Lenovo Vibe P1m has a very good battery life it could last upto 1.5 days with normal usage. It has 3900 mAh battery and it has a dedicated button to activate power saving mode. The phone is dual sim 4G and it has 1 gHz peocessor with 2 GB ram and 16 GB internal storage. The display is a 5 inch 720p, which is good. The camera is 8 mp on back and 5 mp on front but the quality is average. The main problem is that the phone lags a lot and the processor is not good enough to run heavy games. The fast charging takes more than 2 hours to charge the phone fully. This phone is very good only in the battery department everything else is average.
