No point in wiping battery stats.

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.

[Q] Weird battery issue when using TWRP to backup

I have a very strange problem. I can't decide if there's something wrong with TWRP or with my Nexus 4. Here's the series of events:
1) I want to backup my phone using TWRP 2.3.2.3 that I have installed.
2) Battery is at ~58%
3) I plug the N4 into my wall charger.
4) Reboot into TWRP and start a backup, with everything checked to backup, using compression.
5) TWRP shows battery is "58%+" (I assume "+" means charging)
6) A couple minutes into the backup the screen goes dark.
7) I press the power button and get a battery charging symbol. I press again and eventually boot into Android.
8) Battery is at 1-2%
How can my battery go from ~58% to almost 0% in two minutes, especially when it's on the charger?
To make things even more strange:
1) I wait until battery is charged to 100%
2) Reboot into TWRP and start the exact same backup.
3) It completes successfully, reboots into Android, and battery now shows at ~92%
What is going on here?

Slight battery loss is normal upon a reboot. As to your first issue... beats me. I doubt it's a problem with the phone. Maybe a one off.

I'm not so concerned about the battery going down when backing up. I would expect that. Although with it being plugged in you wouldn't think...
But the part where it suddenly dropped to near 0%... if it only happened once, maybe, but this has happened twice when my battery was not at or near 100%. I suspect it would do it every time.
I was just wondering if anyone else had experienced something like this?

As a constant ROM/MOD flasher over the past 2 weeks of having this phone I have not had any similar issues.

Loosing 20-30% at once after doing something like backup in recovery is unlikely, but possible.

Have you ever flashed/backed up using TWRP when battery wasn't near full?
I have a Nexus 7 and have never had this issue.

Even when plugged in?
What about a 50-60% drop after two minutes of backing up?
If I'm the only one, I might have to RMA my phone.

Try 2-3 times the same scenario, then switch to CWM and repeat the procedure. Then you'll know where is the problem, for sure.

That sounds like a GREAT idea. Thanks, I'll try that. Although I was hoping to use TWRP because it compresses backups, and my N4 is in danger of running out of space. But it would be worth trying just to see if it works.

I doubt you can charge whilst in recovery. I'm sure cwm will not let you charge even of you shat your pants ....

I thought charging would be a hardware thing, so it should do that no matter what your phone was doing. ?? Besides, TWRP shows a "+" next to the battery percentage when plugged in. It's not there otherwise, so...

I've had this issue happen a few times on my i777 S2. The phone would randomly reboot and the battery would drop down to <10%. I've had it happen at an original 90%, 50%, you name it. I chalked it up to issues with the battery.

Ok, so I installed CWM, but then ran into some threads that said it had issues with JB 4.2. As in, it doesn't know how to properly handle the new "/sdcard/0/" folder structure that was introduced for multi-user support. So, I chickened out and went back to TWRP. But then TWRP did another 55% battery to 0% battery crash again. Only when I have a lot of battery left will it actually complete. *sigh* I will try CWM again, at a similar battery level, to see what happens.

So what did you do with that phone? I'm considering an RMA, especially since I seem to be the only N4 owner on here with this issue.
When mine crashes, it doesn't finish the backup and it goes to a blank screen. Only after having it plugged in for a minute or so will it actually start up. Like the battery was completely empty. And it only seems to happen when the % left is under maybe 70%. It's always completed in the 90% range.

RMAing this early in the life of the phone is a waste. How do you it isnt a bug with twrp. I would wait it out for a bit. I also feel nanodroids are over rated. Titanium Backup makes things so easy. Since the bug happens only when doing that one thing it sounds like a bug with twrp.

I can't imagine a bug in recovery that is able to deplete your battery 50%+ within 30 seconds. Another weird thing happened: I was at ~70% and then rebooted into TWRP, which then immediately had the battery at ~20%. I rebooted back into Android and it had the same thing. I didn't even kick off a backup or anything. ??? See the screenshots here to see the two dramatic cliff drops I've had, one earlier today the other a few minutes ago.
I will wait on the RMA to see how things go WITHOUT using TWRP for backups. I think nandroids are very annoying to make and use, but I didn't want to learn how to use Titanium (it *looks* complicated). I think I'll look into that now though.

Do us a favor... There is no issues with CWM & 4.2. Do your CWM checks, don't waste time.

I'm not sure what all the issues were that I was reading about, but one I experienced was not seeing the CWM backup folder when connected to my computer. I like to transfer them there to save space on my phone. CWM puts it in the wrong folder for that in JB 4.2, although I think it can be moved.
I'm looking into Titanium now.

I have to say, as a former iPhone 3GS owner, that Apple made all this backup/restore stuff drop dead simple. Completely and utterly automatic even. Your average user would NOT be able to figure this out on an Android phone.

