battery voltage low

Hi:
I have a HTC sensation 4G. I really like the phone. However, about 3-4 months ago, my phone suddenly switched off. When I restarted my phone, it got stuck on the HTC logo and wouldn't go further and switch off. It would start again, show the white screen with the HTC logo and switch on again. It wouldn't go any further and kept doing so in a loop. I thought there could be 2 possible reasons for the same: 1.) software issue or 2.) Hardware issue. I was pretty sure it was not a software issue as I had not made any changes in the software. I took it to a HTC repair center. The repair charges they were asking were freakingly high (300$!!). I didn't get it repaired from them. However, they gave me the exact reason of the problem. They said that it was a hardware issue and often happens with the phones when battery of the phone is removed while the phone is running. If this is done multiple times, such an issue can arise. I had done it multiple times before the phone had stopped working. I then got the phone repaired from another shop paying a third of the price. He didn't give any guarantee if the phone works. But the phone started working after the repair.
Very recently though, I was using my camera and as soon as the flash came on, the flash light got stuck. The phone was, however, working. But I couldn't get the flash to switch off. So I thought of restarting my phone. The phone switched off and when it turned on, it had the same problem. It is stuck in a loop on the HTC logo screen. I think this could be a software problem. What can i do to repair it?
Another thing I want to mention is that I am unable to go even in the recovery. When I try to go in to the recovery, it switches off and shows the HTC screen again. On one occasion when I tried to go into recovery from the boot screen, it showed a message that the battery voltage is low, please change the battery immediately. So i thought it is a battery problem and I looked up on the internet to find a solution. Somewhere I read that sometimes the gold plated contact points on the battery get scratched and corrosion happens. One solution was to clean the corrosion and try again. I did but didn't work. Also, when I try to charge the phone (because the battery voltage is low), even if the phone is switched off, its starts up again automatically without pressing the power button. Then it keeps going in the loop.
I don't know what the problem exactly is. Do i need to change the battery? I am running official HTC ICS ROM. Please help me with a solution.
It will be of great help. Thank you!!

[Q] Some really weird problem over here.

Once, i was halfway using whatsapp then phone turned off automatically, when I turn it back on i was able to boot up past the bootscreen until i got this: Refer to Picture 003.jpg
Then I did a complete reset via CWM. I even installed CNA 3.6.6 (I was using 3.5.0 before this)
Still no avail, do I've decided to flash back to 4.0.4 to see whether things are working out or not.
I did it via fastboot.
Same thing.
What could be the problem?
Do take note that even though in the picture I'm booting it up in safe mode but still no avail for normal mode.
And, when I'm charging my phone with the power switched off I'm getting this: Refer to Picture 004.jpg
Supposedly it's a battery icon that indicates charging activity but I'm getting a battery icon with (blinking) exclamation mark.
What's wrong?

Gonna try it soon as soon as my friend is with me. Anyways, the picture I've attached shows the shutting down popup.
When it first occured(and for the next few times)it's without the popup and i can't even pull down my notifications window. BUT the 4 buttons worked. they responded by vibrating.

warning! TL; DR post about what happened to my phone.
I've left my phone (accidentally) under heavy rain for almost an hour.
By the time I got my phone back it's still working, but with a (kinda) faulty loudspeaker.
Others went a-okay.
I turned off and let it stay put for everything inside to dry up then charge. Realized that I can't charge at all. I can't even connect to computer or whatnot. So I brought it to a service center. They told me it's mobo issue and I've decided not to fix it (cause my warranty's over)
That day when I brought it back from service center, miraculously I can charge my phone! was happy at first then I kept on charging. Then story continues as first post.

same thing here!

i bought my nexus from a man for 25$ because it wasnt able to charge and when u turned it on it just went stuck on the motion starting picture.
so i went to a technician and he told me to buy the usb port , i found the original port for nexus s on ebay, so he fixed it...
since then i am able to charge it (with a exclamation sign if its off) and i have even intalled every rom i have found here, via odin/fastboot/CWM, etc. but nothing... so it keeps on stucked on the starting picture, sometimes just SOMETIMES it went up like yours, *going up and saying/showing Android System icon, batterymetter on the upper part of the screen, middle screen; saying power off, shutting down, after some secs, vibrates and goes OFF.
only with slimbeam i got that behavior always turn it on.
p.s. the USB port was unable because phone have been wet (from the other owner hands)...

one thing, make sure the battery contact points are clean i know its dumb but it could help

Still the same.

