Battery problem

I know the battery life is not the best on this phone, but today my battery died very quick.
I fully charged it in the night, than unplugged my phone at around 12:30 AM when 100%, then I used my phone to some calls at 9:30 AM.
When I checked my phone at that time, the battery was down to just 51%
I just have a normal Wallpaper, Bluetooth and GPS turned off and only used the phone for less than 15 mins top since being fully charged, how did all the battery die on me ?
Android Version 2.3.3
Kernel Version 2.6.35.7
Build# VillainROM 1.1
Please need help ..

Did you install the stock XWKE7 kernel like it says in the OP in large red writing (IIRC). You could also install the XWKE7 CF-Root package

Hmmmm .. Actually I have the "XWKDD" I'll try "XWKE7" then give you my feedback after testing it for couple of days.
Thanks ..

OK .. here's the thing, I fill up the battery at 11:00 AM with 100%.
I made 2 calls at 11:33 & 11:44 AM for several minutes.
I record several videos for several minutes in HD & take some photos as well. By the way the wifi, data network, GPS and bluetooth are off. It's also in auto brightness.
At 07:44 PM the battery reached 77%.
At 12:00 AM next day I surf the market with wifi for 30 min and left the wifi on with no apps running in the background. At 12:00 PM the battery was died.
In the other hand, the iPhone 3G with the same settings in the same time when the GS2 is died the battery was 45%. The old iPhone 3G completed a day and a half.
So, what do you think ?

smaller screen, different technology, less pixels. The iphone doesn't do multitasking. It also doesn't power 2 x 1.2ghz processors. It powers a (I think?) 400 mhz. Those are some starters

Could you post a screenshot of your battery stats?

Hmmm .. reasonable. BUT, still most of the reviews say that the battery can reache 12 hours in heavy duty.

I have recently fixed my battery issue. I was getting aound 8 hour the first 3 weeks. But after freezing a single process "wifi sharing" I am now getting 20 hours. My usage is the same. This wifi sharing process would run even when wifi was turned off and also on all the current firmwares. I've spend the last two weeks testing all kinds of things, taken thousands of screenshots on the way.
Let me know if you need more details.

I tried to freeze the "wifi sharing" through Titanium Backup but it need the Pro version is there another way to freeze it ??

My drain, with latitude.

I really can't understand all this complaints about battery. Here is a shot of my stat. I didn't use the phone too hard in this period, but it usualy can stay for almost 2 days with 1 charge. I never rooted the phone.

Normal you don't have the problem, your phone isn't awake, how do you setup your phone (wifi, sync, etc)?

Well, I just made wifi to turn off in idle. Bluetooth and GPS are on all the time, sync with google account (no idea how often it do the sync), weather refresh is every 2 hours. Mail accounts are setted to manual sync. No facebook at all. KE7 firmware.

Manual Sync may be the key, i'll try.

Any ideas why my battery suddenly dropped like this and then even started increasing without charging the phone ? lol

discharge ur phone til it shut down once to calibrate (just once) then charge full

I'm going back to the stock ROM and test it. If it's drain my battery as will as the Villain ROM (hopefully not) that means either the Samsung ROM or my battery has a problem.

Battery Drain - Again! events/0 and suspend !

Hi,
I have on my Samsung Galaxy S2 as well as on my Samsung Galaxy Note a huge battery drain caused to 2 processes : "events/0" and "suspend".
I have already read a lot of threads concerning this problem, but without finding a solution.
I found out, that I only have this bug, when activating my Wifi connection (on both devices). I tried every wifi sleep policy, still getting same results.
So finally, my Android OS battery usage is more than 50%, even more than my display.
Does anyone know a solution for this problem, considering that now I'm sure that it's linked to the wifi activation on both phones. (I did a factory reset and there was no battery drain until I activated Wifi without having any other apps installed, besides of System Panel to monitor....)
Thanks in advance,
Regards,
Ben

If your phone is rooted you should 'freeze' or remove the apps "Wifi sharing manager" and "Wifi sharing" with Titanium Backup. Fixes your Wifi-problems.
It's a service that looks for other Samsung Wifi devices constantly when Wifi is turned on, thus draining the battery.

