iPhone 4s Battery Life?

I lost 20% on my 4 overnight. I wonder if it has something to do with the wireless sync.

Support was willing to send me a new phone, I am keeping the case open for a few days to see if there is an acknowledgement and/or forthcoming update. I'd rather not have ot start over with a new phone.

Has anyone figured anythiing out yet? I did a full w/trickle charge last night to 100% Today I used the phone maybe 1/2 hour or 45 minutes and I am down to 35% charge. On my iPhone 4 I would charge every few days. Seems with the iPhone 4s I will have to charge it every night or more.

I have to charge at least 1x a day mid-day; I'd be thrilled to only charge at night again.

I've also definitely noticed worst battery life on the 4S in comparisson to my 15 month old iPhone 4.

In addition, it takes 2hrs straight to charge the 4S from 0-100%. My iPhone 4 used to take around 1hr to fully charge. Slightly disappointed about this.

Experiencing the same problem. What is the best solution? Cheers.

I found a lot of issues in settings, things turned on, fetch turned on, too much in location services, turned PING off in settings, and more. Also people have been saying there is an iCloud / MobileMe issue and to turn off each item individual, reset the phone, then turn them back on one by one. Also seems in some of the emails sync of calendar and notes are turned on, so I turned them off as well.

Doing a full charge / top off with Battery Magic and will test again tomorrow.

I'm relieved to see that so many other people are having major battery issues as well. I lost 23% in about thirty minutes this morning -- using the regular NOTES app! I wasn't surfing the web, playing games, or anything like that. Just typing in the Notes app.

• Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)
• Standby time: Up to 200 hours
• Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi
• Video playback: Up to 10 hours
• Audio playback: Up to 40 hours

Im having all the same problems as you guys, losing 3-5% every ten minutes on light usage so i rang apple and they have gotten me to restore it and do some tests and if it's still bad they're going to give me a new one

Legitimate name **** up...

for now

I just found another thing that might be draining the battery... Diagnostics & Usage...

It was set to Automatically Send(don;t remember if I agreed to that or it is the default) but the shocking part is if you look in the 'Diagnostic & Usage Data' you will find many, many sends per day...on mine, about 30 per day...

I changed it to 'Don't Send' and will see if that helps...

I'm worried about my battery life as well... It was a huge investment for me to upgrade from the 3GS to the 4S and for example, I fully charged the battery overnight, woke up and took the phone off the charger to go to work at about 8:45 a.m. it's 10:40 a.m now, I have not used the phone at all and it's gone from 100% to 87% without using it... My 3GS battery life was even better than this.

I read somewhere that the battery "comes to life" after a few drains and recharges. I sure hope that's right...

rpitsnogle is right, I also found under 'Diagnostic & Usage Data' about 300 sends to Apple in a 3-day period, so I also turned that off to see if it makes a difference.

My battery is draining quicker than I expected as well. I did hear that the Siri "Raise to speak" feature causes additional battery drainage as well due to monitoring the accelerometer. This is unconfirmed but I'm going to try turning that of today for troubleshooting.

Same here....came visiting the forum here to see if anyone else was noticing significant battery issues. Glad to hear I'm not the only one - looking forward to a solution.

Cheers
