I have had battery problems plague me for the last month, regardless of flashing, reverting to stock etc.
The following data is compared to my friends captivate, who is running the same setup as I am Continuum 3.11 and Speedmod k13c. He currently gets at least 24 hours on a full charge (thats WITH gaming and calls etc.). I can barely scrape 10 on minimum use.
At first I thought it was a rogue app that was constantly draining, but unfortunately it was not (after several trials and monitoring apps).
Next, i tried reflashing, Master clearing + flash from stock, flash at 100% charge, but still nothing.
Next thing I tried was to see if it was my battery was faulty (doubted it because it was new from original phone. Only had it for 2 months) by swapping batteries with my friends Captivate (also original battery). I concluded that this was not the problem since he was getting great battery life (if not better since mine is newer) and I was still draining.
After, I tried battery stats wiping, recalibration (bump charging) flash to stock and flash to a rom with reportedly good battery, with k13C speedmod. Still bad results.
So heres my current situation: I am running Continuum 3.11 with speedmod k13c. I have tried almost everything in my arsenal and googling but I have come back empty handed. It is NOT the battery, rogue app draining OR rom/kernal. I am completely stumped.
Heres a summary/extra details of my trials:
-Flash to stock and try again
-change batteries
-wipe stats, drain and recharge, charge for 8 hours, bump charge (recalibration), flash from 100%, master clearing etc.
- setting brightness to lowest, wifi off, plane mode when turning back on
- being anal and not installing new apps / using what rom came with
- My phone remains ice cold on standby. I know that when it gets hot, it drains (during standby and etc. but this time its ice cold)
- Here is some data: In one hour of minimal use (checking texts, replying etc.) I lose 10%. overnight I lose around 20%. In a heavy usage, 4 hours.
(note : I know that some of you might consider that barely passable battery life, but if I directly compare to the set up of my friend, its not right since in heavy usage he gets about 12 hours, which is my max per charge on minimal use)
Im hoping someone can help me with this problem, because I believe that this problem is plaguing other peoples phones as well, not just mine.
REFERENCE THREADS THAT I HAVE LOOKED AT:
This one
And this one of course
EDIT:
I recently swapped batteries again with my friend, because I recall fixing it at one point, but I had to reflash it due to a bug or something, i dont remember. But when we swapped batteries and swapped back, I seem to have fixed it. This leads me to believe that My phone right now has no idea where 100% actually is and its only charging to some random % that is NOT 100% .
This time, I swapped with him when he had 47 percent, and I had 87. After we swapped, we immediately checked the percentages. To my surprise, his 47% on my phone immediately turned to 23% But strangely, that 23% remained (the charge on 23 seemed to be holding for quite a while). But when I recharge, it charges WAY too fast (10 minutes of charging = 40% in total from 23%? B.S.!!!)

I guess thats happen when you flash new rom or kernel or modem...you need to wipe battery stats to fix that....

I wish it were that simple =( I already tried that via recovery. Unless the recovery method is bugged and not actually wiping the stats. I will manually delete the battery stats and retry, but I dont think it will work.
im just reporting back that manual battery stats wipe did not work =( Any help please? I am absolutely stumped
sorry to triple post but I thought I should ask something else:
Would extracting the batterystats.bin from another captivate and using that one work? (assuming i set permissions correctly)
Hi all,
Few days ago i've received a new battery for my nexus.
I'm not sure now it was a good idea, but i've reset battery stats (by recovery) and proceed to a bump charge, then reset stats again.
I've done it twice because the first time, charge process jump from 55% to 22% and was stuck at this value. (bump charge and reset)
Now, my battery life is quite good (around 20 hours) but battery indicator is crazy.
Just after being unpluged, its drains quickly to 27%, stuck at this value for a while, then drains again to 2% and do the same.
What can be done ?
Wipe and reinstall cm ?
Thanks !
wrong thread to post to mate...
but anyways try reinstalling ROM and using battery calibrator to calibrate battery if your new battery allows it...
i bought my galaxy note 3 days back. except for battery issue , everything else is fine.
problem - charging drops below 85% from 100% immediately after unplugging. this happened yesterday and also today....i charged the phone while sleeping ( 1 am to 8 am ).....charging dropped from 79% to 100% imediately after unplugging....
i could use some advice about correct charging methods - can i charge the phone when battery is 50% drained or should i wait for the battery to completely drain??
with lithium based batteries you definitely do not need to completely drain the battery before you recharge it.
As I understand it there are two possible explanations here:
1) Your battery is broken. If nothing in 2) helps, get a replacement battery.
2) Your battery stats have gotten screwed up somehow.
Depending on what version of android you're on this can be fixed by either:
a) doing nothing for a few days and seeing if the stats start behaving normally. I would recommend you start with this.
b) wiping your battery stats. There are a bunch of apps that can do this, or you can do it from CWM.
If you do wipe your battery stats, your phone will probably report weird battery usage for a couple of days. See a).
Hope this helps.
Using ROCKET ROM reloaded
I've got very good battery life when not using phone - 3g/wifi and draing at less than 2% an hour and will last over 2 days on stand-by. If I do anything that involves having the screen on though then the battery can be flat in not much more than an hour. If i try and examine whats draining battery I can't get past screen time/android as culprits.
I have factory reset and reinstalled ROM twice to check. Phone is 12 months old - Is it likely just in need of a new battery?

yes try a new battery first as it is old.
Hello everyone, here is my problem with my Note 5 SM-N920W8. Since the last firmware update, n920w8vlu4bpj1, I have been having extreme battery drain in sleep mode. Going from 100 to 60-65% of battery 6 hours after. I have been reflashing with smart switch the firmware, did a factory reset, wipe cache and wipe data. Name it, I think I did it. I don't want 3rd party app, they are only band-aid. Could I try to downgrade to my former 6.0.1 firmware, n920w8vlu2bpe3 version wich I had excellent experience with and excellent battery life, loosing about 7% in 6 hours on sleep? Battery use is mostly Android OS for the battery drain. Thanks in advance for any advice
