Measurements
This website does not contain all information on measurement and calculation methods related to smartphones and tablets.
Please find the complete set of requirements in the energy labelling regulation (EU) 2023/1669, Annex IV.
Measurement of the battery endurance in cycles
Batteries shall be tested for battery endurance in cycles until the battery has, in a fully charged state, a remaining capacity of at least 80 % of the rated capacity.
The battery shall be tested according to the default charging algorithms implemented by the manufacturer.
The resulting number of cycles shall be rounded down to full hundreds.
The battery endurance shall be calculated with the operating system version installed on the product model at the date of placement on the market.
Measurement of the ingress protection
Ingress protection against particle and moisture ingress are stated as an IP code, corresponding to the levels listed in Annex IV, table 5.
Tests shall be performed without protective cover.
The scale involves 8 levels including dust tight and protected against immersion in water up to 1 meter depth: IP67; (IEC 60529:1989/AMD2:2013/COR1:2019)
Table: Ingress protection rating levels
| Rating level | Ingress of solid foreign objects | Ingress of water with harmful effects |
|---|---|---|
Object size | Protection against | |
| 0 | No protection | No protection |
| 1 | ≥ 50 mm | Vertical water dripping |
| 2 | Protected from touch by fingers | Water spray less than 15 degrees from vertical |
| 3 | ≥ 2,5 mm | Water spray less than 60 degrees from vertical |
| 4 | ≥ 1 mm | Splashing of water |
| 5 | Dust-protected | Jetting of water |
| 6 | Dust-tight | Powerful jetting of water |
| 7 | n.a. | Temporary immersion, 1 m depth |
| 8 | n.a. | Continuous immersion, 1 m or more depth |
