Where are you checking the temp? About Phone >> Battery Use >> No temp?
[Nexus One Android Development] Prod1702:
check under Spare Parts, Battery info
[Nexus One Android Development] metalhead8816:
No hiccups on the new version for me.

Charging from the AC charger at 18.5C

Thanks so much for the great work!!!
[Nexus One Android Development] swetland:
Yup. The voltages in the table as shipped are based on extensive testing by Qualcomm and HTC -- including burn-in / stability tests running for days across a number of devices across wide temperature ranges.

I'm honestly surprised to hear that anyone is seeing significant battery life savings by underpowering the CPU. The power savings you can get by shifting the cpu regulator should be mostly noise compared to subsystems like the radio, display, gps, etc, and the CPU is actually completely powered down much of the time (even when the display is on).

/d/battery_log is your friend for looking at the most accurate power consumption numbers possible from on the phone -- the gauge IC in the battery.
[Nexus One Android Development] Gimpeh:
23.7 C. I guess its working if the temp is so low at idle.
[Nexus One Android Development] r0adki111:
I was getting these errors too. I went back to #2 and errors are gone. I will stay here for a while. Well.. until you release a different one ! haha
[Nexus One Android Development] persiansown:
Thank you for that info man. We're just trying to learn :) I know radio/display draws the majority of power, but what do you mean when you say the CPU is actually completely powered down? Do you mean it is at 245 or that it is actually off?

And the tested voltages are based on the lowest common denominator correct? As in some devices will be able to go lower but not all as we are seeing here.
[Nexus One Android Development] swetland:
Whenever the system is going to be idle for more than ~50ms (no kernel timer expiring within that window), the CPU is completely powered down. When the system is going to be idle for less than 50ms the CPU is put into a "wait for interrupt" state where it does no work (but is powered and clocked).

Yup. Yields vary, so some individual chips will survive (further) out of spec than others. The voltage/frequency combos in the table as shipped are (based on specification and testing) expected to give the best reliability. If you start mucking with them, some devices may work fine, some will fail right away, and others may be okay depending on what temperature the CPU is at, etc.
[Nexus One Android Development] persiansown:
wow, that is the most amazing thing ... ever. Thanks for the info. Do you mind if I add you on Gchat to ask you a few questions? I'll understand if the answer is no though, lol.
[Nexus One Android Development] swetland:
I'm happy to answer random questions (when I have time) here, but I already get a pretty crazy amount of interruptions in the average day, so I avoid IM.
[Nexus One Android Development] persiansown:
Understood. Thank you for your help in both this and in the community in general.

Just want to share my experience. If you get VDD after flashing the second one. Change your device to auto detection in SETCPU:D

Testimonial

According to Android OS Monitor and BatteryIndicator Pro my phone temp is currently at 15.0 C, this is with the first kernel posted. Im afraid to flash the second. Just to give an update on the battery saves: I unplugged my phone from the charger at work at 12am and left it on my desk, when I left work at 1:30am EST i noticed the battery was still at 100%, normally it would be at 98%. I decided to do a benchmark while driving home. I plugged my phone in my car's system through the rca cords that come with the nexus dock, loaded up pandora and used google maps to navigate home (gps on). When i got home at 2:05 am (30 miles later) my phone was down to 94% and the temp went up to 21.0 C. I am just amazed at this mod you have done, I am wondering if this could also be done on the G1-Dream. My wife has one and her battery always dies within 8 hours of use. By the way while writing this I am at 90%. Thanx again. Cyanogen should use this mod in his ROMS moving forward. Someone get him in here....
[Nexus One Android Development] r0adki111:
Are you still getting vdd errors?
[Nexus One Android Development] persiansown:
I wasn't using setcpu at all and I got the problem.
[Nexus One Android Development] flak0:
thanks for your discovery and effort. this is great..
[Nexus One Android Development] flak0:
Persian and Swetland I do have a question. Now that most of the northern hemisphere is in winter this is awesome for the phone ; however would it pose any danger if when summeer comes around temps are topping 90+ degrees F and the phone is below that temp, could it cause any form of condensation which could fry the chip. I know it may sound stupid but its a what if. Thanks again..
[Nexus One Android Development] ericchik:
VDD appears again. My method should be useless.:(

Sorry everyone:(
[Nexus One Android Development] Gimpeh:
I still have yet to get anything here. Although I havent been using it intensely.
[Nexus One Android Development] persiansown:
I found the cause of the issue with VDD.. It doesn't like dropping below 1.0v. I made a new kernel that I'm going to test until tomorrow. If I don't get any more errors, I'll release it.

Any reason for this Swetland? Or am I just doing it wrong?
[Nexus One Android Development] swetland:
The values in the table, as shipped, are known good and reliable. If you change them things can and will fail (though exactly where and under what conditions will vary from individual chip to chip). I don't believe the CPU can operate at all below 1.0v.

