EcoFlow Firmware Update Resets App Settings: Full Fix Guide

You accepted the firmware update notification in the EcoFlow app. The progress bar completed, the unit rebooted, and everything looked normal — until you noticed the fan running at full speed during a gentle overnight top-up, or found your solar session stopping at 100% when you had specifically set an 80% charge limit to protect the cells. The firmware updated successfully. Your settings did not survive.

This is one of the most common post-update complaints among EcoFlow owners, and it affects every model with configurable app settings: the DELTA 2, DELTA 2 Max, DELTA Pro, DELTA 3, RIVER 2, RIVER 2 Pro, and RIVER 2 Max. As one owner documented on batteryskills.com in June 2026: “the reset happens because the new firmware often installs a fresh configuration file. This ensures compatibility but temporarily wipes your personal preferences until you set them again.” (batteryskills.com) The guide below walks through every setting that typically reverts and the exact app path to restore each one.

Why firmware updates wipe your EcoFlow settings

EcoFlow ships its firmware updates as a complete image that includes a new default configuration file. When the update applies, the firmware writer replaces the existing configuration with the bundled defaults rather than attempting to migrate your preferences to the new format. This is the safe approach from a firmware stability standpoint — an incompatible setting carried over from an old firmware version could cause unexpected behaviour or crash a critical system — but it means the update treats your unit as if it has just come out of the box.

The settings that revert are not all equally visible. AC charging speed is immediately obvious because the fan noise changes. A charge limit reversion from 80% to 100% might go unnoticed for days until you check the app and see the unit fully charged when you expected it to stop. Scheduled tasks and automation routines are completely silent failures — they simply stop running without any notification in the app. This is why a systematic review of every settings screen immediately after an update is the correct approach, rather than waiting to notice something feels wrong.

The complete list of settings that revert to factory defaults

The following settings revert on every EcoFlow firmware update across all affected models. Not every model has every setting — the RIVER 2 has fewer options than the DELTA Pro — but these are the ones to check immediately after any update. AC Charging Speed: resets to the unit’s maximum rated input wattage (1800W on the DELTA 2, 3000W on the DELTA Pro). If you had it set lower to reduce fan noise, extend AC socket life, or comply with a caravan hookup current limit, you need to reset it manually. Charge Limit (upper SoC threshold): resets to 100%. If you had set it to 80% for daily use to reduce cell stress and extend cycle life, the unit will now charge fully with every session until you reconfigure it. Discharge Limit (lower SoC floor): resets to 0% on models that support a configurable discharge floor, including the DELTA Pro. If you had set a floor to protect cells during long-term storage or to reserve capacity for overnight appliance backup, this needs to be restored.

X-Boost toggle: resets to its default state, which varies by model. On the RIVER 2 Pro and RIVER 2 Max, X-Boost is enabled by default. If you had disabled it — for example, because you were running a device with sensitive electronics that did not tolerate the voltage reduction X-Boost applies — it will be re-enabled after the update. Smart Generator start and stop thresholds: resets to default percentages on the DELTA Pro and DELTA 2 Max. If you had calibrated custom start and stop levels for your specific generator runtime preferences (covered in our Smart Generator setup guide), these need to be re-entered. Scheduled tasks and automation timers: fully erased. All scheduled charging windows, off-peak charge schedules, and timed on/off tasks for AC and DC ports are removed and do not reload after the update.

Restoring AC charging speed and charge limits in the app

Open the EcoFlow app and connect to your unit via Bluetooth if you are nearby, or via Wi-Fi for remote access. Tap your device card to open its dashboard. Tap the Settings icon (gear wheel, top right on iOS, three-dot menu on Android leading to Settings). The AC Charging Speed slider is the first or second item in most model layouts. On the DELTA 2, it appears as a watt slider from 200W to 1800W. On the DELTA Pro, the range is 200W–3000W. Drag it to your preferred wattage and wait for the unit to acknowledge the change — the fan speed will adjust within a few seconds if you are charging.

