Foxconn rumored to be examining glass phone enclosures for 2017 iPhone
Apple manufacturing partner Foxconn is reportedly looking into all-glass enclosures for future mobile devices, reiterating previous rumors slating a new design and enclosure for an iPhone to be released in 2017.

While no specifics of the process were revealed to the Nikkei Asian review, sources familiar with the matter confirmed that there were developments, saying that "Foxconn has been trying glass chassis since last year."
An additional source said that a successful development of an all-glass case would lead to future orders placed with Foxconn from other vendors. While Foxconn is the main aluminum casing manufacturer for Apple, it is not currently a glass supplier.
The 2017 model of the iPhone has been rumored to incorporate a new all-glass enclosure to differentiate it from competitors, possibly in a 10-year anniversary model of the iPhone. While a glass casing would be heavier than an aluminum one, the weight difference is expected to be offset by the addition of an AMOLED display.
The iPhone 4 family was the first iPhone to feature front and back glass panels. Apple was criticized about the glass in the 2010 iPhone model, but with normal care and handling would collect only "incredibly minor" scratches. While the company was hit by lawsuits over the durability of the glass, they were ultimately tossed out.
The glass in the iPhone 4 and 4s was the second revision of Corning's Gorilla Glass, with the iPhone 6 family using Gorilla Glass 4. Subsequent changes to the formula of the glass has added both more scratch resistance, and further impact protection.
The fifth iteration of Gorilla Glass was recently announced, and is present on the Samsung Galaxy Note 7, with Corning expecting wider release later in the year.

I believe they hoped to do it with iPhone 4 or 4S and the technology just didn't pan out. They've had the time to work it out, and they will once again leap 5 years ahead of everyone else with an glass front/back phone that has solar receptors under the glass, as part of solar supplementation system that extends normal battery life by unimaginable lengths.
I firmly believe this to be not just a patent, but a goal..and the primary reason for returning to the Glass device.
In all seriousness, @TurboPGT has a novel and interesting idea, tho Apple would have to change its user's habits, as you mentioned above, which is too tall of an order, IMO.
I don't really like glass design - didn't like iPhone 4 and 4s either, and don't like new Samsungs just as much. Sure it is all matter of taste, but as far as my taste goes. I do like idea of solar panel/battery topping up, though... even better if panel is efficient enough to fully charge battery, not just slow down discharge.
But... how is that going to work, really? Majority of time, phone is:
In pocket - no light
In hand, covering rear - no or very little light reaching rear side
On table - again, no light reaching rear, unless phone is screen down. Which wouldn't make much sense in everyday use, but can be handy if one needs some battery top-up and hasn't got any other charging option available.
I can think of very few scenarios - like car windshield holders (or bicycle holders), designed to cover as little of phone's rear side as possible... though in car, I can plug phone to charger anyway. I guess charging from sun through windshield is more hassle-free, and cool. Still, most of the time rear side of the phone will be hidden.
Well, the patent describes a solar cell beneath the touchscreen, NOT on the back of the device- so I imagine it would work fine with a case.
Blocked for idiocy.
