That's not exactly great, I had that in the sd820 days on a bad day.
nothing yet except like all the location/wifi/bluetooth scanning turned off. But i disabled a few apps and need to do a few more tweaks. As long as it can make it from 7 am to midnight which so far it has I am pretty good with it!
How do I whitelist those domains in the link you provided?
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.
9-12h 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.
12-15h 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:
You can make Nova look exactly the same as stock OneUI while having more features and better performance.
- Nova: No frames dropped
- OneUI: Dropping frames EVERY single time the drawer is summoned, keeps dropping several scrolls later too.
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 1dot1dot1dot1.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.
Changing your DNS in certain regions might create problems, if you notice any problem at all then skip this step.
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 (A great alternative to facebook is Face Slim), do not keep duplicate active services that do the same kind of tasks;
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.
- 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.
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:
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.
- 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.
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.
Battery
Optimised is a great battery profile, Medium power saving is also good if you do not notice any slowdown, Enabling Adaptive power saving will make your phone silently switch between the two in certain apps or during quieter times of the day, it learns from your usage, it also enables Medium power saving under 25% battery.
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:
Additional animations can be removed by enabling Reduce animations in Advanced features and Remove Animations in Accessibility, Visibility enhancements.
- Settings, about phone, software information, repeatedly tap on Build number until you magically become a developer.
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.
If you still have unexplained drain
- https://myactivity.google.com/myactivity go there and clear your account, locations included, since all time. You will not lose your Drive/Photos data or anything you uploaded voluntarily, this is to register your device as a new one to Google.
- Wipe data of Google Play Services and Google Play Store
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Android logo displays, release all three keys.
- An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
- Press the Volume down key several times to highlight wipe cache partition.
- Press Power key to select.
- Press the Volume down key to highlight yes, then press the Power key to select.
- When the wipe cache partition is complete, Reboot system now is highlighted.
- Press the Power key to restart the device. You have now cleaned your Cache partition.
Adhell, domains, whitelist and add each one, once done disable and re-enable domain rules to apply changes.
I have to add the list of 1000 links? Like one by one?
No, you only had to add the whitelisted domains, you can add the ones in the screenshot:
Ok I added them. So is that all? Do i need to do anything in adhell or will it block popups just like that?
You need to add at least one more host.
Probably Bixby Routines, which I find very good and can completely replace Tasker unless you need very specific tasks to be done, I don't need tasker for my power management.
That's great post to be honest, and I'm positive it all applies. But when I was using mate 20 pro I didn't have to apply any of it and the battery life was savagely good. Just saying...
