Hey what's up. I got this G2 with the latest cm7, which is build number 21 and the battery life is horrible. Like 8 hours with an hour of the display being on. I'm coming from the Epic which had pretty good battery life once calibrated.
So what's the proper way of calibrating the G2? I am using the stock kernel that comes with the Cm7 rom right now but I did try the pershoot kernel couple times and underclocked it but it still didn't help. I think all that kernel flashing messed up my battery life. So any ideas? Thanks!

Charge your phone all the way to 100% (not just until the LED turns green, which is around 90%), unplug and boot into recovery, wipe battery stats, boot back into Android and use your phone until the battery drains and your phone shuts off. Keep trying to power up until it won't any more.
Now, plug your phone in (into the wall, not a computer) and charge until full *without* turning it on. Remember, the LED turns green around 90% so you'll need to leave it another few hours after the LED changes. Once you're full, unplug and boot into Android and again use it until the battery is fully drained and you can't power up anymore and you're good to go.
Remember, after wiping stats, during the draining process *do not* plug it in to the charger or your computer as thiss will mess up the calibration.
Its a pain, and takes a day or so, but its worth it. To speed up the draining process, do some process intensive things (video watching, game playing, etc.)

Thanks for the tip. Now I have been doing some reading and saw some people recommended charging the phone while it is on when it is fully discharged the first time. You recommend while its off? Does it make a huge difference?

I don't think it would make that big of a difference; if you think about it though, you're dealing with the battery and battery only if the system is turned off.

True we are dealing with the battery but when we wipe the battery stats I think it only wipes the battery information the phone had in its system. So if we wiped the stats when it is full then let it discharge till completely empty, im assuming, you would have to charge it while its on so the phone can now learn what the battery level is and when its full and its capacity. I'm just guessing I could be wrong though. I'm just going to try both and see what happens.

I have used this method to calibrate the battery and can say that it does have a pretty big impact on battery life. +/- 20% in my case. I also find that I need to re-calibrate roughly once every month or so.
To be clear, there is not such thing as "calibrating the battery", you are calibrating the battery meter (volt meter) on the phone. Maybe its just a semantic distinction, and that is what the OP and subsequent replies are talking about. But many people get this confused, due to the old process of "conditioning" NiCad batteries, which is not applicable to modern cell phone (Li ion) batteries.
In my understanging, you aren't going to increase battery life by doing any of the above, but only making the battery meter more correctly read how much power is left. For instance, if the meter is not properly calibrated, it may read lower than it should. So people think they are increasing their battery life.
I would discourage from discharging the battery to empty. Over discharge of Li ion batteries can possibly (not often, but in a small percentage of cases) prevent the battery from taking a charge. There is a safety circuit which is supposed to prevent over discharge, but it does not always work. Therefore, Li ion batteries should not be discharged lower then 20% whenever possible. Most of us do it from time to time on accident, but there is not reason to do it intentionally. Charge the battery to 100%, drain to 20%, and repeat a couple times. This will get your battery meter plenty accurate. Draining it to empty does not really gain you anything (the battery meter is not that accurate in the best of circumstances, anyway), and can harm the battery.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Flashing a new ROM resets the battery meter. So until its properly calibrated, it will give you junk readings. This is one reason why people often jump the gun and think that a custom ROM is getting them poor battery life. Calibrate the meter, and use the ROM for a couple days, then you should get a real indication of what the battery life is like on that ROM.

I was about to post this. Letting a LiIon discharge all the way is more harmful to the battery than recharging it mid drain cycle.
I'm having a bit of battery issues, I haven't flashed a ROM or calibrated my battery meter. So I charge my phone to full while still on, unplug it and drain it until it turns off (NOT until the battery is completely drained, which could potentially damage the battery), plug it up and let it charge while off, and I should be calibrated?
Do you need to have root to be able to reset battery stats?

I'm ordering a spare battery; what is the best way to give it it's first charge / how should I condition it?
I don't think a lithium ion battery needs to be "conditioned" since it does not have the "memory" effect. It's usually the battery stats on the phone that can mess up the reading.
I would probably just make sure it is fully charged when switching them to be more accurate. But, I'm no expert...

