iPhone X constantly restarts then battery shows 0%!

iPhone X constantly restarts then battery shows 0%!

I have recently updated to iOS 12.3.1 last week and during the past 2 days, my phone has been restarting, then the battery would show that it is at 1% on the status bar and 0% on the wake screen. There is even that lag usually when the battery drops to 1% which is normal for the X and 8 I believe. If I keep using the phone or charge, it will either reset again or the battery would jump up to where it normally is. The battery percentage wont go to 2% if I keep it charging because 1% is not the actual percent left. The only thing I can think of is installing the update with just under 50% battery. I have reset all settings and once that did not work, I have restored the phone from a previous date. Any assistance or tips is appreciated before bringing in to repair or even replace the battery.

"Unless the phone was dropped, repaired or came into contact with water, it sounds like you may have a defective battery or an issue with the charge circuit.

To be certain, use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows). Anything less than 70% of design capacity will require replacement.

You can also use the Battery Health Diagnostic (Settings\Battery\Battery Health (Beta)) in iOS 11.3 and above. It will tell you what the health of the battery is. Once the battery reaches below 80% of design capacity, iOS will throttle performance if the phone experiences an unexpected shutdown. You can read more about this at the following Apple Support page (https://support.apple.com/en-us/HT208387).

If you have access to a USB Ammeter, you could use that to determine if the phone is really drawing current when it says it's charging."

For me the issue looks like that: it showes 0% remaning even when connected to the charger, phone resets itself and 3uTools doesn't even see the battery, it says it doesn't charge the phone and every otehr information about the battery is unknown. Is that the problem with the battery or is it any known hardware issue?

"[SOLVED]

Last Year in 2019 i had an issue. I gave my phone to my mother and she handed it over to my cousins and siblings to have a look. I dont know what they did to it. Phone got switched off. It was Eid’s 1st day and all the markets (repairs) were closed. We don’t have official apple store in Pakistan as of yet (May 2020) despite so many users.

Phone was blank and wasn’t turning On at all. I plugge-in the charging cable and it started to go into a Booting Loop (only Apple logo show on screen and it turned off again).

I called a friend (a repair guy) next day (Eid’s 2nd day) and he open the phone. We found out that the phone was dropped and one battery was disconnected from Board.

Now today (18-May-2020) my phone was in my shirt’s pocket and shirt dropped from hanger and phone hit the floor. when i checked, it said 0% battery. I plugged-in the charging cable, it caused a taptic vibration we feel when charger connects, BUT now sign of charging shown on the battery icon. It keeps restarting after some time. Sometimes 1 minute, Sometimes 15 minutes. Wifi is turned On and connected. Whenever i receive heavy data through internet, it turns itself off.

Tomorrow i ‘ll go to the repair guy and ‘ll update u guys accordingly. Hopefully, its again battery connectors.

Sorry for late update. I visited the repair guy, he opened it up and found that connector (jack) of one of the battery (as iPhoneX contains 2) was lose. He simple pushed it in and turned the iPhoneX On. All went well. Upon successful turn-on i check battery health its 87%.

Hence, i conclude that the battery connectors in iPhoneX are not perfect fit, as a major drop can put ur life in much worry."

Yes, Apple Store has replaced the phone because the guy pressed the front and back of the screen and felt maybe the battery was expanding.

The design capacity of my phone battery shows 0% and full charge capacity is NaN as per coconutBattery does this mean battery is damaged?
