again .. galaxy note battery

This is my first post here. Am kinda new to the forum
Well, i know this issue have been said over and over. But i didn't get anything out of other threads
I have my new gnote on stock ICS for 6 weeks now. It's battery drain rate was about 1 % every 5 minutes on browsing. Then one day i installed game "angry gran 2" from 1mobile market, because it said on playstore not available for ur country. And since that moment the battery went crazy. Drain 1 % every 2 or 3 minutes. I uninstalled it a day later and the problem is still there. This was about 10 days ago
I checked running apps nothing is different than normal
I dunt use face book app
I uninstalled samsung push service
GPS and location services are always off
The mobile goes into deep sleep very well no problem with that acc to CPU spy. The processor which usually works is 200 mhz then sometomes 1200 mhz
All settings since the day i bought it are set to save energy "lowest brightness, sync is off .... Etc."
Now the battery does not work notmally unless every charge i remove the battery for few minutes and put it back' i did this today before i turn off my phone battery was 92 % remived battery put it back and it's 87% ! :S
Yester day about twice after going to sleep i find batter increased 1%
Can you help me please to spot where the problem is ?
I have better battery stats but i dunt understand it
And one more question please, does having large number of apps even if not running in the background cause battery drain ?
Thanks all will greatly appreciate any help

+1 on that. My note's battery runs really fast and I'm not even using it for hardcore gaming. The battery gets really hot at times too.

update: screen shot from better battery stats
Check these screenshots from better battery stats is this rate normal ?

Hi! Once I had a similar battery issue, but in my case it was after flashing a custom rom. Battery started draining much faster than usual. And sometimes battery percentage jumped up too. Have you tried to remove/insert battery, then fully charge your phone and when fully charged run "Battery Calibration" app from Play Store? Have a feeling it's not the solution for your battery issue, maybe a long shot, but still maybe worth a try if you haven't done that already?

Well i haven't tried battery calibration yet. Will try it what to lose !
I searched for it it needs rooted device. Do you know some app does not need root ?

There's no such thing as battery calibration apps, it's a con, you just put them through a few cycles and they're fully charged, modifying the battery stats does nothing for the use of the physical battery.

That is correct. The name of the app might be misleading. It does not do anything to the battery's physical condition at all.
The problem I had was that my "battery" suddenly started to drain very fast according to the battery icon in status bar. It dropped about 1%/min during screen off, and even faster with screen on. I charged my phone to 100% about 6 or 7 times. But as soon as I unplugged the cable I had that very quick drain. I guess the battery itself had much more capacity left than shown, it is in good condition... but that didn't help me because my note turned off when the battery icon showed it was low on % and I had to start charging again. Then I ran this app, which only thing it does is to simply delete batterystats.bin file if I understand it correctly. I don't know much about these stuff, but after that the usage time of my phone is back to normal again

I just had a look at Play Store and all the apps I saw that does remove batterystats seem to need root. Probably it is a system file you can't touch without root access then Also, the battery issue you have might be caused by something else.

Well i wish it can be solved this way ... Coz other option am.gonna take is downgrading to GB then factory reset as i understood this won't brick my phone if I got it carrectly
May be it's calibration thing ... Check the attatched photo the batteru since 3 a.m. To 9 a.m. Is almost at same level or increasing .. Maybe it's some kinda of system calibratoon of battery indicator against battery fast drain while working .. I dunt know

In system settings > battery: what is reported there?
Have you tried boot in "safe mode" to see if it still drain the same way? It will exclude most of user installed stuff as your downloaded apps and such from running.
But remember you might loose some user settings on your phone when booting normal again after safe mode.

although battery calibration app does nothing to do the battery hardware, but it does calibrate on how the battery percentage is being read by your phone. It wiped your battery status, allowing 100% charged to be read as 100% charged. sometimes, due to various reason (ie. flashing without fully charging), your battery status will be inaccurately read by your phone. For example, you charge your phone upto 2000, havent completely charged to the max capacity (2500) but the phone already read 2000 as 100%. and because of this, it will look like your battery drain really fast or the percentage jumping up and down. i guess.
wiping battery status requires you to have root access. thus, this app will only work when you have rooted your phone.
it is true that after a few cycles (not sure how many times) of charging the battery status may go back normal but hey, if we can make sure to do this calibration with only one cycle, why we have to do more?

