Iphone download. Please help!

Surely you mean try leaving the battery out for a while Macky?





You tried plugging it into the mains? Not sure if iPhones do the same but my old iPod classic will only charge through the mains if it has been completely drained. USB sockets run at a lower voltage than the mains.

They didn't ask me at apple care but, yes I tried that. It's rare I charge through the USB.

Fair enough, might not be the same on the iPhones then. I had originally typed take it to one of the Geeks as Apple are fantastic on aftersales & support to be fair but then I remembered the iPod thing so thought it would be worth a try.

Glad you're getting it sorted either way though

Nope

You can't remove the battery on an iPhone I don't believe.

Assuming you're talking about a mains charger, rather than just trying to put 240 volts through it... the output voltage of the charger and a USB socket will be the same (5 volts). It's the ampage that will be different. You get 0.5 amps from a standard USB socket, I've got various USB chargers that range from 0.35 amps to 2.1 amps for various gadgets.

To be fair, he is factually correct in his confusion. There's about 235 volts in the difference

Errr, not quite. UK mains voltage is 230 volts not 240.

Is it after changing then? It was 240 when I was an electrician about 15 years ago

Has it changed fairly recently?
I'm sure it used to be 240.

According to Wikipedia...

Since 1960, the supply voltage in UK domestic premises has been 240 V AC (RMS) at 50 Hz. In 1988, a Europe-wide agreement was reached to unify the various national voltages, which ranged at the time from 220 V to 240 V, to a common European standard of 230V (CENELEC Harmonization Document HD 472 S1:1988).
The standard nominal supply voltage in domestic single-phase 50 Hz installations in the UK is still 240V AC (RMS), but since 1 January 1995 (Electricity Supply Regulations, SI 1994, No. 3021) this has an asymmetric voltage tolerance of 230 V+10%−6% (253–216.2 V), which covers the same voltage range as continental 220 V supplies to the new unified 230 V standard. This was supposed to be widened to 230 V ±10% (253–207 V), but the time of this change has been put back repeatedly and as of 2007 is set for 2008 (BS 7697). The old standard was 240 V ±6% (254.4–225.6 V), which is mostly contained within the new range, and so in practice suppliers have had no reason to actually change voltages.

No and yes. They've 'harmonised' with Europe and the stated voltage is 230v, but with the allowed tolerance of +/- 10% they've not actually changed anything. So, it is still 240v-ish

The good news is that I now have a new iPhone. They could see the crack was superficial and I bought a new back for £20 to revalidate the guarantee then took a replacement home with me. Thanks everyone for your advice.

When I plugged the new phone in I was asked by iTunes whether this was a new phone. Without thinking I hit no. I've checked and the serial number and IMEI are of my old phone. Is there a way I can back up the new phone?
