That is very odd. I experience the 1% every 2-3 minutes if I am using the phone with 3G turned on. Original battery. Without 3G I get an acceptable drain of probably 7 minutes or so for a drop of 1%

Really??I am using 3G for my phone as well. I was on a short trip during the Christmas Eve and have left my phone at home for whole day!!
I have found my phone drops about 10% every 12 Hours! Of course, I have received loads of greetings from my whatsapps during the time!

Okay, let's back to original topic

Sir, can you please share your experience about L7 battery usage on optimus black? any pros/cons? thank you :fingers-crossed:

ogremount · Dec 28, 2012

Sooo after some use i can report no negative effects whatsoever. Phone temperature and battery temperature is the same. Voltage of the battery after full charge (switched of from the charger) is only fractionally higher - p970 4042 mV VS L7 4085 mV.
On a side note the L7 sees the p970 battery as charged 79 %when it is actually charged to 100 on the black ( phone being switched off and charged until it shows fully charged sign).
So not entirely sure if the Black is making any use of the extra 200 mAh.

ogremount have you tried doing the opposite? Charging fully l7 battery with the OB and after put it in the l7? It shows that is fully charged?

I did that couple of times and either way it shows 100% Being charged in the L7 while switched off and put in the OB and Charged in the OB while switched off)

What i need is more precise battery measuring app . Any suggestions ?

EDIT:
Do the following at you're own risk.Even though it works for me and there is no logical reason it wouldn't work for you.

My wife got a new L7 couple of Weeks back and i have been paying with it every now and again.
As the battery on the OB is experiencing bad drain lately i thought to look for replacement. Tried other battery with no luck and than last night thought what the hell i will try the L7's battery.
Hell yeah ! Fits nicely ( but the OB battery had to be filled a bit to fit in the L7 , just in the right corner about 1mm on 1mm).
Now to the nice part. As it is a new battery the self drain is gone.
And it is 1700mAh
Although i will have to return it to my wife as she is gonna be in a shock as her phone is gonna be dead before tonight The big question for me is is the L9 battery the same size and would it fit as well .

thanks for share !

Ok folks bad news.
As i had a suspicion because of the L7 (with OB battery) only showing 87 percent charge and continuing to charge after battery showed fully charged in off state i went the other way around.
Fully charged the L7 battery in the OB and the OB battery in the L7 both in off states.
Once charged swapped them so they are both in their original phone.
And while the OB was showing 100 %the L7 was showing 87%.
I know that's not scientifical evidence but empiricly the same result two times.
So i guess the phone itself decides how much to charge the battery and not the other way around.

deadcaster · Feb 5, 2013

So, it might be impossible to use a higher capacity battery for OB???

It might appear so. Unless there is some perimeter that is responsible for it and can be changed.
At this point i am a bit lost.
Please if someone has a bit more knowledge to step forward.

Very good info. Though, I will probably go for a Mugen 1800 mah for optimus black.

So it will be fine if we are using external charger :good:

I guess so.
It definitely lasts longer when i charge it in the L7 and use it in the OB.

redeemer01 · Apr 17, 2013

then where could I buy one?

Vaiet · Apr 17, 2013

How about trying "Wipe Battery Stats" in recovery? Do you think it will help in some way?

ogremount · Apr 17, 2013

No Vaiet it does nothing wiping the battery stats. Tried it several times.
It seems to me that LG has set the charging current values in the phone . And it doesn't read or it does not reflect the actual battery capacity.
Spoke with Huexxx about it but he doesn't know either. Re-flashed Zeus 7.04 just to try but it is the same. On the other hand the L7 keeps charging the OB battery ( It reaches 87 and it is stuck there) as long as you leave it plugged-in so obviously it doesn't reflect the actual capacity either.
So if any of you folks has an idea how to make the phone read the true capacity of the battery please let us know.

Redeemer : no idea where to buy one where you are.

I think this might be the solution:

ogremount · Apr 23, 2013

The problem is i would prefer one solution without having to take the battery out to charge it.
I have portable usb charger and charge on the go.

According to this: http://www.gsmtop.ro/product.php?id_product=6846 Optimus True Hd P936 is compatible with L7 and is 1830 MAh!!! If someone knows a friend that has that phone it would be a great find as the OB lacks a decent battery with ICS and all now released!

Actually, not true...

As we can see here, they don't even have the same shape. The picture on that website is distorted, just look at the LG logo on it.

Anyway, I found this one too...

It's the battery for LG Lucid 4G VS840 (not available on my country). As it is a BL-44xx battery, I think it will fit our OB. I ordered today a cheap replacement battery for the VS840, to check if it works

edit: The LG Prada P940's battery is also a BL-44xx

Lg l7 battery fits our OB just fine :)
