[Q] Posible fault of my battery? - Nexus 7 Q&A, Help & Troubleshooting

Hello
Please a little help.I got a nexus 7 from a week now.Is my first tablet and my first gadget with android.
When i bought it i saw on google specification that the baterry life is around 9h.I know that this will never be but...maybe a 5-6h can be done?Or is my baterry so bad?
Maxim that i manage to do was 2days 23h, 30 min with screen on 4h and 8 min.
Its ok like this?
Now..the bigger problem.Today i recharged it again and after that i just browse a bit and the baterry drop from 100% to 86%.(screen on was 58min)Dont think its ok to drop like that only just because i read some forums.
Android version is 4.2.1.I made the update but only that.(no root or some like that- the rest is just the original)
So..please can you tell me...i must go and ask for a new one?
Will try to put some pictures(the last 2 recharges),maybe will make a better opinion.
Thank you

Your N7 is perfectly fine. Were pretty much the same when it comes to battery life. I get 1day 5hr and 9min. with screen on 5hr and 32min. The 9hr life that google said is pure BS. Don't ever assume all the things that the company said to their product cuz it's just their marketing strategy to make people buy the product. However, you can achieve 9 hours MAYBE if you underclock the CPU and the GPU and lower the brightness. But your's is PERFECTLY FINE my friend. Hope this helps. Don't forget to click the thank you button if this somewhat helps you get an idea.

Haveing bad Battery Life? Read this.

Hey people,hows it going?
I have decided to create this thread to help people who arent very happy with their battery life pre/after the 2.1 update.
Aighty guys lets see : The improvements in 2.1 are VERY awesome if you combine it with things to make it total ownage.
Battery Life : Mine lasts 12h with very heavy usage, without usage it can last more than 48h...
Updated since sunday night so i got more than enough experience with it.
If you got bad battery life you can do followings :
1)Root + SetCPU : Lower the "Minimum" quantity so the CPU would idle very lowly and so you get more battery life ,i reccomend getting 245 there (This phase can be dangerous,if you dont know what you're doing ,skip this one)
2)Use Task Manager Pro : Shut down apps that eat the RAM, those who say "unused ram is wasted" , imo thats false as if you got more ram free : More battery life,better phone usage,less lags,and more space in case updates of twitter/fb etc come on ,i usually got around 105mb free always left (Excluded updates for social's & news & weather,live wall,android apps and stuff that i really need)
3)Still not fixed? Get a Battery-life-saver launcher and replace the Home one,as SE didnt work 2.1's home to good so its laggy and battery-eater.
4)Widgets?Have you got loads of news/updates widgets or apps? Try to lower the "Update rate", facebook updates as default each 5 mins,set it to around 2h or so,you dont need less than that.
5)Still pittyful? Check how much you use it, if i use my phone alot i get maybe less than 12h of battery life, but if you use it just the necesary trust me,you can get up to 3 days straight.
Battery life also depends on how much you use it.
5.1)Games specially can use loads of battery,so if you get a use of about 25% in 1 hour,thats very good battery life,so its normal.
5.2)Temperatures in battery can also go upper as you use it ,cause apps and your hand behind the phone cause heat,so you're alright if temp go up to 45ºC,which would be the safe limits. I would panic if it went up to 50ºC.
6)If you have just updated to 2.1 leave it a few days,it is quite bad at first as the system needs to update all its settings ,all its new stuff,just like when you install a new OS on a computer,it needs to "Start windows for the first time".
7)If its still very bad,then your battery might be damaged,get a new one and remember that the first 2-3 charges to take at least 8h,to make sure its lifespan is gonna be high.
In conclusion : Dont just say "My battery life sucks now", Battery depends on how much you use the phone,on how much your apps/timescape/mediascape/Social feeds/News feeds use your phone as much as gps/wifi/bluetooth of it.
Check everything you can,do everything i said and then see if ur battery is damaged or not,cause the 2.1 system didnt do worse,it actually did better than 1.6 after its perfectly settled.
Hope this helps out,take care ^

very good writeup, which launcher do you recommend?
in regards to this i believe you but it's just not happening to me
please suggest something.
my battery is awesome on standby....but as soon as i turn screen on and play for eg angry birds for 1hr it drops approx 25%. is that how it should be?
no wifi bluetooth gps etc. live wallpaper is there but i also try w/o live wallpaper. i use task killer and kill off unnecessary things
the only thing i haven't done is root and reduce cpu speed because the phone should work quite well w/o me having to do that.
My temp goes up to 43 at times. is that normal?
what am i doing wrong?

So far , LauncherPro did a very good job for me,there are loads of stuff you can tweak there like even from 3 to 7 homescreens, as you wish,the less the more battery so,depends on which you wish,you can select.
Also Helix Launcher is very famous for beeing able to save battery alot, tho it hasnt got so many options like LauncherPro.
If its very good battery life your searching : Helix Launcher
If you're looking for a good balanced launcher : LauncherPro
Goodluck.

25% in a hour after playing? Yes that is normal as games stress the CPU and screen brightness to max, so yes after gaming the battery does suffer a bit.
Nah if you dont want dont reduce cpu min speed.
Imo ,charge the phone completely , then right after charging , play Angry birds for 1h again and check battery. Sometimes the battery discharges faster than other times (Depends on the charge of it, if its @ 95% it will go down alot faster,unlike if its at 30%,it will go down slower. Its just a battery theory that is accurate most of the time)
So check from what % you started playing to what % you've stopped playing.
Tell me the results then.
And then i repeat,make sure you reduce facebook/twitter/email "update rate".
(More time(once in 2h not in each 5 mins) = Better cause it will access the internet less so more battery)

I used to support it, till I opened my mind to those theories, so now I argued. With many reading and my own experiment, I would still argue that droid are doing best it could.
http://forum.xda-developers.com/showthread.php?t=777034
With my summary, without ATK could result in even better battery life.
http://forum.xda-developers.com/showthread.php?t=678205&page=10
Some technical statement about android memory.
HOWEVER,
To correct your statement, it's TRUE that leaving more processes behind could result in significant drain of battery, but this is due to CPU usage, not RAM.
So yes, Leaving some process which draining CPU power behind could give much worse battery life.
So IMO, it more depends on your background process, but I would say that in most situation, just leave the droid do its job
7)If its still very bad,then your battery might be damaged,get a new one and remember that the first 2-3 charges to take at least 8h,to make sure its lifespan is gonna be high.

You don't need that any longer. But it's true that the lifespan could be 'higher' after a few usage, but this is due to 'calibration', not the performance of the battery itself.
Imagine
real battery is 10%, android report 3%
real battery is 90%, android report 100%
so you are using only 10% to 90%, that considered 20% lose.
Li-po batteries ain't meant to be drain to the last, if you do thy won't last and you soon be needing to replace your battery, I would think that it is programmed to monitor the usage to not do that but the battery % that you see is not actually whats left on the battery itself.
I was reading a pdf ebook and the battery dropped around 35% in 2 hours :S
I'm running the battery test in the service menu at the moment to see if my battery is faulty.
I don't use a manager - i don't use setCpu and I can easily get 24 hours + since 2.1
I'm just saying .
I stream music from di.fm using wifi 8h/day.
My phone lasts about 4h so, i have to charge it 3 times/day
Now, i want to see tips how to improve this

good idea never knew battery test existed in the service menu =]
shall try it tonight
just have a look on the attached photo , i took the photo when the indicator was 15% , still i can ran the phone for another 2 or 3 hours .
I don't know for sure, but it seems to me that the display chews through more battery than before.
Could be that I'm playing games too much but I don't think so. I seem to get the same battery life on idle, but as soon as I do anything (esp. games or talking) the battery just seems to nosedive. Never noticed this before (I used to get two-three days depending on the usage now I'm down to a day or two).
I'm gonna try and do some tests over the next while (starting with flashing back to 1.6 and retesting that properly).
tipically, display (screen) accounts for 2/3s of the total battery usage
check the battery usage app (settings -> battery), you'll be amazed
then make a simple test:
reduce brightness by half and your battery will last A LOT longer
Personaly, I prefer to carry my charger than dimming the screen

Back,soz my internet crashed -_-
And true,the Screen uses 2/3 or even more, everytime i check it sucks around 75% or so if you use it alot.
Also @Cebees Yes thats true,thats why i sugested a task manager Cutting processes cleans ram memory but also cleans cpu usage.
True you can let the droid do its things but most of the time its not Droid who is eating the battery to death,its 3rd party apps which remain On even after usage (Like when you select a live wall and then change it,the other remains on and some walls arent very good optimized so ...if 1 Live-wall eats a bit of battery,imagine 3 or 4 ?)
Also : Gaming / GPS navigation And Wifi Navigating are the main and most power hungry tasks for a phone to do,so its normal that if you're doing any of those,the battery lasts like nothing.
One Tip : Always take ur charger with you Also take the MicroUSB->USB cable off your charger and use it while your in your car (Buy a Cigarette->USB adaptor,costs less than 10 quid) and then you can charge it while you're in your/your dad's car, that way you'll maintain the battery a bit more alive.
Also if you really think your battery just isnt up for your needs, there is a 3600mAh (Think its Called Mugen 3600 or smth)battery out there for the X10,it is kinda bulky but it doubles and some times even more the life of the normal 1500mAh Stock battery.
Btw,if you want to buy a new battery and a 3600mAh one is too expensive,try to get a 2000+ one...as there was tested that up to 1800mAh arent exactly Shiny,just a very slight (Minutes)improvement over the stock 1500mAh one.
As you can see,there's loads of things that can cause a battery life to be poor
So keep on trying ^^ Im sure it will all go great.
I charged mine yesterday at morning,and i still got 67% Today,so i believe i can manage a total of 3 days straight ...and i did eventually use my phone to listen to music,put some live walls and make some calls.
Also trust me...the Launcher does make a diference,specially if you get the Helix one...i used it and my battery used to manage up to almost 5 days straight (With little use).
Oh and @Cebees : I know that the 8hour thing isnt exactly necesary today , but eventhought they say its not ,i believe i've been told by someone who knows about this that its good for the battery to be totally maxed in the first charges and then left to total emptyness(if possible until phone shuts down or is about to) that way it does calibrate (As you said before) and it does also maximise its life (Technically,i could be wrong , but my always done that with my wife's and daughter's phone and they always worked like a charm and trust me ,my daughter cant get her hands off her phone -_-)

Something bothers me here. During your intro, you say with "very heavy" usage, you get 24 hours battery. Then. In step 5, you say that if you use your phone alot, you get maybe less than 12 hours usage. I dont get it. :-S

My battery life got worse on 2.1.
On 1.6 I would unplug my phone at 6:20 am and listen to music for an hour then I would mess with my phone a little bit between 7:20 and 2:15. Then after that I would listen to music for another hour while surfing facebook. By time I get home at 3:20 I'm down to 60 percent. But if I do that on 2.1 by time I get home I'll be at 30 percent. Also I have juice defender ultimate that shuts off my 3g everytime the screen is off.

AnTuTu Battery benchmak

Hi guys,
I've been an iPhone user for four years in a row. This year though, I bought HTC One developer edition for me and my wife.
Anyway, I've seen lots of threads on battery usage and stats but they reflect results that are dependent on each particular user. I felt like my battery is not lasting long so I ran AnTuTu battery benchmark test and got 457. I still have a week for the unquestioned exchange term, so if anyone out there had the same test could tell me his score, I would decide whether to return it or keep it. Cheers,
P.S. Skype was running on background during the test. I don't know if this benchmark software is clever enough to calculate that difference, but antutu was measuring cpu-usage/battery-usage so Skype shouldn't effect the test result. Advance users might know better of course. :fingers-crossed:

Oddly enough I have the exact same grace period so to speak to return my one also , I have also not had very good results with battery and I am considering returning it also , I even downloaded wake lock detector , gem battery monitor, to try and see what is keeping this phone awake, so far I have not been able to nail down anything, I was hoping not to have to worry about every setting , ie, WiFi,brightness, etc etc , my s3 outperforms my one by at least 30 percent , I'm finding the phone is not really going Into deep sleep the way I think it should , anyway sorry for rambling , when. Saw your post I was like uhhhh yeah me too , anyway before I posted I went looking for antutu battery bench mark and I can't find that app , do you mean antutu benchmark, and that app has a battery score I it somewhere....? I never used that app , although I am quite the flasher , sorry for rambling , but I saw on another thread that someone else was not getting Decent battery results and had to exchange there phone and when he did he got much better battery results , I thin its a software glitch , I was hoping not to have too root, to achieve better performance ..........nope other people chime in , I'm a very light user lately and I'm barely getting 3 hours of screen time and 13 hours total , phone is draining around 4 % an hour while off....
I have the one since friday, after the onex has driven me nuts for a year because of the sh**y battery.
I am absolutly amazed by the battery of the one, getting 4-5 hours screentime (watching hd movies and playing games) and still having 20% left

Edit Okay maybe i'm mistaken but in order to run this test i think you need to be at at least 95% and it must take a long time , i've tried several times but no good phone is on charger will try again ....................jeeze lol

International Galaxy S5 Battery Life

Hey guys
I have a brand new GS5 and the batterylife is nowhere close to what reviews say. Yes I get 20+ hours but that is only counting in all the hours I am asleep.
When taking it off the charger and just browsing the web on autobrightness inside in just under a hour the battery is at 79 percent while on wifi...
Also Android system is what consumes the most. How can I fix this ? I don't want to root it yet but if I must do that that's fine for me.
Also while sleeping the battery loses 12 percent in just 6 hours. This can't be right ?

bear in mind battery technology hasnt advanced quite as far as screens and connectivity has. we have bigger screens and constant connected wifi and apps.
you're not going to get all the battery life you want. under mdium use id say this phone is about 12 hours use
Yes I know that buy it is worse than my s4 and even moto g. It can't be right. I've owned the one M8 and it should more or less like that phone but it is not by FAR. I wish I didn't break my z2, that phone couldn't be sucked dry in one day.
All this aside : if Android kernel and system is using the most energy something must be wrong

ok let me ask you this then instead
how much battery life do you want from a device that has a 1080p screen, wifi, 4g and a cpu thats higher than a P4 desktop?

Let me say you this: that's not the point. Don't try to defend samsung because you like them.
To the point: this is one of their flagship devices and I know that normally it should last a lot longer than it does now. And to answer your question it should last almost as long as the one M8 wich has near identical hardware but a less big battery.
My xperia z2 with the same chip but an even bigger display that is brighter lasted at least 22 hours with 7 hours screen on time. Yes it had a 400mAh bigger battery but that doesn't mean that there should be such a big differencr in things like browsing the web. A 1 to 1,5 hour difference yes maybe. That being said I clearly have problems with my battery draining while I'm asleep.
I have owned two s801 devices and I know it is a really power effecient chip so it is not normal that I lose 30 percent after 1 hour on really low brightness. The fact that android system and kernel is at the top of the power consumption chart is also an inidcation that there is something wrong with the firmware. I tought someone could help me that has had the same problem by suggesting for example debloating the rom, installing a certain kernel, disabling a certain samsung app and so on.
So if you have nothing better so say please may I ask you to not respond so that this thread can be maybe somewhat usefull to other users
Root, takes of all. Touchwiz craps and change a kernel you get more battery life.

Hi.
So I bought S7E in September. I noticed a smudge on the screen. I sent it in for repair. They repaired screen AND battery AND usb connector, although the only thing wrong with the phone was screen. They also wrote that they updated the software (I checked and I have android 6.0.1).
So yestrday I got the phone back. Plug it in the recharger and restored it with the back up I made and played with it while it was charging so that I could fully adjust it like it was before.
Than I went into battery settings and it said "Learning usage patterns..." And I was like "okay, you do that"
This morning I woke up checked if it is till learning usage patterns and it is not. BUT it says that the "Estimated usage time remaining is 10 hours".
Now I found that a bit odd and bit low, especially since its a new battery. Before I sent the phone for repair I had like 22-24 hours of estimated usage time when it was on 100%.
I also noticed that most of time my smart manager says the phone has 75% RAM in use. So only 1 gb free. I think that before I sent it there it wasnt like that.
So any suggestions, ideas or anything guys?
I also attached some screenshots
Your battery life seems okay. Check how many hours SOT You get. Take a screenshot of screen battery usage when You have around 10-20% or just say how many hours You got. With a custom rom I get usually around 4-5 hours at most, but with a stock rom 6-7 hours. And on my device I have 1.2GB of free ram and after cleaning ram I get 1.7GB.
Your first estimation is going to be low especially after a new update. Give it a day or two . And don't clean your ram too often because it will get reopened again . (waste of battery ) . Your android system is using alot tho but thats normal for newer software.
Give it time to settle down a bit It will get better
So far it's been over 4 hours SOT on my device and I still have 50%. 8 hour SOT? COOOOOL! That's why I chose S7 Edge . Let Your device learn usage patterns. It really works! After 2-4 days Your battery life will be better than ever
Okay. I made some screenshots.
I dont know either why System Android is using that much.
Anywayw today I was mostly on FB and 9GAG. I am ill, meaning home in bed. So I didnt really watch videos or talk on phone to much (maybe 3 or 4 calls).
Yeah. I hope it will learn my usage patterns and that will be it. Because sending it back to that company that repairs samsung here in my country is really the worst. Like they are retarded or something...
Will it also get less laggy with time? Because I remember that before I sent it there, it ran a bit smoother. Now sometimes when scrolling through this forum or facebook its a bit laggy... I know it wasnt before.. Is that also something that the phone needs to learn and adjust after few days? Or should I factory reset it, just to be sure?

Your sot isnt too bad for a new firmware. Atleast you can get around 6 hrs sot. Your lagg prolly wont adjust and i am not sure why your device is lagging at all. Give it a few more days. Just hope nougat will fix your problems and ours.
Well before repair I sometime got like 4 hrs SOT, sometime 5, sometimes 6, sometimes even 7. It really depends on what I am doing on the phone.
Well its not that laggy but I remember it wasnt as much before.
Do you maybe know when nougat is coming for s7e?

How can you activate this 'learn usuage patterns'? Is it in your battery settings? Could you please help?

The beta program is around the corner, its only a matter of time before it reaches out publicly. My advice to you is to turn off fast charge because for me its around 3-5 c less heat and it is only 20 minutes slower .

Hi, I'm experiencing the same problem the OP is. When I do a factory reset it's not saying "learning usage patterns" as my old phone did. Can you tell me why? thanks.

part 2 fine tuning the battery.. 7 plus hours SOT

This should really help your screen on time note 20 ultra
7 hours should be the minimum out of the box for a very expensive flagship handset.
I have tweaked pretty much everything and still get around 5.
Emailed Samsung today for a return. Useless handset.

Ever think that maybe you've got a screen time problem? If you're on your phone for 7hrs a day it's time to put the damn device down [emoji1787]

It's not per day, it's per charge. So if you're only a moderate user 7 hours ST should give you a couple of days. My phone boots up at 7am and is dead by early evening.

My phone does 2 days easy if I'm at work. Otherwise, sure I probably have to throw it on the charger around 5ish because I've been facebooking and reading the news, I'd say it's far from useless anyways. And while I'm at work in usually using the Galaxy buds to listen to my podcasts [emoji1745]

It's kind of weird how a lot of people on Exynos versions are getting seriously bad battery life.. The other day I asked my daughter to watch all of her shows and stuff on YouTube on my Note 20 Ultra and asked her not to put it on the charger for any reason because I wanted to see what kind of screen on time I could get and I'm seriously getting close to 15 hours of screen on time and I am posting pictures below so people don't think I'm full of it.. At 24 percent battery life left it said I still had a little over 4 hours left and the total screen on time was 10 hours 37 minutes so if she had stayed awake for another few hours it would have been around 14/15 hours without a single charge!
I stopped worrying about screen on time 3 devices ago. Just use your phone normally as a normal person.

That's easy for you to say but some of us have to work and we can't be near an outlet all the time and we need to know exactly how much time we have available for doing important things.. Also, people who worry about their battery life doesn't make them "abnormal" like you're low key saying (Just use your phone normally as a normal person.")... It's great and all that you don't care about your battery life but this website is for help and other things so if you're not going to offer any solutions or anything of value then maybe you shouldn't say anything!
The main issue is that most of us (some long time Note users) are buing the phone because it is considered a powerhorse phone and advertised with a battery that "lasts a day". Most of us are using it like a normal person, that is one that use the phone in his/her daily tasks from browsing to mails, chats, watching videos or shooting photos or editing documents. Because THAT'S why we bought a Note and not a...dunno iPhone for ex.
And seeing that battery isn't in fact lasting a whole day on a 1300 phone we're "a bit" disappointed (and I was extremely polite saing that)

Seems Samsung is catching some heat over it's two chipset variants... again.
They need to stop doing this two chipset crap... Samsung is more fragmented than an old lady's Vista desktop.

Nice move, pay 1300 bucks for a smartphone and don't use because you want it's ****ty battery to last...
Still, the battery drain will destroy your battery, specially on exynos version
If you're on your phone for 7hrs a day and most people average 8hrs at work (obviously you use your phone at work) that leaves you 9hrs plus an hr or 2 (because your using your phone at work a bit) left to get home, cook, eat dinner, cleanup and sleep, I'd say your wasting a lot of your life. At this point the damn batteries have gotten good enough I'd say [emoji1787]

The Exynos 20 U is far faster than my 10+ with better ram too.
My 10+ was running hotter than the 1 ton deep fryer on the USS Missouri at one point.
It will take some time but you can get it running cool.
Nominal idle current should be about an average of 150-200 ma. Otherwise something(s) is dragging it down.
Get PD MDM and proceed... you will need to develop a good level of proficiency before you see lasting results.
*Bah-ha-ha-ha*, excuse me, I meant to say fun times are ahead
One reason I refuse to migrate to Q is I put some serious time into this system to get it optimized.
This 10+ was a real wanker... sure the 20 U and Q will be "better".
