[Q] Charging Interrupted - Battery Temp Too High or Too Low

I recently received a Droid Charge from Verizon as a replacement for a Thunderbolt which was basically rendered inoperable by the May OTA update due to near constant rebooting. I really like the Charge (with the exception of that hideous brown/orange theme - some of which looks designed by 1st graders!), but I'm having a MAJOR problem with it that I haven't seen mentioned anywhere else, and I'm wondering if I'm the only one suffering this issue!
I drive a tractor-trailer for a living and use Google Navigation as a back-up to a truck-dedicated GPS unit I have in my tractor. I have a dash mount that I used to keep my Thunderbolt in and I had no problems with it at all (except for the constant reboots). However, the first day I was using the Charge, the screen went dark all of the sudden after a couple of hours, and I'm like WTF?!! I couldn't get it to anything, so I pulled it out of the dash mount and let the sun shine on the screen - I saw the display was still on, but it had dimmed to the point that I couldn't see it without a light shining on it. In the middle of the screen was a dialog box with an exclamation point and the message "Charging Interrupted - battery temperature too high or too low"! I unplugged the Verizon-branded car charger and as soon as I did that, the screen became bright again, and the message disappeared. I left it like that for a while, until the low battery warning appeared. I then plugged the car charger in and let it start charging. Well, guess what? It darkened the screen again after almost 30 minutes of being connected to the car charger, and I saw the same battery temp too high message on the screen!
I have since tried to use the wall charger I got with my HTC Thunderbolt (my tractor has a power inverter in it, and electrical outlets to plug a power cord into, just like the outlets at home), but I got the same warning message on the screen. This is a REAL problem as it's basically causing the phone to be unusable, since I am not able to charge the battery when it gets low, due to the phone interrupting the charging! I went to a Verizon store, thinking it might just be a bad battery (especially because, when I first put the battery in the phone and plugged it in to charge, I got an "Incompatible battery" message on the phone). I took the battery out and reinserted it, and I never got that message again. Verizon gave me a brand-new battery, but that didn't help. They sent me another Droid Charge to replace the first one, but the 2nd one is doing the same thing!
Anybody have any idea what's going on here? I've had the same problem now with 2 seperate batteries and two seperate Droid Charge phones, but I never had that problem with my Thunderbolt, even though I used the same wall & car chargers with IT! The back of the Charge's are getting very hot, but, then again, so did my Thunderbolt, and I never had a charging issue with it. I'd really like to keep the Charge and send my Thunderbolt back to Verizon, but I can't do that without finding a solution to this problem!
Thanks,
Dennis

I used to have this issue with several HTC phones. What happens is that if you keep the phone on the dash in direct sunlight, the battery reaches critical temperatures and to prevent the risk of failure, it stops the battery from charging. This happened all the time on my HTC phones from the Mogul 6800 to the Touch Pro. Not sure why the T-Bolt didn't have that issue, maybe it was set to a higher threshold before stopping the charging.
You may want to keep it out of direct sunlight or take the battery cover off to let more air flow in when charging on the dash.
Hope that helps.

I had the same problem. The warning message seems to be a safety feature built into the Charge that waits to charge the battery until it is cooled off.
I found that unpluging and turning off navigation for a while helped cool things off.
I also tried having the phone fully charged before using it for navigation and then plugging it in and this seemed to help. I am no expert, but it seems that when the phone is not trying to charge a battery rapidly it deals with the GPS heat better.
I hope this helps; stick with it and keep bugging Verizon!

So they sent you a Charge, but you kept the tbolt charger? And they have sent you multiple Charges and batteries, but never the correct charger? If this is right, you need to tell them to give you a Charge charger (heh). This phone seems to be pretty particular about what charges it, I can't even use a usb extension cable, so the wrong charger may be the culprit.

I've been getting this as well using CoPilot Live v8 (just upgraded to v9). I found if I turned down the screen brightness a bit, say to 80%, I could still see the screen but avoid most of the battery charging issues.
I also just purchased a Tetrax XWAY mount that will attach to an air conditioning vent. We'll see if blowing cool air onto the back will let me drive around with the brightness turned full up.
My concern with brightness all the way up is that I am not sure if the charge rate from the lighter plug will keep up with the discharge rate on the DC when everything is running full tilt...I just ordered a Tek-Tok Wireless lighter plug USB charger, Input: 12-24V DC; Output: 5.0V DC 2.1Amp! Let the frying begin!!!
p.s. I tried the Samsung/Verizon navigation mount on a 5-day trip...not too bad of a design, BUT, would not work with my extended battery and back PLUS when the DC goes into car dock mode (automatically when inserted into the navigation dock) it comes up with a screen that has a shortcut to VZ Navigator that CANNOT be edited or changed to another navigation program. You have to disable the dock in order to use another navigation program! What's with THAT, Verizon and Samsung!!! Needless to say, returned the mount yesterday...

