Baseus iPhone Battery Review

This one some of you might hear the name before.
Baseus - one of the famous brands in accessories of iPhone.

Baseus iPhone 7 battery 

Packing is nice. Installation manual and tools provided.
The size of the battery is totally the same as the original. It makes me wonder again. 

As usual, I'll use PC app to read it.
This battery really shows the extra capacity.
Unlike the "previous battery review which no show extra capacity than the original.

To be fair, I conducted the test with few rules.

How we test the iPhone battery?

1. Restore the iPhone and latest iOS 12.1.2. No any third party app installed. Clean. 
2. Of course, the iPhone must be in very good condition. No issue and fully original parts. No repair before.
3. Empty the power and charged back 3 times. 3 charged cycled before we test. 
4. Same room temperature
5. No SIM and NO WIFI connected
6. Running offline benchmark app and offline videos to see how long it depleted the battery.
7. Final step, when the phone power is drained empty. We monitor the USB adapter voltage check to see how many mAH this battery absorbed from the charger until 100% full.

Final Step - Charge Speed and Max capacity

We can know how fast it's charging and how much total mAh it holds when it stops charging.

The actual max capacity is important. What's the point of high capacity battery if it's lower mAh than the original max capacity?

At the same time, I'm typing this, another brand of high capacity battery company contacted me. They are willing to give me some of their products to compare.

So I might write more other brands review in the future.

17th Jan 2019 - 1st day
The battery is really better. Noticeable for about 15%.


20th Jan 2019 - 3rd day
The battery now should be in the best condition. But it's decreasing fast like the other so-called high capacity battery.
Now the whole performance it just lasts about 10%% longer time usage.

I need to extend the test a week more because the original battery doesn't decrease the max capacity so fast.

Decreasing it's capacity so fast. 84 mAH is gone.
From 2232 dropped to 2148 in 3 days. Charged 4 times.

One charged cycle should just minus around 1 mAh. Honestly saying that I'm not surprised or disappointed.
But still thanks to our battery sponsor.

26th Jan 2019 - A week after

The battery is good but the actual capacity dropped more again. This means the original battery decreases the maximum capacity slower than the high capacity battery after each cycle charged.

Test conclusion: 

It really extended the usage of time. But only expect for 10%. But the 10% extra would just last for 3 months and then it would be the same performance as the original.

If you keep changing the high capacity battery every 3 months, the performance is good.

Should we use the third party high capacity battery on the iPhone?

Yes if the price is cheaper than original.
Because it's strong in the first few months but weaker than the original after 6 months. 

Again saying, Apple is not stupid.

iPhone Battery Fast Drain Motherboard Problem | Power Run out fast

iPhone motherboard fast drain out battery problem?

• iPhone is leaking battery power quickly
• Consume or draining the battery fast even not using
• Replace a new battery but still draining fast
• Restored the firmware and still the same

If you have an iPhone that having drain or consumed battery power fast. The first thing we suspect is the battery, but what if the problem still exists after you replaced a new battery?

A lot of shops claim they know how to repair motherboard, they really don't do well. Most of them send to another shop to do or they just blindly change whatever IC that is related to power, after they messed a lot of things, then they return it with the same problem plus wasted few weeks of time.

Today I'm going to teach you the SOP of checking the iPhone logic board drain problem. (SOP = Standard of the procedure)

(I uploaded a Cantonese video into YouTube. English subtitle provided)  - YouTube Link

It's best you read the entire article instead of just watching the video above link. More details in this article.
Especially for those beginners who want to learn the repairing iPhone motherboard.

Tools require:

DC power supply 

iPhone power cable

How to check the iPhone logic board drain battery problem

1st diagnosis

Unplug everything, including the battery, LCD, and all flex that connected to the motherboard. Except for the power button flex which we need it later. (We still can click the power button without the flex, but not saying that in this tutorial)

The next step is to connect it to the Power Supply.
The power supply can read how much your iPhone is drawing the power.
Technically, it's called checking the "Current respond"

Set the Power Supply's current reading to 1A or lower.

We must turn the knob slowly. Slowly giving the power voltage into the iPhone.
By watching the meter of Amperage we can know the iPhone motherboard is draining the power before we power it on. 

Slowly raising the voltage until the battery level about 3.7v.

It should be staying in ZERO and NOT drawing any power before we switch the iPhone ON. 
This means the current reading is at 0A.

My power supply's left gauge is Amperage meter. We look at the lower line because I already locked it into 1A.
In this case, the red needle stoped at 0.02A (20mA).
This means the iPhone is leaking 20ma before we power it on.

This is an iPhone 5S that having a battery drain quick problem. Even if we switch the iPhone off, it will still drain out the battery power.

