Battery drain during night - Samsung Galaxy M31 Questions & Answers

My battery is draining by 8-10 percent during night in about 6-7 hours in stand by mode.
I have even tried switching on the 'maximum power save mode', but no change in battery drain.

That's not normal! Do you've airplane mode on or off?

it's probably a network issue, it happened to me as well, the network signal is weak on this phone i guess, something that helped is switching from (4g/3g/2g) to (3g only)

[Q] Battery usage issue: battery cronology and force close

Hi, i have an issue about battery drain here in froyo with official rom and speedmod kernel.
I notice a 4% per hour in stand-by drain.
If i check with *#*#4636#*#*, under "battery cronology", watching network usage i find something strange...
the most used application , more than email and everything else, is called "0".
When i try to click on it, watching details, i have a force close.
Is there something i can do ? i wouldn't wipe all data to check if i resolve...
Thank you
The same for me.
I have a big battery draining when the phone is on stand-by. For example this last night, i fully charged it, and in 12 hours the battery drained a 10% without using it, with juicedefender installed and configured to auto on 1 minute every 15.
I think that i dont have the gallery sensor issue, but my battery drains more than i think is normal, and i have the "0" under network usage, and get force close when clicking it.
It's the same for me as well..anyone knows what the '0' is??
I'm on JPA build.
same thing happen to me.........try to off your data plan and it will save lots of your battery juice.........unless u are really checking email on your phone of course this doesnt help!!
is it normal to lose 20% charge in standby within 4 hours? i have almost everything off and it still drain my battery like crazy. Sync is off, data is off, wifi policy is sleep when screen is off, gps off, bluetooth off. Anything you name it i have it off. I have "spare part" installed and looking a the stats i don't see anything else eating the battery life. Only thing i see under other usage. is "Running (33.9%)", "Screen on (9.3%), "Wifi on (100%)" "wifi running (61%). Could it be the wifi on at 100% eating my battery?
same problem here
if data is ON overnight, battery drain is very high, like 20% in a few hours (5-6h).
if data is OFF, battery drain is almost 0 (zero)
in iphone 4 when my data was ON overnight with 3G and PUSH turned ON, battery drain was somelike like 3 or 4%.
Something is terribly wrong.

battery usage in sleep mode

Hello,
I noticed that the phone continues to use the battery a lot while it's in airplane mode and NOT awake.
For example last night I went to sleep and put it in airplane mode with 67% of battery, when I woke after 8 hours the battery was at 58%. It dropped 10% for no reason (with my other android device if nothing is on it never drops a point all day!).
Viewing the battery stats I see that the in those 8h the signal was off, the screen was off, wifi off, the phone was asleep the whole time but still the battery dropped. How is that even possible? What used the battery if nothing kept it awake?
I'm using cm7 KANG

15-25% overnight battery drain versus 3-4%

According to the Battery thread in this forum, some people experience a high overnight battery drain, and some get a low one.
I am currently a member of the high club. For battery testing, I have most things turned off, like location services and google now. Last night overnight drain (8 hours) took the battery from 76% to 58%... 18%. On my previous phone, the HTC One, the overnight drain would be around 6%.
I am curious about the people who are getting low (~5%) overnight drains. Do they all have Wifi off? What is their secret?! Do tell.

Install better battery stats to monitor what's going on. I think the one night I left it off charge over night I lost maybe 6-8% but I slept for like 10+ hours. This is with google now on, gps on, wifi on.
What i'm testing now that I think will actually improve batt life is having wifi turn off when display is off (unless plugged in). I think I noticed less idle drain at home when I did this but it was temporary. Giving it a shot over a few days now.
I leave wifi on and I get less than 5% drain. Nothing syncs when my screen is off except notification weather pro every two hours and Yahoo weather

Personally I think the X and new droids have idle drain issues. Even when better battery stats shows nearly 100% deep sleep overnight, I still lose 8-10%. In comparison, on my HTC One mini, which is setup EXACTLY the same as my X in terms of installed apps, syncing accounts, running services, etc., I lose only 2-3% overnight. The number of people complaining about the issue seems to confirm it is more widespread than on other recent phones, as do the countless screenshots showing unusually high android OS usage in battery stats.

