4) Run the security wipe.
5) Set up the phone after the security wipe to full operational status
6) Reinstall apps from Blackberry world
7) Side load Snap
8) Reinstall needed Android apps from Google Play using Snap
9) Do not attempt to install data, such as contacts from Link. Install contacts from the cloud where I keep them backed up.
After that, I never again had problems with wild battery drain.
Some can follow this procedure and some can't. If you cannot, I now recommend utilizing a non-destructive update though Sachesi. Worked perfectly for me going from 10.2.1.1925 to 10.2.1.2141 and my phone is now working better than ever. (STL100-3). Also, there was no need to reinstall apps or data, all of it was already there after finishing the install.
Choose your method. Either should work if done carefully.
