I've had the Gorilla Gadgets 4500 mAH extended battery for about 6 months now. It's worked very well for me up until the last month. I hardly get through the day and the battery drains so quickly even while on standby. I've recently checked the battery usage and it usually says that 70-80% of my battery is being used up by my screen. Just yesterday, it said that I used 2 hours of screen time, which consumed 70% of my battery. Any reason for this happening? I should be able to get much more screen time with my phone, and it shouldn't drain as much while on standby. Not sure why it started happening all of a sudden.
