Which is better, charging the battery at a higher amperage or lower?

I just bought a 3rd party adapter to recharge my Touch via the AC outlet. I have an application on my touch that gives me the status of my battery. When I plug my touch via USB, the charging amperage is 500ma but when I use the AC plug, it says 1000ma. So which is better for longer battery life?

Which is better for the battery life?

Should I keep the charger plugged in constantly or use up all the battery life and charge only when the battery life is near 0% and charge until full?
I want to keep the battery life as long as possible. Thank you!

Hi: Check out the very informative article listed below for battery information.

Which is better on the battery

Bluetooth or Wifi teathering?

Bluetooth 2.1 + EDR, which the iPhone offers, operates at 2.5 mW and has a useful transfer rate of 1.4 Mbps (3.0 Mbps raw).
WiFi operates at 100 mW and has a useful transfer rate over 50 Mbps.
Thus, WiFi uses a LOT more power (40 times as much) but has higher throughput.
The cellular data connect on 3G can be up to 4.5 Mbps, but most of the time will be around 1 Mbps. So you will lose a little on speed on BlueTooth but have much better battery life.

Is it better for your battery if you let it run down all the way and then charge it? Or to charge it whenever you have the opportunity? Which is better for the life of the battery?

I was wondering it the life of the battery would last longer if you let the battery run down all the way and then charge it? Or to charge it whenever you have the opportunity even if it doesn't have a low battery? Which is better for the life of the battery and prolong the life of the battery?

I've had a iPhone 4s since March 2012, and it's battery is pretty useless now. I was using the app Battery Doctor (Battery Saver, Battery Life) by Beijing Kingsoft Internet Security software, which encourages the user to charge more often, whenever battery life drops below 100% full and greater than 20% full, and gives ratings according to the number of full, partial & overcharges done, but I'm concerned that charging like that actually results in worse battery life??
I now have an new iPhone 5 and don't want the battery to only last as short as the last one did
Any advice/comments please

Is the wall charger better for the battery then using the computer?

I was looking for things for my Shuffle to add to my Christmas list when I came across this in the Apple Store. Someones review said that this item is better for the battery as when you plug it into a computer it drains the battery, then recharges it. As to this iten which charges the empty space only and does not drain the battery before recharging. Is this true? I will give points to those who can answer.

Apparently it makes no difference to the life of the battery how or how often you charge it.
I charge mine in a USB port on the external speakers I bought (iSound) and a full charge takes about 3 hours. - this is about the same as just plugging it into your USB port on your PC.
(I tend to just top up the charge after a couple of uses)
I just find it more convenient to be able to charge it without having to power up the PC everytime.

Which is better to keep battery in the best performance ?

Which way is consider better to keep laptop battery in the best performance: 1- plug it in charge always. 2- use laptop battery without plug in electricity source when battery become full charge.

Hi
It makes no difference which way you use because if you keep the AC/DC adaptor is connected and the battery is fully charged, the battery will not be used. It will only be used if you disconnect the AC/DC adaptor.
Furthermore a battery can be recharged up to 500 times so I always work with connected AC/DC adaptor. But I would suggest to completely charge and discharge the battery from time to time. ;)

Correct way to charge the battery

I apologize if I'm repeating a question. In the manual for the Palm Pre Plus, it states that you're able to let the battery charge overnight. My phone only takes about an hour to fully charge from 20 percent. I'm afraid if I let the battery charge any longer than that I run the risk of overcharging and damaging the battery, which was the situation with my previous cell phones with lithium batteries.
Any information would be greatly appreciated. Thank you very much.

Here are a few tips for extending battery life:
Avoid exposing the battery to extreme heat and cold.
For the first 3 charge cycles, fully charge the battery overnight and allow it to fully discharge before recharging (battery conditioning).
Charge and re-condition a battery after an extended idle period.
A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).
Keep the phone, batteries, and the contact terminals clean. The contacts can easily be cleaned with a pencil eraser.
Use the battery. If possible, avoid letting your battery sit idle for long periods of time.
Use only the phone options and accessories that are really needed.

