Galaxy Note 9 iFixit teardown reveals a powerhouse battery
Samsung gets its battery mojo back.
The Galaxy Note series' big battery is back and better than ever in the Galaxy Note 9, as iFixit's teardown of the new phone shows.
Yeah, the 4,000-mAh spec tells you that it's probably pretty large -- typical phone batteries run between 2,500 and 3,500 mAh in comparison -- but according to iFixit, its 15.4Wh capacity blows past the preflammatory Note 7's 13.5Wh and the Note 8's crisis-of-confidence-shrinkage 12.7Wh.
Physically, it's 3.5 by 1.6 by 0.2 inches (88 by 42 by 6 mm), which is longer than the 3-inch width of an iPhone 8 Plus and less than 2 mm shy of the thickness of the iPhone X. (iFixit also says the Note 9 weighs 547 grams, or 19.3 ounces -- more than the entire phone weighs, so that's probably not correct.)
It carries on the low repairability tradition of the Note series, however, with glued-down battery and display. Its heat pipe does have more surface area for better cooling. iFixit also speculates that the new Bluetooth S Pen charges inductively when you dock it into the phone.
