For those with battery/lag issues

I noticed yesterday that my mt4g (stock, not rooted, with ota update) was warm and had dropped >10% battery in 30 minutes or so.
I loaded watchdog lite and didn't see any runaway processes or anything. However, my battery still seemed to be draining faster than usual and the phone seemed a bit laggy.
Today I was more curious so I fiddled with watchdogs settings and enabled monitoring phone processes. As soon as I.did this I got a notification about a process taking over 55% CPU. I opened up watchdog and saw that init process was using between 50-89% CPU.
I did a quick search of Google and xda and found some reports of similar issues with other android devices, namely this xda thread:
http://forum.xda-developers.com/showpost.php?p=8966211&postcount=1
I turned on usb debugging as recommended and init has yet to set off watchdog again today. Phone seems snappier and battery seems a bit better so far.
Just thought id share if any other mt4g users are experiencing mysterious battery usage/lag, its worth turning on usb debugging to see if it helps - can't hurt imo.

Hmm interesting. I've noticed that when I'm charging the touch screen gets a little unresponsive.

cool thanks for the info. i just did that for my phone so i will see if i noticed a difference in my battery life and performance

Hi Werk, glad to see my thread is helping you guys too..
Although it was my thread, thanks must go to Topcat who stumbled across this fix.
Im very confident that the /INIT process wont return, out of the 25 thousand + viewers only one has reported that the /INIT process has returned after restarting there phone, where a quick uncheck/check of USB Debugging has solved the issue again.
Personally I've not had the problem for sometime now and don't expect it to come back..
Regards Rick.

I've had that issue with all my android phones it seems - Cliq, N1, Vibrant, MT4G and a G2 I had for only 2-3 days.

I have always kept usb debugging on, my battery life is good. 36 hours now and I'm down to 28 %. Mostly standby though. Going to run it down for full charge.

Well, after a full run-down of the battery yesterday and a recharge overnight, I'm off the charger for 8.5hrs so far today with heavy browsing, email, and Logmein usage and battery is at 65%. Very, very happy I stumbled across rixsta's post and Topcat's information. This is like a totally different phone now.

Thanks for the info werk. Charging my empty battery and just turned on USB debugging. Let's see how my battery life goes. It barely last 12 hours for me.

You know what, I thought I was the only one that realized that lol. Mine does that too. Luckily I don't use it much when its needing charged but still.

turning off mobile networks seems to make my battery last a lot longer.

Thanks. I turned on debugging yesterday around 1030. Normally when I go to bed around 2300 my phone is on its last leg or dead and I don't even touch it unless I have to, so that I can plug it in on my night stand when I go to bed. Last night around 2200 it still had a lot more battery than it usually does at that time... probably 10-15% more.
Also, thanks for mentioning watchdog, I snagged it off the market. Great app. bye bye ATK!

I'm still trying to figure out why my battery on the MT4G is so poor. This is my 3rd Android phone in 2 years. I always have considered the battery life on my G1 and MT3G to be fantastic. I do the normal battery conditioning to begin with, phones are all setup fairly identical, and yet I can barely leave work at 430pm without having to run for my charger. Yesterday I turned on debugging (which was always turned on with the G1 and 3G) and it didn't work.

Even with set-cpu profiles setup my battery life Is not so great

Anyone have any updates on this issue that they would like to share?
I noticed that when I turn on usb debug, Windows 7 has trouble finding the drivers for the phone.

What do you guys consider "good" battery life? The phone lasts me through the day with moderate usage. I'm not on it 24/7 (because, you know, I have a life), but I do use it for texting, light browsing, Facebook, some games, music, etc, and I always have battery life to spare before going to bed. I charge my phone every night while I sleep. Are people expecting the phone to last several days without being charged?

Just because you have profiles setup doesn't mean a thing. It's what those settings are that make a difference.
I have been consistently getting 36 hours of moderate to heavy use from my MT4G. My screens have documented that.
See here for a good example.

Check here for mystery battery drain on the MT4G that I found:
http://forum.xda-developers.com/showthread.php?t=872839&page=3
My MT4G now last about 2 days on a single charge with normal use. Which is comparable to my old 2G iPhone.

