[Nexus One Q&A, Help & Troubleshooting] kerodean:
I don't use GPS much, but when I first got it, I did and it was fine. After about 9 months though its started getting pretty warm, within minutes of using 3g, roughly 38degrees celcius (about 100 fahrenheit), but apparently it's been tested and works fine up to 57 celcius (134 fahrenheit) or something like that.
[Nexus One Q&A, Help & Troubleshooting] mkrmec:
it's not the gps .. it's the turn by turn navi.. it uses massive amounts of CPU that is what heats up
[Nexus One Q&A, Help & Troubleshooting] liam.lah:
It is a number of factors, including the previously stated turn by turn navi. You also have the screen on permanently, plus at least where i live, anything in a car not in an air conditioning stream is going to heat up a lot.

I suggest getting a setcpu widget or some other temperature monitoring widget. I also set my cpu to underclock when it gets above 48 degrees C.
[Nexus One Q&A, Help & Troubleshooting] khaytsus:
Heavy CPU usage, GPS probably generates some amount of heat, but mainly it also adds to the battery draw which adds heat. Screen is on, and you're possibly also downloading quite a lot of data unless your maps are entirely offline.

Also, your phone might be sitting in the sunlight, or in the winter might have the vents blowing over it.

So just the GPS? Not really. Run GPSTest sitting on your desk. You'll see significant battery usage (probably adds 120mAh to what it'd normally use) but it won't get hot.
[Nexus One Q&A, Help & Troubleshooting] syl0n:
Yeah, turn by turn navigation does seem to heat it up a lot, even when caching the map offline entirely on a Wifi network beforehand. My phone isn't rooted, but maybe I'll root it and use setCPU thanks.
[Nexus One Q&A, Help & Troubleshooting] xculliber:
Will actually heat up more if plugged in. Although mine never gets past 115 or so and this is with GPS and music playing.

[Nook Color General] Droidish:
I am sorry if this was already found.

I know alot of people were complaining about the wifi shutting down when the screen timeout occurred. I found a setting in Spare Parts that changes the wifi sleep policy. My NC battery died and is charging so I didn't get a chance to see how well it worked but hopefully it helps.

I set mine to never. I also found that a some of the lg apps posted elsewhere here install and work on the nook.

I for one cannot wait for the roms. This thing kicks serious ass in it's infancy... imagine if someone like cyanogen came on board.
[Nook Color General] norkoastal:
Agreed.. Once Bluetooth is active and hopefully CM6 comes to play this puppy should perform quite well (mouse on screen ya!).. I'm amazed that the 3D games (mainly Gameloft) play so well right off the bat..
[Nook Color General] johnopsec:
I did the same thing in Spare Parts and can verify that the Wifi stays active. I know because K9 on my NC beeps at me a second before my phone chimes when I get an email, even when it's been locked with the screen off for hours.
[Nook Color General] peiziyu:
How does this affect battery life though? I imagine if Wifi is always connected and getting email, it should be a serious drain on the battery...
[Nook Color General] BigBadger:
wifi on = battery drain

Yes it would so use judiciously.
[Nook Color General] golfprorm:
I set mine to never turn off wifi automatically, and then I just use a wifi widget (either the power control widget that's already there) or Beautiful Widgets wifi toggle to turn it off when I'm not using it (during the day at work for example).
[Nook Color General] jdposhkus:
I have mine set to never...Still cuts wifi when the screen sleeps.

Any other tricks to try? I need wifi to remain active....
[Nook Color General] vapor63:
I've tried Wifi Lock as well as Spare Parts, and have the same result. Wifi still sleeps.
[Nook Color General] GuestUSUT:
Spare Parts did not work for me either. I've yet to try Wifi Lock.
[Nook Color General] Dusko75:
Wifi Lock works for me...

