Different generations of batteries, improving capacity and better for environment
Lead-acid batteries
Ni-Cad (Nickel-Cadmium)
NiMH (Nickel-Metal-Hydride)
Li-Ion (Lithium-Ion)
Li-Poly (Lithium-Polymer)
Samsung Galaxy S3 - Li-Ion 2100 mAh battery
iPhone 5S - Built-in rechargeable lithium-ion battery
iPad - Built-in 25-watt-hour rechargeable Li-Poly battery
Batteries have been improving

A lot still needs to be done!
Lots of advancements in the battery technology
Solar cell under the screen
Future generation Li-Ion battery, 2000x more powerful

The more the number of pixels, the more the need for computation
iPhone 5S (1136x640), Galaxy Note 3 (1080 x 1920 pixels)
True colour (24 bits) requires 3 times the computation that of 256 (8 bits) colours
Galaxy Note 3 (16M colours)
The bigger the screen size, the more power it needs
Galaxy Note 3 (5.7”), iPhone 5S (4”)
More processors, need more power
Dual core (2 processors), Quad core (4 processors)
More radios suck more power
Wi-Fi, 3G, 4G, Bluetooth, NFC, etc.
We need bigger and better batteries

Facility to charge devices in public places is a boon for end user and good advertisement for companies and airports, etc.
Wired charging stations are being replaced by wireless ones
Competing for power at public spots
![Page 18: Smart Batteries](https://reader033.vdocument.in/reader033/viewer/2022052323/5590cb731a28ab48538b477f/html5/thumbnails/18.jpg)
‘Smart charging’ can give higher priority to subscribers, devices of certain brands, devices with lowest charge remaining
Competing for power at public spots – Next Gen
