another battery thing to try

found this on another site don't know if it has any relevance since i just tried it but will keep you posted:
Disclaimer: the following may *not* to the HTC EVO! And yes, of course we should NEVER have to deal with this kind of kluge. But it might help…
There’s a known bug in the cell radio software on at least one other HTC Android phone (Eris) that can significantly reduce battery life. Basically, it thinks it doesn’t have a signal (though it’s connected) and frequently keeps trying to connect, which steadily drains the battery, even when the phone is apparently idle.
To check if this is affecting your phone:
From the home screen, press Menu, Settings.
Scroll down to the bottom and press About Phone.
Press Battery
Press Battery Use
Press Cell Standby.
Take a look at Time Without Signal. If it’s 0% or a bit higher, then your phone is not affected and you can stop reading. If it’s 50% or significantly higher than you know it should be (e.g. you were in cell range all or most of the time), then the phone is being affected by this problem. BTW, Time Without Signal may not be displayed in some circumstances – try again later. AFAIK, all HTC Eris’s are affected, not sure about other phones.
The good news is that there’s a simple way to fix it (usually called the Airplane Mode trick):
Power your phone off and then restart it.
Once it’s fully booted, plug in the charger.
From the Home screen, press Menu, Settings and Wireless & Networks.
Press Airplane Mode and wait until it’s checked and back to full brightness.
Unplug the charger.
Press Airplane mode and make sure that it’s unchecked.
That’s it!

Will this fix cut down down on searching for a cell signal? Can anyone verify thi works?

Trying this now. Will report back in a few hours.

It doesn't make any sense, but I think this might have worked. I tried this about 4 hours ago and I'm still at 0%. I was getting as much as 50% without service. I'll report back again after I have some more time to test it.

I'm at 10 hours now and it's still at 0%. I don't know why this works, but it appears to actually work. I was even able to turn on always on data with no negative battery consumption since I don't really have much auto-syncing.
Thank you very much OP.

Same here, went from 4:00pm yesterday to 5:00am this morning and still had 50% battery. Watched some trailers, used a flashlight app ( alot, thanks to being without power till this morning), did some texting, and was watching weather radar. My time without a signal is staying at 0% also.
Thanks also.

Here's an easier way to do this from a previous post. FYI - I did this a few days ago. Here's my current battery test stats (I'm letting it drain itself out and see how long I can go).
Uptime: 32 Hours, 45 Minutes
Awake Time: 4 Hours, 30 Minutes
It has not been on a charger since it was last fully charged. Love it.

Wow, my stand by was at 58%, though I am inside a building with horrible reception, I sure hope this fixes it.

Will this fix be permanent or will I have to do this every time I plug the phone back in or after reboot?

The original thread stated it had to be done every time, but mine has stuck since I changed it using the method here: http://forum.xda-developers.com/showthread.php?t=700601&highlight=battery.
One other thing to note: If you download the app in the Market called "Network", you can access the screen to change it without having to do the dialing or airplane mode thing. This would be the easiest way to do it if you happen to have to do it every time you reboot.
Final stats:
Uptime: 35:15
Awake Time: 5:15
This is about twice as good as I was getting before.

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up

nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.

interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model

yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.

it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.

Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.

Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm

This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting

I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.

Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.

Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....

i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running

OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.

«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.

Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.

Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?

Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.

I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Has this ever happened to you?...Vibrant seems dead, battey re-install needed!

Since I have got it (2 weeks ago) i have picked up my phone make a call, and on about 7-8 occasions, have noticed that the phone is turned off, and I can't get it to turn on. The only solution is to take out the battery and put it back in. Has anyone else experienced this. I have updated to JH2 firmware, but it still happens. I even got a new battery for the phone (Bell employee let me swap with another phone that was going back to samsung for gps issues), but the problem still happens once in awhile (like every 2 days, sometimes more sometimes less). Anyone have any ideas? thanks
UPDATE: Someone mentioned for me to call my phone the next time this happens to see if it rings. They said it might stuck in sleep mode? Not sure, i just pullthe battery and then it works

I've had this happen, but only when the GPS was on. If it's happening with the GPS off, I'm guessing you've got a lemon.
So far I've not needed to take the battery out, though. I've always been able to reboot by holding the power button down for 5-10 seconds instead.

Yes I have been experiencing the same problem. From what I can see, it seems like the phone is over heating then it locks up. My only fix was to install a battery temperature monitor and also kill any tasks that are not needed by the phone. My phone hasn't locked like that since I've been doing that.

I have not had this problem. Been on a call for about 1-2 hours one time and the phone was fine. I was able to switch it to speaker, bluetooth, open other apps, and etc without any problems. I don't run task managers. I do have one, but I rarely use it.

