For context, this is a very much used Samsung Galaxy S20 FE.
I highly doubt that it’s going to last 16 days under any circumstances, battery saving mode or not.
Since taking the picture 5-10 minutes ago, it’s decreased by 2% and 8 hours and asked me to update it twice 😄
I got a Pixel 3a (released in 2018) back in early 2022. It was “used” but like new. I put CalyxOS on it, which probably helped improve battery life, but I use my phone so little that, at the height of my phone use, it lasted 3-4 days. When reddit killed third-party apps and I couldn’t use RiF any more, battery life went up to 5-7 days. My most-used app is the clock because I use the stop watch to time my breaks at the gym. Nowadays, it’s more around 3-5 days because the battery is slowly losing capacity, but that’s still pretty good compared to what I hear from other people who use their phone all day.
used to use a used pixel 3a with a pretty thrashed battery, custom roms did help a bit. now i’m using a heavily debloated and modded android flip phone, i can go a whole week without even thinking about charging it (used to last like 2-3 days in it’s stock config)
Yeah, not using your phone a whole lot + degoogling it adds a lot of battery life. And an Android flip phone sounds cool. Can you do modern phone stuff with it, at least to some degree? Like 2FA for banking, emails, stuff like that.
to an extent, it depends on how well-made its rom is. mine has a pretty crappy one where it tries its best to gaslight you into thinking it doesn’t run aosp, so the only way you can install/update apks is through adb or shizuku (f-droid and aurora didn’t work with permission denied errors). also, this phone doesn’t have touchscreen, and very few mainstream android apps support keypad navigation. to make matters worse, its rom is missing some library for virtual cursors to work correctly, so for those problematic apps you have to use either a bluetooth mouse or scrcpy. i was eventually able to hunt down apps on f-droid that handle keypad for all my needs, the only one that doesn’t work is steam guard, still need a mouse for that one. for maps i found a 2011 gmaps apk that still works flawlessly today. was able to install it since there were no google services bundled with the thing (they prevent downgrading google’s apps), so all i debloated was removing some t-mobile crap using canta. some modern android apps also have terrible dpi recognition (phone has a 240x320 screen which is PERFECT for j2me emulation), so you need system ui tuner to set the font size to something absurdly low like 0.025 to initially set up the app so it’s buttons fit on screen. usually once the app is set up you can reset the font to a usable “small” value.
this is where i ramble a bit off topic
before 2g got shaky in my area, i went through 3 nokia phones in a summer, the n95, e7, and n8. they were fully usable for me, and imo android pales in comparison to symbian with the amount of customization and user respect it had. like sure, it was slow at times, but it treated me like a capable intelligent adult, sometting android hasn’t done since 4.4. before the nokias, i used a pixel 3a with /e/os, which was fine, but android feels like it keeps getting worse with every update nowadays. i wanna make a mobile linux distro with a ui like symbian, but it’s too much work.
i feel i’m getting off topic, sorry for my rambliness
TL;DR: don’t buy a sonim xp3plus, there are far better android flippies out there
