Hey guys, I just wanted to share with you the fact that I noticed an improvement with the battery life after the latest update!!
I'm still using it like before. (3G connection always on, social network, blog reading, glance on, sensitive screen, whatsapp and playing few games).
With GDR2+Amber, the battery would have got me to 5pm maximum. Now it's lasting all day from early 8am to 10pm!
I'm realy happy. So is it just me or anyone else is also getting same results?

For me its to soon to give my opinion (cuz my batter is holding sometimes good sometimes bad). I'll wait few days and report.

The fix came with gdr3 developers preview second update, and yes it improves battery very much.

I really can confirm your findings. After the Black/GDR3 update the battery performance of my 920 is really impressive. So I am a happy man. Still using an iPhone 4s though to a minor extent (15%) because not all apps ( definitely banking) are available on WP8. But things are surely improving. Looking forward tot WP8.1 Blue.
