Hi,
i have one main question :
how can you overheat a ram , a cpu , a battery in a smartphone logically ( with a software )
do you need to control the voltage to overheat the cpu, the battery, the screen and the ram?
is it possible to do that on a rooted phone via a remote software?
overvolt a cpu can make the cpu overheat?
overvolt the ram can make the ram overheat?
overvolt the battery can overheat the battery?
overvolt the screen can overheart the screen?
is it possible to control the data rate on the usb port? and overheat it?
i just need to know if its possible with a software?
thx

More voltage equals more heat.
Yes, rooted devices can overvolt(overclock) CPU, GPU, etc..
Try using the Kernel Auditor app.
Is there a way to do this remotely? Only if its your device. To do this to someone else's device remotely requires additional software and the owner of the device has to also have the additional software installed on their device plus they have to specifically give you permission to connect to their device through the software.
You can't "hack" someone remotely to do this.

Hi,
it is possible via kind of stealth rooted management monitoring software , carrieiq......
you should read about gammagroup, hackingteam, pegasus, nso group, skygofree
you can jailbreak or rooted a phone silently via plugin a usb cable, its not because its not available online for regular customers that it is not possible
you can hack over the air almost everything via the radiochip or accelerometer, speakers, micro (siri, alexa, cortana........) its just a way in and a way out
but you have to be at close range, even the nfc is dangerous, you can expand the transmission range........ it is not truly hacking just spying but with a detructive purpose like a SHUT UP or GET OUT
i 'm facing this kind of persistant kind of bootkit or firmware rootkit inside my devices not only in my smartphone........
if they don't use my baseband against me ( battery draining, silent ping......4G 3G downgrading.......cut off my data connection.....)they put a tiny kind of tranceiver inside embedded in the logicboard, inject data stream inside the cpu or the memory.... modificate everything in memory , in fact it is like your badbios
off course they control my phone 24/24 hours, if i speak they destroy my devices
they monitoring me and harass me for DECADES ...
its spying and harassment "illegaly of course" but you do whatever you want when you are in your country
so i will have to buy all my stuff out of my country
but i'm a kind of blacklisted guy so i will face the same kind of harassment overseas
^^ if you want to destroy someone, its not difficult when you are innocent you just build lies , bad reputations.....

The question is often, how to overclock and there is a bunch of thread on that, but what about "downclocking" ?
I was thinking of that to extend my battery life when using low CPU consumption programs. Is there a stable program that can be recommended (my processor is a Samsung SC32442 400MHz Processor) ?
Thank for your support !
I would also be interested in something like this. Also a program that could suspend different parts of the phone would be nice. I would really like a program that could shutdown the display when playing mp3s on the pda.
Forgive me if these questions are elementary or if they don't even make a lot of sense. I'm not claiming to be a hardware genius by any means, in fact I'm quite the opposite.
My first question is whether or not it is possible on an android device to RAID the internal partitions in any formtat? I think this would require two flash sources and my question then is whether or not, if the hardware was theoretically able to support it, the operating system would support a situation attempting to boost read/write speeds utilizing a RAID setup. Maybe there isn't even a benefit to doing this with flash? If there is, what would be some of the benefits, and conversely, drawbacks of this?
The next question I have is what the capabilities of bluetooth 3.0 are. Specifically, can BT 3.0 be used for 1080 video playback? And can BT be used in something like fastboot?
Thanks in advanced to anyone willing to field these.

