FP5 - Battery Life

It’s explained in the menu itself :nerd_face: An iPhone (12) has indeed a better battery life, better than most Android phones.

The AOD app, it’s this one https://play.google.com/store/apps/details?id=com.tomer.alwayson

Sorry about the mess. As a newbie here, the post editing tools feel a bit confusing to me.


thanks, I’ll give it a shot

The idle drain definitely can be low. My phone was charged to 80% 93 hours ago – that’s almost 4 days ago. And now it is at 43%, showing 4 days remaining.

Problem is nobody here seems to have a clue how to debug it when there’s higher than anticipated drain.


Thats without AoD enabled?

And the App AccuBattery gives a good overview

I have several Google Stuff deactivated, I expect its better with Custom ROM

I can only agree. I am quite interested in buying a Fairphone 5 (FP virgin) but the battery capacity/drainage is making me think twice.

My ideal phone would keep alive at least 48 hrs idle without charge.

Idle for 48h shouldn’t be a big challenge. I think my FP5 would be able to do this:

And this is with updating train information over and over again to see which challenges Deutsche Bahn wants to present to us next, listening to music, a bit of surfing…

According to accu battery

Just AoD should be off at the moment, its draining quickly when enabled


Can you share more detailed stats? For me this is impossible to achieve. I don’t game on my phone, no AoD (which is really disappointing) And I get around of 4-6 hours of screentime and then I am left with about 30% at the end of the day. When I don’t charge it overnight and have battery safer on from 35% onwards it wouldn’t last much longer on the next day. I wonder how you use your phone. The only thing I can imagine is that you give it short charge boosts, but keep it below 90% so that the battery stats don’t reset.

Mee too,
I have my FP5 since 3 days. I think with optimization it is possible.

Seriously I am reassured of usage.

I noticed, that once I activated the Always on Display (AoD) the phone is not entering deep sleep anymore.

I did not use any AoD apps, but the stock Android “Always show Date and Info”.
With AccuBattery I get ~3,6%/h (Display off, wake), with 141 mA and 0m in Deep Sleep.

I suppose that’s one of the major issues for having such a high battery drian with Always on Display. Can anyone confirm this behavior?


I’ve also noticed that on FP5 with AoD on.



Hi y’all,
I got my fp5 and instantly noticed extended battery drain. I turned off “double tap to wake”, “5G” and “AOD” and its fine now. I already rulled out the first. I will eventually rule out either 5G or AOD we will see, but I think it was the AOD.
Just fyi…

The 5G is definitely not the big drain (unless, maybe, there’s a very bad but still existent 5G signal where you are).


It has been repeatedly mentioned that -for the sake of battery life - it is better to charge it only till 80% and not leave it uncharged below the certain threshold, I guess 20%.

While I am trying to do this, sometimes the battery does not keep up the whole day. What would then be smarter - a. Recharging during the day, b. Charging till 90 or even 100 but not letting it go below 20%, c. Charging upto 80 percent but going down till even 5 percent?

Thanks for any suggestions

A is the best choice, then C, then B.


I dont let a battery dictate my life… I try to not charge over night to 100% (i.e. dont let the phone plugged for hours after its fully charged) and not let it go down to zero, else I dont care that much. I think battery and charging techniques are smarter nowadays and should handle charging in a way that I dont neee to care too much.


CalyxOS introduced Charging Control in one of the last releases.

Not sure if they took it over from another ROM. :man_shrugging:

Just enabled it. Apart from that, re-charging over the day.

yes, I am using this setting in stock rom on FP5, that is in my opinion a great addition. But there is no option to set the limit - only 80% or none.

I’d prefer a 90% limit, more chance I’d get to the evening with about 20% left. As it is, I just charge overnight to 100%.
