POWER PRIORITY

The iPhone4 will continue to use the battery until the MiLi’s remaining charge is less than 5 percent. When the MiLi battery is less than 5% charged, the internal iPhone4 battery power source is used. The iPhone battery power source is always used last so it can maintain its maximum charge.

* 3rd Priority: iPhone4 switches to internal iPhone4 battery
Thanks to MiLi’s smart chip you can extend your overall iPhone4 battery life by using the iPhone4’s internal battery only when it’s absolutely necessary. Leave your MiLi to charge and re-attach to the iPhone4 as needed. Just disconnect the iPhone4 from the MiLi and you will have a fully charged phone to take with you.

So far so good 3 Nov 2010
Battery seems to work - but after half an hour of listening to music it switched to phone battery.
This did not happen with my previous same brand charger for the 3GS. Perhaps with a few more full charges things will improve!

Longevity - Not sure about the top of the unit. The hinge is a piece of rubber tape that could be a weak point and it aint the greatest fit with it keep opening.

Overall cheaper by half than another popular brand and I am not sure yet if my investment in this particular model will pay off.
I would suggest a full review of chargers such as this is researched - cheaper is not always the best.

Ok-ish 8 Nov 2010
I bought this and the Mophie one to try both in the same month. While this is actually an OK design, and lighter than the mophie, there is a fundamental problem in that you can't switch off the charge once its started... unless you take it out of the phone and then put it back in. Also, I worry (subjective view only) that the hinge would not be so great after taking the phone out say, 50 times. Sorry MILI, but needs work.

No good at all! 30 Jan 2012
I must have bought 3 of these in as many months! They seem to work fine for a couple of weeks then refuse to charge completely. After plugging into my PC USB socket, the Milie's blue flashing light just keeps flashing after 12+ hours with no charge getting to the battery!

doesn't last
Initially I was happy with the case. After a few weeks the hinge became loose and would not stay in place. After 3 months the battery only provided five minutes of charge.
