I've heard lots of maybes, but maybes isn't enough... I had it for 3 months and it wasn't fixed during that time. I had 3 devices as well all with the same issues, and it got returned in the end. Thought the S21 would be better, which the display is, but the battery is awful unfortunately.

S20 FE 5G battery was amazing compared to this, I rarely charged before I slept but at the moment I'm charging this phone by 6/7PM
[Samsung Galaxy S21 Questions] joakimbo:
I had the S20 FE 5G myself. Switched it for the S21. First week I was really impressed with the S21. Much better feel than the S20 FE 5G imo. Battery life was also close to what I got with the S20 FE.

But the february update completely ruined this device. I'm hoping Samsung announce their aware of this issue or at least fix this in few days.. Cause I can barely use my S21 right now. I'm out of battery during a workday.
[Samsung Galaxy S21 Questions] Kabforks:
My temporary solution was to disable 4g and 5g while at work or while at home (where you have Wifi).

I went into Settings - Connections - Mobile Networks - Network mode: select 2G/3G. I think this will disable 4G and 5G letting your phone rest. Of course... remember to turn back on while on the go.

See my battery with this setting. Red = 4G/5G enabled. Green = 4G/5G disabled.

Let me know if this works for you guys. Of course this is not sustainable , so consider what's important before changing.
[Samsung Galaxy S21 Questions] NolanBart:
Yes, after setting 3g/2G mode the power consumption gets better...
[Samsung Galaxy S21 Questions] Threshold-1:
I also went from FE5G to S21. Initially (separate photo in advantage for FE) the battery life did not make me regret the change. But now with the latest update I can't get past 5pm! That's 1000 euros of smartphones, I hope Samsung will take serious and quick action.
[Samsung Galaxy S21 Questions] joakimbo:
It annoys me when I see people saying that they don't notice anything. It has to be universal? All base S21 Exynos models. Unless there is some settings that affects that this is getting triggered.
[Samsung Galaxy S21 Questions] fBx:
It seems to be a modem problem. Multiple people on my german board report back that if you set your phone to 3G/2G only (=disable 5G and 4G), the problem is gone and I can confirm that, I tried myself.

This is not the time to return any phones, set up lawsuits or, god forbid, continue to complain online - but to just accept that it is a firmware bug.
[Samsung Galaxy S21 Questions] Finners:
Same problem here and it does indeed seem to be fixed by setting 3G and 2G only.

I've sent an error report through the send feedback option on the Samsung members app that includes a log file from my phone, Hopefully if enough people do that it will at least be going through to the correct people at Samsung to see it.
[Samsung Galaxy S21 Questions] JCMate10:
Naa... I would imagine Samsung testing basic stuff like that... Everyone is in guessing mode (myself included). Report it to Samsung and return the phone. You cannot know for sure that it will ever be fixed. It is too expensive to leave around as paperweight.
[Samsung Galaxy S21 Questions] joakimbo:
I tipped the two biggest tech news sites in Norway about this issue. They actually posted article on this matter. They've been in contact with Samsung today, and Samsung said they are aware of the issue, and working on an update.
[Samsung Galaxy S21 Questions] JCMate10:
Awesome! By interest, could you post link to the articles? Would like to read them. Thanks allot!

Galaxy S21 har fått batteriproblemer etter oppdatering - Tek.no

Både lesere her på Tek.no, samt brukere på Reddit og diverse andre fora, melder om at batteriet på Samsungs mobilflaggskip Galaxy S21 nå tappes unormalt fort.

[Samsung Galaxy S21 Questions] JCMate10:
Thanks!
[Samsung Galaxy S21 Questions] =dave=:
Thanks man!
[Samsung Galaxy S21 Questions] luke_c94:
Having lived through the S20 FE display issue saga, what I'll say is if you're not happy with the phone by the time your return period is up, then just return it. You can always buy it again later. They was 'aware' of the display issues for months, and 3 months later, with multiple updates promising fixes it never was completely fixed.

Not saying it will be the same here, but don't place all your trust in them.
[Samsung Galaxy S21 Questions] blinkin:
Enabling 3g seems to solve battery drain. Samsung better fix it soon. I've sent the error over Samsung members
[Samsung Galaxy S21 Questions] inffy:
There will be software update to fix the battery drain (atleast on the S21 that is affected). Depending on the region it will be available soon, on the Nordics it was said that propably next week.

