I seem to have more relevant data.

2018-08-29, 12:52 PM

Phone was fully charged to 100%. It's running Oreo. We initiated factory reset. After a few minutes it was done and the battery now said it was at 36%. Initialized the phone with the google account. Did NOT install any apps. Left it unplugged for a few hours and came back to find it still at 36%. Mindboggling. Left it unplugged overnight. This morning STILL at 36%.  Mind you, this is the phone that RIGHT after the Oreo update would seemingly consume its battery in 3 hours or less although NO app was shown as consuming a lot in the battery apps usage section. The phone would also randomly reboot once battery got under 50%. To reiterate, NONE of these symptoms occured until AFTER the Oreo upgrade.

 

Obviously, the battery is not the issue here. It's how the phone reporting battery level to the OS that is the problem. The phone is erroneously reporting 36% battery level to the OS for 12 hours now. Not sure why this is not escalated to engineering. Moto is probably replacing a bunch of phones that are not defective in the hardware but probably have a software bug introduced during the Android upgrade process.

 

Please, I need to know what to do with this phone.

Update: 12 hours later, phone is still at 36%. Accubattery says it used an average of -152mA/h with screen off. with screen on, -408 mA/h.

Hello! I have same probler after installing OREO. But in CPU-Z I see huge load on all 8 cores of CPU. Resolve it by disable "Google Duo" application. Now, battery dry not stopped, but became less and phone not off when I try to call )))

Hi Mag555,

 

Thanks for reporting. I wouldn't say for sure that this is caused by the update. I can check the battery performance of your device if you allow me. Could you please update your profile with current phone, carrier and serial number -- this will help me investigate. Please make sure that the options under Settings > Motorola Privacy are on as well, and let me know (just reply here) if it's okay for me to look at your apps to see if they are a source of problems.

Need help updating your profile? See here

 

Best regards,
Rich

Re: Android 8.0 is killing my phone

2018-09-09, 9:07 AM

I did the factory reset, choosing new installation, wipe all data. Starting out fresh was a pain, so far I've only downloaded a few apps from the Play Store and (fingers crossed) no bad battery drain. Also found out that unplugging the charger when it reaches 100% is not correct, it needs to charge longer. I also restart my phone after charging.

I sent mine for replacement as it was still under warranty

2018-09-09, 14:26 PM

As there seems to be no answer to this problem I did not want to wait any longer to see if Moto can figure out the issue so I sent the phone back for replacement. Interestingly, after performing the 'calibration' 3-4 times in a row the phone would NOT go above 48% charge upon restart. Accubattery reported that the battery had 4% capacity left. I think the OS upgrade fundamentally messes up with the battery reporting from hardware to OS. This was after a full factory reset. This is my final post on this unless the new phone exhibits similar issues. I am not going to upgrade the new phone to Oreo BTW.
