Itās not bad. But my Pixel 3 has a ~2900mAh battery with a battery health of 75% after 3 years. The Pixel doesnāt last that long compared to the FP4 which has 1/4th extra battery capacity. But when it had 100% capacity it came close. So in other words it could still improve software-wise. Or maybe itās because it has an LCD screen.
This is mine ā¦
SOT: ~2h
Pretty much comparable to @AlphaElwedritschās battery statistics but I was quite conservative with degoogling to avoid anything breaking:
pm uninstall -k --user 0 com.google.android.gm
pm uninstall -k --user 0 com.android.chrome
pm uninstall -k --user 0 com.google.android.calendar
pm uninstall -k --user 0 com.google.android.apps.docs
pm uninstall -k --user 0 com.google.android.keep
pm uninstall -k --user 0 com.google.android.apps.tachyon
pm uninstall -k --user 0 com.google.android.youtube
pm uninstall -k --user 0 com.google.android.apps.youtube.music
pm uninstall -k --user 0 com.google.android.videos
pm uninstall -k --user 0 com.google.android.setupwizard
pm uninstall -k --user 0 com.google.android.setupwizard.overlay
pm uninstall -k --user 0 com.google.android.googlequicksearchbox
Besides that, I deactivated the play store and the default messaging app.
Although I donāt use a Google account, I still run on the default launcher. I may change that in the future but havenāt seen the need yet. What do you think? Any room for improvement?
That looks pretty good as well. Though I understand just as FairphoneHulk, youāre not a heavy user, 2h SOT over 2 days is veryā¦ low usage
However, it does show very low consumption while idle.
My device is draining 4% overnight. I did not disable bluetooth, I think Iāll give it a try and see if it ends up improving idle battery consumption.
Thatās definitely right
I usually switch to airplane mode over night. And yeah, the battery drains awfully fast with more SOT. LED displays are just not known for being top energy savers.
I was able to replace most of Mapsā functionality with OsmAnd~ and NUNAV Navigation. While I use OsmAnd~ exclusively for hiking and biking, NUNAV is really good at car navigation.
Once again a little optimized.Based on the tutorial from @rar0 and @Stanzi
Gave a boost again.
Residual charge: 37%
SoT: 7hours, 47 minutes
Can not complain
Hi all,
Iāve just bought a new Fairphone 4 and I have some questions regarding battery usage. Iām using stock OS (Android 11), and relatively few apps (Firefox, LinkedIn, Whatsapp, few banking apps).
Battery drain seems to be very inconsistent: I typically leave my phone on overnight, but with airplane mode on, and with wifi/mobile data disabled. The first night, my phone battery only drained 1%, which is compatible with my experience with my previous phone (a Samsung a5 - 2017).
However, starting from the second night, the phone is draining ~15% battery with same setup.
I have tried to use AccuBattery, but without much success. That said, the power consumption of the phone seems to be relatively high even when idling. Right now AccuBattery reports around 250mA draw, and 20%/h consumption with screen on, 4.5% with screen off. These numbers seem very very high.
When browsing internet I can see the battery percentage dropping very quickly (e.g. 1% every 3-4 minute or so). On my old phone (which was 4 yrs old) I could get with same apps (and Android 8, which was the reason of the upgrade) 2-3 days out of the (small) battery. With the FP4 Iām nowhere near that.
The only āsuspiciousā thing Iāve done was to install (and then uninstall) an application to enable ātap to wakeā (as I was a bit worried about power button wear just to see notifications). Since the app was not working as I expected I have uninstalled it. So Iām wondering if itās possible for the app to have altered some of the phone factory settings, and now, despite the app is uninstalled, Iām stuck with bad settings.
Any ideas? What is your normal power draw? Iām surprised Iām having issues with this as many reviews mentioned that battery life was ābetter than averageā. Thanks!
Hi and welcome to the community. I moved your post to this existing one, giving some impressions. Using the FP3 not FP4 I can confirm that a tap/wink to wake app def drains more battery, I think that the Phone is never really in ādeep sleepā due to that. Therefore I deactivated this again on the FP3 .
Note that I have uninstalled that app. So, Iām not sure how that could still be the culprit, unless it permanently changed some settings in my phone. AccuBattery reports that 80% of the screen-off time phone is in ādeep sleepā, so that should be ok (but then again, Iām not sure why the power draw is so high in deep sleep).
Hi and welcome to the forum
I have n FP3 and get between 1 and 2% over 16hours when in aeroplane mode.
Do you have any data you cannot retrieve as you could do a factory reset or maybe as you only installed 1 app and removed it you could try starting in safe mode.
