Take Gary Ng, 27, one of them.

“If people are committing $1,000 a year for two years to use a 3GS, I would definitely expect my battery to last a lot longer,” said Ng, a loyal Apple fan who runs an iPhone blog from his home in Vancouver, Canada.

According to IFixit.com, repairing company which specializes in Apple products, the 3GS’s battery life was about 15% smaller than the original iPhone. But Apple spokeswoman Natalie Harrison emphasized, battery consumption is highly dependent on what applications and features are used.

That standby mode means the iPhone 3G can be left in the case, but reserve battery power kept back for when a user knows they’ll specifically need it.  An included USB cable and sync-through technology means the Mophie Juice Pack Air will both recharge itself and synchronize/charge the iPhone without requiring its removal from the case. 

• Standby Time: Up to 270 hours
• Talk Time: Up to 4.5 hours (3G) Up to 9 hours (2G)
• Internet Use: Up to 4.5 hours (3G) Up to 5.4 Hours (Wi-Fi)
• Audio Playback: Up to 20 hours
• Video Playback: Up to 6 hours

The Mophie Juice Pack  Air is available in Apple stores and from Apple.com online worldwide, priced at $79.95.  Black, white and purple color options are on offer; you can also buy the battery-case direct from Mophie themselves.

Mophie Announces Worldwide Availability of Juice Pack Air Accessory at Apple Stores and Apple.com

World’s Thinnest ‘Works with iPhone’ External Battery/Protective Case almost doubles iPhone 3G battery life and offers the full protection of a hard-shell case in a low-profile design

Los Angeles, CA., – April 21, 2009 – mStation | mophie today announced the immediate availability of Juice Pack Air, currently the world’s thinnest Apple-certified external battery for iPhone 3G. The rechargeable 1200 mAH battery, integrated into an ultra-thin case, is now available worldwide at Apple retail stores and Apple.com for $79.95 in black, white, and purple.

We think it’s poised to be one of the most essential iPhone 3G accessories ever introduced to the market.”

Juice Pack Air features an innovative “standby mode” that allows users to control when they want to take advantage of additional battery support versus simply using it as a protective case. The integrated 4 LED charge status indicates how much power is remaining in the external battery. Unique pass-through design allows users to simultaneously charge their Juice Pack Air and sync their iPhone 3G with iTunes via the included USB cable.

If a home-cooked meal is not that easy to find, then an energy beverage might be more the ticket. The Morphie Juice Pack is a rechargeable lithium polymer battery that says it will add up to an additional six hours of talk or surfing time to the iPhone. The pack adds about a centimetre of thickness to the phone while still offering a pass-through USB for syncing and charging.

The Morphie Juice Pack is available through selected retailers in Australia or online.

The passPORT Home Dock passes through audio, video, and data functionality to the iPod docks, making it fully compatible with the older iPod docking stations. Keep in mind this convertor is not a stand-alone dock and does not add audio/video functions by itself.

According to the ‘s Scoschesite, the passPORT is specifically designed to fix the charging error associated with several iPod docking stations.

Bundled with the dock adapter for Bose SoundDock I, it is available now from Scosche.com and Amazon.com for $39.99. It will be available also at Walmart in May.

This tiny, lightweight (just 1.4oz – 40 grams) Lithium-ion battery pack will provide up to 50% full iPhone charge. No need cords or adapters, just plug it directly into your iPhone (both versions).

You can use it in one of four ways:

• Directly from your computer via the Apple/USB cord
• Directly from the 110v Apple® USB charging cord
• Directly from any 12v Apple compatible car charger

The Incase Power Slider has a built-in 1,220mAh rechargeable battery that will recharge your iPhone 3G without the need for cables. Incase claims that this battery will deliver up to 330hrs extra standby time, up to 26hrs audio playback, up to 5hrs 3G talktime (or double that in 2G talktime), 7hrs video or up to 5hrs 3G web browsing (or 6hrs connecting via WiFi).

This battery also has an LED charge display similar to that of the MacBook Pro batteries. If your going to pick one of these up your wont have to wait much longer. They are going to be on sale starting November 28th for around $100.  This may be a bit more than a typical backup battery, but it holds more of a charge.

Charging your Apple device is easy, just turn on the battery and plug it in.  The iPWR has a few features that other backup batteries do not have. Other backup batteries require you to take off protective cases in order to use them but with the iPWR, you can use it without removing the case. The battery can be charged by micro USB rather than requiring an iPod USB cable. This battery is far more portable and attractive looking than any other we have seen.

We recommend this product to anyone looking for improved battery life. iPWR is perfect for those who are always on the go and need the extra battery life but do not have a chance to plug their device in for a few hours. Other competitors batteries have capacities of 1200mAh (Richardsolo) or 1000mAh (Kensington). Although the capacity of the iPWR is only 50% more than RichardSolo and 80% more than Kensington, power delivered is much more efficient. Compare below the real power delivered to iPhone 3G or original iPhone with the iPWR and its competitors.

1 iPWR battery = 2 Richardsolo batteries
1 iPWR battery = 2.7 Kensington batteries

The iPWR is certified to meet Apple performance standards with a capacity of 1800mAh and output of 5.0V. This product is imprinted with “Works with iPhone” and “Made for iPod”. This is the smallest iPhone backup battery with the highest charge capacity that you will find on the market today. An interesting fact about the backup battery is that, unlike other products, it uses true-shutdown circuits that enable it to hold a charge for several months to a year without use. Currently the iPWR is only available in black but white will be available in the future.

I find it ironic that Apple takes every effort to make sure our user experience is nothing less than the best, even right down to what applications are allowed on iTunes; yet they can’t seem to get the battery right.  I counted ELEVEN different things you should do to your iPhone 3G daily in order to ensure that it DOES NOT die on you during that oh so important sales call or while chit chatting with your wife.  We’re busy people, not to mention busy enjoying the awesome 3G speed surfing the web, getting push email or trying to hook up with an old friend on Loopt.  The last thing we need to be concerned with is — turning off EQ, making sure push email is off or worried if I should fetch my email less (the list goes on and on and on!).  This is nonsense! Of all the suggestions, this particular one gave me a few chuckles.

Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.

I’m not sure if it’s even possible to improve the iPhone 3G’s battery at this point, so I’ve resolved to the fact that the battery is a piece of junk and it should be criminal of Apple to release such a superior device on an inferior battery!  At this point there’s nothing I can do, and you must be feeling the same.  There is some hope; third-party battery extenders.  There are three brands/makes that I know of: Mophie Juice Pack, iGo battery extender from Mobility Electronics or the Kensington Mini Battery Pack and Charger.  Check out the video for more details on the first two, and jump on over to Geek.com to read up on the last one.
