My prime was largely fixed with the latest update (.13).
BT/Wifi: fixed.
Random reboots: fixed (although mine were very infrequent to begin with).
However, now I would characterize the sleep battery drain to be at least double, if not more, than it was with the previous update.
Is this affecting all primes? In 8 hours, I am loosing 30-40% charge while the unit is asleep and off the charger, vs. perhaps 10%, at most, previously.
Yes, some will say it isn't but they just don't realize it.
I left the house this morning with a full charge. I just came out of sleep for the first time today and I'm at 97% so no I don't have the new battery discharge while sleeping feature. I have had 3 unexplained shutdowns since the .13 update where I didn't have that on .11
After .13 update it also took me a while to realize that I was getting "sleep of death" characterized by reboot and battery drain after the prime is put into sleep mode.
I was able to confirm it because I have GoLauncherEX installed and after a reboot, it asks me to choose my home screen. I noticed everytime after I woke my prime up, I would be asked with the choice, indicating that it rebooted. However, since I kept it plugged into the charger, I didn't notice battery drain until I read the forums.
I think in the older versions of ICS wifi was turned off in sleep mode now it's on all the time by default. I changed mine to shut off while sleeping and set it so my e-mail only logged in when I want to check it.
Since the update I've not noticed any significant performance improvements or issues. My Prime will go hours with minimal battery loss when sleeping, has never had the "sleep of death" issue, and does not seem to have significantly better Wi-Fi performance.
I've not had the problems that others on this forum indicate, though. I've been quite satisfied with my Prime.
My prime has the sleep shutdown issues from the .13 update but I have no battery issues. I found out that manually turning off wifi before I stop using my tablet is temping prevent the sleep death issue, and last night it stayed on all night which was about 8 hours and the battery barely went down at all. I actually looked at the battery graph and kinda laughed at how straight the line was since the battery barely changed. It must have went down like 1%.

How can something be wrong with an imaginary device?
Example of battery drain while sleeping.
I have eliminated as much as I could from running while sleeping. I have been watching over the last 4 days and you can see when my tabs screen is off the battery is draining. I used to brag to people how well the battery is when your not using it......I used to get almost a flatline.......with maybe 1 to 3% drop while sleeping. You can see that is not the case sense the .13 update. You can also see something is keeping it awake. This was never the case before the update. I will keep looking for whats causing the tab not to sleep.......

Do not know what u talking about. I said I get great battery life n posted results in other thread
Add me, too to the list of those whose Prime was working great before the update, and now is completely drained dry if not plugged in overnight. I use to get 2 1/2 to 4 days or so of modest use. Now I lose all power overnight, every night.
I hope a fix is on the way.
I havent noticed anything too different for battery drain.
Charged it this morning , 4h, 23minutes ago and its at 97%
It's really an issue, I left my Prime idle all day with the dock attachment, and the dock battery is drained completely after 15 hours. It didn't have this issue until the .13 update.
I wish Asus would just give us back our .11 FW while they work on the issue. It's the least they can do at this point.
My prime has been off charger and on standby for the past 3 hours... unlocked it and...
Dock is 100%, TFP is 99%.
Boom.

You don't know if the update is the real issue.
It could be just like how people thought the update broke the YouTube app (it didn't). It could be very well something else, especially since there are many that don't have the issue, myself included.
I forgotten my Prime over at my sister's house this passed weekend, it was nearly fully charged when I last used it to output Youtube to their TV over HDMI. I'm going to pick it up today and I'll know for sure if this is a problem.

There is zero doubt in my mind that the update is the cause of the issue. This situation is nothing like the Youtube issue (i.e., there's no equivalent of a "server side" problem for the battery drain many of us have experience immediately following the update). Not to mention that the update changed the usage of the cores and raised the minimum clock frequency.
Not having any sleep issues after update. Charged up and unplugged Friday evening and put back on charger earlier today. Pretty much the same as before update
Ill start with the obvious. Screen not sleeping while charging is disabled. System performance is set to Power Save.
For testing I charged my dock and tablet to 100%. Before sleeping I unplugged my tab/dock from the charger and locked/turned off the screen and left it on my desk.
I awoke 10 hours later to a completely dead dock and completely dead tablet. Before my tab/doc were able to standby for several days.
My apps have not changed other then updates from the market. I have also restored my apps from Titanium Backup and blocked the app updates with the same battery loss.
I am going to try to roll back to .11. Once successful I will post new test results.
Also just for point of note, I have never once had a forced reboot on this prime. Wifi works decent with BT disabled as described by others. GPS is fail.

