Didn't see any similar thread so far so hopefully it is not a repeat of somebody else's experience. I have had my 4s for about a month. To start with, battery was far better than my 3GS but after upgrading to 5.0.1, i can easily go for a full day usage with medium to heavy usage. I definitely think 5.0.1 helped my battery.
However starting this week, i am seeing a strange behavior. It used to take about 20 min of web browsing for my phone to drop 1% in battery power. But for the last 5 days, i have been seeing it go down 1% every 5 minutes. Now here is the interesting part. If I press home+power button simultaneously to do a reset, battery usually jumps back again. For example, i did a reset at 98% battery level this morning after 10 minutes of usage. When it came back on, it was showing 100% again. Also after doing a reset, it seems that i am usually getting more juice out of my battery. Anybody else experienced it?