Try turning your brightness down, make sure it's going into sleep mode and keep it out of direct sunlight

I also had the exact same overheating issue. After getting a replacement device I started looking at the charger I was using. I had been using a micro usb charger that only output 500ma. The droid charger is 1000ma (or 1 amp). Apparently I was using more power than the charger could provide. The charger couldn't keep up and I guess that must have been the issue because since switching to a 1 amp charger, I haven't had overheating issues.

"Charging Interrupted - battery temperature too high or too low"
Living in Miami, I have seen this message a few times after leaving the Charge in my car.
Run a free sensor program to tell you the battery temp when it does this. Mine gets up to 130 F.
If your phone isnt really at 130F, maybe something is tricking the sensor or it is faulty.

I rooted my Charge today, installing a new kernel (imnuts' PeanutButta Jelly Time) and a new ROM (GummyCHARGED 1.8.5), and I drove 3 1/2 hours from my terminal back to my home for the weekend with the Charge plugged into the charger and never once got the "battery temperature too high or too low" message!
I'm keeping my fingers crossed that doing this eliminated my charging problems with the Droid - we'll see!

Google maps updated and one of the new features is "Improved battery power management for Navigation (Beta)." Hopefully this helps to solve our problem!

One thing I did to help prevent this issue when it gets to hot is to set the air vents in your car to the defroster setting, so it will blow air at the windshield, and in turn your phone on the dash. Also, taking off the back can do wonders to prevent over heating.

Overheating phone, owner (me) freaked out

I have a Motorola Droid 2 Global running CM7. It works fine, other than the usual quirks of a custom ROM, but it gave me a bit of a scare yesterday. Here's what happened:
- Battery was low, 28%-ish, because I hadn't charged it for 2 or 3 days
- Plugged USB from the netbook to charge it (I lost its AC adapter somewhere in the junkyard that I call my home)
- Unplugged it after only a few minutes because I had to go out in a hurry, battery had reached 30 or 31%. Dropped it from a height of about 50cm while doing so; a bundle of wires cushioned the fall (the phone has survived *much* harder falls)
- Stayed out about 20 minutes, nothing unusual to report, phone working fine
- Came home, put it on the desk, went about my business for about half an hour
- Found it blinking red, only noticed because a notification (stupid Astrid Task reminding me I should use it) made the screen light up
- Grabbed it and it was *hot*, hotter than it had ever gotten before and way more than anything this small has a right to get. Battery was down to 1%.
- Fearing a short I panicked and pulled the battery, then left everything to cool down.
Well, a short it wasn't otherwise it would have stopped working entirely; rather I think for some reason all of the hardware was working 100% constantly, though I'm surprised at just how much heat that can put out. There was nothing weird about the phone's behaviour up until this. A software bug? It had a really long uptime, something like a month and a half without being turned off (I keep it in airplane mode at night)... I've heard that Android in general and custom ROMs in particular can freak out if they're left unrebooted for very long. Otherwise it would have to be a hardware problem, but it's a weird hardware problem that leaves a phone working even while it bakes itself.
I'm recharging it right now and no abnormal heating is going on.
W, I ask, TF?

I feel your panic. My HTC Sensation can heat up even from browsing the web to around 40 degrees centigrade Sometimes eve too hot to hold.
Sent from my HTC Sensation Z710e

Got an Optimus 2x that gets way hotter when using than the Desire it replaced. It also has a cheap Chinese battery which I strongly suspect does not work as it should. Perhaps your battery is giving problems and needs to be replaced or there was a temporary problem with the charging circuitry?

