Z7 mini battery problems - ZTE Z7, Z7 Max, Z7 Mini

Is anyone else having issues with your mini battery overheating? It's been happening to me more and more over the past month. It overheats to the point where it's almost too hot to hold and if it gets too hot, sometimes it will automatically power off. I've read in some of the Chinese forums of this happening and people replace the battery. I've seen photos of some batteries that had overheated so much they were almost twice as thick as they should be. Anyone else?

If your phone is under warranty then have it repaired, if not buy a new battery.
It can happen, I read about it somewhere. But my phone heats up only when playing very demanding games, so everything is normal.

I read somewhere about this problem, but dont remember if there is some solution except of replacing it. If you have warranty then get it repaired. If not, you can find video on internet how to change battery yoursef. It's relatively easy work. You can buy new battery for example here: http://www.aliexpress.com/item/Orig...ZTE-Nubia-Z7-mini-NX507J-5-0/32247320316.html
There is a guide how to replace battery, but it is in chinese (you can follow pictures, its easy enough): http://www.tdbeta.cn/thread-247456-1-1.html

I had a battery problem toi. My battery was only during 2 minutes disconnected. Very annoying. Has i was sure it was a battery problem i order two new battery on alien express. I change it and now works like a charme.
Careful you normally just need to remove the protection to change you're battery. I followed a video who makes me remove every part of the phone... Useless.

Good afternoon

Super noob here. brand newe to all things flash Rom and what not. This HD2 will be my first phone purchased for the purpose of modding however...
After doing a search for the words heat and hot I was not able to find much, and the wiki is down
So my first post is has anyone ran into the isse of the LED blinking green and orange and slow to no charge while plugged into the wall? To the point where it no longer charges?
I work in tech support and ive never seen anything like it outside of my gateway laptop.
I was running the stock ROM no mods yet outside of the Android mod that is being developed. i have master reset the thing easliy 10+ times in the few days ive had it though im not aware of constant reseting having a negative effect.
Basically on my way home while sitting in my console in the car I went to use it and noticed it was warm past comfortable warm. I had not used it for extended periods like hours of browsing wifi calls or using the phone hard.
I went to charge it 20 min later and it got really hot again after only being on the charger for 15-20 min and had only charged up to %15 from %13.
Took out everything let it sit overnight same thing the next day, tried a new battery and charger ( even though the battery was barely warm it is hot all along the bottom half on the back and going up the sides) and still had the same problem taking hour or 2 to charge 2-5 % and staying very hot with no use.
Im at a loss as to what to think any ideas?

Heat will cause what you are seeing, but also check and make sure that one of your battery pins is not bent, seems to be a common problem ..
Also have seen a few people that their battery was just bad , and they had to get a new one shipped in .....

Sure cant make any promises but Ill be happy to answer any question I can. I work in Teir 3 PDA support so all of my knowledge is tech based. Ill look up the task29 stuff Im not too familiar with that.
since you have already tried a different battery, and if the pins aren't bent, then its likely to be the phones charging circuits. get it warranty replaced.

