How to Speed up your Hero - My Way

Well i already tried speeding up my HERO by following the steps from another thread here in the forum and it just didn't work for me.
So Heres what i Tried and it just seems to work out for me! And its very simple too.​
THIS IS VERY IMPORTANT: DOWNLOAD "OVERCLOCKWIDGET" FROM THE MARKET AND SET THE MIN MHZ TO (128000) AND MAX TO (528000) MHZ. THIS SHOULD HELP KEEP THINGS RUNNING SMOOTH.
^^^^Also from the settings of "OverClock Widget" you can set the MHZ Frequencies while the screen if off to the a low but not so low Frequencies in order to save battery!
So if your like me and like to have a lot of widgets on your phone then Using Task manager to kill certain apps might just do the trick....
First of all never end applications such as
com.htc.socialnetwork.provider
com.htc.provder.weather
HTC media uploader
Touch input
HTC Location Service​
and more! They do not have an icon if your using "advance task Manager" All other apps are good to end such as music,peep,market, Messages,Mail, Google Mail, and of course Browser which uses a lot of memory.
Give it a try and let me know how it goes...​
Heres the link to a video i made to show the performance of my HTC Hero!
Not the best quality.

Thats the way i do it to.
But i also noticed, that some widgets uses more battery than others. After i removed quick calender and digital clock, i got better battery performance. That might also have some effects on the processing power

I tried this...
This afternoon and so far this morning the Hero is far more responsive after I wake it up (which was when it was at its most laggy).
I can now immediately slide around the home screens. Before I had to wait a few seconds or suffer ignored screen swipes.
I was not using the Stocks app or widget but it was set to auto update so set it to never update.
Maybe its a process that runs regardless of whether you use the app or widget ??

Know what I think might work? An app that reboots the phone.
User selects frequency of reboot (daily? every 2 days? every week?)
User selects time of reboot (12 midnight? 3 am?)
User defines Countdown period (15 seconds? 30 seconds? 1 minute?)
At the user-defined time, the app will run itself, and prompt the user "Reboot Now?". A countdown timer will start.
User can select 'Later', 'In 10 minutes', or if there is no interaction/input, when countdown reaches 0, the app will reboot the phone automatically.
This way, users will always wake up to a 'fresh' phone. What do you guys think?

Rebooting the device won't make it faster. On the contrary you have to start every apps for the first time so it takes more time.
You'd better leave it on and turn to airplane mode when you don't need it.

Tell that to my phone. It's back to it's zippy self after a reboot, and only slows down after I run Maps, Browser, Google Talk, Market and HTC Mail

I think clock should also be spared of killing, as if I recall correctly, something bad could happen to set alarms (not setting off, volume too low etc.)!

Hi guys, need some help.
i've just rooted my Hero thanks to this article http://forum.xda-developers.com/showthread.php?t=543571 and Quick Boot (which needs root) now works perfectly.
After i've installed overclockwidget i cannot start it as it gives me an error "Star-up error - cannot start Overclockwidget (need Root)".
Any ideas?
thanks in advance.

Surely increasing the CPU speed will also increase battery drain ?
Its also likely to lead to instability and additional heat (Hero gets hot enough when working hard).
Personally I would be wary of doing this.

I have no real issues with battery drainage after tweaking the processor speed; lasts about the same as it would w/out the tweaks.
I do see some minor performance improvements, but on the flip-side, the phone can also get sluggish at times upon waking it up from sleep.

I'm confused, my hero runs at 528 stock o_o

wrong, mine runs at 528 MHz, and I haven't overclocked it

I can confirm that mine shows 526 (the widget number) as well out of the box. And changing the settings doesn't appear to do anything. It's always returning to 480Mhz - 528Mhz when I restart the app / widget. I've tried this both with SetCPU and OverClock Widget.
The Hero (at least some Heroes) seems to be immune to fiddling with the cpu. And I am sure I'm rooted, because I enabled paid apps in Android Market with MarketEnabler and that's working.
MarketEnabler didn't work out of the box tho - because it had a script that relied on Grep and Grep isn't installed, so I had to empty the AndroidMarket cache by hand from the terminal... Maybe there's something similar preventing fiddling with the cpu speeds?

mssmison did it!: CyanogenMod 5.07 test 3. for kaiser!

Heads up! New Kaiser Wifi update: http://forum.xda-developers.com/showpost.php?p=6456191&postcount=33
Old one replaced build.prop with wrong version. Reinstall and use the new Wifi update.
Also to get rid of android-rebooting-problems with GPS Test application do the following:
1. Start terminal emulator
2. su
3. cd system/lib/hw
4. rwsystem
5. rm sensors.msm7k.so
6. rosystem
7. exit
8. exit
9. restart phone

So how is it? I'm too lazy to install it.

