Q: iPhone 4s Battery Life?

So this could add to battery drain? Sorry I have not been on for a while so not seen your post, thank you for the reply :)

Thank you for your reply :)

Well, in case after reboot (power+home) I don't open any app which can use internet in background (like Skype) is it possible that it loads background process by itself? I use one app to look on processes but I don't understand most of them (except some obvious of course). Also I can track the internet traffic usage.. but there is no usage in standby.

Is it possible that it's hardware bug with cellular data modem?

I have just noticed, with the Bluetooth turned off, that process still runs to, that's also after closing all apps and soft resetting :)

@dkalchev

i see. thank you for the info, im still a noob iphone owner.

@sean-g11

my phone does dat too! i use iOptimizer and it shows mobile mail active in the process list when i dont even set an email account nor icloud mail.

Hey guys,

you just have to wait till march when 5.1 realeases and your battery is gonna be twice as good!

Are you promise, mazsi1911?

really? how'd u know?

i am using 5.1 beta 3 as my brother is a developer, i have 7-9 hours usage with 3G turned on, with normal daily uses, mostly web browsing as im travel a lot. more often i use tethering which doesnt eat my battery.. at least not as bad as it did on 5.0.1

IF you turn 3G off you will get better battery lifetime, for sure! That is why Apple decided to get it back in 5.1. They are no fool!

But that doesn't mean that the problem is fixed...someone already made a (great) comparison in this topic with a broken arm: You're in pain...you take pain killers and make the pain go away...but, until you get surgery, the broken arm will remain broken. You eliminate the symptoms, but the cause of the problem is still there!

The problem here is that no one knows for sure if there's in fact a hardware problem with the phones...

I hope that all of these battery drain issues are software related and the 5.1 will solve the vast majority of the problems (we know that other problems always show up, but that's something we'll have to live with)...

BUT we'll never be sure, unless Apple steps up...(and we all know that isn't going to happen).

The losses would be massive.

I see the delay as a good thing, or at least, I try to. Apple has always been silent about releasing updates, and this would be no different.

So, I'm inclined to believe that the engineers are working hard to try and solve the issues. They know that competition is fierce! And it's close, more than ever! They can't afford to miss! The iOS 5 alone has multiple variables concerning it's use...now, join that with the "Person" variable.

This can't be a "Simple" process...this is, in my opinion, the reason for the delay...or I wish it is!

Just trying to think rationally instead of emotionally...

EdiMC, The pain killer analogy is somewhat incorrect. By default the device is set to look for and connect to the fastest protocol (3G) so if you are in an area with some signal but poor signal it is going to try and connect to that. No way Apple can know if you are going to be in a poor signal area or not. YOU on the other hand will know this and the switch will give you an option to address it. So that in fact is a fix in my book. Now that is probably not the only contributing factor to poor battery life so any other fix is yet to be seen but my point in the 3G toggle is certainly a fix not a "pain killer" for that particular issue. (being in a poor 3G area). Its been an option always until iOS5 and 4s came out. And yes hopefully you are correct in your assumptions about the 5.1 update. I hope they get it right! Even if it takes another week or two.

I understand what your saying, but I was refering to the "big picture", and not only to the re-introduction of the 3G toggle.

If there is in fact a hardware problem with the antennas/chip (faulty component for instance) which causes the battery drain, it will be there, no matter what software changes you make.

So, disabling 3G allows you to "bypass" that problem. Whilst you don't use it...but if you need to use 3G in a permanent basis, you'll have heavy battery drain if the problem is in fact caused by faulty chip/antenna (the problem can be elsewhere, this is just an example).

Once the toggle is available again, the difference is that you'll have more energy left to spend because the phone, while in Sleep mode, wasn't draining battery at a high rate (like mine does now). So the problem could be "attenuated" - example of the broken arm applies in this particular condition.

If everything is ok with the phone components and this is software related (that is what I'm hoping for), an update should be able to fix this (or at least partially solve it).

See what I mean?

If the problem had been detected, things would be much easier...right now, it's kind of "I guess it can be this...or that...or even another thing...". Playing the lottery is pretty much the same lol

Cheers

Yes I agree! Hoping that pretty much all of the hardware can be updated/flashed with firmware to fix whatever if need be. Pretty typical option these days. Maybe one day if they ever release SOMETHING we will know.

Now you're starting to scare me a bit.   Instead of a 3G toggle, APPLE could always give you an optional setting for the phone to automatically select the better of available signals, when the 3G signal is marginal?   That's simple software logic.   To simply allow the phone to struggle with a marginal 3G signal and have the battery drain so quickly is not wise.   To force ME to be in there toggling 3G off and on is not user friendly.

But that is what the phone (supposedly) does...the thing is: What is a strong signal? What is a weak signal?

Even if the the automatic change was set to when the signal dropped from 2 to 1 bar (just an example), how would the phone know when to come back and search for stronger signal and switch to 3G? (above 2 bars).

The phone has to continuously monitor the network in order to achieve that...and then, the problem would be the same because searching for network signal requires large amounts of energy.

It looks simple to achieve, but it's not...

So, adding a 3G toggle, is practical...AND, it isn't "user friendly" ONLY because Apple refuses to add an option like SBSettings where sliding a finger on the top of the screen gives you access to many individual toggles: Wi-fi, 3G; Data; Location Services; Brightness; Bluetooth; Airplane Mode...

Nevertheless, I would prefer to have that option back, than not having it at all!