To achieve higher performance we would probably go for a RAID0, the obvious drawback here is that if one of the memories fails, all data is lost.
With the hardware its not that much of a problem if it supports raid, but rather if the systembus has the bandwidth for it to be worth it.
There is 'MDADM' a software raid solution for linux.
You could try to compile an android kernel with the mdadm module loaded...
In the end though... why all the effort...
Why do you need this .
Hi,
Thanks for the response. Well what I'm getting at here is trying to think of ways to enhance a phone's performance without this arms race of faster and faster processors that ultimately consume more battery life with each successive increase in performance. Much like the SSD and SATA did for desktops, we should maybe focus on other areas in which phones get bottlenecked and let the chip engineers worry about smaller and more efficient instead of faster and faster.
There's a serious problem with smartphones and that problem is battery life. I'll be willing to bet that the overwhelmingly vast majority of consumers are willing to give up things that (albeit may seem necessary to us devs for our fun) are simply not very much used by the every-day consumer that doesn't even know the difference between Gingerbread and Honeycomb. I think HDMI is one of them and if BT3.0 can transfer 1080p then what's the point of having so many features in a phone that can be done by one and wasting valuable space for that additional few hundred mAh of battery power?
Most of the phones that are coming out right now do not need to get smaller, I think the market has a sweet spot for thickness and size of devices and these phones are in there--but the batteries are not. I don't know about you but just about everyone I know complains about battery life and I would kill for a phone that can go 2 or 3 days without a charge.
That is why I have advanced task killer as well as a sbc kernel. I enjoy all day fun with all the bells and whistles too.

Stay away from task killers. They actually do more harm than good.
Check out an app on the market called tasker. Helps you to manage your battery more efficiently.
Stay away from task killers.
Bluetooth 3.0 allows a faster streaming of data when used to network information between Bluetooth devices.
Essencially yes. You can stream 1080p videos using it... but... the device your streaming it to/from needs to support the standard as well.
Ex. You decide to teather your tablet to your 4G phone via Bluetooth to watch 1080p YouTube videos.
Your phone supports 3.0 and you tablet is also 3.0. Streaming will be nice and fast.
But if one of the devices is a standard prior to 3.0, you 3.0 device will transmit at the fastest capable speed of the lesser network
I hope this helps.
And by the way,..
Stay away from task killers.

I sorta want an answer from anyone who knows about Android architecture... elixir is an app that reports different specs in real time. I.e: cpu temp or ram usage. (For those that didn't know). I showed a friend and he says this stuff is kinda fishy since it can only focus on one core at a time, is it giving false info on dual core phones? How does it obtain info on the CPU temp too? I don't know what to do since I like using it and he just told me its a piece of crap...
Well without seeing the apps code, you can't really tell how the app works.
I also don't understand what your friend means by "it can only focus on one core at a time". What does that have to do with reading out ram usage or temperatures?
The cpu temperature is somtimes not the real cpu temp, but the battery temp. Not all devices have temperature sensors on/in the cpu.
haha the elixir is samsung galaxy SII the battery life is very very good thanks samsung ^^
Dual core phones have two threads of data that they churn out and apparently its impossible for the app to read both simultaneously.

Cpu Usage and Ram is probably read from files like '/proc/stat'.
I'm still confused about what your problem is with dual core devices.
Hello, is there a way to reduce the heat due to high CPU frequency? In fact, when I play games such as Real Racing 3, in order to maximize my phone's potential as it has quad core, I usually set my CPU to maximum frequency (1.8GHz). However, l discover that the CPU drops back to 1GHz or lower, after about 10 minutes of gaming. In the beginning, I thought that it was a bug, but consulting someone in this forum, I discovered that the drop is part of the CPU protection feature. I appreciate this kind of safety feature but it will be boring that you can only enjoy a short 10 minutes of gaming before the phone heats up like a kettle. So, here is the question, is there a way in order to reduce the heat due to high CPU frequency? Will undervolting (UV) be recommended? Thanks.
Heat is generated as a byproduct of electical risistance... You'll have to exuse the bad spelling till I fix it...
1. under volting will reduse the electrons that are alowed to flow, thus reduceing the heat genorated, and it will also reduse your devices' performance.
2. A heat sync will reduce heat if the flat part is placed where the processor is. I ripped one out of an old copmuter and set my phone on it when modum tethering when playing online games and it works well. But not so comphotable when actualy using the device as the metal flanges coming off the other side of the heatsink are pokey.
3. A cpu govener change is the most likely solution to your problem of auto throteling and ramping of your devices' cpu friquancy. There are guides and info kicking around that using a google search like this:
cpu govener site:www.xda-developers.com
Will result in helpful reading matierial. I'd sugest looking at a program like rom tool box that will alow you to set up profiles that triger diferent cpu speeds and govenars bassed off of what your device is doing; such as when the screen is on, max frequancy=max, govenar=smartassV2 and; when the screen is off, max frequancy=50% of max, govenar=conservitive.
4. When all else is not good enough and you've gathered some info on how your device handles different govenars; then build your own. From what I've been reading its not so diffacult to tell your device exsactly how to behave in every way.
Hope some of it helps. And if you need some help with finding spisific sorces of info that I've hinted at, say something and I'll add some links when I spell corect this.

