Blog “Which? Tech Daily” ran the HTC 10, LG G5, Samsung Galaxy S7, and the Apple iPhone 7 through a series of battery tests.
The most notable difference:
Whilst the iPhone 7’s 712 minutes of call time (nearly 12 hours) may sound acceptable, the rival Samsung Galaxy S7 lasted twice as long – and it doesn’t even have the longest lasting battery. The HTC 10 lasted an incredible 1,859 minutes (that’s almost 31 hours).
So just why does the iPhone 7 have such a poor battery life? It may sound obvious, but the majority of the fault lies in its comparatively tiny cell. Smartphone batteries are measured in milliampere hours (mAh). The iPhone 7 has a 1,960mAh battery, whilst the HTC 10 has a 3,000mAh battery: it should hardly be surprising that one battery nearly half the size of another offers roughly half as much charge.
So was this a fair test? Is call time a fair measure of battery life? In browsing/email testing, the battery life was much closer, though the iPhone still finished last.
To me, the bottom line is a battle between thinness/weight and battery life. I rarely have to recharge my iPhone battery during the day. So, for me, the thinness of my iPhone is worth the shorter battery life.
UPDATE: The test compares the iPhone 7 (138.3mm x 67.1mm) against the HTC 10 (145.9mm x 71.9mm), the Samsung Galaxy S7 (142.4mm x 69.6mm), and the LG G5 (149.4mm x 73.9mm). All three competing phones are a fair bit larger than the iPhone 7. Bigger phone equals bigger battery. Thus the addition of the word “flawed” to the post’s title.
