Android system & phone calls - gingerbread - EVO 4G Q&A, Help & Troubleshooting

How many people out there see their android system shoot up after making/receiving a phone call? For those who don't, can you explain what rom/kernel/hardware you're running please? Really frustrated here with not being able to make a call without losing 10% or more of my battery here.

Update: running SZ 2.0.0, tiamat 3.3.7, tiamat 3.3.5, and sz 0.2.1 all cause me to have android system skyrocket with a phone call.
Anyone?

Personally use Tiamat 3.3.7, on CM7, 100mv undervolted, and I don't get the skyrocketed android system.

Thanks for the reply! Can you tell me what radios/pri/prl you're running too? It's the only thing I haven't changed. Also did you change any settings regarding your phone calls? Basically, anything changed from stock when you flashed CM7 from a complete wipe.

Radio: 2.11.00.04.08, also no sky rocketing on 2.11.00.11.19
PRI & NV: 1.77
PRL: 60677
And for the phone, not much changed, except I don't let it vibrate on call or anything like that. Using stock dialer, no third party apps.

Thanks added I'm gonna try out the older PRI/NV as well as update my PRL to 60677, I'm on 60675 right now. I have no idea what PRI I'm on since there's no way to check in Salvage-Mod, and I gotta flash to some sense-based rom to mess with the PRL... I'll be back with the results in a few hours when I test things properly.

No need for the thanks, but always appreciated. You can go here for PRI, and you can flash the one you want, along with the radio. http://forum.xda-developers.com/showthread.php?t=715485

Well. Updated to PRI/NV 1.77, on PRL 60677, and radio 2.15.00.11.19, and I still have the android system usage after a phone call. Running salvagemod 1.2.1 and tiamat 3.3.7 at the moment.
Android system wasn't even on the chart, then one phone call test (15 seconds long) and android system is at 9%. Ugh. A normal 10 or 15 minute phone call makes it rocket to over 50%, sometimes as high as 80+. Man I want this issue to be solved, can't wait for the official HTC gingerbread so that hella new roms will start dropping and the problems can start going away.

any notice 100% awake time with 3.70.651.1?

i flashed the stock rooted RUU and i get 100% awake time... anyone else? i haven't tried any other 3.70.651.1 roms..
I did. But I wiped and flashed again. No problems since.
Sent from my iPhone with the bigger Gee Bees.
hmm i wiped and reflashed about 5 times, still 100% awake.. weird
No problem here phone is sleeping like it should. Using SteelRom rev I at the moment.
Awake meaning the screen never turns off?
Spoken from my Evo using Ultra Keyboard and XDA App
Try downloading the ROM again. You may have a bad download. Also, did you use Titanium Backup to install everything?
Sent from my iPhone with the bigger Gee Bees.
try uninstalling apps that you recently downloaded. I had the same problem on a different rom, turns out it was something called sensorly map keeping my phone up.
its a fresh flash... no apps installed. i also tried steelrom, same behavior.... if i flash 3.30.x.x no,100% awake issues. any ideas?
MarkGBE, WHAT particular item is keeping your phone in awake mode. Use some tool, like spare parts, and see what exactly is keeping it awake.
Report this info back and folks will be able to help you more.

not sure. looking in spare parts... i dont see anything with a ton of usage,.,.,.
In spare parts, Battery History, Partial Wake usage, select Since Last unplugged.
If you're getting 100% wake time, whatever's holding it open will show there.
Leave it unplugged, turn the screen off and let it sit for awhile to gather up some statistics.
currently on the top of that list is 'Media' with 2m 47 sec. second is android system. 1min 56sec..
yeah this makes no sense... nothing appears to be keeping it awake...
Just wanted to confirm that I have this problem using both most recent SprintLovers and Fresh. Even restoring from nandroid backup seems to keep it open. Fresh install, no apps. Driving me nuts.
Attempting to flash burnt droid now. Will report results.
EDIT: nada.
Using latest radios, etc. from this thread: http://forum.xda-developers.com/showthread.php?t=715485
Also using burnt droid's kernel with less aggressive undervolting.
ever since...
ever since I flashed the latest radios my phone has not went to sleep. software version 3.30 and it also seems like my battery life has taken a dive for the worst. Any ideas?

