Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?

I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.

Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.

This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.

I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU

This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though

when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.

Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.

Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....

Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.

i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.

If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).

W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....

What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.

At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

Higher battery draining after 3.2?

Hi
I do nont know but i have strange feeling that after 3.2 update my transformer drains more power. I mean the battery is draining faster than before the patch? Have you noticed similar thing? (i do not have the docking station)

I seem to be seeing that as well, and the wifi signal seems to be weaker. Not sure if I want to put in a problem report.

Wifi signal is weaker for me too, but the battery's been just fine.

I noticed also that the standby battery wasn't as good on 3.2 for me compared to 3.1. After messing around with the device for a while I found that even when the battery saving mode was checked, the keyboard wouldn't wake up the transformer but a touch of the trackpad did. I thought that there might be some background service that was stopping the transformer from going into deep sleep so I used advanced task killer to kill everything and the device would go into deep sleep. Also, I read on another forum that it might be a syncing service for picasa. I turned that off, killed everything using advanced task killer again and battery life now is equivalent to what I got in 3.1.

I feel my batterie last longer. But I have to measure it first.

I've done some (informal) tests, and I'm getting about .5%/hour consumption on standby after 3.2, where I was getting about 2%/hour consumption on 3.1 and earlier. This is just the tablet, mind you.
So, 3.2 has significantly improved the situation for me. I haven't really measured in-use as closely, but it seems pretty much the same (which is about 10%/hour consumption if I'm really using it).

+1 same here

My Wifi is very good
The battery is good

My wifi has improved by a bar and the battery seems a little bit better. But that's only if I don't struggle with trying to get on wifi.

Maybe during use but if anything my standby time is longer.

Battery seems the same to me, as does wifi.

That has been my experience also.

After 3.2 mine seems to be draining the battery quicker with wifi on & surfing. I might get 4 hours of continuous surfing if that.

Me too, last night I have 95% of battery before switch off to the standby mode (screen off with the wifi sleep), but this morning TF has just 72%.
I am now testing it. I switch off the wifi function first, then switch off to the standby mode.
My friend also notices this problem after upgrade to 3.2...he said 52% to 17% just one night sleeping...wow...what a unbelivable report!

Look at the battery use reports on your settings and see what is taking up a good chunk of your battery life besides screen and wi-fi and you may find a problem. For me, I saw that Google Maps took up 25% of my battery and I only used it for five minutes (it said that it was on for over two hours). I tried force closing and nothing worked until I uninstalled the updates for it and haven't turned it on. Now my battery life is much better. You may also want to check applications that are turning your wi-fi on to update themselves, like e-mail and facebook apps, etc.

Check for Google latitude. It appears to keep GPS running even when TF turned off.

I am on 3.2 since yesterday (Belgium) with B6 dock.
Fully loaded and half a day later in standby 63%.
On 3.1 this would have been 83%.
Battery drain is much greater on 3.2 on my TF!
(Damn, I hate the keyboard lagg whilst typing this)

Mine has been better since the update and I have the ****ty B4O dock. I charged mine on Sunday then went on vacation with it Monday, on way home now and only charged it once on Thurs one the dock finally drained and the tab was down to 60%. Seems like they did something to help as that was unseen before, I had to charge it daily.

I also notice faster battery drain after the 3.2 update.
when I went to bed last night: Tablet 97%, Dock 72%.
This morning (about 9 hours): Tablet is the same, Dock 30%. WTH???

I noticed it today. I leave my dock on the Transformer even when its off and folded. I used it a few times to in the span of 2 days tying into a journal. Today the dock was at 3% Screen at 98. Im guessing its feeding power to the screen. The only settings i have different is screen always on. I shut the screen down when im done using it, or set the Transformer aside or off.

Very curious quirk On Android Open Kang Project ROM... Near Unlimited Battery!!!!

hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it

as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full

Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left

so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!

MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?

I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.

This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.

What's your battery life like on your K1?

What's your battery life like on your K1?
I get roughly 30 minutes every 5%.
And you?

I get roughly 30 minutes every 20%

1h every 10%. That's rad!
I get like 9 hours with 100% normal usage watching 1080p vids, surfing (no gaming!). So approx 11.11% to 15% per hour. When gaming I get like 3 to 5 hours with 100%. Thus for gaming you definitely need a powerbank!!

Anyhow, the battery stats seem to be very inaccurate (under Lollipop, dunno about buggy MM). I may install a better battery app and crosscheck.

Is the MM update for this tablet still suffering from battery drain? Yup

What do you mean with "battery drain"?

Battery drain

Been using the phone for a few weeks now and getting reasonable battery life on default settings. Probably over 6 hours sot (i don't game). However, during the night-time with wifi and cell internet off, it's draining at 1% or over per hours. A little concerning, as my 6T was probably half that. Has anyone tweaked any settings or used another kernel (I'm on global build) to achieve a better standby battery life?
Thanks.
Edit: looks like it's back to about 0.3%/hr idle drain now, so appears to be fixed.

I'm facing same prob with you, how did you fix it?

I think I just let it settle, nothing special.
