# Glossary

### 7+ days uptime
No crash, but reboot needed.

"No reboot needed for one week" means that when that device is on Stable or RC Update Channels it should work without random or the need for a hard reboot for seven days. The Devel Update channel gets daily updates so can introduce flaws to the OS more easily.

The OS is stable. Your phone will not crash for at least one week. You will not need to reboot the device in that week.

### Offline Charging
Ability to charge the battery while keeping the system turned off

If working, the Green LED will be solid

If not working, the device either gets stuck at a bootloader screen or boots Ubuntu Touch when it is plugged in to power while in a powered off state.

Being stuck at a boot screen is undesirable since it requires inconveniently rebooting the device by holding the power button for an inordinate amount of time, or worse knowing a secret button combination to reboot

### Offline Charging
