Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.

Hi everyone
So I recently got a S2, upgraded it from stock Gingerbread to stock ICS via Kies, then flashed CM9. CM9 was great, but I quickly noticed worse battery drain than that of GB. I sorted out all wakelocks, now facebook is the top one in better battery stats list and it's only 10mins in a day so I don't think that's a problem. When charging, vbus_present shows up and keeps the phone from sleeping, but that's a normal thing when the phone is plugged, right? CPUspy shows the phone is in deep sleep the majority of time I don't use it, so I assume I have no wakelock problem.
But even then, the battery still seems a bit bad. When in deep sleep with wifi and mobile data off, it would lose around 1.5% per hour; and with moderate/high use (internet with wifi or gaming), I'd be lucky to have it last 3 hours. Charging to 100% from zero takes about 3 hours.
I also tried recalibrating the battery through BC, but haven't noticed too much of a difference.
Recently I found a guide on disabling fast dormancy via the build.prop file. Still waiting for results though.
So, my questions
1, My battery usage seems normal, doesn't it? 1.5% per deep sleep hour is acceptable I guess, but 3 hours of usage seems a bit short. Too short.
2, What effects does fast dormancy have?
1) Totally unacceptable. Mine lasts at least 7-8 hours with high use..
Does your phone heat up while the heavy use ???
What brightness level do you use for the display ???
How many apps do you have that can gain internet access ???
2) By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.
Luckily, Fast Dormancy can be disabled on the phone. For the Galaxy S II, do the following:
Dial *#9900#
Press “Disable Fast Dormancy“
Press “Exit“.
Easy as that!
Thanks for the suggestion I have brightness manual and at around 20%. Wifi is disabled when not used, and mobile data is always turned off unless I need it, so basically apps only get internet access when I want them to. I have also disabled sync for both google and facebook, but fb still pushes notifications to me while it's connected. Is that a major battery drain, and if yes, how to disable it?
Anyways, facebook, instagram, youtube are the only apps than can access the internet. No messengers or anything that may keep a wakelock.
My phone doesn't heat up during normal use, maybe a bit when I do some gaming (Max Payne?)
Also, *#9900# doesn't do anything on my phone. It doesn't bring up a menu or anything like that.
Bump. Guys?

Install BetterBatteryStats (search for it on here/Google Play), might help you nail what's causing the drain.
Yes I did, as said in my original post. After a night the highest wakelock are just around 10 minutes, and that one was facebook. Uninstalling it however had no effect.
Delivered using Nyan Cat's rainbow powers.
Thinking logically, there's got to be something else in those stats (partial wakelocks in particular) that's causing that drain. There's no way having fast dormancy enabled/disabled is either going to cause/fix the drain you've mentioned getting '3 hours of usage'; (I can get 5 & a bit hours screen on with CM9 & variable usage/mostly 'moderate' use) given everything else you say you've tried.
Post BBS logs here if you want someone to have a look.
Edit to add - Also post a screenshot of the 2nd screen in settings/battery, the one that has history 'details' at the top, with the 'mobile network signal' bar underneath the main battery graph.
Here you go: pastebin.com/1UwicChJ
I just registered half a day ago and don't have enough posts yet to paste links, so sorry the phone was only on battery for nearly 2 hours with some light browsing and facebook, but I hope it works.
Anyway, I looked through my running processes, and dsp manager is the only non-OS process running, besides facebook. I got CM9 so it came by default. Could dspmanager be the culprit?
Delivered using Nyan Cat's rainbow powers.
It's a new phone he's got there and I doubt it could be anything battery related itself.
I'm using CM9 nightlies and I get around 9 hours moderate use. It has been said though that a lot of these CM9 builds have battery drain and heat issues.
I use Juicedefender to help with the battery life which seems to work.

