Q: iPhone 4s Battery Life?

It was only 80% of iPhones were bad a few weeks ago now apparently its "over 80%" of 37,000,000 are faulty. enx23 was a Qualcomm engineer and is currently Apple engineer and and has inside knowledge of its design in case you were unaware.

Not quite sure yet why he has not returned his device for refund or exchange yet since both a refund will get him free of iPhone woes completely and apparently an exchange has new chip that will resolve the static,battery whatever other issues.

Yes, the faulty component is the Qualcomm chipset MDM6610 which produces the arcing and also is responsible for the 3G network and GSM/UMTS/CDMA networks.

 

You suggest Apple has started replacing this faulty part with another in recently shipped iPhone 4S?

I have my previous phone, iPhone 4, stolen and I am in the process of ordering a 4s.

Do you mean that you post things like "4-5 battery life battery for  iPhone 4s is fine" without owning/having an iPhone 4s?????????

I have not heard anything about battery life of 4ses being abnormally short.

Yes, you have because you posted here on this forum multiple times! This forum has over one million view and over ten thousands replies so obiously the battery life issue of iPhone 4s is real and it looks like the vast majority of iphone 4s are affected by it!

Though I prefer to actually USE the phone, and use it a lot while away from the outlet, so for me an extra battery is A MUST.

Good for you!

By all my friends with Androids complain about the same. Short battery life is the plague of all modern smartphones, Apple's no exception.

Many of Android phones have short battery life but they are closer to their specifications and also they are cheaper than iPhone 4s. With iPhone 4s one gets a miserable battery life which is far away from specification and also the phone is super expensive => it is a very bad deal!

I suggest that you postpone your iPhone 4s buying until the issues of iPhone 4s are officially fixed and acknowledged!

To All,

Reset all network settings and make a hard reset and see if that helps. It did to me.

Regards.

This fix does not work!

By the way, have you checked your iPhone 4s for the static noise issue? I bet that you are affected by it and most likely is that you are not aware of it! Over 80% of iPhone 4s are affected by the static noise issue

TEST FOR STATIC NOISE ISSUE which affects >80% of iPhone 4s:

1) go in a quiet room,

2) turn off WIFI,

3) turn on the Cellular Data

4) load in Safari a large web-page (or do a speed test on your 3G network with SPEEDTEST app <http://itunes.apple.com/us/app/speedtest.net-mobile-speed/id300704847?mt=8>),

5) while you are loading the web-page or doing the Speedtest put your ear to the back of your iPhone 4s where is the Apple logo and listen carefully.

6) if you hear some noise then you are affected by the static noise issue

Another day passed, here are my stats with 5.0.1 (9A406):

Standby: 2 days

Usage: 3h 11m

Battery remaning 12%

Yesterday I did some intesive half a hour excercise of Mail, other than that, just tool/received few calls over VoIP, VoIP connected all the time over 3G. Used WiFi from time to time. My VoIP setup is not fully optimized, it could be made better, but I wanted to test the defaults.

I believe under this usage my phone will stay MUCH longer with iOS 5.1 when I am able to disable 3G data.

By the way, the purpose of this test was to verify if 9A406 improved the standby time, because before that the phone was wasting battery while doing nothing. So far I am considering this performance good. It may be coniscidence with resetting the phone, but there is a new baseband software in 9A406, so that might help as well.

To enx23: I have not exchanged my iPhone, by the way, same faulty hardware, just slightly improved software. Waiting for much improved software in 5.1.

Hello again,

i posted 2 days ago about our shared problem, the battery issue, at night i used to have more than 20% drain (6 to 7 hours)

i did it this way:

1- No icloud sync ( i deleted all the icloud)

2- emails set to Fetch instead of Push

3- NEVER set wifi sync between iTunes and phone ( this is the option you should NEVER check on iTunes under Summary menu----->Options UNCHECK Sync this Iphone with iTunes!!!!!) this is the only thing i realized by myself and not read it anywhere else, so please if you try it and works, let me know

4- Location services OFF

5- Siri Raise to Speak oFF

6- Bluetooth OFF and ON when in car only

7- I did Reset Network and deleted mails, then reinstalled mails to fetch

Finally i'm trying the push 3 emails i have

and this really was like"magic" maybe?

well over 7 hours of connected wifi at night, battery drain just 3%

and overall battery drain really was acceptable since i have arround 5 hours of usage, phoe calls viber calls, whatsapp messaging, email fetching, games Mortal Combat and Water, listened about 20 minutes of music over youtube...

So really you have to just try all these, i bet you will end up with an acceptable battery life.

Hope i could help and ready to answer anyone

Cheers

I believe under this usage my phone will stay MUCH longer with iOS 5.1 when I am able to disable 3G data.

