Who else has a 4S that is just draining your battery?

 

If you update to firmware 5.0.1 it has better battery performance

 

Mine was bad for the first few days but got better after a few power cycles. I also make sure I close any apps I'm not using.

 

I have the most recent firmware. I'm not the best at closing apps but I've been trying to recently. Doesn't seem to help. It's pretty annoying how fast this charge dies! Luckily I have a 2nd iPhone.

 

Do you have Siri turned on? I disabled Siri and that iTunes ping thing and it's been a lot better.

 

By closing apps do you mean going into multitasking and deleting the apps from there or turn off wi-fi or bluetooth brightness when they aren't being used.

 

Apparently, you can get the battery boost magic app that can extend the life of your iPhone. Currently don't have it, but it has gotten good reviews.

If you don't want to spend a buck, you can turn your iPhone on airplane mode, which turns off your 3G/wifi. It can be accessed in settings. I use it a lot for skiing, since the slopes don't have any service access.

 

You can always look into a Mophie case. That's what I have and it works great as a secondary battery. This way you don't need to use another phone. Just make sure that you're not charging your battery until it's completely dead. This usually is the best way to keep the battery performance at it's peak.

 

I've had mind for about about 16 months (my 4G) and am just now noticing the batter is wearing down quicker.

 

This is the best way to kill your iPhone battery. Lithium polymer/ion batteries do not like to go below 20% very often. Making sure that you don't let your battery get too low too often is actually the best way to keep it healthy.

That said, regardless of what you do your iPhone battery life isn't going to be very good if you use the phone heavily, just the nature of the beast really.