About 1/3 of this time was on wifi browsing. The drop is much more drastic if I play games.
Delivered using Nyan Cat's rainbow powers.
A couple of observations. There's nothing that stands right out in the BBS log. The other one is, looking at that graph you've lost ~15% over a bit under 2 hrs. The screen has been on most of the time the phone has been awake (confirmed by the BBS log) if you look at the respective bars. You've also been using WiFi for most of the time the screen has been on/phone has been awake.
Roughly speaking, going by the screenshot, you'd get ~5hrs+/- screen on time if you kept using the phone in the same way you had during that just under 2 hrs, and this is pretty much normal. I haven't had drain issues for ages, so I double checked my details on the 2nd screen of settings/battery to make sure CM9 is reporting these details accurately (screenshot attached). Certainly in my case, this screenshot reflects what my phone had been doing for the just under 5 hrs it had been off charge/since last reboot; that is, >90% of the time in idle/deep sleep. So it probably isn't CM9 reporting these details inaccurately in your case either.
The BBS log & screenshot don't illustrate the problem you talked about in your OP. Now, if I had to take a stab in the dark at what's causing problems when you do have them (and FWIW, I do believe you're having the problems you mentioned in your OP at times), in the absence of any other info, maybe your WiFi router is constantly sending the phone packets (what's been referred to as a 'dirty router' on here before) when you're connected to WiFi & not actually using it. This scenario has been known to cause relatively high levels of drain.
So to be honest with you, based on that screenshot & the BBS log, I'm not really seeing a problem.
Now, if you want to post the same again when you actually have a problem with drain similar to what you described in your OP, happy to have a look at them. But for that ~2hrs covered by the BBS log & screenshot you posted, that's pretty much normal.

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD
Nah. Anything with screen on is far from 'light activity'. Screen consumes far & away the most juice. In saying that, I've seen some people on here say they can get 8-9 hrs screen on with 2000mAh battery. How they do it I have absolutely no idea.
But if yeah, 5 hrs with the screen on most of the time whether browsing or playing games (games in particular are very CPU/GPU intensive & thus use a lot of zzzzs; unless they're really basic games like chess or similar), or anything else isn't too bad. Can you do better ? Obviously, if people say they can get 8-9 hrs. But it's not a matter of doing A, B & C and you'll magically end up with massive screen on times. Every phone is setup & used differently, and getting the absolute max out of every charge takes a lot of trial & error and experimenting with settings/setup.
There are tons of threads about the subject on here if you feel like going down that path. For me, I'm happy with the battery life I get these days because you can really obsess over it & spend a lot of time stressing over it/trying to maximise it for often very little gain. I'd rather simply use my phone a lot during the day & charge it at night.
Yeah Crackberries are like Japanese cars, they can run on fumes pretty much ;-) Having a dual core processor, a decent GPU & a huge screen kinda changes things.
There is one thing you can do fairly easily tho. And that's to make sure the phone spends as much time as possible in deep sleep when you're not using it. That will ensure that you have enough juice to get you by when you do want to use it. Simple ways to help achieve that is to turn off data/WiFi completely when you're not using it (tho many people don't like to do this for different reasons; which is perfectly OK if you're happy to live with the resultant drain), and make sure you've got no apps that are doing things they shouldn't be doing (like syncing, for example) while the phone should be sleeping. Again, there are lots of threads about same if you ever feel like a bit of light reading ;-)
So yeah, if you do find you experience drain that's not normal/outside the usual pattern you have, definitely post details & people can have a look for you. And as you said, you'll get to know what really is normal with regard to drain & so on is as you use the phone more (I tended to use it constantly for that first couple of weeks as well).

Already took such measures. Wakelocks killed my battery over my first night with the phone, and I woke up after 7 hours to find a ~50% battery completely empty. Now things are alright, I clear CPUSpy stats before I sleep and wake up to around 95% of deep sleep time. Overnight drain varies between 5 and 10%.
And yes, yes you are right. Maybe I should stop going nuts. I'm checking BBS and CPUSpy every hour, reading every XDA thread on battery, and calculating my battery drainage every morning I wake up :laugh::laugh::laugh:
Re: dirty/'noisy' WiFi networks, have a look at this post as an example of what I was talking about above.

Umm...so I just woke up, and noticed a wakelock in the kernel category. It was PowerManagerService, and it occupied around half an hour. Overnight, aftet I've slept 10 hours (got a day off ), my battery came from 24% down to 13%. That's a rate of roughly 1% per hour. Is that normal? And also, what is that PowetManagerService wakelock?

I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??

