Wrong forum?

And no the kernel has to support UV.

Check your device forum for kernels that support it
[HTC Desire S] Nazri786:
as far as i know u need custom kernel that support undervolt....stock kernel cannot...
[HTC Desire S] Saipro:
I've always used -75 with no obvious side-effect. I have randomly tried -100 for kicks with no adverse sequelae. No noticeable improvement either. At -125, screen glitches & transient freezes/prolonged lags. Once experienced a lockup requiring battery pull. Hastily reverted to -75.

But knowing physics as I do, both current & voltage are required for powering our highly esteemed devices. If you compromise on voltage, you're likely to require more current. In my experience (and most real world applications), current drives up the heat gauge faster than voltage. And warm batteries discharge faster. Not to mention invariably drawing the same power, whether undervolted or not.

.....but we have device variations to consider, even in hardware thus variations in requirements (previously mentioned by ben-pyett too). Unless HTC had used a little too much voltage (as contingency) in which case, undervolting may truly serve a benefit to those having spare "juice". Like me. That I work routinely with -75 while some find -25 tedious is mute testimony to this fact.
[HTC Desire S] asgardr:
My UV values are been set to -100 with no visible side effects

running viper saga 2.2.0 sense 4.1 rom....

On endymion-sense 3.5, was able to undervolt to -175 with no visible side effects
[HTC Desire S] kodyro:
From my experience undervolting in endymion sense 3,5 was not working.
[HTC Desire S] dannyb2100:
I've used -50 for a while on FallOut. Works well. But I still can't really get over 24 hours on a single charge.

Using Juice Defender etc. But doesn't matter, there is always a spare USB port around somewhere :cyclops::good:
[HTC Desire S] Kingdomds:
Using now Viper saga 2.2.0 rom

UV to -100 And still no problems spotted :good:

Performance still the same.

seems that the battery is doing a pretty good job :D

At least better than before
[HTC Desire S] otterbvrn:
What is the main reason, uv setting different from one another phone? if we use default battery, and default usage...

even after I flashed a new rom and did change uv is always the same (-50 max)...

I think the reason is not related to whatever apps you have installed
[HTC Desire S] draken101:
I completely agree, screen is by and large the highest battery user by a long long way and the best way to save battery.

I have a sort of mental gymnastics exercise that actually saves a lot of battery if you do it correctly. Basically the screen immediately turns off when you press the top button. For this (first set your phone so it wont lock the screen for the first say 5 min).

Then for example if you receive a msg. You turn screen on, unlock and read the msg and as soon as you finished reading the msg you press the top button turning the screen off with app still open and running. Then think of your reply and what you want to say ect and turn the phone on and write, if you pause whilst writing to think of something else just hit the top button while you do so and then hit it again to resume typing.

Same applies for browsing the net, turn the screen off for ever single instant that you not actually doing something or actively reading something on your phone and avoid exiting and restarting applications when you do so. The android OS is actually excellent at multitasking and multitasking does not actually use more battery power, as some ppl might think, because in android, the processes actually become suspended (frozen) in a very efficient way when they not in use, and they also resume seamlessly. So they don't continually use battery when suspended they don't use any power at all, the screen on the other hand is a proverbial flood gate when it turns on the power drain goes up massively (probably about 100 times if I were to guess).

This saves more battery than any rom or app by far, you will be surprised how much time you tend to stand around with your phone in your hand - with its screen on - not actually doing anything at all. In a busy day, for me at least this lul/idle time, honestly adds up to about 40 minutes a day or even more, of battery-hungry, screen-on, time. The screen uses tonnes of battery, even if you have a screen dimmed to its minimum, it actually doesn't save much power to be honest. The LCDs still need the same amount of power to function (a lot) and the back-light is an LED which can only be on or off so the dimming is achieved through electrical pulsing (turning on and off faster than you can see, and thereby appearing dimmer) however the power saved by such operation is not that great cause it requires circuitry to run the pulsing and capacitors and other delay electronics that cause their own electrical drain and inefficiency minimising the gains made during off pulses.

Try it, it really works and it is also more sociable, because your eyes aren't continually glued to your screen, and honestly it makes you think more efficiently too.

So I flashed the eh06 gingerbread leak I know there is the eh17 but I wanted maddoggins lock parts port which is only for eh06 and earlier and I really wanted the sgs2 lockscreen and overscroll and cry off and the eh06 modem sucks. Getting terrible 4g speeds and GPS only connects with 60 meter accuracy. And the battery isn't Bad but worse than on eh17

So if I flash the eh17 modem will it really do anything to my battery? Any significant improvements or make it worse? Cuz I'm ganna flash it anyway just cuz of the data speeds and the GPS.

Many of you may have found that when trying to connect to Freenode from your phone you are getting a SASL Authentication Error and are getting disconnected.

In order to avoid this, you need to register with nickserv.

Here is How You Do Just That

First you will need a computer with an IRC Client of your choosing.

I use XChat, but similar ones are Ice and the popular MIRC.

Open your computer client and go ahead and connect to the freenode server.

Once you connect stay in the server command window, as this is where we will be doing our commands.

First you need to have the desired Nick you want as your current, so you are going to type /nick <your nickname> enter

As long as it is not currently in use or registered it should change.

