Hello, @eddieleon7pc
It seems that after upgrading to Windows 8.1, that your not getting the same battery life. I'll try to assist you with this.
Here are a few documents that may help:

Battery Drain Issues in Windows 10

Not a complaint but an observation...all of my Windows 10 Tablets have significant battery drain.
2 Surface Pro 3's
Dell Venue 8 Pro
HP Stream 7
(my Lumia ICON with Windows 10 also suffers, even with a lot of background settings off.)
On my smaller tablets, I forced hibernation to help for now. I used to get 3-5 days sleep/standby on my Venue 8 Pro.
Wanted to make an official thread (since I didn't see one)...I heard there was an "Intel Bug" that was causing some drain.

Envy 6 1103 updated to windows 8.1. Battery drain, driver issues...factory restore?

Hi folks,
I own a envy 6 ultrabook 1103el and i'm just another disappointed user who updated windows 8 to windoesn't 8.1...
i got all that problems that everybody is posting in the forum, so:
-several driver issues: mainly the most relevant seems to be the managing of graphics:..switchable, AMD 7670m .
i manually installed the beta drivers from the amd support (HP support center has not updated the drivers on the dedicated page of my computer) and now it seems working. but i noticed that there is a consistent battery drain... dropped from 5/6 hours to 3.5 hours.
lookin up some posts on the forum, i saw that's a pretty common problem, but i need thi pc for work and the battery life is fundamental for me.
so my question...as far as i know there should be a ssd/partition on my pc with some recovery stuff on it. is it possible to rollback to windows 8 with a factory restore? is there ANY way to have windows 8 back? the computer is quite new, so i didn't even had time to create a windows recovery disk or something like that...

If you are able to boot into Windows 8.1 it should be quite straight forward. The only determining factor is whether r not you did an upgrade or a clean install. A clean install would have deleted the recovery partition and an upgrade would not have done that.
Use the search charm and type in Recovery manager. Click on the HP recovery Manager icon that appears below. That should start the HP recovery Manager. Click on System Recovery button that is in the I need help now section. In the new screen select factory Image recovery. That will start the process of installing the operating system that you PC was delivered with.
An Alternative would have been to use the DVD or usb recovery media that you shoud have created shortly after you initially setup your notebook. You said you didn't have time. Well, you did make a choice not to make the time for that important detail. You can still make recovery media if you have not made a set yet. I recommend that you create the usb recovery media. It is far faster and considerably more durable than DVDs.

Battery Drains Very Fast After Installing Windows on BootCamp.

Hello,
I Bought MBP 13" Mid 2014 Retina Display last week and it wasn't a good start for me with Apple as I face the problem with FileVault and now with the battery. I had installed windows in my MBP through Bootcamp, but after installing it my battery drains vey quickly. It doesn't even last for more than two hours. Does anybody has any idea what should I do to fix this problem?

How long does the battery last on the OSX side under similar use?

Dell Venue 8 Pro Battery Drain, Support No Help

I lose a silly amount of battery life when the tablet is not in use.
Battery life isn't great when in use either.
Dell support wouldn't do an exchange because the diagnostic check came back fine.
They did tell me to turn down screen brightness etc., not very helpful because I've tried all that. Stayed on Dell's recommended settings trying to avoid this issue. My sleep study seems to indicate that the unit is rarely in sleep at all.
If a fresh install of windows doesn't fix this. I'm done. And dell support has been anything but actually supportive. If it doesn't fall in a checklist you are sol.

THIS IS IN RESPONSE TO THE PERSON THAT SAID THEY DO NOT WANT TO RMA IT//WARRANTY WHEN STILL NEW AND ALSO RELATIVE TO POSTS ABOUT CHARGING WITH BACKUP
I know my response is rather dated, but when you have a severe battery drain issue, just return the unit for an exchange where you bought it.
I know some people mite not have bought it at a "brick" joint, but you should always try to buy your etoolz online, but at a local store for pickup, so you can check it all out and within that window of time offered, return for refund or exchange.
BBuy locally tried to send stuff back for warranty reply, but I always point out the fact it's still under returnable terms, so I can either get a refund or return/exchange and not mess around waiting on my gear.
There are also other ways to buy an other "new" tablet and "exchange" it//the old one also thereby bypassing all stops and go's and getting your new tablet replaced.
I'm always plugged in or on an external battery pack//backup battery pack on DV8Pro anyways, so battery life for me is always longterm.....
For those of you finding you aren't able to charge your via backup battery pack due to cable issues, remember you need a "dumb" usb//"charge" only cable or dumb dongle that makes your cable ""CHARGE ONLY"",,, then it will always charge via any usb powered source.
For example for you that don't understand fully, sometimes devices such as rechargeable peripherals like keyboards and mice and all kinds of non pc devices that now use what appears to be a data cable but is only a charging cable, which does not allow throughput of data due to the fact it's sole purpose is to CHARGE a device, that cable will work.
Like some small radios and bicycle lights and other devices now come with "USB" enabled recharging, and the cables look just like a data cable and will fit a fone, phablet or any standard mini usb plug, those cables are usually CHARGE ONLY, and this is what you need to add to your DV8Pro so it will charge universally bus wise.

MacBook Air Mid-2013 Battery Draining FAST (about 5-6 hours at best)

I have been having problems with my Mac's battery draining very fast even on light usage. Simply using Safari will drain my battery in 5 to 6 hours, when my laptop would last the stated 12+ hours before when browsing the internet. I followed these steps yesterday...
Reset com.apple.finder.plist, com.apple.sidebarlists.plist and com.apple.desktop.plist
- Open a new finder window
- Choose Go > Go to folder. Your destination is ~/Library/Preferences
- Locate com.apple.finder.plist and rename it to com.apple.finder_backup.plist
- Locate com.apple.sidebarlists.plist and rename it tocom.apple.sidebarlists_backup.plist
- Do the same for com.apple.desktop.plist. Note: This file was missing in my folder. If so: nevermind.
- Open Terminal and type: killall Dock
Reset your SMC:
- shut down your system
- plug in the magsafe
- hold down shift+ctrl+alt+power for a second, then release. Your magsafe should blink
- do this three times
Reset PRAM:
- turn on your mbp and hold down alt+cmd+p+r immediately
- hold down the keys until you hear the startup sound the second time
- release the keys and let the MBP boot.
Give your system some time to adjust to the changes: after a while it should show you a much increased battery time.
...but to no avail, it didn't have any effect on my machine. I'm not sure what to do. :'( Activity monitor shows Safari as having a "10.7 average energy impact" (I don't know what that means in all honesty) and is the highest consumer on the list, with Dropbox being number two on the list saying the average is 1.9 at the moment. I quit background applications so I know that's not an issue — I don't know where to go from here. Also, my battery max/health is 6909 at 97% health, so I do know it's getting a near-full charge. I miss having 12+ hours of battery as that's what I bought this for. Should I go to the Genius Bar and see what they can do?

Random iphone 3g battery drain ... appears to be a background mail check

Phone Info: Model: 16GB/Black, 3g ON, OS 2.0.1, Mail: Push On and Manual Fetch, Location SVCs ON, LCD auto bright, Own this phone for 20 days.
I noticed (twice) that my phone battery drained up overnight after a full charge 5 hours earlier. It happened once with OS 2.0 and other time with OS 2.0.1. I started suspecting background apps (while the phone is in standby - blank screen) probably doing some unnecessary work and draining the battery juice.
I did some investigation during last week to turn on/off various parameters to close on which app is causing trouble. It appears to be Apple mail program! If I turn off all mail accounts, phone "Settings->General->usage meter" goes up by approx. 1min/hour when the phone is in standby. With my 3 mail accounts (2 yahoo and 1 gmail) on, usage meter goes up anywhere from 4-12 mins/hour or lot longer in some cases. This translates to about 100-250 mins of phone usage time/day without really opening up the phone. On 3G phone, 4 hrs of usage is where battery goes from full to 10% charge.
Details: The above problem doesn't happen always! This happens only when mail application spins in the background for a *long time* to fetch or sync mail. When it happens you see a rapid battery drain in standby. This is a most common scenario when you have a network connection (web browsing OK) but somehow the mail sync up (thru' SSL POP) takes forever. This is what I tried to reproduce: Goto mail->open account1->open inbox .. when it is spinning to fetch mail manually.. 30-45sec later give up and try another mail account..repeat above and press home button finally(at this point as a typical user you waited 1-2 mins to get mail on Wifi and gave up.. we are talking about your inbox having zero new in/out mails!. This is just for syncing your phone with the server). You can press standby and turn off the phone screen. Check couple hours later and usage meter goes up by how long the mail was spinning in the background.
I think the right implementation is Apple Mail should turn off background check when the user closes the app! OR at the least detect the phone is in standby and stop spinning after a small timeout.
Mail Push on or off has no effect on the problem. No other settings (3g on/off, GPS...) have any effect.. they don't increase background battery usage!
Appreciate your posts on any workarounds or fixes to this problem.

