Late to the thread but to share my experiences with my 930, it is overwhelmingly positive.
My phone has been off the charger since 7:05am this morning. I used it for several jobs at work with taking photos of vehicles and building site inspections for signage. I use Cortana on a regular basis to check news and information I like. I have had multiple verbal texts received and sent through Cortana, read through MSN New app a couple of times, shared two news reports on Facebook.....
.... Plus my Birthday and stuff from back home in Canada were coming through constantly today through the Facebook App and Messenger app.
Played a few games through my SNES emulator and Airport City with my son.
Posted several times through these forums and the WMPU forums.... Checked some YouTube Videos and more.
Very regular usage for me on a daily basis.
It is now 10:30pm and my battery is currently at 45%.
Other days I use PC Remote for playing videos through my notebook linked to my living room TV... Or I connect to my PC upstairs through MS's Remote Desktop app to copy files to downstairs or to check on Steam Downloads.
Since the Denim update the battery has been quite good and it was pretty good on Cyan.
The battery is lasting far longer than my 925's.
Despite not having Glance, the 20MP camera, surround sound 4K video recording, 32GB storage, 2GB or RAM, Hey Cortana, etc etc.... And the Wireless Charging if you want that, all far outweigh any minor disadvantages.
If people are having battery issues, turn off some background apps you don't need running like Game notifications, synchronization with OneDrive, etc.
Of course if you play graphically intensive games for a long time, the battery will die quickly, but that's the same with any phone.
The ones that have a longer battery life than the 930 tend to have less guts which cause lag or slow loading times and the battery lasting difference is probably like 30mins to and hour tops.
The 930 is a great phone to choose from in the Lumia line. Good size, good performance, adequate battery, lots of features.... The closest thing is the 1520, but is far more expensive, a bit older and some are put off on the size.
The 1020 has the superior camera out of all the Lumias but is even more dated and it's hardware specs are starting to show its age.
I first owned a Lumia 800, then moved to the 925. While I was impressed with the 925 (Takes the best low light shots I have ever seen) the 930 is just a massive improvement over the 925 in almost ever way except the low light shots. The 930 takes decent night shots but has some grain issues while most of the 925 shots I took were almost perfect.
But I have not regretted getting my 930 ever.
I have used extensively the Lumia 800, Lumia 925, Lumia 625, Lumia 1320, Lumia 1020 and the Lumia 630.... Out of all of these, the 930 is my favorite.
You will have to charge it when you head to bed and every couple of days you may have to charge it earlier in the day if you did more than average that day, but it does charge fast and hasn't put me in a bad spot yet.
For the record, Hey Cortana, Location and WiFi are always on.
