Not if the main bulk of your calls are with people on o2 and you utilise the free o2 to o2 calls

My iphone battery seems to be deminishing quicker than normal past couple of days. I dont have wifi and location services on by default as I know this hinders performance.

But is there anyway of seeing what is running and using battery on it??

Double click home and see what is running in the background, then close everything you aren't using.

Also put brightness as low as possible when you aren't using it.

Turning off 3g when you aren't using it is also helps save battery, but admittedly is a pain going in and out of settings to do so.

Sbsettings which previously was only for jailbroken iphones is now available for non-jailbroken iphones and let's you toggle stuff on and off with icons, without having to go through settings.

Everything on my iphone comes up. How do i close them? As there is no close option to get out of an app??

Hold your finger on the icon to make it wobble and a little red icon will appear on it. Click that to close it.

It's a pain to go through them all but on jailbroken phones you can do it with one click using removeBG and killbackground which are cydia tweaks.

I couldn't survive on 1gb internet per month. I use Sky Player on 3g all the time - as well as streaming Internet Radio.

GiffGaff is fairly good - offering unlimited Internet for a low monthly fee - but you would have to buy the iPhone separately. That's why I use the Three Network.

Buying on the One Plan (£40 per month) you get:

2,000 minutes
5,000 texts
All-you-can-eat data

and pay a one off fee of £49.00

or if you prefer, a one-off fee of £99, and just £35 per month.

One real benefit of the One Plan is tethering. You can use the iPhone as a WiFi hotspot when on the road, and tether your iPad or Laptop at no additional cost. Also, the AYCE data is expressly unlimited and not subject to any fair use policy. last month, I downloaded over 20GB.

I see, thanks Greybot. If I try and keep on top of it, it would be too much of a pain to keep clear. Do you know if that will stop notifications though?

True but giff gaff give you more free minutes for your buck and unlimited 3g on monthly contracts, so I can change depending on my usage. Sype keeps my international calls cheap or free and for all that I pay £10 a month. :p

It doesn't stop notifications. Just stops apps opening to where they last were opened (which uses more RAM and drains battery more).

The more notifications you turn off the more battery you will get too

Do you mind posting up what exact allowance you receive and pay?

Thanks James also for the info on 3, I wouldn't go over the minutes or text allowances so makes more sense to get unlimited 3g!

Cheers

250 free uk minutes, unlimited internet, unlimited texts, free to giffgaff calls for £10 a month.

Next one up is same as above but with 150 extra uk minutes for £15.

I have a fiver emergency in case I forget to top up but you can buy these packages in advance and am sorted up to end of February now so will have no downtime with 3g, free calls, free texts.

Have to own your phone but the savings from not being on a contract with someone else for a lot less of a deal, is well worth it.

Friend got it on an iphone 4, also works out best on the recommended deals from Money Saving Expert

IMO Apple really need to pay attention to battery life when developing the iPhone 5. It's been a constant thorn in the side of all iPhone models.

My battery was down to 9% by 11:30 yesterday morning! Grim times.

Its crazy, they design a phone with so many capabilities, but they can't even get the battery to last more than 24 hours if you use just some of those capabilities.

And when you look on Apple for advice on battery life, they basically say turn everything off and don't use applications. Whats the point in having them??

Yesterday, I unplugged in the morning about 7.30 and when I went to bed had about 8% battery left. I'm at work all day so hardly use it.

Yesterday I unplugged at 7:30, at 8 at the train station (3G) looked at twitter for about 5 minutes, and when my train came in at 8:06 I had 79% battery. It's ridiculous, has got significantly worse in the last two weeks or so though.

Why are you paying 31 a month o2's simplicity is £15 a month isnt it? though the data isnt great I doubt you would use that much, if you do then go with 3

If you go with 3

300 minutes and 3000 texts £15 1GB Internet (if you believe James and others 3 really have upped their game in fact they use the o2 network dont they?)

18x 15 = 270 + £499 phone = 769

The beauty is you dont need insurance as if you lose your phone just sign a contract and get one!

There must be some significant variation in the battery lives of iPhones then. My current iphone 4 is 18 months old, has everything switched on, l use it for browsing, using apps, photo's, videos etc regularly every day yet I only need to charge it every two days. Weird.

No one else answered it, but on checking my last bill, even though I "exceeded" the data allowance, I was not charged for data use, so thanks for providing the explanation.

My battery life is fine, incidentally, I usually charge it every other night, unless I've used it a lot during the day, in which case I charge it every night. Not a problem to plug it in overnight, is it?

Downloaded some special Battery charging app, which it says you should use once a month, so will see if that helps me.