Can it be fixed?
Yes, but it's not in today's topic.

What if the scenario above is not happening? 
Yes, If so then go to the next step below.

If you sure the above is normal then we do the second step of the diagnosis - BOOT-UP TEST.

2nd Diagnosis: Boot-Up Test

What is boot-up test?

Boot-up-test is when we click the power button once and without holding it to turn on.
At that moment, the iPhone motherboard will do a self-loading test. 

This is very useful to the technician that wants to read the current response from the motherboard.

How to do the Boot-up test:

Connect the iPhone motherboard with the DC Power Supply.
Hit the Power Button once. Just click it once lightly. Do not hold the button to power on. We don't want it to be fully power on.

When we just lightly click once on the power button, a normal iPhone would load from 0 into 80mA and then drop back into 0.

If the iPhone has a charging IC problem, it can be easily detected by this method too. 

This is a digital power supply. The function is the same. But it can be more accurate compared to Analog Meter Power Supply. More advanced diagnosis methods will need it.

As you can see in the photo above, this iPhone booting-test is loading 218mA. It's very high compared to the normal iPhone. A normal iPhone is only loading 80mA in the boot-up test.
This indicates this iPhone logic board has a faulty circuit that drawing a lot of power. Confirmed it's a motherboard problem, so then we can scan it with a thermal camera to see which part getting hotter than usual. 

The below video is the thermal camera that we use to scan the motherboard problem.

Maximum of iPhone comsumption is 1A.  (1A= 1000mA)
But iPhone is never constantly loading 1A.

Only If CPU is doing a full speed benchmark test. 

 

So far there is no app that would causing the iPhone CPU running in full speed all the time. Only just a few seconds. 

 

By the way, this is an iPhone 7 that boot-up at 200ma.
This means it's already consuming 200mA when it's turned on.
I'm sure this iPhone 7 at least need to charge 3 times a day.

Can it be fixed?
Yes.
 If we are first hand to repair the motherboard, it will be a quick JOB which can be fixed within a day. 

What if the above two scenarios are not happening?

Then the problem is coming from one of the flex, LCD, or camera.
Connect all the flex back except the battery then do the methods above. Eventually, you'll found out it's the external problem which it's not a motherboard issue.
Then you're lucky. Because it's easy money. A Screw-drivers job that no need micro soldering.

We received countless failed repair iPhones from local shops. They messed up a lot of things which they shouldn't touch. They changed things without a proper diagnosis. Obviously, they have no training/educated.

The worst matter to me is their workmanship quality, they usually damaged the board further. In the end, we repaired it at a higher cost and a longer time to fix a simple original problem...

 Everyone can draw Mona Liza. But the problem is how good are they?
iPhone motherboard repair is the same as art.

How to check battery health and original?

Most users upgraded to latest iOS 11.3 or newer.
Inside come with new feature about battery health.

It's normal if it doesn't show maximum capacity after replaced battery (Even from Apple Center). But if it is saying needed to service, then you might having battery problem.

If health below 80% is consider very weak. Should replace it.

Charge twice a day is consider weak too.

However, today topic is "How to check battery true capacity and genuine"

The best way is to use PC program read the "real" capacity and how many charged cycle, genuine battery or fake.

It's called 3uTools 

In new iOS battery health check, you can only see battery health percentage. Surely it's NOT so details and accurate as PC program to check.

By using this 3uTools, we can even know is your battery been replaced before, and battery production date and Serial Number.

If you didn't use PC to read it, you never know the battery you replaced is new and genuine or not. 
If "they" put high grade battery, you never know with this iOS battery health check.

I highly recommend you to download 3uTools to read it.
It comes with a "Full diagnosis" that can even tell you the camera original, iPhone production date, refurbish unit and other more parts to verify it's genuine.

Photo above is the original battery that we replaced.
Since the new battery hasn't been fully charge, so it's 0 times cycle.
Health 100% (Health will become 99% if charged to full once)

As you can see. The battery current condition can hold 2865 mAh. Slightly higher than original design 2855 mAh. 

(It's normal since battery is made by chemical. So it would be + - 5% from factory designed.)

A high quality grade A battery usually between 2300-2600 only. 

Even you bought new iPhone, it might be just 99% health and capacity is slightly lower or higher 5%

Read here if you looking for higher capacity battery:
So far until now, those higher capacity batteries are scam. I have so many customers get cheated.

Higher capacity battery won't exist for Apple iPhone. Because Apple lab had spent so much money to design the iPhone with maximum battery performance. Who can beat their product? Unless that someone has special technology and they selling those to you at cheap price?
