      ✔ Silent/Ring switch: The switch above the volume buttons is a mute button. Push it to the back and you see a red bar. This is the off or silent position. Pushed to the front is the on or ring position. When iPhone is in silent mode, it vibrates when calls or alerts come in. If your iPhone rings and you prefer not to answer, you can turn the Silent/Ring switch off. Your caller continues to hear the phone ring until he decides to hang up or leave a voicemail message, but your iPhone will be silent although it will continue to vibrate. See Book II, Chapter 1 for information about declining calls.

      

When iPhone is in silent mode, alarms you set are still audible, which means you can put your iPhone in silent mode when you go to sleep but you’ll hear the alarm you set to wake you in the morning. The audio for Music and some games will be heard through the speaker or earphones, if you happen to have those plugged into your iPhone (and into your ears, of course).

Charging Your iPhone Battery

      Like all battery-powered gadgets, your iPhone is useless with an uncharged battery. The good news is that iPhone recharges in less than an hour, and you can charge the battery in several ways, which we describe here. Even though it recharges quickly, sometimes you want to conserve that charge for as long as possible; check out the sidebar at the end of this section for tips on helping your iPhone hold the battery charge longer.

       Plugging into the USB charger

      Your iPhone comes with a USB connection cable and a USB power adapter. To charge the battery, plug the dock connector into the dock port at the base of your iPhone, plug the USB end into the USB power adapter and plug the power adapter into an electrical outlet. iPhone beeps, which lets you know it’s actively charging.

      

The power adapter automatically adjusts to 110 or 220 voltage, based on the voltage for the location you’re plugging into. If you’re using your iPhone outside the United States, you have to purchase an adapter that changes the plug conformation to meet the outlet style of the country you’re visiting. You can find a kit at the Apple Store (http://store.apple.com/us) or single adapters at TravelProducts.com (www.travelproducts.com). If you use a MacBook, PlugBug World from Twelve South (www.twelvesouth.com) connects to the Mac’s power block and houses a USB port so you can charge your Mac and iPhone on the same outlet. Or you can charge your iPhone with your computer’s USB port, as we explain next.

       Charging with your Mac or PC’s USB port

      When you connect your iPhone to a USB port on your computer to sync or transfer photos, the battery automatically begins taking a charge. Again, iPhone beeps, which lets you know this is going on.

      

If your computer is turned off or is sleeping, your iPhone battery may drain instead of charge, so make sure your computer is on whenever you connect your iPhone to it.

      Although plugging your iPhone into any recent or new Mac can charge your iPhone, the same isn’t necessarily true for recent or new Windows desktop and laptop computers or older Macs. Apple explains that’s because the USB ports on certain models don’t pass through enough wattage to charge your iPhone. If connecting your iPhone to your USB port doesn’t yield a charge – you know it’s charging because it beeps and there’s a lightning bolt next to the battery in the Status bar – try plugging into a port dock on a powered USB hub. If that doesn’t work, you’ll have to plug into a charger to charge your iPhone.

      

Don’t pull the cable to detach your iPhone from your computer. Always grasp the hard, square part of either end of the USB cable to remove it.

      If iPhone’s battery charge drops very low or runs down completely, your iPhone automatically shuts itself off. To bring your iPhone back to life, you must attach the USB cable to a power source (your computer or an electrical outlet). When your iPhone shuts itself off because the battery charge is too low or nearly empty, you won’t be able to use your iPhone until the battery reaches a minimal charge level. Usually you only have to wait a few minutes before your iPhone turns itself on again.

      

To preserve the overall life, you should cycle the battery on a monthly basis. Cycling is letting the battery completely discharge and then charging it fully.

       More charging options

      Apple and other third-party vendors make charging accessories. You can use an iPhone dock, which is a type of base that you set your iPhone in to charge the battery – it’s convenient to have on your desk to keep your iPhone close at hand. Make sure you purchase the dock that’s appropriate for the iPhone model you use. You can also purchase battery packs that attach to your iPhone to get a longer charge. And, if you spend a lot of time in your car, another option is a USB adapter that plugs into the cigarette lighter to charge your iPhone. Many newer car models come with a built-in USB port that both charges your iPhone and lets you listen to audio from your iPhone through the car’s stereo speakers.

      You can replace standard electrical outlets with USB-enabled outlets, so all you have to do is plug in the cable. We’ve seen USB outlets more frequently in hotels and airplanes, too, which makes charging while traveling super easy. If charging in a hotel room, make sure the USB outlet still works when you turn out the lights.

       Keeping an eye on your charges

      The battery icon in the Status bar indicates roughly how much battery power you have. If you want to see a specific percentage, open the Settings app, tap General, tap Usage, and tap the Battery Percentage switch on.

      You can see detailed battery charge consumption in the Settings app by tapping General, tapping Usage, and tapping Battery Usage. The screen shown in Figure 2-2 opens. You see how much time has passed since your last charge, specified in two ways:

      ✔ Usage: How much you’ve used it

      ✔ Standby: How much time your iPhone spent sleeping

      The list shows which apps have been the top battery consumers in the last 24 hours. As in Figure 2-2, low (cellular data) signal is the cause for a high usage of apps that use the Internet like Facebook and Mail.

      Figure 2-2: Battery Usage shows which apps are power hogs.

       Changing the battery

      If you keep your iPhone for many years, sooner or later, you’ll need to replace the battery. Despite our do-it-yourself (DIY) world, you can’t replace the battery yourself. You have to send it in to the Battery Replacement Program. For $85 (as of this writing), you send your iPhone to Apple or take it to an Apple Store, the battery СКАЧАТЬ
