Itās not clear to me what happen when I open an app (say maps, or camera) and then go back to main screen. Does the application stay active? I assume it does because I can force it to stop in the settings menu.
So does an app use energy if it stays opened? Is there a clean way to quit an app?
What apps do you have sideloaded? I usually find that this has something to do with that. The more apps which require constant connection & refreshing the quicker the battery drains.
I have sideloaded Aroura store, and signal, I am stopping both manually after use and putting the Kompakt into offline mode over night this seems to have given me a slight improvement, but having an messaging app turned off seems to defeat the object slightly

Signal should not be the issue at all. I have both Signal & WhatsApp downloaded & use them regularly (without manually quitting) and my battery life is 5-6 days.
Hmmm. I wondering if itās the Aurora Store somehow, but I donāt think so. Do you have an launcher installed?
No the launcher is stock, I have the Aroura store stopped & havenāt used it for several days.

Iām curious, if any other users with Aurora installed have decent batter life (around 5 days)? Can you guys comment?
sorry I missed the question about having a browser installed, I dont have any browser on the Kompakt.
I also have bluetooth and wifi off, my signal at home is a consistent 2 out of 4 bars, my signal at work is 4 as I am 200 yards from a phone mast

@sundancermartin I will ask our team about this, because Iām about stumped as to what could be causing this.
Hey everyone!
I wanted to share some notes from my past few weeks of testing Kompakt ā maybe theyāll help someone save a bit of battery (and nerves).
When I first switched to Kompakt, I was way too optimistic. āNo Google Services, no tracking junk ā finally, a phone that just works and lasts forever!ā Wellā¦ reality turned out to be a little more complicated. 
Messengers ā the biggest battery drain
Without Google Services, messengers like Signal or WhatsApp keep an open connection all the time ā unless you force-stop them. Thatās why your battery disappears even when youāre not using the phone.
Signal can be used with a third-party push service, but itās buggy. Eventually, I discovered that iMessage actually works really well on Kompakt! Since my family already used it, it became my main messenger again. Itās smooth and surprisingly efficient.
WhatsApp, on the other hand, kills the battery in no time ā just donāt.
In a perfect minimalist world, weād all go back to SMS, butā¦ well, weāre not in that world 
Radio modules: the quiet killers
This part surprised me the most.
Constant Bluetooth connection (smartwatch, earbuds, etc.) drains the most power, then GSM, and finally Wi-Fi ā which is actually the most gentle.
So, if you turn off Wi-Fi and Bluetooth, rarely use GPS, and switch GSM to 2G, you can get 10ā12 days of battery life easily ā a few SMS, 3ā5 minutes of calls, and around 30ā50 minutes of offline music.
Hi-Res music? Nope.
The chipset is old and not happy with heavy Hi-Res audio. When I tried playing my lossless library, I could see the battery dropping.
I re-encoded everything to AAC 256 kbps ā and that solved it completely.
Background apps donāt really āsleepā
Even built-in ones. DuraSpeed helps a bit, but I often just go old-school and manually stop everything that tries to wake up.
Two ways to live with Kompakt
1. āAll-in-oneā setup:
My first idea was to make it my all-purpose device ā NewPipe for podcasts, OpenBubbles for iMessage, Kindle for reading, Garmin Connect for my watch.
Result? About 2 days of battery after all the tweaking. Basically the same as my iPhone ā but with more effort.
2. āBack to basicsā setup:
This is where Kompakt really shines.
I use it almost stock: no custom launcher, no messengers, no streaming. NewPipe only to download, then listen offline. No Garmin sync.
Yes, Apple Music and Paradise do work here, but streaming eats too much power. I just listen offline ā via cable (thank goodness for the headphone jack!).
Sound quality is okay, not hi-fi, but decent.
Oh, and I even switched to 2G ā LTE isnāt really needed, turns out 
In this setup, I get 10ā14 days easily: 1ā5 SMS, short calls, a bit of reading, and up to 2 hours of music or podcasts.
These days Iām somewhere between those two modes ā using Kompakt as my main phone, but planning to move the āmedia lifeā to another device (probably an iPad Mini).
Then Kompakt will stay what itās meant to be: a calm, distraction-free phone that just feels right.
Thanks for reading ā and if youāve found any other battery-saving tricks, Iād love to hear them!

