Hey everyone, I figured a thread with a consolidated guide on the D3 would be in order. There's great info in this forum, but it's all spread through different threads and posts. Please, if I miss something of use, let me know so I can share it with everyone! Saving Battery: ~This is a global phone, so to save battery life, you should go to settings > wireless and networks > Mobile Networks > Network Mode > and choose CDMA ~For adjustment of your battery savings, go to settings > battery and data manager > battery mode, from there you can choose from the following options: maximum battery saver (max savings, least auto updates), nighttime saver (option I use, switches to battery saver mode at night), performance mode (no restrictions on syncing/no battery saving), and a customizable battery saver. `credit to IzelTokatl for this tip Limiting Data Usage: ~Go to settings > battery and data manager > data saver > from here you can select or unselect the data saver.