It wasn't that much of an issue for me since I had multiple batteries. It would happen about once a week. The battery would soon and I would pop in a new battery. Ended up selling the phone to fund my Nexus.

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!!

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

I installed battery doctor and the problem disappeared with a default diagnosis and optimisation. I'm rooted, not sure if that makes any difference.

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

Same as everyone having issues with battery life on the Note 3 /w 4.4.2. All n00bs.

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.

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

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.

Android System issue?

ive been looking all around, with no solution so far, but the issue im having is that the battery stats show my phones having android system at 35% most of the time and android OS following it around 15-20%
is this an issue with marshmallow or samsung? I havent even rooted the phone, its simple the way it was since first turning it on.
I installed package disabler and took out knox and other things, but still no change...so im a bit lost

I initially had this issue as well. I got it down to under 20% by doing the following:
1. No diagnostic reporting to Samsung
2. No feedback/reporting to Google
3. Turn off sync & turn it on manually only when needed (I use a macro app to automate this, called MacroDroid)

Mine is doing the same thing. Was pretty pumped about the big battery but with that drain it's not any better than any other battery. Sometimes doesn't even last thw whole day. I'm not a heavy user either.

Remember that all the battery usage percentages MUST add up to 100%. The less other apps and processes are using battery, the higher the percentage used by Android system and the OS is going to be. If you let your phone sit unused for 3 or 4 days, those two things would probably total 70 or 80%, just because nothing else is using battery.
Don't worry about the percentage system is using. Look at your overall battery life. If that's good, then don't sweat the small stuff.

For # 2, Settings / Applications. Scroll all the way to the bottom and tap Google. Then 3 dot menu / Usage and diagnostics. Make sure it's off.
Not sure about # 1

Also having the same issues here. Experienced Android user, disabled quite a few apps, non rooted. Let's figure this out guys!

AT&T sent out an update that lowered the android system battery usage. Hopefully Sprint will be next.

It's not mentioned explicitly in the changelog. But AT&T GS7E users have reported battery life improvements, just like the T-Mobile guys.
My GS6E received the April update yesterday & Android System doesn't even show up anymore in battery stats. Battery life improved.

Are you guys having Android System battery issues still?
To pinpoint which service within Android System is causing the most wakelocks without Root, you can use this app (Wakelock Detector Lite) & adb to view the stats.
Here's the link to the Play Store app.
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector.noroot
After you install the app, go into Settings > Developer options & turn on USB Debugging.
Then connect your phone to your PC, open adb, and type:
adb devices
Then
adb tcpip 5555
Now you can view your wakelock stats without root!
My number one wakelock within Android System is GpsLocationProvider_ex. It prevents my phone from deep sleep & Doze.
The only workaround is to turn off GPS until needed.
Please share your findings.

I got much better results yesterday.
17 hrs off the charger & SOT of 4 hrs & 42 mins.
GpsLocationProvider_ex wakelock of only 3 mins & 51 seconds using the GPS+WiFi+Mobile location setting.
My settings:
-Firmware version PD3 (Sprint GS7E)
-auto brightness
-sync off
-Location = GPS+WiFi+Mobile
-WiFi & Mobile data always toggled on
-Bluetooth always on & connected to Gear S2 3G
-No power-saving mode
-Google Now & Now on Tap on
-Push apps running: Kakaotalk, Slice, Pushbullet
-140 apps installed
Before the refresh, this was the kind of crazy GPS wakelocks I was getting:
Finished yesterday with over 6 hrs of SOT.

Yes, those apps only refresh automatically when I open them which is how I like it. I don't like getting pestered with constant notifications. And I don't use Facebook.
I use macro apps to automatically turn on Sync when it's on the charger & shut off when taken off the charger.

Battery Life on Recent Nougat OTA

Question.. How is everyone else's battery life been so far on Android N? Mine has been atrocious and it's mainly due to Bluetooth. I did a clean install by flashing the recent google image (MTC20F) in ADB then enrolling my Nexus in the beta program and getting the N OTA. I charged my phone to 100% then left for the gym around 5am, got home at 7:40am and my battery is down to 46% from just listening to Pandora, Spotify via bluetooth. Here are some screenshots.. I was getting significantly better battery life on Pure Nexus Rom.. Also, I am stock and not rooted or using any custom tweaks. It's 100% Stock

Try installing the EX kernel and disabling touchboost under the CPU settings. I get ~40 hours battery life with normal usage. If you tweaked the settings i am sure you would get 2 days easy.

First cycle is today. Doing good...

