Boot into Download Mode. You can do this by pressing and holding down the Volume Down and Power buttons. Ensure Odin recognizes your phone. Wait for a couple of minutes, after which your phone should reboot itself a couple of times.
Close Odin. Repeat the procedure from step 7. Disconnect your phone. Wifi, bluetooth, sync, no background apps, no live wallpaper, airplane mode, mobile data disabled, no widgets etc. And this is absolutely unacceptable for me and VERY annoying. Well, i can live with that. Actually I have noticed 2 problems: — it never goes in deep sleep; — checking the battery status from phone control panel I see that the battery is killed from the Samsung keyboard process!!
I have to kill it manually to stop this insane battery consumption. Every time I reboot the phone, the Samsung keyboard process starts again draining the battery. So I have to kill it every time.
Once this nasty process is shutted down, the phone works for up to 20 hours of normal usage: some phone calls, some internet browsing, some emails. The suggestion worked also for me! Glad to know it works for you. Once you get the ICS 4. Yes, this is normal.
Some apps may be not compatible with Galaxy Note, or there are some known problems with Galaxy Note. Some apps are geo-restricted, e. It simple, the service is not available in your region. I do quite a lot of cycling around Australia and use the MapMyFitness app for a variety of reasons. Now I can only get 4 hrs at best. Did you update to ICS 4. You may check and apply the update. Occasionally, the indicator may be not accurate. You can try to used your phone until it is shutdown by itself when the battery is so low.
Then charge it again to see whether there are any improvements. In some regions, this feature is NOT available, for unknown reasons. Hot or warm depending on ambient temperature is normal when you are actively using your Galaxy Note. As long as it can cool down when not in use, it should be ok. You Note should feel warm when it is charged.
But after it is fully charged, it should cool down if it is not being used. To be precise even when I switch OFF my note with no charger connected, it is showing as charging and then goes to normal and charging icon comes again. This problem was fixed when I removed the Battery and re-inserted it after 5 mins.
Again While following the former case that fixed the issue. The headache started when I connect the charger again. Charging happened as usual as it should be but when I removed the charger again it started to switch between the two modes. Also I factory resetted the phone. The odd thing is my battery life was good otherwise , it lasted two days in moderate use.
But if it gets into this Switching issue it drains in hours. Can this be fixed? I want to know the warranty period for the Note battery. Is it 6 months or 1 year? You may have your phone and battery checked in local Samsung service center. In Service Center they are saying like I have damaged the charging pin and that is why it is auto charging. But this is ridiculous, if that is the case then the same problem should have happened with another battery also. Can anyone tell me if it is a hardware issue or not.?
If so which part I need to tell them to check out. You may talk with them nicely and calmly , ask them how can you damage the charging pin. Ask them whether they can confirm the damage is caused by you, and the evidences. Please always calm, and speak slowly. These guys are also under pressure , and may be not happy with their jobs…. If they refuse to give your explanation, you may have to complain to local consumer protection organizations.
Hey ya guys! Here is that rom i used and tested and its amazing on battery life. Blessings to everybody! Some can be disabled, some cannot. It depends on your region and the carrier. Thank you very much. Thank u again. Can you please help in guiding — how to put widget for BetterBatteryStats app? I checked everything but its not showing on the screen. Hi i installed the BetterBatteryStats app yesterday , but there seems to be some problem in the same.
If you cannot set anything in the second deop-down, you can tap menu button left , choose More—Set Custom Ref. I have got a major problem with my Galaxy Note Unrooted device , its not working properly, driving mode is getting activated automatically and it is opening Voice talk option again and again, they charger is getting disconnected and also USB getting disconnected.
Occasionally, the accessibility may trigger it to start, so you may also check the accessibility settings. Anyway, if you cannot charge, you probably have to ask for a replacement.
It could caused by: 1. Hello, I have serious problem with my galaxy note. This normally happens when I open apps that would require Internet such as fb, after few minutes of launching it, phone will die. If I turn off data network, phone will stay on for more than 8hrs. Same thing will happen even if the signal strength is good. Btw, this has started after I updated it to its 4.
ICS 4. The two ICS 4. You may check whether the update is available for your region. You may also try to do factory reset settings—back up and reset to find out whether the problem is solved. Pleas back up your data before resetting. It sounds like a serious hardware problem.
My Note these days is giving a strange problem. The display goes off and it detects no key, neither there is any response by pressing the power button continuous press. If the phone is left for half an hour in the same state, it recovers after that and display and keys work fine. Is there a major issue? Do you recommend me visiting the samsung service centre for this? You need make sure you can show the problem to the guys in the service center when you visit there.
The developer options is not available in settings. Though I found Development inside Applications inside settings. Can you guide me so as how to do the setting in GB? It converts the electricity to heat and continues heating until unplugged. I used more than 10 different devices and this is my first experience.