No, my Phone isn't rooted. I was not sure if I should or not, considering the warranty problems. Is there no other way?
A lot of other users don't have this problem, I don't get why I have it-.-

As far as I know, it doesn't really void your warranty as long as you do it the right way and unroot your phone before you send it back to Samsung (if problems occur).
Someone correct me if I'm wrong.
As an alternative you can disable WiFi when you are not using it with apps like Green Power and Juice Defender (although I strongly advise Green Power for it's ease of use).

Thank you.. But there has to be another way to solve this problem, because people I know don't have this bug... without using any batterysaving software. :/

I guess it's a native issue of your device...

In the first week that I got the Note, the device is eating up about 10% of batter per hour even when idle. The way that I use this Android phone was no difference than other Android devices I have used. When checked the battery usage, I was stunt to find that the Android OS was using 90% of the battery. Funny is that the screen showed a usage of 20minutes, while the OS showed a usage of almost 3 hours.
Soon after, I decided to do a factory reset due to other reasons. Some how this problem went away and the usage is back to normal. I don't know what happened, but in my case, it solved the issue.
Also I don't use the Note as a phone, but rather as a mini-tablet when I am not at home. So I decided to put the device in Flight mode when it is not in use. In this mode, the device hardly uses any battery. For example when I went to sleep, the battery was at 79%. When I woke up 7 hours later, the battery still shows 79%.
Hope this help!

How about you stop ASS-uming about devices that you don't own. The Galaxy Note is faster, smoother, lighter, and more portible than your Motorola tablet. The only tablet that can match or even outperform the Note is the Galaxy tab so have fun with your soon to be obsolete tablet.
OT: Your issue may be fixed with a factory reset.

Did you try 'Green Power'?
Did you try the app "Green Power". It is pretty good and promising. It will turn off Wifi / 3g while it is not using, it save much power. The paid version just including the 'night' mode.

I'm suddenly facing this issue. Have had no problem with the battery so far. My battery went from 40% to 15% overnight with the screen off and wifi off. :s

Edit one more time: I found the battery draining really fast just now too: 15%-12% in about 20 minutes.
Clearing the RAM seems to have stopped that though.

I really do think it's the wi-fi sharing/manager processes. I've frozen mine to see if that makes any difference.

It's exactly the same for me, with the suspend and events/0 processes...

I solved my problem thanks to a tip on this forum. I just did a factory reset for my ohone, and then reflashed the firmware. Its working great now

ok, but what version?
I'd think it's pretty relevant to know what android/fw-version you're all using? I'm on Samsung's original 2.3.6 and have no issues...

No, its not. Coze I've upgraded to 2.3.6, and then downgraded to 2.3.5 again, and my problem was still there. Only a factory reset solved my problem.
By the way, u can notice something is wrong by the amount of heat generated while using the wifi, or by how slow pc usb charging could be. It even used to discharge when connected to pc!
The amount of heat was a very strong indication that there was something wrong.

Still battery drain
Hello all,
as of 26 march 2012, I still have something problematic on my samsung galaxy note. I flashed last Open German firmware (LC1) (from samfirmware). The phone is rooted, and as far as I noticed the "suspend" process is still draining the most battery compared with the display ratio. I tried to wipe everything, I downgraded back from LB1 to KKA with Odin, wiped, flashed LC1 and reinstalled onyl paid apps (i.e. not with no advertises). I turned off the Wifi but the susped is still there, eating 63% of resources.
There are not special kernel wakelocks... any ideas on how to go ahead?

