I totally feel with the poster above. I told myself that the N76 is going to be my next move from the W850I that I currently use(mainly as a MP3 player) but after I've confirmed with the fact that the battery supports the N76 is mearly a 700 capacity, I felt I've fallen into my miserable black hole again as I've being looking for a phone with decent MP3 player capability(Equalizer is a must - Moto E6 is out of the water again) and yet backed up by great battery life, 1000mah and above.
I'm not a fanboy of any manufacture by all means as I've being using many phones in the past years, check my profile. However, I find the Walkman series of the SE to be quite pleasing in terms of its battery life and MP3 player user friendliness.
