I decided to do an experiment this morning. My fiance and I both have Dincs. We're both running SkyRaider 2.0.1. We both have the 1500mah touch pro 2 battery. I bump charged both phones this morning and both went off the charger at 8:30. I cleared my battery stats in clockwork immediately after the bump charge. I didn't clear her battery stats. She had been getting better battery life largely because I use my phone a lot more than she does. That changed today.
The numbers don't lie...
---------------------------------------------------------------
my phone - battery bump charged and battery stats wiped:
8/3 - off charger: 8:30am
Stats @ 10AM
Uptime: 1.5 hours
Awake: 1.25 hours
% left: 94%
Stats @ 12:30PM
Uptime: 4 hours
Awake: 3.75 hours
% left: 85%
Stats @ 3:45PM
Uptime: 7.25 hours
Awake: 7 hours
% left: 68%
Stats @ 12:30AM
Uptime: 16 hours
Awake: 10.5 hours
% left: 24%
---------------------------------------------------------
Fiance's Phone - Bump Charged, battery stats not wiped:
8/3 - off charger: 8:30am
Stats @ 12:30PM
Uptime: 4 hours
Awake: 1.25 hours
% left: 68%
Stats @ 12:30AM
Uptime: 16 hours
Awake: 7 hours
% left: 12%
----------------------------------------------------------
I've come to the conclusion that wiping your battery stats is a very important thing to do and will give you hours more battery life. I'm currently losing a little over 4% per hour, which should give me 23-25 hours of battery life. This is a very significant improvement over the 14-16 hours that she will likely get.
I do find it really odd however that my Uptime and Awake Time are so close. This would normally lead me to believe that some program isn't letting my phone go to sleep, but my battery life indicates that isn't happening.
----------------------------------------------------------
Day 2: Didn't get rid of need to bump charge. First bump charge actually seemed to take a little longer this morning (over 30 minutes). Second bump was 6 minutes. Had to scrap today since my fiance's phone didn't charge last night. It wasn't plugged into the wall. Doh!
i might give this a try. i'll be interested to see if others try it and see what their results are.
Would I have to clear battery stats every day in order to achieve this additional battery life, or is it only a semi-regular thing?
???
How do you wipe them in clockwork?
Question- did you fully charge, wipe, then drain battery down /all the way/ before re-charging (e.g. phone shuts itself down) or did you charge, wipe, and then let it drain a bit and then just plug it back in the charger at night without letting it shut itself down from lack of battery?
Thanks.
I just tried this earlier as well. I bump charged (charged with power off until led went green, booted all the way up, and then powered off, repeated this cycle like 3 times) and then wiped battery stats in clockworkmod (it's in advanced).
Too soon to see if it makes a difference, and I really didn't have any problems but figured longer is better right
Edit: I now plan to let the phone run until it shuts its self off

I doubt it, but don't know for sure yet. I'm tempted to charge it back up now to see if there is a difference in length of time spent bump charging. I hope it shortens it. I won't be clearing either of our stats tomorrow to see if the battery gains comparable to hers stick.

I let it drain itself all the way, then charged it overnight. woke up. bump charged for 1 cycle then cleared the stats.
Doesn't work for me, bump charged this morning then booted to recovery and wiped battery stats. If anything, it appears my battery life is worse and one side effect is I did not have 3g on the first reboot.

Your 3g data drop on reboot has nothing to do with wiping your battery stats. It's a known bug in the 2.2 roms. There's also no way that it could make your battery life worse. You're probably just using more heavily today. It's hard to compare one day to the next since your usage levels vary. I know that I use my phone way more than my fiance and comparing the same phones pulled off the charger at the same time is the only way to tell if it makes a difference.

