You must have a rogue app draining the battery, 6% per hour when not doing much is not normal.

My note 8 had pretty good battery life but yesterday suddenly it started draining extra out of the blue, the android system came up with a warning against a particular app and even after adding the app to "always sleeping" list, it made no difference. Having uninstalled it altogether, battery life is back to being good.

How do you get those long SOT hours? Im frustrated sitting at 2 ish hours. Please see setttings and attached screensho for more info

Setrings

What's the best way to find out what apps are draining my battery?

Other than the stock battery screen on the phone or an app that needs either Root access or a PC (only use Mac at home).
[Samsung Galaxy Note 9 Guides, News, & Discussion] billu:
I don't have root or any special apps.

Normally just rely on the battery section of the phone.

Problem is some apps don't show up in there yet nevertheless drain the battery.

The android system warned me regarding the one yesterday which was a great help otherwise I world be left scratching my head as to what it could be.

Look in battery usage, click on the triple dots in the top right corner, advance settings, notification settings and make sure you have the "battery draining apps" notification enabled.

[Samsung Galaxy Note 9 Guides, News, & Discussion] Janosfodor:
Depends on usage a lot

It depends on where and how I use the phone.

So far, when I was inside in the house and used the phone on a relatively low screen brightness, i got 3 hours of sot at 50% of battery remained.

Today, i was in the city, and because of vacation I was taking a lot of pictures, being out also comes with all day 4g use. Under these conditions i only got about 2 hours sot with 50% battery remmained and i was worried about it, thats why i googled it.

But maybe thats normal, right?

50/50 wifi and Ltd. GPS and Bluetooth on all the time. A little gaming, 20 minute or maybe 15. Impressed. Games are so smooth even with game launcher set to battery saving. Ridiculously good. Will it last though?

I just got my best battery life out my note 9. The following things reduced the standby drain significantly.

1. Under wifi -> advanced -> enable wifi power saving mode

2. Under mobile data -> enable disable data when wifi is on

3. under location -> improve accuracy -> disable wifi and bluetooth scanning even when they are off

4. Add samsung members & gear apps in the always sleeping list.

Doing the above has got me 5:50 mins of on screen time and after 1d and 2h of usage i have 15% battery remaining.

For me since yesterday bought my note 9 n9600ss snapdragon have feeling the battery it's not great like some say, for example all the night without data and lte but always on display on from 100% I go sleep like 2 am and wake up around 8 am look the phone and have 96% or 94%

Check on battery usage but only have AOD some 14% and reception like 2%

I will check if 1 or 2 weeks get better
[Samsung Galaxy Note 9 Guides, News, & Discussion] Dpk1:
I know about the app.. just didn't want to use a third party app to disable Bixby button as it wasn't required on my previous phone (Note 8), I could simply disable it through Bixby home settings. But with note 9, I guess I don't have other option (non rooted phone) than to use an app. Thanks anyway!

my battery life SUCKS! first few days it was awesome, then it just hit the ****ter and got worse then the battery life on my old note 8.

I think the Android-systems is the sinner, it uses almost as much battery as the screen.

it uses easily 15-20% in standby overnight with only WiFi and BT on (no Aod)

any idea how to fix it?

[Samsung Galaxy Note 9 Guides, News, & Discussion] AndyCr15:
Sometimes just a reboot can fix it, but I assume you've tried that. I also think things using Android services (like location) will actually show up as Android System using battery, when it's actual an app making the calls. Did you install anything new?

If all else fails, a factory reset did my battery life the world of good.
[Samsung Galaxy Note 9 Guides, News, & Discussion] ALUCARD4DEAD:
I know that but for example in my s9 the smaller wasted the same percentage but battery size it's much bigger

I would test it without AOD to check results and share screenshot
[Samsung Galaxy Note 9 Guides, News, & Discussion] Majed aka Soul Guy:
Well I resorted to doing a Factory Reset and this time I set the phone up from scratch and just restored my Nova Launcher backup.

That allowed me to see and download only the apps that I usually use and not restore any old files from my Samsung Cloud Backups.

So far I'm happy as with 4 hours of SOT, I'm still left with 40% battery left (which is way more than before the reset), this is considering the million notifications I get on Saturdays from all the live football [emoji460]

Really can't complain now.

I am going to repost this from another forum, can't be @$$'d to retype it lol....

Ok so I have tested the Exynos battery this weekend by doing my normal day to day usage, of course there will be more intensive days but this is my basic usage which would be a bit of Facebook, YouTube, mostly browsing the internet, around 30 mins of calls, texts etc but no intensive stuff.

