The original iPhone 4 stumbled out of the gate with an infamous antenna issue that left many users very disappointed. And while the problem was eventually resolved in a modified housing that carried forward to the recently released iPhone 4S, the latest model seems to be suffering from its own serious performance issues.
Battery life. Whether or not it's fixable with a software patch, special trick or voodoo incantation, one thing is for sure: It's a problem.
In a thread titled "iPhone 4s Battery Life?" on Apple's official support forums, there are already thousands of posts with unofficial test results and theories as to why the iPhone 4S's battery life isn't up to snuff. And there are more than 100,000 views from users trying to find an answer. It seems like not even Apple knows what's going on just yet.
A couple of days ago we reported on a story in The Guardian that Apple's senior engineers had been contacting users complaining about battery life issues. One user in particular had found their iPhone 4S battery draining in excess of 10 per cent every hour, even when in standby mode with features like Siri and location services completely deactivated. And after asking them detailed questions about their usage, an Apple engineer had them sync and install a special file that would presumably provide more details about the problem.
But at the moment there is no official solution, no definitive answer, and no word from Apple as to why it's happening — or when a fix might be on the way. Just speculation as to what might be the cause and reports on how bad it is. Over in the MacRumors forums, one user reported a dead phone four hours after going to sleep with at least 60 per cent battery life remaining.
Went to bed last night around 1130 PM with 60 per cent battery life. Closed all open apps. Got up around 330 AM for a restroom run and noticed my phone was dead. That's scary because my iPhone is my alarm clock! I am on the phone all the time - even so the iPhone 4 yielded twice the usage as I'm getting now with my iPhone 4S. It's a great phone, but this battery issue is a pain!
So if it's not an issue with a specific app, maybe the problem lies with how the iPhone 4S is reporting or detecting its current charge levels? In another post on the MacRumors forum, a user managed to resolve their battery life issues by simply draining their 4S all the way until it powered down, then charging it back up to 100 percent:
1) Drain the battery until the phone shuts off on its own. 2) Charge it non-stop back to 100 per cent (Should take 2 - 3 hrs)
When I first started draining the phone, I was losing about 5-7 per cent per hour in standby. As the battery drained, the rate the percentage was dropping got slower and when it got to 1 per cent, it sat there for almost an hour. Then it finally shut itself off. I recharged back to 100 per cent in one sitting, and now it's got the same or better battery life my 3GS had that I was upgrading from.
So we know there are plenty of you who've already upgraded to the iPhone 4S and have had the chance to spend a couple of weeks with it. Do you have any tricks? Horror stories? Let us know in the comments.
