With very light usage, I've managed to get my Evo3D to last just shy of 2 and a half days. When actually using it, it's been a bit hit or miss, some days it tanks pretty fast, other days it's done quite well. But one thing I have noticed is that sometimes, especially around the 35% range, it'll spontaneously drop 10-15% (it actually did 43% straight to 14% this afternoon). It's visible in the battery use graph as a sudden nearly vertical line. It's never happened when I had the screen on actually doing something, it just happens randomly after turning the display off. Has anyone else seen this? It's pretty confusing.
First thing is first....
Did you download spareparts and see what is consuming battery? In other words, check for a wake lock.
You have to give the battery time to get conditioned. It gets better the more you go through charging cycles. I'm at 75% after 8 hours of moderate usage and that's pretty consistent for me.

For the first week or 2, the phone has a hard time understanding how full the battery is. Try draining it down to 50% or so, and then resetting it. You'll probably see a sudden drop or rise in the battery%. Resetting it will force the issue, but it can also happen while the phone is on. That's pretty normal till the the phone "Learns" the battery.
It doesn't mean you suddenly used 15% of your battery, it would probably explode if you did that... it just means the phone re-calculated the battery's life and changed the number.
Your not alone as soon as mine hits 35 percent ill shut the screen off and here it beep at me and bang its at 14%. lol same as you.
Don't know if it will help you.
I had a similar issue as you, battery would get to around 30ish % I could turn the screen on check an email, set it down and bam 14%, and the low charge noise.
I wasn't trying to fix it, instead I was doing this http://forum.xda-developers.com/showthread.php?t=1153371
When I attempted this I had about 35ish percent battery left, following the directions my phone restarted when it came back up I got a 1% battery warning, then my phone went into emergency shut down. I thought something happened and I was going to have to return the phone. I powered it back up and it read 33%, from there on out my phone now drops a % at a time, and my battery life is as good as the other people who get phenomenal battery. I'm going on 48hours with light usage and still have 25% left. I've txt'd music, videos, nothing heavy.
Take it for what it's worth, I don't know what happened maybe the data reset, resets the battery calibration, I have no clue, all I know is what happened to my phone and the result.

Ever since I rooted my fiances and my phone his battery life is so much better then mine.
Mine right now is at 92% and has 17hrs 30mins
His is at 88% and has 24hrs 48mins.
Is there any way that I can improve mine without having to buy a new battery?
We are both using kaos v39.
Thank you for any help.

Have you tried calibrating the battery?

The battery % also isn't necessary accurate.
The phone uses a calculation of voltage (as closely as it can), temperature, and activity, to determine the %. Largely, the figure is just based on voltage.
Sometimes, when your phone is charging, it can say 83%, but be at a solid 4200mV (4.2 volts). It's probably not going to charge any further. If you power the phone off, the light will probably turn green (showing you that it's charged). Then if you boot it back up, the battery % might read 100%.
Is it 83%? Is it 100%? Clearly, in the 2 minutes it took you to turn your phone off and on, it didn't gain 17% battery.
The difference between 88% and 92% could be temperature, voltage of the particular battery at the moment, who just used their phone more in the past 2 minutes before checking, and (due to all the variables) practically 'dumb luck'.
What you really will see is if you let them go for a very very long time (until they get to 0% and auto-shut off), you'll find that whoever had their screen on more often (maybe whoever does more texting), or whoever has more 3g internet doing things in the background (if one of you has an email app that checks email every 10+ minutes, keeping the phone awake, and moving data), or whoever works in a workplace with worse reception (that will eat battery very quickly, as the phone uses battery to get 'louder' so that the cell phone tower can 'see' it), will have their phone hit 0% more quickly.
The difference between 88% and 92% may actually be nothing. It's just your phone's 'guess' at how much battery is left. His phone's 'guess' is different, because the variables going into the calculation are totally different for a handful of minor reasons.
I wouldn't sweat it.
If yours hits 10% when his is still at 40 or 50%, with similar usage, yeah, that's something to pay attention to.
But the battery % isn't THAT accurate, to even sweat 4%.
I promise.

