During the Note 3 days, custom kernels play a major role to SOT. I install greenify and amplify on my Note8, the best I could get is nearly 4 hours SOT. Some can even get up to 6 - 7 hours without root. I guess it all depends on how you use it. Tried phant0m kernel, didn't notice any difference. Currently using madmax kernel. Other kernels are just as good I think. It's just that some of the devs have moved to other devices.

Ya, it depends on the usage of the users.
I don't play games at all.

May I know if your Note 8's desktop mode still working after installing the custom rom and kernel?

Anyone received Sept update?

I just noticed mine is still under August Update but i saw "Super slow-mo" under my camera app there.

I thought it is a Sept update?

Are u sure is super slow mo instead of slow motion?

Ahhhhh... my bad XD

It's "slow motion" now 

for battery replacement, we hust told them its draining badly

will they do some test to confirm our claim?or straight proceed with battery replacement?

btw, its eligible to all right with warranty still valid?