Now for around one day I used the mid power saving that's because the first day I was using a mix of max power and optimized usage.

I would have let it run further but I need my phone for later.

So,

Here it is........

Now I did do a test on my Note 8 battery in the early days last year also which can be found on this thread....https://forums.androidcentral.com/sa...ml#post6186172

But this was tested using the mid power setting all of the time.
[Samsung Galaxy Note 9 Guides, News, & Discussion] Zanr Zij:
You need to use N9 in about more than week with very standard usage style to get more accuracy result.

Note 2 points:

- Note 9 is just release so maybe AccuBattery need more update to work better

- Samsung component standard still lower than Apple. For example: X Oled screen cost nearly twice Note9 screen

My N8 batt capacity decreased faster than my IP7+ batt. Both charged by Anker charger same way!
[Samsung Galaxy Note 9 Guides, News, & Discussion] jstodda:
I've already posted SOT and all so I'll give a few cents on things that have helped me. (I got 9 hours SOT my first battery run).

You CAN just disable everything and turn your phone essentially into a black and white candy bar non smartphone with 4 days of battery life (go buy a nokia then) OR just disable non essential apps FOR YOU. Everyone is different.

Here is what I did.

1. Download "Package disabler pro + from app store"

2. Use it to freeze apps you dont use. Dont worry about how crazy you can go. Here is how to start

3. Pull your battery / memory apps from the settings menu

4. Notate anything running that you won't use

5. Swap back to the app and simply search and disable it.

Go as crazy or as conservative as you like. You can unfreeze easily. Here is what I did:

1. Anything involving Bixby

2. Tmobile bloat (VVM, ACCOUNT APP, ETC)

3. Many Samsung apps, especially Samsung cloud)

4. Many of the edge apps

Additional options (many have been stated before)

- disable data during wifi use

- enable wifi power saving mode

- use auto brightness and tune often as low as you're comfortable (it will learn as you go)

- add as many apps as you can to the "sleep when not in use" list

- open each app you dont use and disable "usebackground data" option

For additional savings try "naked browser" and other "lighter" versions of apps.

Good luck!!

Don't restore from previous backup if you want best battery performance. Install your apps some at a time and see how they affect performance because 1 or more apps can be a rogue app on your Note 9.

Sam factory is about 40km from my home. I have trusted sourse to make sure this: X screen need 30 steps to make while Note8, 9 screen just need 15 steps only. That's why X screen cost much more higher. X panel percentage to pass test also lower than Note screen. That's the main reason X screen cost much higher than Note'.

Just a word of caution, VPN apps seem to be sneaky little battery hogs as well. Had to uninstall and then reinstall the one I use and that fixed it. It also didn't show up in battery management as something using alot of battery. Also, it took almost 2 weeks for battery to settle in. I average 5 to 6 SOT with an 80% charge. So I am having great battery life for me.

The Iphone X screen is no where near as good as the note 9 screen... it cost twice as much because Apple had to buy it from Samsung.....

Tested both my exynos and snapdragon note 9's side by side with same apps. At the same time. Gf looking at me like I was so weird. Xxx

Benchmarks

4k 30 minutes movies

Games

The tests drained about 40% battery from the phones it seemed as I get rid of the percentage amount of remaining battery in the options. So upon checking I saw....

Exynos 53% left

Snapdragon 61% left

7 to 8 percent difference

The exact same applications, exact same phone state, phones both in flight mode, everything off like Bluetooth etc and only WiFi on connected to same network. Screen at same brightness, a carbon copy of each other, same apps installed etc. During the test accubattery consistently showed less drain with its live current battery drain overlay option in video watching, cpu tasks and especially gpu heavy moments.

CPU spy showed the Exynos using the higher cpu clocks much more than the snapdragon. Snapdragon hovered at its lowest cpu state a lot longer. Surprised how much snapdragon is smoother in everything and used a lot less battery. We knew it was better but I didn't think by this much.

If tests were to continue till one of the phones died, I'm guessing roughly the snapdragon would have around 16% left while exynos would be dead. Not the most scientific test but it gives a good idea. I have pics of some of the results, if I can be bothered to put them up, I will.

The Exynos was returned.

[Samsung Galaxy Note 9 Guides, News, & Discussion] KOLIOSIS:
Go to each apps settings (SETTINGS > APPS) & turn off background data for each app that it's totally unnecessary.

That should get you some improvement.

The next area I'd look is the quality of your Cellular/WI-FI Connections. If either are weak,that's gonna be a significant drain.

Check your developer optoins settings regarding Cellular/WI-FI & make adjustments if you deem it necessary.

