Powertop

Tried searching but didn't see anything already posted....
Cyanogen posted on twitter:
powertop for android binary: http://bit.ly/VfOUN .. it needs a kernel with timer debugging enabled (this is in the CM kernels)
Its a tar file that you download. I tried deploying the files but I get an error:
Error opening terminal: unknown
Here is how I deployed the files......
Code:
# pwd
pwd
/system/etc/terminfo
# ls -l l
ls -l l
-rw-r--r-- 1 0 0 1672 Jul 3 00:47 linux
# ls -l u
ls -l u
lrwxrwxrwx 1 0 0 10 Jul 3 00:49 unknown -> ../l/linux
# ls -l /system/bin/powertop
ls -l /system/bin/powertop
-rwxrwxrwx 1 0 0 286648 Jul 3 00:42 /system/bin/powertop
#

I get the same problem.
My guess is cyan is going to include it with 3.6.1 so we can just wait for that to be released.

ive tried various things too. cyanogen, must use some voodoo to get it to work. chmod 777 the 3 files changing PATH, TERM and terminfo, no avail

From cyan on twitter:
if you can't get powertop to work, try "export TERMINFO=/system/etc/terminfo" first
Tried it, still no luck though.

Screen shot of the problem

GOT IT!
Code:
# su
su
# export TERMINFO=/etc/terminfo
export TERMINFO=/etc/terminfo
# export TERM=linux
export TERM=linux
# powertop

Attached some screenshots...
It suggested "increase the VM dirty writeback time to 15 seconds"...
I think that was part of the sysctl.conf tweak thread. I haven't redone those tweaks since I wiped and put cyan's new ROM on my phone. Interesting.
I wish my dos prompt would work with ANSI control codes so I could run it through ADB...

BTW, the tweaks it suggests are for X86, not Android. Most can be ignored, especially the ones about kernel options.
I included it with 3.6.1 too.

So what exactly does this do?

How did you find this website if you've never used a search engine before?

I didn't find anything specific to android.
Just like a "check what consumes most power"-app.

Does accepting powertop suggestions reduce the speed of the phone?
It is currently suggesting
Increase the VM dirty writeback time from 5.000 to 15 seconds with
echo 1500 > /proc/sys/vm/...
Another one it suggest is
Enable the CONFIG_NO_HZ
Enable CONFIG_USB_SUSPEND
Enable CONFIG_HPET_TIMER
in kernel conf option

A few questions:
I've been running my phone with Open Overclocker at min 528 Mhz / max 528 Mhz. Would it save battery life to put the minimum lower? (I've found that the lowest you can go is "001 / 528" (leading zeros are necessary).)
How do you implement the VM dirty writeback? lmfwtw says "echo 1500 > /proc/sys/vm/...". But what is the "..."?
What is gp_timer? It always seems to be the #1 cause of wakeups by FAR. Next is futest_wait, and sometimes m2m_i2c. Can they be shutdown/decreased?
Is there anything else we can write to the kernel to save power? I found this, http://ubuntuforums.org/showthread.php?t=729644 but I have no idea if any of that is applicable / will brick my phone.

Yeah thats what I found too.
Dont pay any attention to that dude, he likes to play pretend moderator at times and ***** at people for useless posts when in fact his posts are just as useless and adding to the garbage that clutter up threads.
I found this: "Powertop is a Linux command line tool that monitors your laptop (or desktop) and offers suggestions on how to make your hardware consume less power."

I have some other questions as well, but I'll wait. Does anyone know the ones in my last post?

Found in another thread...
Do NOT use 128/528. It hurts battery life and the processor. The jump between 528 and the idle frequency is big enough to require extra circuits to be switched on. That does two things... slows down the gain of the processor speed and hurts battery life more than simply running permanently on 528.

I assume going 001 / 528 would be even worse. Hope that helped.

