i have an ipaq 114 running on marvell pxa310 processor and was wondering if i need to use xcpuscalar to underclock to increase battery life and maybe life of unit? from what i understand my processor or most xsale processors auto scales itself anyways so i don't necesarily need this software unless xcpuscalr does a better job? and if it does what are the safe frequencies to use? any opinions most helpful. thank you.
does no one have an opinion?
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.
I want to know that dual core will save the battery or its more power hungry than one core in android phone?
If both cores are working, they will both use power.
Some phones have apps available which will turn all cores off, except for 1. Then the device will use less battery.

Thanks for your reply, I will buy a dual core phone but with good battery backup.

It really depends on its architecture. If it uses a newer architecture, in general, it will consume less power and perform better than the processors with old architecture.
If you compare processor with the same architecture but one is running on one core while the other is on two core, then its obvious that the one with the dual core proc would need more power
A sample of case study that you want to look at if you want to get a better grip of it: comparison between htc one x/galaxy s3(quadcore but older architecture) vs htc one s(s4) (dual core but newer architecture)
I love my single-core phone, but the battery still doesn't last very long. I don't know if a dual core would be much worse, it also depends on the battery capacity.
recently i have bought yu yureka bu micromax
- 1.5.GHz Snapdragon 615 MSM8939 Octa Core Processor / Adreno 405 GPU @ 550 MHz
- 2 GB RAM
- 5.5 Inch HD IPS Touchscreen Display
- Dual SIM Support
- 13MP Primary Camera With LED Flash
- 5 MP Front Camera
- 4G LTE
- 2500 MAh Battery.
- Customizable Cyanogen 11 OS
the phone been heating alot.. the CPU temperature is normally 45C and it raises as we use.. when gaming it goes between 60-65 C and when i run benchmark tools or play heavy games over an hour the temperature goes above 70C the top i observed is 77C..
isnt a processor supposed to shut off at 70C? as for safety reasons till it cools down?? how much this snapdragon 615 processor can get the most? will it burn or burn other internals?? please some1 clarify my doubts! i even noticed many people are facing the same kind of issues with samsung and moto phones which runs on octa core processors.. is it a hardware related issue or a software issue???

No It will not burn any material. It is not the PC Processor, but it seems that your device heats a lot, may be it is a manufacturing defect. Try asking others with the same phone. And don't overheat your phone, dont play games for hours and hours
Hit thanks if helped

i dont play games that long.. with this device its hard to play for more than an hour.. 90% of the ppl having this device facing the same issue but most of them seems to be not caring.. some even said the snapdragon615 can withstand up to 100C is that true??
the customer care ppl said...

I can't find any temperature values on the qualcomm website. Just write a email to qualcomm for first hand iformations Phone's kernel works with thermal throttling, means depending on the actual cpu temperature the cpu clock is lowered to protect the cpu from overheating. If your hardware works as it should, you can't overheat actual processors by using I suppose. If you can find a custom kernel you probably can set own values for thermal throttling. In any case you should try a kernel tool e.g. Trickster Mod or Performance Control for setting up the cpu. If you think its getting too hot, just deactivate some cores or lower the cpu clock, your phone will still be fast enough for all your applications.
Edit: which customer care people told you about the issue?

70-80 Degrees isn't a "Worry" Moment, It's actually quite normal for a Octa core to reach that high what do you expect? Since a phone doesn't have a Fan or something like a PC, so it relies on something else which needs longer time to cooldown.
My Nexus 5 using Quad Core reaches almost the same Value (65-70).
Remove the case if you have one since a case will have your phone increase in temperature too.
thanks.. i already hve done it.. i bought a flip cover which i used only for an hour... i worry only when it exceeds 70C.. i can feel the heat near the cam.. it gewts hard even to hold it. i heard meadiatek processors doesnt heat only qualcomm processors does. is it true??
is there any other phone with the same kinda heating issue? like over 70C still survive??

They've got no email addresses only office locations https://www.qualcomm.com/company/facilities/offices
then i guess only the experianced/developers in this forums can help me.. all i wanna know that if its safe to have such high temperatures ( 65 when gaming and 75+ when running benchmarking-stress test) is it ok with this qualcomm anapdragon 615 processor... some said these processors can withstand upto 100c and 90c is the cutoff temprature unlike the old processors.. can some expert who is experianced with developing any apps for any quad/octa core processor out there please help me. i just want this much info only
I want to underclock my CPU to improve the battery life of my phone..
But my phone has big.LITTLE processor so I am afraid that if I underclock the 4 low power cores the phone would just switch to the performance cores which would defeat the whole purpose of the underclocking..
Can anyone help?
Thanks in advance.
