Why you don’t need a task killer app with Android.
Posted Posted by Cody Banks on 25th May 2010 Comments 5 comments
A lot of people have asked us what the best app is for killing tasks? Well, the answer is none of them. Sure there are some nice apps out there for killing tasks, but the fact is you just don’t need one with Android. In fact, most developers
won’t even look at your logcat file if they see you running a task killer app on your Android-based phone.
To clear things up about this, Google’s Android developers blog has finally put this debate to rest about why a task killer is unnecessary, as well as why there are certain services that run in the background all the time, I’m sure at one time or another you’ve seen them and asked yourself “Why do those services keep starting after I kill them?”. Below you can read about when applications stop.......

I've found no matter how many times it's said, someone will have an anecdote about how their phone became amazingly fast or they doubled battery life using one of these apps. People who want to use them will continue to do so. Don't trouble yourself.

It's nice to have one to kill the odd app that is messing up, but other than that I don't use one.

the reason people say this is because it's actually true.
that's just the truth, maybe you should try using one and notice the difference.
I uninstalled mine for the first time yesterday to test the theory and today, my battery lasted a grand total of 4.5 hours. that's a whole 3 hours less than before.
and at the end of the day, when it's laggy and then use the TK, it really does clear things up.
still wish there was a way to make the battery last longer, it really does suck

You can do this from android... no need for an app.

I'd say if you're only getting between 4.5 and 7.5 hours battery life, I'd say you've probably got a rogue app installed anyway.

I agree, taskkillers aren't battery savers they are drainers...
Have had my desire for a couple of days now (comming from a htc hero) and since I removed my taskmanager my desire has juice for about 1,5 days.
With taskpanel I hardly reached 24 hours... And I haven't noticed the device becoming slower...
I don't miss it and if I don't get any strange apps I won't ever install a taskmanager again...

well there are some apps which don't work properly.
Take the xda android app as example. it would sometimes just freeze, and there was no way to restart the app, no option for force close was provided by Android OS either.
In this case Android isn't doing anything, so you have to kill the process manually using
1. the default android feature
2. using a task killer.
I like the quick access to the advanced task killer over the notification area, therefore i use it.
People can tell me whole day long how ingenius Android is, and that it will do everything automatically. But i made very different experiences with some 3rd party apps, which needed some killing every now and then. The xda app is only ONE example of many.

The thing is I HAVE used them. Advanced Task Killer was the first app I installed on receiving my Desire...the phone became glitchy and buggy and laggy and it was horrible. I uninstalled ATK and all that stopped. It now NEVER slows down, and I'm getting well over 8hrs of use a day.
I suspect you have a buggy app, and THAT is what you need to find.
We need to stop giving bad app developers a feww ride by ignoring their bad code and just killing the process. Uninstall their app, give it a bad review and insist on using a rival app.

You can force close an app from Android. Menu > Settings > Applications > Manage Applications > Locate the app > open it and force stop.
Create a shortcut to manage applications short cut on your home screen if you like, then you'll only need to do this:
Open Manage Applictions short cut > Locate the app > open it and force stop. - This is just as simple as using a task manager shortcut.

actually using the notification drawer is more comfortable for me. But this is just personal preference.

Yes-They might be useful to kill the occasional rogue app. but apart from that they are pretty pointless. Android does a good job of killing tasks itself.
Despite all the evidence to the contrary people many will continue to use them and use them indiscriminately. Still if they want generally poorer performance and reduced battery life surely that is their choice.

How does that work. the notification draw is pretty much blank most of the time save for new message/downloads etc ?

has anyone actually tried to load up so many apps, so there's almost no memory left, so android kills other apps by himself? It's all excellent in theory, but never witnessed it in real life.

guys I had advanced task manager installed in my phone and my phone was laggy, and my battery was always down to 40-50% at the end of the day, but yesterday on someone's advice I removed ATM, and instantly i noticed the difference, there was no lag in the menus and everything was smooth, and today my battery was an astonishing 85 % remaining when i came back home, and I intentionaly used my phone more than usual. so at least one thing is sure that I will not be using any task manager.

with advanced task manager you can see a small icon at the notification area (at all times). When pulling down the drawer you'll see an entry which says "advanced task manager".
just touch it and a list with current running apps will show up.

