Battery drain after replacement

Hi there,

The factory battery of my Pixel 6 (not pro or other, the 6) was getting bad, not lasting all the day anymore.

I purchased a new one and proceeded to replacement. But since then, it is worse than before (with a battery which is supposed to be brand new).

Of course we first think the battery is a bad one (cool, i lost money ! ) but, i wonder if that could be a software problem.

isn't that possible the new battery is not setted up properly, or the phone system cannot calculate the battery capacity well ?

i noticed something interesting : my phone is slow (not very much but enough to be spotted) when fully charged. The display animations are lagging, typing text is worse than usual, not precise, not always understanding which key i press etc. When the battery is close to 0%, everything is back to normal. The phone is much faster, precise etc.

this is what makes me think it is a software problem.

i want to be sure what exactly the problem is, before buying a new battery.

Any clue could help me

thank you !

Hi @gowbow,

Does this also happen when using the phone in safe mode?

Hello. unfortunately, it does. The battery keeps dropping very fast, like from 37% to 33% in only a minute, even though i'm doing nothing, with phone setted in safe mode.

Did you calibrate the new battery as shown in the ifixit Google Pixel 6 Battery - Genuine parts description?

If you did, can you try using the old battery again?

I realize that it wasn't that good but I assume that it didn't discharge as quickly as the new one. If it still behaves the same way as before then it's looking like the replacement is the problem.

Who did you purchase the replacement battery from? Looking at the battery I linked above, ifixit gives a 1 year guarantee on their battery so if you go to purchase a new one, check the seller's guarantee or warranty first before purchasing it. That way if the battery is the problem you shouldn't lose out, money wise

Hey ! sorry for taking so long to answer. i've been very busy recently.

i used the calibration tool as you told me. However, after following all steps, and the tool is ready to load settings on the phone, i get an error message, telling that the tool version is older than the android version. It tells that i can install a proper version. So that's what i did. But after this, the problem is still the same.

i don't understand. I am stuck because of this

@gowbow

Not sure I understand what you mean.

What tool did you use?

The calibrate instructions in the parts list I linked state:

"For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%"
