You will always want smartphones that have long-running batteries. While a host of various factors determine the usability and functionality of a smartphone, nothing can actually beat a phone that has a long-running battery life.

The Sony Xperia Z5 is the world’s first 4K smartphone that boasts of a very powerful battery life. In comparison to the Xperia Z5, the Galaxy S6 and Galaxy S6 Edge have less powerful batteries that undermine the performance of the smartphones. Let’s make an analysis of how the Galaxy S6 Edge, Galaxy S6 batteries fare against the Sony Xperia Z5 battery.

The Xperia Z5 has a cutting edge battery life that offers more number of live hours than you could imagine. You can put your charger into the drawer and stay tuned to your favourite TV shows or watch movies on the Xperia Z5 for two continuous days without the need of charging your phone, notes Sony Mobile. You may also use the Quick Charger so as to get up to 5.5 hours of battery power in just 10 minutes.

The Samsung Galaxy S6 and S6 Edge, on the other hand, have much shorter battery life when compared to the battery in Xperia Z5. After you have charged the batteries in the phones to full capacity, they hardly stay alive for an entire day. You have to keep with you an external battery pack to charge the phones to utilize more energy in battery, observes The Next Web. The battery power in the S6 Edge remains 40 percent to 50 percent even after low to medium phone usage.

In a Samsung Galaxy public forum website, many users of the Galaxy S6 complained about how the phone’s battery drained out very fast. Another user also complained how the phone would not switch on even after charging its battery for two hours.

Hence, an observation of the above discussion shows that the Xperia Z5 battery is more powerful than the Samsung Galaxy S6 and S6 Edge batteries.
