Yes, 9@9j really is the name of Philips’ upcoming mobile phone. It’ll be fun going into Carphone Warehouse asking for that… But the candybar handset does have one innovation – there’s a slot for a AAA battery in the bottom.
The technology comes from Israeli firm Techtium, and it’s called Backupower. The 9@9j is the first phone to have it inside. Battery firm Energizer is involved too – I grabbed Moti Puran – its Manager OEM Europe – to explain it.
