We already subconsciously want to charge our devices to 100% before being away from the power source for a long time. Alas, this mark is not always achievable. At one point, you may find that your iPhone is not charging to 100%. Is it really broken or is it something else? Is it possible to fix this situation? We'll tell you why this happens and what you can do.

Reasons Why iPhone Doesn't Charge to 100%
- "Optimized charging" function activated.
- The "USB accessories" option is disabled.
- There are problems with the power supply or cable.
- Software malfunction.
- Hardware failure of the iPhone itself.
Now that we have learned the possible causes of the problem, let's think about how we can deal with them.

Not original memory
The reason that the mobile phone cannot be fully charged may be due to a non-original charging device.
It is advisable to charge Apple smartphones only with the original cable, since it is equipped with a special chip that is responsible for authenticating the mobile phone. If the device does not see this chip, it does not accept the charging wire. Among the main consequences of using unknown charging are:
- Damage to the cable.
- System board failure.
- Damage to the memory connector.
- Battery swelling.
When you charge your iPhone with an unknown Chinese cable, you can break it. Bad chargers are unable to protect a smartphone from severe voltage surges, so the chances of its early failure are as much as 90%.

Every user may encounter the problem when the iPhone is not fully charged. If we are talking about a smartphone that has been in use for more than a year, then the cause of this problem may be a natural loss of battery capacity. In this case, the only solution is to replace the battery.
Enable USB Accessories option
If you use a power bank or other external device to charge your iPhone, and the smartphone screen has been locked for more than one hour, charging may automatically stop. To prevent this from happening, set the USB accessories switch under Settings → “Face ID and passcode” (or “Touch ID and passcode” depending on the device you are using) to the On position (details).
Natural loss of capacity
During use of the device, natural loss of battery capacity is, unfortunately, inevitable. After 500 full charging cycles, the total battery power is reduced by approximately 20% of the charge. There are certain factors that contribute to early capacity loss. Among them are:
- Violation of the temperature regime while charging the smartphone.
- Using a non-original device to charge a smartphone.
- Failure to comply with recommendations regarding the depth of discharge.
If you charge your mobile phone correctly, the loss of battery capacity can be delayed by about two years or even more.
Checking the power adapter, cable and port of the iPhone itself
Charging problems can occur due to a faulty power supply, charging cable, or even dust getting into the Lightning port. That is why, if a problem arises with the battery being fully charged, it is worth checking the accessories for obvious damage, and simply clean the port of dirt. But this work must be done carefully, preferably with the help of compressed air. If, upon external inspection, the cable and adapter do not seem damaged, and charging is too slow or does not occur at all, then you can try using a different set of accessories. This will help determine if the problem lies with your accessory.

Discharge depth and battery charging cycle
It is not recommended to completely discharge the smartphone battery, as this has a very bad effect on the capacity of this component of the device. When it is completely discharged, its useful life is necessarily reduced. You can trace the following dependence of the charging cycle on the total depth of battery discharge:
- If the device is completely discharged, the total number of charging cycles will be 500.
- When half discharged, the battery will withstand one and a half thousand charging cycles without any loss of capacity.
- When discharged by 25%, the total number of charging cycles is 2500.
- If the battery is charged at 1, 2, 3, 4, 5 and 20% charge, the number of cycles will increase to 4500.
Thus, the smartphone will last much longer if it is less often subjected to complete discharge.
How to reboot iPhone?
1. Press and release the Volume Up button.
2. Press and release the Volume Down button.
3. Press and hold the screen lock button.
4. When the Apple logo appears on the display, release the button.
It must be said that this reboot method is available only to relatively new models, starting with the iPhone 8 and all subsequent ones. Here's what you need to do on older models:
- If you have an iPhone 7, iPhone 7 Plus, or iPod touch 7th generation, you will need to press and hold the screen lock button and the volume down key until the Apple logo appears on the display.
- If you have an iPhone 6s or earlier models, then you need to press and hold the screen lock button while pressing the Home button until the Apple logo appears on the display.

We reanimate the battery
Battery problems are familiar to all cell phone owners, iOS or Android, it doesn't matter. Over time, the battery material begins to “deteriorate”; the more charge-discharge cycles, the less the electrical capacity becomes and the faster the smartphone runs out. Usually the “death” of the battery occurs after 3-4 years of operation, the number of cycles exceeds 500-700 and problems begin. One of them is that the iPhone can only charge when turned off. Now, in order, what is worth checking and where to put your hands.
Having checked the charger and the accessories adjacent to it, perhaps even replacing them with new ones, deleting all unnecessary applications and turning off the smartphone altogether, but still, the iPhone only charges when turned off, then we move on to a more complex stage.
The ideal option would be to purchase a new battery and install it to replace the damaged one (I will attach a video on how to replace it), but this is not always realistic due to circumstances and the user’s lack of repair experience.
The only option is to leave the unfortunate iPhone turned on all night; this is unlikely to help restore the device and the battery in it, but it’s worth a try.
It is advisable to do the resuscitation of a non-removable iPhone battery not at home, but even better, it would be to give it to experienced people who know a lot about the safety and high-quality repair of mobile phones.
Tips for long-term storage of phones
If you want to leave your smartphone alone for a while, then this must be done according to all the rules. Otherwise, there is a risk of reducing the battery capacity, which will negatively affect the use of the gadget in the future. The following rules must be followed:
- charge the device no more than 50% - a 100% charge will negatively affect the performance of functions;
- turn it off completely - otherwise, after a while the battery will completely run out;
- maintain a certain temperature - should be 25-30 degrees, not higher.
If you do not use your phone for more than six months, then constantly recharge it by at least 50%. Compliance with recommendations will preserve the functionality of the gadget for several years of storage.
Why does the new iPhone take a long time to charge?
Let's look at the main reasons for long charging times: Power adapter with low power. ... Apple allows the use of stronger chargers, for example, from the iPad, but you must use only original accessories. A non-original Lighting cable, like an adapter, can charge an iPhone for a long time.

Enabling Power Saving Mode
When using the energy saving mode, the battery life of the device without recharging significantly increases. You can switch your phone to low power mode if your iPhone's battery is low or if you need to use your phone for a long time without charging it.
Go to Settings > Battery.
Enable energy saving mode.
In power saving mode, background activity is limited and only necessary actions are performed, such as receiving and making calls, receiving and composing emails and messages, accessing the Internet, etc.
Note. If your iPhone automatically switches to low power mode, it will return to normal mode when it reaches 80% charge. In Low Power mode, some tasks on iPhone may be slower than usual.
