Non-removable Li-Po 3075 mAh battery

The Oppo F1s has a metal finish and great specs for the price. If you are a selfie lover, the F1s is something to go for. There aren’t a lot of smartphones on the market that provide a 16MP front camera that can take selfies as good as this smartphone. As an overall performer, the smartphone is pretty good in terms of battery life and daily tasks.
