Re: My Moto G's battery is draining very quickly-please help
Is your phone using Android systems?
Normally Android system eats more battery than others.
Are you sure the battery is fully charging?
If after a full night's charging, you notice that your smartphone battery drains super-fast, then it's worth checking first thing in the morning whether it actually fully charges. If not, then you're looking at a defective charger.
More active applications drain the battery fast. (Google Play Services consumes a lot of battery. Unfortunately, you can't stop it because it's a crucial Android feature which lets your apps communicate with each other on your phone. Still, you can bring it under control).
Go to Settings > Applications > All > Google Play Services . Here, tap the Clear cache button. This should refresh Google Play Service and stop it draining your battery. Repeat this process once a month.
Get rid of unwanted (not most important) applications which will save battery power.
If you are using 3G or 4G service and if Your carrier doesn’t have 4G /3G coverage in your area or low/bad signal, then your phone uses more battery.
If none of the above reasons, then your battery may be dying..!!