[Q] Nexus 5 INSANELY Hot to the Touch When Wireless Charging

I'm wondering if anyone else has run into this or has any ideas as to what may be happening...
I've been charging my Nexus 5 wirelessly at home and at work with my TYLT VU wireless charger. The N5 is listed as compatible on the Tylt website, so I don't think that is the issue. It has been charging successfully overnight since I got the phone about 3 weeks ago. However, for the last two days, I wake up to find the phone has stopped charging at 80% and 84% yesterday and today, respectively. Also, the phone is INSANELY hot to the touch, to the point that it is unsafe to hold. I have to set it aside to cool for a few minutes before I can handle it.
Yesterday, I thought it was a one time glitch, and that I hadn't placed the phone properly in the charger. But last night I was careful to lay it in the charger so the green light activated. No improvement, same result.
Notes:
- The phone is in a Spigen case
- I do NOT have Developer Options enabled
- Stock Android, locked, unrooted
- YES, the screen times out after about 2 minutes (does NOT stay awake)
Any ideas? I'm really worried about the phone getting this hot and not charging.

its probably your charger. mine gets warm but nothing insane. i charge during the day in my cube and typically have a full charge when i leave, and it lasts all night till i get back to work. so i basically sit by my charging phone all day and its never really caused me any concern. i have a knock off "qi compatible" charger from ebay. works great for $20

Holy s*it that thing is expensive. Sounds like there is a process that is getting triggered by charging and running the cpu to 100%. Think about a new app installed since heating started. Ordered 2 of these with no odd heating of device.
Off topic: What would developer options being enabled or disabled have to do with wireless charging? (just wondering)
good day.

Have you tried it out of the case? Maybe it's not vented properly in it
Sent from my Nexus 5 using Tapatalk

I saw several comments about this very thing in a qi charging thread after the phone started to ship and they all used that charger. Most said it ended up being a one or two time thing but the charge you mention was common to all the situations. I suggest getting better battery stats from XDA and then check it after charging. Also try charging in short half and hour to one hour time frames until you know it is not truth so hot.

Mine doesn't get noticeably warmer charging on the Nokia Qi plate than it does over USB. Maybe you should contact Tylt.

Developer Options is where the "stay awake while charging" setting is. I just wanted to make it clear that I didn't have that setting enabled. That's all.

Thanks for all of the help everyone, hopefully this was just a random incident. It's charging fine now at work: on the VU, in the case, at 100%, no overheat. Weird. I'll try it again overnight tonight and see what happens.

Or maybe the case causes the heat because of the added distance between the charge pad and the coils in the phone? Dunno if that's possible tho? Lol

There's something about that Tylt Vu charger that sometimes doesn't recognize when the phone is fully charged and go into trickle-charge mode, as it should. (Although I've never heard a conclusive answer as to why the battery is usually found at a low charge percentage, so there may be another reason.) There are numerous reports of overheating with that specific charger. It doesn't happen all the time, and in fact, many people report that it works fine for weeks, then one day it does this, then works fine for weeks again. Still, it's a VERY common problem with that charger, and it only takes one time overheating to damage your battery.
I'd contact the manufacturer and see what they'll do about it (refund, working on a fix, etc.). In the meantime, you could try the Nokia DT-910. It's a similar stand-up type charger, and doesn't seem to suffer from the same problem.

Glad I'm not alone. Thanks for the link.

I realize this thread is old but this happened to me last night. I woke up this morning to my Nexus 5 shut off (it was turned on when I placed it on the charger) on the Tylt Vu charger and when I picked the phone up I couldn't hold it comfortably. It physically hurt to hold my finger on the screen. I have never felt a phone that hot before. I would imagine it shut down due to heat but shutting it down didn't stop it from continuing to charge in some sort of error state.
I am done with wireless charging. I am actually curious what would have happened if I had left it all day. I truly believe I'd have ruined my phone or started a fire.

[Q] TYLT Vu and Overheating

Since there’s a fair amount of posts that note this, particularly with this charger, I figured I’d start a poll. If you have a TYLT Vu, have you run into the overheating issue/does your Nexus get uncomfortably hot while charging?
FWIW, I have two Vus and have not had this issue, at least not yet. While the phone does get warm, it’s not hot and I would consider this to be expected. I also happen to keep the phone in this case: http://www.maxboostpower.com/shop/m...stand-fits-all-versions-of-google-lg-nexus-5/.
UPDATE: While I have not yet tried this, an XDA member has some steps for reproducing the issue consistently, and subsequently how to potentially avoid it, at http://forum.xda-developers.com/showpost.php?p=49282197&postcount=119.
UPDATE: Lastly, we have acknowledgement from TYLT on the issue and how to work around it—maybe they’ll become a responsible company one day and actually fix the problem one. From http://forum.xda-developers.com/showpost.php?p=49467213&postcount=157:
Hi ****,
Thank you for contacting TYLT customer support. We actually found a solution for this issue, when you place your phone on the VU put the bottom part of the phone onto the base of the VU at an angle so the screen is tilted towards the ground a bit then put the back part of the phone onto the VU. This way the middle coil will be activated which is a perfect match for the coil inside your phone.
Please let me know if this solves the issue.
Thank you!
Thanks,

Cheers.