I have a standard non rooted rom. I also faced sudden battery drain, but use the following solution -
Folders - keep to the application page not home screens
Backlight - off when inside, 50% if outside or on charge (auto drains faster)
Browser - use one of the low power saving mode
Screen background - live wallpaper eats battery. Use a dark based wallpaper , use much less power
With all the above battery is fine. GB 2.3.6.

I've had the exact same problem as the topic starter. Android system running over 90% in standby and suspend and events/0 running at 100%. I had this problem on stock XXLA6, on Darky V3.3 XXLA6 and Rocket V23 XXLC1 and after a number of full wipes.
My wifi wouldn't turn off in standby and setting different sleep policies didn't do a thing.
I removed the Samsung Sharing app, installed GreenPower and set it to turn off wifi and 3G/data as I don't need sync when it's in standby anyway.
All problems are gone now, after an hour in standby I still have 100% charge and after browsing for 5 minutes it lowered to 99%. Suspend and events/0 no longer run when the phone is in standby, wifi is turned off and Android System is at 4% now.

Battery drain when idle

Hi Guys,
I just got my LG G2 and so far lovin' it. I just noticed a battery drain problem though.
I left my phone at 87% when I went to bed at around 12am, this is with WIFI and Mobile Data off. When I woke up at 7:30am, it was down to 71%. I checked BBS and the number one item under Kernel wakelock was bam_dmuc_wakelock.
I've read multiple threads regarding this but have not found a concrete solution. One thread (http://forum.xda-developers.com/google-nexus-5/help/-t2688930) said that this is normal and some app may just be causing this.
Here are the current apps installed on my phone which were also the same ones installed on my HTC One X where this battery drain problem does not exist:
BBS
Dolphin Browser
Facebook
Instagram
LinkedIn
KK Keyboard
NBA GAME TIME
Olympus Image Share

Can anyone help me with this battery drain issue of mine?
Thanks in advance!

If you rooted, you can try Greenify to identify the culprit.
Maybe you can check battery settings to see what is eating it up?

bam_dmux is for mobile data so anything that keeps mobile data connection open it will show up. Stands for broadband access multiplier demultiplier.
so the problem in question should be simple, what app is continuously using your mobile data connection causing the bam_dmux_wakelock

The thing is, my mobile data is always off when I sleep. Is it possible that Whatsapp and Viber is causing this? I mean even though mobile data is off, can they be trying to look for a connection thus causing the wakelock?

BTW, I installed Deep Sleep Battery Saver and tried it last night when I went to sleep at 12am. When I woke up at 7am, the phone only discharged 4% now.

ive had issues with facebook eating my battery on a bunch of devices. when removed i see a dramatic change in battery life. that is my experience, and may or may not be concrete enough to say that it would be the problem for battery drains.

well like they mentioned earlier you can try greenifying whatsapp/viber or other apps(different apps on a daily basis) to try and find out which app is cause the wakelock, but remember that if you use any of these on a daily basis then greenifying them wouldn't be a good idea(unless you only greenify them when you go to sleep and when you wake up you ungreenify them)

I'd probably try your suggestion about using greenify. I usually use whatsapp and viber a lot during the day. My only concern was the amount of battery getting drained at night when I go to sleep so I guess greenifying them at night does make sense.

Try uninstalling the stock facebook app. It was murdering mine.

Sorry for my question, but how do I do this?

I've noticed that my bluetooth has been contributing to the battery usage. Even though I haven't been using it and has always been off. From the screenshot, it's been awake for more than 7hrs.

yes but its not an actual drain you can see on the top it has only wasted 5% battery(in 7 hours that doesn't even amount to 1% an hour), even though its off it remains in a low energy state(idk why it does though) if it were actually draining battery then the cpu time would be almost the same as awake time(somewhere around 5 and 6 hours) and percentage drain would be higher but I have noticed that after about 2 months on kk(for me atleast) I had started using Bluetooth a lot once I got kk whether to stream music or connect controller to play emulators my Bluetooth doesn't false positive anymore instead it either shows the actual time it was used for(usually a couple hours every day sometimes 3 or 4 out of lets say a day I got 14 hours total use) and another thing I noticed is if I leave it off it will give me the false positive or if I leave it on all day and let it connect/disconnect to the different devices gives me actual usage time

to change kernel speeds you need root/custom kernel and I don't know how to do the battery calibration test

