Don't worry abotu what people say here. Most people have no idea what they are talking about.
3150 mAH is perfectly usable.
Consider the HTC HD2 has a 1250 mAH, 1 Ghz processor, 500 mb ram, 800x480 display. That lasts about 4.5 hours of continuous usage of surfing over 3G with a couple things running in background.
Reading an eBook with display at 60% brightness (ideally you should set it even lower for confort), the 1250mAH battery can last around 8 hours.
That's a 1250mAH battery powering the same MHZ processor, same resolution, similar RAM. 3150mAH is more than enough to last 10 hours. If I had that capacity ini my HD2, I'm sure it'll power my device for at least 14 hours of heavy use.
@ounkeo Not really a good comparison as the 1 GHz Cortex A9 is a very different processor than the Snapdragon (which is has roots in Cortex A8 but is really a custom-built CPU).
What it does illustrate however is a worst-case scenario. The 1 GHz Cortex A9 is not only more power efficient than the Snapdragon (and performs significantly better), but assuming it's a 45 nm chip (a de-facto standard for Cortex A9 unless I'm mistaken), it's going to be about 20-30% more power efficient than the 65 nm Snapdragon.
The new FiOS HD DVR, arguably the biggest update since Verizon released a DVR, thanks to its external storage support, enhanced multi-room functionality and slick new 16x9 HD user interface.

so is a 3150 mAh battery good or bad? pls enlighten me coz there seems to be alot of remarks regarding the battery
@tcdmagic Seems decent to me, as most smartphones have a battery capacity of about 1000-1500mah...
@tcdmagic well without any specs on how much power the device consumes mAh is really a meaningless number
@tcdmagic In fact, I'd be surprised if the iPad's is any bigger (than Aigo's)...
@SlimSpaceman The link claims 11.5 W, but I'll assume it's W-h (11.5 watts is laptop territory), compared to 25 W-h on the iPad.

@ounkeo "Most people have no idea what they are talking about."
And what about the display size?

@Jacob1 The iPad specs list the same thing:
"Built-in 25-watt-hour rechargeable lithium-polymer battery"
