How does an external battery pack/case affect the 'life span' of the original in the phone, Do the charge cycles remain the same ?

✔ Best Answer
When you plug in a battery pack, it doesn't become an extention battery perse but it acts like you are pluggin in the AC adaptor and will charge the battery as well as powering the device. Yes, the charge cycles will remain the same as if you are using a AC adaptor.

In terms of the correct voltage for the iphone 4, which external battery case would you recommend that is really sleek ?
I'm not looking for rapid charging OR a full 100% charge.

The voltage will always be the same, it will be a 5 volt output just like the AC adaptor, and the charge time will remain constant as well. If the battery pack is designed for an iPhone or iPod device, it will have an ouput of 5 watts or more. If the pack was designed to charge iPads as well, it will have an output of 10 watts or more. What you want to look at is the milliamp hours (mAh). The larger the number, the larger capacaity of the battery and the longer it will charge.

I can't really say what would be best for you as everyone has their own needs, it just depends how long you need to run your phone between charges.

Personally I use the Mophie 2000mAh battery case. It fits on your phone just like a regular case does and has a switch to turn on and off the charger.
