My Motorola X Force last a good 3 days on the one charge. Granted, I'm not playing games or watching video 24/7, but even then it's supposed to last a whole day.

What am I doing wrong?

My cheapo ZTE used to last 10 to 14 days when it was new. It's coming up to 3 years old now and I'm worrying I might have to get a new battery soon because it's down to only 5 days.

Now, since there are potentially way over hundreds of thousands of bats in a large cave, you can maybe do some damage with a portable transmitter targeting all of them individually...

Only if you put white tape around the edge of the wings.

Too loud for humans, problematic for wildlife, steerable phased array already hashed out... Methinks if she is truly clever she will talk to airports about bird control. A demo remote vehicle with it on it, 2 phased arrays running 5-10khz apart so the beat frequency is audible (have seen a demo of this before on tv) and it could potentially be an idea actually worth 30M

I'm not sure a 2KW airport bird scarer with a range of 4 meters would be all that useful. :)

If there was a wearable version you could eat chips at the seaside in peace.  :)
Anybody got a syringe I can use to squeeze the magic smoke back into this?

Unrelated to the topic, but a new (original) battery is usually recommended for old devices. If you've gone over 300 charge cycles you've probably already worn it down. Especially with cheap brands: I've had Samsung last 4-500 cycles, Huawei 2-300, Xiaocai ~200. I've just replaced my battery on my old Motorola XT910, bought mid-2012, was down to 1000mAh from 1800.
Other than that, technology evolves, I get 1.5%/h battery loss on my old phones versus 0.3-0.5 on the latest-gen ones. Apple wins hands-down, don't know how they do it. As a tech guy I'm impressed, but much less about their prices...

On topic: I would normally ignore any free-energy and wireless-energy bullshit, but 90% of my friends believe in that shit if it's packed in a nice video. So it's nice if someone takes a stand, because more opinions make a change.


Ok, so we have the BigPharma conspiracy against natrium chloride panacea, BigOil against free energy, now it should be BigEE against wireless energy?
Pronounced "biggie", of course.

At least, if not as power supply,  it can be used by police to control street riots:

Reminds me of this: https://en.wikipedia.org/wiki/Stink_bomb#Range

Quote
At the upper end of the spectrum, the governments of Israel and the United States of America are developing stink bombs for use by their law enforcement agencies and militaries as riot control and area denial weapons. Using stink bombs for these purposes has advantages over traditional riot control agents: unlike pepper spray and tear gas, stink bombs are believed not to be dangerous, and they are effective at low concentrations.

Regarding ultrasound as crowd control, I might have a story about pacifying a drugged-out neighbor turning up his subwoofer loud at 4am, every night/morning. It's incredible what a small Bluetooth speaker and an Android signal generator can do. Unfortunately it's not related to the topic, possibly not legal and likely never happened...

A few years ago, someone had come up with a "crowd control beam" that caused anyone to be hit with it to instantly lose control of their bowels. I don't know what became of it, but talk about the most effective crowd control method ever!

It was a VLF inaudible frequency which vibrated tuned to the average dimensions of your gut with embedded almost audible thumps as well.  If I remember correctly, saw it in a documentary quite some time ago.

Yes, it was something like that, only not using VLF and resonance ("The Brown Note"). It used much higher frequency (that caused the muscles to forcibly contract) and was itself modulated at a lower frequency, which would cause severe abdominal pain and ultimately diarrhea.

I'm not finding much on Google, but I know it's out there somewhere. Just a matter of finding the right keywords...

(I would have named it the pooBeam.)

And stink bombs can be used with it to amplify the effect  :scared:

The "Brown Note": https://en.wikipedia.org/wiki/Brown_note

Disproved by Mythbusters: http://www.discovery.com/tv-shows/mythbusters/mythbusters-database/brown-note/

https://www.dailymotion.com/video/x3ccamo_mythbusters-s03e01-brown-note_webcam

This was something different that used a much higher frequency (sort of like the microwave pain beam that DARPA has tested).

It's an urban legend, sorry.

Perhaps implying that her "starting assumptions" are based on a Separate Reality of laws of physics in a Parallel Universe which we are not privy to.

Well she did say that the starting assumptions are incorrect, but said nothing about the end conclusion!

It seems that my uBeam video has done it's job  ;D

Her complete lack of any form of technical rebuttal is duly noted.
I mean there are so many things I got obviously completely wrong she doesn't know were to start, right?  ::)

She doesn't even seem to realise that a lot of my numbers are pretty much backed up by her own (former) Vice President of Engineering in his very public and quite technical blog posts. So much for "knowing nothing about their technology"  :palm:

This photo is interesting.
Not only because of the PCB array panel of some description (the beam forming array panel?), but look at the whiteboard behind her.
It looks like there are classic design goals, the specs of which are covered up by post-it notes.

https://www.usatoday.com/story/tech/news/2017/06/01/ubeams-meredith-perry-shows-her-stealth-wireless-charging-technology-really-works/102336880/

Why are such basic design goals on a whiteboard after 5 years of development, and when they said they were about to ramp up into production over a year ago?  :-//
Of course based on what they showed recently in a video, yeah, they need massive amounts of work on all of those points.

If that whiteboard was a presentation to USA Today, it makes sense they would be stating the basic goals.

But the thing that stuns me is they actually went out and bought a brand new high-end phone to prove the results were not faked, and then didn't require proof that the "receiving " box attached to the phone did not contain batteries or supercaps.

I have no idea why that box has to be so thick anyway. What is in it?