Here is some history of iOS 5:

1) iOS 5.0 beta => battery life issue not fixed

2) iOS 5.0 => battery life issue not fixed

3) iOS 5.0.1 beta => battery life issue not fixed

4) iOS 5.0.1 build 1 => battery life issue not fixed

5) iOS 5.0.1 build 2 => battery life issue not fixed

6) iOS 5.1 beta 1 => battery life issue not fixed

7) iOS 5.1 beta 2 => battery life issue not fixed

8) iOS 5.1 beta 3 => battery life issue not fixed

How many more iOS 5 updates/releases/betas one needs to realise that the battery life issue cannot be fixed with iOS updates?

So after few hours of doing this you conclude that you fix the battery life issue of iPhone 4s. Right?

It would be great if one could post this after few days and not few hours because it is known that the battery life issue of iPhone 4s comes back again and again!

I don't know about you, but my iPhone 4S came with iOS 5.0.1(9A405). The battery life was not that bad, except it was apparently doind something in background that it was not supposed to do. Perhaps related to your beloved 3G chip.

I did network reset that actually improved things noticeably. It just coinscided that I discovered that iTunes will load build 9A406 of 5.0.1 on the iPhone 4S, when 'restored', so I opted for this -- earlied in the thread already explained why.

So for me, it was just one software -- what came with the device when purchased. I didn't install any beta software and such. The current 'issues' I have with the phone are actually resolved -- given that VoIP is a real drain, my current battery lifetime is ok. Things will improve when I disable 3G data, which I need rarely (and most users too).

By the way, I have not disabled much on my iPhone: definitely disabled Location services because don't see a point to tell everybody where I am and Siri, because that thing does not speak my language and is pretty much useless for me (and also quite annoying in the default settings). Everything else is on, including iCloud, WiFi Sync etc. I don't use Push e-mail, because with the volume of mail I receive my phone would disturb me constantly.

By the way, if you are so disatisfied with your iPhone, go ahead and either exchange it or return for refund. No need to torment all of us and no, this forum is not for whining.

well, what is it about hearing a noise while speedtesting?

what does this affects the phone?

thanks

Normally the electronic components of phones should make no noise. If one makes then it means that it is faulty and also probably draws more energy than it should!

It affects the battery life!

@dkalchev

Ok. The battery life issue of iPhone 4s is due to using 3G network and Cellular data transfer. If one uses 2G network then there is no battery life issue anymore.

One cannot disable "3G data". There is no such thing in settings of iPhone 4s! I guess that you mean "Cellular Data". If one keeps the Cellular Data off because he or she rarely needs it, looks like one is using the iPhone 4s as an expensive music player (like for example iPod) and a dumb phone!!! What is the point of having a smart phone like iPhone 4s if one keeps off all the time Cellular data? There is no reason!

Also I agree with you that most of the iPhone 4s users keep the Cellular Data transfer off because maybe they do not have a Data plan or there is no such capability on their network. This explains why here many people think that the majority of iPhone 4s have no batter life issue becasue the batter life issue does not appear when the Cellular Data transfer is off or one is not connected to a 3G network.

@dkalchev

Again, Have you checked your iPhone 4s for the static noise issue? I bet that you are affected by it and most likely is that you are not aware of it! Over 80% of iPhone 4s are affected by the static noise issue

You are fixed on this Qualcomm chip, aren't you?

There are many more things in the iPhone that drain the battery in addition to 3G data. The improper management of the 3G radio only draws battery when idle. This is why I do the current experiment with my phone, to find out if this was fixed.

I find it amazing that you show how knowledgeable you are about iOS releases, yet do not know that you can already disable 3G data in iOS 5.1b3 --- 3G data is not the same as Cellular data, which includes 2G data (EDGE).

My phone had the same battery issue before the reset with Cellular Data OFF, than it had with it ON -- in fact it was slightly better with only 3G ON and WiFi OFF... but not much. Getting rid of background tasks improved things so much more (although admittably, especially in poor reception areas 3G data eats battery like nothing else).

The iPhone 4S has much more than the iPod Touch for example, not only the Qualcomm chip and the SIM card.

To give you an analogy, if you turn on all your available lights and all your available heating equipment in the house will surely increase your power consumption (and electric bill). Will you complain?

If you do complain, will you accept the advice to turn lights/heating only whete you need them?

For the guy saying that my phone is faulty if it only lasts 5 hours - i mean 5 HOURS OF HEAVY USAGE (with wifi and screen on, constantly tinkering with the phone, talking over wifi on skype etc).

5 hours is great.

Its about a day with light usage. But I am a a power user, so I need the external envelope battery. Thanks everyone for suggestions re improving battery life. I am especially grateful for static noise issue warning, will see if it's that bad.
