[HTC One V] mysdavey:
Check the battery usage through Settings > Power > Battery use.

No need to use a third party app for this (unless you've removed this by any means).

Sometimes software issues cause these problems on the phone (even on the stock ROM). Common culprits are "Phone is idle", "Inactive" and "Android system". If these are reporting battery use above ~10% (and you haven't actually had the phone inactive for most of the time), the problem should be resolved with a factory reset.

Otherwise, unless you've tampered with the bootloader this would be covered under the 24 month manufacturer's warranty (12 outside EU) and the device should be sent in for a battery swap / given back to retailer as DOA.

Also, the device isn't the fastest one. The processor is running at 1Ghz with 512Mb of RAM to go along with it. The solution is to load a kernel with overclocking capabilities (Titanium for example) and crank up the CPU to 1,5 or 1,7 GHz. I would assume all of them can run 1,5 GHz as I suspect the processors are actually underclocked to keep battery life long.

Obviously this would reduce your battery life, but having less than 24 hours of battery life on an unmodified One V is what I would call poor unless you are a heavy user.

I hope this helps.
[HTC One V] 1ceb0x:
Actually, a good kernel can improve battery life even if you overclock your cpu. HTC's kernel doesn't come with all the tweaks available for volting and battery life. So if a good dev makes a good kernel, the battery should be the same as running on stock, but with faster performances. Adi_Pat has done a great job with his kernel. I was running it for 2 days until I needed to get a replacement for my phone and now I am waiting to get a new one so I can run it again. I even overclock it at 1.9 ghz and run it for 1 full day and after almost 8h of wifi on, the battery still had 50%. So if you don't have an app that kills your juice, you have definitely a poor battery built in.

does it lag

it was going to buy this phone but saw this vid /watch?v=JptIYZl8qmE that said it was very lag. do you think i should buy this or the sony arc s. plz help
[HTC One V] fisterkev:
I had some similar issues until I did the following:

Run the battery completely dead until the phone shuts itself off, then put it on the charger with the phone off. Charge it until it is at 100%. Take it off the charger and turn it on. Turn it off again, put it back on the charger until the LED is green, then turn it on again. This helps Android to calibrate the battery.

Install Quick System Info and see what apps are running and how much resources they are using. Also, close all apps, then go into Settings>Apps>Running and see what is running. Look for any apps that shouldn't be running and uninstall them. You have something running in the background and need to get rid of it, this will help you do that.

Uninstall Swiftkey X or Thumbs Keyboard or any other keyboard apps you put on there. Uninstall any weather/clock widgets like HD Widgets or Animated Weather. Use the stock keyboard and stock weather widget (they both work pretty well).

After doing all of this I consistently get home after 10 hours from work with about 60% after moderate usage. I also have almost no lag unless I am playing a more graphically intensive game. Couldn't be happier.

[Wildfire Q&A, Help & Troubleshooting] tophatmonsters:
Sory man your stuck on seven for now. you can update to cm7.2 if that what you want but you have to do it the old fashioned way download it to an sd card and flash it.

good luck

Hello you DualBooters and Triplebooters out there!

SDCacheMount for SD-Roms

Well, this idea came to me because many users of my triple-boot SD were getting tired of the rebuilding of system-cache when every time they had to switch between roms. What I have here is a small script that will install to /system/etc/init.d The script will run at boot time and create a 100mb .img file to be used for /cache. This way each rom will have its own dedicated /cache partition so to say. This will also benefit anybody that dualboots (eg. EMMC / SD-Rom). I've prepped two different versions. One for my triplebooters out there and the other for anyone running a rom off an SD card.

Things to note:

-This will dd a 100mb .img file to your /sdcard partition of your sd-rom on first boot. What this means is that before the system progresses any further the img file needs to be created so that the /system can use it as the /cache partition.

-It will sit at a black screen for up to 1 minute possibly. So please be patient!!!

-The dd'ing of the .img only happens on first boot. So once the cache .img is created. Boot time will be normal on successive boots.

-Make sure you have enough space on the /sdcard partition of your sd-rom.

-So for Dualbooters you will need at least 100mb free

-For Triplebooters you will need at least 200mb free

-Now you can switch between EMMC roms and SD roms without having to wait for /cache to rebuild every single time.

