Sorry, clarify me one thing, 7.30h screen on time, is from the screenshots you posted.?

And what was the charge in the middle for?

Sorry but that doesn't count.

Put some screenshots 100 to 0 to see your usage.

And by the way, I turned off the iris scanner for 2 days and doesn't notice any difference in the battery. Regards
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Yes, please look at the first screenshot, it says "100%." It would been the same as if I drained the battery from 100 to 0% ;) I try to keep the battery % between 40 and 80%..

Do you have the snapdragon version? I think the face/iris unllock bug is only on exynos :)
[Samsung Galaxy Note 9 Real Life Review] cavags5:
I have exynos version, and didn't notice any difference..
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Did you restart your phone after turning off iris unlock?
[Samsung Galaxy Note 9 Real Life Review] cavags5:
Yes of course, i use to test a lot of things, but now I'm I little off.
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Hmm, maybe you are just lucky then and don't have the bug :laugh:
[Samsung Galaxy Note 9 Real Life Review] cavags5:
Usually this days we have less bugs than before, things are well optimised, and sometimes some drains are from users not software.
[Samsung Galaxy Note 9 Real Life Review] dawidk750i:
I have snapdragon version. No difference.

I did a factory reset and watch a lot of youtube at low brightness ?
[Samsung Galaxy Note 9 Real Life Review] pistutm:
Hey Guys.

I hope someone can help me with my problem. My exynos note 9 is about 4 months old. Bought it new and unlocked.

Since the beggining I am having pretty the same battery life as on the screenshot below. Most of the time charging from ~20 to 80%, occasionally fast charging (max once a week). Facebook services and most of the bloat apps are switched off. Usually no gaming, just tried the cod mobile.

No wifi at all, 0-24 volte 4g, 6-8 hours of bt for wear os, aod on tap only, no intelligent unlock, only fingerprint and iris (if swipe on lock). Wifi + bt scan is also off.

Btw this was a very (unusual and) light day. During weekdays i have to charge the phone in the afternoon if i want to make it home after work.

What should I do to increase the sot time?

Tried factory reset already.
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Try turning 4g off when not using it.. it sucks a lot of power ;)
[Samsung Galaxy Note 9 Real Life Review] pistutm:
Thank for your reply.

I will try it, but due to my job i must be online a lot.

During night i switched to airplane mode before just to see how much juice i can save, but it was not too significant.

Is there anything else i can/should check or try?

I am just curious, but without online connection i barely could use the phone as a smartphone. So you all switching connections off every time to reach 5-8 hours of sot?

Thanks in advance.
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Are you on the latest update?

Try download gsam/betterbatterystats to see what is draining your battery (you have to use adb tools on a pc to give it permission)

Install Naptime to force doze when screen is off (also adb)

Always Optimize batteryusage on all apps. (In settings)

Reboot your phone almost every day. (Also try wiping cache partition)

If it does not get any better, I suggest sending it in for a warranty fix.

No, I have wifi on all day, and 4g at work.

I got tired off bad batterylife on my note, so I bought the Asus ROG phone 2 instead. It has amazing batterylife! 2x+ better than the note 9! And with the screen running at 120hz. :D
[Samsung Galaxy Note 9 Real Life Review] pistutm:
Yes I have the latest update insfalled.

Are those adb stuff (naptime and batterystst) warrantyfriendly?

I usually reboot the phone 1-2 times per week, will do it every day then.

Will check this tis optimizer, but i think its on since day1.

I guess 120hz is way better, but as long as i dont get used to it will not miss it. Hope at least. :D
[Samsung Galaxy Note 9 Real Life Review] Jovan1997:
With every new update battery go better and better
[Samsung Galaxy Note 9 Real Life Review] pistutm:
Nice!!

If i could reach 6 hours of sot, would be happier than ever....
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Yeah, adb won't void warranty :o

---------- Post added at 10:22 AM ---------- Previous post was at 10:19 AM ----------

Did you factory reset the phone recently? after the latest update?
[Samsung Galaxy Note 9 Real Life Review] dbappa:
Hello, been ages since I was last on here (does Dr Ketan still do amazing ROMs?).

