Hi guys, I'm really enjoying my new Lumia 640 xl. I upgraded from a Lumia 620, this month. And I'm loving it. It's a beautiful device, in the sense that it does pretty much everything that I want my phone to do for me. The only disappointing bit (a little disappointing) has been it's battery and camera performance in low light. While the battery backup that I'm getting ain't bad by any stretch of imagination (~9 hours on medium usage, I don't play games, nor do I stream stuffs online), I must say I expected it to hold better than that. As I said, I don't play games. I just use it to browse the web, eBook reading, & media consumption. Anyway, enough talk, lets get to the topic. Yesterday morning, I was checking out the battery saver app, and I saw a few abnormal readings, at least it looked abnormal to me, since I don't really know how it works and calculates those numbers. It concerned me I must say, since my phone's battery hasn't met my expectations (it's still not bad, as I said). I wonder if these figures are normal? I'm attaching the screenshots. Looking forward to the answers. Thanks in advance, and have a great day!
