The most voracious component of any smartphone is not the CPU and not even the screen, and the radio transceiver. If a traditional phone device it is active only during a call, the rest of the time “asleep”, the “omnopon” for comfortable use constantly enabled mobile Internet. Experts Of Hi-Tech.Mail conducted an experiment examining the dependence of the battery life of smartphones from the operator and the type of wireless connection.
The methodology is the following: were taken the same model Sony Xperia on the same Snapdragon 801 chipset with the same set of installed applications and settings for data synchronization and used them with SIM cards from different operators: every day as your primary chosen another smartphone.
In the experiment, within a few days the device just carried in your bag without taking, to enable them to sync in the background and completely eliminate the factor of unequal conditions. In all cases you disabled the power saving modes, and was included Autoselect mode network. The experiment was conducted in Moscow and in St. Petersburg in various modes of activity.
In both cities the longest smartphones with support for LTE Cat.4 Snapdragon 801 worked in network “MegaFon”, the full cycle of battery discharge averaged on set of measurements 14 hours 05 minutes in Moscow 14 hours and 32 minutes in St. Petersburg. After switching to MTS result was 12 hours 36 minutes in Moscow and 12 hours and 12 minutes in St. Petersburg. If insert SIM card “Beeline” in Moscow smartphone runs out of power for 11 hours, 29 minutes and Saint Petersburg is 13 hours and 15 minutes.
Completely different situation is observed if we use the smartphone with support for LTE Cat.6. Here MegaFon loses the lead and the battery lasts for 8 hours 54 minutes in Moscow and 8 hours 13 minutes in St. Petersburg, while in MTS is 10 hours 03 minutes in Moscow 9 hours and 48 minutes in St. Petersburg, and in the “Beeline” — 9 hours 33 minutes in Moscow and 10 hours 39 minutes in St. Petersburg. Why is this happening?
“Smartphone running on high-speed networks, consumes more traffic even with the same pattern of use — for example, even when viewing a short video on Youtube at a higher speed will be set higher quality, and data will be downloaded more, says marketing Director of Qualcomm’s Peter Carson. – If we act strictly scientific, laboratory methods, and measure the power consumption of modems in megabits consumed on mA, two smartphones that have the same capacity and the wear level of the battery, one of which will support LTE Cat.4, and the second LTE Cat.6, when downloading the same amount of data over high-speed smartphone will be more energy efficient and discharged later.”
