charging basics

[bernandops]

Hello guys, i have a really simple question for you.
Should i turn off my phone first before i charge my phone ?
3 years ago i bought a blackberry bold, then the clerk told me that to preserve battery life i should turn it off before charging. And it seems to be true since i felt a decrease in battery life a year later.
I bought my One early october and since early december after the led turns green i unplugged it and turn it on, suddenly the battery rapidly dropped to 95% in a minute. Now, after i unplugged the phone after its fully charged, in a minute it says the battery is 89% like a magic.
Im really frustated with this and whats your thoughts on this ?
Please give me tips to slower the declining battery life.

1. no you don't have to turn off your phone when charging.
2. stop obsessing about the battery % indicator. it is not exact nor linear.

i suffer no hardships doing this -

How To Take Care of Your Smartphone Battery the Right Way

Just because the battery drops fast at certain points doesn't mean there is anything wrong. Best thing to do is quit looking at the battery level and simply enjoy you device. When it notifies you its low check the battery usage history then you will actually have some real info to analyse.

Yes disconnection of the charger when its full is good for overall battery life. The less time spent at over 90% or under 10% the better. Now don't over worry about this fact tho. Because most people never experience the benefits before upgrading to a new device. We are talking a +-10% nothing to get an ulcer over.

To add to the good advice the other people have stated you can try to better calibrate the percentage of your device by letting it run completely down to the point where your phone shuts off. While its off plug it in. Keep it off while its charging. Once its green turn the phone back on, still keeping it plugged in. The indicator will go green to red for a short time. Once your at 100% then you can unplug and use your phone. By running it down to zero and leaving it off and fully charging it you essentially are calibrating the device.
Currently its off, and if it drops to 90% or so within minutes theres a good chance it could do the opposite when it gets so 5% or less. It might sit there for an hour or so because the calibration is off.
Also going back to your BB days, keep in mind these batteries and devices in general were only designed to be used for 2 years.
After 2 years you will definitely see battery capacity start to deteriorate. Thats just the nature of the battery ecosysytem.
