I am currently on 54% battery, with SOT of 4hrs 39m, came off charger 10 hours ago. I have used the phone on 100% brightness for 1.5 hours and 50% for the rest.

Various accounts syncing. Instagram, Internet. Texts.

The battery life is incredible on here.
[Samsung Galaxy Note 9 Guides, News, & Discussion] Zanr Zij:
These are realistic results :)
[Samsung Galaxy Note 9 Guides, News, & Discussion] michelino159:
Those SOTs had Notes8. Now Note9 must be the same? Where is the battery upgrade? Do I understand that only those who play for hours do make the SOT realistic? Those who are not playing and jumping for 8h SOT have the save mode enabled? You are funny ! Point.

What are you talking about?
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
You seem to judge that only by looking at SoT but these results are not even close.

In one hand, Karan is getting almost 6h of SoT at 4% battery left but he plays more than an hour of PUBG.

This game consume in an hour what YouTube consume in 3h.

His battery life is quite good IMO.

In the other hand, themaximillian is getting around 4.5h of SoT at 31% battery left but more than half of his SoT is on YouTube (which really isn't that power hungry).

He seems to play but to clash of clans which is also not power hungry.

Add to this that his battery life deplete is linear after what I assume was sleeping time and you will understand that something was draining his battery. I will guess that it has really poor signal where he was today and that's what killing his battery.

His battery life is not good at all IMO.
[Samsung Galaxy Note 9 Guides, News, & Discussion] michelino159:
I was talking to my colleague [MENTION=3241487]Zanr Zij[/MENTION], who said that the 4.5hrs SOT are real for exynos, and those who have more have the function of saving energy.

I don't know how some of you guys are getting such great battery life. I find battery life to be average at best. For example. When I went for a run with the p20 pro let's say 40 minutes. I have the gear s3 and jabra earbuds connected. I would lose about 2% with the p20 pro compared to 12% with the note 9. Haven't really made it through a whole day yet. I lose about 14% overnight in like 7 hours. The Huawei P20 pro would lose about 2 percent. It's just a regular old galaxy battery life for me. Nothing to write home about. I find myself topping up quite often. Thank god for wireless charging...
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
That's the things bugging me since the beginning. As I have already told, my Note 9 have a better battery life than the one of my wife.

I know that usage patterns, signal, apps installed, ... can have a huge impact on battery life. But since we live in the same place and we are roughly using the same apps, I would except similar battery life but it's not the case.

Even if we both play the same game for the same amount of time we will end up with the game hitting battery more on her phone than on mine (And you can even see it in battery stats. The game will take an higher % on her phone than on mine).
[Samsung Galaxy Note 9 Guides, News, & Discussion] bonerp:
I go to bed after a full day off charge and regular use (web, email, text, music, BT headphones, galaxy watch, FB etc) and easily have 50% remaining on my exynos.

I think its excellent. I'm not a light user by any means.

My note 8 was dying by 8pm and struggled to make it through often requiring a top up.

The only thing I've done to it is add a handful of apps to the always sleep list. The list is at the bottom of the device maintenance page. Apps I found running in the background that I don't want using battery because they aren't important went on that list.

The only other thing to note is that I have 4-5 bars of signal where my phone is most hours. This last round of battery use was with 100% cellular use. I did't use Wifi just to see what the impact might be.

Overnight Battery drain - Please Help

Hi guys

I'm using Exynos 6GB variant (Indian Version).

I have posted the screenshots of my battery usage overnight. I believe the drain is higher than usual.

Only Wifi, GPS and Sync are ON. Could anyone help me find out the issue?
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
I'm not familiar with BBS and GSMB but it's pretty clear that something is wrong in your screenshots.

App usage is way too high considering that you don't seem to do anything power hungry and something is keeping your phone awake while screen is off.

It might be a problem with data sync seeing at GSMB but I'm not sure since I don't know how GSMB works.

