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!!

u have ur answer, its a hardware problem, "sounds" like the audio chip is bad, new mobo required

problem solved ( voodoo magic??? )
So first of all i would like to tell you how my problem started.
First of all, my phone was rooted with kinguser.
I was answering calls and in most cases i couldn't hear anybody. That day my i727 was out of power due the empty battery. I left it to charge over the night and in the morning when i tried to power it on, only at&t logo was on the screen and mobile freeze on that point. I didn't want to hard reset because of all the contacts in phone, so i tried to power on about 100 times. I lost patience and hard reset it. After that same problem persisted, phone freezes on at&t logo. I was on a trip so i tried many more times - pull battery, power on, press power button long time, power on, and on and on. After about hour of trying my phone started but again without sound. I tried to plug in phones but it didn't help. tried to play music, restart, install new players, set the sound level nothing helped.
I pulled out my old htc wildfire for use, and took i727 for taking pictures and things like that. I bought bluetooth earphone, and that solved problem, but i wasn't satisfied. I bought new speaker ( about 4 bucks ) and installed it. Unfortunately that didn't solved problem.
I was using my i727 for about 2 months only for camera and games. In that time i tried to put stock firmware to solve problem. That also didn't help. I read on this forum how to put custom rom and i tried. I am not so expirienced so i had many problems, i didn't manage to do that in first place. Tried with odin, CM10 and few custom roms, but failed every time. I thought that 40 bucks it too much for new mobo.
Two days ago i downloaded android 5.1.1, twrp 2.780 and gpapps. i followed steps and manage to install android 5.1.1 on my i727. On first power on android logo ( red green and yellow ball on startup ) looped in infinity. I reset phone with power button and on second time, android was updating. Phone started and new android 5.1.1 was up. First i tried if there was sound, but with no luck. Day after i installed some game, and after few hours of playing, phone turned off because battery was empty. i pluged charger, power on phone and went out. 5 hours later phone was still on startup logo bubbling. I tried to take battery, and power on, again infinite loop on android logo. i tried to reset with power on button, but on power on infinite loop again. I didn't want to lose my save in game so i tried to reset, and try, and try, and after many attempts finnaly phone started, and updates was applying. I waited for updates to finis, and phone started. i put my phone on table, and in few seconds viber ring. i read the message , and after that i realised that my phone had sound again! today is second day with sound. Still don't know how that worked out...
I hope that helps

two days after, my battery went out, and after recharging, there was no soun again

Sony Xperia X5 won`t start after the last OTA update..???

Hi yall and Happy New 2017 to all comrades
Gentleman,
I have an annoying issue with my Xperia Z5. Yesterday I finally agreed to let the automatic update commence after post-poning the damn thing for a week. Started at 48% of battery, the phone switched of and underwent with the system update installation as usual. Nothing extraordinary throughout the the whole process - the progress bar filled up all the way to 100% and the Sony attempted a reboot. Unluckly the reboot did not happen. Blank black screen with no signs of life in it whatsoever.. Holding down the Power Button doesn`t change anything. Holding down the Power Button + Volume up / Volume down (any kind of combinations with these three) doesn`t work as well. Sticking the charger in is the only thing that makes a little difference where the LED will start flashing red periodically , but not holding solid red light as it would have been charging. Holding down the Power Button until the charger is plugged makes the led solid red, but as soon as I let go on the button the light vanishes too..
This has been well frustrating already. I tried to hook it up to Sony Companion (their mumbo-jumbo soft for sony devices~pc) but no life doctor, I read no pulls.
My phone is not rooted and was carrying the stock Android Marshmallow (don`t even now the version).
I used to root every single device I had since 2012 with that including HTC Sensation XE, HTC HD2 convertion from Windows to Android, Samsung Galaxy S2, Samsung Galaxy S3. With this beauty i decided to take the other way of keeping things simple and just for the sake of my social life and my miss, as I get pretty addicted once it comes to custom ROMs and such. Put in other words - although I don`t want to go there I would if needed to get my phone back to life, as I start work back tomorrow and half of my job is receiving 60+ calls and emails and i`m kinda f*ck#d without my smartphone. Unfortunately I do not own any other device which would cover me for the time being nor friend that would help.. - im friendless
Anybody ? Resurrection ideas plleaaaaasseeee

Is it enter fastboot or flashmode?
If no,what happened if you connect it to computer.

Same thing happened to me when upgrading from .253 to .305 last October...
I was at 60% and left the phone charging while it updated and then the phone just died.
No way to boot, red LED when plugged in to charge and not detected by any computers, so no possibility to fastboot...
Also fully stock, but makes me miss my old rooted HTC M7...
Contacted Sony and was told that I would have to ship it to Singapore and pay both ways and for repairs (which would cost the same as a new Z5), so i just bought a new E6603 for my sister and took her E6653. Sony rep also told me not to update from OTA, but to use Xperia Companion. Seriously?!To provide OTA's but we're not supposed to use the?! I ran CM Nightlies on my M7 for over a year and never had any issues with OTA builds/dirty flashes!
Probably won't be buying another Sony phone (for myself or any friends or relatives) after this. You kill my phone with your update and then tell me that you wont cover the repair/replacement?!