I checked and didnt see it any bent pins they spring out just fine when removing the battery and apon inspection seem to be fine. One of the 1st things was for me to try a battery in hopes that it was that simple but to no avail
More information for those that care. The battery has been out now for a full 24 along with the sim.
I got home today and put the battery back in no sim memory card stil in. After being on for 8 min the back is far beyond warm.
The memory card is not recognized and I am certain it was before. This is getting weirder and weirder.
I wonder if it has anything to do with me trying to run the android mod off of a 2GB card that im sure was a class 2 and below, then master resetting it and going back to the 16GB that came with it?
More to come as i try new things.
Now the high temperatures in Austria cause the same problems on my HD2 when navigating in my car. HD2 after 2-5 minutes blinks orange-green (no loading) and after maximum 10-15 minutes crashes and at home too (my little office room has no AC, is in direct sunlight and room temp is over 30°C.
Unfortunately I have to rely on phone, email and office-functions and on navi-function for my upcoming vacation. No solution to place the HD2 in AC-stream in my car with this stupid original HTC-Car-Navi-Holder, in the office I have to put it in the fridge before to get it recharged.
When driving in the heat of noon I don´t even have to switch it on, just mounting into the loading-cradle is enough to make the HD2 crash after 10-15 minutes, only 3G on, nothing else (no BT, WiFi, HSPA, no app running etc.)
Until now I was quite satisfied with the HD2, had no crashes or malfunctions so far, but now I am really fed up with this piece of sh.. and I don´t think there will be a hardware or software-solution (except swichting it off) since the HD2 is malconstructed. And it IS correlated with ambient temps since it started to happen only when ambient temp is higher than 30 °C. When I am in a AC-room everything woks normal again.
i think i figured it out! i took out the sd and used the phone for 20 min or so. the heat gradually went away and its no longer getting hot. i am currently posting from the hd2 with a standard 2gb card inserted and will test my 8 and 16gnarled card today.
there is an issue with certain sd cards not being "officially supported"....
I read a post on here earlier from somebody saying that their 16gb card was causing their battery to drain fully in a matter of hours because audio manager was constantly working through numerous gb's of music on the card.........
may be completely unrelated to your problem but since you mentioned the card I thought Id chip that in..........
Hope you find a solution.....

[Q] X10 shut off itself after heating up.

I would like to know if anyone have similar issue?
It wasn't as noticeable or i just can't remember if it does this before i updated with wolf cynomod 6.13 v4-v5 2-3 months ago on stock.
But lately, i found my phone shut off itself whenever it start heating up. I got a temperature measure app from market but it doesn't show me what exact temperature when it does this.
For example, after 5-10 min use of google earth, my phone will shut off and reboot.
Is there a way to fix this issue? or could this be an issue with my battery ?
It issue is heating because i have a plastic case with x10 in it, it would shut off 5 min after use with it and 10 min after use without it.
Sorry if another topic like this existed, i did a search and couldn't find any. Maybe i just got the wrong keywords.
yeah i experience the same issue ever since official 2.1 update came out. Figured it was just the phone called SE and they said its not Software issue but a Hardware issue and send it in with Proof of purchase.
My batter does heat up specially when im playing games and have it charging.
i read something about faulty the motherboard on some X10's.
Im never tried to replace the battery if u wanna give it a try and let us know if that helped you or not.
mine has restarted with no WLOD it's just weird but still no overheating
I changed my charger from Stock to the universal SE charger. Then I never faced any battery heating issues
I had the same issue with my Xperia X10. I had bought it from random guy without warranty. But i had luck that guy wasnt bad, and he came after 1 hour i called him, and gave me a new one Xperia. Now when i play 3D graphic games, it heat as hell , but never restart , if u have warranty go to SE and tell them about your problem , they should replace your motherboard and it should work good . Good luck in solving this problem. ( And sorry for my bad english )
I think it is a issue with the battery being able to deliver enough power on some devices. Mine has a tendency to restart when moving around, especially with wifi and GPS enabled. When I leave work, where we have a company wifi, the phone often turns off around the point when I pass out of the coverage area if I have wifi enabled. Wifi off is never a problem. I would expect that if it lost connection, it would try to send at full power to connect to another source.
This never happens if I drive, and plug it into my car charger. Therefor I think it might be the battery that is not able to power my GPS wifi and bluetooth at the same time...
This is a battery issue. Mine never had a problem but my friend's phone would heat up like that and shut down. Replaced the battery and all is good.

Intermittent charging (stock ICS, multiple charger, probably not dirty port..)

