Since iOS 14.8, it all went downhill for me. My battery health dropped from 98% to 94%, a lot of apps are running in the background despite background refresh being turned off for them and I experience some annoying battery drain while the phone is in standby. Place your wireless chargers in a strategic manner around your house. As long as they are in your arm's reach, you can keep your iPhone on charge whenever not in use. For example, if you are I’m using 11 pro max a2220 model. i bought this four months ago at 99% battery health and 2 months of warranty remaining . After updating iOS 15 my battery health is dropping too fast 5 to 6% dropped in a single month . 3 days ago it was 90% now i saw today it’s on 89%. Please somebody tell me the solution my really worry about this issue 24 points. Dec 19, 2021 3:48 AM in response to theerapat259. I updated my iphone 13 pro to ios 15.2 and is experiencing a limited battery drain plus device heating is excessive suddenly. I don’t think it’s a good sign for a new device which is hardly 15 days old. Apple please look into it. I’ve had my phone for 8 months and my battery life has terribly decreased since ios 16. With the recent update, my battery health decreases by 1% per week 🙃. 13 Pro Max has been draining like crazy since the update, full charge to 40-60% overnight with zero activity and 10% background app usage. Phone is also extremely hot in the morning It's not real time. There are lots of reports that it can seem to stay at 100% and then all of a sudden it might drop to 97% or 96% at once or quickly in succession 97->96 within days. It updates where it might now show any kind of real time display of the underlying battery health. Reply. I used a “slow charger” with my 11. My 13 I used the same charger and for the first 3-4 months, no degradation. Switch to a fast charger, and this 11% degradation happened over 7 months. I don’t believe in the chargers affecting health like crazy in any way, but only after I switched to a fast charger did this begin to happen. If it’s a brand new device I think it’s a weird behaviour to lose 2% battery capacity in 2 weeks only. At this rate, after a year your battery would be worn at 50%, that’s huge !! My 7 Plus took about 6 months to drop from 100% to 99%, after a year I’m at 95%. Perhaps you should ask for a diagnostic to be sure your battery isn’t Tech reviewer Lon Seidman said that his iPhone 14 Pro is losing between 1% and 2% “every two weeks or so,” with it currently sitting on 88%. Several iPhone 13 owners on Reddit claim they have If you want your battery to last (lifetime not daily use), use slower non-wireless charging. 5watt charger via lightning is the best option for battery longevity. The more fast charging you do, the more heat. The more wireless charging or MagSafe charging you do, the more heat. The higher wattage you do (relates to fast charging), the more heat. V0qF.
