at the beginning installing some heavy game or app like tik tok the battery was very bad just getting to last 10 hours when 1 day before installing it lasted 1 day and 15 hours I contacted samsung they told me it was a problem of the operating system so, I reset the device after the updates arrived (the last one a month ago), this improvement markedly improved by using it for 1 day and 15 hours, using it for 2 days 10 hours and using it only with social networks 2 days 21 hours is what lasts for me, it loads an hour and a half, I was never branded and it was always fluid I must have more than 50 apps