The charge limit is usually labelled Charge Level or Charge to Limit in the same Settings menu, depending on your app version. It appears as a percentage slider. Set it to 80% for typical daily-use configurations where you want to slow cell degradation over hundreds of cycles, or leave it at 100% if you need maximum capacity for known extended-outage use. The discharge floor — available on the DELTA Pro and labelled Discharge Level or Discharge Limit — should be set back to your preferred minimum. A common setting for whole-home backup users is 20%, reserving capacity for emergency use while still delivering full overnight runtime to loads. For the DELTA 3 specifically, the charge limit and X-Boost settings are documented in EcoFlow’s official DELTA 3 troubleshooting guide.

Rebuilding scheduled tasks and Smart Generator thresholds

Scheduled tasks in the EcoFlow app are found under the Schedule or Task section, accessible from the device dashboard rather than the Settings menu on most models. Each task defines a time window, a day-of-week pattern, and an action (charge AC on, AC output off, DC output on/off). After a firmware update these are completely cleared. If you kept a record of your schedules — ideally screenshots — you can re-enter them in about five minutes. If you did not, you will need to rebuild them from memory. The most common scheduled task for DELTA owners is an off-peak charge window: AC charging turns on at 00:00 and off at 06:00, timed to a cheaper overnight electricity tariff. For owners who use the PowerInsight 2 monitoring dashboard, note that scheduled charge windows do not appear in PowerInsight — the task list in the EcoFlow app is the only place they are visible.

If your DELTA Pro or DELTA 2 Max uses a Smart Generator with auto start/stop, the start and stop battery percentage thresholds need to be re-entered under Settings > Smart Generator. The factory defaults are typically 20% for start and 80% for stop. If you had customised these — for example, starting the generator at 30% because your generator takes several minutes to warm up and you wanted a larger buffer before loads were interrupted — restore them now. The unit will use the default 20/80 thresholds silently until you reconfigure.

Backing up your settings before the next update

EcoFlow does not provide a settings export function, so the only backup method available is manual screenshots. Before accepting any future firmware update, open each settings screen in the app and screenshot it: the AC Charging Speed page, the Charge Limit page, the Discharge Limit page (if your model has it), the X-Boost toggle, and the full Schedule/Task list. On iOS, screenshots are saved automatically to your camera roll. On Android, they go to your gallery. This takes under two minutes and gives you an exact reference for restoring every value after the update.

You can also delay firmware updates rather than accepting them immediately. In the EcoFlow app, go to your device settings and disable Auto Upgrade if the option is present. This causes future updates to appear as a prompt rather than installing automatically, giving you time to screenshot your configuration first. For owners who have invested significant time in Smart Generator thresholds, off-peak charge schedules, or charge limit settings, this one-time change to auto-update behaviour is worth making now. EcoFlow occasionally pushes mandatory safety updates that bypass this setting — these are extremely rare and are reserved for units with known hardware risks, such as the DELTA Max 2000 recall firmware covered in our serial check and firmware fix guide — but for routine feature and stability updates, deferring lets you update on your schedule.

If settings are not saving after a firmware update

A smaller number of owners encounter a different problem after a firmware update: settings appear to save in the app but revert the next time the unit reconnects, or the slider does not register the change at all. This is distinct from the standard settings-reset pattern and usually indicates a communication issue between the app and the unit’s new firmware. The fix sequence is: force-close the EcoFlow app entirely (double-tap home or swipe up and close on iOS; recent apps on Android). Reconnect to the unit via Bluetooth rather than Wi-Fi — Bluetooth has a lower latency path to the device and does not route through EcoFlow’s cloud servers. Attempt to change the setting again. If Bluetooth changes now save correctly, the issue is a cloud-sync timing problem that typically resolves within 24 hours as the unit’s new firmware establishes its cloud session.

If settings still do not save over Bluetooth, the most reliable fix is a unit restart: power the DELTA or RIVER off completely using the main power button (hold 2 seconds), wait 30 seconds, and power back on. Reconnect in the app and retry. This clears any in-memory state left over from the firmware flashing process that can cause settings writes to fail. After a successful restart, settings changes should apply immediately and persist across reconnections. If the problem continues after a restart, check the EcoFlow support page for your specific firmware version — on occasion, EcoFlow has released a second rapid patch firmware addressing settings-persistence bugs introduced by the preceding update.
