I don’t want to repeat myself, but I’m truly amazed at how, not only the phone itself is so efficient, but the modem itself.
I thought the Qualcomm x57 was a modification of an old 5G modem such as the x55. And I don’t know if it is (if anyone has technical information about this modem please share it, there’s a lot of secrecy around this custom made modem), but my God it is very efficient!!!
For context: I’m on the countryside, far from the city, far from my home WiFi, and usually, using just data on non urban locations (where the coverage is worse) drained the battery a lot. This was the case with my 2016 iPhone SE, and my iPhone 8 (with an Intel modem). The phone would get hot, the 4G/LTE coverage was poor on some spots, and the battery drained way way faster.
Now, I’m on the same town/village, on the countryside, and… I just can’t believe it! First of all, I have 5G coverage everywhere! No drops, maybe lower signal strength on some spots (two bars or even just one), but the iPhone SE 3 never gets hot. Well, it gets a bit hotter with some clunky website or badly encoded 1080p YouTube video, but it is rare.
I charged this phone nearly 40h ago, I’ve spent two nights listening to podcasts with the phone locked, and all the day of yesterday, and I’m still at 12%. It is true that I’m using low power mode since yesterday evening, I enabled it at 35%, but still, it amazes me especially because I’m only using 5G.
I had Automatic 5G until a few days ago, when I switched from Automatic 5G to 5G Enabled, making it use just the 5G network. And maybe the 700MHz band (with better indoors penetration) is providing me this better coverage even inside the house, but wow, this is amazing.
I never, ever imagined that a 5G smartphone would be more efficient than a 4G/LTE one.
I don’t care too much if this Qualcomm X57 is a derivative from an old 2020 X55 modem, although I admit I’m really curious, but the efficiency is really amazing.
