How do the new iPhone 5s and iPhone 5c batteries stack up against the iPhone 5? Apple claims that its new mid-range smartphone includes an improved battery with 10 hours of talk time or web browsing, while its mid-range entry offers a slightly improved life-span compared to the now-obsolete iPhone 5. Unfortunately, Apple never gets into the specifics of battery size during its launch events, but AnandTech discovered an FCC filing that provides more detail. The gist? Apple was able to squeeze a bigger battery into the iPhone 5s, even though the body is the same size as the iPhone 5. Nice work, Jony Ive.
Both new phones feature bigger batteries than the one found in the iPhone 5, based on both watts and milliamps per hour. While the iPhone 5 battery offered 5.45 Whr and 1,440 mAh of juice, the iPhone 5S boasts 5.96 Whr and 1570 mAh, while the iPhone 5s battery offers 5.73 Whr and 1507 mAh. All three smartphone batteries run at the same 3.8 volts of direct current electricity.
Overall, the iPhone 5s battery offers about a 10 percent size increase over the iPhone 5, while the 5s battery increased by five percent in size. It’s most impressive considering that Apple didn’t change the size of the iPhone 5s, so it’s basically fitting more battery into the same space as before while adding a more efficient A7 processor. Hopefully that results in a nice bump in battery life.
