Not consistently on this site — the longest stated runtime belongs to a trimmer that publishes no price at all, and the most expensive all-in-one we cover, at $125, states nothing about its battery.
The published figures do not track price cleanly.
The Braun BT9545 states 180 minutes, and publishes no price on amazon.com. The Braun BG3530 at $57 states 80. The Philips S7887 states 60 minutes on a one-hour charge, and publishes no price here either.
Meanwhile the Philips MG7962 — the most capable all-in-one in our catalog, at $125 — publishes nothing about its battery at all. The $57 body groomer states 80 minutes; the $125 kit states nothing. Runtime is not what the extra money buys.
What price does track more reliably in this category: the cutting element, the number of published specifications, and the attachment set.
Battery figures are worth reading per product rather than inferring from the tier.
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.
