[Q] Battery defect or rom issue?

Hello!
Sorry I can't post this in the Paranoid Android thread yet. As a noob I can't post in that forum until I have 10 posts so I'm at a loss as to where I should post this.
Anyway, I just put the new 2.1799 PA ROM on my Nexus 7. Unfortunately, I seem to have a serious battery drain when the screen is on. I have read many posts where people claim to have easily achieved 6+ hours of active screen time per battery charge whereas I'm only getting 3-4 hours of active screen time per charge, almost all of it related to web surfing. I have a strong wifi signal and I keep my screen brightness around 20/30 range. I'm not sure if it's the ROM or if my battery is defective.
I have also read about a battery calibration app through a different thread. Is that necessary for the PA ROM? I didn't see anything in the tutorial mentioning a battery calibration.
Included are two pictures, although they aren't very indicative of my problem as my tablet was sitting in my backpack for most the day.
Please tell me I'm just being paranoid! Thank you for the help!

The battery recalibration is a myth, but there is also no harm in trying it.
according to the pics you have attached, there doesn't seem to be anything wrong.
Battery also drains faster if you have too many apps that have services running.
Ex: Facebook.

I know there is a battery warranty, but how bad does it have to be to get it replaced? My battery cannot reach the 9.5hrs of 720p video playback (with headphones in) as achieved by Asus. I can only get 8hrs. From normal usage, I am only able to get 6 hours.

The ROM has less to do with the battery than the kernel does.
I would say try flashing another kernel. The default cyanogenmod kernel that comes with Paranoid Android didn't give me very good battery life.
Franco kernel gives me excellent battery life. Other good ones for battery are Faux or Motley.

That is in the normal range i would say, Companies usually exaggerate.
As suggested try franco's kernel.
He has a free kernel flashing app on the play store.

My issue is with how the battery percentage is running down......
Charge the N7 to max and use it for a good 2 hours and the battery STILL reads 100%.
Even if I then shut down and reboot it still shows 100%, then all of a sudden it will start to drop very slowly at first until it gets to around 40% which it then shuts down and will not reboot, obviously void of any battery cells.
Clearly it's a calibration issue.
This is on a stock non-rooted machine.

I tried his kernal. I did my video play back test and I got the same 8 hours as before. During normal usage I think I will get about 30-40 more minutes. Still not what others are getting

Try a factory reset. If that doesn't work, you're more than likely actually looking at it being a hardware issue.

Factory reset was the very first thing I tried when it started playing up.... I'm hoping when 4.1.2 rolls out it may clear it. If not then I'll have to look at doing a root and access the battery file to see if deleting may help.
Thing is a recharge should clear out the battery file stats and calibrate, which clearly it's not.
Apart from this the N7 is flawless so it's staying with me. Running hours is the same, just doesn't give an accurate reading of how the battery is running down.
It's not a big issue.... to be honest I'm more curious than annoyed.

Have you tried installing a 3rd party battery app to see if it registers the correct battery output? This is the one I have used, works good. GL

You do realize that wiping batterystats.bin has absolutely nothing to do with the battery fuel gauge, right? It does not "calibrate" the battery or affect reported charge. The myth of wiping battery stats has long since been debunked by Google's Android engineers. The only info contained in the file is a list of apps that used battery since the last full charge.
The only other thing you could do besides a factory reset is see if 4.1.2 fixes it for you. If not, then it's definitely hardware causing the issue- the battery charge is likely being improperly read and reported by the battery itself.

Kitkat killed battery life

Kitkat killed battery life. Used to be great, now it sucks.
Sent from my SM-P600 using XDA Premium HD app

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.

I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time

Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.

I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.

4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.

I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.

You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

Agree and disagree!
I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

I don't have this issue but maybe affected people should read this : http://forum.xda-developers.com/showpost.php?p=52366635&postcount=236

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.

Factory reset and see if it still happens. A dirty flash can do weird stuff...

Yeah, im not getting great battery life either since this update. I just reset the tablet in the hope of tracking down what's the issue.
Troubling, since battery life was so great previously.

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.

Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.

If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.

Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.

Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.

So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.

