Lower values will choose A57's faster so smoother exprience.
I am using values on ScreenShot and getting 8H SOT

Who explains me the values in sinapse hmp tab?

If the A57's are less battery efficient, I'm curious to know this setting helps you so much.

I just started fresh with my current ROM as I found that even with an extreme amount of tweaking, I'd get 4-5h SOT at best - exposed seems to have played a part in the poor battery life, but even now, I'm not getting more that 5h.

I was hoping that UV would he l help, but it's nothing noticeable. [emoji27]

I am using SimpleLite Rom (it is a gift for N910C Models)
No Xposed
On 8H SOT using 2 hours on 3G, and 6 Hours on WiFi this will reduce consumption
No overclock for A53, underclock to 1700MHz for A57 cluster
No gaming, Less apps less problem
Facebook app is battery drainer so using face over Chrome
SoC is ASV 8 and making UV on the limits (taking time to get stable values)

Video added for my settings.
This is all I can advise, nothing special

lowest i got is 100mv on all freqeuncy including A53 and A57 .. ASV6 .. havent got a reboot but feel close to getting one if i lower it further..

My chip is ASV5 and I managed 150mv undervolt at the highest speeds on the A57s (1287.5mv to 1137.5mv @ 1900MHz) and 137.5mv at the lower speeds. A53s managed 100-112.5mv and the GPU 75-87.5mv.

You have to remember that for lighter usage like web browsing the main power user is the screen, not the SoC so undervolting and kernel changes only have a minimal effect on battery life. Two users getting vastly different SoT will be because they are using different brightness levels (one could be in a brighter environment).

I can get on track for 11 hours SoT at home where the brightness is lower, but only 4-5 at work where my auto brightness is almost always at maximum.

Still having problems with GPU on 1.3b and 1.4. 1.3 is the fastest version for me. Everything works fine except that charging is slower than the latest versions.

My asv is 4 i run around -50 uv on everything including gpu had 1 freeze but i accidently turned of wifi so that was why but other than that stable fast and good battery life

    ** THIS CAN BRICK YOUR DEVICE **
    ** ONLY FOR SM-N910C/H MARSHMALLOW**
    IF YOU NEVER FLASH AND SET A KERNEL BE AWARE
    IF YOU ARE NOT HAPPY WITH THIS KERNEL FLASH OTHER CUSTOM KERNELS
    (GoogyMaxN4 or Wanam or Ultimate)

    I asked for permission to announce this kernel and All credits goes to @halaszk88

    DONATE to halaszk88

    Kernel V1.1 Update:

    • wireless: dhd: Enable standby ARP and multicast packet filters
    • security: SELinux: revert Samsung hard enforcing
    • cpufreq: Remember last policy min/max on cluster restart
    • HMP: Added HMP_LITTLE_PACKING control from sysfs
    • HMP: sched: Clean up hmp_up_threshold checks
    • HMP: fix out-of-range CPU possible
    • HMP: Do not fork-boost tasks coming from PIDs <= 2
    • HMP: Make idle balance behaviour normal when HMP: HMP_LITTLE_PACKING is disabled
    • ARM: Mali-T760: disabled min/max lock sysfs
    • Various sched/mm/writeback/workqueue fixes
    • gpio: sysfs: fix memory leak in gpiod_export_link
    • gpio: sysfs: fix memory leak in gpiod_sysfs_set_active_low
    • ARM: DMA: ensure that old section mappings are flushed from the TLB
    • cpufreq: interactive: merge interactive governor from new G920F source
    • input_booster: ported from SM-G920F
    • cypress-touchkey: Added input-booster event (from S6)
    • misc: Input booster: Allow configurable levels
    • Exynos-Thermal: Smoothen throttling levels
    • CPUFREQ: EGL: increase booting freq to 1.7GHz
    • ARM: enable UNALIGNED_ACCESS

    Synapse:

    • Added HMP packing mode control for Advanced TAB ( Auto mode will be able to use automatic when you are in POWER_SAVE_MOD in TW ROM, if disabled POWER_SAVE_MOD hmp_little_packing auto disabled so kernel use normal packing (more performance)

    Kernel V1.3 Update:

    Kernel:

    • Merged N910CXXU1BNL8 sourcecode from OSRC release.
    • Drivers: battery: fully reverted stupid fast_charging driver and make Universal5433 Max77843 charge control (original version thx to Andreilux)
    • Mach-Exynos: added exynos-interface for control min/max online SOC core control
    • Varios fixes for workqueue/procfs/mm/iosched/ext4/sched/irq
    • I think the WIFI touchlag has gone away
    • I made Device Tree image file generating script, now we can use a compiled dt.img from our dts source code.

    Synapse:

    • I added a new TAB to Synapse: HMP: under this TAB we can controlling HMP UP/DOWN migrating thresholds
    • New charge-control interface under Battery TAB: support and fully controlled the normal and the adaptive-fastcharging, USB, and various MHL charging current.

    Bugs - Screen Shots

    -BUGS-
    WiFi must be always ON to prevent MicroLags, TouchLag, UI Lag (Discussed on AndreiLux issue tracker)

    -My Personel Settings-
    https://youtu.be/W1if5mkhY1Q

    My personel settings are like this. UnderVolt settings will not be compitable with yours. Every SoC has it's own UV capability so try and find yours.

    -Power Advantage Calculation for My SoC -
    Exynos5433_T760.png


    As per AndreiLux's measurment:
    "A57 are about 1.87 more efficient in performance per Mhz and 4.23 times less efficient in perf/W outside of voltage droop."
