Batteries are a pain for everyone. It’s something that we have been complaining about after manufacturers fixed most of our other complaints with devices. Although two-year contracts are a thing of the past, there are still not that many users that update on a regular basis, which means that by the end of the device’s life, your battery life may just be a few hours.
Sony is looking to combat that by testing out ‘Soft Charging’ via its Marshmallow AOSP beta software for the Xperia Z2 and Xperia Z3. What this does is add a toggle to your settings that will essentially slow down the charging of your device so that your device doesn’t overheat your battery. This will remove any chance of potentially damaging your device due to charging it too much or using it will charging.
The best use case that we can envision for ‘Soft Charging’ is for when you plug your phone in at night when it’s time to go to bed. However, it’s a bit counter-intuitive to the various quick-charging options from Qualcomm, or the Dash Charge capabilities of the OnePlus 3. Regardless, saving battery life is the name of the game, and you don’t want to have to be plugged into a charger all the time throughout the day, so maybe Sony’s onto something here.
