Battery definitely drains faster with any wifi use (remote or via phone). Seems to heat up the camera body more too. Noticed it's more prone to fogging when in the waterproof housing due to the heat. Also worth mentioning that the wifi feature is borderline useless in and around the water. Repetitive testing has shown that if either the camera or the remote dip below the surface of the water for more than a couple of seconds, the signal is lost. Still a useful tool. Just more limited than originally had hoped.

@valpopando You dont want i-anything if you are looking for reasonably priced options but an android phone instead. Any model with wifi and decent touchscreen will do.

Or bungie jumping... nah... too old :(

@trevmar...ah, I believe the assertion is the title of the article....and the history of gopro. Both the A5S and A7 ambarella's are being used in the Hero3. Makes perfect sense that this will be the next version chip inside the Hero4. As for the advantage of double exposure HDR , remains to be seen , but it must make some difference or else they wouldn't be selling it. The assertion of this going into a new gopro with a new lens comes from gopro doing the same thing with the Hero3. 4K will require a better lens ...maybe even a set of lenses. To quote -

I came away very impressed with the resulting video quality, clearly the age of 4K/UHD is upon us with the availability of inexpensive encoders like these that will make their way into small form factor cameras.

I wouldn't be surprised to see a GoPro Hero 3 Black successor with the A9 SoC inside and those higher framerate capture modes fully enabled at some point in the very near future since the A9 SoC is now available to customers.

yep....you're missing hdr at 1080/60p...you're missing 1080/120p.....and 720/240p...and you're missing the idea that this will be put into a completely redesigned package....with a new lens .

ya'll might find this very interesting ....

POWER SUPPLY AND HEATING ISSUES with Black and 64GB memory cards

I tore apart a cheap Hero3 battery in order to get a plastic housing that would plug into the back of my Black and allow me to feed it directly with a stabilized power supply instead of via a 5V USB supply. The resultant maximum front panel temperature dropped from 63 to 55 centigrade when recording 2.7K cin, 24T with the latest software.

Cards which consistently failed to span when the Black was fed from a 5V USB supply, and the front panel reached over 60 degrees C, will now fill without failure. Have been running tests in a Frame, on repetitive 3-hour cycles (3 hours is the maximum capacity of the card, and also the energy in one of my GH2 / FZ200 batteries (BLC12) powering the whole caboodle...

Interesting...

@trevmar The issue I was having was the sequence of turning the camera and battery on. If I turned the battery on before the camera, the camera would instantly lock up. It was fine the other way around. Haven't messed with it much since the update, since the D7100 ACR update came the same day. :3

I've had 2x 64GB Sandisk Ultras since launch and no problems with them. No real problems with the cameras, either, beyond the old locking up in low light in photo mode, and some hiccups with external power.

@trevmar Forgot to mention that I use protune as well 2.7-no problems before and after update. That was just a test I use battery pack if need full card recorded - handier but thanks for advice.

@konjow The problem occurs most with Protune. I was using 24T 2.7K. If you connect a 1 amp USB charger (such as an Apple iPad or the GoPro chargers) then you will be able to record the whole of the card.