there are way too many variables in this equation, as to just claim that ATM is responsible for hogging 30-40% battery power per day.
Of course it will have some kind of impact, just like other apps too. But i don't think that it will have a much bigger impact.

no, I dont think there are any variables involved in my case except ATM, I never use internet on mine phone during the day coz i always have internet access on my laptop, instead today I used wifi intentionaly just for testing battery and played asphalt which I normaly dont play during the work hours,

Here's a video from the Developer site that explains very well how Android manages Apps:
http://developer.android.com/videos/index.html#v=fL6gSd4ugSI
And if I really need to kill something (very rare!) then I use Task Tray Beta:
http://www.appbrain.com/app/com.stonedonkey.tasktray or find it in the Market.
This app is also great for seeing what 's actually running and what 's not anymore. And for switching to some App that you know is running, but in the default Android task switcher you can see only 6 apps.... and this will show all.

I tried out a few task killer but all they did was stop my alarm going off in the morning! I'm sure that's something I could have changed though.
I find the best way to keep my desire running nice and quick is to give it a reboot every morning on my way to work. Only takes a couple of minutes....give it a try...

[BATTERY]Tips for better battery life

Here i would be presenting a thread in which i will be talking about how to get the most of your battery on our beautiful phones. It is a fact that at this moment of time battery is not that great on the HOX. But hopefully with the tips that i will present here, shall help people get the max out of their battery till we have some custom kernels drop our way. So without further or do i present a few things that you can do to get the most out of your battery.​​​​
Tips for better battery life​
1) Touch screen sounds and lock screen sounds untick them from Settings-Sound. That causes the audio_out1 wakelock and unfortunately it is here as well on the HOX and drains battery like hell. So untick those so you do not get that massive wakelock
2) If you are using stock rom and have not rooted yet you can use this option to disable bloatware. Go into settings-apps and go into all. There you can select the applications you want to disable. What that does it will not unistall them but freeze them like TB does for rooted phones. It will remove them from the background and from your app screen to. Pretty nice feature if you ask me. Mainly disable your carrier apps and the google ones as well like Play Books, Play Movies and Play Music if you do not use them. Just a small addition to be added thanks to (pnnorth)- If there have been any play store updates to the app, you will need to uninstall the update before it will show the option to disable the app (eg facebook)
3) If you are using Titanium Backup(i always recommend to get the Pro version) you can uninstall those apps or freeze them if you like. For me i personally would uninstall them as they do not have any use for me.
4) If you are at home and you want to browse the net on your phone always make sure you use Wifi. It is a no brainer that wifi drains less battery than 3G. So always have your mobile data in settings as off and just use wifi. When you are out and about though make sure you have wifi off and use your mobile data on your phone instead. Because if you have wifi on as well it will try and scan for the available networks it can pick up and that causes drainage on your battery. Have that off when you go out.
5) Regarding brightness. Make sure you either have it on low settings or auto. It is a fact that if you have max brightness for your display that is a battery killer as well. Settings-display-brightness and just adjust from there.
6) Regarding task killer apps or battery saving apps like Juice Defender i recommend to stay away from those. Those apps consume more battery than they are suppose to be saving. Regarding task killers it is NOT recommended to kill apps because Android does that for you anyway. Just make sure you the application that you use, you always use the back button to exit the app or just go into multitask and swipe it away.
7) If you are rooted make sure you fully charge your phone and then in recovery or from Leedroid tweaks if you are using that make sure you wipe battery stats. That always helps as well.
8) Regarding sync your accounts. Now i have mine on autosync. From reading around having to sync your email account and facebook and twitter and whatever account you have syncing that drains battery. Now you can do two things. One either set the option to have those on manual sync or if you do not use facebook then uninstall it. But to be honest i have everything on autosync and still get good battery so it is down to user preference really. But for those interested go into settings-accounts and sync and adjust to your choosing.
9) Switch to gsm/2g only instead of wcdma/3g in settings >mobile network >Network Mode. Specially if you're not planning to use any 3g internet/mms features. (thanks to Gdelrosario)
10) Try to avoid ad supported apps. A research showed that in apps where there is adds, 70% of the power use comes from downloading and managing those adds to your screen. 30sec use of an app that uses adds, might drain your fully charged battery 0.35%-0.70%. Research link found here (thanks to Tont0)
11) Settings > Developer options > Windows animation scale > "Animation is OFF".
12) Mentioned this above but will re-post here again with a bit more detail. (thanks to AndroidGX) If you have multiple mail accounts, turn off auto-sync feature to refresh them manually. Settings > Accounts & sync > Auto-sync : [UNTICK]
Note: this will works also for any app like Facebook, Twitter, Beautiful Widget, etc..
13) Disabling the options for louder ringtone when inside a pocket and stopping the ringtone when picking up the device might also help. (thanks to Hardstuffmuc)
14) Settings > Wi-Fi > Advanced > Keep Wi-Fi on during sleep : "Only when plugged in". That way wifi will not be on all the time and that means saving bit of juice in the process
LINKS:​
*Link to the thread for BetterBatteryStats is below. Please install that app as it will help you to identify what app consumes your battery when you have screen off.
http://forum.xda-developers.com/showthread.php?t=1179809
*Another great thread to have a look at is the Rom Cleaner by Patrics83. What it does it basically gives you this option : Will remove as much as possible without breaking HTC Sense Launcher and Widgets! This is the best way to come close to a no-sense ROM and still use HTC Sense!
http://forum.xda-developers.com/showthread.php?t=1589949
That is it for now. I will be updating this thread when i come across more battery saving tips. For now if anyone has anymore please post them and i will add them to the OP and give a thanks to you by adding your name next to the tip.

