hp extreme sr2 battery drain

Hi guys.
I have installed in my lgo2x the kernel hp sr2 and HP PerformancePack V8 Lite.
I realized that the battery consumption is very hight.
For example this night the percentage battery is passed from 100% to 94% with only 2g turned on.
My phone mount rom stock v20l and BB823.
it is normal?
solutions?

If night you mean sleep for 8hrs and it drained from 100% to 94%... I think that is normal.

but before, with stock kernel, i did not have this consumpion, i found the battery to the 100% or 99%.
is the neoblaze kernel better than hp kernel regard battery drain?
sorry for my english

1% per hour is a fact of life. The phone still has to communicate with cell towers to ensure it's on demand ready to accept a phone call/text message/email push.
Put the phone in an area with better reception and it wont have to try so hard to make a signal.

When i turn on 3g and surf,,, battery drains very fast lyk if its 90 in 1 hour it gets 30
Can i place a replacement for the battery???

Draining 60% battery while surfing over 3g for 1 hour is a bit too much, are you streaming video? try to calibrate your battery.

That's not normal. If you believe your battery is faulty hit up eBay and get one of the $2.80 ones to test.
But try a calibration first.

How do i calibrate it????
Sent from my LG-P990 using XDA App

You can clear battery stat from cwm or download app called battery calibration, charge your phone to 100% and press calibrate and use your phone till the battery is fully depleted, till it shuts down by itself. Then charge it up again and use it normally. Monitor is there is any difference after 2-3 cycles, if not, you have a bad battery.

Use [ROM] Rebuild of Leaked V20o Gingerbread Update , my battery take +24 hrs to get off.

Strange battery drops and screen flicker

I had been using Cassies Xtralite rom V8 along with Hydracore 4.3 Std for weeks and everything was fine. One day the phone restarted on its own and the battery dropped from 61% to 1% just after it restarted. Then the screen started flickering too and the phone shut down on its own. This was strange because I had just charged the phone to 100% 2 hours before that and it didn't make sense. Therefore, I charged it to full while switched off and tried again. The battery drained to around 80% quite fast and then after trying to enter recovery to clear the Dalvik cache the battery went down to 5% when the phone restarted. This repeated for a couple of days until I had to do a Full Wipe and flash the rom and kernel again. However, the battery drain and sudden battery drop after restart still remain.
I read about a fuel gauge and tried to reset it by taking the battery out for a couple of minutes after charging to 100% while switched off but that didn't help either.
Does anyone have any answers to this?
Thanks

Charge your phone to 100% and clear the battery stats in cwm
It doesnt improve battery life but improves the accuracy of the displayed battery percentage
Or try changing the rom and see if the problem still exists

some roms appear to be experimenting with battry percentage based on usage. Try another rom.
Ultimately I had to go back to gb, with partition and load bootloader and stay clear of the rom in question to fix my stuff. I dare not go back again because of this issue.
I think I had to do this cause the various roms messed with special partitions, which arent wiped or formatted properly throught cwm. Migrating between different roms didnt fix it for me. wtf.
all at own risk
edit went back and had issues again. Used above approach and it didn't work anymore. It sucks.

Thank you for your replies. I tried charging to 100% and recalibrating or clearing batt stats but it did't help much.
Actually yesterday my phone would not boot and stuck to the bootloader. I had to do a factory reset in CWM to load again but as soon as it did the phone worked for 1-2 hrs and then reached around 70% batt fast and the screen flickered and turned off on its own. Uppn restarting batt was at 5%
Tried restoring a nandroid from mid September and things are slightly better. As soon as it starts the flickering I plug it on the AC and it doesn't die, but that's not always possible. It might have something to do with the batt voltages. I had flashed a Hydracore OC version and it might have messed things up. When charging the voltage goes over 4200mV.

