I suddenly have to charge my phone every 5 or 6 hours.
@socrmom901 could be a battery issue as well as a software settings issue. The battery is easily replaced LG K7 Battery Replacement and I’d start with that after verifying that the settings are correct. For that take a look on here https://www.gogorapid.com/fix-lg-k7-batt… as well as on here https://www.hardreset.info/devices/lg/lg…
you haven’t mentioned the phone type and model . if its a removable , try to use another and see if makes a difference . if not , try to do more research on background running softwares and apps that use a significant amount of batter to function. new phones got the ability show you the batt usage by the app type and name . good luck! this is a simple prob to fix .
