Re: how to stop my note3 from restarting
If it's about as old as mine (about 15 months) and you've mistreated the battery (too cold, too hot, letting it discharge almost all the way a lot), it could be at its life's end by now. (A badly mistreated battery will hardly last 6 months.) The good news is that a package of 2 Anker batteries and a charger (so you charge the one in the phone and the one outside the phone at the same time) is about $25. (Look on Amazon for Note 3 battery. Anker is white with a blue label, so scan and find the picture of 2 of them with a charger. One battery with no charger is about $13, so the charger is basically free with 2 batteries.)
