E330 - Battery drains, need details on what devices & services to disable

Hello guys!
It is a well known problem that in some cases the battery drains while the device is shut down. I have read the forums and know that I will have to disable certain devices. Unfortunately I have no idea how to do it / how to find them on my laptop.
I have a freshly installed Windows 8.1 on my PC, no bloatware on it (yet). So everything I do I do myself, through device manager etc. But where to start? I know my laptop automatically starts up when I "open" it. This does not happen, if I remove the battery and put it back in. So there must be a small current flowing? Maybe THAT is my culprit?
Please help me out here guys.
Thanks a lot in advance! Have a nice day!
Solved!
Go to Solution.

Quick tests show that in BIOS disable "Wake On Lan on battery", either keep it on AC only or disable completely. Helped me a lot. But there is still some small drain. Oh well. Nothing is perfect.

Hi,
as far as i know, there�s only one possibility to create a .m3g-file and that�s not a cheap one. You have to buy,
steal, copy or whatever a plug-in called "Swerve Studio" for 3dsMAX. Build your content with 3dsMAX and
export it than as .m3g.
Hope that helps a bit

Welcome to the Apple Support Communities
I can see that the full charge capacity is too small for a Mac battery or, at least, for a recent Mac. However, I think that OS X is displaying that you have check the battery because its capacity has decreased a lot.
In this case, you can continue using the MacBook Pro until the battery stops working at all or because it doesn't meet your requirements of using the battery. If you can't afford a new battery, wait until you can change your battery

IPhone Battery Drain, 7.1.2, I Have A FIX!

Hello everyone! My name is Gabriel Chen and my iPhone has been having trouble with battery draining, and overheating. I'm here to tell you how to fix it. This is completely different from the rest of the posts because I've discovered something interesting and new.
Background (I'm a little long-winded, sorry. Just skip down to "What-to-Do" if you are pretty sure you've had the same problems as me):
I got my iPhone 5s when it first came out. It's battery life was amazing, then the fire nation attacked. Jokes aside, the battery became worthless about a month ago after I updated to 7.1.2. I thought the issue was 7.1.2, but now that I fixed it, I don't think it is. I took my phone into the apple store about a week ago because I was off to college and needed to fix this problem before I left. They ran diagnostics and found kbd and backboard errors. They immediately replaced it. I was happy because I had a brand new phone, but the battery issues came back, and this time even worse. My phone was burning up, even hotter and it even froze sometimes. I then took it to a store near my college–which was difficult because I have no car here–where they did a reset because that's what they always do. I sat there and played with the phone to make sure the problem wasn't there. Turns out it was still there. I love apple genius bar employees, but not all of them are very knowledgeable about the products and how they work. I don't blame them because: updates can always cause new problems, it's probably above their pay-grade to memorize what every single error code means, and they don't necessarily have knowledge that lets them troubleshoot any problems that involve hidden processes that their apple-issued easy-button diagnostic test doesn't tell them about.
I then approached another employee who helped me immensely. He knew something was wrong, which was awesome because most employees do tend to blow you off, so he decided he'd try to help me fix it. He had a lot more knowledge about the phone. This time he found kbd errors again so he replaced it. After that process, he disappeared into the back of the employee's only part of the store. I tried playing around with the phone, and it was clear that the problem persisted. I then went and got help again. This time, the new person who was helping me went to the back, and I waited around for about an hour and a half not knowing what was going on. The whole time, I was wondering where the first guy who helped me disappeared to. For the sake of convenience, the first person who helped me in this paragraph will be Ian, and the second will be Will. Will eventually came back out, this time bringing Ian along with him. Turns out Ian had been doing research for me in the back for the last 1.5 hours and found that the problem probably had to do with iCloud. My phone was draining and overheating due to its attempt to download some sort of data with no success. So each time it failed, it would retry over and over again. This explains the overheating and battery drainage. We deleted some stuff from iCloud and it got a lot better.
The next day though, the problem came back. I was so frustrated so I've been trouble shooting for the past 5 hours. Eventually, after 4 hours, I tried using different iTunes accounts. There was no battery drain when I used these. When I used my original account, there were still problems. So I tried turning off iCloud on my account. Still, I had no luck with it. I eventually tried something else which finally fixed it! My phone now no longer has problems with battery drain and overheating.
What-to-Do
1. Go to Settings —> iCloud —> Delete Account
Don’t worry, as long as you click “keep the stuff” or whatever it says, you won’t lose stuff
2. See if your batter still drains by leaving it on and watching the battery. Touch it and see if it’s heating up. If your battery is draining 1% every 2 minutes, it definitely is still having problems. It’s your own choice, but even if it does drain, I would follow the next step anyways. If it doesn’t drain, the issue definitely had to do with iCloud. Now, log in once again.
3. Make sure all of the iCloud data that you care about is stored some where other than iCloud. For example, make sure your Pages files are on your computer.
4. Go to Settings —> iCloud —> Storage & Backup —> Manage Storage. Then delete the stuff under Documents and Data. I REPEAT, DO NOT DELETE WITHOUT FIRST MAKING SURE THE DATA IS ON YOUR COMPUTER IN SOME SHAPE OR FORM
Why? What is probably happening is that there is probably data that is trying to get onto your phone. This data is failing to do so which is causing an infinite loop of effort and failure which drains your battery and makes your phone work really hard. Apple should code a fail-safe into this to stop the loop, but they haven’t yet.
5. You’re done with this part! For some of you, like me, your phone will stop draining. If so, you’re done! For some of you, it will start draining again! Here’s the part that took me 5 hours to figure out, mostly because I was just frustrated and venting.
6. If you’re still draining, go to Settings —> iTunes and App Store, and turn off SHOW ALL Music and Videos. What this feature does is it will display the purchased items that have not been downloaded, but are on your iTunes account, specifically Music and Videos, within the the corresponding apps. I understand that you probably like this feature and that you’re probably unhappy that I’m telling you to turn it off. This is a glitch or bug that Apple will probably come to fix if it comes to their attention eventually, so don’t worry. When they do fix it, you can turn these back on.
Why? For some reason, the battery drain was being caused either: by the phone failing to fetch data from your iTunes account, pertaining to purchased items such as songs and videos; or by the phone repeatedly fetching the data, instead of just holding it in place.
So, this fixed my phone completely. Please rate me up if that’s even possible. If you’re an Apple dude, I’d love to receive rewards if this was actually useful to you guys (haha, sorry I’m just a little proud of my accomplishment.) If it doesn’t work, try to trouble shoot and figure it out. If you would like clarification, feel free to comment or whatever it’s called. If this doesn't fix it, maybe try getting it replaced in an apple store because that might be the issue.

