I updated to lollipop on my Moto X phone and I am now seeing a large percentage of my battery being used by Cell Standby. How do I stop this?
I have dealt with this bug a lot. (Moto x gen 1) The good news is that Google has assigned someone to fix it, however right now the best way to fix this is to force close apps when you are done using them.
What is happening is when an app requests cellular data, your phone's data radio turns on. In most cases the radio immedietly turns off when it is done, but there is a lollipop bug that keeps the radio on until the app that requested it is force stopped.
The force stop can be done manually through the running apps list in settings, but there is another app called Greenify that will do this for you automatically. No, you won't need the paid version. Just let the app have accessibility access and it will force close apps for you on request.
If you want proof, here is what my cellular battery usage is when I forget to use Greenify all day.
And when I use it vigorously
(I am in no way affiliated with Greenify or its development team)
One possible solution:
Short answer: Settings (gear) -> System Update -> Update Motorola software
Medium answer: Using Moto X (2013 a.k.a. Moto X1 ) “System version” is now “222.21.19...." Also helps to use MOTO instead of GOOGLE assistant to save battery
Long answer: I finally let “Motorola Update Service” upgrade from Android 4.4 to 5.1 Also let “download manager” upgraded apps. BUT it reported “Cell standby” using over 20% of battery. This is after disabling or stopping every App possible and letting it sit on the desk.
But all the other upgrades have "nag screens" or are "automated". "Update Motorola software" is a manual process. After the update... the "screen" is back to being my top "Battery" user, everything else is 1%.
