iPhone 12 mini Abnormal Battery Health Decline?

[The1andOnly]

My 12 Pro has been having battery issues for a few months now - I think right around the time of the first iOS 15 betas, but maybe before.

I had been watching battery health and for the first five or six months, it held firm at 100% - I was impressed, battery life was awesome. To that point, I don't think I ever even had the phone get warm to the touch. Then I started noticing some random battery drain issues - around the same time, my battery health display started tanking and within probably a 2 month period, dropped to 88% (my GF has a Xr that was purchased new & gets a lot more use, and her percentage is 89%). Since, it's held steady at the 88% mark now for around 2 or 3 months.

Since I started having battery drain issues, I also get overheating at times. Sometimes when indoors on wifi, inexplicably - but terrible overheating in sunlight. In fact, I can't use the phone in daylight & browse the internet for more than maybe 5 min before the screen starts dimming & will quickly get to the point you can't even see it in sunlight. It's really irritating, especially considering I came from an iPhone X that would overheat in daylight and dim the display a level (then stay there until it cooled) - and when I got my 12 Pro, I was really happy the issue seemed resolved (for the first 5 or 6 months). Now the phone is nearly useless in daylight.

5G vs LTE doesn't seem to affect the overheating. Seems like I can nearly completely drain the battery when away from my desk in about 6 or 7 hours of somewhat moderate use.

Anyone seen anything similar? I'm doing a backup and preparing to try a restore to see if it fixes the issue. Probably should have tried that a while back.

I, too, have noticed seemingly random (over-)heating, when not even charging!

My 12 Pro battery is horrible. Had it since launch and it's already at 85%. The 6.1 Pro is a battery killer, they put these "Pro" features in that phone but not a "Pro" battery like the Max has. Gonna try the regular 13 this time...I'm not an avid picture/video taker anyway to need the best camera. I'm thinking the 13 Pro will be a battery killer too with that ProMotion enabled.

This is normal. Batteries sometimes stay for long, quickly degrade and then stay for long.

very fast degrade... and my last 10 days statistic is gone for some reason...

My launch day mini 12 is at 90%… I am so glad I upgrade yearly.

I abuse my batteries and don’t baby them, I let the next owner have the fun of a reduced battery capacity hehe.

My launch day 12 Pro Max is still at 93%. I’m not upgrading so at this point, I’ll use Apple Care+ when the battery drops below 80%. My phone is in low power mode pretty much 24 hours a day, so my phone will last me all day until I put it on the charger at night. I use the 5W brick from my previous iPhones and saved my 30W brick for emergencies or when I’m desperately trying to hurry up and charge it, which is rarely. I’ll upgrade next year to the iPhone 14 and hopefully Apple have better batteries in the 13 and 14 series.

Now down to 95%. Terrible!

EDIT: Launch day 12PM.

94% now; dropped while upgrading to iOS 15.

Can I still add AC+?

EDIT: @TheYayAreaLiving, whatcha laughing at?

 

[Major774]

Yes… down to 89% (launch day phone), been working hard to knock it down since launch day.

Got my 13 mini coming on Friday, so good luck to the next user of this 12 mini hehe.

iPhone 12 Pro - 85%, Apple refuses to do anything so I'll have to upgrade...luckily I'm on the iUP anyway

My iPhone 12 is at 100% and my wife’s 12 Mini is at 93%. Both purchased on same day: 8th Feb 2021. We both are heavy users so usage is roughly same. Her phone’s battery health started dropping since last month and 1% lost every week. I got AppleCare Protection Plan by calling their CC and when Wife called in they said AppleCare Protection plan has been discontinued. She has to take either AppleCare+ or disconnect the call. 😂

Wife’s 12 Mini is now down to 88% and my 12 is at 98%. Apple is using extremely poor quality batteries in their overpriced devices. Not even including a decent charger. Feels violated.