Was going to compile a list of apps that are safe to disable (for non-rooted users) and what to freeze uninstall (for rooted users). But since there is Rom Cleaner thread by Patrics83 as i have stated above you are probably best to go to his thread here where you can use his script and follow the guide on OP. This is script is for rooted users.
There also you can find a list of applications that is safe to disable for all those who are non rooted. Settings-apps and then go into all apps. As pointed out in first post tip 2 first if the application you are trying to disable has been updated first uninstall the updates and then disable the app
That is it for now more will follow

6) Regarding task killer apps or battery saving apps like Juice Defender i recommend to stay away from those. Those apps consume more battery than they are suppose to be saving. Regarding task killers it is NOT recommended to kill apps because Android does that for you anyway. Just make sure you the application that you use, you always use the back button to exit the app or just go into multitask and swipe it away.

This is not a task killer. Also the apps are not aktive in backgraound, they are hibernatet. If you want to kill a task go to task manager.

Juice Defender=Battery Saving App = Not so much of a battery saving app
And Maps, and even facebook are active in the background my friend. by disabling them you are kinda like freezing them anyway. And yes if you read above if you want to kill a task or terminate an app i did mention that you can do that through Task manager. Or even by going into multi tasking app and swiping the one that you do not use anymore exits the app my friend
Trust me i done my research before posting this thread. But i am also open to correcting something if i am wrong.

Just a small addition to point 2) - If there have been any play store updates to the app, you will need to uninstall the update before it will show the option to disable the app (eg facebook)

I already made another thread posting this one, but as I noticed there is one where to gather some common tips, I might as well add it here.
Try to avoid ad supported apps. A research showed that in apps where there is adds, 70% of the power use comes from downloading and managing those adds to your screen. 30sec use of an app that uses adds, might drain your fully charged battery 0.35%-0.70%.
Here is the link for the research http://www.androidauthority.com/ad-suported-android-apps-battery-drain-65716/

Very good thread. I tend to do most of what is mentioned anyway. As soon I got the phone I was busy tweaking the settings so that I could get the maximum power out of the battery. I'm not considered a heavy user anyway so it typically lasts 2-3 days.

you can also add to switch to gsm/2g only instead of wcdma/3g in settings >mobile network >Network Mode
specially if you're not planning to use any 3g internet/mms features

Cheers guys...Any tips that we can get i can add them all to the OP so that way we can have one thread which has everything. That way no need for clutter of threads regarding on how to improve battery life people can come here and read and discuss. Thank you guys i really appreciate your help

Added the new tips to the OP. Thanks

Qn: Are all battery saving apps not actually saving battery then? (E.g. Juice Defender)

wiping battery stats is done when reaching 100% charge and holds nothing but the useage of apps and does nothing to calibrate or improve battery life.
heres a quote to back this up.
Deleting this file will basically wipe your battery usage reports, which is done anyways automatically when the phone is fully charged (hence you'll see a clear list when you reach a full charge). "Deleting it is not going to do anything to make your more device more fantastic and wonderful".

i will be honest with you. When i had my galaxy s2 and i had juice defender on that drained more battery than it was suppose to be saving. I could find you posts from users and kernel developers that i know from the s2 forums that advice against it. It is down to you to try and test but from my own testings i would advice against using them

True. You do have a point. but also on the other hand there has been people that saying by wiping battery stats that deletes the battery history makes everything start fresh as you mentioned above. What i am trying to get maybe it works maybe it does not. But one thing i know from my own experience by deleting those battery stats did help a bit on my battery. Hence why i posted that in the OP.

