Unlocking the bootloader - Sony Xperia XZ Premium Questions & Answers

Are the devs anywhere near TA backup? Should I wait or should I just unlock? Is it worth it?

Just wait because some people we make a big mistake this phone isn't like s8 there is not to much people who worked in this device so just wait
PS: I would like have my device locked again

Yeah, I'd say the decision ultimately depends on why you want to mod your device. There isn't much development for this device, and the two custom ROMs are either not going to be supported much longer (Turbo) or aren't working very well (Carbon). So, first you'd need to be good with manually updating your firmware, patching DRM keys, hoping someone still updates kernels, etc. Either that or your excellent camera goes to waste with green pics.
I wanted better sound and so, from that perspective I am happy I rooted and set up Viper. However, on the whole I'd probably not have unlocked my bootloader because applying security updates is time consuming and there aren't good close to stock options in terms of zip flashable ROMs.
Overall, I'll never buy another Sony device as the DRM key fiasco is utter bull****, and my specific device has a couple problems.

well, stock get sh!t battery and its not only me though.
yes with stamina its good but still I should easily get 6 hours without stamina, here I got stamina on battery perferred and still barely touching the 6 hour screen on time...
I litterally tried every thing, I think my battery is leaking XD because if i use my device straight I still get 6 hours without stamina mode enabled, but if I occasionally use it I still get 6 hours even less, because when the screen is off battery still going down like a b!tcH its like a sale you know? XD in 6 hours the battery dies wether you use it or not XD

Experience is definitely personal. My average battery use (presently 18 cycles on Accubattery) is about 8% per hour screen on and 1.5% per hour screen off. With the screen off I stream quite a lot of music, so I'm probably more like 1% per hour standby. Full battery estimates are nearly 13h screen on, 55h screen off and 30h combined.
I've typically been stock, but rooted with DRM patch. I tested Turbo for a short while but found the system UI customizations lacking, sound not all that great, and battery was worse.

[Q] Nexus 5 Sudden Battery Throttle

So, I don't know if my problem here in particular is unique or new, but this issue started about a week ago.
My Nexus 5, is rooted, and running Cyanogenmod 11, (was) running with ART Runtime, and I was getting pretty decent battery life with the phone. Usually nothing less than 2-3 hours of screen on time, with pretty typical settings (location off, sync off, etc).
Out of nowhere, about last week my battery life began to be much worse. It'll drain from full to 20% in a matter of 5 or 6 hours, and none of my usage really changed at all. I'm well aware of the mm-qcamera-daemon, but according to my battery usage page, it still isn't really in use or bothering my battery life.
What could cause this sudden change? I'm here at work plugging my phone in half way through the day, when normally I can go about 2 days without charging.
I've tried factory resetting, I've turned off ART, I've tried changing the governor on the CPU, and many other things. Is my battery simply going bad?
If anything has a solution for me, it'd be a blessing.
Thanks.

If i was on your place I'd return it back to stock and see how my phone would react. Afterwards if issue has to do anything with hardware I'd unroot + relock bootloader and give it to my provider for a warranty and explain them my problems.

Hmm..
That's not a bad idea. I think I'll flash stock back on to it when I get home tonight. You know, I have insurance on the phone, but I was expecting to have to exchange it for breaking the phone's screen, not for my battery going bad. I hope Stock ROM fixes the problem, or hell.. maybe whenever 4.4.3 ROMs start coming out, that might do the trick to. I've been careful to take care of this phone, since I broke my Nexus 4 two months after I got it.
Thanks.

You're welcome. I hope that you solve your problem as soon as possible. If you take a look how your phone does with stock on your diagnose of a problem would be much easier and from than on if the problem was in software you can try some other roms and kernels. I personally am not really a fan of cyanogenmod 11 at least not for nexus 5 since I've had few bugs using for a few days.

Well, I really liked Paranoid Android for my Nexus 4, and I've had no issues until recently with CM11. :\
I guess stock is going to be my best bet though. I just really hope I can deal with the battery drain issue from mm-qcamera-daemon or whatever.

