After getting involved with the usage of iOS 5, the one issue I came across was the Battery Life for my iPhone 4 and iPhone 4S. In the update of iOS 5.1 released it was mentioned this issue will be resolved. I would recommend that if you are a casual user, and if you haven’t updated your iPhone, iPad, or iPod touch to iOS 5.1 yet, it is highly recommended to do so now.

The battery usage experience is related the way of usage which differs from user to user, but every user is going to notice different gains, but 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 it’s certainly worth mentioning that users of the standard Wi-Fi models and iPod touch also report a nice boost.

So get an idea if there is any improvement or drain of the battery life, try to record of previous usage history and then after coming on iOS 5.1 compare the performance. 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:

I believe that if you update to iOS 5.1 then battery drain problems will be resolved for many 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.

Do share with me about your experiences.
