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 Google Pixel's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

First night dropped 12% in 6 hours. Not impressed. But I gotta break in that battery.

I've been losing around 3 % to standby drain over my typical heavy 9 hour sleep (Rx induced)!
I've had mine since last Tuesday.
5" Pixel version.
Battery doesn't seem to go down unless I really get on device for a couple minutes.
Wheee!

Last night my pixel went down 2% over about 7.5 hrs so the standby time is pretty good.

My Pixel actually dozed for it's first night. We'll have to see if it keeps going. My N5x gave up dozing a long time ago.

The doze mode has been great for me so far. Standby time is better than any other android phone I've used.

From my other reply:
Battery has been pretty good for me so far. Seems to be settling in with optimization after a few days. Dropped 0% overnight last night which is awesome.
GSAM Monitor is saying my average is 19 hrs on, 4.5 hours of screen on time usage, 1-2 hours of screen off usage like phone calls, music.
EDIT: I also have pretty crappy signal at work.

Stand by time hasn't been a real problem for awhile. My Nexus 5 on KitKat and Lollipop(both before Doze) and only a 2,300mAh would only drop 2-3% over 8 hours. It's usage time that really matters.

Mine dropped about 10% the first night (Mon 24th), but I do live in an area that has poor reception. Have to place phone next to window just to get text and calls. If I go outside I may get LTE at 1 or 2 bars. Overall though battery hasn't been an issue and I love the rapid charging.

I'm "blessed" with an extremely good body clock, which means I wake up at 6.30 every day without any alarm... Even at the weekends

Yes ! Now a days u are lmao

doesn't the alarm still go off when it's turned off? my galaxy note 4 does that

Probably.

Using Accubattery to measure screen off battery drain I am typically between 75-85ma. Has anyone else measured their standby power consumption, curious what other values are as this seems high to me.
Edit: more info
Tested it overnight with and without bluetooth on, got it down to 40ma without bluetooth, averaged 70ma with bluetooth on overnight. Also got to test a Note 4 under the same conditions though without a SIM card. The Note 4 was using 11ma without bluetooth and 18ma with bluetooth on. Both phones connected to the same WIFI the whole time. May have to do a full reset on the Pixel as the standby power consumption is definitely out of hand.

Standby
My Google Pixel currently drains an excessive amount of battery even on standby, however thanks to quick charging its up and ready in 15 minutes. OS seems to be heavy usage of battery at the moment.

While I still think the Samsung will have slightly better standby drain, this isn't a good test. You cannot compare a phone with a cell signal to one without. The biggest battery drain on a phone is typically cell signal.
If you pulled the sim card out of the pixel and let the phones sit side by side overnight, that would be something.

I agree, this test is not a great comparison. The Note 4 did still have cell signal as they do connect to service without a sim card, but likely it is not the same as having proper service (LTE). I was trying to get the lowest draw possible on the Pixel and managed to average 29ma in airplane mode. This is the lowest I have got yet with the device which although is decently low draw is still abysmal considering that it had no apps running and no radios active. What is even more interesting to me is that google claims that the phone has 456 hours of standby time which suggests radios active (at least cell), unless my math is wrong this works out to a standby drain of 6ma which at least on my phone seems to be completely unattainable even with radios off.
I have looked around the forums but haven't seen anyone else posting power consumption information with the regular or XL pixel so I have no idea if this is unique to my phone or just standard with the Pixel. I haven't yet factory reset the phone but that would have been next, except that I am exchanging the device due to an unrelated issue. I guess I will see how the next one stacks up in this regard.

Thought I would post an update on my findings. After getting a new device and still having issues I have an answer and partial solution to my terrible standby drain. The culprit in my case is LTE. I am on FIDO in Canada which does use Band 4 though I am not certain if that is being used in my area. Anyways if I set my preferred network type to 3g my standby drain improves dramatically as the device idles around 10-15ma in my pocket and overnight is more like 6ma which is phenomenal. As soon as I set my network back to LTE my standby drain is 70-90ma and at best 40ma overnight if I'm lucky. My cell service for 3g and LTE are both good (green in battery stats). I know LTE requires more power however I would expect that power requirement to drop significantly when connected to WIFI networks which in my case doesnt seem to matter at all. At least now my battery life is awesome as others have reported. However connecting to 3g when away from home is a bummer and it's not really practical to manually change my preferred network every time I leave or enter a WIFI area. Looking at a way to automate this switch but on Android 5+ it seems that changing these settings via app are very locked down. I would also like to point out that my previous phones never seemed to suffer from this issue which only further makes me suspect that there is an unresolved underlying issue here (maybe related to the Band 4 issues being reported?). It sure is nice to open my battery stats window now and see some horizontal line segments instead of the linear march towards zero.