My girlfriend's Note started acting weird. When she plugs in the charger it randomly stops and starts, sometimes for periods of seconds, sometimes minutes. We checked every combination of cord and charger (AC and car), and they all do the same. We both cleaned out the charger port, but that didn't have any effect. As a matter of fact, just sitting there motionless on the table it will still randomly start and stop charging.
I also noticed that the battery level seems to be off. At one point it was down to maybe 20% (in the yellow). I rebooted and it was up to 30 (in the green). I don't have any real numbers, it was only something I noticed. It's not rooted so I couldn't clear out the battery stats. Instead I drained it down to 0%, charged it all the way to full while it was off. It seemed to help for a day, but the problem came back later.
Could it be battery? Or phone? She has at&t insurance on it, and we're going to run to the (official) store. I just don't know if they send it back or replace it. She can't really be without a phone, so I'm hoping it's the battery (unless they want to replace the phone on the spot).
All we know is you have an at&t phone. What have you done to it?
same problem with Samsung Galaxy Note
Hi there everyone, i'm having the exact the same problem and my galaxy note is acting just like that- weird !!
About two months ago I updated to ICS and after that no issues, only once did it not charge as it was supposed to until i turned it off, removed the battery and put it back in.
Only now has it been charging like explained above -- the charging process as well as battery indications would be very inconsistent -- that is to say, it would charge for some time and then stop unexpectedly, whether turned on or off during the process.
Also, recently my PC would not recognize the phone on Windows 7 anymore, whereas before that it had been recognized seamlessly.
I've been using my galaxy note for about 8 months now, as well as about 2 months on ICS, and only now has there been this persistent issue.
Also, I did not use it inappropriately, rather with extreme care. I also got a phone case and have been using orginal software and hardware only, so the phone has been properly handled.
However, I have been using it pretty much, so it might be "wear and tear" in terms of battery usage, even more so, because it's been regularly charging and discharging in the car or at home, at the same time. Still, what surprises me is that my PC would not recognize it anymore even when it's turned on. Then, at times it would also go to "car mode", although it is not connected to the car dock. These issues have come up just now, as well, so i can imagine it might be a software or even port-related issue.
Unfortunately, at this moment I cannot take it to the store i bought it from to have them check the phone, so that's why I'm trying to figure out the problem myself. After all, if it's software or battery-related i might be able to fix it without having it replaced.
The phone is not branded and free to use with any carrier.
@ Face of Boe:
Did you go to the store then and have it replaced or was it in fact the battery, or did they (you) fix the problem otherwise?
Any help would be highly appreciated.
Chris
Try your preferred mobile repair shop first.

