I have the BLU Vivo XL2 for about 2 years now. About 2 months ago it started shutting down with 62% battery life remaining. I will attempt to do anything on the phone and it flashes the message Shutting down battery low. It starts shutting down then shows battery life at 0%. Now, all of a sudden it is doing that with 98% battery life. This is annoying as I was trying to reply to a text message and as soon as I touch any key it shuts down. Supposedly now they make these phone with non user replaceable batteries, which I think is totally wrong as you now can't have a backup spare as I do with the earlier Blu Vivo phone. What is the remedy? I am not one of these people that want to keep upgrading or changing phones. Just having a good phone that works and lasts for a good while would be nice. What is the solution to my phone issue?