Ok.. I read all the posts I could find and installed Wifi Lock, this is the only one I tested and works great for me. (Tested using Pandora radio)

This is what I did:

1- Install Wifi Lock (Android Market)

2- Reboot Nook Color

3- Go to your Extras and run the app. (It doesn't have a user interface, it only displays a message every time you click on it: Default / Never)

4- If you are using Advanced Task Killer (or any other) make sure you deselect Wifi Lock and add it to your Ignore List (I did it right away, I guess that's a VERY important step)

I just tested it several times for about an hour using Pandora radio, I have no idea how much it will drain the battery... If something goes wrong I'll let you know...
[Nook Color General] daithioflionn:
Is this policy of keeping wifi on based on nooks that do not constantly reboot themselves, which is an issue many of us are having. there is a huge thread clarifying a partial fix for the rebooting based on killing wifi when the screen is off.
[Nook Color General] rjoudrey:
I am having pretty good results with "WiFi Manager" in the marketplace.
[Nook Color General] slugbug2010:
never mind - my bad, info was not correct, so sorry
[Nook Color General] notinterested:
This is absolute nonsense.

Wifi never sleep is a massive drain on the nook battery. Its better on a phone because when the wifi shuts off the phones data turns on and uses more battery. The nook has no data connection so when wifi is off it uses next to no battery life.
[Nook Color General] slugbug2010:
Thank you. My bad, I apologize for the bad information.
[Nook Color General] CocoaGoddess:
My problem was a bit different than everyone else's, because when my wifi shut off during sleep, I would have to manually reset my router in order to get the NC to recognize it. Needless to say, this was a huge pain, because we have a lot of devices in our home depending on the wireless router, including our cable boxes.

So, I've been using WiFi Lock on the NC for the past two days. So far, it's only lost the wifi signal once, and I was able to turn it back on within the Nookcolor. Hopefully this will last, because I will gladly take that over having to reboot our rooter.
[Nook Color General] lurker_hlb3:
I would like to pass along some info on an app that I “highly” recommend for controlling the Nook Color’s WiFi. For the last few days I’ve been using “Green Power FREE battery saver”

The beauty of this app is that you can control the “automatic” ON/OFF of WiFi based on when the screen turns off. With it setup to turn off the WiFi with a 0 second time delay I have eliminated all random reboots when the system goes into sleep mode. Also as soon as the screen comes back on it automatically turns the Wifi back on, and my Nook reconnects in about ten seconds. I have tested this in both Infrastructure and ADHOC modes (tethered to my phone) with no problems what so ever.
[Nook Color General] 10equals2:
I thought that CM was going straight the CM7 for the nook?
[Nook Color General] TJNooker:
Update

I have tried Wake Lock, Spare Parts, and WIFILock. I saw the most success with WIFILock but it has been failing lately. I'm going to try Soft Locker next and see what happens.
[Nook Color General] richardop:
The Nook wifi problem sounds very much like the issue the ZTE blade has, I've made an app that creates a wakelock whenever you turn the screen off (if wifi is enabled).

Let me know if it works!

Has anyone spent a good amount of time with both a rooted Nook Color and the Galaxy Tab who can write some impressions on how they compare in regular use? The $350 difference is dictating that I go Nook Color, but it's always fun to hear comparisons before buying...
[Nook Color General] noodles12:
From the "should I get a nook color " thread.

By Bertojg. I couldn't link to the thread from my phone
[Nook Color General] wvcachi:
I was wondering more in comparison to the Samsung Galaxy Tab, but that's cool too.
[Nook Color General] noodles12:
Oh scrap. I can't read.
[Nook Color General] starlabs:
Two of my coworkers got a Tab. It is definitely better than the Nook Color - it's running Android 2.2 out of the box, the screen is as excellent as the Nook's, and it's got 3G, gps, bluetooth, and a camera (if those things are important to you).

It's also snappier as it has a slightly faster chip. It is thicker than the Nook Color though.

The biggest difference is that you can pretty much buy 2 Nook Colors for 1 Tab. :p

If you want the full Android 2.2 experience and the $300+ price difference is not a factor, then yeah get a Tab. :D
[Nook Color General] madsquabbles:
i only tested a display and i was blown away by the experience. all the goodness of the nook (great screen,sturdy hardware, 512MB of ram) with the performance of the archos 70 (much snappier than the nook-but not as fast as the galaxy).

i'm very much considering returning both the nook and archos 70 and just getting the galaxy tab. i only need one (other) tablet anyways.
[Nook Color General] king conan:
The point is, how is the potential of the NC with a custom ROM?

With a fine software many think that the NC will perform almost as good as the Tab...