I was playing a game when my phone crashed and locked up. I had to restart my phone and upon restarting my battery is now at 20%. My battery was originally at 85% and I was playing the game for less than 5 minutes. Why did I lose so much battery power in such a short time and is it harmful for my battery?

Your battery did not actually lose all that at once, all that happened is either a change in the way battery fuel gauge is bring reported or a corruption of the battery stats being kept.
Either way a couple charge cycles and the gauge reporting will get back on track.

Not even a couple of charge cycles. The fuelgauge should "converge" within 1-2 hours. To make it converge faster:
Turn off phone
Pull battery for 5-10 minutes to put it in a "relaxed" state (no recent heavy charge/discharge)
Put it back in and power on
Also, what was the raw battery voltage? It's impossible to tell whether 85% was a false-high or 20% was a false-low without knowing the raw voltage.
I have left my sgs off for a few hours now and it hasn't made a difference. I just got home and plugged it into the charger and I will wait and see what happens...
I've had the same thing happen to me this morning.
Phone was Idle, full after being charged overnight.
I was checking the web to make sure I had all my ducks in a row before
loading up the Unammed 1.04 ROM.
Tried to wake up the phone, nothing.
Tried holding the power button a little longer, nothing.
I plugged it in and tried holding it longer yet, finally.
Phone crashed itself but hard.
Woke it back up with a heavy dent in the available battery.
Dropped something like 60% over the course of an hour or less?
I was just about to panic.
Added some more juice, while I made my backups and copied in the new ROM.
I'm not sure what that was all about.
I've had this happen recently...

I had this happen once. I plugged it in after the battery level plunged some 50% after an app crash. But as soon as I plugged it in, it seemed like it started correcting itself. The charge level would go up by a couple of % points every minute and converged to the right value within an hour or two.

Happened to me last night. Went from 30% to 12% after a crash/restart. You can see the small bit of red on the right.
So does anyone know for sure if the battery actually drained that fast or is it some kind of glitch?

It is not physically possible for the battery to drain that much that fast. Now in an extreme battery failure you could lose that much capacity, but that were happening your battery would be pretty much shot. don't worry that is not happening to you.
The fuel gauge reporting just got reset and if it was off before it will be closer now. If it is off now, it will work itself back out very shortly on its own.

I would agree with the above. It was annoying but I'm not yet very.concerned. if it happens again or becomes a regular thing then I'm going to be a bit annoyed.
I got my sgs2 2 weeks ago, today I noticed something weird:
I unplugged my phone at 9:15am (100% battery), and at 2:45pm it was at 10%. I am not sure why it died that fast.
I am using some app's which need to be synchronized, but I dont think they can cause this. (FB, Email, Weather). please advice.
How about this usage after installing a new Rom and a theme.
I do think it's the theme I have applied, but it gets too hot too even not being used. I'm not sure what the Rom is, I am using the one the phone comes with.
My phone did this last night for the first time, Ive been catching dolphin browser using a lot of resources. I forgot to kill it last night, battery dropped 50% in 2hrs.
I have removed the theme I had applied and it came to normal already. But I am concerned why it did happen, is it not supposed to support themes like GoLauncher?
Only worry if the problem persisted. Use the battery then charge it full. You likely won't have any issues.

I noticed the same thing with Dolphin browser and if you go into settings and activate the Google or Facebook accounts to be used in conjunction with Dolphin that it will put your phone into overdrive and heat it and drain the battery in about 3+ hours...So I would avoid using this if you like using your phone the whole day!

Is expected to have the phone hot during charging? I am charging it now and it is getting hot even though I am not using it. I am really worried about this.
Please let me know if this is a normal behavior or if it's not.

There's already threads discussing safe charging temps. 50°+ celcius is bad and 70° is deadly to the battery. Phone can handle much more. Download a battery temperature app.

