High Capacity iPhone Battery Baseus - Review

Today topic is episode 2 of "High Capacity battery" review.
This one some of you might heard the name.

iPhone high capacity battery review
Baseus iPhone 7 battery 

Baseus iphone high capacity battery replacement
I'm going to install it in an iPhone 7.
The size of battery is totally same as original. It makes me wonder again. 

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

  • Restore the iPhone and latest iOS 12.1.2. No any third party app installed. Clean. 
  • Empty the power and charged back. 3 Cycled.
  • Run multiple test in the same temperature room. 
  • Final step, USB adapter voltage check to see how many mAH this battery absorbed from charger at 1% into 100% full.
  • No SIM and NO connect to WIFI.
  • Running offline benchmark app and offline videos to see how it goes down in 3 hours.
  • Of course the iPhone must be in very good condition. No issue and fully original parts. No repair before, except battery changing.

As usual, i'll use PC app to read it.
This company of battery really did their job to program the chip for capacity reading.
Let's see is it true as the system show us. Unlike the "previous battery" review which don't even show more actual capacity than design capacity.

Actual capacity is important. What's the point of high capacity battery doesn't show more mAh than the original 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 product to run the test. 

So there will be one more brand to test.

Result will be post here after two days (Now is 17-1-2019)

1st day, the battery is really better. Noticeable. about 15%.

3rd day, 20th Jan 2019. The battery now should be at the best condition. But it's decreasing as the other so called high capacity battery. Now in every test it just last about 10%% longer. I need to extend to test to one week.
Original doesn't decrease capacity so fast.
Decreasing it's capacity so fast. 84 mAH is gone. 

To be fair, one charged cycle should just minus around 1 mAh. Honestly to tell you, i'm not surprised but disappointed. Thanks the battery sponsor, they are willing to wait for more test result.

Update for 26th Jan:
Battery is good but actual capacity dropped more again. Original battery decrease actual capacity slower than this third party battery after each cycle charged.

Conclusion: It is really extended usage of time. But only 10% around. And the 10% extra would just last for 2 months and it would be the same or might lower than original.

iPhone High Capacity Battery, Last 20% longer - Review

Countless times i told the customer there is no such of high capacity battery.

A customer came in to replace an iPhone 6 Battery. He replaced it with a so-called higher capacity than the original battery that should be last 20% longer from one of Apple Repair Specialist.
But he still thinks it's battery problem which his iPhone 6 drain too fast. Need charge twice a day. However, it's not the battery issue which we already repaired his motherboard problem.

As you can see, it's written 2100 mAH.
 iPhone 6 Original Battery design capacity is 1810 mAH.
Apple is really provided best battery for its own product. They already maxed out the capacity and space that allow the battery to fit in.
Apple product is not cheap, you know?

The only way to find out its condition is NOT in iOS health or Battery Life app.
We must use PC program to read it!

Use pc to see battery report.  The photo below is using iTool (Chinese version). This program also allows us to transfer photo, backup data, set ringtone and songs without using stupid iTunes.
There is an English version too. Name is 3uTools. Download link

We found out his battery only have 1781 mAH after 139 charged cycle.
If it's high capacity which is 2100mAh, it would still stay 2100mAh after 139 charged.

This photo is our original battery which tested in the same way. It's 150 charged cycle and it still has 1802mAh. 
It's normal that battery is little more or less from 1750mAh, but 5% + or -.

Conclusion: Most of the high capacity batteries are a scam... 

Update: Someone is selling this brand of battery contacted me, he said it's unfair to read this because of charge cycled condition. So i put up another photo of another original battery reading which conducted the same test and charged cycled.
