Radio draining battery - EVO 4G Q&A, Help & Troubleshooting

My radio has been draining my battery at a record pace recently. At 100% battery, I leave my phone on at night. Around 9 in ther morning, there is about 15% left. What could be the problem? I am running kings elite and have had great battery up until about a week ago.

What leads you to believe its your radio that is causing it? It could be a run a way app, locking your CPU at 100%. Have you checked your up time vs awake time to see if you have a wake lock? If you do, the times will be the same, or very.close to the same. What radio and pri are you currently using? Sometimes the 1.90 pri will cause massive battery drain. Changing to pri 1.77 usually solves that issue.

I've turned my radio off at night and the battery only drops maybe 10% at most.
Edit
But I will try down grading my radio.

That doesn't necessarily mean its your radio for sure. It could be that an app is using the radio, sending and receiving data. Also, using spare parts is good for tracking down a runaway app

You're welcome. Also, sometimes if I've I'm not too attatched to the setup I'm using, and I happen to have some battery issues...I'll just do a complete wipe, and re flash the rom. Start fresh, and download all my apps again from the market, and install them one at a time. Then I monitor after each app I install, before installing another. Kind of tedious, but sometimes if you can't figure out what's causing a massive battery drain, that's the best way. You know you have a clean start.

Even if you were attached, you can still backup your launcher settings, and apps in titanium, then you can figure it out, and then go back.

You speak the truth! I just like doing things the long way, haha. I find it refreshing to start clean and fresh, without restoring anything I have saved. Just a total clean start. I guess I'm crazy, lol.

Well I think I may have found the culprit. Seems I was signed into latitude. Until I signed out my up time and awake time were identical. Now things are looking like they are getting back to normal.

There is a thread by Calkulin, that has all radios, hboot, pri, wimax versions. Its in the dev section. Download the 1.77pri, and flash in recovery. All of the ones linked in calkulins thread are flashable in recovery. I would link you to it, or attach a copy for you, but I'm on xda app. And no, you don't need to be on a sense rom to flash the pri. Maybe you were thinking of the prl, which you do need to be in a sense rom to update.

Random 100% cpu usage. A.k.a. AGGRAVATING LAG!

About 3 times a day, my evo will start to lag horribly. I check system pannel and it says the cpu usage is 100%. Then i look at the processes and theres like 3 apps running and then the normal system processes. Anyone know why?
Sent from my PC36100 using XDA App
Which apps are running and maxing your CPU usage? All 3 or 1 of 3 could be the culprit? Apps like Watchdog can tell you what app is blowing up and you can take it from there. I've had a few get out of hand and killing once or uninstalling / reinstalling has corrected it. Clearing data / cache for the app might help. Gotta figure out which ones are maxing it first.
blah blah effin blah
Usually its my normal stuff like handcent, lookout, ane maybe music. Its like one minute its fine and the next its lagging like crazy.

try what conqu1stador said with the watchdog app and if you still cant figure it out, try a different kernel.
Yeah i got the lite version. It looks like a very very nice app. Thanks for your replys.
Sent from my PC36100 using XDA App
So it just happened again, finally. I looked at Watchdog right away to see what was causing it, and turns out it wasnt an app at all. Its "Android System". Now, to be honest, im not really sure what that means ( im guessing it means my rom or OS or something like that). Can anyone shed some light on what is happening?
If it matters im running myns 2.2 rls5, and kings #9 kernel.

I was having a similar problem, figured out it was the stock voicemail app, froze it with TB and problem went away.

More than likely you're having the dreaded wakelock issue caused by the combination of baseband 2.15.00.11.19 & PRI 1.90_003. Downgrade your PRI to 1.77_003. That should alleviate the wakelock and battery drainage. If you do not have this combination, download and install the aLogcat app. After initiating the app, look for and pay attention to anything colored in red.
Only time this happens to me is when my phone is syncing my accounts

CM7 android system too high.