Like i said mate. In general i have not bothered with battery apps. For me they eat more battery than they are suppose to be saving.

That is easy to figure out. Most of the times it will be all the free apps in the market. If you are rooted install ADaway and that will install the hosts on your phone and will block those ads.

Use of "No background Process" - in Developer option

Hi, Please some one help me about Use of "No background Process" - in Developer option . Because i have enabled this option in My Honor 8 Pro to stop background Process. With this option enabled most of the Google services also like Chrome, Youtube are all getting stoped once i removed from app tray. when i am opening those apps are running normally no other issue.
My doubts are whether this option is useful or not, because i am reading some stuffs online it is saying it will drain the Battery lot. if i havn't enabled this option most of the apps are running in background even i removed those apps from app tray.
Please some one help me with clear idea, whether i can close the app try or can i continue by enabling this "No background process". Because i am not heavy user, i am just a lite user between one hour i will open whatapp thats it, once in a day i will use Youtube for 30 minutes.

First and foremost thing in Android is - Free ram is wastage
When you select the no background process option, the apps will be removed from background when you clear them from the recents screen. It means all their processess will be terminated.
So, everytime you open an app, all its processess need to be restarted from the start which will in turn use more battery overtime.
Android has now evolved upto the level where it can easily manage the background process.
So, you need not to worry about battery draining because of apps running in background.
If you use just 2 or 3 apps in a day, you can choose the option to keep 3 or 4 background processes.

Thanks for the reply, Now i make it to maximum-3 Process in background. Let me see whether it is helping me to improve the battery life.
One more thing, if i set to "No background Process" then even though if i kept the apps in try (not closing just minimizing) , it is automatically stopped when i am checking in task manager, but those apps are in tray( looks like in RAM). In this method also will Drain the battery? Please reply

As mentioned above, opening your apps from start will use up more battery because it has to load everything to run the app (generally libraries, images, and various resources).
Keeping an app open in background will result in a more lasting battery. If they are in the tray, your system will not shut them down as you are supposed to be using them (that's what we call multi-tasking).
Although, if you "close" an app, it will force the process to stop. By doing this, every time you quit an app by clearing it in the tray, the system will free the temporary data and discharge the pre-loaded resources.
As K.khiladi said, you'll save up more battery by letting the default option (Standard limit). Hope that helps.

That's the reason the option is only accessable through Dev Options.

Galaxy S10+ Battery Optimisation guide

After my truth revealing updates and posts are deleted by the team with the excuse of them being "offensive" when there's clearly no offence, I decided you don't deserve any of this, your right to generate traffic using my content is forfeit.
The guide will not be updated:
I'm not going to update this guide or answer any question anymore.
Mod Edit: Content in violation of Forum Rules (disrespectful, insulting, rude) with no content related to this guide, removed

