Mobile consists of two parts, the software and hardware. Software is a set of programs that manage the activities of the mobile phone. File program for mobile phones called firmware.
The other part of a hardware device called a mobile phone. Hardware is the parts of the circuit which can be physically seen, touched and felt, such as resistors, capacitors, transistors and diodes.
Particularly in improving mobile devices, we must first be able to ascertain what part problem, software or hardware. It is very important to do because if we are wrong to analyze the damage will be even worse.
For it does not happen, then the following is a table guide in analyzing the damage to determine the corrective measures in software or hardware with the help of the power supply.
| Nu | Status | Power Consumption | Part | i.e |
| 1 | Off | 0.2 – 0.6 | IC Power | |
| 2 | When on network | 200 | - | |
| 3 | LED have been off | 100-130 | - | |
| 4 | When stand by | 10-15 | - | |
| 5 | When calling | 250-300 | - | |
| 6 | When off | 100 | IC UI | |
| 7 | When on | 100 | CPU | |
| 8 | When on | 0 | Hardware | |
| 9 | When on | 50 | Software | |
| 10 | When on | 10 | IC Power/26 Mhz Osc | |
| 11 | When on | <20 | IC Flash | |
| 12 | When on | >30 | IC Flash | |
| 13 | When on | >300 | IC PA | |
| 14 | When calling | >400 | IC PA |
