Confused about the battery...

Hello everyone,
I'm from Pakistan and I just switched to Mac almost 2-3 weeks ago. Since, they have proper apple authorized dealers here so I finally decided to get one for myself. I had some confusion about the battery and my system and now I'm getting very much concerned and worried as a matter of fact.
I installed coconut battery (as few people suggested me) to check my battery status. First of all, it shows the age of my Mac as 5 months, which is pretty surprising since I got a brand new one and even the condition is of a brand new one so I have no clue why did it say that.
Secondly, I would like to tell the condition of my battery:
Current Battery Charge: 3591 mAh (I'm using on battery power right now)
Maximum Battery charge: 4068 mAh
88%
Current Battery Capacity: 4068 mAh
Original Battery Capacity: 4100 mAh
99%
Additional info:
Battery-Loadcycles : 12
Age of your Mac: 5 months
Charger connected: No
Battery is charging: No
I am just concerned that my battery current capacity decreased to 99% after just 12 load cycles. Why is that? Some people tell that they have a 100% even after using it for a long time and other than that does anyone have any idea why is the age being shown as 5 months when I have only used it for 2 weeks.
I'm really confused.
Another suggestion that I want is that in Pakistan, we are having major electricity load shedding so I can't keep it on AC power most of the time so if my computer is shut-down and being charged. If the electricity goes and when it comes back and it starts charging to the point from where it left, will that waste the load-cycle or will it continue to charge it from there without wasting cycle? Does that affect the battery life? (Assuming that the computer is shut-down while being charged)
Last thing, should I use it mostly on AC power or is it better to charge it and then drain the battery and then charge it and then use. Till how much percent should I keep using on the battery power and then connect the Magsafe connector?
Please help people
I'd highly appreciate if you could answer my questions.
Thank you.

I was told that it is best to keep it plugged in and connected to the charger when you can, but if you are not able to do that then just use battery power. I just know you don't want too many cycles, which means you don't want to drain the battery completely then fully recharge it. You should calibrate the battery, which is pretty much just draining battery then recharging it, every couple of months if you keep it plugged into the charger and don't use just the battery often.

Im worried about the battery percentage while play a game on my iphone 4s.so that,i decided to play a games and charging at the same time.is it problem on my battery ? im to worried.please give a conclusion.

Im too worried about the battery percentage while playing a game on my iphone 4s.so that,i decided to play a games and charging at the same time.im too worried for my battery problem on the future.please give a conclusion.

It is perfectly fine to use the phone while charging it.

I'm confused about the apple ID transition from my aol screen name. Does it continue to use my aol email as my apple ID, converting it somehow or do I need to provide a new email address or just create a new username for the apple ID?

I'm confused about the transition to an apple ID that doesn't use my aol email to sign in. The instructions are vague and ambiguous. Any help would be appreciated.

OK, so if your current Apple ID using your AOL Username (like johndoe), then you need to log onto Manage your Apple ID and EDIT that AOL Username to a valid email address: Apple - My Apple ID
If you have an AOL email address (like [email protected]), and you are not using that as another Apple ID, you can change the AOL Username Apple ID to that. Otherwise, you can change it to any valid email address (which you will have to verify when you change to it).
Hope that clears it up. Post back if it doesn't!

Confuse about the document

Hi,all . From the document ,i had confused about the following .
Automatic Undo Management in Oracle RAC
url >> http://docs.oracle.com/cd/B19306_01/rac.102/b28759/adminrac.htm#CHDGAIFJ
Oracle automatically manages undo segments within a specific undo tablespace that is assigned to an instance. Only the instance assigned to the undo tablespace can modify the contents of that tablespace. However, each instance can read the undo data blocks created by any instance. Also, when performing transaction recovery, any instance can update any undo tablespace, as long as that undo tablespace is not currently being used by another instance for undo generation or transaction recovery
what's the meaning of above that is bold ?

Say you're running a 2-node RAC and node 2 dies. The services which were running on node 2 now get re-located to node 1. It is then possible that node 1 will perform transaction rollback/recovery and, when it does so, it will need to be able to read from node 2's undo tablespace (and maybe update the undo segment headers in node 2's undo tablespace, too).