Next, we are going to type in our registration command for nickserve. The command line will be as follows:

/nickserve REGISTER <password> <email>

(make sure register is in capitals)

Hit Enter

You should see something like the following:

An email containing nickname activation instructions has been sent to <Your email>

If you do not complete registration within one day, your nickname will expire.

<Your Nick> now registered to <your email>, with the password <your password>.

Next you will want to go to your email inbox as you should have gotten an email from freenode with the following:

In order to complete your registration, you must send the following

command on IRC:

/msg NickServ VERIFY REGISTER ,Your <Nick> <supplied code>

I just usually highlight and copy the command line.

Go back to your client and in the server window paste that line and press enter.

You should see something like:

<your nick> is now Verified

Thank you for verifying your e-mail address! You have taken steps in ensuring that your registrations are not exploited.

Voila, you are now registered.

Now, go to your phone client and options for the freenode server.

In order for it to work you must input your registered nick and password into the options for the freenode server and make sure you enable SASL authentication. You will need a client that supports SASL authentication also.

Once done, you should now have no issues connecting to freenode and joining

LAWL. That is not Carbon Fiber...
[Samsung Epic 4G Touch] SAShady:
Its too thick, and it's definitely not carbon fiber.
[Samsung Epic 4G Touch] bondosho:
My hood is carbon fiber, as is my trunk lid. Run your hands across it, and you can't feel the weave because of the coating that's on it. I haven't seen the case, but I wonder if it's like this?
[Samsung Epic 4G Touch] SAShady:
It's just plastic. And the high price comes because of the kick stand
[Samsung Epic 4G Touch] bondosho:
Ah, ok......
[Samsung Epic 4G Touch] paniro187:
I road race motorcycles and its understandable that carbon fiber on vehicles ha a coat on it because of rock chips and stuff. My race bike has plenty of carbon fiber on it but has a coat on it because of rock chips sand and tiny debris that might hit. The case though not carbon fiber is a damn good knock off.....
[Samsung Epic 4G Touch] paniro187:
Have you seen it? and touched it?
[Samsung Epic 4G Touch] AdamLeonard:

Why is this about if its real cf or not I ask ed if there is a holster to fit it. And I get whiney *****ing.....
[Samsung Epic 4G Touch] dev_man77:
You did say it was real carbon fiber, and there were other nards who knew nothing of the subject who wanted to chime in and say it was real and felt real.

We just want to let you know it is not real and nowhere near the real thing.
[Samsung Epic 4G Touch] paniro187:
Kind of like how stunting is not real riding? Go do a track day son. Kidding its takes a little skill.

Have you ever felt un molded carbon fiber? just a sheet?

Probably not that why you say its not close
[Samsung Epic 4G Touch] stupendusd:
Jesus. Two pages of crap.

Let me clarify.

The case IS NOT carbon fiber. Its hard plastic. It is not very thick and its a pretty sweet little case IMO. It maintains a very sleek profile for as thin of a phone as it is attached to and helps to hold while doing whatever.

Its a great buy IMO and I WOULD purchase again.
[Samsung Epic 4G Touch] Success100:
they just released A case/belt clip combo for $29.99. i need to check it out. i heard its a great case
[Samsung Epic 4G Touch] dev_man77:
Ha, not a stunter, just the occasional standup at the dedicated stunt lot.

I am in AET 378 (Composites class) Right now and I actually just got done doing a carbon fiber layup... The fake fiber on that case is far too large, its molded and its not even a composite.. its just plastic. My roommate has the case. Its not a bad case its just a little thick for my liking. Maybe in a couple weeks I was going to make a real carbon fiber case for my phone so it would be a little thinner. I just gotta check and see if the plastic on the phone is compatible with the epoxy resin that I will be using.
[Samsung Epic 4G Touch] ravizzle:
To answer the OP's question: no there is no holster case out yet that will fit the phone with the case on it. The case although thin still makes the phone too thick for the holster cases.

PS: not an expert or road racer, but im pretty sure its not real carbon fiber.

I have just updated from Leo's 2.6 to 2.7.1 and when it booted up I noticed I had no signal at all so I rebooted with no difference. I then booted into CWM and flashed Cognition, which had the same issue when it booted. So I restored an old CWM MIUI backup with no difference.

I have removed and reinserted the sim card and tried my wife's too with no difference.

Any suggestions or is this phone a write-off needing a hardware repair? Is it possible the flashing of a rom can kill the radio?

Also, can someone tell me if, when first booted, the wifi and bluetooth have 'unavailable' next to their address in the status screen on a reboot until first used? Mine do now but I can't recall if they did before. However, as soon as they're used the wifi mac address appears for example.

The backup will bring you back to the state you where at at the time of the backup. If that was stock other than the kernel then you just have to flash the stock kernel and you will be back to stock.

I was wondering if it was possible to increase the max size of an mms sent from the stock mms app in CM7. Whenever I send a picture through the stock mms app the image quality is reduced so low that the image becomes blurry. Handcent and GoSMS have options to increase the mms size.

I used to have the original incredible and I never had this issue with the stock cm7 mms app. I have been searching like crazy for a fix for this. I really prefer the stock mms app over any on the Android Market.

It seems that 1 MB or 1.2 MB would work well. That is what I am currently using in Handcent.
