    I have been on the fence on 3G vs wifi. What it comes down to is the how the battery holds up when tethering a wifi iPad with an iphone 3GS. Does anyone know how fast the battery gets drained when you tether?

    If you're referring to the battery life on the iPhone, mine drains 10% every 30 minutes. (3GS)

    The WiFi + tethered iPad should have longer battery life than iPad 3G.

    You're going to run out of battery on the iPhone LONG before the iPad....

    People are saying about 1.5 hours constant use for iPhone battery life when tethering through it... The iPad still goes strong though.

    Think about it. On iPhone 3GS or 3G, both WiFi and 3G has to be on and working overload at same time. That'll consume the battery so fast, (it's anywhere from 10-20% per 30 min) it's not going to be the same comparsion to the 3G unit that only needs the 3G antenna on and WiFi off. It'll last the full 6-8 hours and don't think your iPhone will hold on for any longer than 2-3 hours either. The battery in iPad is twice or more the battery capacity of iPhone as well. You use the iPhone as a backup/failover, not as a primary method of accessing the Internet for iPad WiFi. As T406 mentioned below, you can get several power storage units to extend the battery of your iPhone 3G. Then again, now you have to consider the extra inconvenience of carrying extra devices, power units, and the weight will be heavier.

    What? That's completely backwards. Tethering from a small phone with a small battery will last much shorter than a full out iPad drawing it right from the source. The iPhone will be using BOTH the 3G AND WiFi antenna, two of the most battery requiring things at once. I'm lucky to get 2 hours of battery life with MyWi on my 3GS. iPad says 9 hours on 3G.

    Even by your measurement (which I think is incredibly incorrect) it would only last 5 hours, just over half of what the iPad is capable of.

    He is simply talking about the iPad without taking into account the iPhone. Saying that the iPad gets more battery over the tethered wiFi network rather than using iPad 3g.

    Well worth it. Especially when you consider that you will triple that with one month on the 3G iPad. I have been using this settup since I got my iPad a week after launch.

    I have used MyWi with my 3G plugged into my laptop at work (for power to the iPhone, no wireless at work), my netbook connects to the iPhone and I have downloaded and installed service packs on my netbook. Worked great.

    Keep your iphone well vented as the iPhone will heat up a lot if covered in a pocket when using MyWi

    This is one of two "mysteries that aren't" on this board ... the battery life of a 3g iPad.

    It's been posted on Apple's site in plain English for a while now (two weeks?).

    The other "mystery that isn't" is why Apple requires you to use a credit or debit card with your name on it to buy an iPad.

    For the record, if you go by Apple's published data - if you use another device for tethering, your iPad is using wifi, so the iPad itself will last approx. 10 hours of Web browsing. However, it's unlikely that whatever you are tethering will last nearly that long. The effective battery life will be gated by whatever device lasts the least long.

    Huh, you're seriously telling me you are having a problem with me telling a person to think about a specific issue that relates to their question which could help them to come up with an answer on their own?

    It's a common expression that people use every day in life and it does not intend to insult anybody in general other than asking them to think about a certain thing.

    I was not implying anything, what i implied was exactly what i said. I wanted the OP to think. I never said he wasn't thinking in general.
