[Q] Poor battery life with Team EOS 2.0.0 - Xoom Q&A, Help & Troubleshooting

Hello!
I am experiencing very bad battery life with Team EOS 2.0.0 rom. Earlier when I had 1.0.0 the tablet could go 2-3 days in standby but now with 2.0.0 with the exact same setting it can hardly go through a day! I have not changed anything, I have email on push, pulse news to be updated every 3 hours and that is pretty much it. I also set to keep Wi-Fi on during sleep NEVER, but it didn't help at all.
Can someone please help me?
Thanks!

I went from 2.0 to nightly 110 and I think that improved it. It'll take me a week or two to be sure but you might consider it. I can't be sure it's hard to notice a trend like that, it could be the placebo effect.

Try calibrating your battery, first let your battery drain off entirely! Then plug on your charger and wait until the white light turns green... After that, enter in recovery and select Advanced-wipe battery stats-reboot system, plug off your tablet and when it turn on, see if battery stats is at 100% or 99% if not at that numbers, do that again. After it's on numbers like those it's calibrated and ready to have good battery life I recommend doing this once at 2~3 months

Sorry, I forgot just one little thing... Don't charge it up until it's drained again! Then it's finished... Now it's AOK

Battery life
In my case with 2.0.0 I was not getting much deep sleep. You can use CPU Spy to see it. So even sitting in a bag for hours, with WiFi off, it would drain at about 1%/hr.
I upgraded to nightly 0.98 (newest Stingray) and now the problem seems to have gone away.

Need better Battery life!!! help!!

hey im using leedroid v1.3 and the battery life on my phone is horrendous, i left the house at 11am this morning with 98 percent and after a 10 minute phone call i had 75 percent battery by 12 oclock. do you guys have any tips or things i can flash to get the phone through a day and a half or even 2 days somehow?
also having an issue with the speakerphone, its the lowest volume of any phone i think ive ever owned, ive got to put the phone to my head, so its basically like making a call but using the back as an earpiece. thanks for the help.
I'm having the same problem with my phone, on any rom. According to CurrentWidget, the Ma being used by my phone will not drop below 150, even while idling. I'm starting to believe that my battery is faulty.
Are u guys calibrating the battety?

I thought I was, but apparently I'm not. Can you point me in the right direction?
Download the battery calibration app from the market. Charge to full run the app calibrate.....drain than calibrate again and you should be fine.

Upgraded to v2 and ran the battery calibrator. Phone finally lasts a day. Thanks. Am I supposed to run the calibrator at like 10% or should I let it die and run it after a 100% charge?
Battery calibration + managing screen brightness massively increases battery life. You need root to be able to clear battery stats, right?

I believe the calibration tools want you to use them at 100% charge. I got a chichitec 1900mA/Hr battery, calibrated (i guess it is now) and my phone went for more than 24 hours before hitting the 49% mark. This was with light use (checking email, checking web forums, playing some Angry Birds, and making some phone calls) but still a HUGE difference from the stock battery. Also, I turn off data connection via quick settings when I am at home. I do turn on wifi though while at home. Calibration ought to help out big time, as these phones are reporting a dead battery long before it is really dead.
Also, dont pay attention to the current battery monitor's report for standby current. It isnt accurate.

That's the one reason I keep going back to the stock setup I just seem to get better battery life out of is than any of the custom ones I've tried. I've only tried a couple. Has anyone found a ROM that gets better battery life than stock?

Terrible battery life after 3.2.1 update.

Hello All,
does anybody noticed the increased power consumption after the last official update (3.2.1)? Below is my battery chart after just one day. The most interesting part is when I didn't used tablet in last couple of hours, as you can see no WiFi, screen, pad not awaken and... battery draining as hell. On detailed battery usage screen Android OS was on the top with 38% then WiFi 15% and screen 12%
Before update battery life was ok (My TF is early hardware, stock OS, no root etc.). After update I didn't changed anything, same configuration, no new software, updates etc. Just rebooting two times because tried to get rid of another 3.2.1 bug aka "mobile browser"
I appreciate that Asus is quick to pushing updates to TF, but this time they did it too fast.
Does anyone have a similar problem, or is it just my update went wrong?
I get 7 hrs of hardcore usage, as for a day odds of charge, lucky u, how long where u getting before cause im impressed ;-)

But to satisfy your curiosity, I had around 7-8 hours of continuous use with WiFi and screen on.
lol sorry for not reading properly, i only got my eeepad on sun and updated straight away to 321, so its all i know at the mo, iv also got a b70 so im patiently waiting for root,

You are going to want to charge your battery to 100 and use the battery calibration app in the market...called battery callibration. Do the instructions it tells you.
You might want to install CPU spy and see what is running in the background to drain your battery like that.