All devices turn off when fully charged. If I leave it as it is, battery is drained completely in 1 — 2 hours. I hope this problem will be solved in Galaxy Note II or I will not purchase it in spite of my will to buy. For Galaxy Note, if it is connected to a wall charger, it will not enter deep sleep state even after the battery is fully charged the CPU will stay at MHz.
This is the reason you feel it is quite hot if the ambient temperature is not low. Some smartphone has an option to force the phone enter deep sleep mode once battery is fully charged, but none of the Galaxy phones have such an option. Battery drain usually has nothing to do with the charging.
You can install autorun manager to disable some apps that try to start automatically. If the screen is off, it is almost impossible to drain the battery within in hours in galaxy note. If you encounter this issue, you probably have to visit Samsung service center for a check or repair. I am stumped! It shows connected but I get battery low warning then the end.
I have replaced the phone 3 times thru warranty replacement and went to the latest software upgrade flashed in the repair center and still the same drain. Each time from a full charge. Any thoughts?? Probably, the charger does not have sufficient current. Although Navigation is the biggest battery drainer, a fully charged battery should last about hours without connecting to the charger.
As you changed the Note for 3 times already, you may try to change the charger this time to see whether there are any differences. Also, to save battery, you may also 1. My Note gets very hot during navigation with google Maps. After a 20 min trip, the temperature of the battery rises to degree C. The battery level drops very quickly. Is this normal? I am using ICS 4. Before 4. The battery would go down even when the Note was connected to the car charger.
I wonder if I should send my Note for repair? Yes, navigation usually drain battery quite fast, as mobile data, GPS, screen and the apps must run at the same time. So, it can be quite hot. But the battery drain should not be faster than charging.
You can save some battery by 1. I think 6 hours of intensive use consuming half of the battery is pretty normal! And CPU spy shows the device sleeps properly while not in use. By the way, my usual habit is to set the wallpaper completely black… that might further help to save battery.. I have two batteries on hand now with an external charger…. Checked with voltmeter the NO load voltage is now at 4. A full charge for the mAH battery coming with your Note should take about 3 hours.
Some third-party chargers may have higher current e. But you should not use such chargers so often, as it may be not good for the battery. To save battery, you can also set WiFi sleep policy. And for sync, you can choose what you really want to sync for each account. I am a new android user, and i was verry dissapointed because of this battery drain, and not going to deep sleep. Well, it had its advantages… i learned to root and rom my galaxy note just to solve this problem.
The problem reapeared when i installed all my apps so had to be one of them. I want to ask you webmaster or anyone who upgraded to 4. I charge it daily. Check emails manually times I did not auto syncing , and spend mins on replying emails on the note. Read some e-books for 1 or 2 hours. Talking time on this Note is less than 10 mins each day on this phone. I use automatic brightness. I guess in some countries, the price of Galaxy Note will decrease noticeably in the coming weeks once the Galaxy Note 2 is announced at the end of this month.
It is acceptable. If you need longer battery life, I think Motorola Razor Maxx can last more than 8 hours. It should be cheaper depending on locations. But the screen is only 4.
That is still quite expensive. Maybe because of local tax or marketing cost. As the Galaxy Note 2 will be announced not for order by the end of this month, usually the carrier drops the price first if carrier subsidizes phones; they usually get better price than retailers.
Hello everyone, recently after updating to ICS 4. Did you try to totally disable syncing? Sometimes, this can also be related to the exchange server settings as well. Some users mentioned some problems on Galaxy Notes with exchange servers since GB. You may also restrict background data settings—data usage , or disable background processes for apps settings—developer options—background process limit, set to none, this may affect some apps, but not the system to test whether there are any improvements.
Ok so the way to go about this seems to be limiting background processes to none, the datarestriction is not an option as exchange will not work at all unless you turn off the restriction and then after using exchange mail you have to turn the restriction back on again, so that is just not really an option if you have to use email on a daily basis.
I upgraded my Note to 4. Reboot of the phone and disabling the maps, social hub and DSMLawmo in my running apps solved everything.
It is too early to comment on battery back-up yet. Will monitor for today and post my observation. Alam Manger is core part of Android. Most of the time, the issue is caused by apps and widgets. So, for testing purpose, you may try to: 1. You only turn on the syncing you need. And the battery stay good for all day, even if i have to use 3g or wi-fi… but doing this all day is so boring. Very important, you need check whether your phone can enter deep sleep state.
If not, you then track the causes. Do only one thing to stop battery drain after ICS update 1. Usually, after full charged and disconnected from the charger, you can reset the timers on CPUSpy. Wait one ortwo hours, check the CPUSpy whether your phone can enter deep sleep state. If not, check the wakelocks and partial wakelocks. For Google map, if you are using latitude, you can logout to see whether there are any difference.