I had this exact same problem a couple weeks ago...it all started one day at work when I had my phone plugged in (as I usually did if it was in one place for more than 5 minutes), but after turning on my screen for the the first time in an hour or so, I noticed that it hadn't charged at all! The indicator at the top didn't even show that it was plugged in.
Figuring it was just some kind of little glitch, I unplugged it, blew inside the charge port as well as the cable (old Nintendo habits die hard lol). Well as I went to plug it back in, I realized that NOW the indicator showed it was "charging", and my phone had gotten super hot in just the 30ish seconds it took me to blow the port and cable (heh.)
So obviously I freaked out and immediately shut it down, pulled the back, and removed the battery to let the two pieces calm down and make nice - before ultimately putting it back together and booting up after 15 minutes or so.
So the good news was that the "reverse charge" issue was gone...but the bad news was, the charge activity started acting literally word-for-word like your girlfriend's. Intermittent charging when it was sitting still, not charging at all for a period of time, losing more battery than it was gaining while it was plugged in and the screen was OFF...so yeah, it sucked. I did notice that I could push the cord back while it was plugged in and it would stay charging, but obviously I can't sit in one spot holding my phone for 5 hours a day - and that stopped working after a few tries anyway.
I spent countless hours on the internet, googling different phrases to try and find similar instances of this happening - but to no avail. Everyone's story was just a little different...and pretty much everything I found outside of XDA* was written by people over in England who dropped their N7000 in the snow, causing the charge port to be corroded. The conclusion from everything else I found regarding this issue for the i717 was essentially always "the only way you can fix this is to get a new phone, but you're screwed because this glitch causes the phone to look like it has water damage and therefore renders it ineligible for manufacturer warranty claim or even insurance claims".
To make matters worse, not only was my phone effectively unchargeable, but it was discharging at an absolutely absurd rate. I'm talking approximately 20% every TEN MINUTES!
So I got desperate (it's Sunday by now)...all of the cell phone repair places were closed where I live, but I was able to do some searching and found this guy that was surprisingly available at the AT&T store closest to my house. That kept me alive until Monday, when I was able to take it in to the guy who I've been going to ever since the iPhone days (he is FANTASTIC). So he looks at it, takes it apart, and in about 5 minutes he tells me that the small little strip where my charge port attaches to the mother board (or whatever) had a lot of cracks running across it that were causing it to short-out. He said that it's a very common problem with the AT&T Galaxy Note, I guess due to them using a pretty cheap part in that regard. This obviously explained the intermittent charging, the brief "reverse charge", and even the battery drain (if the motherboard was shorting out).
So what did he do?
Replaced the little strip that connects the charge port to the motherboard...took him half an hour...cost me $25. Advised me that, when I plug my phone in from now on, to try as hard as possible to keep the phone still and not move it around. So at least in my case, it was NOT the battery. If you'd rather be cautious and not take the phone into a store if you can avoid it, you can probably get a replacement battery online for just a few bucks and at least eliminate that.
So the moral of the story is: DO NOT try to take the phone in to AT&T store or deal with your warranty/insurance until you take it in to a decent repair place and have them take a look at it.
Hopefully this helps...I'm sure you are wanting (like I was) a software solution, but it is what it is. And just curious, did your girlfriend have any similar "reverse-charge" instances like I described above?
tl;dr: The problem is the charging port, not the battery. Should be an easy and inexpensive (<$50) fix at a legitimate cell phone repair location.
*The silver lining in this whole thing was that it caused me to stumble upon this forum...so I went from stock ROM, stock everything (before my charge port issue) to having flashed about one ROM per day over the last 5 days because I've been so interested in the entire world of customization that I only discovered after seeing a thread with "Gubment Cheeze" in the title (who WOULDN'T at least look at that to see what's up??) here on XDA and starting to read. I've been a 24/7 lurker ever since
I read the last post by cpa poke and I must say it's quite risky to actually have a phone repaired by an unlicensed dealer/repair shop, because you'll cause any warranty left on the item to be effectively void.
I do know it is tempting for any of us to get our phone fixed as soon as possible, but then I think we should keep it cool and try to work out what else we can to do to make it work -- even though it might be temporarily -- until we can return it properly, as according to warranty indications.
Any of you trying to get a "repair fix" might want to consider that it may well be rather short-lived, because the same problem could persist for some reason -- that your repair shop did not recognize. If ultimately you have to get it repaired again, your ("fantastic") repair guy might then not be able to solve the problem and at that point any warranty claim would be quite certainly rejected, either (because of any previous unauthorized modifications to the device).
As far as I'm concerned, I have been testing my device with different chargers, currently it's charging consistently while turned off.
Also, I don't think I have had any of the "battery drainage" problem while charging, rather the battery indications were rather unreliable.
Then, I have read the problem could be solved by changing the battery. So I'll see if that makes a difference as soon as I get a replacement.
Another option will be to factory reset the item. I'll try that as soon as I get a backup of my phone data.
To all of you who are stuck with this issue I suggest you try some of the above: different chargers, removing and reinserting your battery, or else a battery replacement, factory reset.
Also try and leave the phone for some time and try to charge it then while turned off -- that's how I got my phone to charge again (until now), and according to the battery symbol it's almost fully charged -- the issue might still persist after that, but maybe it'll work until I can fix it otherwise, or get a replacement. After all, if it's been handled properly we should expect to get it replaced.

While I agree that taking it to a repair place should only be reserved for desperate/time sensitive situations, the only reason I chose that route over going through AT&T or an insurance company was that, from everything I'd read, the symptoms alone would likely cause them to assume water damage - thus rendering the same scenario as if the 3rd party repair voided the warranty.
Im having the same problem with myGalaxy S3 today, random intermittent charging..
I Just took off the back cover a few minutes ago and found a little glob of water sitting above the charging port!! Aaah!!
Don't know how it got there, but going to let her dry out and see if it resolves itself.
info:
rooted S3 i9300
2 months old
ROM: Complex-D 2.1.3
Getting random freezes on this ROMfor a few days also, so going to flash a new rom and see if the problem persists
Is it me, or is this a retardly common issue with i717s? I've had this same issue twice. I replaced the charger flex board when I bought the phone in the first place. And now it hasn't been a month and the flex board seems like it's out again.
My phone had this issue and all I did was oder the charging port from parts4repair.com and it cleared the issue up

Are you using the Samsung charger for your phone? It seems you are over volted and burn your usb port.

