Point is tho I didn't pay £1600 to disable and re enable functions several times a day - or to spend the time changing dozens of settings on my new phone just to get to bedtime without running out of battery on an average day.

As for OTA I agree first release of a major OS upgrade will have some bugs and maybe non optimal battery drain. However these bugs get fixed (eventually) and I'd rather have latest Google security from OTA on day of release than risk being hacked

(I work on the IT industry by the way)

So yes don't he a beta tester if you dont want to run with a buggy OS as your daily driver ... But always ALWAYS always leave automatic updates enabled on your phone or PC ... That's my advice to all XDA users!

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.
[Samsung Galaxy Z Fold3] blackhawk:
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.
[Samsung Galaxy Z Fold3] Talderon:
I'm lucky I guess as I work remote and everywhere I go, I have easy access to power and have a Battery Bank that I keep nearby in case (I carry a backpack normally when I am not at home) and in all honesty, I have not run into many issues where I have needed to use my Battery Bank. I get plenty of usage out of my phone in a day and not have to fear the battery at all.
[Samsung Galaxy Z Fold3] blackhawk:
That's good SOT.

Li's like frequent midrange power cycling roughly 40-80%. Using them like this can greatly extend their usable lifespan by hundreds of full charge cycles. High cell voltage, high temperature and fast discharge rates can cause rapid or accelerated decline.

I just accept the fact that the battery will need replaced every 1-2 years in a heavily used device.

There's only so much you can reasonably do while preserving usability. After a Li is losses 80% of its original capacity, it is degraded and has reached the end of its usable service life.

It needs needs to be replaced.

Degraded Li's are more likely to fail which can destroy the phone.
[Samsung Galaxy Z Fold3] dezborders:
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 :)
[Samsung Galaxy Z Fold3] blackhawk:
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.
[Samsung Galaxy Z Fold3] jeromepearce:
Unless you are connecting to dodgy free wireless, installing dodgy apps or clicking on dodgy links, you are very unlikely to get hacked. I've been using computers on the net very intensively for 25 years, and smartphones intensively on the net for 16 years, without a single hack or even a virus.

Most of my problems have been caused by upgrading the OS or apps, so I avoid it most of the time until updates are proven not to cause problems.
[Samsung Galaxy Z Fold3] dezborders:
All power you you mate

99% of ppl are not so organized as you are and for them prevention is better than cure

One question tho if your os is 1.5 years old how can you be using Z Fold3? ZF3 can't be running older than 3 months os and apps?
[Samsung Galaxy Z Fold3] Nsoo:
Thanks so much for getting back to me!

1) Not sure what you mean or to do?

2)done from the apps menu and then device manager

3) Done that already with no change.. I even lost !y galaxy watch 4 and had it to set it up again.

4) done

5 and 6 not sure how to do it but I need Gmail as I'm using it

And.. few hours before your message as I was a bit desperate did a factory reset and the issue is still there and maybe even worst.. https://ibb.co/ck2ZZLM .. really don't know what to do anymore
[Samsung Galaxy Z Fold3] blackhawk:
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...
[Samsung Galaxy Z Fold3] dezborders:
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
[Samsung Galaxy Z Fold3] blackhawk:
It very well might improve.

Samsung had to heavily modify the UI for it to work with 10 and certainly for 11/12. It was no small task. Lol, Samsung's UI was already the most tricked stock UI to begin with.

Just compare a Samsung running on 11 or 12 to a Pixel. It's hard to believe it's the same OS.

Counterpoint to that is to get while the getting is good. If you think the Fold series is not viable now's the time to get top dollar selling it. If Samsung drops the Fold, it will be a dead end with more limited future support including firmware.

Samsung hasn't released sales numbers for the Fold 3 apparently but says it's the best selling Fold ever.

You can tell I'm heavily biased by my weapons of choice, the N10+ running on 9/10. Draw your own conclusions based on what you want and observe in the market. Go from there.
[Samsung Galaxy Z Fold3] WZDISMINE:
I have now 3 fold, regarding the price, this phone its fantastic amazing. But, It's gift for my wife 😇. For my self, I need something next level: (Battery 🔋)
[Samsung Galaxy Z Fold3] pulyka:
Hey, I have the same battery issue.. samsung says 4400 mah, its nowhere near. However its slowly going up as I charge it more.

This app has been accurately working for my older phones in the past. Is it possible that samsung does not allow us to fully charge this battery to 100%? (Like electric cars - to save wear cycles...)
[Samsung Galaxy Z Fold3] blackhawk:
Pretty typical for Accubattery. It's all relative... more a general indicator than an absolute.

If it makes you feel better set the battery capacity at 3832 mAh.

Now you have 100%... I do this on my N10+'s🤣

If the top charge voltage is near the cell's nominal rated voltage than it's fully charging it.

