Switching to NV & PRI v1.77_003 worked for me

I was running the latest radio combo pack from Calkulin and i noticed my phone would go dead in 8-10hrs. My normal usage is about 18-24hrs on a charge. So, here's some screenshots of juiceplotter. It confirmed that something was up.

==Running Latest Combo==

==Battery usage==

==Constant drop off with screen off==

==Downgraded to EVO_NV_1.77_0033 & EVO_PRI_1.77_003==

Amazing! :)
[EVO 4G Android Development] JBabey:
Bizarre, I will flash 11.19 radio on a few devices and report back. what program are you using for temp and graphing?
[EVO 4G Android Development] MizzouBrent:
JBabey, I'm wondering if my reboot/battery life issues as of late have been the result of the newest radios as well. Like dirky said above, my phone has seemed hotter (although the temp reading on Battery Indicator has not seemed out of the ordinary) since installing the new radio updates. I just flashed the radios that I had been running, the ones from HTC's November update. I will let you know how it goes.

Battery Indicator had shown temps at most of a shade over 100F or maybe a little higher during heavy use. I have never had random reboots but I've had maybe 8 or 10 in the last week or so. It could be totally unrelated to the radio, but I think the alternative is some kind of hardware failure.
[EVO 4G Android Development] lowspeed:
can you clarify this ? "Now..... REBOOT the phone when you pull it off the charger. "

You first initiate reboot then pull ?

or just pull it and reboot ?

or pull it after the shutdown?
[EVO 4G Android Development] lowspeed:
Why not just delete the battery stats ?
[EVO 4G Android Development] Biggie Da Dansa:
i tried to get amora recovery but it didnt work i have clockwork and it up dated and i dont have option to update UID mismatches.. so is it a big deal if i dont update after flashing VIsion driver?>
[EVO 4G Android Development] cheapskate88:
JBabey, thanks for looking into this for everyone.

wanted to let you know that your directions work well to remove android system usage, but once I make a phone call, like others have mentioned, android system usage jumps up to around 30 percent.

Android system is hovering around 60% now

I'll try the whole process again after I flash the latest stable of deck.

Edit:

For a second there, I thought a full wipe actually fixed it. But unfortunately, that isn't the case.

After 2 calls, each about a minute long, I'm getting high android system usage, right around 40%.

Not working at all. Charged over night. Woke up made a call. Rebooted. 81% system.

[EVO 4G Android Development] BilliardCoach:
Cheers. This procedure worked for me nicely. I used Clockwork and am running CM nightly 107.
[EVO 4G Android Development] JBabey:
That is not something I have come across. Since the post I have updated a lot of my co-workers handsets and they are not seeing this issue neither. Unfortunately I do not know how to begin troubleshooting that issue until I get a phone into the tech room that is having that issue, that a customer can leave overnight. The return phones I have been testing on I have to push out every couple of days, and they are not-capable of making phone calls as they are returns, broken, etc.

Ill ask around the store and see if any other people have noticed the issue.

What ROM are you running

What is your recovery

Which Radio PRI/NV are you running

Which GPS driver

Have you attempted to change GPS drivers, I personally use the Kingdom on Cyanogen Nightly 108 (atm), and I dont experience high CPU usage.

