Hi Everyone

I want to start by saying sorry if this has been answered before. I couldn't find any material searching on my issue so I made this question.

I've had my Jolla 1 since 2014 and I love it. I had to retire the phone though because it just stopped charging after basically the battery died to the point of it having no power.

When I was able to charge again the phone would not charge, the notification light is a solid yellow with and without the battery in it. There is no charging icon, I cannot get the phone into any mode.

Has anyone had this issue before? If so, what is the course of action to fix if possible?

Hmm, seems you didn't search thoroughly. Closing as a duplicate question. Welcome to TJC.

My situation is quite different (solid yellow notifcation) and not blinking red. Mine also shows this light when there is no battery in the device. I cannot even turn it on after a full 4 hours after charging. This is a different problem to the one outlined in your answer.

  • yellow light when trying to turn on with cable : battery isn't responding (missing, dead or bad contact) and the Jolla cannot boot (it needs at least a bit of power coming from the battery).

Dead battery

In your case, given the age of the battery, I strongly suspect your battery eventually died of old age (degraded to the point of not being able to hold charge).

You'll need to buy a replacement battery (JuBaTec has one specific for Jolla whose built-in BMS has a firmware compatible with the Jolla and, e.g., reports exact temperature, unlike when fooling around with sort-of compatible-ish HTC batteries)

Bad battery contact

Other thing to watch out for, in case of yellow light : check if the pins make correct contact with the battery:

  • one might have a bent pin (very gently un-bend the pin)
  • a stuck spring that doesn't maintain the pin flush against the battery (needs gentle pulling to get unstuck)
  • broken spring (put something elastic or ruberry behind the pin to push it against the battery)
  • corrosion either on the pin or on the battery terminals (be careful not to short the terminals while cleaning the battery)

No yellow light

If the light does not turn yellow when phone refuses to charge or turn on :

  • the problem might be a dirty or broken (unsoldered) micro-USB connector.

I added a comment before but it got deleted for some reason. It seems I have a hardware fault with the battery connector and it is movable up and down on the mainboard. My phone is slightly warped so I am putting this down to the problem. I got it working in the end by applying pressure to the phone. I recommend, if you have the same problem to request a repair, which will cost money.

you mean that the battery pin connector got de-soldered frim the main board?

or that the pins themselves got broken?

(anyway replacing the pins would be a possiefix, as you say).

I think the connector has come loose from the mainboard. I've pushed it back on now somehow. It moved up and down
