đŸ‡«đŸ‡· 🇬🇧 ProblĂšme de batterie / Battery problem during the night

:fr: Bonjour, j’ai un souci avec la batterie de mon FP3. Elle se dĂ©charge mystĂ©rieusement pendant la nuit
 :first_quarter_moon_with_face::battery:Il est dĂ©connectĂ© du wifi ou de la 4G mais rien n’y fait, je me lĂšve le matin et ai perdu 10 a 25% de charge sans rien faire! Le seul moyen d’endiguer le problĂšme est de mettre en mode avion mais cette solution ne me convient gĂšre
 Des idĂ©es? Des problĂšmes similaires ?:grin:

 during the night, my batterie lose 10 at 25% for nothing! I’m disconected about wifi or 4G and it doesn’t work better. I don’t understand the problem
 Please! Help me

Just use “flightmode” during the night and observe if there’s any difference.

Was Bluetooth enabled?

:uk: Hi. Can you look into “Battery Settings” to see what’s consuming so much power? To do that, go to battery settings, click on the 3 dots on the top-right corner and click “battery usage”. You’ll now see what app is consuming. If it’s not an app, you can once again click on the dots on the top-right corner to switch to hardware consumption.

Maybe you’ll find some information on those two screens. You can maybe post a screenshot here in order for us to check? :wink:

:fr: Salut :slight_smile: Vous pouvez vĂ©rifier ce qui consomme de la batterie depuis les paramĂštres Android. Pour cela, allez dans les paramĂštres de la batterie et cliquez sur les trois petits points en haut Ă  droite de l’écran puis sĂ©lectionnez “Utilisation de la batterie”. Vous pourrez voir les applis qui consomment de l’énergie. Si ce n’est pas une appli, cliquez Ă  nouveau sur les 3 petits points pour passer sur l’écran de consommation du matĂ©riel.

En espĂ©rant que ces deux Ă©crans vous donneront quelques infos. Peut-ĂȘtre pourriez-vous poster une capture d’écran ici pour que l’on vĂ©rifie ?

Hey ! I’ve tried ans it works but I prefer found an other solution :slight_smile:

Bonjour, merci pour votre proposition ! J’ai regardĂ©, rien n’y fait
 Tout est optimisĂ© et aucune appli ne tourne en arriĂšre plan visiblement :disappointed_relieved:

@Sarabi

Putting apps to sleep if not in use (not just close the gui) can help.
There are apps doing this automatically (e.g. Greenify), but more recent Android versions (Nougat+) should do a pretty good job on this already, not necessarily needing such third party apps.

On my FP2 with Marshmallow the MXPlayer app keeps hammering my firewall wanting to access the internet. But putting it to sleep (force stop, not just select quit in the menu) prevents it to drain my battery over night.

Bonjour,
J’ai parfois le mĂȘme problĂšme de chute de la batterie en veille, avec une perte de plus de 5% par heure sans utiliser le tĂ©lĂ©phone. Ce problĂšme n’est pas systĂ©matique, et j’ai peu de mal Ă  trouver la cause. Il n’y a aucune appli ou processus en cause dans les paramĂštres de la batterie, les % manquant n’apparaissent mĂȘme pas, comme si rien ne les avait utilisĂ©.
Il me semble que le problÚme arrive souvent aprÚs avoir chargé mon téléphone trop longtemps, toute la nuit, mais je vois pas trop le lien!
Est ce que ce problĂšme t’arrive toute les nuits ou est ce plus alĂ©atoire? DĂšs l’achat ?
Je continue mes tests pour trouver le facteur declenchant, et je te tiens au courant si je trouve!
Bonne soirée.
BĂ©a

Merci pour ce retour ! Oui ça me le fait systĂ©matiquement la nuit, depuis que je l’ai effectivement. Je fais vraiment attention Ă  ne pas le charger trop et pour rien, quand je le met en charge c’est vraiment qu’il est Ă  moins de 5%.
Je ne comprends vraiment pas !

Do you keep your phones in airplane mode over the night?
Standby mode not necessarily mean the phone strictly is going into sleep mode.
Often auto-updates are being made over the air in night hours too maybe draining the battery or even put an updated app in an undefined state until the phone is restarted.

Hello,

I have a similar issue.
I didn’t notice it during the first months. It started about 2 months ago. Sometimes (not every day), my battery is discharging very quickly.

What I have noticed until now:

  • in “normal conditions”, the battery can lasts about 50-60 hours. Wifi enable during day, airplane mode during night, no big use of data or application.
  • sometimes, the battery discharges very quickly. It can happen during the day or night. In these times, the back of the phone seems hotter than normal.
  • when I notice the battery is discharging too quickly, I reboot my phone and the problem solves.

I guess there is some sort of application or task running in the background which consume the energyn (thus the issue solved by a reboot??). I can’t remember any new application downloaded at the time the issue appeared. I don’t remember any system upgrade at this time either.

I will try to check the battery setting and monitor if any app is involved in this and will keep you informed.
In the meantime, if anyone has some solution, I’m keen to have them!

Perhaps you could try, if your phone is rooted, to observe the output of the top command as superuser in a terminal (Termux is good). It shows the processes using the CPU, and it could show you if something is draining you battery by using the CPU. Otherwise, you can also download Better Battery Stats, it does it as well I think and more easily, although I’m not sure about it (but again your phone has to be rooted).

If you don’t understand, or it seems too complicated for you, and you don’t feel to do it, don’t do it and forget about it (if needed I can give further explanations but I’m not really a specialist).

:fr:
Peut-ĂȘtre vous pouvez essayer, si votre tĂ©lĂ©phone est rootĂ©, de regarder le rĂ©sultat de la commande top en tant que superutilisateur dans un terminal (Termux est bien). Cela montre les processus qui utilise le processeur, et cela pourrait permettre d’identifier si quelque chose draine votre batterie en utilisant le processeur. Sinon vous pouvez aussi utiliser Better Battery Stats, cela le fait aussi et plus facilement, bien que je n’en sois pas totalement sĂ»r (mais encore une fois votre tĂ©lĂ©phone doit ĂȘtre rootĂ©).

Si vous ne comprenez pas, ou si ça vous semble trop compliqué et vous ne le sentez pas, ne le faites pas et oubliez ça (je peux éventuellement fournir des explications un peu plus détaillées mais je ne suis pas vraiment un specialiste).

:uk:
Perfect example last night:

  • Phone was charged during the evenning until 11pm (100% charge)
  • During the night, it was in airplane mode
  • @7am, battery was at 57%. Battery stats showing only 3% usage.

@Alex.A : my phone is not rooted. I may try to do it, but I’m not a specialist either, so i’d like to explore other solutions first, if possible :smile:

It’s very difficult to see what uses your battery. So a battery drain can come from different things. I had a problem like this and it was the motherboard the problem (Process irq/288-wcd9xxx draining battery), but for others it can be the battery, a module or even the software. And rooting your phone would allow you to have a little idea of what drains your battery so much. So except if it’s something very simple, very few methods will be efficient to find out. And nearly all of them (if not all) imply rooting your phone.
But indeed, if you don’t feel like doing it, it’s probably better not to do it, because rooting can cause problems if you’re not careful.

I experience exactly the same issues that SimonL. I’m not an expert so it could be dangerous to proceed to rooting. Can someone at Fairphone provide solution to resolve these repeated issues ? Many thanks in advance

They may be able, but maybe not. And if they don’t know, they’ll probably want you to send them your Fairphone for repair (which finally may be the best solution).
