AT&T Lumias get reduced battery life estimates

Last month we saw the announcement of the new Lumia 920 and 820. Back then, there was some concern for the 920's battery life. Having such a big screen, HD resolution, a dual core processor, not to mention LTE, it really needed a powerful battery to keep it going through the day. The 2000 mAh that it came with seemed to be the perfect match.

Nokia touted 10 hours talk time over 3G with 400 hours in standby mode. Playing music would also get you about 67 hours of uninterrupted listening. However the AT&T version has downgraded  battery time estimates. According to the product page, the 920 only gets you 320 hours of standby, 9 hours of talking and only 52 hours of music. The same goes true for the 820, that also lost a few hours here and there.

The reason for the change in specs is unknown. It could be that after carrier testing AT&T asked Nokia to tune their firmware in some way resulting in less battery juice. Or it could just be that Nokia and AT&T are using different tests and different standards. What's even more interesting is that the international versions of the phones still retain their initial specs as you can see on Nokia's product page.

Of course there's even a chance that these AT&T specs will be revised again when we get closer to the launch.

/QUOTE off front page :
The Lumia 920 and 820 that are heading to AT&T have had their battery estimates slashed.

Hardly 'slashed' are they??

Get a grip

A thick, big and heavy phone like this should do better with battery. You have to wonder about the technology inside.

2,000mAH is not a big battery anymore, I would like at least 2500mAH. I would much rather have a slightly thicker phone with a much larger battery over a slightly more thin phone but with a much smaller battery. For me 2-3mm in thickness really doesn't maker a difference anymore, all the new phones are think, but that 2-3mm difference can make a huge difference in battery size.

The damn phone is already super thick and heavy for something its size. I wonder what they stuffed in there that they couldn't have made the battery fit in it. A phone that thick should easily fit a 2500mAh battery.

LOL! So was there any truth to the whole Lumia 920 unveiling? Seems like everything has been a lie so far..

There's this biiiiiiig long body of text at the top of this page called an "article". It has words and sentences and information in it. Go try reading it.

I think the real reason for the reduction is that North American LTE is pretty much standardized on Huawei radio equipment which is not the gear Nokia designed the phone to work with. As such there is more compute (battery) required to establish and maintain a signal.

Most likely the additional AT&T bloatware using more juice.

Very possible. I played with an AT&T Lumia a while ago and their software was borderline nuisance... I wouldn't be surprised if it used more...

Luckily, all software can be easily removed with Windows Phone, so getting rid of the AT&T apps is a snap.

How so? They can't have their programs run in the background without user permission and all pre-installed apps on WP can be removed by the user.

It looks so thin in the advertising, but looked so fat in that french video

Have you held the Lumia 900? If so then theres no worry. The fat body falls perfectly in the hand. And the Glossy finish feels great! (held a white one)

You know as they say, the camera adds 10 pounds

The fact is, the 920 (10.7 mm) is thinner than both the Lumia 900 (11.5 mm) and the Lumia 800 (12.1 mm). I have the 800 and it isn't too thick at all. It feels very good in the hand.

I don't care about AT&T, i'm going to buy international unlocked version !

If you're on AT&T then that's just dumb. You'll pay more and won't get LTE. If you're not on AT&T then why WOULD you buy the AT&T version?

It takes more battery when searching for signal and redialing after all the dropped calls

i think your talking about sprint not at&t.

Well, maybe they found a successor for "CarrierIQ"?

Ahh, CarrierIQ. Another thing everyone on the internet hates and nobody on the internet understands.
