[Q] Suddenly Nexus battery drains quickly

Hello all.
I bought a Nexus One in at the beginning of the year. It's not rooted and I've had no problems from it till this month. I can not say the timing is exactly this, but it seems the battery issues started just after the FRG83D upgrade. I am accustomed to using my phone for most of the day before it needs to be charged. 12 hours or more with moderate use. Since around the FRG83D update my battery is about dead in around 4 or 5 hours. I haven't changed any settings or gotten any new apps or anything for quite some time.
For example, Friday night I charged my phone to 100% and then unplugged it (to plug in my girlfriends phone) and went to bed (about midnight). At 5:15am my alarm went off, i glanced at my phone and found the batter was at 10%!! the phone had been sitting there doing nothing all night with the screen off. I checked the battery use screen and it showed cell standby and AKMD taking up all the battery (55% and 35% respectively). I should mention that I have full signal where I am and have never had an issue. I cut off the screen rotate in the settings just in case that was part of it (AKMD being the gsensor i believe).
At next full charge that day i noticed the same problem, after being at 100% my battery was down to 10% after about 5 hours, almost the entire time I didn't use the phone. This time "display" was the largest percent by far (followed by cell standby), but clicking it showed only 15 minutes of use time for the display as I had purposefully not messed with the phone much.
Last night I had to be out and a bout so I decided to test things again. Charged full and cut airplane mode on. about 4 hours later my phone was down to 20ish percent, the only use of the phone being me looking at the charge level a couple times through the night.
I installed "spare parts" app and it shows my battery as being in good health and such but who knows how reliable that is.
Anyone else having similar issues? Any suggested remediation measures? I'm considering flashing the phone and reinstalling apps and such but would rather avoid that having never done that before and not having a desire to deal with setting everything back the way I have it.
Don't know if it matters but I run LauncherPRO and I do use the friends widget but it's never seemed to really cause battery issues before. I also run the news/weather widget, but again, no previous problems.
Any help would be great
Thanks!

In the spare parts app check partial wake usage. See if any apps are not letting your phone sleep.

nothing stands out other than UID 10073 which is handcent. currently my phone is charging but I'll pop it off the charger soon and watch the battery drop time again. I should note that inbetween all the tests so far i've rebooted the device so hanging apps of any kind should be killed off...

What ROM are you using?

Are you using Extended Controls? There is an issue with that and FRG83D. Uninstall it until the dev sorts it out.

yeah i am using extended controls. i'll take it off and see what happens.

Me too
I Have exactly the same issue, also have extended controls. Uninstalled and waiting to see if that works.
Cheers for the suggestion.

That did the trick! Loss like extended controls was the problem. A shame as i really like that app. Will hope they update and fix soon. Thanks!

Extended controls updated!

Yup, uninstalling fixed it for me too. Haven't seen the update though. I remember seeing an update yesterday, but I had this issue with that update so that did not fix it for me. Hope they update it again soon

I think it was updated again today. Now v5.03, and it seems to work properly.

So nobody saw Extended Controls showing up in Spare Parts, System Panel or other such programs?

Battery drains quickly

Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?

There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.

What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.

Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.

Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

In most custom 9000 based ROMs, wifi is set to "never off" by default.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.

So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set

I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

[Q] battery issues - 3 charges most days

Hi everyone,
I brought this wonderful phone (or atleast i thought wonderful) couple of weeks ago ( delivered on release date)
Now i expected the battery to be good as its 2300 mah but it the phone doesnt seem to last no way near as long as other claim i had an s3 before this htc one, 9 times outta 10 i only had to charge it once a day and never activated power saver mode,
On the htc one i constantly have power saver turn on and it just doesnt seem to be doing anything , i havnt changed my usage of my phone, if anything ive used it less,
For example the s3 lasted my full 8 hour shift with nothing running expcept the tunein radio app, the htc one only seems to last 4-5 hours with everything closed except the tune in radio app. Ive not changed networks so low signal shouldnt be causing the drain as there isnt a difference in signal levels,
So is there anything else i can do to stop bettery draining. Bluetooth, wifi, nfc, etc all turned off, screen on auto brightness ,
Sent from my htc one with just 26% battery left and i havnt even rrached 4 hours of my shift yet, left house at 9:45 with 100%

You probably have an app preventing the phone from sleeping. There are loads of tutorials on how to check for partial wake locks to fix this.

Try this or this to detect the wakelocks. For more info on wakelock, read this thread

Definitely sounds like you have an app which is preventing the phone from sleeping and you should be getting a pretty easy 1 day out the battery at the very least in moderate use.

How have you TuneIn setup.
As general when you press pause rather than stop, itt continues to record that station and is always active. Iif you go into the app settings and turn off 'autostop recording' which should be defaulted to 8 hours - turn this to never and try again to see if it improves. I've seen TuneIn eat battery life on other devices where ths happens (people thinkits stopped when its just paused and recording away in the background...

