Shouldn't Wi-fi model have much better battery life than 3G/4G models?

I am not an engineer, but I was just wondering...


Shouldn't Wi-fi model have much better battery life than LTE ones?

Because LTE is a battery killer, but I only have Wi-fi models. Shouldn't Wi-fi ones have much much battery life than LTE?

LTE now gets 9 hours and Wi-fi gets 10 hours.

Is this accurate?

Better LTE radios use less power than previous LTE radios.

I was wondering the same thing. I'm not an engineer but it sounds probable to me.

Sure, if one was to only use 3G/4G/LTE their battery life would not be as good.

However, if cellular data was turned off, as mine is, their battery life would be just as good.

The screen is the biggest power sucker, so that's why the numbers are so close.

This is what I was going to say. Some place claimed it used twice as many led's for the backlight.

I think it's because the main drain on the battery now is the retina display and a5x chip, but when I first saw the keynote I was surprised that the bigger battery meant there was not a small increase in battery life for the wifi model I expected the 4g to have the same as the 3G iPad 2.

Only time a LTE might use more power is while on LTE. I have LTE but have yet to have the need to use LTE. The day will come, it has before and I will be glad I got it.
