Iphone 4 Additional Battery Choice

[garrardrj]

Looking to extend battery life as gps drains the battery quickly. Looking at a Mophie Juice pack plus 2000mah.
Anyone got any other suggestions ?

I got one of these - you get all the connectors for different devices, can charge iPhone and iPad together - only used it a couple of times - charged it a few months ago and tend to leave in the car for emergency, used it last week and it worked a treat - still fully charged and got me some power.  Also charges at mains speeds not slow USB speed like the car charger.

I have one of these - http://www.amazon.co.uk/Juice-Pack-Rechargable-Battery-iPhone/dp/B0046EBTQ0/ref=sr_1_2?s=electronics&ie=UTF8&qid=1322738455&sr=1-2

Not really used it much but when I did it worked.

I have current battery issues since the final release of 5.0, Apple know it has effected battery and tried to fix it in 5.0.1 release but not fixed it for many of us.

wasnt one of the problems something to do with the auto setting of the clock - turning it off helped ..
