Question Did anyone notice the huge standby battery drain? Any way to measure what causes it?

[M4-NOOB]

First off, I love the phone and I'll keep it, but ever since I got the phone I've been wondering why it's draining so much in standby. It's my first Samsung phone since 2011, so naturally I assume it's Samsung apps/services that drain? Especially since I don't use any new apps than on my other phones and in the battery stats it doesn't really show any user apps that use a lot.



Anyone has way to measure what system/user apps drain during standby? Or even better, any dev that could do a deeper dive into this?

For example, I just lost 32% battery while sleeping for about 8h, it has never been this much on any other of my previous phones (OnePlus Nord/Pixel 3a/Pixel 3/Pixel 2).



In fact, my OnePlus Nord with 815mAh more than the Flip3 is currently on last charge 3 days ago (it doesn't show me hours anymore) and 2h35m SOT and 25% battery left. On the Flip I just now got 17h with 1h30m SOT and 5% left. Settings all similar besides location accuracy turned off for the Flip as that was a massive drain.

Something must be unintentionally draining the battery during standby and I really hope one of you smart guys can find it. Or Samsung fixes it with an update..

I disabled AOD and any unnecessary account sync processes. It's only drained about 2% in standby the last 5 hours, but there are still some things to finish configuring.

If have AOD on a schedule so it's turned off during sleeping, account syncing I don't have anything that I can turn off and I never did on any previous phone

How old is your device? You got to give it some time to settle. I had 15% battery drain the first night, after that it went down to 5%.

The first step in improving the battery is to remember that this isn't any other phone. You may want to explore what options are available and what all you have enabled. By default, almost everything is on to show off all the cool new features that make this a Flip 3, not a OnePlus Nord.

Got it 4 days ago

Which Flip features are in use during standby though? During standby it's just another phone

Not true. Samsung has a bunch of features still in use.

Settings -> Advanced features -> Motions and gestures has a whole collection of things that are still running when the screen is off (and most aren't useful to the Flip, but came from "another phone").

Settings -> Cover screen allows you to disable turning on the screen when notifications arrive, if that is not something you need.

Also, unless you are using the app to lower the refresh rate, you may be running a bit high when idle.

I've turned a few things off there, but a lot of them OnePlus has too + a few more, which I had all enabled

I didn't really get any notification during last night, so I doubt this was the culprit

Also, unless you are using the app to lower the refresh rate, you may be running a bit high when idle.

Yes I'm using that app and have it set to 48-96Hz


Appreciate the help, I believe there must be something that's unintentionally draining and while I went through every single setting in the beginning, I'm still very new to OneUI (and also impressed how far it came from the TouchWiz ****show)

One thing I always forget is that a lot of those features are running services and polling when they're enabled. Even though I'm not touching the screen with the tap to wake enabled, it's constantly waiting for that tap when it's asleep. Any one isn't a big impact, but Samsung has so many "convenience" features that I end up wasting battery to never use.

The calibration period is also horrible. Android 11 is slow to calibrate the battery and Samsung is worse. You can get a good idea of what is draining battery by going to Settings -> Battery and device care -> Battery. That may help find out if it's a renegade app.

One thing Asus does that I wish Samsung would embrace is Auto-start management. Some apps aren't efficient at polling for notifications and more than once have been the cause of major drain.

Another one even Samsung admits to be a source of drain is the edge panels. If you don't use them, it's best to kill the entire feature.

I just assumed it's not a big impact as OnePlus has those as well, for example draw a "V" on screen for flashlight or ">" to skip song besides the regular double tap to wake and it never appeared to be a battery issue for me before.

Do I assume correctly that some system apps or similar are hidden there? I just did the calculations and the percentages only make up 43.6%. I attached a screenshot

OnePlus also optimizes them better than brand new Samsung firmware. I had a lot of stuff enabled on the Note 20 Ultra that I won't be using for a month or two now.

Some apps are excluded, but it will let you know if it's something not included with the phone.

Another good idea is to uninstall, disable, or "adb uninstall" any bloat you don't use. Besides clearing up space in the app drawer, it kills off services you don't use. A lot of the apps will run services even before you sign in, even though they aren't actually handling any data.

I already went through the list and uninstalled which I 100% knew what it was and that it's not needed, but not sure about 99% of Samsung stuff. Some Samsung apps on the phone I don't even know what they are and when I start them it just prompts to agree to some terms before starting the app... I'll have a look around for a Samsung debloat list

If you have the unlocked version, they allowed uninstall for a lot of apps that were previously locked. A lot can also be downloaded later from Google Play or the Galaxy Store if you change your mind.

I use Firefox, so I uninstall Samsung Internet and Chrome. Members and Health are two big ones that like to run those "please enable us" services. It's a lot of deciding what you might use versus what you can live without.

Another good idea is to add anything you won't use, but didn't remove to deep sleeping apps to kill it's ability to run in the background. It's the closest thing to auto start management without rooting.

Yeah I do have 57 apps there already


I just removed 85 apps/services via adb, let's see how it is tonight and I'll report back tomorrow

Thank you for taking the time, mine is also going down %30 overnight. would love to hear about your result.

So far I don't have much hope sadly. Whole day currently at home and not using the phone much and it's looking like in the screenshot (screen off, loosing almost 2.7% per hour, as comparison my OnePlus is at 0.9% per hour)

https://imgur.com/RLITZwQ

It's 21:21 at the moment and I'm at 54% after 9h 42m (comparison OnePlus with 815mAh more: 7% after 79h with 2h54m SOT)

I'll probably head to bed in a few hours and then report back tomorrow morning how much I lost during the night..

 

[twistedumbrella]

I'm not claiming to have amazing battery life, since I almost considered keeping my trade-in and returning this one over it. I am interested why it is so bad for others, though.

HOLY **** I would love to have this battery life. I'm literally not doing anything with the phone and just loosing so much. I'm pretty much the opposite of a power user, so my phone is in standby most of the time and loosing so much is pretty frustrating.


EDIT: I might have an idea why it's so bad for me, I don't really have reception in my apartment (as you can see on my screenshots), so I assume it's constantly trying to get better receptions, I see 2 bars sometimes, but most of the time 0. I'll keep my phone at the window where I have reception for the rest of the day and see if it makes a difference. (Although the OnePlus has also bad reception, but does have a different carriers SIM card)

Dependencies, dependencies, dependencies... some of those apks just sit there unless needed.
Do not disable apks/services unless you know what they do and what, if any, their dependencies are. Go too far and you'll end up in a boot loop.
What works for others probably isn't ideal for you.
Package Disabler is a better option as you easily toggle apks on/off as needed.

Screen off the serial offenders tend to be Google backup Transport, Framework and any cloud apps.
Try disabling Google play Services at night and see if that helps. You may need to disable Find my Device first as System Administrator if disable is greyed out.
Disabling play services also kills Gmaps and Playstore which are know hogs. Gmail as well to a lesser extent.
Google Firebase, do you need it? If not disable.
Carrier, Google, Samsung and app feedback, disable.
Using power management can cause erratic behavior and not solve the problem. Treat each power hog on a case by case basis instead. It takes a lot longer but yields a cleaner, more stable setup.

Play with it, go through -all- the settings. It's actually quit fun to explore and almost impossible to crash and burn.
