What is the most extreme battery saver method out there? I don't need anything (location, data, nothing) except phone calls when my screen is off. I know of greenify but even that's not good enough

I basically want to turn my android phone into a Nokia 3310 as soon as the screen turns off?

This is not just a question about app suggestion. I'm wondering if it's even possible on android. Google play services would probably not allow this sort of thing.

PS: I have a OnePlus 3 running Nougat.

  • Is your device rooted? – beeshyams Jul 13 '17 at 8:20
  • Try Macrodroid automation app. Trigger : Screen off; 1. Action : Battery Saver on 2. Launch shortcut of Greenify hibernate now. That way you hibernate plus launch battery saver mode. When if your device is not rooted , there is a workaround using adb for action 1 – beeshyams Jul 13 '17 at 8:26
  • What version of Android do you have? – Grimoire Jul 13 '17 at 10:01
  • Yes, rooted. Running Nougat. Willing to even install a custom ROM for this. – kBisla Jul 13 '17 at 11:29
  • @beeshyams I tried a similar (same?) thing with tasker. Do you think Macrodroid would differ? – kBisla Jul 13 '17 at 11:33

If you're rooted and using greenify then there's this option of aggressive doze. Once try it and if not greenify then use kernel Adiutor to tweak your processor as per your need.

  • Good recommendation, this would be more impressive if you give instructions on using kernel auditor to throttle CPUs – xavier_fakerat Jul 13 '17 at 15:16
  • Sure, after entering into kernel Adiutor swipe left and select CPU and now you can see the cores and their respective frequencies.Just scroll down and you'll find CPU governor, now change it to Powersave. I hope there'll be Atleast a small change in the battery life! – user8300165 Jul 13 '17 at 15:24
  • And one more thing in case of one plus 3 i guess there are custom kernels available in XDA maybe you should give them a try! – user8300165 Jul 13 '17 at 15:25
  • Since OP has Tasker, it is possible to intergrate kernel auditor into tasker as a plugin of some sort (I know Tasker alone has this functionality however) – xavier_fakerat Jul 13 '17 at 15:37
  • Never integrated tasker with Adiutor.Maybe you can try it yourself. – user8300165 Jul 13 '17 at 15:44
