Re: New French spoken review shows almost double the battery life than the S5
If that's what you mainly do, I don't think you need to worry though I would be careful about apps like facebook, google+ for auto syncs.
Also it has power saving mode, ultra power saving mode. I tested power saving mode on my S5 and it seems to extend stand by time about 40% and still more than enough power for most apps except graphic intensive ones.
I'm not a huge power user, mainly emails, calls, whatsapp, social media, web browsing so standby time works well for me.
This is the reason the Oneplus One is still an option for me
