[Q] My Nexus 5 rebooted itself 5 times today? - Nexus 5 Q&A, Help & Troubleshooting

This is the first time this has happened. Basically the screen will just turn black randomly and the Google image pops up for a couple seconds before staying off. The first 3 times it happened I was able to turn it back on by just holding the power button. After that, however, it got stuck in a boot cycle until I plugged it into a charger and tried. So far with the charger plugged in it hasn't turned off yet.
I've attached a screenshot of my battery status. It seems the battery disappeared for a few hours?

Does your battery smell like sulphur?

Sounds like a stuck power button unfortunately. Quite common.
I'd say try flashing stock firmware again with fastboot.... But if it reboots while flashing, you'll be in more trouble.

Let it sit in bootloader mode awhile... See if it reboots or anything. If not, you could try flashing stock firmware. But hopefully it doesn't shutdown mid-install.... That wouldn't be good.

Hmm. Major Issue Need expert help!

Hi all. I have years of rooting under my belt but this is the first Samsung phone i've owned and I've got quite an issue. I was playing a game and the phone just shut off on me. I went to restart it and nothing. Did a battery pull, i felt it vibrate like it was trying to turn on and still nothing. So I tried to boot into cwm using volume up/down and power and the Samsung splash screen flashes for a split second and then shuts off and the phone just vibrates like it's going to turn on but won't do it.
So I tried battery pulls, holding power down, and now when I plug it into the computer it vibrates every two seconds but won't turn on. What's the deal this seems like a major hardware malfunction and Odin/CWM none of that stuff is usable because it just won't boot into anything.
So last resort do you guys have any suggestions i'm all ears :-(
I've had this a few times before... I forget which one exactly but either vol up + power button...or vol down + power button gets you to download mode and then you can flash the softbrick fix.
or if you do manage to get to CWM, you'll need some quick fingers to get to the "install zip" option before it reboots. once in there you're good to flash your ROM.
or, get a USB jig to get to download mode and flash soft brick fix.

False alarm, apparently there is a battery bug reported on other forums. My phone had read 100% for quite awhile and I was digging the battery life but apparently i was over zealous. The meter was reading 100% but the battery was draining and the phone died. It wouldn't fire up until i left it on the charger for awhile. Very odd, guess I will delete this post and research this battery issue... unless someone else knows more about it
I have the same battery issue, but only when I use my car charger. When I take it off the car charger, it will read 100% till I reboot. Only after reboot will it start reading the battery state correctly. I DO NOT have this issue with the house charger...... Strange.
you guys after charging for 100% go to cwm and format battery status this will probably resolve ur issue.

[Q] Let battery die after flashing new rom, now it wont charge

Ok guys, I'm in a predicament, I flashed the latest AOKP build 3 (clean flash) flashed IMOv.16 cache/dalvik/permissions and everything worked great. This was around 2pm. I spent the rest of the day just messing around with settings getting it how I liked it. even after several reboots. Now my battery dies around 11:45pm so I plug it up and it vibrates once, the charge screen shows for a second but the charging icon doesnt spin and then cuts off. tried it for about 30 minutes in the wall, 30 minutes from usb from computer, now its been in the wall for about an hour, if I unplug and plug it the phone does nothing, but if I pull the battery put it back in and plug it up to either power source the charge screen shows for about a second and then cuts off, but nothing happens after that any suggestions? has this happened to anyone else? what should I do?
Ok im not sure why that happened, but I fixed it. I pulled the battery, put it back in and instantly help VOL down + Home + Power and I got it tothe screen before Odin. So I was going to flash stock, but I figured if i can get into Odin I can get into recovery so I pressed down to restart phone instead of up to enter odin mode and it restarted and booted up, with a significant charge on it! Phew thought I had done something bad! :victory: My blood pressure is returning to normal now, but why did that happen in the first place? Will it happen again if my battery dies?

Outstanding work! My blood pressure is down now too.

[Q] Screen won't turn on.

I've been running the latest CM10 M release for a couple weeks now. Today I upgraded to the latest modems. Everything was working great for a few hours when my phone randomly shut off and now won't turn back on.
I've tried pulling the battery and charging. Can't ever see anything on the screen although it does vibrate sometimes when I hold the power button. LED will turn on when charging.
Any ideas or suggestions?
See if you're able to boot straight into download or recovery, thus will show intact boot and recovery systems.
One other test, pull battery and with phone off plug into your PC if it shows a red light its likely hard bricked.
I had the unfortunate experience of flashing wrong kernel and bricked my phone was not going to recovery or download. However if you can get to these then it may be a soft brick and restore with odin

Once my phone got stuck because I flashed a new recovery that wasn't compatible with my phone so each time I tried to boot into recovery or tried to turn on the phone nothing would happen. The only thing that got my phone working again was to go into download mode (Odin) by holding power, volume down and home buttona and than canceling it. from there the Rom started working again. I don't know if it will help in your case but you can always try.
That was a strange experience. Left it plugged in for a few hours. Came back, and was able to boot normally... although the battery was extremely low despite being plugged in for a few hours. No problems since then.
Congrats =)
Seems like disaster was avoided.

Do you know what percent your phone turned off at? Around what percent? Was it 23-25%?

Nexus 5 boot looping after complete discharge

UK Nexus 5, recently OTA'd to 4.4.3, totally stock.
Forgot to put the phone on charge last night, found it dead this morning. Put it on charge for a bit, had to take it off charge to use it only for it to die shortly later. Plugged a usb cable in to charge, phone would loop and not boot properly. It would get to either the Google logo or the Nexus animation. Held vol- and the power button but couldn;t select 'Power Off' in time from the boot menu as it would just reboot itself.
Got home this evening, plugged in the proper charger. It looped for a while, but now I've got it to boot where I could choose to Power Off. It's now on charge where it started booting/looping again once, but is now sat charging properly. I'm not sure if all this weirdness is caused by the battery being drained completely. I'm suspicious of the power button. I banged the phone around the button in case it was stuck and blew around the edges just before it started stopping looping.
Any insight welcome.
Thanks

Thanks[/QUOTE]it's not the power button. I have had this happen to, I thought it was a bug in TWRP, it usually only happens when the battery is low, or wait a minute no it doesn't happen when the battery is low for me it happens when the phone gets warm because I've been flashing something over and over in TWRP.usually I leave it in TWRP for a little bit then when I hit power of it actually stays off as long as I'm not charging it. I am dictating this using voice to text hence the mistakes and forgiveness backspace delete backspace

Something I actually learned from paintball, a low battery makes technology go nuts. My Nexus 5 bootlooped with a low battery. It also said it stopped charging and basically acted like an overdramatic child with no cookies. After an hour on charge everything was good to go.

Nexus 5 won't go into bootloader/recovery

So my phone was working with no issues since I first bought it at launch. Today, after being on in the morning. It shuts down by itself, goes into boot animation but never gets back into the main screen. Tried to charge it for a few hours to see if the battery was the issue, but the "charging battery icon" does not even pop up when I plug in the charger.
I tried to get into the bootloader/recovery. At random times, I might be able to get in to the "start" screen, choose boot into recovery mode but it turns off as soon as I choose it.
So not sure if the battery is the issue?
Phone is rooted and using a custom ROM.
Thanks for any help before I go and replace the battery.
