[Q] <DC CONNECT> IO error: msg='/127.0.01:7771 - Connection refused - EVO 4G Android Development

In the new OTA leaked ROM base, v3.28.651.6, this seems to be happening to many people, including myself.
<DC CONNECT> IO error: msg='/127.0.01:7771 - Connection refused
This happens after turing 4G on and then turning it off. You can see this error in logcat. and it repeats endlessly!
Does anyone know why or have a solution to this?
It has also been reported HERE.
4G works fine, it doesn't break 4G, it's just some stupid looping error.

its not just the new rom, it happened on 2.1 and 2.2 ota's.

It has been concluded that this is normal behavior, since the early builds. Apparently, that's how wimax works on the evo

That's pretty lame coding on HTC's part then. Why have something that is turned of try to reconnect infinitely to something. That has to waste resources.

It happened to me yesterday but when I rebooted I could connect and stay on 4g. Weird.

In regards to the effect of this on battery life

9pm - 4g Turned on, then off.
9-~12: screen always on, multiple reboots (4g turned on/off after each reboot)
~12pm - screen off the rest of the night (while in the error state)
The results to me look like any other day under the same usage conditions. To me, at most this is an annoyance when trying to logcat for something unrelated, but doesn't seem to affect battery like people have been posting in multiple forums.

I agree, I am at work for 14 hours a day and I come home with 35-40% battery left. Prior to this new leaked OTA ROM base, I came home with 5-10%. I use the same phone the same way, so regardless of this weird arror, battery life is still good.

Like the guy in the post that you linked to on the Sprint forum says, seems to go away if you Turn off 4G and then completely power down (Hold power button, and choose Power Off). A reboot doesn't fix it, has to be complete power down.

Agreed, it's a silly leftover, I usually just use some sort of a tail-like application, and just filter those out if i need to do logcat.
It's the 4G radio that causes major battery drain, not the repeated log messages anyway

CM10 battery drain spike

Sorry for not posting this in the CM10 thread; this is my first post and I'm not allowed to comment in the dev forum yet.
I installed CM10 (after having used CM9 successfully for a month or two) from this thread (the 8/9 build) last night.
Everything more or less works fine, but I was playing with the torch app for about 5 seconds when my phone went from ~60% charged to off:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I don't actually think it was the torch app that sucked all of the power (the "battery" section of the settings says almost all of it went toward the screen) as I tried to repro it by using the torch app again and it doesn't make a dent in the power. No games or web browsing was happening.
I'm not so much looking for a solution as I am interested in posting this as a kind of bug report, since the ROM is in early alpha. If there's anything I can do to provide more information, I would be happy to do so.
yea. h8rift is working on these wakelocks. if you look at the time "awake" it is awake even when the screen is off. gps and nfc have been thought to be the culprits. but yea all of us are having the same issues.

I see that it was awake a lot, but it's the sudden spike toward zero that seemed really odd to me. I was using it at the time and it dropped so quickly that, by the time it told me to plug it in, it was already at zero.

yea i experienced the same thing, except from 82 percent to about 71. just overall the battery readings and management on cm10 so far are whack.

Battery drain from a non-running app?

Hi. Its been a few days since my Nexus 5 battery has been drained pretty fast. Lasts only about 4 hours after fully charged with little use. Since I recently started working in a really poor reception area I figured that was the problem, my phone constantly trying to find a signal, but when I go to the details, I see that Instagram is responsible for using up 40% and it wasnt even running!
Im no developer, or even experiencied android user, but, how is this possible?

Welcome to android and app permissions. It's accessing a number of things on your phone with location probably being the number one. Get something like xposed and app ops to tame what the app is allowed to access. You should also get gsam or BBS to get a closer look at what is using your batery.
This happened to me last night with a messaging app I used to replace hangouts. It dropped about 12% overnight with data and WiFi all off.
I looked in battery use and messaging sucked most if it up. I cleared data in the messaging app and that fixed it. Later today I switched back to hangouts until I download another messaging app. I don't trust that one now.

Thanks for your reply. I'm guessing I need root for Xposed and those other apps ? Like I said I'm just an ex iPhone user who just converted to Android. So haven't given myself the time to tweak around.

you dont need xposed. looks like instagram had a stuck process or was stuck syncing. a reboot usually fixes that. there are other ways to fix things, other than installing xposed(as xposed could bring in its own issues). there are many apps out there that help, greenify being one of them. also, there are a few great apps to help you stop wakelocks that are out of control.

