Apple engineers have made contact with iPhone 4S users who have complained about experiencing short battery life on the new iPhone 4S.

Some new iPhone buyers have seen a 10 per cent drop in battery life each hour, when the device is in standby mode, with Apple's guide suggesting it should last for 200 hours.


Free bumpers coming soon?

I read somewhere this is an app - probably Facebook - switching itself into a mode that causes the drain.

But then, I don't have a smart enough phone to check that.

Mine's been reasonably well behaved. Drains a tad more quickly than the 3GS but not in an inconveniencing way.

From what I have heard, it’s a corrupted contact in the address book that’s causing a failure during syncing to iCloud. All those retries, especially on 3G, are causing power drains.

I've got a 4 rather than a 4s but I'm actually finding the battery lifespan has improved slightly. A friend was having issues then he realised he'd set a lot of reminders which were GPS triggered, so the GPS was on pretty much all the time. He switched some of them off and things improved. However I have also seen web reports that suggest there are some seeing high battery use without such straightforward fixes. I've heard the same iCloud related issue as Paul mentioned.

I'm seeing worse battery usage than before I upgrade to ios5, but that could be because I've recently turned Bluetooth on permanently.

I've noticed no difference upgrading to iOS 5 on my iPhone 4. The only thing that seems to have drained my battery recently is playin Jetpack Joyride for about two hours at a time...

User tests suggest that bug in iOS 5 may be polling mobile mast data too frequently and running down battery

Blimey. A bug in a .0 release.
This must be a first.

I thought I was suffering from a slight reduction in battery capacity, but overall, it's been so slight it's not that much of a deal. A days average use (for me) still takes it down to c. 50%.
And even before 5.0, leaving the GPS on was a recipe for eating battery.

Exactly right

Non-story. Move along.

This should have been found in field trials. Oh wait they keep on losing the handsets.

The Find Friends feature is rumoured as a culprit, because it constantly uses GPS and network.

On the other hand, my boss has had 2 replacement iPhone 4 phones since May with dead batteries - one stopped charging / lasted only a couple of hours and another was DoA (the other two had faulty antennes). It looks like it could also be a quality control problem, if the 4S is having similar problems.

iOS upgrade swells iPhone battery-suckage grief

Quote:
Apple admitted battery-life problems with the iPhone 4S and the new iOS 5 earlier this month, and released the iOS 5.0.1 update on Thursday. Many users, however, report that the fix either didn't help or made matters worse.

It is a variety of apps. The Apple Contacts App is one, it keeps crashing, sending a report to Apple, restarting, crashing, sending report to Apple, restarting ad infinitum.

Other Apple apps are also causing similar problems. With the contacts, deleting all contacts and resynching can help, but not always.

Hopefully the patch this week will sort out the problem.