I've been using SlimKat in combination with Faux's custom kernel for a few days now and I must say that peformance is as smooth as it was never before, speed is absolutely phenomenal and my battery life is more than pleasing (around 24H + 3-4 Hrs of screen on time).

Well, that sounds like exactly I want. I'm not opposed to trying another custom ROM either. Can you PM me a link to the thread with whatever particular build you're using?
If it's efficient and up to 4 hours of on screen time, sounds like exactly what I need.
I'm more than happy to ditch my ROM if I can get better performance, haha.

ROM: http://www.slimroms.net/index.php/d...4-slim-hammerhead-4-4-2-build-4-official-3700
KERNEL: http://faux.romhost.me/hammerhead/kk44/
I'm using non-ultimate version of the kernel which means that it doesn't support overclocking and I'm also using a bit older build which is very stable and works flawlessly for me.
Ah, great. I'm actually going to download it now, while I'm here at work. Also, does this particular ROM work at all with ART Runtime, because if possible, I'd like to continue using it.

It does support ART. I didn't try it on this ROM though so I cannot tell exactly whether it's working or not. You'll have to test it by yourself but I am pretty sure that if your phone doesn't have any hardware issues that you won't be disappointed with the performance of ROM + Kernel with or without ART! Hit thanks if I helped you anyhow :laugh:
PS: Though since the ART is still in beta phase of development there is a possibility that it has caused you so much trouble with battery =)

Batteries Can't throttle. However the do degrade with use. You can replace the battery with ease.

New phone battery life

Hi!
I am new to the nexus 5 community and I just got my nexus 5 about 2 days ago
After fully charging it I started using it , I have heard that nexus 5 has battery issues and that's why I only want you people to help me tell how the battery life of my phone is for a brand new device by seeing the screenshots of my usage.
Here are the screenshots:
Looks normal to me. What's ingress? A game?

Not bad. I would disable Wi-Fi always scanning available (even if Wi-Fi is off), location to start. That's not bad though and is about what I get, but you might be able to get better SOT.
the nexus 5 does not have battery issues, at all. it stupid people that themselves have issues, not the phone.
Seems normal to me ,I bought mine month ago
There are no issues with battery on nexus 5. I charge mine usually once in 3 days, my record without charge is about a week.
It really depends on how you use it. Under constant 100% load I think battery can be depleted under 5 hours, as in every other device.
i can use my phone very heavily, and deplete my battery in 6-8 hours. but ill still get 5+ hours screen on time.

Have you tried running the phone down till it switches off? I know it's not good practice to do that often but I like to do it with a new phone relatively early as it makes sure it's calibrated - sometimes phones can either switch off at 5% or, conversely, run on 1% for hours...

You don't ever need to do that as it calibrates every time you charge the phone. Also he just got the phone and isn't having any battery issues.

He means to break in a LIon battery the first three times you kill the battery and then don't take it below 20% after that.

That's not helpful and does more harm than good. Li-Po never needs to be user calibrated in any way.

Thanks a lot guys for taking your time and helping me , nexus 5 is truly an amazing phone.
@Ben36 yes , ingress is a game and its a location based so it keeps running in the background and uses location services.
Guys , I have some questions relating to the vibration motor , is it fine if I ask here or am I supposed to make a new thread?

