Battery Health on new phone only 91%

Mueslis — Mon, 25 May 2020 13:47:58 GMT

Good day,

I bought a new Samsung Note 9 and it is supposed to have 4000mah battery. Using the app accubattery it consistently shows me a battery health of 91-91% since the beginning! Is this normal? I cannot get it over that value. Because I paid for a new phone but appartently I got an old battery? May I return this phone now? I have been charging always 20%-80% and have it recorded, so I treated the battery according to all scientific standard practices.

Thank you in advance.

No app can establish real phone capacity.

It is an estimation and accuracy is not high. You can still request a verification in a samsung center but if i were you i would just ingore accubattery estimated percentage if battery life is good.

Sure it might not be high but other users report that they have 95 or even 97%. Can you explain that to me?

And how does Samsung do the measurement then? Because I need a measurement which is objective and non biased.

They still cannot get a perfect measurement.

Batteries also degrade from being at ambient temp and degrade less but still degrade at 0 C.

That is the explanation. If you go for a replacement you may get a more degraded battery

Thank you for you answer.

I am actually very interested in technology so I know that they degrade and how to treat them. Where I live it doesnt reach 0 degrees and we are just now starting the summer so I don't think 5 months of moderate battery usage (I dont do games) would hurt it so much.

Yep. I meant that if the phone has been conserved at ambient temp for the 1 or 2 years before you bought it a lower than new battery capacity is to be expected.

Hopefully the end of the development of graphene will change all of this!
