where is the 5.0.2 or 5.1 update (memory )  send to developpers about  battery ,memory problem that Apple send.

 

it s about 1.5 month ago!!!!!!!!!!!!

so..........no problem with that?..........just neverending discussion...652 pages........and no update that apple promise

like you'r  ok with that?

Franky, No one here knows when 5.1 will be released. It is currently in its 3rd beta and people are speculating very soon. There is no 5.0.2 to my knowledge. Apple has never mentioned any such update.

This is my last reply to you!

Ok Whatever you say.

Yeah, right...

As for how long 2 yrs? Well lets see, your math counts 3 months as 1 year so yeah if a patch is released by March that will be about 2 yrs. So you are close there!

I do not know what you count there but I was asking a question there. I was asking "will it take two years for Apple to fix the issues of iPhone 4s?". Did you notice the question mark? Is it wrong to ask questions? Obviously one is bothered if really simple questions are asked here on this forum. Instead of answering my question you are trying to prove a point by showing that the question is wrong.

Just so you know when new code is written, they are not trying to fix anything cause they dont know what does not work as expected yet.

Now should I fall on my back because "when new code is written, they are not trying to fix anything cause they dont know what does not work as expected yet.". Are you really serious? Should I fall on my back? What do you mean by "they dont know what does not work as.."? What do they know? Do they know anything?

Should one give a break to Apple and forgive Apple because one should understand that is difficult to write code? Are you really serious? Do you mean that Apple cannot hire thousands of programmers in China and fix fast some software bugs in days or weeks instead of months or years?

This is how I see it. Apple sold me an iPhone 4s which has many issues (bad quality voice, static noise issue, battery life issue, etc.) and which I paid with my own money (a lot of money by the way compared to other phones). I want the issues of my iPhone 4s to be fixed now (or yesteryear) or I want my money back from Apple. Apple sold me a crappy iPhone 4s and it is Apple's fault and nobody's else. I was not told when I bought the iPhone 4s that I will be some kind of guinea pig for months for testing their software of their iPhone 4s while also paying for it. Apple will not get any break from me just because I should understand software is difficult to write/fix. There are plenty of companies which sells smartphones and those companies can fix their software in days/weeks and not months and also acknowldge immediately the issues and not ignore the customers' complains.

Thats all I am trying to get into your head.

Exactly, this is my point which I was raising few posts ago. One tries to push his/her believes onto me! I do not want to get into my head that software is some kind of god and just because of that one should fall on his/her back when one hears the word software! All I want is, that when I buy a product with my own money (e.g. phone, tv, car, watch, etc.), to work as it is in specifications. As a buyer/customer I want to buy a product which works well and I do not want to hear excuses of why it does not work well. I do not buy a product to hear excuses like "you know it is a software issues and one should fall on his back when one hears the word software"!

Stop reading your posts! (really dont need to they are same the same thing over and over, 80% dont work, 80% have static, Apple will never fix it, 10 versions were released that did not fix it,should return and get money back)

So do you mean that you reply to my posts without reading my posts? You should have stated this in every reply to my posts!

My experience last night..

Took 4S off mains charge at around 9pm. Watched about an hour of TV (not using the phone) then went to bed. Set my alarm as normal, closed all my apps down in task manager. I have push email running for gmail, however I received no emails during the night.

Woke up at 7.45am to my alarm, noticed the low battery warning. Looked a little closer, 1% battery, with the following info:

Usage: 6 hours 3 minutes (by who? I was asleep!)

Standby: 11 hours 35 minutes (this is accurate to the time since the mains charge)

I was asleep, so what used my phone for 6 hours 3 minutes? A ghost?

Luckily I didn't set my alarm for 9am, otherwise my phone would have been dead before it had chance to wake me up from a 9.30pm full charge.

I can buy battery drains playing games, watching movies, browsing heavily.. but I was asleep with the phone in stand by mode under my pillow. That can't be normal.

I'm afraid not, i am a Radio Network Planner and Optimiser for a Mobile Phone Operator in the UK.

All communications through to a Base station are through radio and not GPS! Measurement Recording are received and an approximate distance to a base station is calculated. It may have calculated that the site is 550m away. The phone has no idea in which direction the basestation is in.

Sorry, your statement is wrong!

 

One may see easily that in iPhone 4s one has Settings -> Location Services -> System Services -> CELL NETWORK SEARCH which is by default ON and it is doing exactly that (i.e. using Location to search and connect to a cell network). If one has this ON and turns off the iPhone 4s and afterwards turns on the iPhone 4s then one could see easily that the GPS sign (violet arrow appears) is used for finding the network and the cell tower! Even worse, if one is inside the building the GPS wouldn't work and because of that iPhone 4s will get very confused and will take even longer to find a a cell network sometimes even fail to find one!

