It always seems like there's something wrong with my evo. This morning I went to pick up my evo after it was plugged in all night (like i do every night) and it was burning hot. I looked at it and it said it was 133 degrees so i unplugged it and turned it off immediately, after it cooled down I turned it back on and it was at 70% battery after it was charging all night, so it wasn't charging at all last night even though the light was on and it was showing a green full charge when I woke up. after I turned it on it was on for about 2 minutes then automatically rebooted and then was on for another 3 min and rebooted again for no reason. my phone reboots randomly alot. this happens to me a few times a day usually 2 or 3 times. sometimes while im doing something important and sometimes when the evo is int even being used.
Does anyone have any idea what my problem might be?
My evo setup is fresh 3.3, no custom kernel. ebay 3000mah battery no case or anything like that for overheating. ive been running this setup for months (just with lower fresh builds) and have random reboots. This is the first overheating issue. The only thing thats changed is I started using a .99 ebay blackberry micro usb but ive been using that for a week and never had a charging issue. my hw v is 3
I'm thinking that maybe the battery has an issue. Have you tried with the old battery? As far as the other problems that you have, it does not look good. Try reflashing, if it does not fix it then it is likely that you need your phone replaced.

Im not sure because Ive been using this battery a long time with no problem, even now I plugged in the phone and its charging fine with no problems. If it does this again tonight maybe its the battery, I was thinking maybe it was something to do with that battery being plugged in to long.

I would say it's your aftermarket battery or BB charger. Try and use the OEM accessories.

what about the rebooting issue? this was there before the aftermarket battery and charger

As I said before, try reflashing the ROM and see how it behaves. If the problem is still there AFTER a clean install then it is hardware related, if not then, well keep the ROM

Ahh lol welcome onboard! Yes I believe it's probably the charger and not the battery. $0.99? Great deal, but be careful.
I got the same over heating issue on the stock battery a day ago. It was burning hot when I woke up, and took out the battery with the ac on blast for a minute. It wasnt plugged in, so I was surprised it happened while on the stock battery. Went to my 3000mah battery from ebay, that I have never had any problems at all with.
I was running cm6 with stock kernel. Im guessing it was a freak accident, since no reboots or any after effect from the heat.
On the positive side, I was able to push down the screen due to the heat and fix my light leakage problem

That is precisely why you need to reflash so you can know for sure if it is a problem with the device itself or just a software glitch.
See if you have too many rotation options checked in cm settings. That made mine reboot a lot. Now just have 90 and no more issues...

The only external item left is the sdcard. Try another. If it still reboots, then return it for service/replacement. The low battery and heat and reboot can all be caused by a large amp draw. Install alogcat from market and look for messages indicating why. You could also use quicksysteminfo from market, and look at the dmsg's.
I have had a similar problem with my girlfriends Evo. Random reboots until it got to the point where it was just stuck rebooting. After reading this thread, I recognize battery heating as a symptom as well. I ended sending it in to HTC for warranty repair. It turned out to be a bad chip of some type. Having seen a number of threads regarding random rebooting, I wonder if there might not be a defective series of these chips. At any rate, the warranty process was quick and easy. No problems since I got the phone back. This was also an unrooted phone, so I think your ROMs are probably working correctly and it is more hardware issue.

you need to reflash bad.
There is nothing hardware related that is going to run you 100 cpu all the time.

even after I reflash The same things keep happening
I can't seem to find any information on this issue.
I charge the battery fully on my external charger and then when I put it in my Inspire it shows red with no battery charge then shuts down. When I power it on with the usb plugged in then the battery shows full and I can unplug it. If I power it off then back on it then shows empty again, even if I quick plug in the usb. I have 3 backup batteries and this happens with 2 of them. All of the batteries worked fine until this started happening. I just rebooted with the usb plugged in and when I check the battery info on my ICS rom it shows 0%, charging (AC), 21s on battery. When I unplugged the usb and refreshed the battery info it now shows 99%, not charging, 3s on battery.
Any help would be greatly appreciated, my son's Inspire does not have this issue with the same batteries that i use so it has to be related to my phone.
This happens on my phone rom, Melcheizedek v2.1 and on one of my Boot Manager roms, Lords ICS v 7.4.
Thanks!
I dont know if this will help.
Try using a different stable Gb rom. If problem persists, power off, pull the battery out, put back the same battery, power on. If it still happens, try cleaning the battery connectors. In the past week or so in either this section or the inspire 4g (either the general or Q&A) someone explained how to clean them.
Edit: does the same problem happen in recovery? My guess is yes, regardless if it's software or a hardware prob.

