Last week I got a notice that my Samsung Captivate Glide could be updated to ICS 4.0. I had some problems upgrading initially, but eventually discovered that you can't use any old micro USB cable, the Samsung one was needed.
Anyway, since upgrading, my battery life has been terrible. It takes forever to charge up and discharges almost immediately. I don't think I could go more than a couple hours without having to recharge it. It also gets hot when charging or if I'm using the phone.
Also, in the "active applications" area, I am almost continously seeing my email app in "red". For example, right now it's reading RAM 31.63MB, CPU 68.34%.
I have the screen brightness turned down (more than before) and the GPS off. I use the Bluetooth while driving to use my ear piece. The wifi is on while I'm home because I do use it regularly...and I was able to do so before the upgrade and still have acceptible battery life.
Do I have a problem, or is this what "enhanced performance" looks like?
