The key thing to remember when trying to max out your iPhone's battery life is that the less your iPhone is doing, the longer it will last....
The Apple iPhone 's battery life has been a topic of some debate - and quite a few lawsuits - since the iconic handset first appeared in June 2007.
Because the iPhone's battery isn't easily user replaceable and lithium-ion batteries inevitably degrade a little every time they're recharged it's important you get the most out of iPhone's battery while it lasts.
(Incidentally, Apple estimates that after '400 recharge cycles' the battery will still retain 80% of its original power, but inevitably people may find real life scenarios are less optimistic).
The key thing to remember when trying to max out your iPhone's battery life is that the less your iPhone is doing, the longer it will last. So if you're constantly checking for mail, surfing the web, making calls and listening to music your iPhone will conk out that much quicker.
But there are also some background processes - such as W-Fi, Bluetooth, keyboard clicks - that eat up precious voltage constantly. Ask yourself if you really need any feature to be in an always-on state. If the answer's no, then turn it off and enable it when you need it.
So here are our top 10 tips for improving your iPhone's battery life. You may not be able to extend it to Apple's mythical claimed maximum of 250 hours of standby time, but you should be able to eke out up to 20-25% more battery life if you follow all of them.
Top 10 iPhone battery life tips
1. Store and use the iPhone at room temperature
Direct sunshine or putting the iPhone in the glove compartment of a warm car will cause your iPhone's battery life to drop sharply. The iPhone functions well between 0 degrees centigrade and 35 degrees centigrade (32-95� F).
You should store your iPhone in conditions between -20� C and 45� C (-4� F to 113� F).
The ideal battery life environment for both usage and storage is room temperature: 22� C (72� F).
2. Change Mail autochecking from every 15 minutes to every hour

If you don't need to use Wi-Fi constantly then you will get better battery life by turning it off and then enabling it when you want to browse via a hot spot.
4. Turn off Bluetooth
5. Reduce the display's brightness

8. Enable Auto-Lock
Better still, if you can get into the habit of locking your iPhone yourself simply turn on the Auto-Lock feature:
9. Turn off keyboard clicks
If you regularly use the iPhone's touch keyboard then the constant need to generate audio keyboard clicks can add to the iPhone's power consumption. To turn off keyboard clicks:
10. Turn off the music equalizer (EQ)
The iPhone's audio equalizer may add some oomph to the songs but it also delivers a powerful blow to the handset's battery life because of the constant processing it requires. To turn off the EQ:
