I had this problem once when I first got my captivate, but then it went to normal (lose ~5% overnight). Overnight I keep wifi connected and airplane mode off. I was happy, lasted 10-15 hours daytime depending on how heavy I used it, etc.
I recently ordered a two spare batteries with an extra micro usb cord as well as an external battery charger (charges batteries while not inside the captivate). I use the new microusb cord to charge sometimes too because for some reason it doesn't work with PC to connect micro sd card, and I charge my batteries mostly using the external charger.
I recently started losing 30+% overnight. I don't know when exactly (if it were apps or the new batteries, but it happens with my old battery and the new ones). I installed spareparts and battery history and tried turning off background data but I still lose this much overnight. I don't really know how to read spareparts to try to isolate an app. My daytime battery life is not drastically lower than before (10+ hours), but I think it is a bit lower than before. Does anyone know how to fix this problem?
tl;dr:
- used to lose <5% battery overnight
- got new batteries, now use external charger
- suddenly started losing 30%+ overnight, don't know why
- help please!
thanks!
I personally lose more than that overnight when I have wifi enabled. However when I have it off I lose less than 5%. So I guess I'm in the opposite situation as you.
Since you already have spare parts installed and used to have better life the only thing I can suggest is recalibrating http://forum.xda-developers.com/showthread.php?t=765656. Sorry if you have already done this before. It's just that when you pull the battery and switch it I'm assuming the battery stats file may not adjust accordingly. It's worth a shot.
I seem to be having the same issues as you. I made a thread over at the Q&A section which may be of some help.

As for losing more than 30%-40% overnight with wifi enabled, there has got to be some lingering issue on your phone if it is losing that much. I don't think any phone, no matter how bad the battery life it has, should lose that much overnight, granted that you don't have a TON of data intensive activities running on your phone.
30-40% WOW!
I get 36-48 hours in between charges on my phone.
Wifi is always on, sync is always on, no live wallpaper, weather and email updates every hour. I'm not on it every minute of every day but enough use for sure.
over night I lose about 5% on average.
Calibrate your battery...but you can't change batteries or you need to calibrate all over again.

As I posted in this thread: http://forum.xda-developers.com/showthread.php?t=829285, I did a factory reset and my phone seemed to be working fine as it slept when the screen was off (checked by using *#*#4696#*#*). It was good until approximately 50% when all of a sudden I checked and it wasn't sleeping once again. Checking the partial wakelock "Android System" was taking up an increasing larger amount of this section. I didn't do anything on my phone as I was sleeping and periodically, when I'd wake up, I'd check on my phone status. When I reboot the phone once this happens, it sleeps once again.
Keep in mind, my phone is stock. Didn't install any apps or anything at all since the factory reset. Now I'm not sure if I have a defective phone. Maybe the Android OS is set up to run like this? There's no such thing as a defective OS is there? Can't be anything on my end because I didn't touch the phone nor did I install any bad apps (or any apps at all for that matter). Can it be a battery issue? I can't see how a bad battery can cause the phone not to sleep. Is there something in the Android OS that turns on automatically after a while that may be causing it?
I'll try to recalibrate my battery but I don't know how that would alter if my phone sleeps or not, but I'm willing to try. I'd rather not take this phone back and get another one as that's a hassle.
Mine will loose 40% over an 8 hour window easy with absolutly 0 use if its near the "edge" of either wifi coverage or data coverage.
IE, sit the phone down with a weak att signal and walk away. It'll die on its own unless you airplane mode it within half a day.
I have to religiously turn the phone on airplane and switch to wireless at home, and turn to airplane and turn wireless off at work (can't connect to work VPN with 2.1 !)
If I leave it on full in either location, it's bloody dead next time I touch it.
However, with good home wifi, I can actually get 4 days of email checking, use as alarm clocks, some other sms stuff without plugging in.
This things is helaciously sensitive to wonky radio connections.
hmmm. I guess I'll try it with wifi on tonight. I don't think recalibrating would cause it to have a 10x difference in idle battery usage, but I'll try that if all else fails
I use Setting Profiles app and have it set wireless to Airplane mode from midnight to 6am. Still, I'm finding my battery down by 30-50% at night.
Looking at Battery Usage, my Display, Cell Standby and Phone Idle we all using the majority of the battery power. I'm not sure if these numbers are reset after the phone comes off the charger or how it is calculated.
I just turned off wifi altogether and have seen huge improvements. I don't even use it anymore despite being in my house with a wireless connection. Data usage isn't that much slower so not much of a loss. At least it can sleep.
i only get like 24 hours on my phone :/

It's not just this phone. My wife's iPhone does the same thing, as did my Q9H. The constant switching from 3G to Edge will kill a battery.

I turned off wifi and have seen an improvement. It's still not where it was before, though - I used to lose 5-10% with wifi on. I wish I knew what happened.
Is anybody seeing heavy battery loss during standby mode?
On average my TF is losing between 3.5 and 5% battery in standby mode. I have done a few tests with and with out airplane mode and it does not change.
I currently have an RMA setup with ASUS but I dont want to have to send it back and wait 14 days, so I wanted to reach out here first.
Thanks in advance,
Brandon
Every device I've ever owned has lost power during standby. That's the tradeoff. Otherwise, you could, you know...turn it off?
Windows has that nice "hibernate" hybrid.
It's totally not worth an RMA...don't let your OCD win.
There are a few processes that run in the background like Android OS, WiFi, keyboard etc. It needs to be reactive to certain signals so it can't be off completely. The iPad has amazing stand-by times but I don't know why. I just saw it when I borrowed one for a day from a friend.
I would NOT RMA my device unless it's a significant drop in battery life (>10%/h); it's just the way it is mate!
But what I realized is after I rooted, installed SetCPU and set the governor to ondemand the battery life has increased significantly. It idles at 216MHz now.
mine doesn't have a great standby time either, pretty bad actually when you compare it to my xoom. however its an issue that should be fixed with a software update and it shouldn't require an rma.

Check if you have your Wifi on sleep also?? Depending on number of applications that you use for updating it might be using your battery.
There are a number of other threads already discussing the issue of battery life in standby, but here's my conclusion: the TF has an issue with wifi that if you set it to stay on while the TF's screen is off (a setting in the wifi section of system settings), it burns quite a bit of battery while on standby. If you set it to turn off when the screen is off, then it doesn't.
I know this is a bug with the TF because the Xoom does not exhibit this behavior. It burns less than .5%/hour when on standby with wifi set to stay on when the screen is off. The TF gets this same performance (<.5%/hour burn) on standby only if wifi is set to turn off. Otherwise, I'm getting the same as you: around 3.5%/hour burn rate.
I'm assuming that the TF's wifi just doesn't enter whatever low-power state it's supposed to enter while on standby. My second assumption is that this is something that will get fixed in an update.

I just turn on airplane mode when I know it is going to sit, and it burns about 1% an hour.

Is there an adjustment for the Wifi and/or app settings. In general the second or third largest power consumer in these devices is the radios. The radio needs to be powered up whenever a connection needs data. This can be for keep alive messages that verify the existence of a wifi connection to an access point, or from an app such as gmail, calendar, etc. checking for new data. In any case there may be settings that allow one to decrease the frequency of these operations.

FYI, I did a few tests with airplane mode on and I was still losing around 3.5%-5% battery life.
I did do a few more tests, and my most recent test I found interesting.
I use my TF as usual and had a few applications running, I then turned off the screen and let it sit for an hour and 4% battery life was used.
Then I powered down my TF fully, then I powered it back up and turned off the screen. (Currently the TF is up and running but no applications have been opened aside from backround apps Syncing).
I put the TF into standby (turned off the screen) at 1:37 am and I had 53% battery life.
I checked on the TF in the morning at 8:51am, and I had 51% battery life.
So in just over 7 hours my TF only used 2% battery life in standby which is a very acceptable range.
Conclusion, what ever apps we are opening and using under normal use are not being fully closed out, and are running in the backround, not the backround services as per the airplane mode test.
I will do a few more tests tommorrow, I hope this helps and I look forward to others feedback!

Brandon - Please check out yours with wifi set to turn off when the screen is off. In all of my testing (similar to yours), that made the difference between great standby performance (<.5%/hour) and not-so-great (3.5%/hour or more). Nothing else seemed to matter, including manually turning off just about every app that normally runs in the background and verifying that they stayed off.
Hopefully soon Asus will also fix the battery stats bug so that we can see what apps/system components are actually using power on standby. Or they'll just fix wifi so that it sleeps as it should.

I have already done the tests with WIFI turned off and also with the TF in Airplane Mode.
So far the only time I have gotten great standby time was when I rebooted my TF and did not open any applications. (WIFI was on FYI)
Brandon
so, the last two night i've gotten great result from stand by mode. The first night i went and killed couple of programs, before putting in AP mode for the night. 12:45 am till 9:00 am from 78% 75%. Last night at 12:00am had 34% this morning at 8:00 it dropdown to 32%.
I took a screenshot of the battery usage after waking up in the morning. Wifi was left on with the sleep policy set to sleep on screen off. It seems to turn back on intermittently but the awake bar seems to happen more often the longer it is in sleep. Is that meant to happen? What does awake signify? That the screen is on?
background data probably running in the background
like weather updates to it to refresh every 4 hours or something
its weird though, towards the right theres like 2 times where the device is awake for long periods of time :S

Would you try "Task killer" for decreasing battery loss?
My battery seems to be dying alot quicker now I have the dock. Hopefully a new firmware will come out that'll lower the battery consumption of the dock when its in standby.
I know this has been discussed in the Gummycharge thread, but its buried pretty deep.
I know kej said that it has to do with the gallery, but I have uninstalled the Gallery3D.apk using the toolbox and I still seem to be losing about 10% per hour with the phone sitting idle on my desk.
Is there something we can use to quantify the appropriate battery drain rate? We all use our phones differently, so we need a way to standardize the battery drain so we can discuss it.
I saw someone mentioned that they were only losing 2% per hour while idle.
Currently, If i unplug the phone, and leave it sit for an hour (after a full charge) with only wifi on (gps, and bluetooth off) I lose about 10% per hour. If i use the phone at all, for example, When i wake up in the morning after a full charge and read the latest XDA posts, or some news articles, I can go from 100% to 85% in about 20 min.
this doesnt seem right.
Can we consolidate the battery drain issue to this post and post fixes and discuss reasons here?
This should have been posted in General first off.
Also, do you have SpareParts installed? If so, use that to check if your phone is entering sleep mode. You may have an app that is preventing your phone from sleeping, which will cause excessive battery drain like you are experiencing. My battery drain is <<1%/hr in airplane mode (I lose 1-2% over 8-9hrs in airplane mode) and when not in airplane mode, I'd say I loose at most 2-3%/hr if the phone is only sitting idle and I'm not using it.

I get a drain of about 3-4% an hour if mine sits. However I leave it on LTE and at the office there is no LTE service yet. Yeah I'm just lazy......lol.
Curious on your SpareParts thing tho. I've never used it much really. Where does it show/display whether or not it is going into sleep mode. now I'm kinda curiosu if mine is correctly or not. Not that I'm very concerned about 4% and hr as I make it threw a full day fine. TIA

If it's not running, it's sleeping. You're battery drain is likely caused by wifi being one 100%. If you are leaving the cell radio on, LTE, and also wifi, that is 3 radios on all at once, draining power.

is that just an issue with the charge? with my Incredible, leaving wifi on saved battery as it did not need to talk to the cell tower and try to get a 3g signal. Also, Before I flashed, I was able to sit all day in school and still be at %80ish power.
I will see what turning wifi off does.. but to be perfectly honest. that seems a little inefficient, that would mean every time i turn on the phone to use it, i would have to turn on wifi and sync, then turn it back off again.
For example, since I wrote this post, my battery has gone from 87% to 70%. 17% in 66 min even with wifi on, that cant be "normal drain". And All i have done is looked at 2 text messages.
Please do not get me wrong, I am not complaining at all. but I would like to get to the bottom of this.
I was on my way to the store to return the charge I hated it so much, but after flashing gummy and your kernel, I love the thing more than any phone ive ever had. So please do not mis-judge my intentions here. I simply want to know if this is normal. In my experience with sell phones (Droid Incredible for over a year, Wife has htc thunderbolt, and now the charge both stock and now custom rom) It is draining much much faster than any phone I have used before.
If this is normal, then I will just deal with it.
I am going to put it in airplane mode for the next hour and see what happens
It is def something in connectivity. Still at 75% after 1 hour in airplane mode. going go turn on 3g only and check again in 30 min.
I was going through battery stats and saw that wifi ON was at 100% and Wifi running was also at 100%..
seems like maybe somethign is using my data. so if that is true, it should try while on 3g and I should get huge battery drain.
will report back
Dude you are NOT alone. my phone drains like a siv, when its nt even being used. I always have LTE off, unless i tether wifi and I always plug it in when i tether so i dont drain. Itll just sit and be idle with NO use and lose 30%. i have gps, wifi and bluetooth off..... wth? this phone is looking ro get returned if i cant sort it out. i cant sit on a charger all the time.
If you are running Gummy, the gallery thing should not be an issue anymore (he fixed it a few versions ago).
When you go into spare parts, go to battery history and change to sensor usage. That will tell you immediately if you have some app that is draining your battery (ie the Gallery).
For the most part the battery killer for people is network searching. 3G,4G and WiFi are all in the same boat in that they will kill your battery if your phone has to constantly scan for them. To my knowledge using WiFi is better on power than 3/4G, but that is only if you are connected to a good signal and your phone doesn't have to search.
Also, I have noticed that the WiFi antenna on my charge isn't all that good, so you may want to keep an eye on it during your day. You may find that it is losing WiFi and scanning without you realizing.
The LTE radio in the Charge can be a huge hog. Especially if your in an area that likes to switch between 4G and 3G. Both my work and my home switch between 3G and 4G a lot and its not uncommon to see my phone drain almost 10% in an hour. On a good day it will be 5% an hour with LTE enabled. With mobile data and wifi off it can go down 0-2% per hour.
As far as I know, this is most likely just a sign of the Charge's battery. I'm not sure what Engadget was smoking in their review, but my Charge gets pretty horrendous battery life, especially in areas with dodgy signal (think constant switching between 3G and 4G). This is the first phone I've bought extra cables for charging in the car and office, but honestly, with these things getting as crazy as they are, I think this might be the norm in the future, what with battery technology lagging behind so much.
Some tips I've learned: turn the Wi-Fi radio off when not in use, and if you're in a really low-coverage area, consider even turning data off (you'll still be able to receive calls).
I live in NY, which is absolutely blanketed by 4g. I get better 4g reception than 3g in some places. I am getting horrific battery life. I just wiped, then mounted each partition individually and wiped and then reinstalled gummy 1.8.5 and per imnuts' recommendation, not install the reboot options. I had a custom rom on this phone within an hour of purchasing this phone, so I can't compare stock to a custom rom's battery life. I just know over the few days I've had this phone, my battery has been terrible. I shudder to think what the Thunderbolt must be like.
Your battery may be draining fast the first boot. Just reboot it. If that doesn't work then it didnt flash properly. Just reflash everything and remember to clear data, cache... hope it helps.
You can download an overclocking app and reduce battery use IF you already solved the battery drain problem.

After using my transformer for a couple of months, the battery life amazed me the most. With about 9-10 hours battery and a couple of days sleep time which was very convenient. Also charging time was very fast.
But after updating to 3.2, I've noticed that when I leave the transformer on sleep like I usually do after using it, it would drain to 0% by the end of the day when usually it would only drain like 1-5% before updating it. I checked the processes and it doesn't look like anything out of the ordinary, and I haven't installed any new applications since the 3.2 update.
Anyone else having this kind of problem?
I have the same problem

I came online to search for the exact same problem if anyone else had. And seems I am not the only one.
Now do you have the keyboard dock as well or just the tablet itself?
My case is that when I have both (tablet and keyboard) fully charged at 100% it will drain out in 18-24 hours whether I use it or not.

Going to give this a try, as Im having this issue as well.
I found that putting the device into airplane mode stopped the battery drain, even though I had bluetooth disabled already, and WiFi policy was set to off when screen is off. Will see how it goes with "Use Wireless Networks" disabled in location settings.
Alternatively, I may write a small app that puts the device into airplane mode when the screen has been off for more than a couple minutes (and disables airplane mode when the screen is turned on)
I have this issue too.
I had mine docked into the keyboard. left it closed and went to work.
When I came back home late, I saw the tablet with 90+% battery and the dock at almost 0%.
Might be the same issue as you guys.
What I did is set the wifi policy to off when screen off.
and I tried again to leave it in the same situation.
Charged it full at night. left it overnight, woke up went to work, and came back. and I checked. Both are still way above 90%.
It makes a big difference for me. =)
I got the battery at 66% this morning and now after no use it was at 18%! I was about to throw my tf out of the window!

I have done all this yet the drain continues. When I compare the battery drain of my tf101 with my HP touchpad, there is simply no comparison. There is virtually no drain even if I leave my touchpad uncharged for more than a day. On the other hand, my tf discharges battery when closed with the dock as if I am using it.
What gives?
Factory reset helped mine. 14 hours 81% with 3 hours of straight use.

