Mobile phones run on variety of different batteries depending on the phone, it’s shape, size and features. There are four types of battery available:

  1. Lithium Ion– They are rechargeable battery. It is much lighter than the earlier battery types. They have long life cycle. They don’t suffer from memory effect.
  2. Lithium Polymer–  These are an evolved version of Lithium- Ion battery. They are rechargeable. They perform similar function as Lithium- Ion Battery. They are much thinner than Lithium- Ion battery.
  3. Nickel cadmium– It is a early version of inexpensive rechargeable battery. It is not completely discharged before charging. It can suffer from “memory effect” which reduces the battery’s life.
  4. Nickel Metal Hydride– It is an evolved version of Nickel Cadmium Battery. But it also suffer from ” memory effect”. This battery can hold more power than the NiCb battery, and suffer from less “memory effect” than the NiCb.

The larger the number of mAH rating on the battery, the less frequent would be the need to recharge the phone. Following are the latest mAH rating of the battery:-

  • 2100 mAH (440 hrs 2G Stand By time)- Xiaomi Redmi Note 2, HTC desire 500 etc.
  • 3100 mAH (980 hrs 2G Stand By time)-Redmi Note 4, Samsung J5, etc.
