you should uninstall (clear data first,then uninstall) or force stop(clear cache first then force stop) unused and unusual apps, clear caches, clear RAM, optimizing battery by putting apps sleep, force stop or disable unused useless preloaded apps...samsung apps,Microsoft apps and Google apps like chrome as it consumes more Ram and background data which results in heavy battery drain,,instead use browser, browser will take less Ram..(eg..via browser under 500KB)..clear or delete useless folder or duplicate folder in file manager... don't install apps from other stores and sites, it will cause your phone damage ..if you install these apps then uninstall it..do all these thing atleast once a day for best results...change your data cable...nonstop phone use karne se bhi problem aati hai isliye phone ko 2..3 din minimum use karo....
