1. Battery case. For longer use without a need to top up.
2. Run of the mill rubbery case for some drop protection and anti-slip.

Please take your time to answer this short survey about your preferences on phone cases. I am a student who is designing a product for my IGCSE course and it would be very helpful if you could spare a minute of your time!