My final results on my battery life AT&T Note9 512GB Snapdragon, on September Security patch .
[Samsung Galaxy Note 9 Guides, News, & Discussion] karan2012:
Sync is one of the feature that takes a toll on your battery also if you are using sync only for email I recommend you using Bluemail and set sync to push with 1 hour interval , also GPS checks if location history is on or off and try using GPS in battery saving mode unless the phone demands high efficiency mode, also in wifi settings turn on wifi power saving and one of the biggest thing that helped me was battery calibration discharge your device till 0 and let it die completely then charge it to 100 at a single stretch reboot and start using it , perform this 3 to 4 times and you will see improvements.
[Samsung Galaxy Note 9 Guides, News, & Discussion] Venom0642:
Here's my battery life today AT&T Note 9 512GB, as you can see the day before i got 10hrs SOT which i posted on top and today's SOT is over 9hrs, so everyday, it's different for me depending how i use the phone, but i still manage to get over 9hrs to close 11hrs, since day one when received my phone.
[Samsung Galaxy Note 9 Guides, News, & Discussion] Spacemaine9596:
Hi, I've got a few questions. How do you charge your phone? What apps do you normally use on a single charge? What apps do you have installed? My battery stats consistently show "android system" as #2, below the screen of course. I've done everything from factor resetting it, clearing the cache, installing a dark theme, removing installed apps and reinstalling them 1 by 1 to see if it was a rogue app. But nothing seems to change the android system from being #2. Usually the percentage is half the SOT but sometimes it'll be closer than that. I see other people's and it'll be below 10% or well below 50% of their SOT percentage. I get through the day no problem but nothing like others on here.

31h charge. Still haven't run battery down to single digits yet. YouTube or videos was not my highest battery drainer but Chrome. This charge was varied in many facets with challenging reception and T-Mobile being slow yesterday (Friday) afternoon.
[Samsung Galaxy Note 9 Guides, News, & Discussion] hkjxda:
Happy for you man... It's a little depressing looking at all the stats in here, because on my snapdragon note 9, I'm only getting 4-5 hrs. SOT max. Not sure what I'm doing wrong. I've tried every battery saving tip in the book.
[Samsung Galaxy Note 9 Guides, News, & Discussion] @rbiter:
There are many many variables involved. The theme you use is probably the biggest factor you can come troll. Network used and how. Like I am on T-Mobile and I have disabled 2g. Unnecessary for my phone to even be bothering with that. I have also trained my brightness to be less aggressive. Many people like using their phone on high brightness and think they're supposed to get great numbers like I am. You should check out Marques Brownlee's SOT. He uses full blast brightness all the time and his expectations are realistic. And I don't use social media. Many people do. The more you need to be on the forefront of what social media the more your battery drains. My expectations for battery life were not as optimistic as my results. To each his own. Just because you're not getting double digits SOT like others means you're phone is draining battery somewhere else. All my sync is on, Bluetooth is always on and heavily used, GPS is left on. I think next charge I turn off BT and GPS for hahas and see if there is noticeable difference.
[Samsung Galaxy Note 9 Guides, News, & Discussion] bober10113:

[Samsung Galaxy Note 9 Guides, News, & Discussion] mehtamitul:

If you do the math, that would be over 8hrs of playback on a single charge, not including anything else.

Even 1/2 of that, with all other things considered, doesn't sound like a problem to me....
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
I still search for someone with an Exynos Note 9 and a not so good battery life to take some basic measurements on power consumption.

Back in the Snapdragon 805 days, for example, Qualcomm was using 15 different voltage tables because some s800 weren't as good as the others. As a result, the bad ones were using a voltage up to 23% higher than the good ones.

Might be something similar here.
[Samsung Galaxy Note 9 Guides, News, & Discussion] themaximillian:
What's considered "not so good"?

Asking because it is often relative to expectations one has.

[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
The worse, the better. If there is some differences, they will be easier to spot this way.

It's hard to put a real number, there is too much factor IMO.

Edit : for example, someone having 5h SoT over 12h off the charger with brightness at 10%, everything off and no heavy apps, has a really bad battery life.

But someone having the same SoT with 3h of PUBG, everything on and brightness at 80%, has a great battery life.

