Help larger battery without a new back cover

[Android Question]

I just picked up a s5 switching from the iPhone 6. I love the phone so far but after setting a bunch of stuff with the phone off the charger it seems the battery is not up to par to the 6. Are their any larger capacity batteries that are the same dimensions as the factory battery. I'd like to keep the life proof case I just bought.

There may be some which claim to have higher capacities, but they can't be dramatically higher without being larger - for a given battery chemistry it's the volume of electrolyte that determines capacity.

Be a bit wary too: I've seen plenty of cases of slim replacement batteries which claim to be higher capacity than the originals but actually when tested are lower (this for other handsets, I don't have a S5).

Best bet might be to look in our S5 forum and see what our members recommend each other.
