Battey shows "Unknown" and always at 0% - Nexus 5 Q&A, Help & Troubleshooting

HI,
Looking for some help to get my nexus 5 working. The phones battery indicator is always at 0% not matter what I’ve tried (I’ve played youtube for like 3 hrs so I know there is juice in the battery)
[*]Whats wrong :
The phone battery indicator is always showing that it needs to be charged.
The phone battery indicator is always at 0%.
Settings -> Battery shows battery as “Unknown”
When powered on the screen does not show anything (you can tell its on cuz it connects to the computer. The battery cable has to be disconnected and reconnected as mentioned below to get the screen and phone working.)
Things done with no results
Swapped batteries from a working nexus.
Reinstalled stock ROM (L)
Left to charge overnight.
Cleaned cache from Recovery Mode
Used app to recalibrate the battery
The phone itself will boot up with a blank screen. I have to unplug the battery connector and then plug in the power USB. At this point it only shows the battery with flash. Its on for some seconds and the reboots over and over again.
I get it to work by connecting back the battery to the main board during one of the loops. (Sometimes holding the power +Volume up to get to the google display and then connecting)
Any help ??

When you installed L did you use the Google flash all bat file?

Yes ..I ran the flash-all.bat
The phone itself was in Kit Kat when I got it with this issue. I tried it with L to see if the issue would go away.

Other than flashing 4.4.4 clean...with wipes and seeing how it is...it could be a hardware issue unfortunately.

You've discovered the holy grail of infinite battery usage? I'm not seeing any issue here. JK, it's probably a bug in the preview software as can be expected.

Could be a bad battery as well.

already tried that as well.
The phone boots up to a blank screen. Only way to see anything on the screen is to unplug and replug the battery wire. Then everythings normal up until you have to restart.

I am on the same page. My Nexus is showing same results. I have also replaced the battery with a new one. Only one thing different in mine, I started noticing signal drops then the radio completely started to went off. Now the battery is at 0% always whenever I get it to boot that is. Otherwise it's blank with vibrations.
A fix is in great need. Also, I have tried multiple ROMs right now I am on the latest L Build.
Can you replace your flex cable with a working Nexus and write the results? I think it might fix it from the hardware side. Where I live, the flex cable isn't available! :-/

Motorola XT 720 Start up problems

Why won't my XT720 start up?
When it is connected to my charger, the four action keys light up. Despite leaving it to charge overnight, it appears that the battery isn't charging. The phone won't start while it is charging, neither when connected to the mains or to my car power supply.
I bought a new battery without any improvement.
When I access the bootloader screen it says there is too little power in the battery to program the phone.
The phone is not recognised by my computer when connected.
The phone is running Froyo 2.2. with Dexter rom.
I would be very grateful for any suggestions......apart from binning the phone!
Thanks!
I think the phone likes to selfboot with too little charge. See if you can shut it down cleanly so it won't autoboot. It's annoying but you may have to watch it very carefully to catch it when it's trying to boot because it will drain itself back to death very quickly.

Hi Oakham, do you have any update to your case? I have the same problem now.
Yesterday, I noticed the battery bar went down to orange region (about 30%?). I plugged it to the wall for about an hour (the charging symbol showed up). Later I found out that the battery bar did not move (still stuck at orange region). Later the night, I tried to charge again (the bar was red at about 15% or less). The charging symbol showed up. Later I checked, the battery bar did not improve but declined. The phone eventually went out of battery and turned itself off.
I tried to continue to charge using both the wall outlet and PC USB. No luck. I could not even power up the phone now. Did you manage to resolve your case? Anyone got the same problem and found the solution?
I thought about buying a new battery to try, but then I saw your post, so I hesitated.
Thanks.

I've had this problem. Watching the phone closely while charging and pulling the battery whenever it starts to boot works. After about the fourth time doing this I got a battery charger from amazon for ~$5 because it's gently loving annoying.

Thanks for your advice.
So when you first bumped into this problem, how did you get it back to boot up?
I followed your advice to watch it while it's charging. When I saw the motorola logo showed up, I pulled the battery. Then I plugged it back and let it charged for some more time. Then I tried to power up the phone. The motorola logo came on and then the big battery symbol came on saying it's 100% full (but i knew it's not). Later, those 4 soft touch button lid on. This cycle repeated. And I'm clueless.
Please let me know the steps you took to recover your phone.
Thanks.

Once you get into the system use 'power off' from the menu. It won't autoboot then and you can leave it in the wall overnight. I think. A voodoo doll may work, too. It can be really frustrating, but I've been able to get out of it every time so far. Like I said, I got sick of this game and found a battery charger for pretty cheap.

Try deleting batterystats.bin and doing what M said.. can you get to open recovery and charge from there?
I also had the 'M' logo screen, stuck on-screen when the charger was connected. There is a post which suggests, for this, 'Pull battery.2) Insert battery and hit power button;3) As soon as you hit the power button, hold the volume up button down until the unboxing logo comes up.'
As my phone is still under warranty, I sent it back to see if there is a physical problem. I'll try the above suggested solution when my phone comes back from 'Motorola', whether or not it is repaired by them! I've also bought a battery charger for the phone's BP6X battery from e-Bay (£9.50, including another battery.)At least I will then know that a battery is fully charged before I try fixes.
Thanks for the other posts/replies!

