Hi people.

I wanted to ask you whats your battery usage and life when you use your phone ( not in standby ). I got a bit big drain when i use Mobile network and surf , or xda app for example..

Can you tell me your exerience?

Thanks in advance

Uhhh... I flashed 1.4 on a Sense 3.0 ROM (ARHD 3.6.1) and it's working fine.

Should I be worried my device is gonna blow up?
[HTC Sensation] mudhi:
My experience is no matter what kernels or roms, web surfing or simply the usage of gprs on 3g network drains out battery very quickly, even more quickly than playing games, this also applies to other OS and model like I had before,HD2. Unfortunately there is no fix except don't use it.

This post cost me 10% battery. :D
[HTC Sensation] V6-Maniac:
Whats your idea of a big drain?

Mobile data is by far out a battery killer.

Two days ago we were playing wordfeud for 6hours before the Batt died.

In the mean while got twitter, 3 gmail accounts and was using whatsapp the whole time.

This is a normal usage to me if you use it heavily.

But true daily use like you would use your phone.

- Some calls

- SmS

- Whatsapp

- Twitter

- Some emails

I can get aprox get 2 days out of my battery.

But how is your mobile network coverage?

Bad coverage will also kill your battery.

Edit:

Looking at my HTC Desire (Pica somewhere in this thread) ran for 10days

Only the radio was so i could make phone calls.

Installed no 3th party apps so it couldn't sync.
[HTC Sensation] Laynee1:
Thanks mate

So Wifi drains less battery than 3g?
[HTC Sensation] show-p1984:
Nope, but you might experience some rnd reboots / wakeup problems etc. If you don't experience them, use it that way. If you do experience them: I do not support 1.4 on sense 3.0 ;)

Ofc...

Just explain it logically:

How far is your phone away from your hotspot?

&

How far is your phone away from the nearest cell tower?

I would guess the battery usage is doubled or tripled for mobile data.

#############################

I have identified a small issue in 1.4 which did only present itself in the AOSP version. I will implement a fix for this in the Sense version as soon as I am confident that it is stable for Sense.

This may be the cause for some incompatibility with Sense 3.0 and also it may be the cause for the camera problems only some ppl are experiencing.
[HTC Sensation] sniperde:
You will implement the issue ? ;)

Just a joke :D

Running 1.4 for a couple of days, no reboots, less battery drain than with 1.2.

Man you are a god ...

For me, WIFI causes a higher battery usage than mobile data (EDGE or HDPA).

But it is low anyway, I am talking about 1% an hour.
[HTC Sensation] show-p1984:
Edited my post -.-"

Well we are talking of battery drain while _using_ your data connection. Mobile data will use less battery than wifi in standby but it will really suck your battery whilst using it.

Regarding the issue:

Only a few users are experiencing those issues, and I can't exactly tell why, probably because there are two Sensation versions with different hardware (regarding the display, etc). Whilst one version will have no problem, the other will as it seems.

Also make sure that you clear the app data and cache of the camera app if your are experiencing problems, this will fix all issues for 90% of the phones.
[HTC Sensation] Laynee1:
How the hell you manage to have 1% per hour while USING your phone with WIfi or mobile data ( surfing and stuff ) ?
[HTC Sensation] V6-Maniac:
It's just a fact. :D

If have my WiFi on the whole day and only turn the phone/screen on when i receive a message or tweet.

It uses just 1 to 1 1/2% per hour.
[HTC Sensation] sniperde:
Using? I am talking about "let the phone rest with connection on", so no active Display :D

If I turn off the radio (airplane), battery drops about 2% for more than 10 hours of idle time. This is what I call great standby battery life.
[HTC Sensation] mudhi:
Is the speed of mobile data affected by kernel? Or something else, I never reach speed above 3mbps although operator said is 7.2 mbps.
[HTC Sensation] ziggy1001:
In my experience what network providers say they "provide" and what you actually get two entirely different things. Too many variables involved
[HTC Sensation] Gunkk:
*#*#4636#*#* try different radio settings to save power, e.g. gsm auto prl.

