Not great. With suspend enabled and if I don't use it much, about 8 hours to 0%. If I leave it on (i.e. disable suspend), about 3 hours.

I'm honestly almost always near a charger, which I also realize is just a cope.

This is not normal for this phone. I think you should ask for help on the forums or by email. Examples:

You're probably right, and battery life varies a bit day-to-day. I haven't done a formal test to double check my statements above, more just a feeling.

I've had the phone for a while and the battery has gone through many cycles. It has definitely lost some capacity.

When you say suspend, what does that look like in terms of receiving a phone call or SMS?

It's still experimental. It works for some users [0], but not for others [1,2].

Recent progress: https://social.librem.one/@dos/110180625035442292.

Those forum posts are from more than a year ago, a lot has improved since.

The modem asserts a wake pin when you receive an SMS or phone call, causing the SoC to wake up. Services that rely on data (IM, e-mail etc.) don't wake the phone up (they will rely on periodic wakeups in the future, but there's no infrastructure for it yet).

An update that makes communication with the modem after resuming from system suspend reliable has been deployed today (previously it would often fully reenumerate and cause various troubles in the process, now it's instant).

OMG I got this update and modem resume has been flawless since!!!

Thanks for your hard work to get this fixed!
