AT&T Nokia Lumia 920 and 820 get slightly reduced battery life

Windows Phone 7 is renowned for being battery-friendly but new features coming with Windows Phone 8 like HD resolution, multi-core chips, etc. are obviously going to demand bigger and better batteries. The Nokia Lumia 920 is also bringing new features such as the PureView camera, Wireless charging and PureMotion HD+ display. All these - including LTE - will need a genuinely big battery for users to truly enjoy a full day's use.
The 2000 mAh that the Nokia Lumia 920 comes with seems like it will be up to the job, but for some unknown reason, AT&T recently posted updated battery specifications which appear to be lesser than the global version. The AT&T Nokia Lumia 920 version has been slightly marked down, most likely due to firmware changes and maybe their super fast LTE network.
The global version of the Lumia 920 is listed as capable of 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. The Lumia 920 is listed as only capable of 320 hours of standby, 9 hours of talking and only 52 hours of music. The same goes for the AT&T Lumia 820, which also has been listed with slightly reduced battery life.
Again, the reason for the downgrade is not known at present but we suppose it could be firmware changes or just be that Nokia and AT&T are using different tests and standards. Whatever it is, are any of our readers worried? Let us know in the comments
