No point in wiping battery stats. - Nexus S General

It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

Those apps just delete data/system/batterystats.bin file, which, accordingly to +Dianne Hackborn: "has no impact on the current battery level shown to you" and "has no impact on your battery life"

Yup, I did after reading her post. All the battery stats are used for is to show which apps have been using your battery under Battery Usage.

That's a nice find. So all these while it was just a placebo :|

I laugh at everyone who used all these things and said it worked lol. I never had any luck erasing or using any battery calibration app so I figured it made no difference and when this article hit a few days ago it just confirmed it for me

so..
when i rebooted manually yesterday with 8% battery left and booted up with 53% battery, you want me to believe that theres no reason to delete my batterystats.bin? well i deleted it and rebooted again, booted up at 8%. in a perfect world there might not be any reasons, but ever since my first android(g1 oct 2008) and every android device ive owned since, the batterystats.bin file has always lost accuracy with a short amount of time. and it seems that deleting the file and rebooting has been the only thing to make it accurate again.

keep an eye on your battery levels the next few times you reboot or flash something. and check out this thread from today, the op has an issue, sound familiar? http://forum.xda-developers.com/showthread.php?t=1449470

How many times have reps for companies given incorrect information? In the asus transformer prime forum there is a thread where an Asus customer service person said ics wasn't released for the prime, yet everyone is getting the ota for it.

I'm of the "I've owned more than 1 android phone and a battery calibration has never done anything" persuasion. It just never has. Users who get great battery life either have great signals or don't use their phone. Owning multiple chargers/batteries is the best way to ensure your phone has juice.

I agree. I don't think anyone states it actually "improves" battery life, it just helps ur phone be as accurate as possible so you don't has inconsistent battery levels. There's no way any fellow flash addicts have not experienced battery level inconsistencies after flashing roms. It happens to me all the time
Take at look at the steep drop in the graph. I'm pretty sure wiping battery stats is purely meant to correct that issue as opposed to actually increasing battery life

As she noted, the battery stats file has NOTHING to do with your battery level or percentage. Now, its possible that you're right and she's wrong but I tend to believe the person that has actually helped DEVELOP Android versus personal anecdotes and intuitions.

It is not a rep...it is a real engineer at Google Android, never saw the google+ link?

yep, quite believe it...never....ever wiped stats.
Fully charging the phone - firstly powered on, then off a few times, sorts the calibration.
And no...you don't damage the battery by fully charging powered on and off - they've made these batteries more intelligent than their gullible owners.

Show us your battery life!

It seems as though battery life is one of the most common topics among us vibrant owners. We are always looking to increase battery life, whether it be with a new rom, new kernels, or apps from the market. I wanted to start this thread for everyone to share their experiences, tricks of the trade, etc on getting the best battery life.
Post pictures, rom info, kernel info, app info, modem info, battery info etc! No pic, no proof!!!
This is the best I have been able to get with my phone with:
Bionix 1.3.1 - Stock kernel - KB1 modem - TW launcher - auto brightness off, set about 2 clicks from the left - battery calibration app used at 100% - Stock battery. Light / Light moderate usage, phone calls, texts, web searches. GPS on.

Well, this is great battery life you got there For me 24h is the most I can squeeze from my Vibrant with Project V/Bullet 1.42 kernel, auto brightness off, moderate usage. 16h with heavy usage... It's fully charged now so I don't have pics to show it
i used around 5% with in an hour with somewhat heavy usage this is cm7 nightly 71 bali with uv
srdjav - have you tried bali uv? I heard it works really well, especially with bi-winning, but I have heard great things about it on all different types of roms
gamikzone - impressive for cm7, I have read horror stories that the battery life on it wasn't all that great...but I guess with the kernel script and bali, it's way better!
@corpsetomb
Yes, I did tried Bali... But honestly, didn't see much difference in battery life. I have tried 4 different kernel on Project V and battery life was always 16-24h, depends of the usage. With extremely heavy usage 16h... So i decided to stay with Bullet 1.42.
But I didn't try Bi-Winning ROM yet... Maybe I will give it a try
But I had very bad experience with Super_DragonMODz 1.5 kernel... For a few hours everything was ok. But in one moment I picked up a phone after doing nothing for a half an hour and it was HOT! And I could smell "burning" inside Luckily when I took battery out and let the phone cool down, it was ok
Can we see pictures not words :/

