bought I9300 phone yesterday, and it drains battery like 15% per hour of normal usage.
so i rooted the phone to undervolt, and even undervolting im having same issue. it does not drain battery in idle mode,
but as long as the screen is turned on, the battery drains very quickly and also the phones temp goes up to almost 40 degrees.
u can see in the picture that batt drainage per hr is around 15%+ when in use and when its idel its only 2%+
its stock rom and stock kernel, can some one help me?

Not quite sure how you are undervolting with a stock kernel...
But if I am understanding you correctly, you are losing 15% per hour of usage? Meaning with the screen on you are losing 15%/hr? If that is the case you are looking between 6-7hrs of screen time per charge... and that is average to above average for screen on time for the phone.
If you do actually undervoltm it should help with the heating problems... Mine barly registers as warm now at -75mv even when playing a game...

I solved mine....
Drain your battery till it gets empty....
Then charge phone without turning it on....
Exactly 2hours 10 minutes it will be fully charged...
Then turn on phone..
Works for me.

hmmm really? its weird that this is suppos to be normal. before i had my pebble blue Tmobile version phone before, and that it only drains less than 10% with screen on, so it feels like this new phone is draining so much power.
i did undervolt with stock kernel with tegrak ultimate however its same temp with same usage i think

You could always try another kernel to attempt undervolting your phone to see if there is an effect.
I do agree that 40C is far to high for standard running temp..
Screen Brightness settings the same with your old TMobile version?
Power Saving Mode Enabled?

so if i undervolt using kernel... is it possible to re-install the stock back?
and which kernel should i use?
the tmobile one im using same setting as that.. and i dont power save.
Uninstall those korean bugged apps. Use BBS to check wakelocks and CPU states.
Than report here
okay this is my stats and I dont know whats wrong, nearly no wakelocks but 3G is draining this battery like a maniac

Hi all,
Why does my battery drains faster? I checked the battery used and "Cell Standby is 70%" could this be the reason of it?
Currently using Custom Rom OptimusXrom v1.1..
Help please..
Download Spare Parts and monitor with that.
Hi badeaioan, I'll check it later.. Thanks!
still my battery drains faster, cell radio is almost 70%.. can somebody help me here?
Install Watchdog. That monitors your app's CPU usage and warns you if it goes above it's threshold.
Also, you can try wiping your battery stats.
already wiped the battery stats... nothings happens.. still the Cell Standby is 70%.. how about yours?
20%.
Do you have SetCPU installed? Try setting a profile that lowers your maximum frequency down to 245MHz when the screen is off.
EDIT: Also, you have to note that the battery info in the about menu is not live information. It updates slowly (once in a while).
yes i have installed SetCPU. I'll try to make a profile, and monitor it.. I'll post an update tom. Thanks.. I'm planning to try UbuntuDroid if this wont work.. I already tried, amber home, prime and currently using optimus x.
Cell standby is also at 75% for me and the battery has juice for 2 days. So don't worry about it.
All the p500 phones show that cell standby is the biggest conssumer (i know 4 guys with same phone). For example on a Galaxy S the screen eats all the battery.
I figured it out!
The battery usage info menu does will not show you whether your battery is draining faster or not.
Here's how it works:
Suppose I have 5 apps: a, b, c, d, and e. Let's say cell standy is app letter a. Overall, battery usage is 100%, right? Assuming everything consumes power at the same rate, app a gets 20%.
If you have cell standby consuming 70% power, everything else consumes 30% power.
Confirm this by visiting your battery info menu. Also, you only have a problem when what's consuming more is an unnecesary app. As for cell standby, I wouldn't worry about it.
Do you have a screenshot of yours?
No I don't have any screen shots, so you mean it's ok that my cell standby is 70% sometimes more... ? My officemate's Samsung galaxy s cell standby is something like 3% - 10%.. that's why I'm thinking that cell standby is the reason why my battery drains faster?
What apps do you have there by the way? I'm guessing there are a few, or many but using only about 1-3%
If you ask me, no. Out of the 100% battery use, cell standby is using 70% of that. 30% goes to everything else.
How you use that 100%, though, is a different story.
hmm.. I see... well I guess I'll try different rom... what rom are you using? I noticed, before I go to sleep,for example I check the battery 90-95% when I woke up and check it again, the battery goes down to 50%... I wonder why... standby.. and drains that fast?

