iPhone 6(S)/Plus iPhone 6s Battery Life

[Jerhen]

I went to an authorized Apple service provider last October and got a brand new battery replacement for my iPhone 6s. As of lately it seems like my battery life has been really crappy. I am on the latest version of iOS. Does anyone have any suggestions to improve battery life or has anyone also experienced bad battery life lately? See my battery usage below. Thanks.

The 6s battery life was just okay and was never a leader. However I'm wondering if it's the 3g connectivity that may be causing the issue. LTE is much more efficient in terms of battery life.

You might be right. Here is an updated image of my battery usage. I have been in the same building since my original post. Notice the 16 minutes of usage verses the percent of battery life consumed.

I'm afraid this is par for the course for A9 6s/SE iPhones, iOS 12 really kills the battery life. On my SE, on low power mode, I was only able to get about 2.5 hours of screen on time.

It's almost as if apple wants you to upgrade your phone with every OS update, hmm...

If your battery dropped 28% in 16 minutes, your battery/device is defective. It’s not just an iOS problem.

I have seen brand new iPhone SE’s last 2x+ my dad’s SE with a year old battery at 94%.

This is normal for a 6s on iOS 12. Looking at 10 day history, 100% battery depletion is around the 2 hour screen on-time mark even on a brand new battery (on WiFi 90% of the time)

My friend bought a brand new SE. It's on 12.2 I believe. Her screen on time is easily 3.5-5 hrs or so. I have personally verified it.

My mom has a 7 that got its battery replaced around 9 months ago, its on 99% and 150+ cycles and she too gets 3-5 hrs of screen on time each day, based on the cellular signal.

I'm pretty sure a brand new 6s will have a screen on time in excess of 3.5 hrs on average.