I was just about to start a thread about something then I read this. So here's the deal. I agree that it's almost always user error and/or over expectation when it comes to battery. Stupid people are here to stay. I'm neither stupid nor expecting too much from my battery.
I've always been intrigued by how some experienced users get great battery and some get not so great. Has to be user error I always thought. I thought this because I was one of the experienced users getting great battery life. I mean GREAT. Way over 7 SOT all the time.
So a few weeks ago my first phone had an audio port issue that I had RMA'd. I received the new phone and set it up. It had crap battery. I'm talking less then 2 hours SOT. Same ROM, same kernel, same apps, same coverage for mobile and data, same usage. I set about looking for wakelocks and they all where the same as the first phone. Nothing was wrong on my end. I spent over a week troubleshooting. CPU frequencies and time in state where normal. Temps where normal. CPU benching was the same. Awake vs screen on was almost identical. The phone is sleeping like a baby when not in use.
So, using Occam"s razor, it would lead me to believe that not all batteries in the N5 are created equal. After getting off the phone with a google support supervisor a few hours ago he agreed. Another RMA process has been set up and I was promised this phone would make it's way back to LG so they can actually analyze the battery.
Like I said, I used to think the same way you do. Now I'm not so sure.

oh, no, I 100% agree with you. just like our devices, that all aren't equal, that are all assembled in differing places, that all have smaller parts that are made in more different factories.. the batteries themselves will differ as well. it'll even probably fall onto a bell curve, where most are near the center, and less with better or worse. but 100% they vary.

Well I feel that there are always some exceptions , some phones may have a manufacturing defect and maybe the phone you are talking about did have one , but these manufacturing defects are mostly really rare.

I was just explaining what he said. The rumor is (supposedly backed up) that you kill the battery 3 times in a row but never take it close to dying after that and you get the best battery life possible because the battery works best if you only charge it between 20 and 80%. I think there may be something to it because new phones only last like half a day on the first charge but after a week last a day or longer for me. I won't derail this thread though as that's a debate that always loves to go on and I've never found hard proof either way but people who just write websites who supposedly sound smart and can word it quite eloquently.
That being said, I didn't necessarily agree with it, but I was clarifying what was said.

Thanks for clarifying. Keeping the battery between 20% and 80% is said to help with battery degradation, which after a year or two might affect how much one could get out of a full charge. Most won't find it practical to limit them self to only 60% of their total available battery pool though.
Even hitting 0% isn't as big of a problem as some may think as there is a reserve charge for protection. For instance, mine has full died on me twice due to a power outage (I even attempted a boot up) and I always full charge with no noticeable degradation after 8 months.

Don't worry about battery life until 2 week after !!!!

Hi everyone , I'm new in the community but I already found that this is one of the best phone forums online , normally you come here for help because you have a problem right ? But today I'm just here to give an advice, I notice that many people complain about the battery life on their new phones , I had the same issue with my note 5 , I saw a video on YouTube and the phone showed an estimation of battery usage of 18hours while mine only showed 9 , I immediately thought that my phone was broken or something until a month later I realized that I was getting more than 20 hours of battery usage , when we use a phone for the first 3-5 days ( specially android) we can't expect it to be fully optimized because it's still learning your behavior and phone usage, just by installing a new app your making your phone to "learn to do something new" when I got my s7 edge I didn't expected to have great battery life , I was constantly installing and removing apps , flashing Roms and trying themes and etc. Now after a month later I use my phone on a pretty standard routine , I used package disabled but it only made my phone laggy and slower , so I decided to use my phone on the stock way , I running all stock , ( only disabled the apps that come with the phone that I don't use like power point , Samsung gear and health...) and after I did this I noticed a huge bump on battery life , I went from 12 hour of usage and 4:30-5hours of SOT to 30hours of usage and 8hours of SOT
After installing a custom/stock rom make sure to drain the battery completely just once to calibrate it !
I can never get more than 6 hrs sot.. Gonna follow your tips and write back in a week or so. Thanks for sharing!

Feel free to use package disabler, it was a lifesaver to me with my note 5 but not on the s7 , but other users report that has been really helpful other thing you could try even that the impact will be minimal is using a dark theme ,
Also don't update to the newer firmware if on Exynos. Seems to hit battery life by 25% or more as android system goes from around 5% to 15-20% battery usage.

with newer firmware you mean the may update?
with me it was the other thing around, in the beginning it was quite good but now, its worse. is it because of the bright sunlight or the phone getting hot because it was around 30 degrees almost?
you see...screen on time about 2 hours
most active battery drainer, android itself
Only way for me to get 4 hrs of sot i have to plug in to charge and disconnect before i get to 90 cause then it seems to thing its fully charged and battery meter resets (on battery).

