12 Inch PB Battery is Draining - Should I revert to Tiger?

Hello Everyone,
My main computer is a desktop iMac and I continue to use my 12 inch PB as a mobile backup. These days, I use it for web browsing, email and some video (I upgraded to 1.5 GZ). I've noticed when I DON'T have the power plugged in, the battery on this thing drains like nobody's business.
Could it be Leopard? Should I uninstall and go back to Tiger?
Or, is it the battery?
I have noticed a battery suck with every system upgrade.
Any ideas?
Thanks in advance.

Yep - time for a new battery.
Betteries simply die once they have been through a few hundred cycles of discharging/recharging. They die even quicker if you try to keep them fully charged...
The above statement may be true for iBook/PowerBook batteries and the systems charging the batteries, but it's definitely not true for the MacBook batteries. Mine is in great shape with a capacity of 4933 mAh and 324 charge cycles--and it's spent the majority of the last 6 months plugged in. The computer & battery are 16 months old.

Just bought an iPhone 5s, as I turned on the phone it showed 71% of battery, I drained it to 15% and next charged it for 3 and a half hours to fully charged. Did I do any mistake ? Should have I let it to get discharged in order to fully charge it ?

Should have I let it to get discharged in order to fully charge it ? Somebody told me I should have let it discharged and then to fully charge, but I didn't do it, my iphone is working very well, the battery too but I'm worried if the battery lifespan is gonna get worsen soon if I didn't abide by the rules and procedures of battery charging.
I had problems on my previous iPhone 4s, it died because I didn't replaced the battery with a new one because my battery never worked well and I never knew it , the battery used to overheat my iPhone and it caused to damage my processor completely to death. Who does the replacement of the iphone processor? I need help how to maintain with the iphone battery. And also let me know if I did something wrong that I should get worried about or not ?!?!

Apple does not fix the iPhone 4S, they replace the phone. If not covered by warranty, called an out of warranty exchange. Cost is US $199. Make an appointment at any Apple store.
Be aware, Apple does not sell iPhone parts, thus there is no legitimate source for genuine parts.

Macbook Pro retina display 13 inch stopped charging. Charger LED also not on while plugged in. The battery fully drained off but the system can detect the charger when it was switched on.

Macbook Pro retina display 13 inch 2014 model stopped charging. Charger LED also not on while plugged in. The battery fully drained off so the system can not be started but the system can detect the charger when earlier it was switched on before draining off the charge. Charger type magsafe 60W.

Once you have examined the power inlet on the computer for dirt, and made certain that the pins on the end of the MagSafe cord are free to move in and out to make contact, there is very little you can do yourself.
You will need to visit your Apple Store (FREE with appointment) or your Apple-Authorized Service Provider (policy varies). They work on these all the time and have good expertise and lots of spare parts to try to determine the problem.

The sync icon is constantly on-screen and battery is draining really quickly.

The sync icon is constantly on-screen and my battery is draining really quickly. I can stop it by re-starting the iPhone, but is this a known problem? The sync and iCloud seem to be working properly, but I can see the battery drop by about 1% every minute.
Sync is taking place over wireless, but even if I sync using the cable, the icon remains on-screen even when iTunes tells me that the sync is complete.

Yes, iOS4, latest and a 3GS.
So, with the home button double-tap, those two apps aren't showing in the recents list?
Nope, not showing: http://d.pr/CQnR

Did you reset like this?... press the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
Did that as well, still the problem remains.
I don't know if I should really bother but I just find it weird and I think it has a slight impact on the battery time.

IPhone 4s battery suddenly drained and won't hold a charge

This afternoon the battery on my iPhone 4s suddenly began to show that my battery was drained, then shut off completely and won't charge. I've tried holding down the home button for longer than a minute and I've tried holding down the home button and the power button at the same time but it still won't turn on. I've also tried leaving the phone to charge without touching it. This is my second replacement phone (which means it's my third iPhone 4s) and I only got it in October. It's hard to believe that it's the battery when it's relatively new, but I know that's a possibility. Anyone have any suggestions of what else I should try before I go into the Apple store yet again for a phone issue?

Ok, thanks for that info. Well I know this probably isn't what your going to want to hear, not that it's necassarily bad advice. I would suggest taking your phone into your nearest Apple Store, make an appointment with the Genius Bar first (it will just make things go smoother). The overheating/dying battery thing is a known problem. They'll either send your phone into get fixed, or you'll get a new phone. Just make sure to do a backup (in iTunes) first, as that way you'll have the most recent info to sync to should they replace your phone.
You can also call 1(800)MY-IPHONE. see if they have any ideas, but I think you'll find they'll reccomend the same thing.