Corv0 said:
Many users have asked more details on how I achieved my battery life results, this guide will cover some basic settings and behaviors that are proven or supposed to reduce energy consumption, no root involved.
Power results to expect:
7-9h SoT: Mainly 4G, mid to max brightness, navigation applications and outdoors utilities.
9-11h SoT: Your average work day, 50% max brightness and 4G, 50% half brightness or less on WiFi, mainly video playing, communication and web browsing applications.
11-14h SoT: Same as above but with lowered screen brightness and no 4G.
Gaming applications automatically forfeit any battery report due to too many variables. I can’t include them, but your gaming time will certainly last longer if you follow everything.
According to what has been seen on forums, Snapdragon versions seem to perform considerably worse than Exynos ones regarding power consumption and they should be expected to not last as much, I’m still waiting to see a side by side battery test between the two, please mention your model when posting screenshots.
Initial Setup
Just a few options here:
Avoid restoring backups from older/previous devices, Google’s app data restoring system has been known to permanently influence Play Services’ drain.
Smart Switch is also bugged, do not use it, everyone saw better results by skipping it.
Set up as new and import only what you need.
Theme
Night Theme
Black/Night themes will reduce power consumption without doubt while helping your AMOLED maintain quality for the future, your Quickpanel has a simple shortcut to enable Night mode system-wide and on supported Samsung applications, keep it on all the time if possible.
Quickpanel
Your Quickpanel is not actually black in Night mode (85% black), it also forces your device to drop frames every time it is summoned by blurring the background, a very expensive and unnecessary effect.
Download Good Lock from the Galaxy store
Open QuickStar, set BG Color to black (make sure to run the bar to the darkest end) and disable Blur effect.
Launcher
As smooth and elegant as OneUI Home can look, it is stupidly heavy on the GPU, especially when launching the app drawer (unnecessary blur effect again), you can see Nova and OneUI Home compared:
Nova: No frames dropped
OneUI: Dropping frames EVERY single time the drawer is summoned, keeps dropping several scrolls later too.
You can make Nova look exactly the same as stock OneUI while having more features and better performance.
Background wallpapers
Darker wallpapers will help, but overall no big deal.
Animated wallpapers are expensive, you’re not going to stare at them, keep your wallpapers static and your animations in the gallery.
Connections
More connection settings: Disable Nearby device scanning, it’s mostly used to push ads whenever you’re around malls and shops.
Private DNS: Set your DNS to 1dot1dot1dot.cloudflare-dns.com, Cloudflare’s DNS will greatly improve your browsing speeds. This setting will also make it harder for Google to track you around the web, you will be blacklisted from Google Opinion Rewards by keeping it on, if you do not use Google Opinion Rewards then you have absolutely nothing to worry about.
Location services
Biometrics and Security, Location, disable everything under Improve accuracy, you don’t need this on this phone, nobody does, modern GPS systems are already accurate enough indoors to not justify having to scan for Wifi SSIDs or Bluetooth even when they're off.
Audio
Dolby Atmos requires some additional processing to handle the extra channels, if you do not hear any quality difference, keep it off.
Display
FHD+ (2280 x 1080) and WQHD+ (3040 x 1440) will look exactly the same to the untrained eye.
WQHD+ will to make your GPU worry about 23% more pixels, it will result in:
-30min off your average SoT day
-25% less autonomy in 3D games
I personally couldn’t go back to 1080p after upgrading all my displays. All my SoT screenshots have been taken on 1440p settings.
Apps
Most apps can be disabled from Settings, Apps, for apps that can’t be disabled that way, I recommend using this guide if you are unfamiliar with Adhell.
After disabling everything related to Facebook (use alternative apps if you really need it), do not keep duplicate active services that do the same kind of tasks;
If you are using Gboard as keyboard, disable Samsung Keyboard and Keyboard Neural beta
If you are not using OneUI Home then disable OneIU Home and Bixby Home.
You can safely disable Bixby itself if you prefer Google Assistant or no assistant at all.
You can apply the same principle to all the system apps you think aren’t useful to you, this will greatly reduce RAM usage and CPU wakelocks/alarms.
Battery Monitors
They’re not free to use, they drain energy by logging, everything does.
Unless you’re specifically checking for rogue apps attacking your battery, get rid of Accubattery or similar apps.
Keyboard
The two best keyboards I know are Gboard and Samsung keyboard, I do not like and cannot recommend any other.
Your keyboard should also be black at all times, that will result in at least 30% less power waste when typing, Gboard and Samsung Keyboard have their own themes for that.
Disable anything that makes your buttons clicking sounds or vibrations, it’s unnecessary, energy expensive and has been demonstrated to not improve your typing performance in any way.
Device Care
Good utility, but you shouldn’t run it manually and you shouldn’t kill apps with it, instead:
Enable Auto optimisation, set it some-when during your sleep.
Enable Auto restart, no Operating System is immune to bugs manifesting by staying on for too long, make your device restart itself at least every 3 days, when you sleep, and at least 10 minutes after auto optimisation is supposed to run.
Disable Security, Samsung is getting paid to put this McAfee crap in their firmware, in the EU it will be disabled by default since it is also a tracker not initially included in any other contract from Samsung.
If you accidentally enable it, go to Apps, look for Device Security, and wipe data, that will disable it.
Android does not need an Antivirus, you will not get malware unless you install modified apps with unofficial signatures (the Play Store still has malware too, stay away from shady apps), if you often try third party apps from the outside, make sure your apks are clean by uploading them to www.virustotal.com.
If you suspect your phone has been infected and you can’t identify the package, install a better Antivirus software such as Bitdefender or Avira, but I don’t recommend keeping them installed unless you are playing with high risk applications all the time.
Sleeping apps
Sleeping apps puts unused (not in your multitasker) apps to sleep, alike pressing X on a desktop Operating System.
Since most apps are badly optimised and using Android’s great RAM management to keep them alive only results in more wakelocks and drain, Samsung deserves a lot of respect for letting us do this without third party apps such as Brevent or Greenify.
You need to have Outlook installed on your phone to follow those annoying work e-mails, but you’re tired of notifications? Put it to sleep.
Put every app to sleep unless:
You need notifications from it
You use it often
Animations
Animations are expensive and make your system appear slower, reducing them will help by making your GPU draw less frames.
They can be sped up or disabled from Developer options, I recommend .5x for a good balance, to enable developer options:
Settings, about phone, software information, repeatedly tap on Build number until you magically become a developer.
Additional animations can be removed by enabling Reduce animations in Advanced features and Remove Animations in Accessibility, Visibility enhancements.
Ad-blocking
If you are using Adhell, that’s your best adblocker for Knox devices.
https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts is the best collection of hosts, make sure your Adhell is whitelisting Analytics domains, you will notice these domains being spammed under “Domains blocked in past 24 hours”, Android will keep trying to reach those domains until they are whitelisted.
If you don’t want to use Adhell for whatever reason, Blokada is an excellent VPN-based adblocker that is way less invasive and does not seem to impact battery, use it with the recommended hosts and keep it on at all times, enable always on if you notice it getting killed often.

