Q: iPhone 4s Battery Life?

It appears that the news of the battery life is becoming more wide spread. It has been mentioned on Yahoo under the Technology section (Pockitint). This is quite a reputable site which i always use for tech updates and news.

I landed on this post because my battery life on my 4S is horrendous.

I hate to have to turn off all the cool features that make the phone so wonderful in order to get reasonable battery life.  There's gotta be a bug in the OS that's leaving battery-sucking processes running.

The only way I found to prolongthe battery life was in settings / general / network /cellular data (disable)This prevents information from being exchanged with siteslike:push Apple,  deploy.akamaytechnologies and other ftps.(thisconsuming charge of battery)who want to use the netstat app (free in the Apple store) may verifywhat I am saying.If the "cellular data" is on, the device exchangesinformation.I find it absurd to have to shut down the exchange of datavia the cellular network on a cell phone to preventinformation unknown to be exchanged with people who donot know who they are, without my permission and also byeating up my battery for it.I look forward to a solution that is not trade my iphone fora handset of another make.

For info the iPhone 4s has just gone past 35 minutes with the new SIM card installed and it hasn't dropped 1% yet. The old SIM card would have got through 2% by now.

I don't want to get people's hopes up. I'm going to run this on for another half hour and see what happens. I'm then going to turn things back on in stages and see what happens to battery life.

Stay tuned.

I've been able to improve battery by doing two thing, both of which seem to be workarounds for bugs. First I turned off time zone location services. Next I turned off exchange calendars. This gets me to normal battery use similar to my old 4.

I agree Apple needs to fix this.

I have turned off exchange calender for google and time zone setting on my wife's iphone she is still reporting excessive drain when i spoke to her this morning though.  Also she has a regular iphone 4, not the 4s

Listen everyone.

We shouldnt have to disable or turn off ANYTHING at all! This phone should be working completly fine and last the 200 hours of standby like it was advertised to do. Obviously there is something wrong and Apple needs to send a fix for it.

I did talk to the Apple rep yesterday and he said they are checking the forums.

Everyday though, I am seeing my battery last about 1-2 hours longer with the same amout of use. I have done about 3 calibrations and they seem to work. I expect about Sunday or mid next week to be getting about 2 days of battery with moderate to heavy use. If not , then there is a problem.

I have a gut feeling the battery drainage is related to the SIM Pin issue. I posted that in several places already, but noone seems to care.

I'm inclined to agree, either that or problematic / incompatible SIM cards. My iPhone 4s made it to 52 minutes without dropping 1% on the new SIM card. The old SIM card made the phone loose 1% every 15 minutes.

Since my update to iOS 5 on Sunday, my iPhone 4S runs empty within 6 hours (from 100 to 0%!) That never happened before that. I close all the apps regurarely but during the day I need more apps to be working: GPS, facebook, wordfeud , iCal, mail, I don't even use Safari that much. Why! I read that this was an issue on the beta version. It shouldn't be in this alfa version. HELP!

I went to apple yesterday and im going back in a couple of hours today to get a new one, but i doubt it will be any better? My sim card is the same one from my iphone 4, is that a problem and last question if i go and get teh samsung galaxy s2 how does it work with apple products exp: ipad macbook pro, apple, apple tv?

iPhone 4s 32GB GSM (AT&T) black

Received mine via UPS on launch day.

settings -> general -> usage -> time since last full charge:

Usage: 2 hours 47 minutes

Standby: 4 hours 37 minutes

Combined Total: 7 hours 24 minutes (I don't know how this is possible when I unplugged it from the charger at 7:30 am, which is a little less than 5 hours ago?)

Current battery remaining: 64%

Turned off everything that isn't necessary as posted numerous times in previous posts beginning Monday. Same problems occurring as evidenced by my above statistics.

NOTE: Our household also upgraded iPhone 3GS 16GB and iPad1 wifi only 64GB to iOS5 and seeing similar battery draining problems.

In my humble opinion this is a combination of iOS5 and iCloud software issues and the fact that the A5 processor requires a heck of a lot more power than it's predecessor. Look at the dramtatic increase in battery hardware from the iPad1 to the iPad2. The original iPad had a couple of batteries that occupied about 65% of the bottom of the case. The iPad 2 has 3 batteries that occupy 100% of the bottom case. Why? Because the processor needs it!

As an earlier post notes, the battery increase from the iPhone 4 to 4S was insignificant. So why would Apple make a significant change in the iPad and not the iPhone when moving to more powerful processors? Because they needed to get a product to market and weren't ready to launch the iPhone 5 (which all reputable sources show a larger cased version to accommodate a larger battery).

Apple will most likely come out with some firmware patches that will help to resolve this issue. But no matter what device you own, if you're running iOS5 and iCloud you're going to see a reduction in battery performance. More functionality requires more power. In the case of the iPhone 4S, don't expect to run Siri and all of the other features that a smartphone is supposed to be able to run (without having to toggle things on and off all day to spare battery life) and expect a full days use out of it with the current hardware configuration.

I'll stick it out until next Thursday and if Apple can't get it right by then they'll be taking another 4S back and I'll wait for the 5. Unless Android comes up with something better.

If you are near a mobile / cell phone carriers shop. Drop in and ask them for a replacement SIM card and get them to port your number across to it. Insert that into your iPhone 4s and see if that makes it better. SIM card shouldn't cost anything. It won't do any harm trying.

the galaxy s2 is an android based phone, as far as working with it.  everything syncs over google's cloud so whatever contacts, info and so on you have tied into your google account would sync with the phone and to access your contacts and other info you would need to log into google from the browser to access it.  If your a big google user it wouldnt be too painful of a change but if u never use gmail and have no contacts assigned to it you would have to re create them in your google account.

Iphone 4s white 64GB O2 network UK.

over the last few days the battery has been draining at alarming rate, making impossible use for a normal day.

100% charge in the morning at 7am, 16% by 1pm...with a slight warming of the back glass.

No major change to the setup as I refuse to have a Sterling 380 phone crippled, I would rather return.

HOWEVER, today the battery drain was a lot better. Maybe the network has noticed something ?

Same usage for today 7am 100%, 56% by 1PM. Is this a fix in progress ?

Will return phone this weekend if this does not get either acknowledged by Apple as a problem or a fix issued.
