Sony Xperia Marshmallow update beta includes 'soft charging' allowing the battery to live longer
The Sony Xperia Z2, Sony Xperia Z3 and Sony Xperia Z3 Compact are getting updated with a beta version of the Marshmallow update with software version 23.5.A.1.238. This includes a feature called Charging optimization better known as "soft charging." With this feature enabled, the battery charges up to less than 100% when you plug in.

Studies have found that you can increase the number of years that a battery can hold its charge, by not letting it fully recover to 100% each time you plug in. Of course, the caveat is that you will never get to experience the full life of your battery on a day-by-day basis. You might have to charge your phone more often than usual over the course of a week, a month, or even longer.

The first time you charge your phone following the update, you will receive a message that 'Charging optimization' is enabled. You can disable this by going to Settings > About phone > Status > Charging optimization.

In addition to the Charging optimization feature, the update includes the latest version of the Xperia Home launcher, which now includes support for landscape orientation, bug fixes and a number of improvements. Xperia Z2, Xperia Z3 and Xperia Z3 Compact owners who are members of the beta program will receive the update shortly.

Interesting. I thought charging a battery halfway decreases the lifespan of the battery.

Batteries are sort of like balloons or car tyres, if you always pump air to the max point every time, and let go of the air, it is going to last way shorter than if you just pump it to around 80-90%, this is because the material holding the air which in our case rubber looses integrity if you for it to expand to the maximum each time, same goes for batteries as they are actually just storing electrons rather than air particles.

It was true, about 10 years ago. Today's batteries live longer when the charge is kept around 50% and are degrading faster if kept above 80%.

So soft charging is for those people that keep their phones more than 2 years. I can see how it would be useful to my mom and other older people I know that don't often change phones like I do.
