[Q] Frequent Random Shutdowns and Reboots - HTC Amaze 4G

I've been getting these A LOT since the second half of summer and it is really annoying. My phone is not rooted and is on stock ROM with the latest update. I always have to remove battery and put it back in place to fix it, working for only a hour or so. It was also weird, because I'm thinking this could be battery issues, is that is this a problem with the current of power going to the battery when charging? Because when I'm at my house, it says the power current is too much, and then when I went on a vacation in Las Vegas, I charged my phone there and it seemed to get fixed just a bit. Bit I still am getting these random shutdowns and reboots.

First of all i thought it was a software issue..I removed sense launcher & it worked very well for few days..Then it started again..This time i've change the battery & still haven't got a single shutdown or reboot.

Hm, so it's more of a physical battery issue...I had a feeling too. It must've been affected because of my crappy outlet.

Phone Not Charging Thread

This is now happening on my replacement phone! I got the first phone replaced because it wasn't charging but now it's happening again on the replacement. It seems to only happen when the battery gets to 20% or lower. When it does this, it doesn't matter if it is USB or wall charging. I have been able to get the new phone to charge now twice by rebooting - one time it took three reboots. The first time it happened on my first phone the battery widget stuck on 50% and I didn't get the low battery warning and the battery went to 0 before I knew it and it took forever to begin charging again. I've been on different battery modes when it happens, so that isn't causing it.
I've mentioned this on a couple other threads and there's been others that responded it happened to them, so I thought I'd start a thread on this in case Motorola is monitoring this forum (they better be). Anyone else chime in here so we can get a feel for how widespread this may be.
Just let mine go down to 20 plugged up and its charging but im only on day one

Have you tried doing a hard reset and letting the phone sit for 20 minutes. It could be some kind of bug. I know mine had some force closes on the first day. I did a hard reset from recovery and let the phone sit at first boot. Then did a reboot and have had no problems since.
Master reset for photon 4g.

I did a factory reset on the first phone and that didn't change this problem.
I haven't seen this problem on my phone. Best thing to do is report it to the Motorola forums and have them look at it especially if many others are experiencing the same issue.
In the mean time, you possibly could have another bad unit. Not sure why it would not charge when the battery hits 20% or lower. Also what battery widget are you using?

Good idea on the Moto forums. I have tried Battery Monitor widget, Circle Battery widget and Battery Notifier (big text) widget. No one widget was in use or installed for every instance I had a battery charge problem, but I guess it may be more than one widget with potential interferences. Has anyone else been using any of these widgets and not experienced this problem?
@Beartrap
What battery widgets etc have you installed? Sounds like a compatability issue with something that was installed. Try using the phone completely stock with no custom widgets installed. If you can get the phone back to stock out of box condition that would be the best way to troubleshoot this problem. I doubt it's another bad phone.

I agree it's not a bad phone, but some bug either in the phone or installed app/widget. I'd like to know what battery widgets people are using that haven't had this issue so I know what's safe.
Not exactly related to battery widgets but i have noticed that Estrong's, Astro and File Expert file managers do not work correctly on my Photon. They don't show the full capacity of my 16gb sd card and they also don't show all the files in my download folder. So I'm thinking theirs going to be more incompatability issues with this phone until app developers get some updates rolled out for this phone.
As for battery widgets, i don't use them. I use the stock battery ifo that is included with the Photon. Sorry I can't give any help with that. but I'm pretty sure the widgets in the Android Market will not be fully compatible with the Photon. Uninstall everything you installed from the market and use your phone for a day or so and see how it acts.
I'm having the same issue, i'm not using any sorta battery widget/app, just stock(non-rooted).
Its been charging for about 4 hours today and went from 20% to 30% and its hot, really hot.
I've had it since day one and seems to match what the OP is saying about once it goes below 20-30% it has a hard time charging but like i mentioned before, mine gets toasty when its failing at charging.
Also had an issue while streaming from google music beta, went from 100 to 20% in <2 hours and once again it was hot as the devil's **** then it wouldn't charge.

