The WiFi is turned off when you put your phone to sleep so I don't think it would make any difference if WiFi is set to on or off.

Interesting, I've not watched it while it's asleep, just going to sleep and waking up I see it disassociate then re-associate to my wireless.

Set your Mail settings so that it is set to manual, that should stop the WiFi (or 3G/Edge/GPRS) being used during sleep.

Another tip to help save power is to turn off the vibrate option in Sounds. I only turn it on in noisy situations.
I also invested in an emergency battery charger so I'm never caught short (or flat, rather) - works out to approx $33 with postage, comes fully charged & uses the iphone usb cable to recharge:

Great to hear. That's why I made the thread  . iPhonetosh is me, it was a very old account made on my dads work laptop ages ago and was still logged in.

If it is really cold and stalls, it may take some effort to start up. Same with a battery. If it is drained, it may take a while to start charging, if it even does.

Great post. Can i add here though that if you have completely drained your iphone and as stated above, itunes can take a ridiculous amount of time to charge up again, i have found using the A/C adaptor charges it up much faster and "wakes" it up, immediately.

I would actually like the next gen iPhones to have 2 switches on the side of the phone to switch on/off wifi and 3G like the mute switch.
This makes it much easier to conserve battery life and then easily and very quickly turn on/off wifi and 3G.

I installed a program via Cydia called WiFi Toggle - best application ever for battery saving! I do agree a quicker way to turn 3G on & Off and WiFi On & Off would be appreciated |

Yep, if you're checking mail hourly, the iPhone wakes up hourly - it starts checking mail (via 3G or 2G which is already on) then as wifi connects it switches to wifi for the rest of the mail check, then goes back to sleep.
I assume wifi is more power efficient than checking mail over 3G (and even if it's not, I'd prefer to use my wifi). But connecting via 3G AND powering up wifi and switching to wifi is the worst of both worlds. Ideally when checking hourly, the iphone would wait 5 seconds until wifi was connected (that seems an easy fix for apple).
ps.
If I had my choice, I'd want the phone to switch into 2G overnight (at midnight?) and not check my mail hourly. In the morning it can check my mail and switch 3G on (at 6:30am? or perhaps 1 minute before the iPhone alarm goes off?) |

I guess 3G is the main culprit that's causing me to charge every 1.5 day, which is way too often, considering how I only have to charge once every 5 days with my last mobile phone.
Thanks for the tip!
