I left my phone without charging it for a while (A few months) and the battery is now completely dead. I read online that some tricks cn bring back the battery back. One of the sources mentioned that using a hair dryer can re-live the battery?? Do you think that doing that is safe given the nature (explosive nature) or these kind of batteries? Shoud i just replace the battery? How much should it cost if I am in Canada? Thank you for your help.
