Doze Mode: The easiest trick ever! - Sprint Product Ambassadors

Sprint Product Ambassador

If I played a little word association, what would be the most common words that I would apply to the term “flagship device”:


Multi-core processor

Big screen

High resolution display

Lots of memory

Great camera

Big battery


On the last item, even though the batteries in flagship devices across all OEM’s keep getting bigger, that doesn’t necessarily translate into better or longer battery life.  The devices also get more powerful, which means they just pull more juice.  In this regard, the HTC One A9 fits the model for flagship devices - bigger, better specs, powered by a pretty decent sized battery.  But there’s one big difference: MARSHMALLOW (aka Android 6.0).


Historically, we’ve seen upgrades to Android also come at a price… sometimes better power management is merely in the form of power saving modes that are activated when devices go below a certain threshold.  Sometimes more power comes from grossly enormous batteries (3000+mAH batteries in some of the phablet spaces). 


Not with Marshmallow.


And the HTC One A9 is the only device other than the current Nexus line that comes with Android 6.0 out of the box.  So how does it save battery?




To activate Doze mode, you won’t need to memorize a long list of steps, or navigate through menus, or find an obscure toggle switch somewhere.  Here’s the steps:


  1.   Make sure your phone has some power
  2.   Set the phone down, without being connected to a charger or power supply
  3.   Don’t touch it for hours




You won’t see it, except when you wake up or come back to your device later.  The savings are extraordinary.  I’ve gone from 57% to 56% over 8 hours of sleep, which is unheard of. 


The Marshmallow laden A9 automatically detects that the device is no longer in motion or in use after a certain amount of time.  Once that threshold has been crossed, the device powers down ALL non-essential operations and applications… basically putting the phone to sleep.  The ONLY thing that can get through are notifications from High Priority applications, such as phone calls, text messages, alarms, and other critical notifications.  Notifications from your favorite social media app or game won’t make it through.  They have been de-prioritized.  Additionally, Android does have some tools in place to evaluate rogue programs that flag themselves as “high priority” when in fact they are frilly and extraneous.


It’s the invisible option that we love to use, but never actually see.  It’s Doze mode, and outside of the Nexus line of devices, you can only get it on the HTC One A9.
