----------

Hi guys,

I'd like your help to find out which Wifi firmware versions are included with which PDA firmware package.

This is what you can do to help:

1. Find out your Wifi firmware. Turn on your Wifi, then do:
adb shell "dmesg | grep Firmware"

You should see output with the Firmware version of your Wifi.

2. If your firmware is different from what other people have already found, then if you can, please package it and attach it to your post. You can do this by:

adb shell
su
cd /system/etc/wifi
tar cvzf /sdcard/wifi-(your PDA firmware version)-firmware.tar.gz *
exit
exit
(Back in DOS)
adb pull /sdcard/wifi-(your PDA firmware version)-firmware.tar.gz

Then upload the tar.gz file.

Please use the full 5-letter version of your firmware name, for example XXJPY, and not just JPY, or DXJPA, and not just JPA.

This is what I've found so far:
DXJPA: Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214.3
XXJPY: Firmware version = wl0: Nov 16 2010 08:56:21 version 4.218.250.38

You have to turn off and on your Wifi first. The driver will print the firmware version in dmesg everytime you turn on wifi.

I have the same as yours:
XXJPY: Firmware version = wl0: Nov 16 2010 08:56:21 version 4.218.250.38

I must say that the situation is improving after about 12 hours on JPY.

I have an outlandish suspicion - dO you know if they have started to use Google Backup to store Apps and settings? Maybe it syncs with Google/Samsung when the phone is Idle? And maybe it happens only on Wifi.

well... i meant to do it later tonight - but heck - let me try it for a couple of hours now

PS: flashed and it now says DXJPA: Firmware version = wl0: Jun 4 2010 14:21:21 version 4.218.214.3 - will report how it works in about couple of hours. If its any better than 8% - its good.

How did you measure power usage and is the signal strength affected ??

I don't know yet, thats why I'm asking people to try it. But so far DXJPA has worked well for us in the past, so it should work well now too.

If we can identify the wifi firmware of XXJPY being the cause of higher battery usage, then we have a ready solution - use the older wifi firmware.

1 hr mark - mostly idle - looks very good - 1% drain... which is close to normal (with JPA firmware). And no big %age in "Running" - its 8% - which again sounds normal compared to the 40-50% earlier.

Update:
2 hrs - and the drain is 4% - not the best ever - but looking close to normal. Running is 10%, Wifi usage though is still 25% - but given that its just 2 hrs, that seems ok.
