Q: iPhone 4s Battery Life?

Just so you know, MS won't be any better, just VASTLY slower to respond to problems.  Just switched on an iPhone from a Windows Phone.  Been there, done that.

>>  I have one more question! How many coverage bars do you have ussually thru the day?

Four.

And since I last posted my stats, my batery has dropped from 75% to 71%.

Amazing.  You paid for instant gratification?  I don't recall seeing that on the list of accessories.  How DID I miss that.  It's a good feature, but I don't think you will find that on ANY smartphone.  Tell your problems to Android 2.2.1 users who are told if they want 4.0, they can buy a new phone.  Unreasonable expectations will only make you a sad and bitter person, and won't change things at all.

If you had done the research I did before buying the phone, you would know that Apple  just doesn't ever admit to making an error, or having a problem unless it becomes so pressing that they are forced to, and then they will try to avoid admitting it was their fault.  At the same time, they DO pursue and solve problems, and make the solution available to the users without further cost.  That is pretty rare in the world today.

Your case sounds like a pretty clear-cut case of a hardware problem in the radio chip.  Contact an Apple store or your seller to get it replaced.

My 4s is showing usage of 2hours 24 mins, standby of 2days 3 hours and 45% remaining. That is with Bluetooth on and location services on for all but camera.

I did find using maps on a journey with 3g did eat a bit of battery theother evening-but for such a complex and capable device I think the battery usage is just fine.

I don't use e-mail so no push-My ipad is so much more useful for dealing with text documents.

The issue is in the antenna assemblies: the only common theme is that the battery drains rapidly whenever the phone uses any of the antennae to communicate. So far the only way to keep the battery going for 8 hours with minimal usage it to turn everything off. Why did I buy a $565 smartphone to make it as dumb as a brick?

They have built into the US iPhone the ability to communicate with CDMA on two networks (Verizon/Sprint) and GSM (AT&T). In addition, Apple has redesigned the antenna that goes all the way around the phone into TWO assemblies to boost reception and minimize dropped call complaints.It is also quite possible that though the phone is activated on only one network, the other antenna assembly is either turning on during this activation and/or it is not turning back off.

This is the issue as the new batteries are not able to match the draw of the antenna assemblies. Jobs would have never let this get out the door.

would yall consider this good battery life? I restored to 5.0.1 9A406 and it has seemed to increase my battery life

I have push off, Setting time zone off, location iads off

I took the phone off the charger at like 8 this morning with lil use and its still at 100%

I'm going with what others are saying: the dual antenna probably has a defect somewhere. I have Verizon, so CDMA, and it's possible that the GSM antenna may inadvertently be searching for a signal. At home, I can go on standby with 100% for over 10 hours via WiFi but for 3G it drops 1% every 10min or so. Living in NYC, constant searching on the subway is destructive to my battery, but I can't just turn cell off every time I go on the subway; that's ridiculous. If Apple could just come up with an antenna fix, I'm guessing the problem might start to dissipate.

Actually, I believe it is the FIRMWARE designed to manage the dual antenna, which is the problem.   How else would you explain iPhone 3 and 4 users having the same battery drain problems after upgrading to iOS5?   The question of the day is......   Can APPLE revamp the firmware to fix the battery problem without screwing up signal reception?   That's probably why we're still waiting for a fix that works.

Something that has worked for me, may work for you. Now, I did restore to 9A406 but I think what really fixed me up is this: Let the phone drain all the way till the phone shuts off itself. Then, simply recharge overnight. Doing so allowed me to get 1 day, 2 hours of standby with over 7 hours of usage. That, in my opinion, has me satisfied with this device now. Give it a try.

Actually I agree also that the dual antenna might have something to do with the battery drain beside the 3G chipset MDM6610. It might be that the iPhone 4s cannot swich efficiently between different types of antenna configurations. Anntenagate 2!?

I guess that here one refers here to firmware for the chipset MDM6610. As one may read more here:

https://discussions.apple.com/message/17183773#17183773

the chipset MDM6610 is on the "auto-pilot mode"  and the key to the auto-pilot box has been thrown into the sea. Therefore it looks like a firmware or a software cannot set the Qualcomm chipset MDM6610 on "manual-mode".

This is a more detailed description of the problem

Actually they have developed an entire subroutine burned into the chip that determines the signal available and determines when to switch. But notice I said burned into the chip. In order to change this subroutine, or to add a manual feature to it, you would have to burn an entire new chip and install it in your iPhone. So to change this on existing phones Apple would have to have Qualcomm develop the new chip and build all new iPhone 4s to replace the one you have now. I don't see that happening. Maybe with the iPhone 5 but then again that one will probably also be an LTE phone bringing in even more factors.

I am skipping answering this.

Tell your problems to Android 2.2.1 users who are told if they want 4.0, they can buy a new phone. 

I told my problems to Android 2.2.1 users and they have more or less the same battery life like me with a phone which is much cheper than mine. Also they have all the settings on all the time while mine are most of the time off!!!

If you had done the research I did before buying the phone,

I did my research and I knew that there are some issues with iPhone 4s but I thought that looking to the past Apple will fix the issue in matters of weeks. Apple fixed the antenna issue in 22 days for iPhone 4. I didn't expect that when I bought the iPhone 4 that the issues will not be fixed even next year!!! Anyway I have learned a lesson and from now on I will never buy Apple products and I will never ever recommend to anyone to buy Apple products!

At the same time, they DO pursue and solve problems, and make the solution available to the users without further cost.

Ok. I am still waiting the issues of my iPhone 4S to be fixed since last year!

That is pretty rare in the world today.

You are right! It is pretty rare that a big and famous company like Apple releases such an expensive phone with so many issues!

I may have some news for everyone.

I bought the iPhone 4s when it came out and immediately noticed a big battery life problem... Followed all the advice on the forums but nothing would really work.

I went to see the Apple store yesterday and spoke to a Genius. He told me to turn off the localization settings; but most importantly, I bought a dev account (through a website) and downloaded the beta of ios5.1 and I have to say that since then the battery life has drastically improved;

I am not saying that the issue is totally solved but only that there's hope. Battery drains faster than on my previous phone (3GS) but still a lot slower than under 5.0.1... At least I am not losing 5% in 20min of standby any more...

So let's just hope that it will actually be solved and that the final version of 5.1 will work for everyone.

What does your usage consist of?
