How much does your battery drain overnight?
I was just trying to gauge if my phone's battery drain excessively. Just to experiment, I left my phone uncharged overnight from 100%. After 6 hours, I was down 20%, after 8 hours I was at 74% and I received around 5 messages throughout this time. Back when I had my iPhone 5, it would drain 20% overnight as well. I knew that it isn't normal, so Apple swapped it and gave me a new one that was draining at a more reasonable 5% overnight.
On a weekday, I would unplug my phone at 7:20am, turn on airplane mode in the subway, turn off airplane mode at the office and get home between 7-8 pm with around 30 - 40% left. My usage include light messaging throughout the day and browsing during lunch time. The first day with BlackBerry Protect on, I came home with only 6% battery left. But that might be due to the fact that I was testing it out at work.
Maybe an OS reload would help. How is everyone else's usage and battery drainage like?