Nexus S i9023 Android 4.1.2 Update
Yesterday i got OTA update 4.1.2 in my Nexus S i9023 in India. But after restarting the system for installation for some reason the update was not done. After hard booting the device when it logs on, it was showing 4.1.1. But when i am checking whether any system update is there, it is showing no update. How to get it again ????

[Q] Motorola RAZR HD XT925 Doesn't Start (Blinking Green LED)

Hello. I have problems with my device, a Motorola Razr xt925 HD. It doesn't start, it just keeps the green led blinking when connected to wall charger, and when I plug the USB, makes a sound of a new device detected but only for a few seconds then it makes a sound of an unplugged device, and so on. It doesn't respond to any combination of buttons. I let it charging overnight, even though the battery was nearly full before this happened. Don't know if this is relevant but before this happened, I was going to flash stock Retail Brazil firmware by fastboot and got a flash failure. I turned it off and then it wouldn't turn on again. I never had this happened, I had problems but I always solved them all. Not this time hopefully you guys can help me or tell me what it could be, because I doubt it was the battery. I leave you a video showing my case.

i dont know for certain but the only time i see that green light is when battery is ou and i put it to chrge. Could your phone be in apfastboot and can t charge. It is a bit of a tough situation to troubleshoot.
Did you try keys combo to put it in fastboot, and test it by flashing
or maybe use rsd lite see if it shows you device connected? maybe then you can flash stock
i am sure there are other possibilities, let s hear from you

There's no way to enter in Fastboot by key combos and RSD lite doesn't show my device :/ maybe I need a factory cable, just in case that the battery is empty. I need more suggestions please

me paso lo mismo
did you find any solution?

im having this problem after i start using KK 4.4.2 seems like the phone go to sleeping mood by it self while my screen is locked so i have to keep clicking at power and volume up and down to restart the device now im looking for an update or a fix for this problem, another problem is the device WIFI do not catch my house signal while im away 10 feet from the house the software have bugs

I've been using CM 11 (KK 4.4.4) with no issues. This is a flash problem or maybe the battery. My phone is still dead btw I see that two more people are having the same problem here... we need a solution please.

i think your your device is dead.
this exact thing happened to me.
it happened on september, i was forced to get a new device.
i love this phone but it was dead.
i hope a fix comes through i would like to have it back

I ll take one of your hand, I need parts if interested

Any update with this? Did you try with a factory cable?

I'm going through the same thing , I read the other day that and the driver installed and nothing more .
keep trying to revive my device.

I'm going through the same thing. When I plug it into my pc , under device manager it shows "Human Interface Device" then it unmounts itself then remounts itself then unmounts. Over and over..... I've even replaced the battery.

I was running stock rom with just root, phone was working great. phone rebooted, screen never came back on but when i connect it to my computer it sees it in adb..........
Any advice would be great.
Thank you

This thread for the droid Ultra might interest you: http://forum.xda-developers.com/droid-ultra/general/droid-ultra-maxx-brick-recovery-t2830806
There is some discussion of the Razr HD in this thread. It looks like someone with an unlocked device would need to dd their bootloader partition for this method to work.