My battery is crazy. Yep in deep sleep some times it increase 1 % .... On the other hand while working with the phone it drains very rabidly at a rate 3-3.5 % per minute .... Either on wifi or not ... It's normal rate used to be 5 % per minute till the day iinstalled that game and the problem persists even after i removed it
As for the explanation in the thread ptovided it does not make sense to me .. Because every time the battery jumps up the battery drain becomes soooooo rapid afterwards

I was trying to find a way to root my phone but i can't find any data on the web ! For some reason that way of rooting tgat was on xda deleted ...
But I have a question ... I always wait rill my phone completely empty and charge it till completely full ... I leave it in the plug about an hour till the complete sign shows in notification bar
Does this mean that way that my battery is already calibrated and i shouldn't try to bother to root the phone and get the app ?

There's Dr ketans thread on rooting in the stickies of development section, it's very simple.
After 1 or two full charge cycles, the battery will recalibrate itself, no need for any app, they don't do anything anyway.

I tried safe mode .. And yeah performance is a little better though still not like before .. it bought me an extra minute per 1% drain .. So i dunt know what that says ? I checked running processes the only difference that facebook and avast antivirus dunt run in safe mode .. Which were probably always there since i got the phone nothing new..

Hello everyone, need some advice. I am unable to know if my battery is functioning normal or should i get it replaced. Please see the atached picture. You will see that my battery draining off within 4hrs with 2G data on. It has been happening from past 2 weeks. Just want to know if it is normal on 2G. Or should i get my battery replaced with a new one. I have read somewhere that with 2G battery of Galaxy Note lasts for about 6 to 7 hrs. Mine goes for just 4 hrs max.
Few details about my usage:
1. Data sync is not on all the time. But for every half an hour i keep data sync on for 30 for 40 seconds max to retrive mails.
2. I dont not watch any videos, online or on mobile.
3. I dont play games at all though i have around 20 games bcoz of this poor battery life.
4. I do not do video calling.
5. With the above usage and little bit of online videos using wifi, I get around 3 to 4 hrs of battery life.

[Q] Battery dying super fast after root, please help!

Ok, first, I looked around and tried stuff like battery calibration etc. but no luck, here's what happened:
I got my galaxy ace and rooted it with CF-ROOT, flashed it using the recovery menu that stock already had.
Phone was ok for 1 week, then it started sucking battery like crazy (also charges too fast), 100% lasts something like 5mins...
(at this point it was still stock with rooted kernel)
Flashed a CM ICS ROM from the forum => same results with battery
Went back to stock, no root anymore => battery still the same
Does anyone know how to solve this? Thanks in advance!

Why didn't you use the normal .zip that just adds super user? Maybe we have the same type of Ace that is completely incompatible with flashed kernels. Brings battery problems. Only kernels you can use are the ones that come with the rom you installed.
Reflash stock rom and root using any other .zip around the forums.

Because you said you charge it too fast. Try to charge it for 3 hrs. If u see 100 % that doesn't mean that it is fully charged already

Do this, full use your battery till it totally gets dry and charge it to 100% without break..note that your phone should switch off conditon while charging to 100%..

What do you mean by normal zip? As I said, I flashed stock back, no more rooted kernel, but it's still draining battery, shouldn't it have gone back to normal with stock? Should I root again with this normal zip to be able to solve the problem?

Maybe your battery is "gone" (I mean cannot charge anymore). If you can try your phone with another battery borrowed from a friend or buy a new one cheap to be sure the problem is the battery and not the phone. The last option for me is to buy a new original battery a give a try. If you have a method to test the battery out of the phone is best. Good luck
Inviato dal mio GT-S5830

Do 1 thing. Recharge for a long time till 100% . Choose a stock based rom like sgs2 v10. Do full wipes, delete battery stats.bin, Format data,cache, system, sd-ext ( if any ) & flash rom. Reboot & try battery. If it's still the same, go get a new battery..

hey, try this app called nova battery tester. It will tell you a lot about your battery's condition.
You can find it on the play store.
Also check whether your phone is entering deep sleep.

I tried that, the friend's battery on my phone had the same behaviour, and my battery on friend's phone worked fine... so it can't be the battery
Why the hell it won't just work normal if I flashed stock back?

