[Q] Losing 30-40% battery overnight

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.

[Q] When not using the pad?

So I was wondering, if I'm not going to use the table for a whole day (or a little bit more) is it better to shut it down completely or just leave it on stand by? and, is it safe to treat the tablet as a cell phone, I mean charging it everyday before I go to sleep?
Thanks!
ps: I tried searching but I couldn't come up with anything helpful, I would appreciate a link tho....

I rarely ever turn off my TF. I always keep it on and let it go to sleep. I feel like you train the battery more effectively by letting it slowly drain vs just shutting it down completely.

I turn it off when I know I won't be using it for a long time.

only when i want it to have a reboot,i shut it down(never rooted)

I just let mine sleep.

which one is better for the battery?

Mine has 10% left usually at bedtime, I plug it in to charge and shut it down while I sleep.
(So its charging while powered off and not draining any while charging)
When I wake up in the morning I turn it on.
Repeat ...

10% at bedtime everyday wow I thought these got like 9 hours screen on time
Sent from my captivate BLAZING on firefly 3.0

I throw it in AP mode whenever I'm not using it and it will only drop 5-8 percent every 24 or so hours..

I rarely switch off my Transformer. When necessary I will charge it, but unless I need to reboot for a different reason I let it sleep. Actually, I don't think I have left it to go to sleep by itself, I always turn off the screen when I put it down.

Battery question. Dieing when powered off

Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?

defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?

Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%

Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.

Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.

[Q] New battery from T-Mo, how should I calibrate?

Just got a new battery from T-Mo today, as my battery life has been depressing since 2.3.4 update a month ago. With the old battery, I tried 5 cycles in a row of fully discharging, and fully charging while off. No difference, Juice Defender, m a y b e a little difference...been searching around for an hour, and remember a few things from reading XDA over the past month. So many different techniques, most for rooted phones, mine is completely stock(and I do plan on rooting soon still researching/learning), 1st thing I did when I took it out of the mail, was put it in the phone, and charge it while phone is off. Green LED has been on for 3 hours now. I'm scared to turn it on!! How do I calibrate this baby and make sure to the best of my ability this battery stays good?? Sorry for essay on one question.

wow, 56 views...0 replies. Nice.
I read one of the MANY threads yesterday on this, a guy said to someone, something along the lines of..."use the search, there are countless threads on this...and you can find this, like I did"...
This is what he said.
Charge the batt all the way while off(wall), then unplug, plug back in, light will be amber, then change to green. Repeat this process till The amber light doesn't come on anymore.
SO, I did this...about 100 times. It would go amber, blink, amber, then to green with no blink. Then sometimes it would go amber, and blink to green. back and forth. Seriously about 100 times. It never would initially light green. Amber everytime.
So I finally gave up, went to sleep. Still getting mediocre battery life today.
Where is help when you need it??

Drain it until it turns off, plug in, turn phone back on and let it charge to 100%, unplug, drain until it dies, repeat process 3 or 4 times. Download calibration app from market and use it when 100 % is reached.

1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour

That was the official reply from HTC during the EVO 4G days

So instead of fully charging while off, fully charge it while it's on? And, the calibration app, is this a general statement, like any app, or a specific one?

It's called Battery Calibrator. This is the process I found on the forums, it works, on stock battery I average 5 hrs screen time and can get over a day on one charge. On the Anker I get even better, I have been methodical about conditioning batteries and I am getting great battery life.

Yo, when u see that green red led combo, know that your phone is telling u that battery is overheating/overcharging. It's colorful for a reason, telling u to stop.

It is not red, it's amber(orange/yellow) And it was on this thread that I read to use that technique - http://forum.xda-developers.com/showthread.php?t=1139092
He says "use search, it can only help you"
well, like I originally said, I have seen numerous techniques on calibrating. Just trying to find a solid one. That guy @KillaHurtz had a lot of thanks and seemed to know what he was talking about, but like I said, I tried his technique 100 times and couldn't get the results he was saying "repeat until no amber light showing", and that was after leaving the phone on charge(while off) 3 hours after it already turned green.
So one says, do this...another says...that is overheating/charging your phone....
are you mistaking my amber for red? I seriously hope I was not damaging a brand new battery before even turning my phone on with it.

