Smartphones these days are necessity. It is like blood in our body. We almost can't live without it. We still use it at least for calls and messaging.
These multibillion dollar multinational smartphone brands have become so good in terms of tech and marketing, they have reached saturation in terms of innovation and in terms of intent to innovate. These brands are so busy in counting money that they have stopped pushing boundaries.
I personally like companies which push boundaries in terms of tech to improve our lives. Obviously, we as a human race can't progress fast enough if all the responsibility is on the shoulders of kickstarter projects and small startups. Although, Big brands like Google, Apple, Samsung, Xiaomi, Huawei, etc. Have very deep pockets to innovate at a greater level and they do that by investing in other startups based on software services yet they lack all this greatness of investing when it comes to smartphone hardware which are practically the most used tech piece of daily human life.
Nowadays it is only about "how fast our CPU is?" Or "how better our camera is?" They thrive on the fact that their CPU and AI performance is improved by 10% than the last gen. But, there is one area they are practically not innovating at all. Guess what is it? . . . Guessed it yet? . . . . . It is battery. Battery is the most fundamental aspect of any portable electronic device. Without energy a $100 smartphone is equivalent to a $1000 smartphone because they both are equivalent if they remain switched off.
I get that battery R&D is costly that's why not every startup/small companies could do it. That's why these multi-billion dollar companies are crucial in this battery tech R&D. Somehow, this is the part where smartphone companies innovate the least. They depend on the mercy of processor efficiency to get more juice out of same size battery.
We want VR/AR, IoT devices, wearables, thinner smartphones but still want incredible battery life. VR is not picking up in the market because it can't provide quality experience without cable connection to powerful device. If you make it wireless and powerful then battery life is extremely, so we compromise despite having astonishingly powerful CPU and GPU in mobile form factor. Now, tech is at the point where we have almost perfectly nailed every other aspect of any portable device but battery life has started to hamper the pace of true innovation and awesome experiences as well.
We are still dependent on battery tech that was introduced many decades ago. We still don't have batteries that charges full in minutes if not in seconds. Companies have tech in laboratories that can charge your phone in less than 20 sec from 0 to 100%. This has been the situation for the past 7-9 years(http://bit.ly/2CbbNo8 & http://bit.ly/2RH15zx) but somehow I am yet to see anything close to it.
We are already reaching the limit in the CPU and GPU space(we're already at 7nm).
I think we will see the breakthrough in battery tech once innovation in CPU and GPU slows down and reaches full saturation. But until then I don't see anything going in the field of battery tech.
