Charging in very long hours and battery exhausts very soon


I have Samsung Galaxy Tab 3, Model SM-T211 with Android version 4.4.2, Kernel Version 3.4.5-4496770.

I had issue with my tab was it used to take long hours to get battery charged and used to exhaust the battery within 2-3 hours. It used to turn off when the battery was 40-50% or sometimes at 60% too. I have changed the battery but it still is taking very long hours to get battery charged full. Last time I started charging at 1600hrs and it charged completely at 0900hrs in the next morning (about 25 hours). Please help me to resolve this problem.

Either the battery is not charged with a powerful charger, so it will take long to charge.

Or the device constantly runs with high CPU load, then you should use a CPU monitor App to verify that first.

Last possibility is a old or damaged battery, which then needs replacement.

I had this problem on my Galaxy tab 2 also, because a Program was constantly using up the CPU.

Thanks a lot for your quick and very helpful response. Can you please help a bit more by adding how to manage CPU load and how to verify the App.

There are several Apps to check the CPU load for Android in the PlayStore.

For example

This will show you any process that is constantly using up too much CPU (if that is the case for you)
