stock unrooted extreme battery drain - EVO 4G General

my battery drains pretty quickly even on airplane mode. Can someone give me some suggestions? It has been 15 minutes and my battery is down to 88%...

Stock battery life isn't all that wonderful on the OG EVO. Having said that, there are plenty of ROM's available that offer better battery life over stock. I'd also look at the battery itself-might be time for a new one.

+1..I agree with FinZ28..removing bloat and improved battery life are two of the major reasons to Root and Rom your evo. If you are using it like a media player or gaming device you just need to stay by a plug though. Not even the most efficient rom can compensate for the screen being on 24/7.

No need to get complicated: ignore the top 10 % of the "100%" battery charging range - when you remove your phone from the charger you get a difficult-to-predict amount of charge between 90 and 100. Sounds like you got the bottom end of that range. Then it dropped 2% more while you played with it.
This is not extreme battery drain.
Below 90, the charge meter is relatively accurate. Tell us how long it took to get from 60 to 48, not "100" to 88.

HERE is a good explanation of why your Battery drops quickly in the first 10% .

I installed juice defender and while idle screen off it gets great battery life. This is going to be a band-aid until I get the time to root the thing and I was using an extended battery

You need a sbc kernal, extended batteries on stock kernal only charge technically to 75% and also depends on type of extended battery, I bought one off ebay that was 3500 mah, it gave me worse battery than my stock 1500... now I have a sprint 2600 I got for 15$ and I get 2 days of moderate use, so all depends also I have an sbc kernal

This is a first

This is the ffirst time I have itterally gone a whole day on one charge; got up and switched to the N1 at 910 and at around....830 I put it back on the charger at around 15 percent.
I checked email, surges the web and texted throughout the day; I could maybe go half a day on my Captivate.
I seriously thought aabout ordering some spare batteries off of eBay but I'm really rethinking that now.

My setup is the rooted, deoxed version of stock 2.3.3. Amazingly fast (just as fast and smoother than the Atrix) and obviously has great battery life.
I'm using Zeam launcher with a few Widgets, light flow and my led light (top of phone) stays lit all if the time.
Checking the stats, I used 83 megs of data that came from web browsing, twitter, downloading applications, and email and stuff.

you should be able to as long as the 1 year warranty is not up. Did he happen to mention when he purchased it?
I don't have much problem with battery life, if I am at the place with good signal receptions.
Here is my, Battery use graph, which is built into the Gingerbread.
BTW, I did re-charging during the duration.
Settings -> About Phone -> Battery use -> Tap the title bar.
My setup.
Stock GRI40
Kernel : 2.6.35.7 from android.git.kernel.org (compiled with my own taste of configurations)
Governor : Conservative
CPU speed : 128Mz - 998 MHz.
Based on my battery stats, I have an estimated battery life of nearly 48 hours if I leavr the phone alone.
With CM7 RC2 and wifi sleep policy set to never.

With sleep policy to never on CM7 RC2, does that affect battery life when wifi is turned off? Read some posts its just some bug?

set wifi sleep to never increases your battery life dramatically. if you let wifi sleep, then it switches back to 3g which destroys battery much faster than wifi. so leave wifi sleep on NEVER.
just called htc and told them i was having battery issues. they asked for my imei# told me i still had 3 months of warranty left then asked where i would like my new battery sent great customer service!

This belongs in question and answers section.
You might be able to fix this by reconditioning your battery,otherwise your battery is just getting old
It could not be getting old I just got it last month
Sent from my SGH-T959 using XDA Premium App
Thats how it is.
cm7 and miui have same problems, and its to save you from over charging, and thats some phones start heating up too much.
Don't worry about it, its for your own phones life.
Ok that's good to know and my phone charge extremely slow and sometime not at all but then I reboot and my battery life goes way up wat is that about
Sent from my SGH-T959 using XDA Premium App
Thats because your phone is mis-reading your battery's charges.
a Re-condition would help phone re-read it more accurately, but idk how you'd do that since to re condition you have to charge till' 100% lol.
Will they change rom to make it 100 cuz I don't want to go back to 2.2 rom cm7 is to good

the CM7 your using is not OFFICIAL, so the problems your facing is up to the developer to solve, not the CM team because as far as i know, they haven't even supported CM7 for us fully yet.
it's just how cm7 is reading the battery. on one revision i would get a max of 95% then 97% on another. just recondition the battery after its been plugged in for while after hitting the 97%. worst case is you have to recondition your batter again after you flash another rom or it gets fixed.
Do you know what cm7 version they've used as a base for the vibrant version? The Nexus S does this by default, to protect the battery as others have mentioned.

