[Hero CDMA Q&A, Help & Troubleshooting] hostileenviroment:
apologies. your first post seemed a little condesending.

i actually get better signal w dd. 74dbms. a little ironic huh lol

i updated my recovery, wiped everything twice, and reflashed. installed NOTHING and its till draining. im going in for a redownload.

i think their are plenty of ppl with the battery issue...ppl who dont care tho, or dont know, or just havent posted

thanls for your help devin, i appreciate it. so whats the next step?
[Hero CDMA Q&A, Help & Troubleshooting] DirtyShroomz:
My battery issue is documented, I barely get 8 or 9 hours
[Hero CDMA Q&A, Help & Troubleshooting] A_Guy71:
Unplugged at 10AM this morning, it's 2:10PM now and I'm at 46%. Heavy usage, on the internet for probably an hour and a half atleast. I thought this was normal battery usage because it's all I've ever gotten. Doesn't bother me because I carry around an extra battery for a total of 16 hours battery life, and I have a third battery if I intend to go for a while without a charger :D

EDIT: Signal is -88 and is usually always around that point.
[Hero CDMA Q&A, Help & Troubleshooting] brokentoaster24:
i was using the latest radio from flipz (2.42.blahblah) and my signal was hovering around -95 dbm, just flashed the old stock radio and it's up to -75ish dbm
[Hero CDMA Q&A, Help & Troubleshooting] DirtyShroomz:
So what's better -95 or lower (example -75)
[Hero CDMA Q&A, Help & Troubleshooting] comintern:
Higher (closer to 0) is better, so -75dBM is better than -95dBM. -70dBM or better should be full bars. -100dBM should be the worst signal that displays 1 bar (if it displayed right). One thing you might try is pulling the radio interface library from DamageControl and push it out to /system/lib/libhtc_ril.so. I think Darch uses an older version.

my phone is draining like water between my fingers. if i post a logcat, will that help?
[Hero CDMA Q&A, Help & Troubleshooting] lineman78:
By this do you mean that the always on mobile setting is disabled by default. That setting alone has doubled my battery life on other phones. Also, for those with lower signal, consider disabling the "Use wireless networks" setting under location. With low signal it can cause more battery usage than GPS. Devs that think they are helping by trying to use wireless signals for location are actually hurting. A big one that comes to mind is Locale. I have written the dev once and about to write again. They turn on wireless all the time to try and use it for location and they don't turn it off after. Even when my current conditions in locale specifically say to turn wifi off.
[Hero CDMA Q&A, Help & Troubleshooting] DevinXtreme:
Do you have GPS always turned on? I only turn it on when I'm using it.

Have you removed apps that you don't use? I've created a .bat that automatically removes all the stuff I don't use (Livewallpapers.apk, for example), pushes my current ringtones to system storage (it's faster, more battery efficient) and then reboots the phone.

Do you have autobrightness on? I have my brightness stay at a low-ish setting (still visible mostly everywhere, though) because I noticed the light sensor was being a little wacky.

What baseband and PRL do you have?

A logcat may be useful to people who know more about the jargon that those spit out. I've solved a couple of my own problems by looking through them, but I knew what I was looking for. I wouldn't know what to look for in this circumstance.

Mobile Network Always On is just default on this ROM. I've yet to find a setting for it. However, I found an app (Well, gomorrah pointed it out to me) that allows the data network to be turned off. It's called SwitchPro and it costs $.99 and it's well worth it.

I leave the network location on, but that really depends on your location. I've never had a problem with it.

The batteryfix/x/x/xes that I mentioned fixed a wakelock issue that happened in 2.6.2(?). Ever since then, the fixes were incorporated into the ROM. That doesn't mean that new problems could have arisen, but that those problems are patched. It doesn't seem to be a wakelock issue like it was in the past.

What I recommend to everyone is to follow the standard bug-reporting procedures detailed in the first post for the ROM. If there really is a bug, darch should be able to nail it.