Hmmm, your s20 is showing amazing stats. It is not any particular app. I am sure device js taking time to seetle.
Are you on 120?
My screen on consumes too much 16% an hour.

After returning one handset to O2 thinking it was faulty because of the standby drain I got my 2nd one
A exynos chip S20.
After changing all the settings such as refresh rate, dark mode, disabled apps, sleep settings, always off, 5g ... It still drained something terrible.
I dropped from 100 to 77 percent in 1 hour, checking the battery stats there was no single app using it.
I did find that after a factory reset and manual install of apps (not smartswitch) it lasted a little longer but no way I'd get through a work day one one charge

Don't know what settings you have or what's wrong with yours, but I have the US Snapdragon S20+, and my battery is absolutely awesome, standby drain included. My settings are dark mode, hidden 96hz refresh rate, WiFi full-time (damn COVID19), optimized mode for battery, location and Bluetooth on full-time, no NFC on ever, and automatic brightness settings. Like I said, I've gone 2 full days on a charge before, but pretty much always get around 36hrs, with 9-10hrs of screen on time. I'm loving this phone ??

This is crazy figures! I don't get why Samsung are rpping Europeans off with the crappy exynos models. I have the exynos variant and need to turn aeroplane mode on overnight and get 0.4/hr drop.
Sot is usually about 8-9%/hr so from a full charge I should expect 9-10hrs SOT. I have had to fiddle with my settings a lot though.
Rubbish.

Do you guys have auto sync on? That affects battery but I don't know how bad it affects it.

Love to know how. Iv sacked off the device now. #worsehandsetever lol

That's issue with exynos have to do a lot of tinkering disabling apps and other stuff turning location and sync off and aod, ridiculous really, seems like snapdragon is top drawer straight out the box

I wonder how many people jumped into this thread to give a 1 star after owning the phone for less than a week. Give the phone time to learn your usage patterns, jesus christ.

dear all,
I managed to reduce the standby battery drain for Exynos.
Now if you don;t use the phone the battery won;t get consumed.
I am using Package Disabler Pro and some bloatware xml
i will create a thread here step by step how to.
cheers.

My S20+ Exynos drains about 0.3% overnight. Nothing special, wifi always on, sync on, 120 hz.
I had S10 SD version and it was draining 1.5-2% overnight on same settings

My s20 ultra exynos drains the same, ~2% overnight, but that is after ATD3 update

Always I am getting very bad results
I swithed off 5g and screen is running at 60htz
Battery drain on stand by is around 2% on wifi and around 4% if i use 4g data
Other thing that my phone is warm almost all the time.
I disabled many apps but with no improvment.

Question Horrible battery and slow charging on Pixel 6 Pro

I've had the phone for about 2 weeks. The battery life is horrible. I leave the phone charging over night and sometimes it stops charging all together. Last night I went to bed with 100% charge. Left phone laying on night stand. Woke up to 70% battery after 8 hours of doing nothing. Mobile network standby used 42% of my battery drain. What is going on with this phone? Should I get a warranty claim replacement?
edit: 11/30 Turning off Adaptive battery and Adaptive charging helped. However, still getting a replacement phone. I get no signal pretty much any where. Thought maybe it was because Tmobile network. After a few days of troubleshooting the phone and getting new sim card and esim, I literally get 1mbps downloads if any connection at all. On Pixel Reddit many others are saying their P6P is getting no data, seems to be a modem issue?

Check in the settings if "adaptive charging" is enabled. I believe it is by default.
This feature attempts to sync up your overnight charge with the time you wake up.
If it's miscalculating when you wake up, it might not be charging enough. It should eventually learn when you do wake, assuming it's the same time, etc.
But you can just switch it off completely and allow the phone to charge as it normally would.
As far as mobile network standby goes, I'm not sure. I've noticed in the past this is usually because little to no cell service, so the phone is trying very hard to find a signal (boosting more power to that internal module) and thus draining battery more. Do you have poor service where you sleep?

