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

batteryusage.png



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.

    While my Battery is fairly good (8-9h SOT) i couldnt care less in todays world tbh. I go to work? wireless charge while i dont use it. im at home? wireless charge. so i would never run out of battery anyway.

    On the Fold your screen off power consumption will give you an idea what's mucking it up in the background. Tap on AOD* runs at about .5%@hr, always on at 1%@hr. That's with internet/phone connection on, Google play Services off and all cloud apps disabled. If you're using much more battery usage than that, you got background apps running that don't need to be.

    *analog clock, self adjusting brightness. The newer phone's hardware should be more efficient than my 10+'s with screen off. Since the Fold has 2 batteries, they likely have separate power controllers. This may impact battery usage slightly as can more display pixel usage.
    Thanks for all the great advice on power saving tips :) and I have zero doubt all of them will help extend battery life. However I bought my £1600 Fold3 as a natural upgrade to my Fold2. I bought it to use fully not to disable lots of features. My Fold2 ran fine with all functionality enabled and got a full day easily from a full charge . That's not the case with Fold3 which has a 10% smaller battery but a 30,% less SOT . As I am beyond the returns period With Samsung I have 2 options available... 1. Get used to charging twice a day or 2. Sell it . I will wait until Android 12 comes out later this month then decide in the new year.

    Having a fast, stable platform that fulfills its mission is far more important than having the latest updates.
    My current OS load is over 1.5 years old, still fast and stable with minimum maintenance.
    Last update was over 2 years ago. Never any malware forced reloads and all data is redundantly backed up anyway.

    Every time you update you introduce new variables. If you have a good load updates can only break it.
    Any bugs they create will require time to find solutions or work arounds for*. Meanwhile my dinosaur OS just keeps on working predictably.
    More play time... less troubleshooting time.


    *if they exist, sometimes broke is broke.
    Each to there own mate ... We live in a democracy so patch or run on outdated os your choice :)

    Life is moving faster and faster paced all the time and hacks and vulnerability are being exploited more and more each day

    It's no longer a question of WILL I be hacked it's WHEN will I be hacked

    Nobody on this forum will thank you for advising them to disable OTA when their bank account is emptied because they didn't apply security updates regularly

    Back to the OP topic tho battery life is poor on the Fold3 and for me it's bad ebought that I might give up on Samsung's foldables and go back to candy bar fornat. I am old school, my first phones were Nokia 3xxx range with 5 to 7 days battery. I need 1 full days usage from my smartphone - and using out of the box settings - nothing else is acceptable for the huge money manufacturers charge these days .

    Let's agree to disagree mate :)

    I'm a pragmatist; I use what works best. Hype doesn't get the job done.

    Redundant backup for everything, not just data.
    My account$ are fully insured.
    The user themselves are the most likely to load or download malware... weakest link.
    Many don't even have their critical data backed up redundantly. Some data can't be replaced.

    A constantly changing platform means malware is harder to spot by behavior. If I can't ID/correct a glitch, it means reload time, zero tolerance.
    Not saying it's impossible to be compromised but it's highly likely unless you do something stupid.
    A reload costs me about half a day to get back 100% unless the SD card gets hit too then add 4-6 hours to the reload.
    Pie is high enough to stop the worst rootkits that require a reflash.

    I'm running 2 N10+'s. So I can't predict exactly how that hardware or UI will respond on the Fold. Samsung tends to use similar power management though and have the same issues.
    The only reason I ended up with one running on Android 10 was its manufactured date, oops🤣
    However it was interesting to compare and use the 2 OS versions side by side with the same hardware and 3rd party app loads.

    It could be that the Fold updates will bring fixes to bugs in Android 11. Samsung has heavily modified it as they did with Android 10.
    I probably roll the dice for those.

    Jumping to 12 though may bring more bugs than fixes. More than once I've seen Samsung firmware and app updates break the phone or app completely over the years🤣
    So I tend to be very conservative especially if things are running well.
    It's always safer to let others be the lab rats...
    Bugs are inevitable in a major OS update

    However my s21u is smooth as butter on android 12 and I can't find ANY bugs so far and I'm getting around 10hrs SOT on s21u from a full charge and all default settings / 120hz adaptive refresh etc

    So I'm kind of crossing my fingers battery life on Fold3 improve with android 12 update

    I dont get more than 6hrs of SoT
    You're complaining about getting only 6 hours of SOT from the largest phone screen ever at 120Hz? And it fing folds too?

    Some customers are difficult to please...
    2
    Well they could have put two batteries given the extra space, plus they always said they made optimisations so we would like to actually notice them.

    But i agree we are difficult :D
    There are 2 batteries. It's still pretty awesome what they've put in this bad boy, though. One side has 4 cameras, 3 mics and a screen, the other has a camera 3 speakers (very good ones too) a mic and 2 screens.

    I honestly think that this is the best overall phone made, if you want the really big screen. I also think it'll be the best until the Fold 4.

    But yeah, we're difficult. I too want more, but I'm ok to wait 😁

    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.
    4
    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
    If you have no 5G signal, why disable it?
    So your phone isn't constantly searching for one.
    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.