Agreed .....and another thought comes to mind..
Non-OEM charger tips, especially car dock chargers and desk chargers have port tips using different material thicknesses.
I am speculating here, but it's likely that the off sizing would produce intermittent charging problems or damage to the device.
Of course, the overcharging effect would certainly account for rapid flex cable burnouts.
Without the cables and a micrometer, impossible to know for sure.
OEM is certainly preferable....g

I didn't know this was anything more than a myth. Though, I'm not sure this is my problem. I can charge the phone - for now - by putting the phone on my bedside table and putting a small weight along the length of the cable so it holds the jack at an angle against the port.
I know I'm gonna get flamed for that last statement.

[Q] ATT Mega overheating issues?

Hello, just wanted to post here and see if anyone else was having similar experiences with their phone.
So I have the ATT Mega, and it has been working fine for a little over a month now from when I first got it, love the phone. Last week or so, I noticed the battery would seem to drain much faster then usual and the back top part of the phone, where the camera lens is, would heat up very badly even when not using it.
I tried killing apps, restarting, nothing seemed to work. I checked the app manager and the battery stats, nothing out of the ordinary but the drain was there and the heat was so bad you really didnt want to hold it.
I contacted ATT and they sent me a replacement which I received last night. I turned it on and was trying it out and within minutes that phone started heating up in the same spot too.
They didnt send me a new battery because oddly enough the battery or that entire area in the back would not get hot at all, only the top half.
I contact them again today and they said they would send me a battery to try but I am scared it will not work again.
I also have a 64gb SD card that I use, but it is the same one I have used in my Note 2 and now this phone with no problem. I am currently using a Note 3 with the same SD and have no issues.
I would love to go back to my Mega though, I actually prefer it to my Note 3 but I am worried about this issue reoccuring or not getting fixed in the first place. Anyone else have anything similar to this with their Mega??
Mike
I have noticed it gets warm, but only when streaming videos. Just browsing the web or listening to music/iheartradio, nothing gets uncomfortable. I just notice the warmth after many minutes of streaming. Not uncomfortable either. Now I do have a case on it, so maybe that's why it doesn't seem as bad.
I have an i9205, but it's basically identical hardware. I've never had any overheating issues of any kind. Recently I've been running the "performance" CPU governor too, which locks the CPU at 1.7ghz constantly and yet I've never been able to make the phone throttle itself back.
Thanks for the responses! I am having ATT ship me a replacement battery to try that, hopefully it arrives today. I just dont understand why it would heat up so badly on both my original phone and their replacement one for me. I would think it has to be the battery or the SD card, but the card has no issues in my Note 3 and it didnt have problems in my original Mega for a month.
Crossing my fingers that it is just the battery so I can go back to using my Mega, I miss it -.-
I noticed my Mega getting warm in the same location last night, but didn't have battery drain. This is a replacement Mega since I bricked my pervious one, but never had that problem with that phone. Today, after being fully charged and not used while at work, I checked my phone and it was 15% and warm. So I turned off WiFi, GPS, and Bluetooth and plugged it in a 1 amp charger, 13% and still warm after a few minutes. Airplane mode, 12% and still warm after a few minutes. Turned the phone off and charging for an hour, phone is cool and 37% (makes since). Phone has been on, charging, and WiFi, GPS, and Bluetooth turned off for 43 minutes, phone is cool and 56%. Now I'm turning WiFi, GPS, and Bluetooth on individually to see if it repeats. I'll keep you posted on my results.
Thanks! I will wait to see your results!
Ive no issue with mine...
Well, sorry to say, it's been almost a month of me playing with this phone trying to duplicate my one time overheating with no luck. I've WiFi streamed for hours, transfered huge files over BT, viewed videos, and anything else I can think of with nothing. Maybe it was a fluke...who knows.