How long does it take for Iphone 5 battery to drain? its stuck in recovery mode

how long does it take for Iphone 5 battery to drain? its stuck in recovery mode

Well, the two questions you've asked aren't really related, but that being said, you should probably plug it in. You're going to have to restore the software to the device via iTunes.

Battery keeps draining with clamshell is shut with OS X Mavericks and wi-fi dropping.

I have seen numerous ariticles of folks having issues after an upgrade with their battery. When the clamshell is closed and you come back a few hours later your battery is drained. This is after making sure all apps are closed and checking energy savings settings. Reverted back to 10.8.5 and had no issues battery issues. My model Late 2012 Macbook Pro Retina. In addition when streaming movies from Vudu, with mavericks it would periodically drop connection. Again reverted back and no issues.
Any one have any ideas on this one?

When my battery is drained and I charge it, it doesn't automatically switch on

When my battery is drained and I charge it, it doesn't automatically open.

It definitely should turn on by itself. But if it doesn't, I doubt the problem is too severe. Try turning it on by holding the power button for a few seconds, like normal. If that does not work, try holding both the power and home buttons at the same time for 10+ seconds, until you see the Apple boot logo.

Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full., Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full.

You can leave the charger plugged in, as you cannot overcharge...charging automatically stops when your battery is full. Once every 2 ~ 3 months, its a good idea to drain the battery to about ~ 40%, then recharge to full. Otherwise, you can charge whenever you like & leave connected whenever you like.
Try to avoid full battery discharges, Lithium batteries don't like that & frequent full discharge/recharge cycles will eventually kill your battery.

After update to ios 5, my ipod touch cannot recharge anymore... it's out of battery now what should I do?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. The appointment is free.

How fast does a macbook battery usualy drain?

I'm just curious how fast is typical for a macbook battery to drain each time you use it. I got a replacement batter b/c my old one was a dud. This one has drained 10% (100% to 90%) in about 35-40 minutes (constant use). I'm not saying that's abnormal, I'm just curious what normal is.
Gracias!
P.S. Screen is turned on medium light and bluetooth is off (however, wireless is on).

That sounds good. If your battery drains like that you could get 4 or 5 Hours out of it. If you take good care of it you should have no problems. It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. Have you calibrated your batteryyet? You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.

Can anyone help me with this issue???

Connect your iTouch to your PC then open iTunes, if iTunes does not recognize your device, try to hold the SLEEP Button and the HOME button at the same time (iPod Reset) for a couple of seconds until the "Charging Tone sounds, now you should be seeing your device name in the iTunes " Device List". If you do, just click RESTORE and iTunes will automatically restore your iTouch to original set-up and download the iOS6 update.
Hope this helps..

How much time will i take for the battery to drain, with white screen of death?

Yesterday I updated the software of my iPod touch (4gen), and today while using facebook I got the white screen of death. I tried to holding the sleep and home buttons but I didn't help. Then I tried to connect to iTunes but iTunes does not recognize my iPod. It seems that the only solution is to let the battery drain. My question is how much time will it take for the battery to drain (I charged it yesterday). Am I damaging my iPod in anyway?( I am worried because the back is a little hot). Should Ii try co cool it by placing it in front of a fan?

Yes it will show the low battery picture. Then I just connected it to my PC and restored it.
For the cold pack I used one of these gel-packs http://www.coldchaintech.com/products/gel-packs.php ( I had them at home).
I don't think using ice is a good idea here is why:
1. If you use an ice pack you should be careful to prevent water from entering your iPod.
2. Your iPod should not get colder than 32° F which is the minimum Operating temperature. And ice is colder than 32° F.

Phone Not Starting after the battery was drained

My Phone's battery was drained and when connected to charge the phone it is not charging. I have kept it for hours but When I try to start my phone it does not do any thing. I am not sure if it is charging or not. Neither anything works please help me with this.

When connected to a power source hold down both the volume up and power button for around 20 seconds then leave it for around 2 hours then check - If this fails then unfortunately your only options are to either return your device to the place of purchase or contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/

Iphone 4 battery sometimes drains fast -- problem with Mail app?

My iphone 4 battery often drains too quickly, and I wonder if it has something to do with my Mail App.
When my phone is not playing nice, it drains at least 20% overnight while on Standby, and from 100% to 30% in around 6 hours when I use it during the day. I found a fix (http://discussions.apple.com/message.jspa?messageID=11775150) that basically says to wipe your mail account and set it up again.
This fix works, but only temporarily for me. I find that I have to keep resetting my mail every few days to get back to "normal battery" where it barely drains overnight. I only use one email account (gmail) -- could there be something going on there?
Oh, and when my battery drains fast, nothing changes when I turn off WiFi, notifications, push, etc. I usually have my mail refresh hourly.
Has anyone had this experience?
