Counterclockwise: smartphone battery endurance has doubled since 2010

28 January 2018
A steady rate of improvement means modern smartphones spend less time attached to the wall than their predecessors.

    I don't know how GSMArena get their battery endurance ratings of 70-90 hours when the average Screen-On-Time of smartphones today is only 4 to 6 hours. You can only actively use your smartphone for not more than 6 hours on average per full charge. So how do get 70 hourd endurance rating?

      1st answer: its the Endurance Rating based on GSMArena's testing profile. It's basically how many hours you can use it with 1 hour of 3G calls, 1 hour of video playback, 1 hour of web browsing daily, then set on standby. You can learn more here:

      However, this entire article is wrong/flawed because GSMArena's testing, especially before 2016, is flawed because of their differential screen brightness level, video media used during playback, differences in software, and the introduction of LTE into the market. Essentially a current phone (2018) might have a similar figure to a phone much older (2013), but the older phone was tested using a dimmer screen, lower quality/less taxing video, and slower Data Connection. Or quite the opposite, a new phone (2017) might have drastically higher Endurance Rating figure than an older phone (2014), and the older phone may have used the same Data Connection and Taxing Video Playback, but the older phone may have been tested at a much higher brightness rating (eg 310 nits) as opposed to the new device being tested at the standard 200 nits level. We will never know which scenarios come into play on certain handsets, the only solution would be to source Hundreds of phones, and refurbish them with Fresh Batteries, and run a properly controlled Scientific experiment on all of them.

        The sad part is that the efficiency doesn’t grow, in part due to technology upgrades being used to make chips faster instead, and due to displays being bigger and brighter.

          1th question, what do they mean with endurance, how long a phone can run in standby before being charged again??
