Standby battery time
I've seen a few people around here struggling with battery life, so I thought I'd share my experiences.
[I'm getting fantastic performance](https://i.imgur.com/REPqHNr.png). (The "2 days ago" full charge is rounded down, it's somewhere between 50 and 54 hours.) That comes to, conservatively, 6h screen on time PLUS 72h standby; I don't think you could ask for more from 2 Ah.
Android has a ridiculously wide slew of battery options at this point. I am a tinkerer and have spent a shitload of time going through them. I have reproduced my settings for you below.
The major sacrifice I make is the relatively high-effort toggling / adjustment of airplane mode, data, wifi, location, bluetooth and screen brightness as necessary. If you have no interest in touching those toggles you will not see numbers like 6 + 72, but you might still benefit from the other settings. My area also has really poor 4G so I stick to 3G. Maybe the 4G antenna's a battery monster?
My usage patterns are: one or two calls a day, 80%+ of time spent at houses or coffee shops with good WiFi, Maps / Uber around once every two days, and SOT is mostly messaging apps and browsing simple websites in Firefox.
**Set and forget**
* Unihertz Appblocker: On (complete restrictions for Chrome, Play Music, YouTube, Uber)
* (Per-app) Background restriction: None
* (Per-app) Battery optimisation: All except WhatsApp, Phone, Messages
* Accounts > Automatically sync data: On
* OK Google hotword detection: On
* Battery Saver: On (from 100%)
* Intelligent power saving standby: On
* Battery Manager (detect draining apps): On (doesn't actually affect battery life I assume?)
* Preferred network (2G, 3G, 4G): Match to best locally available with strong signal (to avoid energy wasted searching and swapping) - mine's on 3G
* Apps installed: Relatively few, but monsters like Uber, Whatsapp, Riot, Spotify, Uber, and the full Google suite are present
**High effort**
* Data: turn off when you have wifi
* Wifi: turn off when not available
* Location: turn off when not using Maps, Uber, etc
* Bluetooth: turn off when not in use
* Aeroplane mode: enable overnight
* Screen brightness: 40% indoors, otherwise 80%
* Timeout: I keep the timeout long but remember to turn off the screen after use
If anyone has questions or perspectives, shout. I get ridiculous nerdy glee from battery maximization and the puzzling-out thereof.
