[Q] Battery drain when idle

Hey guys,
Wanted to know what your experiences with battery life were like.
When I go to sleep, I switch off wifi, bluetooth and data. When I woke up after 8 hours, the phone had lost 7%. Seems to be quite a high number for it being dormant.
In battery settings, the 'Phone Idle' option was top of the list for battery drain.
Anyone else experience battery drain here? What have you done to help improve it?
Cheers.

What's your reception like?

Install better battery stats or some wakelock app and see what's keeping your phone awake

Don't you need root to use better battery stats? Phone hasn't been rooted yet.
Signal strength is decent, not full bars, but close to it.
My last 2 phones (N5 and OPO) have had really good drain whilst dormant, so puzzling as to why this one is playing up!

My vzw was similar. About 10 hours of no use and was down to single digits.
Did a factory reset and it was better... Teach it who's boss...

Last night my phone was off the charger, at 100% to begin with, at around 2 am. I checked it at 6 am and I was still at 100%. For me, idle power usage has been very low.

Ya you need root. Goto WiFi settings then advanced and see if the 2nd option is on, (its something like apps scan for network even if its off) turn that off. If you want to stop Google play services from waking phone from privacy guard that helps a lot too.

Thanks guys. I will try give it a factory reset tonight to see how it goes. Will provide feedback once I've done this.

The other thing I did (not sure if it is related) was to disable all the VZW apps and processes. WHen I did that I only lost 13% when left over night and I was down to a respectable 73% after a full day of work (though I intentionally did not use my phone much during that time)

This phone sleeps unbelievably well, better than any other phone I've owned. It flatlines very nicely

I did not manage to factory reset the phone overnight, but I did notice that the battery life whilst sleeping was incredible.
Over an 8 hour sleep, I had dropped 2% battery life. I switch data and wifi off when I go to bed. Now I'll keep an eye on SOT. Hoping to hit the 4hr mark. On my first few days, I got 2.5 hrs.

Even I Am experiencing same problem. Any one plz help

I have the International H815 and I have the same problem. Battery drains too much on idle. When I look the battery stats the Doze mode rarely kick ins. Location is off Bluetooth off and I'm on wifi. When Doze works I have really good battery and I can hit 4h of SoT when not I can barely hit 2.5h of SoT. This must be some kind of bug. Phone does not goes to sleep and Doze rarely kicks in.

Really strange battery drain

Hello there,
I've a new G4 since last friday and I'm experiencing a really strange battery drain.
Let's say I will charge my phone to 100% and than leave it idle, it will start discharging really slowly with all syncs active (for example last night it lost 2% in 8 hours). That's cool.
The problem is that as soon as I start using it again it will drain really fast, like 1% every 2 minutes. What is strange is that after start using it it will drain fast (1% every 10 minutes) even if i will let it idle again, so screen off and same operations as the 2% lost during 8h in the night.
At the moment I'm in Germany and I've experienced same drain ratio under good and bad cell signal and wifi. My model is H815. I'm not rooted so I cannot see good statistics in BBS.
I've already tried a factory reset.
Thanks everyone fo the help

I would start with checking the battery information inside settings. In there it will give the biggest battery drains. If you're lucky, you'll see something else up top that is not Android System, Android OS, or the screen.

Try disabled sync while using others app to see the outcome

I have the same problem. That's why I have a spare battery + charging cradle + power bank. Maybe I'll need to flash again since my device is not acting normally.

Today it seems better, only stuff I've changed is that I've disabled the quick cirlce cover since I don't have it but I don't think is related. At the momento I'm at 50% after 7h of wich 2h and 15min of screen time. Seems good to me.
I will go on testing during the weekend and I will report back. I hope the culprits are not rocket player (and mediaserver sice my music is on the SD card) but I've noticed a higher battery drain when using it. (today I haven't that much)

Those are some very good stats so far. Poised to hit 4h on the dot for SoT which is considered the expected average

I had to use a different launcher rather than the stock one and also a quick circle app and that was it

It is, if you were to continue you would be looking at 12h+ of run time.

i think that is just reindexing of content on the sd card. It is temporary. It could also mean that your sd card is going bad and more reads were required.