Some questions about the battery

I have a couple of questions about the battery in general.
Is it normal that my iPod Touch 4G charges very fast? It reaches 60% in only one hour and it's fully charged before it takes two hours. I know this is not bad but I'm just worried. How can I be sure if it's really loaded?
Is it normal that the battery is very quick empty when I'm gaming? For now I'm blaming this due to the quick charge.
Is it normal that for example my battery level is at 30% and when I put on standby or something or close a game, the battery starts rising for approx. 5% even 10% sometimes?
Those are my question, I hope they are clear enough. Thanks in advance.
Regards

1. The tech specs says:
Charging times: Fast charge in about 2 hours (80% capacity), full charge in about 4 hours
2. Heavy use like gaming drains the batery fater then other use. The tech specs say:
Video playback time: Up to 7 hours when fully charged
3.. Yes, the indicate capacity tends to rise after heary draining is stopped. The battery indicator is not that accurate is affected by temperature. Heavy use increases battery temperature and when it decreases battery temperature decreases.

Has anyone else complained about the battery time provided with a busy iphone5

Here's some tips to extend the battery life: http://helpios7.com/ios-7-battery-issues/

Hello! I'd like to know about the battery. Can it lose the capacity? What can i do to prolong it life time? Full charge? How to proceed ? Thanks.

Confused about the meaning of Time Quota Types

I am learning SAP-HCM on IDES 6.0. I am confused about the meaning of Time Quota Type. I have gone thru the SAP documentation, but still not clear about it. Please help me with a few examples. How is it different from Absence Type?

Hi Gopal ,
Absences are very generic ones that we create which needs to be reflected in IT2001 and dedcution can happen.
Absence Quotas are the limited entitlement that is fixed say ur eligible for 10 days sick leave so here this is a Quota for each year and so becomes a Quota say Sick leave Quota =10 and will be seen in IT2006.
Now an absence needs to be linked to this Quota for dedcution.
An absence can be or may not be linked to a Quota.This depends on business Requirement.
Let me know if u have further Questions.
Thanks

Confused about the 'cpu fsb clock frequency' setting, etc., in cell in bios

just got a new k8n neo2-f nforce3 board with an a64 3500+ venice chip. It is properly recognized in the bios and windows as an a64 3500+ at 2.2ghz, but I'm confused about the cell menu settings in the bios. I see a 'cpu fsb clock frequency' which was automatically set at 200mhz, but the fsb runs at 1Ghz (1000mhz), so what is the 'fsb clock frequency' if not equal to the cpu fsb? Is 200 the correct setting for that? Should I need to change any of the other settings in here? I wonder, because my 3dmark03 score only went up 200 points from the same system with a AthlonXP 2500+ chip and kt4avl mobo, which seems like a low increase to me.....

I would set that to Manual in BIOS, so that you can incremently increase the CPU speed without causing a sudden crash. Each system is different and operates within the specs of not only the CPU, but system memory and PCI-E add-ins as well. Your video card is the primary driver behgind your 3DMark scores...but you haven't listed that?!

Confused about the default schema

Hi,
I am a little bit confused about the schema concept.
I want to create a new schema called APP and then create several users and roles based on the schema APP. The default schema for the users should be APP achema.
How can I make the schema APP the default schema for the new users that I am creating?
I feel that there are some schema design concepts that I have to learn. Is there any resource on the internet that I can read and learn more about oracle schema design best practices?
Any help would be appreciated,
Ali

A schema holds object definitions, and in the case of table & index objects the schema also holds the data.
A user owns the schema.
Therefore the user 'owns the definitions (including any functions, procedures, sequences, tabels, etc.)
Other users may be granted access to some, or all, of the objects in a schema. This is done through the 'GRANT ...' command. For example, consider the following steps:
1) create user app_owner
2) create table object test owned by the app_owwner
3) create user app_user
4) grant select, update, insert and delete on app_owner's test table to app_user
5) add synonyms to avoid needing to qualify the table's schema name.
done as follows:

SQL> create user app_owner
2 identified by xyz
3 account lock
4 quota unlimited on users
5 default tablespace users
6 temporary tablespace temp;
User created.
Creating objects in a schema can be done by providing the schema name, or by switching schema in newer versions of Oracle
SQL> create table app_owner.test ( t number );
Table created.
Create a userid that will access the table. Set that userid up to access the database and (for future) give it the capability to create it's own synonyms
SQL> create user app_user
2 identified by xyz
3 temporary tablespace temp;
User created.
SQL> grant create session to app_user;
Grant succeeded.
SQL> grant create synonym to app_user;
Grant succeeded.
Now give the user access to the objects
SQL> grant select, update, insert, delete on app_owner.test to app_user;
Grant succeeded.
Let's test it out. Insert by qualifying the schema name on the object, then create a synonym to avoid using schema, and try it all using the synonym
SQL> connect app_user/xyz
Connected.
SQL> insert into app_owner.test values (4);
1 row created.
SQL> create synonym test for app_owner.test;
Synonym created.
SQL> insert into test values (3);
1 row created.
SQL> select * from test;
         T

         3
SQL> Note that some people want to use PUBLIC grants and PUBLIC synonyms. This is a real bad idea if you want to ensure long term security of the data and want to host several different applications in the same Oracle instance.

