How to Extend Your IDevice's Battery Life

 
When you get an iPad, an iPhone or an iTouch, you have made a sizable monetary investment in your technology. You're also relying heavily on the device's battery to keep running and connected. With the help of a few common sense tips, you can make sure your iDevice of choice gets the most out of its battery. That will prevent you not only from having to swear at your phone in the middle of a road trip, but also from having to pay Apple to replace it for you.

1. Keep it Out of the Light

Using your iDevice in direct sunlight for an extended period of time will hurt your battery, and make it harder to hold a charge (not to mention the overheating issues). Keep it at about the same range of temperature as your own body and you will be fine.

2. Turn Down the Brightness

By turning down the brightness on your screen, you will reduce the amount of battery that is used to keep it lit. You do not have to make it so dim that you have trouble seeing, but choosing the lowest setting that's still comfortable for you will help. In iOS5, Brightness can be found directly under the Settings app.

3. Use Wi-Fi Instead of 3G When You Can

Using Wi-Fi instead of 3G will enhance your battery life by about an hour, according to Apple. So, when you have the choice, take the time to connect to the Wi-Fi network for your browsing. The additional bonuses here, of course, are that it's faster and that you'll save your data download limits when you need it.

4. Keep Push Notifications to A Minimum

Every time you receive a push from an app, you are forcing what may be a sleeping phone to wake up, and that uses up your battery life. Since the odds are that your friends' Facebook statuses are not that critical, save the push only for the most important of information.
How to store your battery?
Keep your battery in a cool and dry storage area.
Do not fully charge your rechargeable batteries before storage.
Do not store your battery fully depleted.
Do not stockpile your laptop batteries and avoid buying dated stock.
Never leave a nickel-based battery sitting on a charger for more than a few days.
Always store a lead acid battery in full-charge condition.
Observe the open terminal voltage and recharge the battery as recommended by the manufacturer.

iPhone Application Development: How to get started?

Without doubt, the iPhone is the most loved platform for the masses. While the ever-green PC is forever building on its success stories, it's the Apple's handset, which is turning out to be the real Mecca of the enterprise culture. And why not, when you can have an iPhone application done and put up for mass downloading, all in under a month!
It all comes down to getting a head start, if you look to make big on your iPhone Application Development. Prima facie, it's apparent you got to be roping in development specialists, iPhone programmers, publishers etc.
But hang on!
How about self-developing your own iPhone app from the ground up? After all, Apple's iOS is open to all, and with a little bit of efforts going into the right direction, you could well be a self-proclaimed iPhone developer.
So, why not gear up for a start?
The Apple SDK (software development kit)
Apple provides the free SDK for iPhone development from their Developer site. This should be your start point. The SDK is a whole caboodle of tools you shall need for iPhone application development, including the development environment Xcode, the iPhone Simulator for testing, performance analyzers, interface builders and the full documentation reference library.
Mac for quick iPhone App Development
Although PCs can be a replacement for Mac, they aren't the best when it comes to mobility. Mac is a real powerhouse, which is easy to move around and provides the luxury to work no strings attached--even on the go.
There is no need to go for a top-of-the-line version; just get a Mac on an Intel-based processor, and if possible, running the Leopard version of MacOS X.
Objective C
This is the primary programming language for iPhone development which has scripting elements built into it. It's is easier to pick up than some languages and anyone with a little bit of programming should be able to crack C like a breeze.
Objective C in many ways is similar ways to Java; it deals with many of the problematic parts of programming. It's simple and non-convolute; hides the complexities of the hardware away from iPhone developers, and deals with (on the whole) the major cause of programming issues in C and C++ which is memory leaks.
Get off writing something!
Forget theory; forget mastering Objective C with your first attempt. Just set yourself a project and start working. The SDK actually gives you a first-hand -feel of the iPhone development process with a whole host of sample projects to work upon. Just pick one and start off; reverse engineer and add your own creativity to the mix.
Register as an iPhone Application Developer
Before you plan to break your masterpiece to the world, you'll need to sign up with the iPhone Developer Program. The protocol involves agreeing to Apple's terms and conditions, no matter what levels of completion you have achieved on your iPhone application development. Even if you're nowhere near completing the project, you'll need to sign up in order to test your code on an actual iPhone rather than an onscreen emulator.
The Business End: Submit the iPhone App
This is finally the big one. Any iPhone application needs the consent of the Apple Store. It takes no more than zipping up the file, uploading it with a description, a large and small icon, and adding screenshots. Apple takes about a week to review and approve the app. If however, the application runs into bugs, you will have to resubmit to Apple again, once the issues are fixed. In such cases, your iPhone app shall take bit longer to come through Apple's approval process.