Factory reset and when ask to transfer data from another phone. Don't. You may have a rogue app.
I also have a high usage on "Mobile Network Service" but doesn't seem to affect my battery much. My overnights drain on my P6P are 5% max.

Battery charging is slow but my P6P has phenomenal battery. Set it up from scratch like I always do with a new phone.

Battery charging is definitely slower than my Galaxy Note20 Ultra, but I like the adaptive charging at night. If you set an alarm, it will trickle charge and reach 100% just before. This will prolong battery life but I think the standard charge could be a bit faster. 65W like OnePlus probably does more harm than good in the long run but a true 30W shouldn't be an issue.

the latest update doesnt fix battery drain... update ending 037... although the fingerprint sensor is better

Not another nitpick on the Pixel thread. My battery life is good, nothing lasts forever.

Did you check whether you use adaptive charging?
It's designed to let the phone fully charge ONLY shortly before you wake up (set wakeup timer).
I mean, it never properly worked for me, but maybe it does for you. Lol.

My Battery life is fantastic! I have adaptive battery on. When it's at it takes about 20 min of hard use to even move from 100 to 99. I have no idea why yours does that but I'm beginning to think these are trolls because so far my p6 pro is a powerhouse. Works amazing. I love this phone. Every other dam post is complaint after complaint. Even crappy phones on other forums don't get this kind of grief. Google probably over hyped the phone and people are annoyed that they had to wait to get one or it's a massive drive by Samsung to tone down the sales of Google.......Too bad Samsung won't just allow bootloader unlock to be easy and painless. Otherwise I wouldn't BE Loving my p6 pro.....

As others have pointed out, adaptive charging is supposed to slow the charging down so it hits 100% within the hour of your alarm to wake up. You can actually see it say adaptive charging on the always on display at the bottom of it's engaged. But not hitting 100% isn't what it's supposed to do. What charger are you using with it?

That's not actually a good thing unless each point takes the same amount of usage. This actually suggests that the battery level is poorly calibrated.

People here asked you many questions to find out of it's a user mistake/problem, or if the phone is the rootcause of the issue.
You answered not one single question (as of now).
So it's fair to assume that you are a troll.

I'll try turning off adaptive battery and charging. I read some saying the adaptive battery isn't working right even after days of "calibrating." And the adaptive charging is new to me, turning that off also to test for a couple days.
I have tmobile and the entire area from my home to work is covered in 5G. Was working great on my S20+ for a couple days until I got the Pixel 6 Pro. I went to tmobile store yesterday. They gave me a new SIM and checked their system. I'm literally about 1000 feet from a 5G tower. They showed me a calendar supposedly they've been working in the area and having intermittent service issues, doesn't explain why I get no signal all day.
I've factory reset the phone and didn't copy over anything from my old phone, seeing if that will help.

I remember talks back in the days when it was introduced (Android Pie, Pixel 3 I think) and already then people claimed to improve their battery life by "turning that **** off" - it would be a bit devastating to know that Google still hasn't fixed that.

Wow it has been that long since it was first introduced. Time flies. Just on day one right now and I'm already seeing more screen off drain. Will see how every turns out next week.

Return it.
May be a battery failure in progress.
While many Androids can be battery hogs until they sorted out, all should charge normally with a known good brick and cable.

Hi. I'm typing this answer form my new P6P as Google decided to replace my old device. I set up my phone from scratch without transfering anything from old device AND THE ISSUE IS STILL THERE. Insanely high network standby battery drain +25% of the whole capacity. This is nuts. The employee told me specifically that I won't have this problem with my new device. I don't know what to do. I think I'll just return it and to for a different phone. Btw my partner has a non-pro P6 and he has exactly the same issue. Our sim cards are vodafone.de. Lost count how many hours I was trying to fix this problem. What a time waster.

