Q: iPhone 4s Battery Life?

I think that there should be some kind of law in USA and EU where the mobile phone manufactures should be obligated to state in specification how long a mobile phone lasts between charges in real life situations

Under which "real live situations"? Do you know how many variables there are? Temperature, cellular signal strength, screen brightness. Do you mean with location services enabled? Or without? While playing games? Or just while reading email? Push enabled? Your real life situation? Or mine? Can you see the problem with trying to give a single spec?

I was making a valid point with the sim card scenario, and no one in their right mind would think this phone drains 0.27% per hour on standby here. The specs do tell.

I don't come from Russia but what you are is a racist and ignorant bigot. You should apologize for such comments which stereotype Russia. Professional corporations exist in my jurisdiction to protect the public so that no 2 bit idiot like you may be allowed to build a mission critical system or build a dam and such without proper credentials and training.

They both are not from Russia. Russia has changed a lot in the past 20 years.

Your response is interesting but doesn't answer the problem.

1. Anyone who posts negative comments about IP4S, you(sbailey4) jump on their necks and squeeze them, aggressively defending apple(your employer, it appears so).

2. The 4S should provide at least 2-3 Days with very light usage, I normally use it to send text messages/read emails hourly, but even these simple tasks will never get beyond 36hrs of standby. PLUG IT IN as you suggested is not a solution, analogy, your bone in the arm is broken, take painkillers..well your arm will remain broken even if you  feel no pain.

3. The battery problem (mine and others)is not critical, but is poor, and this should not be hidden and sugar coated. You are trying to do this.

4. I don't want to switch to other brands, I like the 4S(it's very good) but I also acknowledge its weak/poor points. You should do the same.

See ya!

The iPhone 4S *does* last more than two full days (48 hours) on standby and light usage. I use mine with almost all settings on default (Disabled are: Siri, few location services, few notifications have disabled lock screen activation, brightness is 40% with auto brightness off). Everything is on, 3G, WiFi, iCloud, I am logged into App Store, FaceTime etc. I am also experimenting especially with the battery lifetime with an VoIP always on connection (I don't actually make calls via the builtin phone, during this experiment -- all my incoming and outgoing calls are via VoIP). Why I am mentioning this: VoIP keeps an constant network connection with it's server, which in turn keeps 3G/WiFi ON at all times. VoIP is also requiring much more processing from the CPU during call, thus wasting more battery. I understand this is not typical, but a typical setup would consume much less battery.

I am also recently using the phone more, for various apps, browsing, email. I set it up to pull mail every 15 minutes, and I let it download up to 1000 messages (my Inbox is much larger). This is again important, because after each download, the iPhone would sort the messages by conversations etc, which too, consumes battery power.

Here is what I had last night:

Racist? Hardly. It it even possible to be racist against communism that's now gone? My remark was aimed at your statement:  "engineers are supervised by a professional corporation". Sounds like your engineers used to report to Big Brother.

As for your asinne statement where only "civil, computer, geology or electronics" engineers are considered engineers, try, just try, to argue that Google's software engineers are not engineers.

I'm well aware of the phone's battery meter. Any first year computer science student could have told you reporting a value in integer format is not always ideal. My phone could report 98% but could actually be 97.5%. iOS could be taking the floor or the ceiling of the actual value. Unless you're an Apple engineer working on iOS you wouldn't know either.

Maybe part of your mandatory reading was also "The Fox and the Cat"? One may have many tricks and skills in his bag, but if one doesn't have common sense and logic, he will be undone. If I had half the skills some of you have this would have been such a no contest. I feel quite vindicated in that respect. Of course, everyone has his bias and agenda, but rest assured I have no desire or use for all that smartphone gadgetry. You haven't been here long enough to know what I stand for - or maybe you have. I stand for something quite human and technology as a rightful tool, not a lifestyle. Anyways.

I'm sorry for my poor attempt at comedy. My remark was really aimed at 1AppleADayNoWay's comment about living in a soceity where a  "engineers are supervised by a professional corporation" and that software engineers aren't engineers. It sounds like he's used to reporting to Big Brother.

1AppleADayNoWay will probably comment about how I don't know about societies of engineers and government regulations and whatnot. For that I can ask a college buddy who is a civil engineer. The same buddy sat next to me in an intro C++ class.