I got my S2 a few days ago and flashed Cf-Root and the latest checkrom a couple of days ago. I knew battery life was a big issue with S2 so i thought i'd check how mine was performing.
I left the phone charging through the night and after unplugging the battery is down to 80% after just 5 hours. What makes things worse is that the phone has been unused for about 95% of that time. All i've done is send one SMS and flick through my settings a couple of times.

Display being 44% is puzzling since its only been on 30 minutes at about 50% brightness. Android OS is 39% and when clicking on that it says it has been used just 22 minutes (CPU total).
I a real S2 and Android noob so i really have no idea whats going on. This cant be normal surely?

Your display has used 44% of the power used = 20% total so your display in five hours has used about 9% of the battery .
Search all the battery posts and read them for clues .

Heya, I see that you have WiFi on pretty much and that's quite a battery drainer. It shifted my battery consumption from 1-3% while sleeping to a whooping 25+% (about 6-8 hours of sleep)... make sure you turn off wifi and data services when you're not actively using your phone

After doing some reading one thing that may be causing this is not calibrating my battery.
When i received the phone it came without about 60% of charge so i just plugged it straight in to my PC figuring i'll let it charge to full while i play around on it. Unless i'm mistaken this was a bad thing to do?
I've downloaded Battery Calibration from the market and i'm currently waiting for the battery to charge to 100% before running it. Hopefully it'll help things.

The best way to calibrate the battery is to actually charge to 100% (make sure the phone is off) then unplug the battery for about 90+ seconds, then plug it bin and use your phone normally until the battery is depleted to 3-7% then charge fully. BTW I HIGHLY doubt that's the PROBLEM.

So once i've calibrated the battery and find that that isn't the problem how do i go about investigating what is the problem? I'm far too much of a noob to work it myself
I'm considering flashing back to stock firmware and seeing what happens with that.
Reading numerous threads on these forums I've found out that there is absolutely no need to calibrate the battery in SGS2 with any external programs / processes. The battery calibrates and maintains itself during its lifetime (something about a controller chip being integrated inside them).
If I may recommend, flash SiyahKernel , apply the battery optimizations through CWM (install zip from sdcard), and just work normally with the phone for a few days, making sure you remove all unnecessary applications and turning off data services whenever you don't use the phone.
And if you still get about a day of battery with moderate usage, it's very good for you... the stock battery just doesnt live that long with the powerful hardware that is in the phone
I would like to get some more information on the WiFi battery drain problem after the .21 update. Some users report decreased bat life due to WiFi, some see no differences. Would be interesting to see what the magnitude of that problem is.
My WiFi performance is increased by at least one bar, but battery life is decreased to 6h screentime...
My battery drain is massive after the .21 update, and 100% down to the Wifi (in battery stats)
They have obviously turned up the power but i cant say as ive noticed a massive difference with performance.
Yesterday i lost nearly 20% battery in the space of 30 - 45 mins.
I mentioned it in another thread. Support told me that there is an update on its way. Whether it will solve this issue or not, he couldn't say.
Yes, Gary updated one of his other threads, we have an update literally just around the corner. Also we may actually gain use of nvflash!
Anyway, back on topic, yes I've seen some increase in battery consumption, but I don't think it's as bad as some of y'all. I can leave my WiFi on 24/7 and still use my tablet for at least 3 days.

What makes you say we may gain NVFlash access ?
Had my prime hooked to my TV going through tobuscus's videos on youtube while I was gaming yesterday. Went from 100% to about 30% after ~5 hours. Not bad especially streaming 720 videos
Sent from my ADR6300 using xda premium
There definitely is increase in battery drain since .21
To say it's the wifi, i dunno...
Yes. the wifi, according to the stats, is the biggest battery drain, but seeing as we haven't had these battery stats previously, we can't really make a comparison on that.
For me i don't see much difference between wifi on or off.

We are still validating a new firmware release. We are also tracking user reported issues with Tegra 3 games, WiFi Direct and some continued random reboot/lock problems with a few units. Based on current regression testing at HQ, NVIDIA and Google it appears we will need to sway out a few units to pinpoint exact user problems. For the unlocked audience, we have requested a version of NVFlash that works properly for users who unlocked their units.

