iOS 5.1 Battery Life is Significantly Improved
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.
