[Samsung Galaxy Z Fold3] snaske65:
I personally have found an app called galaxy max hz which allows screen refresh rates down to 48hz also allowing you to force 48hz on sleep.

It's probably govern me about an extra hour screen on time.

Cheers
[Samsung Galaxy Z Fold3] dezborders:
Nope, I never have limited battery charge before so why start now... and Samsung gives a 2 year warranty anyway ;)
[Samsung Galaxy Z Fold3] bmwjavier45:
I have never had a phone with a battery as bad as this one. Barely 17 hours, all the time on Wi-Fi 6, and it doesn't even get to 4 hours of screen on time. A shame. I will have to sell it.
[Samsung Galaxy Z Fold3] dezborders:
Saldy I agree 100%. Also my high hopes for improved battery life with Android 12 upgrade did not come to pass.

Battery life is the single biggest thing Samsung need to work on before they release the Fold4 in 6 months.

(Battery life is also dismally poor on the Z Flip 3)

... it's almost as if Samsung is deliberately sabotaging foldables so that they NEVER reach mainstream sales figures.
[Samsung Galaxy Z Fold3] Batfink33:
Is it not just that they're trying to make it as thin as possible? Bigger battery means thicker and heavier. I thihk it'll be sorted eventually with iterations of the phone but the Fold 3 on the big screen destroys the battery.
[Samsung Galaxy Z Fold3] tigsandmitch:
I found with the BVA9 update I get better battery life.
[Samsung Galaxy Z Fold3] dezborders:
Yes that's why Samsung reduced battery size - smaller and lighter device

But what use is a £1600 device if it can't last a full day on a 100% charge ?

(P.S. It's still big and heavy compared to "normal" phones so what was the point in reducing battery size and thickness )
[Samsung Galaxy Z Fold3] Batfink33:
Yeah I don't disagree. FWIW, my P6P wasn't lasting the day either and I charged it at roughly the same point as I do the Fold 3 but I mostly use the small screen during the day. The s21u I had was much better though and lasted the day. I could get a days use using the outer display but no way using the big display.
[Samsung Galaxy Z Fold3] m_w_clarke:
Horses for courses, I guess.

Very very rarely had battery issues with my phone. But, it depends on your use case. I'm fortunate to have full strength 4g signal in 90% of places. I've turned off 5g as for me, the improvement was negligible. Working from home, most times its connected to my home WiFi-5.

Being in the UK, the screen brightness and ambient temperature are also both low which I guess saves some juice.

I get easily a full day, with around 30-40% left in the tank of a typical day.

BUT if I do venture to a place where signal is sub optimal, then I do see a faster battery drain.
[Samsung Galaxy Z Fold3] dezborders:
Oh I wish!!! lol (30% battery remaining at end of my day)

I live in an area with only 1 bar of signal indoors, but as I WFH I am on Wifi almost constantly.

Perhaps even on WiFI, the low signal still causes me excess battery drain whilst "hunting" for a better signal constantly.
[Samsung Galaxy Z Fold3] Batfink33:
That's interesting. As an example, I took it off charge this morning at 11am. I use the max charge of 85%. Now at 9.35pm I'm at 15%. I mostly use the small outer display though during the day with it opened for only maybe 30min. Do you use the big display? If I used that, the battery would be gone in a couple of hours. I don't find the battery life great but it's not causing me any problems specifically.
[Samsung Galaxy Z Fold3] dezborders:
I can get 4 hours of SOT using a mixture of inner and outer screens

However I was seeing 7 hours SOT when I had a Fold2 ... Big drop !
[Samsung Galaxy Z Fold3] Batfink33:
Yeah that is a big drop. I guess the higher hz and smaller battery might be cause this then?
[Samsung Galaxy Z Fold3] dezborders:
Yes to both .. and from what I have read online the SD888 is much more hungry for battery power than previous CPU (aNd the latest SD 8Gen1 even moreso)
[Samsung Galaxy Z Fold3] Batfink33:
Ive went from the s21u to the P6P and then to the Fold3. Tbh I wish I'd never sold my s21u because it was probably the best of all of them and I would've upgraded to the s22u now. The P6P battery was pretty awful and the phone overheated on 5g for me so getting to the Sd888 was a nice change after that but the Fold3 isn't perfect at all. I'll keep my options open as to what to get next but hopefully Samsung addresses the battery problems on the F4.
[Samsung Galaxy Z Fold3] dezborders:
I had an s21u 16/512 around November and I managed 9hrs sot