Definate timeline for the release is not yet known.

This is straight from Samsung (nordic)
[Samsung Galaxy S21 Questions] ikbenben201:
I've tried to notify the drain trough the Samsung Members app but I got a standard answer. "There seems to be a hardware problem" but I specifically said it occurred after the February update.

Useless :rolleyes:
[Samsung Galaxy S21 Questions] =dave=:
always the same stupid answers from people who have no idea what they are talking about. I wonder why they even get hired.
[Samsung Galaxy S21 Questions] ikbenben201:
It's pathetic, why did I even bother.
[Samsung Galaxy S21 Questions] gian1989:
I can confirm that setting 3G/2G stops the battery drain. At least while waiting for the fix we have a solution. Yesterday I went to sleep with phone at 30% and this morning it was dead. :mad:
[Samsung Galaxy S21 Questions] skyline91:
I've also send error report and i've got reply from them that i should try safe mode to see if it's some app and if that doesn't help that i try to do the factory reset.
[Samsung Galaxy S21 Questions] =dave=:
it's freaking pathetic how clueless they are. really thinking about returning the phone
[Samsung Galaxy S21 Questions] blinkin:
After setting 3g
[Samsung Galaxy S21 Questions] fBx:
There's two ways to work around this issue for now - either go 2G/3G only for the moment or just grab your previous firmware from sammobile and flash it via Odin (i.e. downgrade to the previous FW that didn't have that bug). If you use HOME_CSC instead of CSC, it won't wipe your data. Pity that the download is so slow, otherwise this would be a matter of minutes.
[Samsung Galaxy S21 Questions] Didgeridoohan:
Moderator comment:

Yes, there was an off-topic S21 Ultra question in this S21 thread. That's absolutely no reason to be snarky towards a new member that happened to post in the wrong forum. Try to remember that everyone's a noob at some point. Better to help than berate...

Some light cleaning had to be done.

Galaxy S21 February security patch is reportedly causing battery life issues

Galaxy S21 February security patch is reportedly causing battery life issues

A fair number of Galaxy S21 owners are complaining about poor battery life on Reddit and a few other forums, ...

www.sammobile.com
[Samsung Galaxy S21 Questions] Bazim:
Guys, my 14 old days S21 with last update (i think it was on the 8th of February) is in really bad shape. Look at this screen. 10h with 1h 15m SOT and 40% battery.
[Samsung Galaxy S21 Questions] fBx:
@Bazim

I truly recommend reading this thread.
[Samsung Galaxy S21 Questions] blinkin:
3g really makes a difference but I want my volte back!
[Samsung Galaxy S21 Questions] JCMate10:
Seems better, but still, you have less than 2 hours SOT. So, with 4 hours SOT it would most likely be dead now - and 4 hours is really not allot :(
[Samsung Galaxy S21 Questions] HugePotato:
After setting 3G only, I have the phone unplugged for the last 22 hours with 1 SOT and 1 Antutu benchmark run (which took few percents off the battery) and I'm at 70%. Edge browser also says it worked in the background despite setting it to deep sleep. Removing it would probably yield even better battery life, I have to find a better browser. To be honest I didn't get battery life this good before the update. That LTE module sure is energy hungry, even before the update screwed it up.