Sent from my Bricked Energy Sensation.
[HTC Sensation] ziggy1001:
For me 99% of the time phone is GSM only and sticks to lower consumption 2G and only gets switched to GSM auto (PRL) specifically for faster but battery draining 3G usage
[HTC Sensation] undercover:
Hm? It's other way round IIRC. I mean it sticks with 2g instead of scanning for 3g signal constantly while on gsm auto prl.
[HTC Sensation] ziggy1001:
Not on my network;)
[HTC Sensation] Laynee1:
So, to use GSM only or gsm auto pr to save more battery power?

Autonomy is a good quality :rolleyes:;)

Bricked v1.45 test:

[Beta 1, Build #405]

Should work stable now on Sense 3.0 & Sense 3.5.

(yeah I think I found the issue)

Download: Click me

(meant to be used with the modules from v1.4, that's why it identifies itself as v1.4 ;))

---------------

I am currently rewriting some parts of the KGSL driver. If everything works out as it is supposed to, we will have a more efficient code (improves performance and reduces battery usage)
[HTC Sensation] Darnell_Chat_TN:
I have occasions where the data connection will cut out. I don't know if it has anything to do with Bricked though. I've found that closing and opening the Mobile Network connection fixes it.
[HTC Sensation] ziggy1001:
#405 working fine here... so far:D;)

RCMix 3.5 v09
[HTC Sensation] immunityx:
Same here with ARHD 3.62
[HTC Sensation] show-p1984:
That sounds better and better ;)
[HTC Sensation] tinker2000:
No issues for me yet either.... 405 build and IC3.3.9. Thanks :D
[HTC Sensation] show-p1984:
Well ic339 is sense3.5.

There should have been no issue with #404 (release v1.4). ;)
[HTC Sensation] tinker2000:
I get no issues with any of them Show :)
[HTC Sensation] krogoth:
Good to hear about new progress :)

How about ZSL drivers? Any news or progress? :)
[HTC Sensation] show-p1984:
Yes:

$§%$#§%&§$#§$#$§ HTC!

:D

I tweeted them 2 times, sent 5 support messages... No response at all! Not even a friendly: "No we are sorry we can't publish beta source" No word. That's no way to treat a customer.

To my own reverse engineering process:

ZSL working with exceptions. I am now able to capture one action. That means Cam app starts -> capture (with whatever settings) -> preview -> 2nd capture -> crash

Somehow HTC changed a lot on the Sensation. I gave my ZSL code to a friend, who patched it inside his doubleshot kernel, it works flawless. That proves that something very wicked is going on here.

Maybe someone can get an HTC guys to listen to a friendly request of "leaking" the ZSL drivers and any other changes they made connected to that ;)
[HTC Sensation] Darnell_Chat_TN:
Maybe you should offer them lessons on how to write a good Kernel in exchange for the ZSL drivers and related code :D .
[HTC Sensation] stev32k:
This is really weird. I just installed 2.6.35.14-bricked-aosp-v1.4-ondemand-1536-192.show and the airplane mode is flashing on and off and will not let Wifi connect.

I have the (mike1986) ARHD 3.6.2 ROM and the recommended radio installed. I installed this kernel because I was having problems with GPS. It cured the GPS problems, but now I can't use wifi because the airplane mode keeps cutting it off.

HELP!
[HTC Sensation] KingDavid63:
dude you flashed the wrong kernel... you flashed a cm7 kernel.. aosp... not sense.. try again..
[HTC Sensation] stev32k:
Thanks, I was just following instructions - bad on me.
[HTC Sensation] mudhi:
+1 :D

Every developer has different attitude, but I like showp most, which best fits customer needs... :D

xTC didn't follow the opensource spirit, and infact they broke the rules. If I were the developer of the xTC kernel, I would release the source immediately, so that I could benefits from those who improve it.

BTW, is there a simple way for dual boot like grub? so that I could just boot stock kernel when I want to use burst mode, and Bricked 1.4 for others?
[HTC Sensation] arachnid1970:
Thanks for the latest versio, show... works great on RCMix 0.9. By the way, beside the kernel i like the way you manage your threat and give feedback to postings...
[HTC Sensation] KCuadrado:
This is the best kernel, but I still have the same problem since 0.9. Whenever someone sends me a video in whatsapp messenger, after it finishes playing the phone freezes. The same thing in the YouTube app, after finishing a video, instant freeze! Then I have pull the battery out.

