The Braun BT9545 beard trimmer, at up to 180 minutes — the longest figure published in minutes here, ahead of the Braun AIO7565 and BT5525 at 120.
The published figures, longest first: 180 minutes on the BT9545; 120 on the AIO7565 all-in-one and the BT5525 trimmer; 100 on the Braun BG5555 and the Philips BG5480 body groomers; 90 on the Philips HC5630, HC7650 and MG3946; 80 on the Braun BG3530; 60 on the Philips S7887, the Remington MB5000, the Dollar Shave Club trimmer and the MANSCAPED Pro; 54 on the Panasonic ES-RT37; 50 on the Braun AIO3545, the Remington HC5811 and the Philips S5465; 45 on the Braun 3040s and the MANSCAPED; and 40 on the Grundig HS6230, which is the shortest here.
Two products answer the question in a different unit altogether, and they cannot be slotted into that list. The Xoomrscp nose trimmer states two to three months per charge at two minutes a use, and the Zorami more than six months at five minutes — the second on a disposable AA rather than a charge. Worked through, the Xoomrscp’s figure is a total of the same order as the BT9545’s 180 minutes. It is not the same measurement, and this page is not going to pretend it is.
Several products publish none at all, including both entry Philips rotaries, the Philips MG7962 and the Philips BG7025.
Longest is not automatically best. At three minutes a use, 45 minutes is two weeks — and the figure that saves a morning is the quick charge, which five products publish and the longest-running trimmer here does not.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