You're close. It's actually pri 1.90 that's keeping the phone awake. Just revert back to 1.77 and it should sleep again.
Edit: pri 1.90 was the cause of my 100% wake time. I reverted to 1.77 to fix it but now I am going to test the latest radios versus the radios we upgraded from and also a combination of flashing new and previous radios together.

I've also read that 1.90 PRI, coupled with 3.70 ROM causes no problems. It seems one must use 3.70-based ROM to run 1.90 PRI.
What ROM base are you using?
Edit: If you are in fact using 3.70, then I wonder if 3.70 and 1.90 need to come up at the same time? That is, if you flashed them out of sync, maybe you need to wipe and re-flash?
Well, most of the romdev's all say not to do the new radios and pri if you're not on the new 3.70.x rom and not to mix and match kernels with it either.
I personally built the rom I am using with the 3.70 base. I also updated all the radios. When I reverted the pri thats when my wake issue dropped. But its fine. I will still test and then just keep whatever works for my rom.

[Q] cpu load stuck at 100%

So I just flashed the new radio, wimax, pri, ect.... and after it freezing my phone I switched over to netarchys kernels and got my phone to boot with them on. Now I'm noticing my phone CPU is always at near 100 percent at all times and the speed is ways cranked all the way up unless I switch to powersave in set CPU wich then seems to almost halt my phone entirely. Anyine else having theses problems with netarchys kernels or the radio update ect.... or is this just me? Anti3 have any ideas how to did this without going back to the old radio update?
Sounds like you updated your pri but your still using a 3.30 based rom.
You will need to update to a 3.70 based rom

[Q] Android system running at 91% and killing battery! Myns RLS 5.

I was recently running MIUI 12/24 with the whole updated radio/prl combo pack and having absolutely no problems at all and battery life was great.
I then switched to Myns RLS 5 yesterday and my battery life has been terrible. I have tried both the stock kernel that was included in the kernel and the Netarchy 4.3 kernel and both are giving me about 90% android system usage for the battery even while the phone is sleeping. I have hardly any apps installed at all aside from the ones that were already on the Rom.
Why is my system usage so high and what can I do to fix it?
Thank you.

Hmm, this happens after a clean install before even adding ANY apps at all? Do you have facebook installed? Or are you signed in to facebook for HTC sense? I've read a couple posts showing that the fb for htc sense was holding a wake lock if it was set to sync live feed (change that from settings>accounts and sync>facebook for htc sense). If you use the actual facebook app, the chat feature will keep the phone awake unless you are in the chat part, and hit menu>go offline. It;s a place to start, if you do indeed have facebook. If you don't use facebook at all, can you use system panel to kill all tasks and see if you still have a wake lock after that? If I remember right from Myn's thread, did you say that you already tried changing your PRI back to 1.77? the 1.90 was giving me a wake lock for some reason, it was strange. If you didn't try that, even though the 1.90 was working fine for you on MIUI, I would still try rolling it back to 1.77 just to see if it makes a difference. What other apps do you have installed other than what the ROM came with? Any at all??

I haven't tried reverting back to 1.77 because I was running 1.90 fine with no problems at all on Calkulins EVIO 2 Rom. This all happened when I flashed RLS 5. I do have facebook for android installed along with facebook for htc sense. I also have chomp, system panel, weatherbug elite, and watchdog lite. I have no new apps installed that are different from anything else that I have ever had installed so I don't think that it is an app that is causing the problem for me.