Any way I could easily get 5-8 hours SoT with my Exynos Note 8 though it didn't always last until the end of the day. Yet I get 3-4 hours with my Note 9 (Exynos). My usage hasn't really changed but I am struggling to see why my SoT has essentially halved especially with a bigger battery. I ran Greenify and Package Disabler Pro for months followed by months without either - the difference is barely noticeable. I run the phone at 1080+, optimise apps and restart a few times a week. It sounds like there more steps to do reading the last couple of pages but an average of 3-3.5 hours of SoT is frankly ridiculous and my Note 8 would be laughing at this.

This is meant to be a no compromise phone and I don't mind making one or two (e.g. 1080+ as that's still sharp and I can only tell the difference side by side) but something doesn't seem right. Other than that I still love it, time to do some more reading.
[Samsung Galaxy Note 9 Real Life Review] Bober_is_a_troll:
Lots of things effect sot. One of the bigger less talked about factors is signal strength. If you have poor service, it can be a big drain on battery.
[Samsung Galaxy Note 9 Real Life Review] dbappa:
Thank you for your reply and I forgot to mention signal is an issue/aware it can impact. I live in London and was with 3 for years that did poorly for most of my working week (large parts of where I lived, the main train station I went through to work, parts around my work, buildings, bad weather, trains - so basically most places). I am now with Vodafone who are a bit better but still not great.
[Samsung Galaxy Note 9 Real Life Review] Bober_is_a_troll:
Yeah I worked in an old brick/stone bank. The best I could do was 140 kb/s download over 4g. 3-4 hours sot in there easy.

But when I'm out and about using WiFi and being outside with great coverage, it goes up to 6-7 hours SOT
[Samsung Galaxy Note 9 Real Life Review] cybermac78:
yes i get there as well with monosim (with dual sim aroun 3,5 hrs) i guess you're exinos not snapdragon being you turkish, is this right?

Anyway it depends a lot on too many factors like environment (using the smartphone outdoor with auto-brighntess featur pushes the brighntess to the limit reducing the autonomy), the kind of use (if you are a gamer forget to have those values in screen-on-time :) ) number of installed application (the many you have the many are trying to refresh/update/syncronize evry now-and-then eating the battery out), the processor (exynos is less efficient while snapdragons is more efficent), the area (if signal is low the antenna's attempts to lock the signal is very power consuming) and i guess a lot more actually...

---------- Post added at 05:33 PM ---------- Previous post was at 05:27 PM ----------

the need to optimize sw not augment the battery :) mate 20 pro with about hte same battery (slightly more) does 2 full days with mid/intense use. something that we can only dream of with samsung
[Samsung Galaxy Note 9 Real Life Review] sjjjd:
Not bad at all.

stock, latest pie, airplane mode on ( I don't use mobile network) battery health is at 90.3%
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
Well you would get that kind of screen on time with the Mobile data off. You are running the device on the most efficient way possible. Also you have used YouTube for over 4 hours which will also boost your SOT. Looking at how you used your phone this is sort of expected
[Samsung Galaxy Note 9 Real Life Review] sjjjd:
Yeah, wanted to test it tbh. 8hrs sot is my normal usage, with airplane mode off, 3g network (using wifi ofc)
[Samsung Galaxy Note 9 Real Life Review] bebomonir97:
How you can know your battery healthy????
[Samsung Galaxy Note 9 Real Life Review] sjjjd:
Install phone INFO then go to personal tab
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Wow,280 cycles and health 75,80%.I can not believe. ?
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
That's really weird as [MENTION=8132601]bober10113[/MENTION] has much more cycles with less wear. I don't think he or she even does the 80-40% charge discharge method.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
In the previous version of PhoneInfo I had 95%. I have them both. What does the correct value show? :)
[Samsung Galaxy Note 9 Real Life Review] bober10113:
no it dosent.

it dosent put the lotion on its skin either.

but new update of the app did soemthing.

im at 257 cycles and 80.05 now. i was at around 85 or so %...no?
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Lord knows. I'm using current version on s10plus and it says 99.6% at 62 charge cycles.

Version 3.8.0
[Samsung Galaxy Note 9 Real Life Review] bober10113:
i almost figured out where the values are stored... lol i found head phone, charge plug and spen counts tho.....

