Re: 48 hr battery my " you know what!"
They always through the "mixed usage" thing in there. If you have what we would consider light usage and what most people consider to be normal, you'll probably be able to eek two days out - but 48 is a silly number anyways. To get two full days out of a battery, you need about 42 hours, assuming you're charging at night every other day. And somewhere in the neighborhood of 6-8 hours of that will be sleeping, so doze takes over for that if you're not going to charge it overnight - so the device needs to be able to be used/idle for up to 42 hours, with only 34-36 of that being in motion, being used, etc. The obvious things like GPS, Screen, etc. are obviously still going to impact the overall usage. The 48 hour thing is a way of checking expectations, because it is relative to "normal" people. When the Moto X 2013, Moto X 2014 are both advertised to get 24 hours on the same "normal" usage, then the expectation, if you were getting 12 on those devices then it'd be reasonable to expect less than the full 48 advertised on this device. If like me, you were easily getting 16-18 hours (aka a full day) and charging each night out of those devices, expecting this device to last at least one full day and well into the next, if not the entire next day - might be pretty doable. Also, the OP has some wakelocks.