Thinkpad Yoga S1 Runs off AC but won't charge the battery

I have recently purchased an S1, which is now having an issue that I can't seem to resolve on my own. The laptop works (almost) perfectly on A/C, but doesn't charge the battery. I noticed yesterday the battery was low (which was surprising, because I had only recently unplugged it) - so I plugged it in to charge.At which point, the battery icon in the system tray stated "8% (plugged in, not charging).I've tried the following to fix this: 1) Leaving it plugged in overnight completely off. 2) Running the battery calibration (fails w/ unexpected error). 3) Tried turning off battery optimization (Option is removed in newer version of drivers, so NA to my issue). 4) Tried reinstalling the power management drivers anyway (even though I already had the newer version). 5) Holding down the power button for 30 seconds, both plugged in and not plugged in (suggestion from forum). 6) Holding down the reset button (pin reset on the mobo) for 30 seconds, both plugged in and not plugged in. 7) Charging from BIOS. 8) Letting the battery run down to 0% in BIOS, then rebooting on A/C (another forum suggestion). Now I'm just at 0% plugged in and not charging. Previously I said the computer almost worked perfectly, the almost is that the CPU is stuck at ~800mhz, even with all power management turned off (including Speedstep in BIOS) and the power profile set to high performance. Can anyone think of anything else I can try before I give up and send this thing back? It was working perfectly for the last couple of weeks or so, including getting ~ 4, 5 hours of battery life, so unless the battery failed very suddenly I can't imagine why it would just start refusing to charge.

well I replaced the battery with another one I bought (exact same model for the battery SONY 45N1705, I was hoping I would get another battery version because I notice there is an update for the other battery revision that fixes issues with battery stopped charging. http://support.lenovo.com/us/en/downloads/ds001322. I forced the bios update from 1.07 to latest 1.24 using olydbg to skip the battery check. this did not help with anything relating to the battery. now I am stuck again where I was at the beginning..... im looking at buying a board replacement.... also I was looking at replacing the power supply but I check the voltage and the amps, and it is correctly matching what is written on the back of the laptop. still getting the 0% plugged in and charging.

I bought a new ipad2 yesterday and charged the battery and then expected to get going with it but the screen only displays an image of a ubs connection with an arrow pointing to a itunes symbol. I downloaded itunes on a PC and plugged in the ipad to it but nothing changed on the PC or ipad. very frustrating. anyone else experience this or have know how or ideas to help me?

Here is my standard reply, some of which may have no relevance to your situation. Start with trying different USB ports, even a numbe of times.
1. Make sure that your device is not hidden (left hand pane). If it just reads device then toggle between SHOW and HIDE.
2. Try all the other ports on your computer, even a number of times.
3. Make sure your lead /connections are not faulty.
4. If you have another computer try plugging your device into it without taking any action, give it a moment, remove it and try it back in your other computer again.
5. Make sure you have the latest version of iTunes installed.
6. If using Widows, make sure all Windows Updates are installed.
7. Failing all that, see here - http://support.apple.com/kb/TS1538 for Windows and http://support.apple.com/kb/TS1591 for Macs
8. And failing all that put the device into Recovery mode. See here and note the paragraph 'If you restore from a different computer.... ' down near the bottom of the page -

Can you charge the battery for too long?

I know that with cell phones if you leave the charger in for too long the battery starts to lose life. Is it the same way with the macbook or did the engineers work out a way that you can keep the charger connected for as long as you want and it won't drain battery life?
I'd like to charge the battery whenever I go to sleep but I'm afraid that it will have charged too much by the time I wake up. I learned that the hard way with my cell phone, which seems to lose power much quicker than it used to.

Hi,
since Apple recommends to never remove the battery while running the MacBook on AC-power, it is the logical conclusion.

Charge the battery?

Does the Ipad need to be wifi enabled to charge the battery? Delay in cable visit.

FYI, some battery/charging info.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

It talks extensively about charging in the user guide, and how USB ports on PCs and older Macs may not provide sufficient power to charge the iPad. The user guide is available for free from the iBook store (accessed directly via the iPad iBooks app).
My iPad charges fine when plugged in to the back of my iMac, but I would always prefer to use the mains adaptor to save the strain on my USB circuits (which can wear out if used heavily to power external devices).

Does the iPod nano come with a means to charge the battery?

Yes it comes with a syncing cable that you can connect to your PC's USB ports to charge or you can connect it to an Apple wall adapater (sold seperately).

How can I charge the battery in my macbook pro on a plane

I am getting ready to take a flight to Australia. How what do i need to get to charge the battery on the plane?

You have to bring your charger with you and hope their is an electrical outlet that is compatible with your charger near the seat you are sitting in. I do not know of any other way.

Which is better, charging the battery at a higher amperage or lower?
