Maybe you need a new battery for your phone

Have you met this situation that the battery power becomes less after charged one hour? This is something quite a few users complained about. While you may think that have to replace a new battery, that usually isn’t the case. So, what is causing this problem? Maybe the charging port is full of dirt or the cables may be damaged. Also, a software or hardware issue can cause this problem.  Those signs that your iPhone need a new battery.
Sometime it is the hardware issue, you can find a tutorial from iPhone 6 not charging with logic board repair.
The likelihood of your cell phone’s performance will not stay at one hundred percent forever. Your cell phone is likely to give a little more trouble, slow down or lose charge quickly as time goes by. The problems you may be experiencing with your phone may be caused by various things, including the need for a new battery for your phone.
The Signs That Your Phone Needs A New Battery
There are various signs that can tell you if your phone needs to get a new battery. You can tell that your battery needs changing if…
1. Your phone is dead: We mean completely and permanently dead. We mean that it just isn’t charging or able to come on. When there are no signs of power or life in the phone, even after it has been charged with a good chargers, you may just need to get a new battery.
2. Your phone only shows power when it’s on the charger or it doesn’t power on after it has been given ample time to charge up: This means that your battery does not hold the energy that it gets from the power source. If this is the case with your battery, you need a new one.
3. Your phone dies quickly: If you’re not playing games, listening to music surfing the web, using Bluetooth or doing something else that may be causing your battery to die. However, a battery that dies very quickly after it has been fully charged, may also be a classic sign that you need a new battery.
4. Your battery or phone starts getting very hot: It is actually quite normal for batteries to generate heat when charging, but their heat is internalized. Batteries that need to be changed, are those that generate or cause the phone to generate external heat.
5. Your battery bulges: The bulge in a battery means that the internal cells have ruptured and that simply means that the battery needs to be changed.

MacBook Pro Troubleshooting

The sleeker design with the thinner bezels, brighter retina screen, impressive audio quality, and fast performance, the new 2016 MacBook Pros prove clear departure from the previous generation. With last year’s 2016 MacBook Pro family proving to be one of the fastest selling laptops of the year, some unpleasant issues also emerged. Today we will introduce some of the most mentioned 2016 MacBook pro common problems. Since problems may be annoying, solutions can be expected. REWA LAB has been working on MacBook these days and we are honored to offer repair solutions appropriately to the situation you may get in.

Keyboard Issues

‘I have had my new MacBook Pro 2016 w. Touch bar for almost 2 weeks. The first week I really loved the 2nd generation butterfly keyboard but the feel has changed. It seems to me some buttons doesn’t feel like the other ones like they aren’t moving deep enough. For instance the Enter button. Cant really tell if its imagination.’
2016 MacBook Pro Common Problems
The keyboard of the 2016 MacBook Pros is totally different from previous-generation MacBook Pro models, and the new butterfly mechanism also appeared to be less reliable compared to older construction techniques. A growing number of customers are running into issues with the keyboard. For example, the new MacBook Pros’ butterfly mechanism keys are noisy, and there are also keys that make different higher-pitched sounds than other keys in some cases, etc.

Speakers Popping

When it comes to the question that what an Apple Mac can do when Windows 10 machines can’t do easily and completely legally? The answer should be running both Windows and MacOS. Apple’s Boot Camp makes it easy for MacBooks to run the Windows operating system. However, it appears that Boot Camp might be causing some serious and uncharacteristic audio issues for those who like to dual boot. Reports of loud crackling and popping noises increased day by day and some even reported a permanent physical damage to their speakers by the annoying pop.

Battery Life

Here comes the most frequent complaints leveled at the new MacBook Pros, battery life. Battery life is an important attribute for a laptop, and it represents a significant portion of the overall score. Users of the Touch Bar model, in particular, realize that battery life is falling short of Apple’s 10-hour estimates for Web browsing and movie playback. According to Apple’s data, the new Pros’ battery life will be determined by what you’re using the machine for. That has always been the case. However, things are different for the new MacBook pros this time because of three things: smaller batteries, a more power efficient screen, Intel’s recent CPU stagnation, and the 15-inch models’ mandatory dedicated GPU. Each element can be listed as a reason for short battery life.

Graphics Issues

Since new MacBook Pro models launched last year, a variety of graphics issues have been reported from some buyers of the new MacBook Pro models, ranging from brightly colored flickering, full-screen checkerboard patterns and screen tearing to corrupt textures and tearing. Although it is not entirely clear if the issues are a hardware or software problem, the result can be annoying. The graphics appear to act up most when users are completing intensive tasks and affected systems may subsequently experience unresponsiveness or a kernel panic, sometimes resulting in the MacBook Pro crashing.

What do you do when Galaxy S6 edge Plus turn on with black screen

Did you ever encounter with black screen after turning on your Samsung Galaxy S6 edge+? It’s a common issue on Samsung Series. When you press power button, the phone stuck with black screen. Yet the buttons were lightened up and the LED indicator was pulsing. So we know its just the screen that fails to wake up.

There will several common ways we will try to solve this problem.
1. Hold the power button and connect the charging cable
2. Boot to recovery mode and wipe cache partition
3. Factory Reset your Samsung Galaxy S6 edge+

However, if the screen still stays black, it may relate to hardware issue. That’s what we are going to share with you. Fix Samsung Galaxy S6 edge+ black screen – logic board solution.
Disassemble the phone first, and check the logic board. All going well. For Samsung devices, Black screen and other graphics issues are common problems, which are mostly resulted from the damage of OLED relevant inductors. Therefore, our initial judgment – the fault may be related to OLED circuit.
Measure the voltage value of OLED supply with Multimeter.
Normal voltage value on C9028 and C9026 means a normal voltage and normal status on OLED supply. Next, measure the diode value on each pin on OLED connector one by one. With no value measured on Pin 25 and Pin 27, we judge there might be an open circuit on relevant circuit related to the two pins. Since PLCD_MIPI_D0_N and PLCD_MIPI_D0_P of CPU are connected with Pin 25 and Pin 27 on OLED connector via Pin 3 and Pin 4 on F9013, our next step is to check whether PLCD_MIPI_D0_N and PLCD_MIPI_D0_P are in normal status. Let’s do it.
1. Removing the shielding cover on F9013.

2. Take out the logic board and attach it to PCB Holder for the detachment of F9013.

3. Measure the diode value on Pin 3 and Pin 4 of F9013, which is normal.

4. Continue to measure the diode value on Pin 25 and Pin 27. Judging by the measured value, circuit from OLED connector to F9013 is in normal status.

5. So the fault may be related to F9013. and we need to replace with a new F9013.
6. Align to the right place and solder with a new F9013.

Assemble the phone and test. Press power button to power on. The phone turns on with normal display and normal touch function. Fault cleared.

Hope you can solve your problem with our repairing guide. Any problems or suggestions please leave us a message. We will try to reply you in time.
