Comparing a Moto Mod accessory attached to a device vs.competing stand alone products.
Yeah the title "Mod Delivers Best in Class Smartphone Battery Life" I would imagine a way over the line of performance, not on par with other smartphones already on the market. There was one or two where it actually took the lead but in general it was on par with Samsung's Galaxy phones, which was disappointing.
The internal battery constantly being charged by the external should be a negative. That kind of wear and tear on a non removable internal battery is going to leave a moto phone with a useless battery in short order. At least far before the rest of the hardware is worn out.
I think my friend, you are stuck on the NiCd era. Just a heads-up, recommended and encouraged use for Lithium batteries is to keep them over 50%, that way they will live longer.
I wonder why motomod doesnt offer the ability to use the external as a second battery ala apple's smart battery case, which doesnt charge the internal, rather the phone directly drains the external battery first.
I'm not sure what you actually mean, Apple doesn't have any smart battery case, everything is 3rd party for what a friend once explained me. Anyhow, we have no idea how internal circuit works but I'm pretty sure this is part of standard logic. I doubt they make things to actually reduce hardware life.
I must be using my HTC 10 all wrong then, I often find that the battery can last almost 3 days on a single charge.
They do standardize the tests, so I doubt that you are "using it wrong" but you are not using it the same way the tests go.
