Short answer: the X100VI takes the NP-W126S and shares cells with the X100V and X100F — it does not use the NP-W235 from the X-T5. Fujifilm rates about 450 shots in economy mode (about 360 with the EVF, 450 with the OVF) and about 310 with the EVF in normal mode; 6.2K video runs about 45 minutes. No desktop charger is bundled, so you charge in-camera over USB-C or buy the BC-W126S, which takes about 150 minutes at +20°C. For a full day of street shooting, carry two cells: the hybrid viewfinder and IBIS both draw extra power.
Reading the official runtime figures
Fujifilm quotes CIPA values, and the same camera produces two different numbers depending on finder and power mode — 310 and 450 are not a contradiction.
| Mode | EVF | OVF |
|---|---|---|
| Economy | About 360 shots | About 450 shots |
| Normal | About 310 shots | About 450 shots |
For video, Fujifilm lists about 45 minutes of 6.2K, about 45 minutes of 4K and about 50–55 minutes of Full HD. Stabilisation, playback, Bluetooth and cold weather all shorten that; budgeting around 70% of the rating is safer in winter.
How many cells for a day
| Shooting intensity | Suggested cells | Why |
|---|---|---|
| Half-day street, mostly OVF | 1 cell + power bank | About 450 shots in economy mode is rarely exhausted |
| Full-day travel, mixed finders, some video | 2 cells | Double the roughly 310-shot normal-mode figure |
| Weddings, travel documentary, frequent 6.2K | 3 cells + charger | About 45 minutes of video per cell, rotate and refill |
Our NP-W126S replacement cell is rated 1210mAh, in the same class as the original 1260mAh. If you would rather skip the charger, the TNP-W126S USB-C direct-charge cell has the port built into the battery and is rated 1050mAh.
Charging and its real limits
The X100VI ships with a battery and a USB cable but no desktop charger. In-camera USB-C charging is the lightest option, yet Fujifilm’s support documentation states that charging stops when the camera is switched on while the battery is being charged in the body over USB or AC. In other words, you cannot shoot and charge at the same time; switch the camera off to refill.
The BC-W126S charges the cell outside the camera: AC 100–240V, 50/60Hz, supports both NP-W126 and NP-W126S, about 150 minutes at +20°C. Charging slows in the cold; the official charging range is +5–40°C. Fujifilm also advises using a compatible charger, since a mismatch can cause leakage, overheating or rupture.
Do not confuse it with the X-T5
The X100VI and X-T5 share a 40.2MP sensor and X-Processor 5 but not a battery: NP-W126S versus NP-W235 at roughly double the capacity. Spare cells from an X100V work in the X100VI and vice versa; no NP-W235 cell from an X-T4 or later will fit. The full list is in the NP-W126S category.
FAQ
Can I reuse X100V spare batteries in the X100VI?
Yes. X100F, X100V and X100VI all use the NP-W126S with the same shape, contacts and voltage, so they swap directly.
Can I charge from a power bank while shooting?
Not while shooting. Fujifilm states that in-body USB charging stops when the camera is turned on. Switch it off to top up, or use a battery with its own USB-C port.
Is a third cell worth buying?
Only for long video work or all-day trips without a socket. For stills, two cells rotated with an overnight refill is normally enough.
Why do I get about 300 shots when Fujifilm says 450?
450 is the CIPA figure for OVF plus economy mode. Using the EVF, IBIS, frequent playback and Bluetooth all lower the real count; that gap is normal.