Update for S21 and S21+ rolling out via OTA -- "AUB6"
[Samsung Galaxy S21 Questions] fBx:
Seems I was right after all. Who would have figured.
[Samsung Galaxy S21 Questions] FROGMaaster:
Yup, new update is here. Installing 🤞
[Samsung Galaxy S21 Questions] Kabforks:
You must be fun at parties. Are you always this condescending when talking to people?
[Samsung Galaxy S21 Questions] Pierre58000:
Hello all of you talk about an update to correct the February have you a link because in the parameters of my phone no possibility thank you to you
[Samsung Galaxy S21 Questions] HugePotato:
Well he quoted himself. Some people here suggested that no update will ever be rolled out to fix the issue. Now we just have to see if it was fixed.
[Samsung Galaxy S21 Questions] JCMate10:
I would like to see consistent SOT, more than 3-4 hours, before accepting this. Even before the update that made battery life bad, it was actually not very good.
[Samsung Galaxy S21 Questions] hanniSK:
Everything is OK after today update. S21 5G Exynos version.
[Samsung Galaxy S21 Questions] FROGMaaster:
Update is rolling out via OTA, so certain number of devices at a time. Eventually you should get it. I just clicked "check for system updates" in settings and it was there. I'll test it overnight and see how it goes.
[Samsung Galaxy S21 Questions] luke_c94:
I have the update and it seems to have fixed the battery drain
[Samsung Galaxy S21 Questions] Pierre58000:
I'm in France and my phone tells me that I'm up to date with this update G991BXXU1AUB3 C IS the last because it offers me nothing more recent
[Samsung Galaxy S21 Questions] FROGMaaster:
OTA works like that. Until your device gets to pool of eligible devices, it will tell you that you're up to date. Though notification about available update can come with some delay, so you can check for updates from time to time if you want it asap.
[Samsung Galaxy S21 Questions] Pierre58000:
ok thanks i waiting
[Samsung Galaxy S21 Questions] joakimbo:
NEW UPDATE OUT! People saying it fixes this issue
[Samsung Galaxy S21 Questions] Levisaurus:
Still on the G991BXXU1AUAB update here in Croatia, but the battery life was crap since i received the phone on the 25th last month, switching to 3G yesterday helped a lot though
[Samsung Galaxy S21 Questions] blinkin:
updated, 5g activated, let's see
[Samsung Galaxy S21 Questions] ikbenben201:
Got the update after searching manually. Belgium btw.
[Samsung Galaxy S21 Questions] Pierre58000:
hi you have find or this update has you a link or a site or find it thank you
[Samsung Galaxy S21 Questions] Finners:
Received the update today in the UK, Hopefully its sorts out the battery. To early to tell atm

I think he means search manually on the phone go Settings>Software update>Download and install

This will make the phone search for the update
[Samsung Galaxy S21 Questions] destz0r:
Battery drain seems to be fixed with this new update.
[Samsung Galaxy S21 Questions] HugePotato:
I can tell that it fixes the issue. After 8 hours 30 minutes and 1h40min SOT I'm at 72% battery. I have the LTE enabled but I'm using WiFi along with VOWIFI. In the same conditions I would have lost probably 50% battery. We will see how it does overnight but it's looking fine right now
[Samsung Galaxy S21 Questions] blinkin:
With 5g the drain is smaller than before but still not super good

5g?
[Samsung Galaxy S21 Questions] HugePotato:
Ah well I don't have it enabled as it's basically LTE on steroids but at the same time I'm on WiFi so it wouldn't connect anyway. Also I don't have mmwave in europe and a data plan that is throttled to 20 mbps but unlimited so no difference for me.
[Samsung Galaxy S21 Questions] blackhawk:
Basically sums up the intelligence of power management.

It gets more inept the more you use it...
[Samsung Galaxy S21 Questions] blinkin:
Not so great... I enabled 5g after the update at around 45% 😱
[Samsung Galaxy S21 Questions] blackhawk:
Try clearing the system cache and reset network settings.

Make sure a cloud apk isn't going nuts in the background. I don't let any run.

Goggle Play Services polls the internet 4 times a minute on my 10+; firewall blocking it helps improve battery life. Karma Firewall uses little battery.

Try ditching WhatsApp... it's crapware.

After a major firmware update a factory reset is best. Otherwise it probably isn't a good plan.
[Samsung Galaxy S21 Questions] Romi14:
This is my battery life. I came from S10e exynos version. S10e is known to have bad battery life, but S21 is clear winner here. Terrible battery life. Probably worst of all phones I had since Xperia Z1.
[Samsung Galaxy S21 Questions] blackhawk:
Tone down Messenger and Goggle Play Services; they're eating up your battery life.