Wifi was definitely affecting me. Bat life was dropping really fast. I now have wifi off when on sleep and the battery literally lasts forever. Been playing road warrior for a couple of hours each night some web browsing and you tube playback oh and messing with the ui. I still have 71% battery after 3 nights. Dock not even plugged in. Drops maybe 1% over an 8 hour night if that now. Was about 10% with wifi on.
Oh and when using its in performance mode, switch to power save before sleep.

First thing I noticed after the .21 update was the battery drain not an improved wifi signal. Factory reset mine. Same deal, now I just keep it in the dock while I'm out on the road.
I actually see fastest battery drain using the dock. NvFlash would definitely influence me to unlock my tab but def not before I know it works for most bricks.
I'm on a .21 ROM and my battery life is awful. I lose about 30% overnight while it's sleeping.

you have something else going on in the background to drain that much. i never heard of such battery loss while a device is only sleeping overnight. You better get the app here in xda called "better battery stats" to see what's really draining your battery. seriously doubt its wifi alone doing that.

I have "better battery stats" and it clearly shows that most of the drain is due to WiFi. There is a handful wifi processes which draw power.
I also recognised something else. Over the weekand I stayed with a friend. The battery drain on Wifi was back to normal over the weekend. Back at home WiFi sucks battery again.
I assume the Prime-Router type must have something to do with it.
I have a WRT350N at home.

Batterydrain and charging issue!!
I'm also one of those whose had a flawless Prime until the .21 update.
After the update I almost immediately experienced one "Sleep of Death"
that a soft reset fixed and that has actually not occured again.
Two other things are killing me though, after the update and the "SoD"-
incident I have terrible battery time and the tablet will only charge via
the keyboard-dock. If I insert the charging-cable to the prime itselves
it recognizes the cable and the charge indicator lights up red but I don't
get the lightning symbol on the battery status and in settings it says it
is not charging. If I put it to sleep for a while and wake it up again I get
the lightning in the battery icon and it says charging in settings, but it
charges so slowly I recon it would take 3 days to charge to 100%
I have RMA'd it one time but the useless guys who had it for 14 days just
changed the USB-cable and said it was A-OK, still nothing had changed.
Don't want to send it back in, tips and tricks would be much appreciated.
Thanks

that doesnt show anything. Wifi and display will always be the biggest battery drainers. plus the battery reporting inside prime is flawed. you need an app like better battery stats to show you whats really going on. my prime shows the same thing, as wifi being biggest drainer but i still get great battery life. from what you reported earlier, something else is going on in your prime you not aware of to lose 30% overnight with prime just sleeping.
I think I was one of the first to notice & question the battery drain after .21 update. Mine isn't as excessive as some are reporting, but it is definitely noticeable.
For example, before the .21 update... during sleep/overnight.. with WIFI never turned off, I will see perhaps 2% decrease in battery at most.
However, with .21 update... during sleep/overnight, Prime will lose about 8 to 10% in battery %. So, it is about 6 to 8% hike in battery drain during "sleep" stage.
I haven't tested or examined the battery life difference when it is being used.. as that's a bit more difficult to gather data based on my use...

i think you was. Its so hard to gauge and compare everyone's battery usage. Everyone has different settings used and different usage. I heard one rumor of Asus possibly increasing the wifi power for better connection/range. It was never confirmed nor denied. I never mentioned this issue before. I can try to dig up info on it from Gary and see what i find out. We have an update due to come out any moment now so we all need to see how battery performance is after that. I'll see what i can find out. Asus has been having trouble recreating the issues alot have reported. which makes it hard for them to fix if all their units they test never show the symptoms. For other software related issues, more logcats may need to be done and sent to asus. for ex. they haven't really been able to recreate the games crashing/freezing issue. Same with wfi direct. all their test units seem to work fine...lmfao new update is supposed to address some of these issues and more.

For other software related issues, more logcats may need to be done and sent to asus. for ex. they haven't really been able to recreate the games crashing/freezing issue. Same with wfi direct. all their test units seem to work fine...lmfao new update is supposed to address some of these issues and more.