Ten days away: what about the battery?

Hi,
I'm going to leave for ten (10) days, not bringing my iBook with me. It will stay OFF for all that time. What about the battery? Is it going to get stale? How much shoud I charge it before I leave?
Right now I'm really proud of it: full charge = 6:30 hours!!!!
Thanks,
Stefano.

Stefano -
I'd say ten days would be OK without having to do anything special, here are a few links that talk about battery storage and other battery related information.

Paranoid about the battery

Ok, I got my nano today and I have fallen in LOVE with it. Just wondered about the battery though. I got it out of the box, choved it on my Mac and away i went! It said it was fully charged after like an hour though - not even that? I took it out anyway, was I right to do that? Anyway, I was just thinking about this '12 hour battery life' thing, when are you likely to get this 12 hours? At a medium volume setting with minimum backlight etc?
I just think the battery will go down a lot quicker (all of my friends iPods have *not so good* batteries so didn't want this to be a continuing problem)
Thanks anyway
ijmac

I'm scared now though, this morning it said battery was empty and I needed to recharge, when recharging it didn't take 3 hours (I don't think) to recharge fully, it took less (maybe 2?)
Also, when just unplugging the charged iPod the battery icon went down a bit? When i first got my nano, i charged it for like an hour (until it said fully charged), then as the icon went to half way, shoved it i again, soon after than i unplugged it to let it go all the way down to charge fully (as people recommend)
Please don't say I've buggered up this wicked iPod =(

I spoke with Apple about the battery and they said...

it might be a software issue to where something is not installed properly in the backend in which im hoping. I talked to them for a good 20mins in regards to what alot of us are experiencing about the battery life not being what its supposed to. he said they've gotten a good amount of calls this week about the iPhone not holding its battery charge throughout the day. I asked what can i do on my end to try to fix this problem. he said to backup and restore your iPhone like you just bought it to reinstall the software.
plug in to iTunes -- backup iPhone -- restore -- when "set up or backup" screen comes on, unplug. keep notice of the battery to see how its going. if its still dropping noticably then its a battery problem, if not then it should be working as normal. i might have to drive 2hrs to get a new iPhone if this doesnt help but hopefully this will help some?

Some clearly have faulty batteries.
hopefully Apple puts out a new update quick.

Mid-2013 Macbook Air: question about the battery life

First of all, I'm sorry if these questions have been already asked, I've looked around and I've seen some answers, but none that fit my specific case.
I have had this computer since December (Macbook Air, 13'', Mid-2013), I've been using it for a month now. At the beginning, I used to use it until my battery was low (between 10 and 20%) and then charge it. Then I learnt that it's better to keep it plugged as much as possible (I have read this in other discussions and on the Apple page). The problem is that my battery is no longer a 100% of its capacity according to Cococnut Battery. It started with 99%, then back to 100%, then 98, 97... and now it varies from 97 to 98 (right now it says that my computer's current capacity is 6948 mAH). I don't know if this is normal, or if this is caused by the use I used to give to my macbook air at the beginning or by any other thing. I also have 19 loadcycles already. Besides, I have noticed that sometimes it jumps form 100% to 99% of battery pretty fast when I don't have it plugged, and I'm not sure if that happened before.
This is my first time dealing with a macbook and I don't know how these things are supposed to work, and I'm worried my battery might have any kind of problem and that's why itdoesn't have full capacity anymore, since I've been using it for only a month.
Also, sometimes it takes a little while to shut down. It usually takes 2 seconds, but sometimes it takes longer, maybe 20 seconds (first the screen turn white, then the loading icon appears and then it finally shuts down). Is this normal too for macbook airs?
Thanks for the help!

Those are only averages, for purposes of the battery 97 98 99 and 100 are the 'same thing'........theyre all estimates.
Normal on shut down, sometimes you can see a few seconds, sometimes 10, 15 seconds shut down.....depends on what and HOW much its shutting down before poweroff.   Normal.
ON BATTERY USE:
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

Confuse about the injecting entity in EJB 3.0?

Where can you apply the EntityManagerFactory is it outside on EJB or Inside the EJB? means outside EJB is use the web application or java application. i have and example.
this is inside on EJB...............
