About perfect battery charging time

what is the best perfect time to start charging of my iphone battery, when it reaches 20% or when it fully discharged (0% or near) ??

You can and should charge as often and as long as possible... deep discharges are hard on lithium batteries. Normal mobile use will result in the one charge cycle/month that Apple recommends. Also, you cannot overcharge the device, thus you can leave it plugged in as long as you like.

About the battery charging time.

Hello everyone,
I'm buying a Macbook pro 13 the next week and I have just one question about it.
I've seen a lot of video reviews and unboxing videos in which the owners of the computers turn them on, with out charging the laptop. In addition, when they push the battery indicator button on the left side, the battery seems to be fully charged. So my question is: Do I have to have my macbook all the day long charging itself to get the maximum battery life?
I hope you can understand my question and answer it, sorry for my English.

As long as the AC adaptor is connected the battery will charge if needed. Maximum battery life, however, is dependent upon having the battery fully charged before use. For more info see:

Lenovo Vibe Z2 Pro (K920) battery charging time

Hello everyone,
I wonder, if anyone could help me, please.
I'm experiencing an interesting issue related to battery charging procedure of brand-new Lenovo Vibe Z2 Pro (K920).
The thing is, the first two battery charging procedures took about let say 2 hours 40 minutes both.
But the third battery charging procedure took about 3 hours and 10 minutes exactly!, which I consider to be rather strange, mostly because of web reviews of this smartphone, where 2 hours and 30 minutes typical charging time is described.
I understand the fact that brand-new battery has to be initially "formatted" and it's capacity is therefore gradually increasing after few battery charging attempts.
Needles to say, after that third battery charging procedure, the battery life has been also significantly improved. I use genuine Lenovo charger which comes with the phone in the box. The only thing, which I changed since first two battery charging procedures, was turning ON "Core efficiency" in the Lenovo Battery Manager.
Could it be the reason of such extended battery charging time or is it perfectly normal bacause of gradually improving capacity for brand-new battery? Could it be defective battery? Has anyone of the owners the same experience or what is yours typical battery charging time using in-box charger?
Thanks in advance for any advice, suggestion, explanation.

Battery Charging time for a 6280

I have just bought a 6280 mobile phone but i cannot find any info on chsrging times...... can you help?

Typically from flat it may take up to 2.5 hrs to report "fully charged", however to ensure full charging the phone must be on charge for at least 16 hrs. The last 5% is only done a trickle! A new battery must be "cycled" 3 times to achieve full capacity.

Battery charging time of N72

My cell( Nseries) is almost a month old and i still need to charge it for 3 hours duration for full battery ( from an empty one) i am using genuine nokia charger. ( which has input of 230V around.
why is it taking so long?
How much time your nokia( specify model no.) takes to get fully charged??

You can buy it off ebay for £5.
It's basically a torch with a built in mobile phone charger in it. Here's apicture of it Korn.
http://www.naturalcollection.com/images/newproducts/14529-10.jpg
That picture is what it exactly what it looks like and mine looks like that.
Basically if you wind it slowly for 1 minute it gives 40 minutes of bright ( and i mean bright) light.
1 minute of slow winding also gives 15 minutes of phone standby but more depending on if using 3G or 2G bluetooth etc.
If you want to buy one go on ebay, Put in 'wind up torch'.

Battery charging time

I got a new ipod, but i feel the battery isnt lasting as long as it should, and it charged completely in 3 hours
should i be worried?

the battery life claimed by the manufacturer should not be trusted. this is why real-life situations vary the battery life of products like these.
check this link out to understand how to maximize the battery life of your iPod: http://docs.info.apple.com/article.html?artnum=61434
and if you really can't make it last, a proper solution for this is to buy an A/C adapter or Car Charger. it's a mobile device, it has to run out of juice sometime.

Battery Charging

I am using an HP Envy TouchSmart m7-j020dx. When my computer is plugged into AC power I show that the battery is "plugged in, not charging). This is true regardless of what % the battery is currently charged to. When I shut the computer down but leave it plugged in after a period of time when I restart it tells me the battery is charged 100%.
I have tried the suggestion of removing the battery and starting the computer on AC power and going to battery in device manager and uninstall ACPI Compliant Control Method Battery. Followed by shutting down the computer, reinstalling the battery, plugging in AC power and restarting. This does not change the system at all.
I have also allowed the computer to search for an updated driver, but it tells me I have the most current one.
Can you give me anyother ideas?

