How Long Should Iphone 7 Battery Last. The LG flagship barely matched the iPhone 7 while having a battery size close to the iPhone 7 Plus. IPhone batteries use lithium-ion technology.
Apple will then replace it for 79 if you plan to keep the phone longer. However the big caveat here is those iPhones no longer last 12-20 hours on a single charge. IPhone batteries use lithium-ion technology.
Also it only drops from 100 to 99 in about an hour of standby.
The iPhone X out in 2017 contained a 2716 mAh battery that Apple claimed would allow the phone to last two hours longer than the 7. I know people with iPhones that are over five years old and their iPhones STILL have their original batteries. But how long will the iPhone 7 battery last. About 10 to 17 hours for all phones.
