Q: iPhone 4s Battery Life?

This will be somewhat verbose..

My tests so far were focused on extending standby time. My setup includes an allways on VoIP connection. The connection is set up via TCP, with 900 seconds timeout, as I move frequently and connectivity might change even on 3G. This may not be typical setup, but is currently of interest to me.

By far the most significant improvement was the Network Settings Reset. I had only couple of wifi networks remembered, so there must be some issue with the GSM carrier. Perhaps some pre-programming or provisioning by the carrier... I don't yet have explanation of this issue. (needs more testing)

It is also possible that the new modem firmware in 9A406 has improved 3G performance, but I hasted to install it before doing enough tests to gather usable statistics.

I verified that for standby, having WiFi ON at all times is better than 3G. Not significant, but noticeable few percent improvement.

"Ask to Join  Networks" is disabled -- useful feature, but definitely causing more radio work. This setting should not have much effect in standby, unless you have very fluctuating wifi coverage, but I have not verified this yet.

If it has significant impact on standby, then there is a software issue that has to be resolved.

I am not done with this experiment yet.

I have disabled automatic send of diagnostics data. Not confident this has much to do with battery drain in standby. But one thing worth noting is that before Restore to 9A406, the number of reports was very high. After the restore, for few days there was not single report -- last two days I have few lowmemory reports, caused by Mail -- I have configured the client to fetch 1000 messages from the server and my Inbox is much larger.

I am not done with this experiment yet.

Siri is disabled. Especially the "Raise to Speak" feature. I find it quite annoying when answering an VoIP call, that Siri would wake up and listen to what I have to say to the other party, then claiming she didn't understand what I asked

I believe, there is no need to disable Siri in order to conserve battery -- just disable "Raise to Speak".

Perhaps, Siri will not wake up during normal voice call --- so there should be some arrangement to not wake up during VoIP call as well.

According to the description of how the infrared sensor whorks however, leaving "Raise to Speak" enabled during extensive use of the iPhone would additionaly and unnecesary drain the battery.

I have removed number of applications, many of which had Notifications in the lock screen. Such applications are supposed to get chance to run during standby. This is likely to lead to significant improvement in battery life.

One of the issues of 'poor battery life' is the need for the litium-ion battery to recharge few times to be able to keep more charge.

Each new charge cycle improves battery life, so this only supports this well known fact.

I suspect that iPhone 4S might come with new battery that needs few more cycles to condition and this contributes to the suboptimal initial experience.

Having large number of applications that can use Location services is causing more battery drain. The GPS unit apparently consumes more and some of the services would additionaly send data via 3G at the same time. Presumably, the 'asisted' GPS also engages all radios.

Other settings that my iPhone has:

Bluetooth is ON, I have apparently forgot to switch it off, but no devices are connected.

iTunes Sync is ON, it syncs one-two times a day (eventually exchanging some apps, that I tried during the day).

Spotlight search is ON for everything.

Siri is disabled. I have no use of this feature yet: doesn't understand my language and doesn't provide any service in my country.

I have iCloud ON, for Contacts, Calendars, Reminders and Bookmarks, Documents & Data. Photostream is ON as well. Find my iPhone is ON.

Mail is set to fetch every 15 minutes, IMAP, 1000 recent messages.

Twitter is configured.

Location services are ON for Find Friends, Weather and Find My iPhone. System services are all off.

Notifications: Phone, Messages, Reminders, Calendar, Twitter, Find Friends have enabled notifications in the lock screen. Weather widget, Game Center and Stock Windet are with Notification center disabled.

FYI I don't have the static problem and my phone is still going strong after one day So please calm yourself, ser

You've been trolling here for at least a month. If you don't use a smartphone why are you here? Are you lonely? Are you looking for a date? Are you looking for attention?

 

I said, "I compare my heavy usage to benchmarks where a phone is tested and I know the battery is inline to what reviewers are seeing." I've read Anandtech reviews, among many others, and I don't have to lie about my phone usage.

 

In your words you don't use a smartphone at all and you want question me about heavy phone use? One of the few smartphones that can currently make it through a whole day of heavy use is the Droid Maxx and that's due to its massive battery.