I will try a GB rom today. I just completely reformatted and re-installed Melchizedek - AOSP ICS booted my phone and battery shows red, no charge. Reboot with usb connected to AC and full charge shows then when i unplug still full charge. When i am in recovery it shows battery --% for a few seconds then it changes to full.
Coffee still hasn't kicked in
In recovery it shows 100%. If you stay in recovery what happens?
Same problem? It discharges and then shuts down?
Can you use the battery cover from your sons cellphone?
Do you remember what you did when you first noticed the problem?
Insight to something that happened to me a few weeks back.
I was running a Gb miui rom, I installed a mod or something the device bootlooped. Erased everything, used my backup, but then the battery would discharge insanely fast. 3-5% per minute. From 80% it went down to 65%, rebooted, then it would show 76%. Wipped everything, installed a different stable rom, no apps whatsoever, same problem. I went into recovery, same issue in recovery, erased, (this part I'm a bit foggy) I believe the same thing happened in recovery with a formatted system.
Can't remember if I installed another rom or just went back to my backup.
Powered off the cell, swapped batteries with another phone, the issue was gone.
My assumption is that by pulling out the battery it solved the problem.
In your case, you already pulled out and tried several batteries. But they work in your sons cell. However, with several batteries it is unlickly (the spelling for that just seems wrong for some reason) to be a battery (just ranting to see where my mind goes).
Still waiting to know what happens in recovery.
If it happens with different roms, Im assuming you full wiped. Especially if you are running one from the collective and lord. You probably know more than I do
Try using a different battery cover if you can, and also try booting your cell without the sd card.
Try them seperately to see if either one works.
Hope something I said works, or at least gives you ideas to try something else.
Edit: I just re-read your initial post. It happens with two out of your three batteries. That's a tough one.
Whats the difference between the batteries? Does your sons battery work on your cell?
You can disregard cleaning the connectors - probably.
Or clean the connectors on the bats and the cover. Or try your sons bat connector with those batteries.
Could you re-phrase your initial post along with everything that has happened and what you have tried?

When I boot into recovery it initially shows no charge for maybe 20 - 30 seconds and then shows full (or whatever level the battery really is). The battery level stays normal then and works perfectly fine all the while I am in recovery.
I just rebooted with the battery I was using all day, it was plugged into a usb ac at work until about 3.5 hours ago, and it rebooted with a normal battery level, I rebooted again and it was normal again. I booted this same battery in the morning and it showed no charge but now it works fine. I then rebooted with a second battery and again it booted fine with full charge. I put in a third battery, this was the one it first happened on, and it booted with no charge. I put back in the battery I had in all day and it booted with normal charge again. I checked the bad battery and the good battery and both have about 4.2 volts.
When it happened the first time it was only with 1 battery, that was about a week ago. I just got 2 new batteries in the mail and one worked fine and the second booted up showing no charge like the other one. That was 2 days ago, since then every battery seemed to do it until now, I just checked 5 batteries and only the first bad one and the one new one that was bad don't work, weird.
It seems like the bad battery screwed up something in my phone but it's hard to believe that whatever it was would survive a system format. Now it seems to be working fine...I don't like things that fix themselves...
Well, if you have the time let's try troubleshooting the issue with only the bad batteries (as long as if you believe it to be software related only).
Keep in mind that I'm trying to help figure this out, and to keep bumping this thread until someone more knowledgeable joins in.
If its software, remove the sd card, format everything. Power off, remove the battery, while the battery is out press and hold the power button (hoping the cell works something like a pc) for 30s. Then install - I don't know - any rom? Load a few basic apps you use/need. See what happens with the bad battery.
You did say the bad battery does work in another cell?

I don't believe it's software related, I reformatted and re-installed the rom I was using and still had the issue. I have been using the same rom for a while with no issues. I'll check the 'bad' batteries on my son's phone tomorrow.
Edit: Booted normal this morning again, I think I can close this issue for now. I am a bit uncomfortable with not finding the root cause but at least it ended in my favor. Thanks for your input!
You are welcome. My next step was going to be to link your issue in another thread. Good luck.

