Phone gettin really hot using 3g And charging. - Epic 4G Q&A, Help & Troubleshooting

So I have noticed lately since eco5 after I root and install a rom don't matter if I'm CWM3 or2.5 it gets really hot when I'm using data and while its on the charger.. and if its off the charger it still gets warmer than usual maybe its just me but any ideas? When I'm not rooted and am just stock eco5 it don't get hot at all :\ I'm lost here and could this cause damage?

That's your problem, not all phones can handle scaling from 100mhz minimum, switch it to 200mhz and try it for a few hours.

Ok ill try that. Let you know ina few hours how it works ok thank you

Can't overclock

Every time I try to overclock my phone using the built in CPU settings on cm7 it reboots. It wont go past 1113 when I try 1190 it reboots I'm using tiamat kernel.

That simply means that your phone doesn't like to be clocked that high. Evo's can get very unstable when trying to clock too high, and reboots is the most common symptom. Slow the clock speed down a bit and see what happens. Also, maybe try a different kernel. The Tiamat kernel may not agree with your phone. My Evo reboots randomly on any Tiamat kernel I've ever used, including the latest one. My Evo just doesn't like that kernel, on any governor, or any clock speed I've tried. Just make sure you don't have the 'set on boot' checked until you find where your phone is stable.
It does the same using savaged Zen kernel

I'd try lowering the clock speed a bit until it's stable. What governor setting are you using? Have you tried on any different governor settings?

Performance probably isn't the best idea when you're overclocking at speeds that are known to be unstable. Try using smartass or SavagedZen if you're on SZ. For Tiamat, use interactive or ondemand.
Do you really need to overclock, or are you just doing it because you can? My phone runs smoothly undervolted. I dropped SetCPU and just use Tiamat + Viperboy's scripts. I've heard that higher speeds cause instability - freezes, crashes, reboots - but have never experienced it myself.

Very interesting plainjane
Thanks.

Pretty sure this is an issue across all of the Gingerbread leak ROMs. If I missed one that actually does go into deep sleep, please correct me

Reflashed the ROM and it looks like its working again....interesting....

Good to know..wait, isn't SetCPU discouraged on that ROM?

yeah you shoud let the system handle cpu control. I found setcpu to make performance slower..
@OP.. newer build is out fyi at acsyndicate

My phone sleeps like a baby for 89% on Bonsai v5.0.
This issue is usually something trying to sync and the modems being lousy on GB so far. Turn all syncs to manual, FB, Gtalk, emails, Twitter, all...and see if that let's it sleep. Also go into running services and see what apps are in memory. Stop ones that are not system and see if that does it.
Mine sleeps good on marcusiants rc10 rom... with ee03 modem, but wouldn't go into deep sleep with ec05 modem.

The DK28 modem is also known for this on GB. Also removing brightness.apk or lcdtest.apk can also cause this. And I have seen it right after instlling GB KB from the market, that right a KB ould keep it from going into deep sleep. Once we can tweak the kernels this will all be a thing of the past even if it isnt fixed in the final release.

[Q] How to under volt

How do I undervolt my GS2? Do I use SetCPU?
I'm currently using Gideons script. Works awesome. Look it up in the development section.
Sent from my Galaxy S2 using XDA App
Do NOT use SetCPU. It keeps the 2nd core constantly on which equals terrible battery. Use FauxClock or Gideons script. I recommend -75 mV
Thanks for the help
Is that true about SetCPU? Or is it an old wives tale......? You decide.

I'm using set CPU with no issues and I get great battery life. Less then 1% hour drain with screen off.

[Q] Restore Voltage

I screwed up and changed the voltages on my phone and battery life took a nose dive. I know I should of recorded the original settings but I didn't. Could some one please list what the original settings where and maybe some recommendations.

Disable what ever app that your using for voltage control and then reflash the kernel or rom and your stock voltage table will be restored'

Thanks tried that but the numbers don't seem correct
Sent from my SGH-T989 using xda app-developers app
Lol.. as long as you have nothing set to set voltage PR frequency at boot and you reflashed your kernel them it is right. Its not one of those maybe situations..

Proper overclocking/undervolting.

What are proper figures for doing this?
Im sure this is a noob question but I messed with stweaks a bit and my phone has rebooted randomly twice since. Could this be why?
Problem just started and I've been running this problem free jellythunder!

I'm overclocked to 1.8 and undervolted all by -100. I've had it set on boot complete for about a month now and have never had any issues. I'm not saying you won't either but this is what's worked for me.

I envy you. When I set -100 all phone gets stuck and reboots most of the time. when I set -75 still the same. Dirves me crazy.
