This article lists the schedules DJI publishes, explains which models let you change them, and sums up what the manuals say about storing and transporting the packs.
Self-discharge and auto-discharge are two different things
DJI's support article on the topic separates two effects:
- Self-discharge is the natural, slow loss of charge that every battery has because of chemical reactions inside the cells.
- Auto-discharge (DJI also calls it controlled self-discharge) is the battery's own electronics draining it to a preset level after a set number of idle days.
The reason, in DJI's words, is "to prevent swelling". A lithium battery kept fully charged for a long time ages faster, so the battery brings itself down to a safer level if you do not fly. DJI notes that it is normal for the battery to get moderately warm while this happens.
How long until it starts, by model
These are the rules from DJI's support article "Introduction to DJI Intelligent Flight Battery Auto-Discharging Rules". "Idle" means the battery is fully charged and not being used.
| Drone | First step | Next steps |
|---|---|---|
| Mini 4 Pro, Mini 5 Pro, Air 3, Mavic 3 / 3 Classic / 3 Pro, Avata 2 | about 96% after 3 days | 60% after 9 days |
| Air 3S, Neo, Neo 2, Avata 360 | 96% after 3 days | 80% after 15 days, 60% after 45 days |
| Mavic 4 Pro, Flip | about 96% after 3 days | 60% after 45 days |
| Mini 3, Mini 3 Pro, Air 2S, Lito 1, Lito X1 | about 96% after 1 day | 60% after 9 days |
| Mavic Air 2, Avata (first generation) | about 96% after 1 day | 60% after 5 days |
| Mini 2, Mini SE, Mini 2 SE, Mini 4K | about 96% after 1 day | 72% after 9 days |
| DJI FPV | about 97% after 1 day | about 60% after 5 days |
| Mavic Air, Spark | starts after more than 10 idle days | down to about 65% |
| Mavic Mini | no auto-discharge | discharge it yourself, see below |
For the Mini 2 family, DJI adds that the first step down to 96% takes about four hours. For the Neo and Neo 2, auto-discharge starts earlier if the storage temperature is above 45°C.
The original Mavic Mini has no auto-discharge at all. DJI tells owners to bring the battery down to 39-75% (when LED2 or LED3 blinks) if it will sit idle for over 10 days, either by using the charging hub as a power bank or by powering the drone on.
Can you change the timing?
On the drones in the table above, no. DJI lists every one of them as not supporting a manual start time.
Older and professional models do have a setting:
- Phantom 3: DJI GO > Settings > Aircraft Battery > Advanced Settings > Time to Discharge. The default is 10 days and it can be set to 1-10 days. The battery then drops to 65%.
- Phantom 4 series, Inspire 2: the same path in DJI GO 4. The default trigger is 10 idle days.
- Inspire 1: the same path in DJI GO.
- Mavic 2 Pro / Zoom: DJI GO 4 > Settings > Aircraft Battery > Time to Discharge. The default is 2 days for a battery at 70% or more, and DJI says it takes about three to four days to get from 100% to about 60%.
- Inspire 3: DJI Pilot 2 > Health Management System > Battery Management > Self-Discharge Setting.
On the Spark, charging the battery or powering it on cancels the discharge or resets the countdown. A single press of the power button to check the level does not.
Planning around it
The practical rule follows straight from the table: charge close to the day you fly. With a Mini 4 Pro or Air 3 you have about three days before the packs drop to 96%. With a Mini 3 Pro, Air 2S or Mini 2 you have about a day.
Losing 4% will not ruin a flight, but if you want every battery full, top them up the evening before. Keep in mind the Mini 4 Pro manual's warning not to charge a battery straight after a flight while it is still hot. The battery charges only between 5 and 40°C, and the manual gives 22-28°C as the ideal charging temperature.
If plans change and the batteries sit for a week, let them discharge. That is exactly what the feature is for, and charging them back to 100% every few days only keeps them full for longer.
Storing batteries for weeks or months
What the Mini 4 Pro and Air 3S manuals say about longer storage:
- Fully charge the battery at least once every three months to keep it healthy.
- Air 3S warranty: if a battery has not been charged or discharged for three months or more, DJI no longer covers it under warranty.
- Temperature: for storage longer than three months, the Mini 4 Pro manual recommends 22-28°C. Never store the battery outside -10 to 45°C. Keep it in a cool, dry place out of direct sunlight.
- Hibernation: if a Mini 4 Pro battery falls below 10% while idle, it goes into hibernation to protect itself from over-discharge. Charging wakes it up. New batteries ship in hibernation and are activated by their first charge.
- Sleep mode: both manuals say the battery enters sleep mode after long storage, and that charging brings it back.
A simple routine that fits those rules: let the packs auto-discharge after your last flight, store them in a cool room, and put a reminder in your calendar to charge them fully every three months.
Transport
For travel, both manuals recommend discharging the batteries to 30% or lower before transport. Airline limits on watt-hours and carry-on rules are a separate subject, covered in the article on taking drone batteries on a plane.
Checking battery health
In DJI Fly, Safety > Battery shows the cell status, serial number and the number of times the battery has been charged. The Mini 4 Pro manual rates its battery for 200 cycles and does not recommend using it beyond that.
The battery also checks the voltage difference between its cells. When it decides maintenance is needed, the drone will not take off and DJI Fly shows a maintenance prompt. The fix from the manual: fully charge the battery and let it rest for 48 hours. If it still does not work after two rounds of this, contact DJI Support.
