Have a Telstra S2 on stock carrier ROM
Experiencing random reboots sometimes even on idle.
Last night I ran stability test to check for RAM and actually the test ran for 5 hours before the battery ran out even though my device was fully charged the beginning and connected to the wall charger
However the device got to 61 degrees temperature!
I emailed the dev and he said its a concern the device is getting that hot and that also that the battery is draining that quickly that it can't keep to keep device charged.
Suggests I should RMA it. What do you guys think?
You stressed the device to it's maximum extent and it ran for 5 hours, so 61°C is VERY NORMAL IMO. No question of RMA and else. And also that is the temperature of the Battery, if that were of CPU I'd like it too
Regards.

Yeah ok that seems fair enough but still I am troubled by these random reboots which I still think I am going to need to RMA for? Shouldn't be happening should they?
Still has the huge battery drain though even when not running the stability test
After you have had the battery drain for a few hours, post up a screenshot of the battery usage page.

Ok so Here's the deal
When I flash a rom I charge the phone till it hits 100%. I then reset the battery stats and go on about my day. With in a few minutes of being off the charger my battery has now dropped down to about 96 %. I do realize that batteries do not stay at 100% but this is crazy. I've only deep cycled my battery once for fear that it may damage my battery.
I Am using Teamwhiskeys ultra awesome bionix-v rom with ttabals oc kernal. I know I am to expect a slightly more rapid drain but this is crazy. I have even tried to lower the vcore and I slowed down the cpu to 800mhz. It still drains just as fast.
The odd thing to me is If i turn my phone off and let it fully charge to 100 percent reset stats then turn on phone It will show full for a minute then drop down to to 96 or 95 percent.
I personally think my battery is damaged but spare parts shows that it is ok.
So i am rather confused by this .
I know I should probably use the stock kernal but it seems like its just as bad with that.
I have looked at the threads about battery life and I am not expecting it to be amazing just hoping it will be ok!
Tell me what ya think !
mt battery play tricks on me too when my phone doesent see that im lookin at it it shows 90 when i look at it and phone notice it bounces to 85 like it hates me , lol but dont take my words for it P
Spare parts would show that too. I remember when I had my G1 spare parts would tell me it was fine. But a 3 hour full battery doesn't seem fine does it? Id suggest getting it replaced.

Ill probably nurse it... but I am having major ocd type problems about it.
I cannot stress this part enough, so I'm putting at the top, do not do the following often, as it can have a negative effect on Li batteries if done too much.
You want to try what is known as a bump charge. With your phone off, charge to 100 percent. You will see the green battery icon with "100" on it once it reaches full. Unplug from the charger for a minute, then plug it back in, phone still off, and let it reach 100 again. If you want you can do this a third time, do keep in mind, bump charging too much or with any type of frequency can have negative effects on your battery, but doing it once in a great great while helps with with what you are experiencing.
thanks Br1cK'd and those who replied.
I have tried the bump charging method. I am affraid that my efforts to repair my battery are causing it more harm than good.
ok i just restored bionix v and had it charge to 100 percent
spare parts says
battery level 100
battery scale 100
battery health good
battery voltage says 4243mv
battery temp 30.0

There is one thing you are messing up. If you flash your phone on a 100% charge then you DO NOT need to wipe battery stats. You only have to wipe battery stats if you flash when your battery is not at 100%!

It's not out of the ordinary for a battery indicator to show a few percent drop rather quickly on a LiIon battery. Secondly you should take a battery indicator with a rather large grain of salt. Expecting precision in single digit percentages from the indicator is unrealistic and nearly impossible to rely on given the nature of discharge of a battery. Batteries do not charge or discharge in a linear manner, and people do not use battery powered devices in a linear way either.
It is a visual guide, not a precise and accurate indicator. Many custom roms have a percent accurate indicator, but don't mistake this with being dead-on accurate. It is merely an attempt to make it a BETTER visual GUIDE.
To evaluate battery life properly is moderately time consuming, though rather obvious. Use your device as you would normally. Pay attention to how long it stays charged. If it's not staying alive for a reasonable amount of time (12-24 hours depending on what you are doing of course), then it's time to dig deeper. Apps that wake up and generate unnecessary Partial Wake usage, a lot of background application syncing or apps with short sync intervals, being in an area with poor data/voice signal....these are the usual culprits.
Apart from situations where people are playing around with experimental kernels (i9000 derived kernels tend to vampirically drain battery a few percent an hour regardless), the things that drain your battery are....things that "use" your phone. The more you do (and the more your phone is doing with your permission while it's in your pocket) the less battery you will have.
In the end it comes down to asking yourself some questions. Do you need to automatically update facebook, myspace, twitter feeds constantly when you can manually update them and be inconvenienced by a 10-20 second wait? Do you really need to update 35 rss feeds in Google Reader?
Most people's power related issues come down to three things.
1). Apps that wake up without your knowledge and waste battery for no good reason (I'm looking at you Media Hub!!)
2).All those other apps and widgets that are updating inside your pocket when your not reading, watching, or caring about them.
3). Being in an area with poor data/voice signal, forcing your phone to "hunt" excessively for a better connection.
Apps that wake up and do god knows what without your knowledge can either be removed, disabled, or frozen. Examining partial wake usage can give you insight into what may be going on in that scenario. Apps can be "Frozen" with Titanium Backup Pro (paid) or App Freezer (free).
The other part that is within your control are all the apps/widgets you actively use, and your decisions about how often (or even if) they update themselves.
couple weeks ago, i pulled my battery out when it was at 81% started it back right away and it was 45%, did it again today, it went from 71% down to 29%, my battery reading is tripping, I noticed. MY BATTERY IS HORRID, i lose 1% power per min on the lowest screen brightness display setting, could this have anything to do with this?
side note:
using my battery. battery stats says that my screen is causing 99% drainage.
my buddy battery: my screen is 80% drainage.
bad battery??? it still drains really quick with my buddy's battery, but DOES perform better. but not by much...
another thing, lol..... charging differs. sometimes it can charge like 10% every 10 minutes, and sometimes 30min for 10%.....its just weird. and my phone doesn't last me longer than 10 hours full charge, minimal use.
You may want to look at your battery health under the battery information menu.
Also to better understand and provide support we need to knock out a few things.
What is your current set up? ( rom,kernel, etc)
Have you done a battery calibration at all?
Have you run things like cpu spy to see what apps could be at fault?
All of this can give the community a better picture of what may be going on
Also I pull my battery alot because of testing and sleeps of death and I see very good battery life still. Atm 15 hours @ 72% and I am far from conservative.

