S8 Oreo Battery: Documented and straight-forward results? - Samsung Galaxy S8 Questions and Answers

Tired of the BS "mixed reviews" that shouldn't happen on the same hardwares (S8) with the same version (S8).
So instead of wasting time not finding a real answer I want to ask this in a straight-forward way:
1. Are there consistent documented tests and reviews about battery life on Oreo vs Nouga ?
2. Or, are there clear and precise explanation of what influences these battery life variations (stock vs. xrom, factory reset vs cache clear, settings etc...) ?
Thanks.

[ Q ] Desire HD ROM for HD2 with *best* Battery Life ?

Hi
Wondering if there is a general consensus as to which Desire HD ROM build has the best Battery Life ?
Thx,
Ben
i use this build:

As far as I am concerned, I removed this rom because I had excessive battery drain with it (empty battery during the night without any use) and changed to this rom :

and I am particularly pleased with this one

Strange, i have max 5% overnight. Really can't understand how the same phone with the same build has so different results. Maybe radio version or sd card?
@OP
As the above 3 posts prove, there is no *best*. You have try a few for yourself and find out which works best for you. Besides, it's good practice at flashing new ROMs and gives you more exposure to what's available.
Good luck

Some words should never be used here (and in real life)
best : depends on conditions, on what to expect, etc etc
fast : as equal as 'best' but even worse, the need for comparison.
normally : that word should not even exist in the first place! If one uses it in a sentence I become very suspecious on why someone uses it in the first place.

Darky 10.1 ROM's

Hi
1.
I'm using Darky 10.1 Extreme Edition
i read about the 10.1 Resurrection Edition and i dont what are the diffrences
especially in battery life manner
2.
when i flashed the rom i didnt wipe the device via recovery.
do you know if the ROM does it itself ?
and what are the diffrences between the wipes ?
3.
about Juice Defender
If i manage myself BT,3G,brightness, would it make any diffrence ?
in other words - does it good only for battery spenders or does it really improve the phone battery requirment
4.
do you think it is efficient to set my cpu UC to 600\800 MHZ when battery is low ?
i can do this with SetCPU\CPU Master
thanks.
I dont know about the first two, but with JD I manage bt, 3g and wifi myself. Auto-brightness included. I do quite a lot of texting, Nimbuzz and Whatsapp, and some calls. With JD I get about 18-21 hours
allright, and is it worth to buy the pro\ultimate version ?
JD doen't work on my sg1...i think it's only a funny app
anyone else please ?
Flash the Final rom with Battery life at 100% this resets the battery data, I have noticed a vast difference in battery life with Darky's 10.1 rc6.
1. From my understanding 10.1 Resurrection Edition is a done via Odin (and not flashed from CWM). This is the suggested method for those that have had some troubles with flashing via CWM and is a complete wipe.
2. When I flashed 10.1 about 2 weeks ago, I followed the instructions and all my applications were wiped (but data was still there, i.e. backups). I did not select any wipe option I believe but I was also going from 2.2 to 2.3.3 which I think wipes the apps automatically. The differences in wipe options are whether the apps are wiped or whether everything (apps plus data) is wiped.
3. I have used JD on and off. I say on and off because the control of data/internet access was sometimes flaky. I think the latest versions are better in this. JD is good for automating so less messing around with changing settings. Not sure on the pro versions. I would also try SuperPower as it is similar JD (JD is easier to use though) and gives you a feel of what JD is like. I do agree that sometimes it is easier to manually change myself but occassionally good to have this in automated mode.
4. I messed around with SetCPU but did not feel that it saved that much. This is anecdotal so happy for other opinions. I don't see SetCPU being referenced in the battery improvement guides. I've seen more issues with SetCPU particularly with the Galaxy S but this may be older versions. Also, personally, Darky's rom is super fast and noticed a little lag when operating at lower clock speeds which frustrated me more than the battery power issue so have uninstalled. I am trying again with 10.1 to see if it has improved.
Thank you for your answers.
I currently have no battery issues, but still looking for longer life, so ill be able to use the?phone heavily without charging it during the day. Is it worth to upgrade to the RCE for this.
BTW i flashed with 100% battery. (And calibrate battery anyway, just in case)
Well, i hope the 10.1 extreme edition wiped the device entirly by itself.
I don't find JD really helps much if you manage your wifi and 3G yourself
I don't think a full wipe will help much if you don't have issues. JD is pretty good but I found I was using the internet a lot so waiting for it turn on was a pain. I did feel it increased battery usage.

[Q] ROM with the best battery life?

Exactly what the title says. I've been looking here and there for some ROMs that I would like to flash and I found quite a number of them to try out. However I want to hear from the experts who have been flashing custom ROMs all the time. What would you say would be the best ROM on battery life? I am currently running Hyperdrive RLS21 and I'll say it does decent on the battery life albeit the standby time can improve (I lose around 10% in a night if I leave it 100% uncharged).

First off battery life is subjective and usually has very little to do with the ROM. It is the kernel and settings which usually have most affect on battery life amongst the same user. This is not something you can compare from user to user but must be compared by the same user under the same conditions.
Let me give you some examples..a heavy gamer will get vastly different battery life from a heavy phone/text user. A person in low signal areas that has many apps synching will get horrible battery life compared to someone who has very little apps or great signal. I think you get the idea.
Kernel settings such as governor/scheduler/OC/UC choices will vastly affect your battery life. You really either need to compare ROMs yourself, or find someone that has compared ROMs under the same situation and similar use as you to get any useful data. I see that you asked for opinions from those flashing many ROMs. Other factors can affect that too...were they all clean flashed? Were any adjustments made?
Hope this helps! And hope you find the perfect ROM for you! Happy Flashing!

Problem is that I'm on a locked bootloader (ATT variant) so it's only natural that I should ask for a ROM that could give the best battery life since I can't flash any kernels
I'm no expert but I've been flashing ROMs for my S2, now my s4 for last 3 years. I've found recently that Tesla has the best battery life, 4% drain over 8 hrs at night. Best ever

Battery life in different roms

Please post your battery life in stock marshmallow,stock nougut,RR,AICP and other roms.
So we can compare them.

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.
Sorry for my bad English. I hope you guys can understand what i am trying to say.

I understand this. But I think it would be easier to try for yourself, because to get say, me to try say 4 different ROMs, same usage, and then report back to you would be more time consuming than you trying for yourself.
I know you know that every user is different but the same user trying different ROMs for you just doesn't make sense.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

I am not saying anyone to try different roms for me. I was just wanting them to post battery stat of the rom they use as their daily driver.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

Well said!
@yk1999 As stated above as well as in my post, you just can't compare experiences of users across multiple devices and ROMs as there are to many variables involved. We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?

LG G6 9.0 vs 8.0 vs 7.0

Hi guys just want to ask in terms of performance and battery usage
what stock rom is recommended?
next question : best rom for korean variant?
For me it's definitely Android Pie 9.0 running it on a H870.
I factory reset, put animation to 0.5x and disabled location service.
Get easy trough the day with 3h sot and 50% left.
Of course all of it depends on your usage.
Camera still needs a lot of battery ?
For me they were identical
Slight software improvements here and there
but the speed and battery life was the same in all 3 versions
9.0 definitely. Smooth, energy efficient and one biggest improvement for me : Captune application form Sennheiser is finally working like it should. It was very unstable (basically unusable) under 8.0
For me 9.0 is a bit choppy after all updates installed and the phone went idle. But now i have oneplus 7 pro so yeah...
