Hey, remember when Nokia 2 passed through the FCC? Buried under a mountain of wireless connectivity tests was the battery capacity a whopping 4,000mAh! Thats a huge jump over the 5, 6 and 8 models, all three of which have around 3,000mAh.
The Snapdragon 210 chipset doesnt use a lot of power not because its very efficient (its a 28nm chip), its just not very powerful. Couple that with the rumored 4.7-5 screen of modest 720p resolution, the battery life should be stellar. Certainly better than HMDs current entry level phone the Nokia 3 and its 2,630mAh battery.
Anyway, the FCC also lists the charger 5V at 2A, a typical phone charger in other words. We werent expecting fast charging (the 5 and the 3 dont have it either), but that chunky battery is going to take a while to fill up at this rate.
