When compared to other flagship smartphones available on the market, then you will probably be disappointed.
Although they are behind other producers like iPhone 6S or Galaxy S6 in a couple of test, you shouldn’t be surprised.
It is very Obvious, that Lumia 950 XL does much better than the Lumia 950 since it carries a 3,340 mAh battery, whereas Lumia 950 has inside a slightly lower 3,000 mAh batter.
Still, considering the Lumia 950 sports a much smaller 5.2-inch display and the Lumia 950 XL boasts a larger 5.7-inch touchscreen (with similar Quad HD resolution), results shouldn’t be much different in some tests.
According to GSMArena, “the Lumia 950 XL posted way-above-average results when it comes to endurance on the 3G talk time: 17 hours. On the other hand, Lumia 950 was a bit disappointing, with almost half that time: 8:25 hours.”
In the web browsing test, MicrosoftLumia 950 lasted for about 7 hours and 29 minutes while the Lumia 950 XL lasted for 10 hours and 50 minutes. Which is only 6 minutes behind Galaxy S6’s result, that has a much lower 2,550 mAh battery.
The only problem is that the two smartphones are underperformed in their battery standby times, since they just lasted on a single charge for about 7 days.
In conclusion, on day-to-day use, with one hour of calling, 1 hour of browsing and 1 hour of video playback every day Lumia 950 should last you about two days .
On the endurance test, Lumia 950 XL posted a 62-hour battery life, which means that in real life you can use it for more than two days in similar conditions.
This result may look impressive at a first glance, but it’s no match for other phablets available on the market (Samsung Galaxy Note 5 scored 85 hours on endurance test).
