[Bug 1317860] Re: [system] the phone should switch itself off before completely draining battery

 

Specification updated.
<https://wiki.ubuntu.com/Power?action=diff&rev2=74&rev1=72>

** Changed in: indicator-power
       Status: Incomplete => Triaged

** No longer affects: indicator-power

** Changed in: indicator-power (Ubuntu)
       Status: Incomplete => Triaged

** Changed in: ubuntu-ux
       Status: Triaged => Fix Committed

** Description changed:

  the phone should switch itself off at around ~5% remaining battery.
  
  This is to preserve a little battery for use cases such as:
  
  * turn it back on once or twice for urgent short phone calls
  * prevent the battery from going into a state where it can't be charged any more
  * have enough power to turn itself on again and trigger an alarm
  
  --------------------------------
  Desired resolution
  
  The following actions should take place as the phone/tablet runs out of battery:
  at 10% - Notification battery under 10%
  at 5% - Notification saying battery level is critical, will shutdown soon.
- at 1-2% - Shell fades out, animation fades in (same as startup animation), phone initiates full shutdown. 
+ at 1-2% - Shell fades out, animation fades in (same as startup animation), phone initiates full shutdown.
  
  The notification should be a clickable notification with the tap action
  mapped to dismiss.

+ (PC) or power off (phone/tablet) if both of these things are true: *
+ there is less than 2% battery remaining * there has been more than 3%
+ battery remaining at some point since the last time the device
+ hibernated or powered off."