Hi all,
I am one of the many people complaining for the very poor battery life of the Exynos S9+, but my problem is more extended.
In the previous days I read all the topics related to battery drain in the S9+ and S9 sections of the forum, without finding any solution
My problem is very strange: every Samsung Galaxy I owned (S6, S7edge, S8 and now S9+) has a standby drain around 4%/hr. This is very bad, since more or less 60%-70% of my battery during a standard working day is drained without using the device. In 24hrs I can reach 0% battery with a few minutes of SOT.
I tried to disable almost everything (AOD, sync, location, google location history, nearby wifi bt search etc), hard resetted the device and started from scratch, but the standby drain is always the same.
The very strange thing is that if I configure with all the same apps and accounts a device which is not a Samsung galaxy I have maximum 0,5%hr standby drain. I tested it recently with Lg G6 and Xiaomi MiA1 and the drain is not present. Again, same apps and same setup of the phone.
There should be something specific in the configuration of my Galaxy devices that causes drain, but in 3 years I couldn't find it.
Is there anyone who can help me? What am I missing?

No, I will try today thank you. But for the most part of my day I am not under wifi, I am under 4g (full bars), so it will have effect only on the few hours I pass at home with the wifi connection

Ah ok, then this will maybe not help too much. Whats the battery usage percentage of your android system? Please add a screenshot of your statistics at the end of a battery cycle.
This is one of the best battery cycles of the last days:
12h 50min since unplugged
16% remaining battery
2:54 SOT
3,2%/hr standby drain
More than half of the SOT done under wifi during the evening, from 8:30am to 18:00 under 4g.
This is a terrible battery life, I cannot get to the end of a working day.. And this was one of the best days. Sometimes the standby drain is more than 4%/hr

Nothing obvious jumps out but that does look worse than normal, are you travelling around/ in bright sunlight a lot?
Few things to try -
1) Download betterbatterystats and enable through adb commands
2) what was the screen brightness like on GSAM?
3) factory reset did work for me
Something is wrong.
Do you have any apps running in the background all the time ?
Or dozens of accounts syncing?
Does your phone actually go into sleep or dozens mode ?
Do you have running bixby or google Assistent on ?
Do you use Iris scanner ?
Thanks for the support. I also have yesterday's screenshots of betterbatterystats, here attached.
It seems to sleep a good percentage of time.
No, I'm not traveling, I stayed the whole day in the office.
Accounts : Google, Facebook, WhatsApp, Twitter.
Yes, intelligent face scan is on
Same here i just bought the phone a few days ago. Disabled bloat and still i cant even get close to 24hours max apx 14 if i dont touch it. My Old S8Plus was so much better. Going to try a factory reset in the next few days. I must admit i did restore from a previous backup.

Facebook is a known battery hog, please try to use the official lite app from facebook. Intelligent scan always activates the iris scanner as soon as you turn on your device. Do you use your lockscreen alot while not unlocking your phone? During this time the iris scanner is wasting energy cause it constantly scans for your eyes. I have setup my device to start scanning only when i swipe up on the lockscreen.
Whats with that 1h20min of Google Play services. Did you use the playstore or some other stuff from Google for that long amount of time actively?

I will try today to remove Facebook and install Lite (the strange thing is that with my LG G6 and MiA1 with the official Facebook app I have zero problems).
Iris scanner and lockscreen are almost never engaged. The phone is sitting on the desk, and I wake it up through fingerprint most of the times.
Now here in Italy it's 11AM, the phone is unplugged since 7:30Am and the standby drain is already 4,5%/h

My problem is very strange: every Samsung Galaxy I owned (S6, S7edge, S8 and now S9+) has a standby drain around 4%/hr. This is very bad, since more or less 60%-70% of my battery during a standard working day is drained without using the device. In 24hrs I can reach 0% battery with a few minutes of SOT.
I tried to disable almost everything (AOD, sync, location, google location history, nearby wifi bt search etc), hard resetted the device and started from scratch, but the standby drain is always the same.
The very strange thing is that if I configure with all the same apps and accounts a device which is not a Samsung galaxy I have maximum 0,5%hr standby drain. I tested it recently with Lg G6 and Xiaomi MiA1 and the drain is not present. Again, same apps and same setup of the phone.
There should be something specific in the configuration of my Galaxy devices that causes drain, but in 3 years I couldn't find it.
Is there anyone who can help me? What am I missing?

I have an S9+ Exynos since launch, and even when at first it came with some drain issues, those and many more were addressed with latest update (BRE).
From what I can see, you are using 2 SIM's and your signal is not that good, which contributes to the battery drain.
Other question: how are you doing the backup/restore of your things?, because the S9+ is known for being picky with these, and if you don't do it properly, it will impact battery and application behavior.