When trying to put a private dns I added it and lose data and Wi-Fi it spazes out if I turn the private dns off it's fine. I am from Australia would that be any? 1dot1dot1dot.cloudflare-dns.com is it this or 1.1.1..cloudflare-dns.com

What is your opinion about "adaptive power saving" in performance options?
Should we turn it on?

Very helpful thank you

It should be on, I forgot to include it, thank you.
@dominicstg2 It might not work well in every region, in that case you can just skip it.
A great alternative to facebook is Face Slim

some great tips there thank you
so if you are struggling battery life wise should you go from QHD to FHD or does it make no real difference? and would you say having a blue wallpaper would drain a lot more than a black wallpaper?

FHD will definitely help but I find vision quality to be a higher priority over half an hour or more of battery per full cycle, it's totally up to you.
Blue wallpapers will in theory drain more than any other colour, this Dynamic AMOLED's blue subpixel is much larger than the others, but you won't feel the difference unless you stay still on your home page for long periods of time.

Also one small correction if I may. The correct DNS should be 1dot1dot1dot1.cloudflare-dns.com
(you forgot the last 1 at the end).

 @dominicstg2 try the correct one.

are the "dot" in the dns name to be letters or a . ? the latter didn't work for me.
By the way do you happen to know why the sync feature keeps re enabling itself ?

Sync will go back on every time you accept to sync in a Google app.

I'm not sure about the "sync in a google app" as even going thru parameters (without opening any app, above all a google one), it keeps re enabling itself. I suspect that the S10 os is buggy (this android version or samsung implementation ??) or embedded with hidden (unreachable) parameters.

I tried every single one of Google's apps and I couldn't replicate your bug, it stays off.
Did you restore through Smart switch or Google backup?

@Corv0 I had a bug where I could not download anything at all wiped Google play etc ended up doing a factory reset and don't you steps again and my battery is great thi k stand byvis fixed

Just one thing to add. That is really great and comprehensive guide. I actually disabled few apps and services. Be aware though, if you disable One UI launcher and are using navigation gestures, you will lose recents and back gesture.

What is your processor?

Corv0 said:
Biometrics and Security, Location, disable everything under Improve accuracy, you don’t need this on this phone, nobody does, modern GPS systems are already accurate enough indoors to not justify having to scan for Wifi SSIDs or Bluetooth even when they're off.

So, it's ok to let the Location "ON" and just disable everything under "improve accuracy"? The battery draining isn't significant for location "on" or "off"?
I remember in Oreo we had the opportunity to set it on battery saving.

