While the year 2014 is coming to an end, the smartphone department has seen a lot of advancements in terms of camera quality, processing speeds and screen resolution.
The tech world witnessed the launch of dual cameras, octa-core processor and curved flexible screen phone this year. However, to run these heavy multi-tasking toys, a powerful battery is required. That's why battery packs or portable battery chargers are becoming so popular.
However, sometimes one can't just depend on battery packs when it comes to buying premium smartphones. As after spending plethora, the buyer expects to have a smartphone, which at least can run for 10 hours on an average usage.
That is why we today at GizBot, we take a peak in our battery test database to see which phones offer much more endurance than others, and, as expected, the results might surprise you.
It's not always the most popular flagship phones, and not even the ones with the highest battery capacity that are at the top of their endurance game, but rather phones that are a good mix of sufficient battery capacity, well-managed processor throttling, and - most of all - power-sipping screens which contribute to the battery life of your smartphone.
