How Long CONDICE Actually Runs Between Charges
The spec says 70 minutes. Two weeks in, you're charging twice a week and nothing looks broken.
What CONDICE's runtime figures assume, how pattern and intensity change the draw, and the charging habits that hold capacity over two years.
The Short Answer
Expect about 70 minutes on the lowest pattern at the lowest intensity, and roughly 35 minutes at the highest combination. A full charge takes around 100 minutes over USB-C. If you use it three times a week for 10 minutes at mid intensity, one charge covers about two weeks. If runtime drops below 30 minutes on the low setting after two full charges, the cell has aged past the point where a habit change will help.
The Runtime Numbers, Unpacked
Published runtime is measured under a single condition: lowest speed, lowest intensity, room temperature, fresh cell. That is a fair number, and it is not the number most people experience, because most people don't stay on the lowest pattern for an hour.
CONDICE has 9 patterns and 5 intensity levels, which is 45 combinations. The draw varies across that grid, and the top end roughly halves the runtime. Think of 70 minutes as the ceiling and 35 as the realistic floor, then place your own use somewhere between them.
Why Pattern Choice Costs Minutes
Patterns with rapid direction changes work the motor harder than steady ones. A constant low hum draws less than a pattern that pulses every second, because each pulse is a small startup. Intensity adds on top of that, since higher amplitude means more current per stroke.
If runtime matters more than variety, pick a steady pattern at level 2 or 3 rather than a pulsing one at level 5. The difference in a 20-minute session is small. Over a week of daily use, it's the difference between charging once and charging twice.

Charge Cycles Over Two Years
Lithium cells are rated by cycles, not by months. A cycle is a full discharge and recharge, and partial top-ups add up to the same total. At three sessions a week with a 10-minute average, you're using roughly 30 minutes of runtime a week, which is well under one full cycle.
That works out to about 50 cycles a year, and most cells hold 80 percent of their original capacity past 300 cycles. In plain terms, the battery should still be useful in year three if the charging habits are sane. A 3x drop in six months is a habit problem or a faulty cell, not normal wear.
Heat, Storage, and Capacity
Heat is the variable people ignore. Charging on a bed, in a closed drawer, or next to a radiator keeps the cell warmer than it wants to be. Warmth accelerates the chemical side reactions that reduce capacity, and the effect compounds over hundreds of hours.
Charge on a hard surface in open air, and unplug within an hour of the indicator going steady. For storage longer than a month, leave it at about 60 percent in a cool drawer. Zero percent for months is worse than 100 percent for weeks, though neither is ideal.

Reading the Low-Battery Signal
Most devices signal low charge with a blink or a step-down in power. On CONDICE, the practical sign is a pattern that slows or an intensity that sags before the indicator warns you. Learn that sign, because it usually arrives 3 to 5 minutes before shutdown, and late at night is when you'll notice it most.
If the sag comes at 15 minutes instead of 60, the cell is telling you something. Charge it fully, run the low pattern, and time it. That single test replaces a lot of guessing, and it takes one evening.
A Charging Habit That Adds Months
Three rules. Charge before the device dies, not after. Keep the port dry and the cover closed. Don't leave it plugged in overnight on a soft surface.
None of these are dramatic, and none require a special charger. A standard 5V USB adapter is correct; a fast-charge brick doesn't shorten the charge meaningfully and adds heat. If the port cover feels loose, stop rinsing the device until it's replaced, because water in a USB-C port is a far more expensive problem than a dirty head. The honest trade-off is convenience: charging before empty means thinking about it a day earlier than you'd like.
When to Replace Rather Than Recharge
Replace when low-setting runtime falls under 30 minutes after two complete charges, when the charge indicator stops reaching steady, or when the body warms noticeably during a charge that used to stay cool. Those point to a cell at the end of its useful life, and no charging schedule reverses it.
Skip the replacement if you're simply using it at level 5 for 40 minutes and getting 35. That's the design working as intended. The limitation is the top end of the power range, not the battery.
