culprit in battery graph.

My standby at night is HORRIBLE. It was amazing on my 6T with only a few percent lost at night (6-7 hours). My 7T doesn't seem to go in to any sort of standby. It pretty much straight line drains the whole day with no distinction for night.
With my 6T I was often able to go 48 hours between charges with moderate usage. This one mows through battery at night.

Mine drains by about 5% overnight and i leave network, Bluetooth and WiFi on and i have also turned off Sleep Standby Optimisation to make sure any calls or alerts get though due to having elderly parents.

Same experience, although my battery drain during the night isn't that bad (5%), but still not good. My issue is mainly idle drain during the day.
Been at work past 12 hours. Lost 25%, and I barely used the phone (maybe 20min). This wasn't the case with my OP6. Weird.

I lost 20% from 12:15 am to 7:30 am. It was at 33% when I put it down and 13% when I got up. I cleared out all recent apps before turning off the screen and going to bed.

I don't know how long you've had it, but I've noticed that the battery is significantly better after a week or two.. I think it's something with android 10. Right now I'm at 10hrs since charge. 1h 15m use. I've lost only 10%.
Last week it was the double.
