[Nexus One Q&A, Help & Troubleshooting] chris6647:
Hello,

Below is the message i wrote on the google support forum, but i havnt gotten a single reply yet, so i turn to you guys, in hope that you're able to help me :)

I have been experiencing this issue on and off for the past month or two. The issue being, that something called "Android OS", in the battery usage list, is eating up all my battery.

An example is, currently my phone has been unplugged for 1h30m(im down to 69% battery life remaining after i unplugged it at fully charged 100%) where the battery usage is ranked as follows:

Android OS: 72%

Display:18%

Wi-Fi: 2%

Cell standby 2%

Android System 2%

and so on and so forth.

The reason why i wrote (kernel) in the title of this question, is, that with the app "Powertutor" i have been shown that the main "app" or proccess eating up my battery, when this "Android OS" is eating up my battery as shown in the Battery Usage list, is the Kernel. Right now is shows the kernel is using 84,3% of the energy usage, Handscent has been using 3.1% and so on.

Often a reboot will bring the phone back to normal and the Android OS issue goes away for a while. A friend of mine, however, who has the exact same phone as I, has this issue, almost all the time, and a mere reboot doesnt seem to do the trick for him. His phone only lasts 6-7 hours tops, where it most of the time is just idle, and he isnt using the phone at all. While mine, when the Android OS issue isnt present, last up to 20 hours on a single charge, when i dont use it much.

When the Android OS process is eating up all the power, the phone grows really hot as well, and the difference is easilly felt. So when i feel that my phone is hot like that, i automaticly think "oh, time for a reboot".

I've been unable to find any info regarding this issue on the internet, and therefore I'm unsure what to do to fix it for real. Tried several factory setting resets on my friends phone, tried not installing many new apps, formatting the SD card, formatting the phone from bootloader (still testing his phone to see if this worked properly)things like that, but always, the issue returned, as on my phone where it only pops up once every other day.

Hopefully, someone will be able to help, or shred some light on the case.

Thank you,

Chris

Having Exchange sync on, by any chance? Try turning it off for a day, see if it helps.
[Nexus One Q&A, Help & Troubleshooting] chris6647:
"Exchange sync" being exactly what? The basic sync function on the phone that can be enables and disabled? The basic sync with your google account?

If thats the case, then yea im having that on all the time, so that it may sync whenever it wants to. The sync icon doesnt appear that often though, so cant see how this could be the reason why. But if you come back to me and tell me that this is what you meant, i will definetly give it a try :)

Thx for responding
[Nexus One Q&A, Help & Troubleshooting] Jack_R1:
No, Exchange sync means - MS Exchange account (in addition to your default Google account) that syncs calendar/email/both with Exchange server.
[Nexus One Q&A, Help & Troubleshooting] chris6647:
I'm guessing again that that is something extra you must install / set up, which i have not done. The only two accounts i have that can sync are my facebook and my default google account. I never sync the facebook one though.

Edit:

Update:

Reinstalled Watchdog Lite today, since my phone has been exceptionally sluggish, and SeePU graph keeps showing a full graph on cpu usage. I've had to reboot it twice today, in hopes of it returning to normal state. It does for a while, but then returns to a slow state where Android OS uses like 80% of the battery.

I made Watchdog Lite monitor the base android processes as well, and right now it keeps warning me that the "Base System", "Linux Process" uses up 89,6% of the CPU and 10,3MB of RAM, while nr 2 on the list is Android System, Foreground, with 3,8% and 27 MB.

I feel like the state of my phone is worsening, and I'll prolly do a full factory reset(again)/format of everything within a few days if i cant find the root of the issue this time around.

Please help :( I love my phone and i want it to be healthy again.
[Nexus One Q&A, Help & Troubleshooting] lbcoder:
"OS" is an abbreviation for "Operating System". That means ALL of the background stuff that eats battery and CPU time that isn't attributable to a process or function easily understood by the typical user. This includes, yes, the Linux kernel, but also all the other background things that your phone does in order to continue functioning in a normal synchronized state...

Your phone has a CPU. The kernel has a process scheduler, which swaps different programs in and out of the CPU in order to make it look like it is running more than one thing at a time. Each clock cycle consumes some amount of the power from the battery, so if it assigns 10 cycles to process A, 10 cycles to process B, and then waits for 20 cycles for I/O synchronization, then HALF of the power consumed in those last 40 cycles (attributable to CPU) will be "Android OS". Clear?
[Nexus One Q&A, Help & Troubleshooting] chris6647:
Alright, I was wondering exactly what it meant when it just said Android OS, just that seemed like quite a broad description.