Try full wipe and reinstall ROM, if doesn't work flash another ROM. If doesn't work again, maybe it's problem whith battery controller, you would have to go to service centre

I had a similiar problem and it happened after i started playing with ICS DHD Roms. I downloaded a stock WWE sense 2 rom and flashed that. I then flashes the latest Stock WWE 2.5 Sense rom and all is still ok. Dunno if the stock flashing (through exe from PC) it was unrooted though. Fixed it but its fine now. So maybe try that.
Perhaps this may help.

Thanks for sharing my post on the Inspire forums, Teichopsia.
I'm convinced that there's something in the non-sense ROMS that doesn't get the battery charge % correctly immediately after booting. I'm having the same symptoms as the original poster is having. Two of my batteries are after market and two are HTC. The generic ones have the problem of registering 0% on reboot after swapping the batteries in. If you have them on the charger they work fine and show 100% after about 30 seconds. If you reboot with the same battery it's fine until you change to a different one. The latest ICS Rom I'm using has the problem with any reboot, even if the same battery is in. If I'm using real HTC batteries this problem doesn't manifest itself on Cyanogenmod or AOSP ROMs.
EDIT: I should clarify that the after market batteries fail on any reboot without the charger with the latest ICS ROM I'm trying, but the HTC batteries are fine.
I've had success with booting into recovery mode and wiping battery stats. This is not a permanent fix but is useful when you don't have access to a charger and need to swap batteries.
The full procedure is this: with phone off hold power and vol down, select recovery, advanced, wipe battery stats, yes, go back, reboot system now.
Bad battery I think. Ik had the same problem with a brand new, original battery.
Charged it fully with external charger, booted phone with it but showed 0% juice....
I had to boot with the charger plugged in, and then after booting it went to 100%
Send the battery back because this was not normal, recieved a new one and didn't have the problem.
btw I was on IceColdSandwich rom...
Im running ICS 4.0.4 aospX 1.0.0-MR1 on my HTC Inspire 4g with a Anker® 1600mAh Li-ion Battery For HTC Desire HD, Inspire 4G - White and had this problem initially.
The only way my phone would boot up was if it was plugged in, otherwise it would show a dead battery warning when the homescreen loaded, and then it would shutdown. If I booted it while plugged in, then disconnected the cable, then it would run off the battery just fine.
What I did to fix it was to shutdown the phone, take off the battery cover, removed the battery ( the Anker one), blew into the compartment to make sure there was nothing interfering with the connectors, wiped the battery's connectors with my finger, and then i replaced the Anker battery, pushed hard on it to make sure the connection was good, and booted the phone.
To my surprise, this actually seemed to fix the problem. Whatsmore, after I put the battery cover back in place, the phone continued to boot with no issue, meaning I did not have to push on the battery to make sure the nodes were connecting. I even shook the phone in my hand to see if this would loosen the battery connection, but it still booted fine.
I then took out the battery and replaced it to make sure it would still boot, and it did. Hope my solution works for you! Cheers!
CM is having issues on the One X with reported battery levels as well.

Hi all
I've bought 2 Desire HD batteries (1210mah IIRC) and they work just fine on their own.
I can't manage to keep alive my phone after replacing one with another (charged), though, since the phone believes the battery charge is 0%. I know this is an error, since I can always plug the phone and check with an handful of apps.
This actually means that I can't switch from a dying battery to a charged one if I don't have access to a USB socket!
If I have to guess, I'd say the phone is not deleting batterystats when I swap the batteries.
Any idea? I'm running CodefireX JB nightlies.
Have been noticing the same behavior! Would like to know if anyone knows a solution..

Actually I did found a workaround, kinda. After a first boot-automatic shutdown, this morning I booted in recovery, then I wiped batterystats (although I don't know how that could help). After a reboot it shat down again automatically, and then it worked.
I'd guess it just take some time to read the correct mV value. So basically you could leave your phone sitting in recovery for like 5 minutes and then reboot. Or, you know, just fratically reboot until it works. That's my plan anyway.
Meh.
That is a known issue with batteries other than the original HTC battery. Since I'm used to have a sensation battery, I ought to bring along portable charger whenever I can in long trips. There is no other way other than plugging it in charger or just hoping that it would boot up with a lil bit of luck.

