Same android phone , same apps but one drains battery faster.

As the title say, I have 2 android phones , both factory reset and logged in with google accounts. Checked the dns logs on both-

Phone 1 connects to google server but is minimal

Phone 2 is going bonkers, connecting to google server , xtracloud server etc.

Phone 2 battery drops 5% in a hour and phone 1 doesnt drain at all.

Which bring me to the conclusion that phone battery draining has something to do with google accounts as phone 1 google account has fake name and details but other has real name and also a phone number linked to that account.

Please feel free to correct me. Thanks
