THis is my Quadrant after Lagfix, 2276
[Vibrant Android Development] lando123:
Just wanted to say, despite the speed increase, this did nothing but make my phone extremely unreliable.

I ran this for about 3 weeks straight. Throughout the time, I would routinely have my ringtone changed to something random, appointments on my calendar erased, apps erased or disappear, numerous force closes. Biggest pet peeve was erasing my calendar. I have a ton of appointments made for work which are very important. Having to go back through a book and re input them was pretty ridiculous.

I downgraded back to a nandroid backup I performed right before applying the lag fix, and low and behold, all my appointments were back, which I was glad for. The phone may be a tad bit slower, but I'm not having the unreliability and data erasing nonsense of the 'fix'.

The coder does good work, but this needs a lot more bug finding performed.

Hi.

I'm quite familiar with *nix, so I was using lagfix (not this) for few months.

But, after upgrading to JPC I found my phone be so fast, and decided do not apply any lag fix.

But quadrant... 1180 score is not was enougth $)

So, I decided to use with lagfix app. Again >2000 quadrant score, but NO feel of "speeding up!" anymore. Apps are installing at the same speed or even slower. But uninstall with lagfix is MUCH faster.

So, I stick with fix for few days.

But soon I realized what phone is sometimes quite slow for 10-12 secs. Usually after long "locked" period.

Said "grrrrr" and started monitoring :). Quite fast I found (via adb shell + top) - [kswapd0] system thread consumes 100% cpu sometimes. With NO IO wait!!

Got OSMonitor for monitoring this not only via adb. And [kswapd0] was the only hungry always then my phone really gone slow.

So, fast search on the web didnt get me any idea. I thought "ohh, maybe some app cause it". I removed ALL my apps -- and still [kswapd0] was hungry. At the last step I tried to remove lag fix. And - oh my - [kswapd0] dissapeared. I didnt see that system thread anymore for 4 days as of now. I did reinstalled all my apps with titanium backup -- and still my phone always smooth.

Not sure what really causes [kswapd0] to grab all cpu. Loop device? No, it should not. Maybe this is 1gb file on top of rfs -- I'll try (or somebody else may too :)) to put fake 1gb file (without looping to ext2) and see if [kswapd0] will be again visible.

As of now, personally I do not recommend install ANY lagfix on Galaxy S with JPC firmware. Quadrant score? Oh dear..

This "lag fix" works, but freezes my phone every time I connect it to the computer to charge or transfer data. It never happened before until this fix. Gonna wait for the next update and try again. Had to do nandroid restore since when it freezes the phone, the computer/script doesn't recognize it.

fren, i want to ask smething. After i used ryanza lag fix, my phine have a problem when i want to connect to samsung kies with windows 7 32 bit. My USB debugging also dissapear , i don't know why? can anyone help? thank alot. :)
[Vibrant Android Development] momashi:
Are you using ext2 or ext4 caching?

Hi djkdawg,

thanks for the post and the thorough guide. I saw in your xda signature that you are running a kernel with ext4 support. Are you currently running the ext4 kernel or OCLF ext2? I don't think you can run them at the same time if I understand correctly, right? With which one did you get that insane quadrant score with?

Fadi

UPDATE: I read RyanZA's : Reality behind RFS Lag

http://xdaforums.com/showthread.php?t=799931

which clarified things for me quite a bit. Voodoo turns the entire system RFS partition into EXT4 while OCLF puts a loopback ext2 cache file on the system partition be it EXT4 or RFS. What you seem to have is Voodoo and OCLF running at the same time. Is that correct? It's been a few months since you put up those initial quadrant results, is your phone still as fast now? Have you tried any new ROMs with this combination? Are you still on Eclair?

SGS wont start

Hi,

Can you guys please help me...

I just rooted my phone using Z4root 1.3.0 apk and installed Oneclick lag fix by ryan ZA.

What i did was, I rooted my phone using temporary root and installed the lag fix.

Once the lagfix done installing, it reboots my samsung galaxy s and it stays on the galaxy S screen without and not starting the phone.

What should I do??

Is there anyway to fix this?? pls pls plsssss

[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Noam23:
If you're running Android on your HD2, then battery will last about half of what it lasted with WM. If you take a Desire device, its battery life will be at least double than a HD2 running Android (proving that it's not a fault with Android itself).

