So here’s a major glitch with the iPhone. And it’s so big that a class action lawsuit was filed against Apple for the same. It seems the battery of this here revolution in the tech kingdom, is only good for 300 – 400 charge cycles. Once you’ve crossed that bar you’re going to have to send your precious iPhone back to Apple who’ll charge you a fee of approximately 75 USD (Rs. 3035) to replace it, this being due to the fact that you can’t replace the battery yourself since the iPhone is very much like the iPod. The battery is soldered into the device hence the rear panel isn’t designed to be removed.
Besides the fact that you’ll have to pay to Apple to replace the battery pack you’ll also have to pay them a fee if you want to have a replacement while they tinker with yours. That should set you back another 25 USD (Rs. 1011) or so. So you’re going to have to shell out about 100 (Rs. 4047) USD just to get the battery replaced. No fakes here.
Though the information on the battery charge is clearly evident in writing when you purchase the device the costing for a new one is not mentioned. So, till there's an alternative solution to the iPhone's battery woes, I'm going to seriously reconsider my purchasing one.

That's 300-400 FULL recharges of the battery, not every time you top the battery off. If you recharge when it's at half capacity, then that's HALF a cycle, not a full one. My use of the iPhone drains the battery once every 3 days, meaning that my battery wont be affected at this rate for another 900-1200 days. Even then, after the 300-400 FULL charge cycles, the battery will still charge, but only at 80 percent capacity. The average user wont go through 300-400 full cycles before 2 years, at which point most will be upgrading to newer phones. People have got to stop this insanity over the battery in the iPhone. It's the same battery tech that can be found in most other phones. The only difference is you can't replace it easily, but if you read the facts, you'll realize you wont need to!
