[UPDATE,FIXED] Battery lowered 10% in 2hrs while on Airplane Mode/ Wifi Off.

I was in a class that is from 7AM-11AM. The classroom has no signal whatsoever so at 7AM I put airplane mode on, didn't turn on Wifi, closed all open tasks and just for the heck of it turned off background data.
When I put all this into effect, I was at 91%. At 9AM I see that my battery went down to 81%. How is this possible? I was in airplane mode so nothing was synching or downloading, no programs were running in the background or anything at all. On my previous phone (Nexus One) under the same situation the battery would have been at 90%.
Phone Idle- 34%
Cell Standby- 30% (Time without signal 85%)
Am I missing something here? Can someone please elaborate why this went down so much for basically doing nothing.

Did you drain your battery completely the first 5 to 10 times charges, when you first got your evo? Many people claim that's how to he the maxium battery performance from your battery on any phone

Normal. I lose about 10% every 2 hours.

Yeah but I wasn't even using it and it was in Airplane mode. That can't be right

WOW... sounds like its your CPU thats still killing the battery??? You don't have it rooted or running any cutoms ROMs on it?
We SERIOUSLY need to get a UV kernel on here and underclock this thing when its asleep... So many battery drain issues.
Your issue is REALLY strange though.. I was in LA yesterday and mine didn't drop that fast for like 2 and a half hours... Very interesting......

This is bogus. Don't bother doing this. That was something that was needed back in 1999 back in the days of NiCad and NiMH batteries... It doesn't help LiIon one bit.

20 hours of battery life is pretty good. I think the record is like 62 with everything completely hacked down. I get about 4-6 in full on usage.

I understand that 20 hours of battery life is good but If I was using the device in those 2 hours I wouldn't be worried. But I wasn't, it was completely IDLE with all the radios turned off and programs killed (advanced task manager).

that is NOT normal lol when my phone is on standby i loose about a percent per hour overnight....

Deactivate any syncs you don't use. Make sure your phone is set to CDMA. See what processes your phone is running that are killing the battery and disable them.
I get about 27 hours on my battery.

I fixed the problem. I rooted 2 days ago (evening) after getting such bad battery life and I flashed Damage Control 3.0.
Today after 2 hours and 30 minutes of being under the same exact conditions as my original post (30 minutes more this time) with Airplane Mode, Wifi Off, Tasks Killed,etc I only lost 1%.
I went from 93% to 92% in 2 hrs/30 minutes which is a hell of a improvement in comparison to losing 10% in less time (2hrs) with the same exact circumstances.
I am extremely happy now. Oh and by the way, yesterday I got 14 hours of usage with this ROM which for me was unheard of before (4-5 hours)

How fast do you drop to 90%?

My battery life has always been pretty sh**ty even b4 all this phone hacking and crazy apps..
Currently it takes me aroune 10 to 15 mins to drop to 90%... but that maybe just a bad batt app reading..
nevertheless I cant go a whole day without charging once or twice...
I carry my charger with me everywhere.
How people get 3 days with this phone is beyond me... Maybe its bcuz I love to use my phone mostly as an ipod.

from 6 am to 2 pm still above 90. (in school, airplane) actually sitting at 67 right now and unplugged at 530 am.

OMG.... Teach me your ways... What are you running? Any Custom rom? Do you like not use many widgets? Or is it simply cuz you barely touched your phone all day?.... lol even i did that just idle sitting it would probably be 1/2 batt in like 4-5 hours

if u mean std widget u should know that it switches to 90 when actual procentage is 9x. So when @ ledefy && motocharge i have 99, there is 90 @ widget.

I get around 7hours wih 100-90%, it drops to 99% as soon as i unplug

Honestly HOW! I cant even imagine that... You guys have some kind of special batteries right?

no special batteries or rom. everything stock. my clock speeds are stock i just undervolt. 300/17,600/31,800/42. might not work for everyone but im not a power user and dont play many games. thats what the game boy is for after all

Me too having the same problem and I am on stock rom and indian firmware and battery sucks and motoversion is 2.59.0 have lots and of games n apps but I have only rooted the phone with superoneclick hope you people can provide a solution for getting a better backup and yes I have even tried calibrating the batter but no use at all still I get the same problem battery draining and drains completely within 9 to 10 hrs even after minimal usage!!!!
Thanx in advance!!!

