Need app to disable APN/save battery

I really like the idea of disabling the phone's APNs when it's just sitting idle to save battery. Unfortunately I've not found an app that can do this reliably.
I first tried Juice Defender/Ultimate Juice which is so configurable that I thought I'd hit a winner. It's (supposed) ability to automatically enable the APN for a short period every so often seemed like the perfect balance of powersaving/data syncing.
Unfortunately it didn't work out this way and messed up my APNs and internet access completely, even after uninstalling (until after a few reboots).
I tried Sleepy Battery just today. Again, the app didn't work as promised - it didn't re-enable the APN after the phone woke up, leaving me with no internet. Again, this app had made a change to my APN that I had to go back in and correct, after I had uninstalled it.
Has anyone got any advice, or can recommend an app that actually works for this use?

I personally use use APNdroid, it allows to switch 3g on and off and has a widget with it. It doesn't automatically turn the 3g on or off depending on your use, that's something you'd have to do yourself...
Hope that helps!

Try sleepy battery, juice defender, or another app I think it's called sweet dreams.

Thats really strange, I've had great results from JuiceDefender/UltimateJuice. It turns APNs off when in standby and turns them on for 15 seconds every 5mins to allow everything to sync. Really can't fault it.
I'd maybe suggest giving it another go? I believe there's an update coming soon from the developer to sort out some issues with the Desire. This might solve your issue.
Not come across any other app's that do what JuiceDefender does as well as it does.

I really wanted to like Juice Defender. Hopefully the update will help, so I'll wait a while for that.
In the meantime I'll give APNDroid and Sweet Dreams a try. Thanks guys

I would recommend getting the juicedefender and ultimatejuice is well worth the purchase! juiceplotter is also a great free add on. They will save you on battery and will automatically control your apn and wifi.

Just a quick question on JuiceDefender actually. I just bought UltimateJuice to try, love all the options it gives you. But, my question is this...
I have my apps (Facebook and the likes) set to sync once every 2 hours. I also have UltimateJuice set up to turn APN on once every 2 hours to allow syncing. Will these two points in time automatically sync up with each other? I can just see Facebook trying to update at 14:00, 16:00, 18:00 etc while UltimateJuice turns APN on at 15:00, 17:00, 19:00 etc.
Hopefully not though. Anybody know? Thanks.

I have wondered this, I if you've only got APN turning on every 2 hours you might as well set Facebook to sync every 2-3minutes because, my guess is that it won't attempt to sync if there is no data connection.

Hmm, possibly. I've set Juice to turn data on once an hour. I'll leave it like that for tomorrow and see how it goes. It currently claims to be extending my batter life by 1.88x, and if that remains consistent and it actually can do that then I'll be very impressed.

I've now tried APNDroid and I have to admit it seems like it does save some juice. But I forget to turn it off/enable my APNs frequently, and therefore don't get my data coming through for long periods. I need an automatic app.
Sweets Dreams does not fit the usage I want the app for.
So have gone back and tried Juice Defender again for today, and it seems to be working ok this time round. However it reports that it's multiplied my battery life by 1.95, but that is a complete load of rubbish. My phone was unplugged literally 12hrs ago, and I'm now down to 14% battery.
My use of the phone isn't excessive - searched the Market for maybe 5-10min, installed 3 apps, and uninstalled about 4 apps. Browsed internet for maybe 15min total. Sent and received 12 text messages each way. A few emails have come in that I've dealt with. No gaming action at all, no calls, wifi is completely disabled, I had just a couple of widgets updating infrequently (every few hrs) but I got rid of them early this evening.
What do I have to do to get some sort of half-decent battery life out of this thing?

sometimes u want to have data syncs when the phone sleeps, for example twitter if you have new mentions. I used quick settings (http://www.appbrain.com/app/com.bwx.bequick)
long press on the search button brings this up so you can change it quick.
You could change the sync frequencies to longer gap inbetween updates to improve battery life. I turn on my APN the entire day and I still get about avg 14hrs of usage

I use Data on Demand from the market. It's simples! Just turns data off when the phone is asleep. Doubles the battery life!

I like it! simples indeed!

I use juice defender/ultimate. It works incredibly well and I can now easily get 2 days use. I have a rooted Desire with MCRr3.
Without this software I stuggled to get 1 day.

