I bought the Alcatel OneTouch XL from Metro PCS in late September 2017. I had issues connecting to WiFi and had to use up my 4G data every month. Now, the original charger won't charge unless held a certain way. I bought a new USB cord but now it's only charging up to 89%. It still says it's charging but won't move past that percentage. I'm scared to do a factory reset on it and have it not fix the issue. I have a lot of information tied to this phone that I don't want to lose. Help?
