Okay so as said in my last thread on batteries, the ZTHY brand drained far to fast.

And now I find myself fretting over what battery to get instead, too worried it might turn out the same and I'll of spent the money for nothing.

So I ask all of you, is there a replacement battery you all know of that's a good choice?

Oh, and would an OEM battery be a good choice? I see them all over ebay.

OEM battery should be no problem but why you need to change battery ?
This model and others have similar problem of quick discharge or battery capacity fluctuation but the source is the battery connectors, not the battery itself.

This happened once before with the battery it came with, the one I have in now is a NewPower99.
But the charge is lasting less and less, yesterday it drained in 2 hours. And it's starting to overheat a lot.

If your tablet pops up message which says the tablet is overheating, this is a sign of cracked battery connector. Most of the issues of overheating,
quick discharge from this tablet can be solved easily by re solder the battery connector. Lithium battery can last at least one to two years depending
on how you use your tablet. I had some dead batteries discarded by others, but just a little fix: adjust the clip of battery cables closer so they can make
good contact with battery connector's pins, they come back alive and work normally.
Change new battery and you still see the same problem, the problem is not from battery.
I see many people throw away a working battery and don't know it just has a loose connection.

Is there anything in depth that can show me how to fix these problems?

Read and look at these pictures, you might understand why Samsung tablets have a common problem of quick discharge or battery problem.
Samsung has many flaws in designs , the Galaxy Note 7 phone's explosion is an example

Battery problems are very common in many Samsung tablets, you have to look carefully to see if the battery is actually bad.
Most of the time, the problem is not from battery. It has its certain life time and cannot fail quickly.

Yikes. Sadly I have no way to do any of that. And I don't know anyone who could either. Only thing I can do is get a new battery. It would be a complete waste of money, but I literally wouldn't be able to do any of that. It's all just to small and I don't own a microscope.

I bought an used Tab Pro 12.2 so I believe it may be at least one year old. Resoldered the battery connector and adjusted the battery cables's terminal,
it has been more than a year and I don't have any issue of battery. I have more than 10 of used batteries and have no chance to use them.
The tablet is in a sleep mode more than a week, when turning on it still keeps the charge with a little less. This tablet can last 2 to 3 years without problem if
both battery connectors fixed properly.

I want to do it. I just can't.

I mean, I saw one post where someone had opened the white piece so you could see inside. I can't figure out how to do that. If I could I might actually be able to fix it, but.

Welp, I tried on my old battery, and broke the pins trying to cut away the plastic so I could actually reach the pins.
You don't need to cut the plastic cover of battery connector. The battery cable clip can adjust from the top with a thin knife


This connector tends to loose over time, Samsung fix this issue by using silver conductive glue or solder cables directly to the connector on mainboard ( done when sending to repair ).
However, the main issue is from the connector on mainboard, this one needs to be re soldered.
A complete repair should fix both connectors, like this one : resolder the battery connector on mainboard and solder the cables directly to the connector on mainboard.
As I already said, the cables no need to solder to mainboard as average users have no way to replace a bad battery

Okay can you please tell me how you were able to view it so upclose like that?

This thing is just so tiny I can't see things good enough to even risk using the knife.

I tried a microscope app on my phone but everything was just one big blur.

This USB digital microscope is good to view and take picture, but you cannot do work with this microscope due to small distance between
the lens and the object. Bring it far away, the image becomes blurry.

In order to do something under microscope, it must have at least 6 inches clearance between the lens and object like this one