After my first couple of days with UltimateJuice I must say I'm pretty impressed. Syncing seems to work fine with the schedule I have set up. I have it turning APS off at night, having it on when I have the screen turned on, and off when the screen is off and then turning back on to sync everything once an hour. Greatly improved battery life so far.

High battery drain

Im trying to find out what is draining the battery on my EVO EVEN WHEN THE PHONE IS WITH THE SCREEN OFF and SUPPOSED to be in STAND BY MODE (using the power button on the phone). I have SETCPU installed to LOWER the CPU to 245/384 when the screen is off.. HOWEVER THE BATTERY SEEMS TO DRAIN .
This afternoon I charged he batter till the green light came on. Made one phone call for 10 minutes and then later another one for 10 minutes.. I do have GPS and BLUETOOTH ALWAYS turned on since I use them all the time WHEN the phone is on for various APPS and my bluetooth earpiece and car adaptor... After those 2 calls the phone is down to almost 70% from 100%...
I have SYSTEM PANEL and also JUICEPOLTTER, SPARE PARTS and MINIFREEMANAGER installed and the programs are set according to what I have been reading on here...
SPARE PARTS tells me the phone has be MORE THAN ONE DAY with sleeping and the most used app is ANDROID SYSTEM. I look at SYSTEMPANEL and UNDER MONITOR HISTORY I can see that even when there is NO DEVICE USAGE, I still have around 15-30% CPU Usage (is this normal?). I also have it set to get email etc automatically.. some every 2 hours and some software every 4-6 hours.
What could be causing the battery drain? What is the best program to use to see the cause?
Im also not 100% sure SETCPU is using the screen off profile.. HOW an I tell this??? Any help would be appeciated...

Have you tried turning GPS off? If it's not actually being used, it won't drain the battery much or at all. However, if you're actually using it, it will.
If you're using navigation, that's a big battery killer, as it does constant GPS + a large amount of data transfer.
One thing you can try is to open Spare Parts, then go to Battery History and choose "Partial wake usage" in the top box. Things with partial wake locks are generally the biggest idle battery users.

I also just Installed a BRIGHTNESS WIDGET and turned off auto-brightness. the widget I am using has 8 brightness settings and double click for auto. I am using currently on the second brightness setting on the widget (it shows little ticks). I am told lowering the brightness from auto will help...

I read in another forum that there was a bug in the Facebook application that was causing the application to refresh its information several times an hour instead of once in a while at specific times.It would use power and bandwith when the phone is even in sleep mode with screen off. They also mentioned that there was a fix already issued for this. I cannot find the link any more to source it for you where I read this.

My stock EVO runs for days with the radios turned off until I need them.
Sometimes, if it ain't broke ...

My evo has been draining fast without all that on and well it's annoying. The only compensation I have is owning 3 batteries.

I haven't seen that Facebook issue. One other thing. In spare parts I have activity management set to aggressive. Could that effect battery life or does that help battery life. I also notice in spare parts that I See programs that I don't use ruining that I didn't see before.

From your list I can only see two things I would kill these programs and wait and see what happens.
WUNDEREADIO
FACEBOOK
Everything else must run. For me Slacker radio kept my EVO on all day long eventhough I was not using it. The new version seems to fix that issue. I am guessing your problem is WUNDEREADIO. I would reboot (resets your battery information) kill Wundereadio. Then go to Settings, About, Battery and monitor your Awake Time vs Up Time. Write down the numbers. Turn off your phone and wait 10 minutes. You should see a gap in time. If so then it is Wundereadio.
Good luck

I think slacker and wunderradio were in the list because I just used them.. wunderradio inst in the list today.. BUT SLACKER is but not in the partial wake.. its in background ...
I changed my backlight setting from auto to using a widget that has 8 brightness settings and it is on the 3rd setting.. I dont know what the AUTO backlight was setting the screen at...
I also adjusted the MINIFREEMANAGER according to some settings I found online..
also I have SPARE PARTS set to AGGRESSIVE... would that have anything to do with it??