Clockwork has it under the advanced menu, you can also fix permissions in the clockwork app on the phone once your booted into the operating system.
[EVO 4G Android Development] DaKlown:
Glad someone else made a post about this. I was also at my wits end with this issue. The fix that the OP describes does fix something for my phone but not everything. Until I flashed these radios and the old pri my battery use screen only showed like 4 items with android system always being in the 70s or 80s. Now at least other apps that use my battery show up but like a lot of other people here my android system shoots up after phone calls but it no longer shoots up into the 80s. After a full discharge of my battery through a days use the android system sits at about 40-50%. One thing I have noticed is that the *#*#4346#*#* trick i found on another board seemed to help for a while but the fix doesn't stick. Nor does the airplane mode while on the charger fix work. Is there something on AOSP roms conflicting with the radio files making the android system shoot up like this after making calls? I've never had this problem once on a sense rom. The reason i believe its a radio issue or some conflict in quickly switching off data to make calls is because when I turn off data before I make a phone call the highest the android system will jump up to is in the 20s-30s which is probably more correct. Also in another thread someone said that using older kernals based off of the cyanogenmod 2.6.37.4 kernel fixed this issue for them as well... i have yet to switch kernels but that is definitely my next test.
[EVO 4G Android Development] Biggie Da Dansa:
I got everything working good.. no more android os at the top.. but I feel my battery drops eay faster than before I updated.. im on cyanmod nightly 107 running savage kernel.. any sugestions
[EVO 4G Android Development] catseyenu:
How would I determine my current NV version?
[EVO 4G Android Development] Mazda:
That's what I've been trying to figure out....I've tried Google, searching on here.....I even called Sprint (they acted like I was speaking german or something).

I PMed JBabey, hopefully I get an answer here shortly and I'll share the "secret" with Y'all...hahahaha
[EVO 4G Android Development] catseyenu:
Current software.
[EVO 4G Android Development] imheroldman:
@Catseye, no NV on that list

Evo 0003, Decks 1.2, Tiamat, Vipermod
[EVO 4G Android Development] JohnBecker:
I am utterly amazed! I upgraded to Deck 1.2 this morning and did this fix for the radio. I'll be honest, I was ready to scrap the ROM and try something else after losing bluetooth connection 4 times during the prior day.

I didn't do a complete wipe. I've actually got my phone the way I like it and didn't have time to set it up all over before work this morning. So I took a gamble and cleared the cache, did the radio fix using the CyanogenN39 and the NV 1.77 fix. Then I flashed the new ROM.

After 1 full day of using my phone, I've seen the following:

* Not one dropped bluetooth connection

* 14 hours of battery life with my BT turned on all day long. I've never gone more than 11 hours without having to change or charge the battery. I still had 38% life left after 12 hours. It's usually down to 10% by that time. (I spent all day in a very low Sprint signal area today too, which normally drains the battery)

* Quick responsive device with no hang ups at all. This includes not having to swipe twice or more to change screens after turning on the device.

* It's always turned on normally without having a dark screen

I've had trouble with the radio in the past and so far this is working great! I use my phone for business, so it must be reliable or I can't function. It's the best combination fix I've ever seen and I'm so happy right now.

THANKS!

PS: My PRL still shows up as 01115 tho, even after the update.
[EVO 4G Android Development] Mazda:
You're PRL is not effected by this COMBO of PRI/NV/RADIO/WIMAX/GPS........
[EVO 4G Android Development] cheapskate88:
That's interesting that youve never run into high android system after phone calls. I always thought that phone calls were exactly the reason for the high android usage.

I'm running Deck's latest stable, 1.2. I run Tiamat's 4.0.5 with SBC. I use Among Ra 2.3 test build 4 (never got around updating to the final release, but they should be identical). I'm running your hboot zip for radio, etc, and I ran the 1.77 NV.

I tried the kigndom fix before but got hit with high CPU usage, so I'm using the Vision.

I run vipermod 2.4 -50mV and Supercharger v6 (latest update).

Hope some of that is useful. Let me know if I can help with anything else!
[EVO 4G Android Development] Mazda:
Well after almost pulling my hair out and getting close to just say FU#K it......I got it to work! I got rid of the stupid Android System/Android OS showing up in my battery use.......

I followed everything down to the letter BUT this time after making the phone call and making the Android System jump to 5% or so (mines jumped to 11%) I didn't touch the phone unlike the first time where I began to play Angry Birds, XDA app and just using the phone as if nothing was going on.......After about an hour or so, the Android System/Android OS is completely gone!

I also made sure it was gone completely and made a phone call to my sister and I confirmed is GONE!!!

