Apple uses Lithium Ion batteries, arguably the best battery you can buy. Any battery you get from an authorized dealer will be the same Apple uses, and any that are not authorized are likely to be dangerous, or at least lower quality.
The battery that is most suitable as an iPhone cellphone battery replacement is a genuine iPhone battery from Apple. You should not take the risk of damaging your iPhone by purchasing another type of battery.
Personally I like the IPhone 3g. They are a little big but efficient. If you are looking for a long battery length, the IPhone doesn't last very long on batteries.
The Apple iPhone 6 Plus has a better battery life than the Apple iPhone 6.
The batteries are made in Taiwan by Simplo Technology (60%) and Dynapack International Technology.
Nokia N900 has got a better battery time plus it has a 5 MP camera which no iPhone has.
You get faster internet then the original iPhone.
iPad has a larger battery so it lasts longer on avetage

Depend on the settings in some case yes.
a battery
1432 mah battery