Thanks for the reply.
I'm fairly sure I'd read somewhere that it should be fully charged before turning on the phone for the first time & after that do a couple full cycles (full-empty-full) etc..?
Yes, a full charge before using is recommended (I've also heard to let it sit on the charger for a couple more hours after it is charged helps) and maybe a few full "cycles" after that. But, like I said, I'm no expert and I, personally, have had no issues with my battery

True, it's not for the battery but for the phone stats. Lithium ion batteries are fully conditioned at the factory before being sent out. It's the last step in the actual cell manufacturing process.
Yes, I work for a lithium ion battery manufacturer. We make larger cells (not the tiny ones in a phone battery) but I have contacts and friends that work for other manufacturers that do make the little ones and they're basically all the same.
i ordered too 1800mah batteries cause i couldnt find any 1950s...they both arrived dead i waited 30 mins to charge and turn the phone on, and the other one is extremely dead it shows charging for a few minutes and then the red light turns off
so far the one i charged to 100% isnt working how i would have liked it dropped to 50% within a few hours and i charged it to 100 again and it dropped to 80 very quickly im gonna let it die tonight hopefully i get them to work good
Sorry about your bad experience.
Don't know what you purchased or the vendor, but I purchased a 3200 mAh batt from Siedio and am quite happy with it. I've been using it for over a month and get heavy use of my Atrix. High quality batteries are not cheap. Don't get the $20 dollar specials. (I have no financial interest in Siedio, I'm sure there are other vendors with quality batteries).
Battery calibration has been a challenge but I think I have a solution. I'll know in a few days as I'm presently recalibrating. It would have been so much easier if Moto had added a 5 cent current sensor to the phone.
I wouldn't worry too much about conditioning it. Just use it like you regularly would any other battery. Most horrible battery life comes from the way Android handles the battery stats. In my experience, most Li-ion batteries seem to really get their most effective use cycles after about a week or 2 of consistent usage. If you're experiencing some really drastic battery drops though, that's when it may be time to recalibrate the battery stats or start questioning the rom/radio/kernel that you're using.

Yep. However, unless you're impatient, charging it to full shouldn't do you any harm
For Lithium ion batteries, I've always put them immediately on the charger, let them go to 100%. Then unplug and let it completely die (that is, let it get so low the phone turns itself off) without pluging in. Then charge back to 100%. After that, use as normal. Doing this has gotten me long battery life, both short and long term compared to others I know who dont do that.
When I bought my phone the Bell representative said to fully charge then discharge the battery. I thought that you aren't supposed to do this though because Li-Ion batteries lose some of their maximum life when you do that. Only Ni-Cad batteries needed conditioning like that.
I could be wrong though. Would be nice to know proper procedure for this kind of thing

You're right, lithium ion batteries should not be fully discharged but it does help the first time to get the battery reading accurate. After that just charge whenever. It only really becomes a problem if you let it go dead too often.

+1. There's two reasons store reps tell you to discharge and charge the battery at least one complete cycle before using the phone. The first is that they're stuck in the past and think li-ion tech is the same as NiMH. The second and more sound reason is that it helps to set the battery statistics. If you're one of those people who loves to mod their phones right when they open the box, you could theoretically bypass this step by rooting and charging to 100%, and then just doing a manual battery recalibration by wiping the battery stats.

Yeah - if these are the Chinese jobs that came with the charger on Ebay, I got them too. They drop REALLY fast down to 5%, then I get at least another 24 hours out of them. It's crazy. I have tried to recalibrate by removing battery stats, but these haven't gotten any more accurate in several full charge / discharge cycles.
I suppose I will use them as spares, and just understand that the meter is not accurate on them. I still get a minimum two days with these cells. Will see how long they last. With batteries, you do get what you pay for.
Flattened my Xoom earlier, as I do everynow and again to full cycle the battery.
Came back to it a bit later and it had charged up to 40 odd %
Used it for a while then it suddenly said the battery was flat and switched off..
Anyone else had this, am I looking at a dead battery or should I just leave it swtiched off and on charge overnight?

