The following is the battery siginal indicator strength as seen in settings->Power Management->Battery Usage

Tap on graph is see history details.

The Mobile Network Siginal will be one of the following where 'yellow' is bad and green is good.

Even with applications 'closed', many will continue to run in the background.

These applications, like news feeds, email and social media will continually 'wake' the system up to check netwrok/data/status updates. If these applications are poorly written/set up, they can quickly drain a battery.

Also having Bluetooth, GPS and location services always on, also use battery.

Just a few things to consider.