I honestly believe it will be patched with the Camera.
I'm having the same issue. People are reporting crazy battery stats with like 20+ hours of use 2+ hours of screen on and like 20% battery left. I get MAYBE 12 hours of use and 2 hours of screen on and 20-25% left. My mediaserver is keeping the phone awake for almost an hour+ each day, and without root I can't figure out how to stop it. I always have GPS/Google Now/Bluetooth off, too.
I thought the drain was related to Wifi. But last night WiFi was turned off for the night and I still got 18% battery drain in about 8 hours.
Wifi at home and overnight. I get about 5% drain... however, the wifi at work kills my phones battery with the wlan wakelock.
Maybe there is something going on with the X and certain wifi networks?

Interesting theory but my overnight idle drain was approximately the same on both LTE and WiFi. 10-15%.

How about turning off all radios (flight mode) and observe battery drain at night. Then turning wifi while on flight mode the next night and see the battery drain and so on until you can pin point what causes the most drain.

Inaccurate battery %??

After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Yeah i could try to calibrate it. Im a little confused on what you do to calibrate the battery (ive read way to many opinions on this). Can you please tell me the steps.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 5T's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
From last 2 nights....i got 3 percent standby drain when I put my phn alone for 6 to 7 hrs with wifi on
Same here 3 percent over 8 hours at night. Seems like they fixed the drain problem of Wifi in comparison to Op5

Yes you are right
3 percent is almost negligible
10hrs standby with WiFi on, 4% (went from 97 to 93.) Pretty good I'd say.
3% as well no wifi
My device is draining battery little faster when using normally and on standby it is draining nearly 2% per minute while on 3g+ mode . Is it normal.. ?

of course it's not...
1% every 3 hours on idle.
OOS 4.7.4, wifi on

Absolutely not, I would prob do a clean flash again or something is killing ur battery, ur phone must be on fire draining 2% in one minute, I get about 1% per 6 min using Chrome and about 4 or 5 min using facebook

Just wifi or is your mobile data and location on too?

I have data off, location on, wifi on
Sorry guys .. It was a typo.. I meant hour. When I leave mobile internet on during standby I get 2% drain per hour when switched off drain is 1% per 2 hours. Location is off whole time.
So a H+ network drain battery faster compared to a WiFi ?

Location set to data saving, 4G data remains switched on as well along with WiFi
5% without wifi and data...I hope Oreo fix this...
how about when u guys use it until the end of the day while the phone screen is constantly turned on and off? 6h+ seems to be the average for sot but I haven't seen anyone post their idle times yet except for when it's during an overnight sleep
My friend has a 3t and his standby his pretty bad. He is on Oreo though....Does anyone else get a huge battery drain on their 5t?
My battery is draining as quick in standby mode as it is when I'm using it! I'm losing about 3.5% /hr over night. That is really my only complaint.
I'm leaving everything on. WiFi/data/ location/ Bluetooth.. shouldn't have to switch it off tbh.

If you live in an area that doesn't receive particularly great cell service, leave data and location off on your 5T. When your phone has to constantly search for a good cellular connection, it will eat power like a New Yorker eats a hamburger at a baseball game. And if a sub-optimal cellular connection in your area is the case, then 3% per hour isn't half bad...my Droid Turbo 2 would drain 11% in the same timeframe.
If this isn't the issue, then check the power consumption of the individual apps you have on your phone to filter out problem apps that may be draining your battery rapidly. If neither of these methods work, you may have to resort to factory resetting your phone, or RMAing if nothing fixes the issue.
So, I've narrowed it down to being a WiFi related issue. Something is running when WiFi is on which is preventing the phone from going into deep sleep properly (if at all).
When I switch WiFi off overnight, and leave everything else on (data/BT/NFC) then my drain goes from 3-4% / HR to around 3-4 % in 8 hours.
Can't figure out beyond that yet though.
