While the iPhone’s battery life has been improved lately, for a full day’s use you still need a battery-boosting case of some kind.


I like this one from British hifi manufacturer Arcam. Its Music Boost (designed for the iPhone 6) does the necessary in terms of battery enhancement, boosting it by 120 per cent. The downside is that it increases the phone’s weight by 70 per cent and doubles its thickness – but it’s still a decent trade-off because Music Boost also serves as a Digital Analogue Converter (DAC) that gives your iPhone music a sizeable lift in quality and loudness.
