[Q] Battery issues

Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?

Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.

Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??

Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...

Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_

this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.

Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........

Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?

My battery drains from full to dead in 2 hours

100-0% in 2 hours with the screen off. Superclean 2.8. I've tried "reconditioning" the battery by letting it drain and wiping battery stats, but it doesnt help. What can i do?

try running the battstats script, do a search for it

As a general rule, ONLY flash new roms with a fully charged battery

Have you ever over-charged your battery.?

even with on I still get several several hours of battery life on sc2.8 I get full day charges with wifi on at home, playing music while driving, constant internet searches
Sent from my SCH-I500 using XDA App

I flashed SC2.8 Sunday morning at 1:00. I was at 98% battery, and ran fxpms and battstats right after flashing.
When I woke up at at 7:00 my battery was down almost a quarter (about 76%). I noticed in spareparts the time without sleep was over 5 hours. I turned off GPS, WiFi, and auto-rotate, then turned them back on. Then I ran /system/bin/sensorcalib_yamaha from terminal emulator. It is now almost 24 hours later and I am at about 25% battery.
Since your battery life is so bad, I would also recommend turning your phone off and doing a complete charge on a wall charger (i.e. not a computer). Maybe try the things above after doing that. Good luck.

Just for comparison
Just for comparison: Stock unrooted EA28 gives me over 50 hours of standby on one battery charge. I did not used the phone for calling much, but I have Skype running 24/7 and of course I check email and sending texts. Bluetooth, GPS, Wi-fi, 3GData is constantly on. Now I think that's how it should be. Two days on one battery in standby with minimal use, not 2 hours.

I was not getting horrible battery life but it went down hill when I went to SC 2.8nv from 2.6 which I did with a full data wipe.
Running bstats at 100% (charged until it says 'full' in Spare Parts) then 3 full cycles from 100% to < 5% helped me some. Not life changing but noticeably better battery life. I'm doing one more full cycle right now. Than I'll go back to putting on the charger when I get the chance.
I have charger by my bed, a cord hanging from my computer and one in the car. Not too hard to keep it charged up like that.

No not at all, try going into terminal and enter
Su
Fxpms
On the latest superclean and that should help and wipe battery stats on a full charge, trust me I've had the same problems where I wouldn't use my phone at all during school and at the end of 6 hrs it was dead when I checked...

What I've found so far--
1. I seem to sporadically get a "time without signal" error but that results in standby using significantly more battery than it should. you can check this by looking at phone info. If your time without signal is 50% or higher (and you are in a good signal area) you have this issue.
Workaround: Toggle airplane mode on and then off each time you reboot your phone.
2. GPS radio doesn't always release wakelock. Therefore the phone won't go to sleep and the battery will drain like crazy. You can check this out using Spare Parts.
Workaround: Disable GPS when you aren't using it. Some people have reported that opening Maps and then closing it will also release the wakelock.
3. There seems to be a bug in sensorserver_yamaha which controls the rotate settings. You can check to see if this bug is effecting you by looking at the CPU usage of this process.
Workaround: Disable auto-rotate. OR This may be a fix but I am currently unsure. Boot up terminal. Su to root. type /system/bin/sensorcalibutil_yamaha and run it. Follow the onscreen instructions.
You still might need to go through the battery re-conditioning process. However, as far as I can see, these three items seem to be the biggest culprits in fast battery drain on SC 2.8.

I am confused. Where is this "phone info"?

Use spare parts and see if under battery history, other usage, the phone is at 100% running. If it is, something is preventing the phone from sleeping, and causing your issue. For me, the proximity sensor was creating a wakelock and the phone wasn't sleeping. I Odin'd stock EB01 + 2.2 pit and then reflashed cwm recovery, the rom and kernel, and so far, I haven't had the issue repeat itself and battery life is much improved.

[Q] mikg 1.03 battery issues

This is by far my favorite Rom yet but I'm having battery issues that I haven't had before. I unplugged my phone last night at 100% and when i woke up 5 hours later my battery was at 68% normally it would only drop about 10% or less in 5 hours. any ideas? I have all new radios and wimax and such.

Is your phone sleeping?
Sent from my PC36100 using XDA App

Once we get a new custom kernel, it should remedy the battery issues on that ROM.
We just have to wait for HTC to release the source for the latest kernel.

OK stupid question how do I know if my phone is sleeping ?

At 7am I reset battery stats and put in a 100% battery (charged on an external charger)
Now (11:15) I am at 69% I expect this to get better once the batt stats are done.
I have new radios and the kernel for the ROM.

stock battery. i dont think my phone is sleeping.