Check systempanel first thing when you wake up, but go into monitor, then history, and switch plot to top apps. It will tell you exactly whats been using the battery/cpu when there's been no usage.
As you know, the bt sucks a lot of battery, if you really do use it often, with a bunch of apps, you may want to consider tasker, which can be set up to turn bt on only when your on a call, or using certain apps.
Sent from my blah blah blah blah

Will tasker turn on bluetooth when a call comes in? IE will it let the bluetooth earpiece ring so I can answer it from the bluetooth earpiece?? also can I set tasker so that when get in my car, it will KNOW I am in range of a bluetooth speakerphone and it will turn on BT and connect??
I leave BT on all the time for these reasons....

Looks like tasker wont do anything for me with Bluetooth. The earpieces take too long to connect when a call comes in or I make a call and some even auto answer when they connect which I don't want. I wonder how much battery drain Bluetooth and GPS use if left on but idle?
Sent from my EVO4G using Tapatalk.

Yeah, it would have depended on how long it took to pair. Still try checking the apps through systempanel after a few hours of non-use though. That should help.
And gps doesn't use much until its being used for something, but bt is a constant drain.

Double post

On my old tp2 Bluetooth didn't the battery much. I guess it does on the evo
Sent from my EVO4G using Tapatalk.

OK so I have been running for the past day and 1/2 without blutooth turned on.. I only have 3G and GPS turned on. Still it seems the battery drains faster then it should. I look at SPARE PARTS and it doesnt show anything out of the ordinary on PARTIAL WAKEUP. I have SETCUP to 384/245 when screen off. I do use SYSTEMPANEL to look at what is running and it does show a LOT of stuff such as SLACKER, SOUND HOUND, JUICE PLOTTER, etc... what else can I do for battery life.. I left for work at 8:00 and when I got to work at 8:15, the battery was already at 90% without doing anything....
Aldo how much battery drain does BT take if I leave it on? its a pain to remember to turn it on when I get in the car and turn it off when I leave...

[Q] SetCPU and JuiceDefender, are they needed anymore?

Hello,
Title says it all...
I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.

I agree... I got about 27 hours of life out of my battery without set cpu or JD (i've never liked JD anyway because its like putting my kid on riddlin)

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.
Where Helpful:: In advanced settings, you can provide a 'night schedule', wherein during this time, JD will disable mobile data, and thus polling, so your phone will not go out and check for mail, FB messages, Tweets, etc. Otherwise, mobile data is off unless you 'wake' the screen for some reason. Or another feature that 'trains' your wi-fi to only activate when you are at home or a 'recognized' wi-fi spot. These are a couple examples, there are others.
Where it MAY be Helpful: JD can disable mobile data for a custom # of minutes (10/15/30/60) and prevent background sync during those periods. It will awake, allow the sync, then turn mobile data off. Now some apps may only sync in these intervals anyway, but unless they're all syncing at the same time, you could have lots of 'up' time. Some of this may not 'wake' your phone from Deep Sleep, but depending on how sloppy the code is, it might.
Hope this helps.

I think really depends on the ROM you are running. ViperROM has a script that changes the CPU speed and governer on the fly. So no need for SetCPU there. I'd say Juice Defender can still come in handy with turning data off when you aren't using it.
My 2 cents. Your results may vary.

I use ultimate. I did run a night schedule, but that kind of points back to my original observation... I'd have night setup from 11pm - 7am and see a horizontal line for battery during this time (wow JD is really working)... BUT, with it uninstalled, during the same period of time 11pm - 7am my battery was also horizontal line... So did it really do anything? I'm on wifi at my house so when I'm sleeping the phone is wifi and not constantly pinging the mobile network (does that make a diff. being on wifi)?
I also did like the wifi only when home setting.
With ViperRom, I probably don't need set CPU anymore... Maybe i'll throw JD back on.
One question.. were you running the beta JD? I noticed the beta would always throw errors in the log stating i needed to uninstall, reboot, reinstall (I never did) anyone else have that happen?