 

Where did I say that the iP4S isn't outclassed in some aspects by some devices? The truth is you're grasping at straws and trying to change the subject.

 

The Big Bang theory is not a good show. Since my remark flew right over your head let me explain it to you. You want to comment on something you don't use, but you are trying to pass yourself off as knowledgeable. Please comment on the unified field theory, another field of study you don't understand.

I'm here for the likes of you - and I've been there for longer than a month. I'm here to scrape the sugar coat. I didn't want all your attention, so you can go back to Infinity Blade now. You see, I don't care for your personal experience, but you claim things yet you don't disclose them. You don't have to but then don't come back with a useless post. The only thing I've done is disclosing the numbers from Anandtech and challenging some of your statements - it may rock your world I concede. I'm at a loss as to why I need to use a smartphone to have a discussion on the numbers and reviews, or general knowledge, plus the terms of use of the forum don't require you to own a device to register or post here so get lost with that. Like a few others here, you seem to think that your experience is world-defining - you may define yourself through your phone use but I do not. Plus I've been here long enough to see how this phone behaves - there are variations with issues and with results, but there are some trends. I have explained through many recent posts my take on that phone. It is up there at the top of its class. But it is not in a class of its own, or out of this world. And it is certainly not "perfect". And I'm not doing a dance for you buddy - go ask Siri where to find that. Hands on experience is just entirely irrelevant here so your point is moot - it has nothing to do with knowledge. Were I to own an iPhone I fail to see how this would instruct me as to what hundreds of other people are experiencing. You should start with basic logic before going into astrophysics.

You're here for kicks. Don't pretend otherwise. No where did I say my experiences are world defining. You've stated you don't use a smartphone. What would you know about usage? The same news everyone has read from iP4S reviews? Since you love quoting Anandtech, here you go:

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:

 

Oh, but I'm constructing an elaborate fantasy when I saw that my iP4s usage resembles my iP4 usage.

<yawn> If you need my approval to confirm your undisclosed iP4S usage "resembles" your iP4 usage, well you were constructing an elaborate fantasy about what our discussion was about - and congratulations for proving something to yourself without disclosing your usage or settings to no one while preserving your sanity - bravo. I don't care about you or your usage or your ego. I was merely stating that "picking up where amazing left off" certainly doesn't apply to battery life in terms of standby time or to 3D gaming time on the 4S. You lost sight of what this was about really. So feel free to move on.

I suggested that the battery life issue will come in maximum two days! Let's talk then!

So please calm yourself, ser

I am more calm than you! I am not the one here who gives high five to others on a forum meant for complains!!! I think that one who gives high fives is more excited than me and should follow its own advice!

How do you know that the battery issue will come back? Are you psychic? Are you a fortune teller?

Also, you say you are calm but you are the one who is constantly using exclamation points Excited much?

Venturing a guess, it appears as though all iPhones are affected. It seems almost impossible for so many of these units, all purchased at different times and locations, to be affected in such a consistent way. The majority of users probably do not notice the static either because they can't hear it or think it's normal or simply don't want to appear crazy. When I took it to the Genius Bar the woman dialed the phone from a house line and swore to me should could hear no static. When I took the phone from her I heard it immediately, but that's because I knew what to listen to. I work in the microelectronics industry and when integrated circuits make this kind of noise, the issue tends to be related to (1) incorrect voltage or (2) a faulty component. Faulty components can continue to work within expected parameters, but will emit an electronic buzz/humm/static/whine/crackling. I'm doubtful that Apple can ever solve this issue with a software fix, but they may be able to fix it by identifying the issue and fixing it in their future production. At that stage it's probably going to be worthwhile to get a replacement -- assuming that Apple's service stock has caught up, which is definitely not going to happen for a while even after the issue has been fixed.

===========================================

 

from here:

 

https://discussions.apple.com/thread/3393647?start=705&tstart=0

 

 

 

Also, by the way the same guru you quote suggests getting a replacement is worthless (I happen to agree with him on this )

If one would have read the entire post would have also read this:

and that also the post was written last year in December.

