iPad battery help
Coming by again to ask this, but is my iPad battery doing OK? It's an iPad Pro 9.7 inch from 2017 with about 4 years put into it. For the most part, I have taken good care of the device (aside from accidentally leaving it somewhere hot for 5 minutes) and I'm wondering if it's just time to schedule a repair since it's a still-supported iPad or to replace it with a newer one entirely. I have since done everything I can to maximise battery usage, such as setting mail from push to manual-fetch, disabling all notifications unless for necessary apps, disabling background refresh, lowering brightness, disabling Airdrop, etc. It used to be able to get 10-12 hours of use each day from 80-30% mainly 6-8 hours on average since I use this iPad with a lot of heavy CPU/GPU intensive apps, programmes and games, and now it gets about 4-5 hours on average. So far, battery isn't too damaged as the UI still runs smoothly and nothing has any major performance issues, most if not all high-intensity apps run without major performance discrepancies. Could this just be wear and tear for having it for so many years, poor app optimisation for this model? or is there an actual battery problem going on?
