(ELECTRICIANS) Is it possible that my battery lost its voltage and doesn't work...? - General Questions and Answers

So, long story short, i was using my wi-fi to download something and than suddenly i saw I had 1% battery. I run to the charger, but my mom called me, so I totally forgot about that. I was talking like 5 mins whitout problems, than my phone died. I didn't thinked about anything, went to the charger, and plugged it, but NO LED and no sign of life. I thought i just need to wait, but even after 2 weeks, it's still dead. I had custom rom which maybe didn't had protection or something.
So my question is, is it possible that my battery got "de-volted", or lost it's functional voltage (like what my phone need) and that's why my phone is dead right now ? No led activity, doesn't start, RARELYYYY!!!!! after like 3-4 days (it entered in the first day to 9008 mode on my laptop, tried qfil but didn't helped, than never worked, than I tried at my home at PC, worked for some hours, then died again, and I never tried since than)., it is heating up when charging tho (idk if battery or CPU), and IT'S ONLY VIBRATING when it's plugged and I press all 3 buttons(also the CPU is getting really warm)
tldr. my phone discharged extremely, maybe lost its voltage. WOuld adding more voltage to it fix it ?

Battery meter reads battery is low

I just got my Captivate a couple of days ago (refugee from a Tilt2). I am slowly learning about Android.
I used the Pimp My Android PDF, rooted the phone and installed Launcher Pro. I charged the battery overnight and a message was on the phone that it is fully charged. When I unplugged it, I immediately got a message that the battery is low and I should plug it in. I have plugged and unplugged it a couple of times and it is behaving like the battery needs to be charged.
Any ideas what could be causing this?
That doesn't sound good. May need to take it back and get a new one. The only other suggestion I have is i've seen some folks say you need to condition the battery meter so it reads right. Leave the phone unplugged until the battery is so low it's flashing... wear it almost all the way down. Then plug it in and charge it up till the "battery full" thing pops up. Wash, rinse repeat. I saw several folks say after a few times of that, the battery lasted a LOT longer. Maybe yours is just really confused or it's bad. If you don't want to take it back (considering all the stuff you've done to it) try charging/discharging a few days and see if it's any better.
That happened to me one time when charging through a front USB port on my computer. I think it was the 3rd day I had the phone. I no longer use the front port for charging or data exchange, and haven't seen the problem again.
After Spending the day with the charger plugged in, it seems to be OK now. Maybe it was something I did. I will be keeping an eye on it for a while. Thanks for your responses.

Time off battery keeps resetting

Ok so I pulled my phone off the charger at 9:50am (it's 7:47pm now) and it says that it's been 2 hours and 12 minutes since my phone has been off the charger. earlier in the day it said 8 hours. Now I know for a fact I haven't plugged it into a charger. Is there something else I could be doing to reset the time on it?
In my experience, rebooting your phone, or turning it off can also reset the battery thing. Just curious to know why would you be annoyed by this, unless you are doing a battery test I don't see a problem about this at all. anyway, that's just my take..
ya I'm trying to see how long my phone can live off the battery. I do tend to reboot my phone once in a while; depending on what cool mod comes out. I will have to see if I can go a whole battery cycle without rebooting.

[Q] Battery problems

I hope I am in the right forum for this...
Lately my two year old tf700t won't stay on for more than 10 mins at a time. I have the dock and both parts say more than 100% charged.
Due to my device being out of warranty and thinking something was wrong with my stock asus rom. I downgraded the rom, rooted it, unlocked and tried several different roms.
My tablet is still turning off even though it says it is 100% charged.
Is my problem a bad battery? I think it has discharged "fully" (to where it warns me) maybe 10 times in the two years i've had it in the dock. It has almost always been plugged in or lightly used around the house. It has never been drained and recharged repeatedly to the point that I would have thought it to be worn out by now.
When I've had batteries go previously, they just drain fast from 100% to 0%. Both batteries are at 100% and it won't stay on but maybe 10 minutes unplugged. When I plug it in, it takes about 5-10 mins before it turns back on again. Meanwhile, the led by the power button blinks orange like the battery is dead. When it turns back on, it tells me I'm fully charged. grr
Does anyone know what is going on? Is there a way to test the battery or is there some chip inside the thing that needs to be reset or something.

It sounds like that you have a calibrations issue with your device. When your device is shut off by itself, you should leave it unplug about a day. Then recharge your device after a day of depletion and hope that it will solve your problem, good luck...:fingers-crossed:
Mhhhh - "almost always plugged in"?
Not the best use for these batteries. 2 years of that could have killed it.... And then - may not have anything to do with it if the battery went bad. 2 years is not an unreasonable life expectancy for a battery for a portable device.
In addition to LMK's suggestion, you could try this:
Let it die and then sit for a day unplugged.
Connect it via USB to your PC and let it trickle charge for 8+ hours (charging indicator will not even come on). Make sure your PC doesn't shut down or go into sleep mode during that time.
It should be charged enough to boot it. Check if it made a difference.

[Q] Battery dead or just drained?

Hey folks,
I'm sitting here with a very stylish paperweight. Can't charge it. No LED, not even the blinking red one. Just nothing.
Here is what happened:
My phone started to get pretty hot, so I decided to turn it off, just for safety. It had around 90% battery left at this time. When I turned it back on an hour later, the battery percentage was at about 18-19%. I used the phone as usual. No strange behavior, no sign of malfunction. After using it for quite a bit, the phone shut down as expected. The battery percentage fell in an usual matter. It went off normally.
Now, when I try to charge it, it doesn't seem to show any vital signs.
Here is what I tried:
- charging it for 2 hours with HTC Wallcharger, also tried out 2 other chargers
- Power + VOL UP
- Power + VOL DOWN
- both with a bright light pointed at the sensor
Still nothing. Connecting it to PC won't do anything good atm.
Is the battery dead, or is it just terribly drained? Did I even manage to fry the MB? Is there anything I could do?
Turning it in for warranty repair won't be an option, since it's (you guessed it) rooted and therefore unlocked. I flashed CM11 nightly about a week ago, had Codename Lungo before.
This is quite a bummer. I hope, you good people might be able to help me.
Thanks in advance,

Battery/Phone Shutting Down

Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