In my experience OR drains faster than it can charge.
Sent from my XT720 using XDA Premium App
Damn!
I had about the same. Battery got drained down from 80% to 5%. Then the screen for "please plug in for charging" appeared. Some moments later the phone went dark and now I can't get it to work again. It doesn't react on the power button. Even when plugged in the charging-symbol doesn't appear. I can't turn it on. Sucks!
Any ideas?
My phone has been repaired by Motorola, under warranty, and returned after four days. Accompanying report is brief: 'Software update and screening'. Seems to be working fine.......just like a brand new phone!
This morning i find myself in the same situation. My phone have the soft keys iluminated but it didint work.OMG... what happend durring the night.So i tried to boot the phone but nothing happend,and after reading tje post on the problem i have tried to remove the battery and put`it back, tryed anothe reboot, and holdind the buttons power+vol up. Nothing worked. But when i have tried the combination power + vol up + cammera shutter and plugged the cable. at first nothing happend. but after i have relesed the buttons the logo apeared and started charging. after that i powerd on my phone normaly
My phone does that everytime it charging and I remove the plug when it's in sleep mode. I have to remove the battery and it's power on normally.

[Q]HTC One M8 Battery Not Communicating/Exclamation Point Icon

Hello Everyone,
So I am in a bit of a dilemma, I am fixing a screen on my HTC One M8, I thought I had the phone fixed and ready to go, everything worked perfectly except when I plugged in the phone to a charger on the screen the phone said charging however in the upper screen where the battery icon is there was an exclamation point over the battery logo. So I used the phone normally (again everything was perfect) until the phone naturally died. So I thought I would try again, I plugged it into a charger and the phone blinked on and showed the battery at 0%, the orange charging light came on, everything seemed normal. However about 5 seconds later the orange light started blinking and the 0% battery logo was replaced by a battery with an exclamation point over it. I took the phone apart again and made sure everything was connected properly. I am just wracking my brain because the battery was fine previously, and obviously the charging port was working (because the phone was turning on and recognizing that it had been connected to a charger) and the phone worked fine and discharged at a normal rate after fixing it. However I cannot get the battery to recognize that it is being connected to a power supply and charge up it seems. I just do not get it, any insight to this issue would be much appreciated! Thank you all!

Probably not what you want to hear but it probably needs opened back up. Sounds like part of the battery connection is loose or severed.

Hello, thanks for the reply. I actually have it apart now, and there is only one place where the battery connects to the phone, and since the battery was working (the phone was powered on) I assume it was connected properly however I do not know for sure. This is really annoying!
Same thing for me
I had my screen replaced by UbreakIfix and had a terrible experience, so bad that they refused to fix my phone when the screen broke again. I replaced my screen and the phone works and recognizes when the charger is plugged in but I have the same issues. Gray battery icon with exclamation and a flashing orange LED when plugged in. The charge has shown 27% and 33% but it won't charge. I tried wipe partition cache, factory reset, battery Calibration app, and the battery data wipe (holding power,volume up/down for 2 minutes) Whats left? I'm on a Verizon M8 running lollipop 5.0.1

Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot

Battery dead, not charging, stuck on "low battery screen", bootloops with forceboot
Hello people, this is my very first post on xda, even though I've been lurking around for about a year. The community has helped me a lot, I'd like to thank you all for that.
Back on topic though! My error seems to be very similar to the one here.
I was watching some YouTube, battery sitting on a respectable 85%, when it suddenly shut off. Not the usual "shutting down for low battery" kind of shutting down, it was istantaneous, more like the battery was unplugged from the phone. Which is clearly impossible. I tried to boot it using the power button to no avail. I connected it to the charger, and the "the battery is too low" screen popped up. I left it at that for about 45 minutes, then unplugged from the charger and tried to boot. No success. The battery didn't even charge; the charger should be is fully working.
So I tried leaving it plugged to the charger and force boot the phone via volume down and power button; it attempted to boot, but stopped midway through, bootlooping until I unplug it, at that point it shuts off again.
The loop goes like this: OnePlus white logo (normal when you boot), radioactive kernel loading, reboot and repeat. That happens, again, until I unplug it from the charger. Then it shuts off.
EDIT: If I try to get into bootloader instead (volume up + power), after about 8 seconds of me pressing the buttons the screen just shuts off and doesn't react to any more presses (even while plugged). If I unplug and replug it to the charger, I'm back to square one (low battery, please charge).
PC doesn't recognize it. It makes the "the battery is low" screen pop up, but nothing else.
Here's some phone information in case you need them.
Phone info:
Rom: NucleaRom 1.3 (+ Radioactive kernel which comes with it) got it from here
Xposed modules: Youtube Background Playback, AdAway
Root: Yes
Thanks in advance everyone.
I doubt it would be software related if it does it even when in bootloader. It could be the problem I had with my nexus 7 a few times. I needed to charge it like all day for it to even turn on. Either that or faulty phone/bad battery. I hope it's just dead

