I've been using my iPhone 14 Plus for about a year and a few months now, and I've noticed that regardless of my usage, the battery life seems to be draining significantly. For instance, social media apps like Instagram, Reddit, and Twitter consume about 15-20% of the battery per hour of screen-on time, while browsing using either Safari or Firefox takes about 10-15%. When the phone is in sleep mode, it loses around 5-7% battery each night.
With my regular 80-20 charge cycle, I'm only getting around 4-5 hours of screen-on time, plus another 2 hours with the screen off. I bought the Plus specifically for its larger battery, and while the performance was great in the first year, it seems to have deteriorated quite a bit since then. Could this mean I've just gotten a bad battery?

It doesn't sound too unusual. You didn't mention the condition of your phone though. Is it in good shape or has it seen better days? Also, are you using a case that might trap heat? Plus, the cellular signal quality matters too. If you’re often on 4G with weak signal, that can really drain the battery fast. Make sure to provide all the info for better suggestions!
Was your iPhone 14 Plus brand new when you purchased it? I'm surprised you chose it over newer models like the iPhone 15. But since you mentioned cellular data usage, that could definitely be impacting your battery life.
Yes, it was new. I got it during the iPhone 15 launch; the pricing was decent for a brand new 14 Plus 256GB. I didn’t have enough time to wait for the iPhone 16, so I figured this was a good deal.
I can relate to your struggles! I usually rely on cellular data too because the Wi-Fi in my home is pretty slow and I don’t get good reception at certain spots around campus either.

Oh, I see; my iPhone was new when I got it, and I use a rubber case. Does heat from the case affect the battery? My cellular connection is mostly 4G, but it varies between 1-4 bars depending on where I am. I couldn't share the battery usage details because I was trying to update my phone and it failed, so I had to restore it.
