There is another thing you & all needs to check, not only enabling or disabling bands but to check the APN settings because incorrect settings could cause drops in speed.

I have this issue with my S20 Ultra (Snapdragon) that i imported from HK to Sweden, it picked up incorrect APN settings and i had like maximum speed of 50 mbit/sek over 4G. When i changed the APN settings, i could go up to 200 mbit.
[Samsung Galaxy S21 Ultra] braindamage90:
wow, 5G or anything else my signal is always at 2 bars (hate this carrier), is it possible this is the reason I'm getting no more than 4h SOT? even using just wi-fi. I did a fresh install, not a lot of apps, synced only picture and video with smart switch, disabled apps like chrome or smart switch, fhd+, brightness set to low always and 5g disabled. Exynos version
[Samsung Galaxy S21 Ultra] Mini Jay:
Even if you disable 5G the signal is still 2 bars ? Not more than 4h SOT that's pretty low, your phone is definitely working all the time to drain the battery so fast and that may have to do with that weak signal since your phone is constantly struggling to get you Network. Now combine that with an app that needs to sync regularly and yes no wonder why you have not more than 4h SOT. My bet is that if you have wifi on and your sim card disable from the network, your SOT will double
[Samsung Galaxy S21 Ultra] katolink:
Sorry for the (maybe) dumb question, but does eSIM instead of standard nano SIM while using 4G/5G have any impact on battery? Can eSIM cause more battery drain than nano SIM?
[Samsung Galaxy S21 Ultra] braindamage90:
this is exactly what I'm going to try, I'll write back in this thread if battery improves
[Samsung Galaxy S21 Ultra] speedyjay:
First of all, let just admire the retro Nexus wallpaper ❤️❤️

Secondly, after over a day, my battery is on 24% with 7.5hrs of screen on time.

Not bad going if you ask me...
[Samsung Galaxy S21 Ultra] Mini Jay:
That's great. QHD or FHD on ?
[Samsung Galaxy S21 Ultra] Mini Jay:
That's great. QHD or FHD on

That's great. QHD or FHD on ?
[Samsung Galaxy S21 Ultra] speedyjay:
QHD buddy.

I have taken drastic measures to get the most out of the battery though.

i.e Bluetooth is off, adaptive brightness, mobile data is off, GPS is off, auto sync is off, heavily debloated anything unnecessary for the safe and stable function of my device.
[Samsung Galaxy S21 Ultra] Mini Jay:
I get around 7-8h SOT at default settings, meaning FHD+ adaptive refresh rate, which is fairly enough for me.

But today I'm testing QHD resolution since I read an article that apparently assume that the adaptive refresh rate save more battery in QHD than FHD mode.

By the way I notice absolutely zero difference between FHD and QHD even when watching videos on youtube. God sake I must be either blind 🤣
[Samsung Galaxy S21 Ultra] mysterioustko:
One more battery life update (Snapdragon).

1hr of talk time, 7.5 hrs of screen time

FHD+, Adaptive display

Battery lasted a little over 24 hours.

Not bad at all.
[Samsung Galaxy S21 Ultra] Ereckson:
So everyone who's getting screen on time of over 6 hours is using the phone mostly on WiFi. I can squeeze out maximum 6 hours of screen on time. This would be on 5G with 3 hours of video playback, an hour of video calling and an hour or so of web browsing. Also the phone would be connected to bose qc35 ii for most of the day.
[Samsung Galaxy S21 Ultra] mysterioustko:
I have tried comparing the two as well. I THINK I might notice a difference if I try hard enough to notice, but it could also be placebo.
[Samsung Galaxy S21 Ultra] Mini Jay:
That's my point, if the difference is barely noticeable then QHD isn't worth it.

BUT, I have a pretty good battery life with QHD so far, even wondering if it's better than FHD thanks to that adaptive refresh rate that seems less power consuming than FHD for some reasons.

So if that's the case, I stick with QHD resolution. But not for the resolution since it isn't dramatically better (still don't see how better it is by the way).
[Samsung Galaxy S21 Ultra] mysterioustko:
I tend to agree with you on the significance of QHD. I have only tested the battery life on QHD for a day, and that was when the phone was still getting acclimated. I'll try QHD tomorrow and see how it goes.
[Samsung Galaxy S21 Ultra] ac42:
I'm getting crazy good battery life on the SD unlocked, 120hz qhd. Easily a day and a half, with 8 - 10 hour sot, and usually charge when I'm down to 20%. I've never had a Samsung phone that performs as well as this.
[Samsung Galaxy S21 Ultra] mysterioustko:
I ran today on QHD on adaptive. I did a lot more talk time today than yesterday, but I still got a little over 21 hours of battery life with 8 hrs of talk time and 4 hours of screen.
[Samsung Galaxy S21 Ultra] Mini Jay:
Let us know. I can't tell if the battery life is better because of my usage patterns has changed of because my phone optimized the battery but

