Battery Runtime
Like in most ultrabooks, the T430u's battery is not removable. Unlike the T430 and T430s, it cannot be expanded due to the lack of an UltraBay slot. The lithium-polymer battery features a capacity of 47 Wh, which is to achieve a maximum runtime of 6.6 hours according to Lenovo.
We recorded 6 hours and 16 minutes via the Battery Eater's Reader's test (energy-saving mode, wireless modules and GPU off, minimum brightness) in our assessments and can thus confirm the manufacturer's specifications.
The user can count on approximately 3 to 4 hours in practical use. Exactly 3 hours and 25 minutes in our standardized Wi-Fi test (energy-saving mode, GPU disabled, 150 cd/m²) is not a bad time. However, it is at best average for this device category (LifeBook U772: 5 hours 17 minutes).
The Battery Eater's Classic test (high-performance, wireless module and GPU enabled, maximum brightness) reduced the battery runtime to almost two hours. The full performance is demanded from the processor and graphics card here and they are not artificially throttled. The user can thus rely on the full speed away from the mains.
