abou the battery issue, you can try to recalibrate your battery stats,
i'm using froyo too and from the 1st time i'm using it, i don't have a problem at all, and in my experience, i think the battery is better than eclair.
to recalibrate the batter,
1. you can empty the battery until the phone is off
2. charge the phone in off condition and leave it for a night
3. turn on the phone while still plug
4. go to root explorer, go to data-system, find and delete batterystats.bin
5. unplug the charger.

The battery issue in this Froyo ROM isn't related to calibration, but with CPU scaling. For some unknown reason the scaling governor of this ROM is set to "Performance", which means the CPU will run at full speed (600 mhz) all the time. I found a way to work arround this by installing SetCPU and setting the "on demand" profile applying at boot. Instead of SetCPU you can also add the following line to the end of my install-recovery.sh script:
Code: 
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

This will make your CPU behave better, allowing the kernel to use lower frequencies when not so much power is needed.

Almost. The problem is you'll loose this setting everytime you restart your phone and will need to re-apply. My script makes the change at boot time, so you don't have to worry anymore :)

About the display driver: I don't know if SG5 is capable of multi-touching. I didn't try to do anything about that and probably won't since I just sold my SG5 in order to buy a new Nexus S :)

It saves only the apk files from what I see. ;)

This is a very good method, but the update to Froyo for the I5500L asks you when you install an app, weather you want it installed on the phone memory or on the SD card. Plus it fixes the phone coma bug. ;) I'll try it on my phone once I open it ;)

Is it safe to try these method on another phone instead instead of Samsung Galaxy S?

If it doesn't work, can it brick my phone or something? Or it simply won't work?

I tried it on my zio, seemed to work alright until I rebooted, then none of the apPS were found. I was having trouble with adb at the time though and did all the commands through the terminal on myphone. I probably just made a mistake somewhere. haven't had the chance to try again since

hi, first of all: cool thread.
i'm gonna try it as soon as i'll get the sdk and emulator working on my ubuntusystem (i'm a long time linux user, but not a developer.

about the tutorial here are some advice, expecially for linux user.

maybe you wont need to install busybox (correct me if i'm wrong).
i have an european i5500, with installed "universal androot" and "quicksshd" (an ssh server, it gives you a console, like adb). so i access my android from my ubuntu machine with ssh, and even if the cp command is not present, scp command IS present (dont know if builtin or came with ssh daemon ).
so for the step 10 of the tutorial you can scp to your pc and than copy back to the phone. (and you'll also have a backup of your .apk on your pc... you can never know)

about the script, i suggest:
if you want to keep a copy of some apps on the internal flash, in order to have them working also with other sd card, i'd skip the step 14 of the tutorial (at least for some apps), create a file in your sd root (or wherever you want) ex. pippo then add between line 5 and 6 of the init-sd2.sh something like:

if ( ! cat /sdcard/pippo ); then exit; fi
and optional
if ( ! cat /sdcard/pippo ); then echo wrong sdcard; fi

in this way when you reboot with another sd your phone should save and use the apps on flash memory as usual.

i may have made some mistakes, so please check before try.

Can it be done on Windows?

Errr... all these procedures seem so Unix-ish... Can all this be done on windows, especially windows 7? If there are different steps can some one give me a pointer? thanks!

    DISCLAIMER: DO THIS AT YOUR OWN RISK. I AM NOT RESPONSIBLE IF YOU BRICK / RUIN YOUR PHONE IN ANY WAY.

    Hi Everyone,

    I have some good news for the owners of Samsung Galaxy 5 (i5500) Smartphones.
    Doing some research on Google and reading about efforts from other people who could install applications on SD card on other android phones, I was able to develop a method to install application into SD card for the Galaxy 5. Better yet, you won't even need a custom Rom.

    Before I get into the specifcs let me state that the following steps are manual and no application is provided to automate the process, so advanced computer skill is required and some knowledge of unix/linux is a plus.

    Here we go: PLEASE READ THE WHOLE THING BEFORE YOU START. I MAY HAVE OMMITED SOME COMMANDS OUT OF LACK OF ATTENTION.
    1) You'll need to root your phone. There is a lot of guides about this available, just google for it. I've used the SuperOneClick Root to do this.