And one last thing; can everyone with battery problems do this for me and post their results:

adb shell
top -m 5 -n 1

(If you could run it a few times over, say, 15 minutes, using the phone as you normally would, this could cause something to show up)
[Hero CDMA Q&A, Help & Troubleshooting] lineman78:
I know what my cause is... I have very poor signal at work and it spends all day just trying to squeeze out enough signal to get emails and sms. Disabling always on mobile has doubled the battery life of my phone and every other person that has said they tried it and has no side-effects that I have found. I am new to Darchdroid. Does Darch have a bug management system or a process to manage bugs/feature requests?
[Hero CDMA Q&A, Help & Troubleshooting] DevinXtreme:
I understand. I used the same feature in all the sense-based ROMs I used.

There is the bug reported, but I don't think there is a feature request system. You can post in the thread, but that's about all. Darch has already commented saying that he doesn't plan on ever including the mobile network always on toggle.
[Hero CDMA Q&A, Help & Troubleshooting] davec1234:
Any consensus on radio version?

Flipz has several to chose from.

My signal blows at home on this Rom, didn't prior.

I'm guessing that's hitting the battery as well.

So I'm curious which radio people are having the most success with.
[Hero CDMA Q&A, Help & Troubleshooting] HeroMeng:
I have crappy battery life on DarchDroid too. Under Partial Wake Usage it says Messaging partial wake usage'd two hours.
[Hero CDMA Q&A, Help & Troubleshooting] radxcoresteven:
I get a max of 10 to 11 hours with maybe 30-45 minutes of heavy usage ( internet, calling) and texting throughout the day. Currently, in my home, I have -96 dbm..I'm going to try some different radios and I will report back.
[Hero CDMA Q&A, Help & Troubleshooting] davec1234:
Cool, I'm going to do the same later this evening.
[Hero CDMA Q&A, Help & Troubleshooting] MediocreHippie:
I have serious battery issues as well. What info do I need to give to see if you guys can help me out a bit?

EDIT:

I use no AutoKillers, no OC apps, and I leave bluetooth, WiFi, and GPS off unless I'm using them. I didn't wipe before upgrade.
[Hero CDMA Q&A, Help & Troubleshooting] davec1234:
Check your signal strength, if that's good you can rule out needing a new radio.
[Hero CDMA Q&A, Help & Troubleshooting] MediocreHippie:
-89 dBm -101 where I am now. This is where I am most of the time though. Not sure if that's a good signal or not.
[Hero CDMA Q&A, Help & Troubleshooting] davec1234:
I'm at -84. It's worse than I've had in the past.

Hum im getting great battery life....( 3500 mAh battery ) lol... But I did a test yest.I used the stock battery for 12 hours...left everything off.. even data..only turned it on when i needed it.. and got like 10 hours of good solid battery life..down to 20% by night.. and thats oc'd to 768..and 480 while sleeping..

Using the newest radio from fresh.. prl 60666.. <--kinda evil dont ya think..lol

I did a total fresh install..and havent had a single issue.. so i dont understand why people have issues..but the hero seems to have hit and miss things all over the place. what works for one.. doesnt for the other..so who knows..

But im loving the new darchdroid..think ive finally found a new home for my rom needs..

Look and see what's taking up the most of your battery in the usage statistics. If it's cell standby, you have an issue with signal.

:/

Or you could check the date on those posts and the date of my post. I don't know, he was the only one complaining at the time. But kudos to you for noticing that *thumbs up*

Anyway, I feel bad for you all with bad battery life. I get excellent life out of this ROM. Best experience I've had on any ROM. I sent and received around 200 texts, made several phone calls, and did A LOT of web browsing, GPS (via Google Star Maps) and I'm still at 61% after 16 hours. I really wish I knew what I was doing differently (other than living near a tower, but I don't think that would have THAT big of an effect, especially because I traveled today.