Eh, really? Wifi direct is completely worthless/useless to me atm (as in, doesn't work).... and to those who actually got it to work (based on their comment), it seems half-assed integration. Wish I have one of their Test Unit... seems/sounds perfectly functional (void of any of the issues/problems....).
Btw, don't take offense to this... but I have to ask...
1. Are you the unofficial spokesperson for Asus now? It still amazes me how they continue to respond to you & yet, I keep reading those with "issues" are yet to be contacted.
2. Did you have the authority to release/leak GPS dongle information? Such as leaking the photo a day before to Land of Droid for your 15 min. of fame.
My battery is quickly dropping according to my battery stats it's android usage. I did a search but only information for the SGS3 pops up. Anyway I can find out what's causing it?

I'm having a very similar issue. I thought that screen was suppose to be the largest drain, but Android System appears to be consistently 55%+ of the battery used.
mine usually doesnt go above 20%..
its on screen percentage that is killing me lol
I wonder what's causing it.
My main usage on my S4 is the screen.
LOL Tap in the Android System in that list and see what all is listed under it. If you are running everything that Samsung added to the TouchWiz like the air view and eye tracking and such you will have the System draining your battery. Find out what you will actually use and not use and what is more for play turn off and what you will use regularly leave on. My guess is most ppl will have most if not all of it off on a normal basis
My S4 i got today from VZW i had some gestures on charged it to only 74% by noon (had to go out) and 5 hours later with just under 3 hours of screen time i was at 63% battery still and screen was 65% in the list with Android System at 12% Also screen was at 35% though not at brightest level.

Mine is showing only 5% over today. Screen is my biggest drain (as expected). Does it remain high usage after reboot?

Oh ok. That's what I was confused about. It was fine yesterday and then today not so much lol. But I did disable some of the gestures to see if that makes a difference. Thanks

a little update. I have seen this as well now but only after charging to full. It was not doing it yesterday cause i didn't get a chance to charge it to full until later last night. I was in and out since picking it up yesterday morning and never got it past 80%. So here is what i found.....
Once full and I unplug the phone (from the wall not usb charging obviously) the Android System is in the 50%+ of battery consumption in just a min or 2 from unplugging and seems to stay there. So after a few times of letting it get to 96% or so and recharging to check after an FDR I decided to just unplug the phone and reboot right away, the Android System never gets above 9% in the battery stats list when i reboot immediately after I unplug the phone.
Anyone with a reason why after charging, something in the list (and it's a HUGE list of apps at that) making up Android System is hanging after a full charge cycle? I mean technically, it's not a bad thing to reboot your phone each day but should you HAVE to do it?
Eric
Click on the android OS. Is it keeping your phone awake for an extended period?

Not sure if it'll show up, but it's eating up 65% of my battery :/. Not sure what's causing it.

Unless you are seeing your battery yield horrible life this is completely normal. Because its telling you a percent of the loss, for example your battery is at 90% so its showing you the break down of the 10% loss. So your screen is 70% of that batter loss. The screen is always going to be in the top. Thats good honestly that shows that you dont have any apps sucking down your battery more then the most power consuming hardware (screen)
My Android usage is high too. 60% is weird. I've frozen alot of stuff and only a few gesture options enabled. Would like to figure this out myself

After 3 wipes of device and also an sd card wipe I was still having android system double the power consumption then the screen. I wiped the phone and then didnt log into google and just used the web broswer and surfed for 40 mins and then checked the stats, android system was still the number one even with 40 on screen minutes. At this point I was done with this phone
I just went to verizon, the manager first tried to tell me it was because I have location settings on, then I told him that I had the issues before I turned them on. Then he tried to tell me it was because im not using power saving mode. I had to almost fight for the exchange, he finally pulled out his phone and googled it and saw that this is a known issue and then tried to tell me that because its known that I shouldnt do the exchange and wait for an update, I said no. After 2 hours I finally walked out with a new s4, I will see how this goes.
I too am having the same problem