Seems like a really nice build. I'm using 320x428 with 144 dpi. A bit slow because I'm currently not running in NAND but I would expect it to perform quite well once I go back to running NAND again.
I haven't tested it very much yet as I'm doing some experiments in WinMO at the moment.

just tried
hey
i just downloaded this and i have to say im impressed about this.
as i love the eclair design and everything and the donut speed i have to say this is impressing because it is FAST! not as fast as donut but pretty much the same. that could be due to the 500 mHz OC but i just like that build.
just needs to be optimized a bit, maybe a few apps like astro and others
and as the developer has a new phone we need a new one.
But i have to say its awesome!
i love it already and just tried it for 9 min.
just the OC needs to be removed i noticed right now and is there any way to set another value for the screen sensebility because quiet often it does not react on a touch.
so keep updating this!
nick

nice rom but it chews through battery like crazy. With a full charge battery will drop from 99 to 75(battery fix removed OC and set 1400 value) with just a 10min phone call and a couple txts. I think what we need is a new kernel highly optimized for battery life using the latest patches. Judging from the name alone of the kernel its running right now 2.6.25-01051-gc362ac-dirty and the fact that 2.6.25 was released in jul 2008 i think theres room for tons for improvement.
Does anyone know how to adjust the microphone gain? my friends complain they cant hear me..

The wifi scan interval is set to 15 seconds by default in this release. That will have a negative effect on battery life if you are out of range of a known network and have wifi enabled. I'll put together an update to change this when time allows. I use 120 seconds myself.

Thanks to update.
It working good on Polaris.
Also i change interval to 180 and density to 120 in .prop

Here's an update that changes the wifi scan delay to 120 seconds and also (not tested yet) changes the model name from Vogue to Kaiser.

i'm still trying to figure out if it's possible, somehow, to flash an update.zip file (to be able to use the cyanogenmod skins) with the nomorootfs we're using, instead of converting the skins to metamorph format
does anyone know if it's possible or how to do it?

Can't get wifi to work with updates, which one should I need?

kallt_kaffe's works for me. If something isn't working like it should, power off the phone and remove the battery. Then hold down the power button to remove any remaining power left. Place batter back in and try again.
Also, make sure to always fix permissions when you apply updates, even for wifi.

edit: how stupid can I be? I've bought another phone and forgot to add the mac adress.

Certainly think mod needs work. So far the battery meter is off, and all this time I thought it drained less power. A lot of pop ups to force close apps. A lot of apps are running that I don't use.
mssmison didn't say he was going to put any more effort into it either. Hopefully, someone will pick it up.

Have you removed or renamed /lib/modules/hw/sensors.msm7k.so? After I removed that it runs very stable for me.

kallt_kaffe how do you do it?
I'm new to the androidinstall.tar method. I'm tyring to run from haret but it seems impossible.
You said you where experimenting with something in winmo, so that implies you're using haret? Are you running from haret?
When I try, Polymod, and Mssmission they don't show an install option, when I try myn and incubus I get it installed but I get no sound. It was actually your gps kernel that let me get things installed all other kernels i tried had non-functional dpads within the installer environment. Also, trying another kernel once installed didn't fix the sound issue.
Anyhow just let me know if you're using Haret. I wonder whats up with the sound and missing install option. I tried the install two different ways one with a 2gb fat32 partition, and then another attempt using three primary partitions 1.3gb fat32, 300mb ext, 300mb ext. All installers then would give me options beside's fat, but not all intallers would have an install option.. I'm using radio 1.71.09.01.eMo, model: kais100, os: wm6.5 (shifu v.3)

battery life has been fantastic for me on this build...
although I reverted back to 400mhz and got rid of compcache.
I am sure that OCing to 500 by default is draining the battery faster.
I would rather a usable phone than a fast one...(although it still seems very fast to me)

[Q] Phone performance

I wanted to investigate the sporadic freezing in my Galaxy S2. So, I turned on, show CPU usage under the developer's options in ICS. For reference I'm currently running Jedi Knight's latest rom.
I have attached a picture of my cpu usage while at my home screen. The number I've read to be average loads, and anything over 1.00 means trouble. I'm consistently over 10 for my one, five, and fifteen minutes averages. Also, my red bar which apparently measures time in kernel, sometimes spikes and correlates with a brief moment of unresponsiveness.
I've only seen two other screenshots and both users were under two. I was curious what everyone else's loads were. Also, let me know how frequent you have brief freezes, what kind of background apps you usually run. Include info like how many activities do you allow to run in background, do you force gpu rendering, etc. I can't wait to see other's results.

I got like 9/10/11 on mine. I always suspected that I have unusually bad battery life no matter what ROM I'm on, now I wonder if this has anything to do with it...
I'm on Eugene's Plain Jane ROM, which is an AOSP ICS ROM. The Manage Apps menu shows about 10 processes running. Force GPU is on.

