I noticed that people who have the Samsung flip case including me should be experiencing more battery drain. When the cover of the case slides slightly to the left and doesn't become flushed with the display the screen turns on ( Process : CoverServiceManager )

It's hard to notice the display because the major part of the screen is still covered.

I've been working on tracking the reason behind my battery drain since 3 weeks because believe it or not the display is not the culprit.

I debloated my Fold 3 using adb and my SoT was still mediocre around 6hrs. Gsam Battery monitor was hinting to something different....

What I did in Gsam was killing all the processes running under Android system section not directly related to the OS and so far my Screen off drain in Accubattery went from 1.5%/h to 0.6%/h at night ~ 90% deep sleep...

SOT is now touching 7h 30mins. inner display @120hz, 5G off ( mails, whatsapp, Youtube Vacant, browsing, phone calls and other social media stuff) as I'm not into gaming.

I will dig deeper to find out which process was responsible for drain but it's gonna take some time....

Below is the current battery usage when the front screen is on and the device is idle

101 - 120 mA with brightness set to Auto ~ 65% vs 150 - 200 mA

I can tell you that those numbers are even better than what I was getting on my Note 10+ which had an amazing battery life so yeah the F3 is capable, it's a matter of time....

Bit cheeky, so np if you won't, but, could you kindly share your ADB debloat script.

Also, I presume those are your 5G cellular speeds. Where are you located? those figures are mightily impressive.

I don't have a specific script because it's a matter of taste some apps might be useful to you but not me. I'll send you a list of all installed packages from adb at night so you could compare and remove what you don't need but I'm avoiding any usb connection right now as I'm watching my SOT after the changes I did.

I also don't remember which packages I removed because it was from multiple sources and I did an extensive research to understand what each one does.

My speedtest results are almost 10 years old 😂 I was testing a fiber connection.

Cheers.

Didn't even notice the date on the test, I was so blinded by the headline figures.

Even more impressive given that where I am in the UK, my 1gig fibre connection only gets me about 800 down and 700ish up.

I'm searching my PC history and here are some of the sources I used to debloat :

Damn, seems like a factory reset is in order, or should I give it a few days to stabilise?

Got the fold 2 days ago. This usage was mostly on 4g with dual sim.

Had the same experience first few days. Turned out it was google photo, album and other apps harvesting pics as I had over 180k photos. Download Gsam battery monitor you should be able to tell what's behind that drain.

I had **** battery at first too. then I came across universal Android debloater and man that changed my phone's battery. I uninstalled so much junk but kept the core Samsung apps I'd need (pay, edge panel, etc) and got rid of pretty much anything else. difference is night and day

Yeah so I rarely use the inside screen for anything so I meant I put the whole thing at 60hz.
You rarely use the MAIN display? Sounds like you chose the wrong device. While that's really none of my business, it's certainly doesn't make sense for you to be weighing in on a battery life discussion when you're not even using this device as it was intended. I'm sure I could get 7-10 days of use between charges if I was simply using it as a clock.

I love the Fold3 but I have to admit that it's not enough battery for such a powerhouse. I mean it has bigger screens than S21 Ultra and the same processor but smaller battery... It's just too weird, sometimes I don't understand what Samsung is trying to do. I can't go back to unfoldable phones anymore so that I'll wait for the Fold4 not the S22

Are you really not near power outlet all day long?
I charge twice a day (drain from 85% to 20% to prolong battery longevity 😀). But I use my phone a lot...coming to 11hrs SOT per day.

Peasants! I never charge my phone. When the battery dies, I just get a new phone.

No...I'm just near a charger all day in reality. But I do think my battery life has got better.
Sure, battery life has got better, but it was from such a low initial base that it hardly matters.

Personally, I think this is part of a Samsung strategy to recoup income lost from the lower pricing this year.

Make us all buy Samsung power packs, kerching all the way to higher profits. I'm surprised that apple haven't latched onto this yet.
 
Is it the case that most of us charge this phone once during the day? Versus the nightly full charging?
I honestly couldn't tell you. I'm a Sheriff's Deputy, so it sits in the wireless charger dock in my patrol car while at work. Then even on my days off, I have a wireless charging pad next to my bed, so if I'm not actively using it, I just lay it on the charger. None that has anything to do with this particular phone or its battery life. It's how I use every phone. I even have a charger and cradle on my motorcycle.

