    Puzzle over symptoms Motorola Smart Phone

    I am trying to repair a motorola moto g play cell phone. It suddenly went dead. I have disassembled the phone and removed the battery and motherboard. The battery appears fine it takes and holds a charge and lights a 6 volt bulb. When I measure resistance from battery + terminal to ground I get approx 1 meg ohm and reducing suggesting capacitors are being charged. If I then connect the battery( 3.8 volts) nothing appears to happen but if I then disconnect the battery the resistance from battery + terminal to ground shows a short. After about 10 mins doing nothing the short disappears !. Is this a faulty capacitor ? Which components fail in this way ? How might I identify the suspect component ?

    Thanks for any help and Happy New Year.

    Tony

          Help with trying to fix phone that is not charging (Pics inside)
          by SluggerB
          I have two TCL A30 phones.

          Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

          New Phone: Works fine, bought as a donor board to try and repair Old Phone

          My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

          new OS on a Sonim XP5s phone
          by keeney123
          To you programmers out there I want to know if it is possible to put a new OS on the Sonim XP5s phone? I only need this phone to make calls, receive calls, have a list of contacts and be able to call voice mail.
          I bought this phone new Sep.2021 as an unlock phone from a third-party seller. The phone worked fine until Jan 2022. I then had intermittent problems with the sound setting resetting itself. One of the settings, outdoor, would go to silent all by itself. When in silent mode it does not indicate a call has come in. I missed very important phone calls. All the other setting in sound...
