Prerequisites:

• Poor battery life compared to KitKat/Lollipop.
• Overheating during light use (common with Snapdragon 801 + Marshmallow power management).
• Slow charging on non-OEM chargers.
• Limited app support – Many modern apps require Android 7.0+ (e.g., new versions of Chrome, banking apps, Microsoft Teams).