Tried recharging for long time, no luck, also tried many "battery calibration" apps also with no result.
I'm guessing buying a new battery won't solve anything either given the results with the friend's battery

Have you checked your CPU behavior ? Which states it is in, etc

1. Un-root then root again using the normal method which just adds SU.
2. Try charging for 2-3 hours. Sometimes it displays 100% though the battery level might be as low as 15%
3. Do you do over-night charging/ charge for very long durations/ play lots of games during charging? In that case your battery is over-charged. Check it. It should be puffed up a bit. If this is the case then, sorry mate, but you'll just have to get a new battery. And don't ignore this problem. Trust me, as bad as it is, it's all downhill from here.

[Solution] Flickering screen, poor battery backup, sudden discharge [n7000, Note]

A month or so back I started facing weird problems with my year old Galaxy Note, n7000:
1. After reboot, the battery would go down by 15-20% and then without charging the battery %age would gradually increase by 5-10%
2. lots of flickering on screen followed by auto shutdown whenever the battery %age went below 15-20% after normal usage
3. Very poor battery backup (I blamed most of this to the Rom Mods I had been installing at that time- only partially correct!)
I am sure that many of you might have been facing such problems and running from forum to forum to get a solution- I did.
Solution:
Get your battery replaced- most of us have had our Note for a year and some months now...life of the battery is approx 1 year for regular use, thus, the stock battery that we got with our Note is well past....
I never faced the above problems after battery replacement!
Hope this helps others like me!!

I started having this problem after getting a new battery, my old battery which was weak never showed flickering. But this new one which is original samsungs battery at below 15% show flickering and sudden discharge despite a good battery time.

I got rid of the damn problem after getting new ones...Is it possible that the batteries you bought are not genuine/fake?
Which ROM are you on- the Stock one or some mod-rom?
When I was searching for a solution to my battery issues some members suggested battery-calibration and full charge-full discharge cycle to get rid of the problem. Both the solutions suggested at that time did not work for me.
There was also a solution about cleaning the mini-USB connector which gets seriously dirty collecting grime from our pant pockets! That did work for me initially when the battery was good.
Please let me know if any of the above helps you.

Guys - Me too have the same issue, but this started immediate after updating the Jelly Bean 4.1.2. It never happened while on official ICS.
I could observe the battery is very much thick now, which is a symptom of over charging. The screen flickers and brings phone down abnormally.
After connecting the charger for a 5 seconds, suddenly the battery level shoots to original state from where it went down. Most frustrating, it happens very frequently.
I am not sure if the same will persist even after replacing with a new battery. Or I would need to go back to ICS again.
Any suggestions?
Cheers!

If the battery is bloated then it's better to get a new one.

Erm... is this thread still up?
I just wanted to know if the bloated battery would cause boot issues, stuck on the model screen?
I would guess the problem is with the bloated battery's voltage is insufficient to power up the systems... i guess
I need confirmations... thank you in advance

That never happened to me with a bad battery. What version of Android are you running?

i changed my battery just a two weeks before and the battery backup has decreased very much
can someone help me how to check whether my battery is in good shape or not ?

What do you mean with "battery backup"? Maybe "capacity"?
What battery did you buy?

4.1.2 xxlsz deodexed by eybee
The problem is, after I restored most of my data, apps and system data separately, the screen flickers a little bit and then the restore process completed without any problem. After that I restart the phone, stuck at the model screen only for unknown reason. The data is also from previous xxlsz which I had trouble with some system app crashed but fixed by returning to another backup though.
So, currently I'm leaving the phone without any data restored, only stock fresh out of the box xxlsz with titanium backup only installed. So far the phone is quite stable, I've turned off the adaptive power adjustment in display as well as lowest brightness just in cast it might occur again.
I've been reflashing xxlsz a lot this morning, over 3-5 times due to stuck in boot logo and model screen. Even though flashed the latest philz 4.90.8, it would just revert back to the old philz 4.8x with cwm 6.0.2.8
One last thing, my batter bloated pretty bad about half of it has been expanded. I mean from the bottom part (no copper connections), half of it has reached out of the body.

Well,
hppend to me b4, flickering issue below 10%. It was bloated. Bought new one. Bloated again after 6months. Again, bought a new one and it can last only 7 hrs without switch on data.
This is what we get from massive production company.

I seem to have the same issue
1. Battery drains rather bad
2. Screen flickering
3. Auto shutdowm
Used the battery in my wifes n7000 , however no issues at all
Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD

@amogh you can check your battery voltages and battery temperature and compare that to optimum values. you can also use apps like AnTuTu battery tester.