[Q] Is yours getting warm?

My sensation is getting warm @ the bottom while using (normal tasks: messaging, mail).
It's not hot it's slightly warm. Anyone else having this issue?

Yes, although it doesn't seem as bad today as it was yesterday.

apparently if you turn off Wifi, you problems will disappear! Lol. Joke.

Mine has only gotten warm never full blown hot. Usually cools right back down. I figure it was just the dual-core working .

Mine gets a bit warm during moderate/heavy usage but I would say it's normal..

yeah, i was about to post.
Mine is very warm, as soon as i use it, it begins to heat, up to 109°f (43°C) when i use internet.
Using only mobo player, it's a stable 103°F (39.5 C)
it's very hot, i do not understand.
I stopped a lot of background sync, no difference...
any idea?
edit: btw, big battery consomption...

I would call for a replacement battery if it's that bad.
I haven't had any issues...though keep in mind I'm coming from a G2X that would burn my hand off.

My Sensation has been running very hot right out of the box. I have had it for a little more than 26 hours and it concerns me how hot it actuallly runs. Also just a few minutes ago I started getting a notice that the device had reset in an improper manner and asked if I wanted to report it to HTC. This has come up twice in the last 2 hours. I had the device setting on a table in a restaurant and thought i heard it do something now I know it was rebooting itself. The very high temps continue. I have a G2x and have not had all the issues other are reporting although it does get a little warm 96 degrees at times. I am at the point where I am going to take the Sensation back and wait for a short time and see if more kinks are worked out. The Sensation is a marvelous phone and will be almost untouchable if there are a few software updates to fix issues. Just do not want to wait like I have and did with the G2x and try to put up with overheating etc. I do really like the Sensation though.

[Q] HTC sensation Overheating issue

Hello I ve seen some threads concerning this issue already but I couldnt get clear idea of the allowed temp of the sensation, some people said anything above 40 is dangerous and should return the phone, some said above 50 and while other said above 60....I get around 34~37 on average and have seen 45 with GPS, web browsing, games..is this normal? and does putting the sensation in a case bad for overheating problem? I use the case mate..maybe it traps heat slowing down the cooling...

I don't know about the actual temperature but I do agree that something is wrong. Yesterday I was charging my phone in the car while using Nav and I had the screen set at full brightness. The phone got extremely hot and the screen automatically lowered it's brightness to the lowest setting. I'm not sure if the heat built up is coming from the backlight, or the battery or what. I was thinking about returning mine, but from the sounds of it they are all having this issue.
My build date is 6/2/11. Can anyone confirm if the newer builds still have this issue?

hmm the temperature has to do with the battery I am going to see if I could get my battery replaced and see if anything changes...

well from my experiences with battery that they do get warm when you are charging them, i have tested my phone when charging and it does get warm but playing games and everything else i dont feel anything that crazy.
which model are you taking about the 4G or non 4G??

Mine does not get hot from charging, it gets hot from playing games..that when my phone gets over 40...and my phone is T-mobile 4g

ive caught mr sensation getting as high as of 47 in a hot car hooked up to my car stereo playing Slacker Radio for 30 minutes. It burnt my hands holding it and one time i was wearing my thin shorts and i accidently left slacker radio on ( most used app ) and it actually left a red outline of the phone on my leg!

I noticed overheating issue specially whenever brightness set to higher. Even automatic mode heat is there. I wrote to HTC customer service, they replied, it's normal !!!

hopefully they can fix this.

From my experience all recent smartphones get hot charging them with the screen on for extended periods...mine also gets quite hot after a while but its not an issue as far as I'm concerned.

Haven't noticed any very hot issues with the Sensation since I bought it June 17th.

