Root Using Netarchy kernel on Fresh 3.2... Insane battery drain...

Ok so the Rooted OTA works nicely as it has the fps unlocked and such BUT...

In idle with setcpu underclocking, I get like 1% drain per hr. Good stuff.

In on-mode, it heats up like mad and drains battery very fast. Even when 50% underclocked.

What kernel are you using? Because I gathered that you are using the stock kernel, which means setcpu doesn't work. Just wanted to make sure you knew that.

SetCPU works after perflock is disabled? No?

In any case. Stock stock stock. No fresh rom, nothing.

I think actually since I have an older version of the radio, due to my flash, I might have higher drain. I will try the newer radio rom out.

So many variables.

Has anyone had success troubleshooting such issues like I have, insane drain when using a non-stock kernel?

Also when flashing a kernel, do you guys always flash, wipe battery stats, and only when charge is full?
 
Ok hopefully this gives some insight into my battery operation. Its stable at the moment, but much higher drain than I would hope. About 1% on idle, when not idle it drains like 10-20% per hr.

Cell standby -- 31%
Android System -- 28%
Phone idle -- 28%
Display -- 9%

There are other % but those are very minor. I played a game so its marked as 4%.

The only thing that seems to always drain a battery fast, no matter what rom or kernel, is a weak 3g signal. If your "time without a signal" is high under the cell standby section, that would be a big battery killer.

And you are disabling perflock in setcpu upon every single reboot, right? That was what I couldn't remember. You can disable it on the stock kernel, but it has to be done every time the phone is rebooted. Unlike other custom kernels......

From what I can tell the problem is that the gpu starts to create tons of heat and drais battery which explains the ultra low bat usage when idle. Basically the second it comes out of sleep mode, it gains maybe 5 degrees celcius in heat, well in maybe 15 seconds. Even when just looking at the main screen doing nothing. HOWEVER when idle we are running at 1% per hour. When using applications the drain speed is pretty consistent, heavy games take a bit more battery, but were talking about probably 2-5% difference in usage, where 20% per hour awake is the normal mode of operations.

Whatever happened during the update, the kernel works great, the GPU appears to be the main problem. Is there seperate driviers for the GPU? Or is that all baked into the kernel?

That does not explain why the battery drains so fast... It drains fast even when 3G antenna is turned off and wifi on (and there is a connection). I mean when without signal playing music it drains 1% (using lowest CPU settings, and obviously GPU off) when turned on, it drains more in a minute than an hr off. Drains 1% idle even in the subway with 3g on looking for a signal.
 
i have no idea then. All these phones seem so different. I just realized that, for the first time ever, my phone wasn't sleeping. 4 hour uptime, 4 hour awake time. There were no abnormal running services. I did nothing different. These phones just make no sense. My spare parts told me it was "android system." Thank you, that really narrows it down for me, a-hole.

Put your phone in airplane mode tonight when you sleeping you will see what's. Up
 
a reboot fixed it, but what a pain in the ass to have one more thing to keep an eye on. sometimes i miss my flip phones
 
In any case, maybe I am wrong, maybe this is just the normal battery drainage of the phone. I think I can get approximately 4-5 hrs of active usage (internet/games) on the phone, while standby the rest of the day. It should last me all day then. Which basically means that it is good enough for me :P

If that is the case I'm just gona get the extended battery and be done with it.

Current its up for 12 hours with 2 hrs of extremely heavy use, and 2 hrs of medium-heavy use. And from 16% im trying to kill battery. It should be good enough I think :) Still want to know how the folks at fresh got to 1d 13h.
 
The great android god has smiled upon me today. Apparently not only have I been able to get 12 hrs a day for the last 2 days on my phone (with 4-5 hrs of heavy usage and about 10% battery drain due to deliberate usage to kill battery), but after installing the netarchy cfs 4.1.9.1 kernel I am getting about 30% decreased energy drain during active time without underclocking.

Wow!

Using clockwork recovery at the moment.

This comes after I deleted battery stats. However I am unsure how much effect that had to do with my battery consumption. We shal see. And I cleared cache/dalvik cache.
 
Funny, I switched to try king's kernel. I was getting some random awake time issues that had no explanation with that cfs 9 by netarchy. King's cfs 9 is just as fast, but I get better battery life and no awake issues. I'm at 24 hours on a single charge with the stock battery and still have about 9% left. I'm underclocking to 729, but I never notice a difference anyway. You should try this kernel and report back.
 
I'm having the same issue with battery drain when in use using pretty much every kernel that I've tried after updating to the new radio/PRL. I am using Set CPU.

I've tried 4.1.9.1 (cfs and bfs), 4.1.8 (cfs), and King #10. The idle battery is fine, but as soon as I use the phone, the drain is ridiculous. I'm losing percentage points every time I do something on the phone, even if it is simply scrolling through e-mails.

I'm not having wake time issues, the phone sleeps fine, but this is extremely frustrating.
 
So i'm at my wit's end here. I can't get any other kernel to load. i've tried all the forum directions on loading a kernel but end up having to flash the rom back (fresh 3.2). i've tried the modified pc36img file, tried the original pc36img file, tried the hboot file. nothing seems to work. I couldn't even get out of the bootloader loop with any of the pc36img files. when i load up in hboot it looks for the pc36img file on my sd card (which is there) but it says no file or wrong file.

All that being said, i've tried to get the eng bootloader to work so that i could put different kernels on but to no success...i think. every time i try to load a kernel and yes i do wipe cache, dalvik cache and wipe battery, it hangs on the htc evo screen and i can't even do a recovery. it says it fails. i have to flash the rom again. it looks like it should be the correct version of the bootloader, this is what it says:

supersonic evt2-3 eng s-off,
hboot 76.2000 (pc3610000),
radio 2.15.00.09.01

i am running kernel 2.6.32.15 htc-kernel
version 2.2
build fresh evo 3.2.0.0
pri 1.77_003

i just want a rom with a nice kernel that has good battery life and can't seem to get the right combo of rom/kernel.

could anyone give me like baby step instructions or something? or point me in the direction of a good instruction set that i could follow please? i'm pulling the last 2 hairs i have left on my head out. thanks, sorry about the long rant.

What did u do to get in this situation, what did you flash, update to get it to not boot, can you get into recovery, do you have a nand backup?

Also, bootloader doesnt flash kernels or roms, you need recovery for that
 
well i originally flashed the fresh 3.3 rom but couldn't get another kernel on there until i had eng bootloader. or at least that's what i read. so i spent a few hours trying to get that bootloader on there last night but could not do it. yes i can get into recovery and do have a nand backup but when i try to load kernels and they don't work i can not recover. it gives me an error when loading the backup so i have to reload the rom all over again

Sorry i guess i misspoke. i'm using clockwork and i do go into recovery when flashing a kernel.


wake...yes it boots up fine once i reload the rom file. i'd just like a nice rom/kernel. if you could help me out that would save my blood pressure from hitting the roof
 
how did you root? how long have you been rooted? if you could flash recovery generally you have eng bootloader
