    You cannot switch on the handset if the battery voltage is not present. From the battery voltage all other supply voltages of the C25 are derived, controlled by the power supply ASIC. The RF power amplifier needs an operation voltage of 5,4Volts, which is generated by a DC-DC step-up converter.

    The repairs for C25 and C2588 are identical unless otherwise noted. Lately a new version of the C25 has been introduced. This version has the main processor HiGold version 4.3 of the S25(88). Internally this C25 is therefore called C25V4. The level 2.5 parts are identical to the old C25 version.
