FP5 - Battery Life

It was mentioned e.g. here

that AoD blocks deep sleep and so this IMHO means that it’s a problem with some process involved into AoD function.

Anyway, I think that more detailed analysis always helps… :slight_smile:

Agreed.
I’ve been accumulating figures for over a month but it’ll take a while to summarize and very busy right now. I certainly see no evidence for AoD itself causing excessive battery drain. The first few weeks in September the phone was using a lot of power no matter what I did, but a few days after installing FP5.TT3P.A.112.20231016 I’m getting much more reasonable results (sometimes as low as 1.1%/h in aeroplane mode, AoD enabled with flip-case closed, also using Kinscreen with proximity to turn on screen). I’m not suggesting the improvement is due to the software update. I rather suspect that the earlier draining may be related to the quantity of data stored on the device.

If others are seeing evidence for AoD preventing sleep, it may be in conjunction with some app or setting that I don’t have. Maybe we should run some tests in Safe Mode. I’ve already posted about the phone’s ability to turn off pixels.

I’d noticed that battery drain (and no deep sleep) caused by AoD on a factory reset FP5 without installing any app except AccuBattery…

This was sometimes a problem with older phones, but more recent models have optimized sensors that consume little power. Some of course, so using the proximity sensor to turn on the phone will necessarily have some cost, but negligible. It wasn’t a problem on FP2, FP3 or FP4 as far as I know.

Well we’ll just have to keep on looking! :wink:

Awesome, then at least it’s reproducible by others as well. That’s a relief. Because I hoped it would be solvable and this is. If it was a hardware issue it would really s#ck.

I think the battery drain during AOD is not caused by the process itself, but rather the display drain. Because I downloaded Productivity app (v 2.5.8) also known as Goodtime - Minimalist Pomodoro Timer (from F-droid) and it is capable of making it full screen productivity timer (basically like AOD just clock counting down minutes). The battery drain is the same as with FP5 AOD.

We’ve seen that the display may even be turned off by covering the proximity sensor and still the drain is higher than what it should be. From this we can conclude that it’s not the actual display hardware that burns energy. So the experiment with a different app probably just shows that the phone cannot sleep well if it has to count down minutes, either.

Maybe both made the same mistake and keep the device from deep sleep? :wink:

fair point :slight_smile: I just hope it will not take a year to fix this. AOD is such an important feature.

This line really struck me. With AOD correctly implemented on an AMOLED display, there should not be an overall backlight-like effect visible in AOD mode.

Independent from the questions if the percentages come from either the display, the AOD process, or the interplay between display, AOD process and whatever else, for me the primary question at this point is still: is the current AOD mode supporting an actual “only needed pixels active” way of working?

(disclaimer: this is my very first forum entry here, sorry in advance if my way of interacting is not in line with the expectations here. I did search for “backlight” within this thread, it only showed up once, so I hope my comment isn’t covered already somewhere above)

Cheers!

There is no such thing as an only “needed pixels active” mode. OLEDs basically have an individual light source per pixel. Instead of filtering out light from an white light (like normal LCDs work), to make dimmer images, the light source just produces less light. If you tell an OLED to show a black pixel, it will just not turn the light on.

So something is telling the OLED to not show a perfectly dark image and that something is very likely not the app, but rather a firmware issue.

Hi and welcome to the forum.

There’s a topic on this subject where you will find answers to your question. TL;DR: Yes, but please read the topic.

So I read a lot of these posts on this thread and looked at all your screenshots.
What is our verdict when it comes to the battery life of FP5. After all the updates has been done and AoD is off, is it as bad as for example this review says? The reviewer says he is gaming and stuff, but for non gamer user, how is it?

I’d say it’s not as bad as many reviews said, by a comfortable margin.

And what does the review say how bad it is?

Review mentions 16% of battery drop by 45 minutes of mixed usage (bit of gaming and web browsing).
It also says that battery drain is ok in standby.

It says 45 minutes of use caused a 16% drop in charge level.

And what would be the expectation or good? With what data are we comparing?

Without AoD and Gaming I see around 11%/h.

It seems the camera increases this and Apps like Maps for sure.

Overall I think its similar to the FP4.

I am struggling on some days with 80%, do you think there is a way to make it a feature request? Meaning, create an option for a user-defined limit. What would be the best way to approach this? Contacting support?