That's possible ^^^^, however if he was just to hit exit on the app it should stop the services. That and really want to be sure, swype it away in the multitasking section.
Can try Betterbatterystats in the play store as a lot of people rave about that.
Also make sure Google Now is disabled. It sucks battery life like no other. Awesome tool, however to much drain on the battery.

Would be great if you posted a picture of the battery use. You must have a wake lock.

Guaranteed that you have horrible wakelock issues. Rogue apps, bad settings, and anything in between could be the cause.

I can go to bed with the phone fully charged and, 8 hours later, wake it up to see it's still at 100% (mobile data, GPS, WiFi left active.)
Once I'm bored of constantly picking it up and playing with it (i.e. get back to standard usage patterns) I get the feeling it will likely run to 3 or more days between charges. Won't be this month though

The Same happens with my phone.
The battery is really good. It feels like it is the battery time of my Onex x3

Well there are various reasons for this..Maybe an app that drains much battery not leaving cpu to sleep.You can download better battery stats and see the wakelocks and the cpu states that your cpu runs on.. You may also need a battery calibration.It will not increase the battery capacity of course but it will eliminate the faulty battery stats bin that tells the system the battery percentage.You may have for example 25% battery left and your device may show 2% or even close.
I assume that you do not have wifi always on, screen on for hours or using mobile data..The consumption of battery is huge.

how ? when u first got the phone ? did you turn it on or did you charge it?

Worth dialling *#*#3424#*#* and doing the battery test, although as everyone else has said it's more than likely an app.

I had a sgs2 over 2 years,rooted and optimized in battery usage, i was already happy. Now with the htc one it's a completely new experience....already now after a few days,with root but still no tweaks i get 60% left at 11pm!before the sgs2 was empty...can't wait
For fiture developement!!

Download Better Battery Stats, leave it for a day and then upload a screenshot of your wakelocks. My battery is easily lasting the day (ended at 11pm at 76% yesterday)

Same-ish problem.
Hey i'm having a similar problem,
I bought the HTC One (silver, 32Gb) A couple of days ago and the battery isn't even lasting a day with what I'd say as Medium/light usage. I do leave Mobile data on so i can get Skype/Facebook/line calls ect instantly, but i assumed that's normal.
I just left my phone alone for an hour with the screen off and it lost 4%, could this be a battery defect?
Are you telling me to get over a days usage, i have to leave mobile data turned off and only turn it on when i want to use Skype ect?
I saw a post above that one guys gets 3 days of usage with Mobile date, Wifi, etc all turned on. Is this the norm, or does he have a super hero battery?
I see the general consensus is to download "Better Battery Stats" and send pics of wakelocks, but Is there comparable app for free that will do the trick, as i don't have money currently on my English account.
Thanks to all those taking time out of their own lives to help others.

[Q] Help, please! My battery?!

Okay, so.. I have a Samsung Galaxy Exhibit II 4G.
I have it rooted with the root stock from this thread.
With that said, I've had this phone rooted for several months now. Since January or so. Over the course of that time, the phone has run without fault for months. Recently, I've had issues with my battery draining (as well as charging) far more quickly than it used to. I assumed this was an issue with the battery, because there was a slight bulge in it, so I bought a replacement battery that came yesterday. I charged it full (until the phone said it was 100%), from about 5% charge. It took the normal time (as the phone did when it was new) to charge, of just over 2 hours. It died almost completely about 2 1/2 hours later. Currently, I have my phone charging and it's at right around 90%, after just over an hour of charge from 20%. It used to take far longer to both charge, as well as die. What the Hell is going on?
Just a few notes:
This is not the result of heavy usage (for power drain). I say this because even as the phone was idle while I slept, it died on its own accord sometime throughout the night.
My bluetooth, WiFi, and GPS are almost always off, unless I'm using one of them for some purpose, and I haven't used any of those things since the new battery was installed.
There are no applications running in the background, aside from Facebook. I know this because I'm using Advanced Task Killer to kill everything, and it keeps showing Facebook as if it's opening itself for some reason. This is another issue I'm concerned with, so if anyone knows why or how to remedy this, I'd be appreciative of knowing. Otherwise I'm likely to just delete this unnecessary application.
This is not an issue where the phone is reading an incorrect charge over an extended period. It literally is dying and charging faster than normally.
When the phone is rebooted, whether it be through "Restart" (app from Google Play), via the phone Power key, or removal of the battery, the phone drops around 20% battery life when the restart is complete. The absolute reverse happens (it gains 20%) when restarting with the phone plugged into an AC charger.
Is it possible that this has something to do with the root being outdated, or maybe something updated and I'm unaware? I sincerely have no idea what's going on, as this is the first phone I've ever rooted before. I'm sorry for the long post, but I wanted to give as much information as possible.

It sounds like the battery you bought may be defective. Send it back and get a different one.

Yea sounds like you bought a defective battery. Where did you buy it from? Talk to them and see if they'll send a replacement or get another one from elsewhere

T700 Tab S Standby Time!

My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?

Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.

clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.

I flashed a whole new OS... should i wipe it?

You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.

Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.

So i wiped and its still 48 hour batter!

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.

Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.

How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.

disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.

Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day

Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.

i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?
