PC World reported that you will soon be able to check your car battery with your iPhone. This could lead to many bigger things like charging your iPhone with your actual car battery (hopefuly)!

Via PC World: Nissan has developed a prototype iPhone application that would allow electric car owners to dial into their vehicles and check battery levels.The application, a working version of which was demonstrated by the company at its research facility in Yokosuka, Japan, links to the car’s IT system to check the status of the Lithium Ion batteries that power the car. Using it, owners will be able to monitor charging of their cars while away from the vehicles.

The system could come in handy, for example, when cars are parked at public charging stations and owners want to fully charge the batteries before driving away. In addition to the basic monitoring of battery level, more detailed information can be sent to the phone that includes the time required for a full charge and the approximate cost. The information also includes the current temperature inside the car and that ties into a second function of the application: remote control of the car’s air conditioning system. That might sound like a random and perhaps strange function but it’s all in the name of energy efficiency.

A driver returning to their car on a hot or cold day will typically blast the air conditioning or heater as soon as they start the engine and keep it going until a comfortable temperature is reached. That doesn’t pose too much of a problem on a gasoline-powered car but on an electric car it contributes to battery drain, reducing the car’s range. However if the car is connected to a charger then it makes more sense to start-up the air conditioner or heater while still connected, making use of the electricity from the charging station, for those few initial minutes of high power use.With the iPhone app, owners will be able to switch on the air conditioning before they arrive back at the car.

The system is still a prototype and part of Nissan’s research towards the 2010 debut of a production electric car in Japan and North America.

I was browsing digg and found this story.

1. Keep it cool
Seriously. Don’t put your phone in the sun. Don’t leave it in a hot pocket. Battery life is lowered by heat and you should store your iPhone in temperatures less than 35 degrees centigrade – below 95F. As close to room temperature as possible is best for use.

2. Don’t use power-sucking apps you don’t need to
Minimise your app use, especially if it’s a game, stuff that sucks data (hello, Facebook) or uses GPS. Not only does some of the fun stuff suck power, it can also stop the auto-lock coming on.

3. Turn off 3G
So there we were, in our field, with little data coverage (thanks O2). So what did we do? Turn off data, that’s what. If you haven’t got it, there’s no point in wasting juice looking for it. Settings > General > Network and slide Enable 3G to Off.

4. No to EQ
Who’d have thunk, but equalising your iPod playback can drain your battery pack. Settings > iPod > EQ is where to turn it off.

5. Don’t fetch
Set the common apps to only fetch data when you want them to. Set Mail, Contacts and Calendars to only fetch data Manually. BE WARNED – if you have MobileMe, it’s dangerous to set the auto-check to Manual, since the much-vaunted Find My iPhone won’t work.

6. Don’t make long calls
Or don’t make any calls. Sounds like the stupid filler tip, but if you do make calls (and you probably do, as that’s almost certainly what you’re conserving battery for), just keep ‘em short.

7. Lock it up
iPhone not in use? Make sure you lock the screen and set the auto-lock to a minute in case you leave it unlocked.

8. Don’t use the GPS
Minimise use of it (such as in Maps or turn-by-turn sat-nav) and disable it: Settings > General > Location Services. If you’re lost, ignore this advice.

9. Turn it off when you don’t need it
Sleeping? With all your mates anyway? Then turn your phone off. Bit pointless if it’s for 10 minutes, but if it’s hours, it will add up.

10. Disable Wi-Fi
Nowhere near a wireless network? Go to Settings and slide Wi-Fi- to off. However, if you are going to be doing a fair amount of data browsing and you are near a wireless network, it will be better for your battery to use this than the thirsty cellular signal.

11. Turn off Bluetooth
Likewise, make sure Bluetooth is off. And keep it there unless you use accessories: Settings > General > Bluetooth and slide Bluetooth to Off.

12. Push off
Not many apps use push notifications, but in the future this will have more of an effect on your iPhone’s battery life as more start to. Settings > Notifications and slide Notifications to Off – only visible if you have relevant apps installed. Apple says this won’t stop the apps receiving data when the app is actually open though, so be careful, unless you’ve disabled data in other ways. Equally you need to turn off push mail (MobileMe, Microsoft Exchange). Go to Settings Mail, Contacts, Calendars > Fetch New Data and slide Push to Off.

13. Turn it down
Refrain from employing the speaker for music playback and turn down the volume – louder playback can make a difference, even with the headphones. Set the phone to silent on the side.

14. Dim your screen
Turn off auto-brightness and whack the brightness down as low as possible. Especially effective for many of us, as it’s the supreme brightness that’s one of the things that makes the iPhone screen look terrific, so it’s usually very bright as a default.

15. Go airplane
If you’ve got very little coverage, you can’t make calls anyway. If you’re going to be in a coverage lowspot for a little while, turn on Airplane Mode. It makes a serious difference, since your handset won’t be continuously searching for a network signal. This is one of the biggest drains of battery life on any handset.

I am sure most of these will work for the iPod Touch also.
