I haven't had any battery issues until recently. It began about a week ago, went to work with 100% battery, checked my phone 30 minutes later to find the "phone will shut down soon" notification, and it was displaying 0% battery. I tried to restart it, but it still showed 0%. I did a battery pull for about 10 minutes, put the battery back in and it was still displaying 0%. I then plugged it into the charger and walked away. I came back 15 minutes later and saw it was charging and was at 10%. I came back and checked it after another 15 minutes and it was at 100%.
This was very strange but the battery did last me the rest of the day without any problems so I thought it may have been a onetime thing. It has yet to happen again, but since this event my battery has been terrible and I cannot seem to figure out why.
Every night I place my pre3 on my touchstone and pull it off every morning around 7am with 100% battery. I then go to either school or work and somehow the battery manages to drain to 10-15% by 4pm. I am a moderate user; I make a few calls each day, both emails are set to check once every hour, Facebook notifications are turned off, etc. I do check twitter once every hour or so, and web browse as necessary.
The only thing which may be a factor to this problem is the bing-bong affect I get when charging on the touchstone. When my pre3 is charged to 100% on my touchstone it will begin making the bing-bong sounds, the sound which it makes when you place it on the touchstone, over and over again. This does not always occur, but it seems to have been reduced when the pre3 is placed horizontally on the touchstone.
Does anyone have an idea?
