Battery drains very quickly - 48h (version 1.7) to 8h (version 1.8)

• /e/ version: 1.8
• Device model(s): Fairphone 3
• Device rooted: yes

Summary

I just installed the 1.8 version on my FP3 yesterday at the morning. At 4PM, my battery runs out of power. Nothing change between 1.7 and 1.8 from my end, in term of behaviour (I do not use my phone so much when working)

The problem

Discharging very quickly the battery.

Normally, in 1.7, I had 48 hours of battery in average.

Install the version and wait 8-10 hours depending of the phone.

Definitely, it is not a behaviour expected when we install update on a phone, for sure.

Solutions

Workaround A friend of me had the same behaviour 1 week ago when he installed the 1.8 version, he performs a reset of the battery by discharging totally it (during 2 days, he's perform on/off actions to consume at the end the battery), and recharging it. Since that, it seems OK.