This is a real bug. Here's a screenshot I just took from my tablet. Tell me you don't see something strange with Android OS taking up 26% of the power.
That's 83% battery life left over 4 hours of me using it for about 30 minutes total.
You may want to observe the non-sleeping time using "cpuspy" from Markets. Quite revealing...

Can you see the actual apps or processes running with cpuspy? All I can see is a horizontal bar graph with percentages of different frequencies

You are right. No apps shown. But it shows a bar indicating the duration the cpu spent in deep sleep - this is useful for me.
Sent from my Dell Streak using xda premium
Right...that's part of the problem with the new firmware..it never goes into a deep sleep. Not sure if it did previously, but the battery life since 3.2.1 is definitely bad
indeed i've seen a noticeable drop in the battery as well and was beginning to worry. hopefully someone comes up with a solution
I have no issues with battery drain after updating.
Did you double check that GPS didn't get enabled? Have you tried a factory reset after updating? Yeah, I know it's a pain in the ass, but it's not so difficult to get everything running again after hard resetting.
Regards.
Hi, I've noticed the same battery drain since the update , just bought the keyboard and was enjoying the added battery life ,but last night the pad and keyboard drained flat in seven hours while it was meant to be sleeping like me. It seems looking at the battery info that the wifi and system never shut down and does'nt even when charging :-(
Sent from my Transformer TF101 using xda premium
@CalvinH ,
Good points to check, but I was wondering if you are using the keyboard ,and that is perhaps why some people are not having issues,could it be a keyboard bug again. I will try without and see if there is any difference.

Battery life has not been as good and also when playing music with google music it freezes sometimes and reboots wtf asus
I am getting random reboots as well, after 3.2.1 update. Twice now while the tablet was just sitting there on the table, suddenly the ASUS boot logo pops up.
I have always had problems with ActivityManager killing background tasks a little too aggressively, and so I wondered if it was killing things it shouldn't, now and then. (It does occasionally kill the wifi supplicant process, which should never happen.) But the reboots never happened before the latest update.
My battery life is significantly worse since the update. Before, in 12 hours of sitting idle, it would go through about 20% of battery. Today, it went through 70% in 13 hours of idle.
Wow sorry to hear that guys. For once mine has good battery life again! It was good, then after the last few updates it was reaaallly bad. Now it can go days, but it seemed like it got better right before the update?! Either way its better now.

[Q] Odd battery issue

Hi everyone, and merry Christmas. I have an odd battery issue that has been driving me nuts! Every night when i turn my G2x off I lose between 15% and 45% if my battery life. I know this is not an issue with my battery because if i turn off my G2x and pull the battery out when i put the battery back in in the morning the won't even be one percent lost.
I have had this issue on multiple rooms and with multiple kernels. I have had this on EaglesBlood, cyanogen, weapon, and miui. I have had the stock cyanogen kernel, trinity kernel and faux123 kernel. The only time i haven't had this problem was back before i rooted my phone.
Any help you all could give would be much appreciated. Thanks all!

Note the battery charge percent, pull battery, put it back in, let sit overnight, turn on, note battery charge. If it discharged more than a percent or two, phone is probably faulty because it is drawing current when totally off.
This actually happens to me when I leave it off at work for a couple hours. Confuses me as well...

Phone must be drawing current while it's off, which I am pretty sure is happening to me as well. Damnit.

It is obvious that shutting off from the menu isn' t doing what it should, completely shutting off the phone. Backup your ROM then install a vanilla ROM without any additional apps, note battery percent then shutdown from menu and leave overnight then, in the morning boot it up and note if the battery drained. If it didn't, the problem is either an app or the kernel or rom you previously had installed.
So i temporarily went back to a stock ROM and it didn't seen to have the problem. Which sucks because i really don't want to go back to stock....