A few years later .... Any solution? rsrsrs

any update on this scenario?
i have this situation too and the time could give us an answer, i am searching again, i took my device to some 'phone repair stores' and in less than 5 minutes they told me that the phone was dead, but i have my last doubts

Just to add an update here
I ended up with the Green light only and blank screen after trying to fix a battery issue, despite getting a number of batteries my phone wasn't accepting the batteries.
I remembered a battery issue a long while back, so went to reflash my phone to see if it resolved it.
I ended up with the green light and blank screen and no matter what buttons, it would just make a noise then keep rebooting.
I ended up using the Unbrick bat file.
RSD Lite was briefly showing a Medfield device of something starting with Med, but since the phone kept rebooting I couldn't reflash it again.
I did the Pwr and Vol down and as soon as I saw the device, I clicked the UnBrick bat and it managed to get my Moto logo up.
I then booted to Fastboot mode and reflashed and my phone is back,
See this link for the UnBrick, but when you do it, you have to be fast to catch it while the device is seen, otherwise the phone reboots after 4s or soo.

[Completed] A story about my freakishly hard bricked LG G2 F320L. Help needed!!

This is my story that happened with my LG G2
I recently purchased a LG G2 F320L, a refurbished one, from aliexpress(I think this was the biggest mistake of all)
I got the phone, I started using it, used it for 20 minutes and just installed antutu benchmark and ran the app and started the benchmark.
Firstly, I'd like to mention that the phone just got warm, just like other phones, during the test. While the multicore performance test was going on, the phone turned off, all of a sudden (Battery was as low as 9% when I started antutu benchmark). I thought that, it was because the battery was too low to run a benchmark app and turned on the phone back and waited, it just showed me the LG logo for 5 seconds, powered off, ended up with a bootloop. :crying:
I thought that the OS or the bootloader got corrupted and stuck and also thought that I could easily fix it by flashing boot.img or the original .kdz using LG flashtool.
I connected the phone to the PC, it was charging from 9% (That means, low battery isn't the reason for this problem). I waited until it charged till 25% and tried turning the phone on again, but, the same bootloop happened again. I downloaded the .kdz file for my exact model and prepared to flash it using LG flash tool. Unfortunately, the phone came out of download mode (Whilst the flashing was going on) and started with the bootloop again. I really got scared cause the flashing was interrupted indefinitely. I didn't know what to do and I just googled how to enter factory reset mode and I finally entered factory reset mode and chose to reset the phone completely. But, it has happened for a while and continued with the same kind of beat-up (But I was able to enter the factory reset mode later on, though) I was pretty much scared at this time and I gave the phone to one of my friends. I showed him the factory reset mode that was still working, but not useful, and I tried resetting 3 to 4 times but couldn't come out of the bootloop. But, suddenly I couldn't enter factory reset mode and the bootloop became pretty much faster that before (Just showed me the LG logo for 3 seconds and rebooted with the same bootloop). Now, no factory reset mode, download mode, and no charging either.
I got to know that it was a really serious hard brick that has ever happened to one's phone!
I handed over the phone to another one of my friends and he dismantled the phone and tried something, then connected to the computer and the computer detected the phone and QHUSB mode was saying 'Searching Windows update' with a loading symbol. He just stopped it there and told me to take it to a good service center (An expert, of course), and he also told me that I was supposed to ask him, to make the QHUSB mode work.
But, after he gave me the phone back, the bootloop was still happening, just like before, but, instead of LG logo, it was showing some bluish white lines on the 2/4 on the screen.
I haven't got time to go to a service center till date, as they might cost me more than I invested on my phone.
This is really serious problem and I need to enter the QHUSB mode and I need to flash the stock firmware cleanly. Please anyone give some time to read this thread and help me out in this situation. AGAIN, I have used the phone for like, just 20 minutes when it was in a working condition.
So, I request any experts to help me out, suggest me the solutions.
Sorry for my bad English, though.
Thanks in advance.

Poco X3 NFC - Can't access bootloader, fastboot or system (bootloop)

Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])

Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.

Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway

Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...

Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.

CaptainFedora, did you solve the problem? I have the same issue...

Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.

Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
