Approximate Cost of Design Waterproofed items Approximate Cost to Waterproof
(per phone)
Main board $20
Antenna $0
Speaker $1
Microphone $1
Battery Case $.50-$1.00
Camera $0
Touch Screen (software/hardware) $1
Charger software/hardware $1
Testing $5
Labor Cost of Manufacturing $3
TOTAL* ~ $33 + base phone
*this is an overestimate of the cost; waterproofing components such as the microphone and speaker may cost a little less
