I hope it is too! Mugen makes a quality battery and you will get more life than stock, without a doubt.
Howerver, it should be noted that users of the Anker Battery 1900mah are reporting longer runtimes than my battery for a cheaper price. Please keep that in mind before purchasing. I've seen a couple users stating 24 hours of good use.
I don't own that battery so I'm just trying to give a detailed representation of my real world useage on the Mugen 1800mah. In my previous screenshots, it says the display was on for 4 hours total. I was using it quite a bit today, on various apps so I'm not sure why only XDA shows up in the usage. I messaged quite a bit too but I'm not sure what that shows up as. Does that fall under Dialer usage I wonder?
As I posted in the other thread, I'm getting about 10 hours of moderate-heavy use out of my Anker batteries. Read the consumer reviews before buying batteries.