Okay so I noticed that even with the Tiamat kernal my battery life hasn't been great. I always see above 60% android system usage. I recently did the "GPS FIX" but I never upgraded my pri or NV. I need some help, I may skipped a step.
Sent from my PC36100 using XDA App
I would update all of your radios. Also, I think in settings under privacy, unclick back-up. Also, have you considered turning down how often your phone syncs?
It also could be a rogue app stealing resources... Let's start with my first suggestion, radios are in my Sig.
Sent from my PC36100 using XDA Premium App
Okay this is weird, I turned off background data and now no system use. Is that saying it's a rogue app?

How many days was it high android use?
Sent from my PC36100 using XDA Premium App
Ever since I flashed the GPS fix but possibly after Google+ app. Either way its at 81% usage.

It's still high as hell ATM. 77% consumption. I don't understand. Wish I could get some help.

There is a fix for it you'll have to search for it I only saw it once
Sent from my PC36100 using XDA Premium App
Someone had a link for me in their sig but they changed it...and I searched to no avail. Sad cause I don't want to ditch cm7 for something so dumb. Just want my GPS to work without having my android system through the roof. Myn's Warm TwoPointTwo is on the other line. -.-
Sent from my PC36100 using XDA App
I had the same problem. Here's the fixes I did before I finally just ditched CM7
I updated my radios (and everything else).
All my syncs were on 4 hour intervals (except weather = 1 hour)
lowered screen brightness
uninstalled facebook, g+ and gVoice (my 3 highest used apps).
rebooted about 6 times
held it wrong
prayed to the gods of android
flashed Synergy RC2
So if you were considering doing those, don't. They aren't the problem.
Ironically, my GPS has never had a problem on any aosp rom (and I've tried darn near all of them), but like you, even with the kernels my stuff just wouldn't work right. I think it has something to do with our phones just not liking the kernel. Give toastch's "godmode" kernel a try or flash back to stock to see if that helps.
Ok so switch kernals or just switch to synergy?

Take a look at these battery stats: all of a sudden, my battery life is crap!

So, I've been using CleanGB 1.1.2 for a few weeks, and I tried flashing a cm7 rom. Didn't like how much issues I was having, so I restored my old CleanGB rom. Ever since, my battery life is pathetic. I have an extended battery, usually charge it from 40% to 100% while I sleep. Now, its always charging because it dies so fast.
Take a look at the links, anyone have any answers? Thank you!

Try wiping battery stats....
If you don't know how the process works you can look at Qbking77's video on it- http://www.youtube.com/watch?v=JbYVv4nCveM
Percentages don't tell us anything. What is your display on time? What is listed in running services? How much deep sleep is your phone getting? These are all that matter, not the battery screenies.
If you have 30 minutes screen on time with high intensity and are syncing something in a poor signal area that percentage is typical. If your phone is just sitting there and it drops that much an hour later then there is an errant app not closing.
Wiping battery stats does nothing... id recommend follow kenny's advice here, we can't really help you if you don't help us help you =].

How can I prevent apps from opening in the background? Like, games for some reason are in my backgrounded apps. I never opened that game, so why is it starting?
Any advice on making sure these apps don't start unless I make it start myself?

Problem is clear, all stats are fine except android system and display,no way is display that low it should be at least 60% the higher the better as it uses the most battery out of the lost batt, android system is way to high and I don't think there is a way to check what exactly it is, I would say flash a new rom.I had abnormally high cell standby and the other cell think I forgot the name haha, flashed a new rom (reaper 2.2.2) and I've had normal stats with display using the most.

They preload part of their code so that they open quicker when you want them. You can either use Autostarts to stop them or get paid version of Titanium Backup and freeze them until you want to use them or uninstall them.

That is just a misreport. It groups everything the phone does (basically being on except deep sleep) into Android System. The important stat is Display time.

Maps draining battery

All of a sudden I've been getting less battery life. When looking at the programs that are using the battery most, Maps has been near the top of the list. The thing is, it does this even when not using the maps app at all. I've tried force closing, but still pulls CPU and drains the battery.
Running Blazer 4.1
Thanks

I used to have that same problem, try uninstalling the updates on Maps and turning your GPS off until you need it. Hope this helps.

What's your screen on time.
Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.