[EDIT]

The only bad thing about all of this is the battery drain.....got to figure that out, not sure if is all the widgets and crap I got on my homescreen/display brightness or what, BUT I'm happy and so is my wife because is gone on her EVO too!!!
[EVO 4G Android Development] wryun:
I just flashed Deck 1.2 as well. Are you using a custom ROM, or the one that is built in to Deck1.2?

By the way, why is it bad to see Android OS or Android System in the battery stats? How does not having those show up in battery stats improve EVO's life?
[EVO 4G Android Development] Mazda:
Having Android OS and Android System is pretty much the reason your EVO can't sleep properly when you turn the screen off which means your battery drains as if you had it turned on SOOOO having Android OS and Android System not show up means your "Wake" issue will no longer be a problem or that much of a problem and your battery WILL improve........properly not right away but I got a feeling after a full drain and charging it up back to 100 percent, you should start noticing the difference.

Of course, you still have to follow the battery saving tips such as turn your brightness down when you don't need it......turn off 3G is you don't need it on and things like that BUT this combination of radio/nv/pri/wimax/gps has to be the greatest thing that has happen to my EVO since CyanogenMod 7...hahaha
[EVO 4G Android Development] wryun:
Alright, I am about to re-flash Deck's 1.2.

Is it best to apply this "fix" before flashing the custom ROM, or after?
[EVO 4G Android Development] Natedog1:
I had the same problem. My problem was the gps drivers caused the cpu to run at 100% constantly. Try using the cm n39 gps drivers in the op and it might do the trick for you too.
[EVO 4G Android Development] Mazda:
I would flash your custom rom first because here the thing.....you're going to be flashing a different Radio/NV/WIMAX/PRI then after that you'll flash a GPS driver depending on what rom (AOSP or SENSE)....in your case it'll be AOSP so you don't want to flash the radios and stuff plus the GPS driver only to flash another rom on top of that.....you feel me?..hahaha....GOOD LUCK
[EVO 4G Android Development] wryun:
All done! Now it's time to wait to see the results.

I am using Deck's GB 1.2 with SavagedZen-2.2.1-CFS-HAVS.

Thanks for the help.
[EVO 4G Android Development] JohnBecker:
Deck 1.2 IS a custom ROM. However I assume you're talking about a kernel. I'm using the kernel he's included in the ROM. I tried others before, but didn't have any better or worse luck. Everything drains a battery. Some radios drain faster than others, especially in low signal areas. If I'm roaming, consider my battery to be dead in just a few hours. I've never had my phone last 14 hours using my BT all day long. Whatever the combination does to this phone, it really works! As much as I like Deck's ROM, I won't say it has much to do with the battery life. It's been the same for me since version 1.0 (and I've done every upgrade since then too!)

It may take a few days to really see how the phone works now, but I'm happy. I might end up doing a full wipe Friday night and starting off clean just to be on the safe side. I've gotten pretty good at putting it all back the way I like it again rather quickly. I just hate losing my phone history when I do that.

Now if 4G were up and running in Louisville, I'd be much happier. They show partial coverage in town, but someone must have been drinking heavily when they drew up that map. It's not functional except in maybe a few 100 sq. foot areas. Its discouraging that my extra $40 a month (we own 4-4G phones) is going nowhere. My luck, Sprint will change to LTE and drop Wimax before I even get to test my phone at a higher speed.
[EVO 4G Android Development] DarthBelan:
I'd like to clear something up, you are not eliminating the Android OS or system usage, if you were your phone wouldn't work. You're fixing a bug that causes the Android OS to use more battery than intended. Those of you who are seeing the Android OS or System in the list with a 2-4% usage are about right, and shouldn't have to do this fix. If you're like me, and the phone isn't permanently attatched to your hands or ear, then it would be normal to see this in the list as it uses more battery than other things, even voice calls.
[EVO 4G Android Development] wryun:
Yes, I did mean custom Kernel. :-)

I ended up doing a complete wipe, including my SD card since I had it partitioned for a previous sense 3.0 ROM. I enjoy AOSP much more! Nothing too big about wiping my SD card as well, I just need to dump all of my music back on to it.

