Hi! Technically, there are ways for this to be possible. But is not as easy as it sounds.
May I know the reason of your question? It this just for curiosity?
Do you feel your phone has been hacked?
i feel that my battery life isn’t as good as it use to be, there are times when I’m not on my phone at all and I’ll be at 50/60% for battery. There are times where apps will freeze/crash. also, it will take my phone awhile to load something or won’t load at all.
Allright, couple of questions to help us determine what's going on:
Is the device software up to date?
When did it start doing these type of things?
Have you performed any troubleshooting steps to the phone?
In previous conversations you mentioned the battery being drained faster than usual and that apps take longer than usual to load. The battery issue could be that the battery is depreciating or something in the system is draining much power than usual. Have you updated your device lately? What type of device do you have?
you should be able to go into your settings and locate battery..then see what all has been using up the battery..
keep in mind that if your signal isnt as stellar as usual THAT can drain the battery as well..by chance did this start right around the time you received a update for your phone? and which update is your phone currently on?