    2) Partition your sd card like this: 1 - FAT, 2 - Linux ext2. Again, there is a lot of guides about this on the net, just google again. I've used Paragon Partition Manager 2010 to lower the size of my FAT partition, leaving a 550MB unallocated space at the end of the card. Then I formatted this space as ext2 in linux, using ubuntu live CD. Most guides around there recommends that you keep this partition between 500~750MB, so I didn’t try with greater sizes. Also, i kept my partition 1 as FAT 16, but FAT 32 might actually work too, try that if you want and post me a reply.

    3) Download Titanium Backup (or another app backup tool) from market and backup your applications. You may need to restore your applications to correct some permission problems that may occur after completing this guide.

    4) Install busybox. BusyBox is a software application that provides many standard Unix tools, which are not available on stock android. You can get a copy of busybox by clicking on “problems?” button on Titanium Backup main window. It will get installed on /data/data/com.keramidas.TitaniumBackup/files.

    5) If you still don’t have Android SDK installed on your PC, download and install it from Google. You’ll need ADB (Android Debug Bridge), which is included in the SDK, to proceed. Now open a shell connection with your device by typing:

    Code: 
    adb shell

    Just keep in mind that you MUST be logged as root. Root command prompt is recognized by the # character. If you don’t have root type the ‘su’ command. If even with ‘su’ you couldn’t get root, please review step 1.

    6) Create ‘sd’ folder int /system:

    Code: 
    cd /system
mkdir sd

    7) Mount ext2 partition into /system/sd

    Code: 
    mount -t ext2 /dev/block/mmcblk0p2 /system/sd

    8) Create a folder to store the applications into ext2 partition:

    Code: 
    cd /system/sd
mkdir app

    9) Copy busybox to /system/bin
    Code: 
    cat /data/data/com.keramidas.TitaniumBackup/files/busybox > /system/bin/busybox
chmod 755 /system/bin/busybox

    10) Copy your applications to ext2 partition:

    Code: 
    busybox cp /data/app/* /system/sd/app/

    11) Change permissions of copied applications:

    Code: 
    cd /system/sd/app
chown system.system *
chmod 644 *

    12) Now comes the tricky part: making Android mount your new partition at boot time. All the hard work would be useless if Android discarded the mount points every time we restarted our phones. To do this we’ll need to create 2 scripts and store then into /system/etc. Obviously the scripts should be started by init.rc and need to run as root. Fortunately Android’s init.rc have a gap that makes this possible. The scripts are named install-recovery.sh and init-sd2.sh.

    install-recovery.sh content:
    Code: 
    #!/system/bin/sh
/system/etc/init-sd2.sh&

    init-sd2.sh content:
    Code: 
    #!/system/bin/sh
MYLOG=/data/install-recovery.log
echo "$(date) Starting install-recovery.sh" > $MYLOG
echo "$(date) Waiting SD to become ready..." >> $MYLOG
sleep 10
mount -t ext2 /dev/block/mmcblk0p2 /system/sd 1>>$MYLOG 2>>$MYLOG
mount -o bind /system/sd/app /data/app 1>>$MYLOG 2>>$MYLOG
mount >> $MYLOG
echo "$(date) Finishing install-recovery.sh" >> $MYLOG

    If you plan to edit this files on windows I recommend a tool that is capable of keeping UNIX file format, just like notepad++ free tool.

    13) After placing the scripts, change their permissions:
    Code: 
    cd /system/etc
chmod 555 install-recovery.sh
chmod 555 init-sd2.sh

    14) Rename the default application folder. If everything works fine you can remove this later to save space:

    Code: 
    cd /data
mv app app_old
mkdir app
chown system.system app
chmod 755 app

    15) Restart your phone and cross your fingers :)

    16) If you have problems with your widgets don’t worry. You just need to remove then from your homescreen and add again.

    17) Check if your applications are running as they should. Restore backups you’ve made with Titanium Backup for the applications showing problems.

    18) If your partition didn’t mount at boot, check log file at /data/install-recovery.log

    19) From now on your new applications will be installed on your SD Card. You can modify the scripts to store other folders from /data into the ext2 partition as needed. I’ve been running my applications from SD Card for a week now without any problems or bugs.

    20) If you can’t make it work, post your question here and I will try to help you out.

    21) Donations are welcomed, just drop some money into my paypal account. Just kidding :p

    Good luck and cya!

    Hmmm. Try this instead (logged as root):
    Code: 
    cd /data
mkdir app_old
cd app
mv * ../app_old
