I own a Samsung Galaxy Note II and it has a pretty impressive battery, enough to last a whole day without changing any settings on the phone. But it’s always nice to have that extra juice and disabling Samsung Push Service on my Note 2 gives enough battery life for two whole days. Disabling it on other Samsung devices also increases the battery life dramatically, I have tried this on Samsung Galaxy S3 and on Samsung Galaxy S4.
Samsung uses this service for ChatOn and other Samsung Apps so disabling the service may make such apps useless.
I also disabled ChatOn, S Voice etc

How much extra juice did you get after disabling Samsung Push Service?