If you have mobile data on, your battery will drain a lot faster, especially while we're all stuck with the stock kernel

No battery problems here. Altho it is the stock Kernel, i can easily use my phone for a full day with several calls, a bit of gaming and youtube (3G) while in the pooper and have 50-60% remaining in the evening
Try to reduce app sync frequency (you don't need that when in bed really..), LED notifications
No juice defender, or taskiller, or extended battery- just using setCPU with "onDemand" governor

That's about where mine is, too. I'm used to my SBC setup though, where I'd be at 85% by the end of the day.

You should not be losing that much battery over night. I generally only lose 2-3%. Have you checked your battery usage? Post a screen shot of it.
It looks like this
http://smartphoneblogging.com/wp-co...ngerbread_battery_consumption_app_graphic.png
You can see when your phone is awake vs screen off. And if you click on the apps in the list, it will tell you how long that app kept the phone awake,

So when can we expect a custom kernel. i use set cpu with ondemand also no juice defender or app killers here either.

So something is waking up your device then. You don't have the wake lock issue. Do you use google latitude? That is a huge battery hog

yes i do use latitude all my sync like facebook and weather are set to 1 hour but have always been and never had this problem before.

Try it w/o latitude on. I only drop 1-2 maybe 3% through the night once i turned those off. I have my facebook contacts set to sync once a day (don't really need more than that unless you add friends a lot or they update their picture frequently)
Weather I have set to 3 hours, but there is an option to update on device wake..so that isn't an issue either.
Give it a try and see if it helps.
Also if you haven't calibrated your battery, charge your phone to 100%, boot to recovery and wipe battery stats, drain battery til phone shuts off and then charge phone back to 100%. I can usually get about 24 hours of moderate use out of my phone.

ok will try those. i did battery wipe just yesterday

just click the link in my signature for some really good battery tips

OK guys so nothing I done helped my battery life while sleeping so I wiped wiped and wiped again and reflashed twice set everything back up and now my phone sleeps again. These roms can be funny like that sometimes I guess. Any thoughts on that?
Sent from my PC36100 using XDA Premium App

Roms, especially ones that are ports, can be weird like that sometimes. If a couple of wipes and a re-flash did the trick then I'd say that's great.
If not, then it's just bad luck I guess. Hopefully the kernel source will come out in the next few weeks and we'll be able to get kernels that can squeeze out better battery life.

Terrible atrix battery

I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated

Edit : phone idle consumed 40% :O

I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot

Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...

New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.

Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.

The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same

When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.

How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.

i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.

I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.

When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)

After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.

Battery Drainage

I've been using the Aria for 2 years now, and just 2 days ago I ran into an unexpected battery drainage problem.
1. When I am speaking during a call and not holding the phone close to my ear, the proximity sensor is not always triggered which causes the screen to stay on. While the screen is on, the battery drains 1% every minute (or every 30s). When I turn the screen off, the drainage is fine.
2. When I receive text messages (voicemails from my landline trigger a text message on my Aria), the battery drainage is very bad (1% per minute or 30s).
I never use data networks (turned off), background data and autosync are both turned off, gps is always off, wifi is always off, screen brightness is always custom at the 3rd lowest brightness setting. Basically, I try to conserve battery life and only use the phone for talking.
When I looked at battery usage, it was mostly due to Android System, Voice Calls, and Cell Standby.
I'm running the very old Liberty Froyo Rom (the version released like 2 years ago) and the default CM7 kernel. Also, I upgraded to the newest radio to fix this problem, but it didn't seem to make a difference. I don't think these things should be causing the problems since it only occurred 2 days ago while these things have been constant.
Any ideas what is going on or what I can do to make my phone last longer? Talking on the phone for 30 min from full charge takes my phone down to 25%...

honestly at this point my battery meter is completely wonky. the percents mean nothing now. i still get roughly the same battery life but it'll burn through large chunks of percentage in minutes but sit at a single percent for hours or active use.
i'd say try a new battery

If you've got clockworkmod installed, boot into recovery and wipe battery stats. If you're still experiencing this, try a different rom. I've been using CyanogenMod 7 for a long time with no issues.
If this fails, it's probably your battery. It might just be pooped out. If you get a new one always buy and OEM battery! Don't get anything off-brand.

really? its about the battery? not the OS itself?

after 2 years of use it's safe to assume that it's the battery and no necessarily the rom.

2 years with the same battery? old battery i say and is usually the life expectancy with it. i say you get a new battery. or try charging your battery all the way full. wipe the battery stats. then let your phone die, then completely recharge it all the way up again. that worked for me.

Battery life with ANY Android phone is hit and miss, but the Aria is notoriously terrible with it. However, there are several "tweaks" you could do to help it (note: I said help, not fix.). Beyond the basic system setting adjustments, I have found the "Die Hard Battery Calibrator" script by zeppelinrox to be helpful. Look for his V6 SuperCharger thread here on XDA to find it (as well as other useful scripts). Of course, the usual caveats apply: S-OFF, root, magic powers, etc.
