I would like to know When is Zerolemon extended battery for Samsung Galaxy S 4 Active coming out?
I think I'll follow the suggestion of having a separate battery charge and an extra battery pack.One of the other advantages of the S4Active is that it has a removable battery. What I do is, I have a second battery which I bought along with a charging pack that charges the battery independent of the phone. It was the best investment I've made in regards to phone accessories so far.
This way, I always have a second battery that I can carry around with me (in a secure little case) without sacrificing the size/aesthetic of the phone (since I can put that spare in another pocket, leave it in the car, etc) and I don't have to worry about the water proof seal. In addition to this, I'll use the MHL port a LOT less, which means I'm far less likely to damage it (or it's flimsy water-proof cover).