haha what is this, a courtroom?
truly, none of this matters. one big factor in battery life is application use. in order to pinpoint someones battery usage, one would have to list, in detail, their application usage. which/how many apps poll for background data/how often? is the person using an autokiller/ram optimizer? which/how many apps stay open in the background, even when killed?
The bottom line is, battery life is ultimately determined by the user. there are only so many differences, in terms of battery, between these roms and kernels. none of them will give you a SIGNIFICANT difference. this is not the fault of the devs, they are not magicians.
This is why people do not get nice responses in rom/kernel threads when they ask "how is the battery life?". Then some clown who is a very light user will say "its great! i get 20hrs per cycle!!" and then you flash it expecting ground-shaking results...only you forgot that you have 317 apps on your phone (20 of which are constantly poll/checking for background data), and you use your phone/data like a whore who youll never see again. and unfortunately, there are horrible noobs out in there who, after doing this, will actually go back into the thread and say something like "DO NOT FLASH, MY BATTERY DOESNT EVEN LAST 8 HRS!!!!"
Theres only one true way to REALLY compare battery between ROMs/kernels (and it still isnt 100%trustworthy): download a ROM, try it out for a few days at moderate usage. Then flash the one you want to compare it to. Make sure you have the SAME exact setup as the ROM before (apps, brightness, GPS on/off, background data, etc.), and try to mimmick your usage with the other one. NOW you can effectively determine, relatively, which ROM may show better battery results for everybody. and then, when someone asks "does this have good battery?" you dont just say yes; you say "yes, i have seen noticeable improvement since coming from _______ rom, i about ___hrs more per full charge "
sorry for the rant

@TopShelf10
No worries, I welcome your input! I agree that a big factor in battery life is application use. You will see in the OP that I recommended people put in as much detail as possible along with their picture, such as what type of use, kernel, rom, etc. I would also like to hear and see comparisons between roms, that is part of what this thread is all about! To be able to compare different roms and see what helps based on usage.
Thank you for participating and your input!

You can manipulate the battery use stats pretty easily... at least on CM7. If I plug my phone in to charge for an hour, it doesn't reset my battery usage. Sometimes when I look at it it will say 24 hours+. Which I know is not at all accurate.

Android OS battery bug fixed on 4.0.4

Edit : I've done a new test but tapatalk doesn't let me upload files when editing post. So link to that post : http://forum.xda-developers.com/showthread.php?p=22078149
You guys probably all know about the Android OS battery bug that is present in ICS. But I recently flashed 4.0.4 stock leaked rom(it is for 4g but evilisto ported it for Nexus S) and I've used it for about 4 and a half hour. Then I went to battery tab to check my battery and saw this.

Don't be too quick to praise it. Make sure there is a difference in battery life with the same usage and setup, before and after.
Dianne stated on google+ that the equation that shows awake time on the AOS service was slightly messed up (adding screen on time instead of subectracting it, basically). I don't know for sure, but this could change the battery use percentage for AOS making it seem like it's using more than it is. Not enough reliable info to come to conclusions here. But do just make sure it is getting better life with the SAME use. Sometimes it's easy to trust a number.

It never was a bug, Dianne Hackborn said, the "Android OS" is actually many things like kernel stuff and it doesn't affect battery life. They just changed what is logged under Android OS now. So don't expect a sudden "magical battery life". It was pure cosmetics. For source check Dianne Hackborns posts on Google+.
Btw, you get the best battery life, when you don't look at the meter all the time.

They didn't state officially anything about a global update pull. A google employee only said, that they can limit the OTA install on some areas if they want. I got the OTA at the same time, as I reverted to GB for a week.
It's easy to see here, how some info gets misinterpreted and taken as a fact.
I flashed it on my 9023 (GSM), the android OS seems to drop a lot in battery use.
the major bug in 4.0.4 is the battery lift I think, so google should fix it this time.

They have disabled all OTA updates for i9020 and i9023 in many countries (it affects all updates, not just ICS). And there are plenty of reports of terrible battery life. It doesn't take much to figure out that one of the issues they are working on is fixing battery life in 4.0.4 which will most likely rollout to the GSM versions eventually.