This all was already done by Apple in iOS and borrowed by Google in Android (to some extent). Now Microsoft will try their luck... As with everything from that company - wait and see. So far - everything is only theory and wishful thinking.

I quote you: "Maybe in Soviet Russia your engineers can get by stuffing a round peg into it's companion hole, but in the rest of the free world engineers are expected to have communication skills." I note the present tense and I rest my case on that. You just made a fool of yourself here. But you did say you were sorry afterwards. Fair enough.

As for your asinne statement where only "civil, computer, geology or electronics" engineers are considered engineers, try, just try, to argue that Google's software engineers are not engineers.

Listen, you'd wish an engineer had reading skills as well as communication skills. Nowhere did I say that only such engineers are engineers in your jurisdiction. I was explaining to you why engineers don't basically do support in mine. This is further compounded by cultural and language differences. A software developer or someone who even has a Ph.D. in computer science will not be an engineer by default in my jurisdiction, even a guy from Google - that is all. Some acts are reserved. I doubt in the U.S. someone like you can be allowed to program software for a nuclear plant simply because he's taken a C++ class. Plus the supervision I alluded to is basically to make sure he updates his knowlegdge by taking a prescribed number of courses over time and such other duties and regulations - because professionals are accountable to the public; they don't report to the state, they report to their peers who are organized in a professional corporation. You don't seem to be aware of the rules in your own jurisdiction, so  your comments have no substance. You're simply a judgmental type of person. Go ask your college buddy and learn something instead of rambling.

I'm well aware of the phone's battery meter. Any first year computer science student could have told you reporting a value in integer format is not always ideal. My phone could report 98% but could actually be 97.5%. iOS could be taking the floor or the ceiling of the actual value. Unless you're an Apple engineer working on iOS you wouldn't know either.

So you do understand the concept of uncertainty with calculations. Unfortunately I made myself a mistake by using it. But from context it was obvious I was talking about the fact that what happens from 100% to 98% cannot be made into a rule. It may be that everytime you discharge from 100% to 98% you'll have 7hrs of standby, but later on you'll have 2-3-4 times that 0.28% per hour so that from 100% to 0% it won't be much less than 0.5% on average. Otherwise following your logic you'd get almost 400hrs of standby time (so right, you can get 8 days on a charge with 45 mins of usage on every one of those days) - not happening. I can't believe I'm debating with you such futile stuff.

Well, their OS is beta so it's not surprising that we'll have to wait and see. But my comment was made as a compliment to Apple, which you failed to see. In the comments of that blog, I even tried to leverage MS's expertise by describing a situation that was maybe encoutered here with something like Magic Piano i.e. an app which is allowed to do stuff - too much of it - while in low power state. Fortunately, you can count on MS for including a free task manager to its OS so the user can monitor that, even though I could imagine a scenario where the task manager can't show what the app is doing. Anyways, I posted the link also because it's an example of really good technical writing.

I was one of those people that was losing about 10% of battery life per hour without even using my phone. After reading through alot of the terse 700+ page thread, did the following:

1. Reset All Settings (I had restored my iPhone 4S from an older backup, so thought it would be good to start with fresh settings).

2. Let my battery drain till phone was completely dead, and chanrged to 100% via an outlet.

3. I usually keep my phone ringer silet and the vibrate on, so I turned off sound/vibrate notifications for new emails, since I get hundreds of emails a day.

I have 5 different email accounts configured on the device, exchange and iCloud calendars, and locations services on. As of now, I've gone a full 24 hours since my last charge, and I'm at about 40% remaining battery life. This include several short calls and many text messages.

Would I like more battery life? Sure, but I'm pretty happy with the difference those 3 simple and easy changes made.

i thought vibration ate more battery?