It shouldn't be, lithium ion batteries don't have as intense a memory problem as the old nicad batteries...maybe just wipe the batteries stats in clockwork for good measure and take it from there. Sorry I forgot to mention that this would assume you are rooted. All my Android devices have weird jumps like that, but not usually that extreme.
cool, I'll clear the battery stats and see what it says in the morning.
Clear the stats in the morning after the full night charge not before..

Good job I checked here before I went to sleep eh
Lithium batteries do not like to go all the way down to dead (so low the device won't even start). They wear alot if you do. There is no reason to cykle them after the first time charge as there is no memory effect on them.
I had a laptop battery partially charged installed in my laptop and did't use it for two weeks. The battery went compleatly dead and when I charged it I only got like 20% into it before it said full. I had to buy a new battery.
So don't leave your XOOM with 1% battery for a long time. If you are not gonna use it for a prolonged time charge it up to about 75% before leaving it.
SEALen is correct, Lithium batteries should not be fully discharged it significantly shortens their lifespan, there is also no memory effect, the only battery type that ever did have one is NiCad.
The best way to keep a lithium battery healthy is to charge little and often, keep it topped up.

so what is the best thing to do?
is there any way of charging,dis charging ect to get the best battery life?
or should i just charg it to 100% and use it right away?
i did a charging squence with my nexus s. but duno about the Gn.
for me is to turn on the device and start working until the battery drops to 0-1%.
only then im charging it X2 then needed to go to 100%, you can make it Double if you want.
Well, this is going to be one of those threads where everyone has their own little way to care for a battery and others say their way is better, etc, etc the arguments breaking out which will result in people posting www.batteryuniversity.com in an effort to win said arguments.
Here's mine. On a brand new phone, I put the battery in, boot up, connect the charger, run it to 100%, disconnect charge, run battery all the way down, connect the charge, run to 100% and go about my life charging when I need to.
My two cents. Have no idea if it does any good, but my SGSII is going on 1 day 14 hrs on a single charge, so it must work somehow...

My way,
Turn on phone, charge it to 100%, leave it plugged for an extra 20 min, and start using it normally.
The only time I discharge a battery is after a couple of months. Because we never charge it to 100% and they start creating memory and charging less and less every time. The purpose of discharging it completely is to erase its memory. That's why when it is new, I see no point on discharging it completely. Batteries suffer every time they are completely discharged and if they are left 100% for a long period of time, thats why new batteries always come charged about 50%, to extend battery life since they may be stored for a long period of time. (ref. aviation school)
Just my 2 cents.

That hasn't been true since NiCd's in the 1980s.
Modern Lithium-Ion and Lithium-Polymer batteries have no "memory" and are actively damaged if allowed to discharge fully.

Generally because they don't know any better and they don't realise battery technology has moved on.
Because batteries "back in the days" were quite sensitive to memory. That's why we were all raised by the complete-discharge-mantra, which sticks with you forever. The next generation won't have this problem and will feel free to charge their phones when they want to. ;-)

Becouse android in itself keeps a battery log, it is from this log your device calculates the amount of battery you have left. To keep these values true (calibrated) you should do 2-3 cycles where you on purchase, discharge fully until device auto shut down, start it WITHOUT charge a couple of times and let it die to set the min value, charge up to 100%, use your device again till auto shut down... you dont have to worry about damaging your battery in this case since your device it programmed to shut down with good marginal of battery depletion. What you SHOULD NOT do is leave an empty battery uncharged for a long period of time.

Lithium batteries will be damaged if they are stored fully charged or fully discharged for extended periods of time. Thats why the battery is about half charged when its new. They have no memory effect, they just loose capacity.

Good point. While it's important not to fully discharge the battery too often, there is also the issue of calibrating the battery meter.

