It's slightly worse for me, but nothing drastic as you are describing. I am also using my iPhone ALL the time now, playing with the new UI, and still am getting through most of a work day with 20% remaining. I'm using an iPhone 5.
 
It seems about the same, to me. Or at least, so close that I can't tell?

Especially since I'm playing around with it more, since updating to the beta.
 
Why is this so surprising to you guys? It's the first developer beta...

It's not a public release so this shouldn't be surprising.
 
My 4S is embarrasing at the minute since I upgraded. It's probably one of those early beta things, Beta 2 or 3 will likely sort it.
 
I tested this today and purposefully didn't charge my 5 while using it. I got 5 hours and 55 minutes of usage with mostly using LTE, streaming radio, visiting websites, refreshing Tweetbot and some gaming. That's about the same I was getting with iOS 6.
 
After just 1 hours 43 minutes after a full charge I've just 16% left in my battery.

It was never this bad with the previous beta that I tried.

It's a beta. You're a dev, you should know this and be running it on a test device for the strict purpose of updating your applications for iOS 7.

I can understand that. It's just the degree of the problem that took me by surprise. I wonder if that's primarily due to the different multitasking design.

I've already switched off location services, data, LTE, background update, and Bluetooth. I'm primarily just listening to music and checking Facebook occasionally in my test.
 
Did you restore from an iCloud backup? That will severely drain your battery until it finishes. If you, like me, have tons of photos and media, that can take days.
 
Are we sure the iPhone isn't just indexing the contents because a new OS was just loaded onto itself? This returning to normal in due time?
 
Literally losing 20% of the battery life in an hour with no apps running and very minimal use (no calls), the phones VERY warm too - I hope they can fix this or it's a dead duck.

r u using the iphone 5??

It's simply because it's a beta. Apple doesn't intend for it to be used on a device daily I would think so it's likely not the top priority over bug fixes. Plus, there's probably extra things running like debug code and diagnostic stuff because it's a beta. There also could be bugs with new features that are causing the drain. There's a reason they have betas.

Please know that I'm not one of those people who hates non-devs using betas. I'm merely pointing out that the reason the beta has bad battery life is because it's a beta and there are still things to be worked out.

This reply makes a lot of sense. Thank you.
 
In my opinion the battery drained slower over the night on iPhone 5. Around 4%, on iOS 6 was sometimes 20%. If I use the phone i have the feeling it drains quicker.
I would recommend to look on location services, especially system services. There are couple things that like to use it a lot.
Also wallpaper motion tends to use more cpu power, so it would be nice if there will be a option to turn that off later on.

I've turned mine off and I'm hopeful it'll make a difference.
