Battery Life and Heating on Passport Silver Edition
Hello! I just got a second hand BlackBerry Passport Silver edition yesterday, and although the phone works flawlessly, the battery life is horrible.. and the devide heats a lot when using it. Before I got it it was used for two months and according to its previous owner the battery lasted two days and he never had a problem. But this device has been turned off without battery for 5 and a half months aprox. I've been reading a lot of forums and I see that the exagerated low battery and the heating are quite common among the passports SE. But I don't know how to solve it. I've been trying to install an update trough BlackBerry Link but there are no updates available. And honestly I don't know what to do. I don't have android apps, and when checking, there are not any apps that are consuming battery. Just the screen, the system and the "waiting mode" (modo de espera in Spain). And I have BBVE and it says the battery is in a good condition. How can I fix this..? Please help..!
pd: i don't have any screen shots right now but if I use the passport for 5 minutes it just eats a good 10% of the battery.
