Question Honor Magic 8 lite battery quality

[jaston]

Hi all. I'm new to the forum so please be kind.

TLDR:

2 brand new separate handsets:
Advertised capacity 7500mAh
Accubattery reports: 6800mAh ish

It's possible I'm doing something wrong here but here goes....

(I've removed smart charging, safe charging, smart battery capacity and have set charge limit to 100% to get a fair measurement)

I took delivery of my Honor Magic 8 lite from Vodafone last week... I started suspecting the battery capacity wasn't up to scratch almost instantly. I installed Accubattery and as suspect the health was measured at 88% after a few full charge cycles.

Vodafone have a battery health tool bundled with the phone which also confirmed an issue (battery drain test fail). Vodafone and all the staff were excellent and they actually swapped the phone for a new one immediately in store.

Now i have the replacement handset.... (2 days old) Same issue again! Accubattery reports 91% health and Vodafone's battery tool reports battery failure.

Has anyone else experienced this?

Am i doing something wrong?

Welcome to AC!

Was the replacement device refurbished?

Welcome to Android Central! Considering that the phone was released earlier this month, I'm guessing these aren't refurbs. Even if they were used, it'd be unusual to degrade a battery to that degree in this short time frame.

Battery health estimates might take several charge cycles to give an accurate result, so I'd wait a few more regular charge cycles before coming to any conclusions.

Thanks for the replies. Yes, both are brand new. I'm prepared to give it a few more charge cycles to confirm (I did however do this with the first one). I'll speak with the Vodafone store staff today and see if they have had any similar issues.

I'm also thinking that perhaps accubattery and the Vodafone battery tools might not be tailored perfectly to silicon-carbon batteries?

Interesting point -- I'm not sure if the silicon-carbon thing would be an issue. Maybe send an email to the Accubattery developers and ask them? support@accubatteryapp.com

AccuBattery often underestimates capacity on new phones, especially with silicon-carbon cells and fast charging. It needs many full charge/discharge cycles to calibrate, and initial SoC (state-of-charge) tables can be inaccurate.

You bring up a very excellent point and may be the case.