Hi,the very simple methode for your problem is........buy a new battery and insert it in your phone then start it and problem solved !
Very easy don't you think ?
Btw,repeatitly flash rom,kernel,or all side stuff with flashtool or like that and use your phone with high frequency kill your battery very fast !
So,
the first symptom of a dead battery is autoreboot and quick down level.
Don't try to use battery test in factory with custom rom because 80% they not support it
In this case,you have always wrong indications in test mode (batteryHealt=good/100)even if your battery is dead !
Trust me and good luck
Oh and,stay away from chinese battery with high voltage and good price !
Prefer Choose stock or mugen power
Ciao

Thanks for the replies
In fact the battery appears to be the problem indeed. I took it out and placed it on a flat table and it would spin with ease. It is bulged quite a bit. Now looking to buy the original 2500 mAh battery by Samsung and the 2700 mAh battery by Anker to have a spare

If your battery is bulged then it's a dud and won't retain charge, plus you run the risk of it bursting which will kill the phone outright.

I am having a similar issue, screen starts flickering incessantly and suddenly battery drops to 2-3% and phones restarts etc. My battery does revolve a little bit, but am unsure if that's normal or not?

Guyz,
I have exact same issue battery drops to 1% suddenly... I have posted a dedicated thread.
If anybody knows the reason leme know on my thread.

I dont use extra battery, but keeping my screen brightness at 25-30% helps. And using software like juice defender and cpu tuner definately helps me.

don't u think that using a higher power battery will harm my phone...??
Sent from my GT-S5830i using xda app-developers app

The power referred to is storage capacity in milliamp hrs. A higher figure means it lasts longer not that it may damage. A higher voltage is what could damage your phone. The larger mah figure is the equivalent of a jug vs a glass
Sent from my GT-S5830i using xda app-developers app

so u mean to say that it's safe to use higher power battery.!!??
all i have to do is to make sure that the new battery has the same voltage rating as the older one !!

Yes it will say what phone the battery fits. More mah is more time. On the subject of the thread I use a charger I got for a few pounds that takes an aa battery.living in the city I'm always close to a shop selling them.

this is wiered...
when i opened the back cover of the phone and removed the battery,
there was a sticker having model and rating and other no. !!
the rating was 3.7 V and 1100mA
but the battery is rated 1350mA !!!
i don't get this...!!! is it safe ??!
sorry if it's a dumb question..
do u still recommend using higher mAh value even when the phone is rated at 1100mA ??

it's ok ,we all here to know what unknown
i read this too
mA is milli ampere
mAh is Milli Ampere per hr
1st you have to know there is different of 1100mA as the Current to charge
2nd that 1350 mah as the Capcity of the Battery
so there is huge different in between
i have bring my multimeter and find out the following that out orginal Charger only take 510 mA to charge the device in 2 hr and half
and also test the USB cable it takes 427 mA to charge the device in more than 3 hrs
anyway the 1100mA i think is the max current that can device handle ,more than that it will damage the circuits in the phone
so take care when u buy a charge that have 1100mA max ,better like the orginal one is 700mA max

Battery on my galaxy s3lte sucks

I recently bought my s3 new and i'm disappointed in the batterylife.
Yesterday I fully charged my fone before i went to work and put it unused in my pocket and by break time more then 68% of my battery was gone i had only 32% left of battery life.
In total my fone used up to 90% off batterylife without being used. Anyone any ideas???

I Had the same issue with mine. Couldn't find anything causing the drain. In the end I got the samsung 3000mah battery and cover. A little bit thicker and heavier but man does the battery last way longer

Same here can't find the root of the problem
Got a external charger...

My battery life sucked till I installed boeflla v12.7a beta. I used to run out of battery each day with every other kernel I tried.
I'm now on v12 stable and battery life is still great. I have undervolted cpu and gpu by 0.25v and using pegasusq moderate governor.

[Q] CM7 Battery

Im on official cm7 now. Using the ace kernel (OC) beta 4. I dnt know why, but when i charge my battery, the percentage goes up very high. Like my battery is 35%, when i charge it goes straight to 61%! Also, the battery goes very low though a moment before, my battery was full! And also the sim toolkit, its also buggy when i check my balance!
WHAT SEEMS TO BE THE PROBLEM?

The problem is normal on our ace. you can't really trust the 100% battery full indicator. You have to charge it for like 2 hours without a break, then it's full. if the indicator says after 10min it's full then you know it's not