How do I get good battery life

Hi guys,
So around 1 month ago now, I got myself hands on a Note10+ (N975F)
I have been noticing screen off time drain, it is around 1.8% for me. I have tried using greenify, optimizing the settings, battery saving mode etc.
It hasn't really been working for me. Screen off time is really important for me, even more than screen on time.
So i wanted to know, how could I maximize the battery life of my Note10+? Is there like a custom rom you could recommend, like Lineage or dr ketan?
Knox is already tripped bcz of the previous owner, so that is no problem. Or a other custom rom or just with rooting something.
If you know anything, I would appreciate it if you could tell me,
Kind regards,
Crewz

First, you can select apps that you dont require to be always running, to be dormant, look for this option in settings, also you can install galaxy labs, there is a similar option there also, I disabled several apps via CCSWE, that have the undesirable behavior of being always running and accesing internet, such as facebook, chrome, youtube, operator apps, etc, also, with CCSWE you can deprive apps of certain undesired services that eat batt, this a process that takes some time, as you use the device, you can obseve and decide what to disable, to uninstall, or control via ccswe, I have my note 10+ since Sept 6 2019 and the battery lasts thru the whole day, I get some 7 hrs SOT on normal std use, when I play intensive games,, that is another diferent thing

Hey thank you for taking the time to help me. I have tried what you said, I went into settings and I went through my apps and selected those that don't need to run in the background. I also downloaded CCSWE from the playstore, i saw like 500 applications, but only disable or clear data from the application.
Are there any other device settings you recommend changing?
Thanks for your time.

Decide if you want to root it, if so you'll have many more options and tools to work with.
Otherwise get PD MDM to block apks from running at boot and disable them.
Use Samsung Device Manager and set to Optimized in main window. Toggle on fast charging but don't enable any other off the top 3 dot menu. You can then disable that app too. 3rd party power management apps including Samsung's can screw it up. Cloud apps, Goggle Backup Transport/Backup Framework are big offenders on my stock 10+
Disable Google, Samsung and any carrier feedback.
To hell with Bixby except Bixby Vision/Vision Framework which are needed by the cam for full functionality.
Play with it.

Hey thanks for your reply. I would want to root it, I am not sure how. I have owned a oneplus 7 pro where it was much easier to do.
If I would root, what other options and tools could I use?
Also, I did those settings things from the battery, thank you.
Not sure what you mean with Google / Samsung feedback.
For bixby I disabled almost everything except vision and routines.

Don't disable Bixby Framework either.
The feedback options are buried in settings, you'll run into them.
I'm not rooted so I don't spend much time looking at what I could do. You do have real time cpu/power usage capabilities with it for weeding out the hogs... for one thing.

Hmmm, can't really find those feedback options. I will enable the framework again.
I guess I will root when it is really needed to. First let's see what I can do without.

In the Goggle and Samsung account settings.
If it's a carrier phone one of the advanced network settings. Carrier phone; disable remote support, updates (unless you want an update), and all their software.
Keep Samsung account and apps related to Galaxy Store/Themes as you want to be able to download themes, icon packs and apps from there.
Excellent free icon packs... and the Good Lock family of apps.

Should be about 1% when sleeping with AOD on.
Keep the AOD to a bare minimum though ie just a clock no images.

Galaxy labs, Battery Tracker is useful.
See if Google Backup Transport or Framework are the culprits. If already package blocked clear their data and the data on Goggle Play Services ie gms.
It can be hard to ferret out as many apks simply are thrown together under Android Services.
Worse some Google apps falsely show under Transport etc even when its blocked. That why you clear the data of gms.
Use the factory load of Samsung Device Manager to globally clean caches. Reboots seldom help.
Turn off location, bt and wifi if not using.
Do not let Playstore run or Samsung updates unless your using them.
When running clean its ide current with screen on is typically in the 100-200 ma range. A few lower and higher. If you're getting a lot of spikes 400 ma and above at idle something is using a lot of the cpu resources...

So I installed Galaxy Labs and Battery Tracker.
I noticed that Google Foto's was on top with 7.1%.
Followed was whatsapp with 6.3%
And google play service was 3.78%
I haven't seen Google Backup Transport in the list.
Would there be like a way to turn off location automaticly when I am not using it, for example that it would only turn on for google maps or something?
Thanks for your time!

If you leave locations on it's a whore to a lot of apps including Google. Looks like you found your prime suspects.
Lol, WhatsApp never runs here same with FB.
