Normal is relative. Is it a bit on the low side? Most definitely. Normal? Maybe. It really comes down to the apps you have and how you use your phone. I personally get about 5hrs SOT and I'm fine with that. Standby drain is more important to me than SOT. There are battery saving tips and trick you can try to google or youtube.

My phone drains like 3% per hour on IDLE. I don't have AoD nor anything in particular that should be causing this drain. I have no idea why. The battery life seems to be fine for actual usage, but teeeerrible for AOD.

3% per hour no AOD is bad. You have an app causing major drain for sure. You might have to deep dive in your battery stats to find the culprit. Last resort would be safe mode to see if your able to reproduce the issue. You should go to the battery life thread and ask around.

I'm not sure what it could possibly be since my old Note 8 did this too, but it alternated every other cycle or so where it would drain less than 1% or 3%+. I exchanged it for a new one and this issue is happening again except it was completely fine for the first week or two. There was no app that I downloaded between the time that it was fine and not fine.
I guess I'll repost this in the battery thread.

i am not losing battery overnight as much as you guys, my problem now is i can't get 6-7hrs of sot anymore, 4-5 is as much as i get, and it's only 1 month old.

There was a thread about Android OS drain.

I miss my note 4. I use to get around 5-8 sot. With this phone only 3 and half hours. That's with everything turned off too. On my note 4 I had just about everything turned on. Will be waiting for the note 10 to release then I will buy the note 9

Is my phone battery dead?

I got my note 9 two months ago, I downloaded Accubattery today to check battery life then I charged it from 7% to 100%. I was shocked when saw that the battery capacity is reduced a lot! The app says it is now 3505mAh !!! With only TWO MONTHS OF USE !!!
Is that app accurate ?
I play PUBG a lot but that is why I bought the phone; because it is powerful and SUPPOSED to deal with that much of usage !!
I also use VPN all the time
I use 4G only no wifi no NFC no BT
When sleep for 6 hours with mobile data off .. standby consumption is about 2-3%/6 hours
Any suggestions ?

Read this topical about battery on Note9 and do not use any battery monitoring program. Erroneous readings.

Accubattery is your problem my friend, not your battery.
Enjoy your device, stop worrying that much about the battery.

Two hours of screen time presumably playing a video game most of that time, and still have 70% battery remaining. Iphone users would kill for that kind of battery life. Think about it, 2 hours of game playing gets you 30% battery drain, then I can surmise that you can play nonstop for around 6+ hours before your battery dies. That's excellent by any standard. I remember a time when 2 hours of screen time was considered decent, and that doesn't include playing a battery intensive gave. And that time was really only a few years ago.

It seems I'm over-concerned about the battery stuff.
Thank you all.

General Battery life experience

Hey guys,
So a month after the launch of the Galaxy S21 Ultra, what is your battery life experience? Give us your feedback and numbers.
Please mention your chipset (Exynos or Snapdragon) and post a screenshot if possible.
Personally, I'm pretty satisfied with battery life. I usually get a day and a half with around 9h of SOT. I have the Exynos model and my screen is set to 1080p with standard motion smoothness. Bluetooth is always on and I use 4G most of the time. All other settings are set to default.

How is you Phone radio usage so low. Mine is always way higher. Does that mean the signal is bad??

Can't complain, I get around 5 hours SOT a day with 30 to 40% left in the tank.
That said, I am stuck at home all day on WiFi, so sure that will decrease when I'm out and about with location on and 4g/5g but still pretty decent.
Exynos, QHD, 120hz, active 2 connected all day, some debloating and Bixby routines to switch to 60hz for some apps, turn off location/NFC/4g at home and sync/AOD on when charging

Standby for me has been amazing.

I think bad signal is definitely a factor. In my case, I stay at home most of the time (remote work) or at the office and in both locations I have a very good signal. Also my carrier doesn't support 5G yet, only 4G.

Ikr, even with Bluetooth on, I lose barely 3% at night.

Still on 91% I've been playing on my iPad all day so barely touched phone.

Had Exynos S21 Ultra that i didn't like the battery life of it. I had barley 4h of SoT.
I send it back to Samsung and got a Snapdragon HK version and i am getting 4.5h with the second full charging. I hope it gets better in a week or two.

Mine is amazing. Exynos. It keeps getting better.

I got the Exynos version.

Latest update made mine worse

It will get better. I was like you.
Then I reset my phone and didn't use smart switch and after couple of days I am getting now around 1h SOT per 10% with bluetooth and 4d enabled. Full resolution and adaptive framerate and sometimes I switch to 96.