I'm thinking of getting this phone, but in every review, they say the battery life is pretty crappy... can somone please share their experiences or stats on this please?
Thanks!
Nobody has one yet....

even if it is horrible. These press units aren't being used "normally" or lightly. They are constantly being hammered to get every last thing about it to talk about.
We have kernels and roms to go on. My Galaxy Nexus last 35 hours on a single charge on a stock battery. While some people struggle to get even 10 hours on it.

Exactly. my guess is also that it's because of the phone not being in the final software. Otherwise how could the same battery prove that worse compared to ICS lg Optimus? Jelly bean had a much better battery life in general too...
And IMO that is also the reason for the poor performance
Let's hope everything will be alright after the software update

LG Nexus 4 Battery Easily Replaced

The trend toward devices with internal batteries, ones that can’t be replaced, has come at the dismay of many power users who often need to switch to a fresh battery in the middle of the day. The Nexus 4 has a “non-removable” battery like most people expected, but it looks like it might be a lot easier to access than many might assume. You’re probably not going to make a battery swap in the middle of the day, but if you run into an issue with the battery, at least you know it won’t be impossible to replace.
Defective batteries and burn-out are a real concern with modern mobile device batteries, and while it may be fairly rare for something to go wrong, anyone with a smartphone who’s not willing to disassemble the entire device can tell you how frustrating it is to lose a phone to a bad battery. On November 2, a follower of Brian Klug, Senior Editor for Anandtech.com, sent him a tweet about battery replacement for the Nexus 4 on Twitter. Mr. Klug responded:
@aatifsumar there are two torx screws, then some plastic clips, it’s easy
Aatif pushed for a little more information and Mr. Klug responded with a great photo of the battery situation:
@aatifsumar two screws, boomhttp://twitpic.com/b9pbsj
The 2100mAh battery should be fairly capable of handling a day of moderate use, but for the fear of battery failure this is great news. Mr. Krug came through with another photo a little later giving a bigger picture of the situation.

Doesn't really solve anything anyone is talking about here. Being able to replace defective batteries is a separate issue from the phone's poor battery life.
Options:
1. If the info from me is usefull for you then push the "Thanks" button, cause all i want is to help you!
2. If not, read more!
3. Life is too short for other options!

Every review? No, engadget u mean? Most reviews had battery life as good to excellent for a smart phone. Dont panic and it is certainly not every review.

i think they plugged in charger at the red square
surely, it is impossible to reach 16 hour
Yes that's true. The nexus 4 consumes lot of battery life when the wifi is used.
I take all these battery complaints with a grain of salt. First, software was not final. I find it hard to believe it is going to be THAT much different than Optimus G.
Something else -- I had a friend who got a US GS III and had terrible battery life despite doing everything. Exchanged for a new one and battery life was double the first one. Do you think any of these "get it out first" reviewers considered this as a possibility? Heck, most of them didn't even mention that Google told them the OS code was not final.
It is worth noting that LG has had battery issues in the past. Was one of the reasons I didn't get an LG last year.
I'm finding the battery life to be pretty good. Over 36 hours and still going for light use. By light use, I mean I played a couple of videos, made a couple of calls, general internet surfing, lots of drop box syncing and more. Mostly all over Wifi. Also some wifi tethering for an hour or so. I also find that the battery charges quicker than normal too. Hope this helps

This I had my phone use 35% in 6 hours. That with usage.

4.2.2 update turned the sceen a vampire ready to suck my battery life

Well the topic tells pretty everything i used to have no real issues with the battery life of my phone, till i got the kitkat update. Since then as soon sa i turn the screen on i can really see the battery % drop. I mean 1% for minute of usage. And the back turns Hot.
I'm pretty confused since i have not read such kind of problem around here. I already greenified what i can (no root). And hard and chache reset too..
Any other idea about the nature of the issue (9005 model) Tank you!!
You forgot the garlic.
Those Samsung battery draining problems are really getting ridiculous. But what's funny, i owned 5 Samsung phones till now, but never had any issues. I know, I'm not helping...

This is my first samsung device, and actually i was really happy about my battery life and when i got the notification of the 4.4.2 update i was even more happy cause i was sure that it would have improved it even more. LOL.
What amazes me is that even if there's clearly something wrong, and even if the note is a company flagship, there is no plan for a patch -.-

Try a fresh flash and wipe the device, usually fixes it.