I did fail to mention that each time I did notice the back of the phone was pretty warm but not what I'd consider real hot. The third time this happened (on second phone), I cooled it down to room temperature and it still wouldn't charge.

Well it got hotter the my evo 4g ever did after flashing many roms and kernels and what not and even hotter the my pre minus when simultaneously charging and tethering. Havent had a phone get that hot before, i'll try to get a temp reading when it happens again.
Just pulled the battery little while ago and it started charging again. Seems to be hit or miss with the restarts and battery pulls the get the thing going.
I havent tried just turning it off and letting it charge past 30% yet, to see if it only does it when it on vs. when it off.
It's happened again. I was running speedtest.net repeatedly to test my radios and my battery temp climbed up to 118F. I checked if the phone would charge periodically and it did until the battery got less than 30%. It seems to be this combination that causes the malfunction. I rebooted and it charged fine, but the temp also fell to 115F, so I don't know if it was the reboot or lower temp, but at least now I know how to get it to recharge and not run th and it always charged, battery down to 0.
I tried to make this happen the other night by running quadrant repeatedly, but temps never went above 115. It always charged that night, so 115-118 is the magic number together with <30% battery.
BTW - our radios may kickass, but they also generate a lot of heat, so be on the alert to high battery temps when hitting the radios hard.
My first Photon had the problem where the battery went from 50% to DEAD immediately. I remember one time the phone was red hot to the touch right before it died, it was just idling. It wouldn't accept charge until I removed and replaced the battery.
My replacement Photon doesn't have the problem (yet) or any of the first Photon's problems. I am convinced there is a bad batch of Photons out there.
Unfortunately I'm on my second photon. I exchanged the first for this reason.
Do any of you happen to use a case with a magnet in it? I've only had this happen twice and both times it was in a case. Now it doesn't happen.

I am using the black Sprint case, but there's no magnet in it. I do think the case may aggrevate the heat buildup so if I hit it hard again and feel it getting warm, I'll be sure to remove the case.

This theory just got shot down. I hooked up the USB charging cable at 62% and 84F and it wouldn't charge. The phone recognized the connection and displayed the message it was in charge mode, but the battery in the notification bar didn't show it was charging nor did battery monitor widget. I then connected it to the OEM wall charger and cable and nothing. I rebooted and no change. I shutdown the phone and hooked it up to AC and it went into charge mode. I then booted and it's going into charge mode as it should. I'm back to square one again.

That doesn't matter, you have every right to exchange it 283892 times until you get one that works. within the 30 days, It is in our contract. Not sure why people don't understand this. It doesn't matter where you get it, what store you get it from, Sprint, Best Buy, Radio ****, bob's electronics supply..you can get it exchanged. Personally, I wouldn't have even hesitated nor made this post, I would have just exchanged it.
Then made this post to say what happened to a photon I used to have. lol
EDIT: People need to speak up and let companies understand that you just won't settle. I come across customers everyday that just settle. I work for Comcast, talk to customers daily about things. I get, oh yea and then our internet sucks, and this doesn't work and oh yea this broke and we don't get this channel but we pay for it. My first question is, "Did you call?"....their answer, "Call who?"..or just "No". LOL I'm like, how the hell do you think stuff will get fixed if no one knows you have any problems? haha
You are the consumer, you have a lot of rights to the product you paid money for.
This is a great phone, but like all electronics some stores might get a bad shipment, it happens.
Good Luck with whatever you choose to do.
I have exchanged mine 2 times, 1 had a messed up screen, the other 1 had some problem that I couldn't make calls. So far this one is good to go! The Charm

Random reboot-solved, hope this helps someone.