Thanks. Actually, last night after I put it on 001/528, I started having freezes almost immediately. For example, each time the screen rotated when I took the keyboard out, it froze. And when enabling an Alarm, the toast message caused a freeze. And they were 100% full freezes, ie had to take the battery out. After about 5 full freezes, I decided to go back to 528/528 and everything went back to normal. I guess I'll stay on 528/528 hah

[HOWTO] Getting Hero To Run Fast

A lot of people have a tough time with Hero/Sense ROMs. I thought I'd make a guide on what I do to help others out. This is not definitive but it's my personal way of doing things. Comments, tips and suggestions are welcome here. I will update this with some more info as I go along.
I have a MT3G but this is the same for G1.
**Firerat has really comprehensive guides for A2SD and other tweaks. Please check his thread for more info. Also, his post about setcpu profiles is a must read.
First, get a ROM. I'm currently playing with KingKlick's Legend Port and Vegaman's kernel update.zip. This guide applies to any Hero ROM though.
Table of Contents / Overview
First things first
Get your task killers in order (TasKiller, AutoKiller, etc.)
MyBackup Pro or similar if you use them
Autostarts-- one of my favorites. Would love to hear about a free alternative
Droidwall-- free, blocks Internet to apps you choose
Reboot, wipe Dalvik-cache, reboot
Additional steps, Misc, Errata
FIRST:
Partition your SD card. I set a 256MB swap partition and have copious memory left over even under heavy load. EXT2 is better than 3/4.
Flash the ROM, flash the kernel update after. Boot the ROM, go through set up. I always skip signing in at this point as the setup is heavy on the CPU and wait for things to settle before the memory intensive sign in process begins.
SECOND:
Okay, now I see the home screen. Install TasKiller (free/paid) with ADB, MyBackup Pro and kill all the processes except Sense. I highly recommend Autostarts (paid). It handles not only autostart processes but also event listeners and will significantly speed up the ROM. Here are the services I disable:
"After Startup"
Download Manager
My Uploads
Network Location
PC Synchronization
HTC Message Uploader
Peep
HTC Media Uploader
Flickr/FaceBook/MySpace/etc
com.htc.socialnetwork.provider
HTC Widget Download Manager
MyBackup Pro (Uploads your location to their servers at every boot!!)
"Connectivity Changed"
My Uploads
Network Location Service
HTC Message Uploader
HTC Media Uploader
com.htc.socialnetwork.provider
"Application Installed"
PC Synchronization
Pico TTS (why would text-to-speech need to run...)
If you use Slacker.. disable it completely from all "Application Changed/Installed/Removed" categories. No need in them knowing your usage..
"Screen Off"
TasKiller
Notice how (and you can watch with logcat) when an application is modified or installed, it starts up Pico TTS (text-to-speech), synchronization, etc. This is not necessary and a memory hog. You might also be thinking "but I needz muh Facebook" but you don't need it to autostart. These services will load on demand as you use them. Without them, things go a lot quicker.
THIRD: (If you use MyBackup Pro)
Now, I sign into my account with Market, accept the terms and conditions. Once things have settled and I'm able to use the Market I exit the app immediately. I use MyBackup Pro to restore my apps. Version 3 now links apps to Market so they can be updated. Pretty slick despite the fact it logs your location to their servers without your permission. Luckily Autostarts stopped that. Now there's a small catch-- MyBackup messes up the Market database. Easy fix with ADB:
Code:
# cd /data/data/com.android.vending/databases
# ls -l
[I]I summarized the output here for formatting's sake..[/I]
----rwxr-x assets.db
-rw-rw---- billing.db
-rw-rw---- webview.db
-rw-rw---- webviewCache.db
See how assets.db is owned by root and the wrong permissions? This will FC Market 10/10 times. So:
Code:
# cp assets.db BACKUPassets.db
# cp -p billing.db assets.db
# cat BACKUPassets.db | tee assets.db
# rm BACKUPassets.db
Now it will work. The theory is that we can't chown the DB due to an "unknown user" but the other files there have the correct permissions. We use cat and tee to overwrite the clone with the correct contents. It's a hack that works perfectly.
FOURTH:
I then reboot and go to the Market. Install Droidwall (free) and set it to blacklist any app that doesn't need Internet Access. I also install AdFree (free). One site that it doesn't block is flurry.com. This site is used by a lot of applications such as MoreLocale. It uploads personally identifying information about you including your location, phone number, account info, etc. without your permission. I append it to my hosts file afterward. Note that each update with AdFree will erase that entry but I use Autostarts to disable it at boot and never update.
Code:
# mount -o remount,rw /dev/block/mtdblock3 /system
# echo "127.0.0.1 flurry.com" | tee -a /system/etc/hosts
# mount -o remount,ro /dev/block/mtdblock3 /system
FIFTH:
With all the apps now installed that I want to start out with, I go back to Autostarts and disable those I don't want (pretty much all of them). I reboot into recovery mode and wipe Dalvik cache. Reboot, wait for it to cache again and all is well.
Additional Steps
You can easily lock home into memory. *thanks speedysilwady and firerat. Here's how to set this permanently:
Code:
adb pull /init.rc
[I]replace "setprop ro.HOME_APP_MEM ..." with:
[B]setprop ro.HOME_APP_MEM 1536[/B]
[/I]adb push init.rc /sdcard/init.rc
adb shell
# mount -o remount,ro rootfs /
# cat /sdcard/init.rc | tee /init.rc
# mount -o remount,rw rootfs /
# rm /sdcard/init.rc
I will update this as I go. Any comments and tricks like reducing call delays are welcome. Again, this is just how I do things. Hope it helps.

