3dEvo: Pre-release miscellany

Just another PS - specs are just specs, they never tell the whole story.

They start to, but the stuff not discussed is huge - and everything discussed in specs by the popular press is pretty much moot.

Example - the DSP core in the Evo's 8650 is clocked at 600 MHz.

Things like that matter, too.

Agreed.

And I believe others agree that the Pre will definitely get above 'slightly warm' when trying to truly multitask (Navigator and text, or calls, or just about anything else, for that matter). I use Navigator alot and would really like a device that I can use GPS without having to worry about the (too many) cards issue, or the silly thing just rebooting like it was a windows device or something... We won't even get into using GPS, while listening to MP3 thru bluetooth. Or trying to that is :mad:.

So bring on the dual core beasties, already!!!

From what I've read, the majority of battery and heat woes associated with GPS can be blamed on the radio/antenna rather than CPU, so I'm not sure a better processor is going to address this. Before Android and iPhones were popular, blackberries already had GPS abilities. But it really, really sucked. Very hard to establish and maintain a connection with the satellites. It was around this time that I read that dedicated GPS units (Magellan, Garmin, etc) give more power to the radio/antenna to ensure a strong connection, whereas if a phone did the same thing, the battery would be drained very quickly. Dedicated GPS units almost always require that you have it plugged in to the car's charger port.

The GPS on the blackberry was practically unusable, so only on paper did the blackberry sound good with its GPS abilities. Apple and Android both decided that if Navigation was something the phone could do, it should do it well. So these days, the phone's radio draws more power, and most definitely, the connection is more stable than my old Blackberry.

iPhone users also complain about poor battery life when using Nav. Case in point:
battery life - Why does GPS on the iPhone use so much power? - Apple - Stack Exchange

But in my experience, Android(my Evo to be specific) uses even more, and consequently, it holds a connection better than the iPhone, verified by my my wife who has an iPhone.

Because I like the nav feature, I spent a lot of time researching a charger that would keep up with the drain. This is not as trivial as you might think. But since I'm getting off topic, I'll spare the details unless you want to know.

And by the way, my search for a charger was what brought me to these forums. And being the noob that I was, I posted in the Moto Droid forums, cause that's where google brought me when I was searching for 1.5mA chargers.
 
Thnx Novoxx! The Palm (not OEM) car charger I have for my Pre keeps up fine, but the phone cannot. For real, sometimes the phone would just lock up when on NAV and trying to text! 2 x yesterday, the phone locked up to the point where I had to pull the batt!:mad: And I've heard too much about the Sammy GPS woes, so I'm kinda scared about the NS4G (tho I've also heard its been "fixed'). So I'm hoping the 3D is within my time contraints and within the budget. Can't see a phone with that much muscle have too much trouble with the stuff I do. :rolleyes:
 
Yeah I think the Evo 3D will work fine multitasking with GPS, since the Evo was fine with it. Only thing I noticed, and I know this is a safety constraint, is that when the battery is hot from using the Nav, and you have the phone charging, the phone will disable the charger when the battery hits a certain temp, around 50C. This is because at these temps, the Li-Ion battery is getting very stressed, and unwanted chemical reactions start to happen that can reduce the capacity of the battery.

When this auto-charge-shutoff occurs, the Nav will continue to work, but obviously now there is a net loss of charge on the battery. So eventually the battery will drain even if the charger has the ability to keep charge. I suspect Evo 3D will be the exact same way.

The remedy: when the phone gets too warm and the charging shuts off, put the phone against an A/C vent and turn on the A/C. Doesn't take long to cool it off. Better yet, if Nav is used often, buy a mount that allows you to fit it over an A/C vent. Now you have a cooling system for the phone and it will never have any issues.

I figured as much. Bummer since 4H is a battery hog :/

3G is quite the hog for me too. I can lose all of my battery within 2 hours in an area of poor 3G reception.

I don't have 4G in my area, so I've never witnessed the drain myself. Is it worse than 3G drain?
 