[HTC Sensation] arachnid1970:
ehmmm... maybe someone can tell me how to flash that zImage... tried it with kernel update utility, but it doesnt show me "next" after chosen the image...
[HTC Sensation] ivicask:
Simple replace zImage inside Bricked-v1.4-ondmnd-1536-192.show-p1984.zip (kernel->zImage)

Or you can reboot phone into fastboot and from ADB:

fastboot flash zimage zImage
[HTC Sensation] the_real_fosgate:
Hi,

a question from a noob ;-)

When I flash your kernel (1.4) fro Example on Baadnewz Rom, without any

OC tool on it, do I have all advantages of your kernel, except OC and UV?

Is the kernel going down (MHz) when the screen is off?

Thank you & bye bye

Robert
[HTC Sensation] arachnid1970:
Lots of thanks,, mate... helped *g
[HTC Sensation] mudhi:
It should be rom issue, v0.91 worked flawlessly on 2.3.4 stock Rom,. Use. > v0.91 for sense3.5 GB2.3.5.
[HTC Sensation] show-p1984:
Try the latest test a few pages back.

Btw: You don't need to pull battery. Hold down VOL UP/DOWN and POWER for 10 seconds, the phone will reboot. (Like the reset switch on your pc)

Ofc you get the advantages, and yes it goes down if screen is off.

What the hell do you guys think those OC apps do? They simply set values in kernel provided files, which will change kernel settings. Nothing more.

(Which you can do by yourself from the Terminal too)

There is just a UI wrapped around the commands that set the values you choose...

(For the default clocks, please look @ the OP)
[HTC Sensation] V6-Maniac:
You posted in my thread to, right?

So is this happening on my rom or like your sig says Incertcoin?

If it's on my rom, have you installed the latest flashplayer from the market.

If not please try that, my freeze was solved when flashing the latest Adobe flashplayer.
[HTC Sensation] dingolino:
@show

>Btw: You don't need to pull battery. Hold down VOL UP/DOWN and POWER for 10 >seconds, the phone will reboot. (Like the reset switch on your pc)

This is a helpful tip!!

Never heard about this feature (which is off course no excuse :D).

Even so if this tip is already in the Q&A (what I do not know) maybe you can add to your 1st post that it is not getting lost within the thread

Best regards,

[HTC Sensation] tinker2000:
Hi,

When you flash the bricked kernel, it will run at the processor default speed of 1.536GHz, as Show-P set it. It will also have the on-demand governor by default. This is how Show-P uses his phone and it should cause you no issues as long as you steer clear of the burst mode in the camera.

You can easily use FauxClock v0.75 to set your frequencies with screen on and off, and if you want I have an undervolting table you can plonk in your /system/etc/init.d/ folder that will give you a little more battery life and still be stable. Link: http://rootzwiki.com/index.php?app=core&module=attach&section=attach&attach_id=9620

Hope this helped, I'm in a good mood today....my daughter swam a little today, albeit like a drowning rat, but 1/3 of a width is a start...proud Daddy :)

@Show-P: Sorry, didnt see you had already replied :)
[HTC Sensation] Darnell_Chat_TN:
I don't think so.

So your best option would be to get ROM Manager and flash back and forth as needed.

Given the Bricked 1.4 cam fix, when you flash the stock ROM, I don't know whether you'd need to reflash the Amaze Mod again.
[HTC Sensation] tinker2000:
or you could use 4Ext recovery control and switch between your TAR recovery backups.. Either way I suppoose.... I do that anyway
[HTC Sensation] Astug:
You rock man! I was waiting for a stable 1.4 for Sense 3.0, def going to try it out! The 320MHz GPU version is also very much appreciated. ;)
[HTC Sensation] ziggy1001:
Thanks:D:D

A rom can only be as good as the kernel it works with so a small well deserved contribution :D

Just flashed 1.4r 320 and it simply rocks!!

the combo Baad - Show is simply the best :D
[HTC Sensation] ivicask:
v1.4r1 with 3.5 rom got weak up bug while using camera, also noticed it happens oftenly if screen goes off while camera is active, after that you cant turn on screen anymore, managed to reproduce it 3 times in 15mins..But it also happend once without using camera, i just finished phone call and phone couldnt turn on..

View attachment log.txt
[HTC Sensation] lightninbug:
Thanks, was about to flash..maybe now I wait. It appears Fauxs latest sense kernel has the same issue.
[HTC Sensation] show-p1984:
There is no issue.

