Charge Time and Battery Life

Charging 3100 shaver fullyCharging the Philips Norelco 3100 fully takes from six to eight hours.  This is pretty long charging time, but since the shaver can be used while plugged into the charging cord.  it is not a huge problem. A full charge should provide about forty-five total minutes of use.

When it is time to recharge, the unit plugs into the charging cord so the lithium ion battery can recharge. It does take around eight hours to recharge fully, but it provides around forty five solid minutes of shaving time when fully recharged. Which equals out to somewhere around one full week of shaves.
This is very comparable to many higher end shaver models, a fact that is important to consider when weighing electric shaver options.

The Charging Unit 

The charging unit (as part of the charging cable)  is on the smaller side, which does make it pretty travel- and storage-friendly. When the unit’s battery is low and needs to be charged, the LED readout will alternate blinking from orange to green. After being plugged in to charge, the LED readout will blink green continually, until the shaver is fully charged. The charging cable can be plugged directly into the shaver and then into the wall.

This is a very convenient feature for a dry-use only electric razor to have, and probably explains why there is no cleaning brush included with the Norelco 3100 Review.

However, some users have reported that it is not all that easy to clean, and the advertising makes it sound simpler than it really is.

You may need to take the shaver apart completely every couple of days in order to clean it properly, instead of using the easy-open option every time.  But that seems like pretty small fries, in light of all of the other low-cost and high quality properties of the Philips Norelco 3100.