Thanks, for the response. Do you ever experience temporary freezes? My goal is to figure out if my mini-freezes are caused my memory or CPU.
Sorry for the bad picture quality. I posted through the android app. Anyway, I've left my phone alone for 15 minutes, and I got 8.7/8.7/8.7. I wonder if this uses a different scale than the Unix scale.

That's normal. The only roms I know that work 100% smooth are Jelly Bean Roms on OFFICIALLY supported devices like the Nexus S and Galaxy Nexus. (Yes the Nexus S runs smoother than this phone. Not faster, smoother) but what OP is stating isn't normal in the least bit. My advice? Ditch that rom. I've never experienced such high CPU activity on any rom and its bad news. Your phone will eventually overheat and shut down. Never a good thing when the SoC gets no form of cooling.

So what do you do when CPU activity is still showing well over 1.0 (5-9) even after installing a fresh ROM? I just flashed the latest official CM10 nightly and have not installed anything other then gapps, and cpu usage is showing 9/8/5.

I experience the exact same thing as ToastMan. My device always runs cool except when have multiple, heavy-use apps open for an extended period of time. My cpu usage percentages and used memory is always reasonable. Could it be something like an incompatible kernel? What are some debugging steps we could take? What kind of information would be valuable to you that we could provide?

Is there a chance that maybe the reading is just wrong? Or maybe normal values on Android are different?
If several other people could just check their results and post them here it will be very helpful.

I was also thinking that it could be calibrated differently somehow. Like, if it was off by a factor of ten. My values would be much more reasonable. But I have seem several screenshots in the 1.0 range.

Min has always been in the area of 9/9/10ish. My screen has never stuttered not even on GB, no rrs or sods on official cm10 so far either. My battery life is an entire day (16hrs) of listening to music/playing emulators nonstop.
Make sure you have the 2 idle processes in your battery. If you don't then your phone doesn't idle which will kill your battery life.
If you are using cwm non-touch make sure you use dark side tools or upgrade to touch recovery (cwm 6.x.x.x or TWRP... my favorite). Reinstall your ROM with a complete wipe, install gapps, boot it up then wait 10 mins before doing any setup.
If you are idling then look at your batt stats again... screen is probably waaaay up there... play with your brightness settings.
Hope this helped

[Q] KT747 Kernel Help

Alright so I am using KT747 Kernel with Ktoonservative/Noop, 1512-384mhz, screen off 486mhz. I was given an option to Lock frequencies which disallows apps to modify the speed. However I noticed after I checked this some of my apps started crashing. I want good battery life (forget to mention I undervolted) and want to know if locking frequencies is what is making the apps crash. Any help would be great, and feel free to post some good settings for the kernel for optimal battery life with pretty decent clock speeds as well. Thanks again.

If your apps crash it is more likely to be caused by your undervolting.
And for the setting go there:

Yeah I read your post earlier in that thread and was using your settings. I've come across a newer problem, my phone randomly reboots. I don't know what was causing this so I restored default settings.

When you change kernel or kernel setting it is usual that your phone may need a few reboots before stabilizing
Sent from my SGH-I747 using xda app-developers app

Unlock the frequencies and run the app that causes the reboot. If it doesn't reboot that was the problem. More likely its too much under volt. The table in the link is some pretty severe undervolting. 740 is a long way down from the stock 925. That's great if your phone can handle it, but can cause problems if it can't. Piece of advice, never use any set on boot settings if your not sure it will. You may find yourself in a bootloop and have to reflash the kernel to get out of it.

I doubt locking the frequencies has anything to do with your reboot problems, this simply dissallows any apps that are capable to override the voltage settings for any particular frequency step. In fact, unchecking this may actually give you a false positive of it 'fixing' the problem when it is actually just using the default (or higher) voltages, burning up more battery in the process. As mentioned by jethro and liltitiz its more likely your UV settings, keep playing with them until you find the happy spot (works on other things too....:silly.

Or just move the ktweaker apk from the /system/app directory from a recovery based file manager. This will keep it from launching on startup and then can either be moved back or ran to reinstall. This way you dont have to cleark the dalvik cache, which should be done any time a kernel is installed, eliminating the extra long boot time when this is done. Either the built in TWRP explorer or the Aroma File Manager which can be 'flashed' in recovery. It doesn't actually flash anything, just unpacks, runs, and then is dumped from memory on reboot...very handy if you dont have TWRP or can't get into android.

Governor issue (??)