I'm looking for an Android Stick for mobile, battery driven operation.
Can this be done?
Graphics hardware is not strictly needed - so could be disabled to save energy.
You can use any TV-Stick and power it with a portable power bank like this one:
http://www.amazon.com/6000mAh-Portable-Rapid-Recharge-External-adapters/dp/B00EF1OGOG/ref=sr_1_4?ie=UTF8&qid=1387725779&sr=8-4&keywords=powerbank+5v
There are also ones that run with AA batteries if you prefer that. The only thing you have to keep in mind is that the output curren has to be appropriate. For single-core sticks, 1A will do, but for dual or quad core you should look for a power bank which outputs at least 2A.
But i don't really get why someone would need a battery powered tv stick. You need power for your TV, so why can't you use that for the Stick also?
I don't need a screen for this. I want to disable the graphics chip (or even rip it out). How much power do you think does the typical GPU consume, compared to the CPU? (Or all everything else?)
If such an Android stick is getting hot, is it rather the CPU or the GPU?
These devices (and i think all other devices that run Android) are all based on SoCs (System on a chip). This means that CPU and GPU is the same chip, so sorry, no ripping out of the GPU .
Power consumption depends on the task that is performed by the chip, and so does the the heat generation.
There should be a difference in power consumption between a) not performing any graphics related tasks and b) putting the GPU, the video memory and the HDMI port all into suspend mode - similar to sending a smartphone into suspend mode, while keeping the CPU running.
How much power saving b) will amount to, I don't know. Will it be closer to 5%? Or closer to 30%?
The portable power bank you linked to above is a little big for my use case. I would prefer to use a smartphone battery to power, say, a single core device. Do you think this would be impossible?
Android HDMI sticks are USB powered, so they need 5V. If you have some knowledge about electonics you can use any battery you want. You just have to build a circuit that converts the voltage of the battery (smartphone batteries have 3.7V) to 5V.
The power consumption is very hard to estimate. I would say a single core with idling GPU will consume about 0.3 - 0.5 Ampere depending on the CPU load.
But if you want a small android device powered with a smartphone battery, why don't you use a smartphone? What's the advantage of a hdmi stick?

I do not need a screen. So this is an advantage. I hope to find a battery that fits hush with the board. I like to carry the device around in a pocket. In addition to suspending the graphic hardware, I will try to throttle down the CPU, in order to make it consume less energy.
Do you think I will be able to get the power consumption down to levels of an average smartphone? Or are there fundamental differences that make this impossible? In which case I would indeed need to look for a smartphone SOC based solution.
The SoCs in these sticks are also used in cheap smartphones, so the power consumption will be about the same. If you want to underclock you CPU you should look for a device that has custom kernels, because most stock kernels do not allow over- or underclocking.

May I ask for HW suggestions, pls? ATM, I have no clear idea what would be the best hardware/vendor relative to my requirements.
Availability of custom kernels would be good. Availability of usable kernel sources would be even better. A big plus would be availability of 4.3.x - due to improvements in the Bluetooth stack, among other things. Any chance to run pure AOSP on any of these stick devices?
Thx.
I am quite sure that there is no device that meets all your requirements.
I know that there are custom kernels and even a (bad) cyanogen mod build for the mk808, but it is a dual-core, not a single core as you wanted.
And Android 4.3 is not available for any of these sticks. Maybe it will come as an update for the current generation of quad core sticks, or maybe not until the next generation (mid 2014) arrives.
