Battery drain over night

Hello, I'm new here. Coming from a Galaxy Nexus, and I'm impressed with this device already.
My question is if it's normal that battery drains around 4 or 5 % over night. I always turn off data, wifi, put it on airplane mode. I also disabled active display, the camera gesture thing and the voice commands.
I think it should be 0% drain :/

Zero drain is pretty much impossible unless you turn it off or own an old school Nokia

(Guessing 8 hours of sleep.) .5-.6 % per hour is great for this phone.
With data (not wifi), active display, gestures and voice commands turned on, plus a few root level changes like greenify, xposed amplify and freezing apps, I achieve around 1 % per hour at idle on stock 4.4.4. This usually equates to around 3 days standby and 1.5 hours of screen time for me.
(I am now testing lollipop... I'm at 1.5 days with 1.5 hours screen time, longer than normal talk time and 30% battery remaining.)

I don't even make it to a day lol. Usually I've to charge at night and then around 7 pm

Here is my sleep running r12 kernel. http://forum.xda-developers.com/showpost.php?p=59527748&postcount=811 And I don't turn on airplane mode or anything. That is just screen off.

Same problem here (Android 4.4.4, rooted).
Battery drain in flight mode (additionally also tried Moto Voice off, Active Display off, Data off, GPS off without any positive effects) is nearly the same as over the day when using the phone.
The fact that "Stand by" has 25% of all battery usage is a little bit perverted
I'm really happy with Moto X' battery consumption over the day. Normally I have to charge it every second night. But putting to flight mode at 56% when going to sleep and not charging it and finding it at 40% the next morning is kind of frustrating

Install Bettery Guru from Qualcomm, from play store if you run 4.4.x or download the apk from somewhere if you run 5.1+. It will help you reduce the standby drain.

Hmm...doesn't seem to do anything more that I and Tasker do: Deactivate WLAN, Data & Co.
But okay...I'll try that out

From my experience the Motorola SoC has a abnormal high Standby battery drain. You can try whatever you want but you will not get below a certain level like on other phones. Perhaps the contextual cores are never turned off no matter if you use the feature or not, i don't know. At least it gets me trough a day...

Not really, check the screenshot below. For 10hrs ide, it drained 2-3% witch is perfectly normal.

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.

I charge the phone 100%, tell me it going to last 12hours and go to sleep for ~7 hours and the battery is less than 30%.

Good very small drop while not being used, even when loaded up with apps.

I experience pretty bad battery drain on idle. Basically, if I leave my phone alone without turning on the screen, it would be fully drained in about 30 hours.
I've reset the phone many times but phone idle always remain as the top battery draining app. averaging about 100 mah per hour constantly.

Exactly this! My phone uses more battery while on standby than with the screen on watching things! I don't understand this behavior. Powernap + Greenify + Amplify doesn't solve it either, even the things that keep it "awake" are hibernated and also delayed by Amplify. Wakelock detector doesn't even detect any apps that are running during standby either. Also, I have no bad signal because it is always on full bars or 1 less than full.
If anyone figures it out I would love to know how to solve it.

I get this too. Im trying to debloat the rom of some apps that seem a little suspicious. Will do this tonight. Already backed up my current system partition in case I break something. Wish me luck! :good:

Tell us how it goes. I have actually converted the Amazon ROM to the OEM version, however, that doesn't fix the problem.

Me too. And I have debloted OEM rom to what I consider closest to slim or stock. We'll see later how it goes.

i've pretty much ran the Prime version debloated or the OEM debloated, same thing. I think it has to do with the phone radio and Android 6?
When I put it on airplane mode with only WIFI turned on, phone idle isn't as bad.

Maybe its kernel controlled? Have u tried flashing the 6.6 updates radio.img? Does it contain one? I only used prime to power on the phone from then on only OEM version debloated. And as you say its always consuming batt on idle. I'll give airplane mode a try today.

Alright, I have just installed the xposed module "MobileRadioActiveFix" so this will confirm if it is in fact the data that's impacting standby battery. However, not too sure because "Intelligent Battery Saving" does disable data over time and the draining is still happening in that mode.
Anyways, I'm going to be testing this and report back. @l33chpda @Alex_XV6700

I figured it out, I was monitoring the CPU states and the CPU is not using a hot plug. It nevers makes a core go offline even when the screen is off and it will ramp up while the screen is off because there doesn't seem to be a cap when the screen is off.
I think the only way that we are fixing this is if someone makes a kernel with a hot plug in it.

With Prime 6.4 mine lasts a month on Wi-Fi.

Yes, it doesn't make a difference. I do consistently get 4-6 hours for every two days, however, I can get more if the idle battery life is not there. For example, with your chart, my idle time would be about 45%-55% above the screen.

It's just the way it's reported in this ROM. Instead of looking at the battery stats, just look at the actual battery life of the phone, which is fine.

I have stock V12 vanilla ROM, and I find the standby drain can at times be worse than when I'm using the phone, and I'm not sure why. I'll put the phone in airplane mode and put it to sleep right after unplugging it from charging overnight and when I check on it in an hour or so it'll be down from 100% battery to 90%. When I turn off airplane mode and use the phone normally from that point on, battery drain is normal.

Yes, I experience the same thing! However, overnight, it drains about 10%-20% even though looking at the stats it is not even awake! It should only be draining about 1%-3% because it is not really doing anything at night.
Even the screen uses less power than the standby. @waingro808 could be possibly right that it is just reporting the battery stats different, however, on other phones with the phone idle, that percentage is very low and not as high as ours.

The battery stats dont add up either...
As you can see in my screenshots Im still 14% on battery
And it states that between SOT and Idle I have consumed more than the 2500mAh that this phone has on the battery.

