Apple iPhone 8 would be the best ever back up device that got 18 Hrs on use on 3G. And this will be also giving same for 4G. Recent report have revealed how Apple is going for a complete design overhaul to renew buyer interests after the iPhone 7 fiasco. Some reports have suggested that Apple could be looking to replace the aluminum unibody. But here we have another news for you. The iPhone 8 could have Lithium Ceramic battery.
A Lithium-Ceramic battery as the entire casing system for a future iPhone would allow for a substantially larger battery more than compensating for the lowered efficiency. This manufacturing technique would be revolutionary and create a thinner and lighter iPhone.
The battery made of high powered lithium with advanced technology will give more support to the system and then the phone will be working for longer than ever.
The journey Apple has taken to adopt Zirconia Ceramic as the their fundamental design material translates like an epic movie plot.
Lithium-Ceramic batteries are so resilient they can be cut in half and still operate. They are also a magnitude more safe and recyclable. The safety issue is currently a wide concern when it was discovered the Samsung Galaxy Note7 suffered a ban on airlines and a Consumer Products Safety Commission recall because of a explosion and fire hazard. Lithium-Ceramic batteries would be some of the safest batteries in use.
The Case For (of) Zirconia
Zirconia ceramics  are structured in a martensite-type  transformation mechanism of stress induction. This provides the ability to absorb highest amounts of stress relative to other ceramic materials including:
Zirconia ceramics exhibits the highest mechanical strength and toughness at room temperature. Zirconium ceramics have the highest fracture toughness of any advanced technical ceramic. Its toughness, mechanical properties and corrosion resistance make it ideal for high pressure applications.
