Today my phones brightness was turned down by itself. So I went into the settings to turn it back up to 100% and there was a message under it saying my phones brightness was reduced to prevent overheating. When I changed it backed to 100% it would bounce back to about 50%. My phone was kind of hot because I was using it while on the charger. After it cooled down it let me change it back to 100%. I thought I would share because I found it interesting.
this actually happened to me the other day i was inside my car it was pretty hot day....
i think it does it whenever the phone overheat to stop any further damage
cool! i didn't even know such safety feature was build in
nice!

When at the Chicago Blackhawks rally (outside, hot day), my phone apparently shutdown while in my pocket. I reached for it to take a photo, and realized that I could not turn the phone on. I immediately figured that I had activated some resource hogging app while in my pocket, but it seemed unlikely as the battery was mostly full last time I had looked at it. After fiddling with it for a bit, I decided to take the battery out and try to turn it back on. This worked, and the phone rebooted with almost 70% battery life left.
I ended up giving this phone to my wife as she wanted a white phone, and I went and got a red version. Yesterday, the same thing happened to the white phone again. The phone was in my wifes (black) purse, in the sun, while she was in the pool. She was unable to charge the phone or turn it on until she removed the battery.
I can only think that heat is a factor here. Has anyone else had this issue? Is this a "feature" to keep the phone from over heating? Possibly a defect? Unlike an iPhone, the MyTouch doesn't say anything about it shutting down from overheating when it reboots.
Also, I've never had a phone shut down from these relatively mild heat conditions. If it is heat related, this phone is rather temperamental in regards to over heating...
Thanks,
Danny
I has to be a defective device i work in the sun all day few days in over 95 degrees and listen to music at the same time. Never had that problem

Ok so not sure what to do, mostly due to lack of time and patience..
I let my phone die today and when i plugged it in it had the orange led..i let it sit and it changed to an orange and green flash in the led..
i turned it on and the phone was powering but not holding a charge..
How long was it dead before attempting recharge? Did you attempt to use it with this low level of charge before recharging? You may have killed the battery.
it was dead for like 30 sec..the charging light doesnt glow anymore..it just flashes sometimes..
It sounds like the phone allowed the battery to discharge too far, which is a bit disconcerting. Do you have another battery to try?

My wifes phones from what it sounds like did the same thing. only the orange led light shows up while plugged in. Took it to the store and they did not have a phone to replace it with, so are ordering a new phone which will not get here till Thursday. The sales rep let my wife borrow her personal spare phone which is a feature phone...They said it wont effect the data plan... i am nervous and dont trust that we will be able to get the data plan back on the new DINC2 when it gets here on Thursday.
This situation sucks...
I personally have had that weird flashing aswell... although under different circumstances. I was downloading some torrent and saw that the battery was getting low so I plugged it in to my car and about 10min later it started doing that flashing. When I grabbed it the back felt incredibly hot so I disconnected it and turned the phone off. Then I removed the battery and it felt like it was going to burn my hand so I set it down and let it cool off. Afterwards, I put it back in and it was ok again.

It's possible you were putting some very high demands on the device, and did not lighten the load when you plugged it in, asking it to charge an already warm battery. Then again, something in the battery could have shorted.
Where to begin....my phone would last about 9hr before this issues started happening. For some odd reason my indicator LED light won't shut off I had to download an app to turn it off. When I try to turn of the phone It will automatically turn on again but before it does it goes to the charging screen even thought the phone is not plug to an outlet. It all started happening after I used my friends LG charger i'm thinking maybe I damage something.

Judging by the screenies it looks like the battery is to blame. Those spikes are definetly not normal.

Definitely not normal. Get BetterBatteryStats and see if you have a wakelock

Looks like the phone isn't correctly reading the battery.
However, the symptom of the phone going into charging when off when it's not plugged in (phone thinking it's charging) is pretty common with the Samsung Replenish, and is almost always an indicator of a bad charging port. This could also explain the LED not going out (ie charging). We see it in our store alot. Your battery dying in 3 hours would make sense, as the phone isn't charging the battery correctly in this scenario.

I agree.. it seems to be the charging port on the phone. My wife's phone had a very similar problem. Her screen would turn on by itself, the led light would stay on all day, and battery only lasted about 2 hours. It would always freeze up too once in a while and when you turn it back on, the battery drained like 20% in a span of 5 mins. Her battery stats look very similar to yours, with all the spikes. On top of that, her phone kept going into driving mode or voice talk randomly. Her phone was rooted with the auto root procedure. I wanted to back up her phone with TiB regularly and put on adblock.. but otherwise everything was stock on her phone.
What I ended up doing was a factory reset. That cleared up the freezing issue and the screen turning on and off, but the battery stuff was still acting the same. I did a battery pull over night and cleaned the contacts of the charging port of the phone with a very small q-tip and toothpick. I also cleaned the battery terminals as well for good measure. Put the battery back on the phone and charged to full while the phone was off. First thing I did when I turned on the phone was to download the battery calibrator app and run the calibration. Her phone has been back to normal now for almost 3 weeks.

Are you in a damp/humid area? I know my phone did that sometimes too during humid summer days. It's completely fine in any other condition though, especially during this colder winter.

i'm not in a damp/humid area, my wife and I have the same phone. Mine has been okay with minimal issues. Although now that I think about it, she did spill some water on the table with her phone near by a week before her phone start acting up. She had a TPU case which protected it from most of the water, but maybe some of it got in through the headphone jack or charging port??
to the OP: maybe you can try this battery calibration method as well. Some people have reported success with this: http://forum.xda-developers.com/showthread.php?t=1312273
So this morning when my alarms went off, me being myself slept thought them and they kept on going as usual.
The only unusual thing about it was my phone got ULTRA hot. The whole front of it, battery and the back where the processor is.
It got so hot I panicked and pulled the battery and let it cool.
What could cause this? There was no major battery drain for the alarms going off for an hour.
Its still working as normal. Just freaked me out a bit.
Your alarm was going off for an hour? Dang. Hopefully you werent late for anything. lol
The battery gets hot when its constantly doing something and the screen is on. Its normal. I mean, it COULD potentially ruin your phone over time. But electronics get hot. Theres not much you can do about it. I sometimes download files that take 3 to 5 minutes and while its doing that, my phone heats up how you described yours.

Phone always gets really hot when processor is being heavily used especially gaming.
Unless you see some sort of lag while it's hot I wouldn't really worry too much.
I also thought it was a problem, but when you know to hold in your hand without burning it's alright
I'm having a problem when I turn my car on in the morning. The device boots from start instead of just waking up from stand by. After that, waking up works just fine through the rest of the day. I thought the problem could be a faulty car battery so I put in a new one. It didn't make a change.
It's PX3 chipset.
Does anyone know if the device itself has some kind of battery or capacitor built-in? Or how the sleep mode actually works?
So, it seems it's got something to do with outside temperature. Last night was relatively warm (4°C) and in the morning the device just woke up from sleep upon turning the car on. When the temperature falls below freezing during the night the device starts from cold boot.