I just got my Note 9, from T-Mobile, a couple of days ago. Just got off of my LG V20 after almost two years. Slowly "putting accounts and apps" onto the Note 9 now. I have a lot of Google/gmail accounts due to my kids I have to monitor, along with work, and other accounts. I have come to an understanding that I am a heavy battery user. After my experience with the LG V20, and the additional Zerolemon battery that I had to buy for it after the first year, I know that the battery in the Note 9 will degrade just as fast. Too bad manufacturers don't want to produce a device with a replaceable battery. I am enjoying this Note 9 and coming back to Samsung as I had a Note 4 previously. RIP Note 9 battery when the time comes. Hello replacement device, when it comes out to upgrade...

[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
Not sure to understand your question.

If you're asking about the measurements, just send me an mp and we will start.

I think it will take around an hour of your time and during this time, you won't be able to use your phone normally.

If you're asking what to do about your SoC, sadly there is nothing to do. You have to wait for a custom kernel that let you undervolt. But even then, if there is a too big difference in voltage, you might not be able to reach the same voltage as the best SoC.
[Samsung Galaxy Note 9 Guides, News, & Discussion] a2kay:
Exynos. Here are mine stats. First two pictures from Friday and the last from yesterday. The stats are good ?
[Samsung Galaxy Note 9 Guides, News, & Discussion] LiquidSnake9:
I just charged the phone so not possible right now. I'm just curious how you get almost 12 hrs of SOT with almost similar usage like mine. I've disabled 80% of the Samsung apps, don't have alot of third party apps but all of them have been put to sleep permanently and screen is set to FHD+.
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
After reading the sources from a S9's Kernel, I'm sure that Samsung is still using different voltage tables because I have found references to ASV which is the name of "binning" for Exynos.

But from what I understand, they are not only binning the SoC as a whole but are binning the CPU Cluster0, the CPU Cluster1 and the GPU.

As I have already said, I don't do anything special. The only thing is that, the day I tried to deplete my battery and get almost 12h SoT, I was mostly indoors so even with brightness on auto, my brightness was certainly low.

But even if I take a screenshot right now, I still get far better battery life than most people here (5.75h of SoT after 18h off the charger and 47% battery left).

A few days ago, I installed Accubattery to see how much the SoC was consuming on various activities and I still haven't removed it so you can see my average battery life over a week.
[Samsung Galaxy Note 9 Guides, News, & Discussion] LiquidSnake9:
I don't really understand what you're talking about dude, it seems there is a misunderstanding. I'm just trying to ask you how you get 12 hrs of sot while I get around 7-8 with similar usage as yours

[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
This post was not for you. It was just my findings regarding differences between different Exynos 9810.

Again, I don't do anything special, I use my phone stock, I haven't disable anything until now, I just don't use bluetooth and don't let GPS on when I don't use it.

Brightness is on auto, no dark theme, all sync on, I use phone over WiFi at home. No power saving mode (it make my phone laggy).

That's why I'm guessing that like the old s805, some Exynos 9810 use way higher voltages than others. (And it effectively seems to be the case)

Here is mine. BT on and used, GPS on, power saver is on but only CPU limiter is used and WQHD+, Today was light usage as I am still setting my phone up.

[Samsung Galaxy Note 9 Guides, News, & Discussion] yourmumsbootloader:
1% every few minutes is terrible. I average about . 7% an hour. Need to find whatever is rogue on your phone.
[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
It could be a lot of things. Brightness that ramp up, modem searching for connection in a low signal area, a sync stuck in background, a poorly optimised app or service, ...

First, you will have to check if nothing in particular consume power more than what's expected.
[Samsung Galaxy Note 9 Guides, News, & Discussion] LiquidSnake9:
I confirm to you that brightness was the same, sync turned off. I did tried installing a few browsers to test which one is efficient but all of the ones I installed had the same irregular battery drain. Wifi signal strength is full but sim card network constantly switches between 2-3 bars

[Samsung Galaxy Note 9 Guides, News, & Discussion] alex989898:
Might be in someway link to how many times you load a page or touch the screen (both ramp up the CPU frequency automatically).

I doubt it will make such a big difference but it might explain part of the behaviour of your phone.

Why don't you try installing Accubattery and take a look at the range of mA your phone consume when you just stare at a page without touching it and when you scroll ?
