Anybody else’s iphone dropping battery by like 4-5% at once?

[The Game 161]

My battery life is fine generally and I have 33% left with 17 hours total but I’ve noticed this morning I got out the car on 48% then suddenly it was at 41% from car to the office. Then I’ve noticed my phone was at 37% and now has dropped to 33% after it stayed on 41% for a good 30-40 mins on standby. Any reason why this would suddenly drop 4% just like that? Anybody else had this issue?

Happened to me a few times, but i think it's just a software glitch. Reboot and see if it continues.

My best experience after using iphones for 6 years is to do a clean restore without using local pc backup, but feel free to use icloud backups such notes, contacts and apps datas.
Hope this help you too.
