It’s natural to assume that when a tech company updates its devices, everything gets an upgrade. But that isn’t exactly the case with Apple and its iPhones. When the iPhone 6 came out, it had a 1,810mAh battery pack. Following that, the iPhone 6s got only 1,715mAh. But a new rumour from OnLeaks’ source claims at least the upcoming Apple flagship won’t have it any worse than that and it’ll have 1,960mAh battery. However, we don’t know if this will improve battery life since we don’t know how the performance of the new device will be and if it’ll need more power to support its performance. For now, this is also just a rumour so we’d have to take it with a grain of salt.
