How can I verify is a cell phone battery capacity is truly 3000mAh?

[GoodEnough]

Is there a tester? Can the phone display this?
Like to verify if the cell phone battery I bought is actually 3000mAh ?

 

[GoodEnough]

Ok, I installed CPU-Z on my phone.

How does it get the 3000mAh?
Is it hard coded into the battery,
or is there an actual electrical measurement taken?

Why not just run youtube for 10 hrs and compare to reference discharge times

Hook a load to it that drains it at exactly 1 mA per hour. See if it lasts for 3000 hours.

It's the only way to be sure.

What if he drains it at 500mA? Should it last 6 hours?

If so, and I'm anticipating his question here, which app does that?

it's rather easy.

1) take battery out.

On the battery is a code. that code tells you. IF you want to test it put it in the microwave for 1minute.

I did that. Now it smells funny. What am I looking for? I'm using a monocle and a magnifying glass but I don't see anything but slightly warped plastic?

I know how to measure its drain, but not sure on it's capacity.

What do you think it means? :biggrin:

If has the OEM label its fine if not its probably less.
Keep in mind if the battery is for an old phone its life won't be as good as the first battery because batteries are all made when the phone is being made. Batteries you buy years later have been sitting on a shelf somewhere for years.

Your battery is good enough irregardless of it's capacity or it's complete disregard for Ohm's law which clearly states that irregardless is vregardless. Regardless of what anyone else thinks.

Ah then you've made one of the classic blunders of not realizing the true answer was already given within a joke answer.

Useless thread.

Enjoy trolling each other.

Label showing that it's 3000 mAh is Good Enough for me. :biggrin:

Tell me if you find out... My laptop has a habit of overestimating the battery by an hour and a half. No wonder it went completely dead after I shelved it for a few weeks with supposedly 75% charge left.

attach positive terminal to penis and negative terminal to balls.

if it hurts when getting a boner, then it's good enough.

 

[John Connor]

LOL!

The way to spot fakes a few years ago was to make sure the math for the Wh matched to the mAh and voltage specs. You'd find the right voltage and Wh specs, but the mAh would be overstated since that's all they thought to change when they slapped the new sticker on.

I'm sure they've learned of their idiocy by now, but I thought I'd share.