I'm flying blind here, a little, because I'm not currently using a 3G iPhone. However, I use MobileMe on my iMac, MacBook Pro and a Windows Vista laptop. Keep in mind that MobileMe syncs not only your email, but your calendar, contacts, bookmarks, etc. If possible, turn off MobileMe at night when you don't need to sync. See if that stops the spinning globe. When Apple changed from dotmac to MobileMe--offering "push" email, calendar updates, etc.--battery drain on the iPhone was bound to happen, because it takes battery power to connect to the MobileMe server. That's true of BlackBery's as well as any other mobile device using "push" technology.
Turning your POP and other email accounts off probably doesn't change MobileMe's synching with calendar, contacts, bookmarks, etc. I've noticed when I make a change on my MacBook Pro or iMac that the change does not take place immediately, unlike a BlackBerry connected to an Enterprise server. I'm assuming you're not using ActivSync with an Enterprise server. Neither do I since I use the BlackBerry Internet Service (BES). Emails, using BES, usually hit my BlackBerry before hitting Apple Mail on my Macs, but BEST is only pushing email.
Best answer to problem? Turn off your iPhone at night and save battery power. Not a perfect solution if you want to take phone calls at night. But until AT&T improves its 3G network (more towers, more 3G radios, etc.), that's the easiest way to keep your battery powered.
I explain the battery power situation in my V1 iPhone review. Google "Mobile Telephony Innovations iPhone" and you'll see the review listing.

Battery drain after updating to iOS 5.1.1

After doing the update to iOS 5.1.1 the phone is getting hot "warm" near the processor and the battery drains about 1% per 10 mins in standby and 10X when running an app. Meaning that the phone will run about 6 hours when it used to run for 48 hours on a charge. When putting the phone in airplane mode battery life appears normal. Following others that have reported this issue, I've done a Reset All Settings and two Erase All Content and Settings then restored from back up. Unfortuately what worked for others has not worked for me...
Took the phone to the Apple store and was told by the genius that there are no issues with the update and that location servers were to blame. Explaining over and over and over again that none of those settings have changed and that the only thing that changed was the update I got no answers, just more frustrated.
Currently I have all location services off and wifi off but still have the same problem.
Looking to either find the magical reset sequence that others have has success with or just roll back the update.
Help.

Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

T540p battery drain in S4 state after Bios and Intel Wifi driver update

Hey Guys,
on my T540p, I configured the rapid start technology according to
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days.
I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to
https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Battery-drain-when-powered-down-Y410P/td-p...
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided? Has anybody experienced the same issue?
Best,
Martin

mka1284,
you could check out devices that might resume laptop from the sleep modes and disable them. Type in the following command in the cmd line window:
powercfg -devicequery wake_armed
Also the following command will show you report about power management. Open cmd window with administrative rights and type in:
powercfg -energy.

Nokia Lumia 1520 Overheating & Battery Drain after...

Hello,
I've been experiencing an intermintent problem with my Nokia Lumia 1520 (AT&T, 16GB model) where my phone overheats and the battery drains. The problem started after I upgraded to Windows Phone 8.1 and Lumia Cyan. As of now I haven't figured out a good step by step method to reproduce the problem on demand however I have noted that when this problem occurs and I wake the phone and unlock it the Start screen shows a never ending or unusually long "Loading" message and my phone will overheat and drain the battery. So far the only way to mitigate the problem is by shutting it down manually or performing a "soft" reboot of the phone. Afterwards the problem gets resolved and the phone resumes normal operations after rebooting with the phone returning to a normal temperature and battery drain rate that is consistent with the use it is being given.
Given that I don't know anyone else carrying a Lumia 1520 has anyone seen something similar to the problem I am describing on this post with their Lumia 1520 unit after updating to Windows Phone 8.1?
So far the only big resolution step I've taken is to perform a complete phone reset and not recovering the phone from my back ups, effectively making it a "new" phone in terms of settings and software conditions.
My theory for this problem is that it is software driven as an overheated phone and a stuck "Loading" message instead of the Start screen after unlocking the phone indicates that a software process (either OS or separate Application) may be behind the issue.
Thanks for any assistance on this matter!