YOU need to re-condition, YOU can fix it.
the people on MIUI or CM7 can't.
As stated its a known thing.
I used my Samsung Focus to charge a battery to 100 percent put it in my phone and it discharged to 95% then back up 97%. So the phone isnt charging the phone up all the way as it is. This is also good for the life of the battery and the battery will last longer. Also it gives and accurate reading. Sometimes with phones if it says 100 percent it is discharging thus you actually only have <95%.
I fixed the problem I just switched to best rom(trigger) then reconditioned and it charges perfect thanks for the help

This is by design and should occur on all Roms. Below is a link to a good Phandroid article tiled "Your Smartphone's Battery Gauge is Lying to You and its not Such a Bad Thing". It really does an excellent job with a fair amount of data explaining why your battery will only charge to 95 - 97%.
It boils down to three options:
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge

RECONDITION.
I told you before everytime you flash a different rom, the battery is going to be different, so reconditioning is going to help you make it more accurate reading. brah.

You may need to do it a few times.
But since you are on a 2.2.1 rom... no need to worry, when it tells you its at 97% it's actually at 100, soon when you don't notice going from 1% to 2% will take more than regular time, it'll make up for the 3% somewhere along the lines
Ok ill let u know the results of this second try and do I have to recharge when phone off

{Battery Issues} Phones mysteriously cuts off and loses charge

one min my evo is on and battery might say it's at 49% charged. then out of no where, my phone will cut off and when i turn it back on, sometimes its completely dead. sometimes, it's showing 2-4% battery life left.
WTF is going on?
Is it a stock battery from sprint/htc or one you got from eBay or any other seller?

Ive been purchasing 2000mha batteries from eBay and they have been working great for some time now.
I believe that sometimes the length of your battery life experience will depend on the way you charge it through out your day and the amount of charging cycles you've used during the life time of that battery.
Sure I do agree that certain things can be done to improve battery life, but sometimes... It's just time to discarded it and get a new one, imo anyways.

I figured that, but I didn't wanna get a new battery if it was a bad ROM flash or something.. but I'll use my extended battery when I get home and see how it plays out. I just that damn bulky Ness to that battery.
Change roms and wipe battery stats in recovery. If its still acting funky then it must be your battery. I think sprint replaces them for free if you tell them that your battery is disfunctional

Yeah, just did that. Think it was over used. Regular charge, trickle charge, over charged. It's toast.
Been running the new battery over a day now. No restarts at all. Guess it was the battery.

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?
What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted
Do you have data off?
How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

Regarding battery life

Hello
Long time Hero user who switched to blackberry and now back to android. I've had note 2 for 3 months now and I'm actually disappointed from its battery level. Not that its not enough. .it just didnt live up to its expectations
Through constant whatsapp messaging only (today) 40% drained in 7-8 hours. . I know its a long time but shouldn't it last longer or is 3g that much of a battery usage?
Also does charging with a 2a non official charger might affect my battery? And with the time frames I have available for charging I can never get a full charge. .does that matter?
And is pile stocking on applications and games affecting my battery? Even if they are not open? (Currently using go power master for that)

You can click on that little chart to see a more detailed view of your battery consumption. Your battery life is a bit on the short side (compared to mine at least), Im guessing the screen is the culprit. Do you have brightness all the way down? How much screen time does the phone get?
@Shei77
For me is battery consumption pretty fine. It depends of course what I am doing with the phone through the day. For example yesterday after whole day "playing" with phone from time to time I had around 70%. I am chargin it when I go to sleep because still if I have in the morning 30-50% it wont make it through day when I dont have option to charge it. Just to add, I have Wifi and GPS always on.
If constant messaging for 7-8 hours means the screen being on for 7ish hours, you have ridiculously good battery life at 40 percent..

As shown from your screenshot your phone signals are really bad. That might be contributing to the drain of the battery.
I think your battery life is fine :good: Usually with my note 2 i can do 4 display hours and 1 day or more of battery life. 3g/h+ always on, lumi 50% all sync on, calls, gaming and web.
This is the current on screen which is a few hours after the first screenshots
What can I do about signals? And if I have a lot of apps do they consume battery through background?
Sent from my GT-N7100 using xda premium
Really, your battery life isn't that bad. The 7 or so screen time hours you'll get if that continues, is pretty good!
And to your other questions, charger type doesn't affect battery performance. Charging time should take around 2,5 hours from 0 to 100, if you're far away from that, the charger might be at fault.

I updated it just a couple of days ago I need an expert opinion on how good my battery's time is.
^No offence, but without screen on time a battery stats is just meaningless!
So kindly post your 'Screen on' time.
@shei77: You're on H+ and you're having almost three hours screen on time, with 60 odd percent left. That is very good battery life.
'Swyped' from my GT-N7100
Maybe a bit OT, but what I have noticed is that when the phone reports fully charged, Elixir widget still displays 1600mA being charged into the device? Also, when the battery is full at 100%, the phone is still pretty warm! I don;t remember my HTC did that? It was warm, but when it reached 100% it cooled down and was not hot anymore... I tend to keep phone in charger in the evening because I use wifi hotspot....
My battery life is awesome I'm on cm 10.1 rom with uneak kernel, cm 10.1 is smooth and great performance and great on battery life,
I have attached a screen shot of battery stats...
