For example. My Galaxy S4 was purchased July 2013. Out of the box, I would return from home after heavy daily usage with approximately 50% remaining. Now, less than a year later, I struggle to make it a full day with drastically reduced usage, forcing me to purchase a Mophie Juice Pack.
I'm a mechanical engineer, not an electrical engineer, but have built plenty of aerospace turbines to be familiar with charging degradation. I also have an M.Sc Theoretical Physics so when problems become really abstract, I'm called on to solve problems; often turbine relation to charging amps/volts through the Brayton Cycle.

*ahem* "Hahaha battery quality matters too tho."
I am sticking with this. A junk battery is a junk battery. A lot of the top shelf phones use Lithium Polymer which has even fewer cycles than Lithium Ion, which makes the QUALITY matter even more. Now they are talking about silver like it will save them. But this is exactly the same issue encountered by anyone who owned say a DeWalt cordless tool, a Ryobi cordless and a Craftsman. The grade of battery still influences how many full charge cycles it will take.
At least as we move beyond li-ion there seems to be a reduced risk of explosions, but there are still li-ion hong kong counterfeits blowing up on the charger. You don't have an inkling to the endurance of your battery until anywhere from six months to a year after purchase, hence the rules concerning the battery in most electronics warranties.
.......and what did the last paragraph have to do with the topic? Please stay on topic here. One of the top sources of charge degradation in aerospace was still vibration damage last I checked. Between cooling and vibration many big ticket planes have been set back in their development. At least the turbines themselves can be tapped for very clean and stable power due to their rotational speed and momentum, hence why gas turbines are so loved by utilities.