I know more than a little about Android. I've been hacking and Romming since back in 2007. Last Friday my 3D started rebooting randomly. I tried everything I know. Reflashed different ROMs, same thing. Reflashed the aio 2.17 update. Same thing. reflashed recovery(twrp), same thing. Got 4ext and flashed that, same thing. I didn't know what else to do. Copied all the card to PC, reformatted and copied back, same thing. I had some clues, the GB ROM i was running (CleanROM Reborn) would sometimes report 0% battery. It also would almost never reboot on the charger,
I installed a fresh ROM (MeanROM ICS) and all seemed fine till it randomly factory reset while I was at a gig Sat night!! A week or so ago I was in Austin and left it charging in the car and went swimming. When I got back the battery was reporting overheat. I cooled it off with the AC vent and all seemed well. A few days later, I had a bootloop, thought it was the kernel and did a battery pull. Somehow I must have gotten something on the contacts or didn't seat the battery. I pulled the phone out of my otterbox today and cleaned the contacts and put it back in. powered it up, haven't had a problem since (knock on wood) I'm planning now to get a replacement battery in case I fried mine but only time will tell. I hope this info will help someone at least try the simple stuff first without all the headaches I've had the past 4 days.
This issue happened to my evo 3D : it turned off without reasons.
Sometimes, the battery icon became grey so impossible to see the battery level and few minutes after, it turned off.
One day, it turned off and impossible to power up. I sent it to the repair center and the issue came from battery and other components (contacts with the battery). After other comments on the internet, I'm not the one to met this problem so if it can help you I think that some evo 3d have this issue natively.
PS : sorry for the possible mistake in this message, my english is so bad
to fix random reboots, power off your phone to clear the cache, remove the battery for 30 seconds, place it back in, and power it up. Once it boots up completely, reboot your phone (don't shut down just restart). You should be good. This clears up the bad cache that causes rebooting.

Good post. Yes, I can see this happening for sure. My battery seems a little loose but I have not had this problem. If it turns out I ever do, then this would be my first guess.
I once had an Acura Legend that for no reason would just stall on the road and die. It was very irritating. One time had to have it towed. I had it in two different garages and neither one of them could fix it and told me there was no problem. But sure enough it happened again. The problem was intermittent.
I had it towed again home to my driveway. I'm sittin in it and thinking. For some reason I started jiggling the keys in the ignition and it would start and stall just by doing that. It was a bad ignition switch. I had never had one go bad before. I replaced it myself and all was well.
I went back to one the garages I took it to and told them I found the problem and what it was. The guy said yeah I knew that was the problem and said he told me so. I could have strangled the guy. Never happened that he told me that. They had even charged me $75.00 for fixing nothing. I never went back to that garage. The other garage I didn't bother telling.
Anyway, your battery problem reminded me of all that. Something I'd rather forget about. Thanks.

Yes that would be q normal fix. I tried clearing cache and dalvik AND flashed ROMs and the problem persisted. So far, it's stayed solved. I settled in MeanROM ICS, which I highly recommend btw and have had no reboots that I didn't initiate. I just thought it wierd that a hardware issue would manifest itself that way.
Freeza's All-in-one firmware update helped me as well:http://forum.xda-developers.com/showthread.php?p=21374142#post21374142
The OP has described my experience to a T. In fact I tried all of those things in that exact order.
I have always suspected the battery but I have tried moving it around in the compartment with the phone on and can't force a reboot. Plus, when mine reboots, the screen freezes for a few seconds, which tells me it hasn't lost power and is most likely a corruption or fault of some kind.
Since upgrading the Kernel I have had less reboots, but it sill randomly happens once a week.
This has been true for 4 different ROMs now.
I have other thoughts that this is either an app crashing the kernel or my cpu can't tolerate even default speeds. None of which I have tested yet.
So friggin annoying!

Yeah, the kernel has something to do with the random reboots too. I had it with some of the dodava kernels. It would happen after unplugging from the charger. I did notice that right before, there would be touchscreen issues. Lag mostly in sipping between homescreen panels or opening apps.

thx man, how this wil work, i have random reboots on every rom especialy when phone is in my pocket, but also when stays on desk, so random shutdown/reboot, also i tryed change kernel but without success, mybe this would help, thx for advice.. cheers from croatia
If you guys are not running current firmware/radios I would check that also. I've had that cause random reboots for me in the past and it took me forever to figure it out...

