[Q] A different horrble battery life issue

Good day, folks! It’s me again with my mystery hardware version 003 Evo obtained back in June, 2010 and currently running EViO 2 v1.7.7. My Evo is also one that although everything works perfectly, and though there’s never been a sign of anything out of order, I get worse battery life on a 3500mAh battery than I used to get with the stock battery. Works like a champ, sleeps appropriately, etc. No one seems to have a clue. However, I may have just found something relevant.
I took it off of the charger at 5:00 AM, and between 6:00 AM and 9:00 AM I watched “Avatar” solely on the battery. Other than that it’s been asleep. No phone calls, though I did forget to turn off Bluetooth this morning when I got to my office. Anyway, I looked at the battery section recently and though the up-time and awake-time are absolutely appropriate, the usage area contains something very interesting::
Time unplugged: 5h 12m 39s (Includes 2:41:42 watching “Avatar”)
Charge left: less than 30%!
Media Server 2%
Android 2%
Phone Idle 3%
Display 5%
Bluetooth 6% (<-it amazes me that it uses more that the display)
Cell Standby 7%
And here comes the “WTF?”:
Dialer 75%!!
The Dialer details are:
CPU 22s
Data sent 367.56KB
Data received 178.84KB
Includes:
DM Command Service
Dialer
Dialer Storage
IQRD
Using the CPU for 22 seconds, sending 367.56KB and receiving 178.84KB accounted for 75% of my power usage…3-times that of everything else including the media server and the display during a 2-hour and 41-minute movie? Can that be possibly be right or am I misunderstanding something?
Over this past weekend, I RUU’d my phone back completely stock thinking it might be a software issue. Testing for a few days showed the same horrible power consumption. I re-rooted and performed a fresh install of EViO 2 v1.7.7, and of course it continues to do the same thing.
Does anyone know of some hardware issue that could be responsible for this behavior?
Any useful input welcome. Thank you for your time.

Issue identified but not yet resolved.
It appears that there is some issue with one or more radios in my phone. I don't know enough about the innerds to know if there is more than one, but whatever receives data downstream is screwed up.
Over time I've noticed that my downstream data has gotten slower and slower. Then I started missing calls periodically, and texts sent to me at 10:30 AM were showing up as arriving at 6:30 PM...weird stuff.
After un-rooting, performing a complete factory reset, and a complete data restore (from the ##3282# menu), the phone and texts seem to be more consistant, but running the SpeedTest app to a server here in NOLA produces the following results:
Ping: 20ms - 30ms
Downstream: 0 - 128Kbs (Seriously, I get "0" often, and 128Kbs is the absolute max achieved on occasion)
Upstream: 1.2Mb - 1.46Mb
After re-rooting the phone, I've tested this in the Azrael 4.0 and EViO 1.8 Sense ROMs, and in CM6.12, and the results are identical. Its very strange that it only seems to affect the downstream rate.
I guess its time to RUU, bring it to a Sprint store, pay their $35 and see if they can fix it.

Before you do that, go to this thread: http://forum.xda-developers.com/showthread.php?t=715485
Get the combo (updated wimax, pri and radio), wipe cache and dalvik and flash that. Then turn your phone back on, go to system updates and get the new PRL that Sprint released.
Lastly, install either netarchy's newest kernel or MS79723's SBC kernel (in the development section). as with the combo, wipe cache and dalvik and flash.
That's all the inner software and it'll be completely updated and modded. See if that helps out before unrooting again.
Hopefully this helps even a little bit. It sounds like your dialer never sleeps, but I have no clue what could cause that. the 22s is also just how long it had been running in that instance, it could be running 22s twice a minute all day long.

[Q] batt drain, slow down and gc_for_malloc

hi all
ive been having major difficulties controlling batt drain and 100% cpu usage after rooting and then flashing a custom firmware.
it usually...almost always..in fact- happens when i switch on wifi together with auto-sync data.
so i thought it must be one of the sync accounts, plus I'd read a bit about htc sync accounts sucking batt. So I disabled most...and there was improvement. but then it still does happen once in a while..once or twice in the middle of the night, meaning i woke to a dead phone in the morning. every time it gets so bad that I just have to reboot the phone.
when the slow down happens, i open up osmonitor, watched Android's own process log or the HTC launcher's log and i'd usually see a million of these:
gc_for_malloc freed xxxx objects / xxxx bytes in xxx ms
but am unable to troubleshoot further because it seems to be nothing meaningful.
anyone got any ideas?

I have the same problem just like yours!
I don't know how it happens?
But I founded a way to solve it temply.
when you saw the CPU load are 100% and system runs lagging.
First, launch the "set CPU" if you had installed.
Than you'll see the frq. Goes to 245 Mhz if you're set profile to "ondemand"
don't need doing anything, At least, you can see that CPU load are back to 5%~15%
As normalized. I don't know how it works? But it works everytime.
I'm using coredroid v3.2 and O/C 1.2G Hz, desire hd.
Can anyone who can tell us how it happend?

I've read that this is a common problem with many custom ROMs. If I remember correctly it had something to do with a file being constantly read. So you have to set permissions for that file which forbid reading. The trouble is that the system changes permissions again, and you have to constantly change the permissions using a sheduled script. It works but doesn't really solve the problem. The solution is to flash a custom ROM which has this fixed. Android Revolution HD 3.2 is one of them. With 3.1 I had this issue, now with 3.2 it's gone for good.

haha i don't know how you managed to get to setcpu..
mine is a near-freeze most of the time and would probably take forever to get there
but if i do get the chance i'll give it a try, thanks.

thanks, am indeed running on 3.0 so i'll give 3.2 a try.

