Also, the battery voltage is irrelevant. All electronic devices use charge pumps, boost or buck converters, and other techniques to regulate the voltage sent to the SoC and other components.
The 835 likely needs less than a volt, though I haven't looked over the datasheet.
There's absolutely no reason you couldn't use a standard 3.7V lithium ion polymer battery to 80% of its stated capacity, every day, for years on end, to run these loads. That's what most users, in fact, do.
For sure. But I said right in my post "bouncing off the thermal governor.":)
I highly doubt your average sized passively cooled phone could continuously dissipate more than 2-3W staying below the core temperature limit.
2-3W for 16 hours.. plus radios.. ok, that's still an enormous battery. But 12,000mAh would get close, I suspect.
And, lithium ion polymer is one of the least finnicky chemistries on the market! The discharge curve is well documented and incredibly linear. Discharging 80% reduces the cycle life by little more than what you'd expect, scaling linearly, and the internal resistance doesn't significantly rise until 90% DoD. Permanent damage doesn't occur until discharge below 3V, which would never happen under even 1/4C load @ 90% DoD.
First, differential thermometers can be used to compensate for internal device heat, to some extent. Simply thermally isolate one thermometer, and not the other (ie. one on the screen, and one fused to the chassis). The difference is proportional to the amount of internally generated heat/temperature of the device. Even use of the current sensor over time can be used to roughly compensate.
Second, a thermometer in your pocket is working perfectly. It's telling you the temperature of your pocket.:)
If you want to know the temperature of the inside of your tent, room, or outdoors, you need to leave the device exposed to those conditions until it stabilizes. This is true for all non-infrared thermometers.
The trick is in careful thermal isolation, compensation, and use.
Actually, the V20 does come very close. It tempted me, and I'm really just waiting for ZeroLemon to release a ~10Ah battery/case, and for xposed to drop on N.
As for the battery weighing 10lbs for such battery life, though... not true. My Note 3 with its (zerolemon) 10Ah cell lasts about 3 days idle, or 12 hours with the CPUs pegged, all radios on (though not necessarily tramitting at full bandwidth). With all the power efficiency gains on modern CPUs in the last few years, I'm sure 16 hours would be acheivable.
I have a lot of money to spend on a device, since I only do so every 4 or 5 years.
Could some "brave" soul please take a break from curving displays, gluing batteries, and adding bling to their phones, and address my market segment?
I really want to give someone my money.
For it, you will need to build a device that:
- Has a user-swappable battery, preferably with an ultracap allowing hot replacement. It's not really a hard to do.
- Is too thick. I want pundits to reel. I want trash talk. "What kind of fashionista would buy this?"
- Lasts 48 hours on a charge most days, and cannot self-discharge within 16 hours with all radios active and CPU bouncing off the thermal governor
- Speaks all radio protocols fluently, with dual sim support
- Is IP67
- Has a barometer, thermometer, hygrometer, full IMU with a razor sharp compass, GPS and GLONASS
- Has both USB-C and MicroUSB on the bottom
- Has great speakers
- Has 4gb or 6gb RAM, and the best CPU currently available
- No onboard storage.. just two raid1 MicroSD card slots with a battery-backed memory buffer
Name your price. Since I don't let carriers leach my money away on phone contracts, nor do I toss out my phone every year, I (and a sizable market of people like me) have a lot of money to spend on a truly flagship device.
The main advantage of a removable battery is that it is easier to replace when it is worn out.
A critical advantage, for sure.
But don't overlook being able to easily swap the battery for a much larger one with a TPU (or better) case. I will never own a phone with a battery under 10,000mAh again, because I quite prefer having a big, heavy phone. I know it's on my person. To me, that's important.
I'm a tiny market, but that's the point of user-replaceable shit.
Virtually every top comment is a victim-blaming shitfest.
"Ooooh CRIME he's a hacker! Arrest the victim!"
"Every security expert encrypts every piece of technology they own regardless of circumstances! It's his own fault!"
".. and they ALWAYS take every possession with them everywhere they go, and never lock anything in their vehicle, because they're infallible! Clearly he's not an expert!"
At least modern PCs truly are better; they're almost always faster, cooler, quieter, consuming less energy, etc.
Whereas, I'm still using a Note 3 with CM13. While I am quite happy with the performance, I would like a better camera with manual controls and more RAM. But there's nothing I can upgrade to without sacrificing something.
As far as I can tell, the Note 3 was the last device made with a removable battery, MicroSD slot, temperature, humidity and barometric pressure sensors, AMOLED screen, 10,000mAH battery compatibility (ZeroLemon), GPS and a full 9dof IMU package. Some new phones came close (the v20 tempted me) but lacked a few of these features I use every day.
I fear that once this phone dies, I'll just have to find a used one on eBay to replace it with. The frustrating part is that I have no budget on this one; I'd pay $2000 to get a state of the art replacement that "does it all" and upgrades the CPU, camera, storage, etc.
Blind people, through necessity, can develop mental abilities that seem superhuman like echolocation and rapid aural comprehension, being born blind doesn't seem to be a factor but losing your sight whilst still young is, which is in line with Neuroplasticity. Naturally this is in response to some kind of trauma that renders part of the brain useless without anything to do, and so it rewires itself.
The keyword you're missing here is some. Some blind people can develop mental abilities that seem "superhuman."
And therein lines the problem. Some is not all, and that is the OP's point. We need to find ways to accommodate those who cannot be trained to enter STEM careers.