It's a $20 battery, not a $5G one... you can limit the top charge to 80% to extend its service life though if you wish.

When it reaches about 3200 mAh I will replace the battery. The battery is rated at 4300 mAh but Accubattery never saw it as such.

Whatever🤣
[Samsung Galaxy Z Fold3] Allesa:
Snapdragon 888 is not more power efficient than 865. Google it. It's a power hungry chipset that has been heavily criticized this year. It's faster yes. But cant sustain the maximum performance for longer period of time, only short bursts. Power hungry --> heat --> thermal throttling.
[Samsung Galaxy Z Fold3] dezborders:
I stand corrected ;) However I am not a power user and I dont play games so sustained max performance wont be a problem for me.

I have now sold my ZFold3 as its incapable of running a full day on one battery charge for "normal" usage. Maybe I will try Z Fold4 in 2022
[Samsung Galaxy Z Fold3] Allesa:
Yup.. Sold mine too a month ago too. Checking out this thread to see if somehow magically Samsung found the magic sauce to reduce 888's battery consumption but apparently not. For a device screaming to be used 24/7 it doesn't have the juice to do so
[Samsung Galaxy Z Fold3] blackhawk:
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.
[Samsung Galaxy Z Fold3] Allesa:
In theory yes. But in practice no. Just google it. This one article is just an example. Read first paragraph. It is quite well known til now 888 tends to overheat and burn through juice more than 865.

How do I know? Not just from articles. This is my channel. Not an english speaking channel tho. Reviewed enough SD888 phones and i'll take 870 or even 865 anyday.
[Samsung Galaxy Z Fold3] blackhawk:
Perhaps. Lack of adequate heat sinking is likely the real issue. Prolonged high intensity gaming on a phone like this is unrealistic*. There are physical limits to how much power you can use and still safely dissipate the cpu's waste thermal energy. It's not just the chipset; Li's are stressed when subjected to prolonged high current drain rates.

If there actually is an issue a future instruction set update will likely correct it.

The processor is the least of this phone's issues if it's properly heat sinked.

*on my N10+'s I limit games to 10-20 minutes before giving it some rest time. Charging isn't rest time, doing a low demand activity like using the browser is ok. I do the same when streaming vids although the usage interval is increased. That's more to protect the battery than concerns about overheating the chipset.
[Samsung Galaxy Z Fold3] dezborders:
Ditto... I will continue to review this thread in the vain hope that the (now delayed) Fold3 Androind 12 Upgrade solves the poor battery life situation. I can always pick up a 2nd hand F3 on eBay or Facebook if this wish comes true. (But I wont hold my breath).
[Samsung Galaxy Z Fold3] dezborders:
I have to admit I now regret selling my Fold2 in September and upgrading to Fold3 lol.

I will sit on the fence until Android 12 update has been out a few weeks to assess if its any better in battery life then decide.
[Samsung Galaxy Z Fold3] dezborders:
Just one side comment... I ran with Mi 11 12/256 as daily driver for a month and that has an SD888 and got 8-9 hrs SOT.

Ditto for an Oppo Find X3 Pro... SD888... 8+ hours SOT.

Also worth pointing out i am NOT a gamer and I dont take 100s of pics daily so use camera lightly.

With the above experience in mind I am not 100% convinced that SD888 is the *main* casue of poor battery life on the Fold3.

... and gives me hope that Samsung can "fix" the issue in software. ... fingers crossed for Android 12.
[Samsung Galaxy Z Fold3] tigsandmitch:
hopefully it can only get better and not worse......(famous last words)... :')
[Samsung Galaxy Z Fold3] blackhawk:
Both Samsung and Android 11 have been bombs this year. Multiple issues on both and many with no viable solutions. The 2022 outlook is still bleak especially for Android. Android 12 will not resolve many of the issues particularly scoped storage.

Last solid Samsung flagship release in my opinion, was the N10+ Snapdragon 4G variant running on no higher than Android 10. Doesn't have variable refresh rate or 5G but it's display's color rendering is superb exceeding the variable rate ones. Running on Android 10* scope storage is inactive at least on older apps (including office) which will install. No SD card interface issues.

That's why I have two N10+'s now; the oldest running on 9, the newest bought 2 months on 10. Both are solid drop dead gorgeous work horses that get the job done and have up to 1tb expandable storage. The one that's over 2 yo is heavily used and shows no signs of wear or display degradation other than one battery replacement. Current OS load on it is over 1.5 yo.

Never any forced reloads due to malware on this outdated stock Android 9.

Tough choices. I decided to bug out, regroup and dig in until Samsung, Android and the app developers get their $hit together🤣

Buy what best fulfills your mission requirements.

The rest is just useless hype...

*both N10+'s will never be updated past Android 10, OTA updates are disabled, quit deliberately.

