Call reception : it was good I would say but the mess and chaos was the way calling system works the phone.Names and contacts get all mixed up.
Performance : Processor is too old and bad. The way they showed in the advertisement the 430 snapdragon processor was too clever but actually it was good at that time not now.The 28nm chipset lets the phone heat up very fast.
Look and feel : The back panel doesn’t seem to be metallic as mention. The phone is heavy and feels bulky in hand.
Display : the screen was a dessert to the eyes and never hurts the eyes.Viewing angles are good and the color saturity is fine I would say.
Battey backup : The battery was massive definitely. There is no doubt in that. The 4000mAh battery is quite a big battery and keeps the flow for about 28-30hours on a moderate usage .But the con of the battery is that it charges very late , it takes almost 3hours.
User experience: the user experience is fine as it has stock Android with a very little tweaks of vibe UI of Lenovo.
Physical buttons : the buttons are fine and tacticle enough for a good usage. And are placed fine.
Cons : Nevertheless the cons were too higher than the pros so I devote the lenovo k6 power.
