Brand new iPad A16 battery draining to 0% overnight

Before returning your iPad to the retailer for replacement, there are some steps that you may wish to try first...

If your iPad is not operating as expected, try a forced-restart - as this will often clear an isolated 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 might be well 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:

If Apple Support diagnose a fault, or are unable to identify a problem, seeking exchange of your iPad from your retailer is the next logical step. Alternatively, you might visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad - and you can explore your available options via Apple:

Is it normal that I just bought my ipad a16 from Powermac last week and after I charged it and left it at 100% at night, it was at 0% when I woke up the next morning?

Possibly normal. A new device has a lot of “housekeeping” after it is activated, building search databases for example. If the problem continues then there may be a hardware problem.

However, you should be charging overnight.

The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term, is to charge the device overnight, every night leaving it powered on. Once it reaches full charge all energy use until you unplug it will come from your external power source, thus saving battery charge cycles. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

Take it back.

Return it for a refund A.S.A.P.‼️

Is there a genuine Apple Retail Store near you?

I never heard of "Powermac".

Good luck! 👋🏼😉
