And your point is?
As for the XA2 ultra it's the same hardware as the XA2 regular, but bigger in every way than the Nokia 7 plus.
Let me also tell you that The XA2 ultra also beats not just the nokia 7 plus, but nearly all similar phones too, like the Google pixel 2 XL (3500 mAh battery, 6 inch screen), the huawei p20 pro (4000 mAh, 6.1 inch screen), with like + 10 hours of endurance, which seems a bit funky if you ask me.
Anyway, some phones beat others, and vica versa. Don't be surprised too see differences.
As to why your N7 consumes more battery. There could be a lot of reasons:
- some app doing stuff in the background (has happened to me)
- if you are traveling, let's say on a train, and mobile data is turned on, it will keep switching between stations as you travel - This is really draining my battery in a lot of cases, and there's nothing you can do about it.
- It's android so everything goes
Maybe there's some optimization that can be done, but I won't expect anything ground braking. Maye in Android P