Thank you for your analysis of battery life. Battery life is important to me. After installing the Signal app, my battery lasts a maximum of four days. Iāll try some of your tips.

I thought I would post an update on battery life after our exchange.
I charged the Kompakt to 80%, since then I have had it running with Wifi and bluetooth off, signal messaging app running without manually shutting it down, still on stock launcher. no other apps sideloaded, with the exception of Auora store which has its services manually closed down.
I have had 3 phone calls and sent and received 23 text messages and 6 signal messages, used the note taking app for approx 10 min, and shared as a hot spot for 5 min. the red battery light came on this evening with a reported 8% remaining. which equates to a shade over 40hrs of standby / use share.
I am really liking the Kompakt as a handset, but Im quite disappointed with the battery life Im getting

What if you had it charged to 100%, just to double-check?
I couldnāt get mine to work long unless I force shut Signal/WhatsApp, but also charging limited to 80% eats up a visible fraction of battery run time. I might have to revise my previous statement from this thread, some are telling me that slower battery level drop around 100-90% might be a matter of presenting, just like Google inflates signal strength indicator: Android inflates your phone's signal strength, but for good reason - Android Authority
Offline+ overnight also helped me extend the battery life a bit when I was testing.

Thatās what I did with my Punkt MP02.
Was quite a perfect combo. On a normal day (going to work or so) the Punkt is smaller and lighter than quite any other and for other case, when navigation, cameraā¦ could be needed I took the iPad mini and with me. Only problem was on motorcycle ride, iPad was to big to take with so I had no camera.

Absolutely. This short period with Mudita made me realize that the role of a smartphone in my life was somewhat overrated. In eight cases out of ten, all I really need from a device is voice communication with my family. One time out of ten it is a bit of music or books, and in the remaining case I can always just wait and do everything on my Mac. It is wonderful not to be constantly online ā it turns out the planet does not stop because of that

@sundancermartin, I agree. I, too, really enjoy using the MK, but Iām getting an average of 2-3 days of use. Memory is fallible, but I do wonder if this is related to the later OS updates. I havenāt changed the apps/setup on my phone since before the last OS update, but I seem to have lost a day of use somehow. I used to get 3-4 days.

I am using mine from early May.
I charge up to 80% and use the battery to approximate 20% before the next recharge cycle.
Excluding inkOS, the only other sideloaded App that I use Viber.
If I do heavy texting during the day, I average 1-2 days before I drain down to 20ish percent.
If I force stop Viber and use it relatively rare, I get 2-3 days. I still use SMS a lot for texting with my wife.
If I am at home (letās say during the weekend) and I rarely use my phone, use the Offline+ key and force stop everything, I can squeeze around 5 day, maybe moreā¦ depends on the occasional 5 min phone call I might receiveā¦
Pretty much works for meā¦ my iPhone used to die before noon after an overnight chargeā¦

About average: I started to use my MK 16 or 18 of July.
My battery info say Ā« 16 times fully loaded Ā» so that means around once per week. Canāt complain.

I have charged the mudita to 100% 4 days ago the battery is currently at 36% I figure I have 2 to 3 days of battery left.
I am manually closing signal after checking and responding to messages (3 to 4 times a day) and I am activating offline mode overnight. Im really pleased with the battery performance now.
I plan on testing the same setting with signal left on all day next, although it does flash up a message every now and then saying the app is not optimized for use without google play services

further update ā¦
I have managed to get 5 days from a charge of 100% this evening my battery Is at 21%, Im averaging 12% per day, so I think 6 days is possible, I think that is very impressive.
Tuning on the offline feature seems to really help, and the energy saving eink screen also appears to be a factor, both reasons I bought the Mudita coupled with a privacy orientated os.
Hats off to the design and development team, for producing a great piece of thechnology.