It is a kernel bug, so factory reset or formatting are NOT necessary. It has nothing to do with charging. Before you get the 4. It may come again later.. HI, Today only i got update for 4.
You can change the sleeping policy for WiFi. Also, you can manually disable WiFi once you finish using WiFi anyway, most people cannot remember. HI Thanks for the advice. I am seeing one thing..
For ICS 4. Probably, factory reset, formattig usb storage will NOT solve the issue. You need wait for ICS 4. Am monitoring the Deep Sleep mode for a while and if everything works normal for atleast a month then i will post the method in a blog. When i had this Battery drain issue this was the only post which helped me such a detailed study on battery usage Thanks to You! For most other causes, most of time, a reboot is sufficient. Also, when read the results, notice two important indicators: 1.
Did you listen music or use radio in these 3 hours? The partial wakelock is normal if you have continuous audio output.
If not, you can try to disable some sound settings, e. I mute all the dial tone or touchpad tone long time ago. This sounds normal, if you can play games for hours. If you want to make it longer, change the brightness. Pls help me to solve this issue, thanks! The battery life in Galaxy Note for continuous use is about hours only. Battery issue usually refers to having problems to enter deep sleep mode when the phone is not used. You may try to install CPUSpy to check whether your phone can enter deep sleep mode or not.
After ICS 4. If you want to save battery, you may 1. I upgraded to ics 4. Ive tried installing the 2 battery monitor programs and it seems to be normal.
Still the same problem… Any other fix for this?? You need check whether your phone can enter deep sleep state or not with CPUSpy. If not, check install BetterBatteryStats to find out the causes.
No reference on kernel wakelock since unplugged. The other metrics are all in the minutes unit. I factory reset my note and when i inserted a new sd card the problem is no longer occuring. Then after a day i try playing music via bluetooth headset paired to my note then the battery drains so fast and the the phone is very hot. The problem is intermittent. Im thinking it might be a battery issue..
But thanks to this thread i can hear some effective tips from pros like you guys before i change the battery. Did you check your mobile data? Bluetooth always drain battery fast. If you want to listen music for long time, use the wired one, which usually has better quality as well. Yup moblie data plan off. I always need to turn off the phone so that it will be able to charge….
Hello again. I changed the battery of my note and the battery is much stable now. Actually if i left it locked the battery almost not depleted at all. But all of asudden my note becomes warm without any major background processes running. I noticed everytime i charged my note its not reaching full charge. Im thinking it might be the charger but i dont know. Is there a thing like a bad charger delivering bad current to the notes system making it very warm in times?
When the phone is being charged, it should get warm, and your phone will not enter deep sleep mode. This will try to re-calibrate not very scientific the percentage. We have three options there and they Dynamic, Standard and movie.. Just recently i noticed that my phone battrey drained like in a few hours…. Is there any chance by which this problem can be solved. You need find out the possible causes by reading the output wakelock, partial wakelocak of the BetterBatteryStats.
Thanks for all the advice and help found here. Also to mention that permanent heat and excessive battery drain shortens the devices life time. Very disapointing, 4. Anyway, yes, it is quite annoying to remove battery and it may shorten the device life. Hope you will get the ICS 4. Eventually I recieved the 4. Battery drainage issue seems to be definitely gone now. Probably you will also get another minor update for 4. You may disable backup to Google servers: settings—Backup and reset, un-check Back up my data.
The reboot your phone. I love my new phone but battery problem is making me hate it. A few things you may check: 1. You are really a star to help us out here. Normally it should not affect your system. Just occasionally, some apps may complain. You only need change it back when you get problems with some apps. As per your suggetion i installed the CPU spy and found that my phone remains at the Mhz state for 8 hrs and never goes into the Deep Sleep mode.
The problem is easily encountered in ICS 4. Probably your update is 4. If reboot does not solve the problem, you can shut down your phone and remove the battery, wait a few seconds, then put the battery back and start the phone. This is a bug, so the problem may come again a few days later. Most of the time, a reboot should temporally solve the issue. Thanks Buddy! I just updated to 4. Hope the battery drain problem gets sorted with this update.
Will watch it for a couple of days and revert with my situation. Much appreciate your suggestions! My phone battery sucks even after getting the 4. Need to fix this asap.
My original problem of rapid battery drain is not resolved yet. Nothing alrming has come up in the Better Battery status app also. If it takes 15 hours to charge with the original charger, very likely, the charger is faulty, or the battery is faulty.
You can ask for a replacement. You may try other chargers. Molen Sponsored Links. In this article: 4g , android , android 4. Update: Samsung's press release is out, so check it out below!