DOWNLOAD:

DUALBOOTERS ( EMMC / SD )

**You should be able to flash this from a standard CWM Recovery or rename the .zip file to begin with "update-" for Verygreens method.**

TRIPLEBOOTERS ( EMMC / DUALBOOT-SD )

**You should only use the CWM Recovery that is included with my Dualboot-SD**

Big thanks to:

DizzyDen for helping me out with the script

Shumash for troubleshooting it for me

Inportb for some guidance

HacDan for his sense of humor :p

Hope this helps a few of you Nookers out there!

Reserved?! :D
[Nook Color Android Development] ahfo:
Great job! gonna have a try on this
[Nook Color Android Development] RASTAVIPER:
So the main advantage of this script is smaller booting time?

And this is the case when you switch Roms only between emmc and sd or also 2 different roms from same sd?

Unleashed from my Nook Color at 1.2G
[Nook Color Android Development] DizzyDen:
The advantage of the script is that each AOSP will have its own dedicated cache and not all be utilizing the same space for all the cache.
[Nook Color Android Development] shumash:
The most obvious effect is that booting between the various ROM's is seamless (except for the minimal wait at the blank screen) and fast. It makes switching between the AOSP's very easy. The less obvious, behind the scenes effect is as Dizzy describes.

It should be noted that if you flash an updated or newer ROM, you will also need to reflash the SDcacheMount.zip.
[Nook Color Android Development] racks11479:
Yes correct, thank you. I'll make note of that in the OP. Also note that once the .img cache is created, although you have to reflash the SDCacheMount after flashing a new rom. It won't have to create a new .img. The script will detect if one exist already and if so, proceed to boot. But if you don't flash the SDCacheMount right after flashing the new ROM. /cache will default back to /emmc

Recently I've been having problems with my Sensation4G screen, The area where the letter d on the keyboard appears is unresponsive and when I'm texting/unlocking the phone the pattern completely messes up cause it skips to the letter/dot next to it, anyone knows why this is happening?

Also my phone has extremely low RAM available lately, and it lags a lot
[HTC Sensation] k0zmic:
How much RAM? And what ROM are you using?

Not sure the exact problem but I had a similar issue with my HTC Hero. It was due to the digitizer being faulty.

I wouldn't think it's the digitizer if it's just in one little area though, still a possibility.

[Eee Pad Transformer Android Development] RaymanFX:
This is the restarted thread of my ICS Kernel

-

Codename Harmony

​

Current features are the following (more will follow) :

EVERY firmware avaiable is supported ! This means you can use my kernel on every ASUS-based roms like Revolver, Frozn or ARHD, but also on AOKP, CM9 Nightlies, Megatron, EOS, CNA, TEAMGUMMY, and all other AOSP-based roms out there.

Full 3G support on roms which support 3G

Stable Overclock up to 1.6 GHz

Stable GPU - Overclock ! -- Better 2D and 3D performance !

This is a HV (HighVoltage) Kernel. This means voltages are increased, but I use lower voltages than guevor does.

Extended File System support : Full CIFS, JFS, XFS, NTFS and REISERFS Support inbuilt in the kernel - no need for modules !

Added back missing powersave governor. This is nothing useful other than setting up profiles in setcpu, powersave governor for "screen off" profile does make much sense here.

Added Deadline I/O Scheduler for fancy testing.

Added Simple I/O Scheduler for ultimate I/O performance.

Readahead tweak for massive I/O performance boost.

Added minmax, wheatly, intellidemand, lagfree, smartassv2 governors.

That's it for now. You shall know I'm always open for user's request and will do my best to implement things from your wishlist if others and I do approve.

giving the kernel a run out now......smartassv2 with noop is blazing for web browsing! works pretty awesome with smartass and deadline aswell.

tried to change to interactive with noop and the tf locked up and i had to force a reboot......il see if i have logcat and post it up.
[Eee Pad Transformer Android Development] cholywell:
Will this work with AOKP? I think build 38 switched to the nl80211 wifi driver and the wifi won't work on custom kernels.
[Eee Pad Transformer Android Development] RaymanFX:
Yeah, I encountered this as well, but I couldn't see any kernel panic in this, might be something else.