Battery drain

My desire s battery drops from 100% to ~15% after about an hour of surfing with edge mobile network.(with different roms) And my friend tell me that this is unusual. I have tried calibrate the battery with the battery calibrate app and it didn't help . It's there anyway to solve this such as flashing baseband?
Thanks for helping.

first open battery usage and investigate which app eat a lot of power.
sometimes just restart the phone will clear out the issue.
The app which eat many power is the browser but I have tried other browsers too but same problem happened.
I have restarted and flashed tons of times and ROMs but same happened.

- which rom are you using? official or custom ?
- try to restart phone, donot open any browser and see if the battery still drain?
I tried cm stable, miui stable , HTC sense ROMs. It only drain when I surf with my edge mobile network. If I use WiFi its normally draining , about two to three hours.

if problem with different radio, may be bad coverage in your location?
Try to move to another place with good coverage and give it a try
As i remember i never flashed the radio. Can u suggest which radio should i use?
Does baseband affect the battery life? If yes l, which baseband should I flash? Thx

- firstly check to see what radio version are you using now?
- make sure your phone was rooted when calibrate battery. Is it rooted?
serious battery problem
OK, I have a serious problem. I updated official RUU, and my phone is running smooth. Battery lasts 1-2 days, everything is working fine. But last night battery was on 17% and I put it to charge at 12pm, woke up at 6am and it was on 33%. I'm charging it right now and it's up to 41% then drops to 39% and so on. Tried another charger - same thing. It won't charge! No new apps, no new settings, battery stats shows the same power use,.... Battery health is good, Auto sync is off,.... I have Go Power Master, Juice Defender, shows no problems. 3G is off, it's on GSM only, Wi-Fi is off, GPS is off and so on, my phone is fully optimised and this happened last night. I charged it while off and now it's on 37%! So I guess it's not a software issue. Anybody has an answer or a clue what could be the problem, please? Is my battery dead (year of use)? Thanks in advance.
try to restart your phone?
Tried that. I'm currently charging it power off, turned it on and it's still draining. While it's off!
i guess it's battery problem. Borrow another battery from your friend and try again.
Well, it was a strange thing... I've noticed that GO Power Master is killing like 25 apps and prolonging time for some 2 and a half hours when you hit optimise button every 2 minutes. So some apps are running in the back and draining the battery. So I uninstalled some of them (clock widget, Noom, Zoner antivirus,...) and restarted phone and by the end of the day it was all stabilised like before. I don't know what happened. I'm still testing it but I've managed to charge it to 100% and there was no drain over night. We'll see.

Noom
I have a S2 and every day, at 20:00 the phone starts a process and gets very hot and also drains the battery.
I discover that if I freeze the Noom app, it doesn't happen.
So, I blame noom for your draining issues and mine.
Does anybody else having this problem?
Regards
I didn't had a problem since uninstall, but it happened again later, I think it was from Firefox. While it was on charger, I got popup note saying something like "phone is using more than current can deliver, try to kill some apps or turn phone off while charging." First time I see that note. Probably because it was on Sense, not on launcher. I've noticed that Firefox is using a lot of memory, uninstalled it and it was all normal like before.

I had this problem, but svery time it was solved with rebooting. It showed normal percentage. I think, you just need to reboot device sometimes, may be once in two days. I suppose to think the couse of ghis problem is a kernel) it can be engaged with not an exact process, so battery drains. Try to change kernel, or rom, or battery)

Lost about a quarter of my battery life

Hello all,
I have had my 8013 about a month now...
It has gone from have over a day of charge to about 3/4 of what it had.
I haven't let it run down and top it off whenever I get back to my desk.
Did I accidently overcharge it and damage the battery or should I do some recalibration?
I see there are recalibration utilities in the store, but wanted to ask before making a situation possibly worse.
Thanks

I have the same question as you!
I can't tell if it is more hardcore/prolonged use over the holidays causing me to think my battery smaller... or if its actually happening...I definitely THINK i notice a difference!
Try using better battery stats and cpu spy to make sure your device is sleeping properly.
It seems to be correct and sleeping right also. Anyway to reset the battery indicator?
If you flash a rom, your battery stats don't get changed and could lead to incorrect readings. If you're rooted, charge your battery to full, boot into clockworkmod recovery, advance, and wipe battery stats, reboot, unplug and let it discharge normally until it's dead before you plug it back in. And keep a lookout for rogue apps that hog resources, of course.
Edit: Lithium ion batteries shouldn't need calibration, due to it having no memory.

My wife's note is the same .........
It even seems that with 4.1.2 it even improved .........
