iPhone 8 and 8 Plus have smaller batteries than last year's iPhones
When Apple announces a phone, it talks more user experience and less numbers. That doesn’t work for TENAA, however, the wireless authority that certifies gadgets for use in China. So, here are the battery capacities of the iPhone 8 and iPhone 8 Plus.
The milliamp hour numbers have gone down 8% for both sizes of iPhone. And the phones themselves have not gotten thinner or lighter, quite the opposite in fact – they are 0.2mm thicker and weigh 10g and 20g more for the big and small ones, respectively.
|iPhone 7||1,960 mAh||2 GB|
|iPhone 8||1,821 mAh||2 GB|
|iPhone 7 Plus||2,900 mAh||3 GB|
|iPhone 8 Plus||2,675 mAh||3 GB|
Not that dimensions affect battery life. But the chipset certainly does. Again, Apple doesn’t say, but the Apple A11 Bionic chipset (used in all three new iPhones) is built on a 10nm process while the A10 was a 16nm chip. That certainly saves some battery. Also the in-house GPU should be more power efficient than the previous one.
And don't forget that the new iPhones support fast charging - 50% in 30 minutes. Wireless charging too (though the speed of that is unknown).
Anyway, the table also includes RAM capacities listed by TENAA – nothing has changed there. Even the iPhone X is suspected to have 3GB of RAM, though that one has not been certified yet.
What iPhone is that? iPhones have good battery life, especially the Plus series. I end the day with 10-15% on my 7 Plus and I'm a heavy user.

Why they do this is puzzling, to say the least. I remember swapping out my old 6s Plus' 2750mAh battery with a 2915mAh iPhone 6 Plus battery and it fit and worked just fine. I have no idea why they change the battery capacity every time. Since the 6 ...