Is better if you can try a clean installation and remove/disable the things you don't use. I'm able to get +5hrs SOT in a period of 40-48hrs constantly; I recharge my phone every 2 days and the battery drain overnight is around 3%. I'm all stock, no root or ADB tweaks, and the only thing I don't use is AOD because is not useful for me.
Also I know many other people with similar results as mine, so is a matter of configuration or your phone is defective and you would need to change it.
Good luck!

Hi,
My main problem is that I have the same exact problem with the S8 and S7edge, but not with the LG G6... so it's something related to my configuration on samsung phones (same account, same apps, same everything). That's the reason why I'm sure that the phone is not defective.
I have the same problem if I use it in Single sim, and 90% of the day I am under full bars of 4G+ coverage.
The configuration started from scratch (did not start from previous backups). I had just setted up my google account and then reinstalled everything from play store. The only backup I recovered is Whatsapp (through the internal backup function of the app on google drive)
Thanks to everyone for the support!
Facebook Lite: no results. Still at 3,5% standby drain per hour.

Try to disable background activity for "Android System".
For some people, this helped a lot.

Which are the implications of this choice? What will I loose?

Has no implications, it seems that for no reason that option drains a lot of battery for some, so maybe you want to give a try.
Everything works perfectly with it disabled, I run this options since I got my S9+ and is day and night difference.

Does this option stick on your phone? Its activated on mine again after each restart.
I have the S23 Ultra since February 3rd and battery life gets better and better.
I don't know what to say. I think this s23 ultra is faulty. I can't be at 29% battery used with over 6 hours screen on time! Light use, from 80% charge
15 hours total uptime, 8 and a half hours screen off time, gotta sleep sometime. LIGHT performance profile used and screen at 60hz cause 120hz my eyes can hardly see. It's smoother yes, but barely, battery life is king for me
All on WiFi, location on, most apps sleeping. Gobsmacked. It's beating the redmagic 8 pro that's in the household with its 6k mah battery.
I'm expecting a lot less using mobile data, surely

Amazing battery
This phone is perfect
Got it since February 10th in the USA and I can only say battery has been great. Compared to my other phones ( coming from a pixel 7 pro and a Xiaomi mi 11 5g) the battery life is just excellent on this s23 ultra, for such a big device and huge screen size I think Samsung finally nailed it. No sleeping apps, not profile settings just plain stock and so far so good. Wifi and data on 24/7, location on 24/7, VPN 24/7 . The browser times where spent a huge time watching videos from it, almost an hour of video calling and shooting some video and photos, couple of sessions of gaming.

How much do you lose on standby? Say overnight, while sleeping, over 8-10 hours how much do you lose ?
My last check yesterday was 3 percent

Thanks, is that with WiFi data Bluetooth GPS etc off? How many hours standby did you lose 3% on?
The amazing battery life has a lot to do with the display too. It is a hugely more efficient panel.
Samsung gave the Galaxy S23 series a new energy-efficient AMOLED display
Samsung confirmed that it has fitted the Galaxy S23 line with a new type of AMOLED display that saves on power.

All on. Wifi. Data. Location. Bluetooth. Performance mode.
I'm so happy with this battery performance and am afraid to update OS when it comes out...Given the great track record of Samsung breaking things that don't need fixing, there's a high probability that the battery life will go for a toss
Had my s23 ultra since 7 Feb and consistently get just under 10 hours of SOT (most of my day is indoors on WiFi, with a 2 or 3 hours walk most afternoons in 4g)
I am running pretty.much on default settings for screen and battery - I just use my phone normally and forget about battery optimisation settings
This is the best battery.life EVER on a Samsung!
After 2 weeks with the 23u and my standard use of it i have from 85% to 30% (i never go below 30%) 4h SoT

I think it is ok. I use performance mode, all location, Bluetooth with watch, some 5G, some WiFi etc.
I mostly read on phone, scrolling...

Have you done anything specific in battery settings? Any debloating? Is this with wqhd + 120hz? Standard mode or lite mode? What's your battery settings ?

Yes I did debloat, light batter profile and battery saving (it's more than powerfu enough).
Plus I have disabled all the nearby services for smarthings find the phone offline wifi quick share etc.
I don't like having the phone always sending radio signals around for no reason

Can you give a brief list of what you debloated?
Also, android system intelligence service, is that even a necessary app? Would cause any issues if I disabled/deleted it?

Honestly I didn't track the changes, but I followed this guide
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...

I wasn't even too much aggressive with debloating, maybe I'll go for a second round