Ok, I`m willing to try that. Any chance you could advise me to solid working flashtool and a thread with a step by step bootloader unlocking + flash + root guidance ?

Try first if your phone can goes to flashmod/fastboot
If your pc detect your phone as QHUSB_DLOAD than it's a hardbrick and a motherboard replacement is needed, next time NEVER use ota on a rooted/unlocked bootloader
What i can say is that yourdevie is fota bricked
Edit: similar case :https://forum.xda-developers.com/showthread.php?t=1126358

If your phone can enter fastboot/flashmod this is no big deal, just flash a new firmware the one you want with flashtool but by excess of prudence check all case in wipe section before flashing, now you'll be good to go, you'll just have to set all you thinks back, but I guess you prefere this to a dead phone

XZ premium froze, now won't turn on

Hey guys,
Have been using the xz premium (single sim edition) with unlocked bootloader and first version of Oreo ROM installed. The device froze the other day, then went blank. It won't respond to anything whatsoever (fastboot or flashmode) and I have pulled the battery leads and put them back again.
Any suggestions? I've had 0 water exposure and have no idea why this would be happening. Thanks in advance (=

You mean you opened up the device? The first thing you shouldve tried was holding the power button and volume up till it vibrates, if it wouldve vibrated. Since you say you have pulled the battery though that could only lead to either a dead battery or a faulty motherboard/hard brick somehow. Since you did nothing and the device just froze all on its own I cant say a dead battery would cause this as if it were the battery the device wouldve most likely powered off not froze.
Another thing that could be tried is to try power it on using just the charger. Also trying that without thw battery connected might help. If none of that works then the chances are its time for a motherboard replacement. Personally I wouldve just confirmed its death then sent it off to Sony for replacement. If the handset was completely dead and couldnt be recognised by PC then there wouldve been no way for Sony to verify that the bootloader was unlocked. Since you opened it to pull the battery that also would void the warranty. No matter how well you were to put it back together im sure there would be a way for Sony to verify if its been cracked open or not unfortunately.
I did a bootloader relock on my Xperia Z when I water damaged it and they never knew it had been unlocked and I got a replacement handset baring in mind that the device could be used just that issues occured with the volume buttons.
The most I can suggest is above. Either try the button combinations and charger methods, or considered a new device or motherboard replacement. Also if possible try the battery in another device if able to otherwise not much can be said without replacing. I hope this helps abit.

One plus is a fraud company its hardware gives up after 1 year,,,this is bul****

Hey dude
Well strange i would contact oneplus about this should be under warranty there's no point in asking on the xda if you haven't even unlocked bootloader and clearly you aren't a user that like to fiddle with things
Cheers hope oneplus support will help you
Mine op6 works fine have it till launch no issues so i guess its stupid to call company a fraud,there's always chance that the smartphone or any electronic device will fail overtime that why you have warranty

I have posted my query here because few years back when i was using HTC ,i faced an issue and when the service centre gave up and returned my phone unfixed,one senior member from xda helped me to revive my phone and certainly that guy made my day for which i shall be forever thankful to xda forum
P.S : I am Sorry if i have hurt you in any way , i am just fed up not able to find any solution yet
I am just here trying my luck and hoping to find another life saver, Cheers ?

I've got the exact same problem. Op folks told me it's a hardware issue and they might have to replace the motherboard. But I really don't trust them

Its pretty much a hardware problem. I had the exact same problem with my OnePlus 3. I went to the official OnePlus service centre and they told me the same (to get the motherboard changed). I don't think it's worth to change the either motherboard.
I got the network IC repaired for half the price from some local mobile repair shop. See if you can do the same.

I have OP 6T and this issue started right after one of the updates, as the phone asked to reboot after an update. So, right after that update phone took 10-15 minutes to boot. Couple of days ago the was another Google Security Fix update, and that killed everything. No SIM cards, no wifi hardware... I tried fresh install, which stucks at - Wiping, Please wait. I tried to unbrick it, and I was able to reinstall official android, but still not wifi or mobile networking. they are just gone. - Does not like a hardware issue to me...

Turn off phone, remove SIM, turn on phone with no SIM, turn off, then plug in SIM and reboot again.

Most likely it's the Network IC, very common issue
You can try all the SW things first just to be safe but if nothing works then it's all that's left.

I have found a workaround which has worked 100% during last 7-8 times this issue happened. Once the no sim and wifi detect issue happens, switch off the phone, plug it into charging, let it charge in switch off mode for 2 mins and then switch it on with charging on.
It sounds like jump starting but somehow it works. Seems like network IC or something gets reset. Keeping my op6 for now with this workaround!

I too had a similar problem after getting my touch and screen replaced at OnePlus service center , while returning they told me that it's motherboard is also faulted and will work for few months at max and after I started getting the same problem as sim card not being detected and wifi unabled , but I got a temporary fix for it. The problem still persist.
The solution to this is while the phone is loading just slap the screen with palm strongly just don't break the screen , slap it repeatedly until you are asked to put the unlock code.

It's a temporary solution as the problem is in your motherboard, i even had my IC changed but nothing helped.This is the only solution, it keeps happening twice a week or even more.