Time will tell.
[Nook Color General] jerrygon:
I think it will.... Roms do make a HUGE difference with these type of devices. Let's hope someone get one out soon.
[Nook Color General] discourse:
I wasn't too impressed with the Galaxy Tab when compared to the Nook Color. I don't need 3G, bluetooth or a camera because my phone has all of that. I've played with the Galaxy Tab in a store here in Finland and it's quite thick as well.

The Nook Color is thinner and than my iPad but with the same resolution screen and more dots per inch.

The cost is another issue. The Galaxy Tab is over 800euro over here yet the Nook Color came to under 300 euro including 23% local import tax and shipping service cost. I would have bought the Galaxy Tab if the price wasn't so ridiculous.
[Nook Color General] devis:
800 euro... that's 1050 USD. Here you pick up the Galaxy at the store for 600 USD, some 450 Euro.

Gotta love the CHEAP US of A!
[Nook Color General] gojeda:
I think we need to be a bit honest with ourselves here. Let us cut to the chase, the Galaxy Tab is a better device than the NC. It is more capable out of the box because of the hardware it carries, and as good as the Nook Color is, lack of hardware features can never be made up by the best ROM in the world.

This does not mean the Nook Color is a bad device. It is a great device, in its price range.

To me, the Nook is not a competitor to the Galaxy Tab. The Tab is a BMW. The Nook Color is a sturdy Ford, both good - but two different devices that do not compete with each other.

A buyer interested in a Galaxy Tab will not consider a Nook Color (as a Android tablet) just like a Nook Color buyer will not consider a Galaxy Tab. The price differential is just too big.

There is much to like about both devices, but comparing them, IMO, is apples to oranges - and a mismatch from the get-go.
[Nook Color General] excarnate:
Keep in mind who makes the Tab

Like so many others I heard about the Samsung Behold 2 and how those customers got screwed but got a Samsung Vibrant anyway. And like so many others I found out the GPS is borked. And the battery life is poor. At least I didn't experience the lag problem, but I returned it.

And watched for the not-really-promised GPS fix. Which finally came and...didn't work. I really liked the screen and wanted to like the phone, but if the phone can't do what was advertised up front, forget it.

And Samsung on Android 2.3 on their S9000 series of phones (e.g. Vibrant)? Their statement sounded like "Maybe someday if we feel like it and there is a strong tailwind we might think about it but no promises". Maybe the phone is a dead end, maybe it isn't, but based on Samsung's performance so far, I wouldn't count on it. It doesn't have 2.2 yet. My phone (MT4G) came with it, my wife's (DX) got an OTA.

To me this says the Samsung Tab is absolutely out. You'd have to practically give me one to get me to take it. Same for the Nexus S.

The Nook, right now, is not fully tabletized, but that's a matter of software. It has a fabulous screen and seems reasonable in many ways. It is far cheaper than any of its competition (as a tablet). I find it stylish and I could actually imagine reading books on it (I know, what am I thinking?). And my wife is irate that I'm considering it so soon after she got me an Air.

So, is there a Plex controller that is worthwhile for Android tablets? That'd go a LONG way toward getting approval from the missus.
[Nook Color General] xwint3rxmut3x:
I agree. Samsung has never supported their devices well, and they still insist on using proprietary cables and connectors on everything. On top of that, they went ahead and did everything I dislike about apple by releasing the galaxy tab at that price. They are not even trying to compete with the Ipad, they are just assuming that everyone who wants an android tablet will shell out the big bucks to buy it, the same way apple fans will shell out the big bucks to buy anything made by apple. I'm sure it's a good device, it's gotten great reviews - I just don't like the way they went about it.
[Nook Color General] Sirchuk:
My wife told me after I got the NC that she was going to get me a Tab for Christmas. I'm glad I got the NC, I would have had to return the Tab! Too many features in the Tab that I just won't use. The only thing it has that I wish the NC had, is the slightly faster processor (800MHz vs 1GHz.)

Besides the hardware differences, it's a Samsung. They aren't known for providing updates in a timely manner and support on their devices. Sure, we don't know about the NC's status in that respect, but I also don't really care given it's price point. Whatever the development community does is fine by me!