The whole "discharging the battery fully" thing doesn't really apply here - because nobody will ever fully discharge it. The Nexus uses a Lithium Ion cell - it's a single cell, with a nominal voltage of 3.6V. When fully charged, it peaks at 4.2V (at which point, the charging circuitry cuts off to avoid overcharging). However, when we "fully discharge" our phones, the cell only goes as low as 3.5V - and then the phone shuts off.
In reality, lithium cells can discharge to around 3.0V before any damage occurs. However, this would yield very little extra battery life. Stopping at 3.5V provides a wide safety margin (lithium cells are potentially dangerous if overcharged/discharged), whilst extending cell life.
In a nutshell - don't worry about running your phone down to 0% (unless you're putting it in storage, in which case leave it at about 60%). In fact, it's a good thing with a new phone, as cycling (charging and discharging a cell) helps to "wake" the cell up and reach it's max capacity more quickly.

i see some good ideas about charging and discharging.
but it is indeed a fact that 100% and 0%(real) isnt good for our new race of battery's.
but a few posts here already tell how and what.
and its not gonna be a thread of arguments and stuff,if we all keep it in our heads that we just want to share our tip's of how you think its the best way(and have some experience with it)
just to share some info. and not compete the info against each other.
i well know there are different ways. but its always nice to read what experience people have with it to make a choice for my own and any other wanting to know this.
and i posted here in the GN section,instead of the Android section because each phone handles battery different,and this narrows the options down to a single device :3
Just keep in mind it's not just about the battery itself it's about the software registering how much actual power the battery has at a certain time, so if the battery has in actuality 100% charge in it, and the software reads 80 then your phone will die out sooner. So charging and discharging is good because it calibrates the hardware with the software. Just remember to switch off the device then charge it so the software doesn't auto discharge when it thinks the battery reached 100%.
K i just skipped thru the posts, gonna throw in my input real quick.
Basically just run down the battery. Once it turns off, hold the power button to make sure all the juice is gone. Then charge it up to 100% and leave it there for a good hour. Now (root required) download https://market.android.com/details?...yLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd and follow the instructions .. its not exactly necessary but a nice thing "just in case" .
thats my plan anyways.

Congrats to everyone *finally* getting their beastie! I can't wait for mine...nor can I wait to PLAY with it! I did some researching on ye ole battery issue...there are a lot of different theories...so I decided to go with the "drain it out of the box, then charge" because this fits in with my extreme need to PLAY! I read it may be a good way to go to "break in" the battery, if you're of that school of thought. Some people say they do not need "broken in". Some say they need fully charged first...yada yada yada and so on & so forth. I do think the newer batteries are different than those of yesteryear in that they don't have a memory, etc, and some of the old schoolers are still stuck with that thinking. Maybe. I dunno. I'm far from any expert. (I just wanna PLAY!!! lol)
Anyone try out that Ready2Go thing thru AT&T? Kinda neat. I did it. We'll see. I just did my contacts though. The rest is taking the fun away of customizing a new toy!

I usually run it dead first then charge it to full. I don't think there is a wrong way to do it anymore. someone correct me if I am wrong and why.

A Google dev came out and said on XDA a while back (the heck if I'm going to try to find the post) that battery stats have basically no effect on anything anymore. All the same, I "grew up" on cell phones by draining them to 0, then plugging them in until 30 minutes after they show a full charge, so I've just kept doing it that way.
It seems to me that companies wouldn't send out a battery without testing it... Which would involve charging/discharging it. So I don't think there's any need to treat a battery any differently when it's fresh out of the box than you would after the "break-in" methods people have posted in here.

this is probably why I do it too.
You should not be using the same method on Lithium-Ion batteries that you do on Ni-cad... cause they ain't nicad
Just do a little research. They don't require any break-in. Not only that but it's suggested you charge often and not fully discharge if you can avoid it.
Just plug the phone in when you get it and charge it up. If you want to use it feel free, plugged in or not.
Some common tips taken from Gizmodo and Blackberry's sites:
• Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
• Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss
• Keep your battery in cooler temperatures. Hot hot heat is not good for it
• If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).
1. When you get a new Blackberry, charge it fully to 100%. There is no 120% or 130%, so once it hits 100%, it is fully charged. This normally takes about 2-4 hours for a new device. There is nothing wrong with “over-charging” the battery, however there is no real need to do so. Sometimes, new Li-ion batteries will come fully charged out of the box.
2. There is no “break-in” or “conditioning” required for the Li-ion batteries. They do not need the old “fully discharge – fully charge” routine for the initial three charges as was recommended on older battery technologies.
3. If you are a brand new BlackBerry user, keep in mind that you are likely using (or playing with) your BlackBerry much more the first few days than in normal routine use. If you think you are having quick battery discharge issues, give yourself a week or so until your daily BlackBerry usage levels off to a perceived normal amount. Don't freak out after the first one or two days if your battery depletes itself halfway through the day--You're probably using the device at a higher than normal use.

