IPhone 13 battery drain and heating problem

Mine is doing all of that also. I have done everything listed here to save battery. It’s overheating in my house that I have a comfortable 73° I go to bed with 100% battery I wake up and it’s down to 40%. Something is definitely wrong with these I 13 phones. I’m seeing too many issues all over the Internet.

My iPhone 13 battery is draining sooo fast 🥲🥲 what should I do

Even tho my battery health was at 88% and I had already rebooted my phone and made sure no aps were running in the background and no power drains (ie location services turned off), I replaced the battery and updated the IOS and it fixed the issue.

My wife’s iPhone pro max 13 iOS 16.6

on an airplane (just happened) overheated and wouldn’t cool down after shutting down. It was too hot to hold the phone. The battery was drained from 90% to 3% in minutes.

Protect & Prolong life of your iPhone's Battery:

1. About the battery usage on your iPhone, iPad, and iPod touch ...
2. Batteries - Maximising Performance - Apple (IN)
3. iPhone Battery and Performance

Try some of these options too.

1. Avoid Screen Mirroring
2. Put on Low Power Mode
3. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
4. Put Auto Answer Off
5. Disable Push notifications for apps you do not use often
6. Keep your iPhone Face down to prevent notifications to light up screen
7. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
8. Manually lower brightness from Control Center
9. If you Want to watch continuous Video. Stream it on TV or a Monitor
10. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
11. Location services to be allowed only while using the app
12. Set your iPhone to fetch email and calendar data from internet less frequently
13. Turning off Background App Refresh 
14. Charge before it drops below 20-30%
15. Try connecting to trusted Wifi where ever available in stead of Cellular
16. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
17. Switch off Wifi & Bluetooth while in Roaming or Not in Range
18. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
19. Periodically Check your Battery Health (Settings > Battery > Battery Health)

now the phone heats up too

I am not aware of the ambient temperature in which you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...

Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.

Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.

Have you tried the encrypted backup and restore?

The links appear again below:

Link for how to Back up and Restore: Back up and restore your iPhone, iPad, or iPod touch to your Mac or to iCloud - Apple Support

Link for putting iPhone in DFU Mode: If you can't update or restore your iPhone or iPod touch - Apple Support

Please report back wether performing the above process made the battery drainage worse, fixed it, or if you noticed no change at all. 

I hope this is helpful. Good Luck!

OH MY GOD!!! How old is her phone? You probably need to replace the battery if it’s over 2 years old—my iPhone SE 2nd generation has just started doing the same thing the past month, especially while riding in a car. A strained battery is the first cause of this.

What you have to do is set your phone to turn off auto more quickly. It’s in settings. Plus turn it off regularly if it’s not doing it on its own. You’ll still get your texts and the phone will ring normally. Check your battery status in settings Menu as well.

Then it is very likely that your iPhone has a strained or worn out battery, if you have had your phone for over 2 years. You will need to replace the battery.

My iPhone battery is discharging quite quickly since I installed iOS update 16.4.01. Nightmare.
