i just got my 3500 battery for my evo i charged it over night but when im using it today it seem like im using my stock bettery 4 hrs already down to 68 percent. i didnt talk much and i didnt surf much watch little bit of youtube.
so many variables, kernels and all that. try calibrating, full charge and resetting batt stats if you didn't already.

I am having the same issue, and from what I have been told, you MIGHT need an external battery charger to get the battery to FULLY charge. Something with the Evo stops the extended batteries from fully charging to their capacity.
There are many of us who believe that the algorithm used to determine battery charge capacity is flawed. When the 3500 mah battery is truly filled to capacity, battery life is amazing. I go through a routine to get my Seido 3500 to completely charge. Place the battery monitor widget on your main homescreen (it is free to download from the market) I charge it until the LED turns green or until the battery monitor widget alerts me audibly. Yes, it can be set to emit an audible alert when the battery reaches 100%. Afterwards, I unplug and wait 60 seconds. If after 60 seconds the battery monitor widget displays less than 100%, I resume charging. I repeat that process until after 60 seconds the widget still displays 100%. Once that happens, I can easily get over 24 hours of use from my battery. My routine is somewhat tedious, but it is effective. Like others have stated, a dedicated charger for the Seido may work better. Anyway, I use this same routine with the stock battery. I hope I was helpful to you.

I think I will give your method a try and see if that will work for me. I get approx. 5-6hrs on what shows a full charge on my 3500ma battery at this point.
I charge my battery til light is green, then leave it on for ~2 hrs. Look at the waveform on bmw. You'll notice after the charge level reaches 100%, the mA waveform looks like a saw tooth waveform. Initially it will be a high frequency pattern, then it will begin to slow down... Once it reaches this slow down state, that's when I consider my phone charged.
Here's a visual of what I was referring to above. The phone's on the charger the whole time, unused (idling), screen off.
mA on top, % on bottom.

Same graph, mA on top, mV on bottom
to add another method to the mix it's similar, not trying to knock on any of the others mentioned at all
I found that the most accurate way to utilize the BMW for a full charge is reading the mA's..
..after either placing widget on home screen or activating >menu>settings>monitoring preferences>monitor without widget>history update rate>60sec..
..then after light turns green check mA's in history it will be positive mA until it goes from triple digits to double then single when it reaches zero its at capacity/full then it will stop charging and start to go into negative mA. unless its a sbc kernel it should keep bumping a single digit mA if nothing is keeping it awake..
..unplug at zero and it will stay at 100% for a long time on a extended battery. best I got was 10 hours (at100%) with minimal use and 5 with moderate on a 2400mAH.

I, too, watch the mA using the battery monitor widget (bmw) and many of us used to charge the battery and wait until the mA dropped to 0. The problem is that many of us could never get to 0 or by the time it got to 0 the phone had been charging for about 8 hours...of course I'm being overly dramatic here...lol...The point is this: when the phone's LED initially illuminates indicating a full charge, chances are it is not full and you will have to employ some additional charging methods to truly get a completely charged battery. Several methods have been offered here. Pick one or try them all and then decide which one is acceptable to your tastes and patience level. Take care.

@madflasher, your battery history log is indicative of a SBC kernel. Is that what you are using?
A non sbc kernel has a bump type strategy, while sbc is trickle.

Hello forum and its inhabitats ! I have a new issue today (a new thread about it at least, the issue was here always); battery capacity and the SGS2 battery life ! My GS2 was sent with a 1650 chinise battery -- im not very happy with it. Using the phone quite passively leaves it with only 6 hours of battery life - i checked and it was roughly 20% per hour -.-
So i was browsing ebay and stubled on battery replacers for the GS2, one of them being a 2430 mAh capacity battery (http://item.mobileweb.ebay.de/viewitem?itemId=130594902895&index=14&nav=SEARCH&nid=15065655277).
So i wanted to ask, is it a fake ? Which battery should i buy to prolong my phone's life ? Thankyou for anwsers by time ^^

