I have discovered a major issue with mine from last night
No new apps or sync loaded and battery drain is ridiculous just timed it and 25% in less than an hour....plus the phone is heating up dramatically
My wife's phone is exactly the same build and version with no issues....
I have a problem that I am out of the U.K. Now for two weeks and need a workable useable phone
Any advice help would be very much appreciated....
As I write this another 3% has vanished,
Tried reboots etc...no good

My advise may be late, but don't install a beta software on a phone if you know you are going abroad and need a workable useable phone...
Ps. Did you tried to switch a low power mode on?
Has anyone tried rotating safari tab view with 3 or 4 tabs? Is it me or it's glitchy ****ing whore.
9.3.2 beta 4 is giving me great battery life and a more than smooth enough user experience compared to 9.3 and 9.3.1. So if I chose to stay on this version, will I eventually get a message like "beta expired" and be forced to update to a new beta or the official release? I´ve read that this has happened to earlier iOS betas but haven't read anyone encountering it on the 9.3 beta-cycle.
noticed a strange problem on the new beta. Usually iOS doesn't drain battery when on standby. beta 3 in particular was stellar . On beta 4 with low battery on there was a drain of 25 % overnight on my 6 plus . When I checked battery life the major offenders were spark for email and whatsapp. However background refresh is turned off during low battery mode , so not sure what happened. Funnily enough I went from 100 - 55% after an entire day of heavy use on my 6 plus , but it drained 30 % overnight when on standby.
Before public beta cycles. Every beta had an expiration date inside. After that date the device was turning back to activation screen and stuck in there. But after public beta cycles. This ''certificate'' situation is finished. It's working like final releases, update when you want. I didn't hear about any problem with this. But when final versions are released, you better update your device to these fw's. If 9.3.2 final will be identical with b4. You continue to use that fw.

Kernel & iBoot versions change is the true update in this bug fix point update.
Simple, by digging out xtract (.ipsw) and xcode utilities, provided by Apple.
good. beta 4 is much better than any final release of iOS 9, kernel change is the main impact i think.
Secure boot chain
Each step of the startup process contains components that are cryptographically signed by Apple to ensure integrity and that proceed only after verifying the chain of trust. This includes the bootloaders, kernel, kernel extensions, and baseband firmware.
When an iOS device is turned on, its application processor immediately executes code from read-only memory known as the Boot ROM. This immutable code, known as the hardware root of trust, is laid down during chip fabrication, and is implicitly trusted. The Boot ROM code contains the Apple Root CA public key, which is used to verify that the Low-Level Bootloader (LLB) is signed by Apple before allowing it to load. This is the first step in the chain of trust where each step ensures that the next is signed by Apple. When the LLB finishes its tasks, it verifies and runs the next-stage bootloader, iBoot, which in turn verifies and runs the iOS kernel.
This secure boot chain helps ensure that the lowest levels of software are not tampered with and allows iOS to run only on validated Apple devices.
For devices with cellular access, the baseband subsystem also utilizes its own similar process of secure booting with signed software and keys verified by the baseband processor.
For devices with an A7 or later A-series processor, the Secure Enclave coprocessor also utilizes a secure boot process that ensures its separate software is verified and signed by Apple.
If one step of this boot process is unable to load or verify the next process, startup is stopped and the device displays the “Connect to iTunes” screen. This is called recovery mode. If the Boot ROM is not able to load or verify LLB, it enters DFU (Device Firmware Upgrade) mode. In both cases, the device must be connected to iTunes via USB and restored to factory default settings.
Low-Level bootloader ~ iBoot ~ Kernel
This way the Key Component is iBoot Version update which in turn renders iOS Kernel Mode changes properly.

Exactly the same issue, I thought it was only my phone. I never ever complain about battery life and always rave about my battery life being so good but my iPhone 6plus heating up like crazy when not even doing anything but browsing and my battery dropped from 95% to 44% whilst on standby and not being used at all. Then it drained to 10% in about an hour and then phone died at 10% when I restarted phone it was automatically at 6%.
Something really weird is going on with the battery in this build for me. Battery in settings is also showing nothing unusual which makes me suspect the OS.
wow thank you for that great explanation
i'm waiting impatiently for 9.3.2 just hoping more performance. stutter free animations etc.

I'm grateful to you for your admiration. Mr. Makale.Helvetia, you are a reasonable person that's why i explained you every concerned level in details without waiting of your asking for.
In my personal opinion that we all should be obliged by the limitations of the topic scope, rather than going off limits as it happens in the case of Apple's business going down or up.
Why we are concerned with the off topic and out of perspective approach towards irrelevant issues while we have to focus upon the relevant things?
our expectations are so high..because..Apple = Stability for us..that's the answer.. we dream about ''Steve Jobs Era'' but thing are really changed after his death. i don't remember so many people complain about softwares and iDevices. now we are driving through a different way with ''Tim Cook Era'' and i'm not sure i'll try iOS 10, i'll stop on the most stable release of iOS 9. probably this one. and i think the final release of 9.3.2 will be identical with beta 4.
Since Steve jobs era, many more Idevices, more internet users, more people on betas, all amounts to more noise on the inter webs.

Who's a troll?
He uses reduced motion. With that enabled, the icons on the home screen don't use the parallax effect so they're obviously aren't going to move when he closes Notification Center