[Samsung Galaxy Note 9 Real Life Review] Jovan1997:

[Samsung Galaxy Note 9 Real Life Review] BLEK0TA:

[Samsung Galaxy Note 9 Real Life Review] zeroloss:
great result. are you using stock ROM with stock kernel or modified ?
[Samsung Galaxy Note 9 Real Life Review] darthmalus:
I have gotten 8 hours of screen on time on 8.1 but after the Pie update my battery life has been atrocious. I have a snapdragon model.
[Samsung Galaxy Note 9 Real Life Review] ramiss:
I too have noticed what seems like a battery decline after the upgrade. I'm yet to be convinced though if it is an actual decline or perceived due to the battery stats needing to recalibrate.
[Samsung Galaxy Note 9 Real Life Review] VortexHD:
Hello,

Just wanted to know if this was decent battery life on my Note 9. Have had it for a year and 3months now so battery level is at 87% according to Phone Info.

https://imgur.com/a/fgzhmGx

https://imgur.com/a/cGc4kaZ

I usually charge it in lessons from my laptop which gives about 10% in an hour and a half which gets used super quickly. Hoping One UI 2 has better battery life otherwise I might replace the battery.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Should have done the 80-40 charge method.
[Samsung Galaxy Note 9 Real Life Review] fun4357:
Well, I got 90.20% with 390 battery discharge cycle. Does not seem too bad but the battery now only last me for 5 hours of SOT.
[Samsung Galaxy Note 9 Real Life Review] amit020:
Is there something wrong in my device, my battery count cycle is just 43 and battery health is 94%, and I'm getting around 3-4hr SOT on moderate usage.
[Samsung Galaxy Note 9 Real Life Review] BLEK0TA:
My batt health
[Samsung Galaxy Note 9 Real Life Review] michelino159:
If you update to Pie it will show you around 80% health. I see that the whole thing is software approximation and not a true measurement.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
What can I not understand and please if there is a colleague to enlighten us, the internal measurement, that counter_charge that looks at the 100% -3753mAh load is a true measurement or an approximation and this value? If the system has a measurement of the number of mAh you enter by what bad health looks like.
[Samsung Galaxy Note 9 Real Life Review] zybtron:
mine too. Purchased a new note 9 dual sim. one week ago

battery health is at 94%

battery count is at 7

the phone was manufactured last year - nov 2018

not sure if the old stock is an issue.

standby drain is at 1.2% per hour
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
All this bull$hit could be resolved if google implemented a system wide battery health setting. Second hand users of Android devices would also greatly benefit.
[Samsung Galaxy Note 9 Real Life Review] amit020:
I think it might be a software issue, few days back battery health before charging was 94.10% and after charging it became 94.18% and now it is at 94.45%.

Strangely it's increasing now.??

Just wait for a couple of days and check whether it's decreasing or increasing.
[Samsung Galaxy Note 9 Real Life Review] zybtron:
If so, I am glad.. i have been using S8 a year ago. Battery life gets better after a few weeks.

hope it gets better in note 9

still skeptical about standby drain with dual sim, wifi on - i am losing like 8% - 10% overnight

lets see
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Correct. According to estimates, I should change the warranty. But if the battery is good and a bad change.
[Samsung Galaxy Note 9 Real Life Review] amit020:
Even I and most of the user having same battery drain issue on Exynos Version.
[Samsung Galaxy Note 9 Real Life Review] zybtron:
thanks for letting me know..

Its a fantastic device..
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Today it has updated PhoneInfo. It does not show battery health just cycles. ?
[Samsung Galaxy Note 9 Real Life Review] michelino159:
I found on another forum another battery monitoring application. The values ​​are exact as those found with adb. I don't know how to read files protected by the system like fg_asoc or fg_fullcapnom.

Real Battery Stats for Galaxy S6

https://play.google.com/store/apps/details?id=com.meowsbox.battery_stats_s6
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
The adb commands are exynos specific right? For battery
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Yes,for exynos.In the adb fg_fullcapnow command it has the same application value.

