S3- Inconsistent battery life

[buggirl30]

Hello everyone,

I've had the S3 for several months now and have noticed a strange phenomenon; some days I have great battery life (>18h with over an hour of screen time), and other days it is terrible! e.g. see screen shots below.

I am not doing anything complicated, the only apps I run are gmail, cbc news and facebook. Does anyone have any ideas what alters my battery life so drastically from day to day?

Are you in the same location on both the good days and bad days? In your screen shots above, it looks you had a pretty week cellular signal during the entire time, which will really affect battery life (negatively). The other thing I see is that you had WiFi turned all the entire time but aren't connected to WiFi when the screen shots were taken. When WiFi is on, it will keep looking for a WiFi AP to connect to, which also drains battery.