If I do plan to be away from a charger all day, and know I'll be using my phone heavily, I'll just throw my Note 20 Ultra in my pocket as well.

    The 888 has a 5mm form factor vs fat 7mm.
    It likely is more efficient.
    It's not suppose to run wide open except for brief time periods.

    The elephants in the room...
    Variable rate displays and 5G come with higher power consumption.
    AMOLED displays can use a lot of battery and look at all those square inches of displays.
    The physical design of the phone, all that space.
    Longer conductor pathways means higher resistance.
    Android 11, it's a hog. Burning extra cpu cycles for scoped storage.
    Hopefully android 12 will back off a tad and with a good/great reception 5g doesn't seem to be an issue here in Savannah.. I've debloated my crapware and turned off all the background running apps that I don't want running when I'm not using them. I've also been very posesive about my location services and what apps are running there that I really need. I am NOT utilizing any "power saving mode" as I prefer to do that manually and several things that mode shuts off I want on... Like the 120 hz screens.. With this researchable effort I've been able to get a NO PROBLEM battery for this phone with pretty much power usage. 5 hours screen time easy. Maybe other people have "bad batteries?"

    I've had the Galaxy Z Fold 3 about 72 hours now , slightly concerned about battery life when returning to work/life balance next week. Granted media consumption will reduce but still 'Interested' to see how it copes with a 6 til 6 day. .
    If you've only had it 72 hours the software hasn't yet competed optimisations and settled. Mine took a good week or two to bed in.
    After this I get a good working day out of it, whilst streaming Spotify for most of it. At the end of a "heavy" day, I usually have 30-40% left
    Hope that gives you some insight.

    That's great to hear - thanks for the heads up!

    Spotify is easily my most used app , with a similar use case to yours.

    Do you put apps to sleep or use any other battery saving methods? I use dark mode for aesthetic reasons above battery saving but that's all I do really
    I don't use any optimisations really. Dark mode and 120hz refresh. I let the OS put unused apps to deep sleep when it notifies me it's found some I haven't used in a while. You should start to see this notification after you've had your phone for a few weeks.

    I just wanted to know what to expect during upgrade from ver 11. Do i need to make some adjustments after rhe upgrade?
    Here's a link to all we know about the battery life on Android 12 and what, if any, battery optimization steps we've taken to get decent battery life :

    1
    Do people here limit the charge to 85%? I want to to keep the battery safe long term but I really need that extra 15% of charge!
    Don't limit the battery if you need that extra 15%.

    Basically, you can keep the battery life as new(ish) by limiting yourself to using only between 20% and 85%. That means you get 65% of the true battery life. The benefit? You get to keep the battery life as it was instead of it degrading. So if you reduce your battery usage to 65%, you will stop the battery degrading to 65% of its original capacity over a couple of years. That's right, intentionally reducing your battery usage will prevent it degrading to that battery usage, after a couple of years. The benefits are absolutely zero, in fact are negative.

    Having said that, when I'm home, i limit the charging to 85%, because I just don't need that additional 15%. If I'm going out, I will charge to 100% if I'll need extra life. I'm pretty sure that I'll never see the benefits of this during my ownership of the F3, but I don't like waste so I do this anyway.

    You may notice that the charging above 85% is deliberately slowed anyway, so it protects the battery to some extent.

    TLDR:
    Don't bother.

    This happens with every release of every new phone. It always takes a few days for it to settle as it's downloading apps, settings, updates, etc. It's WAY too early to compare battery life. Give it a week.

    please, for god sake how did you do it. just tell me already
    Lol... Just disable or uninstall all unused apps, turn off Google Discover & Samsung Free (the swipe right on homescreen thing), disable Google (the app, not account syncing) and Google Assistant, turn off Bluetooth/NFC/GPS until you need it, use a black theme, turn off unnecessary notifications, error reporting, and feedback, use static wallpaper, stop app auto updates and auto refresh (weather, stocks, etc), turn off always-on-screen.
    I don't do this, but for even more battery use 96hz or 60hz and turn off vivid screen mode.

    WhatsApp has been running for 25 mins and eaten ~30%? You have something deeper going on there it looks like.
    3
    Digital wellbeing is a battery eating feature itself. Turn it off and you will get more battery time.
    3
    Give it time to take a calibration and you to stop using your device not in the muscle memory you and the phone will develop.
    Then they'll push a firmware upgrade that destroys all that hard work you and your new fold put in getting to know one another.