I didn't have any problems with 3g on the first boot, and my battery life doesn't really appear to have been effected. I can go about a day between charges, and it stayed the same.... completely anecdotal though and I've only been through one charge.
you should clear stats regardless

I know about the 3g bug but I've never encountered it, ever, until I wiped the battery stats. Maybe that's just a coincidence.
Maybe the reboot due to the loss of 3g is what drained the battery more quickly initially. My routine is the same every morning. Unplug the phone, turn on pandora, walk ten minutes to work. So I have a fairly even amount of usage for the first few hours since it sits idle after that.
Maybe I'll revise my initial thoughts to say it may not be worse for the battery but I'm definitely not seeing the improvements you are. Can I ask what ROM you're running?
First Time Bumping
I have had issues on and off since I got my Dinc. Running SkyRaider RC3 atm seems worse since I flashed it.... 2.5 seemed better. Doing a bump charge/wipe now and will post later with results. I am a fairly heavy user (I know 'heavy' is very relative) and know that a whole day (about 8am to 8pm) is pushing it for me, but I am lucky to make it till 12pm. I have actually seen it drop to 20% before 11am. During the first few hours of the day, I may check 2 emails, send no more than 3 txt and make one phone call... Seems like a big drain for that.
Weird, I wiped my battery stats today for the first time and also NEVER had a 3g problem when rebooting. Now EVERY TIME I reboot there isn't 3g untill I turn on and off airplane mode. I know the two doesn't seem to be revenant, but it seems like a lot of people are running into the same exact problem. Anyone care to input on this?
Well later on in the day I tried a restart again the the 3g turned on a few minutes after the phone booted. It still hadn't ever taken this long before, but it did come through on its own. Just a little update on my last post. I'm still interested in knowing why though
Well so far so good, but didn't use it much today. 3G bug happens to me every reboot, but comes on in a few seconds. I'm at 54% atm and bumped/cleared at 2pm est its now 10 pm

If your phone uptime is close or same as the number of hours u have since unplugged, that means it's the usb bug preventing your phone from going to sleep.
What u need to do each time your phone is fully charged (connected to the wall charger or USB cable), u will need to unplug the cable and do a manual reboot.
Otherwise, the phone might still think it is plugged to an external power source and refuse to go to sleep even while your screen is turned off and your phone is idle.
Then u should see using Spare Parts or Battery History App, that your uptime is around 10% to 16% of your total time the phone has been unplugged.
I have CM7.1 on my MT4G. Over the past week or so, my battery has been dying after 2-3 minutes of use. I'll get a full charge, take it off the charger, use any app(Angry Birds, Gtalk, text messaging...) and the phone will shut itself off after just a couple minutes of use. When I turn it back on, it says 2%-3%. It then shuts itself off again, I plug it in and turn it on...says anything from 3% to 90%.
I've always ran the battery down and charged to full. Is my battery kaput? Is there a way to fix this?

Most likely.. take out the battery and inspect for leaks(might be very small discharge you might not see it clearly leak can and will damage your phone)..let it die completely, and let it stay off, charge it till the green light comes on, reboot into recovery, clear battery stats, reboot and see how long it last, also change your brightness, and other settings that might be consuming battery use..if none of these helps.. just buy another battery.
Sounds like your battery is screwed. Just buy a oem battery or get a mugen power 1650mAh

My issues aren't quite that bad, but after I upgraded to CM7.1 from 7.0, by battery has been terrible. 15-20m of phone calls over BT takes ~20% of the battery. 15m on Angry Birds chewed up ~40% of the battery. I downloaded the latest nightly (252) and will see what happens.
Try a dif battery and see if it does the same thing. So you can rule things out

Mines also been horrible since I went from CM 7.0 to CM 7.1. Not sure whats up but it dies in like 6 hours on standby. the battery use app shows that most of the battery usage is by "Cell Standby". So effectively, doing 'nothing' is eating up the battery?
~Phil
I guess I'm not having the problem you guys are having with battery drain. Granted I didnt use my phone that heavily, but still sitting at 60% after 10 hours. But if your battery is dead after 3 minutes something is seriously wrong, I agree and try a new battery.

