re: 4 Fixes For iPhone 4S Battery Woes
Like so many other consumers have reported, I experienced an alarmingly rapid battery depletion on my brand new iPhone 4S. It was quite a relief to finally identify and rectify the problem. I didn't have to disable valuable phone features, delete/recreate email accounts, drain my battery completely, or perform a hard reset. In my case, the solution was actually quite easy and painless.

While there have multiple causes and solutions reported, issues related to Location Services seem to be the most common culprits of the accelerated battery drain problem. I've seen many reports specifically about the Time Zone function being the cause, but it was something a little different in my case. And while the specific cause may be slightly different in your case as well, the following information may help you to easily identify what that is.

If you don't already have the location services icon turned on, I would strongly encourage you to do that by going into Settings -+ Location Services -+ scroll to the bottom -+ System Services -+ scroll to the bottom -+ enable Status Bar Icon. You can see a sample of the icon in the image to the right. With the Status Bar Icon enabled, you should see the purple icon momentarily appear between the time and the Bluetooth icon at the top of the screen whenever an app is identifying your location. You will know there is a problem if you see that the icon is remaining there. In that case, you'll want to go into Settings and locate the offending app in Location Services. This is precisely how I identified the problem on my iPhone.

In my case, when I went to location services under settings, it was apparent that the offending app was actually Siri (although the status icon appears gray in the image to the right, it was stuck in purple when I discovered the problem). I powered-cycled my iPhone thinking that would clear it up, but surprisingly it didn't. So I reluctantly proceeded to turn location services off for Siri. It was clearly hung up for some reason, which would understandably cause a serious drain. I could practically hear my battery release a great sigh of relief while I immediately saw a substantial improvement in power conservation. Hoping that I wasn't going to have to live with that setting disabled, I later held my breath and turned the setting back on. Thankfully, the battery life has been great for several days straight.

It seems quite possible to me that any of the LS-enabled apps might cause this sort of hang, so don't limit your attention to Siri or the Time Zone setting.

This may actually be an iOS5 issue rather than just an iPhone 4S issue. It's been reported on iPhone 3GS devices running iOS5 too.

re: 4 Fixes For iPhone 4S Battery Woes
I don't assume that only 2,400 people claim to have this problem, but this was the number provided in the column. However, to account for the 'patient' people like you, let's look at that number with a smaller sample size of only 4S phones, not taking into account the 4. Reports show that over 4M people have purchased the 4S. If we take a 1% sample of that number, or 40,000, we are still looking at only 6% of people who are having issues, doesn't seem so bad now does it. They added new features with iOS 5, they require additional battery power, it should have been expected.

re: 4 Fixes For iPhone 4S Battery Woes
I can assure you that this isn't a false perception of new users, as DenverNick and others have suggested. My iPhone 4S is my third iPhone (preceded by a 3GS and a 4) and the problem is very real. No offense intended, but just because it isn't happening across the board (or happening to you) certainly doesn't mean it's imaginary or should be so readily dismissed. There was no way my phone's charge would get me though a full day before I found and fixed the problem. Now my charge holds as well as I would expect it to - I generally have 50% or so left at the end of the day. There seems to be various causes and solutions, but it was a pretty easy fix in my case and required no compromise in functionality. Perhaps my tips will work for others. I've provided full details in my blog:

re: 4 Fixes For iPhone 4S Battery Woes
I use a battery that charges my iPhone3 three times before I have to recharge the battery through a USB port. I bought it through www.poweranywhere.com.au. It also recharges my nokia phone I use for overseas, my golf GPS, and it has connectors for just about every
phone and expandable cord. Great convenience.

re: 4 Fixes For iPhone 4S Battery Woes
I am among about 15 people I know personally who haven't complained on the Apple Forum but who have severe iPhone 4 battery drains with iOS 5; we're mostly bricking the phone until the fixes are done, which will inevitably happen if Apple has any sense. All of us have had our iPhones for years, by the way. Before I turned everything that matters "off", iOS 5 was giving me 7-9 hours combined usage/standby, which is insane. With everything "off" I am now getting a total of 30-40 hours of standby/usage, which is better but only about 1/3 of what I got for the year that I have had this version before the iOS 5 update. Doesn't Apple claim 300 hours of standby alone for the iPhone 4 and 200 for the 4s? It's clearly not affecting everyone, but don't assume it's only affecting 2400 people. The quiet ones are just a bit more patient.

Why was my comment taken down? Are you not allowed to post your own opinion on this site? First visit to the site, probably the last.

re: 4 Fixes For iPhone 4S Battery Woes
Those all seem like typical ideas to save a batteries life anyway. If the software is set to check location often, or other "bugs" like that, then that is what the software is set to. If you turn it off, it would obviously save battery life. But then you are doing it at the cost of features which many may not want to do. I, for one, have noticed no difference going from my iPhone 4 running iOS 4, to now using my iPhone 4S running iOS 5. And 2,400 complaints since iOS 5 came out is not that many. I am guessing that you could attribute that to new users on Sprint and the iPhone market in general, who are switching from a "dumb" phone, to a smartphone and not understanding that they are doing so at the cost of battery life. It's hard to go from charging a phone every 3 days or so, to charging a phone every night. I would complain too.

How about carry a spare battery or by another phone. :-)