Flashing another rom again wont solve much of the problem, if you happens to have the phone stuck in around bootloop and able to go into cwm, brace yourself, this process can get very repetitive to solve because a mere battery able to do such a problem. I had these experience before about 2 months ago before buying a new battery. Hope this link helps you understand a bit more of the battery

Z1 Battery Problems

Hi, I have a Sony Xperia Z1 running cm12 nightlies. I've been getting this problem where the phone shows 40% battery but turns off at this and on restart shows 1%
This was okay, however, recently it has started turning off at 70%
I don't really want to replace the battery, as my warrenty is voided (isn't it) and it's not the easiest thing to disassemble.
Thanks.

Can you try to calibrate your battery once?
100-0% and then 0-100% in one go

Don't waste your time on flashing and calibrating. You have classic symptoms of a dying battery. Soon, the phone would shut down at 90%, because your battery capacity is 6-7 times less. Try to run a youtube video and your phone will die in less than 20 min.
If you read this and general threads, you would have found similar complains. You need to replace your battery.

Ugh yeah that's what a quick Google search told me as well
How easy would you say taking apart and replacing the battery in a Z1 is?
Edit: If it's the battery why does it suddenly cut off instead of quickly decreasing.

Because battery is measured by voltage and when voltage goes down to a certain level, kernel shuts down the phone. If your normal battery has 20 cells, yours has only 3 left and voltage goes down rapidly under load, because the other cells are dead. Even if the battery has 1 cell left, when it is charged, the phone will show 100%, while there is a real capacity to hold just a few percents.
Watch youtube videos on how to change the battery. You may or may not break the back pannel (I did). So, get a replacement back glass too.

I had same issue with my z1 since last 4-5 weeks. Thinking that battery is dying I changed it yesterday with a brand new sony battery. Now even after changing my battery, the problem persists. Phone switches off suddenly with 45-60% charge left.
I am on PAC Roam running 5.1.1 . Prior to this I have tried MX rom, Ressurection remix and few other ROMs running 5.1.1 however the same problem wa there as well.
I think it is not only to do with battery but with something else. Please help

You probably have a random reboot issue (thanks to some recent dumb kernel/rom improvements), as opposed to switch off. Look for what your battery shows after reboot: if it is 1%, it is battery related and you got a bad replacement. If it is close to the value before reboot, it is your rom/kernel. There is no third option. And by the way, battery drain has nothing to do with bad battery. Most drains are caused by Gapps and social apps. Also, if you install a new rom or battery, you have to give it a few charging cycles.

Sometimes (like just 10 mins back) my phone goes off and when I reboot it, it comeback with same battery percentage but most times it needs charging to reboot and when it comes back alive, battery stat is 1%
Same was the case with my last battery. Now I am even more confused as to what is the exact cause Should I lock my bootloader and flash Stock 5.1.1. ftf and see if problem still persists?

If your phone boots on its own after switching off, then it is not the battery issue. CM roms are becoming worse and worse for several reasons: too many devices; bad sources from google and incompetent software guys (both at CM and Google). I don't like apple and their products, but when one entity controls hardware and software, you will have fewer bugs. Google pays their engineers for introducing more and more ad related things into Android, as opposed to making Android a full blown operating system.
Go to stock and see how long your new battery lasts: if it dies after 20 min of youtube, you have a bad battery. Period. If it is not, then find a custom rom that does not have random reboots, which unfortunately there is only 2 or 3...
For any measurements to be valid, you need to give your battery at least one cycle on a current rom (from 100% to 15-16%).
P.S. You may have both issues. If you paid $10-12 for a new battery, then most likely, you have a Chinese fake that only looks like real Sony...

I bought it in Rs 1500 (approx $30) from authorized sony service centre which also gave me a warranty of 6 months. Worst case I can return it to them but just want to be sure before I try and do that.
My phone switched on once after going off and it was with same battery stat (last instance). there have been couple of times when I could turn my phone on but it showed only 1 or 2% battery.

Just do what I recommended in the previous post: go to stock, fully charge and see how long the battery lasts on youtube: in 20 minutes, you should lose no more than 13-15% on a new battery, as opposed to go to zero. Some Z1 batteries have a problem: Mine died about 9 months ago. My old Xperia ION (which is a 2012 phone) battery is still going strong (lasts for at least 2 days on Jeallybean).

