iphone Battery life of apple iphone
The iPhone features an internal rechargeable battery. Like an iPod but unlike most other mobile phones, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, a USB to AC adapter (or “wall charger,” also included) can be connected to the cable to charge directly from an AC outlet. A number of third party accessories (car chargers, portable chargers, battery cases, stereo dock chargers, and even solar chargers) are also available.
Apple runs tests on preproduction units to determine battery life. Apple’s website says that the battery life “is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles”, which is comparable to iPod batteries. The original iPhone’s battery was stated to be capable of providing up to seven hours of video, six hours of web browsing, eight hours of talk time, 24 hours of music or up to 250 hours on standby.The iPhone 3G’s battery is stated to be capable of providing up to seven hours of video, six hours of web browsing on Wi-Fi or five on 3G, ten hours of 2G talk time, or five on 3G, 24 hours of music, or 300 hours of standby.[50] Apple claims that the 3GS can last for up to ten hours of video, nine hours of web browsing on Wi-Fi or five on 3G, twelve hours of 2G talk time, or five on 3G, 30 hours of music, or 300 hours of standby.
The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple’s claims.This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the “battery aspects” of the iPhone 3G its lowest rating of 2 out of 5 stars.
If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty. The warranty lasts one year from purchase and can be extended to two years with AppleCare. Though the battery replacement service and its pricing was not made known to buyers until the day the product was launched, it is similar to how Apple (and third parties) replace batteries for iPods. The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced. Since July 2007 third party battery replacement kits have been available at a much lower price than Apple’s own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the original iPhone has been soldered in. Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace, although replacement by any besides Apple still voids the warranty.
Apple – iPhone 4 – One-tap video calling with FaceTime on iPhone 4
People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 or to the new iPod touch over Wi-Fi. No other phone makes staying in touch this much fun.
One-tap simple.
FaceTime works right out of the box — no need to set up a special account or screen name. And using it is as easy as it gets. Let’s say you want to start a video call with your best friend. Just find her entry in your Contacts and tap the FaceTime button. Or maybe you’re already talking on a voice call with her, iPhone 4 to iPhone 4, and you want to switch to video. Just tap the FaceTime button on the screen. Either way, an invitation pops up on her screen asking if she wants to join you. When she accepts, the video call begins. It’s all perfectly seamless. And it works in both portrait and landscape modes.
Two cameras made for video calling.
iPhone 4 has two built-in cameras, one on the front above the display and one on the back next to the LED flash. The front camera has been tuned for FaceTime. It has just the right field of view and focal length to focus on your face at arm’s length. So it always presents you in the best possible light.
Share what you see with the back camera.
Imagine your sister is away at school and can’t make it to your son’s birthday. So you’re cheering her up with a FaceTime call. As the cupcakes come out, your son’s eyes light up, and you just have to share it. Tap a button, and before you can say, “Make a wish,” iPhone 4 switches to the back camera, and to the birthday boy’s big moment. Another tap switches back to the front camera and to you. Simple, fast, and fun.S
Many people have reported that Chat never works for them in the iPhone app. If you try to send a message but the app says it could not be delivered, this usually means that when you were using Facebook on the web you chose to “go offline” in Chat. The problem is that the iPhone app doesn’t tell you that you’re offline, or give you the option to go online, so you’re left confused and thinking that Chat is broken.
