Now the phone is dead.
chronology is,
i charged my phone while turned off because i think this heating issue is because of its software. i didn't let it fully charge because i touched my phone and it was very hot. so i turned the phone on to see the temp. it reached 70C (attachment below).
So i manage to unplug and turn off the phone. Look at the screenshot, its 30% battery right? Well i turned off the phone and put the phone on the floor to make it cool. After that i put the phone in my desk. i was curious so i touch my phone again and it still heating while turned off. i woke up at morning and check the phone, now its cold but the battery drained. So i guess the cpu maybe still running at high clock even tho i turned it off. So i tried to charge the phone, but there is no sign of life, no led notification, i tried 20s power button w and w/o vol button too.
I have no idea, i think i got a new broken device, because when i unbox it, the phone was out of battery (my first time unboxing with uncharged battery lol)

Sad to heart that...
I think you bought a faulty device.From heating up,the processor died.Contact the seller.

It can be a battery issue ... it's better for you to not use your device until you see a xiaomi customer shop. Your device can explode at any time ... It's a serious problem !!!

Does your phone get hot charging USB?

Please, I'd like to see feedback from people on what circumstances people are seeing their phone get hot charging USB. If your phone gets hot on a USB charge, try powering down the phone completely and then charge on USB, does it still get hot?
And please, if your phone gets hot on USB charge, post how you're charging, your ROM, and how hot does it get? There are many applications for this. I use Battery Snap, you can use any program you like. If you don't have a program, please don't guess at the poll, but feel free to post results in a reply.
Also one would assume ambient temperature in the room is typical, but if yours is not (<20c, >28c) please post that information too.
Please answer the poll by the typical range of temperature your phone gets on a USB charge. I'd suggest charging around the 50-60% mark to get more consistent results.. For example charging if the phone is at 95% wouldn't be useful information etc..
One more slight constraint; if your phone gets hot "one time" but not other times, I'm inclined to think there was something else going on with the phone at that time. If your phone is consistently hot when charging USB then post results here.
Reserved in case I need to add any info..
I charged my phone off my Dell M6400's docking station today, started the charge after pulling the phone out of my horizontal case and the phone was 29.5C, I looked multiple times at the highest I saw it was 31.3, and most of the time 31.1. Using Battery Snap for the data. Started charge at 80%, as that's what charge it was from this morning until 4pm when I started I do not have USB Debug enabled by default on my phone, nor did I have mass storage.. When I got the mount prompt I just hit the back button.
Phone is about neutral to the touch, slightly cool. Normally when it's on my desk like this it's fairly cold to the touch, so I'll have to update later when I've put the phone in the same place without charging, but I'm guessing it's a few degrees warmer on the charger than off of it.
I'll repeat this a bit over the weekend here too as I have time, this time I'll set the phone sit on the desk for a while first, check temperature, then charge.
Please do post when you provide input on the poll so we know the circumstances... I mean, if your computer room is 35C and your phone gets 40C charging, I think that's reasonable My office here is around 24-25C.
Charged again today from about 75%, house is around 23C (wife likes it cold..meh) and the phone was 27C max charging on USB.
My AT&T Nexus One purchased June 2 from Google overheats and reboots.
Here's what I've found out:
I charge with the original AC Adapter and this only happens when I'm charging and the battery is LESS than 40%.
If the battery is 50% or higher, it's fine.
When the Battery is less than 45%ish, the phone gets hotter and hotter, from 33C up to 39.3C (is what I last see), then it will SHUTDOWN AND REBOOT. When it reboots, it would be about 37-38C. If it's still under 45%, temp will keep rising again, till 39.3% and REBOOT again, takes about 5-10 minutes for this to happen.
Weird thing is, if you pop the battery out and FEEL it, IT IS NOT HOT AT ALL. It's the DAMN phone that OVERHEATS.
2 nights ago, I was charging and reading in bed. IT DID THIS 3 TIMES IN A FREAKING ROW.
7AM EST, I called HTC, and doing a Device Swap.
Have not received my replacement unit yet. Funny thing is, HTC told me they send out device swaps of JUST THE PHONE, no battery no battery cover. So I have to keep my battery and battery cover. And I told them about my overheat/charging/battery issue, and they said if it still happens to mine, they can send me a new battery.
Anyways I will be testing the replacement unit with my battery and make sure it's VERY low to see if it overheats and reboots.
Other info: This happened in OFFICIAL STOCK FRF91. I'm currently running CyanogenMOD 6 RC1.

