Here are some troubleshooting steps to fix the problem of you iPhone battery losing charge overnight.
The scenario may be that you charge the phone fully to 100% before going to bed, but in the morning the device is down at 1%.
It’s most likely that your battery isn’t in great health, however here are some suggestions to try to troubleshoot this issue.
10 Steps To Fix iPhone Battery Draining
1. Background Apps Running: Check for apps running in the background: Go to Settings > Battery and check for apps that are using significant battery in the background. Close or delete these apps.
2. Turn off Background App Refresh: Go to Settings > General > Background App Refresh and turn it off for apps that are not in use.
3. Turn off location services: Go to Settings > Privacy > Location Services and turn off location services for apps that don’t need it.
4. Turn off push email: Go to Settings > Accounts & Passwords > Fetch New Data and turn off push email for accounts that don’t need it.
5. Turn off notifications: Go to Settings > Notifications and turn off notifications for apps that don’t need them.
6. Turn on Low Power Mode: Go to Settings > Battery and turn on Low Power Mode. This will reduce power consumption on your iPhone.
7. Check for software updates: Go to Settings > General > Software Update and check for any available updates. (This step could also resolve connectivity issues that you may have been experiencing).
8. Reset your iPhone: Go to Settings > General > Reset > Erase All Content and Settings. This will erase all data from your iPhone and restore it to its original settings. (This is a last resort to fix the problem).
9. Check the battery health: Go to Settings > Battery and check the battery health. If it’s below 70% and you’ve had your iPhone for a few years, it may be time for a battery replacement. This process could be expensive and you may just have to live with the problem until you get a new phone.
10. Use a different charger: When you are charging your iPhone, try a different charger plug and cable. Although all USB charger plugs send out 5v of power, the Ampage differs on different brands of charger. This can have a huge effect on whether your device is getting the correct charge in the first place.
Reasons To Avoid Charging Overnight
While most smartphones are now designed to stop charging once the battery reaches 100%, it is worth being cautious of the risks involved in overcharging your phone.
1. Overheating: The internal components of your device can be damaged if the device is overcharged. This damage is due to overheating issues. The tiny circuit connections inside can become faulty if exposed to prolonged heat.
2. Battery deterioration: Overcharging your phone can eventually reduce the capacity and lifespan of the battery. New smartphones use a voltage regulator which effectively slows or stops the charge when 100% is reached. This process is known as “trickle charge”.
3. Fire risk: In extreme and very rare cases, especially if using cheap adapters and cables, there is the risk of fire. If you do decide to charge your phone overnight, always leave it on a hard flat surface that is less likely to enflame if there is a spark or burn-out. Never have your phone in your bed with you while you sleep. Modern smartphones do have a built-in temperature sensor to stop charging if the device exceeds a certain temperature. However, to reiterate, the main fire risk comes from using faulty or cheaply produced cables and charger adapters.
