Screen background should be set to white.

Turn off 3g, location and manually set brightness.

Battery life lasts about 16-18 hours of moderate use, 10 hours of heavy for me.

I always charge before I go to sleep though.

Radio

I'm seeing a lot of people stating (not in this thread) That any radio BUT the 2.15.xx radio is a massive battery lifetime boost :)

if somebody can really confirm this (i flashed my radio yesterday, so i can't tell yet), you might want to add this to the OP.

Fully charged the buttery under WP7.

Reboot under Android and it said my battery was only at 80%. :confused:

Is there any chance WP7 says that battery is 100% (and it stops loading) when it reaches the level it had when we flashed it?!? :eek:
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] crpntr:
I get at least 12 hrs with heavy use and easy 16 with light . everything on but radio never flashed to 2.15 was 2.10 if I remember .

maybe its due to the mobile operator architecture! :confused:

correction

dark colored themes on wp7 are hell on anything not named amoled...lighter themes do save a lot more battery if you are on an lcd/tft display

and while I can understand everyone saying that the battery could be better, remember this OS is not even supposed to be on the device right now. It doesn't help with the battery issue but at the very least you can understand that support is slim on an OS of this nature on a device like this

What saving more power at hd2 ?

white Theme? or

black Theme?

Thanks
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] jemaho:
I think that one point that has to be said is that the battery meter is far from being accurate. While I work, I got my phone usb plugged. The led was green on the phone meaning the charge was done, I unplugged my phone and at the same moment, the meter was only half empty.

Other example, 2 days before, the meter was almost empty, and I've been still able to use my HD 2 all the morning before getting an alarm.

Black (dark) uses less power. With a light background more power is used to light up the screen pixels......

I downgraded the radio from 2.15 to 2.14. Will see if that helps.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] seanyuan62:
Thanks for the pointer! Can anyone confirm this?
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] maxld:
Yes I can. Changed the radio to 2.14 and after whole day and night my battery barely moved. I have to admit though that I made maybe 3 calls and sent 1 message in that time, still it is very impressive - phone after 19 hours is still running, and has still about 70% of battery.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] jcsy:
my phone is only registering 90% as "FULL"

on WM7, i charged it to full (Yellow indicator)

and when I boot into Android, it shows 90% and cant charge further. at 90%, its at the correct reading of 4.200V

i cant get it up higher :(
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] theguy:
Wrong. On LCD screens (as our hd2) white uses LESS power.

On AMOLED screens (omnia 7) white uses MORE power.

We want white backgrounds on hd2 to maximize battery life.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] jenzy1985:
is this really true, everyone says something different
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] geddeeee:
White uses more power. It doesn't matter which screen you are using.

Black is value 0, which means the RGB values are all off. No pixels are lit.

White is value 255, which means the RGB values are all fully lit.

I have tried both methods, and the black background is definitely more battery efficient.

I'm getting roughly 30 hours with a dark background......
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] theguy:
As I said, wrong.

From http://www.scientificamerican.com/article.cfm?id=fact-or-fiction-black-is clearly explains why white is better for power consumption on LCD's. You need a diffuser to block out the white light on an LCD and the act of this draws more energy on black backgrounds as you have to block a lot of the light.

Here is a google search with more links you can look at:

http://www.google.co.uk/search?q=lc...lcd+black+or+white+&pbx=1&fp=ff7438fb088773d1

Once again, on our HD2's a white background is best for conserving and attaining maximum battery life.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] geddeeee:
The science may be correct, but in my extended tests, the black background was better for battery life. But that was on MY HD2.

Every one will obviously have different results. There is no hard and fast rule...

Whatever works for you.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] theguy:
Fact is, your 'extended tests' aren't going aren't going to be conclusive. And fact is setting a white background will get you ever so slightly better battery life than having a black one, regardless.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] jcsy:
i thought on LCD, everything is lit up regardless of color

constant power draw

for PLASMA (like on TV's), it doesnt light up black since its dark enough
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] mslog:
Everyone is saying different things!! Is black or white the better setting??

[Desire General] dijipo:
Lets make this easy:

-Tried to install CyanogenMod on my rooted Desire using the ROM Mananger.

