iPhone 11 randomly shuts off and won't turn on

hi everyone, i have an iPhone 11 that randomly shuts off completely. It doesn’t happen often, I’d say it’s happened maybe 4-5 times this year so far. Whenever it does happen, the power button doesn’t work, i cant force restart it by pressing the volume and power button, and leaving it charged for an hour doesn’t work either. I left it to charge overnight and when i woke up it was pretty hot but didn’t turn on. The last time it happened to me it just came back after a while but now it hasn't come back. My phone is pretty old now and the battery health is probably 70 or under I’m guessing. I’m just wondering if anyone has found a solution or if i should just go to the Apple Store and replace the battery.

It’s a very simple solution. Please replace your battery. Apple recommends replacing the battery when its health drops below 80%. By your estimation you’re far below that mark.

Please take the advice Jeff Donald provided as a battery health of 70% means your battery is severely depleted. Worse things can result when using an iPhone with a severely depleted battery, such as the battery can swell, possibly damaging the phone beyond repair. And if the battery swells, the phone can become a fire risk. This simply isn't something you can put off.

Your battery needs to be replaced (iPhone Battery Replacement - Official Apple Support), but for a 7 year old model replacing just the battery probably wouldn’t be the best solution, because you would still have an obsolescent phone that can’t run any of the newer AI powered features of iOS. Consider putting the cost of a battery towards a newer model.
