World Famous Warranty
At Anker, we believe in our products. That's why we back them all with an 18-month warranty and provide friendly, easy-to-reach support.

For Optimal Use:
• Use the included cable. Other cables may not charge or sync successfully.
• Turn off the case before recharging it.
• Use an Anker or Apple charger to charge the case.
• Before using the audio jack extender, ensure that all audio functions are working as normal. Always ensure it is fully inserted during use.

Note:
Not compatible with iPhone 6 Plus or 6s Plus.
This case is not designed to provide screen protection.
Battery heating, draining quickly and poor battery life could happen with the ageing and constant charging/discharging circles on most cellphones including iPhone6/6s. A battery case can charge your iPhone but can not improve the iPhone's own battery life.
It is advisable to check the internal battery condition at the official Apple store if you noticed your battery perform worse.
This case is not waterproof. Use only in dry environments.
