Been on 100% all day... Not sure if broken or just amazing battery life lol
I think the percentage algorithm may be a bit off. The percentage decrease speeds up throughout the day for me but still great battery life. May be related to the addition of Low Power Mode.

Very impressed with the battery life. The difference between Beta 1 and Beta 2 is night and day. Today I put my phone on charge since installing Beta 2 on release day. Here's my results:

I must admit however, I didn't use the phone as much as I usually do, but still the battery life is impressive. The new Low Power Mode wasn't used either. Initially I thought the battery percentage was miscalculating and not going down as mentioned earlier in the thread but its fulfilled the hours shown in the screenshot.

Phone: iPhone 6 Plus

I stopped doing OTA updates for iOS many moons ago. I always download the firmware and alt+click "check for update" in iTunes and pick the firmware file. Apart from battery issues in beta 1 I've not experienced any of the issues.
Add me to that club as well. I've heard way too many bad stories about OTA updates.
That's my method, as well. It's worked well in the past for me and I'm doing the same with beta 2 right now.
FWIW, I adopted a modified version of this a couple of years ago - although I completely agree with your MO here.

In the case of my iPad 3, with the clean B1 and OTA B2, if the first beta seems pretty solid I'll keep it, then test the OTA. If the OTA seems pretty solid too, then I'll use that for 2-3 days while I test out my apps. Then, after those 2-3 days, I'll perform a clean install of the newer beta with no restoring from a back up. If the newer beta seems to bork anything right away, I'll first attempt a "reset all settings" and/or perform a clean install sooner - either way I test a clean install regardless of the OTA.

I also performed a clean install of B2 on my test iPhone 6 - performance is much improved, with a couple of caveats. I noted that some of my account information was present in the "clean install" - I have different iCloud accounts for my workflow (main account) and App accounts (iTS/App), and saw that the clean install did not wipe the user account names from the relevant fields. Next, my iPhone 6 had some issues waking up after some light use - Siri wouldn't start, pressing the Home or Power buttons lit the screen but wouldn't provide me with a usable screen, and TouchID wouldn't work; I powered down the device and the Power button wouldn't turn on the device - only inserting the Lightning cable woke the device. I'll be submitting a bug report for this - FYI; the device was fully charged, had been used for data and calls, and was not warm to the touch.

I've been using the OTA updates ever since they were available in beta and never had any issues with my phones. Most of the times I usually do a Reset All Settings after a new beta version in order to eliminate any bugs. It's served me well so far.

iPhone 6 iOS 9 Beta 2: I'm experiencing better battery life than iOS 8. I've been using my phone all day. Intentionally trying to run it down and it's much higher than I'm used to.

Don't have specific numbers, but after a few day's usage, battery life on my iPad Air 2 and iPhone 6 Plus actually seems to be better than it was even on iOS 8 (which was great for me). Very happy with this beta in terms of the performance increase and battery life, compared to beta 1.

Now if only Watch OS 2 would get it together. My Apple Watch is basically useless as it's constantly freezing and won't do dictation, even after erasing it and setting it up as new.

looks like Beta 2 is good with battery!
And if we compare it with beta 1, the battery life is just like going from hell to heaven.
Every beta tester, whether dev or not, is greatly inspired by the great improvement of battery life.

Maybe, your watch needs the next beta, maybe.
PS: I still think Apple Watch is super expensive.

Why don't you have a backup?
Because I solely relies on iCloud backup, and neither iCloud backup nor iTunes backup can backup "full application data", which I thought they could do. Some application data may be backed up to iCloud, but iTunes would not backup it.
Now, iCloud backup is broken, therefore I cannot do any kind of software update or restore if it will surely destroy my data. I cannot afford losing them.

This is why I use encrypted backups in iTunes. iCloud encrypts your backups by default but not iTunes. If you encrypt your iTunes backup, it'll store more data from your device.