Hello there, thanks for taking the time to reply. Yesterday I worked all day to try and make sense of the problem. I could have just bought another phone but I'm fairly attached to this one so I went deep.
I was fairly sure (like you) that it couldn't be a software problem, so I looked at the logic board of the phone; turns out (correct my poor technical wording) the bracket (connector?) for the battery on the logic board was coming off from the motherboard itself (the battery was indeed attached to the bracket, the bracket was just coming off of the board). What I did was just reposition the bracket and pushed it down with a bit of force on the board, then replugged the battery in the newly restored battery plug, and tried my luck. It booted! Back at its original 75%-ish.
My only guess would be that due to a fall the bracket got misplaced, but stayed close enough for it to still make contact and never actually shut down, until yesterday. That was... Quite an interesting ride.
Thanks for replying, it was indeed a "faulty phone", but I just couldn't leave it at that without trying
I'm glad it worked out for ya
Not work at all ...
My phone its show the logo on charging or low charge but its stuck for this for while full battary is empty... When I plagued in charger the same show charging logo with indicator but not charging its suck on that logo to .......then I charged the battary externally then put the battary try to open its show only a (powered by android log ) stuck on this ......I cant go any recovery modes ..fast boot mods...

Any other idea to solve this

N5 won't boot - Battery change

Hey there.
I'm in trouble with my old Nexus 5. As the battery was becoming less and less powerful, I decided to change it ; and so I did ! Get a new one on Amazon, and installed it.
But now, my Nexus 5 refuse to boot. Even when I put the old battery back. I didn't damage anything, all the connexions seem fine, but the N5 refuse to boot (even Recovery Mode). I also try to keep the Power Button on for 30 seconds, or even bang it, but nothing. With the 2 batteries, same result.
When I put the battery off and charge the N5, the screen does turn on ! The battery logo with the lightning sign appears for a few seconds, then it turns off. And on again, and off.
If in this situation (N5 plugged and battery off) I connect the battery (just a simple connector), I have the charging screen (battery icon fulfilling). But then when I tried to boot it, nothing. The screen just turns off and nothing happens. Even the first screen does'nt show up again.
I am really stuck with this issue as I don't know what to do ! Both batteries give me the same result. The old one is supposed to be charged (at least 50%) but nothing happens..
Could the new battery have damaged the phone ?
If you can help me on this one, I would really appreciate it..
Cheers !
When you connect the phone to a computer, is it detected at all? Maybe it is semi-bricked?
New battery could be doa, happened to me before. Also always fully charge new batteries first or you risk making them unable to charge fully or at all.

[Q] Reviving the (possibly) dead battery

Hey guys,
I've got a Google Pixel phone today and it's having a major problem. Battery won't charge, at all. Here's what I did:
1. Checked and cleaned the USB-C port
2. Checked with 2 chargers (A normal USB 2.0 type charger and a LG G6 fast charger)
3. Tested it with 2 USB-C cables. One is from the LG G6, the other one is the original that came with the phone.
4. Tried charging it using the laptop USB ports (3.0)
5. Ran a battery tester which said the battery was alright (an apk)
Android version running: 8.1.0 with Feb. security patch
The seller also said that the microphone and possibly the loudspeaker don't work. I would love to charge the phone and try the Android P BETA program on it, see if it solves anything.
I've ordered a new battery from Sweden (possibly not original, but I've read that it's alright)
Any tips?
Thanks!
Edit: The phone indicates that the battery is charging (both when it's shutdown and plugged in). The battery is at 1% now and the phone shuts down immediately - won't power-up at all.
I have a similar issue with a Pixel I bought refurbished (might just return it) - but the battery won't charge past 75%; got up to 84% one time, though. Even plugged in, once the battery gets to its 'max', the percentage will actually go down a little, to around 70% (if it stays plugged in at >70% then it usually goes down, with screen off). I also noticed mine doesn't seem to charge at all when powered off (probably a big warning sign) and also sometimes won't charge until booted up and unlocked (sucks to pick up your phone that's been plugged in a couple hours to see 4% battery with the charging indicator on the status bar says the phone is charging....).
It WILL charge if it gets booted into (TWRP) recovery - so, if your phone stays on while connected to laptop, try booting into bootloader and fastboot boot twrp-latest.img (easy to find thread for that, or just go TWRP.me website and find it there).
If that doesn't work (locked bootloader, etc.), try charging it while in the stock recovery, but I don't think it'll give you an indicator. If all those fail to give it a charge try charging inside bootloader, plug and unplug a few times, make sure USB connectors are clean. Good luck with the replacement battery, screen/digitizer can easily get messed up during dissasembly...
Edit: noticed you said won't power on at all, if you can't even get to bootloader (vol down+power with phone off) then battery or USB assembly is probably no good. Does LED flash red on the top of phone?

Hey, thanks for the tips.
I unfortunately tried all of that before it wouldn't boot up anymore, so no luck there. Also, no indicator at the top, battery is probably alright, might be a software issue or something, but can't tell since I can't update it to Android P or atleast downgrade it. I guess I'll have to wait for the battery to arrive and then try it like that. Hopefully that works.