 

As I wrote before, it is very strange that a dumb phone can find easily and efficiently a cell network BUT iPhone 4s has the option to use GPS to find a cell network (Settings -> Location Services -> System Services -> CELL NETWORK SEARCH). It just shows that the Apple engineers are aware that iPhone 4s is not that good at finding a cell network and it needs help some time from the GPS to find it! My best guesses why Apple chose to do it this way is that:

1) they do not have the knowledge how to do it, or

2) Apple does not have the patent for the algorithm which finds efficiently and fast a cell network without the help of GPS.

 

Note 1: Using GPS to find cell network takes a lot of battery life unnecessarily!!!

Note 2: iPhone 4s is able to find also a cell network without using GPS but for this one has to turn off this "Settings -> Location Services -> System Services -> CELL NETWORK SEARCH"

Note 3: Settings -> Location Services -> System Services -> CELL NETWORK SEARCH is ON by default!

me too. i need a update for my iphone

im wating for 5.1

Did I write that the communication is done to a Base station are through radio and not GPS? No.

I am talking about iPhone 4s and your statement refers to phones in general! Still I fail to see how this contradicts what I wrote. I agree that this is how the mobile phones are doing in general and this is how it should be done. All I am saying is that iPhone 4s somehow and sometimes looks like is using also GPs while doing it.

How come that one sees the GPS being used on iPhone 4s in order to find a cell network when one turns on the iPhone 4s? This is the question.

A Radio Basestation does not transmit GPS data of its location. Therefore there is nothing for the iPhone4s to pick up to find its location.

All communication on establishing where a base station is through Radio Communications......depending on the technology 2G/3G, you will be looking for a BCCH on the 2G and a Scrambling Code for the 3G. None of which is through GPS...Turn your GPS off.....your phone still works......

I do not know what this feature is doing on the iPhone but it does have nothing to do with the location of a cell site.

@Mark_SRi

I have a feeling that we are talking about different things.

I agree with you 100%.

BUT for example Google, Apple, etc. have access to the databases of Radio Basestations all over the world (most of the world) and their GPS coordinates (e.g. this is how some Google apps installed on Symbian mobile phones with no GPS can still pinpoint someone's location on google map).

I agree with you 100%. This is how majority of the mobile phones are working and they are doing it well. The exception is the iPhone 4S. iPhone 4s seems that it might use:

1) its own built-in database of GPS coordinates of radio basestations, and

2) the GPS

in order to find/search the cell network. This is how it looks to me that iPhone 4S is doing and I have to say that if indeed iPhone 4s is doing it this way it is very very weird!!!!

I am trying to highlight here that iPhone 4S is very weird from this point of view and I do not like that iPhone 4s does it this way because it raises a lot of question marks! Also one should keep in mind that iPhone 4s can operate on CDMA and GSM networks.

I have done some searching, it is providing the user with no use whatsoever. It is your way of opting in or our of Apples program of them collecting your location data and what you are upto to sell on to other companies as marketing data.

See below:

Cell Network Search is a location based service that sends your location information, and the tower ids of the network towers within range of (and thus detected by) your phone.  It is used by Apple marketing (and whomever they choose to sell/share the database with)

Those features in System Services are all about sending your location based information TO Apple, not about enabling features or services on your iPhone.  This is Apple's way of allowing you to opt out of the collection of location based data that previously was done surriptiously without overtly letting you know or have any way to stop it.

You can disable every single feature in that section and your iPhone or iPad will continue to function exactly the same way it always has.

And back on topic,

I diabled all locations services, all applications closed. I went to bed at 11.15 and the phone was at 83% woke up at 6.45 and phone was at 39%. Thats 44% battery use over 7.5hrs doing nothing. I tell a lie, 1 text had been received!

So that works out at 88% battery usage in 15hrs, so in roughly 17hrs of doing nothing with the phone it will be dead...........i'm sorry but there is something wrong there!!! If i actually made a call of played a game, would be dead in hours!

I will be taking back to store in the next few days and cancelling if this carries on!

Mark,

I'm a little confused, under System Services, I see the settings: "Cell Network Search", "Compass Calibration", "Location Based iAds", "Traffic", these sound like they might affect how the phone functions, are you saying these can be diabled and the phone will still work properly?

Indeed it looks that my observation was not good ;-) Anyway, it is very weird name to have "Search Cell Network".

They are not needed, try yourself and switch them off. They will still work.
