Re: why is my battery life draining so fast on my lumia 535
Hmm, that depends on what you're doing with your phone. If you use it for browsing under mobile data, for gaming, for navigation, for photography, for photo editing, for video calls and for mobile calls, then not much can really be expected out of the battery life.
Hence, we would need more details in order to potentially help you. What activities do you do with your phone and how long? What is the quality of your cellular signal? Are you using Wi-Fi for browsing (if you're browsing)?
etc.
