How Long Do Android Phone Batteries Last?
Android phones come in all shapes and sizes, and so do their batteries. However, most share a similar lifecycle when it comes to battery degradation.
Typical Lifespan
Most lithium-ion batteries in Android phones last between 2 to 3 years, or roughly 500 to 800 charge cycles, before degrading significantly.

Why Patna's heat shortens battery life
Lithium-ion cells age faster in heat, and Patna summers regularly cross 45°C. A phone left on a bike dashboard, charged in a hot room, or fast-charged every day sees its 500–800 cycle rating used up sooner — so a Patna phone often needs a new battery closer to 18 months than the textbook 2–3 years. The tell-tale signs are a phone that drops from 100% to 20% in a few hours, shuts down at 30–40% charge, or grows warm during normal use. Once usable capacity falls below roughly 80%, the software still shows the same percentage but the phone empties far faster — that is the cell, not a setting.
Battery replacement cost in Patna
A fresh certified battery, fitted with labour, is one of the cheaper repairs and is done the same day in 30–45 minutes.
