Try the ADB AppControl app to debloat your Foldz.
It works great with all Samsung devices and very simple to use. No root needed.

How much does battery saving mode limit the phone? if I just use it with 60hz how much screen on time will i get with this new update?

it's worth mentioning that after the update I can no longer use power saving and 120Hz at the same time. Looks like Samsung patched the bug....

Something was definitely draining my phone yesterday, as I charged it to 40% in my car (we were without power for three days, just got it back an hour ago) before putting it on Airplane Mode with Location and NFC turned off, just Bluetooth on to play music on my speaker for two hours. This usually, with Wi-Fi and cell service and everything else on, uses 10% of the battery. My battery went down to 13% somehow! After later restarting the phone, the issue was fixed and today it has been draining normally even on 4G.

Last night, while sleeping, I put the phone into the most extreme Power Saving mode (the last box on the bottom of the options list) to make the battery last over one day long, and it really worked because it was about 97% when I went to bed and 93% when I woke up, and my e-mail notifications still sounded. Impressive.

My fold 3 drains about 1% per hr sleeping normal mode with watch connected. My note20 ultra does the same.

This was over a ten-hour period on 4G, but I don't think it would only drain 1% per hour when not used (I use AOD and multiple PUSH e-mail acc'ts and often get Instagram and Messenger and sometimes text messages while asleep, plus Bluetooth and WiFi, among other things). I always charge it at night, so I don't know, but I don't change any settings for night usually. I'm always on it during the day, so I don't know what leaving it for an hour would be. But, the battery is great on this thing. Other than the other day when something was messing with it.

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.
Nope

My usage battery life has stabilized at this level. 4g/wifi, connected watch, secure folder, 120hz, no power saving. Using main big screen most of time for yt, web, online shopping, whatsapp vid call.

I consider this really good battery.








Previous average
Battery life is improving for me. Last week was avg 7h17m SOT.

Battery life (or sot) is ok for me. Usually 5.5 hours for a day of about 15 hours.

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...
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 😁

    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 :

    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.

    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.
