[Samsung Galaxy S 5 Unified Development] Cuzeg Spiked:
Edit: My average screen times did go up to 6h 30 or 7h depending on what i did. I could definitely game for an extra 30m or 1 hour also. Theoretically 10 hours is possible also but thats if my phone was idling or minimal processes for 10 hours. A great deep sleeper too, even better than before and I could have it deep sleep for hours with minimal battery loss for a day even.

Performance as expected was great on ineractuned even on low clocks like 1.4ghz on hotplug like optimised MPD or Tuned or no hotplug. I used speedmod tweaks for an overclock; i/o scheduler bfq; rq affinity either 0, 1 or 2; entropy max or untouched since i noticed nice performance gains from it even and very low impact on battery life if any, using gpu maxed all the time or idle at 200mhz because it barely made a difference in battery life but good performance, virtual memory was mostly untouched as the tweaks were already good from this kernel except from speedmod adjustments , ext4 tweaks off and fsync off since they seem to not benefit me in performance and i like to keep data safe, then usb and ac current charging at 1200mv to have slower charges but better battery life. Read ahead 128kb. I do use external 32GB SD card as storage where my files are and internal storage for all the apps but same i/o settings as my internal storage.

Used Android Runtime Optimisation magisk module which seriously improved performance on the Resurrection Remix nougat rom too for UI and games and one time i managed 8+ hours battery life. I noticed that not only changing kernel parameters improved performance+ battery life but also going into settings menu - battery, changing from either power saving, efficency, balanced, quick or performance so the OS allocates resources for either faster performance or battery savings.

Everything felt snappy and speedy even without much tweaks but with tweaks, the phone is on a whole next level of performance and it feels good as new. I do trim the filesystem ext4 data to ensure performance and nand longevity.

KT Monitor does show 1 core out or 4 used if I sleep the phone or reboot even if i enabled min 4 cores in boeffla config. It does save battery life but if i want performance, I have to constantly go into boeffla config and change min 4 cores to another profile ane bafk to min 4 cores.

AppOpsXposed, put almost every process to not boot at startup and some not keep awake and no google play was already a good part for battery life. Privacy guard to stop many apps from background running, disable location in settings and system ui to disable wifi scan in appOpsXposed if i didnt want to search wifi (beats using build prop supplicant scan interval), disable bluetooth scan by disabling location in bluetooth share when im not needing to scan any devices also. Greenify i didnt use but i can use to hibernate apps and battery is good.

Amplify was useful though, power nap and apps like Better Battery saver from xposed to disable cetain wakelocks/processes not detected by amplify (and luckypatcher/autostarts), amoled dark theme on most apps, etc. definitely great phone for battery life and performance and feels closer to my S6 performance on aosp. Mileage may vary but generally good battery. I think 4G i can have a decent battery life too. I do use blue light filter from Los menu and cf.lumen.

Highly recommend testing this version of boeffla kernel, used the latest beta22 klte.

Keep up the good work for this optimised kernel and lets see how much more juice can be pushed out of this phone. The joys of not needing a charger more than once in a day.

edit: Tested I/O scheduler changing such as sio which gave even better game performance , noop also and row too. It feels so unreal the performance but this is a pretty fast soc. Deadline is ok but i prefer noop/row. Entropy setting it didnt matter too much or rq affinity once the bottlenecks remove since i/o scheduler is massive part of performance. Gpu i use max clock speed but even low clock speed and games are still easily playable. KT monitor i checked and to make 4 cores show up, min 4 cores profile was best. this kernel is really no joke, the best ever used. GL tools apk for games to make em even easier to run. My best experience was with Noop.