Those were the days lol
[Samsung Galaxy Z Fold3] Cyrax-001:
wow dude, why would you buy a Fold if you're gonna use that tiny screen most of the time?
[Samsung Galaxy Z Fold3] Batfink33:
I'm out and about and busy. Not practical to open the display when you're walking around and busy with kids etc. Use it to watch videos etc later at night when I can relax.
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
If your battery is draining fast, reboot your phone. Something in the system seems to start to drain it at times, as it can't be found on the app list in the battery use section. Like today, I noticed that it was already down to 67% way earlier than it should be, so I rebooted it, and hours later, it was only at 50% as usual (with use, obviously).
[Samsung Galaxy Z Fold3] whatwhatster:
My battery got better generally, I always do 2 days with it and a combo use i

Outer/inner screen. I never use battery saving.
[Samsung Galaxy Z Fold3] iceepyon:
There is a learning phase for the Z Fold 3 to learn how you use it. Once the battery monitor AI has learned your usage pattern, the battery life should get much better
[Samsung Galaxy Z Fold3] Nastrahl:
Plot twist : it does not.

I do have to charge it twice a day. I never understood how do the users do to have 2 days of battery or 8h+ of SOT with actually using it with a few apps and just not leaving idling in an black screen with every sensors off and apps uninstalled.
[Samsung Galaxy Z Fold3] blackhawk:
Global power management never worked right.

Turn off all that junk, deal with battery hogs on a case by case basis. Individual app power management in settings does not invoke global power management.

-All- Samsung's need to be hand optimized for best battery life. On this device it seems to be critical. Use manual brightness control and avoid using is direct sunlight! Limits that to seconds not minutes. Temporarily disabling Google play Services will improve battery life; Gmail, Playstore, Google backup and Playstore are dependencies. All suck battery. No SD card slot makes you more depended on cloud, not good for battery life.

As for Android 12, avoid it... it's a mess.

In the last 2 years Samsung has been dropping the ball constantly... and continues to do so.

Last superb flagship release was the N10+ in my opinion and it still exceeds the newest releases in a number of mission critical ways including reliability, battery life, display color rendering index, form factor and expandable storage.

2 years, 3 generations and Samsung is still goofing up on its flagships... poor leadership.
[Samsung Galaxy Z Fold3] iceepyon:
I've had my Z Fold 3 for around 2 weeks now and I can get through a whole day with a single charge. I use my Z Fold 3 in tab and phone mode. I am quite a power user and use it mostly for gaming, media consumption and web browsing. I also use it for responding to emails and sign documents.
[Samsung Galaxy Z Fold3] blackhawk:
Yeah but that will change as the battery degrades. At least it's only one battery to replace on this model.

My N10+'s 4300mAh battery's average usable lifespan is about 14 months... it's heavily used.

So you'll likely make 1 year, but 2 will be hard if heavily used especially in high ambient temperatures. Always replace Li's when they reach 80% of their original capacity to avoid a failure... which can damage the phone.
[Samsung Galaxy Z Fold3] iceepyon:
That is the same with every electronic device.
[Samsung Galaxy Z Fold3] blackhawk:
You want enough reserve capacity to last the usable lifespan of the Li...
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
I'm a heavy user and the phone battery lasts good enough for me. However, one of my apps lately they updated it and it is killing the battery for no reason, like it is in the background except for a few minutes a day, and using as much as 40% battery. I can't delete it because it is for a medical device I need all day, so they just need to fix the app fast (I've talked to them already, and the app also crashes often). So, if your battery is draining, check the battery section of the settings to find out which app it is.
[Samsung Galaxy Z Fold3] becosemsaida:
Well i WAS (yes, WAS) about to buy this phone but you all scared me away from it........ I need a phone that lasts me through the day that may vary from 16H or more.. But let me give you my opinion on this thread, so in order to have a "flagship", top of the line, expensive phone i need to treat it as a Nokia 3310?? Right, i NEVER used anything that is compromising the full capacity of a phone. Using Note series from day 1 and now on Note20U and as a heavy user i will not starting compromising for a foldable one. I refuse to charge 2 or even 3 times a day, not possible. And charging several times small amounts will damage your battery if you do it a long time. I don't care for camaras but i need it to be productive, the larger screen would be a nice upgrade but to sacrifice not having a full day of usage is a big no no for me. Now i have to wait for the F4 to come out and see what Samsung did with that and maybe in a year or so i will consider a foldable.