Same for me. Since Moto only shows 10% changes you have to let it charge a good hour before unplugging when you see it's at 100%. It will show at 100% when the charge gets to 95%, so you could be losing 5% charge right there. I'm using the 1% display app from another thread around here, and I only unplug it when that app shows 101% charge. As soon as I unplug it, it drops to 99%, but lasts from 99% to 90% for about 7 or 8 hours if I don't really play with it. My usual discharge is 1% an hour. The phone/battery is programmed to not overcharge, so even if you leave it charging for 24 hours, as soon as you unplug it, it will drop to 99% instantly.

U mean motocharge app?
It always stops at 100% for me, never goes over
one thing noticed today... uptime was 2days 10hours and something ...and i had 1% battery left on motocharge ...and it took me forever to discharge that last percent
I did full brightness, full volume on music that was playing, turned on wifi and BT and played angry birds meanwhile ...and it took me like 30minutes to burn down that last percent of the battery, so Im guessing it isnt calibrated right

No. This one: http://forum.xda-developers.com/showthread.php?t=930457
Sorry wrong link corrected.

battery life drains out pretty quickly... i'd say it drops below 90% after an hour or so. one example would be 9am-2pm with texting, whatsapp-ing and the occassionally surfing, and i'm down to 30-40% batt life.
i think the major draining app would be those that run data in the background, coz i was in japan recently (data turned off while roaming) and a full day 9am-12am and i was hovering around 70-8x%.

My - Battery Sucks -

I have to charge it twice a day, and my use is for only couple of hours talking and few browsing.
I tried that with stock as well as
[ROM] cwm-Phantom-X-
is anyone else also experiencing the same?

a few hours being like 10 hours straight talking?

You're crazy. This battery is the best I've seen in a long time.

im getting 12 hours with normal use and 8-9hours with very very heavy use(basically on my phone all day non stop)

I can drain a battery in 6 hours or less. I can't make it through a 8 hour work day without charging it. I guess you guys that go 12+ hours on a charge aren't power users. I tried every rom and kernel and my results are exactly the same.

Maybe the people who are complaining about battery life came from a flip phone or a blackberry. As far as smartphones go, this is the best you'll find for the features and enormous screen we have. Don't believe me then get an Amaze, Sensation, myTouch 4g Slide or G2x.

I dont know bout anyone else... but the only battery problems ive experienced is the fact that ive become so damn lazy on keeping the phone charged.
The battery lasts so long that i forget to charge it, and then i run out of battery

I'm a heavy user literally all I do is watch 1080p movies and plays games on my phone. I get twelve to fourteen hours every day. I also get at least a text every fifteen minutes if not more. Maybe the developers didn't remove career ciq which bogs down performance and drain the battery. You can also try a different kernel.

don't forget that in areas where you have crappy signal, you phone pumps up the power to try and compensate. you may notice your phone heating up in your pocket too. If you have no signal at all, i weep for your battery life.
go into airplane mode to save juice.

I too get 24 hours or more from light to moderate use with juggernaut.
Heavy use still nets me at least 10 hours. Although I toggle things off if I remember and don't need them. Like wifi, data, auto bright, sync, etc. although WAY lead important with this phone than it was with vibrant running cm7.

Why don't you try adding another core to your G2 and see if you can even get 6+ hours!!!
Cmon man, this is a dual core phone...it's just common sense that it will use twice as much battery power to get it to run smoothly.
But honestly, I was able to get 21hrs out of a full charge. With heavy use but i had it UC'd @ 1.2max and 192min. Still ran pretty smooth tho.

I get about 18 to 20 hours from a full charge. Stock. Non-rooted, and no modifications of any kind. I have all my apps auto-sync every 4 hours, and my usual display "on time" is around 4 to 5 hours. Here are some screen shots. This is the best battery life I ever had.

Just to add. My brightness is at 40%

is it better to use autobrightness on our device or a set brightness setting to save battery?

I'd say set it to certain level. Having the phone constantly adjust I would think would use more battery.

Best rom for battery? Current rom burns 1% per minute.

Currently using latest calk rom I get about 2 hours using my phone for browsing thr internet at home. When 3g is turned on it drains even faster.
It has always been like this. If the phone is set on idle without 3g and wifi it lasts about 10 hours.
also it takes about 3 to 4 hours to fully charge, i feel this is too long.
so any rom that might help me? is the battery faulty?