That's not the CPU's fault...
[Samsung Galaxy S21 Questions] mzsquared:
I think am getting a really good results on my 21U batterywise. Nothing conclusive yet, am taking it slow. Did a major de-bloat first, removed sim and I ran the phone like a wifi tablet to see if I have any bad battery bleed, all was good, kept idle on airplane mode for 20 hrs and it only dropped from 100% to 92%. Now I got the sim back in, but @ 60Hz and it's still looking good. When I use up current battery load I'll switch the screen to 120Hz, will see, but I'm now convinced more then before that it's a keeper. I bougt the phone for the camera anyways. Uh, AOD is switched OFF on the phone not by adb.
[Samsung Galaxy S21 Questions] joakimbo:
Have you checked for the new update? February update ruined the battery life. Read tech blogs like Sammobile. I'm back to facing 6 hours SOT in 24hrs instead of having same as you have now.
[Samsung Galaxy S21 Questions] blinkin:
Thanks for the tips. I reset the network but don't think it helped much. I think system cache is reset after every update, that's why all the apps are optimized during startup but I might be wrong.

I'm not going to factory reset this phone 3rd time within 2 weeks. I'm also not going to stop any services in the background. Same setup on p30 pro I was getting 7-8h sot and 2 days standby.
[Samsung Galaxy S21 Questions] destz0r:
Firstly, are u on the second february update which was released yesterday? Or still on the first one? If you're on the first one, update ASAP! The newest update from yesterday fixed all battery problems for me.

Secondly, ur messenger eats too much battery, and so does your chrome. Try to use another browser since chrome is known to have high battery usage with the S21.

Thirdly, Google Play Services only uses around 2% for me. You can fix high GooglePlayServices battery usage by following this video (worked for me before):

After the newest february update, im getting MUCH better battery life than my previous S10e exynos. I fully charged my phone ~21hours ago, and i currently im at 5h16mins SOT and still 32% battery left (half of the time i was on wifi, other half on 4G, bluetooth+location+AOD+120Hz always ON). So i can easily reach 7-8hours SOT.
[Samsung Galaxy S21 Questions] fBx:
If it is well deserved, like in this case - of course. Got called out for BS and unbased claims and woosh - there the bugfix comes. Welp. Time to scram.

Depuis ma dernière charge à 100% je suis à 17h29mn pour 78%.

Et il m'annonce encore 1 jour et 8h d'autonomie restante. Je suis également en AUB6 mais sans être passé par AUB3. 😉

Je trouve mon autonomie au top.
[Samsung Galaxy S21 Questions] Canard caché:
I don't invent it: I showed the result with a screenshot. I don't know the issue but cleraly ther is one.

For example: I sleep with sound players on my phone.

Before update => 8 h sleep = 7% battery.

After +> 8h sleep = 35 % battery !
[Samsung Galaxy S21 Questions] destz0r:
Well, there's a newer update (AUB6/AUB7) which fixed the battery problems. You are still on the version which has battery drain.
[Samsung Galaxy S21 Questions] Canard caché:

[Samsung Galaxy S21 Questions] skyline91:
Yesterday i factory reseted phone, but battery life is still bad. AUB6 didn't help, i'll try to disable volte.
[Samsung Galaxy S21 Questions] xdafly:
Has anyone else done changes using ADB AppControl Extended version and turning off some system apps ? This appears to help battery life as there are quite a lot of items that I never use but that consume battery as reported by CCleaner Pro 5.4.1 > Apps > Drainers > Battery

I also changed Location and WiFi settings not to keep constantly scanning and more (there is a YT video that was posted on XDA previously and I picked up ideas from youtu.be/hxDawTMnwCU?t=11 )
[Samsung Galaxy S21 Questions] blinkin:
Which apps are these?
[Samsung Galaxy S21 Questions] xdafly:
As I do not use any social (anti-social) apps, have disabled (not deleted) all of them. Also disabled all Samsung apps, tweaked location & wifi and changed Sync settings as explained in the YT video.

Disabled almost all of carrier (ATT) apps.

An easy way is to turn off one item at a time and observe for a day or less to see if any real functionality is missing or not working as expected. ADB AC Extended allows you to set/unset/restore as you wish and I even deliberately disabled some system apps just to see if I could lock phone or recover (recovered! nicely)

A fingerprint is essentially just a print left behind on any type of surface due to the oil on our skin.

AFAIK fingerprint scanners are designed for a certain level of oil on our skin; if a person's skin is dryer than that, they don't work.
