| A smartphone with a week of battery life is likely to be possible now. Just do this: 1) use the latest most efficient panel technology - let's say the latest Super AMOLED from Samsung 2) Use a very lower resolution such as 480x320 (also the initial resolution of the iPhone, which many thought looked "great" a few years ago) 3) Put a screen that's as small as possible on it - let's say 3.5" (you now...the "ideal" size that the iPhone used to have?) 4) Put the lowest power chip you can find in it (even if that means lowest performance - although a single-core 1 Ghz Cortex A7 should do the trick). 5) Put a relatively powerful (enough to handle that resolution easily), but very efficient GPU in it 6) Use other components that are also cutting edge in terms of power efficiency. 7) Put a 3,000-3,500mAh battery in it, even if it makes the phone 10-12mm thick (so like the Nokia Lumia 900 that many liked at the time for its "design", despite its thickness). I would be surprised if all of this didn't lead to a week of battery life for the phone. The "problem" is this phone will be quite expensive unlocked (probably close to $300) due to its cutting edge/more efficient components, yet at the same time it will look like a $100 cheap phone in terms of "specs". So where I'm going with this is that the market doesn't want such a phone even if it has a "1 week battery life". The market wants "PC-like performance", 2k resolutions and 5.5" screens more than they want "1 week battery life". And the other problem is that they want those specs to keep going up, and as long as those go up, battery life can't go up much either. They optimize for performance and high specs rather than battery life. So if an OEM can choose between a 1080p panel with 30 percent less power consumption and a 2k panel with the same power consumption, they go for the 2k. And that's how our phones get stuck forever in the ~1 day battery life. |