This is exactly right. Lithium Ion batteries benefit from smaller and quicker charge/discharge cycles. Actually draining a Li-ion battery to 0% and letting the phone die can decrease the total battery capacity and causes unnecessary damage to the battery. You should never do a "deep-discharge" and full recharge on a Li-ion battery.
Just pull it out of the box and use it, charge it before it hits 0%, and you'll be alright.
Heres another trick
I have done this more than a few times. Does it make a difference? I cannot say with anything more than anecdotal evidence, but I have had noticeable success and the logic makes a certain degree of sense.
Running the battery fully down often is claimed to be detrimental, and I have no reason to doubt that. Doing so once in say, 25 cycles is probably not a bad idea, although it does not do much of anything to capacity. What it does is help calibrate the battery meter. Than I add the following technique to increase the discharge time (run time) of the device:
At whatever point you finally let the battery fully discharge, do this as well:
If you have power saving feature, turn it off to get the job done. When it actually shuts down from being fully discharged, plug in and charge fully with the phone OFF. When the battery reached 100% fully charged take out the plug, wait a minute, and put it back on the charger. It will charge for 5-10 minutes more. NOW remove the plug, boot the phone, and put the plug bag in again (more charging ensues) and repeat one additional time. THIS technique seems to "Stuff" more electrons into the phone (see how scientific my explanation is? Whether I am helping, hurting or having no effect on the batteries longevity i can't say, but I CAN say is that I absolutely see longer cycles for quite some time after doing this.YMMV of course.
Whatever you consider "training" the battery, make 100% sure that the first full charge is indeed that: a FULL charge. This is one point that most documentation agrees upon. Getting the full use of the battery requires a FULL and complete first charge. Since I have no method to trickle charge, I tend to use the device while initial charging completes - I feel like that draws out the process, though why this is better. I can't say.
If only there was a definitive guide. Yes there are points in common among experts (such as running lithium ion fully charged all the time, especially warm, is terrible for them, yet almost all laptop makers let this happen by default when you run it on the charger (there is software to cycle the batteries), and some companies are including versions of this type of utility. Bottom line? batteries are cheap enough, but it's not ABOUT the money - It's about the run time. Heck - if I can't get good run time for a 3100 mA Battery, with a 2 amp charger, I better hang it up!
put the battery in, don't turn on the phone, and charge overnight. I know I know, this is the most difficult part. after that do whatever you like.
You are supposed to run the battery down every now and then(like every few months) What this does is it re calibrates the battery, separate from the android battery stat.
The batteries are tested and filled and drained then charged half way before packaged. A half of a charge is best for storage.
If your batter is dead when you open the box, exchange it. A battery sitting dead is really really bad. I have purchased a psp and some other devices that had DOA batteries and they never hold a charge for very long.
Android is the best I've seen with overcharging. Meaning there is none. The Android OS controls charging and doesn't allow the battery to fry like laptops do when plugged in all the time. I wouldn't worry about it with any Android device. Laptops should not stay plugged in for more than a few hours after full.
Running the battery down to zero (which is really 1-3%) is not "bad" what it really does is use up your charge/discharge cycle. Batteries have a certain number of charge/discharge cycles (like 300 or so) and running from full to dead to full every day will run the battery out faster; rather than charging it at half way or topping it off often.
please read post 11 and ignore anyone else who says anything to the contrary. i race radio control cars, we use lipo batteries, the system has a voltage cut off in the car for a reason. if you run them down too low, the cell will die, and will not take a charge. if you let them sit too long with a low charge, they will die. end of story. they do not need to be fully cycled like the old nicad batteries.

I say don't worry about it. The battery is replaceable and doesn't cost much. Enjoy your new toy any way you like and put battery worries out of your head.