Blazer ROM

why are you using your phone to browse all day long ? use a pc or a tablet. its a phone not a desktop pc. plus put it into airplane mode and then turn wifi on, it disables the cel/data radios hence the battery last longer. If your phone takes 3-4 hours to charge from 0-100 something is wrong with it. turn if off and charge it, cuts down charging time A LOT !

That is ridiculous. But I've been using Blazer Rom for about 2 weeks now and I always get 30 hours+ battery life. I just got 3.8 and I hit over 40 hours just this weekend.

well, um, wow, those are some ... great suggestions...
you might have a bad batt, sure.
i would think it is likely something else though.
a few things off the top of my head.
is this on a "clean install"?
is there some app you have loaded that might be pinging/updating constantly? (I'm on the exact same rom, getting all day at least)
what modem are you on?
did you flash a custom kernel?
do you know how to take a screenshot of battery usage? show us what processes are eating it?

It could be a bad ROM (bad install, not the ROM itself), but don't presume that's the case.
Measuring whether the phone is draining appropriately is difficult to do when it's in active use (e.g., 2 hours of browsing) ; thus most people measure effective drain by measuring the drain rate when the phone is 'sleeping' -- though in some cases a bad app or bad install will prevent the phone from sleeping.
I would recommend charging the phone to full, leave all default radios on (GPS/Wifi/3g), and let it sit for an hour or two. If you're losing more than ~3-5%/hour, then you have a problem.
Tools you can use:
- CPU Spy - Will show you whether your phone is entering Sleep state or not
- Battery Monitor Widget Pro - will measure your mA drain rate; during sleep, you'd want it to be at least below 20mA, ideally below 10mA (note, this app requires a couple of charge/discharge cycles before its measurements are reliable).
- Better Battery Stats -- If you find your device is NOT sleeping, this will help you figure out what applications (including the kernel) may be preventing the device from sleeping.

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.

how long has it been since you flashed? Maybe it needs a few cycles to settle. Do you have any wake lock issues? get betterbatterystats app, free for xda members, to check for kernel or partial wake locks.
I'm on BlazerROM 3.7 and getting about 1% every 2 hours on idle. It took me a week to see the battery life i'm getting now. My wife is on calks 2.8.1, I don't know what shes getting but when she gets home from work, she's still around 50%. On stock, she was typically around 30% already.

how do you get betterbatterystats for free as an xda member?

I'm on blazers and i'm at 79% battery at the 7hr mark on battery.

I have seen this "mystery battery drain" problem in other threads. There is usually an app responsible. Try Watchdog, its not bad.
I also have heard that SD card or file errors can be responsible for the drain. Formatting the memory takes care of the problem. If it were me, I would format the memory, then run chkdsk (Windoze, or the equivalent in another OS) to mark bad sectors. In the case of internal memory, you will have to do that through the USB cable. Do so at your own risk, of course

The point is you walk into someones situation and act as if their usage of the device on whatever rom your on is going to produce a parallel experience. One of the biggest factors no matter the rom is screen brightness. If you spend most of your time out doors the experience is completely different even with the same usage patterns otherwise. I love screen brightness personally, haptic feedback is nice too who cares about the battery when the experience is better?
I have games on the phone, GTA III, MC2/3, Dead Space, etc. I don't actually play them. I remote into my PC, browser the web. I have a TON of apps that use the phone idle/background. I keep steam and im+ pro going. I let TEP ping GPS data every 10 minutes. Weather widget, google voice, etc. I even have Samsung Apps installed with its oh so horrible push service that apparently rapes peoples batteries... cant say it hurts at all.
Today was a day for me where my boss was around so I couldn't use the device much and when i did it meant leaving things like a remote client on because I couldn't touch it to turn it off. 52% battery was left after 12 hours so it obviously was going to survive the 16 hours I am awake, going to sleep now so it would easily last 24 hours. But the battery being Li-Ion and me actually caring about it, its going on the charger. Tomorrow could be 30 and the next day will probably be 8 hours.
As far as the topic is progressing. Check your apps and your settings. Ive had battery life so bad the phone died on the charger. Same rom, same apps slightly different setup later and I am getting good to acceptable and that constant wake this guy is probably getting is gone.