Beco
[Samsung Galaxy Z Fold3] hkr:
You will be disappointed, don't expect F4 to be a battery wonder ... Foldables will always stay behind a phone with one screen.

Besides, if rumours might be right, F4 will be thinner than F3 therefore don't expect a big, bulky battery
[Samsung Galaxy Z Fold3] Nastrahl:
Indeed, but given the place taken by the SoC and a standard phone, they could have put two batteries instead of one to double the battery life.

Also, the image definition of less than a usual smartphone so it should actually take less battery.
[Samsung Galaxy Z Fold3] Cyrax-001:
there are already two batteries
[Samsung Galaxy Z Fold3] Nastrahl:
My bad
[Samsung Galaxy Z Fold3] jirka607:
Can you show what you debloated.

I will attach my list but I wonder if debloating can actually cause higher drain....so please let me know if I removed something I shouldn't have:

[Samsung Galaxy Z Fold3] RR-99:
My Fold 3 is now running down much faster. It's now only just lasting the day, where it was lasting two days when new with just about the same set of apps.

I'm hoping that Sam will have good tradein deal for the Fold 4, don't fancy getting new batteries for the 3.
[Samsung Galaxy Z Fold3] blackhawk:
Replace batteries as needed to avoid a device damaging battery failure. Any swelling is a failure; do not charge in this state, replace asap💥

A Li has reached the end of its service life when it reaches 80% of its original capacity. It is considered degraded and should be replaced.

This is just routine maintenance, no big deal and important to do. Try to replace with a OEM battery and replace any factory seals that were breached with new ones.
[Samsung Galaxy Z Fold3] RR-99:
Well it's two batteries to be replaced, so I'm going to hold on for the Fold 4 release. If I can get a good tradein deal I'll take that, otherwise get the batteries replaced.

Interesting that Sam recommend limiting charge to 85% to prolong battery life. I haven't notice that with my Note phones.
[Samsung Galaxy Z Fold3] blackhawk:
Yeah two, ain't that swell?

Just keep an eye on it. If you see erratic fast charging happening that's a sign its failed.

This heavily used N10+ battery failed at about the 16 month mark. It took me a month to recognize that I had a battery failure in progress rather than a charging issue🤣 i was very lucky the swelling didn't damage the display. It's always cased so I didn't see the rear cover was bulging😖

I generally limit the charge on my N10+'s to 80-85% in part because after 80% and especially 90% fast charging ramps down a lot. Not much juice for the time. Li's prefer frequent midrange power cycling anyway so a charging limit at 85% is a good plan. My lower limit is 40%. Below 20% places higher stress on the battery because of increased temperature.
[Samsung Galaxy Z Fold3] Nastrahl:
increased temps while charging isn’t supposed to be mitigated by USB PD which Samsung’s chargers are ?
[Samsung Galaxy Z Fold3] blackhawk:
The phone's power controller will first ramp down the charge rate at predetermined temperatures then if the battery temperature gets too high terminate that charge cycle.
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
Have you checked how much battery each app is using? App updates/device firmware updates can sometimes cause the same apps/devices you've been using to eat more phone battery. Like, it happened recently with a Facebook Messenger update, whose previous update kept randomly rebooting my phone up to four times a day, and then they fixed both issues. And with a Bluetooth medical device I use, suddenly the app started draining my battery like crazy after a device firmware update and app update, and they've only partially fixed it (no new firmware update for the device yet, but the app update did lessen the battery use a bit, just not nearly as low as it used to be) - it was using up to 40% of my phone battery at one point, whereas before it was using like 0.6% each day. It isn't something I can put in deep sleep like Android Settings keeps suggesting.
[Samsung Galaxy Z Fold3] RR-99:
Yes I have been monitoring apps and there's not one single app using a disproportionate amount of battery. It just runs down more quickly that it used to.
[Samsung Galaxy Z Fold3] BLEK0TA:
after year i have from 5hrs SOT only 3hrs SOT now
[Samsung Galaxy Z Fold3] ycats:
Maybe it will improve after the update to Android 13. I did upgrade to the ZFold4 in August, at the time, Samsung was giving $1000 for the ZFold3.
[Samsung Galaxy Z Fold3] Nastrahl:
Hello,

Oddly don't have any settings related to motion smoothness.