Yeah, I'm running proper firmware for my ROM. That was one of the things I tried when I was figuring out wth was happening. My biggest clue was radical difference in battery level on reboots and the system ui battery reporting crashing. I knew then it wasn't the firmware.

[Q] Phone randomly turns on and off after mod

Hello all. So here is my situation.
Motorola Milestone X2
Last night I successfully rooted the phone and installed CMOD 10 using these directions
http://forum.xda-developers.com/showthread.php?t=2101633
Everything went fine. Charged the phone overnight, went for a jog this morning running both Pandora and c25k app. Absolutely no issues.
So I get to work and the phone just shuts off. Will not power back on or into fastboot. When plugged into USB, green light comes on.
After several minutes it will randomly power back on. Then after using it for a few minutes, it will just shut off again. Powering on and shutting down seems to happen randomly.
Any suggestions? Thanks in advance

Quick update. It is draining the battery. The next time it booted up I watched carefully, and the red light in the corner was flashing and it said 5% battery, even though it had a full charge just a couple of hours ago. Something must be draining it badly if it will not even run very long while plugged in. Again, any fix for this would be greatly appreciated.

Is there a reason to think that flashing to CMOD 10 actually broke the hardware? I have never had battery issues before. SBFing back I am sure would resolve the issue but then what?
And I am not talking "I used to get 12 hours, now I get 10" I am talking "I used to get 12 hours, now I get 12 minutes."
Even when plugged in, if I use it very much, it will die. Surely this is an issue of the phone incorrectly reporting the battery levels. I ran the battery calibration app (not at 100% charge since I cannot seem to get it that high) and it seemed to have no effect.
When I try to have the OS boot into recovery to try clearing the battery data, I just get an icon that look like the little android guy standing in front of a caution sign.

cyanogen 10 has issues on our phone. plain and simple. also check the battery stats and see whats running. i had an issue once with facebook running 99% of the time consuming way too many resources. id sbf and try again from stock. if theres still issues try running cm9 it runs nicely and its my daily driver.

cm9 is a bit better in quite a few aspects. i would try it over cm10. for battery life alone. i have stayed on it the longest now, surpassing eclipse, which used to be my favorite. :good:
---------- Post added at 12:15 AM ---------- Previous post was at 12:13 AM ----------
battery life on cm10 is absolutely horrible. it will never be anything close to stock, and you will be lucky if you can get it to last you a whole day. even when working properly.

Not necessarily, I've gone two days with 3g radio on but with minimal use on cm10 it really just depends on the hardware variations. Just like how two phones of the same model over clock differently because of minor flaws and variations durring manufacturing.
Sent from my Nexus 7 using XDA Premium HD app
So I was finally able to get it to charge to 100% and then used the battery calibration app.
I could not tell immediately if that did anything, but it seems to be holding its charge today. Guess we will see how it does over the next couple of days.
Thanks!

[Q] Phone won't turn on

Hey guys,
Last night I plugged in my LGOG right before I went to sleep. About seven hours later I woke up, woke it up to check the time, then fell back to sleep. When I woke up again a few hours later, my phone was completely dead. No lights go on when charging, nor does it go into the charging mode that happens when the phone is off but charging. The power button does nothing at all. Connecting it to a computer does nothing. I have tried two different wall chargers and a USB plug, and have tried different outlets. The phone is rooted and unlocked. I haven't put any new apps or anything on the phone recently, however I have had a slight overheating issue lately. I don't think that that's what caused the issue though, as when I woke up for the first time and woke it up, the phone was not noticeably hot, and seemed to work fine. Any ideas or suggestions?
Edit: As suddenly as it stopped working, it has started working again, about two hours later. The notification sound buzzed, my phone turned on, and usual on start things happened. However I'm still extremely worried about it. Now that it's on, I assume there's more I can do to figure out the issue- suggestions?
These phones are terribly buggy when charging/when they die, IMO. Worst Android device I've ever had in that respect.
Probably just a fluke, tbh.
Unfortunately it happened again- sent a message, put my phone away, when I tried to turn it on again nothing happened and it stopped working for five minutes.
Apologies for not mentioning this before, but I am using carbonrom, not stock. I've used it for several months with no issues, and have used the latest build for a week or two now without this issue.