Flash rom

flash camfix

flash Bricked v1.4r1

if you experience problems: clear camcache/appdata

Profit

Bricked should only be flashed over a stock kernel because I cannot predict what ramdisk hacks other kernels set.

So unzip the attachment and do this:

adb reboot-bootloader
fastboot flash boot C:\Path-to-the\boot.img
fastboot reboot

You are now on stock kernel.

adb reboot recovery

Flash bricked like mentioned above.

Profit.

I am using this kernel as my daily driver (with ic3.4.0). I had no wakeup issues till now. And certainly not that frequent like you described.
[HTC Sensation] ivicask:
Did everything you said in that order, kernel was flashed over stock kernel (wiped cache and davilk before), only thing i didint try is deleting cam data will try that, but i hope i doesnt freeze again randomly on phone call..

Thanks gona report if it happens on anything else than camera.
[HTC Sensation] show-p1984:
I did totally overlook you :o

Thank you very much! :)
[HTC Sensation] show-p1984:
You wakeup issues may also be connected to the amaze cam, which I don't use. I use the stock 3.5 cam, which works flawless.
[HTC Sensation] Laynee1:
Hey ppl :)

2 questions here :

1.Is downclocking to (for example 1.2 or 1.3 ghz) going to help with battery drainage?

2. When flashing back stock camera app from amaze camera , what to do else ? Clear something ? What about camfix i have flashed before ?

Thanks in advance

Laynee1
[HTC Sensation] tinker2000:
When flashing back to old camera, clear cache and dalvik cache in recovery first. Down-clocking will improve battery life. Camfix youve flashed before wont matter. if you then put another Amaze cam version on, you will need to re-flash the camfix
[HTC Sensation] Laynee1:
thanks... ALOT ... again :)
[HTC Sensation] smint86:
if i flashed camfix once (flashed the bricked 1.4 with included camfix from ic addon folder) and will flash 1.4r1 now, do i have to flash camfix again? i assume that i don't have to, just want to make sure.. :rolleyes:
[HTC Sensation] show-p1984:
as long as you don't change anything with your camera you won't need to flash the camfix again. ;)
[HTC Sensation] Laynee1:
Downloaded 1.4r1 and flashed it .. Will see how it works :)
[HTC Sensation] KCuadrado:
Yup, it was me. I'm on InsertCoin right now. Will try your new ROM update for T-Mobile soon. The problem happens in insertcoin but I haven't tested in your ROM. I didn't have flash player, will see through that too. Thanks man.

[HTC Sensation] Astug:
Performance is excellent so far on CoreDroid v2.5 with v1.4r1.

Question tho; How can I tell if my phone can handle 320MHz GPU OC (in other words, what kind of bugs or strange behaviour should I look out for)? I flashed it but so far I've noticed nothing strange or bugged.

Thanks.
[HTC Sensation] show-p1984:
Black screen, reboots, graphical distortions.. the usual.

This is why I have become addicted to this forum,squeeze the most out of my batt. Don't play games...

What prog should I use to tune it down,and how low is the safe number? Understand that every phone is different,but I'm not a phone-coder-geek,just trying to find the best combo to get the most out of it...

Good job with this kernal,favorite topic...read it before the newspaper in the mornings :)
[HTC Sensation] tinker2000:
Hi,

You can use Faux clock or system tuner by 3C. Both work well. Both of these will let you undervolt as well as under clock, although I'm not sure the undervolt works that well on Faux clock. I undervolt with an init.d script. Check my post of a few pages back for the script, post #2249
[HTC Sensation] arachnid1970:
I decided to use system tuner, but more in cause of its other functions... Leaving the Kernel at its settings gave me the best (felt) results, i give not much on benchmarks... UV'ing never gave me me more battery than origin settings...
[HTC Sensation] invisiblebm:
Hi . Now for first time I have decided to use custom kernel. The speed is impressive.
[HTC Sensation] tinker2000:
Will get more impressive than that after a few reboots

So the new briked kernel can be used on a 3.0 rom then?
[HTC Sensation] show-p1984:
Not if you can't read the first and second post. Especially the Changelog.
[HTC Sensation] tinker2000:
Hi Show,

your latest beauty seems more stable with the camera than v1.4...I cant get it to crash unless I do the obvious and select Burst. This latest incarnation is perfect, as I need a nice and stable camera...and like the performance of the Amaze camera. I have no issues with the battery but need a little more time to see the true extent of your demon tweaks

