When you guys unplug your gnex from the wall... (gsm)

Does the battery go to 99% for you guys instantly? seems like mine does, as soon as i unplug it goes to 99%, just wondering if its normal or just my phone, because on my galaxy s II i would get like 30 minutes of no drain, like it would stay at 100 for a while, while this phone is like as soon as i unplug the battery is already down to 99.

Calibrate it
Mine stays on 100% for a good half an hour or so too

what is the easiest way to calibrate it? any links.. my GNEX will go 99% instantly too but overall battery drain is awesome

my battery life is TERRIBLE on this thing, it drains like crazy.. i want to calibrate it super badly but im not rooted, so i cant delete batt stats.bin , i even let it drain last night completely charged it again while it was off..still same terrible battery life. its a shame because i really really love this phone.

I'm sorry but that sounds like badly calibrated battery. Lithium-ion Batteries are -never- 100% except for a very brief moment.
It is natural that your phone displays 97%-99% when unplugged (or even when still plugged in). Batteries protect themselves like this, because these batteries cannot be charged while they are full, they will stop charging the very moment you hit 100%.

Generally you don't want your battery to be above 90% for a extended amount of time, that much voltage/capacity speeds up the degradation of the cells. So actually you should be happy, because your battery will have a longer life.

He's technically correct. LiIon batteries are happiest around 60-70% charge level. However given that your actively using a cell phone battery and your not storing it at high charge its OK.
If you really want to learn more about Lithium tech I can link you to a forum where people are VERY serious about this stuff and use them for high powered lights.

This is a known design "feature."

[Q] Battery Calibration

Hey I've read on other forums about these battery calibration apps and whatnot, just want to know if anyone has used them and know if they really do work? The wife and I both have the Dinc2 and i loaded andybonestock on both of our phones.. i use my phone like crazy and she barely uses hers. i put drellis's 21 on and UV 50 and within 15 min off the charger i'm down at most to 98 battery and she's already down to 90. her battery drains rediculously faster than mine and they're both the same exact rom's and kernel specs. Will these app's actually work or is there a real/better way to get hers working better?

Use battery calibration from the market and follow the instructions to a T. Her battery could also be defective. Try the calibration first though.

that's what i'm trying to do. I have it charging right now, at 84% then im going to run it.. just wanted to know if there was any proof it worked or any other option

I left my inc2 get charge to 100% and then use the battery calibration,i notice that my battery goes down from 100% to 97% in just 5second,the battery life is good after goes to 97%,but im not sure why goes down to 97% that fast.

Just a heads up, that is normal, your battery will never stay at 100% it doesn't charge to 100% unless you bump charge it (and that is bad for your actual battery). Having it drop anywhere from 97% to 92% is common, after that you will notice a substantial slowdown in battery drain unless you are heavily using the phone.
I added a picture of my battery life as an example of the length I am getting from the ICS Rom I'm currently using. I have my phone oc'd to 1.4ghz and uv -25 across the board. This screenshot was taken after a day full of phone calls ranging between 3 minutes and 20 minutes, moderate browser usage, moderate facebook usage and lots of texting.

Ya I knew it wouldn't stay at 100 at all but like how mine would be at 97 after 15min and hers at 90.. it just didn't add up.. she rarely used her phone and only had about 6 hours of charge, while my battery with excessive use had enough battery to last me about 16 hours. I reset battery stats and then bump charged her phone. Now its fine

glad you figured it out.
careful on bump charging, it decreases the life of the battery itself everytime you do it.

I personally don't use the apps. I've had the best luck with charging to 100%, power off and charge till green light, unplug and do one more time, boot to recovery, wipe battery, power up and unplug. That's just me though.

Charging to 100% and then powering off and charging again IS bump charging, that is bad for your battery itself, it takes away life on the actual battery everytime you do it. I said this above. You may be getting an extra half hour to an hour out of your batterys life but you are decreasing the amount of times it can actually hold a charge each time you do that, therefore ruining your battery for a tiny bit of extra battery life per charge.

I'm quite aware of what it IS. I also didn't say I do it every charge. I also know that some say its not good. I also know some say smoking can kill you. I also know I've done it on other devices with no problems. And I also didn't say for anyone to do it. I only said what I do and what has worked for me.

The smoking analogy doesn't really relate, smoking can kill you but doesn't always, bump charging for a fact decreased the longevity of your battery hence shortens the time before it does not hold a charge anymore and you have to buy a new one. I made a factual comment, I did not need a condesending response.

[Q] How to properly charge Galaxy Note 2?

How to properly charge Galaxy Note 2?
Do you let it charge overnight no matter what the battery percentage is? Do you let it go down to 40%-50% and then charge it? Maybe 10%-15% and then charge it? Can you somehow damage the battery if you leave it on the charger longer than you should to?
Thanks in advance guys!

Google is your friend here. As a rule you should try to keep your device between 25% and 70% charge to get a long life out of the battery.

Same here. I think is a myth that batteries get damaged if charging overnight, at least these days that smartphones is actually "smart" and stops the charging automatically when the battery is full.

I've always charged my iPhone 4 overnight and it had the best battery, never damaged.