Light. Wow, that's a huge difference Try another ROM. See if that solves the problem.
Yep, that's what I'm planning to do.. I hope it'll solve my problem.. hehehe I'm just waiting for my phone to finish charging.. I'll post an update tomorrow.. Thanks again kpbotbot.. how the rom you're using? how's the battery life?
Feels like the stock ROM (which is why I like it). The only difference is that stuff under the hood are tweaked, optimized, and the like. Plus the useless apps are removed. Battery life is... adequate I can go about a day and get about 60%. I don't know how long 100% will last since I always recharge.
PS - In case you're wondering why I reply so fast, it's because I have nothing to do at home since I was advised to rest for at least a month after release from the hospital xD
Try battery saving apps like juice defender.
Im using juice defender with ultimate juice and use its mobile data toggle widget to switch off my internet when I dnt use it..
hmmm..actually I was.. hahahaha.. now I know why you reply so fast.. Thanks dude.. get well soon..
40% it's a normal value?
I don't know why your battery drains so fast (50% over night is tooo much) but right now for example in "battery use" menu I have:
13h 50m since unplugged
Cell standby 78%
Android system 13%
Display 5%
Voice calls 4%
Android OS 2%
I think this is normal.
my battery drops about 10% an hour in my pocket....
when i look at battery usage it say my screen caused 70+% of my draining.
How can my screen drain so much when its only been on less than 1 min....
downloaded different roms stock 2.1, stock 2.2, 2.2 superclean.
All drain extremely fast and my battery manager keeps on saying its my screen..
Its on automatic settings!!!!
do i need to calibrate my battery? thanks in advance.
edit*
could this be a wakelock?
When you reset batt stats, it just adjusts it so the percentage is "correct", it won't affect the drain
im almost positive its wakelock....do you know how i could fix that?
*edit*
looked up spare parts and it is not wakelock......i dont understand why my screen is eating so much battery while its not even on!
10% an hour just sleeping!!!!!!! 25-35% while surfing the web, this is lame.
Today I disabled the ambient light sensor and just went back to adjusting brightness manually. 13 hours after unplugging from the wall and I'm at 50 percent.
I also have auto rotation turned off.
Sent from my SCH-I500 using XDA App
turned auto rotation off and rebooted my phone a total of 3 times after installing my rom.
now after 2.5hrs im at 95%!!! The screen does not drain my battery anymore when sleeping....but if im using my screen my battery still depletes extremely fast. like 5% every 30min. still it will last me more than enough for 18hrs with moderate usage. problem solved, but don't know how. rebooting did the trick...

I'd pay good money for battery life like that. Mine is running superclean 2.92 and it'll die with screen on within 3 hours every time.
What ROM are you running? Radio version? kernel?

running sc 2.9.2 non voodoo....and stock from what i can tell.
i dont know why but serouisly rebooting my phone a couple of times after installing got my display from draining my battery in sleep....i have no clue how, but it did.
just played angry bird for 30min, 5% drop.....with screen on auto... im at 81% at 4.5hours..... its to good right now! lol.
my phone was at 50% in sleep within 4 hours this morning!! amazing.
I'm getting horrible battery life too. Been searching for an answer. My display is using 90 percent of my
Battery in my pocket?

Check to see if your GPS is on, I'm using SC and voodoo kernel, was getting phenominal battery life until a couple days ago, phone wouldn't sleep. After banging my head against the wall for an hour or so it came to me that I had used google maps to see if it would lock my location and forgot to turn GPS off after. Shut GPS down and all is good now!
Have a Telstra S2 on stock carrier ROM
Experiencing random reboots sometimes even on idle.
Last night I ran stability test to check for RAM and actually the test ran for 5 hours before the battery ran out even though my device was fully charged the beginning and connected to the wall charger
However the device got to 61 degrees temperature!
I emailed the dev and he said its a concern the device is getting that hot and that also that the battery is draining that quickly that it can't keep to keep device charged.
Suggests I should RMA it. What do you guys think?
You stressed the device to it's maximum extent and it ran for 5 hours, so 61°C is VERY NORMAL IMO. No question of RMA and else. And also that is the temperature of the Battery, if that were of CPU I'd like it too
Regards.

