You'll want to check out the Moto G/X line then, I'm a happy Moto G owner, and that thing lasts a good 36-48 hours without a charge (admittedly, mine is a year old now, and can only take 24h without a charge) and the hardware isn't completely low-spec. Not to mention it's about the same size as the iPhone 4. Great battery life, packed into a small handset.