-Installed it but it got into a loop at the CyanogenMod boot logo

-Searched around and found out that you had to go into recovery and try to reflash there

-Every time I go into ClockworkMod Recovery, there's a message "E:Error in CACHE:recovery/log (No space left on device)"

-Tried to wipe data/factory reset

-Got a black screen

(It seems that all the options give me a black screen and the only way I could solve that is to remove the battery)

I was told to reflash the recovery, but how would I go about doing that?
[Desire General] TheGhost1233:
Pleas don't tell me you also try to confirm actions in recovery with the power button. Use the trackpad/optical joystick instead, the reason the screen turns black is because you actually turn it off(simple press of the power button should fix it and not pulling the battery). Also make sure in recovery you wipe data/factory-reset, cache and dalvik cache(under advanced)

3.Select the PDA in Odin.

4.Turn the phone into the download mode by pressing and holding VolumeDown+Home+Power.

5.Connect your phone with your computer and wait until the drivers are installed.

6.When the drivers are installed, click Start.

7.The phone will be flashed and once it’s finished, it will boot up. (Do NOT disconnect the usb-cable, remove the battery or otherwise interrupt this process!)

8.You have successfully flashed your phone.

[G2 and Desire Z Q&A, Help & Troubleshooting] randomsuffix:
Hey there,

I got my Desire Z a few weeks ago. About a month. When I first got it, there was only a small problem - A few of the keys on one row of the keyboard didn't work. After a reboot though it resolved itself and since then it had been working fine.

Until now, sadly. A few keys on the keyboard, S, F, G, J, K and L don't seem to work. They light up with the backlight, they are still in position and click just like the other keys. The software just doesn't seem to respond.

Any ideas if this could be a software issue, and if there's anyway I can test that out, besides just typing in apps?

Cheers

[Nook Color Themes and Apps] CodeWhite:
Hey All,

I have used these forums as my main resource for android for a while now, and this is my first time having to post a question because everything is usually so well documented.

I bought a nook color a while ago, and have love it. I take college classes at night, and obviously would love to use it during said classes. Getting books, and PDF's for it are easy enough, but i am looking for an app to take notes with. I am not a huge fan of using a touchscreen keyboard to take notes which i have done in the past. Does anyone know of a solid handwriting recognition app that would be useful for class? or any other applications that would be useful for class in general?

Thanks You.
[Nook Color Themes and Apps] Mbside:
I don't think it may work fine for that purpose at least you have a stylus and a handwriting app cause its kinda annoying to take fast notes in this keyboard wether you use portrait or landscape mode because of the size
[Nook Color Themes and Apps] CodeWhite:
There has to be something a little more intuitive to take notes with than having to type everything... right?
[Nook Color Themes and Apps] duloz:
So far, the best I have seen for handwriting recognition on android works like so:

Write a word

Wait

Omfg, it guessed wrong, rewrite word

Rinse, repeat until it gets one word right

Class is over

Do yourself a favor and buy a pen and paper

I mostly use my Nook Color as a supplement to my desktop at home in college. We are a big Google Apps school so we share everything over Google Docs.

My plan (I will start using my NC for classes tomorrow) is to use an app called blackink. You can have different notebooks for class and either draw notes or type notes. You can also sync to evernote and dropbox. At the very least I will be using evernote, dropbox and a scanner to minimize the files I keep from classes. But yes, if a working BT happens note taking in class will be much easier!

Seriously, what happened to taking notes, then transcribing them later, adding details, revising? For me it helps solidify the information in my WET data storage.
[Nook Color Themes and Apps] nookierookie:
I teach first year English, am a grad student, and I use this thing with taking notes, reading pdfs, etc. The best setup I've gotten really fast with is using Evernote (which syncs between my ios devices and my Macbook) with the SlideIT keyboard. Certainly faster than trying to use handwriting recognition or the few times I've played with the ipad on screen keyboard. I usually ignore errors and clean up the notes later when I'm at my macbook. Almost as fast as writing by hand, for me at least.

Nb I also really push for my students to use Evernote. The Mac version is slightly more full featured than the windows one, but both are good and the android and ios versions are great.

I tried a targus stylus made for the ipad and it didn't work out too well at all. I tried it in magic doodle and it can't even draw a straight line or circle consistently.