I've tested the card and seems good, It's strange that is still indexing it, I've the phone since one week now.
The charge after the one that seemed ok was totally bad. I'll investigate more
Thanks everyone

If you add files or remove them then i think it triggers indexing. Leave it for a while it should go away after some time.
if it does not try a different card. I only use the red sandisk class 10 cards, these give the least problems.

This of course is way, way too long.
Usually this is because of a corrupt/unreadable/unknown file on the external SD. Copy all files to PC, format the card, restore files. The media scanner will now end it's process in a matter of minutes :good:

So I've investigated a bit during the past few days, those are the results:
- Media server is not anymore keeping the device awake that much
- It seems that RocketPalyer is using a lot of CPU compared to what it was doing on my Note 3.
- Battery drain still seems a bit random, yesterday for example i got 16 hours with 4h and 3min of screen time, today I'm already at 56% after 5h and only 1h and 20min of screen time (I'ìve not changed what I did with the device that much, and I'm under same network and wifi as yesterday at work)
I think that if I want to understand why sometimes is acting weird I will have to root and use wakelock detectors, btw now that I saw that the device is not faulty (I was able to get good battery time on some days) I'm not afraid that much anymore to root it.
Thanks everyone

I get 2.5 to 3 on work days.
I get spotty signal at my desk and the skytrain makes my phone go on a major drain

draining battery fast.

First two days I had the phone it had great battery. I was getting 16-18 hours of life with 4-6 sot. Now the last two days at work it's worse than my op2. By the time I got home yesterday I was at like 35%. Previous days I was well over 60.My android system is taking most of the blame. On my good days it was at like 8% when the phone would die. Right now with my phone at 79% it's already at the top with 5%. I've barely used the phone while I'm at work right now. It's been unplugged for 3 hours and my sot is 35 minutes. Not sure if it's got something to do with the ambient display. Maybe finger print scanner. Any one have ideas?

Seems like you had been on LTE for quite long. Mobile data takes pounding on battery life. You will always see android system, android os and Google services etc on battery stat when using mobile data. Not the same case with wifi.

same here
i have mixed net usage with m,mostly lte on and wifi
can anyone have its quick fix pls report asap
i have greenified many OPservices but it didnt helped

Not rooted yet. Didn't want to loose dash charge with a new rom but cat just chewed the cord so guess I'll make a jump. Is that only a rooted app?

Humm I thought it was the other way around. Nevertheless I have WiFi at work. Can't remember if I was on it though. I'll have to test that out.

You don't have to run a custom rom or loose dash charge cause your rooted. I'm still using stock oxygen 3.1.3,and have the basic functions like dash charge working. I'm not sure if you have to be rooted to use gsm, cause I'm always rooted, but it may gave you more specific insight as to what exactly is draining your battery quickly.

You know the image you attached, with the graph on it? Tap that and check the Awake heading. Is it one long solid blue bar? If yes: your phone stays awake (doesn't go in deep sleep mode). Does restarting it make a difference (i.e. does the solid blue bar get broken up)?
The problem emerged on my OP3 as well yesterday AND I had it on my prevous phone (a OPO). On the OPO the problem was that it wouldn't release a wakelock that kicked in during charging. While I haven't explored the problem on my new OP3 enough to know if this is the same problem, here's what fixed it for me if the problem is indeed charger related: when charged to your liking turn off your phone with the charging cable still in. Once turned off, remove the cable and restart the phone.

Are you talking about under history details? I'll check tonight once my phone is drained. I did a battery cycle yesterday. Let it die and charged to 100 while it was off. We'll see how it goes today. And your saying it was an actual charger problem?

Heavy battery drain might have to do with the "pocket problem". The fingerprint sensor constantly activates and is not properly blocked by the proximity sensor.
There are several threads and posts about it, here and on the oneplus forums...

Yea I had that once in a while with my op2 I'd take the phone out of my pocket and it would say too many attempts at the scanner. Nothing on this phone like that though. And of course today is a different story with the battery lol its good today. So maybe it's while I'm at work. Idk it's odd. I need some more testing. Currently I'm at 9.5 hours on battery with 56% left and almost 3 hours sot. I'll see how this week goes at work and see if I can diagnose anything

I've been having this problem as well, losing as much as up to 20% of battery overnight, while it was doing absolutely nothing. I've tried a couple of things, but last night it 'only' drained 5%, betterbatterystats reports 0.6% of drainage per hour.
I think this is due to the weather option in the launcher, could anyone else try turning it off and see if battery life improves significantly?