How to charge:
Plug in phone whenever you want.
Charge multiple times at whatever power levels.
Unplug whenever you want.
Enjoy life.
My batteries last a year using my patented "I don't give a F" method, so it's not worth stressing over "OMG I AM CHARGING ABOVE/BELOW X PERCENTAGE!!!!!111ONEONE" Replacement batteries are cheap and easy to come by, a year is a reasonable lifespan and not stressing over it is priceless.
However, if you feel the need to freak right the heck out over your battery, just do it over there in the corner where I can't see/hear you.

This advice is for battery lifetime, not battery performance. Quote from wikipedia:
A Standard (Cobalt) Li-ion cell that is full most of the time at 25 °C (77 °F) irreversibly loses approximately 20% capacity per year.[citation needed] Poor ventilation may increase temperatures, further shortening battery life. Loss rates vary by temperature: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F).
When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, and 15%, respectively.[citation needed] In contrast, the calendar life of LiFePO4 cells is not affected by being kept at a high state of charge.[47]

Well it wouldn't exactly be full most of the time now would it
I won't deny that the maintaining a charge between 40-60% may prolong battery lifetime but the benefit of having A full battery at the beginning of everyday easily outweighs the "potential" loss of 20% battery capacity after a year. Also the hassle of maintaining a battery percentage between those limits is simply not worth it.
A new battery goes for as little as $6 here in Australia. IF there is any noticeable decrease in battery life (eg. From a loss of max capacity) then a new battery is cost basically nothing.
I charge all my devices over night if the percentage is lower than 85% and all of them still last just as long as the day I got them.

Exactly.
I mean seriously, why on earth people think too much about charging, when to charge and all, if my battery will be damaged or not, this isn't a phone of 1995! And there is no harm done if you charge overnight.
I've used all my phones like this and never had a problem with battery, not the slightest, however I don't use any phone for more than 18 months.

If overcharging does not destroy your battery and its only a myth.. then why is it included in the USER MANUAL??

Lol but it also says in most manuals that you should charge for 6 -8 hours prior to using the device even though it's unnecessary.

Same thing. By the time there is any noticeable impact on the battery most users will have a new phone.
My X10 is about 3 years old now and used by my brother. I charged it every night (sometimes even during the day as well) regardless of percentage and to this day the screen time and overall time are still almost the same as the first day. Definitely no more than a 10% decrease

[Q] Xperia Ion - Abnormal Battery Consumption

hi guys
i just got new Xperia Ion 3 days ago .... to be honest moving from Sony Erricsson C901 to Xperia Ion is amazing
the Mobile is VERY STOCK .... no additional programs or anything ... NIL
however ... it's Heating up
and the battery lasts 6-9 hours with mixed use (wifi 2-3 hours + 15 min voice call+ 30% screen brightness + screen on time = about 2-3 hours as well )
tried with Brevia Engine On and Off
and tried with Sleep timeout 15 sec and 30 sec
people told me Smart phones consume battery massively .... but charging phone 2-3 times a day ... makes it undependable and more or less like home land line ...specially when i'm used to charge my old mobile after using 3G , Music , bluetooth tethering and Camera massively every 2 days at least
so please guys help me ...
i tried to reset the phone and see if it fix the problem , however nothing yet
should i send it back to the dealer , or is this normal or xperia ion
here are some screenshots attached
thanks

Screen time 2-3 hours, then you are experiencing a normal battery life.
With heavy use [considering screen on time at least 2 hours +/-) no one here gets more than 8-10 hours I believe.

Bro. I also face this problem. Hardly I can use my ion for 2-3 hours maximum. So I tried many ways to fix it. The best way I found was flashing CM10 ROM. I can use 8-10 hours in CM10. I think you can solve it by flashing CM10. Just an idea. Many people wants to keep there warranty. If you are one of them I don't recommend it. Sorry for my bad English.

My Ion had terrible battery life when it was new. It gets much better after about 2 weeks. It takes a while for the phone to learn the battery's charge cycle.

and is there any updates soon to jelly beans ? maybe they fix the power management problem ?

the phone gets SO HOT reaching sometime to 58 c and usually 45-48 c !!!
the normal slow charger (Laptop-USB / car-charger) is extremely slow to the level that after 7 hours of charging you get only around 60% charged , and if you are using the phone while charging the battery meter goes DOWN while charging and the phone gets very hot !!!
i'll return the phone after a month of use , but my only regret is that i listened to people here who don't even have the mobile or bother to read the details about the problem -_-

There is something wrong with ur phone. Mine doesnt get hot..
I´m using it in my car, too. I charge it and use it to navigate me around, and there is no battary drain.

Does the phone overheat? My xperia s did overheat couple of times and wasn't charging even though it was.connected.
I rebooted and it solved. I had to let the phone to be cooled down before running it again.
U could try rebooting. Try hard reset if noting works.

Check if its bloated. If you can't see it well, take out your battery, put it on a table and spin it. If it spins for more than 15 seconds, then it is bloated. You will want to change it. And yes, we will require a screenshot of your battery usage

Don't take that as being 100% correct.
I have had batteries reported as healthy when in fact they were starting to show the smallest amount of bloating and starting to fail, which caused fast discharge and other problems like rebooting when forcing the camera flash, sudden drops in battery charge level etc etc...

It´s all your battery programms draining your battery. Yes they are draining battery too and if you need so much programms, don´t wounder your battery is drained so fast.
So rather than using all that battery apps better check what else is draining your battery.