Question battery usage

hey there. ive had my p6p for only a few weeks. battery life has been poor since i got it, but worse since the march update. i noticed when i look in settings under battery and battery usage and then past 24 hours i see mobile network usage at 70%. i haven't left my house in over a week and ive been on wifi the whole time. isn't that weird that the mobile network would be in use so much? i looked under network and the sim and by default roaming was toggled on. i turned that off and switched my preferred network to lte instead of 5g. a day later, still not left the house and i see mobile network at 54%, still high. i haven't even made one call on this phone in days. im on t-mobile if that matters and seem to have good reception in my home. any ideas or settings i could look at? thanks for any replies.

Go to developer settings and disable "Mobile data always on" option, as well as you can disable the 2g always on for emergency calls from the wifi&network settings. That helped me.

Dont know whats wrong with my p6p. Was one of the users who had zero problems since december, switched then to 12.1 beta. Now im on QPR 1.1 and since QPR 1.0 my battery drains like crazy, and even with the slightest of usage while using 4G/wifi it gets way hotter then before and you can see the battery % falling like a waterfall. Checked ofc all the settings, nothing changed. All apps are the same, nothing new. With Dec Firmware i was at ~50% at the end of the day, now im below 10%.
Im a die hard android boy, but for me thats crazy how unstable the whole "system" is. You change nothing app/usage wise, and you just loose nearly 40% of battery capacity.

I personally hate the battery life on this phone. I charged it to 85% earlier and was texting a buddy of mine for a bit, and my phone was super warm for no reason and I lost like 20% just from that. It doesn't make much sense to me how the power is bad that if I do light tasks it just goes to crap. I hope the next phone is better.

Personally, forget the Mobile Network standby figure is just misleading.
On the original firmware mine said 3-7% and I would charge to 80% and then 24 hours later would have around 30% left. By the February release the standby figure was showing 40% but battery life exactly the same. With the March release it is ready 50%+ but again the battery life is still pretty much the same (couple of % more but that is because I moved to a dual sim setup).
Don't disagree that some are having battery issues, but don't go chasing the Mobile Standby number as it is likely a complete red herring and your issue is elsewhere.

yeah i noticed that too. Im no way focused on that % mobile standby. Im feeling the noticable higher temp on the device.

There are reports that the older 5G modem is at least part of the problem, so I would not dismiss it. The fact that so many disable 5G, 2G, or other mobile services and report better battery life is kind of telling, too.
I think that the March drop has improved my battery life a bit, however. Not great, but it lasts through the day.

My battery life has definitely decreased since updating to march build. My usage hasn't changed, but before, I went to bed with ~15% left, now I often need to recharge at ~22:00 whenever I want to use my phone before sleep. Temps also seem to be slightly worse. I sometimes notice the phone getting warm, which did not happen before.
On a plus side, I have no more connection problems at home since updating to March build (I can get SMS/calls again in my home office), so that's a trade-off I am ok with, even though I don't like it.

mobile network is definitely my problem. since i stay home most days, working from home and not needing to go out, i turned on airplane mode and then enabled wifi and bt. i get calls from wifi thru tmobile and suddenly my battery life is great. 24 hours after charging with light use i had 89% battery remaining. i believe overnight i had lost 1%. i plan on leaving it in airplane mode till i go out. i get my notifications and calls and have great battery life this way.

I've noticed a steep decline in my battery life as well since the March update. Mobile network appears to be the culprit. Verizon user here, on an old GUDP.

I find it sad we have to go through such hoops to get our battery life adequate enough for our standards, when it should be this way out of the box. I hope the next pixel phone improves upon this, and if it does even in the smallest way I'll be sure to trade my device in.

I found the "issue" for my drain/heat problem:
I discovered yesterday evening, that i was enlisted in the play service beta program. Opted out of it, cleared cache/data too. Figured then out, that my gpay cards went missing, added them back in 5 mins, no prob. Then i saw, that all my "battery setting per app" where on "optimized", not on restrict. Today i unplugged at 08.30 and till now after a 20min call and twitter/instagram usage, im still at 96% with absolutey NO HEAT!
Config:
Play Services 21.24.23
Carrier Services 98.0.435052141
Play Store 29.8.13-21[0]

Weirdly mine has noticeably got better, i am ending the day with 20 or 30% more battery left than i was before the march update.

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!

Great advice let's see what 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.

Great idea, I'll try and report back.

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)