These numbers sound like you have the radio off and don't turn your display on. Pretty amazing numbers otherwise. Would love to know the rom + kernal you're using
edit: I see the post above you mention viperrom. Typically if you have data turned off and display off any device will last days. My OG evo lasts for around 48 hours just sitting there. Still really impressive if you're using your phone within that 30 hours

I've never tried the beta; I started with standard, upgraded to Premium, then eventually upgraded to Ultimate (I use the 'Customize' setting, but rarely the 'Advanced' config).
I hear ya on the night-time wi-fi thing. But with this particular phone (and before I rooted and changed ROM/Kernel), on some nights I would be connected to wi-fi and get ZERO CPU sleep time, other nights it would sleep - I have no idea why. It is conceivable that if the only polling your doing is e.g., Gmail, that either it doesn't happen at night, or it happens in such a way as to not knock the phone out of sleep (it IS Google's OS after all).
On a related note, I'm using K-9 mail (my primary mail is Yahoo); it throws wake-locks all the time (set to poll every 15 minutes), but they don't seem to impact battery life or take the device out of deep sleep which is why I suggested that case above.
One other item I like about JD is the ability to permission each and every app for wireless/network access; obviously mail, calendar, phone, etc. need it, but some apps simply don't, and I've been surprised when I set it to 'notify' and some random game pops up seeking network access. Looking for an update? who knows, but I lock 'em down anyway.

Interesting thing is with the latest JD build it has the bluetooth settings, so i can leave my headset paired, but the phone disconnects while not on a call and then when i get a call, it turns on... kinda cool.
In regards to the permissions... do i need to give the email applications permission for enable/screen off? (so that I'll still get the notifs?) or just enable (as in when screen on).
thanks,

wifi goes sleep even setting policy to "Always On"

I have set the Wifi policy to "Always on".
Many times (but not every time) when my One X goes into sleep mode, all data connections don't work. I notice it because I feel so strange there is no notification from Whatsapp and Line as usual. So, I press the power button and see no data connection at all. After a few second, 3G data connection appears but no wifi. Wifi then replaces 3G a few second later.
It usually happens and I feel so annoyed as I lost communication with my colleagues when One X is sleeping.
Is there somewhere in "Setting" that can override the "Always on" in Wifi policy? If I miss it, please let me know.
I feel very disappionted with my One X as it contains a lot of bugs.

It's happening to me too, it's very frustrating because when turned on it show as connected while it's false.. and i'm unable to browse/etc without re enabling wifi manually.

Same issue on the One S. This is most likely a driver related problem or something. I think the next firmware update should fix this, but if anyone of you can provide a hotfix or something I wouldn't be sad

Getting the exact same problem.

I have not noticed this so far.

same problem with wifi....and in the nights my Data also gets switched off after sometime of inactivity...couldnt find any setting related to that....do any of you know any hidden setting for it?

Yeah it happening to me as well. It could be kernel related.

Same Here

Mine is opposite, I want it to sleep on screen off but it keeps reverting to always on. Quite frustrating as it is the major cause of my battery loss

yeah same here, i've tested both over night and less battery used on wi-fi than 3g

I cant connect to my home wifi, it show connected then disconnect immediate
it no usaable now in my house

I just noticed this, too. Really annoying when you suddenly stop getting any notifications for E-Mails etc.
This is also not fixed in 1.28 :/.
I seem to only have this during the night hours, though. Like there is some sort of "Quiet Hours"-function but they forgot to put it in the settings >_<

I think this is the special Sleep Mode kicking in, and the WiFi Always-On is overridden by it.
When I turn the screen off, I can still ping my One X over the network. However, after some time (maybe 5-10 mins) it no longer responds and has dropped its WiFi connection.
The Always-On WiFi option has only ever applied to when the screen is off. The sleep mode thing is new and not related to android itself - an HTC hardware thing by the look of it.
Maybe it's fixable in the driver software, but I believe the "WiFi always on" function is behaving correctly - it's the new sleep state that is breaking it.
I could be wrong, but that's what it looks like.
If someone has the time, try setting up a PC to continuously ping the One X and see if it keeps it from going in to sleep mode.