The thing is, I have disabled half of the system already, but it just feels like it's doing even worse than before so I'm leaning back on running stock again.
Yes original firmware much better battery than the update

It didn't work either to me , this is what I think , it may sound stupid but it could be the true cause , I think when you use an app like package disabler to disable things on your phone and then you accidentally touch to open the app or setting disabled the phone will think "what's going on here" why is this disabled? And it maybe tries to access/ open the package again and again causing it to actually drain battery !, You could a cache wipe , it worked for me , I follow all guides to extend battery life using package disabler, custom rom , flashing zips to delete bloatware but none of them worked for me , instead I went all stock ,and after installing the stock rom I did a factory reset and them the cache wipe, it worked flawless to me , the phone now works like a charm , no overheating (maybe I don't feel it because I got a case ) but the point is try to find your own solution , every s7 edge it's unic, maybe a simple reebok on your phone could resolve all of your problems , and a very important thing !!!!! If you flash a rom /kernel make sure you let your battery drain completely just once to calibrate it!
I wiped nothing, stock rom latest APD1 , aod off now but on sometimes , location on, sync on 3 emails, disabled a few things with ez package disabler. Browsed the net for all the time the screen was on, WiFi on while screen of and on for atleast 2 hrs while using line messenger and used Spotify for around 30 to 40 mins. This is sot and battery usage.
I don't know how u manage to get such bad battery life, swear u guys r fu#*ING about with sh%t too much, let it settle.

Great battery life , you can easily achieve 3 days of battery life and 8-9 hours of SOT I guess which is great for you , just consider yourself in the 5% of people that own a phone with no battery issues , I'm happy with my 8hours of SOT and I could achieve 3days like you just by using WiFi, I use LTE because it's faster were I live but remember that there are people so disappointed with their phones because they want to get the most out of their phones and just can't, may I ask if you are amazed with your battery life or do you own other device that beats the s7 on battery ?
I am amazed, it's as good as, if not better than my previous phone the z3, which was running a custom rom and kernel.
I do consider myself lucky to have the phone run so well right out the box.
Also when I said alot r fu#&ng around with their device, I meant roughly the same as you, I didn't mean to imply their problems r not actually there. I meant as u had said, changing roms, removing apps for new, disabling apps, not letting anything settle, wont give good results in battery life.

I wiped nothing, stock rom latest APD1 , aod off now but on sometimes , location on, sync on 3 emails, disabled a few things with ez package disabler. Browsed the net for all the time the screen was on, WiFi on while screen of and on for atleast 2 hrs while using line messenger and used Spotify for around 30 to 40 mins. This is sot and battery usage.
I don't know how u manage to get such bad battery life, swear u guys r fu#*ING about with sh%t too much, let it settle.

Holy smoke, 5+ hrs sot in half of battery. I've been trying to get more than 6 hrs for like a month now with different roms and optimizations, not even close..
I hate to be the voice of cynicism, but we do need to stop this stuff somewhere. The original post is utter nonsense. The suggestion that phones 'learn' your behaviour just simply isn’t how kernels work. There's a very small degree of 'learning' but power management is a very reactive process based on exactly what's happening. The only thing new apps change is what processes are running, and the kernel will instantly scale to do what it 'thinks' is right. Some managers will observe processes for a bit longer and react based on that - but we're talking hours at most, NOT days.
The only credit I'd give to this idea (which seems to be all over XDA for some reason) is that the first few days people use their new shiny phone a lot more than usual, and probably also more than they’d think. They also become far more aware of battery life and will even turn on the screen just to check battery life, which will obviously accumulate batery drain - so the bit about using your phone more is certainly true. But anything about Android being some sort of AI Neural Network app learning extraveganza that learns what you do over several days is (for the most (significant) part) wrong.
Think this is just descending into another battery thread and we have one here already

Huge battery drain !!

