Battery Life

The battery capacity of HTC U12+ is 3500 mAh, which is excellent both in general and in its own category. In our selection above, only the Huawei P20 Pro has a large battery with an impressive 4000 mAh capacity.

Battery life is one of the most essential features of a smartphone. A key metric is, of course, the battery capacity — especially within the same ecosystem (Android, iOS or other). Battery life can be affected by a bunch of factors, but the main ones are the main processor aka SoC, display and wireless radios (LTE broadband, WiFi, the cell towers location and more).

It is impossible to accurately estimate through benchmarks how much energy drain YOUR unique needs will generate. However, two things are surly always good:

  • A greater battery capacity
  • Very fast charging

The HTC U12+ has a very good battery charging speed of 50 mAh/mn, which is consistent with what Qualcomm’s Quick Charge 3.0 phones are capable off. The handset actually supports Quick Charge 4.0 but, like other OEMs, HTC did not include a 4.0 wall charger in the box, because 3.0 is deemed to provide the best value for the price. The fastest charging phones top ~75 mAh/mn.

It is generally not possible to predict real-world battery life by running synthetic benchmarks. Things such as display brightness, (LTE/WiFi) radio usage and distance to access points will vary too much. Also, how many apps installed and their activity is unpredictable. Battery capacity is the best battery-life indicator for YOUR usage.

The HTC U12+ does not have wireless charging integrated into the chassis. While this is the norm for recent high-end smartphones, many users will find it tolerable.

This product does not have a swappable battery, which is the norm for smartphones nowadays. Closed batteries cannot be taken out or easily exchanged, but they do allow for smaller designs and slightly bigger battery capacity inside the same product design.

Since the U12+ has a very large display, keep in mind that larger displays tend to utilize more power to accommodate the greater surface area to illuminate. It depends on the brightness levels displays are being setup at, but the potential for higher energy is there, so a greater battery capacity is preferable.

This device has an extremely sharp display (2880×1440). This is great to look at extremely crisp images, but handling 2.07M pixels more than a 1080p/FHD (2M pixels) screen will consume a bit more power from the battery. The good news is that you can reduce the rendering resolution to FHD/1080p so save some processor resources and therefore battery power.

Overall product rating: 8/10
