I've been running wild across the interwebs looking for info about undervolting a Jolla phone. Unfortunately I haven't found evidence that somebody has actually pulled it off. Is it even possible at the moment and would it have any substantial gains? I haven't voltage tweaked a smartphone before so I thought I'd ask if you guys have a clue. Cheers!

The main reason why I'm asking this is the battery drain which gets pretty nasty even when I'm not dabbling with the phone that much.

Have you tried narrowing the battery drain down?

Battery life is one of the main things I've found advantageous about my Jolla (vs. various Android devices). I can normally keep it alive for 2 - 3 days without charging.

Second Mike here, your battery drain is not coming from bad CPU settings, you'd rather want the governor be set to performance once the screen is turned on and set back to $default when display gets dimmed again.

Wow I can keep mine alive for 24h tops if I 'm lucky. It's funny because I don't run any cpu intensive apps apart from random web browsing which shouldn't be that taxing either I guess. I usually got whatsapp running throughout the day and randomly read books using Aldiko. Those are basically the only android apps running. I even tried factory reset to no avail. Could it be the battery slowly dying then?

I run down to 41% with: 4h music-playback, the occasional browsing, always on email on 2 accounts, ~1-2h android games and a couple of calls (20-30min), writing sms, taking some pictures and reading SNs from them at work (that was about my day till now), currently 6 apps as cover, wlan always on (imap idle). So if I cut down on the android gaming and the music just a bit I could have a phone at ~50% the next morning. If I cut gaming and music I get about 3 days. So you better find out what your battery drain is coming from...