I am facing a huge battery drain while on standby in my Xperia XA. .
Its draining around 35% - 45% overnight doing nothing! Anyone else having the same issue ?

Is stamina mode on and set up properly, is background data disabled. Auto sync, location in GPS instead of battery saving ect are all things that will drain battery try doing a factory reset or software repair both can work wonders when you have problems. It's more likely one or a combination of the above and to much running in the background

Tried factory reset and checked all of the above settings things seem a bit better now. Meanwhile checked in Sony forums, there seems to be a WiFi bug which is causing this. Someone from Sony has also acknowledged this. Hopefully this will be resolved in a software update.

Yeah I Saw that gonna be fixed in a update, wifi always scanning needs to be turned off till then, how are you finding the xa apart from that seriously looking at replacing my M2 with one in a couple of weeks I just hope it doesn't get left behind being a mediatek powered Xperia if I get one.

The overall performance is above average given the near stock Xperia UI. Maybe its not as good as SD 650, 615 series, but it still is manageable. Few sour points like free space is very less, 2GB RAM(but RAM management is pretty good), battery life and lots of bloat in my region atleast. The camera and the display are the plus points. Even though it has a 720p, colours are more vivid and sharper than most phones. The brightness levels too can move from very low to very bright.The design feels premium too with the edge to edge screen. Finding a tempered glass to cover the entire screen edge to edge is bit difficult though. I would suggest go for XA Ultra if possible.

My network only do the x,xa,m4,z5,z5c and z3 i was going to get the x but even on a contract they want to much a month and expect me to pay towards the device(not gonna happen) which leaves the xa as this would be a free device or a honour 7 also free which looks good but I don't like the ui and no app drawer and the xa spanks it in antutu benchmarks and I'm a Sony fan anyway just gonna take some getting used to not having root as I refuse to unlock the Bootloader on a Xperia device and lose all the things you buy a Xperia for to root it. Next two weeks can't go fast enough

Agreed. Its best to stay away from Honor. Here in my country XA Ultra is not even available and Xperia X with inferior specs is more expensive than the Z5. Certainly this is what's wrong with them. They are talking about de-focusing from certain markets. Don't really know where their focus is. Hope they get things sorted out. Their design is just so good. Its so ironical.
I wait for an update to fix the problem !

Yes I have already done this. WiFi is still draining the battery but it's weird the battery is getting better day by day.
Its lasting for more than 24hrs with moderate use now with around 4hours of SOT. The only difference was that I have inserted sim cards. Previously there were no sim cards. Could that be the reason behind the drain?

It probably didn't help the situation having no sim card inserted. The more you use it and charge and discharge the battery the better it will get it may take a week or could take a few weeks to reach its maximum screen time ect. 4hrs sot ain't to bad for a device twice as powerful as the m2 with the same size battery more or less. I usually get between 4.5-6hrs sot depending on how I use it on my m2 I'll be expecting at least 4hrs sot when I get mine on a stock device that is. More than that on a rooted device if root is available that is. I looking forward to getting this device to be honest even if it is a mediatek powered Xperia

Yes the battery has settled after a couple of discharge and charging cycles. :good:
Yet the whole threat is useless.You cant change how the battery / OS is acting, WITHOUT unlock and root access even new custom rom.I lost like 2-3 days in searching for solution of my problem , to find working guide to unlck the bootloader.
The only possible method to save your battery is by using GREENIFY. Using it on my htc phone for like 3 years, with personal score of 30+ days without recharge (STANDBY). Greenify works on root device, that cant happen on this phone ,yet.
PS: i've used some tools like - http://developer.sonymobile.com/unlockbootloader/imei-verification/1d2ac140b78501316d82b5e787350b76/, Flashtool, without luck.