Alot of widgets can also change your battery life as well. Especially things like Facebook, location based weather, latitude, etc. Ones that are always updating and using data or gps.

Thank you that makes me feel a lot better. I was starting to think something was wrong with my phone but your explanation tells me that nothing is wrong. =) Thank you for taking the time and patience to explain it to me. I didnt realize how little it could take to eat the battery down.
I recently exchanged a new 3vo after having some dust issues under the screen. This new one is pretty good with keeping dust out but there is a problem with draining the battery even when it's a sleep.
It's been off the charger for about 3 hours after hitting 100% and it's down to 92% after sending a few texts and sleeping throughout most of the 3 hours.
I'm getting worried there's something draining the battery, or if the unit itself is having issues going into sleep mode.

Did you check your uptime/awake time? I usually get 18+ hours of light to moderate use of my phone, I mean, there isnt much to do with the phone because I cant flash stuff yet. I have had two instances, which were odd. I put the phone on nightstand at 100% and after 6 hours my phone completely drained and shut down. Had this happen twice. Cant reproduce it, but I'm sure it'll happen again.
Yeah I checked my awake time and then let it sleep for about a minute. It took about 20-30 seconds to fully stop the awake time after the minute passed. There was an instance where it seemed to not sleep at all.
I don't know if it's supposed to do that.
Hi XDA,
Ive been getting alotta help from you, great developers, and had this question
that dont think has been solved yet. (I searched for 2 days)
So my current situation is;
Im running the latest energy rom (sense 3.0) with stock kernel, (as it was recommended on the post).
After flashing custom roms, beats audio and etc via ADB, i believe my
battery stat display is not normal.
It would take at least 90~120minutes to reach 100% from 99%.
And sometimes even if I have the charger hooked up to the phone
it would still drop to 99% from 100.
I have two batteries (Stock and Anker) and tested them both.
It looks like no matter how long i charge it, as long as i have 100% or 99%
on the battery, it takes around 12minutes and 13seconds screen-on time to drain 10% of the battery. Which it was way less than i expected.
but after dropping around 68~63%, the battery seems to last longer on each
percent points.
On top of that, I think my phone is not charging anymore when I turn to power off. I can feel the phones gone cold and not charging, but the orange light is always on and never turns green for some reason.
So my question is:
IS THERE ANY SOLUTION (LIKE BATTERY CALIBRATION THAT ACTUALLY WORKS?) TO THIS? IVE READ SO MANY THREADS ABOUT THIS BUT NOTHING IS GIVING ANYBODY A CLEAR ANSWER.
I have the same problem as you. I'm on Sense 3.5 RC1.6. Infact I just restarted my amaze in hboot mode and then back into normal. My battery went from 10% to 60%. Then after like 15 minutes of usage it went back down to 10%. Also my battery drains to almost dead at about ~3 hours of screen time with moderate-heavy usage.
have you guys fully charged it ? gone into advanced in Clockworkmod and deleted battery stats?
i havent hacked my amaze but when i had my g2x after every flash i would charge teh battery to 100% then wipe battery stats x2 and then let the battery drain to 0 percent. then it should give you accurate readings
I did that but I used Battery Calibrator app from market. 2 times and discharge to 100%. Also how long should the battery last on average?
I'm runnign stock, it lasts me a day, but depends on usage. I text alot, some calls, twitter facebook, a lot of music, some FML, and some camera lasts me all day, (i charge in the morning so it lasts me a full 24 hour cycle)
Hmm seems as if my battery drains pretty fast. I timed it with medium-low brightness just leaving the screen on, with 3g and music. I get 1% per 3 minutes on. No auto-sync or background data either.
as most of people usually say i should fully drain my battery and charge til 100%,
im doing that right now.
My phone got shut off during my jelly defense stage 13 session
and plugged the phone but it didnt turn on for like 10 minutes.
so i kinda freaked out that the clockworkmod recovery that i have right now
does not support charging when the phone is not awake, but i guess the charging is really slow since i have finally turned on my phone.
im just gonna let it sit on my side table charging, and ill prolly fall asleep..
cuz im definitely not in the mood to watch LeBron James' face tonight.
I will let you guys know.
Thanks.

