Overheating [MTK6592] - Android Q&A, Help & Troubleshooting

So, I was using my phone, watching youtube, everything felt normal, except my fingerprint sensor stopped working suddenly, when I reached for the fingerprint sensor (above the battery), I backed off, it "burnt" my finger. 60 degrees (Celsius) at the very minimum. I immediately felt the battery, but it wasn't hot at all. A bit warm, nothing special. If you check a picture of my phone (elephone p3000s), you can see a metal circle with the camera and the fingerprint sensor on the back. The bottom of that circle was extremely hot, and yes, it's really made of metal. My fingerprint sensor stopped working (not surprisingly, since it overheated by this much). As for the performance, it was buttery smooth, as usual. Battery consumption didn't seem to change much. I took the battery out, and the phone started cooling down. I put the battery back in, but didn't turn the phone on. Nothing changed. It remained cold. I tried turning it on again. In less than 10 seconds, it overheated to the same very hot temperature (and Android was still booting, it takes about 2 minutes to turn on). So, what did I do to cause this? Nothing! No new/updated apps, no heavy usage (just youtube in 720/480p), no physical shock/damage, so on.

[Q] Quirky battery issue after phone refused to boot

last night i had my tbolt charging. the phone was off while charging, and it was left plugged in for a few hours beyond the led changing over to green.
after i unplugged the phone and went to turn it on, well... it wouldn't turn on. i did feel the initial vibrate i always get right before the htc screen comes on, however, the screen never came on. i ended up having to pop the battery out and then after putting it back in the phone booted normally.
however, now it seems as though my battery is draining way faster than it has been. i've had the phone a few weeks and the battery has been properly conditioned. after taking it off the charger at approx 2:00am this morning, a mere 10 hours later (whilst completely in standby for the entire time) it's already down to 83%.
what gives? could this just be an accuracy issue with the reported levels? i've read about fully charging and booting in to recovery to reset battery stats. or is it a far worse issue and something has happened to my phone that's damaged the battery in some way?
btw, i'm rooted and running das bamf remix 1.7 with imoseyon's leankernel (running in normal mode with swap enabled).
just a quick update:
after some moderate use (texting, web browsing, downloaded a few market apps) the battery continues to drop much faster than it ever did before. i'm using wifi at the moment.
Have you cleared battery stats lately?
Sent from my ADR6400L using XDA App
no, but i'm going to do just that tomorrow after work when i have a chance to fully charge the phone.
one other thing i just realized that may be contributing to the problem though... my g/f was playing around with my phone and she signed into latitude. doh!

[Q] How much battery does your display use (1%/min)

Are you guys seeing a 1% drop a minute when you are using your phone?
I'm experiencing sudden drain after the update as well and I've tried everything from freezing VZ location to factory restores without any success. It seems the majority of drain is the result of the display.. Here's what I did to try and determine that.
Turned on airplane mode
Lowered display to the lowest setting possible
Set the screen timeout to 10 mins and left the screen on
On average my phone was losing 1% of battery a minute and the same was true when I disabled airplane mode. If the display on the phone was shutoff I was averaging about 1% an hr (in airplane mode) so I'm thinking this is related to the display.
Are you guys seeing a 1% drop a minute when you are using your phone? Any help would be greatly appreciated.

Are you talking streaming, idling, phone calls, data ? guess you need to define use a little bit. Even prior to the OTA , on stock battery while surfing the internet my phone I would drop almost that fast. I bought the extended battery and it was much better. After the OTA, I got an otterbox case and went back to stock battery and it still drains fast while surfing internet, but Idling or sitting in my pocket no drain.
Doing nothing at all. I just changed the screen timeout to 10 mins and left the screen on sitting at my desk, doing nothing. I was in airplane mode so no streaming or anything was taking place... If I turn the screen off I have very minimal drain.
I'm just trying to gauge whether or not having the screen on (doing nothing) and draining 1% a minute is realistic. At this rate my battery would only last a little under 2hrs.. I might believe that if I were streaming movies, phone was on, 3/4G on, etc. but in airplane mode none of that was happening.