Had 8.0.0.3, updated to 8.0.0.10 with no change related to this

(Premium activated).

I tried to delete the cache and data too.

Thanks
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
I can't read the language in your screenshot, but it doesn't have the graphics on the page mine motion smoothness in the US is on, so I'm guessing you're not on the same page. Motion smoothness on mine is on the "Display" page, and then you tap "Motion Smoothness" to choose either "Adaptive" or "Standard". I have mine on Adaptive since my migraines are affected by scrolling/motion.
[Samsung Galaxy Z Fold3] Nastrahl:
You understand it well nonetheless 😌

I indeed doesn't have anything related to display inside the app and i don't know why.
[Samsung Galaxy Z Fold3] Nastrahl:
Alright i just noticed I'm actually in the wrong thread.

🙃

Sorry.
[Samsung Galaxy Z Fold3] ButterflyFlutterflyMyOhMy:
Okay.
[Samsung Galaxy Z Fold3] dezborders:
Update ... Good battery usage today ...

- cleared app cache

- set mobile network to 2/3/4G only (there's no 5g where I live)

- disabled WiFi auto switch to mobile

- charged to 100% then rebooted

AccuBattery now shows 42hrs standby 22hrs mixed usage and 7.5 hours estimated SOT

Finally my Fold3 battery usage is as good or better than Fold2 was :)
[Samsung Galaxy Z Fold3] Allmightyusfame:
Hello, which app's cache did you clean? All of them?
[Samsung Galaxy Z Fold3] dezborders:
Yes ALL of them

I used all-in-one tool to clear app cache

I also disabled "switch to mobile" in WiFi advanced settings
[Samsung Galaxy Z Fold3] vwite:
what is accubattery telling you in "battery health" tab? mine is 85% not sure if that is just wrong reporting/wrong calculations or if I do have a smaller than normal battery. I did change "design capacity" to 4400 mah.

I know Accubattery may not be accurate but all my phones usually report more than 94%, I'd be more worried if accubattery reports 95+ percent on every other fold3 but mine
[Samsung Galaxy Z Fold3] dezborders:
98%. I just left mine at default estimate...
[Samsung Galaxy Z Fold3] vwite:
well crap, mine is estimating 3,828 mah, not sure if this will be a deal breaker I just spent so much time transferring everything over from Note 20U and Fold2.
[Samsung Galaxy Z Fold3] dezborders:
Set your design capacity same as mine then reboot and charge to 100% and see what AccuBattery says after a days off charge use

Let us know if anything changes ... Fingers crossed 🤞
[Samsung Galaxy Z Fold3] vwite:
I just uninstalled, reinstalled and rebooted and will charge to 100%. Is there any reason why you're using that design capacity? isn't it supposed to be 4400 mah?
[Samsung Galaxy Z Fold3] dezborders:
I just installed the app and that's what figures it selected so I didn't change anything :)
[Samsung Galaxy Z Fold3] lawtq:
You need to change it to 4400. My silver one reported 97%. Will test my green one
[Samsung Galaxy Z Fold3] dezborders:
I installed AccuBattery only to monitor SOT and standby drain

In fact I will probably uninstall the app in a week if battery life remains good lime it is last 2 days :)
[Samsung Galaxy Z Fold3] sabesh:
In.
[Samsung Galaxy Z Fold3] Kinnizle:
So I've had my phone for 24hrs and while I love it I must admit I'm extremely concerned about the battery life. It's just completely evicerating itself. It was at 41% and in about 20min it's down to 15%. Earlier it was going down 1.07% per minute!! Like that's CRAZY! It's literally dropping before my eyes just getting logged into xda after years of being off and writing this message. I get updates and in a few days after the phone settles it might improve but what I'm witnessing is utterly abysmal and even if it slightly improves I don't even know how it'll be usable. Also I don't even have that many apps installed. Maybe 15-20apps
[Samsung Galaxy Z Fold3] mbze430:
I was on a phone call with Samsung Customer service for 37mins I had 42% it dained to 22% by the end of the call. that is alarming. The call was via Wifi Calling
[Samsung Galaxy Z Fold3] whatwhatster:
My first usage after 100% and let my Fold 3 die completely, so a lot playing around and setting up etc so overtime it would be better than my first time right :D

120hz on both screens and no battery saving btw.

