Well, that’s disappointing. Past leaks have indicated that the upcoming note 7 will have a huge 4000mAh battery that can power the device for 2 full days with moderate usage but as we inch closer to the release date, multiple sources tell that the Note 7 will indeed have a battery as small as 3500 mAh.
If you compare it with the previous generations, the Note 5 had a 3000mAh battery and the Note 7 is increasing it by 17%. That’s not bad but if you relate it with the recently released S7 Edge, it is smaller by 100mah (S7 Edge has a 3600 mAh battery) and the S7 Edge is a device with a smaller body having a 5.5-inch screen while the Note 7 has more room and a 5.7-inch screen.
So where did all the extra space go?
There are 2 factors for explaining that.
The first is the s-pen. The slot for the stylus takes up considerable amount of space on the device and the other is the iris scanner. This eye recognition setup takes up the most of the space under the top bezel above the display.
When you compare it with the Note 5, the battery space is actually smaller in the Note 7. But thanks to the newer technologies invented by Samsung that cramps more capacity into smaller space, Samsung was able to put in a larger battery in a smaller space on the Note 7. The software and hardware optimizations might ensure the maximum usage time as possible for the device.
That’s one hell of a technological feat.
