BATTERY BLUNDERS
There are some other big reasons why your battery may be struggling.
If you've recently bought the phone, then that may be the simple explanation.
Samsung explained: "In the first few days after purchase, users usually activate many applications and set up different features. The frequency of background operation is optimised in this time.
"Battery usage time may seem shorted than on your previous device. However, this is part of the setup phase of your new phone.
Samsung charging tip – how to charge best
Here's Samsung's official advice...
To get the most out of your smartphone's battery, you'll need to charge it properly.
Most Smartphones have a lithium-ion battery that lives longer when charged regularly.
Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge.
Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity.
If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Leaving the phone connected to the charger (when the phone is completely charged) while you are using it may lower battery life if you do it repeatedly.
"Keep using the device normally; charge it when the battery drains and allow a few days for all background operations and syncing to complete. After this, your device’s battery will be at its highest potential."
Similarly, the way that you're using data can also seriously affect battery life.