Reserved for the updates....

Reserved for more updates. Just in case.

Don't bother getting kings version just get Vegaman's 0.3 version.
It works a treat and fast as well...
EDIT= and on Vegaman's use EXT2 not EXT4 like you have to do in kings roms. EXT2 is faster then EXT4

Awesome thread! you could also use AutoKiller and Cachemate to keep things smooth as well! =]

Updated OP. I'm looking for the prioritizer script that supposedly gets incoming calls within 1-2 rings... will update when I get it figured out. I have between 40-55MB free memory according to TasKiller when no apps are running.

I agree...and great job thread creater!!!

Interesting! I will try this, how much will the speed increase be?

With what I do, I barely get any slow downs unless I run a lot of apps but I have TasKiller's mini taskbar on one of my home screens and always clear things out before I do something like web browsing, Maps, or games to keep RAM clean.
I'd love an alternative to Autostarts that's free but it is truly great. Blocking listeners causes a huge boost in speed. You will see in logcat when you install an app that all these services start running in the background like Voice Dialer, TTS, etc. That's the reason installing apps seems to peg the phone for a few minutes. Not so when you block those background services.

It's bad to have a large swap and high swappiness.

I haven't had any issues. The swap partition hasn't clogged up or even gone under 100MB left for me yet. Your mileage may vary but it's what I set it to. What size/swappiness would you recommend then? 96MB is not enough, 128MB seemed like too close to the edge of what I need.
I need to make the OP not look like crap...

It is better for the life of your sdcard to have a large swap....because if you allocate say only 64mb to swap...those blocks on your sdcard are constantly being written/read and the rest isn't....better to have a swap of say 256mb so that you are evening out the stress on the blocks more.
I think Wes G or Chris S said this....but that's my paraphrase of it.
Also no difference in speed between a 32mb swap and a 256mb swap. Just depends on your sdcard's class.

If we were talking about computers then swap would be same size as ram, it's better to have no swap at all then to have one

Try Fireat
But for purposes of speed, a large swap partition will get full eventually, and when it does, have fun trying to use your phone. It gets slower because swap has to "dig" through more files to get what you want, the more files it has to dig through, the slower it is. However, you won't notice this if you reboot often (and I guess 5% of Android users reboot daily)

None of newer ones use it for a reason, you would use back-swapping instead(Cc+swap)

Lock an App into Memory

I'm a heavy AIM user, among other things on Android. For me, AIM always closes when I minimize it, so I tried alternative apps, like the application Hi AIM, which I personally like a lot too. The good thing about Hi AIM is that it has a constant icon in the notification bar showing that it is active therefore I know whether or not I'm signed in or not/if the app has been dropped from memory. I ran several tests IMing myself from my computer with the app open, it works fine even if i minimize it and navigate around my phone. However, if I open up the browser and start loading a website, the icon disappears, and all subsequent messages sent are dropped. This is a large problem for me and therefore the only solution I can think of is locking the application into memory. According to Advanced Task Manager [which I do not leave on, I only use it to check memory], with my phone on standby I usually have around 19-28MB of free memory. I have the 10MB ram hack, as well as CompCache and 32MB swap. I am running the latest Super D with Dark Star theme. The browser obviously has a large memory load and is causing the AIM app to be dropped in favor of running the browser quickly, is there anyway I can lock the AIM app into memory? I understand there will be a minor general slowdown of the phone overall as a part of the memory is now purely dedicated to that single app, but AIM is something I use a lot.