Oh and what i want is an extended battery without having to get a bigget case or anything. And, should i buy a 1650 again, just the japanese version ? Come on people i know you can anwser this
Sent from my GT-I9100 using XDA App
The Anker 1900mah battery (amazon.co.uk links: single battery, two batteries + charger) is probably the best extended battery which is the same size as stock (no bigger battery cover needed)
20% battery per hour is not normal with whatever "passive use" means. I would first investigate what's using up your juice before getting a new battery. Go into Settings -> About phone -> Battery use to see what's going on. Your phone might not be getting into deep sleep in which case BetterBatteryStats from the market might help you.

Yes its fake, only buy original samsung batteries, samsung has a larger 2000mah battery if you want more capacity.

Yeah, the screen usually eats 65% of the total battery. Where and what should i search in this betterbatterystats ? (downloaded it already).
And yeah, not quite passive use i'd say ^^
Sent from my GT-I9100 using XDA App
Well, if the device loses 20% per hour, its probably not going to sleep.
When looking at the battery stats (settings > about > battery), try to see if the device is awake a whole lot more than the screen is on.
If it does, with betterbatterystats you'll be able to see by going to "Partial wakelocks", whats the cause of it. if an app has a long wakelock time it is probably the issue for the battery troubles.
try to see if you have facebook sync, maybe its causing it as well.

Im gonna run System Monitor today, to watch what apps used what and how much. Plus BetterBatteryStats at the end of the day. Lets see whats wrong with this phone <.<
Im also using Revolution ROM (2.7.1 i think..) with the CF-Root kernel. What i turned on by myself is: screen brightness minimum, sync of Gmail and Twitter (quite often, twitter every 5 minutes and Gmail i dont know how much. Constantly i think). Gtalk is always on, Mobile data is always on too, i do some browsing at times and some games too (at a higher screen brightness usually). AVG antivirus is always on, Latency is updating my position, Evernote large widget (the only widget im using, everything else is shortcuts). And thats it.
I know it may seem much but i still think it shouldnt be eating THAT much. Especially when its screen is off for 4-5-6 hours per day because of school.
Im also gonna post the apps that shouldnt be running in the background this evening (im from germany)

Eh.. I think i'll do the run tomorrow and post tomorrow's stats. Today my phone crashed once, and i turned it off once aswell, so i have a 30% gap in all monitors (from 70% to 40%) soo yeah.. Post your suggestions, people.
I'll test out this battery, and then fix some issues and test again, then do the same to the 1900 one higher in this thread to see the differences

Today's results:
-unplugged this morning at 7:33 - 100%
-plugged in right now at 16:23 -5%
So roughly my battery lives ~9 hours per day. Why im still not happy ? Because im not using it the half of the day due to school, and when i do use it, the discharging is a bit overwhelming in my opinion.
Turns out it drains 11%/h or so.
I'll post the numerous screens from different applications, hoping that peoplr will help me improve the battery (since i know a lot of other people have their phone living for 20 hours !)
Also, you will notice the skip in the stock battery monitor and in the system panel app, its just how i said in my other thread - data loss. I was reinstalling chainfire so that the tegra game would work, and ofcourse the phone rebooted forcefully after installing/upgrading the CF3D plugin.

Odd: Those two Bluetooth services
None of the next ones should be running in the background in my opinion:
None of those eighter:
These too shouldnt be here ?
Samsung keypad i understand, but i didnt knew it always runs in the background. Others i dunno.
WTF Skype, i haven't opened you in weeks !
Those that are EX here i know they should be working.
XDA runs in the backgroud ? With otifications i guess yes, but i had none untill now and will turn it off. Also, system apps begin, and i wont comment on them
Except for this one maybe. I have my Latency location updating, so that explains the friends location

Sorry guys for the overload of screenshots.

