Special steps need to happen in order to ensure proper measurements are taken without upsetting the normal operation of the unit under test. Measuring sleep currents can often cause problems with units because of the equipment used to measure very low currents accurately requires a large resistor in series with the power supply.
The average current consumption while advertising is 962uA - 1.62mA I think this is OK. The average current consumption when sensor device enter into sleep mode is 562uA (Which is very high) We have disabled all used peripheral before enter device into sleep mode as like below:
For battery-powered applications that spend a large amount of their time in standby or sleep mode, IQ can impact the battery's run time by years. For example, using an ultra-low-IQ buck converter like the 60-nA TPS62840 to power an always-on application, such as the smart meters shown in Figure 1, enables 10 years of battery run time. Figure 1.
In this scenario, the sensor can operate in sleep mode and wake up only when necessary. While in sleep mode, the IC consumes a small amount of power from the battery — this current is the operating IQ. The smaller the IQ, the longer the battery life.
However, note that the maximum VOUT among these batteries is 3.7V, which may be insufficient for a number of applications. This is when a boost converter becomes vital. MPS provides a variety of synchronous step-up (boost) converters that can be used to step up a battery’s VOUT such that it can provide a sufficient VIN for the receiving system.
It may be difficult to understand why the IC consumes current even though it has shut down. This is because some of the internal circuitry, such as the start-up loop, still leak small amounts of power to the ground (GND); this leakage consumes battery current (see Figure 3). Consider the following real-world example.

BU-808a: How to Awaken a Sleeping Li-ion
Some use here really wrong words! like "high current" or "high voltage". This is most stupid and dangerous. To boost a battery you use a healthy battery of the same sort to "wake up" a dead cell. This process takes only seconds or perhaps 20 seconds or a few more. Very rapidly the voltage of the dead/sleeping cell will go up. (it is like ...