Wow. While this issue is somewhat annoying in the fact that something is there somewhere doing something in the background, it is not something that can be hardware related. It is just something enabled somewhere that we havent pinpointed yet. Regardless, I get great battery life and have just learned to deal with it. I know when some more roms come out and more things are figured out, it will be fixed. Its nothing to go ask for a replacement for. Not trying to sound like an a$$. Just saying
Sent from my rooted Galaxy S4 via tapatalk 2.
tell me this then, if its software then we should all have the same issue, because we are all on the same build (minis the rooted / rom installed) but of the 5 devices that I have looked at only 2 have this drain? I had done a factory wipe and then DIDNT log into google, or samsung so I had only the original installed apps, and I still had the issue,
So the only real way to test it I guess is we need to have someone that confirmed doesn't have this issue they will need to make a ODIN restore and then someone with the issue needs to restore with that, then that will eliminate any possibility of hardware problems.
I see your point. I did find something in better battery stats though. On partial wake lock, there is a process called audioout_2 which had used almost 45 minutes of cpu. Clearly, by the name, it has something to do with sound output and I then realized that touch sounds were enabled on my keyboard. Hopefully disabling that helps. It may not be the whole problem but I'm willing to bet it has something to do with it.
Edit: I checked the cpu time after I turned off keyboard sounds typed alot of random letters for about 20sec then turned sounds back on then typed again for 20sec. Checked cpu time on audioout_2 and it increased that same amount of time like I thought. So I'm going to see if it helps.
Edit again: my android system usage is slowly dropping. From 67-63% in the last 20 minutes. Won't know how much it impacts it until a recharge.

Do you guys with the high android battery usage have the Verizon ongoing connect to wifi notification? When I had it my Android system was high now that I managed to take it away is gone down a lot

This phone has infuriated repeatedly. I was content on not ever leaving Jelly bean (kind of), I was happy when root was discovered, but what I loved the most was the fact that I could go 3 full days without the need to recharge,. Now, I seem to be charging the phone 3 times a day. I am probably exaggerating but still, none-the-less it isn't good.
My battery life status is NEVER correct. Then, when I usually get around 52% the phone says it is out of charge and completely shuts off. I have a rooted device and use Tasker and other similar apps heavily.
I emailed the Huawei directly about a possible defective phone and they pretty much blew me off.
Never again will I go with the Huawei company. So much fail.

I had an LG phone in the past with a similar problem. At first, I thought it was a battery problem. The phone reports 100% after 45min. When the charge drops to 80%, I get a warning that the phone is out of charge. I got a new battery, charged it elsewhere and used it on the phone. Again, same problem. I was really baffled. I reflashed the stock rom because I thought it was a software issue. No luck. I then threw away the phone, forever oblivious of the cause !!

I'm thinking it is a defective battery. However the HAM2 doesn't allow the battery to be swapped out. I am so frustrated I want to toss this phone in the trash too.

It sounds like the phone itself isn't reading the battery correctly. The calibatration is off.
I'm still new at this, but may be others on this forum have some experience with what I'm about to suggest.
- Have you tried backing up your phone's data and then doing a factory reset. Once the factory reset is done, just use the installed apps and UI for a few days including checking to see what apps are running in the background and on startup while you draining the battery completely to dead, then leave the phone to charge to 100% over night. That most likely will unroot the device too, but you can always just install TowelRoot and root it again like I did and then install SuperSU, BusyBox and Terminal. Now see what your battery does. Its not a guarantee its going to fix it, but many manufacturers do suggest factory reset.
I'd take it back to factory default, don't install anything and run it a full charge cycle down to cutting itself off, charge it, and check it the 2nd time.
Sounds like you have some sort of massive wake lock going on.
I've had mine since early July...no issues. NOT rooted, 100% stock rom.
Something similar happened here (twice). Yesterday, after 48+ hs of continuous use, the battery reached 15%, and suddenly dropped to 0%. "your phone will shot down in 30 seconds" and it turns off. And another issue, it seems not read the consumption when connected to mobile data connection. What can happen here?

I have had my phone since the release and still get 2 days out of it on normal power profile. turn your stuff off on protected apps and if still nothing return under warranty from Huawei.

I thought that was some sort of safety feature built into Android to save enough battery for emergency calls?
I still have my System UI crashes, and on top of that, I get some gapps package crash error and a few others. I'm waiting until after my last final exam on Monday to reset the device and see if those still occur.
I was at 4% last night then I plugged in. you using 2amp charger?
UPDATE:
It appears it now works correctly since I started using the app DS BATTERY SAVER PRO.
Thanks for the update. So curious can you now disable/uninstall the app and see if the problem is gone. Still feeling it is some battery calibration got screwed up.
