So I don’t use my ipad a whole lot, and noticed that even in standby most of the time, the battery depleted in less than a week. I found that by disabling iMessage that of course, it lasted significantly longer. I have a several year old iPad Air 2. By disabling iMessage, functionality really diminished. If you don’t use your ipad a whole lot, how long does the battery last and what type of ipad do you have? Reason for asking, if there’s a significant difference, I might consider upgrading. Thank you!