My next goal ist to port the linux 3.4 kernel, as they already included android source code in the mainline branch. Thsi would take the kernel to the next level.

But most of my worktime still goes into this kernel :)
[Eee Pad Transformer Android Development] RaymanFX:
You're absolutely right. Everything will work fine except for wifi. If more users want this, I will make a aokp version with different wifi driver.
[Eee Pad Transformer Android Development] cholywell:
I think a CM9 AOKP version would be very popular. I don't think there any custom kernels for those roms and all the ones based off them.
[Eee Pad Transformer Android Development] scottyf79:
+1.......the Cm9 builds like Skank etc could do with some loving :)
[Eee Pad Transformer Android Development] RaymanFX:
Did you try some cm9 rom with my kernel ?

I'm not aware of them having changed the wifi driver to something other than bcmhd...ko , in other wirds, asus stock.

Correct me if I'm wrong.

I'm on a trip the next days, so I will be able to continue work on this kernel let's say.. next tuesday if everything goes well. Just tell me which wifi driver to use and I will compile it :)
[Eee Pad Transformer Android Development] scottyf79:
ok ive just tried Skang (cm9) and Gummy (aosp/cm9) with the kernel and neither connect to wifi. also when i tried to change the cpu speed with the baked in cpu controller i found they auto reverted back to 1000mhz with interactive and would not stick on 1200mhz or the selected guvenor.

I'll ask the respective devs what may be required to fix.
[Eee Pad Transformer Android Development] sert00:
thanks for the work..i'm not going to test it due to stocked tf before assistance centre sending,but when i'll receive back my tablet,i'd love to be able to try this kernel...for my taste,i'd love to see wheatley governor inside..for me it's a very efficent governor.think about that mate.cheers and keep up the hard work!:)
[Eee Pad Transformer Android Development] RaymanFX:
A little update in the meantime : Beta6 is ready, added fully working sio-scheduler and hotplug governor. There is a bug because of which hotplug gov is rebooting instantly after being woken up from deep sleep.

More changes are :

Improved smartassv2 governor, working almost perfectly now !

Improved minmax governor. Ths does now work, but actually needs some further love from me, I think.

Will update the thread next week, along with Beta7.

Beta6 currently avaiable at : http://db.tt/XSK0na2Y
[Eee Pad Transformer Android Development] atomic339:
What about version for AOKP? All kernel brake wifi on b38
[Eee Pad Transformer Android Development] RaymanFX:
Seems like I miss my own deadline.

Beta7 will be avaiable in a few minutes.

Random governor lockup while changing in setcpu or nofrills etc. should be fixed now.

I also improved all governors balancing and fully fixed the minmax governor.

Added sio scheduler to get the best I/O performance possible.

I will have a look on an AOKP and CM9 version with enhanced wifi drivers next week. Stay tuned !
[Eee Pad Transformer Android Development] zdalin2003:
Hi and thanks for your work.

Here's my experience with BETA7

TF101 b50, always docked with microsd always inserted

rom: revolver 4 rc2, kernel: harmony beta7

I tried your kernel after a long time using guevor's v20, because v20 gave me SOD after 3-4 days of normal operation.

I just wiped cache and dalvik, and then flashed beta7. It seemed to work smooth enough - had some stuttering in Modern Combat3, but that went away after a few minutes of playing.

The major problem was that it just RR while i was in a fring video call. Talking, as usual and then just bam! speakers started making this weird clicking noise for 1-2 seconds, video froze, and my tablet rebooted. This never happened before - i actually didn't have the RR problem even on stock rom+kernel.

I decided to test it overnight, only to wake up and see it rebooted again. It wasn't charging, it was only docked.

The good thing was that battery consumption was good ~1% per hour, with wi-fi on. It goes into deep-sleep, but also, before it does that, it does some random wake-ups.

So here's a summary of MY experience with BETA7 kernel

PRO's:

- no SOD

- good battery life (~1%/hour with wi-fi on, in deep sleep)

CON's:

- Random Reboots

- some random wake-ups

- some stuttering in 3d apps that seems to be loading-related

I'll be going back to guevor's, but i'll definitely keep an eye on this one.