I just recharge it to 100% and ran YouTube for 35 mins and from 100 it went to 93%..!!
Only 7 battery loss for 30mins YouTube on 240p and full volume
I hope the issue was there for first few cycles. In case if still persists, will try and flash FTF tomorrow and see what happens:fingers-crossed:

That means your battery is fine and you have random reboots related to the rom you use. Here are custom roms that have no reboots: slimrom; tesla, DU and Jaguar. The last 3 are mine. LOL. I am not promoting my roms, don't need to (just look at the number of downloads, especially Jaguar)... In case of Jaguar, you have to flash November 1 kernel on top of the latest release. It is in November that they introduced changes that cause reboots...

Haha..
I know you don't have to plug-in your roms. I guess I will hold it for a day to see how my phone behaves. Major battery drain is when I play Clash of Clans. I am on CoC to check endurance. If not, them will move to Jaguar with Nov kernel on top.
I have realized that it's somewhere in November since there random reboots and battery issues started

I flashed latest Jaguar with Nov 1 kernel and c6902 modem (Version 4). Have also flashed 5.1 gapps (Micro version) and restored all my apps. have created Zip from titanium backup.
Phone still went off from around 75% battery. when restarted again, it came back with 45% battery, just to die within 30 seconds :crying:

pathetic battery

I am on Repulsa rom with mad max kernel. And the battery life is pathetic. From 100 to 20% there is no problem but as soon the battery goes below 20% it will literally go to zero in 10 sec and will shut down. It happens 9/10 times.. As soon as it goes below 20% it will shut down in few seconds.. This is not rom or kernel issue because this has happened with different rom and Kernel too.. If anyone can help it would be of great help..

I dont have that much knowledge but i am unrooted and happened to me serveral times as my battery shut downs in 13 percents. I looked for a solution and my issue resolved. Hope if it can help you
Maybe its calibration issue
Maybe your phone thinks 20% is 0
Try using fully discharge your battery until it shutsdown then go to recovery mode and waste the juice until it turn off and dont even boot into recovery. Then charge full with power off and again discharge to 0. Again to 100 and see if problem solves.
If not then maybe issue is with battery

I'm getting 5-7 hours here depending on the usage but to be sure go back to stock room for 5 days and check the SOT BY THE WAY I'm on Lightrom with the mad Max kernel

My phone used to be like this... so annoyed.
I tried everything but no result: using battery calibrate apps or methods, flashing stock rom, reinstalling TWRP,...
I am quite sure when your phone is at 20%-, you can't see battery % in TWRP mode :V.
I think the cause is TWRP ( data can't mount )
Here is what HAPPENED to my phone )
I flashed ECHO rom and my phone got bootloop..."Only official binaries ...."
Fine....too easy to fix... I flashed my stock rom and ta da... My phone's battery was Fixed :V
So ...you can consider bootloop your phone to fix the problem ))) Then wait 7 days without restarting your phone... reinstall TWRP ( "NOUGAT" or "OREO" ). And when you download dm-ver... zip to install TWRP, look carefully for LATEST version "LATEST". And dont update your TWRP or use themes for TWRP (Old is gold, simple is perfection :v , fuctional is too enough)
GOOD LUCK

Why wait 7 days with no reboot? Not needed if it's to make the OEM toggle visible...just wait 7 days or use the date-change workaround. Reboots affect the uptime timer but not the server-side OEM unlock timer.

Happened to me lately on stock, never rooted. Try turning off quick charge and use normal method instead for a few cycles. Maybe test on stock firmware just to be safe. If no improvement it might be a degrading battery.

I am thinking to factory reset the phone to see if the problem is solved.. N try the solutions offered ie calibration, quick charge off

Sounds good, just be careful with calibration...fully charging or discharging the battery reduces it's overall lifespan. Don't do it too often.

I did factory reset including internal storage wipe and calibration Bt still the problem exists.. Now the battery will go down to 15 then directly 14,12,10,5 in seconds even if I connect charger at 15 it will go down till 3%..

Yeah, it can be possible to degrade the battery that quickly.
It usually happens when you let your phone go under 20% frequently or let it die completely before charging it again.
I usually do the lowest 25-30% and the 80+% charge daily, then finally use it all the way to 20% before going to sleep, put it on a slow charger, and by next morning its at 100% without keeping it charged 100% all night (which can also degrade the battery, just a lot slower than discharging it completely.)

I have had my phone a week before it came out and my battery is awesome. It lasts me all day everyday. Best phone I have ever had.
