More iPad Battery Notes: 25-Hour Hotspot Life, 2-Amp Current Draw from Discharged State

Much has been made of the increase in battery capacity in the new iPad over the past week and a half, including its impact on charging and heat issues experienced by consumers. More recent discussions have focused on the device charging beyond the 100% indicator.

A few other tidbits related to the device's battery are gaining some exposure, information which may help users plan how they use their iPads. First, a report from AnandTech addressing battery life has been gaining renewed interest for its revelation that users running a Verizon iPad in personal hotspot mode can see as much as 25 hours of battery life to provide connectivity for their other devices. That number has also been confirmed by The Verge.

While Verizon is including personal hotspot functionality in its iPad data plans at no extra charge, AT&T has yet to announced whether it will even support the feature at all, noting only that it is "working with Apple" on the issue.


Meanwhile, VR-Zone notes that the new iPad can draw as much as 2 amps of current when charging the battery from a nearly-depleted state, pushing the capacity of charging connections such as computer USB ports. Apple's supplied iPad power adapter provides for up to 2.1 amps of current from a wall outlet, and the company has long noted that this method offers the fastest charging on any iPad. Users can, however, still charge the device using the smaller 1-amp adapter included with an iPhone or by connecting the dock connector cable directly to a computer's USB port. VR-Zone notes:
As you can see in the video below, the iPad in question only had seven percent battery life remaining and at this point it's sucking 1.98A. That's a lot of power and we were told by Gigabyte that they've seen it hitting just over 2A. That said, as you might've noticed from the picture above, this quickly drops once the iPad begins to charge, but considering a standard USB 2.0 port only delivers 500mA and even a USB 3.0 port will only deliver 900mA, you have to wonder how much Apple cares about PC owners.
The new iPad carries a 42.5 watt-hour battery, roughly 70% larger in capacity and size than the 25 watt-hour battery found in the iPad 2.

I think the new iPad sucks.

Just plug the damn thing into a wall outlet. Good grief. Apple supplies one with it. Why not use it?

You're in the minority. The display alone puts it *WAY, WAY* ahead of the previous two generations. It's the one to have.

That is absolutely ridiculous. Because a PC owner's USB port doesn't supply as much power as the included charger for the 3rd generation iPad, Apple is screwing over their PC owning customers? :rolleyes:

EDIT:

It's not like Apple can just go back and change the USB port specs. Obviously the iPad needs this amount of power to run their device, and they're not making it require so much power just to be jerks. That comment make absolutely no sense to me.

How many netbooks can charge over USB from a PC?

Seems like you should be pointing those out to me, VR-Zone, if you're trying to prove to me that this is something that devices with screens like this should be doing. I'm assuming it's a long list for you to make a comment like that. Would be nice of you to share.

Apple cares so much they included a charger so PC owners can charge their iPad from the same outlet they plug their PC into.

With WiFi syncing and iCloud syncing, there are very few reasons left to ever plug your iPad into your computer.

Yep, apple included not only an ac adapter, but also wifi syncing.

With wifi syncing, there is no need to connect to either a pc or mac, which don't provide enough power for the current or future iphone/ipod touch/ipad.

2 amps is a LOT of current. It only takes milliamps to kill a person. Of course the voltage would need to be higher, but still.. 2A.


A lot higher. Honestly I've no idea why people harp on about it takes milliamps to kill. Virtually everything you come across in life produces in excess of the 30mA that it apparently takes to kill you.

Yeh Apple doesn't care about PC owners, they care about the user experience. The wall charger obviously provides the fastest juice so why not take advantage of that? USB was really only meant to provide power for low-usage devices.

JUst plug the damn thing into a wall outlet. Good grief. Apple supplies one with it. Why not use it?

Exactly. Someone might have a case if Apple weren't providing one in the box.
