It looks like the Nexus 6 is only coming in a 6 inch (5.9 inch) size, and the price will be north of $500, so the Moto X 2014 Pure Edition (with Android updates that aren't slowed down by the carriers) is looking VERY attractive. I want to see how easy it's going to be to replace the battery on Moto X 2014.
When these Lithium Ion cell phone batteries get old they tend to "pillow", get puffy in the middle. My HTC phone is suffering screen problems because the battery swelled up under the screen and damaged it. A non-replaceable battery is planned obsolescence, which only benefits the carrier and the phone manufacturer.
