Hi Guys I've bought a new 3G 16 GB iPad and it really is a nice gadget. I have a problem with the 3G though. At night in standby when connected to the XT network the iPad is draining 30% of it's charge. However if I leave it connected using the wifi only (with 3G off) it hardly drains at all at about 1%. All settings remain the same with push email on etc. I can replicate the issue by switching to 3G one night then back to wifi the next. Anyone else had the same issue?

I usually find it's time to recharge by bed time anyway. Any reason you can't just leave it plugged in? In any case, using 3G data will always drain your battery faster. The cell site is much further away than a WiGi access point - hence, more power required to send and receive radio signals. iPad + iPhone 4S + 2degrees 3G data 4tw! These comments are my own and do not represent the opinions of 2degrees.

Does it do this consistently every night? Strangely enough I have never experienced this problem with my iPad but every now and again the battery in my iPhone drains heavily overnight and I've never been able to establish any sort of pattern that might explain what's causing it. I can't help wondering if there is some sort of software bug that is causing this to happen just under certain circumstances.

Still excessive battery drain IMO. I live in a poor signal area and my iphone doesn't drain that quickly on standby. Might want to try recalibrating the battery or a restore/reset network settings.

I have good xt reception at home and the draining is pretty consistent. Using ms exchange push email. Also tried a full restore.

My 3GS uses about 60% overnight with 3G and the alarm set. I have to plug it in or I won't get woken up! With 3G turned off it will last 3 days or more without a charge... I wish it auto turned 3G off when connected to wifi!

We'll I've got something interesting to report regarding the draining battery. I tried my Vodafone micro SIM (real not cut) last night and there was virtually no battery drain at all - around 1%. The XT SIM I have was cut from a normal SIM by Telecom. I'm wondering if that caused some damage to the SIM which means it keeps dropping in and out of signal causing the battery drain. I dont have a "real" XT micro SIM to confirm but I'm testing another cut XT SIM today and will let you know how that goes.

You might also want to consider turning off spotlight. I did this on my ipad (none 3g) and it has improved battery performance. A friend that has a 3GS turned it off and has seen over twice the battery life. http://www.iphonewzealand.co.nz/2010/all/tip-switch-off-spotlight-and-improve-your-iphone-ipad-batte.../ Media centre PC - Case Silverstone LC16M with 2 X 80mm AcoustiFan DustPROOF, MOBO Gigabyte MA785GT-UD3H, CPU AMD X2 240 under volted, RAM 4 Gig DDR3 1033, HDD 120Gig System/512Gig data, Tuners 2 X Hauppauge HVR-3000, 1 X HVR-2200, Video Palit GT 220, Sound Realtek 886A HD (onboard), Optical LiteOn DH-401S Blue-ray using TotalMedia Theatre Power Corsair VX Series, 450W ATX PSU OS Windows 7 x64

The area I'm using it in has very good reception on both the XT and Vodafone network. We'll see how the other SIM goes.

Was just looking around the internet and seems that there are a few other people with battery drain issues that may have been caused by cut SIMS.

Wow if this proves to be the problem im glad i waited a week for Telecom to source me a micro sim. When you look at the Micro SIM versus a cut Normal SIM the gold pads are different sizes and slightly different positioning. Maybe the SIM (even though its working) is touching on a pin it shouldn't be?
