Note 20 Ultra (Exynos version) - Big battery draining issue - Samsung Galaxy Note 20 Questions & Answers

Dear XDA members;
So, I've bought note 20 ultra a few weeks ago (refurbished, great condition!)
I've switched from Galaxy Fold 1 and from what I'm seeing, the battery life is almost 2x more horrid!
I've been trying to use it in order for it to get adjusted to my patterns, still, nothing special happened after weeks of usage.
I've tried everything - naptime + turning off adaptive battery; turning it back on and deep sleeping the apps, changing the settings for maximum battery life etc. Wiped the cache and reset my phone, still nothing. NOTHING helps!
I've even decided to buy a new battery! My battery life is still horrible. Based on the reviews, I should be getting decent battery life, however, it is about 2.5-3h of SoT... Idle battery drain is also insane...
I'm using android 13 and I've noticed that a lot of people seem to write that it's the problem.
Does anyone have any suggestions? Should I install some custom rom? If so, which one would you suggest?
I REALLY love this phone and I REALLY want it's battery to last for at least 4-5h of SoT...
Thanks A LOT in advance!
Best regards!

I think sadly that's normal for the Exynos phone. It was always the thing fro me, I've had it since November 2020. My screen and battery were changed a month before the 2 year warranty ran out, and with a new battery I still get around 2-3 hours of SOT

3h sot is ok!I still have ny N20 but iḿ using a Google Pixel Pro,new!and 3 h ,perhabs a little bit more is what it gives!I will keep my N20 ;its a mess what Samsung is doing!And this for many years!For example;my Note 3 or my Note 4 were wonderful Phones,realy!With new Baterys they can do a good job ,eveb in 2023 with Androis 13,they give **** of this!And so i quitt Samsung,leider!

Battery life is great

I'm really impressed by the battery on the A7. I've had 3.5 hours of sot and 20% left even after caning it with DS Audio, 4 hours of internet radio, 50 photos plus editing and lots of surfing.
Doze is extraordinary. Check out last night's battery consumption (I really must get to bed earlier).
Best battery life on a phone that I've had so far.....Well, since smartphones. I had some flip phones that could last a week.
It seems to be a bit better than the Nexus 6P I came from. Definitely not as good as the Oneplus One, much better than the Moto X Pure.

The main thing I've noticed is that this phone doesn't get excessively hot which seems to kill the battery very fast (both issues I've had with almost every smartphone owned: Nexus 6p and Oneplus One included). Apps that use GPS, camera use, gaming etc don't seem to get the phone as hot and this seems to correlate with better battery life under use. The only time I feel the phone warming up is if I'm using the Quickcharge charger while doing something else. It's barely warm though.
If I babied my Oneplus One (Sultans ROM) I managed to get 8 hours SOT which was crazy but it didn't charge the way the Axon 7 does and it certainly wouldn't have coped with the stress I'm putting on the Axon 7. I remember things like constant GPS + Spotify + Bluetooth would mean my Oneplus One wouldn't be able to charge as fast as the battery was being drawn. Not an issue at all with the Axon 7.

I agree on all points. This is one of the coolest running phones I've ever used. Only thing I've done that creates noticeable heat other than charging is +30 minute phone calls on Bluetooth in car. And it charges unbelievably fast. Very happy!
Got ,5 and a half hours yesterday. I honestly average 5 hours. Battery life has improved significantly with this smart power voodoo on. It doesn't affect performance unlike it does on tw.
I notice more apps are closed in background when I have smart power on.. Like I'll be able to have about 5-10 apps open with smart power on.. But 15-25 with it off.
I get an extra hour sot with smart power on.
And I took quite a few pictures that day.. Totally thought I was going to toast my battery.. But it held up better than any of my samsung devices..
The Axon ZTE 7 A2017 has the most smart power!!! I dont have to worry for the whole day charging my Monster!!!
I agree with all the comments here the battery is really good, pair with fast charging if necessary is a winner !!!!
Same here I'm enjoying the battery life on this bad boy!
I would also say it's not too bad.. still 25% remaining after 5h DOT
Agree! On at 6:30 am and still at 86% - light use. 1 phone call, a few texts and 10 or so minutes checking the news. My note would have been 70-75% by midday with about the same use. Power save mode on both phones. Very happy with this phone.
I started this thread and I'm still pretty happy with the battery life but this evening I noticed the phone was a bit hot. First time I've noticed that. It drained from 45% to shutdown in 10 minutes. This is what my Oneplus One used to do. How can the same sh*t happen to the same guy twice?

