iOS 5.1 Battery Life is Significantly Improved Posted: 10 Mar 2012 02:13 PM PST Battery life has been an ongoing issue for some iOS 5 users, particularly those with iPhone 4 and iPhone 4S. The recent iOS 5.1 update aimed to fix that with “improved battery life” mentioned in the release notes, but just how improved is it? With casual use since the update was released, the consensus at OSXDaily suggests the improvement is substantial, and thus if you haven’t updated your iPhone, iPad, or iPod touch to iOS 5.1 yet, it is highly recommended to do so now. Every user is going to notice different gains depending on their device usage and general battery health, but overall the improvements seem to be most noticeable on cellular iOS devices, particularly iPhone 4S, iPhone 4, and iPad 2 3G models. The assumption is that some of the potential location services issues has been resolved, though its certainly worth mentioning that users of the standard Wi-Fi models and iPod touch also report a nice boost, even if it doesn’t seem to be quite as dramatic (likewise, the original drain problem usually wasn’t as bad either). Monitoring Your iOS Device Battery Life To get a good feel for the improvement and to monitor battery drain, it’s best to have made note of the prior usage history and then compare it to the iOS 5.1 battery usage, but those who have already updated won’t be able to do this obviously. Nonetheless, it also helps to turn on the “Battery Percentage” indicator and make a mental note of usage data too. Here’s how to do both of these in iOS: Tap on “Settings” and tap “General” Tap “Usage” and then swipe down to “Time since last full charge” to find the usage time (actively using the device) and standby time (device is on, but not in use) In the same “Usage” screen, swipe “Battery Percentage” to “ON” to follow precise drain The percentage indicator displays alongside the battery icon in the upper right corner of the screen: Update iOS, Calibrate the Battery, and More Update to iOS 5.1 and hopefully any lingering battery drain problems will be resolved once and for all. Don’t forget to calibrate an iOS devices battery about once a month by letting it charge to 100% and then running it down to 0% before recharging again, that helps keep the battery in good health. It’s also a good idea to disable battery draining services you don’t use often, be it Bluetooth or Push Notifications, and you can check out some general iOS 5 battery life tips we have discussed before for more on that. On a side note, if you’re unable to download and update iOS 5.1 try the DNS change we discussed recently, it should resolve that problem immediately and allow you to update without the network errors. Did iOS 5.1 help your iPhone and iPad battery life too? Let us know in the comments.

Maintain File Ownership & Permissions When Copying With Duplicate Exactly in OS X Posted: 10 Mar 2012 12:20 PM PST Mac OS X 10.7 and OS X 10.8 include a nice new ability to be able to duplicate and paste files exactly. Basically this means that if a file is owned by another user, Duplicate Exactly and Paste Exactly will preserve the files original ownership and permissions, rather than copy the file with the current user becoming the new owner. Duplicate Exactly Select a file or folder within the Finder and hit Command+Option+Shift+D to perform an exact duplication. You will be presented with a window to authenticate the copy to allow the ownership state to maintain consistency. The duplicate will be placed alongside the original, maintaining ownership integrity. Paste Exactly Similarly, there is also a new feature that lets you Paste Exactly, maintaining the same ownership and permissions when using cut and paste in the OS X Finder. This is activated with Command+Shift+Option+V after a file or folder has already been placed in the clipboard buffer. These two tips are geared for more advanced users and administrators who are altering another users files or directories. Try them out the next time you are editing another users files and save yourself a potential headache.

Mac Setup: MacBook Pro 13″ iOS & Web Development Workstation Posted: 10 Mar 2012 11:53 AM PST This weeks Mac setup comes to us from Raphael C, who uses his Apple gear for iOS and web development. It’s a fairly simple setup, which is perfect for getting things done without too many distractions. Here’s the hardware in use: Macbook Pro 13″ mid-2011 model Samsung 22″ T220 Display Apple Wireless Keyboard Magic Trackpad iPad 2 16GB with 3G iPhone 4S iPhone 3G Raphael points out that the iPhone 3G is mostly around for nostalgia, although it probably continues to have use for testing purposes. This is a great setup that closely resembles my own, and if you frequent our weekend Mac setups posts, you’ll notice a strong trend of laptop based workstations, where the primary machine is a MacBook Pro or MacBook Air connected to an external display and a keyboard and mouse. Other than the obvious portability aspect, the major advantage to using a Mac laptop is the ease of which a dual-screen setup is immediately possible just by connecting an external display. Maybe it’s just our readers who are inclined to do this, but speaking from experience, it’s a great way to boost productivity. Send in pictures of your own Apple & Mac hardware setups! Email to osxdailycom@gmail.com and include some brief details of the hardware and what it’s used for.
