Show battery percentage on your iPhone

iPhones show a battery meter at the top right of the screen, that shows you how much charge is remaining. You can also make that meter show an actual percentage of remaining charge, which lets you know more precisely when it's time to juice up again.

To show the battery percentage on your iPhone, tap on the "Settings" app (usually on your main home screen) and then tap "General".

Next tap "Usage" (I know - not very intuitive, but it's in there).

You can toggle "Battery Percentage" from Off to On just by tapping "Off".


That's all there is to it, but knowing where to tap is the key, and in this case it took a bit of tapping around to find it. Hope this is helpful :-)

Transfer iPhone Voice Memos to Your Computer

The iPhone's built-in Voice Memos app has been a useful addition ever since it was bundled with iPhone OS 3.0. It lets you record audio snippets and play them back later, and you can send them to yourself or others using the built-in email sharing feature.

It's not entirely clear how to use the Voice Memos app though, or how to send a voice recording to someone via email - let alone figure out how to transfer a voice recording to your computer.

Here are the steps for 1) recording audio with the Voice Memos app on your iPhone, 2) sharing those audio snippets using email, and 3) transferring those audio files to your computer:

1. Record audio with the Voice Memos iPhone app:

Open the Voice Memos app on your iPhone and tap the button on the left to start recording. You can talk into the microphone or place it near what you're trying to record.

Tap the button on the bottom right to stop recording, and tap it again to see a list of voice memos that you've recorded.

2. Share recorded audio clips using email:

Tap the arrow next to each audio clip to view options for sharing that clip.

Tap the "Share" button and select "Email" to send the audio clip as an email to yourself or someone else.

3. Transfer recorded audio clips to your computer:

If you have a large audio recording, you won't be able to share it using email. For example, the audio clip I recorded above was for over 50 minutes and was about 24 MB in size - far too large for email, and my iPhone wouldn't let me send it.

In this case, when the audio file is too large to share using email, then you'll need to transfer the audio file to your computer using iTunes.

Share Your MacBook's Internet Connection with Your iPhone or iPad

Some hotels are greedy and charge for internet connectivity, or even worse they limit internet to a single wired connection per room - like the hotel I'm staying in right now. They only have a single Ethernet cable in the room and no WiFi.

Fortunately I'm using a MacbookPro which makes it's fairly easy to share the internet connection with my iPhone and iPad. Just turn on Internet Sharing and the built-in Airport will act like a wireless access point that you can connect to from any wireless device, just like you would connect to your wireless home network.

Here's the step-by-step:

1. Make sure an Ethernet cable is plugged into your Mac and you can browse the web.

2. Make sure your Airport is also turned on, by clicking the wireless icon in your menu bar and selecting "Turn Airport On".

3. Open System Preferences (click the Apple icon on the menu bar and you'll see it as a menu option) and select "Sharing".

4. Click "Internet Sharing" and make sure "Ethernet" is selected in the "Share your connection from" dropdown, and "Airport" is selected in the "To computers using" listbox.

5. Click "Internet Sharing" one more time and you'll be asked if you're sure you want to turn on Internet Sharing. Click "Start" to turn it on and start sharing your internet connection with your iPhone or iPad.

That's all it takes to share your Mac's internet connection and then you'll be able to connect your iPad or iPhone to it the same way you'd connect to any other wireless network.

Transfer purchased apps and music from your iPhone 3G/3GS to your new iPhone 4

So you're a proud owner of a new iPhone 4 - maybe you were even in the same line I just stood in to get mine this morning.

But now you realize you have a considerable investment in apps and music sitting on your old iPhone 3G or 3GS, and don't know how to transfer them over to your new iPhone.

The trick is to first backup your old phone to iTunes, and then you can restore this backup to your new iPhone, which will transfer everything over.

Here's how to transfer purchased apps and songs from your iPhone 3G/3GS to your new iPhone 4 in 5 easy steps:

1. Connect your old iPhone to your computer and open iTunes.

2. Transfer your purchases by right-clicking your iPhone in iTunes and selecting "Transfer Purchases" from the shortcut menu.

You'll see iTunes transferring your apps and songs from your old iPhone to your computer:

3. Backup your old iPhone.

Right-click on your iPhone again in iTunes and select "Back Up" from the shortcut menu.

4. Connect your new iPhone 4 (after disconnecting the old one of course).

5. Restore your iPhone 4 using the old iPhone's backup.

Right-click again on your iPhone 4 in iTunes and select "Restore from Backup".

Choose the backup you created in the 3rd step above:

Click "Restore" and wait for iTunes to restore from the backup (which also transfers over your purchased apps and music):