Thank you Mr Kernel Haxxer :)
[HTC Sensation] gilbert11231123:
v1.4r1 is more stable then 1.4 by far i been using it without any freezes in camera using amaze v7 , only one freeze after playing a youtube video, but after that i been watching videos trying to get it to freeze again but can't, great job show this version is much much more stable thx and keep up the great work....
[HTC Sensation] show-p1984:
Well in my current version, snq- and I fixed ~8 errors each of us. (Let's make that clear: HTC introduced errors, which are not only wrong, but influencing the way the kernel should behave, and behaves now through those errors :p)
[HTC Sensation] Gtj94:
Whenever I used bricked kernels my battery drains like mad :(

I've switched around roms, always calibrate, full discharge/ charge cycle. It's definitely not a rouge app

My CPU settings are

384 min 1.56 max

And sleep min is at lowest (198 or something) and max is 480ish
[HTC Sensation] show-p1984:
No app is currently able to readout the exact values. But some have a correction for the sensation installed. You should use it. (options of your monitor app -> current/mA correction)

This value is only an estimate, and not an exact value. Current widget for example throws me sometimes 800mA and while in camera and recording 1080p with flashlight: 1600mA (which would let my anker die in < 1minute)

So it's complete rubbish because my battery lasts >2hrs of 1080p video recording :D
[HTC Sensation] Gtj94:
I'll have a play around with it some more. I really want to stick to bricked just because the performance is amazing in comparison to the other kernels :D I'm currently using battery monitor widget to keep updated which claims to have sensation support :)
[HTC Sensation] TwelveSided:
Just flashed 1.4r1. Amazed at how cool it runs when playing games. Great work!

[HTC Sensation] Gtj94:
the new rc is working perfectly on my own sense 3.0 rom (Y)
[HTC Sensation] TwelveSided:
Yup. Running it on ARHD 3.6.3. Works perfectly and runs very very cool.

However, I just noticed it seems to be missing 108000 as a clock speed.

[HTC Sensation] show-p1984:
Rom thing, not a kernel thing ;)

That's why I posted it over there :p
[HTC Sensation] Lionhardt:
I did :D

Just wanted to hear what other people think. Too close to tell for me on Pyramid3D, i mean that rom is already a beast as it is so its tough to beat. I usually judge by web surfing performance, ui smoothness, and battery life.
[HTC Sensation] ahoslc:
Weird problem

I flash you aosp v 1.4 onto Trips Miui Rom and I get no service. I flash your 1.4 sense version onto it and it's fine any ideas on this?
[HTC Sensation] show-p1984:
Was discussed and answered a bunch of time in the aosp thread. Search for it. And why do you post in the wrong thread anyway?
[HTC Sensation] TwelveSided:
It's hard to tell since the sensation never really slows down but the fact that it runs much cooler than any other kernel I've tried is a plus for me.

Haha sorry typo I meant 1080000
[HTC Sensation] show-p1984:
I cleared the acpu table and threw out some frequencies. (Changelog from v1.3 -> v1.4)
[HTC Sensation] KAwAtA:
Just out of curiousity, is anyone else experience battery issues? My battery could normally go for about ~30 hours -- 40 if I BARELY use it..and recently since I've been using bricked (because it started to work with camera!!) my battery life is down to about 12-14 hours... MAYBE it's me but would like to check if anyone else is having this as well.

As for now, I've reverted back to stock kernel (what I used to get around 30 hours of batt because I needed camera!) and hoping that either

a) It fixes it!

b) my battery is still ****ty which would mean that it's not bricked that's causing the problem! (this would be nice to figure out what's actually draining my batt!)
[HTC Sensation] show-p1984:
First of all I hate Copy and paste posts. If you want help, you should take the time to rephrase the post to the thread you post it in.

Second: The camera is the number one batt sucker you can have in your phone. Using it will reduce your battery power even faster than a gps navigation. Therefore you will have reduced battery life once using it.

Furthermore does Bricked clock your cpu with 1536 Mhz, which is more than stock (1188Mhz). But if you underclock bricked to 1188Mhz again and undervolt for ~100mV (the exact value depends on your phone, choose the lowest that's stable for you) then you will have a phone that is a) faster than stock kernel and b) will use less battery than stock kernel.