UPDATE: today my screen (when it was used) was at 20% brightness, and i deleted the twitter account, so no sync every 5 minutes (i still dunno about GMail, maybe its constant ?)
Also ! I dont think my screen really used just 48%, its usually more - around 60% ! And today i actually saw that it was 73% at some point but then it would fall down to 60 again due to idling (probably the data was lost. Again.)

if you are looking for a new battery, the anker 1900mah is the best you can get without increasing the size of the phone! It is also the only third party battery that is proven to be the mah they claim it has, some even get 2000mah with this battery.
If i was you, i would first disable all your widgets, and then check again! If its a big difference, add them one by one slowely! Some widgets can cause battery drain. If that doesnt help you can try to reset your whole phone back to how you got it in the beginning and then slowely add your apps back.

So today, with pretty heavy usage (at work...checking facebook, twitter, email, web, texting, maybe 15 mins of youtube) I ran through all 100% of my Samsung 2100mah battery from 7:30am until 1:30pm. And I put my 100% fully charged third-party 2200mah battery in right after and now it's at 40% by now.
Unbelievably how terrible the battery life is with the S3.
This is with wifi turned off. with GPS and bluetooth turned off. with not a ton of apps running in the background.
So 1.6 fully charged batteries in 10 hours of occasional use. Wow.
The battery life is like 95% the only reason why I miss my iPhone.
ps. yes I've done the fully charging and fully discharging thing with these batteries.
That's either a bad device or something rogue is running. You are one of the few with that bad of battery.

Either way. 160% battery life cycle in 10 hours of sort of heavy usage is nuts.
In the morning I'll be just reading news on Flipboard and Pulse with brightness at like 60% and running wifi, no GPS running, with no huge apps in the background and it can go from 100% to 90% in like 30 minutes of reading news.
Could be a bad device or maybe some garbage running in the background. I get 14+ hours of average use out of my device.

Seeing posts like this make me want to order that battery. Probably will this weekend.
Okay, I know comparing battery stats is almost pointless but I will finally share my experience.
I am a copier technician. I work roughly 8-10hr days. I am literally constantly on my phone. Why? Because I use OTG USB A LOT. My usb flash drive is connected to my phone from the time I get to my first service call, to the time I get in my truck to drive home. I use OTG because I have to use different service manuals through out the day. So I am constantly accessing my flash drive for at least 45 minutes, each hour, every hour until my day is done. By the time I get home, I am down to about 30% or so, give or take 5% maybe. I use it at home to browse XDA until it just about dies. Charge it all night, than do it all again the next day. By the way, on my way to and from work, I play music in my truck. So roughly I get 10-14hrs out of my stock battery.
I have 58 apps installed. And Adobe Reader and sometimes that stock PDF doc viewer bloat is constantly running because my service manuals are pdf.
IDK.... There are so many threads/posts about battery life. I enjoy my Smartphone to the fullest. Run a ton of apps and and many widgets.
I used to try to do EVERYTHING to increase battery life, task managers, Better Battery Stats, going thru cycles of discharging and charging, wiping batt stats, calibrating battery, (which I still do). Underclocking, messing with voltages, etc etc etc.
It got to the point where I was so concerned about battery life I was missing all the great features of these phones.
I use my phone and all its features to the full potential. I bought a cpl batteries I keep charged around me incase I need them. And Overclock and just enjoy my phone.
Watching my battery life constantly and doing everything thing I can to increase it just took the fun out of of having a Smartphone with all these features.

What I've noticed on my att GS3 is that the battery destroyer without a shadow of a doubt is the LTE/HSPA+ radio. With this on battery drains at least 10% per hour especially with the LH9 update. As a test I shut off only mobile data toggle and the amazing battery life I had with my iPhone 4 returned on a more advanced phone. However, that came at the cost of having to shut off the mobile data connection. Mobile data toggle off all day at work 8+ hours and when I got home battery was like 85%.
I believe the data radio is the culprit and I hope they learn how to optimize its battery usage.
Had the same issue with the stock battery I had for 2 months, where just playing music screen off with about 15 minutes of data drained ~40% of my battery in about 2 hrs. Decided to get a replacment, with the same usage I still had 86% after 2 hours. Battery drop has also gotten worse with LTE on the LH1 update

