Yeah, it's a budget phone but hey... are 450$, that's a lot for me in my country (were a minimum salary it's less than 3$ a month... aka Venezuela), and it's a new phone! We aren't talking about a 65$ phone.
Anyways... the 1% drop health juts after the iOS14 looks "normal" and I wanna think it's a recalibration needed, I don't know... since I plug the phone when reach 20% at night. Just in one or two cases, the battery has drop from 15% in a call and I didn't notice just at the end of it.
Well, in any case, I share here how the iOS14 doesn't work in the same way. The best battery day I got was last Saturday. You can see always use 80% of the battery (charging at 20%) and then I install the iOS the Wednesday and PLOP, look at that!
An obvious hour less... even worst after 13.7. With it (13.7), I really felt the battery was good enough but now I'm in WhatsApp and I can see the 3-5% drop in less than 10 min. I'm always in 25% of brightness fixed. Since day one. By quarantine, I'm in home, I'm not outside so I turn off automatic brightness.
Ok, it's a budget phone again, but I'm not expecting a worst activity than my 4ys old Samsung J2 Prime. Even that battery I feel can do better.
How was doing ALL the people during the iPhone 6-8 era with that battery?
Look those image:
=80% iOS13.7 6:14hs
+80% iOS14.0 3:18hs
=80% iOS14.0 5:14hs (almost here give me two hours more, thanks the universe)...
The Monday-tuesday I was busy enough in the laptop, so I don't reach the phone quiet a lot, but Wednesday in the early morning I install the update, use lees that 50% (bussy again) and look at that.