It makes sense. I had to reboot the phone after a full charge (unrelated issue) and then it happened again. I tried my luck; after three reboots the phone got it right. It should be enough having the phone sitting in recovery mode for like 5 minutes. When it shows a valid percentage it's good to go!
This happens to me almost daily. All you have to do is restart the phone maybe twice... nothing else. I used to think i had to plug it in as well. Nope just restart it, if it shows 0 percent again it'll die, restart again, bam 100 percent.

Hi, I got a problem with my htc desire z. First, i bought this phone, like week ago, no warranty but 100% working. After few days, i noticed that battery sometimes does not charge, but after moving a cable it was ok, i tried few chargers and i appears to be usb port issue. Few days later i rooted the phone and installed custom rom. Everything was ok, but battery life was horrible - after charging up to 100% phone was up for 4-5 hours with no playing, only sms, calls and some wifi. I flashed another kernel, then yesterday flashed that rom: http://forum.xda-developers.com/showthread.php?t=2163579
But today after charging to 100% it shut down after like 4h of no use, chaged to 100% again. I unplugged the phone, run Flappy bird and screen went black. Cant boot, cant boot to recovery. When i plug in to computer, red led blinks and adb finds the device as recovery. Please help me guys :crying: I made a backup b4 flashing latest rom so i hope there something i can do.. But maybe its battery dead? Cuz as i said, aprox battery life was 3-5h on every rom, even after recalibration. Hope you can help me. :fingers-crossed:

Considering it's age, you probably need a new battery. Try an Ankers 1600mAh, it's still going great for me.

I will try getting new batery, but i think there is also problem with inphone microusb port.. cuz battery was loading properly only when i deflected the plug-in.
The anker battery is awesome and the price has come way down. You can also often find it with an external charger on the cheap through eBay as your USB port sounds cruddy
If you want to replace the port its about $5 so very cheap but it is soldered to logic board and if you aren't comfortable with fine soldering you will need to pay someone to do this, I would guess about $20
But first peek in at it as sometimes you can see a bent terminal and you can bend it back into place with a toothpick but not always
Best of luck!

Thank you so much for help.. I bought a new battery and it works :victory:
I don't know what happened, but my true friend is probably deadly ill and she's dying.
My Samsung Galaxy Tab S 10.5 after almost 3.5 years of really hard work, 8h daily of SOT, hard CPU tasks, loading battery two times a day, started to do strange random reboots.
I was installing Blue Filter app, reading big pdf and sending this PDF from Xodo to Voice Aloud reader. Tablet was connected to charger from Moto X Style, which is turbo power charger. I saw first reboot, then other and next. Entered Cwn Twrp, cleaned cache but the problem still existed. Cleaned system, internal storage and tried to flash Iron ROM again. Strange, but tablet couldn't flash Iron ROM 3.2 gauge showed 100%, almost after beginning of installing ROM. I decided to flash 4 elements repair ROM with Odin, but it didn't help. Checked erase NAND, flashed correct pit file.
Strange, but while flashing with Odin, there were no reboots, so downloading mode is working properly. But after install, reboots returned, almost after running system first time.
Maybe it depends on ROM version? I flashed 4 files of 4.4.2 with Odin, while I was on 6.0.1 earlier?
But reboots started on proper ROM.
Also, maybe charger is responsible? Moto X Style 3A charger maybe damaged memory or motherboard of my friend?
Do you think that exchanging the battery may help? My battery when it was loading frequently showed a red cross, it can be that it's damaged, but random reboots never happened to me.
I don't want to buy new device, it's really stupid for me to spend hundreds of dollars every two, there years. I believe that a device should work 5 years or longer. Maybe corporations make devices especially to die after warranty period?
Can you help me to determine what is damaged?
It was my true friend, carrying tons of books with a thin device, reading big pdfs smoothly, making notes tons of paintings, editing photos and taking photos with my Nikon D610 via USB, listening to music with A.r.i.s.e , watching photography tutorials and movies, modern Combat 4 tons of hours, notes, showing portfolio to my clients... Yes I love my small friend, can you help me to rescue it?
You can see the behaviour here
Are the reboots happening even while plugged in or only after unplugging the charging cable?
Also is the percentage reading being sporadic meaning it changes every time it shuts off?
Replacing the battery is fairly cheap and easy on this model.
Here is a guide:

