my usual battery usage is around 5 days with 1hr SOT on 4.3
it used to be 3 days with 1hr SOT with 4.2.2

very little usage on my phone while most of the time i and in front of my desktop

yea, my phone dose the same thing like a nokia too.
no 3g no gaming. very minimal surfing, not even wifi.
so it perform similar i guess .

focal works nicely on n4,

but on other device it keeps fc. improvement is done to bring other device to compatibility.

so i will say it is worth to try it out.

when u keep poking a hole, the hole will become lose after some time right?
same thing with the button. something lose hence become not responsive as it was new.

if u go to their community, u will find out lots of example, heck, my sis and aunt all have unresponsive home button and i have heard before unresponsive power button as well. but then i think their number are lesser compare to number of device.
in my opinion, every device have this problem, just the number of complain only. nexus are more of a problem as it is only button to active the phone.

so true, i forgot all about that. always click the imaginary back button with iphone as i used samsung before this

i am interested also. last time bought at 89