Hmm, yeah that sounds like hardware problems to me.. Curious, what are you using to measure? I'd assumed the battery temp stuff was really the battery, not .. something else?
In my case when my phone is cool, the whole phone is cool, not just blindly looking at numbers of course.
Again, would the folks voting really high temps try the things in my first post, and let us know what the ambient temperature of the room is, how hot the phone feels vs the measurement, what's being used to measure it... But particularly I'm curious if totally powering down the phone makes the problem go away.
Dial *#*#INFO#*#* then select Battery Information. It will tell you temperatures there. But I think the temps there is phone temp not batt temp, since in my case when it days 39.3C and I pull the batt, it feels less hot than the phone itself.
Also for my case, it does get hot and reboot while USB charging. Reported 3 time in a row again yesterday and I got pissed and HAD to turn the phone off.
Anyways, waiting for my replacement u from HTC.
Well got my replacement Nexus One today, serial number is higher than my 1 month old Nexus One.
I got it go to up to 39.8C and it did not shutdown and reboot, but stuff started crashing.
Music playing would stop, then if I try to start the song again or choose another one, Music app would Force Close.
Started Navigation app and that right away FC.
Anyone experiencing this?
I think you are using a goofy USB cable, or your room is HOT. Because the only time I've had my phone overheat, I was at a pool, in the sun. The phone's temp was 45 c also. I could still use it, but it was burning hot. An app notified me of the temp (I had it set that way) and I turned the phone off.

I'm using both the original AC adapter and usb cables from google.
Also AC has been on it's under 80F in the room.
The other day on the unit that keep rebooting, when I was navigating, i had to hold it up to the AC vent while i was driving to be able to use it... lol... sigh.
I usually only charge on ac but i think i can easily hit 37-39 while charging for over 30 minutes. Its has been up to 40.5 before i think but there were no crashes or anything. everything was stable (its hot but not enough to be seriously scared or anything)
the room at night is around 24? varies alot but the phone also sits on my bed and/or pillow/blanket. try not to cover it when i sleep.

Xperia Z battery behaving crazy, tough to charge it.

Hi everyone,
Since few days my Xperia Z battery is behaving crazily. It goes up and down. Sometimes when I disconnect the charger, like say at 60 percent, it suddenly goes up or goes down and when I again reconnect the charger it again goes back to 60 percent. Sometimes it doesn't charge only. Sometimes it starts charging, then all of a sudden it stops charging then starts by itself. :/
What's wrong with my device, I don't know. Need help.

Maybe you should try to charge it fully while it's off? Might not do anything but it might help You might just have a damaged/faulty battery.

Well, sometimes batteries just give out and start acting weird. How long have you had the phone? Sometimes as your battery ages, it just starts doing weird thing's. Wouldn't be a problem if we could change the battery

Give out within 7 months? Yeah, wouldn't have been a problem if we could change batteries. But that's the sad part of the story.
I am thinking of switching to Note 3 now. Charges fast, has a bigger battery, stays long. That's exactly what I need.
faster charging kills battery faster
Hi There, this may sound stupid but have you checked the lead/charger, is it an aftermarket one? I have also had similar probs but it was the conections. also try a system wipe and a full charge. and wait for the phone battery to fully flatten then repeat. always charge past 100 percent if you have installed a fresh rom or done a system wipe.

fast charging plus over charging or charging while using the phone= super kill battery

This is true, however sometimes the battery can indicate it is fully charged when it isn't, ( battery stats can be wrong ). I always leave my phone on charge when I sleep and have never had any probs my xperia t is now about 18 months old.
Thanks everyone. I guess I have somehow damaged the battery way too early. I used to use it while charging also. May be the reason of it's present Behaviour.
Right now I am not letting the battery go below 50% and have found out that it stays good, charges, no hiccups
But as soon as the battery goes below fifty it starts behaving too badly, takes time to start charging.

I'm so paranoid about using my phone while it's charging I avoid it as much as possible.
Since you've only had it for 7 month's or so, you should still have the manufactures warranty. You should send it in for service. I had a problem with my old ZL last year, and I ended up getting a new phone.

Battery Issue - Unable to boot after 0%

My phone has water damage. I currently have it in a bag of rice to hopefully bring it back to life. After a few hours I plugged it in to see if that would help, and I it had a strange activity. The LED in the phone handset was lit and green. I never rooted it to enable the LED. Any advice would be great!
PS: Sorry if this post is not the most coherent. I am currently very hungover, and having problems functioning. Also, I have no idea how my phone got wet! Happy Sunday to me!
Try a battery reset
The Dirtydee Z3
The led turns on when the battery is so low that the display can't turn on to show that its charging.
Device should turn on after sometime

As @adity said above, the LED turns on when your battery is too low to turn on the screen.
Charge it for some time.

Testing that now. Thanks for the heads up!
Fingers (and toes) crossed!!
You should've let it rest on rice for like one day.
On the good side, the moto x is kind of water proof.
Sent from my XT1058 using XDA Free mobile app
*Update*
The screen is now on and showing 0% battery. It has been plugged in for hours now with no change in level. I was able to get into FastBoot, however any option I choose results in the phone rebooting back to the battery charge level screen.
Thanks for the help!
*Update 2*
I plugged my phone into my cars 2.1 amp charger and after 20min or so it showed 100% battery. The phone booted, however it did not complete and turned off. When it did It read 0% once more. I have tried volume down and power for 3 mins with no result. Any more tips?
* update 3*
I pulled the back over off and held the battery ribbon down. LIFE!! Phone displayed 100% and it was running fine. However, when I removed it from power it shut off immediately.

