repost from Galaxy S7 edge forum

Hi everyone

Decided to publish a little guide on Synapse as it is big, buggy and incomprehensible.

1. Use Kernel Adiutor if u r overwhelmed. You will get very minimal difference in savings/performance etc

2. Before using Synapse make sure other apps like Kernel Adiutor are reset and not doing anything. Otherwise u will get confused and tired quickly - remember, Synapse is buggy.

3. Get Synapse app installed.

4. Open Synapse, go "Reboot->clear data and reboot"

5. Wait 3 minutes uptime in Settings->About->Phone

6. Open Synapse and click Understod and big [X} on top (cancel whatever changes were made) - it is confusing

7. Now we do actual settings. Whenever you change any numeric value - try to avoid fractions, use integers. I think that's one of the biggest issues with Synapse, it parses everything as Integer. That's my only explanation for its parsing errors I see everywhere.

8. Before leaving any screen after the change - click [OK] [V] button on top

9. A72 CPU - set minimum to 312, maximum to your taste (mine is 1976)

10. A72 Volt - MNPGS HPM Voltage Margin=50000 microVolt. Leave the rest be. There is dedicated APM chip which will decide good undervoltage for you.

11. A53 CPU - min=338, max=1586, you can overclock here, it is beneficial to have A53 at highest performance, as it consumes much less power

12. A53 Volt - Apollo HPM Voltage Margin=50000 microVolt. Leave the rest be. There is dedicated APM chip which will decide good undervoltage for you.

13. DVFS - balance. CPU threshold=80

14. CPU gov - interactive. Turbo mode=disabled. Governor itslef is heavily optimized by Samsung, so no need to try anything else for best perf/battery governor. I tried OnDemandPlus. You can read this for education http://androidmodguide.blogspot.com/p/blog-page.html

15. Hotplug - Stock. Thunderplug is buggy. Minimum CPU=1 (maximum cannot be changed!!! fsck!!!)

16. Multicore - you can bring Up Threshold higher for A57 (A72) big cores, so the load stays on A53 cores longer. Up Threshold=900. PowerMigration=disabled. HMP litile packing=disabled. Power efficient work queues=disabled.

17. Boost - key boost=battery. touch key boost=battery - or leave it default for extra responsiveness

18. GPU - power policy=coarse_demand, max=546, min=260, governor=interactive, highspeed clock=338, highspeed load=95, highspeed delay=1ms

19. GPU Volt - Mali HPM Voltage Margin=50000 microVolt. Leave the rest be. There is dedicated APM chip which will decide good undervoltage for you.

20. Thermal - lower the frequencies to be in complaince with your max GPU freq

21. BUS - Memory Bus HPM Voltage Margin=50000 microVolt. Leave the rest be. There is dedicated APM chip which will decide good undervoltage for you.

22. IO - scheduler=NOOP, read ahead=2048, IO Stats=disabled . read this if you want to play with schedulers http://androidmodguide.blogspot.com/p/io-schedulers.html

23. MEMORY - Low memory kill profile=Low, Samsung SPCM=disabled, Ulra Kernel Samepage Merging (UKSM)=enabled, scan delay=1 sec. Max CPU consumption=6%, FSync=disabled, VNSwap=Enabled, E-Swap=disabled, Laptop Mode=Enabled, Z-RAM=0, Max Compression Streams=2

24. ADVANCED - Gentle Fair Sleepers=Enabled, Randomize via space=2 (do not disable it, it is a security feature against rogue hackers)

25. DOZE - mode=Enabled, Doze Idle=Aggressive, profile=User, maximize timing for all delays, click [V] [OK], then [Apply User Parameters]

26. WAKELOCKS - some sensor settings here made my clock stop in status bar, so disable sensors sparingly. GPlayBatFix=enable, all sensor hubs=disabled, all numeric values to minimize wakelocks, lower wake time.

27. BATTERY - I suggest avoid touching anything there. You can click [Reset fuel gauge chip] at the very bottom. It will be rarely needed. Only if your battery will decide to go bad quickly. Then this recabliration will help to get more precise percentage numbers and battery life estimates.

28. LED- do not touch. LCD ALPM=disabled. Make sure your Edge screen is disabled under Settings->Display-Edge Screen

29. NETWORK - MPTCP=disabled (unless you want to aggregate Wifi and mobile network, and even then results are not guaranteed). TCP Congestion=westwood. TCP/IP Network Security=Enabled. DNS Tweaks=OpenDNS, GPS Region- choose yours, IPv6=disabled (depends on your mobile provider ISP)

30. SECURITY - chances are you won't need to do anything there. If you have KNOX - disable it by all means

31. FS - some good tools here to optimize databases and filesystems, you can try them all.

32. Cortex - disabled. Didn't work for me. You can try it :) :D

33. Crontab - enabled, tasks - chances are you will need them all. I disabled the ones which deal with filesystems and databases as I have init.d scripts for the same.

34. USB MODE - no changes

35. Backup/Restore - buggy non working functionality for me. Good luck.

36. LOGS - no change

37. REBOOT - click on "Clear Synapse Data and Reboot" if you see bad errors

38. INFO - my post should have been there :)

???

Profit!!!