Its been 2 weeks since I got mine and I noticed the phone getting hot around the camera but it suddenly started being normal with no heating. Will try for few more weeks to see what is the temperature level

Hello, just wanted to post here and see if anyone else was having similar experiences with their phone.
So I have the ATT Mega, and it has been working fine for a little over a month now from when I first got it, love the phone. Last week or so, I noticed the battery would seem to drain much faster then usual and the back top part of the phone, where the camera lens is, would heat up very badly even when not using it.
I tried killing apps, restarting, nothing seemed to work. I checked the app manager and the battery stats, nothing out of the ordinary but the drain was there and the heat was so bad you really didnt want to hold it.
I contacted ATT and they sent me a replacement which I received last night. I turned it on and was trying it out and within minutes that phone started heating up in the same spot too.
They didnt send me a new battery because oddly enough the battery or that entire area in the back would not get hot at all, only the top half.
I contact them again today and they said they would send me a battery to try but I am scared it will not work again.
I also have a 64gb SD card that I use, but it is the same one I have used in my Note 2 and now this phone with no problem. I am currently using a Note 3 with the same SD and have no issues.
I would love to go back to my Mega though, I actually prefer it to my Note 3 but I am worried about this issue reoccuring or not getting fixed in the first place. Anyone else have anything similar to this with their Mega??

My friend kind of had the similar situation... in his case he changed the phone
My Samsung Galaxy 6.3 is getting hot on the ear piece and the back of the phone where the camera lense is. What's the problem? I need to know if I need a new battery or if it's the Motherboard I need to replace and will the phone blow up in my face till I fix this problem?

[Q] Battery "discharges" out of the blue

Hi,
My wife's been complaining about her sgs3, i9300a phone a lot lately, so I've been taking some time of to have a long hard look at it.
the phone in itself works quite well, it is somewhat guarded (she tends to drop it a lot but most of the time it's actually in it's case) and we've switched the screen once (well, not the screen, the top half of the phone to be exact)
the phone used to have a stock 4.1.3 (I think) samsung rom on it for the past year, it's been working well untill a couple of months ago I think and it does still function properly on light use
so what is the issue?
if you'll start a game, or anything that'll cause the phone to heat up - the screen would flicker a bit (not always) and the battery will suddenly report to be down to 0%, shutting down the device right after.
this sudden discharge is obviously not real, as the minute I connect it to a charger and boot up the phone it shows it's last charge before the phone was shut down - however the issue keeps on repeating itself over and over again.
If the phone is connected to a wall charger (or a pc via USB cable) this doesn't happen.
I've been trying to install a kitkat on the device (it have been working slowly so she needed an upgrade) yet the issue persists.
I've been reading around the Internet, some claim it's a faulty battery issue so I'm ordering one from eBay, however - I can't shake the feeling it might some other faulty hardware, perhaps a memory chip gone bad? as I can't see the connection between a bad battery and a flickering screen.
Truth to be told - I'm not a fan of android, or samsung, so I don't know much of the history of problems with it (if there is any) and I've been hoping that there is someone around here who might encountered (or heard) about my issue and would be able to shed some light for me.
thanks in advance!
Change the battery first, replacing the motherboard isn't worth it.

Yeah... I'm planning on stealing my boss S3's battery for some testing later on today if he'll ever decide to show up...
perhaps shouldn't have told him that beforehand
I did hope someone encountered and fixed/learned about this problem as the device has 2 years of history at least...
if it'll come to motherboard switching I'll just force the little lady to switch to a real phone such as an HTC, or maybe go to WP
It was the battery..
Perhaps I should've guessed it by the fact it was REALLY hard closing the case... but it was only after I saw a normal battery that I noticed the real difference.
so for future reference to whomever might meet the same behavior - my battery was about 1.5 the size of what it should be and was quite round,
better call those Samsung representatives and get a replacement before it explodes
Anyone has experience with those 4200Mhz batteries? worth the money or should I just get a genuine one (it cost about the same in here, like 4$ more), the reviews are quite mixed.