Interesting...I experienced this for the first time today. Picked up my phone from teh night stand after having it plugged in all night and it was off. Had to pull the battery to get it to come on. The battery was about 85% charged when it came back on. It worked ok since but the battery drained kinda quick. I am using an aftermarket battery, got the 2 batts and charger on ebay. So I put the other battery in and havn't had any issues. I wonder if it over heated while charging? What apps are you guys running? The one I am running that would be most suspect would be weatherbug elite, and I just installed it a day or 2 before this happened.

I think it is a GPS issue. I got this phone on the first day of release. I’ve never had this problem until just days ago. I hadn't used the GPS extensively before last Thursday and Friday. During my business trip I had the GPS on for almost two days straight and during these two days I experienced the blank screen, shut down twice. I had to cycle the battery to get it to boot.

I had this happen to me while using Set CPU. Check out this thread. http :// forum.xda-developers.com/showthread.php?t=727006
take out spaces and what not.

I had this problem on my g1 but it started to get worst an I soon need too keep my mobile always connected to a charger so out turned into a landline phone lol but it was because I somehow broke a middle cell in my battery and need replacing but I don't know what to say about yours cause you tried a different battery :S

Experienced a freeze just a few hours ago while running the navigate application.
Trying to show my wife how uber cool it was and all. Switched on GPS, launched maps, chose directions, method / navigate. GPS locked and had my location pinned down until I reached the corner and suddenly the GPS kicked me to a location about 5 blocks away then froze the phone, requiring a battery pull and reboot.

Bizarre battery usage behaviour

My Galaxy Note has been performing beautifully since I got it back in January. I typically get several days out of a battery charge - I'm a pretty light user. Two days ago I powered it off for a couple of hours. After turning it back on I made one short call, then nothing the rest of the day. I think it was indicating about 50% power remaining when it was powered off. That night, I was surprised to see it way down at 15%, so I charged it back up to 100%. I did note that I had left the Messaging application running, but that's all - no wifi, bluetooth or anything like that. Next day I was astounded to see that charge last only about 4 hours (according to the meter). Not only that, but the phone actually felt warm to the touch - something I've certainly never observed before. It was like it was running on amphetamines or something!
I was sufficiently alarmed by this to power it down again, remove and reinsert the battery, and power it up again. At that time it was charged up to about 75%. The weirdness continues - since then, about 10 hours ago, it has been almost locked on 75%. It may have made 1 or 2 calls in that time, but no other use at all. I do not have any of the power saving settings enabled, and I'm running Android 4.0.3.
So the question is - has anyone else seen any behaviour like this? Can it be just the battery monitoring getting out of sync? Can powering it down do that? It would not have bothered me too much if I hadn't felt the over-warm case. I find it hard to see how that could be caused by software, but it's a strange and murky world in there!

no updates installed of os.?
no new app recently installed?
Try andosensor and check battery level if its around the normal capacity when charging. Could be battery issue, could be a many things

I did update the OS, but that was a couple of months ago, long before this happened. I observed immediately after that update the battery usage seemed to get worse, but after a couple of discharge/recharge cycles, it got its act back together and has been fine since. That's why I was wondering about monitoring software getting out of whack this time - but couldn't see how software could make the case warm!
No new apps for at least a couple of weeks. I'll certainly have a look at Androsensor, thanks for the reply.

Your phone isn't going into deep sleep. Use an app called CPU spy to check this.
Mine usually recovers back into deep sleep after I reboot my phone.

Check for partial wakelocks. Otherwise, if you're complaining about battery percentage dropping when you reboot, that's because the battery monitor believes that the battery is not as charged as it really is due to high CPU load dropping the voltage.

[Q] Battery Stat/Graph Reset?

Yesterday I returned my N7 device because it won't turn on despite having around 80% on the battery the night before. I woke up in the morning to find that it won't boot anymore. I tried all methods like holding the sleep and volume down button for 30+ seconds, plugging it to the wall, and connecting to my laptop. I went back to the store to have it looked at, and since it has only been 10 days since I purchased it, they agreed to replace it with an available unit in their stock.
Now, with my new device, everything is well except that the battery gives inaccurate reading on the up time. The battery status/graph shows how long your device has been on battery, but fails to reset after charging. Suppose I have been using it for 22 hours, if you go to the battery details, it will show 22 hours of use, however, I believe that if you charge it, it will be set back to zero. In this case though, it continues from where it left off. Same with the screen time, it should be reset back to 0 after prolonged period of idle time, however, it continues from previous use.
Is there any way to fix this so I may get an accurate data on my battery activity? Thank you.

One way is to download an app called ROM toolbox and then go to ROM management>Management tab>Wipe options>Wipe battery stats.
I'm not sure if it requires root.

Thank you. I'm sure to try this out. Do you have any idea why it's acting up?

Well I can't really say since I haven't faced such a bug till now. But I think doing a hard reset fixes the issue because it's software related.(if the first method didn't work)

It depends on your charging behavior. If you unplug it at 85%, for instance, then it should not be reset. Same with screen time.

Ah yes, exactly. I charged it again to full all the way and it did reset the status monitoring. Thank you!