If you want the most reliable operation of your device, you are best off leaving the voltage scaling unmodified.

Thanks for the instructions. But I think I'm mad.

I've Problems at step 3.

I've copied the instruction and paste into cmd /androidsdk/tools (the right folder)

My Nexus is in System (Driver ADB is okay)

My error is: waiting for device.

I don't now how, but it doesn't flash it.

The two things in zip are in the tools folder, it's typed correct, my nexus has "USB Debugging enabled", it's rooted and works with Cyanogen 5.0.2.

What do I wrong?

Sorry, I'm with stupid.

I've tried that not in bootloader......

[Nexus One Android Development] Nighthound:
Hi guys,

I'm curious about the battery life that you all are getting. I'm currently having problems getting my phone to last more than 9 hours on a full charge, with moderate to heavy usage. Checking emails, surfing net, IM through Meebo, a bit of GPS, etc. But nothing significantly draining like continuously video or downloads.

As of this writing, my phone has been unplugged for 3h 10min, and I'm already down to 63% battery. According to Settings > Battery use, the main usage comes from:

Android System - 37%

Cell standby - 28%

Phone idle - 21%

Display - 9%

Camera Zoom FX - 4% (I was taking some photos earlier)

Does this seem typical usage behavior?

Also, not sure if this matters. I stay in Singapore where the temperate ranges from 28 - 33 deg C. My battery temp is currently 33 deg C while sitting at the home screen with the screen on. I guess it is reasonable that the device should be about or warmer than the surrounding ambient temperate. When under heavy usage, it can even exceed 40 deg C.

Wondering if undervoltage in my case would help to increase the battery life.

Hi,

My phone cant ADB,Fastboot works fine though..

kept tellin me adb server is out of date.killing...

*daemon started successfully *

list of devices attached

(empty)

Fastboot works fine,been playin for 2hrs plus..read though alot thread,still dun know y..

So all the more i need to push the .ko file to the right spot..can kindly advise y i can only copy/paste/move file within my sd card..the option is grey when i try to copy the .ko file to the directory of my phone system..

thanx in advance..
[Nexus One Android Development] Nemphys:
Battery life

I am sorry my friend, but Meebo is DEFINATELY your problem (unfortunately). I was also astonished seeing my batter go down really quickly when I was running Meebo. If you check "partial wake usage" in Spare Parts, you will see that your phone is actually not sleeping at all while meebo is connected. I have already dumped meebo and using tha native gtalk client instead, and through some weird jabber (and MSN) transports, I can be online to my corporate jabber account, gmail and msn from the gtalk client...

As for this new kernel, I was excited to hear about it and flashed (1st version) last night. Today, having unplugged the phone since 11 AM, I am now (4:51 pm) at 57%, with alsmost NO usage. I am almost certain that this is much worse than normal. I don't know if it makes a difference, but I am running CM5.0 b4 (with the ERE36B radio and ERE36B Google apps).

Any ideas are welcome...
[Nexus One Android Development] FormelLMS:
Try downloading the AndroidSDK for new.
[Nexus One Android Development] Nemphys:
CM5.0 b4 kernel needed

Btw, does anyone have the CM5.0 b4 (highmem) kernel in a flashable zImage format? I want to flash back to it!
[Nexus One Android Development] Ogglord:
Might help to reinstall the drivers

Download "USBDeview" and remove all HTC/google drivers that represent your phone. Plug in and pick sdk/usb drivers when asked for drivers, then ADB interface should be displayed in device manager/properties of the phone
[Nexus One Android Development] asci:
@persiansown

Do you advice me to wait for your fixed release?
[Nexus One Android Development] persiansown:
I've been running it since last night and haven't gotten any VDD errors. As Swetland said, I don't think the processor can run below 1.0v. As to whether or not you want to wait, thats up to you. Expect a release tonight if none of my testers have any issues with it.
[Nexus One Android Development] 2khong2:
Thanx for the advises..tried both methods..

Now readin bro th3fallen thread..

mayb molo try the adb on my lappy win7..

Thanx again for the head up..
[Nexus One Android Development] FormelLMS:
I think you can reinstall your cyanogen rom without wiping.

Then you have your cyanogen kernel back. Isn't it so?
[Nexus One Android Development] rheza02:
yes, just do this "fastboot flash boot boot.img"

boot.img from your rom.
[Nexus One Android Development] FormelLMS:
OK, overflashing the cyanogen rom doesn't work? Do you mean?

It's so:

The ROM is on my SD Card, I can flash it everywhere. At Home, at office, at beach... ;-) and it tooks 5 Minutes.