Sounds like you've got a rogue app in three background that's forcing your CPU to max out and keeping it there even when not in use. There were a couple kernels on the oneplus one (including stock) with bugs like that, but it's not a kernel issue with the axon because otherwise others would have seen this. I'm betting it's a bad app.
I had just installed Kayak. Battery back up now. I'll see if I can reproduce the issue.
I cannot see the usage of apps. Any solution? I also can't see it in the system battery settings.
My buddy has this phone and literally flawless. i mean it works. it lasts. its powerful. has amazing SQ. and im over here with a friggin note 7 barely squeezing 16 hours out of it with3-4 hours DOT/SOT.
Not to mention XDA and everyone gets it wrong. its a 3250mah battery not a 3140mah

I use spotify or pandora via BT. we drove the same distance. same time etc. i lost 17% he lost 5%. both were fresh rebooted and waited 10 minutes. closed all apps and screen NOT in use. no wifi no nfc no nothing.
Can't wait for the battery life to further improve with android 7.1 and maybe even eventually a custom kernel
I'm getting minimum 6hrs of screen on time and i'm very satosfied with this performance

Huge battery problems

Hello, i have a redmi 3 since 2 years, and I've been experiencing some huge drain in battery, when I pull the charger after reaching 100% almost inmediately drops to 94%x I was using resurrection remix, I'm now in Xiaomi.eu MIUI 9.5 and battery life is slight better (I must mention that I use Greenify and bootManager modules)
I'm afraid it could be a hardware problem, this phone belonged to my brother and it had passed a lot of dropping, shocks and liquid, I even bought a replacement battery, problem stays the same, the phone never overheats or hangs so it can't be an internal short.
I've been reading a lot of people talking about 3 days battery life and I always need to charge it after a 11 hour journey
For example this morning unplugged from the charge and did a 30 min videocall via Whatsapp and dropped to 78%. Is that normal. WTH IS WRONG? This is making me NUTS!!!
Hi, I think - your brother is not guilty, because i have same problem with Redmi 3 too long time. After one year and half from day to day -ups- and battery life is in deep ****. I try every ROM - MIUI 7/8/9, lineage ROMs. MoKee, everything, but old stamina battery life did not return. Now battery is empty after few hours and I don´t think she is so ruined ... I have suspect producer from some planned battery life error after some times, because than you must buy new model.... Either way, I did not find solution
Now I have Redmi 5A, but ii is very cheap phone, not so good like ido in any case...

From 12 hours SOT to 2, what happened?

12 hours of SOT is now a memory of a far away past.
I used to score 4-6 hours of SOT in heavy usage, and even 8-12 watching movies, messaging and web browsing.
But now I can barely reach the 4 hours mark, it usually stays between 2 hours (just gaming) and 4:30 (Netflix, web...)
Sometimes I don't really mind getting just a few hours of SOT, but it is really sad looking at the past and remembering that plenty of juice I could squeeze out of this device.
Did also your device got this battery capacity decay? If yes, did a battery replacement actually did something (are the batteries available on sites like AliExpress good enough)?.
Is it really a battery problem or is it a crappy Oreo battery management thing?
PS: I've been using this device for about 1 year and a half.