Terrible idle battery drain!

I have a terrible battery drain when my phone is idle. Tried everything, but nothing solved it. Ever since Lollipop I have this issue.
Clean flashed MM and still nop. Flashed ElementalX 6.04 yesterday which still couldn't solve it. This is frustrating :crying::crying:
I have disabled everything too. No Wifi, data, bluetooth, location...etc (My phone is not a smart phone anymore)
Only adaptive brightness is enabled.
Yesterday I fully charged and went to sleep to find out it has drained 28% after a 7 hours sleep. Removed all the unpopular apps (suspicious apps) as well. BetterBatteryStatus says my phone has been in DEEP SLEEP throughout the whole time too.
Please give me a solution

How old is your phone?? You might need to replace the battery. Especially you've already done everything from kernel, to clean flash to disabling apps and settings
your bstats also tells no abnormality? how about its partial wakelocks? can you post those so we can check it out?

According to BBS my phone has been in deep sleep throughout the whole time. I'm assuming its the battery, I need to replace it may be.
I charged my phone again. I will post partial wakelocks too in few hours time.
Thanks alot
Even though it may not make a huge difference but you can try draining the battery out to 0 (until the phone can't stay on even after a force power on) and a full charge (30 mins to an hour overcharging after you see full battery indicator).. Gluck.
I replaced my battery, I was getting hard reboots as well. But wow with a new battery and marshmallow my nexus is like a new device.
99% no or unknown signal.
That could be the cause of your drain, when the phone has no signal or poor signal it will use a lot of battery to keep the connection alive. Set aeroplane mode on

App power consumption not being displayed

Hi all,
This is my first post so sorry if it's the wrong place or just plain stupid.
Under power management, the power consuming apps section displays "currently no apps to report" for both unused apps and consuming apps. Anyone else have this problem?
Any help would be greatly appreciated
Normal. That means you have no misbehaving apps consuming an abnormal amount of battery
Here's mine

I forgot to close my SSH client some weeks ago (with an active connection to my home router), and it was reported
Thanks for clearing that up. Only got my phone on Sunday just been trying to work out why the battery is going down quick. Used about 25% since 9 am this morning.

But under battery /screen how much time has the screen been on?
Sent from my Xperia z5 using Tapatalk
Well it's now 15:16 and I'm now on 39% total screen time 2:44.
This is with brightness at lower setting and no wifi only mobile 4g.
I've been using chrome a fair bit and Spotify
But Spotify doesn't seem to actually effect my battery much at all.
How does that compare to others?
Just want to know if it's normal.
Thanks again
Ignore me. It's chrome it's used 43% of my battery.
I guess thats the rma (radio mobile active) bug , try disabling mobile data and use wifi to see if there is a difference in battery drain

Could you plz tell me the name of the theme you are using? I think the navigation buttons are really beautiful. Thx
Guyz, m not using WiFi even for a minute but in battery stats it's always on, and i think it's eating my battery faster.
Any solution or anyone else facing it?

Phone Gets Warm (even hot) in Pocket!?

Hello all! Recently got my Verizon Pixel and every time I put it in my pocket or use it, it randomly starts to warm up and gets uncomfortably hot. Is this supposed to be happening? Let me know what you guys think, thanks!

What apps do you have running, have you checked your battery stats and see what's running that could be causing this? Do you perhaps have a bad signal in your area?

I do not believe that it is any one app or background process causing this since the battery stats say that the Android system is what mostly drains the battery (along with the screen). In terms of signal, I do have somewhat weak connection here and there at the University. However when I go off campus, it also begins to get quite warm in the pocket.
I have quite the opposite. In fact, I've been crazy impressed with the lack of warmth during intense operations.

I've been having that same issue. I have the smaller Pixel. Usually rebooting seems to fixed whatever it is. But it's still a little disconcerting.
I have had another model of a smartphone couple of years ago and there were the reports of this phone getting hot when it was in the pocket. It turned out to be some sort of a health app that was running and sensors were active measuring stuff. Few other users chimed in confirming the issue, but my phone(same model as theirs) didn't have that issue. It was because after getting the phone, I disable all the app that I am not interested in. I believe it was a Samsung model, possibly their Galaxy line.
