Apple may have been dealt a huge blow in its continuing fight for smartphone dominance.
Reports are emerging that the next iPhone - either the 'iPhone 6' or the renamed 'iPhone Air' - might be delayed until 2015.
The news reports say that the bigger battery required by a larger iPhone has not yet passed testing, and might not make the deadline for a September launch.
The bigger phone may not be the only iPhone scheduled for release this year, however - meaning Apple will still have something to show off by September.
And as ever, this is just rumours layered on top of rumours. So don't panic just yet.
