    I own a Samsung Galaxy Tab 4 10.1 which I purchased in 2014. It's been 3 years I have been using it and this week its starting to act weird.

    Thursday, this the first day the battery acted weird. 65% charge and it started to drain to 0% easily by 30 minutes. Soon, when I turned off it and charged it was 20% - the battery was back fast charging until 75% by 30 minutes and it was stuck.

    Friday, the battery charged over the day and it was only 92%. When I turned it on, it suddenly dropped to 72%.

    Saturday, I fully charged it overnight and it was normal. Strangely at night, the normal battery was 82% by that time but by 2 hours and 10 minutes it was reduced by 39% charge. I turned off it and charged, it was 0%.

    Today, the tab was 100% full, yet today I turned it on and found out it suddenly dropped to 72%. By 45 minutes I used it, it was 57% by now.

    What is even wrong with my battery? I have no rogue apps or anything that quickly drains my battery.

    Batteries have a finite number of charge /discharge cycles, after which the chemicals degrade and the battery will eventually die.
    Replace yours before it dies at a most inopportune moment.
