Аккумулятор iPad Air 4 быстро разряжается в режиме ожидания с подключенной клавиатурой Logitech

The battery of my iPad Air 4 has been draining power quickly in standby mode since I bought it. A third‑party Logitech keyboard is connected to the iPad. With the screen locked, it can use about 10 % of the battery overnight and about 10 % during the day. If you disconnect from Wi‑Fi and enable Airplane Mode, the battery holds its charge better and doesn’t drain as quickly. What can be done about this? After all, the iPad shouldn’t be draining so much battery with the screen locked.

Given that an iPad will be performing background housekeeping tasks whenever it is not being actively used; 10% battery utilisation overnight, while idle, is not at all unexpected - and perhaps reflects a realistic average.

When intentionally disconnected from WiFi as you describe, all background system synchronisation activity with iCloud, automatic device backup, scheduled email retrieval will be suspended - reducing system activity and consequently reduce battery use while idle.

In summary, on the basis of your description, your iPad is operating normally and as expected.

Should you wish to manually inhibit background tasks, simply enable your iPad's Low Power Mode:

Settings > Battery > Low Power Mode - set to ON

Be aware that inhibiting background housekeeping will impact device performance - and potentially inhibit automatic backup and synchronisation with iCloud - these services ultimately being something upon which you may rely.

Automatic email retrieval can be inhibited - such that email will only be downloaded when accessed - reducing battery utilisation:

Settings > Apps > Mail > Mail Accounts > Fetch New Data > [Fetch] - set to Manually

Similarly, while you should seriously consider the implications, you can suspend automatic iCloud backup:

Settings > [Your Name / Apple Account] > iCloud > iCloud Backup > Backup This iPad - set to OFF

Ensure that you have updated your iPad to the most recent version of iPadOS - at the time of writing, for your iPad Air4, is iPadOS 26.7.1 or optionally iPadOS 27.0.1.

If your iPad as not performing as expected, try a forced-restart - as this will often clear an isolated or post-update software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

If the problem persists after performing the restart, it may be necessary to reset your iPad settings. While this reset will not cause any loss of data, as a precaution, it is always wise to ensure that you have a current iCloud or iTunes backup before performing the reset:

When you are happy to proceed, you can perform the reset from iPad settings:

Settings > General > Transfer or Reset iPad > Reset > Reset All Settings

If the problem still doesn’t clear, the next step is to reset the iPad to factory settings:

Otherwise, you would be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively and perhaps easier, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

Thank you for the answer. But I had to say that it can use more than 10% overnight if the wifi on and use about 10% if I turn on the Airplane mode