Disappointing Nokia Drive+ battery charging experi...

We have many threads about the phone dropping charge while on the charger so I decided to order a good quality 2.1 amp charger and use it with the OEM cable.
I drove a route that takes about 18-20 minutes with the charger and I gained about 8% battery charge in the process. This was actually quite good compared to some previous driving chargers.
Then I returned on the same route with Nokia Drive+ turned on. This is the updated version that was just released today. By the time my route was over I lost 4% battery charge while on the charger.
To contrast, I can run waze (3D turn by turn nav app) on my iPhone 4 and gain charge at the same time.

I've had a few more mixed results. However, I'm not sure if is app version related.
Yesterday I updated Nokia Drive+ from a link posted on WPCentral as they reported the update before it hit the store. That is what I ran my first test on. Then the app store notified me about an update again. It reinstalled for a second time. This time my settings had to also be reset.
Anyway, the next time I tested the battery usage I acutally gained some charge for the first half and then I lost the charge again for a net wash on battery charge. What was interesting is the half of the trip where I gained charge was rather slow driving.
The next run I did I lost 1% charge but the phone didn't get super hot either.

Sloooww Battery Charging

Hi,
I've tried just about everything I can think of with my MacBook Pro 15" (late 2008 - replaceable battery).
It starts off charging fairly quickly - saying it would take 2hrs to charge the battery fully (from nearly empty). Sounds great - Amperage is 2100mA into battery.
But, it does - it keeps slowing down and taking longer and longer to charge. Eventually to 2hrs just to charge the last 10-15% at 300mA. It means I spend 6hrs or longer fully charging my battery.
Is this for real? Is this expected?
I've reset the SMC, I've tried going back to 10.5 and a clean install from the MBP discs.
Any other suggestions?
thanks,
j.

Before you noticed the slow battery charge time, how long did it take to charge the battery?

Lenovo Idea Tab A 3300 H charging time

Hello! I have a Lenovo A 3300H tablet and after I did the update to version A3300H_A442_01_16_1409930_ROW, battery charges in 8 hours. Before the update battery charge time was about 3 hours. Is anyone experienced this problem? I expect an answer or a possible update to remedy the situation that is unacceptable!

T400 Power Problem: Flashing AC Power LED, No Battery Charge, Screen Flicker, No AC Boot

I bought a refurbished T400 less than 3 months ago. Today the power status change beeps started going off every minute or so, the power indicator light went off (while plugged in) and the battery began discharging. At the same time, the screen started flickering.
I powered down and tried draining the static by using the old trick: removing the battery and ac plug and pressing the start button 10 times and then holding on the 11th try. Didn't solve the problem.
When I use battery only, the screen doesn't flicker.
Plug in power and the screen starts flickering again, with the power LED mostly off but occasionally flickering on briefly.The battery is not listed as charging. Nothing to indicate that the power is plugged in, except for the occasional flash of the LED and the power status change beeps.
When I power down again and stay plugged in both the power LED and the battery LED keep flashing. First both are flashing green, but in a few minutes the battery light turns flashing orange.
If I remove the battery, both LEDs keep flashing. Try to power on that way and nothing happens - the LED's keep flashing, but it doesn't power on at all
Battery is new (the first one shipped wouldn't hold a charge at all; this one lists as good condition).
I don't have another Lenovo power supply to try, but the current one doesn't appear damaged or bent at all. I tried jiggling it while plugged in and there was no change.
The last thing I did before the problem began was remove a scanner from the usb port. I heard the thinkpad ports were fragile, so I am always very careful and gentle when using. I cannot see any damage to the ports.
I have about 70% battery charge left to work with, according to power manager.
My 30 day warranty is over, so I either figure this out, or I'm out the purchase price of $260., which I know is cheap for a replacement laptop, but a lot for only ten weeks of moderate use.If it's the motherboard I don't think it would be worth replacing - am I wrong? But what else can it be?
Any troubleshooting suggestions greatly appreciated. Please help! Thanks in advance for reading.

Thank you so much for the quick reply. It is a fake adapter - no lenovo written anywhere.
Now what? Should I test the unit with another adapter, or check the output of the adapter?
I hope that is the only problem, that would be wonderful. I'll update when I know more.