Yes.
I'ts pretty much this thread: http://forum.xda-developers.com/showthread.php?t=652147
Their solution is to "download the AutoKiller app" and press "keep alive"
hope this helps

You just made my day. Thank you very much haha

Advanced Task Manager also works for what you require.
Been using it for awhile now and am satisfied enough to not use another app for such purposes.

I don't know what/how to change this, but this is the code you need to make the sense home app stay in memory. Perhaps its similar to the way you make any other app stay in memory?
Code:
adb pull /init.rc
replace "setprop ro.HOME_APP_MEM ..." with:
setprop ro.HOME_APP_MEM 1536
adb push init.rc /sdcard/init.rc
adb shell
# mount -o remount,ro rootfs /
# cat /sdcard/init.rc | tee /init.rc
# mount -o remount,rw rootfs /
# rm /sdcard/init.rc

A2SD view apps loaded in partition

First post, hope I haven't picked the wrong place. I did search the forum before asking this.
Is there a way to see the A2SD partition, or to see the apps installed on it? I set mine rather low, at 512MB (that's what it asked for at default) and I figured that should be more than enough since I only have ~100MB or so on stock ROM.
So yeah, none of the market apps I have seen can show me the space being used or how much room is left free on the partition.
Any idears?

Quick System Info in the Market, will show you the total amount of mb being used and what is left for a2sd.

Connect to your phone via USB cable and enter the following in a command prompt (this of course assumes you have installed the android sdk):
adb remount
adb shell
ls /system/sd/app/
I got this from this post: "forum.xda-developers.com/showthread.php?t=603052"
just put the http tag in front of the above and cut and paste it into the browser address bar.

Thanks, to both of you. The Quick System Info App does the trick!

[HELP] Low internal memory...what?

Alright, so I'm gonna start off by saying this could be something really obvious, maybe too obvious to turn up any results in a search because I've looked, but here's my problemo:
Got a G1 (obviously), running CM5.0.8t4. I've got Apps2SD enabled, 1gb out of a 4gb micro sd card, haven't used up even half of that. But today I suddenly got a "low internal memory" warning and I was thinking huh?? I had only 8mb free out of 88 mb (or around there) So I looked around and someone who posted a similar problem was told to clear the system cache, so I figured "Oh, that makes sense". I downloaded CacheCleaner from the Market ('cuz I'm lazy) and I figured it would free up some crazy massive amount...but no, it cleared up 1 teeny mb...
It's not my apps, and it's not the cache: so my question is...where the HELL did all my internal memory go??
Thanks.

it is the apps "data" being saved on your phone, and not on the sd card. "data" such as, your high scores in games, or settings of an app, log-in info for an app... etc... u have to go into each app that you have installed on your phone (by clicking on them from the applications setting menu) and then hit "clear data" or some **** like that for each app.... that should clear some space up. and make SURE the apps are being installed on the SD card, and NOT on the phone.

It is true hitting clear data will clear up SOME memory, however I don't believe that is the typical way people gain memory back. If you choose to do this REMEMBER THIS. If you clear data for the Messaging App, you will lose your texts. Same with the Contacts app, you will lose your contacts and call log. For the Launcher, you will lose everything on your home screen.

HEY...don't jack my help thread! >__< (but I'll give you the benefit of the doubt and assume it was a mistake)
And as for the guys that replied, thank you very much, I haven't gotten around to trying the method of deleting that app data yet (got another issue, atm), but I'm POSITIVE that that's the memory-hogging culprit

I will second what Lieu10ant said.....clear data/cache of apps (I usually sort by size - browser and market are huge culprits) and also double-check the apps are saved to SD and not to the phone.
Also clearing cache will not delete bookmarks, log-in, SMS, etc, only clearing data will.

You can check Firerat's scripts for CM, this gives a bit of breathing space on G1 low memory, link for that is http://forum.xda-developers.com/showthread.php?t=679572

in terminal type:
Code:
su
busybox df -h
If /cache is full (>90% used)
Code:
cd /cache
rm *.apk
rm -r dalvik-cache
It fills up every time you get things from the market. This command will clear it out.
