OnePlus One powers off during reboot
-
Sometimes my OnePlus One powers off while rebooting. Hoping somebody has seen this before and knows what to do. I only played with it for a few minutes as an Android device (Cyanogen, technically!), so I don't know what the hardware/stability was like before UT.
After I first installed UT to it (16.04/stable) on March 12th, it powered off before it finished its very first UT bootup. Battery was well charged and power was constantly available by USB. It wouldn't turn on until I used Volume + Power buttons, then seemed fine.
I transferred my primary SIM to it and have been using it as my daily driver since March 21st. (Hooray!) Sometimes it loses mobile signal and I have to toggle Flight Mode off/on to get it back, sometimes it doesn't come back until I reboot. (Reading the UBports Forum here, this seems 'normal' for the OnePlus One.)
I installed OTA-25 when it was offered on March 30th. After the 'installing update' screen, it rebooted, and got to the Ubuntu Touch loading screen with the background and the five dots. The second dot turned white, then it powered off. It did not want to turn back on easily. I think I had to HOLD the Power button to make it boot. Then it seemed fine.
Today (April 1st - but this is not a prank!) it lost mobile signal AND I couldn't use internet over wifi. (It was a 'new' wifi network for this device, but one I have used many times before with other devices. Wifi Settings said it was connected, even though the Wifi Indicator In that top strip was 'empty'/no signal. Internet was working for other devices at this particular time). Toggling Flight Mode did not fix it, so I used the Power button to select Restart from the menu. It powered off while the 1+ splashscreen was up, and would not turn on. Thought maybe I had drained the battery... Brought it home and put it on to charge, and it didn't even wake to show it was charging. Indicator LED was dead. Left it for a few hours and still would not power up. I used Volume + Power, then it went to Recovery mode. I looked at some of the logs but didn't see any clues. I used the Recovery menu to restart, and then it was fine. Indicator LED came back (white - still charging) and I saw the battery got up to 94% when I thought it wasn't even taking charge.
I am thinking I might go back and reinstall completely from the UBports Installer over USB. Is there anything else I should check before I do this? I have had Android devices power off from overheating, and I am confident that is not the cause here.

@prophanetes Have you ever changed the battery, bearing in mind the device is 9 years old?

@MrT10001 I have not changed the battery. I will check if the previous owner did... He was not the original owner either, so I don't know its history. It doesn't power off unexpectedly any other time. The battery life seems pretty good, and I can see from the chart in Battery Settings it only got down to ~30% today before I recharged it.

@prophanetes I am checking out the symptoms on my OPO's (more than 1 and I know I have replaced the battery on at least 2).....
Edit, on my latest acquired device, low and behold, gets to the second dot on the Ubuntu splash screen and shutdown.
Hold the power button and force a restart and it boots up fine. Battery is 100%.
This was a clean new install using the 0.9.7-beta installer and stable 16.04 (Xenial) OTA-25.
This may be a bug.
If it happens again, plug in the power and see if it kicks it back to life.
Edit: On this OTA-25 device, I do not know the battery history but it has fallen to 77% from 100% in less than 3 hours

It sounds like the same issue I have too - since the update my phone has been dead: I described my symptoms in my own thread:
https://forums.ubports.com/topic/8821/latest-os-update-killed-my-phone
I didn't watch the screen to see the dots during the update (busy making dinner for the kids), but the other power related symptoms sound identical, I just didn't have the described issues with wifi (well, nothing outside of the usual issues!)
Cheers, Scott

Okay, feeling a little silly as I look back on this. I think now these symptoms are less about my particular piece of hardware and are actually 'normal'.
- I get the sense that not all devices will automatically go through a full first boot after install without some assistance from the user with hardware buttons.
- The wifi experience was probably my own fault. The next time I tried connecting to the same network, I still had no internet access. I made it 'forget' the network, then reconnected, and then it worked without issue. I guess I had just entered the wifi password incorrectly the first time, but had believed because the Wifi Settings said I was Connected that I was 'all the way through', so the password must have been correct. I just assumed if you got the password wrong, you'd automatically be disconnected.
- I see now that OTA-25 itself is implicated in boot problems for many different models. Scary the first time it happens, but not a worry now I know it is 'normal', how to get through it, and that a fix is coming.

@prophanetes Welcome to life as we know it... yes, UT can be a little fiddly and a little finicky in some ways but we love it anyway. It's got quirks and personality.