Mine is doing the exact same thing as the op's. Bluetooth is just killing the battery too but I am on stock, not rooted or anything. I went from 89% to 26% in a span of 3 hours with Bluetooth and Spotify on in my car and at the gym. I have taken out almost all 3rd party apps, which seems to have helped but this morning as the Bluetooth was on (for Spotify and Waze) during my commute to work, it went right down to 75% from 100% in a span of 45 minutes and that's with the screen OFF. On Android M, the most it had gone down to was to 88%. 75% is ridiculous.
With Bluetooth off, the phone seems to be doing OK ? Android OS and Android System are eating up the battery.
I will do the factory reset tonight and hope for the best but this is the worst battery life I've ever seen on my phone.

Great.... So N does not fix whatever the hell bug started in MM with Android system and os.
That's not good news..
Thanks for reports though.
Keep them coming.

There is a thread for just about every phone that has MM.
Look around for Android System and Android OS.
Not in LP.

I don't know what Bluetooth and android system/os issues you are mentioning, but I did a clean stock restore with factory images from Pure Nexus then took the OTA through system update, all was good, did a factory data reset, pushed twrp 3.0.2-1 then then supersu 2.76 and took most of the Google stuff I don't use out.
No issues what's so ever. Battery is great. I'm losing about 10% battery for every 45-50 min sot. And the new doze is working flawlessly. I lost 1% battery overnight in 7.5 hours. Yesterday Gsam battery monitor showed my phone was in light or deep doze in 7:20 out over 9.5 hours of charge with 2 hours sot.
I'm only rooted with some debloat and TiBu and battery apps gsam and wakelock detector

It's not BT guys. It's your music streaming. Bet if you moved to an app that uses on board music and tested it you would find you have better battery life.

I'm stock and not rooted with any mods.. Just find it weird.. On PN Rom my battery life was fantastic with Elemental X Kernel..

I went back to all stock and non rooted.. Wanted to just try N pure without any mods but I guess that might have to change.

I don't think that's the issue seeing as how you can download your spotify playlist to your phone which I do.. Not to mention in my screenshot, Spotify wasn't the root of the issue, the Bluetooth was at 20%.. Nothing else was close..

Look at the cell connection. There are 2 major factors normally to battery drain. 1. SOT and 2. Cell connectivity. As an example. It doesnt matter how big of a battery I use or the device. I can easily kill the battery on any phone within 4 hours without even touching it due to cell signal.

Normally I would agree with you but in the screenshots I posted (not sure why they're so small), my SOT was only 16 mins and my LTE connection was at full strength. I never had these issues when I was using Pure Nexus Rom and I was using that ROM since October of last year with the same exact setup and haven't moved from my current apt.. Literally haven't done anything differently from that Rom to Nougat and for some reason, bluetooth is killing my battery. In the pics I posted where it shows what's eating battery, it was at 20% and the next thing was 9%.. Spotify was at 3% and Pandora was around 3%..

Custom roms change how things work like that. Like I noticed on a few roms they will throttle the data when the device is off.
Those stats really are kinda misleading. What ever you use the most will always be at top. No matter how much it uses. As an example. for 30 min say you use youtube the most and the next 30 you use spotify the most. You will see them swap off when you look at what is draining your battery.
Also you have to remember that with the new update many things have changed system wide. If it were me. I would pull a logcat. I dont have the official yet for my nexus 6 so still on the developer preview and I run BT all day long using power amp and it bearly touches the battery. Mind you that could just be issue with the 7.0 update which is why they are already working on 7.1 to be released in a few weeks.

Very good point.. I'll continue to monitor it over the next few days, if all else fails I will just go back to a custom rom and wait for 7.1... Thanks for the info

Here is my current SS. Yes it is only a couple of hours but I connect my BT headset the min I wake up and it stays on all day long.

That's how mine was when I was using a custom rom.. Never saw Bluetooth on there before and I used it often as well.. Not sure what the issue is.. It's really weird

Grab a logcat. Did you take an OTA or do a full complete redo for the update? I am shooting in the dark myself really. Just suggesting what I would do. I also dont use streaming music apps. I keep all my music on device for many reasons.

I did a factory reset. Thought it fixed my Bluetooth drain as I had Spotify on and Waze while connected to my car this morning. Usually by the time I get to work after 45-50 minutes, I'd be down to 88% from 100% (with a few 3rd party apps installed). Thought it was fixed as I only went down to 96% for the duration of my commute (with minimal 3rd party apps installed).
However, the Bluetooth drain showed up again when I connected my Bluetooth headphones for use in the gym. The drain was not as drastic as I reported earlier. However, it still took up a nice chunk and Bluetooth again is sitting at the top of my battery usage list along with Android System and Android OS. The phone is at least acceptable now but I have no idea why it is draining as quickly now when it never used to do this before when I was on Android M. It's not like I changed my routine or usage habits.
Also, I am on stock, not rooted or anything so really not sure what is going on. Maybe I will just wait for a patch or something.