You need to calibrate the battery after changing ROM's. Download a battery calibrator from the market. (Don't pay for one. There are like 10 free ones)
Charge the phone fully overnight. Calibrate it in the morning.
Give it a few days to gather new battery data, and then enjoy getting a full day's use from the phone.
Update
So, it's gonna have to be the battery. Recalibrated, no good. Tried a few different ROMs from CM7 nightlies to MIUI, no good.
Waiting for the new battery to get here to be sure.
Thanks for all of the help and advice!
same problem here
hello there, i got 2 mytouch 4g both running the same rom (virtuous unity 2.39) one of them has eaten 2 batteries that i bought thinking that the batteries were somehow broken or damaged... i came across this thread, read the reply recomending battery calibrator when i reached for my phone (that i left sitting on my drawer waiting for a new batt AGAIN) to give it a try and to my surprise it was still on and i has been on for 2 days 11hours and the fricking battery was at 97% before that it started to turn off-discharge so i put the thing on airplane mode and there it was till now... dunno why or what but i think it has something to do with the radio/network... hope we find a cure for this
I've been having this same issue, and I was wondering if replacing the battery fixed the issue? Thanks.
When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I don´t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.
Is anyone experiencing weird issues with battery before recharging? i had 2 days phone on batt and 3hrs screen on. It was at 53 % before i decided to charge. I fully charged it and now im losing 10% every hour even with phone on idle. Its weird cause every other charge will last a long time.

Yeah, I'm still stock on this phone and I'm getting inconsistent battery life. I usually charge every night, so I'm running about 16-17 hours per day. Almost identical usage each day but one day I'll plug in with 45-50% remaining and the next it will be dead when i plug in. Very odd. I'm going to root this thing just so I can get rid of the bloat apps. Well, that may not be the only reason I root. I may be compelled to put some AOSP on this and see how it rocks it.
well i don`t really recommend to ROOT stock rom, it caused for me a battery drain ! also KitKat known for drain issue even on Pure android on Nexus 5. I don`t really know a fix but i`d give u some tip and it might help
1. Re-flash D80020c
2. After re-flash do a factory reset
3. Don`t root or mod your OS
4. Turn off Sync or Location Service (or set to battery saver mode)
i did those steps and i have 34 hour on battery:
3 Hour screen on time (and about 30-40 min gaming in this 3 hour)
Left about 49%
i hope i helped a little
Potential solutions:
Have a look in Settings > General > Battery and see what seems to be using the most power. You could have a problem app that’s using GPS or trying to update frequently. If you can identify the culprit then you can remove it.
There’s a slim chance you have a faulty handset. If adjusting your usage and tweaking settings doesn’t’ result in any improvement then take your LG G2 back to the retailer or carrier and get a replacement.

I always have location turned off with all bloatware rwmoved. I honestly think you have to drain it to about 20% then charge. Cause i never have problems when i do that. Gonna try and drain it out again and recharge and see what happens then.

Its kitkat,it says rooted d80020c in my signature. Well here is my latest results. Left it on overnight and was at 53% with data off. Checked it this morning and everything was back to normal again no battery drain or low estimated battery times.weird cause i charged it around this percentage. I think you have to take it down to at least 20 before charging will find out later today when i charge.

well i really not heard about Deep sleep drain but while idle it`s drains bit faster then JB, with jb i could get max 40 hour and about 6hr screen on time and + 10-15% battery while on KK i can get 42 hour but about 5 hr and 45 min screen on time with 0% battery it`s seems a bit problem for 4.4.2 i think Google will fix it and hopefull we`ll get new update from AT&T if this prob will fixed
P.S i saw that if battery at 100%, overnight it won`t fall to 99 but while battery is on below 100% it drains about 1-2 % overnight is that a known prob?

2% overnight is pretty good, given that it's on WIFI I'm assuming?
I lost 25% overnight last night when I was off WIFI, so I factory resetted mine.
Took it down to 20% and discharged and its fine. Im guessing its a bug,but, easy fix just take the battery down to 20% or lower before charging
Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!
Common problem.

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!
Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.
Thank you for your response!

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

Thank you very much! I will reply with updates soon!
I had a similar problems, and I have received my new battery yesterday which has been charged in 51% so I drained it to 1%-0% without unexpected shutting downs, I have charged it again and so far it seems to be ok

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
