Lollipop: Toggling "Battery saver" when not charging

[Elias Pinto]

My Nexus 4 just received Lollipop this week.

Any N4 owner knows the battery is the Achilles heel of this phone.

Lollipop (finally) introduced a built in "Battery saver" mode that can extend the battery a SURPRISING long time.

Owners of phones with bad batteries (like me) need a Tasker Action that turns on Battery Saver so it can be enabled way before the built in 5 or 15%, or it can be enabled whenever it is not charging.

Yes there are background data sync considerations to be aware of, but having a dead phone battery outweighs the costs.

Is this possible with the Lollipop API?

Thanks gurus.

If not then use autoinput plugin.

I did look through the current Tasker options and actions. Nothing there to enable "Battery Saver".

Idk about the autoinput plugin, I'll look into it.

But I have a hunch that Tasker may need to have that type of action added.

It's not possible because Lollipop doesn't provide any API to do it. Maybe it would be possible with root access and maybe you could ask for example to secure settings plugin forum for this feature, I'm sure it will add support for it but only for root however.

[Marta Hintz]

Again that is why you use auto input when you don't have root and you need a button pushed that shows on a screen.

Awesome. Thanks Marta and John. Hope you had a great Thanksgiving.

There is a better answer.

Get the Secure Settings app and use its plugin within a task. Action > Device Setting > global > low_power
Value of 1 is on, 0 is off. The System UI recognizes the change immediately.

It's a premium feature, before buying I'd like to know do you need root for this?
For activating battery saving mode, Value should be set to 1 , and to turn it off to 0?
Also using Nexus 4 stock lollipop, not rooted

Writing a global setting can be easily done using java code inside Tasker without any plugin.

[Darijo Gospić]

Could you please instruct us how to do it?

Writing a global setting can be easily done using java code inside Tasker without any plugin.

It needs the WRITE_SECURE_SETTINGS permission, which isn't granted to a normal app
I'm pretty sure.

It was a general suggestion about a general setting, so I don't know if it's applicable in this case. I don't know the specific setting because I don't use lollipop, when I'll do the upgrade I'll see. However I think using root there isn't any problem (maybe).

Thanks so much for this! I'm guessing setting it to 0 disables it? that seemed to disable it. The strange thing is though when you enable this automatically via secure settings and then go to check battery stats it still shows as balanced under the battery info. maybe i checked too fast? I checked right away. Obviously its on battery saver mode because the orange nav bar. 

[Darijo Gospić]

You used Secure settings to turn it on? or java scripts?