From last 2 nights....i got 3 percent standby drain when I put my phn alone for 6 to 7 hrs with wifi on

Same here 3 percent over 8 hours at night. Seems like they fixed the drain problem of Wifi in comparison to Op5

Yes you are right
3 percent is almost negligible

10hrs standby with WiFi on, 4% (went from 97 to 93.) Pretty good I'd say.

3% as well no wifi

My device is draining battery little faster when using normally and on standby it is draining nearly 2% per minute while on 3g+ mode . Is it normal.. ?

Sorry guys .. It was a typo.. I meant hour. When I leave mobile internet on during standby I get 2% drain per hour when switched off drain is 1% per 2 hours. Location is off whole time.
So a H+ network drain battery faster compared to a WiFi ?

Location set to data saving, 4G data remains switched on as well along with WiFi

5% without wifi and data...I hope Oreo fix this...

how about when u guys use it until the end of the day while the phone screen is constantly turned on and off? 6h+ seems to be the average for sot but I haven't seen anyone post their idle times yet except for when it's during an overnight sleep

My friend has a 3t and his standby his pretty bad. He is on Oreo though....Does anyone else get a huge battery drain on their 5t?

My battery is draining as quick in standby mode as it is when I'm using it! I'm losing about 3.5% /hr over night. That is really my only complaint.
I'm leaving everything on. WiFi/data/ location/ Bluetooth.. shouldn't have to switch it off tbh.

If you live in an area that doesn't receive particularly great cell service, leave data and location off on your 5T. When your phone has to constantly search for a good cellular connection, it will eat power like a New Yorker eats a hamburger at a baseball game. And if a sub-optimal cellular connection in your area is the case, then 3% per hour isn't half bad...my Droid Turbo 2 would drain 11% in the same timeframe.
If this isn't the issue, then check the power consumption of the individual apps you have on your phone to filter out problem apps that may be draining your battery rapidly. If neither of these methods work, you may have to resort to factory resetting your phone, or RMAing if nothing fixes the issue.

So, I've narrowed it down to being a WiFi related issue. Something is running when WiFi is on which is preventing the phone from going into deep sleep properly (if at all).
When I switch WiFi off overnight, and leave everything else on (data/BT/NFC) then my drain goes from 3-4% / HR to around 3-4 % in 8 hours.
Can't figure out beyond that yet though.

I find the stand by drain right on par with my Note 10 Plus. It was fully charged at 7 PM last night and this morning at 6 AM was at 95%. I installed Nap Time by Francisco Franco with a couple of adb commands for the aggressive doze features.

Went to bed last night at 1am at 100% battery. No apps are running, i have a bixby routine that puts the phone into power saving mode while not in use over night. Woke up 7 hours later at 8am and the phone had gone down to 93%, so it has gone down 7% which is 1% percent every hour being lost. Looking at app usage nothing was running in the background this entire time. Had my device for 5 days now so has gone through learning stage. This is ridiculous standby drain, is anyone else having the same issue?

Yes my drain is also bad. Are you guys running Snapdragon or Exynos?
I am Exynos unfortunately.

Can any one try standby drain after installing naptime? Let us know if it helps reduce the drain.

I'm using Naptime and I think it does help with standby drain. it is in the par with note10 at around 6-7% over night.

I run it all the timed. Here's a screen of my settings, I don't disable BT on doze as I have my Note connected to my Panasonic home phone.

For me it was much worse, about 3% per hour during sleep! I just deactivated VoLTE calls (and also the 5G just in case) and it's much better all of a sudden! Can you try this, maybe it's the same problem for you?

Motion smoothness is the culprit
I have been playing around with Note 20 Ultra (T-mobile carrier locked version - SM-N986U)
I turned off 5G (Connections --> Mobile Networks --> Network Mode --> Switched to LTE/3G/2G (auto connect)
But even with 5G off my battery drained this morning while only have google maps open 10% in 45 minutes!
All my apps that I frequently use I have gone one by one under battery usage and selected put app to sleep.
My power mode was at optimized with so I lowered it to Medium Power saving and that looks like it took care of it.
If I go back to Optimized but keep motion smoothness at standard then the phone seems to handle battery usage much better (this is all with sync on for email push).
It much more on par with my previous Razer Phone and closer to iPhone XR territory.

Amazing. Only discharges about 0.5% per hour. Thats with always on display turned on.

My mistake on this. My Always On Display is set to tap to wake only.
However to get best battery life possible with Always On Display set to be on full-time, turn off auto brightness, then you can manually set the brightness down the lowest setting.
That might get you down to 0.75% per hour, but I haven't tested that myself on this phone. However with my S10+ I did that and it helped a lot. Only downfall is you can't see Always On Display in bright sunlight. However indoors is usually still visible.

Got the phone (n20u exynos) yesterday at around 7:45 pm. It had 64 percent battery. Did the phone setup, sync and played around with dex. The phone got warm. Went to sleep at around 11:30 and the battery lasted me till today morning 6:30, with 2 hours sot. Don't feel its that bad. I also think it might improve further as it is still in the learning phase.

i avg .9-1.0% a hour with screen off over night..

if you're having an issue with battery drainage, report it to Samsung directly via Samsung Members app.

Snapdragon. Switch off wifi and normal powersaving mode with 5g still on.
7hrs sleep time, consumes battery 4%

I'm losing 4 % each to Google and Youtube, though the apps aren't running. I've forced them to sleep when not being used and hoping that will slow the drain. I'll have to wait a couple of days to see if that has helped.

How do you know its 4%. i think its more. Also on a personal note Who uses Tinder bro? Get rid of that crap. Plenty better stuff out there. Not to offend everyone has their own taste, i just said it on a light note.