If your using a lot of push apps, you're battery becomes nothing more than a decoration, lol. Apps like aim, kik, basically all the chat ones. Games like words with friends. The more apps you have checking for updates on top of heavy usage with kill your battery fairly efficiently

Which personally was part of the issue before on my setup. I still have them going again and battery life is decent. I mean Id want 16 hours out of a phone surely whatever my day is Ill have it on a charger by bed time.
I personally usually get 12 hours or more on days Im not using it constantly, 6 to 8 if I am using it every waking second. 24+ on days off. Haven't tried blazer in particular myself yet but Calks seems manageable even for demanding use.

How are people getting such great battery life on the Epic Touch!?

I am watching this thread (http://forum.xda-developers.com/showthread.php?p=23272848) in amazement, as people report 24+ hours of battery life, with screen-on time of four, five, or even SEVEN hours!
I can't understand how folks get such great life.
Mine averages about two or three hours of screen time and about 14-18 hours, I'd say. I'm using Blazer 4.0, FB27 modem, and Rogue 1.4 kernel.
I know everybody's usage is different, and also we're all going to get different results due to other factors (signal strength, apps, etc), but I can't understand why the massive difference in battery life!
And I do have an 1800 maH battery.
Note: I do have a handful of apps, but not a whole lot, and I don't think any are destroying the battery. According to BetterBatteryStats, it doesn't look like the phone is having any trouble sleeping. That is, the screen-on time is just slightly lower than the awake time, meaning that the phone is typically sleeping when the screen is off.

With your usage, you feel 14-18 hours of battery is bad??? Id say a day of 16 hours consistently is pretty darn good. Now, I know that I have gotten over a day on battery by using it all day and then forgetting to charge it over night. Sleeping while the phone isnt awake can give some pretty outrageous looking battery life. Again, Id say if you are getting 14-18 hours on one charge, you are doing pretty darn good.

Im lucky if I can get 7-8 with all the "videos" I watch during the day

Well, I understand that when the phone is sleeping, it generally uses very little power -- especially on wifi.
It's mainly the screen-on time that amazes me. How can somebody get seven hours of screen-on time?? Just seems unreal!

Well I am assuming that their 7 hours of screen on time was doing something minor. Then again, these are electronics, and they are all different. He just may have found his perfect set up. But again, if you can get through your day, doing everything you needed to with your phone and lasted 14-18 hours, I would be happy.

disabling fb/twitter sync has helped my bat life improve.
always turning screen off when done rather than letting 1min timer take care of that whenever possible.
wifi is better on battery than 4g/3g. also disable wifi sleep.
other than that.. all comes down to extra 3rd party apps you have and personal usage.

I've never calculated mine all out, but I do get some pretty decent battery life.

Its all about how you use the phone. everyone seems to have there own definition of what "heavy" and "light" usage is but the fact is people getting 14+ hours aren't using there phone all that often. if you want to know how much actual usage time you can get out of the phone check the time the phone has been awake or the time the screen has been on.
for example my g2x goes for about 2 and a half hours of screen on time. my vibrant, 2 hours. havent had the e4gt long enough to see. these numbers of course changes depending on what you're actually doing (data intensive tasks will obviously cause faster drain) but it will give you an idea of how much you can actually use the phone before it dies. if all youre doing is texting here and there and checking email plus maybe 15-20 minutes of games or videos it isnt hard to get through a 10-12 hour day on a single charge. but if youre like me where i spend extended periods of time browsing the net while messaging and texting then the batter is going to die fast regardless of what battery saving tricks people suggest.

I recently removed OfficeSuite Pro 5 and noticed about 15-20% better battery life.
I also removed it from my other android devices and my tablets. Still testing them to see if theres a difference or not but so far it seems a bit better battery life.

I don't know. Just how much can you believe people who are posting on forums that they are not exaggerating? Take for instance the post below where this guy was claiming he got 11 hours of screen on time and STILL had over 50% battery left on stock battery. By far the biggest claim in battery life I have ever seen. And he was insistent on it:

All I'm saying is take what people are saying about amazing battery life with a grain of salt.
I average about 3 hours screen on time, and occasionally get over 4 hours with ~24 hours total time. But if my signal isn't the greatest, like when I'm at work, I get probably 1.5 hours screen on time and 17 hours total time.

I'm currently at 14h 41m with display on for 2h 36m and still have 47% battery left (I'm on stock rooted EL29).
