I tested the E6Xperience v4.2 for three weeks as my "weekend phone." Here is the data:
| Feature | Stock Belle Refresh | CFW (E6Xperience) | | :--- | :--- | :--- | | Boot time | 78 seconds | 52 seconds | | Openning Messaging | 3.2 seconds | 1.1 seconds | | Browser (web.whatsapp.com) | Crashes on load | Loads in 14 sec (Opera Mobile) | | Battery (standby) | 2.5 days | 3.5 days (undervolt tweak) | | RAM free after boot | 89 MB | 154 MB | | Keyboard lag | Occasional | Zero | Published by: Nostalgia Tech Labs Reading Time: 12