i hear you.
but after searching several threads about HTC AMAZE's bad battery life,
im slowly being convinced that 3 hours of screen time doesnt sound really that
bad. lol
mine just died around 2 hrs 45 min screen time while the phone was up without a charge for 14 hours. well i guess if i start using the phone nonstop after a full charge, then maybe ill get 3 hours or more.... but still...its only 3 hours...

Once it`s charged make sure you flash 5.5.0.4 recovery. Using the toolkit makes that easy.

thanks. will do right away.
ive overheard from someone that 5.5.0.4 is causing bootloops when flashing
other roms, but did you have any problem with this?
hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。
So got my S3 yesterday, installed some apps, etc. Throughout the day, battery life seemed respectable. Last night, I charged to 100% and let it sit overnight with nothing running. I woke up 7 hours later agreed and my battery was unfortunately at 81%.
1) The first problem (and this may be related to the battery standby usage) is that it claims I had No Signal and No Data Connection which was untrue.
2) The second problem is this "wlan_rx_wake" and "sec-batter-monitor" kept the phone awake.
Any ideas?
First impression for me is that this isn't an issue. I have sync off and update only when charging. Went to bed @95%, woke up it was 92%.
I did notice that it seemed to take a bit longer (than the One S)to get up to it's first full charge yesterday. This might have been my imagination though. It is a fairly large capacity battery.
From my experiences with new devices and even flashing new roms and updates. Give it a few days to cache and cycle. Then once the battery gets broke in you should be able to share your charging / discharging experience. I would rule it out as a hog yet.
This happened with my most recent firmware upgrade on my Asus transformer prime..Updated, drank juice, now after a week its better than ever.
Plus with everything you have on Bluetooth and such that can REALLY drain a phone..
I agree with discharge cycles and OS calibration but there shouldn't be wakelockers engaged.
Turned off WiFi, now there is a "deleted_wake_locks" under kernel wakelocks. What is that? Lost like 4% in 90 minutes of no use and "deleted_wake_locks" engaged the phone for 80+ minutes.
Does anybody know how long the notification light keeps blinking after getting a notification? I woke up in the morning and the light was blinking and had a text message from about 4 hours before the time I saw it. The blue LED was blinking. I hope it doesn't stay on until I see the notification since it's gotta use some of the battery.

That's pretty much the point of the LED - if it only lit up on arrival you'd have to be staring at the phone all of the time. But a flashing led like that should have a tiny impact on battery life.
there is a thread or two in the I9300 forum about cell standby, wireless wakelocks and battery drains. i was hoping i wouldn't hear about this with the US version but it looks like something similar is happening.
http://forum.xda-developers.com/showthread.php?t=1698289
You have one bar in the picture.. is that the same place you left your phone overnight? Even if you have signal albeit low signal your phone gives the radio more power in an attempt to hold onto that signal. That could have something to do with it. Also, I guess wifI is holding a wakelock :/

i have to agree, low/no signal sucks bat life big time!
looks like wifi and bluetooth wer in use the entire time....
another tip, when you get done charging it, reboot it.
me personaly, i charge my phone while im asleep, then unplug and reboot as im headed out the door in the am...
to me it seems smarter to start the day with a full tank than a partial one and wind up hunting for power later....
i have no complaints about battery life..i have been on the same charge for 15 hours with light phone calls, heavy texting and web surfing, and my battery is still at 36% and this is only after my first charge cycle so i am guessing it will only get better after a few more cycles
After a few days with my SIII, I can say that the battery life is not quite as good as the One S I had briefly. It is however way better than the G2x, Evo, Indulge, and Sensation.
I will be getting at least one spare battery. I did not like having a captive battery in the one S. Keeping and using spares is not an issue for me.
First charge not bad