I'm running on a clean wipe install with Googleshits. I've deleted the following .apks:

LiveWallpapers.apk
LiveWallpapersPicker.apk
Gallery3D.apk
com.amazon.mp3.apk

I use the 2D gallery, I have my notification and call ringtones moved to the system memory. I used GodSpeed recovery. Most current PRL, second most current radio, Handcent for texting. I don't use any kind of overclocking tool. I use Google Voice for Voicemail and an occasional call. I have calibrated my battery (twice, once when I ran DC), I use the BlackXeth theme (Metamorph style), I have the end call button set up to put the phone to sleep and push it often. I use ADWLauncher darch posted.

I don't really know what else to say... :/
[Hero CDMA Q&A, Help & Troubleshooting] reedsw:
Not to split hairs with you, but I did check and on the 16th there were half a dozen, including mine, not 8 hours before you made another reply in that thread... *thumbs up back atcha*

I feel horrible. The time I was using it I absolutely loved it. Was really disappointing to me half to remove the ROM because the phone wouldnt make it through the night on 100% charge and me wake up and it not be dead.

Will be running your fix suggestions and re-reading the thread for anyone else who might have come up with a possible solution this afternoon as it seems I will be light loaded at work today ;)

Edit: @ DevinXtreme: Pretty much all of the settings minus the BlackXeth and unsure of the PRL and radio are the same as what I have/done. The radio is getting me currently -75 but went from -66 on the PureHero ROM this morning (just flashed darch again after running a Titanium Backup). I use beautiful widgets, a data counter, the sd and internal memory widgets, News and Weather and thats about it.

What I did different this time was I flashed darchroid and googleshits on the same reboot. I hand picked my widgets and titanium back-up.
[Hero CDMA Q&A, Help & Troubleshooting] reedsw:
What would stand out as being the drain? What should I be looking for then the terminal spits this out?
[Hero CDMA Q&A, Help & Troubleshooting] DevinXtreme:
Weird... When I look for it, I don't see anyone but the OP... After he posted, a lot more people came out of the woodwork. I was replying to your comment late last night, was very tired... Apologies for being snippy.

Anyway, I have Beautiful widgets smaller home, BatteryLife widget, Handcent message widget, a Gmail unread count widget, Pure grid calendar and weather, SwitchPro widget (it allows you to turn data off, but I was having excellent battery before using it... But it helps a little), AudioManager widget, and Urban Dictionary widget. I use only three screens on ADW. When I'm in my basement (where I get the worse signal) I have about -75 to -80 dBm, and when I'm upstairs I get -60 to -65 dBm.

Honestly, I really wish I could help you guys. After we get a few more tests on darch's new undervolting flashable, I'm gonna try it out... I may never have to charge my phone again.

It's testing to see if anything has abnormally high idle CPU usage. No item should be above 5% (give or take a few percent), and the one that should be the highest is "Top". However, if any of the numbers were high, you'd see a lot of phone slow down.

To show an example of this, try opening an app (something heavy) and immediately run the command. That app will show up on the top of the list using a lot of CPU.
[Hero CDMA Q&A, Help & Troubleshooting] reedsw:
Ran that with Pocket Empires running and got a 7% hit... everything else was 5% max.

I am charging this thing to full, wiping battery stats and praying because this ROM is really worth the attempts to get it right, imo.

You have way more stuff going on than I ever do. I only use 3 screens myself but they are half to 3/4's empty except for the default screen.

No worries about snipyness as long as it is followed by actual attempts to assist :cool:

My -75 right now is on the 9th floor of this 27 floor building somewhere near the center. I dont expect the best of anything here =)

Thats really great news. I was sitting here thinking maybe its one of these widgets I have running (Devin killed that theory), I also thought maybe it was because I was coming from PureHero (numberous people killed that one). Tried the calibration twice now...