I think I found the problem.
When I leave my phone on during the night, I turn mobile data and wifi off, but my connection is still LTE. I was noticing about 10-15% drain as soon as I wake up. What I tried was to set the phone to just use 2G (GSM), still leaving mobile data and wifi off. I woke up this morning with just 3% battery drain.
It's weird though because I get very good LTE reception so I don't think that a poor LTE connection was causing the problem.
Does this mean that LTE really consumes that much battery?

Fyi, since I woke up and turned wifi on, the battery has only went down by 1%! Something is not right. How can it drain so much without using it and almost none when I actually use it.

Which hardware and firmware version are you using?
Do you have cellular data connected when WiFi is off?
Does the battery graph show constant system awake time during these periods of high drain?

Hi. I'm using FRD-L09 and EMUI 5, build FRD-L09C432B381.
No wifi, no mobile data turned on. All apps closed.
Yesterday I left it at ultra power save when it was at 12%, after I woke up (around 6 hours). it was off. Don't think that's normal either.

Sometimes I have the same problem. Overnight phone drops 25% of the battery.
What I found useful is to turn off Wifi+, Link+ and in GPS location (3 dots -> Search settings -> turn off Searching for Wifi and Bluetooth). In fact that will stops searching for Wifi, while Wifi is toogled off.
It might help you, I think this is Android 7 issue, since most people complains about heavy battery drain when not using the phone. Noone complained when using Android 6.

This isn't normal, but at the same time it is... I don't think any one person has figured out the real reason why, but many of us have had similar battery drain for seemingly no reason. I simply backed up my data and factory reset the phone and haven't had an issue since. Others haven't been so lucky.
Can you take a screen shot of your battery graph so we can see if your system is awake during the drain?

I have update B381 and u have this problem with battery drain for my is very bad battery life update B360 was good for battery life.

I found the high Idle battery usage some what related to the phone keep search for upgrade and the process "android OS" was consuming around 50% all the time.
After set these two setting, it fixed the battery drain and "android OS" only use around 20%. Now it remains 100% battery for 10 hours standby.
1) Setting->System update ->(three dots)->Update Settings->Wifi auto download (Disable)
2) Setting->Battery->(Setting icon on top right)->keep wifi on when sleeping->Never

I did as everyone suggested and turned off auto WiFi and bluetooth search and auto WiFi download of the system updates. If I turn off keep WiFi on during sleep, I don't get any notifications from messaging apps, so I won't do that. I've also only left Messenger, Viber and Whatsapp in the whitelist of programs that will be closed when screen is locked.
Here is the most recent screenshot of the battery usage.

Try factory reset and wipe cache. Screenshot tells us that your phone is awake when you are not using it.

Okay, I'll try later tonight and reply tomorrow if anything's changed.
p.s. Any good full backup apps?

Just use the backup tool that was loaded on the phone. It works nearly perfectly to backup all your texts, call log, apps, settings, etc.

Looks like it tried to sleep when you went to bed last night, but something woke it up early in the morning and it never went back to sleep. Find out what that was and you may solve your problem.

If you have data, you still get notifications.

I did as everyone suggested and turned off auto WiFi and bluetooth search and auto WiFi download of the system updates. If I turn off keep WiFi on during sleep, I don't get any notifications from messaging apps, so I won't do that. I've also only left Messenger, Viber and Whatsapp in the whitelist of programs that will be closed when screen is locked.
Here is the most recent screenshot of the battery usage.