This is what happened when I replaced Nexus 5X battery with a new one

Tired of getting 2h30 SOT (plugging off power at 7 am and needing to plug on again at 2 pm) I decided to spend a few bucks on a new battery. I own a nexus 5x for 10 months, so I thought maybe battery has been underperforming.
I've ordered also the needed tools so I could do the job myself. Very easy by the way.
I was excited to see how the brand new battery would perform the next day. So I plugged off power at 7 am and 2 pm I needed to plug back on power (2h30 sot). YEAH, I HAD NO IMPROVE AT ALL with a new battery.
Maybe it's that I have too many apps (100 at about), but I'm not the one who lives with whatsapp only.
So in order to relieve the pain of not getting through out the day I've bought an S7 edge and now I can settle down so I know I will get past through the day. I dislike many things on S7, like the crap fingerprint sensor and the inconsistent physical home button, but I'll try to live with it. My next bet would be the Xperia XZ, so I'm still considering.
So it was an unburden, but I feel I can help someone out with this experience.

Have you tried a third rom or ex kernel?

im kinda in the same boat. just received my 2nd replacement battery today... gonna see how the battery compares tomorrow with stock unrooted. if no change i'll be trying purenexus + elementalx with Hawktail 1.2 profile.... such a struggle with this phone........

I don't know about you, but my typical work day I range from 6-7 hours with around 3.5 SoT average. That's pretty okay, given how low our batteries are for this phone. I use SimpleAOSP + Franco kernel.

I deal with it by having a 10000 mAh battery bank handy in my work bag or car.

I know.
Since I have updated to Nougat, I have only 2 to 3 SOT. Also with franco kernel or elemtalx no improvement, no matter which profile.
Marchmallow was better with the battery performance.
I will try pure nexus with custom kernel (franco or elementalx).
I'm also wondering why the Android operating system has such a big battery consumption according to "betterbatterystats".
Otherwise always it was the google services.

A few questions
Which time do you plug off and on to power again? I mean, how many hours do you stay off the wall outlet?
How many apps do you have installed?
Do you use antes app/kernel for the purpose off extending battery life?
Thanks!

Mostly every night. Sometimes it gets me to 2 days of battery life. Im pretty heavy user
I have about 50 apps but i am very careful about apps i install and use. When i am at home on wifi all day it gets me 6-7 hrs SOT. I used most of the kernels i found on the XDA but now i am settled with minimalistic ABC rom with implemented DU kernel.

at first i was getting the same results but i've made some major improvements by using airplane mode when at work with wifi, greenifying almost all of my apps, removing Fitbit sync/notifications, and using the greenify manual hiberate now widget. getting over 2hrs of SoT now but it's still nowhere near the results I've seen from others using PureNexus Rom + ElementalX kernel (Hawktail 1.2 profile)

The battery of my Nexus 5x (not rooted) seemed to be nearly dead. Smartphone shut down at 50%, and sometimes the battery went down from 80% to 30% within a minute. Then suddenly the mainboard of my Nexus died. The mainboard was replaced and Android was resetted. After this the battery works as if it's a new battery.

I dont really know what you do in order to get less than 3h SOT, or what brightness you run your device on, or what apps you have installed, or if you have NFC, location, Bluetooth or LTE turned on all the time, but on this phone it is the usage that determines battery life. I got a new Nexus 5x with an old battery and had the same results. Ordered a new battery for about 10$ and got arround 5-5:30 h of SOT with the same usage over arround 43 h of stand by withouth charging in between on full stock. You might want to check whata draining your battery or maybe you are a multitasker that streams music, types on FB, browses instagram all at the same time while the screen is on 40% brightness.

For me 5x battery sucks, i want to get 6p soon, but price is a little bit too high now so i must wait some time to buy.
Im using Jolla kernel now, with small cluster -> 3cores, 1,2GHZ and big cluster -> 2 core 768MHz max.All on zzmove. Battery is now improved, some times big cluster shuts off sometimes it's working, but performance is good for dialy use. Multitasking is fine, chrome web browsing also. ~ 4h 20mins of SOT, previously ~ 3h.
So i think NOW battery is really good for my 1yr old phone.

ROM and kernel are inconsequential to battery life in comparison to normal factors such as usage, settings and signal. Without reducing performance or functionality (GAPs) the most you could hope for is +10-20%, if even that.
Low screen time doesn't mean your battery life is bad as that's just one form of measuring battery life. If you do a lot of messaging and phone calls for instance you will never have long screen time as you need to actively be using the screen in order to increase SoT. If SoT is your only measure of battery life then you don't understand how it works.
I regularly see 5-6 hours SoT over 24+ hours without root or disabling much, as I use my phone for mostly browsing and streaming.
Post some screenshots in our Battery Thread and I will take a look. Replacing hardware should be the last option for improving battery life.

I think it's not about the battery, rom, kernel, settings, installed apps....
I think......it's only about the device
I tried EVERYTHING. changed battery, all android versions, tried without google account, kernels, profiles, custom roms, interactive settings, I don't even use many apps
my device has abnormal consumption. period.
I have 3 friends with n5x that do more than 4 hrs of screen on
mine does 2. and I can do nothing. it's just this
I don't know if warranty could cover such thing, it would be hard to detect on RMA since is very user related

You make me feel relieved. It must be the device. I've spent many bucks on S7 edge but I still prefer 5X ...

Use Greenify to kill some apps that work in background. If you are Facebook /Messenger user, to maximise the battery life uninstall them and use alternative one like the lite version of these. "Naptime" for aggressive doze. Greenify and Naptime gave to my phone nice battery life.... From 100% - 2% I have 4:15 - 4:30 SOT . All stock 7.1.2

Nap Time by Francisco Franco

Has anyone else tried Nap Time by Francisco Franco? Been using it on all my other phones and decided to give it a try on the 1P6T. Set it to aggressive doze and will keep thread updated on advantages or disadvantages.
I'll run a complete battery cycle using Nap Time and then another with it turned off.

Haven't installed it, have had it on previous devices. Will be interesting to follow your findings.

I feel like, with the combination of excellent out-of- the-box battery life and the Dash charging speed, there is not as much reason to skrimp and save on battery power by using Franco's excellent app.
When you can get screen on times that are practically all day and you can get a massive recharge in 10 -20 minutes ... I'm far less inclined to spend much time tweaking the kennel and searching for wake locks etc.
Franco makes good stuff though. Used his kernels for years.

Greenify and other nap apps are considered as useless in pie, native battery optimization is enough. I ditch them months ago without any visible difference.

The only thing I think will make a difference is Leandroid switching mobile data off when the screen goes off. This is a because of the Mobile Radio Active battery bug. That said I'm now a week in to my 6t and haven't noticed the drain, so it looks like OnePlus fixed it, OR, the battery is just so good it doesn't cause inadequate battery life anymore. (I've not rooted yet, which is a sign the phone is excellent.)

Will do. Even tho the battery life of the OP6T is great I believe it can be better. Just started with a full charge yesterday afternoon and when the battery is down I will post. Then I'll stop Nap Time and do another test.

@ggrant3876 how is it going?

I was just getting ready to post. It saves a bit on the battery and if it was a paid app not sure it would be worth the $. Since I have it installed and have run the 2 adb commands to give permissions I'll continue to use the app. If anything changes I'll post again.

Cool, thanks. Will try it out and see if the phone goes into deep sleep quicker than without it.

Nap Time works fantastic here, now gets pretty much instant deep sleep.
Sent from my OnePlus6T using XDA Labs

I've been using it also and I'm getting about 97% deep sleep while I sleep through the night

hi.. may i know if you guys remove naptime from the OOS battery optimization or not?

I tried this but nothing has helped the massive battery drain I've been getting since finally rooting the TMO variant. Google music is using like 80% of the battery and not going to sleep.

My battery has been awful on my phone since day 1 which was when I rooted. The last 6t I had for about 10 days , did not root, battery was much better. Going to try this app

I turned on "disable motion detection during doze" and notice that ambient display doesn't work on tap. It might be the case that it doesn't work when the phone is in deep doze. Hmm, a bug on oneplus's end?

+1

if im not wrong, the app will ask you to remove it from being optimize

I have now tried this for a few days and notice no changes in battery.
I do notice that it goes in doze mode more often and more quickly (gsam battery monitor) I don't see any difference at all other than that.

Hi, can I check if this is Naptime working normally?
