Does the i4 work with the iPhone 4S?
Yes, the i4 works with both the iPhone 4 and iPhone 4S.
Can I leave my i4 powered on even after my iPhone has been fully charged?
Yes, but we recommend you turn on your i4 only when you need to charge your iPhone. Once your iPhone is fully charged, turn off the i4. There are two reasons for this: like any electronic device, the i4 does use a bit of power while it is turned on, even if it is not charging your iPhone. Also, the iPhone uses additional power to be on a constant charge.
How do I recharge my i4?
Connect the i4 to a power source using the USB cable that came with your i4. The USB cable can be plugged into a computer or into a standard AC outlet via a USB power adapter that was made to work with iPhone. You can either charge the i4 with the iPhone inserted or charge them separately. If you charge the i4 while your iPhone is inserted, both the i4 and the iPhone will be recharged.
Can I recharge my iPhone while it is in the i4 case?
Yes. The i4 was engineered so that you can recharge your iPhone while it is inside the i4 case. In this situation, both the i4 and the iPhone will be recharged.
Can I recharge my iPhone in the case using the Dock Connector to USB Cable that came with my iPhone?
No. You cannot plug the 30-pin Dock Connector to USB Cable into the i4 or the i4 dock. However, you can still recharge and sync your iPhone while it is inside the i4 case using the supplied USB cable. You can recharge using the i4 Charge/Sync Dock, or by connecting the USB cable directly to the i4 case itself.
Can I sync my iPhone while it's connected to the i4?
You, you can sync your iPhone to iTunes without removing it from the i4. Both the your iPhone and i4 will also be charged while you sync.
Can I recharge the i4 in my car?
Yes, you can use an in car charger to recharge your i4. Just make sure the in car charger you use is Apple certified. Also, as with other charging methods, you do not need to remove your iPhone from the i4. Both will be recharged at the same time..
Can I leave my i4 in the dock or connected to a power source even after it's fully charged?
Yes, leaving your fully-charged i4 connected to a power source will not harm the i4 or the connected iPhone. The i4 is equipped with intelligent circuitry that prevents overcharging and overheating.
How many times can you recharge the i4 case?
The i4 is rechargeable for well over 500 FULL cycles. Partially recharging your i4 or iPhone does not reduce the total number of full cycles, so don't be afraid to top up your i4/iPhone. After 500 cycles the i4's capacity will be about 75% of the capacity when it was new.
Does the i4 block the speaker, microphone or video camera?
No. Unobstructed access to all of your iPhone's controls, ports, inputs and outputs are retained.
Does the i4 interfere with antenna reception?
Will the i4 block the camera on the back of the iPhone?