Where to buy a replacement battery:
https://www.ifixit.com/Store/Parts/Samsung-Galaxy-Tab-S-8-4-Battery/IF252-014-1
If for some reason it still has the same issue after replacing battery then the battery connector needs to be looked at under microscope. It may have a loose connection to the board meaning it would need to be resoldered.
Dear Benjamen, thanks for your help. Tab reboots even if it's plugged to charger. The percentage is strange, one time it shows 40%, another time beeps and shows low power warning.
Sometimes it works 5 minutes without reboot, some times boots many times continuously.
Do you think it's battery? No EMMC error or some chip damaged on motherboard?
Download mode Odin worked good, also CWRP worked without reboots.
Maybe internal storage is damaged?
What do you think?
If it is battery I can surely exchange it like you wrote.
You can see the behaviour of tablet on YouTube I've posted above.
Have you tried to reinstall Twrp and a custom rom besides Iron Rom and doing a clean flash? Also I was thinking it might be a corrupted sd card try to remove the sd card and reboot see if that works I had a tablet once that was going bonkers cause the sd card was messed up , it might not be it but could always try it. Also make sure your on the proper boot loader for the rom you are trying to flash iron rom thread actually has a link to all the current boot loaders if i remember correctly. I do own this device and run a custom nougat rom no issues, just shooting out some ideas but you are right this is great device and should last a long time.

Sounds like battery connector has loose soldering. Take it to a reputable repair shop that does soldering and tell them to check the battery connector and see if it needs resoldering. That's how I ended up fixing it with the same symptoms that you had.
Edit: Forgot to tell you but I cant play the YouTube video, maybe the embedded video link is invalid so can you send me the youtube link?
Mine has been doing the exact same thing for a couple of days now.

Random reboots both with the charger connected and disconnected, Battery percentage is around 45% most of the time, but jumps to 0% or 100%.
I've already replaced the battery with a "new" one (about 12 months old, according to the label), but to no avail.
Any ideas? I really like this device and would not want to buy a replacement...

My SM-T800 started doing something strange like this yesterday. As I was watching Youtube and reading a news site in split screen mode, the screen suddenly went blank (it didn't shut down, but went blank at once). Before this happened, I saw a warning that my battery charge was below 15%. After powering on the tablet, my charge was 28%. I opened youtube and a web browser again, and the screen went blank within a minute. After powering on, I decided that I will not be using split screen mode again, but the screen eventually went blank. I monitored the CPU temperature and it didn't seem like it was running too warm (50ish C). I will try re-calibrating the battery (if that's even possible) and even replacing one, but if that doesn't help I guess it's time to move on to something new. Sadly, four years after the T800, nobody made a worthy replacement (the leaked Tab S4 specs look good, but they want to charge laptop prices for that).
PS: It's running the stock rooted (later unrooted) MM 6.0.1 from November 2016 with TWRP.
I re-calibrated battery and the tablet seems to be working fine so far.

Okay first of all very big thank you for your replies
my Galaxy Tab S 1 except strange reboots is also overheating when it has some tasks to do measured temperature on CPU cores is getting around 80 degrees Celsius and is going up and then tablet gets restart so I don't know if it is only the problem with battery maybe it's connected with CPU problems or other electrical problems on MotherBoard.
It's worth to mention, that I've charged the tab with charger from Moto X Style, that is Turbo Charger, with 3A, and the Tab S1 can load with 2A only.

My tablet used to have a damaged main-board that used to overheat. However, the screen did not go blank when that happened. I actually got some kind of message that said that the tablet is overheating. This was fixed after I replaced the mainboard. You can certainly try it, but these things were not cheap when I did it.
Mine also started doing this last month now it wont power on but resets till the battery is dead.
Did you get it fixed?

I'm seeing random shutdowns with no warning popup on heat but the screen area where the motherboard is sure gets hot. I replaced the battery and same result. I looked at the battery connector and looks OK, seems tight but I didn't check with a magnifying glass. Where did you source your motherboard?
Also how has everyone elese resolved this? I see people citing the problem on this old thread but I'm curioius if you found a resolution.
