How old is the battery? About 2.5 yrs old.
If you have been using the phone regularly on a daily basis the battery could be starting to short out.

Does Android let you see this data? $ grep ^ /sys/class/power_supply/BAT0/{charge_full,charge_full_design} /sys/class/power_supply/BAT0/charge_full:3533000 /sys/class/power_supply/BAT0/charge_full_design:4030000 That shows that currently "100% charge" is 3.5kAh, but when it was new "100% charge" was 4.0kAh. i.e. it's capacity is down about one-eighth. The same workload will give me 17½h instead of 20h. $coworker had a much bigger difference - about 50% drop. PS: "kAh" might be completely wrong, I suck at units.
