Today I took an accounting of my usage of the Thunderbolt. The battery drain is unacceptable and I'm guessing that something is causing a problem that can be remedied, even though the battery life remains paltry. In short - I listened to music for 90 minutes while using the phone to rearrange apps, read a few emails, etc. for about 50 minutes of that time, all while having airplane mode on. Drained the battery from 100 to 65%. Not very good at all. A few short video recordings and pictures drained the battery another 15%. I was at a dinner and the phone was at 50% and didn't use it at all except to play a 4 minute high definition video clip that was on the card. By the end of dinner 2 hours later, the battery was down to 10%. I have nothing knew on the phone that I didn't have on the Incredible. I'm experiencing some very strange quick drains that are unexplainable. Others are too. Some of you are getting better battery life, nothing that I deem acceptable but better than this. I'm going to be speaking with someone tomorrow that I know who has technical background and hopefully will have some answers. Doubtful at this point who knows. Verizon Wireless also instructed me to take the phone into a store to have it checked - as if that will make any difference. They will probably give me a new battery and tell me to see what happens.
