FP5 - Battery Life

Don’t know if I have a different model, but my FP5 lasts for around 3-4 Days.
I would take a screenshot, but this graph looks kind of “weird”

Here is a normal looking graph…

The batterylife is superb for me. Easy 2-3 days.

You’re not using your phone ;p

@G33K2303 do you turn off the network most of the time? And only turn it on when you want to search something?

I’m asking because that’s what I used to do before (years ago) to keep my battery from running out; just in recent years I’ve learned to just charge every night and keep the network on all the time. Which tends to be more than sufficient (I end up at night with between 55 and 35% of battery left).

Your screenshot is a good reminder that it is possible to have really good battery life if you’re willing to turn off your network connection.

Most of the day I keep mobile data turned off since I have wifi. During 6-7 hours sleep, I have the airplane mode on.
I have switched off 5G and turned down wifi scanning. Had the same on the FP4, but the FP5 is rocking that battery stat for whatever reason.

That is how it looks for me.

  • Battery saver is always on
  • Always on Display: disabled
  • Very light use

If I actually use my phone for more than occasionally looking something up and texting, I need to charge it daily. The Battery life is about comparable to my old phone (Oneplus 5T running lineageOS) with its original 6 year old battery. So I also think that it should last way longer. But it might also be a report problem. When I used the phone with ~5% battery left, the charge level didn’t change for a very long time.

See my 1st post in this thread… I had pretty good battery usage even without airplane mode or other tricks.

Unfortunately on subsequent charges the battery life has always been worse. Not massively so, but I know it could be better, I just don’t know how ;_;

For comparison, here’s my second cycle from 100% to 20-something. At first glance it seems similar to the 1st cycle (charged 4 days ago and 1 day plus some hours remaining), but the screen time, mobile network, and app usage are far less so it should last longer; also the 1st screenshot shows clearly less steep discharge curve between moments of usage.

I’m using the /e/-OS prerelease on my Fairphone 5, and a regular day ends with more than 50% in my battery. Regular setting for everything, no AoD, and mobile data disconnects during WiFi, which is most time of the day for me. I’m mostly using basic applications like web browsing or Matrix chat (Schildichat), but the JavaScript-Based Matrix chat with hundreds of rooms is pretty heavy on the CPU, maxing out the CPU during sync. Maximum brightness with dark / true black theme wherever possible.

What is your screen on time though? And do you start your day at 100% or 80% charge?

I start with 100%, screen time I can’t tell because that feature doesn’t
work yet in the /e/-OS prerelease I use.

@Dryhte: What is AoD?

Always On Display, this display that shows some information (time, notifications etc.) all the time.

A very desirable feature if it weren’t for the battery drain

I have made the same experiences as many others here, which is really frustrating. Without touching the FP5, it loses 6% within an hour (AOD on)! My wife’s Pixel 7A, with more or less the same setup (AOD on), loses 2% - the FP5 thus consumes 3 times as much. If I disable AOD, it’s still consuming 4% an hour. I had the FP4 before and wanted to change to FP5 regarding the AOD feature and the better camera, but now I’m really thinking about to sell the FP5 as it’s important for me to leave the house without having a powerbank with me.

Please do contactsupport and share these screenshots with them. I agree that the standby drain isn’t normal, also with AoD enabled. I hope it’s not because of their irregular SoC. I hope they can solve it in software.

Hmm, after updating the OS (FP5.TT3L.A.106.20230918), my discharge curve got gentler, similar to how it was after the first charge. I wonder if it’ll get steeper again… it would be nice to have the proper tools and know-how for debugging battery usage.

I’m not sure why there’s a gap.

Just a stupid question, are you restarting your phone from time to time?
I’ve had it happen to me multiple times, that my phone just kept using more and more battery until I restarted it.

For me the biggest surprise with FP5 was the lack of notification LED. Although this seems to be the norm these days, but my all my previous phones have had the led, so this was difficult to accept. I ended up using AOD and configuring it with the AMOLED AOD app to act like notification LED would. So that the screen stays black until I get a notification and returns black when notification is seen. Configured that way, it seems that AOD spends like 1-2% of battery per hour, which is acceptable.

No LED on FP5 O.o? I’m very surprised. Especially since it must consume far less battery power than the screen. It’s an astonishing choice…

Not again. the same useless discussion was going on two years ago, when the FP4 was released. Some people seam to love the notification LED ,others don’t. In most current phones it doesn’t exist anymore. So deal with it or don’t buy a Fairphone.