And one more while I'm nit-picking.. haha.
There's no need to balance cells that are in parallel.. only those in serial. Cells in parallel are, by definition, voltage-balanced.
Also, the battery voltage is irrelevant. All electronic devices use charge pumps, boost or buck converters, and other techniques to regulate the voltage sent to the SoC and other components.

and worries about the acrimonious relationship between the intelligence community and President Donald Trump
As a member of the intelligents community, I feel the same way!
Hit submit too quickly.
Just for reference, I have 3 thermal sensors on the table right now, and they read the following:
- Suunto Alu watch: 24C
- Standard mercury weather thermometer: ~24C
- Note 3: 23.8C
Good enough for me.
Not true at all.

I use the thermometer on my Note 3 all the time.
Memory-backed microSD storage is significantly faster than NAND storage in all but edge-case scenarios.
RAID-1 array of microSD cards is significantly more reliable than NAND storage.
Seriously dude or dudette, what are you smoking?
You're probably right. Sigh.
The OnePlus 3+ looks good, but fails in the most fundamental way: they glued the battery in. :(

As it stands, this is not all that different from hurling a mallet or brick out over a crowd "just for a bit of fun"
Hyperbole much?

The real magic is in letting users choose their battery capacity by installing extended batteries with larger TPU cases.
What the actual fuck is wrong with phone manufacturers these days?
Make a device with a mid-sized stock removable battery. Sell an upgraded battery/case on your web site.
All markets: serviced.
This is not rocket science. These ideas are not new.

Ugh.
I've got upwards of $1000USD to spend on my next phone. It will not be spent on any device which has a battery glued in.
Wany my money, Samsung? Stop gluing batteries into your flagship phones.
Yep. And if anything, it's getting worse.

Open source is always better than closed source.
I mean, it's not even worth arguing. You have one more vector of insight into what's happening.
Compiled binaries can be corrupted, and you can end up with a compromised compiler, kernel, or even, theoretically, hardware.
Nevertheless, open source software is always more trustworthy (assuming equal stated functionality, of course).
Proprietary, closed source: score zero. You have literally no idea, and no way of investigating. You operate on total faith.
Open source software: score not-zero. You have a chance at achieving security. You operate on as much faith as you feel comfortable with.
The Whatsapp client is proprietary and closed source.
It should be assumed to be compromised regardless of what anyone says about it.
That whole reality distortion field thing? You know, that thing that led to Steve Jobs' death from a treatable disease?
Yeah. Your customers ... they don't have that.
Making a product worse is not going to help your sales.
Here's a novel idea: walk away from that junk and forget about it forever. Get 30 hours per week of your life back.
30 hours a week to do what? The things you personally like to do?
Of course, the big question is: will they be smart enough to keep the user-replaceable battery?
Now that Apple has invented bluetooth, am I in any danger of losing my 5 year old bluetooth headphones in a patent dispute? :p
Looks like someone's cheque bounced, and the CRTC ain't happy about it.