But what your saying is that it may be other applications that is actually eating up the power, just the kernel assigning the power to the program, and therefore the Battery Usage shows the kernel/Android OS as the culprit?

If its the case that its an app then, that through the kernel is triggering the usage that drains my phone, then how come my friend had this issues with an almost "naked" phone? He had installed just a few apps and still ran into this issue.

Am i understanding what you're telling me correctly?
[Nexus One Q&A, Help & Troubleshooting] khaytsus:
It's not normal, something is causing it. Most likely some poorly written app or some other weird thing is causing the "Android OS" (which I assume is likely the virtual machine itself) to do bad things.
[Nexus One Q&A, Help & Troubleshooting] chris6647:
Today the linux process "init" has been hogging up all my phones resources, as in 77%+ of all the CPU usage :/

Was wondering if rooting my phone and installing/ flashing some custom rom would solve the issue for sure? Or should I send the phone back to the states for at checkup or repair? (dont think this is needed but now I ask anyway)

Is there an app that could track down exactly what is sucking my phone dry? Cus all that I've found are those broad references or processes :/

Thx for all your responses :)

[Nexus One Q&A, Help & Troubleshooting] Jack_R1:
There is no solution, because you can't track the app that is causing the system to hang.

You can uninstall all the latest installed/updated apps and install them one by one, using Titanium - and that'll pinpoint the offender.
[EVO 4G Q&A, Help & Troubleshooting] saucratiz:
Whenever I use wireless tether in a 4g area on sweetest on my phone I am getting speeds over 6mbs, but once I turn on tether the device can only reach speeds of around 1 mbs, download just wondering and if it has to do anything with the 1 mbs upload cap on 4g
[EVO 4G Q&A, Help & Troubleshooting] mallman:
sounds like wireless is only taking advantage of 3g
[EVO 4G Q&A, Help & Troubleshooting] Dees_Troy:
I am pretty sure that android wireless tethering uses the 4G connection. I ran into the same issue with mine though. My 4G connection directly on the phone could hit 8Mbit, but I couldn't even get 1Mbit on my laptop. The reason that I'm pretty sure that it's using 4G though is that I can make and receive phone calls while tethering and still browse different pages which shouldn't be possible on 3G-only.

Based on this fact, I moved to CM6 since the speeds while tethering really aren't that much different. Hopefully the CM team will get 4G working soon, but I'm not getting my hopes up.
[EVO 4G Q&A, Help & Troubleshooting] BlueScreenOfTOM:
I had this same issue. A dalvik cache wipe seemed to clear it up, and 4G went back to full speed over tethering.
[EVO 4G Q&A, Help & Troubleshooting] Jackdup:
I have the same issue. My solution has been to stay on 2.1, because on 2.1 the sprint hotspot feature is free, which actually tethers at the full 4G speed. I am assuming the problem lies within the 'wireless tether' application code, but I don't really have a clue.

Saucratiz: Did you find a solution? Did wiping the dalvik cache work for you like it did BlueScreenofTOM?

This is the first thread I've found on this issue, and I've wondered why nobody else has brought it up. It must be because most EVO developers/users don't live in 4G areas. It's a big problem. I wish someone would port the 2.1 version of Sprint Hotspot over to a custom 2.2 rom, or something like that.

Would LOVE a solution to this problem.

then why do they charge 29.95 for its use?
[EVO 4G Q&A, Help & Troubleshooting] Shauli20:
It's unofficial. Sprint doesn't actually acknowledge that the Hotspot is free on 4G, and also it's only free on 4G not 3G.
[EVO 4G Q&A, Help & Troubleshooting] t3project:
that's kind of retarded on their part. charging for 3g hotspots and not 4g. but none-the-less, thats great for 4g areas/users which dont exist around here. :D

I tested mine just yesterday and had a connected laptop downloading data at speeds in the 2.5-6.0Mbit range. I'm set up with fresh 3.1.0.1 using netarchy kernel 4.1.8 and my wireless tether version is 2.0.5-pre8.
[EVO 4G Q&A, Help & Troubleshooting] Shauli20:
Maybe it's the kernel? I'll try Netarchy's 4.1.8 when I get a chance.

