The Moto G4 Plus includes a 3,000 mAh (11.55 Wh at 3.85V) non-removable lithium-ion battery. This is a 23% larger battery than the 2015 Moto G, which is in line with the 21% larger display. Where the display is the main source of power consumption, the Moto G4 Plus should perform similarly to the 2015 Moto G, but in other situations it could pull ahead.
In general the battery performance of the Moto G4 Plus is impressive, particularly considering the use of just a 3,000 mAh battery. Users should expect to see all-day battery life in all but the heaviest use cases, with this handset posting better battery life than its predecessor.
Motorola has also included capable fast charging for the first time in their Moto G line, which can charge the phone fully in under two hours and has very good burst performance.