I got a huge battery drain today again, got my battery from 57 to 3 on the dock and from 100 to 88 on the tablet with less then 10 hours, just for comprasion I got only 7% down on the dock over night (like 9-10 hours) just this morning. when i checked battry use today I saw 63% used by wifi, this wasn't like this in the morning and all I did is just checked my email and sent it back to sleep, that's annoying as hell, i barely use it and it keeps on dying really fast..
Same here indeed the wifi policy set to never sleep-->Big drain wifi policy set to when screen off-->drain very little

same here,went from extreme drain to normal
It doesn't seem like the power button on the tablet works as well as the one on the dock. If docked, I only lose about %1 per hour.
I've noticed that if I use the one on the tablet, the screen will go dark, but sometimes the tablet doesn't sleep (verified via the battery status). I have the screen set to never timeout and the Wifi set to turn off. Bluetooth set to off.
The tablet lock button seems to be the most reliable and I always get about %1/hour drain when I use that button. Might be just a coincidence.
Is there are "real" sleep mode that we can access? It seems like sleep mode doesn't really sleep, it just shuts down certain items (the screen, bluetooth/wifi). I'm talking about like an S3 state where power is cut to the processor and the only the memory is keep.
If there is a real sleep, it seems like the device has a choice. I want a "Go to the Fok to Sleep" button!

I did this and it worked for about an hour (cpu spy) but then something woke the tablet and it never went back to deep sleep and wiped out the dock battery in about 4 hours. If I turn wifi off standby life is good. However I woud really like to keep the wifi on and get good battery life.
This working consistently for you?
I was ready to replace my dock. This worked like a charm. I went from 1-5% per hour in sleep to <.5% per hour.
I just figured it out this week. I was running WEP at home and this prevents both of my android devices from sleeping like they should. I know I shouldn't be running WEP but neighbor is wide open so I was too lazy to change. Open and WPA allowed sleep on both devices about 80% of the time in standby and big improvement in battery life. Still keeping my eye on it but difference was immediately noticeable with cpu spy.
Sent from my SAMSUNG-SGH-I997 using XDA App
After further review it appears it wasn't WEP. All was well until I put my laptop and computer back on wifi then both infuse and transformer had inconsistent sleep. I disconnected computers and both android devices sleep again. Updated my router firmware but no improvement. Any ideas?
Update: I believe my router is doing this. Works fine until I connect other wireless devices then drains. There are sporadic reports of this in other forums for dlink dir-655.

After 3.2.1 or possibly the Maps update, my wifi stopped powering on after sleep. It would start and stop, even airplane mode would not break the cycle. Frustrated, I turned the location setting back on, reinstalled maps and left it undocked. Woke up this morning. 98% battery. Arg. WTF is going on? This is maddening. The dock drain seems to fluctuate between 8-40% in 8 hours and I get 2% undocked? Is the dock the issue (that would suck).
I'm docking it again tonight. Maybe it was reinstalling maps? This is really frustrating. With 3.2.1 the browser is stable, Skype video now is going. This is the last issue with TF before I can strongly recommend it to my friends.
I am getting some nasty battery drain now too. Approx 30% overnight with wifi off. Im very happy that skype works though.

Hi XDA,
I'm having some problem with my Huawei Mate P7,
Recently when the phone is in standby, it can drain the whole battery from 100% in a night of standby(while sleeping).
I've reset to factory hoping that would fix this, same problem. I updated to latest Lolipop thinking that would help, same problem...
When the phone is in Smart Power mode and I'm using it while on, the battery hardly drains. It's only in standby it seems to happen. Even not installing any apps except FB it dies.
It seems to be in the stats, 80% power usage is wifi/3g modules.
Any idea what could be going on here? Am I forgetting a setting? Is the battery a problem?
Thanks
Are WiFi settings are those?

Yip settings the same as the screenshot Except mine is "Keep Wi-Fi on during sleep - Only when plugged in"
So I charged it to 100% yesterday and left it switched off, plugged it back in and it had lost 40%, sitting at 60% remaining...with it switched off from 100% battery.
Starting to think the battery is dying Attached pics of usage..brand new software, reset, no apps installed, running on Smart Optimization
same battery drain. Updated to 6.0 and the problem is gone.
4.4 was fine. But all 5.1 had the same battery drain issue

Go to Google settings and turn off location reporting.

Thanks for all the assistance all, I think the battery is just going bad, it takes forever to charge, leave it charging all night sometimes and its still not full tried multiple chargers too
Can't get more than 6 hours out of it it seems tried all suggestions including upgrading to 6.0(made a difference with speed much quicker now though)
Anyone got any other suggestions??
How good is your mobile signal?
If it's trying to use 4G and searching for better signal it could chew the battery. It's much easier on battery running on 3G.