Utter rubbish, and this device is still to new development takes time and someone who knows how to build working recovery ect. If this device has drm-verity which i do believe all new Xperia device's have since z3+/z5 locked Bootloader root will not be possible unfortunately. I'll know abit more when I get mine next week hop, my current M2 device is heavily modified but it doesn't look good for locked Bootloader root from now on.
I am starting to think that there are some other issues here other than wifi. I think the phone struggles to hold/find signal as my cell standby usage seems really high to me. I've noticed that when at home and the phone is on wifi my battery seems to last for ages. Its the second highest user over the screen.

My battery hardly reaches 3 hours onscreen, normally just more than 2 hours with very little usage, just facebook and around 15 minutes of boom beach over wifi. Even when I've already turned off the wifi scanning it still drains a lot idling. So I don't think turning off wifi scanning is the proper solution to this at all.
And yeah I think hpsauce37 has a point since I've been experiencing really weak mobile signal that leads to disconnecting my call automatically sometimes. And the mobile signal indicator just stands there at 2 bars at the same spot where my Xperia P shows a full bar.

U got 2 options to dissable WIFI scan.Look at the settings.
just to share, by disabling scanning wifi the device still scans for wifi when i switched off the wifi (i know it is a bug. im running build .35)
however, i have reduced the battery drain by 30%
-uninstall facebook (which is 99% running in the background)
-activate stamina mode (always on)
-switch off location service

Worth rooting? Can it improve my battery life?

Hey guys! Been getting around 4h SOT as highest on my device, AOD turned off, 30-50 % brightness, fhd+ and dark theme.
Can get through the day but can't get a minute more than 4h sot which seems weird.
It's not that I think the battery life is absolute ****, I'm okay with it, the thing that sort of "bothers" me is that i see people getting like 6-10h SOT on like 2 days of charge which seems unbelievable to me.
Now on to the question,
is my utterly **** 4g signal preventing me from reaching 6-7 h SOT or is it just that I'm "unlucky" with the battery lottery.
Is it fair to expect a 6-7h SOT if i do decide to root and flash something like a notorious kernel and a rom?
Which I know will permanently void my warranty.
Or should I return the device and swap it out for either another s8+ or something like a g6?
I hope I don't seem too much of a brat ****face but I did lay out tons of cash for this phone, which other than the battery I am incredibly impressed by.
Thank you guys for keeping this forum running, it's been a lifesaver!

Most of these 6-10 hours of sot is nonsense as most of these people don't even use the phone properly only leaving the screen on so that sot would increase rather than using it properly like watching YouTube having a decent brightness etc... Just use your phone as much as you like stop thinking about battery life if it's really a problem get a powerbank. Me my self if I'm at work I use a lot of GPS as I need to travel and I have my screen turned of as I listen to Google maps rather look this will put me at around 3 to 4 hours of SOT or more sometimes depending how much I use the screen. But when I'm at home I use the phone non stop and I get around 5 -7 I always use full brightest all the time full res gaming sometimes youtube etc as you can see the people who get 6 to 10 they don't even use the phone that much so is there a point for them to have this phone if they don't use it to full potential no they might as well get a cheap phone.
Edit:
The only reason I would suggest rooting is if you want to play around with the phone like having a different kernel that allows to change voltage, speed etc

This, i can get 20hr sot on my mate 9 if i leave it with screen on, take in account SOT means NOTHING, it just one measure that can be easily manipulated.
I use my phone the way i use and i only judge by the end of the day, how much perfect left and what took the most of my battery life, without caring about SOT at all.
Just now i was traveling to Budapest and made ton of photos and videos with my DSLR and the Mate 9, on sunny days your brightness will be up, shooting 4K videos and taking pictures, using GPS google maps, will make your SOT low, does that mean your battery life is bad? NOT AT ALL
Stop caring about sot and use GSAM monitoring up to understand if there is a rogue app.
I have the S8+ and I see that they have figured out how to root the Snapdragon version. I am not really pressed to root my phone.
The 1st time I used the phone, which was a weekend and mostly WiFi, I got over 6 hours of screen time. However on my work days where I use mostly LTE service and I'm inside an office building, I may only have 3-4 hours of screen time but I will make it home with almost 50% of battery life.
I'm no longer concerned with screen time. If my phone can get me through a full day, then I'm happy with it.