Overheating with LED cycling colors

Heya,
Last night I was playing Angry Birds in bed while plugged in a Kidigi dock. All is well. Now let me define some preconditions first.
The phone does get hot while:
1. Charging
2. Screen is on for a long time
3. Heavy CPU load
4. That goddamn hot weather isn't helping either
Right?
Put above conditions together. Temperature is 48.3C. I never thought I'd need to use a cooling fan on a phone, honestly. I did that to an overheating AMD desktop some time ago...
The thing is I knew there was something going on not by feeling the hot phone (remember the dock part?) but by seeing the LED strangely cycling through all three colors. Anyway I shutdown everything running, turned off the screen and kept my fingers crossed. The flashing stopped almost immediately as it dropped one degree in an instant. Took it 15 minutes to cool down to the normal 38C.
I looked around and didn't find a definitive answer for this one, even on HTC's site where they supposedly list notification color meanings. Therefore I now define a new one, let's call it "I'm just about to blow up now, k10xbye".
Has anyone else had such a drastic overheating case with this type of notification?
Sent from my HTC Sensation Z710e using XDA App

Nope. My phone hit 52 degrees. Nothing happened to it. Just turned the screen off and it cooled down

What was the third color? Mine only flashes orange for when its dying, solid for when its charging. Flashes green for notification, solid green when its fully charged.

Charging is orange.

I monitor my battery temperature by dialing *#*#4636#*#* which takes you into a section called testing, and then selecting battery information. This displays temperature along with other info. At one time, it actually said overheating. it has not happened again but if it does, I will seek a replacement unit. There is no way that any of this, your sceneraio or mine, is normal.

It's not normal. Heavier games with 3D don't do that. Max temp achieved was 42.

My EVO4G used to do that when I had it in the tank bag on my motorcycle listening to Pandora. The plastic cover would cause it to heat up and the led would cycle and it would stop charging and shut down.
There is a reason to this. The battery is mainly lithium. Lithium is highly reactive (read lots of very hot flames and sparks and excitement that you probably don't want going off near your girlfriend or dog or sensitive government documents). They use the same type batteries in RC aircraft, only lots bigger, and youtube will show some pretty spectacular lithium battery explosions, if you care to search them.
Imagine that going off in your pocket.
Ouch, a little....

Heh shutting down is reasonable, heating up till shutdown during normal use is not. And yes I watched those videos on YouTube when I got my wrist charger.

I m also suffering... But only gets hotter when u use the phone while charging, or use the phone for almost 20 mins continuously...

Here you go. 20 minutes Angry Birds, no charging, 43 degrees. Decided to quit. Anyway I've had enough for today plus not so pleasant on the hands.

[Q] Battery overheated. Single phone issue or major issue?

I received a samsung charge yesterday from Asurion (Insurance through vzw) and after installing the latest 12-11 release post ee4>ep4 ota and odin, while phone screen was turned off in my pocket, I noticed the phone starting to get a bit warm. Next i noticed it starting to get hot as hell.. pulled it out, and yes it was excessively hot. Pulled battery, allowed it all to cool down, water marks were clean, no bulging to the battery or burns to the device. I then put battery back in, and turned it on. Noticed battery went from the 38% it was at, down to 7%. Has this happened to anyone else or just me?
Thanks guys,
Drew

That's definitely not normal. I'd flash back to stock, see if it happens again, and if it does, exchange both battery and phone.

It could be a phone problem, but it sounds to me like there is (or was) something running in the background that was causing drain. Any app that grabs the GPS and doesn't let it go could potentially cause this. Facebook is an occasional offender for me.

are you using the official fb app? and I had gps turned on for a bit last night, but cant remember if it was on during this time. Since that happened, it has been off, along with wifi
EDIT: Asurion just called back and one of the ladies in the asurion client relations dept will be overnighting me a NIB charge. We will see what happens with this. Had nothing but problems with em so far, so I expect something to happen to the new one as well. We'll see though lol

Have you had an app cause overheating like that with the screen off? The only time I've had my phone get really hot was when I was oc'ed, with the screen on and sitting in the sun for an extended period while I was using navigation.

My phone heats up with the screen off if i have no service.

I am using the official app, though I haven't had the new one long enough to really make any observations of it. It was hit and miss. But, no, I can't say that I've seen temps like that, ever, except maybe once or twice when running in a car dock, in the windshield on a hot day.