I can drain it on a few hours of intense internet access, 3G or wifi. 3G in and of itself isn't great compared to wifi, but when used with 3G for just email, occasional web, decent signal area, it seems to last for several hours, not just 2.

I timed it at some point, and don't recall specifics - but the Shift on 3G is better, definitely - suggesting that a 3G radio update in silicon is in the offering for newer units.

I've only used 4G when I've been on travel and was plugged in to a power source, so I'm no help on this one.

Playing spelling Nazi is against the rules, but I just gotta say - if you meant to do that, it's hilarious. ;)
 
yeah, is there an app that quantifies your 3G signal strength? There's no way to do a battery life comparison without this critical info.
 
In regards to power features, it is hard for me to say my personal experiences. I don't live anywhere near 4G (unless you count Chicago, which is 5 hours away close). I have tried it both in Los Angeles and in Chicago. Both times I had 2 bars (out of 4 I think?) and left it on for about four hours. The phone seemed warmer than usual (but it could have been me looking for reasons here LOL) and my battery was down to about 40% or so where it normally would have been 70%+ Now, I say normally, but I don't spend a whole lot of time in either of those cities, so "normally" is a comparison with my home city (which as I said doesn't have 4G). Between my extremely unscientific tests and reports from others, I think it's safe to say that 4G generally drains more battery than 3G. Exactly how much? I can't really say.

What makes it so "S?"
Click to expand...

Lol they're manufactured by Sony but the "S" stands for Super. It produces more vibrant/crisp colors than the regular TFT displays(comparable to that of the oh so "adored" Super-Amoleds" but without the blue tint over everything so you still get true whites. I've done side by sides with the T-Bolt and iPhone 4 and the SLCD is right on par with the Retina in detail, and even better in color. The Retina also suffers from the blue tint that makes everything darker than it truely is, while the SLCD looks more natural and realistic.

Do you have a reliable source that states S = super? Because from what I've heard, that's just a big fat assumption.


-edit-
so I did some digging of my own. and could not find a reliable source stating S = Super in the context of S-LCD. However in the context of display technologies like S-PVA and S-IPS, there seems to be a consensus that the S does stand for super. So I guess it's safe(r) to assume S=super for S-LCD as well....

No. Absolutely not. There may be a consensus for this on the internet thanks to blogs, but it is simply untrue as well as completely false.

The nonsense that S stood for Super was started by Android Central, so far as I know.

I know you've read this.

S-LCDs are used in a lot of TVs and phones, the Thunderbolt as noted previously, as well as a lot of Evos (past the first two LCD brands we had - Epson and the original, name escapes me, it's the one in my Evo) and there hasn't seemed to have been a pentile S-LCD yet.

Info on the S-LCD brand - S-LCD - Wikipedia, the free encyclopedia

All LCDs after the old calculator-types than people have seen have been TFT-LCDs - techs for it include over a half-dozen variants. CP/VA, PVA, MVA, IPS, AVS etc, etc. Outdated, but reasonable descriptions here - TFT LCD - Wikipedia, the free encyclopedia

Please note that discussions of the word "Super" associated with S-LCD came from news blogs like Android Central (oh, what an accurate source).

Super TFT-LCD is better known as IPS.

The S-LCD company produces PVA and S-PVA type panels, not IPS so far as I know. IPS tech would have to be licensed from Samsung competitors.

S-LCD is a brand.

The S stands for S.

There was an announcement last year - by some news blog - that HTC was buying S-LCD panels from Sony. That started the Sony confusion.

When the word Super is applied to an LCD technology, it means something.

There is no technology called Super LCD. None. And Super TFT-LCD is IPS, and S-LCD makes PVA (and possibly CP/VA) variants.

Well you learn something new every day. Sorry for any confusion I called, but I was belieavably operating under the assumption that S-LCD was the name of the screen in the likes of the Desire/T-Bolt/HD7s etc.