Question Accubattery showing Battery health at 47% for a new phone (1 month old)

I purchased this about a month ago. I have been reading a lot of posts out here about people having fairly low battery life. So I had installed Accubattery to see if the discharge is abnormal. I checked today and it seems like Accubattery is claiming that my battery is only at 50~% health. Now I am unsure that if this is because it is a genuine fault or because this phone is supposed to have 2 2500mAh batteries and Accubattery is detecting only one of them. Any idea about this?

I've had my 11T Pro for roughly two weeks and I have the same issue.
It doesn't read charging speed correctly which confuses it's health calculations.
I'm sure your phone is fine.

Those SOT numbers seem erratic. Some reasonable, others look impossible.
When you're using the browser not watching vids the usage should low.
As the previous poster mentioned it may just not have good sensing for battery usage.
Accubattery is only as good as the data it's getting. Even then it can screw up. I don't understand what's going on there.
Rather strange. I don't have that phone so I don't know what it's nominal run time should be. If it's running cool and you can get 8-10 hours SOT you're probably in the ball park.

Hmmm, okay. I'll continue observing my phone's behaviour then. I do get over 8-10 hours SOT on medium usage. Additionally, I read from other threads that the 120W charger isn't charging the phone fully and it makes sense to charge with a lower power charger. So I will try that as well. Will keep this thread updated if I see any improvements.

Accubattery doesn't work well with dual battery setup, that's why it's showing Battery health at 47%.
Set design capacity to 2500.

11T PRO has 2x 2500mah battery for ultra fast charging. Set the design capacity to 2500 and you will be fine.

This presents a potential problem in the future as one battery can degrade and fail independently of the other. You really need to be able to monitoring both.
If the manufacturer designed it properly each battery should have its own power controller in a perfect world. Not sure if this is so on any of the dual battery phones...

Question Battery life of Galaxy S23

Hello, I am posting this thread because I am concerned about the battery life of my Galaxy S23 (SM-S911B/DS) (India). A lot of YouTubers and on social media too people are claiming screen time upwards of 5 Hrs. But I am getting around 4Hr only. I tested multiple times from (98-100)% charge to below (5-0)% and screen time is maximum of 4 hr 30 minutes. I am on latest software available current version s911bxxs1awbm. I am using single 4G sim (Jio 4G), with tap to show AOD, always on data/wifi, very less Bluetooth (up to 1 hr). Use mostly youtube, Instagram, telegram. 30-45 minutes calling. Adaptive refresh rate although I tried using 60hz but it had not that much effect on battery. Battery health is good. It barely lasts for 1 day. Please provide feedback…

I am getting around 5 hour 30 minutes. But, I am on permanent battery saver. Uninstalled / disabled most of the bloat already. Any tip will be appreciated! ( am on the Indian version too ). I remember my OP6T days, and custom roms were good for those looking for more out of their devices. I hope our device gets some ROMs as well..
Update- am getting 6 hour 30 Minutes+ when using deep sleep+ sleep options for apps I don't actively use. You might want to use it to get decent SOT. Battery could have been better from hardware side, but I think this is good considering the processing power of chip is good and camera is great.

the following is my experience.
I was getting even worse battery than this. battery life projection after learning usage for 3-4 days was 12 hours from 100%. i then took the extreme step of factory reset. also went to the service centre and got the full firmware flashed. they flashed the february firmware. i then set up my phone as new (without smart switch). i am now getting battery life at par with others. now i dont know if it was smart switch restore which was the culprit or the combo of that plus march update or just march update alone. but i am a happy camper now.

Still 15% left.

Same here, I got the S23 because I was fed up with the S22 battery life. Samsung offered me 650$ CAD to return the S22 so, I figured it was a no brainer. Still, I got the phone on march 28 and I get 5 hours of SOT at most. I'm a bit disappointed. Especially because I tweaked it to maximise battery life (I avoided SmartSwitch,I debloated, no AOD and I use Light performance mode). I did a factory reset today hoping it will finally bring real good performance.

I have constantly monitored the battery performance from the day I made this post. And found that when I use everything standard without compromising with the experience like AOD and adaptive refresh rate, Bluetooth etc. I can only get 4-4:30 hours of SOT. But with conservative use it easily crosses 5-6 hrs SOT. I think the battery is very sensitive to temperature also.

I had my doubts about this phone but, after my factory reset, all I can say is : I was wrong, my doubts were cleared. This evening, I was at 60% with 4 hours of SOT and 22 hours had passed since I last charged it. What kind of sorcery is this? I'm really happy to see those numbers. My old crappy S22 would be at 20% with a similar usage pattern.
