Signs that your mobile has been hacked
Significant decrease in battery life
While the battery life of a phone inevitably decreases over time, a smartphone that has been compromised by a certain type of malware may begin to show a significantly shorter lifespan. This is because a malicious software may be using the phone’s resources to scan the device and transmit information to a criminal server, reducing or draining the phone battery.
Unknown applications

This also goes for any calls, calls, text messages and emails that you’re quite sure have nothing to do with you. Hackers may be using the device to send premium rate calls or messages, or to spread malware to all of your contacts.
Increased data usage

If you find that your data usage is rapidly depleting unexpected, your phone may have been compromised by some form of malware.

If you find that apps are crashing or failing to open, this could also be a sign that malware is overloading your phone’s resources.