Hmm, I'm not sure then. I would still try downloading system panel, and killing all of your running apps. (the ones that need to restart will). After that, see if you are still getting your wakelock. Then restart the apps one at a time, and see if any of them are causing it. (apps can go rogue, I've had it happen. Deleted the app, reinstalled, and it was behaiving normally) So just to rule some more stuff out (process of troubleshooting), I would try that. At least you'll have a little better idea of which direction to go in. You can rule out a rogue app, or determine if that is indeed the issue. Things happen sometimes man.
EDIT: I've heard of many times of weatherbug causing a wakelock. People had to delete it and reinstall, and it was fine ( i dont get it, but it worked). So maybe try freezing it with titanium backup or os monitor, just for some testing. See if it changes anything. You'll figure it out.

I dont think the PRI is the cause, I am now running 1.90 and havent noticed a difference in battery life. As for your awake time, flash Calk combo radio zip. youre probably not running the latest RAD.11.19. HTC 15 kernel wont work properly without it.

[Q] Rom Manager and set cpu help.

So I rooted my phone a couple months back. I started messing with the set cpu app and can not get it to give me decent battery life. Example. I am at 79% available battery left. It is saying that estimated time it will run out is in 3 hrs and 51 minutes. The best I ever had it was at around 10 hours on a fresh full charge.
I am running:
Android 2.2
Baseband 2.15.00.11.19
kernel version [email protected] #7
Build number: myn's warm twopointtwo (RLS 5)
software number 3.70.651.1
Browser Version Webkit 3.1
PRI Version 1.90_003
PRL Version 60676
I have no idea if that info helped, but just in case. Now for my other question in regards to rom manager. I bought the premium version. I tried downloading 3 different cyanogenmod's through the rom downloader in Rom Manger. All three attempts failed for some reason. Sometimes it would say Bad Zip File. Tried A different one. Next failed download said operation timed out. I tried the stable releases and the candidates. Every single one of them took absolutely forever to download.
Any suggestions? I have been on the computer all day researching forum after forum. So please do not tell me to keep searching, I've done all I can. Could the setcpu settings be affecting my downloading?
Thanks in advance, all help is appreciated.
Well I tried downloading cyanogen again. This time I turned on the 4g and it finished downloading in just a few minutes.
Now back to setcpu lol. I want some amazing battery life guys. Help me out
Try switching kernels. I was using nets 4.2.1 more have smartass kernel. And would get maybe 18 hours of battery life. I've heard battery life has everything to do with kernels.
All I do with set CPU is make a profile for 245/245 when screen off. I really didn't see much difference underclocking for battery life
Good luck
Evo - Myn 2.2 RLS 3 - Clockwork - HBoot .76

I actually have seen a difference by underclocking. I pretty much just put it at the minimum I need for my phone to not lag. I don't run any heavy apps or games, but I use ADW Ex & a ton of widgets. I'm usually good at 499-768 for the max. If I'm doing something more taxing, I'll push it up a little but I never need to overclock.
I'm using the latest kernel from savagedzen. It's an sbc kernel, and I know the risks, but I get better battery life than I've ever experienced. I use the savagedzen governor as well for the best battery & performance.
It really depends on your usage, trial & error was what got me to where I am now.
I would use a screen off profile if you aren't already, this will do more good than just undervolting.
If your battery life is horrendous, check Spare Parts for "partial wake usage". If there's anything in there that's really high, I would uninstall it or change it's settings. This is keeping your phone from sleeping properly.
I just bought 3 1500mah batteries & an external charger on eBay for ~$10. This way I'll have 3x the battery life & I can save the other for emergencies. I'd suggest doing something similar. There are extended batteries, but it makes your phone fatter, so I skipped on that.

I'd have to agree with what she says. Though, if you are using a HAVS kernel, using setcpu counter balances the two, so no need to use it. You can also change the governor of your rom to smartass, which is almost like a setcpu+. As for screen off, I would use 128/128 for minimum power draw. On CM7, I use smartass governor or conservative, with 128/614 as my max, no lag whatsoever. If I play a rom, I may up it to ~700 and still great performance. I bought an extended battery as a test and gives longer battery life, but does make it thicker, and slightly heavier, and I can still get a little over a day on the stock battery. Also remember to turn off your radios when not in use.