Hello Dave,
Your analysis is quite impressive,
I also started dealing with this from "Special Sleep Mode" perspective.
I have got the FOTA, find data in my signature, and still suffering from the same issue.
To summarize my findings let me brief it:
When I first got the update, the problem seemed to be solved
I kept connected to my home WiFi router for several hours and got notifications from Whatsapp and Twitter
I thought the problem was solved and the bug was fixed, as I kept seeing my OneX on the WiFi Client on my router's managing interface on my PC
I shut down my phone, WiFi was on, and turn it back on
WiFi kicked in and connected with no problems,
An hour after, I sensed something wasn't good, notifications were silenced
I unlocked my phone and checked the status bar to find there were no DATA connections at all, nothing, no WIFi no Mobile Data, the usual bug
Now I started to think,
I Have got this problem after a full shut down, and at a battery below 15%
One thing to add,
I turned my phone off with WiFi enabled and when turned it on WiFi kicked in.
Now I am monitoring on the following basis.
I clicked all WiFi hot spots previously saved on my OneX and chose to "FORGET"
Connected to my preferred hotspot
Monitoring the WIFI, with battery over 15%, seems to be very healthy, more than an hour on sleep mode, and WiFi is on, uninterrupted and VERY CONNECTED
I will keep monitoring the behaviour till battery fall under 15% and will report back
I'll make sure to turn off WiFi before shutting down my phone if I have to, this is to eleminate the other variable and keep concentarting on one variable "Battery percentage"
A point to add:
On my previous Gingerbread SensationXE, there was an option on Settings> Battery to control phone's behavior and stop background sync and other activities when battery fall below a pre-defined percentage.
Default was 15%
I can't find this option on my One X, IceCream Sandwich
That's why I started to analyse the problem from the perspective of "Special Sleep Mode - Below 15%" bahaviour.
I will report back as soon as I have results.
Thank you
Update:
Started to experience same issue when battery falls below 50%.
All DATA gone down, no WiFI and no Mobile Data.
Charged my phone to 73%, "Forget" all WiFi network.
WiFi off
Monitoring Mobile Data only.
Mobile data gone down after 30 minutes sleep mode, 73% battery
Connecting to WiFi, and started monitoring WiFi
WiFi + Mobile Data gone down after 30 minutes.
Power down phone, and then on, 73% Battery, WiFi off
Monitoring Mobile Data only.
Failed, and disconnected
Failure
I've done a Factory Reset !!!
Update:
No problems on WiFi, nor Mobile data whatsoever for the whole day until battery falls below 10% !!!
WiFi disconnected after exactly 15 minutes, Mobile data kicks in, then disconnected as well !!!
I turn on the screen after 20 minutes to find NO DATA CONNECTION of any kind.
Mobile data kicks in, WiFi replaces mobile data, and start receiving all data dependent notifications!!!

I have the same problem, wifi is turned off sometimes when screen is locked.

Hello Pabson,
Thanks for sharing.
Would you provide more information about your phone's software number, your location (Region, not specific).
Thanks again.

Same here, tried several roms and the same happens with every ROM out there. What is more, I cannot connect to WIFI at work (WPA PSK) but I can connect perfectly to my home WIFI network.
Hopefully this is not a hardware fault and will be fixed.

If it happens on every single rom you you installed, then apparently this is a hardware fault.
What "Base" do the Roms, you installed, created on?!
I mean based on what version of RUU?

same problem here.
I mis the "power saving mode" options like in android 2.3
It might idd have something to do with power savings mode kicking in.

STAMINA Mode not working properly

Hi,
As I remember my STAMINA mode work good in .234 fw.. my Mobile Data connection was disable and resumed when screen on.
But after .244 update.. Stamina mode does not work as before, Apps get stopped when screen is offed, but Mobile data connection is still there.
I have no apps in white-list..
Im bit worried, cause i have enabled mobile data 24x7 in LTE mode, so disabling it when screen is off, will help me on battery..
But i done know whether its the way how Stamina mode works..
If someone can explain me.
Thank you

stamina mode is somethings to enable phone enter into deep sleep mode. But after u turn off the screen and lock, if there got any apps consuming the data in background, so phone cant enter deep sleep.
most probably is Auto-Sync, social messaging apps (Viber, Line, Whatsapp, WeChat, Tango and etc). these will enable the phone always keep awake and using the data.. Stamina mode will only works after screen off for a certain time, will enter into deep sleep. If any apps wake it up, then wont work anymore.
So if u want stamina mode works better, turned off Auto-Sync, Mobile data (if u have a lot of social messaging apps).

Hmm..