I haven't had the issue with mine.

I've had one of these for just over a month and I leave my phone in it to charge every night. I also use it regularly as a stand when I'm at my desk.
The phone does get warm while charging, but no warmer than it did when plugged into the stock charger.
It takes about 3 hours for my phone to charge from <10% to 100% (about 30%/h).

How to you define overheating? I have two TYLT and the N5 tends to get warmer by a few °C compared to other Qi chargers. However, it depends very much on the actual battery status (SOC, temperature) prior to starting a charge.
I have also noticed that turning off Day Dream reduces temperature rise during wireless charging by about 3-5 °C in average.

I’d guess I’d simply describe is as uncomfortably hot. While I haven’t experienced the issue myself, the people who have tend to describe it this way. I’ll make the OP a little clearer.

I have three wireless chargers, the Nexus charger, Tylt Vu and an older WPC-700. Same issue with all three, sometimes they're slightly warm, other times they're hot. No rhyme or reason as far as I can tell.

Welp, add me to the list. Just pulled my N5 off the tylt and the back near the camera was almost hot enough to burn me. Charge stopped at 85%. It's become pretty warm in the past, but nothing like this. Very alarming.
Can't help but wonder if it has something to do with the metal discs in the N5 and the multiple coils in the tylt... It's like putting a steel pan on an induction cook top.

No heat with mine. I leave my phone on it all the time. At least every night, sometimes during the day as well. It is never warmer than when charging with the standard USB charger. Same goes for my Nexus 7.

I have a one and I've noticed the N5 getting very hot but only if I leave the screen on and slightly hot during Day Dream so now I just make sure the screen is off and everything is okay.

I DEFINITELY feel it get warm... haven't noticed it coinciding with screen being on for periods of time, but my screen WAS on last time it got super hot...

Mine overheated once overnight. In the morning the N5 was so hot I couldn't hold it in my hands.
http://forum.xda-developers.com/showthread.php?t=2522361

My N5 has also gotten very hot numerous times, too hot in my opinion when using the tylt. Doesn't happen every time though. I've tried to determine if it has anything to do with placement, but have not been able to tell. I also have a Google Nexus wireless charger and the phone never gets hot when charging. I'm now trying the phone on it's side on the tylt and will see if it continues to overheat.

I had my Nexus 5 overheat once when I pulled my Nexus 4 off the charger and place my N5 on immediately after. Woke up in the morning and the phone was off and HOT. No issues since but I never charge one phone right after the other.

Happened again! The back of my phone measured a little over 130F. Starting to think something has gone wrong with my VU. I've owned it for a month and haven't had a problem, now suddenly it's attempted to deep fry my poor N5 twice in the last week.
Emailed TYLT about this, but not confident I'll ever get a response. Seems like they've been ignoring emails lately.

My N5 overheated (to the point it stopped charging) every day on my Tylt for 4 days until I disabled Daydream, now it hasn't happened since.
That said, looking at Battery Monitor Widget tells me it's still charging too warm (40-46c) just not warm enough to trigger an overheat warning. Daydream probably just pushes it over the edge.
My guess is this is a fairly common problem with the Tylt and the N5 due to the metal disks the N5 has for magnetic alignment - something I'm not aware of many, if any, other Qi compatible phones possessing. The Tylt has 3 coils and a 1amp charger which lets it charge faster than other Qi chargers but probably pushes the envelope in the process.
Could vary between models, I guess, but I wonder how many N5 users with Tylts who also use Daydream (or otherwise have the screen on when charging) have this issue?
Also I've read that charging in landscape helps - slightly more airflow around the back of the phone, and less of the metal disks come in contact with the coils I bet are the reasons.
PS: I have the stock Nexus Qi charger (the new one) on my dresser and a Nokia N910 at my office and have no problem with either of those - and temps stay in the 30c range. Both of those are also single-coil chargers powered by 500mA US and charge slower than the Tylt as a result.