I'd say you've got a bad battery, or a bad phone, or your ROM is bonked - there's no way you're burning through that much juice with normal operation. Maybe talk to your provider and see if you can swap the handset?
Oh, and discharging/charging your batteries does absolutely nothing. Li+ batteries have no memory, so you don't need to drain them - just use them out of the box and they'll work fine.
Might be a bad device or some garbage may run in the background, my cheap Lvbattery the Extended Battery For the Samsung Galaxy S3 [4500mAh the extend the battery] purchase. Eiemall.com fantastic. Easily over a full day
flashed a different ROM than C9/C10, "Triune 2" and started using the excellent battery/setting tweaks in "Go Power Master" and have noticed a pretty decent improvement.
Mainly by having Power Master turn off wifi/gps/location services while the screen is off, and only having my music/messaging apps running and shutting the rest off.
Highly recommend that app.

looks like its about $25 on amazon
but its thicker than the normal battery, so you get a extended back cover with it. sounds awesome but if you (wisely) use a case with your GS3, you'd have to find a different case

Actually This is what I was referring to, when using the phone the battery drains nice and slow. better than I would expect to drain during screen on time. But when I take it off charger at 6 am and leave it in place and come back at 11 or 12 am I lose about 10% which shouldn't be normal imo. See below:

looks to me that ur messaging app is going crazy...everything else looks normal.
what can I do to fix this? Its annoying. And no this shouldn't be normal, I like everything about the stock rom and wouldn't like to root just for the hell of it. But this actually has me thinking, (still leaning towards no as I still get thru the day) but would like to get if fixed non the less.
I noticed the same thing. When i unplug it in the morning it drains faster. But when im waiting for the fully charged notification to pop up then unplug it lasts longer. Its strange, maybe has something to do with charger. Do they have "safe mode" after fully charged to prevent overcharging or something?

I always wait for the battery fully charged unplug charger notification to pop up before unplugging. So that doesn't seem to be the problem.
Faster drain is normal from 100% to 90%. It was explained to me that when you leave the phone on the charger overnight it charges to 100% and then allows it to drain some, then starts recharging again. You may really be at 95% when you pull it off the charger despite what the phone is showing.
First, get Better Battery Stats. It can help you figure out whether something is eating your battery abnormally.
Play store link
Also, I highly recommend GSam Battery Monitor It might be a little easier to understand than BBS, but I like and use both.
Finally, read this: Your battery gauge is lying to you!

already on that setting also today I left the phone in my car for a few hours (after sunset) and when I came back the phone drained from ~50% to 0% and was very hot.

both apps are working without rooting.
BBS should be the best app to find out which process is your problem.
This phone gets hot randomly, guess it was just humid in your car. I feel like all this battery talk is useless android has never been good with battery life. This phone is huge and powerful so battery drain is going to happen. Also depends how long you had battery, how much you over charge battery. I read in several places that after 3 to 5 months of use batteries tend to drain faster.
Your best bet if it's such a big issue is getting another battery with a separate charger. Honestly in this day and age these smartphones should come with an extra battery lol

My battery and phone are both less than a month old, as for humidity that doesn't drain a battery from 50-0% on idle in a few hours. Also I've posted new screenies, messaging used ~20% without being used and stats showing 0s awake. maps did something similar despite disabling all location services and unticking all boxes in the gps submenu. My issue isn't bad battery life, its idle battery life. I shouldn't lose 2% per hour or more when I unplug and go back to sleep.
I have always felt that stock has offered the best battery life in both standby and active. I re installed 100% stock rooted with this method (thanks reddevil) http://forum.xda-developers.com/showthread.php?t=2052321. I also installed the LG Optimus fast dormancy tool that I found on another XDA forum and can be downloaded here: https://drive.google.com/fe/m?gsessionid=WZD8FPkXXWpJWcFV3xyoCg# and this is what I acheived:

Stock... Sweet huh? I found that by disabling fast dormancy it makes a huge difference in standby battery drain. Unfortunately it only works on stock (all versions). Without it the internal timer is always waking up the phone to check on network status which really isn't needed. I also have gotten away from using the hi-cap so on could use cases

I actually didn't look maybe a little less than an hour. Did surf for a while and paid some bills a few phone calls and the flat spot on the graph was over night so it would say very light use. I usually use my phone a lot more but forgot my charger at work so I was deliberately used it conservatively. The dashes below the graph are the wake times.

