User level: Level 1 (4 points)I left my iPad M5 Pro uncharged for ten days. Today, as I checked, it was completely discharged. Has my battery been badly hurt?

Your battery has likely not been damaged...all should be fine. Charge the iPad up and monitor it yourself for issues. We can't help you with that aspect.
That being said, it's good practice NOT to continuously run the battery down to zero and leave it in that state for long periods of time.

Lithium-ion batteries in today's devices have a built in "buffer" or reserve...even though the battery states it is at zero, it's not really at zero as there is built-in "buffer". This "buffer" will last only so long however and when the battery is truly dead (at zero with NO reserve), this is what causes the damage.

Your "Battery Health" will in fact degrade over time, regardless of whether or not the iPad's battery is run down to zero battery or not. Batteries degrade over time and use, just like your car's battery. So definitely don't expect the your "Battery Health" to remain at 100% indefinitely.

Hi @SergZak, thank you for your reply. I have charged it and it charged fine. Working all good. Only I was concerned if my battery would have taken a big blow due to this incident.

Thank you! So I shall keep using it normally and hope that my battery health should remain 100%.
