My Nexus 5 is very inaccurate with its battery life, it will usually die at about 90-85% but occasionally it goes to ~40% before dying. is there anyway for me to tell it "Hey! You have 0% battery, fix it!" and "Your battery isn't full yet, charge some more" without root?
Buying new battery worked, N5 batterys can get "Mushy" or "Swollen" so replacement is key.
Buying new batteries is easy off of amazon and theres a billion youtube tutorials.