Also I had 120hz with power saving combination on my S21 Ultra this little hack is not possible on the Fold3, would be a nice feature if that worked on the Fold3 as an extra.

Edit: Played a little around again with Galaxy Max hz and forgot too activate trial yesterday but having set it up on 96hz constant because variable drops back to 60hz and will this test out with power saving enabled.
[Samsung Galaxy Z Fold3] hkbladelawhk:
Interesting. With most my apps deep sleeping (all 200+ lol). Accu battery only shows a possible 12 hrs combined from 85%.
[Samsung Galaxy Z Fold3] lapeno022:
I have same idle drain.. around 4% per hour, but I have a lot apps, so I think that's reason..

anyway, It's somewhat settled and I can use it lightly for whole day (after removing link to windows and other battery hungry stuff..)
[Samsung Galaxy Z Fold3] dezborders:
Just an update folks after 10 days use of the 256gb UK model ...

I'm consistently getting over 6hrs SOT out of a full charge (off charge between 7am and 9.30pm)

(P.S. I still have mobile network set to use LTE/3G/2G only, as I get zero 5G signal where I live)

So to those suffering battery drain on their new F3 devices ...

... battery life does improve over time with a few config tweaks👍
[Samsung Galaxy Z Fold3] atvxda:
Unlocked 512 Gig Fold3 in the US. I too am a bit concerned with my battery life and estimated battery health. My 1 yrld Fold2 had a battery health score of 96% whereas my 6 day old Fold3 has a battery health score of 88%

SOT with my Fold 2 up until last week was 5 to 6 hours with nearly 24 hours off of the charger. I'm getting 3 to just over 4 hours on average. On my best day I got just over 5 hours and on my worst day just over 2 hours of SOT. A little stumped🤔
[Samsung Galaxy Z Fold3] jackdforme:
Not sure this will past but anecdotally it's stabilizing now and seeing better battery only the last two days that's days five and six of new phone
[Samsung Galaxy Z Fold3] Mr. Orange 645:
Ugh...after a week, I'm seeing the opposite. Battery life is getting worse. 1.5hrs screen on time today and I'm down to 50%

Considering factory data reset and only downloading the necessary apps to see if something in the background is causing drain.

I'm hoping some software updates down the road will stabilize it too. My Note 20 Ultra got much worse battery life than my Note 10+ at first. Then a few software updates and it was rock solid too. I swear, both those notes were powerhouses that just sipped the battery.
[Samsung Galaxy Z Fold3] ycats:
Yeah, my Note-10+ was great on battery life.
[Samsung Galaxy Z Fold3] bs3pro:
LOL, What are people expecting??? We have a giant inner screen, AND an outside screen. Expecting ANYTHING close to your old normal phone is ridiculous.
[Samsung Galaxy Z Fold3] Acoustichayes:
He's right yah know. It's a 4400mah battery on a phone with essentially double the screen.

I however am getting 5-6 hours sot with dark mode enabled universally while on wifi.

I can say that the cellular power on these is really wonky. Not as powerful as many other phones and I think that causes some battery strain
[Samsung Galaxy Z Fold3] lawtq:
My main drain is Google service framework. Eating a ridiculous amount. After this is sorted in an update it'll get better
[Samsung Galaxy Z Fold3] Mr. Orange 645:
I'd just like it to be as good as my Z Fold 2...
[Samsung Galaxy Z Fold3] bs3pro:
Then you have a defective unit, or rogue app killing batt. Yesterday i got 4.5hrs SOT at max brightness. I am sure i could easily get 6 with auto brightness. That's pretty much what I expected with this beast.
[Samsung Galaxy Z Fold3] atvxda:
I was easily getting 5.5 hours of SOT on my Fold2, most times I was averaging 5.5 to 6.5 hours of SOT with nearly 24 hours off of the charger. My Fold3 is now getting anywhere between 4 to 6 hours max of SOT. Initially, it was getting 3.5 to 4.5 hours of SOT. I cleared all app cache and cut off my wifi scanning in order to get my current numbers. The point being, Fold3 was getting worse battery than my Fold2.

The higher front screen refresh and slightly smaller battery has some to do with it, however we were all expecting comparable stamina because of the new SOC.