When the question is raised of why Android kills the HD2 battery so fast, the usual answer is: "Android for HD2 is still in its infancy stages".

The question is, do anyone has any clue why in this "infancy stages", battery performance is so poor ?, I mean, if you want to solve a problem, you first need to understand what causes the problem, and I don't think anyone understands why battery life is so poor, so why should we assume there will be any progress in this regard in future builds ?

I do believe that developers will probably be able to activate every feature of the HD2, simply because we understand why some features don't work now (for example: maybe we don't have an appropriate driver). Battery performance, on the other hand, seems to be a much more mystical feature, nobody understand exactly why the performance is poor, or what is needed to be done to improve it...

[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Noam23:
What ???, that's the only (or even main) reason ???, the power requirments of the SD card are so much greater than that of the internal storage ?

Many people are reporting poor battery performance even in standby. Is the SD card active in standby too ?

[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Noam23:
Thanks for the tip, but you are not answering my question. In WM, data is not off when the screen is off, yet battery performance is good. With the Desire device, data too is not off when the screen is off, and battery performance is good too.
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Fedr0:
Actually Mystik610 already told you the problem. Yes, running Android from the SD card is the problem with battery performance.

Is the system running in standby? Obviously that it is, so the SD card is active also in standby. Equation solved. ;)
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] amilo123:
Form what I understand it's because cpu scaling isn't fully functional yet... That's why the bottom of the device gets so hot when in use with android. That, along with the SD card and data (witch isn't 100% optimized yet) is why.

these settings worked for me in improving battery life

with setcpu set correctly (+the 925mV kernel) and those power management registry tweaks I'm able to do 2 and a half days with my phone, including usage like a few calls, a bit of browsing every day, about 4h of music and downloading mails four times a day.

Thats pretty impressive for me, don't remember getting much more or even more in WinMo.

[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Noam23:
Something here doesn't make sense. If the main (and surely if only) reason for poor battery performance is because the system works from the SD Card, then why people offer SetCPU as a solution ?, if SetCPU can solve even part of the problem, it means that Android CPU scaling abilities are not working correctly with the HD2 builds. Am I wrong ?

Do people with the Desire device also get the same boost in battery performance after using SetCPU, as the people with the HD2 device ?

SD cards vary in class and power consumption. Get and try a class 2 card and you will see the difference. The latest cards are power hungry even in standby. I asked this question of Sandisk and I was told that the info is only available to devs!!!

It causes the problem with Winnow usage as well especially when you install any apps to the higher class of card.

Using a class two I get a day with heavy usage. Right now after 8 hours I have 60% left.

[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Beefheart:
My battery life isn't poor, it's around what I got under WM. In standby I also get a loss of around 1% loss an hour, that is as good if not better than WM. The key is not to have unnecessary connections running in the background, so that is wifi, mobile internet or Google sync disabled unless you specifically need them.
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] rorydaredkign:
I think you need to be a bit less demanding OP. The battery is poor because they are porting to a device that has no android driver base. So they are writing drivers themselves or porting from very similar devices. This means they wont be 100% optimised so battery usage will be larger. From what I gather power management drivers are the ones least worked on. So battery consumption is high. Thus is why setcpu which scales the speed improves battery. And also why the undervolted kernel improves it too. And of course the SD uses more battery.

Next time rather than moaning, be thankful you have android at all.

CPU scaling (basic PM)

Brightness scaling (basic PM)

Running from SD

Battery Life

I will give you MY reason. May not be yours.

I flashed Mira's rom because of the robot voice and used all builds of android. I set them all up the same way, same widgets, wallpapers, setcpu, sd registry mods, etc.

My problem......The rom!

Some people report good life out of Mira's rom, but after I flashed to Elegancia rom I literally doubled my battery life. Makes no sense to me since Elegancia rom is based off of Mira's rom, but it made all the differnce.

My opinion, which is only because of personal experience, is that there are some roms that lay under android and run processes. I know I read somewhere that everything shuts down when booted into haret, but is that 100%?

Anyone using a barebones having any better life? Haven't tried one yet but a rom change helped me.

Even in this thread, there is disagreement: many people say it's just because of running from SD card, yet other people say the problem might be much more complex [lack of appropriate CPU scaling/lack of Auto brightness/drivers for working features which are not optimized for battery performance/identity of Winmo ROM], while others say that for them android has no problem with battery drainage whatsoever.