CM7 had a few too many hickups for my patience, such as no 3g or wifi was working, and a few other things. so i am going to try and use one that is more stable. Now one thing i noticed throught out the day was that my sd card had little space left on it. I want to empty things out I do not need or use. How can I know what it is okay to delete and what I shouldnt delete?
I love the functionalities of the cyanogens. Are you saying that the cyanogen had its own built in governor? Also do you use rom manager for your kernels and roms?

Well everything is working in CM7...wifi, 3G, and 4G. I'm on the latest nightly with no issues. And well what types of files do you have? Check you backups, in the clockwork folder, also the get folder also in there, if you have premium and download roms, as they take up space. Also app folders for things you don't use anymore. And yes, i have a built in governor, currently on smartass setting. And I flip between amon_ra and clockwork, currently on clockwork; I have no preference. And I occasionally use I use it to download a rom, but normally transfer it from the computer to the phone.

You may have been in a low signal area, or it had trouble connecting. May have been a bad flash. And you can download CM7 in rom manager, but you can only get RC1 and RC2, you can download the nightlies only if you have the premium rom manager. I most download and transfer from my lappy.

That's awkward, but you can try that. As for the back up of the rom, just go into rom manager, and click backup rom, it'll back it up. Then if thigns go wrong/you don't like the current rom, you can boot into recovery and then flash it as it was then. I'm on 19, no problems whatsoever.

Yea, mount your sdcard to the comp by usb, then enable disk mount, open the sdcard folder, copy what you want. Then you can do a factory reset/format sdcard, and start over that way.

okay thats what i was going to try. i was thinking that the only things I need to leave on the sd card is the clockwork folders? Does that sound right? For some reason every single cyanogenmod I have downloaded and installed will not connect my 3g. Every other rom I flash works just fine.

[Q] battery life horrendous! help please!

ok so this is my situation, i have flashed nearly 3 roms in the span of 2 days, and my battery life is horrible on all 3, Myn, mik 4.5 and 4.4, i updated all my radios, and wiped everything using format_all zip. . . and nada cache and dalvik too. . . i check battery and Android system takes over 70 percent of battery! do u guys think it can be a rouge app? if so is there an app that monitor all apps my to check which ones use the most cpu?? thanks!

thanks for the quick reply?
should i downgrade only PRI or NV too?
you should try process manager, it tells you which apps are running on real time and tells you how much cpu is being use, that should help you pinpoint if its an app. also ive noticed that every phone takes roms differently, because my wives phone had some isues that mine didnt in some roms and mine had some that hers didnt in some roms. i have noticed that that my battery life increased alot with setcpu and underclocking my evo to 245 when screen is off, also turn in settings moble network setting data always on, that will allow your data connection to stop when you are not using it for a while and come back on when you need it. also try turning mobile networks completely off and do a normal reboot, then turn them back on. ive noticed that with some roms when you first start your phone it immediately conects to 4g when it starts and when you turn it off, it still keeps trying to connect in the background, but when you turn mobile networks off and the reboot and then turn mobile networks on afer it reboots the problem is gone. hope this helps you with your battery life
sorry correcting a typo in the previous post, i meant turn mobile networks always on to off

No, you do not need or have to downgrade the NV. The current baseband and PRI causes wake locks, thus, a major reason for the quick battery drainage. Downgrading the PRI should eliminate the wake lock issue and improve your batter life.
Just Me, D

Some people have said that they downgraded the PRI and didn't get the battery savings until they downgraded the NV. Just depends on your phone sometimes.
Here's a link to download different versions. Thank Calkulin for this, he is the man. http://forum.xda-developers.com/showthread.php?t=715485
I've used MikFroyo, Myn WarmTwoPointTwo, MIUI, CM6 and CM7, and by far I would say I've had the best battery life with CM7 and MIUI (CM7 just barely better.)
Try a different kernel if you want, I just Tiamat 3.3.1 for AOSP ROMs and Netarchy-toastmod 4.3.4 (both CFS HAVS no-SBC). I've had good results, stock battery lasts a day with moderate to heavy usage.