Sorry, i didn't think of saving any kernel logs...

Keep up the good work!

Kernel based on Asus 9.2.2.4 ?

Hi,

is your kernel based on the Asus 9.2.2.4 stock kernel?

Because I've a TF101G 3G model and this the only kernel wich is stable (for about a week no RR or SOD's at all) on this tablet version while using Wifi and 3G functionalities.

BTW I'm using ARHD 3.3.1_3G rom.

I would like overclock it but this is not supported which the stock kernel.

Many thanks in advange.
[Eee Pad Transformer Android Development] RaymanFX:
Random reboots are definately rom - related, try ARHD rom, has been the bost rom ever for our transformer, I always put my trust in it. Revolver is halfway abandoned, outdated and not frequently updated.

Random wake-ups are rom related, too. I do not encounter any of your errors, sorry.

Maybe if you could get me a kernel message (kmsg, google it) , I could help you.
[Eee Pad Transformer Android Development] RaymanFX:
Kernel is based on 9.2.1.24 . I haven't found any newer source on the asus site, but you may redirect me to it, then I will use it.
[Eee Pad Transformer Android Development] dragon_76:
I have my clock at 1.4 and I have a 32GB class 10 pny uSD I never remove. I've never had any problems. In another thread someone mentioned having problems with Guevor's kernel when using their uSD. I think it is a problem with early model trannies. I have an SBK2 B80 and I have never had any hardware issues at all. I would bet that the Asus kernel uses software to fix these hardware bugs, probably related to timing.

[Eee Pad Transformer Android Development] xxbrentonxx:
How is the increased voltage on battery life and life of the device in general? Thinking of using this with a custom rom (probably Megatron) and maybe overclocking to 1.2ghz (it does scale, right?) but im new to Android so not sure about all this stuff.
[Eee Pad Transformer Android Development] scottyf79:
battery lifes good - cant say ive noticed any major difference even when running above 1.4ghz.

scaling works so no worries there. im using intellidemand @ 1.5ghz - performs really well.

i'd suggest running it with Gummy rather than Megatron......purely just because its more up to date, will still give you lots of tweeks to play with, stable and fast (plus the added bonus of nightly builds)

just uploading the latest nightly mirror now.....and as above theres a link in my sig to the latest Harmony.

Note: Any keyboard issues with Gummy, just flash the Asus keyboard zip & remember to flash Gapps
[Eee Pad Transformer Android Development] xxbrentonxx:
Ok thanks, that sounds good would you reccomend the latest nightly you posted in the thread? I'll have to look into putting the stock apps back on because I want the live wallpaper, polaris office and probably asus file manager + other stuff - most of them can be put on either way i guess though.
[Eee Pad Transformer Android Development] scottyf79:
latest nightly recommended (available on last page of Gummy thread) and im sure some of the Asus apps were made as flashable zips in the app section but i could be wrong.
[Eee Pad Transformer Android Development] xxbrentonxx:
Yeah, i've seen a few around but i believe file manager only works on Megatron and ASUS based roms. I'm sure there will be a good alternative somewhere though.

How would I access the GPU overclocking aspect of the kernal...or is it a static OC? Thanks in advance!!!
[Eee Pad Transformer Android Development] momothecat:
If you using Megatron ROM, there's an over clocking app in the megatron part. If you use ARHD or Revolver, download setcpu or system tuner or others apps (there are alot)

You can only overclock your cpu using custom kernel, not stock kernel

Hello all! I've been using Harmony rev03 and Steel Droid and I'm wondering what setup gets you the best performance.

I use this mainly for web browsing and reading pdf's so that's how I based my judging of total speed. Any particular setup that provides the best performance for large, memory intensive applications such as loading a 250+mb pdf files?

Thanks

Thanks for the work rayman33.

I tried a lot of stock kernels before, but all were giving me random reboots.

Tried some of Guevor's kernels as well, but my tablet was randomly freezing.

So far it is stable with yours. Really appreciate the effort you put, I was starting to get a bit mad at the situation.

Before this kernel, not even nvflash to honeycomb got rid of the reboots and freezes.....
