A recent report has revealed that the iPhone 6 battery will be thinner than the iPhone 5S meaning the phone overall should also be slimmer.
The report has come from hit-and-miss source DigiTimes, but we've heard lots of rumours about Apple thinning down its iPhone 6 so we're inclined to believe this one.
The iPhone 6 battery is reportedly only 2mm thin making it a millimeter thinner than the current iPhone 5S whose battery comes in at 3mm.
Despite slimming down the battery it still has a similar capacity to the current version, claims the report. Previous reports suggest that by using the latest sapphire glass and in-cell touch display, the screen will be thinner also.
This attempt to thin down the device is also proving to be a challenge which is part of the reason that the rumoured iPhone Air, at 5.5-inches, won't be available until 2015.
Apple is expected to unveil the iPhone 6 and iPhone Air from September time when the iPhone 6, at least, should be available.
This report from DigiTimes is very similar to a report from the Commercial Times which was released last April. Both publications are Taiwan based in China, where a large proportion of Apple's manufacturing takes place.
