This lenovo vibe p1 has got 5000mah battery . even more than that of vibe p1m but its battery backup is less than that of vibe p1m. it has got all the necessary features such as the fingerprint sensor, nfc etc etc. the fingerprint sensor is not that responsive. It works for about 70% of the time. the lenovo interface is also fluid. it is a bit heavy device as it’s back is made up of metal. the battery is not user replaceable. and you can open only the upper portion of the back panel.still you get a lot of features in one device.
