Yo guys, so i know theres a lot of widget for battery life stats, how much time you have left, temp., battery usage, etc. but supposedly a lot of them are big battery life drainers
any specific one you peeps would recommend?
I like Battery Graph Widget:
https://market.android.com/details?id=com.minigato.batterygraphwidget&feature=search_result
Besides showing your current battery, it also graphs your battery level so you can quickly see if the Android OS battery drain bug is affecting you and you need to reboot. Plus it just looks fly.
Battery Monitor Widget, the best I've used.
https://market.android.com/details?id=ccc71.bmw&feature=search_result
https://market.android.com/details?id=com.vertiform.android.app.batteryspy
Love this one. Also tels you your % per hr of drain. So when your phones been sleeping for a while then you turn the screen on it will tell you how much a hr you loose in sleep mode. Mines 2.3%hr
I like this one
https://market.android.com/details?id=org.androidappdev.batterywidget
Battery e.t.a app.let's you know everything and shows time left on battery either in hours or exact time when battery will be discharged.it's an app + widget.i use it
I like circle battery widget myself

I have a question. My battery gets to 4200mV around 80% which means its fully charged.it continues to slowly climb to 100% after that even though it hit a full charge long before it says 100%. I tried battery calibrator but it doesn't seem to help. what should I do?
Use wifiwhen possible. Turn off all unused radios (GPS,wimax,data,wifi)
Also don't run Max brightness when screens on.

If you want a phone to last you six days, u better get a flip phone.
Unless you airplane mode the phone and never use it you will not get more than two days max, which is pointless since its not really a phone in that situation.

I think full charge is based off the mAh not mV.

I dont know how the circuit in the phone works, but when I charge up my lithium batteries for my RC car, while its charging the circuit shows a higher voltage than the battery will actually be at when its pulled from the charger. I also dont know what tells the charger it is full(or getting full) but the charger starts charging at a lower amperage the closer to full the battery becomes.

For the people telling me how to get better battery life there's not what I even asked about in the OP. The guys that said its not the mV and its the mAh that does make good sense. Is there a app or widget to watch it in real time? I have better battery by curve fish that shows mV not mAh. Thanks for the feed back guys!

Grab battery monitor widget and better batter stats. BMW updates every min, but can be set lower. BBS is on of the best apps to show what's using battery.

Thank you so much. I will try them both!
Edit-I installed better battery widget.only problem I'm having is it shows me running an 1500mAh battery. I sent the dev a email which they say to do if its showing an incorrect value. So this should be fixed to. It works great thanks again so much. I now know one more thing about my phone that I didn't before
IIRC The SAMOLED+ pixels are off when displaying black. Google pure black and set it as you wallpaper. That should help.

Also depending on how aggressive your overclock is since it will raise voltages depending on frequencies. Also syncing data is a huge battery drainer. If you kill auto sync and only do manual syncs, it will feel like night and day.

Does anyone know if charging this phone overnight will "mess up" the battery , because I use an alarm every morning and I need the phone to be on when I wake up. I checked at a lot of sites ( and of course xda too) but i couldn't find the final answer?

No it will not. It has a charge script that stops when it reaches 100% then monitors the battery after that and will trickle charge when it drops a couple of percent.
Actually this is a process used to calibrate battery when you first buy one or is the first time you buy a phone. You drain it and charge it overnight. I do this too but not recently because airplane mode allows for no percentage drop..... I don't believe it is harmful but may prove to be over an extended period as are many things. Id say just turn the phone on airplane mode and it shouldn't drop but 1-2 if any percentage.

No it is not harmful. However any rechargeable battery wears over time. I have charged my phone overnight since the September 2010 without issue.
No it will not harm it is what I discovered
Here are some sources that say it will not damage it:

A general charge overnight will not harm ur battery. But every now and then..u want to perform a charge cycle. Fully chargee it, and let it drain completely. U do this twice. It just basically resets the battery cells. Our phones use a lithium-ion battery plus..its the improved lith battery.

NO. NO. NO. Uberpinguin, the one who posts cm7, hates battery calibration, and I'll preach his message for him. Cycling the battery is stupid, it wears life, and wiping battery stats is stupid. Each battery has a specific uuid (I think that's what it is) that tells batterystats.bin what battery it is, and then it THEN locates the info it needs. Not "oh hey, my phone is calibrated for someone elses battery".

Explain ****ty battery life then when i don't calibrate it when i flash a rom.
When i flashed over to CM7 my phone was getting on average 10-14Hrs depending on usage if i was heavily using it it would be from 6-8Hrs.
After i calibrated it i went from 6-8 on heavy to 12-15 on Heavy and medium usage went from 10-14 to 18-20Hrs. And minimal use ending me up with 24+Hrs
So please explain? because i hate calibrating it but it works.
Ugo, have u ever hard tested a battery? My assumption is no. Are u aware that per manufacture and engineering specs, sometime u have to do calibration. Have u performed appropriate research? I will link 1000 sources that will stat, u should cycle battery once in awhile. Its like a pc..there is the hardware function and there is the software function. Are u an advanced mobile technician? Are u. A mobile engineer? I use to be a technician. Ur basing ur statment from someone else. Have u done this "yourself"?

Battery drain always seems terrible for a short time after flashing a new rom. It does clear up.
Letting your battery drain completely is NOT good for your phone, though I'm unaware of what how it may affect the battery itself. But as I understand it, it is not necessary in any way for the battery itself- so it's useless and doing so will only help you corrupt the data on your phone.
I've been charging mine nightly since Nov 2010 and it's fine.
Those of you with serious battery drain - do yourself a favor and try staying on the same rom for more than 36 hours.

That is an EXT4/journaling thing and has nothing to do with your phone. MTD and RFS do not have this problem. At time of purchase the Techs and Samsung recommend this battery cycling and running the battery all the way down.

i have a I9100, but the battery life is really bad, ihave to charge it up about 3 times a day.
i was wondering if getting one of thoses extended batteries (the ones which go in the phone, not the ones you plug in to the phone) is worth it?
and if they are, which one do you guys recomend?

You will get ~20% more juice with genuine battery. If you are charging your phone 3 times per day I don't think it's worth it.
P.S. What are you doing with your phone?

Wow 3 times per day? What`s your screen on time when you have to recharge? Maybe some Wakelocks?
However, a new battery the 2000 mah from Samsung can add some juice for about 2 more hours. At least for me it`s the case. With the normal battery I had about 16 h of juice, with the new one I can go with 18 h but of course depends on usage.
Hi, i get about 5 hours battery with about 3 hours screen time before I have to recharge, and is the any larger battery's then the 2000mh one?

I think that there is something wrong, 5 hours is pretty bad. Instal Betterbatterystats and look if you have wakelocks.
Ok if you watch HD videos all the time while your screen is on or you play games very often then 5 hours is understandable.
There are batteries that provide over 2000 mah but they are not Samsung certified and could damage your phone and they are significantly bigger.
Do you use any rom or any modified kernel?
So you are on your phone 6-9 hours every day How is that even possible?
You really should read some other threads before actuly posting a question about the same thing that has been repeated 100 times.
Its on the first page as well...

If you are using mobile data all the time, that is normal... You use your phone a lot! Genuine 2000 mah battery would give you another hour of use
Go to general section, you will find many configs (UC/UV) fot better battery life.

Dude,if you're not using airplane mode ,then the problem with your battery is bad network signal.On your screenshots i can see that most of the time you have no network.When you have no signal ,the phone works to find it,thus eating the battery.
Hi, i only have airplane mode turned off for about an hour, and where it says the us no network signal is because the phone is in airplane mode

5h is really short. What r u doing? Playing all the time? I world consider to restock to ICS to check if changes you made could actually degradated power efficiency.
And for sure dont mess with CPU cores - by disabling second core you loose 50% processing power and gain very little teorethical battery juice. Android needs to work longer and harder to perform tasks.

Its kinda logical your battery don't last very long.... I mean your phone never sleeps. Its almost awake all the time!
I advise u to try betterbatterystats to find out what is keeping your phone awake all the time.....
And u probely don't wanna hear this but if u can't find anything wit BBS then try a fresh install , don't install apps or do any tweaking, and keep away from changing any kernel settings..

Based on his screen shoot he's in airplane made 90% of the time... His mobile sign would be red if there was no cellular connection.
On the side note regarding the battery it might be that you might need a new battery try the 2000mah one it gives me 5hrs of screen time with around 20hrs of total use on AOKP. If not there are plenty of 3000mah batteries available that can boots your battery life tremendously and increase the bulk of your phone, and you decide. Btw based on what you said 9 hrs of sitting in front of your phone is not normal in one day. You don't even need bb to see what's causing the wake locks.... It's clearly the user the screen time on is consistent with the wake locks.

This is not needed anymore.
if the battery takes to long to kill then simply its already calibrated
many people don't know how a none-calibrated battery acts and think "battery life is great but it will get better later!"
if anyone of you happened to have a nokia phone in year 2000ish and still have it around i recommend you to go get a replacement battery for it and see for your self
unless the new battery jumps from 100% down to like 80/70% in no time then take too long to drain from 10% or something like that (in short battery acting weird)
then its already calibrated which is the case in all new phones/batteries
TL;DR
unless the battery is acting weird and not taking too long to kill then you dont need to do that

This charging a long time first usage is also an old thing from the old nicd and nimh batteries..
in fact li-po and li-ion wont even charge after they are done, overcharging them means they explode/burn or get damaged.
there are built in safety features to prevent that.
and pulling it down to 0% means nothing since modern nimh, li-po, li-ion batteries don't got the memory effect.
actually going down to 0% would only test if the low voltage cutoff works as it should or if you damage your battery.
no need for that!

Batteries that comes with the latestmpgones these day do not need to be charged for 8 hours!
Just charge it till its full and continue to enjoy it!
You can preserve the life of you battery by not fully charging it and you can damage it by draining completely. I've no source for this information.