Thought it had worked but soon found out it had not.
after further days of trying finally, solved it for me Yesterday.
turned off notifications when locked, and bingo, wow.
i have not turned off iCloud but location services are also off.
best thing to do I found was keep checking your usage, settings, general, usage, and flip down to bottom, if the standby and usage are similar there is a problem, if there is a big difference then all is ok. Just keep turning things off and on until the difference is very apparent.
something on my phone was keeping the phone alive even when turned off, and I think this was the phone repeatedly trying to update continually.
to me this is definitely down to the iOS, my wife has exactly same phone and iOS but hers doesn't have any problem and the battery lasts for days.
the guy at the Genius Bar told me to restore the phone via iTunes, not iCloud. This is because iCloud remembers the exact info from your phone and simply reinstates it when you restore, and this includes the iOS too.
when I get home from holidays that's what I'll do, or wait for iOS 8 in few weeks. But I'm so pleased I finally made it work, I was beginning to think ditch the phone and buy Samsung.
anyway anyone out there please try my final solution and let me know if it works for you?

Battery drain from Bedside mode

Hi, I've encoutnered battery drain before with programs and OS updates. I've done resets, reboots as well as battery reinserts. My device seems to be stable after 10.3.1. I had WiFi, Network and blend, and power saver on at 5% battery. I wasn't using the phone but just used the Blackberry blend software on other ohter devices to check emails. The battery lasted about 4-5 hours before it finally powered off. When i put the phone with the same options but in Beside Mode and did a lock to clear the active use of the display. Apart from Blackberry Blend being off and showing as such in Quicks ettings. The battery drain went down 97% to 74%. By the device manage the battery went down over 2% every hour in a standby mode, where compared to out of Bedside mode with blend on it was 1% an hour. No programs really stand out as causing drain nothing 10% or more since last charge before I put it into Bedside mode. Even normal standby mode with the screen off the battery drain is less. What could be causing this, anyone heard of sometthing similar.

the battery drain in the Night Mode is also happening to my leap device, with all the apps closed, and even Economic Mode activated. i try to figure out what is happening. I will come back if i find the solution. I am also looking for a Battery Saver app. I had a great app on my previous phone, an Android, but I still look for a similar app for BB10.