Did not work unfortunately... But I have resolved my overheating and battery drain issue...
CORTANA is the culprit and needs to be unpinned from the start screen.
Here is the process if CORTANA is piined already..
1) Unpin CORTANA
2) Go to "Settings.. Applications and open Cortana
3) Turn off Cortana
4) Phone will RESET
5) Go to "Settings.. Applications and open Cortana
6) Turn on CORTANA
DO NOT PIN TO START SCREEN
7) Swipe your start screen over to your applications
8) select CORTANA and allow it to set it self up again.
Now CORTANA is still accessible by the Search icon or from your application menu.
Now your battery.. Before the update my battery was reading "1 day, 14+ hours"
After update After recharge I was getting 14 hours then it would start draining.
After taking CORTANA off the start screen my phone stop getting hot near the camera (Upper left) and after 2 days (Battery cycling) my battery has returned back to reading "1 day, 14+ hours"
My assumption - The matter will be resolved with the Lumia Denim update coming later this qtr.
When that arrives my understanding is CORTANA is off BETA in US. Some additional Firmware tweaking, along with the camera updates and more.. Which "SHOULD" resolve this battery drain & over heating with CORTANA
Per my experience, I believe you're right that Cortana is the culprit for the problem described by the original poster. I unpinned Cortana from my start screen 6 days ago, and so far so good. I have not had a recurrence of that problem. I did not turn Cortana off and then back on again though. I just unpinned it, and that seems to have done the trick.
I'm also hopeful the Windows Phone 8.1.1 and Lumia Denim update will fix this since Cortana will be off Beta in the U.S.

T410s battery drains quickly while suspended.

My T410s battery will drain within 2 days while suspended. I have not tested hibernation but haven't noticed the same amount of drain. On all my other laptops running Windows 7 or any other version I can suspend the computer and will see a slight battery drain over a 2 day period but not a complete drain. I have it configured w. a SSD and wonder if this is the cause. Are others experiencing the same thing?

I have no issue with hibernation. I have it with suspend. I did the update and the issue remains. As described above, 7% over 10 hours is 30% over a weekend which is what I experience. For me while suspended that is unacceptable. I have an apple and had a Dell and have owned Lenovos over many generations. Including the Lenovo that colleagues currently have. None of these laptops have this issue. Usually a 3-5% drain over 24 hours maximum. Apple even less. I upgraded my Apple Macbook pro to a SSD and the battery drain is a touch more than it was w. a standard hard drive but still not more than 3% a day while suspended. I wonder since my T410s has a SSD if it is cause.
What configurations are others members of the forum using exactly? This is my only grievance with the computer and all updates have been applied to date.

Nokia Lumia 920 potential battery drain issue?

Can you Nokia confirm this? http://reach.jdbpocketware.com/topic/128305-to-nokia-ref-lumia-920/
The issue illustrated in detail:
Nature of Windows Phone buttons
Pressing either the power button or the camera button will cause the device screen to turn on, even when the proximity sensor detects proximity.
[IMAGE http://i.imgur.com/M2to9.png]
The lockscreen behavior
Upon power on, screen lights up and shows the lockscreen (or camera), which runs a timeout to auto power off the device if screen is not touched in X seconds.
But if screen is touched, the timeout counter is restarted, so continuous touching could lead into a loop, the "death loop" which won't let the device to power off (standby) and will consume battery life.
[IMAGE http://i.imgur.com/2HNdV.png]
New touchscreen technology
The Nokia Lumia 920 comes with a touchscreen that reacts to touch from pretty much any material such as metal or clothes. This can be dangerous.
[IMAGE http://i.imgur.com/4tbyY.png]
So here is a theory
When the phone is inside a pocket or bag it can be touched by other objects. These objects can press buttons and can touch/rub the screen. This will initiate the "death loop" for who knows how much time, could be minutes or hours, depends on how active the user is since body movement will produce friction between objects/clothes and touchscreen:
[IMAGE http://i.imgur.com/XMT0y.png]
The "death loop" will drain battery and battery is precious.
Solution?
Should be simple: screen must not power on if the proximity sensor detects proximity. Current version of Windows Phone does not take care of this. The big question is: will Windows Phone 8 take care of this? Is the Lumia 920 a potential battery drainer?

I don't understand why we have to spend our valuable time in the forums for days and nights to FIND HOW TO FIX THAT CRAB!! NOKIA company did not handout these devices FOR CHARITY.All of us had paid around a thousand dollars to buy this Phone. They have got to work overtime to fix it and publish a solution otherwise recall the devices back.