A fresh stock flash won't trip Knox no. So long as you are flashing
A)The same firmware
B)Not trying to downgrade
---
Grab the stock ROM you require from one of the threads in the General section of the Note sub forum.
Grab Odin 1.85.
Once you download the .zip file, unzip and you should get an .md5 file around 2GB in size.
Put your phone into download mode, plug into PC, fire up Odin and load the .md5 file into PDA/AP slot. Hit start. Grab a beer and chill until it has finished.
Have a read through the threads with the different ROMs though, sometimes there can be minor issues with file sizes etc which then require a PIT file, but you should be OK tbh

Look at usage under settings, general, battery. if you see mm-qcamera-daemon at the top....you've got a known issue with KitKat.

I installed battery doctor and the problem disappeared with a default diagnosis and optimisation. I'm rooted, not sure if that makes any difference.
Clicky
I'd really like to root my phone and finally have some serious fun with it, but i'm not really a guy who like to take a risk like this.. It's not a budget phone and i do not want to pay for some factory issue, even if this is a real bad move by samsung and i won't ever buy a samsung device again for this reason, but in the meanwhile i have to try to take the best from my unrooted phone.
I've already read the camera issue, my note do not fall into it.. As i said the Phone act very good and is really energy savvy, until i wake up the screen, this literally drinks the battery juice.. 1% per minute! Less or more.. And no matter if i lower the screen brightness.
As soon as i'll have some spare time i'll try that fresh flash procedure

n00b's bro. Mistake, just like allowing them on this forum.
Same as everyone having issues with battery life on the Note 3 /w 4.4.2. All n00bs.
The very fact that n00bs think that Sammy would release a ROM with obvious issues? No. Not going to happen.
The issue lies with the end user. Period.

Yep, join the KitKat bug club. Note 3 users are having horrendous battery drain issues with 4.4 along with wifi instability and cellular network drops. I went through 3 Note 3's until I finally gave up and decided to stick with 4.3, the hassle was not worth it at all.
My battery usage went to crap with Kitkat.

I got this issue and solved it in this way;
let ur phone to discharge ~15% or less
then turn off ur phone and connect it to charger
and let it to charge 100% then turn ur phone on.
It s like re-gauge battery.
there s some apps for it on some laptops but nothing yet for smartPhones
:good:

Had to do this with multiple phones before. By doing this and factory resetting I can guarantee you will not have issues with battery drainage.

Then why is mine perfectly fine?
Exact same as Jelly Bean. The radio acts a bit different, battery life is identical.
I still think these are the dreaded PEBKAC error. Or in this case a "PEBPAC" error.
Flashed mine with Odin 3.09... hmm.

battery life falling off a cliff

So this has been happening with my battery lately - it's chugging along no problem, then the second my phone hits 30%, it dies completely, and when you hook it up to a charger, it starts charging from 0%.
This has happened with multiple replacement batteries already. Anyone know what's up?

Was an issue for me back when my battery was bulging. You might want to try and recalibrate the battery if it's new by charging it overnight, if not new then get a new one. If that doesn't help, factory reset. If problem continues, take it to Samsung.

I had the same exact problem with mu Note 10.1 2014 edition. Then I downloaded a battery calibration app. The one I downloaded is made by a developer by the name NeMa. It worked as stated. Couldn not be happier. But, it needs Root. And does not ask for ridiculous permissions. Give it, or another one a shot and report back.
Sent from my SM-N910V using Tapatalk
Guys, for years now it's been proven that battery calibration is a myth. The act of charging the battery to 100% has the same effect as it does the same thing as a battery calibration app: delete the batterystats.bin file.
The problem is either with the battery or the charging circuit in the phone. Take it to Samsung and have it looked at, because a battery calibration app won't work here, despite claims to the contrary.