Finding the culprit piecemeal can take some time.
Aeroplane mode should disable WiFi, Network, Bluetooth and NFC
Iām sure I have a few apps that try to connect during the ānightā but as they fail they use limited power, etc.
Yeah - thatās really whatās bothering me - losing 15% overnight with everything turned off is, I think my main concern here. Iāve tried safe mode - but then itās hard to make a comparison, given I cannot use AccuBattery in safe mode. I will maybe look into factory reset (I donāt think resetting app data would be enough to undo whatever was done).
I have tried safe mode, what really changes. It itās only not using AccuBattery, ??? Can you start it in safe mode before you rest for the night and the phone is in aeroplane mode and just see what the inbuilt battery check says?
What I meant is that I would have liked to make a power draw comparison using AccuBattery between safe mode and non-safe mode, but thatās not possible, of course.
Using safe mode overnight seems like a good idea. The built-in battery stat doesnāt seem to report anything unusual, even now, so I donāt think that will provide insights.
Yes was overdoing the āinbuiltā I really meant the recorded drop overnight
could it be that your phone is still setting itself up? usually it can take several days for a new phone to āstabiliseā and then power consumption settles at a much lower level (same happens after software updates).
It could be - that said, Iāve just seen another review which I didnāt see before which mentions some issues with battery life:
https://marketresearchtelecast.com/ct-3003-the-fairphone-4-in-the-long-term-test/207392/
(I think the above just contains a (translated) transcription of the video).
Specifically:
āThe battery life is below average. In the test, the Fairphone 4 switched off after 9.8 hours of watching YouTube via WiFi, other smartphones almost doubled. With the Fairphone 4, I usually got through the day on one battery charge, but barely.ā
I think this is more or less on par with what Iām seeing here. Just for fun, I resurrected my old Samsung phone (note itās not a flagship by any means, just a midranger with a 3000mAh battery) - and it does draw a lot less power: on idle itās sitting at 70mA, while the fairphone is sits around 200mA (even though the screen on the Samsung looks a bit brighter, but thatās probably due to the AMOLED).
I guess itās probably something that I could live with - although charging the phone once a day instead of 2-3 times a week doesnāt feel like a great upgrade (considering itās replacing a 4.5 years old phone). Of course itās always possible that the phone is not working as it should, because of some issue with my specific phone, or some app going rogue (although I canāt see anything strange).
I know you might not want to go that way butā¦ maybe root your device so you can install BetterBatteryStats and get really detailled battery usage ?
Otherwise I think itās possible the ātape 2 wakeā app have changed the battery statistics and messed up the power consumption but it usually comes back to normal after a few days of consistant usage.
Have you got the device for a long time ? And did you debloat it ?
In my experience the device tends to āadjustā after a few days/weeks and battery life increases. Though I debloated everything I could and use apps such as Servicely and Naptime.
I only charge my phone every 2 days and use it normally.
Thanks for the suggestions. No, would not want to go down the root path
Also I did not ādebloatā it, because, compared to my previous samsung, this already feels debloated enough . If you refer to remove some of the google services, I use them quite a bit.
Iāll wait few extra days to see what happens, but this is looking not great. For instance, the official android battery usage stats reports 5% battery gone with 16 minutes of moderate browsing. Honestly it seems like itās just the wifi - this phone is much, much faster at loading websites than my previous one (probably 10 times faster), but it comes with a hefty price in terms of battery life.
At the end of the day I will have to see if the limitations of the phone (mediocre battery life, absence of a proper way to see notifications when off, so and so camera performance) are ok for me to put up with. I understand that for people that feel more adventurous, there are other paths possible - but I sadly donāt much time to tinker between work and family. Since I donāt change phones much (last one lasted 4.5 years) I mostly want something no fuss, that ājust worksā - and this is starting to look like it isnāt it 100% there (which would be a pity because I like the idea behind the phone, and the great community it has!).
Well could be, I had trouble understanding why my fp4 was draining 1-2% per hour during night time when it could take 2 or 3h during day time to drain this 1% (in idle mode of coure). Until I realized my bedroom being upstairs, wifi signal was much much lower and inconsistant, which constantly forces the phone to try get better signal hence use more battery.
But yeah 5% in 16min thereās something fishy right here.
Thought of that too - but at night I leave my phone in airplane mode (and Iāve also disabled bluetooth and wifi scanning). So that shouldnāt be an issue? This morning Google Photos popped up in the battery stats, so I assume it must be running overnight to do who knows what (I do not have syncing of pictures - the microSD is my cloud ).
