iPhone: 2.2 Upgrade Reduces Battery Life

It’s been quite awhile since I have posted much on Ashley’s original first generation 8GB iPhone. For her it has been a reliable, high quality all-in-one device that handles all of her daily jobs with relative ease. While she is starting to struggle a little with space management constraints, the iPhone has really been everything that she expected it to be.

Ashley’s iPhone is still “stock” so to say, meaning that it has not had a “jailbreak” performed on it – and there are a few programs from the Apple App store. Nothing really heavy, mainly email, iPod, and phone usage.

As part of keeping up to date, we have also performed the software upgrades each and every time they become available from Apple. Each update has been relatively good for the phone, whether it was 1.2, the famous 2.0, or even 2.1 updates to the iPhone software.

Recently, we upgraded to the 2.2 version of the software and the battery life has gone through the floor. When fully charged, Ashley’s first gen iPhone could last up to 5-6 days without needing to be charged. Now since the upgrade, she is lucky to get 2 days without docking or charging the phone via the USB or car charger.

At first, we thought it might have been just a change in the usage patterns of the device. But here, 4 weeks later we have changed our minds. Since no new applications have been added and the usage has not changed – we are convinced that *something* in the iPhone 2.2 software is causing the issue. Constantly being nagged by the low battery 20% warning and dismissing it was becoming a nuisance.

What could it be?

After doing a little bit of research, I have come to find out a couple of possible solutions that might apply that others have found.

Here they are:

1. Microsoft Exchange for Contacts / Calendar / Email. If you are using a Microsoft Exchange based email that leverages the Exchange ActiveSync technology to download and sync you calendar, contacts, or email. It could be the issue – apparently something in the upgrade can either corrupt or change the usage patterns of an already setup profile. In this case, simply delete the Microsoft ActiveSync profile and then re-add it.
2. Reset and erase all data on your iPhone. Some data or configurations could have become corrupted. Erase all the content, applications, and settings on your phone and then reconfigure them. To do this, go to General --> Reset --> Erase All Content and Settings.

Over the next couple of days we are going to try #1 first and then if that is not successful, try out #2. With luck, hopefully Ashley’s iPhone will go back to normal battery usage.

Is anyone else experiencing similar symptoms? If so, what did you find? Let me know with a comment!