I'm getting pretty much the same with data turned off (sync for 5 mins only every hour) and not using the phone (2-3 % discharge per hour).
But the thing is, when i actually use the phone (screen, web browsing) it discharges like 30-40% per hour (non-stop use). I feel this is wrong, is it?
Fast dormancy fix applied.

We have almost no adjustments that can be made with screen on. Maybe some tweaking here or there. My biggest concern was power drain with screen off. I set out on this quest when I first got the phone in May and it had Gingerbread and I was draining like 5% / hr with the screen off. CM9 was better but horrible with screen on. I found stock to be the best balance but until I found this FD app it was still draining 1-2% per hour now it's like every 2 - 3 hrs. To get back to your question.... Is it normal? Well yes and maybe it really depends on what you are doing.. Surfing the Web... Not so much. Talking on the phone.... Playing games, etc heck yes that is normal. Try adjusting screen brightness and also an app like juice defender that can dynamically adjust cpu & screen.

dude if 24% of ur battery is standby that means you didn't use the phone... i can get 24h on standby too, and i don't run juice defender etc...

You are missing the whole point of my posting. I was promoting the capability to improve the Nitro's battery life while in standby. We Nitro users can get all the battery life we can get and it is up to you if you want to reduce stand by battery usage by over 50% by using this FD toggle app. I would suggest trying this app for 2 days and use your phone like you normally do then two days without it and see for yourself if you have better battery life. Just a heads up with the app DISABLE must be selected for it to work. Pay special attention to Android System power usage vs Cell Standby power usage. If Android System is more than Cell Standby you will have greater power usage with screen off.

my point was i get better battery life than that with no battery saver and no fast dormant tool, i use liquid nitro v6 and callibrate my battery every other week, right now this is what my usage reads.
35% battery remaining.
Usage
36% screen
18% standby
13% android os
8% phone idle
7% android system
5% media server
5% wifi
4% voice calls
3% bluetooth
2% power amp
2% google chrome
Time 1D 0H 55M 45s On battery (still35% remaining)
this battery will still last another 10 hours, total usage will be around 36 hours and i used LESS standby/idle time than you, hense i'm getting far more out of my battery with less mods. im running V20c liquid nitro V6 wind kenerl v3.0 with NO BATTERY APPS (battery apps usually consume as much energy as they save sometims more sometimes less depending on system environment) the stock battery saver on this phone doesn't even turn on until 30% battery so mine hasn't turned on yet, but all it does is disable whatever services u want once phone reaches 30%. if you want to get more out of your battery, just run an efficient rom, calibrate battery properly (ask me if u need info) and be smart with what apps you install.

i'm gonna let the battery run under 5% then take a screenshot
The FD tool actually doesn't stay resident it initiates a script that starts at boot but I would be interested in the other tools you have used as it might also work on other OS's as I am playing with 10.1 right now. One word of caution I have been told by devs on this site that battery calibration does more harm than good. Also I haven't been able to run v6 phone keeps rebooting
One more thing what battery are you using and what was your on screen time? Well I guess that's two

