New results are in examining battery life for some leading smartphones across carriers and T-Mobile continues to demonstrate superiority compared to Verizon, Sprint and AT&T. Some of the results are quite impressive for T-Mobile and overall paint a widely divergent picture when it comes to battery life. For instance, the Samsung Galaxy S 5 was able to go 10 hours 57 minutes on the T-Mobile network while lasting only 7 hours 30 minutes on Verizon. Similarly, the HTC One (M8) was able to go 10 hours 50 minutes on T-Mobile, but only 8 hours 42 minutes on AT&T.
The testing was conducted using the Laptop Mag Battery Test app for Android. The app surfs 50 popular web sites, pausing for 60 seconds on each. This is repeated until the battery runs out. During the test, Bluetooth, NFC and Wi-Fi are all turned off and screens are set at a consistent brightness. The testers also make sure smartphones are experiencing at least three bars of service on a mobile carrier’s network.
Laptop Mag has been conducting these tests on a periodic basis for a while now and this latest test is consistent with previous results showing T-Mobile to be the leader amongst the four major carriers. Over 36 months, T-Mobile devices have lasted almost an hour longer on average than their closest competitor, Sprint. Verizon and AT&T bring up the rear, just a few minutes behind Sprint. Laptop Mag does point out that Sprint’s portfolio tends to be more weighted with non-LTE devices, so their results may be a little more favorable than they might otherwise be.
As far as the reason for the differences in battery life between carriers, there is no clear answer. It certainly seems like one of the items in play is the amount and types of bloatware loaded, or not loaded, by the carriers. T-Mobile has indicated that they work with manufacturers to “limit the number of preloads on devices and we work closely with developers of these applications to ensure they have optimal performance and minimal impact on battery life.” Another theory is that T-Mobile does a better job of moving data efficiently, possibly thanks to the bands that it uses, and there are less customers causing strain on the network.
There are lots of considerations consumers have to account for when selecting a carrier. Do you think average battery life is something you would consider when making a selection?