[Q] Strange Arc S signal / battery drainage problem

I bought myself Arc S, it came loaded with .62 firmware. On my initial run, battery ran for about a day, later on for two or maybe even three days. Then I started to work in another country. As far as I remember, battery life was the same, even though the network was not (where I work now is 2G only, in my home country 3G). Then one day messed around with a Xperia S apps, did a stupid mistake and started to get force closes with launcher. I had to repair software.
Since the software reinstallation, my battery life degraded to less than a day without even touching it. Therefore I installed Battery Monitor Widget, to see, what is going on. I noticed, that battery drainage is about 70-110 ma in average, as far as I know, it should be much lower (under 30ma?). I have to say, that I tested this with .62, .42 firmware and it's all the same. When I turn phone to airplane mode, energy consumption lowers to under 5ma - which is normal i guess.
It began to bug me even more, as we bought small alarm clock with radio. I noticed, that when this alarm clock is on, despite from 2 other phones our room, my Arc S is the only phone, which makes this kind of searching-for-signal or calling speaker interference (noise coming out of speaker). My phone does that all the time, even in idle mode. This can be also heard when we have our TV on on. So, if I don't want to hear that, I have to unplug the alarm clock or put my phone into airplane, which sucks.
I asked a guy next building, if he has the same problems with Arc S, and he says that his phone can live up to 5 days with one charge (is connected to the same network provider), so I guess it is not network related?
I wonder, is there a possibility, my phone's radio is broken somehow? Or it was faulty, and firmware reinstall somehow broke it to the end? So that is draining battery all the time - looking for signal? Any way to fix this? Flashing different base bands did not help, tried that already...anybody knows a fix for this, apart from returning it to my provider - since I'm 4 months away from my country
Anybody heard for any similar problem with Arc S?
Thanks in advance! (if needed, I can also post battery usage screenshot, but I think it's not much of a help)

That seems like the issue here if I'm understanding you correctly. If you don't have 3G service where you currently are, and you did not turn off 3G, your phone will constantly try and find a 3G signal.
Airplane mode fixing the issue makes this seem even more likely. Try disabling 3G and see if it helps.

Problem is, that's what I did almost instantly when I came here, I set it to GSM only. One thing I noticed right now, when I check into About phone, under Mobile network type, my Arc S has: UNKNOWN, where my friends HTC says EDGE. Maybe here lies a problem? Why my phone can't detect network type?

Incredibly, I found the reason for my drainage and signal search. When I came into that country where I work now, my provider offered me to turn off data transfer (provider turns it off for me). Of course I did not want any unintended data transfer, so I turned it off by sending sms to service number. After I reinstalled software (that was my first reboot here), phone couldn't find network type for that reason, and was searching for it all the time. Yesterday I allowed data transfer by sms again, phone found EDGE network, can't hear any more noise on our alarm clock and battery drainage is about 4% per 8,5 hour. Excellent
I hope this helps anyone out there with drainage problems.

I think you can also turn off/disable data transfer/traffic with the Data traffic widget, if you want to avoid using data.

xperia arc s
hold up, i dont understand. so im pretty sure i have the same problem. get about 17 hours with berely using my phone on any rom/kernal/firmware. even with data turned off, betterbatterystats shows 'noor unknown signal' and 'no data conection'? i sued to able to get 3 or more days out of my phone??

I think there is an application, which might be keeping the phone alive.

dout it, still drains after a complete rom wipe

Intermittent Slow WIFI

Hey guys...
I have a problem,
once a day (or two) my wifi on my GS3 (stock, 4.1.1, videotron) becomes slow...
I try loading something (on the web)... it's slow, then I try a Speed Test.
Result is always something like : 250 or 500 or 800 KBps
Then, the solution is : desactivate wifi, wait 2-3 seconds, reconnect, and then bang 10 000 mbps. Everything is fast.
Do you have an idea why ?

Hmmm....
It could be because of the time of day. I have two wifi networks in my home (att & clearwire), and I have low bars (0 or 1) on both of them in the morning & afternoon. But all bars at night. It could also be that sometimes you need to refresh your connection, just like you have to restart your phone sometimes.

[Help] Wifi problem, slow conection

Hello I would like some help,
I'm having a problem with the wifi on my phone, I never hang the same. When I get home (this happened anywhere, my mother's house, in the company) the phone connects to the wireless network, high signal, will measure the speed of the internet gives very low, 280ms, 3 megs of speed totally unstable. with that, I turn off the wireless network of mobile and reactive again, hopefully enable and squeegee the speedtest again, everything is normal, 20ms ping, 15 megs of speed stable, everything perfect.
If the screen stays off long it happens again. I had other phones and it did not happen on the same network, such Onex and sensation
Anyone have this problem? I've tried several different roms, it seems that this problem started giving the firmware 4.1.2.
Already thanks.

testing this solution
Forget all networks registered
Just dial * # 197328640 # and the menu will open.
MENU button physical
Wifi
Disable energy saver
After some tests come back here to give the result.
thanks to ks-man for this solution...:highfive:

I would like to help, the code * # 197328640 # solves my problem, my wifi is stable after turn off energy saver. but:
One. When I restart the phone the energy saver turns on again, as has always leave disabled?
2nd. Anyone who has ever used it, thought it fell much battery performance?:silly:
