This has been an ongoing problem for me for a couple of years. If I let my iPad charge to 100%, I get the plug in symbol. If I unplug and plug back in again, it will start up but will go dead within minutes. I have tried resetting, restarting, turning the airplane mode on, turning off the Bluetooth and none of this has worked. The only work around I have found to work is to try to keep the iPad on long enough to connect to YouTube and to play a video until it gets below 100%. This can take up to an hour of time, plugging and unplugging before I get a good connection that sticks. I have contemplated getting a new battery, but am not sure if this will fix the problem and I really don’t want to have to pay $100 to try it. I am curious if anyone has had a similar problem and has replaced the battery.