The application reads your fg_fullcapnom file from sys /../ battery.It is the same file that PhoneInfo read but it converts it into percentages and this application shows you mAh read from the file. I do not believe this value. It's an approximation based on time / cycles / temperature. That is, if you have 250 cycles you should not have more than 85%. I do not think. I do not see a substantial reduction in autonomy and charge_counter = 3753 mAh at a full charge of 100%.
[Samsung Galaxy Note 9 Real Life Review] bober10113:
when you factory wipe or flash new firmware, system is reset. the only place i know of on a phone that is never erased is the EFS partition.(parts of it)

values of said file are probably taken from efs partition or something. if one would do a backup of efs partition and restore it 1 year later...id like to see if it resets the health...
[Samsung Galaxy Note 9 Real Life Review] michelino159:
The values ​​are not reset. I have reset the phone, I have recently written a new firmware and the values ​​have remained the same.

The only method of changing the values ​​remains the total battery discharge.Have not tried.
[Samsung Galaxy Note 9 Real Life Review] bober10113:
system

vendor

odm(carrier configs)

are partitions that get completely wiped

efs

dosen't.

so my guess that's where everything is stored.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Are you on Oreo? You can't on Pie anymore, you need root.

---------- Post added at 11:08 AM ---------- Previous post was at 11:04 AM ----------

Battery information is in sys / power_supply / battery. When he was on Oreo, they could be accessed but with Pie they couldn't.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Don't you think something regarding the battery readings changed after Android 8?
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Yes, don't read them properly :D
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
It started from Android 8 didn't it?
[Samsung Galaxy Note 9 Real Life Review] michelino159:
I do not know what to say. In my opinion Samsung batteries do not have Apple electronics on them, they are simple batteries. The software monitoring is strange and not to panic in users with alarmist numbers protects their files to access them only with root. You as Samsung boss announce to Note8 that the new batteries lose 5% in 2 years of use, instead it shows me the battery health made by your 79% software. How's that coming?

---------- Post added at 07:37 PM ---------- Previous post was at 07:31 PM ----------

Shouldn't I have some real values ​​to know what to do? Maybe I want to change the warranty if it's expired. I have an Iphone7 in my house for years. It is charged only at night without having to worry and it has 84% ​​health. And with Nite9, I was careful not to download below 25%, loaded almost two days, not at night I have 79% health? How's that coming?
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
That's why I'm in favor of google building a hardbaked tool within their OS that can correctly measure Android battery health via user interface.
[Samsung Galaxy Note 9 Real Life Review] bober10113:
this is a "working space" and i dont think this is where data is stored. if you wipe/flash full stock, this would be erased and overwritten. so its means the actual values are stored in a non volatile area so that uppon reset, they can be restored. i suspect the true values might be in EFS.

in an example. if i were to flash an aosp rom. it would wipe that sys folder. but im sure if i flash back stock. my battery health values would still be there...

maybe this is something i need to try but even without doing it i have a feeling of what to expect.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
You don't really understand. I reset the phone, I installed another software and the data does not change. When you have root you can delete with twrp what you want. When you do not have root, only the "date" partition is deleted.

---------- Post added at 08:53 PM ---------- Previous post was at 08:51 PM ----------

Only changes made by the user and stored on the date can be deleted. No matter what you say. When you have roots you have another job.

---------- Post added at 08:55 PM ---------- Previous post was at 08:53 PM ----------

This is valid on the exynos, I don't know the snapdragon.
[Samsung Galaxy Note 9 Real Life Review] bober10113:
when you flash stock firmware with odin, system, vendor, csc and other partition arent flashed?

we all know they are.( except EFS) and again in an other example, i manually delete system and the data still comes back. so it kind of proves my point that the actual data is not saved where you say it is. its a working folder where the system processes and shares it with other resources.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
I think he's talking about flashing it the regular consumer way.
[Samsung Galaxy Note 9 Real Life Review] bober10113:
regardless om going to install linegae OS and then install a stock rom. no restores and then check back in the phone info app to see if results have changed or not.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:

Flashed from

Flashed gapps

Flashed boot

3= 16h36

Wiped system,data,caches

Installed super stable rom with wipe option ( basically same as above but just to be sure 2x the wipes)

Btw what ever is in root/sys is kernel territory if I'm not mistaken. And in each case a fresh boot.img was flashed(kernel)...

I use GSAM. It's better for these type of figures. You can set it's measurement stats from last charge, last unplugged, last screen off and my favourite for measuring overnight loss "since now" . Try it.
