BatteryBox will allegedly work for more than 5 years on both devices.
Lithium ion batteries are generally degradable over time, thus even the best smartphone regardless of how well they function in the first few years will experience a decrease in their battery retention. Despite whatever claims its manufacturers make, this is a known fact and the tragedy of the smartphone. Having established this, the attention needs to be diverted towards solving the problem and that’s where BatteryBox comes in. BatteryBox prevents batteries from attaining degradation overtime and allows devices to be powered efficiently even after five years of usage with its power efficient BatteryOS!
Regarding battery power, it is not just the mAh count which makes a difference as shown by Intel’s Haswell processor which has transformed the notebook experience. This processor has allowed for 3 more hours of battery usage in the macbooks without having to dramatically change the battery size. Thus energy efficiency can be materialized within the confines of the chipset of this unique processor.
BatteryBox does not just create an increase in the number of battery hours; rather it can even carry enough charge to power 8 iPhones. It entails an impressive facility of 12,000 mAh and increase in the number of years of usage is not expected to decrease its full capacity. Even consequent to 3000 charging cycles, BatteryBox is able to retain 96% of its charge capacity. Coming to the price the BatteryBox just costs $139 which makes it a must buy considering its great usability.