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!

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.

My computer shuts down instead of sleeps when battery drains...

Hi there!
So, I just got a new MacBook Pro (the better 15" one) in June. I've noticed, however, that when my battery drains, and the little warning comes up that says "your computer will go to sleep in a few minutes to preserve data," if I let it run all the way out, it doesn't go to sleep but just shuts down. When I reopen my computer after plugging it in, all my stuff is back, but I do have to press the power button and start it up again.
My old computer (White MacBook 2006) always actually went to sleep, and only if I let it sleep for a long time did it shut off.
Have they changed the behavior? Do the laptops only shut down, and no longer sleep when the battery is gone? Or is something wrong with my computer. I'm getting all my data back, and all the windows and stuff are still open, so that's not a problem for me, but if my computer is working incorrectly only three months after buying it, then I'd like to know...
Thanks! Let me know what further information you need to help!

Your computer is not shutting down — it's hibernating, also called "safe sleep". This is indicated by the fact that everything you were working on is undisturbed when you wake it by pressing the power button.
The contents of RAM are written to the hard drive before the machine enters safe sleep, so that if the battery drains completely before you wake it, the contents of RAM (including your unsaved work) won't be completely lost. This is different from ordinary sleep, in which the machine simply suspends all activity without writing anything to disk. If the machine went into ordinary sleep after giving you a low-battery warning and not getting any cooperation from you (i.e. you didn't heed the warning and plug in AC power), and then you didn't wake it for twelve or fifteen hours, the battery might have gone completely dead and your unsaved work would be lost.
In short, yes, this is new behavior compared to several years ago, and from what you tell us, your machine is working exactly as it's supposed to.

Nokia 1020 battery drain rates.. mine typical?

I recently got the 1020.. i've installed a battery app.. at one point, post a MS update that i got through dev channels, had issues with massive battery drain.. around 20 percent per hour..
So i reset the phone to factory defaults, per some threads around here.. also tried running with very few apps.. saw around 3.5 percent per hour after that, at least till i put some apps back on it..
This is with wifi, bluetooth and lte on.
My usage throughout the day is minimal.. no videos typically.. just web page hits or email checks or message checks etc.. i turn the phone "off" / standby when not in use typically.. maybe have it on say 45 minutes out of the day without turning it off.. and the rest here and there for email checking.
A few days in row.. start off with 100% around 9am.. by 515 its at 38-40%.. (the recharge rate varies between 25-40%, depending on which recharger i'm using.. i have usb charge ports for the wall.. some are 1 amp, some 2.. not sure this matters on charging)..
Right now i checked the phone.. it shows a 6.8 percent discharge rate.. i really havent seen anything below 5 in awhile now.. it can peak at 11-14 when doing a mix of web/videos etc for 15 minutes.
I do have 2 active tiles and a lot of things pinned.. maybe three swipes worth to get to the bottom if that..
Can anyone comment on their discharge rates.. does this sound normal.. thinking maybe swapping it at the store if they have them there, before my 30 days runs out.. not sure if nokia warranty goes beyond that or not and i'm guessing no advanced replacement if needed.
Thanks in advance

I have a Lumia 920 that is out of warranty, and has been having battery issues for quite a while. I have to add, my phone is developer unlocked. My phone currently dischrages about 20% per hour, or so it says. I restart the phone, and my battery level goes back up, and basic math tells me it is really discharging less than 2% per hour. I have to reset the phone about three or four times a day. Since it is developer unlocked, I wrote an app using the battery API. There are only a few items you can return from the battery API, the ESTIMATED battery % remaining, and the ESTIMATED time remaining. There is also an event that is supposed to fire when the battery % drops 1%. If you don't understand programming, and event is something that happens in code that when it does happen, you can write code to execute when that event happens. So in my app, I can clearly see the battery % drop, the time drop, but the EVENT never fires. I have had battery apps installed, and they mimick the same results I am getting. Also, they never update the battery remaining % or time on live tiles, which tells me the event is not firing in their code either. I have an open discussion in Windows Phone developer forums about this. I just got a 1520, and am going to try and side load the app without developer unlocking the phone to see if the same behavior occurs. Since my phone is out of warranty, I also tried a new battery, but same behavior. I'm pretty sure this is not a hardware issue, but a software issue, at least in my case. When your battery runs down, have you tired rebooting your phone to see if the battery level comes back up?