Nice. I'm sticking with this QHD, the battery life was surprisingly very good yesterday
[Samsung Galaxy S21 Ultra] mysterioustko:
So I've been watching my battery use intently since I got it. For the first day or two it wasn't great, but I hadn't bothered to really set it up in any optimal way. I'm not one of those people that turn everything off to get good battery life, because to me that defeats the point in getting a phone that has great capabilities. I did turn off nearby device scanning, and made sure to limit facebook and instagram and turn off their auto update inside the app (that by itself makes a big difference). It's also worth noting I have adaptive power saving turned off. After that, I had some pretty solid battery life, but it was still "learning my usage pattern". I eventually got the message that said it determined what apps to put in deep sleep. About two days later it put those apps to deep sleep and it showed an estimated battery life instead of saying it was learning my usage pattern. At that point, my battery life took a jump. At this point, I can use my phone pretty much however I want, and not touch a charger all day. Interestingly enough, now that my battery life has started pushing the 24 hour mark, my phone has gone back into the learning my usage pattern, on it's own. Hopefully when it finishes again, I get another battery life jump lol.
[Samsung Galaxy S21 Ultra] nightoooo:

[Samsung Galaxy S21 Ultra] pro_hvtc:
I really love s21 ultra 5g. I am using full funtion, wifi always on, 4g on, dual sim, play games, zalo.....i thinks 2100 exynos is the best exynos

Spoiler content hidden.
[Samsung Galaxy S21 Ultra] nightoooo:
Which apps (besides FB & Instagram) do have auto update inside itself? Would be great to share how to turn these auto-updates off?

Thanks!
[Samsung Galaxy S21 Ultra] mysterioustko:
Update:

Since my phone went back into the learning my usage, it has learned again. My battery life has taken another jump since it finished learning the first time. 28 hrs of battery, 3.25 hours of screen time, 7.5 hours of talk time. I'm more than satisfied now. I'm confident that with light usage, I could go two days on a charge.
[Samsung Galaxy S21 Ultra] russellcausier:
Been brilliant on exynos so far!!way better than the 990!!that was a massive let down,although using a few tweaks like the galaxy hz mod,and power saving mode with 96hz and wqhd+ and few ads commands got rid of bixby and Facebook services,still shouldn't have to do all this but is amazing with these tweaks,most apps in deep sleep having only social media and others I need notifications for in sleep mode.
[Samsung Galaxy S21 Ultra] VoidedKN0X:
wifi, 4G, dual sim with bad reception, location, 120hz,1440p and power saving mode

Must say i can't complain coming from an s9+ that has been used for 3 years
[Samsung Galaxy S21 Ultra] Quazza:
Any tips on said tweaks would be appreciated
[Samsung Galaxy S21 Ultra] russellcausier:
Search galaxy max hz app in these forums puts lockscreen to 48hz to save battery and can also go 96hz too,also on forums in here is an adb list and stuff to remove Bixby and bixby wake as never use them and Facebook services is apparently a massive drain,the phone hardly drains when not used,check sakitech on YouTube should be a video for the power saving trick it's on s20 ultra but works for this even with qhd
[Samsung Galaxy S21 Ultra] Quazza:
Will check it out. Didn't use my phone a ton today. Around an hour of screen time. AOD was showing as the largest battery drainer
[Samsung Galaxy S21 Ultra] russellcausier:
Yeah apparently that takes a decent percentage per day does aod, never use it anyway myself
[Samsung Galaxy S21 Ultra] westeight:
Exynos, WQHD+, Adaptive, mixture of 5G and WiFi.

I'm now in week three with the February update and the battery keeps improving:
[Samsung Galaxy S21 Ultra] nightoooo:
I guess if u disable 5G, you will have at least 30 mins more SoT.
[Samsung Galaxy S21 Ultra] carlitobahsoun:

Exynos, Bixby routine running for 'power save mode' at night and at work. 7hr screen time and overnight standby with 24% left. Cannot complain.
[Samsung Galaxy S21 Ultra] sswagonman:
Did u restore anything from Samsung account backup?
[Samsung Galaxy S21 Ultra] mzsquared:
That's more like it! That's what I'd expect from a big 5Ah phone battery.
[Samsung Galaxy S21 Ultra] Elhombree:
I got my device 2 days ago and my first cycle was yesterday where I started the day att 7 am and ended roughly 01 am. I had 15% battery left and got around 7h 55min SOT in my first cycle. AOD, location etc on. Also have adaptiv battery and adaptiv motion with FHD resolution.

