Then again, they expect those customers to spend $5K on a new computer. So clearly they are idiots. that $5k is for a system that *starts* with an 8 core xeon processor, configurable up to *18* cores, 10 gigabit ethernet port, an internal 5k wide gamut display and can also drive *two* *more* external 5k displays in addition to the internal one. that don't come cheap. not everyone needs that level of power, and there are less expensive options, from apple and others. So... you're in AppleLand now. Don't worry about thinking. Don't anticipate problems. Just enjoy the magic....

I'm not "claiming" it is draining the battery, but am asking why the battery is not increasing in use because the camera is recording that extra 1.5 seconds at all times when that mode is on. because it's not recording anything unless you actually take a photo. the live preview, which occurs any time the camera app is open, is buffered in memory for autofocus, autoexposure, face detection, special effects and much more, whether or not live photos is on or off. if live photos is off, just the photo is saved to flash. if live photos is on, then the photo plus the last 1.5 seconds of the memory buffer is saved, plus the following 1.5 seconds unless the camera moved enough to where the video is no longer relevant. {*] even if you don't take any photos at all, the phone is still using power to run the camera app, get data from the sensor, display it on the screen, etc. the amount of power to write a file to flash, even if the file is slightly bigger when it contains video, is negligible compared to everything else that's going on. * when live photos first came out, there were a lot of live photos that ended with video of people's feet, the sky, the inside of their pocket, etc., because people put the phone away after taking the photo, so the phone now checks for that happening and if it does, it stops saving video. |

Seems like it would run down the battery if one wasn't careful to turn off Live Photos when not expecting to use it. I suspect it uses the usual clever tricks to determine whether you are about to take a photo (camera app open, in-app option visible to the user to activate, motion processing that indicates a photo taking posture and so on) so the additional power draw is not all that much. If the meat and bones of the function is in hardware (GPU) rather than s/w then the additional power draw could be dramatically lower, as well. Further, the temporary images would be written to RAM, not flash, so not much power is needed. Like most features, when it's active, more power is being used - but there are always strategies (some above) to minimize that draw. Apple have been pushing a lot of features to hardware when possible. This improves both performance and energy use. -- "If war is God's way of teaching Americans geography, then recession is His way of teaching everyone a little economics." ..Raj Patel, The Value of Nothing. |

The HomePod is larger than the other two which allows for a larger subwoofer. it also has seven tweeters. No one has been able to report on it's sound quality yet but I expect it to be better than either the Echo or Google Home. If it's worth almost three times the price of the Google Home or double the price of the Echo is a question for the user to answer. Microsoft's Cortana enabled device is made by Harman Kardon and I expect it to have superior sound qaulity to the Echo and Goold Home just as the HomePod will. It most likely will have a price closer to the HomePod. Amazon allows the smart assistant to be used by third party manufacturers and there are thousands of "skills" it has. It has a leg up on all the other assistants because of that. We all know how much of a "closed" system the HomePod will be so it remains to be seen how fast the functionality of the HomePod can even come close to an Echo or Google Home.

Andreas Skitsnack: If Live Photos is a mode that can be turned on or off, it would seem that this adds battery drain when it is on. Yes or no? no. there is no reason why it would. I'm not "claiming" it is draining the battery, but am asking why the battery is not increasing in use because the camera is recording that extra 1.5 seconds at all times when that mode is on. Obviously live photo takes more battery power than not using it - from the assumption that if you turn it off, the buffer isn't used at all. When the camera app is active, the camera sensor is being read from and is being displayed live on the display. The iPhone 7 Plus display is 2 megapixels, so obviously the entire camera sensor image is not streamed as-is to the screen, it's a scaled-down version. The buffer contains 3 seconds of 12 megapixel images. It captures these at 15 fps, so you get a total of 45 12MP images when taking one shot. Obviously, buffering and saving 45 12MP images takes processing power which in turn consumes battery (and storage space). I would assume that this is very marginal though, and like I said, it assumes that this buffer isn't always used even when the user elects these images not to be saved, which it could be, if the user has turned live photos OFF and the buffer is still there, the camera app could do a quick analysis of the buffer to select the least blurry photo for instance, which may have been four frames before (or after) the user actually pressed the shutter button. In that case, there would be no difference other than in storage space. -- Sandman |
