I just noticed in the past few minutes that my gmail is pushing to my tablet despite the screen being off and my wifi policy set to off when sleeping. I've also found some issues when it would actually cut the wifi off when sleeping, and when it comes back it doesn't want to reconnect to my router.
My other issue is battery life related. Last night I *believe* I turned airplane mode on before going to sleep and when I woke up 9 hours or so later, the battery was at least 10% down, I think more than that but I didn't take note of it at night. Even if wifi was on, it should've been shut as my sleep policy is that way. Looking through other threads people seem to be experiencing 1% or so battery drain in an hour. The other factor is that I have setcpu installed and a screen off profile that maxes at the second lowest frequency. This morning I installed netarchy's kernel and lowered my setcpu profile so it stays at the minimum frequency when the screen is off.
I'm running Prime 1.3 (didn't do the r2) and have manually removed a handful of the Asus apps that I don't use/want, and I have GPS disabled.
What 'concerns' me is that I have a droid incredible for a while now and with it, I get no battery drain overnight with airplane mode on (at least none that registers) and that's a battery with a fraction the capacity of the transformer. Moreover, I have a very few apps on my tablet whereas my phone has quite a few and basically beyond the stock stuff on the tablet the same apps are on my phone. Also, the battery stats window on the transformer doesn't show any info about apps. I've had my phone on since I woke up, on 3g and I'm at 90% with not much use. And I thought that my phone got meh battery life.
ive had some issues with wifi disconnecting and wouldn't stop disconnecting till a reboot. cant find any news on it. ive tried all firmwares now and still have the issue.
I been having the same issue. Last night I reflashed the 8.2.3.13-20110511 build, to see it it will help. Mine is stock not rooted.
I have the dock and use the pad with most of the time, both are loosing battery life even after I do a complete shutdown. To me it seems it has gotten worse after the 8.2.3.13-20110511 build update. The WiFi is loosing connection when the dock goes dead so I have to reboot the pad to get it to reconnect.
I also have contacted Asus tech. On another thought I really wish in Android you could disable startup apps without rooting.

Was hoping for more replies but my naturally long-winded posts probably scared everyone off...
I wiped my device and installed Modaco's ROM. I didn't touch the stock apps and only things I've installed are Titanium & Tasker. I put together a Tasker profile to kick airplane mode on when the system is put to sleep, and turn it off when unlocked (unless airplane mode was enabled when put to sleep). I also installed Setcpu and setup a profile to keep the CPU frequency to the minimum when screen is off.
I charged to 100% and let it sit overnight. When I woke up I was at 98%, when I got home a little while ago it was at 96%. Note that I hadn't used the tablet other than for a brief minute or two to check the battery stats. As of now I'm showing 15hrs 51mins on battery with a 4% drop. I've had it in airplane mode the whole time. Oppositely, I had my droid incredible at 100% and played Drop7 (great game btw) for at least 20 minutes before going to bed last night, and it was still 100% when I woke up (it was in airplane mode overnight). I find it weird that my droid incredible, with a 1/4 of the battery capacity doesn't drop at all overnight even with a game being played, and the transformer drops 2% in that time idling.
Has anyone wiped battery stats via CWM?
When I setup AutoStart, I noticed the power state event for screen on/off is off by default. I tried turning back on, seems to improve battery on sleep.

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

OK cool, I wasnt sure if this was a general issue or not. Can a Mod move it? Or should I just delete and Remake?
Ive looked in spare parts and Im not sure where it would give that information, under battery history ive got running at 38.2%, screen on 25.2% phone on 14.5% and wifi on 100%
nothing mentions sleep mode

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

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

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

So I know this update was supposed to make battery better, but I am getting big time battery drain after updating. Are there non root methods for finding what spa are holding wake locks and draining my battery? It seems weird this just started after update...
For reference this is at least 10% lower than I was at the same point in the day before update, and it has been several days since update..
Was missing two images
It looks like you got no bar to one bar of LTE cellular service. That will drain your battery big time.
That was temporary. See big green mobile signal bar in battery usage. Again, totally same conditions as before update. I found some instructions to run wake lock detector without root. I'll try that.
Fixed... Was yahoo weather app.. Not sure if it was just glitched or what. Uninstalled now 7-9 mA drain on idle.
So, I have noticed an increased drain on my phone's battery since the OTA 8.1 update. But these last few days it feels like it has been getting worse, even with battery saver mode on, no background activities and rooted Greenify. Today it drained 3% of battery in less than 25 minutes, battery saver on, no Wi-Fi n but not connected and mobile data off.
Somehow my old iPhone 5 has better battery life than this one. Also, the AccuBattery app I installed says the phone has already lost 10% of the battery's original capacity.
Am I the only one who has noticed this after the update? Have you guys felt that this has been happening as well, or am I just paranoid?
And do you happen to know any good apps for checking battery health besides AccuBattery?

Ok... Just stop for a second...
I learned a thing the past few years about Android...
Looking for battery... Actively... Usually sets you up for higher drain...
Do this...
Put everything back to stock... Then take out the stuff you'll never use... Like... WiFi/Bluetooth scanning (if you don't live in the city)... Turn Bluetooth off (if applicable)...
Then... Make sure you've trained everything... Like Ok Google... Then turn it off if you don't use it...
If you're not on Sprint... Disable anything Sprint related in apps... To make sure they don't receive the ON_BOOT intent...
Then... Don't reboot unnecessarily... You'll get better battery the longer the device is booted... To a point

Noticed that lately as well, resetting network setting fixed it for me YMMV
Just reset everything, also flashed back to 7.1.1
Just deciding now if I should sideload the 8.0 or OTA update to 8.1 already to see how it will respond. Will discard everything but the apps I commonly use
make sure you do not disable WiFi IF you have WiFi calling enabled... causes wakelocks during idle/sleep which drains battery.
I have this weird issue. It appeared around Christmas.
I tend to leave my phone with wifi and data off during the night.
Since about a month ago I get a huge drain when I do this. About 3% or even more per hour. I may lose 20-30% when I sleep.
No Ambient Display on, no data, not anything else.
Phone signal is excellent and moreover this drain does not happen when I leave the phone with 4G on. I lose about 1% or less. It's only when I disable data-wifi. I also tried with airplane mode on and drain was minimal. With wifi on, I get some drain but it's acceptable (my router is a bit far).
I used both BBS and GSam and I cannot find the culprit.
It doesn't have anything to do with any 3rd party apps and wakelocks are minimal.
I get RCS Phone as the top drain. I know that this replaces the Android System in some cases, but I'm wondering that maybe it's the RCS Service or something (because it got an update during December and the problem appeared around then).
January update did not change anything. Drain during normal use and the rest of the day is pretty normal.
Any ideas? Anyone else that may have experienced something similar?