Reboot into recovery and wipe cache+dalvik
Maybe the rom needs a little cleaning

Tried wiping cache and dalvik, but didn't seem to solve the issue. Then my phone started having an issue it's had once before- it turns on for a few seconds, then the screen goes grey for about a minute, then returns to being on. After returning to being on, it acts like it's just started up- ie, there's superuser grant notifications, cpu set notifications, and all sorts of other stuff I usually see on boot. It essentially rendered my phone unusable, so I restored an earlier backup. This seems to have resolved it for now, I may have to wait before updating carbon again.

Either you have a bad phone (possible, LG seems to have some QC issues based on some of the crazy reports Ive heard fm other people on this forum [Mine's fine]), or it's all the startup **** that you have going.
Do you usually let it discharge to below 5%?
that's a stupid idea with any device, and seems to be especially damaging to our LGOG.

Have mine 2months been careful not to let the battery shut down on its own but thirds past Monday my car charger weren't bad and the phone shut down. Would not except a charge after that. Went to att and they sent me to a service center. They could not charge it either. They replaced it, now making sure my external battery backup its always charged. Do not want to do that again.

That sounds like that could actually be the issue. On the previous iteration of carbon I almost never allowed it to go below about 10%. However the new update seemed to be harsher on battery life and it slipped into the 1% range several times...
same thing happened to me running root box with no tweaks or anything. I woke up and the phone was off, been that way for two days now. it wasn't on the charger so its definitely possible that it died. I actually found this thread because I could've sworn there was a report of someone who had to do a battery pull. I'm thinking that's my only option now.

Moto Z update ruined phone

Ok I've had the Moto Z for a while and its a great phone. Or it was until a few weeks ago. In the space of a couple of weeks a few official updates were sent to my phone and thinking nothing of it I updated as requested. The last update has seriously messed the phone up.
Problems since the update:-
- Battery drain now has the phone running out in about 10 hours. This problem seems to be intermittent, the majority of the time it happens and drains the phone quickly but not all of the time and usually its Android OS using between 25-50%. Also safe mode has no effect on the problem.
- Phone speaker stops working. Start the phone up and its working, but after a undetermined amount of time (no more than a hour or so) the speaker no longer works. If I get a call I have to turn on speaker phone to be able to hear anyone. Reset the phone and it works normally, only to happen again soon after.
- Phone charging stops working. Again start the phone and plug in the charger and it works fine. But after its charged, again after a undetermined amount of time, charge no longer works. Plug the charger in and the phone indicates its charging with the little light coming on at the top. But nothing else on the phone indicates its charging and the battery continues to drain. Reset the phone and suddenly it chargers normally. Same thing then happens again given time.
What I've tried to do about it:-
- I've tried running in safe mode, which makes no difference
- I've tried a full reset, which makes no difference
- I even unlocked the bootloader and installed a custom OS (Lineage). Thinking that obviously this will wipe out the new update from Lenovo and the phone would have to work properly again. But no, nothing changes, somehow Lenovo have done something beneath the OS that's causing these problems.
The question:-
Does anyone have any idea what could be causing this or have you at least seen these issues before?
I fail to gasp what is the purpose of the topic and I don't see a question.... If you're looking for compassion, I think the internet is the wrong place.
If you're sure that the problems is the updates, downgrade to the latest version that worked well for you. Since you've already unlocked the bootloader, try any of the variety of roms available here to verify you don't have a hardware problem.