Welp. Unfortunately, it looks like I can be added to the list of those who have been "burned" by the Tylt Vu. I've been using two different ones for about two weeks now with no issues at all. The hottest my N5 would ever get would be around 37C (but it would usually hover around 34-35C). I've been keeping an eye on the battery temp since reading all these horror stories of overheating. Tonight, it was charging fine when I picked my phone up to check a text and mess around for a couple minutes. When I put it back on, it was probably around 37-38C or so. I was sitting next to it and touched the screen to check the temp, and it felt REALLY hot (only about 5-10 minutes after setting the phone back down to charge). So I took it off and the battery temp was showing 49.5C with "health" saying "overheating". I always make sure the screen is turned off after putting it on the charger, so I know it wasn't in daydream or anything. Kinda freaked me out. I love these chargers, but my faith in leaving them unattended while charging is now shaky at best.

I have a cheap Chinese QI charger for 21$ single coil its charging faster than the wall adapter AC i plugged it into a Asus Nexus 7 2Amp charger and it doesn't overheat at all i think this overheating has to do with the Tylt having 3 Coils instead of One

I've never used an app to look at internal temperatures. Do any of them have an alarm that would sound if the temperature went over a certain mark?

Mine was hot several times when an app was running in the background. Since then I've made sure that all apps and antennas/radios, and the screen is/are off. I have two vu. Same problem.

You can use tasker and have the phone ring on battery overheating condition but to my knowledge not a specific battery temp. It's kind of too late but at least the phone won't sit there and continue to cook.

The screen can be completely out when this happens. It runs a bit hotter during normal charging with Daydream but its definitely not the cause of the overheating condition.

BTW, for the record mine has overheated twice in excess of 132 F and stopped charging at around 70%

My S7 startet a small fire at the charging port. Did anyone else experience that?

It was not the battery but at least the charging port burned during fast charge.
I was using the officially supplied Fast Charger which came with the phone.
Seems the phone got so hot that it switched off. The phone was lying on the carpet while it happend. Luckily it didn't lit the carpet next tpo my bed while I was sleeping...
I've put detailed info into this video:
https://www.youtube.com/watch?v=GxeYSV8toXA
Samsung picked up the phone today, waiting for their reply.
As far as I know there was no damage on the phone prior to the event. Even the Liquid Damage Indicator is ok.
The Phone was 6 month old.
Should I better use wireless charging overnight in the future? Any experience?

Scary
I would not charge that phone in any possible way...just in case
Let us know what they tell you when you get the phone back

yea i would use a wireless charger because i think the rubber protection near the charging port gets weaker after months of use with the normal charger. You can buy a fake wireless charger for 12 bucks on aliexpress.

Wow, things are not good with Samsung and their exploding / catching fire phones, this is slightly worrying that it's happened with an S7
Lucky that it did not go any further than the charging port, especially if it was on the carpet
Perhaps it overheated because the back of the phone was on the carpet and not a solid surface where heat could escape, but they should not catch fire, just overheat and shut off charging and power
Keep us updated with what Samsung tell you, I don't fancy this happening to mine

It lay down with the display-side to the carpet. It was the same way as every night. Floor-Heating is still off at this time of the year. Room temperature in our sleeping room is around 18°-19°C (~ 65°F)
So this should not create a heatspot. And I never noticed that the phone was so hot that I was afraid it might catch fire.

No, that definitely should not have caused it to overheat
I hope Samsung are honest with you about the reason for the fault
And tbh, it doesn't seem like an overheating problem, it sounds more like whatever the fault was, caused the battery to overcharge and overheat
I think you are very lucky this didn't cause another battery fire

Are you using the "fast-charging" option? I would recommend disabling that,

This was my main concern since I bought my s7 in july. I noticed that when it's charging with regular 2A/5V option, the plastic on the port which goes into phone gets warm. On fast charging it doesn't get warm, because the voltage is higher, but amperage is 1.60A.
Does anyone else have this "problem", or should I replace my cable? I don't want to end up with a fried port too.

since the spot of where it burned is at the contacts it was probably just a short because moisture between the contacts or maybe conductive debris got in there.
also its normal for the battery to warm up during peak charge.