kernel is the community TSM, battery still was wierd in stock rom, sc 2.9.2, and others.
battery health is good according to spare parts at 3850mv.
currently charging its been at 16% for 10 mins.....

Just FYI, you don't have to do a battery pull when you get SOD. Just hold the volume up and power buttons until you see the samsung logo, then let go. This is a hard reboot of your phone. That will save you battery a little bit as you won't be pulling it as much.

Suspect RAM problems due to random reboots so I wanted to run a RAM test
Last night battery was on 100% but still plugged it in to wall charger
Kicked off Stability Test and went to sleep
Woke up this morning to find it ran for 5 hours 7 minutes before the phone shut down due to a drained battery!
So running stability test was draining the battery quicker than it could recharge! Of course the screen is on 100% of the time time because it says not to run the the stability test app in background or while on standby but should this happen?? Should it drain that much??
Will try again tonight with everything turned off and see if I can get the test to run longer..
The phone is able to drain more power than it gets through the charger, yes.

Thanks yeah well I have just tested it again and yeah battery was at 96% but most services still running on the phone so I kicked off the stability test for 10 minutes and noticed the phone dropped to 92%!
So I then turned off wifi, bluetooth, sycing and screen brightness and ran again. Battery was at 96% ran for 10 minutes battery remained at 96% afterwards so it was keeping up.
I thought I could further optimise it so I turned data off, cleared the ram and closed all running applications and tried again. This time battery dipped down to 88% after 10 minutes.. wtf!! I guess it's true about you shouldnt force close apps that are idle, let android handle them itself, also is it maybe because data was turned off some widgets or apps might be doing a constant connection retry and it keeps timing out? I can't explain why it would drop like 8% when I turned off a lot more stuff..
You do know that StabilityTest is supposed to stress your CPU 100% and by doing that it uses up pretty much maximum amount of power? No realistic app uses up that much power. It's useless to run StabilityTest for longer than 30 minutes tops, if you are overclocking (I guess that's why you're testing) I find 15 minutes stable is good enough for 99.9% stability in real life apps and daily use.

Hmm well I was running the test to check my ram because I've had a few random reboots. The instructions for the app say most problems can show themselves within 15 minutes of testing but it said sometimes it took close to 5 hours for the reboot to occur revealing the ram was dodgy so this is what I was trying to achieve by running it overnight
Sorry to ask a probably popular question but search on the XDA app is very meh.
Phone idle will always be the top battery killer for the average user. That's just because the phone is isle more than awake most of the time.
You can get an app like setcpu and have a custom profile to underclock your cpu while you're not using your phone though

What do you call murdering?
Is your battery dead in 2 hours, or do you see idle as the top user after 12 hours with 70% left?
Why don't you charge the phone while on. When 100%I turn it off. (Don't unplug power in this whole process ) then pull battery. In a couple seconds you will see a battery with a ? In it. Then place the battery back in. It should say 5%. Let it sit for 3-4 hours. Boot to recovery and while battery status. If no recovery, boot to os and wipe battery status. Then phone idle ( the phone only shows "phone idle" to give you will a total of 100% since before your battery once had about 60% of normal battery life. Now that you have alot Battery, phone idle is a much smaller % than you had before.
Not murdering but in a 2hr space 50+% of my battery is eaten up due to Phone Idle.
I'll try that fully charge trick tomorrow. Thanks.

Before I did that I had ..... 4 hour talk time max. Now im 6+hrs. You'll see. Thank me later
Put your battery in the witness protection program. But seriously if in 2 hours ~50% is gone, I don't think its phone idle. Also something to consider is terrible reception eats battery. And 4g even though its not true 4g those higher speeds come at a cost. I think you can guess what the cost is.
I voided my warranty.

Even if I heavy grind on the phone until its dead.. it will not have a whole lot of battery left, nor will idle consume so much of his battery. So he needs to try the basics of battery maintenance first.
Sorry guys I described that horribly.
I mean of OVERALL drain 50% is Phone Idle. Not 50% battery life.

well now that you describe it like that, use the search and read up on the many threads about phone idle. peeps can't seem to wrap their head around it. and read up on display time too.
Phone Idle should be the remainder of everything else draining your battery, basically the minimum power draw. If you add everything up you should end up with about 100%. I say "about" because android rounds the numbers up/down to whole numbers.
If your phone idle is at 50% you're doing bugger-all with your phone. So long as your actual battery life is normal then there's nothing wrong. If your battery life sucks, then possibly your battery is dead/dying or something like the minimum CPU frequency is set higher than normal causing a constantly higher power drain.
Well as long as he followed the steps. Phone idle will not take such a high % of battery usage on the battery manager. If he talked on the phone for an hour and did pandora for an hour. You would see idle would take a small % vs the talk time and pandora streaming combined/separate.
Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
