Apple is aware of battery life problem on 4s and iphone 4

[p3unit32]

Though you only mentioned one post ago that you're in AirPlane mode. That changes everything! When the transmitter circuitry is disabled the battery usage goes WAAY up. It's like turning it into an iPad. That explains everything. Report back to us what your numbers are with the phone transmitter turned back on.

NdX you're on it! I believe some of these guys are toggling on airport mode and using wi-fi as you stated. I didn't think about until you mentioned it. Guys if we're getting these states using the your wireless data that's great, only show the results of using the phone without using airport mode.

I think part of my battery problem is my location. I use a microcell to amplify the 3G signal, but it works much like wi-fi. However I have discovered in good 3G areas I retain better battery usages and standby.

Yes. If people here are posting results after having been on Airplane Mode for any length of time in the usage cycle then they are skewing our results here. As I said - the chief reason an iPad gets WAAAAY better battery life than an iPhone is the phone transmitter circuitry not being in the iPad.

The title of this thread is a little misleading too in that the only battery problems are really with the iPhone 4S' and not the 4's. People posting results should really only be 4s owners with 5.0 or 5.0.1. And please indicate which iOS you're running too - 5.0 or 5.0.1 when you post results. I know some of you are waiting for a jailbreak and are staying at 5.0.

And Sekelani brings up a good point in the apparent 'inconsistency' of this problem. Though I have had better result,s than most people complaining, with my 4s on 5.0 and 5.0.1 there are days when my results are WAY better than other days given nearly the exact same usage. It leads you to believe that if there's truly no issue with the battery itself - there's an issue in the software ONLY with THINGS THAT CAN CHANGE daily.. Like location services issues tend to change depending what you've asked to know your location. I can't think of, right now off hand, other such things that can change very regularly to a higher then back to a lower drain on the CPU of the phone. This is what's taking Apple so long to find a fix.

Then the other thing that 'confounds' this process of finding the problem is that it seems about 80% of you that go exchange your phones out - get BETTER results with a new phone - leading us to believe that it CAN be about hardware and battery construction issues -- but MORE LIKELY what this shows is that -- our BACKUPS from our IPhone 4's that we're reloading INTO a 4s (initially) NOT setting it up as a new phone -- could be the problem. Maybe it's something in the way iOS 5 is dealing with some of our apps and their data - that's part of this issue too. I think it would be a very good idea for most of us who are having problems, if we haven't done so already, to do a complete wipe of our phones - and start fresh. Your game data will be gone and other apps that store data on the phone and not in the cloud. Get as much of your contact and calendar data in the cloud or backed up in iTunes. BUT ONLY RELOAD YOUR APPS from the apple store - via the DOWNLOAD PURCHASED option. This should put your phone in a completely CLEAN state and yet you'll have all your apps, contact and calendar data - which is important. I personally wouldn't restore even your email data. Set up your email accounts afresh too - and let the old emails come in from your server. This will lose you some SENT MAIL data if you don't have Exchange servers. But it's worth it - to get a CLEAN START.

The process I'm talking about will take a couple of hours and is a royal pain. But it could make a LOT of difference and then Apple's final fix will make even MORE difference for us.

Just my current thinking - as to why there's so much inconsistency in this battery usage issue.

I will be the guinea pig and leave my phone in the data state that came over from my iPhone 4. Granted my battery life isn't as bad as some but it is still way below what I expect of Apple at present.

I just checked for a Beta and still nothing posted

And I am still 100% in the camp that this is an iOS 5 issue. But I should clarify something. I believe it is caused by possibly bad data with new code in relationship with the new hardware that iOS 5 is running on. IE something is combining in a way no one could have predicted. Whether it is a polling issue with the new CDMA/GSM cell chip or the new GPU running code constantly or even something with the multi-threading in the A5 CPU, we just won't know for sure till Apple tells us.

If this theory is true, we would see bad battery life from iPad 2's with 3g. I will see what they are saying about the batt.

Untrue. The iPad 2 doesn't use the same exact GSM/CDMA cell chip, in fact they are not even close. The GPU is set up differently due to the resolution. And the A5 while in theory may be identical, odds are it has a revision/upgrade in it. So the combination of events could cause an issue that wouldn't show up at all in the iPad 2.

How are you able to upload a full size photo on this site? Everyone else's photo when you tap on it comes up 1/4 size.

I hit home and power same time.

Than upload via tappatalk

Who as tried this as I'm about to try

Hmmm. I have run benchmarks on the iPad 2 and 4S and they come out almost identical. That doesn't guarantee the A5 has not had any changes made just an observation. It makes sense about the 3g radio though.

Those benchmarks better not have come out almost identical. Because if they did you have an issue. The iPad 2 is clocked 200 Mhz higher than the iPhone 4S.

 

[Rocko]

Yeah, your right. Maybe the 200hz higher compensated for the larger strain of a larger screen/higher resolution. I will run them again this weekend and keep track of the scores.

 

[AATT]

Is this good or bad ?

 

[Rocko]

Depends on what you did for that hour. 5-6 hours of games/texting/web surfing are on par I would say.

 

[Rocko]

Here is my latest. Again, about 50% music, 20% email, 20% net 10% games. 11.5 Hours Usage, 41 hours standby. Pretty darn good. Never in airplane mode.

 

[AATT]

you got the ios 5.1 ?
do you think at how my battery is running i should install the update ?
btw for that 1 hour i played with the services downloaded some apps . phones . camera , web and siri .5 minutes of angry . and tried some applications to control my desktop

No, 5.1 is not out. I have 5.0.1. Yes, you should update.