P.S.: For now there is no reason to get back from this kernel. ;)

4 hrs, 5 Percent, moderate using. (Twitter/SMS/Email, 1 call, short Navigation through city!)

Persian it might be a good idea to add release dates or numbers to the title. ive installed the first version i believe and didnt notice a new one until i looked at the thread again. im not getting any errors on the 1st release and it seem rock stable so far. 10 hours standby whilst i was aslp with setcpu on i lost 5% battery apposed to the 20% prior. goodwork
[Nexus One Android Development] persiansown:
I had it changed at first, but there were issues with the new one and it has been temporarily pulled. Once I release the updated version of it, I will repost it.
[Nexus One Android Development] pzumk:
what about an oc'ed undervolted kernel? possible?

Yes. Thats the next step :)
[Nexus One Android Development] FettsVett:
If wishes were fishes we'd all cast nets in the sea. :)

experiment yourself with it, maybe your hardware can do it. I think Persiantown is going for stability on the widest range of devices possible, your idea would decrease that range :)

Erm, I'm running Modaco 1.6 and my battery temp is 12.8oC?!?! (unplugged and not flashed with this undervolt)

Do you think he already has some kind of undervoltage in his ROM?

Either the sensor is wrong, or you live in a refrigerator. thats 55.8 degrees Fahrenheit.
[Nexus One Android Development] AndyCr15:
Sorry, Fahrenheit means nothing to me...

It's gone all the way up to 16 now. It does feel very cool though, so I don't think the sensor is wrong. My room is kinda cool, I would guess somewhere around 10oC?

[Nexus One General] dnanj:
First off I apologize if this thread may turn out to be inappropriate for this section of the forum.

I know this isn't really Nexus One specific, but it is Android Development related.

I'm having a somewhat slow day today and was doing some reading about the N900 when I happed across an interesting blog about a dev who managed to get his N900 to dual boot Maemo and Android.

http://blog.broberts.com/nokia-n900-with-maemo-and-android-yes-please

Apparently, it appears to be at the stage where it's just a proof of concept, but I have to admit that this is awesome to say the least. Anyway, I just thought I'd mention it here, where cyanogen, modaco and the rest of xda's talented dev's might happen to read it, in hopes that it might spark additional developer interest.
[Nexus One General] W3ber:
why nexus one and others phone need multiboot?

like as winmo+android android+maemo

next thread :( say maemo ported to android:)
[Nexus One General] dnanj:
I'm not sure if you misread my post. But this isn't about getting the Nexus one to dual Maemo and android, but to get android running on the N900. Not that Maemo isn't a great OS, I mean the N900 is a basically a fully operational computer/tablet, but the choice of apps on it is still limited. Regardless, the fact that it has flash and the fact that you can run practically anything from the browser does make up for it to some degree. Still, the N900 isn't really a consumer friendly device that others assumed it was going therefore getting android ported to the N900 hardware would be really sweet.
[Nexus One General] jairuncaloth:
I don't think full on Maemo is open sourced but the parts that are I believe are released under a project called Mer. Since we've figured out how to boot debian. I don't think it would be much of a stretch to boot Mer.
[Nexus One General] stewart1988:
Is it Maemo or MeeGo? Or are they both completely different projects? :confused:

So dual-boot is possible? I must of missed this stuff.. Would be cool to boot to a different OS

First off, I want to say thanks to Kam187 & the Creators of asroot

Okay, Below is the Method I used for getting Root working for my app's.

Even though Shell is running as Root, any Call's made to su trigger's the white List Superuser.apk, So don't think your phone is wide open. G1's & MT3G Setup's are the same regard sh.

I'm not sure is the apk is counted as warez or not, if so I hope a Mod will remove the link to the Apk or let me know to Remove it...

Okay, File's Need to complete the Task is....

Try3 Placed in C:\SDK\tools> found here > File's attached below

SU for /system/bin found here > File's attached below

Superuser app control for our App's found Here > File's attached below

Next, Mount the SDCARD and place the SU file in the root of the sdcard like so ( /sdcard ). This is Important!!!

From here we do the Following.. ( Kam187 script the I edited ).

Once Done, place the Superuser.apk in your SDK tools Directory.

Mine happens to look like this

Once you have that Copied over, Open a Command prompt and CD to your sdk\tools directory and type the following.

Once done, do a reboot of the Phone, Once boot up is complete open a Command Prompt ( or app that needs Root ).

For Command Prompt, type:

If done correctly you will now see the deny or allow prompt on the Phone, or just open any app that needs root & you will see the same window.

Here's some Picture of it working

[Hero, G2 Touch Android Development] alexellis:
Which Android SDK version is required for the T-Mobile G2 Touch?

I see under about phone several numbers:

firmware: 1.5.

build: 2.73

software: 1.0.0.A6288

Could someone tell me which the actual Android SDK version I will require is?
[Hero, G2 Touch Android Development] nprussell:
Just treat it as a Hero. Forget the T-Mobile nonsense.

