I have cyanogenmod 12 euphoria rom installed.. The cell standby is always number one battery draining source.. I have good screen on time but terrible standby time.. The battery goes from 100% to 0 on 7 hours of night.. I turned on airplane mode which caused improvement but still the radio burns through battery although my Sim card slot is broken and i have no sim cards..
Thanks in advance
Well, with airplane mode on, there should be hardly any battery drain. On my previous device I used to turn airplane mode on during the night and had 0 battery drain.
Have you check to see if something is keeping your device from sleeping?

I'm quite staggered to state that my S3 haven't used a single % of battery overnight, I left my phone at 66% and in morning my jaw just dropped by looking at battery meter it was at 66% i thought it was stuck or hanged so i restarted my phone pulled the battery out and waited for 5 mins and turned it on again and voila it was at 65%(1% lost due to booting)
also my S3 is Made In Vietnam
Isn't this a good thing? Phones don't really use a lot of power when on idle like this. As long as u have a good signal and the radios not trying to pick a signal the battery doesn't drain much. I've left my g2 overnight several times and it hasn't gone down either

Yes its a good thing however my last droid eats 15-20 % battery in night which is bad.
Auto-sync on? 3G/wifi/airplane mode? Wouldn't mind having tiny idle drain myself
Phone is set on 2G network(not on Airplane mode) with wifi and auto sync OFF
I also noticed my SGS3 drains very little at night. However, when idling at daytime it does drain more battery (using System Panel to monitor battery levels).
Perhaps there is some power saving feature that put the phone in a deeper sleep-mode at night? Automatically disabling auto-sync etc?
Closed, we have a thread right here for initial reviews/discussion.
Thank you.
I have Problem With Standby Time .....My Battery After 12 Hours Standby Have 50% Drop.....I install Stock Rom But Itsnt Fix...Please Help Me:crying:

how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection

All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
Hi, I don't know what to do, I'm running 4.2.1 stock on my 32 3G N7. The tablet cannot go in deep sleep because of constant baseband_xmm_power kernel wakelocks. I tried factory reset, but the problem persists. For example with 5h the screen off, there are >4 hours partial kernel wakelocks.
Same here and I'm sick of it. Sometimes my Nexus manages to enter deep sleep but I still see a significant percentage of that kernel wakelock. It also happens that wifi won't shut off on sleep, and I'm talking about when it truly enters deep sleep, and it's correctly configured.
I have the same problem. Battery life is really poor due to this. My LP core is running at full tilt for at least half the time the screen is off, preventing deep sleep.
I found a suggestion that turning on flight mode and then rebooting might help, but I think the problem recurs pretty quickly if not immediately.
Saw a post that said it's due to the modem switching power levels when radio reception is poor. That would definitely make sense in my case — 3G reception fluctuates a lot at home and I am constantly losing connection. I have removed the SIM and will check it in the morning to see if there's any improvement. (Using BetterBatteryStats).
Hope this bug gets fixed in the next update. Almost thinking I should have got the vanilla wifi model
________________
EDIT: Removing SIM overnight doesn't help. Over the course of 8h screen off, baseband_xmm_power was active for 7h 46m!
I'm having the same problem, only when mobile reception is poor. Unfortunately, my mobile coverage at home is currently near-zero, which makes using my tablet as an alarm clock a dicey proposition unless I plug it in overnight.
I've got a problem with WiFi consuming too much battery. I fully charged my phone and did not touch it while it was connected to WiFi. After 2.5 hours, it was at 88% saying most of it was consumed by WIFi and standby mode.
I have "WLAN optimization" turned on. I never had this kind of problem before with other phones - does anybody have an idea what I could do to reduce the battery usage?

maybe you have apps synchronizing and draining the battery, try greenify app to hibernate what you dont need when phone is on standby mode.
Running LineageOS 15.1 on x727 phone. The battery drains 50% over 8 hours when the phone has been shutdown. Has anyone experienced this problem. Is this an OS thing or a firmware thing, or something else?
Bro. That's my phone's cancer.
Look. I've tested <almost> any rom out there, Nougat Roms, Oreos Roms, Pie Rom... And I had Battery Drain in deep sleep mode... I lost 15%-30% on overnight.
I though was a Battery issue and its gonna die so, I did a some test.
First, charge your phone (up to 90% its ok) and Turn it off complete. Let it turned off at least 8hrs (overnight for example). Then turn it ON your phone. You should loss ~3% of Battery. That its a good battery signal. If you lose 10%+ your battery is in bad condition. Another signal of Bad Battery is your battery get warm a lot even screen turned off.
What I did? In my case my battery its still good and look like its a system battery drain (yes, in any Rom what I tested, even with grenify, snaptime and other mod like kernel and thermal zip)
Also, my phone do not spend battery while its on screen, the issue its not get into in deep sleep, and that is the problem...
I am using a DotOS 2.4 (Oreo Rom) and I did not flash any Kernel mod. Just magisk+Dolby.
Also installed *DS Battery Saver* and setting in "Agresive Mode" that force to sytem to get into Deep Sleep mode and I choce what app keep alive on "white list"
Before I got -3.5hrs SOT Now I get around 5.5hrs SOT of battery (I use YouTube and Instagram/WhatsApp a lot //Not Facebook and play game, never)
Also I put the phone in Airplane Mode on overnight to avoid innecesary Battery drain.

Try to install last AICP Pie, switch to 3G instead of 4G ( do it in SETTINGS --> Network & Internet --> Mobile Network ... etc. choose WCDMA preferred, then dial *#*#4636#*#*, tap Phone Information, tap Preferred network type, choose WCDMA preferred ). Works great for me