Hi!
I noticed that in my Tab Pro 8.4 right after turning it on, when I'm not doing anything and just staring at the monitor it let only one core on clocked at 300MHz (using dashclock CPU information extension). So far so good.
The problem is that after some time, in the same context (doing nothing staring at the homescreen) it let two or four cores on clocked at 1497, so I have to reboot in order to save battery.
Any ideas why this is happenening? Does that happen to you?
P.S.: Battery saving settings turned on

It's mpdecision bug - needs root to fix
This issue should be affecting all stock ROM users of TAB Pro 8.4.
I noticed it a while ago and recently had some free time. The issue was narrowed down to Samsung's buggy mpdecision binary in /system/bin and you need root access to fix it. There are two ways to do it (you'll need terminal and file manager with root access rights):
1. Open terminal, type "su" and then "stop mpdecision". Open Root Explorer, navigate to /system/bin and rename "mpdecision" file to something like "00mpdecision". Reboot. All cores will be running at 300 mhz when idle and tablet will feel noticeably smoother and faster. I did not see any serious impact on battery while running this way for 2 weeks already.
2. Download attached mpdecision file from CM11 modrianwifi ROM, unrar it and transfer it to your tablet. Open terminal, type "su" and then "stop mpdecision". Open Root Explorer, navigate to /system/bin and rename "mpdecision" file to something like "00mpdecision". Copy new mpdecision file into /system/bin, change ownership to root:root and access rights to rwxr-xr-x.
Reboot. The issue will be resolved for good and unused cores will be shutdown properly. Tablet will feel the same way it was before file replacement.
Hope it helped.

Hm I'm not seeing this issue on my tablet running the NK1 firmware, though I think I do remember it happening on the AND3 Firmware (saw it under Android Tuner) , I wonder if it was fixed under NK1, I'm curious too - do you know a easy way to reproduce it?
Here is a screenshot of CPU-Z, my tablet has been running for at least 1 day without a reboot, and had some 3D games run on it etc, CPU cores always seem to fallback to offline and 300mhz under my test
On a side note:
I don't run the Samsung Touch Wiz Launcher I am using "TSF Shell" as my Launcher, and have disabled some Samsung apps like "My Magazine" and a few Knox things that run in the background. also I don't use too many widgets since I found out they can hog CPU esp on poorly written apps. ,

I saw this issue on NA1, ND3, NG1 and NK1 firmware. Initially I thought it was fixed in NK1, but it came back in 3 days after last reboot. I'm running heavily de-bloated rooted stock f/w (Knox is at 0x0).
As for reproduction - I was suspecting Flipboard, but the issue came back after its uninstall as well. Seems to be uptime-related. 1 day uptime is not enough for NK1 - please check after 2 more days.
I'm running TouchWiz, but used "MyAndroidTools" to disable several services and startups for few remaining stock widgets and apps. Now I'm totally happy with my Tab Pro - best tablet I've ever had.

Hm I'm not seeing this issue on my tablet running the NK1 firmware, though I think I do remember it happening on the AND3 Firmware (saw it under Android Tuner) , I wonder if it was fixed under NK1, I'm curious too - do you know a easy way to reproduce it?
Here is a screenshot of CPU-Z, my tablet has been running for at least 1 day without a reboot, and had some 3D games run on it etc, CPU cores always seem to fallback to offline and 300mhz under my test
On a side note:

This issue should be affecting all stock ROM users of TAB Pro 8.4.

Thank you! I've replaced my /system/bin/mpdecision file with yours and so far the tablet is working properly.
I'll know in a few days if it sticks. But, I definitely had this problem with the governor with T320XAR1ANK1. FYI, for what ever it's worth, I've noticed this governor is slightly slower to ramp up. I don't really care, as the tablet is still super responsive, but some may also notice that Antutu and CF-Bench scores are slightly lower with this governor.

Yeah I can confirm its still present in K1, I tried to limit it down to a few things that could be causing it but have been unsuccessful sine it occurs at random it seems
but my thinking its either something to do with
1. video decoding (I watched a few videos) .
2. charging the tablet (I noticed on my ampere cable it was drawing 0~70 - 120 mA idle )- but this could be because cpu was already drawing more power then needed, usually it's 0 ~ with an occasional 30 mA when plugged in with screen off.
3. possibly game / 3d
...anyways I switched the mpdecision file and it seems to work fine now, except for a slower rampup speed like the others said - not really a big deal i'm sure this will help battery life too.

Hi!
I noticed that in my Tab Pro 8.4 right after turning it on, when I'm not doing anything and just staring at the monitor it let only one core on clocked at 300MHz (using dashclock CPU information extension). So far so good.
The problem is that after some time, in the same context (doing nothing staring at the homescreen) it let two or four cores on clocked at 1497, so I have to reboot in order to save battery.
Any ideas why this is happenening? Does that happen to you?
P.S.: Battery saving settings turned on

WOW! Finally someone on this forum other than me noticed this issue
I think I posted about this issue in September or so, and nobody else here said they noticed anything. Then I stopped checking this forum regularly... I'm glad to see others have now noticed this problem and have even figured out the root cause too!