Visiting the Mi Service centre will be more easy and comfortable....they can give you original battery with replacement warranty of 6 months so....that will be more genuine
It I problem of Battery as it's been used for around 1.5 Year....only those who have newly bought Kenzo like around 6-7 months can say what Oreo battery management is like....it's good or bad....you can try switching ROMs....you will see that you get a extra 30-40 mins of battery n nothing more....which means it's the decay of battery but on the ROM problem...in
I've been experimenting on Oreo and while Doze mode works really well (1% loss by night) I feel that overall battery management is awful, especially when browsing YouTube for instance where I also get 4h SOT max.
I also got my RN3 about 2y ago and battery decay is important due to my heavy usage, with Accu battery I can say that I have no lost about 1/4 battery (3200mah MAX...) But that alone can't explain the SOT loss.
Too bad there isn't any service center in my country I could use a new battery at least for the 1h more that it could give me.

I also checked my estimated battery capacity, and it says 3100mAh (I don't think this is very accurate).
Xiaomi doesn't officially sell phones in my country anymore (they've only sold the Redmi 2).

It's definitely not the most accurate way to check, but based on several charges (more than 20%) I've never seen 4000mah
It's looks like battery degradation. The only way to really check it's swapping batteries. Did you use the stock charger?

Android 10 battery drain OTA Update and HARD RESET

Hi everyone!
A couple of weeks ago I received the security patch and Android 10 for my POCO. It is not yet rooted and running the stock MIUI.
After the update however, the battery life degraded nearly 50% from 5-6 hours of SOT now i have at most 3 to 4.
The Standby battery drain is worse though! Before i charged my phone once in two days (I am not a power user) now i need to charge it everyday! I have more than 20% battery drain at night alone!
The first thing I did after I got that problem was to check if all the apps are restricted, if the GPS is off and so on. I Downloaded the Greenify app just in case but nothing helped!
After that i did a full HARD RESET. After it the Situation got a bit better but still I have no more than 4 hours of SOT and still lose more than 15% at night. All the apps got restricted use and GPS is turned off! The only battery drain function I have active is the WiFi but I got it always on before too!
I couldn't find any solution that would work for me. I was so Inlove with my Poco F1 before and now after the Android 10 update i am starting to feel i need to go on...
Please if you have any suggestions let me know! Thank you a lot!

Question Battery Life after...

I was wondering how the battery life of the note 10 evolves over time.
I've been using the phone as a daily driver over one year now.
And it took the battery almost exactly 1 year until I noticed a sudden degrade of the battery life. I made sure it's not some bad apps. It's rather the voltage dropping earlier now.
I've been using lineageos from the beginning, so I already used a pretty efficient rom that has no bloatwore or the like.
The first half year a full charged battery lasted at least 3 days, sometimes even 4 days (Like: having 75% battery after day 1, 50% at day 2, etc.) And I've been using my phone pretty much all day long.
last month (about the 1 year used mark) I noticed a degrade in battery life. I didn't change my ROM at that time. I was using the same ROM and apps on which the battery lasted 3-4 days before.
Then in just about a few days, the battery began to last 2 days at best. Now it's like having 50-60% battery after Day 1 and I'm going to charge the battery at least every 2nd day or even every day if I'm sure I need much battery the next day...
Now I wonder how this is going to develop over the next months.. will it get much worse? does it stagnate at this level? I'm already thinking of a replacement battery if it becomes much worse soon. But changing battery might be a risk so I'm still waiting.
What's your experience so far? How long and how much have you been using the phone and how has the battery evolved so far?
Can't really say I got the same experience, since I got the phone it would last 2 days and a half with light usage, and 1 day with heavy usage on Android 11 MIUI. And by light usage I mean using it more in the morning and at night, where screen brightness could stay low. Also keep in mind I had the phone for an entire year with this set-up.
But since I changed to LineageOS and Android 12 I noticed the phone barely last 2 days with light usage, it's draining faster while on usage, but in comparison screen off time seemed to greatly increase.
My issues with the battery life on the device seems to stem from the OLED Screen being more I guess susceptible from small amounts of sunlight? On my old LCD phone I could use the same brightness level for every indoor situation, while with the Redmi Note 10 I need to constantly readjust it throughout the day based on the room i'm in.