This looks like it's a specific problem to your phone. I've never had that jurastic of a battery drain on my Rezound, even while surfing the web, playing games, listening to music, etc. If I were you I'd go to the VZW store and talk to one of the Verizon reps about it. Hope I helped!

It is the same for me. My screen destroys the battery. It can idle forever... but it does drop maybe 0.5-0.75%/minute for me.
I'm going to have to get an extended battery sooner than later. Screen destroys my battery. Just texting and a little bit of the XDA app and my battery will go from 95% to 20% in like 4 hours.
My phone currently has had the screen on for an hour total this charge. 15 hours on battery, 43% battery left. Screen used 38% battery having been on for an hour.

Definitely not a 1% drain per minute here. I was using netflix while riding the train to work(auto brightness) and dropped about 10% in 20 minutes.
The more shocking part is that I plugged in my newtrent external battery charger and still dropped 4% over 30 minutes(obviously much preferrable to 10%+ but when charging you would think you'd break even at least).
Yeah my screen takes up a great % of my battery life too, watching videos on youtube and using Navigation kills my phone pretty fast.
Thanks for the feedback.. New Phone
All,
Thanks for the feedback.. I went by VZW and got a replacement phone which is currently working out much better.
Thanks again!

how hot is to hot? phone heating issues

ok so i noticed ever since i got it my s3 gets very hot with little usage...its only very hot usually at the bottom by the homebutton and when the phone is charging the whole phone gets hot...the battery has been upwards of 120.9 degrees while charging...i'm using the factory charger and phone is stock...nothing really added on, not even many apps...ive even tried a non factory battery with the same results...does those temps sound normal? i'm wondering if it's the phone....
one question....Wi-Fi on during sleep switch to "Never"?
nope...it's set on only when plugged in...should i keep it on never?

[Q] How do I force my phone to ignore (faulty) low attery level?

I know for a fact that my battery level is incorrect. It's a 2500mAh battery, and yet after a couple minutes of heavy use, the battery level will drop to zero and the device will shut itself off.
Weirdly enough, I have this same issue with my MacBook, and I've figured out (at least on the MacBook) what the problem is: the machine isn't calculating the remaining time/percent correctly. If I don't use it to do power-instensive tasks, it will be fine up until the battery truly drains. But if I run, say, high-graphics video games, it will detect the battery's getting used very quickly, somewhere along the line it will freak out thinking that this battery drain is leaving it with seconds to spare, and will shut down. If I press the power button to start up, it won't, only displaying the 'out of battery' symbol on the screen. But, in actuality, there's usually about 30-50% battery left in there. How do I know? If I apply the charger for a bit, even for two seconds and then detaching, forcing the machine to recalculate the remaining battery, it will turn back on and have 30-50% left for me to use.
Here's the thing, though: with my phone, I usually don't have anywhere to charge it. So I'll unplug it in the morning to last me all day, hop on a bus to explore the city, forget about this issue and launch a graphics-intensive game, and then only realise what I've done four or five minutes later when it shuts down on me, thinking the battery's completely depleted.
So here's my question: How can I force the phone to ignore the battery level, and keep sucking juice from it whilst there's juice to be had? I know, I know, it shuts down for my own good, to make sure it has enough battery so that it can power back on again later. But right now, this usually-useful feature is rendering my phone virtually useless. Any advice?
Thanks.

Replaced Screen and battery draining fast.

Hi,
I dropped my mobile a few times and the screen cracked. It was working fine until, one day it started acting weird. Ghost touches on screen. So i got my Touch screen and LCD replaced at a local mobile store. After this, i started to experience very high battery drain. Phone gets switched off around 20% battery. I changed my ROM to see if it was rom related. But the same thing happens. Even on standby, the battery drain is high. It dropped around 20% in two hours with very light use. I think the new panel is the reason for this problem. Is there a chance for this new lcd to affect the battery? Can someone help me.
