There is a lot of conflicting info out there about the state of batteries, a lot of politics in it. I still believe that past performance is indicative of the future of batteries but it is nice to know that there are some possible solutions to this problem.,(reply>), @David Linn's Subliminals Skip the Note 4 and try out an LG V20. My note 4 suffered the inevitable emmc memory error that will kill them all eventually. I'm pretty happy on the V20 !,(reply>), @sparkyenergia Well, this isn't entirely true. Take Optima automotive gel-based batteries: they charge up to three times as fast, hold a lot more amount of energy, provide more start-up amps and last about 20 years of service in comparison with regular led-acid batteries. And think about what is already in works for the coming folding transparent phones ant tablets, there will be other technical solutions (alloys or composites) in use that will replace lithium as a base component in batteries. The future is not that bleak, keep on rollin', baby! ;-),(reply>), @mascar1lha yes I still use samsung note 3 :D,(reply>), There is phones without swappable batteries??
