will i have to get another iPhone when the battery inside it cant keep its charge any longer.
That would blow to have to send your cool phone off every two years to have the battery replaced. I hope they have a better plan than that.Apple will charge you for the new battery. They may (not Apple they as in general) release a kit to allow you to change the battery by yourself.
If Apple doesn't, someone else will. By the time iPhone batteries need to be replaced I would be surprised if there aren't do it yourself kits (like the ones for iPods) available. They will probably even have batteries with higher capacities than the one(s) that were originally installed.That would blow to have to send your cool phone off every two years to have the battery replaced. I hope they have a better plan than that.
Now that it has come out that At&t will be offering the iPhone with pre-paid plans, I'm thinking there may not even be a contract requirement. I'm starting to think more and more than the $499 and $599 is an unsubsidized price to any Cingular user current or new. If all that's true, then I don't think it will matter whether or not you're up for renewal or upgrade.Hmm 2 year contract 2 year battery life
Check out Wikipedia's iPod Models.That's true, but they've been out for six years haven't they? How long did it take before they started dropping in price? And wasn't some of that reduced pricing due to flash memory?
That is not true of current iPod batteries. With older technologies, batteries had "memory" and it was best to completely discharge them regularly. With current batteries if you let the battery completely discharge you can damage the battery.I heard that if you wait until the charge completely dies or close to it the battery lasts longer.
* Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.
* Lithium-ion batteries should never be depleted to empty (0%).
* Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.
* According to one book, lithium ion batteries should not be frozen (should not be stored under -40 °C), because most lithium-ion battery electrolytes freeze at approximately −40 °C (this is much colder than the lowest temperature reached by household freezers, however).
* Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.
* When using a notebook computer running from fixed line power over extended periods, the battery can be removed and stored in a cool place so that it is not affected by the heat produced by the computer.
Oh, very nice.That is not true of current iPod batteries. With older technologies, batteries had "memory" and it was best to completely discharge them regularly. With current batteries if you let the battery completely discharge you can damage the battery.
Wikipedia has good info if you want to know more.
Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate. (Read more in 'Choosing the right battery for portable computing', Part Two.)
