Q: iPhone 4s Battery Life?

Sorry to be iIrrational. Why are you asking users what they have to expect? Are you an apple product manager?

I'm really not doing anything intensive, text messaging, whatsapp, browsing occasionally and a few calls, would expect the phone to last more than its current 7 hours. 3G signal full strength I have a booster installed by the network. Sim card brand new the day I bought the phone.

My expectations of a full days use with only having to put the phone on charge at night are not unreasonable. Apple can't expect me to start work at 8am and be scrambling for a charger by 3pm. The phone oes not even come close, not by a long shot to the advertised specs. I just hope by Wednesday 11th (if that's true) that iTunes will get me the more updated firmware than I have now.

I can actually sit and watch my battery drop 3-5% in just a Few minutes of chatting to someone on whatsapp and then I can chat for 5 minutes more and not see it drop even by 1% .... You gotta admit that's not right, something in the background is chewing battery big time. Its also not isolated to my phone only, my dad bought one same day and has same poor battery life.

I'm not new to phones or smartphones. My blackberry used to give me 2 days before a charge and blackberry accesses the network constantly for messages. I have a friend with a galaxy s2 who goes 2.5 days on a single charge, he does not limit how much he browses, how many messages he sends, how many whatsapp chats he has, why must I?

What is "SMART PHONE" about having to turn all the features of ios5 off? What's smart about limiting what I do just in case the battery runs out? These phones are designed to be used, I don't think the big boys at apple run to a charger every 5 -7 hours, I assume they're smarter than that.

All I can say is I hope iTunes detects an update later this week because I'm convinced the firmware version I have 9a405 is super buggy.

Let's not forget the slogan for iPhone 4s "picking up where amazing left off" ..... That means it should surpass what the iPhone 4 can do and that INCLUDES battery life.

Finally why can my iPad last 3-4 days of some pretty heavy usage and the iPhone only 5-7 hours?

As I stated before, I have no connection with Apple beyond owning an iPhone 4S, which is my first Apple product ever.  However, I have been in the IT business since 1965, and have owned a computer since 1981.  Never liked Apple computers.

It seems to me that something is running in the background to generate that usage number.  Trying to track down just what that is may be a job for someone with a lot of technical expertise.

Well, the obvious answer is that the iPad has a much larger battery.  And the other is that it isn't supporting 3G radios....

Hope someone reads this and is willing to test the same.

I noticed that WIFI is connected continuously using the logging on my Draytek router. My routers access point (AP) logs an entry when a wireless device connects but in this case, and more importantly, also when it disconnects. I see the MAC address of my 4S being associated to the routers AP but when i lock the 4S, it never disconnects. This is weird since my old iPhone 2G disconnects from the access point 30 seconds after i've locking it. This situation will drain the 4S' battery more quickly.

I noticed in my DNS logs every few minutes a dns request coming by for pushmail, every 10 minutes or so. Now, i dont have Mobile data enabled when i'm at home, just wifi. Could it be that because of having Mobile data disabled, it enables the wifi interface the do the pushmail request and keeps it enabled?

Now get this, i enabled Mobile data and after locking the 4S, within a few seconds the Wifi interface disconnects. This means when using pushmail, it forces the WIFI interface to come online in the case when Mobile data is disabled.

John.

My iPad is the wifi+3G model with both turned on all the time.

I agree hunting down the culprit is already proving to be fruitless, I've already proven location services (in my case anyway) is not the cause. Hoping next update will rectify.

Will you get paid or get any gifts for your posts here?

1%-1.5% drop is equal to 75-100 hours stand by. In iPhone 4s terms that good

 

Compared to the situation that people are facing on these threads it is good. But it still isn't as good as those stats, which is what some people on here are complaining about now!!!

I fail to understand ...

One does not have to understand!!!

I didn't but a smartphone to let it sit for several days without use, and expect it to be ready to use after a week sitting around.

Here it is not even one post where one is asking for iPhone 4S to last one week!!! From where did you get that? Here most of the posts complain that the battery life of iPhone 4S is worse than the battery life of iPhone 4 or iPhone 3GS in exactly the same conditions!!!!

Worrying about standby time over 24 hours is like arguing about how many angels can dance on the head of a pin.

I cannot believe that such posts are allowed to be posted here!

Already almost three months have passed and no software/firmware update fixed the battery life issue in iPhone 4S!

Also one should look to the history:

- iOS 5.0 beta => battery life issue was not fixed

- iOS 5.0 => battery life issue was not fixed

- iOS 5.0.1 beta => battery life issue was not fixed

- iOS 5.0.1 build 1 => battery life issue was not fixed

- iOS 5.0.1 build 2 => battery life issue was not fixed

- iOS 5.1 beta 1=> battery life issue was not fixed

- iOS 5.1 beta 2 => battery life issue was not fixed

Why one expects that iOS 5.1 will fix the battery life issue if it has not been fixed in the last 7 iOS updates?

How many more iOS updates are necessary to fix the battery life issue?

You really can't read, can you? How did you view this thread since it hit the 100k mark if you can't understand the meaning behind the letters? I DID NOT MAKE 40 minutes of calls, the phone generates activity (USAGE) on it's own and yes, the difference is drastic just by turning celldata off. At least with me. Stop behaving like a ***** in virtual freeland!

 

For your proof,AND A REFERENCE TO WHOEVER IS INTERESTED, here's a screenshot of my device today with over 1 day of standby and 1h 34m usage (which is NOT realistic, I have barely called and did NOT use the phone at all for the purpose of this test. I recon I have no more than 30-35 minutes of calls and NO other usage).

 

Granted I didn`t properly read. You didn`t make 40 mins of calls, you made 30-35. I`m really off the mark. But you can`t read either - background processing counts as usage so your 1 hour on top of those 34 mins comes from that i.e. a few mins per hour for 24hrs of standby. This will be autochecking of email and other apps polling through your wifi. It is clear you don`t have any standby drain issues with that setup, but you also don`t have a 3G smartphone with that setup so I fail to see the point. I mean, you now have a wifi phone. Bravo! And good luck with that!

p.s. thought I`d paste the definition from the link you didn`t read:

Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.

SERIOUSLY?   You are truly asking that question?

Let's take a wild guess here....   iPad is 5X the size of the iPhone.   Maybe the battery is bigger, too?   :-/
