Battery usage not showing?

So to followup, it's the battery. My local Authorized Service depot, tried 2 more batteries until the 3rd one would give battery usage stats. The Apple Store "genius" was only interested in selling me a refurb for $329. Be persistent and take it somewhere else that knows how to diagnose these complex issues.

Hi. Seems like you're on to it. I changed the battery to a cheap eBay one and all was fine until I updated to iOS 10.3.1 even the battery life was fine until the update. After the update battery brain was crazy. Full dfu restore and still the same. I'm after finding a genuine 6s battery online from a broken phone. My question is this. When I swap out the cheap battery for the real apple one do I need to restore the phone again or will the phone know it now has the real one in it ? Really hoping this works as the battery life is terrible. Cheers. Look forward to the reply

I've gotten the phone taken apart by tech repair guys that do micro soldering. The u2 ic chip is fried. It can have numerous symptoms. A short in a charger lead fried it. Voltage fluctuations caused it.

Fake charging , not charging a totally dead battery , rapid battery drain. Very common once you know symptoms and what to google.

90 euro to get it replaced. In a repair shop. Not apple.

Happy to have it sorted

I have the same problem on a 2 weeks old Iphone 7 Plus 128 GB running IOS 10.3.2.

Since I bought the device it never displayed any battery usage info.

The battery life is more than ok, I have ~5 days between charges with very light usage (1-1.5h/day).

Based on all the threads I have read since the latest iOS release battery drain issues are affecting 60% of iPhone users. And Apple has still to admit they messed up in the latest release or to provide any type of solution to any of their customers.

After 3 complete discharge / charge cycles the batery usage info was displayed all of the sudden. So, basically, after the 4th charge since the phone was bought it started displaying the batery stats, without me doing anything to it.

In regard to the battery life, I'm quite satisfied with it, I've gotten upwards of 110hours per charge with ~8 h of usage and the rest of it stand by. The max I've got so far is 147.5 hours (9h of usage and 138h of stand by), roughly 6 days.

Mobile data is always on, so is WiFi.

I have a 6s I recently replaced the battery and now I get about 20 hours standby and 5 hours usage without the details of which apps are drainging the battery. Apple thinks they’re sneaky, if you use a battery or screen that isn’t Apple brand then the firmware is designed to glitch your phone.

If you say that the battery is new, has it been replaced recently, or is it the still the first battery?

Did you try to set the phone back to factory settings, without using any backup and check the battery life after that?

Use iTunes to restore your iOS device to factory settings - Apple Support

If Apple or an Apple Authorized Service Provider replaced the battery, bring it back to them, replacing the battery is also covered by a short warranty period.

Downloading the official 10.2. might also help, follow the steps given to you when you joined the test program to remove the beta.

Using iTunes will make sure that a complete firmware package is downloaded, checked and installed. Upgrading via Wi-Fi will only download a smaller package and certain parts of the older firmware version may not be changed or updated.

You're welcome. Good Luck 🙂
