Your iPhone is Too Warm As mentioned, heat is one of the quickest ways to damage and decrease your iPhone's lifespan. If you're charging your iPhone in a particularly warm location, the iPhone will automatically stop the battery from charging past 80%.
Set a Charging Alarm to Stop Android Charging Above 80%
Install the Charge Alarm app from Google Play Store and launch it on your phone. 2. Next, enable the toggle for the Full Battery Alarm and set the desired battery value to start it.
Change your Battery Care settings
Your Battery Care settings may prevent your phone from charging to 100%. This is a safety feature in order to increase the battery's lifespan. If you would like to remove this setting you can set the "Always" mode in the Battery Care settings to OFF. Set "Always" mode toggle OFF.
Uninstall Third-Party Battery Apps
These apps may be the major culprit behind your Galaxy phone not charging after the 85 percent issue. They work identically to the 'Protect Battery' function and artificially limit your phone's charge to 85 percent only. You don't need such apps on your phone.
iPhone only charges to 80%?
If you notice your iPhone stops charging at 80%, that's actually a feature called optimized battery charging that helps reduce battery aging. But it is possible to turn off the feature. Head to the Settings app > Battery > Battery Health > and toggle off Optimized Battery Charging.
Why Does iPhone Not Charge Over 80% Even When Plugged in? Starting iOS 13, Apple introduced a new battery optimization feature called Optimized Charging. Enabled by default, it slows down the iPhone charging to maintain the battery health. And often, it holds it at 80% to slow the rate of battery aging.
For example, charging will pause when the battery level reaches about 80% at night. Before you get up, charging will resume to fully charge your phone. This prevents your phone from being charged while its battery is already full, thereby effectively prolonging the lifespan of the battery.
Defects at the charging port create loopholes when charging. Dust particles or water spills cause bugs at the charging port. Their presence in the metallic charging port can hinder your battery percentage from increasing. A close look allows you to spot corrosion or dust at the charging port.
Your phone might not be fully charging because of many reasons. These are Battery problems, faulty motherboard, dirt on the charging port, charger issues, and when the mobile software needs an update.
With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations.
These are all fine features, but one thing that Li-On is not really keen on is being reduced to 0 percent and then back up to 100 percent each day. Apple recommends, as do many others, that you try to keep an iPhone battery between 30 and 80 percent charged.
It's true that charging above 80% can shorten total lifespan, but the effect is very small. If you don't charge it to 100%, you run the risk of not having enough charge for the day. If your cell battery runs to dead, it ages the battery much faster than charging above 80%.
Try using a new Samsung cable. One of the most common causes of charging problems is if the charging port is clogged with dirt, dust, or debris. Dirt or lint can build up inside the charging port and prevent the charging cable from engaging properly with the charging contacts inside the port.
Check & Clean Your Charge Port
Check whether the port is clogged with dirt or debris, for starters. Even a filthy port might cause problems with charging. Using a brush, you could remove it. Excessive use can also wear out ports and you might find corrosion in your charging port.
Fast Charging Technology: Some phones have a fast charging feature that allows you to charge your phone quickly. However, fast charging can generate heat and cause damage to the battery. To prevent damage, your phone's BMS may stop charging your phone at 80%.
Yes, you should turn off optimized Battery Charging if you want it to charge fully. However, if you want your battery to have a longer lifespan and avoid micromanaging it, it would be best to turn on optimized battery charging.
If your phone won't charge, turn it off again and use a toothpick to gently scrape or pull out any debris in the port. Be sure to do this under a bright light so you can see what you're doing, and work slowly so the toothpick doesn't break.
This message appears on your Lock Screen and in Settings > Battery: "Charging On Hold. Charging will resume when iPhone returns to normal temperature." To resume charging your iPhone as quickly as possible, move it to a cooler or warmer location, or if your iPhone is in use, put it to sleep.
Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It's not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.
Yes, in fact, most people do just that as it is a convenient time to charge. The battery cannot be over-charged.
While fast charging can increase the rate at which your battery loses capacity, its actual impact is only about 0.1 percent more capacity lost than without using fast charging.