Why would you give advice to your victims to get a replacement?

 

Please, again read what that person wrote, which is:

By the way, I doubt that person who "worked in the microelectronics industry" will dare stand before his boss and tell him the same "diagnostics".

Wawww... this is a new low here. If one cannot anymore attack the post itself then one will attack the person who wrote the post. If that does not work then it will get involved even the boss of the person who wrote the post!!!

I suggest that one to judge the posts and not the people who write those posts. The people who write posts here can have any kind of bosses, can have any kind of believes, can have any kind of native language, can have or not a driving license!

I suggested and suggest that you post your opinion/reply directly on that forum to "cel" because you wrote here about him:

If one would spend some time to read the posts on this forum then one will see that this forum is full of posts of peopel who did restore/resets/updates/etc. and declared their iPhone 4s free of battery life issue after 1-36 hours! The same people later came back and wrote that the battery life issue came back! One does not have to be genius to see this!

Are you psychic?

No. Does one have to be psychic to predict the elections results 24-hours before based on a smaller sample of people? No. It is just statistics!

One does not obviously like my exclamations marks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I suggest gently that if one does not like my exclamation marks then one should not read my posts!!!!!!!!!!!!!!!!!!

Not at all.

Also one should note that a forum of complains is not a place to feel excited by giving high-fives!

In my book people endng every sentence with an exclamation sign are by no means calm.

But your highest education might suggest otherwise.

@dkalchev

@dkalchev

This is a forum for complaining about the battery life issue of iPhone 4s.

The battery life of iPhone 4s is horrible compared to the battery life of iPhone 4!!!!! The battery life issue of iPhone 4s and/or static noise issue are hardware issues which cannot be fixed by software updates, resets, restores, etc.

I suggested gently that if one thinks that one might have the battery life issue then one should get a new replacement or get a refund! It might be that Apple has fixed hardware issue quietly by now (the battery life issue of iPhone 4s is quit old by now and it started last year) and the new iPhone 4s might be free of the these kind of issues!

Anyway it is Apple's fault and Apple has to deal with it and not its customers!

NOTE: If one does not like my posts or my posts violate one's believes (belief like in religion) please do not read them!

One does not have to be genius to realize that not all people come back, and that some people's batteries actually do get fixed

You say it's statistics - your statistics involve only the group of people with battery problems that come back - you are ignoring the people who never had problems, and those who manage to fix it. They exist, you know What kind of math is that? Again like you said, one does not have to be genius to know this

 

Also, you say you are calm but you are the one who is constantly using exclamation points

I didn't say I disliked them or anything. I'm just saying that exclamation marks are used for, well you know, exclaiming, yelling. So, calm down and I think people would take you more seriously.

Excited much?

Not at all.

Also one should note that a forum of complains is not a place to feel excited by giving high-fives!

 

Hey, who doesn't like getting high-fives from friends? It's a fun thing to do. And who are you to tell me what not to give in this forum? You are so funny because you are using my high-five so much against me, I think it's because you've got nothing else

I suggest that one to judge the posts and not the people who write those posts.

I am judging your posts and I think they are silly. I don't know nor do I care who you are or how high your degree of education you have or how smart you are.

Did you actually purchase that "super expensive" iPhone, or you just looked at the price and went to "complaint" forums to convince yourself you did well to not buy it?

If you had actually purchased an iPhone and used it, you would soon realize that all you wrote so far is FUD.

Instead of telling you fairy tales of someone else's post about someone else's perhaps experience with some iPhone 4S, why not just restrict yourself to your own experience with your own iPhone 4S?

So, how does your iPhone keep up with the defective Qualcomm chip? How long does it live after full charge? What are your settings? What apps do you use and how often? How soon did the Qualcomm chip become defective again on your very own iPhone -- after you seemingly cured your battery problem, that is?

How many iPhone 4S's did you return for exchange and what is your observation with regards to the newer units? Did they also have that same defective Qualcomm chip, that.. as you read somewhere, cannot be fixed by software.

Do all your replacement iPhone 4S's have the 'static noise'?
