Four Tips for Maintaining iPhone batteries?

Regularly checking battery information can only help us understand the battery’s degradation and cannot extend the life of the battery. In fact, the battery can also be maintained, but you didn’t pay attention to these problems before.

Avoid using poor and unoriginal charging accessories

The original is not necessarily the best, but it must be the safest. The same is true for charging accessories. During charging, the mobile phone is impacted directly. Using pirated or unauthenticated chargers and data cables will cause a certain extent or irreparable damage to the device. So you should not use an informal accessory because of the price, which gives you a huge loss.

Pay attention to the temperature of the environment in the device

Some friends may have encountered such a thing. You take the iPhone to run outdoors on a cold winter night. The phone will suddenly prompt you that it can’t work under such a temperature. The iPhone battery has some requirements for temperature, and the most ideal working environment between is 16 ° C to 22 °C.

If your iPhone is running in an environment above 35 ° C, the consequence may be permanent battery capacity damage. The so-called permanent damage is unable to recover. Maybe you will encounter the “unpleasant full power”. Using iPhone in extremely cold environments will temporarily compromise the performance and shorten the battery life. When you return to the normal environment, the battery will automatically recover.

Under the right conditions, update your system

In fact, the official version of iOS includes optimization of battery usage and battery life. The latest version of energy-saving technologies is generally better than previous versions, but it is recommended that you update according to the actual situation. For example, updating an old device to the latest system can cause more harm than good, so updating your system to the new version under the appropriate conditions is the best choice.

Storage equipment to ensure power

If you temporarily do not use your iPhone, you must pay attention to keeping the power of about 50%. Because when the battery loss is low, it may fall into a depth discharge state, resulting in damage to the battery. Conversely, the device has been in the state of charge and is placed for a long time, which will induce permanent battery degradation. So when you choose to place the iPhone for a long time, you must not only choose a suitable environment but also maintain its power.

iPhone 12 Battery Upgrade: What You Need to Know
According to reports, Apple is planning to equip iPhone 12 with a custom battery protection module that is nearly 50 percent smaller and thinner than the battery protection circuit in previous iPhones.The smaller module could free up some internal space in iPhone 12 models, potentially paving the way for a slight increase in battery capacity. The smaller module would be supplied by South Korea’s ITM Semiconductor.

The battery capacity design of each generation of the iPhone is different. Although new models are gradually increasing the battery capacity year by year, the increasing rate is not high enough.

Android phones like Samsung’s galaxy series and Huawei’s mate series, by contrast, are equipped with larger and larger battery capacity.

As far as we know, the battery life of a smart phone depends not only on the battery capacity, but also on the hardware configuration and system optimization of the phone.Unlike the Android system, the iOS system is very strict about APPs’ self-starting, linkage wake-up, etc.. All iOS apps are designed in compliance with Apple’s requirements. And that’s why iPhones can run smoothly with guaranteed battery life with relatively small battery capacity.

Why iPhone Battery Capacity Is So Small

As smart phones becoming more and more powerful with larger displays and more power-hungry camera modules, battery capacity design also becomes more and more important and demanding for manufactures.

According to data in the above figure, Apple has been strictly controlling the thickness and size of the fuselage of iPhones. And the thickness of 8mm has not been launched until 2019. With the change of screen ratio and the increase of system functions, the battery life of newest iPhones is even worse.

Apple has always been pursuing a better user experience. In order to add better vibration feedback-3D Touch function, a larger volume Taptic Engine linear actuation motor has been added. The cancellation of the 3.5mm headphone jack since iPhone 7 series is also aimed to allow more space for the new Taptic Engine.However, increasingly complex internal designs contribute to insufficient overall space and therefore result in a relatively small capacity battery.

iPhone Battery Common Issues & Causes

Common Battery Issues

Battery drops sharply.

Charge the phone and the battery percentage increases instantly. However, the battery percentage also drops sharply during usage.

The battery percentage is 0 and the phone turns off automatically. Restart the phone and we can see normal battery percentage. The phone also runs normally.

There is no significant battery drop. Yet the phone keeps heating and battery drops gradually.

Common Causes For Battery Issues
- Malfunction of PMU.
- Battery aging.
- Overcooling/overheating environment.
- Jailbreak leads to system instability.
- Power-consumption programs running; high-speed flowing of data; CPU continuously running under high load.
Differences Between Aftermarket Batteries And OEM Batteries

Aftermarket Batteries are different from OEM batteries in the three aspects: Price, Value, and Performance.

Price – Aftermarket batteries offer customers a lower price than that of OEMs. In fact, on average customers choosing aftermarket batteries end up saving up to 90% in the cost of batteries comparing to those choosing OEMs.

Value – OEM Batteries offer consumers a greater value in terms of compatibility. However the aftermarket batteries have great capacity and longevity. The higher the capacity rating, the longer your battery can last between charges. More capacity equals more runtime. More runtime equals better value!

Performance –Our phone does not care whether you have a big brand name on the battery or it is a generic aftermarket battery. What really matters is how long will the battery last and how well will it work.

Top Reasons to Opt for REWA Batteries
All mobile phones depend on a lithium-ion battery to operate.

Batteries are rechargeable and must be plugged in after the drain for phones to operate.

Usually, a lithium-ion battery in use should last between 2 to 3 years.

Nowadays, all mobile phones are using lithium-ion polymer batteries.

A lithium-ion polymer battery is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte.

The two important parts of a mobile phone battery are the battery cell and protection board.

Damage of the battery cell or the protection board will result in your mobile phone not charging/turning on.

And the battery capacity will affect the standby time of the mobile phone.

Overcharge, over-discharge, short-circuit, etc. will result in a swollen battery cell.

Protective start-up failure caused by poorly performed protection board may result in battery damage, smoking, fire, explosion, etc..

Notice:

A production-finished battery cell should be protected from short-circuit, high temperature, impact, drop, overcharge, over-discharge, etc..

Users should use chargers from a regular manufacturer to charge the phone (the charging voltage should not exceed 4.2V).

And the operating temperature should not exceed 45℃.

Don’t put the battery together with conductors like keys to avoid external short-circuit.

Protect the battery from collision, external physical damage such as drop and squeeze, impact, overcharge, and over-discharge which are probably to cause explosion.

It’s necessary to choose high-quality batteries.

Low-quality batteries do have bad effects on your phone, even your health.

Treat it carefully when you decide to replace your battery.

Harm Effects of Low-Quality Batteries

Small capacity means short service life.

Short battery cycle life leads to a faster charge decay.

And that’s why the batteries need to be replaced frequently.

Battery volume indication error, insufficient discharge, and cliff-like power drop may lead to auto power-off.

High internal resistance increases the heat and power consumption.

What’s more, the increasing temperature brings potential security risks.

Low-quality protection board may cause identification failure, connection failure and power indicator error.

Protection board temperature measuring error makes the phone unable to have an accurate response to temperature changes, which can also damage the phone.
