4G LTE vs. Battery Life

Although 4G mobile broadband networks average a data connection ten times faster than 3G, this added speed comes at a cost: faster battery depletion.  This increase in battery usage is mainly a result of spotty 4G coverage, that causes the phone search for a signal more often.

However, 4G networks use less bandwidth, so carriers are eager to get as many customers as possible to look past the battery issues, and start using this new technology.  The faster 4G networks also inherently cause people to use more data, since they are more likely to engage in bandwidth-heavy activities, which means cellular carriers can charge more for data plans.

The spotty 4G networks and relatively slow increase in battery technology means those that leave the 4G antenna active on their smartphones will have much lower battery life than if they used 3G only.  Because of it’s increased bandwidth efficiency and cost effectiveness, cell phone carriers are working diligently to improve their 4G networks, which will result in longer battery life.
