Hacking Question underclock to save battery

[butawsky]

what do you guys think if i underclock the gpu and cpu by 100mhz or maybe 200mhz if possible and still playable,can i achieve +30mins-1hour battery life doing this? and my firmware is 12.1.0 i dont know if sysclk supported my current fw... thankyou

its too little to achieve +30mins/1 hour of battery life. But generally, yes, underclocking should give you some more additional battery life, especially with not demanding titles like 2d pixel platformers/roguelikes, cause whit those you can underclock a lot.

I wonder why NX can't underclock itself. Or pixeleted indie developers won't be allowed to underclock their titles.

The difference in battery life is still gonna be small. Cause even if you don't underclock while playing some pixel game, it will still use only a fraction of your cpu/gpu power. i mean the load will be very low, like 15-20%.But if you underclock, the load will be bigger percentage wise, but the actual frequencies the game uses will stay the same. i might be wrong here, but the only scenario underclocking will give you significantly more battery life only if lets say the game uses 90-100% gpu at stock clocks to maintain stable 30fps and then you underclock gpu by 20-25%, the game becomes 25fps with 90-100% load but you lowered the actual maximum freq at heavy load which will def result in more battery life (less power consumption). So, in other words underclocking to save battery life is only useful if you underclock to a degree when you sacrifice game's performance.

Oh I see, so it's not just about mhzs, but about load as well.
