slim bean 4.2.1 beta 2 battery life not as good as beta 1 thou

wifi only?

Looks not bad, thinking of going back to Slimbean. 

Not much difference, for me, is still good. 
Is Slimbean 4.2.1 come with Lean 5.5.1 ? or u flash it separately ?

slim bean beta 2 is with lean kernel 5.5.1
i will test and see..now im back to lean kernel 5.5.1

I see, then nvm la, will stick to beta 1 first. Monitor the performance for few days first. 
I flashed beta 1 because I'm a little bit lazy to flash again if beta 2 got 'problem'. 
Thanks for your info !

EDITED: The performance tweak option is available after I enabled the developer options, that's make sense. 

left in the car only wo, under shade the whole week. o.o not much heat aso.

split into two. the whole cover split. i forgot to take picture. whoops. 

the mini usb i wanted to plug in the plop, go inside d. hahaha!! i din even pry it open, it was just open when i took it out. o.o