But as was already said, you aren't comparing apples to oranges, you're comparing apples to a fruit basket. It's got more, it's different, and it's more money. I'm fine with apples.
[Nook Color General] wvcachi:
While we're talking about Samsung's business tactics that leave a sour taste in your mouth, two things come to mind:

- apparently they turned down Google's proposal for them to name the eventual Nexus S the Nexus 2 because "we're not #2 in anything." Wow. Surely someone is making a year-end list of "biggest douchebag quotes of the year" right about now - please note this one.

- I'd sacrifice my first-born if the reason for the delay until "after the holidays" for the wifi-only Tab was because of production delays. Either the carriers threw money at them to delay it, or it's just more profitable for them to sell 3g models, so they delayed it (or both). The irony is, I'd more strongly consider a Tab if a $450 wifi model was available now.
[Nook Color General] webvan:
It would be closer if the Nook Color had Bluetooth, that way you could use a Bluetooth GPS, headsets, etc...

...but someone posted in another topic that Bluetooth might be there just "hidden", maybe in a custom ROM ?
[Nook Color General] Babis_ECE:
Hi discourse, I see you live in Finland (Europe), and as I am thinking of getting a Nook Color myself, could you tell me from which online store did you buy yours?

Thank you..!

About the Galaxy Tab, I've played with it for about an hour. My opinion is that it is laggy and definitely doesn't worth the ~600 euros that is its price here in Greece.
[Nook Color General] Sirchuk:
The processor chipset (?) is supposed to include bluetooth. It's assumed it wasn't activated due to licensing costs for bluetooth, so it's there, just not used and may be "unlocked" by a rom.
[Nook Color General] gigadigit:
I've both. NC cannot compare to the Galaxy Tab in user experience.

You just get a much better polished experience with the tab on everything. Tab's gpu is almost 10x faster in polygon count. CPU is faster (even with SetCPU set at performance on NC). Everything just works on the Tab.

That said, I am considering returning my Tab because of all the new tablets coming out in a few months, and the price. NC could hold me over for a few months.
[Nook Color General] xwint3rxmut3x:
Do you know if the hardware GPU is better than the NC or is just based on current software of Tab vs NC? I've done a lot of research into the nook color, but I admit, graphics wise it's still a bit of a mystery to me.
[Nook Color General] Ben74:
i played with the tab in stores, and while it is nice, i wasn't impressed with the speed of web browsing. scrolling large web pages wasn't as smooth as i'd expect given the 1ghz cpu and froyo. since i wanted a tablet mainly for reading and web surfing, this was a major issue for me.

i ended up getting the nook color, and once rooted and with the dolphin browser, the web browsing experience is just as smooth as the tab.

i don't care about playing games, or bluetooth, 3G, etc, so i think the NC is perfect for what i need it for. i think once someone hacks froyo onto it, it will be all the better.

Nook Color GPU: POWERVR SGX530

Galaxy Tab GPU: POWERVR SGX 540

Here is a GPU comparison for some of the leading smartphones:

* Motorola Droid: TI OMAP3430 with PowerVR SGX530 = 7-14 million(?) triangles/sec

* Nexus One: Qualcomm QSD8x50 with Adreno 200 = 22 million triangles/sec

* iPhone 3G S: 600 MHz Cortex-A8 with PowerVR SGX535 = 28 7 million triangles/sec

* Samsung Galaxy S: S5PC110 with PowerVR SGX540 = 90 million triangles/sec

Check out the HTML5 developer scorecard:

http://www.sencha.com/blog/2010/12/09/samsung-galaxy-android-tablet-the-html5-developer-scorecard/

Galaxy Tab beats iPad 4.2 in all the performance testing.
[Nook Color General] xwint3rxmut3x:
OOF, I was kind of hoping that software and drivers would improve the graphics quality a bit. Oh well. It's still not terrible.
[Nook Color General] madsquabbles:
the nook is nowwhere close to the tab. even my archos 70 has a smoother And faster web browsing experience.
[Nook Color General] Hypntick:
Considering I bought the NC specifically to read PDF files, the price point was exactly where I needed it to be. Would a camera and GPS be nice? Sure. But they aren't work the extra $300+ to me. I've actually gotten way more out of this device then I ever expected or needed to. Then again i'm probably one of the only people here who doesn't have a cell phone of some type. :D
[Nook Color General] stwallman:
Yeah, but that's really because both the Tab and the A70 both have Froyo on them. I would expect that once Froyo hits the NC, it will have significantly better performance as well. I know when my original Droid 1 went from 2.1 to 2.2 the speed was significantly faster.
[Nook Color General] Ben74:
I should have mentioned that you can't evaluate the NC based on the stock browser. It's terrible - different and somehow worse than the standard Android browser. Dolphin greatly improves the browsing experience on the NC. Yes, you have to root it but if you're an xda reader, you probably will anyway.
[Nook Color General] testulous:
Some quick notes about the NC compared to my Galaxy S i9000m and my bro's iPad:

1. the default browser on NC is awful. No multitouch + superslow. I'm about to install Skyfire on it to compare with the Galaxy S (nearly same hardware as Tab). Apparently the speed issues go away with better software?

2. NC's screen is gorgeous. NC has an antiglare Super-IPS screen with a wide viewing angle. That angle is for real, this screen is as good as a non-AMOLED can get.

Compared to the iPad, I think the screen is better because it reflects less ambient light and is just as responsive and has a higher DPI.

3. Videos play smoothly, but NC won't play MKV files (at all) or MP4 videos with Bframes. I think it's a software limitation, will install a video player to test this theory. I have a pretty nice Handbrake profile that works flawlessly so no it's not an issue. Samsung Galaxy S plays pretty much everything I've thrown at it. Haven't tested the iPad with video and I don't even care to anymore.

4. Tab + iPad = proprietary cable. NC = MicroUSB (same as Galaxy S).

Ultimately I chose the NC over an iPad because the iPad is a chunky hunk of heavy, slippery tablet. NC > Tab because of the ridiculous price and because NC is svelte. It feels amazing in the hands, very solid and sleek but not slippery. :)
[Nook Color General] discourse:
Hi Babis_ECE

You need to jump through a few hoops to get one :)

I singed up with shipping service and got myself a US shipping address for free. Then I signed up on B&N with that address using my European credit card. I bought the NC, they shipped it to my shipping service address then the shipping service charges you around 35euro to ship to Europe + whatever import taxes your country has. Mine came to 280euro.

I used Borderlinx shipping service. There are others that may be cheaper but I have no experience using them and this one came highly recommended.

You could also just try ebay.
[Nook Color General] gigadigit:
SetCPU NC to performance and Dolphin HD browser help with the speed and smoothness.
[Nook Color General] Babis_ECE:
Thank you for your answer, I will check Borderlinx out..

The only thing that holds me from ordering it now is the import taxes I'll have to pay, and here in Greece they are quite expensive.. :(
[Nook Color General] madsquabbles:
Only on the tab have I used the stock browser. I prefer xscope and dolphin. Ocing the processor does improve the browsing, but it's still not as fast as thearchos. The archos is faster in both eclair and froyo. Even neocore runs better even though they havethe same gpu - though th nc has 224 more pixels to render.

I'm not saying I'm not happy with the nc, for 250 you get the best tablet around at the price. I'll most likely be returning the a70 because of the stability issues I've been having. Its speedy, but buggy as hell. I'm sure once we get custom roms this bad boy will put the tab to shame price/performancewise.... not that it doesn't give you the bestbang for the buck already.
[Nook Color General] xwint3rxmut3x:
That's also interesting, doesn't the a70 have half the amount of RAM?
[Nook Color General] cal3thousand:
And a resistive touchscreen?
[Nook Color General] madsquabbles:
it's capacitive and does have only 256MB. it has terrible memory management too. you absolutlly must yes a task killer. even my droid wasn't this bad with memory.
[Nook Color General] madsquabbles:
instead you can just lower the threshold so it samples more times per second and decrease the up threshold while keeping it "on demand." this will give you faster cpu scaling and maintain a lower clock when not needed.

some one did a test a while back and found higher sampling didn't affect his battery much.

just found the article: http://www.droidforums.net/forum/rescue-squad-guides/47871-overclocking-101-a.html

it's been a while since i've read through the whole post but it's pretty informative.

i have mine set at 150000/65/0/0

i set the up threshold to 70 and 75 but with too much stuttering still. 65 seems to work fine. i have no way to test this difference by anything other than "feel" though.