You don't even need to do that. You can just check it after an hour or even less. Just put the phone away for an hour with the screen off and check history details.

Not quite. I'm saying it was a wakelock that kicked in during charging and that wasn't released when I took the phone off the charger. I don't know if it was the charger caused the wakelock.

Great for two days now I'm leaving work with 45% battery and only an hour and a half sot. Unplugged for 9 hours. Idk I feel like it's hit or miss

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.

Question Standby time drain

I just came from S21 Ultra and I'm noticing a huge drain in my Fold 4 about 15% to 20% overnight and I'm not sure if it's normal nor where it comes from.
I disable AOD during the night. I used GSAM to try to figure out the culprit with no luck.
Do you have any thoughts?

I leave mine on a wireless charger overnight so not sure then, but it seems to barely drain anything through the day unless I'm actively using it. I did notice the first 2 or 3 days though it seemed to drain a lot faster while it was "learning" my habits. Now I have no fear of getting through a full day of heavy usage even though I've set the charging to cap at 85%.
A lot of things can affect it. 5G data takes a lot more power than wifi and I run wifi at both home and work so I'm rarely outside of a wifi range. I also use wifi calling. I don't use AOD except when there's a new notification.

I would speculate there is an app on yours not allowing deep sleep. Mine so far has only been dropping 3-4% through the night.

I just got it 3 days ago so hopefully I get your result.

I thought so at the beginning but looking in gsam I found out that combined app cpu is consuming a lot of juice. I'm a long time avid android user and I've looked into all the possible causes but surely I'm missing on something.
EDIT: battery drain while I'm using it is superb, but it drains while standing by.

I noticed with the Fold 3 it took a few days for things to settle and apps to sleep.
But def check what apps are NOT going to deep sleep. Then add those that don't need to run in the background.
I have the 3, waiting on my burgundy 4, and with very little use during the day I get good battery. At night, it would drop but not by 15-20%.

I guess it'll figure out how to last longer once it learns my behavior. I've installed battery guru to monitor things and hopefully catch the culprit.

I do recommend taking the time and settings the apps that don't need to run in the background to go to sleep. I don't need a calculator running, so it can sleep. And so on.
But yeah, you'll see things level out.

Be sure to report back whatever happens!

Sure, thanks.

I don't know if I've ever had a phone with better standby drain than the Fold 4. Just an experiment but I took it off the charger at 3PM yesterday and didn't touch it until 5:30AM this morning and it was at 95%. This is just the 3rd full day of use. I am using Nap Time with a couple adb commands to give the proper permission for an unrooted phone. Also turned of continuous scan for wifi and bluetooth, disabled Bixby and a lot of the bloat too.

Hi

Update: so I let it stand by and I guess the culprit is oneui home app and it's strange to me since it's drawing more than it should and keeps the device awake, and for some reason keeps the screen awake as well.
I've cleared the cache and force closed it and I'll see if this fixes the issue.

1% standby drain per hour on ANY smartphone is exceptionally good. Looks like you are 2.5% drain per hour. That's not terribly bad though either.
Try putting phone into flight mode before you go to sleep. This will tell you if drain is radio/app related or the core OS.

If its home, maybe a widget that's loaded doing polling not allowing deep sleep? Worth nuking them all see if it makes any difference.

What app are you using to check your battery stats?

Battery guru

I like battery guru so far. I use to use Better Battery Stats from here on XDA but it doesn't seem to work as well as it use to. I noticed that I have nothing logged for wake locks, is that a limitation on the Fold 4?

At this point, I give up.
My fold doesn't sleep at all even after a factory reset and wiping the cache, I can't figure out what is causing this issue. It's drawing anywhere from 5% to 10% per hour while standing by.

I advise you to install "gsam battery labs", and in the settings of this app enable "show more statistics" (this require a PC with adb minimal package installed, USB debugging on on the phone and a USB cable).
It can tell you which app uses what % of the battery and for what reasons (downloading, GPS usage, etc), even for system apps, and most importantly even when the screen is off or the phone is dozing.
This as been my go to app since using android phones, in combination with accubattery (which doesn't show system packages or anything usefull while screen off).
As for my ZF4, when the screens are off it is using 0.5% per hour during night time (deep sleep) and 0.9% during the day (light sleep)