Yeah ok that seems fair enough but still I am troubled by these random reboots which I still think I am going to need to RMA for? Shouldn't be happening should they?
Still has the huge battery drain though even when not running the stability test
After you have had the battery drain for a few hours, post up a screenshot of the battery usage page.

Sorry to ask a probably popular question but search on the XDA app is very meh.
Phone idle will always be the top battery killer for the average user. That's just because the phone is isle more than awake most of the time.
You can get an app like setcpu and have a custom profile to underclock your cpu while you're not using your phone though

What do you call murdering?
Is your battery dead in 2 hours, or do you see idle as the top user after 12 hours with 70% left?
Why don't you charge the phone while on. When 100%I turn it off. (Don't unplug power in this whole process ) then pull battery. In a couple seconds you will see a battery with a ? In it. Then place the battery back in. It should say 5%. Let it sit for 3-4 hours. Boot to recovery and while battery status. If no recovery, boot to os and wipe battery status. Then phone idle ( the phone only shows "phone idle" to give you will a total of 100% since before your battery once had about 60% of normal battery life. Now that you have alot Battery, phone idle is a much smaller % than you had before.
Not murdering but in a 2hr space 50+% of my battery is eaten up due to Phone Idle.
I'll try that fully charge trick tomorrow. Thanks.

Before I did that I had ..... 4 hour talk time max. Now im 6+hrs. You'll see. Thank me later
Put your battery in the witness protection program. But seriously if in 2 hours ~50% is gone, I don't think its phone idle. Also something to consider is terrible reception eats battery. And 4g even though its not true 4g those higher speeds come at a cost. I think you can guess what the cost is.
I voided my warranty.

Even if I heavy grind on the phone until its dead.. it will not have a whole lot of battery left, nor will idle consume so much of his battery. So he needs to try the basics of battery maintenance first.
Sorry guys I described that horribly.
I mean of OVERALL drain 50% is Phone Idle. Not 50% battery life.

well now that you describe it like that, use the search and read up on the many threads about phone idle. peeps can't seem to wrap their head around it. and read up on display time too.
Phone Idle should be the remainder of everything else draining your battery, basically the minimum power draw. If you add everything up you should end up with about 100%. I say "about" because android rounds the numbers up/down to whole numbers.
If your phone idle is at 50% you're doing bugger-all with your phone. So long as your actual battery life is normal then there's nothing wrong. If your battery life sucks, then possibly your battery is dead/dying or something like the minimum CPU frequency is set higher than normal causing a constantly higher power drain.
Well as long as he followed the steps. Phone idle will not take such a high % of battery usage on the battery manager. If he talked on the phone for an hour and did pandora for an hour. You would see idle would take a small % vs the talk time and pandora streaming combined/separate.
Hi guys,
I'm using GingerMod v0.3 with the default kernel (ninphetamine 2.1.3).
My battery was at 100% when i went to sleep. After about 8 hours when i woke up, it dropped to 92%. Is that normal?
I have turned off automatic sync as well as gps. Even "Back up my data" and "Automatic restore" was off. Display was at a minimum 3%. Most of the battery % was used up by Android OS.
given the percentage of the draining 8% over 8 hours i quess is pretty good. I quess different rom + kernel produce different effects. Yours is considered ok.
ya the drain is quite normal

1% an hour during sleep mode is considered good? i had the impression that it would only drop 3-4% during sleep.

More than good I'd say. And you never can have a constant rate, one night it will be 3-4%, other night it will be 9-10%, depends on the processes running at that period. If you have Better Battery Stats installed then you will be able to see what had cost that extra drainage under Partial Wakelocks section.
I normally have 3-4% drain in an overnight period of 8-9 hours, but yesterday it was 15%. Then I saw it was Camera360 Ultimate which was running and searching for GPS!
Regards.
That's about similar to what i get on standby with data enabled so yeah good battery there/
Thats good ? Mine drops 1 percent overnight (+-10 hours) with original battery Or stays at 100 until morning when I wake up with 2000mah bat... Data and wifi turned off.
But I presume thats just me being battery friendly user
I tried better battery stats and it seems the Email app is consuming the most resources during sleep. hmm...