On Wifi use (90%) with 4G data (10%), battery backup seems better than ever! 4+ hours of screen on time with half a day standby and 62% battery still left! Going at this rate I would easily get 10.5 hours of screen on time and about 1+ days standby. All stock here with default white theme and only a few apps disabled (through settings). Best battery backup I've ever had on any smartphone!

Does anybody know what version of envelope tracking Qualcomm is on or is it called RF360 now? I wonder if Samsung's modem is not as efficient as Qualcomm's. I've been getting better battery using LTE than WiFi since my note4. My wifi routers have not been a slouch either. My snap note9 just trickles off the battery watching YouTube videos. I wonder how much better Qualcomm's ISP and DSP are compared to Exynos. Anybody able to track these details? I've been getting over 10h SOT easy. My battery has not dipped into single digits yet either. I've almost hit 11h twice and my battery was in low twenties or high teens still. Everybody keeps blaming Samsung's CPU but I wonder if it's other factors. I would think Exynos gets higher binned screens and Made in Korea. Just a thought.

Exynos 128G SM-N960N

I couldn't be happier with battery life on the Note 9. For me, it's excellent. I just added a handful of apps to the "always sleep" list.
[Samsung Galaxy Note 9 Guides, News, & Discussion] high_voltage:
If it was about to come, it was going to be for the note 9 release. The problem is combination of software/control of the SOC and hardware. Samsung clearly doesn't have the qualcomm team to do the control part and they can't change the hardware limitations (great reads on that on the web, like @ anandtech + even some kernel tweaks for better behaviour, sadly still far behind the snapdragon845).

Won't repeat in depth what everyone here said or go technical, you did a real life observation that sums it up perfectly (10x for that, btw). I guess next year we will see the M4 core and SOC that is what this years 9810 should had been, but then again, we will also got the next snapdragon and if the trend continue - it will dominate in real world performance and blow away in GPU.

My honest advice to anyone is to avoid 9810 powered device, it's not worth the high price tag. Still a ok SOC, but so so much behind the sd845 that it's not even funny.
[Samsung Galaxy Note 9 Guides, News, & Discussion] Venom0642:
Thats correct Exynos has battery issues, everyone i know has these problems, Snapdragon is way ahead and it's Outstanding which is the one i have AT&T Note9 get about 9hrs 45 min to 10hrs and 17min SOT with over a day not being charged.

Are y'all sure it's the CPU? It could be auxiliary chips like ISP and DSP not as well optimized. Samsung should also consider moving away from Mali GPUs and go with imagination technologies. It was the supplier Apple used for quite awhile before going in house. Wouldn't be surprised if Apple has taken some IP and implemented it on their own. Hard to tell since studying at nm scale is hard and cases like that I'm court are hard to judge. Only a handful of phones have used imagination technologies GPUs. I think Galaxy Nexus was one of them and that phone performed well and had great battery life for a 2000mah battery and the screen was much larger than iPhone at the time. Besides, IT could use the business losing apple as a customer. Quite sure they would be happy to get some new customers. Mali GPUs have been weaksauce anyways for quite awhile.

[Samsung Galaxy Note 9 Guides, News, & Discussion] high_voltage:
It goes beyond that, the sd is provenly - more efficient leading to a vastly better battery life, faster in real world scenarios, smoother and with far less frame drops and on top of that it has around 35-40% faster GPU in games.

If one go and buy xiomi poco f1 for 300 euro, he will have a lot better time playing games(and battery life, and app performance, and UI smoothness) vs one with 1000-1250 euro note 9 in Europe. It's one thing to have the same leading SOC as the rest and a lot of other features for that price, but it's not to have a SOC that is between the mid range and high end.

In my honest opinion, samsung should had drop the exynos 9810 atleast in the note this year and buy sd845 for all the variants. Ofc they saved money for our price.

The note 9 is the best android phone for sure, but only in it's sd845 variant.
[Samsung Galaxy Note 9 Guides, News, & Discussion] high_voltage:
It's not only the CPU, it's everything around it that is better in the qualcomm sd845 SOC + the control of all that is better. As for the GPU, the bitfrost architecture failed big time. Samsung already started their inhouse GPU, but imho it's too late and should had started a lot earlier.

Historically, I've never had good battery life on any phone and I've also had to factory reset the Note 9 and only install the apps that I needed and I managed to bump up my SOT from 2 hours to just over 4 HOURS SOT.

That's still no where near what most people are posting and I'm yet to confirm if it's solely down to the Chipset (mine is the Exynos version).

Ps. 4 hours of SOT is more than I ever used to get with any other Android which is why I'm accepting it.