I thought so too. I let it charge over night while it was cycling the boot screen, and when I awoke it was perfect. Battery 100% and turned on without issue. I understand letting your battery hit 0% is bad, but having it completely malfunction for 24+ hrs is rather poor play on Motorola's behalf.
How do you know that it's moto's fault?
Perhaps there was still some water left in your device?
This took longer to dry and caused the malfunction...
Don't judge so quickly!
I tell you this, because I had a motorola x with the same problem, the solution was to change the battery. Solved, try another battery
Dropping phone in water and having issues after is Moto's fault....? :silly:
I'll add... Water can and usually does wreak havoc on these things. Anything can go wrong after. Usually I'd say move on. Don't waste time or money trying to fix it.
You maybe were lucky. :good: But to suggest it's Moto's fault is crazy. Lol My X has died many times and 30 seconds on the charger and it boots. Anything you experienced was from the water.... Not a defect.

You put your phone in water, then turned it on again after only trying to dry it for a VERY short time. Bit amazing it even worked, and your complaining because it worked but only after drying?
Jesus man.
Pretty sure LIthium Ion batteries don't like going down near zero. Even when your phone says zero% and the phone automatically turns off it still isn't completely discharged.
I've let my nexus 7, and game controllers sit unused for a while. When you try to use them again they need a really long charge before they will work again.
The water probably put a load across the battery and nearly completely discharged it.
I actually just went thru this. I did the old school battery calibration using NeMa's app in the play store. Says to discharge 100%.. Phew lol. I was stressed. I had the same problems as above

Mix shut off on its own, won't power on.

Got my mix like 1 month ago. Stock miui and recently updated it to 8.5.4.0. No mods or unlocking the bootloader or anything like that.
Today, it was at 11% so I plugged it in the charger. 5 minutes in I looked at it and it wasn't charging, so I unplugged it and then it turned off before I could plug it back in.
Now it won't turn back on, the charging light won't light up. It looks dead.
I haven't dropped it or spilled any liquids on it. It wasn't exposed to extreme heat or cold and has a case around it at all times.
WTF happened? $650 down the drain?
What are some tricks I can do to try to save it.
I had a similar problem a week ago. Battery went dead and I plugged in the charger. But I discovered after an hour that it didn't charge. I tried turning on the phone, only response was a quick flashing red light. Tried different chargers, tried holding down the power button for a long time, tried the different butto combinations, no luck. Then I just left it in the charger, and after several hours I finally got a response from my beloved Mix. I took a long time to fully charge, but now it is working normally again. Phew! No idea what went wrong. But keep trying and hoping. Good luck!
To the original poster:
Has the phone powered on now? The same thing happened to me too.
My Xiaomi Mi Mix showed low battery sign so I plugged it in to charge. The phone immediately went off. I pressed the power button to restart it, it showed the Xiaomi logo then immediately went off and since then (this was 2 days ago) it has not powered on.
Kindly note the following:
1. It didnt have water spilled on it
2. It didnt fall or have any mechanical damage
The only thing was, the battery was low, I plugged it in to charge and it went off and never came on again. I have used the same charger to charge other phones so I doubt if the charger is the source of the problem.
Kindly help, what is wrong with the phone?
thanks

You could try unplugging battery overnight, watch a tare down first. It's not hard, I would be surprised if you have done any damage.

I havent tried any self repairs or anything funny yet the phone has remained dead.
What can I do now? This is extremely saddening
Mine just did this. My resolve was to hold down the volume up button and then plug the phone in. It should boot into recovery (down for bootloader) and from there reboot into system. I seems for some reason the bootloader is not allowing the phone to charge. You need to get around it.
Happened on mine in the first day. I even thought like why I bought a pos Chinese device. After 30 mins charging, it's started booting by power on button as it's supposed to be. Weird thing.

My Xiaomi Mix won't turn back on
this happened to my xiaomi mix yesterday. I was using it during dinner. Suddenly the screen wouldn't come on, flashed a bit, then shut down. I was able to hard reset it once. After that, the phone just died. and won't come back on. What do I do?
Please note: the battery was almost full. Did not drop it or get water in it.

Battery will need to be unplugged overnight, in the morning plug it back in, it won't boot or charge at this stage, leave on charge for a few hours maybe upto 12 after that it will be fine.

Have the same issue. During charging and watching youtube, it turned off. No signal since then.
Changed charger, tried PC... Also disconnected battery and charging for more than 24h.
Now have a new battery and USB board and no signal
Any idea how to get the data from it?

hey, i recently bought an used note 8, it has the broken screen, and the day i bought it i charged it at 100%, and keep using it until night, the weird thing is when i tried to charge it at night, the " CHARGING STOPPED. THE TEMPERATURE ON YOUR PHONE IS TOO LOW…” error appeared, para paradoxically the phone was a little bit hot, and it wouldn't charge, i let it rest a little bit but when, in the next morning i want to charge it, this happen.
