Galaxy s4 HUGE battery drain

[Platypus]

Try this one: cat /proc/wakelocks > /sdcard/wakelocks.txt

Make sure you do this after you notice significant drain.

Well, something it's wrong.. either the cmd or anything else with my phone.

I can't really see the full output there from the screenshot, but it works again on this stock jf firmware on my US s4...

Can you just try running this?

cat /proc/wakelocks

Does that return data to your terminal or does it say no such file or directory still?

ok, well for some reason samsung decided to lock down the i9500 build and not the US variants, which is literally the opposite of how they usually operate. If you're not able to get that information, you'll have to rely on the shitty battery stats menu to tell you whats going on, which is useless and won't show you whats actually happening.

at this point just do a factory reset and load back your apps one by one, hopefully you find the culprit.