Satellite Click Mini L9W-B battery drain

hi all
Ever since the 1.70 BIOS update I've noticed some battery drain.
I left the device with the lid closed for 12 hours and battery charge dropped from 20% to just 3%.
i also noticed the two batteries give max 5 to 6 hrs compared with what used to be 10 to 12.
has anyone else noticed this?
thanks

thanks for this.
i'm not trying to switch it off completely, just saying it used to last much longer when no apps running and the lid closed with the old BIOS.
also yesterday plugged the tablet part in to charge, after 30 mins had to unplug it however the status remained "plugged, charging" so when the battery charge dropped to 0% the device did not switch off and continued running for more than one hour!

Battery drains very quickly while using 3g

My phones battery drains very quickly while using 3g service, need some suggestions or solutions to rectify it.
Location: Bahrain

Thanks in advance

You could also check what it draining battery under settings > power management > battery usage. Check this when you have less then 30% battery left and you should have 3G enabled from 100% battery.

Battery drains while asleep

Hello,
I have a MBP 2.2Ghz, fairly new, running OS 10.5.2. I've noticed recently that when closing the lid, putting the computer to sleep, the battery drains fairly quickly, not what I'm used to with a sleeping laptop. If I close the lid for 2 hours, I lose 10% of my battery. If I let it sleep all night, it's pretty much dead in the morning. That doesn't seem right.
I know the MPB is asleep, the light is pulsing. But could there be something running in the background that is draining the battery? How would I debug this?
Thanks a lot! This forum is most informative.
-troy

There are three possibilities here: 1) the computer isn't really asleep, 2) you have a USB device connected to the computer that is drawing power, 3) there's something wrong with the computer and/or battery.
You mention the flashing sleep indicator so that suggests the computer is going to sleep. But is it staying asleep? You might want to open the Console and see what is happening between the time you put the computer asleep and the time you woke it up. If you put the computer to sleep at 10PM and woke it at 7AM there will be a few entries around those two times involving the computer sleeping and waking but nothing in between. If there is, you know there's something going on.

Since I downloaded iOS 6 I have noticed increased battery drain.

I have an iPhone 4. Since I have downloaded iOS6 I have noticed significant increase in battery drain. Anyone know what is different in iOS6 that would cause it. If so, any ideas what I can do, if anything, to reduce the drain.

Cmaguire50 wrote:
Since I downloaded ios 6 I now have to have wifi to get into iTunes and my purchased items
And that is the way it has always worked - unless you were accessing iTunes on your computer with an Ethernet connection to the Internet. Otherwise, on an iDevice, you must have access to WiFi or be using a cellular 3G/4G iPad in order to access anything in iTunes.

Temporary Fix for battery drain for iOS 5

After going through various recommendations, the following worked for me:
1. Notifcations - Settings -> Notifications
     Under the 'In Notifcation Center' category, select Calendar and turn the Notification Center option 'OFF"
     This seems to be the main problem for those that have their exchange accounts synced with their phones.
     In addition, I also removed all other items from Notification Center except for Weather and it seemed to slow down the battery drain considerably.
2. Location Services - Settings -> Location Services
     You can see what apps/services have been using or currently using the location service by noticing a grey or purple arrow next to the line item. Go through what items have the location service ON, and see if you really require some of them to access your location information, the less the better.
This helped a LOT: Scroll down to the bottom and access 'System Services'. Under 'System Services' uncheck all except 'Cell Network Search', .Compass Calibration' & 'Traffic'.
3. Let the battery drain completely until the phone switches off on its own, then charge it to 100% without using the phone. Not sure if this really helped, but I wanted to try as many options as possible.
I think the drain is due to a combination of different issues, and hope Apple release a patch soon to fix this annoying problem, till then I hope the above helps.

The 3G option. WHEN that option is off, iphone is connected to your operators 2g network! Because 3G has often weaker signals then 2G
Good luck!