I have not jumped on any "necks". If you read back through these 700 + pages you will see I have consistently offered solutions and tips and explanations.  For that I have been called mindless, troll, Apple lover, whatever. Been accused of telling folks to " turn everything off", which I have never stated.  I have simply quoted the Apple specs as they are stated as UP TO xxx hrs depending on which spec and pointed folks to an optimization page created by Apple to help get better results and closer to max spec. Offered other tips I have see work both on my own device and others here. For that I have been called names, told that I have recommended turn everything off, told that I claim there is no issue at all, told that I have defended Apple.  The fact is I have simply been here to offer help as I my self had poor battery out of the box. I thought wow this thing eats juice but it does do a lot. Then I found that Apple had confirmed a bug. planned an update to resolve. I applied the update, iOS 5.0.1, It made a huge difference. I have been told that it didn't over and over and over. Well I tend to believe what I can verify not what some nay sayer tells me. Then I found Apples optimization page, turned off crap I do not need or want. (apps seeing where i am all the time, time zone looking to see if I have gone across country all the time, etc etc,) After doing so, instead of plugging in again around 5:00pm I go to bed with 55% to 75% remaining after a days use. Or I wait and go 2 days on a charge just to see if it will from time to time. So I KNOW it can be made better and opt to come here to share that info with others. Plain and simple.

Apple lover? Troll? Whatever. I do happen to REALLY like my iPod nano gen 3 have had for years and enjoyed my 4s for a few months. That is all Apple experience I have had and do like them both. So ok Apple lover I am I suppose based on that. However I could care less if anyone else likes them, loves them, hates them. Makes not a single shread of difference to me. I have no vested interest if folks like or keep their iPhone or toss it, return it, throw it in the lake. I honestly 100% do not care so I am not defending Apple nor do I work for Apple. Yes I am offended when I am here to offer help and get all the negative comments.  Yes its dumb as **** when someone can plug in their phone but refuse to because of some spec states they "should" be able to last x hrs without doing so. Yes its dumb as **** for someone to have on every possible feature even ones they do not need, and refuse to turn anything off because it was on by default, and complain that the battery don't last.

However that is certainly your choice. But doing so will eat up battery period. Complaining, new iOS, new phone wont solve that. Not plugging it in wont solve that either. Plugging it in WILL help. But if you only want to plug in in every 3 days go for it. Just use it one day and look at it the other 2. Again your choice.

So you need 36 hrs that you are awake no where near an outlet or dc source?  If that's the case you probably purchased the wrong type of device.  An old school plain ole flip phone may well be better suited for you.

Again I an not defending anything here and if you hate Apple or your iPhone by all means get rid of it. There are WAY too many choices to be dissatisfied with a particular mobile phone.

No sugar coating and acknowledgement: PEOPLE VIEWING THIS THREAD, THE IPHONE WILL MOST LIKELY REQUIRE YOU TO PLUG IT IN DAILY. IF YOU HAVE ALL FEATURES ON YOU MAY HAVE TO MORE THAN ONCE A DAY. IF THAT IS NOT AGREEABLE TO YOU RETURN YOUR DEVICE FOR A REFUND. IT MOST LIKELY WONT LAST FOR A WEEK AS SOME ARE EXPECTING IT TO. SORRY

Stop trying to change the subject. I'm going to redirect this back to this:

So far the iP4S behaves about the same as the iP4 that it replaced.

Unfortunately, you cannot claim that - at least because it's rated for 200 standby hrs vs. 300 hrs for the 4. That simply means the phone uses more juice when on standby - in fact 33% more, which is not "about the same".

Remember that quote? How about I quote Anandtech (again)?

From Anandtech:

 

Power at idle and during application launches was pretty much unchanged between the two devices, which is to be expected. The 4S did draw measurably more power loading web pages. As we've already seen however, the average performance gain in our web page loading tests was over 30%, easily making up for the increase in power draw here. Maps however pulled more power on the 4S.

 

What does all of this mean? The iPhone 4S has the potential to have slightly better, equal or much worse battery life than the iPhone 4. It really depends on your workload. If you're mostly browsing the web, the 4S should be about equal to if not slightly better than the 4. Our numbers seem to back that up:

I've stated that my usage my iP4S is comparable to the iP4 it replaced. You tell me I can't make that claim. I provide proof by referring you back to Anandtech, the website you like to reference. Are you going to contradict your source?

Did I miscontrue anything that I posted above?

You're simply a judgmental type of person.

In this instance I'm not being judgemental, I'm being correct. I actually use my phone every day, many times to the point of completely draining the battery.