As a test, I created a Magisk module that freezes all of Huawei's system power management apps and superfluous services. I just loaded it today, so it'll be a few days before I can provide feedback on if it improves battery life.

I backed it all up and am wiping it tonight but I was thinking. Perhaps it's not a good idea to restore the data yet? Maybe I should try a night with stock settings/apps to see if that makes a difference, then restore all and see if there's any difference.

Honestly, I wouldn't expect that experiment to provide you with any useful info. You will naturally see more battery drain once you have your apps and services running because more will be happening in the background. Reinstall everything and use your device normally to get the most accurate comparison to your previous battery life.

Try factory reset and wipe cache. Screenshot tells us that your phone is awake when you are not using it.

Factory reset I know how to do, but how to give the wipe cache?

IIRC, the cache should be wiped automatically when you Factory Reset.

I like to do it manually. Turn off the phone. Hold Vol + and power button.

I wonder how the battery drain overnight will be with the new custom Roms which are out.

Trying to find the cause of my idle battery drain (Exynos s10+)

I've noticed my s10+ Exynos has some pretty heavy idle battery drain. As you can see in this image, 2 hours of idle time amounted to 10% battery drain, but I can't seem to find the cause of the issue.

- I'm running the device on WQHD+
- OSD is set to tap only, so it only activates when I touch the screen
- Power mode is set to "Optimised"
- I've turned on Adaptive Power Saving to see if that made a difference
- Have emails set to sync every 3 hours
- Night Mode is on
- Did not receive any notifications in the time screenshotted
Any ideas on what I could do to sort this out?

I had a similar issue, what fixed it for me, was to erase system cache and then reset the battery calibration readings using the command *#0228# and then I turned off my phone for a while and turn it on before going to sleep and left it on airplane mode and Bluetooth to see any battery drain and so far so good.
Also in this thread in the last post of that page there is a solution that apparently works.

Will try that out, does my device have to be fully charged before running that command?
Also, have you managed to test it without Airplane mode on?

Can you install cpu spy and see if your phone goes into deep sleep? It seems to be the reason for battery problems in exynos variants. Try to follow some suggestions in this thread:
S10+ No Deep Sleep?

Also had problem with idle drain + also made cache partition reset. Problem gone. You should try it

My drain is around 2-3% every 10h but I will definitely try that

That is a good number, for me the real test will come today when i go to sleep and wake up seeing home my device is, right now it I took it off from charge at 65 around 2-3 pm used it and now it is at 54% almost 6pm and my phone goes to deep sleep, as accubattery shows.

Do you get that drain meanwhile using the phone with all active, signal, wifi, bluetooth, location, etc.

I'm using a custom Bixby routine and other settings to:
-airplane mode until 6am
-enable all services again
-force updates
-run optimiser services
-restart
By whatever time I wake up the phone is good to go, if it was on battery it loses what I said, maybe that's why the drain, I'm not completely sure but it

If you are draining 2-3% in airplane mode I think that is normal, if you are losing that with all services, your phone battery is amazing

Tried that now drainage is much better, 1% an hour. Not sure if that's still high or not though?

Besides turning on airplane mode, what do you think I should try? I downloaded that CPU app, and my device does go into deep sleep when idle so I don't think that's an issue for me

I wouldn't do airplane mode. Try with Do not disturb. It seems to work better somehow.
Check CPU Spy to see, how much deep sleep you're achieving with one and the other.
Also:
- disable all the apps you don't need + background data / activity (esp. preloaded Facebook, Linkedin etc.)
- you can try using Kiwi Browser (complete black mode) instead of Chrome (then disable chrome).
- switch off smart stay, turning on display when lift off, AOD
There's plenty more... but as far as my stats go with those settings:
- around 10-12 hrs SOT with 2-3 hrs youtube, 2 hrs browsing, 1 hr spotify
- approx 1,5 day of standby with that amount of SOT (with less frequent phone usage i got 2 days worth of battery)
