Sure, that would stretch the battery time to maybe 2 days. But I still would have to have both of those in my pocket. Now I get 4-5 days on my smaller pocket ph

  > But I would still have to have both of those in my pocket. At the height of the Pokemon Go craze, people were carrying large batteries around in their backpacks, with a long wire snaked out of the backpack between the zippers to the phone in their pocket. Not the most practical thing, but it worked. It's kind of funny; the next season after that, many backpack manufacturers re-introduced the flapped-seal cable pass-through port that had previously gone out of fashion (it used to be a thing for people who were feeding their headphones into their bag to listen to music from their walkman or discman — not pocketable devices, for most definitions of "pocket.") But by the time the backpack makers did this, the craze was already over. While we're talking alternatives, another alternative is to activate your smartphone's "Battery Saver mode" permanently, and then disable things like Wi-fi (so it isn't searching for a signal when you're out and about); Bluetooth (I assume, if you're okay with the Nokia, you aren't a Bluetooth headphone enthusiast); and — if you really want to go all-out, and "people phoning you" isn't generally a thing — find an app that will automatically disable the cellular radio whenever the phone's locked/asleep. (Which would wreak havoc on battery life if you woke your phone up all the time, but is great if you only wake it up a few times per hour at most.) I've been able to pull a good few days of battery life from some rather old phones this way.