But i did a full repair, so all gone. but still its like that.. And no Auto sync as well

I'm same person as you. I'm turned on data, GPS, auto sync all the time.
Normally average I can get 3 hours screen on time with 12-15hours total.
Hope this can be your guide for battery usage life. I didn't active stamina mode due to I need receive email, msg at anytime. If phone lost still can track back.

I have never had much luck with stamina mode, or disabling background processes or whatever and, believe me, I have spent what feels like a total time of 5 weeks of my life on this, as for all of us, trying to get our super smartphones with awesome screens to last more than the waking hours of one day....
Here is a screen shot of my XZL from this morning. (82% battery remaining, 27 hrs of use on battery, screen on time 9% = approx 1.5 hrs in screen diag window I have Auto Sync enabled, and collect emails on regular basis.)
I am using DS Battery saver (pro version but there is a free one to try) and thro custom settings can allow checking for emails at whatever interval I like so, for example, i set DS to wake up (in background, of course) every 20 mins for 2 mins to allow whitelisted email app to check for mails or whatever intervals and apps I want....
SMS and MMS are always instant as are incoming calls (obviously again)
Have this on all my work phones, XZL, GS4, GS3, HTC one etc, and all are now easily able to do two days with what I would call normal usage (3-4 hours screen on per day) emails and calls and the rest all the time
@chuan Hong - why leave GPS on all the time, are you looking at maps all the time? Device locks so fast on GPS why not just turn it on when you need to know where you are or where the phone is? Certain apps will switch it on when signalled to do so remotely...

Thanx al try the app

Srsly man, stop using battery saver apps, that is Not at all required. In fact that app might be interfering with ur stamina mode...
Also, as another person above said that stamina mode requires deep sleep, this aint true(actually, that would defeat the whole purpose of stamina mode). As soon as u turn the screen off, the stamina mode kicks in.
Also, how do u know that stamina mode isnt working? Do u recieve whatsapp notifications after u turn the screen off??
U might wanna check ur stamina mode settings.

Sorry, but I am not stupid enough to run both at the same time! What the battery saver app offers over and above stamina mode is deep sleep so you have missed the point there. For me that is why it saves battery for my usage...
My remarks are intended to offer another possible direction for those who have not succeeded in achieving what they are looking for using stamina mode. For me that is the purpose of this place that we love, xda! Negative comments slagging off others people's posts when they are trying to be helpful are what is rapidly becoming the norm here, and that is very sad...
My remarks are also based on many hours of analysis and research and are, for my usage, bourne out by empirical results!

On a more conciliatory note, sorry if I ranted, you are correct when it comes to the Wi-Fi only tabs and battery usage is worse with an app than with stamina mode. Maybe related to continual switching/seeking of phones looking at 3g, h+, lte in the background which ds obviously removes....

Well friend u r an advanced sort of user... Unlike many others who just download things and complain that their phone isnt working properly... I previously thought that, and u might not believe but there r ppl who use stamina mode and battery saver apps simultaneously.
That's why I said so. I never meant to counter comment u in a negative way. Im sorry if u feel so. I just wanted to convey that battery saver apps r not good for our droids.

oh i turned on gps for all the time because of security.. i've been lost my phone before so cant track it back. now i purchase https://play.google.com/store/apps/details?id=com.myboyfriendisageek.gotya&hl=en apps and installed https://play.google.com/store/apps/details?id=com.nezdroid.lockscreenprotector
smart lockscreen to prevent people shut off our phone in lockscreen there. Useful. If im lost my phone, i can track the location and take the front photo. I can remote control my phone. So i have to turned on my data, GPS all the time.. dont want lost my expensive phone like that.
recommend u to install these 2 apps too. i know myxperia can track our phone too.. but GotYa! got much better features. MOST IMPORTANT, cant let people turned off our phone 1st. Once off, then can flash rom or anything. GONE.so smart lockscreen protector is important and installed gotya! to catch/track our phone

I think you are wrong. Stamina mode should always work the way that it disables mobile data when the screen is off, regardless of how many apps you have running in ackground. that is the whole point of stamina mode. Mine is also not working. I turned it on this morning at 5 am, and at 6 am the battery dropped 3% and i got a notification that i should turn on stamina mode to save battery. The screen was off for that one hour and the phone wasn't in use