I used to use Titanium Backup for restoring with new ROM installs, etc., but I recently found that using the online Android Market goes better. I don't have to worry about previous data messing up new ROMS. I do have a few apps that I want data to stay with, so I still use TB.

Anyway, thanks for clearing up for me. I am good to go!
[EVO 4G Android Development] bytes2bits:
I can't for the life of me understand WHY this works but it absolutely did in my case. The really odd thing though is that I did a Nandroid backup right after I had this working. Then I updated to the latest Evo Deck and started getting the Android System showinfg up on my battery usage again. I immediately restored back to my Nandroid backup and yet the problem was still there. Once I repeated this fix, everything was back to perfect. Why didn't my Nandroid image still contain the fix? That's the really confusing part for me. In any event, great job on this fix OP. I just wish I understood the mechanics of why it works :)
[EVO 4G Android Development] yungd83:
I.dropped 10% in 6min made a call less then a min, opened xda and posted this
[EVO 4G Android Development] yungd83:
Oops

[EVO 4G Android Development] MizzouBrent:
For what it's worth, I did this fix and then downgraded my radios back to the November HTC update and am using the Vision GPS driver, and my Android System usage is not showing up anymore. Using Deck Stable 1.2 and the regular Cyanogenmod Kernel.

Great work by JBabey to figure this out.

Also, the Kingdom GPS driver was causing 100% CPU usage for many, so make sure to check that first if you guys apply the fix and see your phone acting strange.
[EVO 4G Android Development] yungd83:
What other gps fix can i use?
[EVO 4G Android Development] webfeind:
Are the GPS drivers for GB roms only? I'm using SprintLovers 2.2 and this GPS file doesn't exist. But I do have the very high Android System usage issue. And does this fix work on the 2.2 roms?

Thanks,
[EVO 4G Android Development] fitz420:
So I'm a bit obsessed with trying to get the android system out of my battery stats.....I don't know if I should be though. I'm running Decks 1.2, SV 2.2.1, and ViperBoys UV script. My battery life has never been better. Even though my android system is high in my stats I'm pretty sure I'm not experiencing wakelock. I can leave my phone unplugged at night and only loose 1%-2% over the course of 7 hours.

I've tried this method, including the NV downgrade and the different GPS fixes. My GPS isn't pegged at 100% and works great. Nothing seems to work, but again, I don't know if I should even be trying. My battery life is astounding but I'm still wondering if it could be better. IDK, what do you guys think?
[EVO 4G Android Development] wmblalock:
Ok, this fixed my wake issue / android system battery drain issue. It did not work the first time, but it did work the second time when I used the second method that required me to flash the 1.77_003 NV file.

Now I have a GPS battery drain problem, when using GPS/Navigation, it eats my battery down at about 1.7% per minute, which is really bad. I stated a 10 minute trip at 94% battery and when I got to my destination 10 minutes later, I was already down to 77%. I don't remember GPS ever eating my battery this bad. I am using the Qualcomm Vision GPS driver that was flashed during the fix from this thread.

From what I understand this is the same driver though that comes with Deck 1.2 rom that I am using, so it shouldn't make a difference. Is anyone else seeing this huge battery drain when using the GPS??

Any other drivers that may be better for the gps? Any suggestions? I use Navigation a lot and hate to plug the thing in every time...

[EVO 4G Android Development] Tattrpuff:
So here's my experience with this, I am running CyanogenMod Nightly 108, Cyan Kernel. I was having the 55% Android System at the top and horrible battery drain. I tried this fix as written and it did nothing the fist time. I tried going through again and it did get rid of my Android System, made a phone call, rebooted this time wiped batt stats...this made it so it only popped up to 4-5%, never disappeared. By the end of the day...it was back up to 55%. So yesterday I did a full wipe and started completely over with CyanogenMod Nightly 108, Calkulin newest combo radios...by the end of the night I was at 46% Android System.