The Android 9 variant may be upgraded to 10 but as such it remains viable with adequate security.

It's fun to compare the two OS's, the 9 variant has more tools for troubleshooting than the 10.
[Samsung Galaxy Z Fold3] Mr. Orange 645:
I forgot to take a screenshot and threw it on the charger for a couple minutes, so you see a little increase there at the end. It was 17 or 18% battery when I put it on the charger. I'd say over 7 hrs screen on time, with a LOT of Facebook which is a known battery hog, and still have 17% left is pretty decent. And all of that is on the inner screen.

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?"
[Samsung Galaxy Z Fold3] Cyrax-001:

[Samsung Galaxy Z Fold3] OJsakila:
WOW. This is great news to hear about nearly 7 hours! Currently my locked to AT&T z3 is updating to the new software.. I elected to do a full reformat since its an entire OS update and I guess the Samsung UI is applied at the same time? Either way, I have no problem spending the evening tweaking out my phone...
[Samsung Galaxy Z Fold3] Mr. Orange 645:
Here's mine today. 5.5 hrs screen on time with 24% battery left. Similar to my over 7 hours a couple days ago with 17% left.

U1 model running the latest Android 12 beta. No power saving settings turned on. I don't have anything turned off either. Did a factory reset and didn't restore anything. Fresh clean set up after getting the latest beta.
[Samsung Galaxy Z Fold3] OJsakila:
Solid. +1 Apparently, I do NOT have the AT&T locked update available now since I reformatted. I could have SWORN that it was there (IT WAS) and once my phone reset last night, its not there anymore. grr.. Ive been checking all day and its just not there. I'm super disappointed. lol
[Samsung Galaxy Z Fold3] Hardcastle123:
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. .
[Samsung Galaxy Z Fold3] m_w_clarke:
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.
[Samsung Galaxy Z Fold3] Hardcastle123:
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
[Samsung Galaxy Z Fold3] m_w_clarke:
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.

This is super helpful, thanks! But for other people trying this, I would recommend not uninstalling com.sec.android.app.launcher and com.sec.android.app.desktoplauncher unless you are already using another launcher. It also leaves you without the "recent apps" functionality even if you are using something else.

After a couple days of making the tweaks here, I've been able to obtain 4H 41M SOT over 2 days usage. Very happy with this!
[Samsung Galaxy Z Fold3] montrealbagel:
really bad on mine!
[Samsung Galaxy Z Fold3] Batfink33:
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!
[Samsung Galaxy Z Fold3] ycats:
I don't.
[Samsung Galaxy Z Fold3] jeromepearce:
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.
[Samsung Galaxy Z Fold3] Batfink33:
Thanks. Battery seems a big problem to me, only had the device 4 days but I'm charging a few times a day (not to max each time). I put it on 85% for overnight charging but I'd like that but extra during the day. Really wish it came with better battery life because aside from that, it's stunning.
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
No, I'd much rather use my phone as needed than possibly worry about the battery being a little less in a few years. I didn’t buy the phone to use only 85% of the battery. As it is, I typically plug it in no later than when it gets to the 15% low-battery warning mark since the last 15% always dies super fast on phones for some reason, so I'm already losing 15% of the battery use.
[Samsung Galaxy Z Fold3] ycats:
I used to change phones about every six months or so for years............but usually keep them for a couple of years since the Note-5 came out. So I feel like battery issues are never a problem. I will say the first month I had it, was having drainage issues............but after some tweaks, it's been doing well (got the phone at first release). Hoping the ZFold4 is even better because might trade for that, definitely if they put a 5000mah battery in it and include the stylus, but not holding my breath.
[Samsung Galaxy Z Fold3] Batfink33:
Battery life seems to be better for me today, 5th day in. Maybe ite because I've not been on the phone constantly (new gadget factor wearing off) but I took the phone off 100% at 9am and now at 5pm got 40% left. That's similar to battery life I was getting with the Pixel 6 Pro.
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
Something is draining my battery yesterday and today, and I don't know what yet. I had it on the wireless charger (been using it nightly since getting the phone in August) and woke up in the middle of the night to it lower than when I put it on! I thought it was a certain app that was having a log-in issue, so I deleted the app since I rarely use it anyway, but I woke up for good to it being even lower! I installed Accubattery, but am not sure what the problem app is yet. I'll restart my phone to fix it, but I wanted to use Accubattery first to try to figure it out. Usually, this battery is awesome, so it is odd!

Samsung Galaxy Z Fold 3 battery duration and charging

With the telephone consistently web surfing at 150 nits on cell, it went on for 6 hours and 36 minutes on the inside show set to its Adaptive 120Hz mode. Changing to 60Hz, it bounced as long as 7 hours and 53 minutes.