Apple recommends this: http://support.apple.com/kb/HT1490
1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again.

Rhiannon224 is right. I don't repeat the process 3 or 4 times like she does, but once a month I let my phone run down until it turns itself off. Then I leave it off and charge it overnight. I get better than average battery life, although I don't get 5 hours of screen-on time with the standard battery or with the EVO3D battery (1730 mAh). I easily make it through my normal usage for a day -- 20 to 30 emails (gmail and HTC Mail app set to push), facebook and weather sync every hour; Plume sync every 30 mins, 20 or so texts, 15 to 20 mins of phone calls, some Slacker radio, short sessions of Cordy or Angry Birds to waste a little time.

Hah, sorry for the late response. When I said red, I was referring to amber. There are only 2 LED colors for the Sensation. Have you tried disconnecting the charger, turning off the phone, then connecting again? If it wasn't at full cap, it'll go back to being amber. Do this too many times, you'll notice it'll start flashing green and amber, signalling that the battery is getting overcharged.

If your phone is on and charging and you get say a text/email or other notification, you will get the green/amber flashing as well. I'm not sure if the battery is overheating of it will flash multiple colors or not however owning a sensation I can tell you from experience that my phone has been hot to the point where it is uncomfortable to hold charging or not and the only time I have seen an orange/green flashing combo is when it was charging and I had a notification. Orange by itself means charging. Green by itself means fully charged. Hope that helps with the confusion. For the battery life, if your phone is rooted, I recommend using faux clock to manage your CPU levels and keep your battery life up. If not, try lowering the brightness of your screen in order to make the battery life last longer. My phone gets me through a full day without charging (pre and post rooting) and I'm on it quite frequently and all I do is use my phone as usual and drain it until it dies once or twice a month to help prevent the "memory effect". Hope this helps!

[Q] Odd battery life situation

I've always been reasonably happy with my battery life. If I use it heavily it goes down. If I don't it can stay charged for a couple of days. Within the last week or so that has dramatically changed. All of a sudden it barely makes it through the night from a full charge to 10% or so. It also "seems" that normal use drains it at least twice as fast. Anecdotal but I know something is wrong or different.
I haven't made any changes to my phone for months. I'm running existz kernal for 2.2 and that is the only customization. I did get a bunch of app updates but that always happens. The battery use screen shows the batter is being used for display but over night, it doesn't/shouldn't display much.
Thoughts on how to find what the heck is going on would be appreciated.

Use spare parts app and find out battery stats on partial wake clock usage and sensors usage

What I would do if I were you is charge to 100%, recalibrate, and take the battery out for about 15 minutes before you put it back in and turn your phone on. I dunno.why this procedure worked for me but that's just a suggestion if you don't wanna flash to stock and back to whatever you're using.

Uninstall updates, then add them back, one at a time.

I notice dramatically different battery life when I use this procedure to charge my phone known as a bump charge.
1) charge to 100% or as close as your phone will get while it is on.
2) Disconnect charger
3)Turn off phone
4)Re-Connect charger while phone is off
5) Wait until the phone says 100% charged while it is off. You can check the charge by using the volume buttons if the screen is asleep.
6) Unplug charger. (This is important. If you boot your phone with your charger plugged in it can give you inaccurate battery information.)
7) Boot up the phone.

That is really odd but mine has started doing the exact same thing. I have never had battery issues and for the first time today my phone was completely dead within 6 hours, and the past week it seems to hardly make it 12 hours.
I was just assuming it was the launcher I was using but I removed it and it never helped whatsoever.

I'll give that a try... it made it through last night in pretty good shape though. Confused I am.

Not sure if this helps or not, but here is my experience.
I have two wireless routers in my house. One I keep locked to N-only and the other to G-Only. The N router I have suspected for some time has a weak or flaky radio because I can watch the signal strength fluctuate wildly over a period of 10 seconds or so. I noticed a while back that when my phone is connected to the N router it will kill itself pretty much overnight. When I disable that connection and let it connect to the G router it only loses a couple % over an 8 hour period.
I don't know if it is due to being connected to N, or if my suspected flaky router is causing it to use more power staying locked onto the signal or something of that sort.
