To celebrate the N1's V2 thread, I ..... unleashed my kuda kepang.

But, I only did very minimal modifications..

1) Use my own compiled kernel 2.6.32.9 android.git kernel + Under Voltage patch
2) Update radio image...

Next.... change dalvikvm....

that's it ...not need to change everything...

Will update later... now, monitoring my kuda kepang running around the cage/farm.. .

Updates, just done the dalvikvm JIT.

http://forum.xda-developers.com/showthread...=652911&page=24

FYI, my N1 stil in STOCK ROMs ERE27 built, with minimal changes.

I did the Linpack benchmark... without JIT... around 7MFLOPs,.. with JIT ............ see for yourself...
BUT, with a CATCH... 3 standards apps will FC ...
1) Google Voice
2) Google My Upload
3) MP3 Store...

I hope that are the only apps which failed with the JIT mod...

TQ.

Revert back to stock dalvikvm. JIT enabled dalvikvm is good but stable for reliable usage.

24 hours on my compiled kernel. Very satisfied.

I don't any fancy screenshots, but hope this screenshot will make the N1's user's haapy

Location : On my bed, in my house in Balakong
Time : 2010-04-19 : 0453 am
Telco/service : Celcom 3G, voice+ unlimited data plan

Note: This is the best download speed ever. BTW, everything depends on the telco's network condition... so it might varies all the time.

You must ROOT before you can app2sd.

Look at "Battery Usage'. Which processes were the battery sucker?

Or, try to use other KERNELs... example DIET kernel...,

You will get this message...



The same message I got on the first day of the N1's launch, 3 months ago

ROM? ... Just stock 2.1update1, ERE27 build. Eventhough I rooted my N1, but, still using the stoock ROMs.

Errrr... BTW,, I think all the N1 users will charge their N1 when they are going to sleep ...

N1 is not like 'Nokia 3210', an old basic phone anymore.. If I am not using it, standby mode, I then it can last 2 or more... But, for normal use, I also got almost about 24 hours.

I think shahz has some tips to maximize battery life... BTW, what is the most battery sucker app ?

It has been the same since day 1 , where I cannot proceed because of the shipping address was not in the 4 test countries.

TQ

Based on my N1 experiences, the most power hungry 'part' is the DISPLAY. I estimated, I can get 300 hours of standby if I don't use the display/screen at all:).

Also, I am limited max CPU frequency to 500MHz all the time and use 'conservative' cpufreq's governor. Still I able to play 3D games withou any problems. (+ using slimmed down kernel) . For the example, I got 26.8 fps for 3D Neocores benchmark, but only 3.6 MFLOPS in Linpack's benchmark (7MFLOPS@998MHz) . Since I am just uisng the N1 typical smartphone, without any number crunching calculation, I safely can set the max cpufreq to 500MHz, or less if I wanted to


I watched the How to save battery life clip, and if you realized, the battery usage for Display was 7% @ 13h47m9s at the starting of the clip. But, if you look carefully at the end of the clip, the Display used 8%@13h54m17s ... so in about 7 minute, Display consumed 1% of battery life .

So, by less using the display, we can save quite significant amount of battery life. I set the screen timeout to 15sec, or set to standby just after using it. Previously, I used the Task Killer, but, now I just leave to Android to handle it by itself. I just need to monitor Battery Usage more frequently .

Other things are, I am using any LIVE wallpaper. If you are using wallpaper, use a wallpaper with 'darker' tone. Because, OLED will use more power when it want to produce WHITE or whiter/bright colours. In my case, I only use solid black wallpaper.

2) I am using any widets, except the Google Buzz widget.

3) Always check battery usage or running apps if you feel 'warm' Sometime, your N1 might working hard to get connected to your telco, so, make sure you have a good reception. Luckily I am living and working at places which have strong signal

4) Use less Google Maps. ... Why?
a) Google Maps must use 3G connection... this one is quite power comsuming
b) Your screen need to be on all the time... further more, the Map is in WHITE which consome even more power.
c) GPS chipset and CPU must do lots of calculations, more power to be consumed .

Thank you.

How long my N1's battery can last with very minimal usaga , few phone calls, replaying gtalks, check status......

I got .... 35hours... with 29% left. Should be able
Now we can see that tha Screen/OLED display is the real power sucker... Snapdragon chips are quite qood and impressive when running Android.s

No comment about the camera quality.... but for sure, the Carl T Zeiss branded lenses has it's own specialty. BTW< HTC is not a camera/lenses comapany, so I don't really care much.

BTW,

So, start marketing...

My father inlaw's Nikon compact digital camera with 3.2 MPixel is MUCH MUCH MUCH better than N1's

Actually snapdragon is very efficient chipsets. Furthermore android os and linux kernel are very efficient software too. Even at 500 MHz, most of the apps are running smoothly. Why need more?

Anyone who has AP with wireless N:
Please try the Nexus One's Froyo wlan-N capabilities. It should connect at N mode.


I also found the QuickOffice PDF viewer is much usable now, with the multitouch zooming.

Thanks for the clarification.

To unlock bootloader, ypu need the fastboot util