Yeah these batteries don't like to go all the way to zero. I've owned 9 android devices and have tinkered a lot- the conclusion I've drawn is that you get a nice placebo effect from "calibrating" the battery.
i tested 3 batteries, their life on standby and running video from 100% to 0% and all 3 batteries had better life after calibration, in every test. call me crazy but it seems to work. the only explination i can come up with is that people don't do it properly. i got my battery wipe procedure from this page: i did exactly what he said to calibrate my battery i tested 3 differant batteries and it helped all 3 one of them got 15% more life on video playback and 35% more on stanby after calibration.
http://www.droidxforums.com/forum/droid-x-hacking-guides/14714-how-optimize-battery-life-speed.html
step 3 is battery calibration. EDIT -> this step is found under section 2b Operation System.
note: i am not agreeing with everything on this thread i'm just saying that i tested batteries after using those steps for calibration and they all performed better after.
side note: it would be interesting to test what the battery lifes would be if i was to wipe the battery stats in CWM whent he battery was 50% charge. then let randomly charge it without doing the proper full discharge and recharge, and see if that ruins that battery life. i suspect that it would, and this is why people think it harms the battery, im not an expert this is just an assumption. my testing was not extensive enough to prove this only to prove that the batteries i was using had better life on the roms i tested them on in both video and standby after calibration.
few things i want to point out.
i used my phone more (less standby and more screen usage)
i got longer battery life.
i didn't waste 7% of my battery on juice defender
i used more apps and media tools.
i'm using stock battery and my rom is linked in sig
i had wi-fi or data on 24/7 sometimes both
stock battery.
as i respect other peoples opinions my science background leads me to lead towards strong evidence until i see stronger evidence supporting another theory.
here is battery at 7%
*edit* for the purpose of this test i turned off the stock battery saver (the thing that turns off wifi etc under 30%) at 32% so it never even came on
I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !
I think a longer observation period (a full day / through the night) will give a better idea of how your battery performs. Use the default power settings or other batter monitoring application like GSam Battery Monitor and compare it against other users here.

Urban myths and old wives tales. Cycling the battery doesn't "improve" battery life on a Li ion battery. What you are possibly doing is making the battery meter more accurate (placement of the "high" and "low" flags that correlate voltage with "full" and "empty"). But its just a means of measurement, and this doesn't affect the battery life itself. Meaning, it doesn't "improve" battery life any more than messing with the fuel gauge in your car would increase or decrease the amount of gas in the tank.

This doesn't mean anything. The battery % is just an estimation based on battery voltage remaining versus how the phone "thinks" you are going to use it. Comparing 98% on Android versus 100% on iOS is apples to oranges. There is no standard for this, or reason to believe they are in anyway comparable.
As previously noted, 3.5 hours screen-on time with 55% drain (45% remaining) is very normal, even good. A lot of things affect battery life, not least of which is how you use your phone, and cell reception in your area. You will see a wide array of variance in the battery life people get. And since yours seems actually pretty good, I wouldn't worry about it.

Thanks [emoji3] it was actually &37 percent but that's still pretty good with the battery save g options available I should be able to exceed a full day in the event of an unplanned night out !
To be fair, I feel like Apple designs their phone where their first 20% will take forever to drop but as soon as it passed that point it falls to 0. And yes I've seen it shut down at 10, turned it back on it's at 2. Where as this phone's last 15% seems to take forever to drop.

id say thats pretty good life outta the battery. the more you use it the more its gonna drain. and those getting like 6 hours of screen on time are strictly on wifi at an office or something. if your out roaming with LTE and the such your probably not going to get 6 hours...
Intense usage on 4g with lots of camera usage and uploads music and a few phone calls. So far so good! Had more than enough when I got home to leave without changing I case I needed it

I feel the M8, and my past Android phones take a disproportionate amount of time to drop the first few % as well. Maybe not as much as what you are mentioning for the iPhone (couldn't personally comment). May have to do with the saturation charge that occurs when the battery nears full (in fact, you should actually leave your phone on charge for some time after it says full).
Also, the battery meter on any phone is far from accurate. It often can't really be trusted with be within 5 or even 10%. So that would explain why you saw it "jump" down 8%.
Yeah my point was that all these phones' measure battery differently and not exactly accurate so you shouldn't compare Apple to oranges. Oh and the jump in percentages was referring to the iPhones. If anything Android tends to jump up when turned back on lol.