As days will pass i think battery will improve further. Today I will test without Aod. I am very satisfied so far.

Quick notice that this device gives me crap cellular connectivity. I have ordered a new SIM card, hopefully that will fix it. I dont know if any of you have had the same issue or not.
[Samsung Galaxy S21 Ultra] karandevilocs:
Has anyone got a day of battery life with HIGH USAGE OF CAMERA ?

i get around 7hrs of SOT in normal usage (after lots of optimizations and updates) but whenever i start to use the camera i can see that battery deplets way faster than usual

can anyone get around 7~8hrs of SOT with taking high amount of pictures / recording vids?

I'm on AUB9 in 512/16Gb Exynos Variant !
[Samsung Galaxy S21 Ultra] osmosizzz:
Crazy to see what you guys are getting battery life wise. Today I got 22hrs run time with 5.5hrs screen on time. Thought that was alright but seeing 7+ hours and over 26 hours, seems mine is under performing. I have the SD variant. Seems also that the exynos is back. Much better battery life overall than the snapdragon. I just Uninstalled smart things and put a bunch of apps to sleep. The apps I use on a daily basis, like Instagram, Facebook, snapchat, Chrome and YouTube Vanced are still not put to sleep.
[Samsung Galaxy S21 Ultra] osmosizzz:
Any updates? Snapdragon T-mobile here. Came over the forums to see if battery life could be better as this phone has a massive battery and was barely outpacing my S10. Looking into what to do with mine and seeing if a factory reset and no smart things restore would do the trick
[Samsung Galaxy S21 Ultra] Tondern:
I've got the Exynos version and have been super happy so far. Actually I can't believe how little the battery drains when watching videos. A 45 minute Netflix episode in QHD drains about 4%. I always run QHD and adaptive refresh. This is my latest SOT with 7% battery left.
[Samsung Galaxy S21 Ultra] abhi021:
Which firmware you are on?
[Samsung Galaxy S21 Ultra] NeidRider:
I'm seeing terrible values, never get more than 18h out of my phone with 2h SoT.

Got in contact with Samsung, they say it's a known issue and to be resolved in an upcoming update.

Yeah, sure...
[Samsung Galaxy S21 Ultra] Zaxarive:

[Samsung Galaxy S21 Ultra] nightoooo:
Snapdragon S21 Ultra

Mixed usage between 4G & Wifi

It can easy get 6-7 hours of SoT with heavy usage..

QHD+Adaptive 120hz

For now

53% left of Battery life

3.56h SoT

18.42.h since last charge

No optimization at all, everything is on by default.
[Samsung Galaxy S21 Ultra] Algraham93:
Hi guys, my battery drain is terrible, averaging around 4 hours SOT and that's without playing games... any ideas?

Running FHD, adaptive brightness and 120hz adaptive..

Thanks!
[Samsung Galaxy S21 Ultra] Jostian:
I'm at 9 odd hrs SoT, but i have debloated a bit, 5g off (eats battery looking for 5g) also data off as I'm in WiFi zone 95% of the time, most apps i don't use often are in deep sleep. Adaptive refresh rate, very happy, coming from now 20 Ultra (which i loved) but the battery was at least 30% worse in terms of SoT and standby times.
[Samsung Galaxy S21 Ultra] 80s Baby:
did you debloat it using adb or twrp?
[Samsung Galaxy S21 Ultra] Jostian:
I used this tool (ADB) https://xdaforums.com/t/tool-adb-appcontrol-v1-6-1-app-manager-debloat-tool-for-android.4147837/
[Samsung Galaxy S21 Ultra] carlitobahsoun:

sync off , bluetooth on , location off
[Samsung Galaxy S21 Ultra] Jostian:
I'm very happy with my SoT, see screengrab.
[Samsung Galaxy S21 Ultra] :
Any tips? Mines been bad lately and factory reset did nothing.
[Samsung Galaxy S21 Ultra] Jostian:
I debloated a bit, don't have 5g activated (eats battery looking for 5g), only have WiFi on not data unless not in wi-fi area. Went through apps list (including system apps) and disabled background data and battery usage, also put apps i don't need it use into deep sleep or sleep mode. That helped quite a bit.
[Samsung Galaxy S21 Ultra] Quazza:
3 days ?! 😳😳😳
[Samsung Galaxy S21 Ultra] Jostian:
I've had 4 days but then SoT is only around 7 hrs as i lose some to standby time.
[Samsung Galaxy S21 Ultra] Quazza:
Still incredible man. I get a day, max
[Samsung Galaxy S21 Ultra] Patrick9801:
I usually get 7h of SOT. Pretty good in my opinion after switching from an S9 with only 4h SOT. Exynos, 120Hz, WQHD+ all the time, WiFi mostly, BT/NFC/Sync/AOD/Location/Battery Saving Mode always off, Dark Mode 80% of the time, brightness mostly at 75%. I also disabled some apps with Package Disabler Pro but I'm not sure if it brings that much improvements.
[Samsung Galaxy S21 Ultra] LSS_52:
Looking at some of the battery life most of you are getting definitely makes me think I've got an issue with my device.