Guys, can you please post which kernel you're using so we can see if there is a pattern?
[EVO 4G Q&A, Help & Troubleshooting] Jackdup:
I'm on stock rooted 2.1 (kernal/info image linked below)

I live in 4G, and only get about 1MB tether speeds with 'wireless tether'. I've tried every version of it.

A side question: Is the only way to get AOSP tethering, to go to CM6? or do certain kernals bring the AOSP tethering functionality to your phone, too?
[EVO 4G Q&A, Help & Troubleshooting] Shauli20:
If you're on 2.1 you shouldn't be needing Wireless Tether. The built in Hotspot works on 4G only, without paying, only on 2.1. Don't ask me why, but it's a known thing and it worked for me when I was on 2.1.

Any ROM based on HTC's code will not allow the built in Hotspot to work for free. CM6 doesn't support 4G anyway at this time, so it won't help for 4G tethering.
[EVO 4G Q&A, Help & Troubleshooting] Jackdup:
You misinterpreted both points of my post.

1. I posted my kernel info because you asked people to, so we could look for a pattern. I know the 2.1 sprint hotspot works for free on 4g, that's the only reason I'm still on 2.1 ... hence my interest in this thread, and figuring out a solution to the 'wireless tether' 4g problem. Get it? The reason I explained that I lived in 4g, and only got 1MB speeds from 'wireless tether' is so we could associate my kernel with 'wireless tether' not working well on it. It would be pretty lame if everyone posted there kernal info with no mention of how well their 'wireless tether' app worked with 4g speeds, now wouldn't it?

2. I didn't ask about using CM6 for 4g tethering. I don't know why you thought that. I know CM6 doesn't support 4g. I asked if flashing a custom kernel could enable the AOSP tethering function. Do you know if they do/can?

Also... why do you say any ROM based on HTC's code will not allow the built in Hotspot to work for free? I am currently running a rom based on HTC's code that DOES allow the built in Hotspot to work for free. So it seems you are clearly wrong about that assumption. Why do you say that?

I hope other people post their kernels so we can look for a pattern, like you originally suggested.
[EVO 4G Q&A, Help & Troubleshooting] Shauli20:
My bad. But when I said that any ROM based on HTC's code will not allow the built in Hotspot to work, I meant only 2.2 ROMs.

Your kernel says htc-kernel@___. So I assume it's stock?

I've been using several of King's kernels and they all have the slow 4G issue.

[EVO 4G Q&A, Help & Troubleshooting] Shauli20:
Yeah, I have an idea. You're not paying for the Hotspot so it's shutting down on you.
[EVO 4G Q&A, Help & Troubleshooting] hsmith1514:
i also have this issue. 4g speedtest from the phone is anywhere from 8-11mb/s, yet when i connect to wireless tether, it dropps to less than 1mb/s. mine is just a standard root method, then flashed the stock rooted 2.2, no custom ROMs or kernals beyond that. ive also tried older and new radios, all with the same results.
[EVO 4G Q&A, Help & Troubleshooting] Jackdup:
I flashed 3 roms this weekend, with the included kernels. I found a partial solution. Here are my results:

1. Fresh 3.2 with included new stock HTC kernel. Getting 0.5mbps tethering download speeds on 4g.

2. Vaelpak 2.1 with Kings BFS9 kernel. Got ~1.3mbps tethering download speeds on 4g.

3. BurntDroid 1.1 with netarchy-toastmod kernel revision 4.1.9.1-cfs. Got 2.4mbps tethering download speeds on 4g. But only 0.1mbps upload speeds. You might think this is acceptable, but I was getting 5.4mbps download and 0.8mbps upload directly on my phone.

That's all for now.

What's everyone else getting?
[EVO 4G Q&A, Help & Troubleshooting] Niviac:

[EVO 4G Q&A, Help & Troubleshooting] Jackdup:
Using PDAnet via USB gives full-speed 4G speeds through tether. It is a problem with 'Android Wireless Tether'. Also, of course, using Sprint Hotspot gives full-speed 4G speeds through tether, too.

There is an 'issue thread' on 'android wireless tether' google code website. We should all make sure to put our comments there, (AND VOTE FOR ISSUE), so it gets upgraded to a priority issue. That is the thread that will really get a solution in the works from the developer. Here is the link:
