I love Android :3 - Nexus 7 (2013) General

Battery drain with or without wake lock, doesn't matter. :good:

It has nothing to do with Android, on average i'm getting 3days with 6-7 hours screen on time on every charge.
So either you have app that drains battery or your battery is malfunctioning. (or both)

Well, I don't think it's an app that is draining battery as, there are no wake locks and I don't use apps that run in background except Google apps. I don't think it's a hardware error either because this doesn't always happen. It started to happen a few days after I got the Nexus 7 half a year ago, then stopped and started randomly. It hasn't happened for at least 2 or 3 month until one week ago.
I also own an Android phone(a Samsung Galaxy S2, I know it's old) and wake locks happen so frequently, sometimes I wake up (after only 6-8 hours) to my phone having discharged completely. Betterbatterystats shows wake locks on my phone most of the time but they are so generic and not attributed to an app(i.e show up in the partial wake locks tab) that I can't troubleshoot. And why do I always have to troubleshoot? Why would I have to turn off all services to ensure I get through the day with 1 charge. I don't even use my phone a lot.

Let us see the BBS logs for your phone.
About the tablet, flo has never had good idle drain, but this is likely a problem with your wifi. Before you go to bed, turn off wifi and reboot. See if you can still reproduce the 3.0%/hr drain.
If that doesn't make a difference, recommend trying stock ROM and especially kernel.

Is he using a NON standard rom and the guy is *****ing about battery problems LOL

One word of advice, regardless. Do not let your battery drain completely. Ever.
Lost my Nexus 7 like that, the battery life is great so I was lazy to enough to charge it before going to sleep (it was on a very low level then). Got a thin brick in the morning

Charge it before hitting 20% battery to be safe. That is what I do. It expands battery life longer for me

Is this a confirmed phenomenon? I hear a lot of people say it's a fairytale and some people swear it works. Any official links confirming it or anything like that?

It does work besides there is no damage if you let it die just a few times but if you let the battery discharged till it dies frequently then you are damaging the battery. This is more common on Li-on battery as they drain more quickly overtime due to frequent loss of power.

Battery life sucks?!

So last night was NYE. I took my phone out with me and the battery was at 100% according to Touch IT ROM.
I took 4 or 5 pictures which were terrible, the camera sucks.
I stayed at a mates and woke up this morning, the battery was down to 20%?!
I haven't even used the phone and after 16hours or so the battery was nearly dead. What the hell, am I doing something wrong.
I always thought the battery sucked but this is a joke

same here ill try to get a new one
Check if you have any applications running in the background. Do you have Wifi turned on, bluetooth? Every module that is enabled keeps sucking power. If you don't turn them off, your phone can indeed get drained pretty quick. The battery is just fine, 1500mAh isn't bad at all. Do keep in mind that - due to the big screen and many options - phones like this just don't last for a week.
Also, did you fully uncharge your battery when you first used the phone?
If the problem persists, you can always contact SE to get a new one, as it's not supposed to drain that fast.
I know on the old P990 if you didn't exit the camera app correctly it just ran in the background and drained the battery. I do a double check in the task manager every so often to ensure that nothing was left running that shouldn't be.

I am testing this now on my X1 because I am alos not happy with MY battery life.
dingolino
the camera is not that bad, actually it's one of the bests I seen in a mobile device... anyways, don't expect to take, for example, good night photos, but actually, with good lighting the photos came really nice.
as for battery; I'm sure you shoudl have something (maybe wayfinder) running in the background, with moderate use I get 3-4 days of battery without problems; and I never let it get down 40%.
i get about 2 days max on my battery. thats with nothing running in the background, althought it does ckeck my emails every 15 mins.
shame u cant buy a bigger battery like a 3000 that would last twice as long as 4 days on one charge would be amazing
Hm.... i have another one for you guys. I was using the phone non stop for the past couple of days. Wi-fi is always on and i watch media and use opera a lot. The battery lasts for about 8 hours. When i got the phone the battery was almost dead. I did charge it but for a couple of hours only. Then i charged it overnight for 12 hours. Did the fact that i did not charge it for a long time from the box affects my battery life???

yeah, i did that with a phone i bought about 2 years ago and had to get a new battery as the original one would die after a day or 2 (should last about a week as was standard phone). i always leave a new phone on charge overnight now so i know its charged all the cells
I'm not going to say that you guys are wrong, but...
This phone, does not need to be fully drained the first time you use it, nor does it need to be fully charged. That was only an issue on older batteries, it's not an issue anymore.
I also believe it says so in the manual somewhere So, I'm guessing you guys had some defect batteries, cuz it's not an issue with the battery thats in the X1.
are you using Itjes latest HD based rom?
I found I got really bad battery life out of it for a couple of days till I let it run down to under 10% then charged it again. It's working fine now.

I heard the same thing from a couple of people. Older batteries had that problem but modern ones don't. I just wanted to make sure =P
u might be right. like i said it was about 2 years ago it happened to my phone. but why take the risk
The only thing I had on was wifi and check mail every 30minutes.
I only use general useage (8 pictures and a few messages)
but that was it. I dont understand. I charged it for 20mins and its gone from 20% to 60%.
7hours later its only on 50%. Strange thing is, my phone has been on a radiator all day and it hasnt last that much charge.
Last night it was freezing -4c outside and wasnt that warm inside, then I slept in a cold room. I wonder if heat has anything to do with it :S

Did you flash your phone recently? was the battery at full before you flashed it? it's been reported as a problem on other phones (I remember the UNI used to do this) that if you flashed when the battery wasn't at full it messed up the power levels.

Mine was crap the first few days. I read somewhere on this forum to run battery to zero and charge overnight with the phone off. Mine now lasts all day and is recharged each night.
Just a sidetrack with regards to batteries...
When I charge my X1 with the device turned on, the battery tends to heat up till even the casing is hot to the touch. Is anyone else encountering the same thing?
However, when the device is off while charging, the battery doesn't heat up.
Weird...
It depends on what applications you've installed.... Touch flo drains it like hell.
My phone looks like this.
I use SE panel 1, no other gimmicks.
Pocket player for music 2 hrs each day.
15 min of video here and there.
2 hrs of phone calls, and a hell a lot of messages, which means keeping on switching the phone from potrait to landscape and so on...
SPB phone suite.
SPB wallet.
SPB Wireless manager.
I get a solid 2 days with about 15% remaining at the end of the second day...

As much as possible put the phone in sleep mode when you charge the battery. And the battery gets more heated up when charging over USB.
Hi!
I had the same problem some days ago. Even if the X1 slept on my desk with no application running, after 2 days the battery was empty.
I thought about what I installed last and deinstalled Batti. And now the battery lives much longer.
Btw... does anyone know a good app to show the status of the battery? Or how I can show it instead of the clock?
Batti was great but charging every second day was not.

X10 Power Usage

Hey.
Got my X10 a few days ago,
And im the only one with a power problem ?
Having to recharge it alest once a day ?
My batteri drops aprox 12 % per hour, so I usefully charge 2 times a day.
Since 1AM to now (12AM) it went from 100% - 24%. And Ive been sleeping alot, so the phone hasent been muched used either.
What kind of usage are you partaking in? In my experience most smartphones have to be charged daily.
Here's a post from Esato Forums where someone did an extensive battery drain usage test:
http://www.esato.com/board/printpost.php?post=2933402
The last day Ive been using it minimally, and Im on my second charge for the day. All my other phone last 1 day (6am-12pm) before needing charging. But my X10 needs an aditional charge at about 2-3pm..... And even then is as good as empty at 12pm....
I hope its just a small software bug, or something that could be fixed with a reset. Im starting to enjoy this phone, but there are several days a week, I will not have the time to charge it a second time..
Think Ill go for that reset, and see if that helps....
Anyone else with X10, and batteries that drain extremmely quick?
Mine dies after about 8 hours, but this is usually normal with new batteries, it should be better after a few FULL recharge cycles.

Were your previous phones smartphones, just out of curiosity.
Also, you could try to reduce how often TimeScape polls in the background for updates. That might help.
My current iPAQ 910c lasts a full day if I do nothing but the occassional phone call and SMS. However, if I do anything power intensive the battery fails, and the phone is done until it can get 2 hours or so of charge. But that's why I'm looking to replace it... definitely not normal.
I have access to every phone I want.. And Ive only been using smartphones.
(Currently as in sign.).
I dont use timescape or mediascape, so they have been disabled.
And yet the battery only last for aprox 10 hours....
I never had a phone with such a bad battery, however, Ive never had a phone with such big screen or cpu either....
You gain some, you loose some.
And to he who talked about recharging cycles to maximize battery,
this kind of batteries dosent work that way... They are allready maxed..
I've had mine for a few days now.
The battery's pretty good, I've only charged it once over about four days, so I'm pretty pleased. However, it does seem to use a lot of power if you have wifi on, even in sleep mode.
I've also had no problems with my "a" in either keyboard (Norwegian/Japanese) so far.
I'm still on 14 btw, if anyone's noticted battery dropping after they updated.

I would not say that the my battery is good. but it is ok, i haven't had it fully charged yet, since I did get git yesterday. and it did last about 10 hours or so, from 60 or 70%. with playing music, trying out some things etc. but I worked 5,5 of these hours and was in the movie theater 2 of the other hours.
anyways, I haven't really had much problems with the keyboard either, as you said. the only thing that really buggs me is the damn space button. it is too small! :/ I wen't from an X1 to the X10 no, from using HTC magic before that. But I am starting to get really used to the other keys.
I haven't installed the latest build/patch either.
//
Just download "spare apps" and see what apps som drain u battery
My X10 take only 6% on 3 hour on normal use
very very bad battery drain! Left mine on flight mode at 2AM with 50% battery left, before going to bed. Woke up at 11AM and the battery was dead with no usage nor cell connection!

A chellphone uses more battery when there is bad reception, because it tries to get a better reception.
Like if there is just edge, the phonei strying to get HSDPA connection instead, this drains more of the battery.
+ With android the phone leaves some of the apps running in the background.
I recommand that you get an app that can shut these down.
Like a task manager kinda..
eg.Advanced Task Manager
I hope this helps ye.
and if you go into "settings - about the phone - Battery usage" then you can see what apps that is draining the most of the battery etc.

As I wrote before, phone was in standby on flight mode: it means that NOTHING was running nor any 3G data was exchanged. I've had many Android phones (Magic, Hero, Milestone, Nexus, Legend) and in similar conditions they lost only a couple of percentage points of battery, not 50% like X10!! I do love this phone, but heavy battery drains is driving me crazy (and it's definitely not a faulty phone, since I know many many users with the same problem)

I actually think the battery is good too. I recharge every other day, which seems to work fine.
I have bluetooth and wifi off, and mostly doing manual updates for timescape. I do surf quite a bit though, and no problems with battery drain. In my experience, my X10 lasts a lot better than a Satio for example.
Strange how half of the people posting here, have very good batteries (1-2 days), and the other half have extremmely bad batteries (8-12 hours).
I doubt the ones with the bad batteries are "worse user" then the ones with the good batteries......
I'm one of those with lousy battery usage. Hardly use the phone, but drains in no time. However I've ordered 4 new batteries, so gonna test all of them and see if there's a pattern.
Grrr.. Was just setting up my contacts to Facebook.. Took around 20 minutes and drained 21% of my battery.. That's just not okay..
I just left it for 2 hours without doing anything and the battery from 90% dropped to 65%. This is not cool at all. SE we need a solution ASAP.
I'm one of those that get bad battery duration on the X10. I usually leave BT and WIFI on as I did in my N97. By observing who drains most of the battery, I get around 30% for the radio in standby and 20% for BT. The processor is only a small percentage (2%) so I don't belive that the snapdragon cpu can be blamed for bad battery duration. How is it possible that Nokias as the N97 having the same communication hw (GPS, WIFI, 3G, BT...) last for days with similar usage and battery capacity? Ok, the procesors are ony half the speed but I don't belive this makes so much difference...
I own a HTC Nexus also and has slightly better battery duration than the X10 but way far form the N97. I've roorted the phone and can change the CPU speed. It makes very little difference on battery duration if you set 400 or 300MHz instead of 1GHz.
So, it seems what makes all android devices so power hungry is the way the OS handles the communication interfaces, I belive most RF chipsets should have similar power drain and CPU's are idling most of the time. Perhaps symbian has a smarter algorithm to hanlde 3G/GSM/WiFi switching and no services polling the network when the phone is in your pocket.

Horrible Battery Life after Installing Android! :(

After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .

Battery life amazing now. Why? You tell me.

I have had the ultimate in crappy battery life since day one with my Vibrant. I have tried reconditioning, task killers, freezing apps, etc., etc. Very minimal gains and, in some cases, worse battery life. These things were draining just sitting on our pockets.
Here's where it gets weird. My wife also has a Samsung Vibrant and was getting the same horrible battery life. We were both charging dead Vibrants half way through the day. Granted, we are both moderate to heavy users but I expected more. A week ago, my wife was still sitting at 80% by lunch time while I was looking at 27%. Huh? I asked her what she did and she had no idea except that she had downloaded a battery monitoring app the day before. I thought it made no sense that this could have anything to do with it so I brushed it off. Over the next few days she was still getting killer battery life throughout the day.
So....I decided to give it a shot just to be sure it wasn't that app. Well, just before bedtime, my battery was it 7%. I downloaded the battery app, plugged in my Vibrant and hit the hay. By noon the next day I was still over 80% I have no idea why but I know it's working for both of us and it has to have something to do with this app.
I'm no programmer and I certainly have no vested interested in any android apps. We just stumbled on this and it works. Would anyone out there have a clue why?
I'm not sure if posting the name of the app breaks any xda rules so I'll wait.
Ever since i've been on JK2 Froyo my battery life has been excellent. But i'm interested in hearing which app you're talking about

I agree. I just didn't want to be seen as peddling a product here.
It's called BatteryTime. It's free although, I believe there is a pay version. I didn't adjust any settings. Just installed it, charged over night and I can't believe the difference nor understand why it made such a huge difference. I unplugged 4 hours ago and have 98%. Still a mystery to me but I'm not complaining.
There's like 4 of the same app on the market x)
What is the full name?
OH and thanks, I installed it, I'll report back with results.

Just Looked again and you're right. There are 4 versions there. I'm currently using the "BatteryTime Lite" version.
The only thing that I can think of to rationalize this huge difference is that the battery percentage was being reported incorrectly before. I may have had a charge that would last all day or longer but it was displaying an accelerated discharge rate which would kill my Vibrant prematurely. For one reason or another, this app appears to have corrected that and the indicator is (I hope) reporting the correct battery life now.
Does that make any sense?

Thanks for sharing. I will give it a try.
Update:
I found this somewhat disappointing. I rebooted my phone for the first time in about a week and on boot up the indicator is displaying significant drain again. I was at 96% before boot and 56% after? I'm going to recharge to full again and see if I still enjoy the same battery life.
Now I'm really confused. Sent an email to developer.
judging by the app description and most of the comments - the app doesn't actually *do* anything. It merely reports the battery differently.
No amount of software will change how much charge a battery can hold. The only thing that's different is how it's being reported.

Indeed, and that was my point to begin with. Originally, the battery indicator reported as critically low in no more than 6 hours. Soon after, the phone would shutdown until put on the charger. With this app I am able to get through the day reporting roughly 30% at bedtime around 10pm. Of course, that is subject to change on a reboot....until fully charged again. This is the mystery.
Yeah, there is funky stuff going on with battery meters. One that is included with the Obsidian Roms is Battery Left, currently, this is showing a 50% charge and 10:19 left. Next to it is Juice Plotter which is showing 21h 11m left. According to the system, i am at 71% Power and it has been unplugged for 6 hours. From experience, I know that the 21h remaining is actually accurate and Battery Left is completely dorked.
The point being, you can't always trust the battery meter.
So I installed a monitor also to try and figure out what was killing my battery 30+% over night and I had the same reaction....I woke up to a 10% loss. I realized what is probably happening is since this app is monitoring the phone all night...whatever app is draining the battery is probably a daemon that only runs when the CPU goes really idle for a certain period of time. More than likely that app inadvertently gave you better battery life because it runs in the foreground and marks your phone as being active so whatever app was killing battery never ran.

I think you've hit the nail on the head. Since day one, I have had buggy battery reporting. For instance, if I reboot the phone while it is plugged in, the reported battery level changes dramatically.
Edit: your later post supports this idea even further.
I installed this on my phone. This program does not attempt to save battery life or control anything on your phone. It does offers "Tips" to save battery life. Its main purpose is to indicate, based on your current level of charge, how long your battery should last given different circumstances - ex. idle, talk time, video time, audio time, etc... Thus the name BatteryTime.
That's all that it does. Any perception of a longer lasting battery may have been an anomaly as does happen sometimes with our phones. One day you'll seem to be getting awesome battery life (and there is likely an underlying reason which we'll never figure out, but which jives with the battery) and the next day it is back to draining quickly as normal.
There are three certainties in life: death, taxes, and posts about battery life in smart phone forums.
Anyone have the issue where they charge the phone overnight, the phone reads 100% in the morning, you unplug it and you are immediately down to 7% battery? It seems to happen to me at least twice per week. It is a terrible bug.
i dont get it you said that before the battery wasnt being read correctly so it shut off fast but now with the app it reads correctly and last you the whole day with 30% left to spare?? wouldnt that technically mean it increased battery because you got it to last all day plus some? just by making the phone read the battery correctly.

98% deep sleep but 48% battery drain? What gives!

I charged my phone for a little bit last night because it was a little low (48%). I took it off at about 77%. I don't understand what happened. Why did it just drop like a rock? Phone is AT&T LG g2, stock 4.2.2 rooted.
Jesus that can't be good.
I have no clue about this one; it's just too weird.
I'd probably let it fully deplete and then completely charge it and see if it ever does it again.

That's what I'm going to do. Unfortunately this is not the first time it has happened. This happened about 2 weeks ago, but then my GSAM showed a HUGE signal decrease at the same time my battery drained, so I figured it was just that.
This time I just do not understand. I've had this phone since August or September and it's been great until this randomly started happening in the past couple weeks.

Well it says 66% of that was phone radio signal. So that is the problem 90%. I had similat problem only it was while charging, so my phone wasnt charging almost at all, when i restarted it was charging fine (from 20% to 100% in 90 min) . What happened when u picked it up, was it still doing that? Or maybe its a some kind of cpu loop if that is even possible. Some people was complaining about nexus 5 rapidly discharging with combo of some lite apps (news readers).

Yes even after picking it up, the drain continued. I've let it die and am charging the phone while it's off but I don't know if the problem will be fixed.
The youtube app was causing a major battery drain for me a few days ago,now I close it after using it just in case . I'm in the habit of checking the phone's temperature at all times :/
it has a great battery life, especially sceen on time, but the standby isn't top notch at all, I think it's poor software optimization on LG's end, I hope 4.4.2 fixes it.
charge till full. then reboot and check battery percentage.
