As smartphones get smarter, so the battery lives become less & reliable, and we start to get into that panicked state at around 12 o’clock ever day where we only have 10% battery left. I know, I been there before, and it IS the most frustrating part of owning a smartphone. I have previously written about the fantastic Lenmar case for the iPhone 5, so was glad to see a similar case launched for the S4, which I know is a bug-bear for many S4 owners. The Lenmar Halo Galaxy S4 Power case sports an impressive 2600mAh battery kit, which pretty much doubles your battery life on your phone. The case is charged via a micro-usb cable using your computer and also has all the correctly placed cut-outs for chargers, headphones & camera flash. The case is fairly slim at only 15mm thick, ensuring the phone doesn’t become to bulky. And, at a RRP of R599, this case is a no-brainer in helping ensure those dreaded low-battery signals from the phone.