Firstly,
I fully agree with @Derpling post above .( His last paragraph..)
Also SOT, now days, means nothing to me.!
Many years back, i used to be obsessed
with benchmark, battery usage, performance etc.
I also use to root all my device's.
However, presently i have stop been " obsessed"
and accept what is reasonable/acceptable.
eg. battery usage including SOT.
prefomance and stop rooting.
There is plenty work arounds available.
Presently, what i do
is i have a few good battery
apps... Betterbattery, Wakelock detector,
Gsam, I enabled these apps with ADB, to get them working. No root. (Very straightforward one or two liner commands, that's all.)
If i have a rogue app, and my battery use " suffers" i use these apps to id the app. and sort app out accordingly.
eg clear cache /data or uninstall.
Lastly i read online that presently,
more devs are
using " other alternatives" than root.
eg ADB...
to give you similar end results.
Bottom line... I found that in most cases
rooting a device just
creates other/more issues.!.. to fix.!
Now days, for me to root my device ( if ever again)
i must have a very, very good reason to root.
Good luck

You so right about root, there is a workaround to everything tbh, i use the Mate 9 without root and it's the closest phone in my opinion to perfection, no tweaks needed.
Geekbench SOT all of it are just numbers as it means nothing.

I think this is your problem, not the battery. One of the biggest battery killers on any device is a weak signal as the phone will push more power to the radio to try and find a better one (not exactly what happens, but there or thereabouts). Rotting won't change that.
Have you tried switching to 3G only, does that make a difference? Does it differ when you spend time in an area with a better signal?

The problem with my service signal is just temporary, I've been working for the summer but I'm moving back to the university tonight, there I have full 4g and 3g signal so hopefully this will change, however I have settled down a bit with the phone and I'm pretty happy with the battery now, 4h sot is not bad
yea rooting aint the solution
try gsam, wakelock detector, etc to detect the rogue app
imho you don't need root to improve your battery life, i'm achieving 5hr SOT easily with brightness 50%, AOD on and resolution WQHD+, all you need is to disable some of the preinstalled packages, do a bit of research to find out which ones can be disabled without a risk, then you will be good to go pm me if you need an assistance
I think your battery preformance is most likely to some apps or how you use it, I can say from expariance and experemanting with my S8+ that SOT and battery over all can shift.
I haven't rooted since im using samsung pay and haven't had a real need for root yet. but have tried a couple of diff apps and tests to max my battery but found that non off it really saves battery, quite the opposite.
I have tried substrantium to go all black in the phone (cus we have Amoled) but my battery life got worse
tried nova launcer to get some preformance boost and also black down the theme, but nova still suffers from battey drain issues (had same problem with my HTC10)
have disabled alot of services like bixby etc with BK Plugin. but made no big diff.
So after having the phone since launch and mixing and matching stuff to see if I could squeese a little more life out of an already good phone, I got to conclution that Samsung has done a good job in optimizing the S8+.
The stock launcher is fast and efficent, the built in "cleaning" program works well in shuting down unused apps etc. and running the phone with no extras and not tweking anything special or trying to get the phone as black as possible, I can go about 2 full days with normal use.
If you have the Snapdragon, battery life will decrease, by 20%.
I switched from a Verizon S8 to an unlocked S8+ and imo not having any of the added bloatware makes a difference. On my S8 I could make it through a whole day but my battery would be down under 10%. I know the S8 plus has a bigger battery but I go to bed with 30-40% of battery life.
I run my phone starting at 4:45am with a gym work out and I'm in bed by 11pm. My usage is mostly lte except for when I'm home. My SOT is always 5 hours or more.