It has been proven as much as evolution. And that is about zero. No proof. It is a theory. Now, you are of the opinion that it is a myth. I am of the persuasion that it is not. Seeing as my Note 10.1, SGS3, and SGS4 all had battery issues for long periods of time. Then I remembered that there is this "myth" called battery calibration. After trying out the "myth", my wife's phone no longer shuts down randomly, my Note 10.1 does not go from 30% to dead instantly and neither does my SGS3. All have batteries that now last exactly as long as the manufacturer specs them out to. And non of them freez up and or shut down any more. All of these devices have been going through these problems for many months now. Tried the "myth". No more problems for this past week. And there are not going to be problems.
So, in my case, the "myth" has gone from the act of being "myth" to fact. Until your device start acting up where battery stats play a roll, then it will stay as such. A myth. Now, if the battery has been through to many charging cycles, then it is probably old and on its way out. In that instance, no battery calibration will bring it back from the state of dying. At that point, it is time to get a new battery.

So you belive everything that you see on TV as well? I suppose that the Internet must be God to you. I mean, there is an http link for everything. Must be fact.
How would you like to explain what happen ed d to all three of my devices that were having g battery issues. SGS3, Would charge to 100% drain down rapidly and when it hit 30% it would just shut down.
SGS4, would drain down to nothing at random and shut down at random. Even in the middle of a call. Note 10.1 2014 edition would drain down extremely fast, and I mean fast. It also would shut down. That one I did replace the battery on. And it still did it. All of these problems have persisted for several months now. Only a week ago did I try the calibration method. Which I am aware, using an app is the short way around deleting the file for the battery. At any rate, all devices are back to normal operations. By the way, I put the old battery back into my Note 10.1, and did the recalibration. AL is well with it also. But, the Internet must be telling the truth. Plain and simple, calibration will not fix a broken battery. It will however reset the part on the system that reads the battery correct and tell the OS what to do with those numbers. In the case of the case of these, my devices, there are no more shut downs happening. Or was all that in my head for months? Probably just a placebo effect? Yeah, that's what it was. The Internet says so. Lol! I'm going to put up a link to a YouTube video that shows that horses are pink.

By the way, I am just having fun with you and bust your chops. Lol! But I still stand by my statements of calibration. It works in some scenarios. Particularly when switching ROMs.
Sent from my SM-N910V using Tapatalk
On my old Gingerbread device, I used Nema's Battery Calibration app. Once I read the information from the Google engineer in the link I provided, I stopped, and haven't touched a battery calibration app since. In my experience, calibrating the battery is a needless step, because you aren't actually doing anything to the battery itself or the circuitry within it. For example, you mention using it after changing ROMs. Why? My battery life has not been affected from all the ROM switches I've made in the last year, and I've made plenty of them.
If a battery calibration app were to actually recondition the battery, then I would say such an app is useful. Instead, you have a placebo effect brought about by an app that does nothing that Android itself doesn't already do. So why waste the time, the energy, and the (minuscule) storage space?
Google make Android. So if they say that batterystats.bin has no effect on actual battery life and such, then it must be true. I mean they are the ones who made the damn file, they should know what it relates to.
The reason why your 3 devices worked again after a battery calibration might be something else. Maybe the app you used did something else other than just delete batterystats.bin file.
I also used to calibrate my battery on my old Gingerbread device. But honestly, I didn't see any improvement in battery life by doing this. Nor did I see any worsening in the battery life or sudded death by not calibrating.

First, Google did not make Android. They purchased it and now modify it. But that is besides the point.
Sorry, but the app that I used did one thing and one thing only. And that was clear the file. It did nothing else. Can you tell me what if not battery stats, would make all three of my devices behave properly? Because I would love to know, as would the rest of the community. I seriously do not particularly care what Google stated. I care what was happening with my devices. And they were not working. I used an app to clear a file that has to do with the batteries. All of my devices work exactly as they should. Google can tell me that all rainbows are silver. But, my devices are not telling me one thing about my batteries while something else is the case. And my devices are not shutting down on their own either. So, 3-4 months of serious charging, readouts , and performance issues all cleared up after the use of an app. I am confident coincidence is not the case. But thank you for your disbelief in something. Absolutely appreciated. Plain and simple people, if you are having batteries issues. Try the simplest method. A calibration app. If it works, then great. If not, move on to the next step. Try different charger and or cable. If that fails, chances are that the battery is on its last leg. Replace it. Nothing more, nothing less. Zero arguments to be had. Nothing to prove. Or disprove. If any one is of the persuasion that a calibration app is a waste of time, don't use one. Also a simple thing to not do.
