It never was my intention to be scientific anyway...
Just saying that in MY experience, iPhone battery life is crap and it always has been. I just thought that android is even more behind when it comes to this.
Why I can say this?
Because I'm using hers for quite a while.
I opend a thread a few weeks ago, mentioning my gf phone, saying that I will try it and yes, battery is one of a few good reasons why im considering to switch. Just out of money atm...
If you're ok with your battery life thats just fine. But i am growing accustomed to 48h without thinking about charging. Never had that experience with any iphone ever.
