  • iPhone 12 Battery Upgrade: What You Need to Know

    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.

    iPhone Battery Capacity Increasing? Things You Must Know

    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.

    iPhone Battery Capacity Increasing? Things You Must Know

    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.

    iPhone Battery Capacity Increasing? Things You Must Know

    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.

    iPhone Battery Capacity Increasing? Things You Must Know

    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

    iPhone Battery Capacity Increasing? Things You Must Know

    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!

    Rendimiento –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.

    Why You Should Choose REWA Batteries

    REWA has its own battery production line. With different automation equipment applied during the whole core process, the battery assembling process is highly ensured. We utilize high-quality battery cells that will last a very long time – giving you day after day of great performance. Click here! take a closer look at the battery assembling process now!!

    Reparación Touch ID iPhone 7 Plus: Arreglar el cable roto del botón Home

    For iPhone 7-8P, 80% of Touch ID issues are caused by broken home button cable and we can fix the problem by jumping wires on the two layers of wires on the home button cable respectively. Which is very difficult especially when the bottom layer comes with many wires. And that’s when we bring you this new solution in our iPhone 7 Plus Touch ID repair blog today. With the help of the iPhone 7-8P Home Button Repair Socket Cable, we can fix the Touch ID problem in a safe and efficient way.

  • Reparación del Face ID del iPhone X que no funciona

    Reparación del Face ID del iPhone X que no funciona

    With the diffused application of Face ID on iPhone X – 11 series, Face ID failure also appears at a high frequency.

    As our previous Vídeo de desmontaje de Face ID has introduced, Face ID can be easily damaged and hardly repaired. If the problem is related to the flex cable, then it’s simple.

    However, based on statistics of REWA chip-level motherboard repair service, Face ID failure is caused by damage of the Flood illuminator/Dot Projector in most cases, which can not be repaired.

    La configuración de Face ID no funciona.

    Hoy queremos compartir un caso sobre ‘mover el iPhone un poco más abajo/arriba al configurar Face ID’ y mostraros cómo nuestros técnicos detectan el fallo en 3 minutos con la ayuda de los trucos de reparación exclusivos de REWA para la resolución de problemas de Face ID. ¡Empecemos!

    Face ID no funciona. Fallo de funcionamiento.

    El teléfono sigue enviando mensajes: ‘mueva el iPhone un poco más abajo/arriba’ durante el proceso de configuración de Face ID. Esto significa que Face ID no se puede configurar correctamente en el teléfono.

    Face ID no está disponible.

    Face id not available troubleshooting

    Ahora, vamos a averiguar cuál es el fallo paso a paso.

    Paso 1 Prueba del iluminador de inundación

    Based on REWA exclusive repair tricks, let’s start with the Flood Illuminator. There are two important Face ID parts whose behavior relies on the support of the Flood Illuminator. In our daily repair work, we can test the Proximity Sensor and the Ambient Light Sensor to confirm whether the Flood Illunmunator is working normally.

    ¿Por qué no funciona mi Face ID?

    Let’s make a phone call to confirm whether the Proximity Sensor is working.

    Durante la llamada telefónica, cubra la parte superior de la pantalla con una mano.

    We can see that the screen turns black immediately.

    Judging by this, the Proximity Sensor is working normally.

    how to fix face id

    A continuación, comprueba el sensor de luz ambiental. Ajusta el brillo de la pantalla al mínimo y luego sostén el teléfono bajo una luz brillante.

    With the screen getting brighter, we can confirm that the Ambient Light Sensor is also working normally. Judging by this, the Face ID failure is not caused by Flood Illuminator.

    my face id wont work

    Paso 2: Prueba las piezas de la cámara frontal

    Pasemos al siguiente paso de face id no funciona – Prueba las piezas de la cámara frontal.

    Abre la aplicación de la cámara y desliza el dedo hasta el modo Retrato. El fondo no se ve borroso, lo cual es anormal.

    why is face id not working

    Paso 3 Observación del proyector de puntos

    At the Portrait Mode, there is no flashing red light from the Dot Projector.

    But the Dot Projector should emit flashing red light in normal status.

    We can confirm now that the Dot Projector has malfunctioned.

    This is the fault that causes the Face ID to set up failure. And the problem cannot be fixed.

    why wont my face id work

    Consejos:

    Las tres partes (cámara infrarroja, iluminador de inundación y proyector de puntos) están emparejadas con el teléfono. El daño de cualquiera de ellas puede provocar un fallo en Face ID y dicho problema es irreparable.

    Right now, Face ID failure has become a common problem in our daily repair work.