The point of my post is obvious, I've got a issue with my phone and want to know if anyone has seen this issue with the Moto Z before and if they have any idea what may fix it. The question is right there near the end:
"Does anyone have any idea what could be causing this or have you at least seen these issues before?"

Honestly don't know how my post was unclear at all, but I've gone and tried to make it even more clear with a quick edit, hope that helps.
I have exactly the same problem. For me it occurred after updating to nougat. So fare I tried nearly everything. Disabling nearly everything to the bare minimum, custom ROMs, resetting, trying to flash only parts of the Android 6 firmware (modem, Bluetooth, DSP) since a complete downgrade is not possible, using all kinds of battery tools with a rooted device, using custom kernels... I always ended up with a constant battery drain of 3 to 8 percent per hour no matter what I did. Same in flight modus. Since under Android 6 the device didn't show this behavior I think that the problem must be somewhere in the firmware beneath the OS level. An the cruel thing is that sometimes without a reason for maybe an hour or two my moto z doesn't drain an works fine so that I do not believe in a hardware problem.
Thanks for the post. Yeah it seems like something has been changed underneath the OS. I know that sometimes memory config gets changed with newer Android operating systems (at least I think so?), but could that cause all these problems?
BTW, do you have all three of the problems I mentioned? Battery drain, sound stops working and charging stops working?
Since in this condition the Moto z is not really usable for me I switched back to my old phone and I am not using it that much as a daily device, I cannot really tell about sound or charging problems. So far I did not notice those problems.

I feel like battery life is a bit worse than with M, but I didn't experience anything as bad as you did. I switched to a custom ROM after updating to 7.0.1

I've never seen anything like it before. Its so random as well. I mean yesterday I rebooted and then charged the phone before I left for Football at 4pm. At about 11pm that night I heard the battery low sound (45% of the battery had be used by Android OS..). First thing I thought of was that usually the phone wouldn't still be making sounds by now. Since as I said earlier usually the speaker stops working along with charging within a hour or so of a reboot and this had been over 7 hours without a reboot. So I tried plugging it in and it started to charge. But then when I woke up this morning again the sound was disabled and it won't charge, it just took longer for the problem to occur this time..
How can we stop asking to update to this patch?
I has already disabled this on the developer preferences but still asking every 10 minutes
Any suggest please
Mine even worst. Battery drain fast and mobile away very warm. It suddenly reboot and shown low battery. Battery drain from 50 to 3 percent in a second! Have you guy come across this?

Yep I've also had that as part of my problem, though it had only happened a few times over the course of the month so I forgot about it with all the other problems I mentioned going on.
Basically my phone would be sitting on, say 40%, and after a reboot it would start up in the single digits.
I recently tried changing to a custom kernel to see if maybe that was causing the problem (I'd already tried changing OS). But all the problems are still there using the new kernel. Think my next step should be to try to go back to a 7.0 Android version. Are there any custom Android ROMs using 7.0?
It is said that the Motorola Manager can rescuer lost data even if the data has been covered on phone , is it true ?
Just curious what came of this. My Z, unrooted, has started running crazy hot and the battery life is not good. 6-10 hours. When I connect it to my Anker PowerDrive 2 in the car, the battery actually discharges faster or I get the slow charge warning.
Hi I have exactly the same problems as the op and tried resetting to no avail.Its driving me nuts.
Short update about the massive battery drain problem: like I wrote above, in the past weeks I tried everything from custom kernels to custom roms, resetting, deleting and so on. Nothing helped. So I went back to stock and didn't use the phone the last weeks. Today I read in an other thread about bluetooth problems that a fix for the not working bluetooth was to activate flight mode, restart the phone and deactivate flight mode. So I activated flight mode, pressed the power button for 10 seconds or so until the phone restarted an deactivated flight mode. And now the absolute strangest thing happened: for the last 5 hours the phone lost 0% battery in standby with wifi and lte on. Since I did all the mentioned things above without any effect I do not understand this at all but right now I think that this could be a (temporally) fix also for the battery drain problem.