So I bump charged it wipe the stats this morning, downgraded my radios to the combo EVO_Radio_2.15.00.11.19_WiMAX_27167_R01_PRI_NV_1.90_003, downgraded my GPS driver to CM7-N39-GPS-Driver_Supsersonic and just for good measure downgraded my PRI to EVO_PRI_1.77_003...charged it up, wiped the batt stat and rebooted. Made a 4 min phone call, checked battery info...Android System...2%!!! Waited about 15 mins, rebooted, did a Nandroid back up...now it is just hanging still at 2%. We'll see, my battery seems to have stopped hemorrhaging.
[EVO 4G Android Development] rsatmans:
Thanks! I was really skeptical, but this did work for me.
[EVO 4G Android Development] MizzouBrent:
I think I'm on the exact same combo as you for radios/PRI, and experiencing the same results. I've been off charger for almost 4 hours and I don't have any Android System stuff in my battery use %.

There is a thread in this forum posted by Galandy with alternate GPS Fixes. If the Kingdom driver is going bonkers for you, try the Qualcomm driver for the HTC vision or the CM Nightly 39 driver or whatever it's called. If you're running Deck's newest stable, then you're already running the Vision driver because it's built into the Rom. It locks great for me.
[EVO 4G Android Development] wryun:
I am quite impressed, and a little surprised, with the results from this fix. Check out the screenshots I just took.

These are the steps I did:

1) Last night, I wiped my entire phone, including SD card since it was partitioned for a previous ROM.

2) I installed Deck's GB 1.2 ROM, the associated gapps for that ROM, latest SavagedZen Kernel and rebooted.

3) I then flashed the recommended PC36IMG.zip file, along with the CyanogenMOD 7 Nightly 39 GPS Driver (HTC Blob File Compiled) since I am using an AOSP ROM. Then, rebooted.

4) Once my battery was fully charged to 100%, I installed Battery Calibration and executed the app. Once that was finished, I unplugged my phone as recommended by the app.

5) I got my phone all setup and got my music back on the SD card.

6) Plugged the phone in and went to bed.

As you can see by the screenshots, my phone has been running on battery power for 2hrs 20min, and I am still at 100%. My phone has been sitting on my desk the entire time, and my signal is full bars. During that time, WiFi has been on the whole time without using it, GPS has been on the entire time, Gmail is pushed, work email checks every 30 mins, I have texted a few times, browsed the web for 10 mins, and made a 5 minute phone call. Also, on my way to work, I used my EVO to listen to music for 20 mins. I use PlayerPro for music.

By now before this fix, my battery would be down to at least 85%.
[EVO 4G Android Development] cheapskate88:
Do you use an extended battery? It also looks like you still have an android system problem.
[EVO 4G Android Development] neilkarunatilaka:
The original method worked right off the bat for me, except only modification I did was flash the latest CM nightly, Tiamat kernel, then flashed the GPS fix zip and then did the UID fix and restarted from recovery. But yeah, looks it works so far.. nice!!
[EVO 4G Android Development] wryun:
I use the standard capacity battery that came with my EVO.

As far as the Android System problem, from what I remember reading, it takes a while for this to kick in 100%. In this updated screenshot, you can see Android System usage has gone down from 30%. So I think within a day or two the issue will have worked itself out.

As of right now, my phone has been using battery for 4hrs 21min, and usage is at 91%.

Since my last post, I have listened to 40 minutes more music.

I am very pleased with this!

Thanks for the hard work in finding this combo and fix JBabey!
[EVO 4G Android Development] jae04cc:

[EVO 4G Android Development] SantinoInc:
Its crazy how sometimes these fixes work so well for some but have little or no effect for others. I personally am going to leave my set up the way it is.
[EVO 4G Android Development] ropodope:
This does not work. Your android system usage and wakelock are not one and the same. And while this may work for a day or two it comes back. I've had wakelock with and without any android system usage popping up and the reverse has also been true. This is a pipe dream. From te type in dumpsys power, then enter. Look at the output at the end. If your mlocks =0 and and your m.pokelocks =0, you have no wakelock issue at that particular time, if one of them has a value of 1, then you do.
