I need some sort of battery backup for the iphone, as im always running out by 9pm each night.

iZAP looks ok, but there are so many of them. Any opinions on the best???

THere are cheap $5-$10 ones on ebay that use AAs too

I don't have an iPhone, an iZap, and I've never used any backup battery product. HOWEVER, I'd suggest going with one of the disposable battery backup systems because then you never have to worry about your backup not seeing you through the demand you require of it, because disposables are super cheap in bulk and available everywhere in the industrialized world. And if you care about the environment you can buy a AA rechargeable battery system for cheap and have the best of both worlds.
 
I am actually not sure the iZap works. There is some pin funkiness going on regarding power sources. I would confirm with the company the battery works with the iPhone.

I use the javoedge rechargeable battery. It will not work with the iPod or iPhone cables for the iPhone but it will work with their multi-tip cable.

The javoedge battery is about the size of an iPod classic. I have used to recharge devices in long battery trips. From one battery charge I have recharged multiple times an: iPhone, iPod with video, PSP, DS lite, digital cameras etc. I still have to run out of juice from the javoedge battery on a trip.

Cheers.
 
so is the javoedge the best on the market now?? any others to look for?
'p

does anybody have the javoedge.. is there anything better?
 
Some notes about backup batteries

I have both the Javoedge portable power pack as well as the iZap M48. The Javoedge recharges the iPhone twice before it dies. The M48 is a trooper and can recharge it 6+ times. Be aware that the M48 does NOT work with the normal iPhone sync cable, and you need a special USB charging cable - the one sold by Javoedge works great.

Final comments: It wonderful that I don't have to take my laptop or a charger for week-long trips anymore. Hope this info helps!
 
wow, i can't imagine running out of battery every day or close to it. that is some very heavy usage. impressive. even if i use mine heavily on a particular day i still have almost 50%.

When visiting my parents recently, I found out in the new house they just built I got really terrible reception on my cell phone. While staying there, my battery would easily run out by the end of the day. Even not using it much except for email and the occasional demo/ipod usage.

Moral of the story: it can happen. Especially if you have poor reception in your location.

same here. I've noticed though that since I've been at home and not at school the battery life has been draining a lot slower. I guess since I'm closer to metro atlanta opposed to savannah.

Oh well, still haven't had a problem with battery life since day one.
 
Check out the Lenmar Powerport from Radioshack. Really slim and nice. $40.
 
If you aren't using the GPS function, turning it off also helps increase battery life, as does turning off the search for wifi, unless you are ready to use it.
 
Get the Incase Power Slider case. Doesn't add much bulk,and with a fully charged 3G iPhone you will last for atleast 16 hours.

Ha ha, well I'm sorry you have such a poor imagination.

My phone lasts about 10 hours of standby, on average, with 3-4 hours of use during that time.

And by "average" I mean that sometimes I get 14 hours and sometimes I get 6 hours.

I charge while I sleep, I charge on the drive to work, and I charge on the way home. Those 3 charges per day tend to be all I need, for the most part. If I play video games on it at night I might have to plug it in while I'm doing that, but if I use it like a normal phone and web device then 3 charges per day is normal.
 
I got me two Energizer Energi-to-go and gave one of them away on a woot two for tuesday. Best 25 bucks I've spent on the iPhone 3G. Charges fast, and lasts me what I need it to. Small and foldable so it's easy to carry around.

I use this. Unlike Mophie, this has a little flash at the rear which allows for night illumination when taking photos. Allows for a 2.5X charge for me.

Great that it has another USB port at the rear so its handy for charging any appliance that has a USB port, such as a PSP or digicam. Likewise, Mophie does not have this.

Purchased mine from the Fast Mac site direct.

good thing this 2 year old thread was resurrected...
Wish I could always be sure what is sarcasm and what is not... As a new iPhone 3GS owner (who finds I can easily use up the battery in just a few short hours of heavy use), I do find value in this thread, and hope it can be updated, as I'm sure there are new battery backups that should be included.

I love my Mophie Juice Pack Air...it is the thinnest of all the case/battery combo's I have seen...it doesn't quite have the huge battery of some others but it's 1200mah is enough to give me a full charge and about half more...all that I would ever need. I was happy to sacrifice some extra power for a thinner design...I also haven't experienced the signal deterioration that some have mentioned with these hard cases...
I've already dropped my 3GS with the JPA on it and aside from a scuff on the corner of the JPA, not a scratch on the 3GS (and I dropped it right on the street from my pocket :eek: )...
