128k or 256k sim card on iphone 4s?

Hi all from Turkey,

I just bought an iphone 4s 16gb black, and i am having the batteryu problems and so on (not so different then the discussion posted about 668 pages offerng the same things over and over again; time zone settings off, notificatins off, use of internet or mails only when needed etc. and i still feel stupid not going and getting another smartphone that will not prevent me from doing all these and drain a battery)

However, my question is not about to wait for the ios update or other usage questions.

Being an ex-andriod user, i had experienced a sim card issue on my previous phone.

At that time i used a 64k sim card, and till i swithced to a 128k sim, my exphone also drained battery(it wasnt an iphone i repeat)... After swithcing to 128 card, the problem was solved. (i don't want to name the brand or whatsoever, in the end, i thought i wasnt happy with it after one year, and now im on an iphone, not even able to check my mails with the fear of battery dying, while i listen to music...)

AT the moment, i am on a 128sim on an iphone 4s, and have been checking the web and community, searched for tech spec and all that, however, i could not fond a clear answer on what apple suggests to use with iphone 4s...

IS it better to switch to 256 ( more up-to-date ) card?

IS there any workaround on this?

ANd still, the battery is dead, charging at the moment,

WHat does apple "actually" suggest, for this battery drainage issue, other than to wait for an ios update--5.0.2 and more?

(my operator is Turkcell by the way if it will help...)

iPhone 4S, iOS 5.0.1

The iPhone uses a microSIM and does NOT store data on the SIM card. Thus, the storage capacity of the microSIM is irrelevant.

HI there gdgmacguy,

I am not a hardware expert though through what i experienced and saw is what a microsimcard happens to be my old 128sim cropped from around by the gsm operators, not another new card. However, from what i've read trough is, an up to date sim-micrisim whatever you name it, uses the hardware it is installed in to communicate with the satellite andsuch, thus old sims-microsims act loke drinking the battery.

I am not insisting if the subject is relevant or not, i am asking, what apple suggests. If That doesnt matter at all, i wonder what would happen with a 32k sim.

THanks in advance...

Not really. The SIM provides the identification to the cell carrier to link your iPhone with your account, but the SIM itself does not communicate with the cell towers. And as gdmacguy said, the iPhone does not use the SIM for storage. So while I can't say it would be impossible, I very much doubt that the amount of storage on any SIM would affect battery usage.

Apple says nothing about SIM capacity since the iPhone, again, doesn't store anything on the SIM. All Apple says is to use a compatible micro-SIM from your carrier. If you used a cut-down standard SIM, while those often work they are not supported and have been known to cause problems, though battery drain is not one of the problems I've seen associated with such a modified SIM. What Apple officially says about battery usage can be found here:

There are many other tips that have been posted in these forums, some of which have helped, so a search or browing of the forum might be worthwhile.

Regards.