I'm having to charge my phone in the middle of the day, had it for over a month now and it's been like this since day one. Am I charging too often?

Any help or advice would be much appreciated!
[Samsung Galaxy S21 Ultra] Bidyadhar:
Avoid using Chrome. It's a battery hog on s21 ultra. I had to switch to Samsung internet due to the same reason
[Samsung Galaxy S21 Ultra] Jostian:
A few things to try, make sure data connection is not on 5G (i disable data 80% of the time as i have WiFi), make sure you have put apps you don't use into sleep or deep sleep. Then make sure you go to setting, apps (show system apps) and disable background data and battery use for apps you don't use often. Set adaptive refresh rate to on. Debloating a bit always helps. There is more to try but if you try the above and you don't see a noticeable improvement then we'll try something else.
[Samsung Galaxy S21 Ultra] Jostian:
I use Chrome but have it set to sleep, with no background data or battery use, and it's battery impact is way better.

See screengrab again, just over 6 hrs SoT over more than 2 days with 32% left, so will probably get to 9 odd hrs SoT over 3 days or so. Which means if i used my phone more intensely over a day or so if probably be around 11 to 12 hrs SoT, which is great.
[Samsung Galaxy S21 Ultra] mtm1401:
Firstly get rid of chrome (it's broken), use Samsung internet as it's way lighter on the battery.

It looks like something is stopping your phone from sleeping on some of those graphs, chuck everything you don't need to deep sleep, or install something like GSAM that can tell you what's keeping it awake
[Samsung Galaxy S21 Ultra] :
I'm not impressed 😐
[Samsung Galaxy S21 Ultra] Kharn501:
Not sure if this will work for everyone but I decided to play around and change background process limit to 4 in developer options just to see what it would do. Anecdotally I'm seeing a pretty noticeable gain.

I'm WFH full time so my phone is almost always on wifi only but location off and all the battery saving mode/optimization features turned on. I also am using 60Hz refresh and FHD+.

Previously id usually get about ~2 days out of a battery this way but I'm on day 3 and still have quite a bit of battery left. I haven't gotten any firmware updates or uninstalled/changed any apps. Attached a second screenshot from a few days ago before the change to show the difference.
[Samsung Galaxy S21 Ultra] ephumuris:
I don't think I have even managed 6 hours SOT so far. I have AOD on, highest res setting and adaptive refresh rate on too. Exynos device I'm pretty disappointed with it overall.
[Samsung Galaxy S21 Ultra] aj7400:
Same situation here , I barely manage to get 5-6 hours of sot with 1440p + adaptive + aod always on. ( no gaming or heavy tasks)

I am on 3rd day of my phone ..

May be with time it gets better .
[Samsung Galaxy S21 Ultra] TheSkyline35:
For now I'm on the same boat.

Exynos model here. 4th day with the phone, it's currently absolutely bad for such a big battery and expensive phone.

Around 3h SOT yesterday, I was quite mad about that. No gaming, nothing intensive, but QHD 120HZ, (Well, I paid for those features so I want to use them !) and dark mode only by night. I applied all the classic optimisation stuff for apps, not even using AOD.

Maybe it will settle with time, I also find the phone phone bit warm...for now It's a big let down at that price.

Today I'm at 70% for 1h30 of SOT, it's better, but very far from what I expected with such a big battery. Again, maybe more time is required.

[Samsung Galaxy Note 10+ Guides, News, & Discussion] :
Hi everyone:

I have the Samsung note 10 plus with the Snapdragon chip and before the most recent update (version 11), I was able to access with rootbrowser my system files, particularly my playercorefactory file in internal storage/android/data/kodi/userdata. Most folders are empty now.

How do I regain access? What are my option? I can't seem to find a bootlooder un-lock in developer's options, and it's been well over a year since I opened it. I have Android studio installed and some adb drivers. Not sure how to proceed. Need help "please".

Did root my note 3 and modified my build.prop when I installed Viper, so I have little bit of experience. Also, did some Java tutorial and Android Studio tutorials, so if I recall things can be modified through main.manifest.

I know you guys are all busy, so any insight or guidance you can provide would be greatly appreciate it.

In the settings, keys, there is only button 1 (hold) shown, nothing else.