Current recal results. Unplugged and "sleeping" for 12m57s, down 3%

Cell standby 41%

Display 29%

Phone idle 24%

Android System 6%

Thats 6.5 hours if expounded, which would be just the amount of time I sleep and would get a dead phone in the morning. So frustrating. Going to keep poking at this thing though... have to... enjoy it to much.

[Hero CDMA Q&A, Help & Troubleshooting] Decad3nce:
You shouldn't have any duplicate system processes; whatever caused that is the root for your battery drain.

Have you tried a fresh flash(including fresh download of DD)? You should also check if your sd card is corrupt.
[Hero CDMA Q&A, Help & Troubleshooting] reedsw:
I have to agree one the cause... I am just glad I found it.

When you suggest a fresh flash... just reflash the 2.7 zip? Wipe, no wipe?

Pretty sure the sdcard is fine. If I run the a2sd zip by darktremor the apps2sd works then (know this because of the first attempt at this rom). Doesnt make any sense to me either.

Should I attempt to run the a2sd zip first and see if I still encounter. With the multiple system processes still popping back up even after I kill them it doesnt seem to effect battery issues as I was able to sleep 7 hours and wake up with 50% battery left.

Autokiller app is set to extreme now... dont know if that is really that big of an effect considering I am still finding duplicate processes.
[Hero CDMA Q&A, Help & Troubleshooting] Decad3nce:
Darch already has Apps2sd set up on his ROM, no need for Darktremor. Just go to settings>applications.

What I mean by fresh install:

Re-Download 2.6.7

Wipe EVERYTHING (including your ext)

Then flash again

Then check if you have multiple processes running

[Hero CDMA Q&A, Help & Troubleshooting] mrinehart93:
Guys, I think I've finally come to a conclusion based on various things I have read. Here goes:

You may or may not have read, but the HTC/Sprint ROMS put the network to sleep when the phone is asleep. Evidently, in AOSP ROMS, the network does not sleep when the phone is sleeping. Now, we can rule out the multiple processes etc. because above me, it is being proven that it does not show any significant effect, if at all. Based on various posts I've been reading over the last week or two, people that have bad signal (checked by the dBm in About Phone) usually have worse battery life than people with good battery life. For example, DevinXtreme said that he LIVES by a Sprint tower. He also mentioned that his battery life was EXTREMELY good. So this is a very good case in which good signal = good battery life. So in all, I think it is safe to assume that the cause of the battery life problems rests solely on the network not sleeping when the phone sleeps. When you are in an area with bad signal, the phone will constantly be using that bad signal, instead of sleeping and partially ignoring the bad signal like a HTC/Sprint ROM will. This will result in an incredible battery drain. People that have good battery life on other non-AOSP ROMS experience that because the network is put to sleep. So, I think the only solution would be to implement the network sleeping feature that is present in HTC/Sprint ROMS into DarchDroid. For the timebeing, I would suggest using an app that is able to enable/disable EvDO. By doing this, the phone will only be using 1xEv when it's sleeping, rather than EvDO which will hog the battery. Feel free to take this with a grain of salt, since this is just a stab at the problem that I've gathered from spending great amounts of time reading through peoples problems.
[Hero CDMA Q&A, Help & Troubleshooting] Decad3nce:
How can you rule out multiple processes that never should be there?

I'm fairly certain Sense/HTC ROMS don't put your "network" to sleep, sure they may have a "always on mobile data setting" but that's not even close to the same thing, where are you getting this from?

Anyone who has multiple processes running has something wrong, so whoever has those processes present, please do/list these:

1. Tell us the recovery you are using

2. Boot with no sd card in and check for multiple processes

3. Give us a logcat from boot up to the point where you think the boot is done

4. Tell us if you're using any kind of task killer

5. Check the update.zip that you're flashing for multiple apps/frameworks

There is no way that this is a problem with the ROM. It's something that the user is doing to create the scenario, and if you do/get us these things, we can help you out.