Mine is technically a G2 Touch.
[Hero, G2 Touch Android Development] foxmeister:
You only *require* the SDK if you wish to develop applications for the phone.

Nowadays, you download the SDK starter package, and then add "platforms" for the various versions of Android that you may wish to target. Currently available platforms are 1.5, 1.6 and 2.1.

Unless you are running a custom ROM, your Hero will be running Android 1.5, so you need the Android 1.5 platform.

Regards,

Dave

[Touch Diamond2, Pure General] Mike Austin:
I know this has been asked before, but has anyone yet succeeded in connecting an HTC TD2 or T-Mobile Compact V as a Bluetooth modem to a PC running Windows XP? I can ActiveSync via Bluetooth, but that's all.
[Touch Diamond2, Pure General] hungtinglung:
Need extra command string in bluetooh modem setting.

AT+CGDCONT=1,"IP","APN"

APN is your ISP access point name.
[Touch Diamond2, Pure General] Mike Austin:
I don't follow. Surely the PC needs to see that there is a modem first? Has your PC recognised the bluetooth modem service on the phone?
[Touch Diamond2, Pure General] pa49:
If your phone is already setup for data access then you don't need any dialing string.

When the PC establishes the BT link it should install the dialup service which will access the phone as a BT modem!
[Touch Diamond2, Pure General] Mike Austin:
"Should" is the operative word. Dialup service as such is not used on WM devices. They use a Personal Area Network (PAN). Anyway, the point is that no services on the phone can be seen by the PC. If I can overcome this hurdle, the rest is plain sailing (or plain surfing?)
[Touch Diamond2, Pure General] pa49:
I use Blue Soleil BT software and the services are installed by it and not Win. May be that's the difference. Do you have any BT client software running?
[Touch Diamond2, Pure General] Mike Austin:
The problem is basically what the WM device is communicating - or not communicating. I have an IBM/Lenovo laptop running XP/SP3 and I cannot find services on the WM device whether I use the Microsoft BT stack or the Lenovo BT stack. I have also tried a separate USB BT dongle with its own drivers without any success. A colleague with Windows 7 (Microsoft BT stack) cannot find services on the WM device either.

Do you see all the services on your phone with the Soleil BT software? I have an old BT dongle that uses BT Soleil.

I think BT on WM devices is a bit shaky. My in-car Parrot hands-free sometimes recognises it as one device and sometimes as another - but surprisingly it works regardless.
[Touch Diamond2, Pure General] lapimate:
Yes, using Internet Connection Sharing [ICS] via Blue Soleil on WXP Prof.

One has to start ICS from the 'phone - it should ask whether to use USB or BT, then (unless your mobile 'phone supplier has forced a fixed choice via a registry entry "ForcedCellConnection") allow you to specify the connection to use (eg Internet) then it will advise to go to PC and click on BT PAN.

I've been playing around with the files responsible for the lock screen to mimic this functionality.

With there being no documentation it's quite difficult. I just restarted the whole thing, my last attempt had a few issues.

The main problem is, I can't figure out how to have a vertical slider. Horizontal is fine, but not vertical.
[Windows Mobile Development and Hacking General] Irishpride:
Definitely keep me updated on your progress, I like the new look a lot more than the standard WM6.5 lockscreen. It would be great to have use of this on our phones.
[Windows Mobile Development and Hacking General] itsme_4ucz:
me to buddy damn qute.
[Windows Mobile Development and Hacking General] RJackson:
My current progress isn't any good.

Decompiled lockscreen.dll, it seems the 'slider' is hard-coded to be horizontal; meaning I can't achieve the same result through editing the CPR file.

The only thing I can think of is writing a whole new lock screen; something of which I have little idea on where to start.

No doubt I'll continue looking, seeing if there's any other secrets hidden in system DLLs that I could use; as well as seeing what I'd have to do to write a new lock screen.
[Windows Mobile Development and Hacking General] Irishpride:
I kind of figured it wouldn't be easy, which is too bad cause it looks so much better. Thanks for looking into this and if you do figure anything out or start work on one, let me know and I will happy to help test it.
[Windows Mobile Development and Hacking General] player911:
Yea I was looking at that build which lacks the start menu and ok button. I really like that. My 2 hardware buttons never get used because they are on the screen... might as well rid them of the screen and get used to the hardware buttons.

Also the lockscreen looks like a stock lockscreen just modified.

HTC moves the lockscreen files into \Windows\Lockscreen. If I had a rom dump I could probably get something working.

Just enable the pattern locking in the security settings. Android does not permit a numeric passcode, but instead relies on a drawn pattern. However, it limits access to the entire system. You cannot limit access to specific apps.
