3GS dies at 40% of battery left
Eventually after several cycles of turn off/die/turn on, the iPhone reports low charge/no charge and can no longer be turned on. When attached to power/charger, it reports very low charge and takes some time to charge to a state when it can be used again.
I have done all the usual things recommended in the FAQs such as backup/restore, update to latest version of iOS etc.
The iPhone is 21 months old so is obviously well out of warranty.
I am assuming that there is a battery problem as opposed to some application or process draining the battery. I have done the usual things with Exchange mail such as turn off 'Push' and restrict 'Fetch' to manual to preserve battery life.
The bizarre thing is the misreporting of the battery charge level. Does anyone know how to fix this? I can live with the shortened battery life until I can upgrade in a few months but not having the level of battery charge properly reported is a real pain!
Any help greatly appreciated.
