Battery discussion

Hi
I've got an HTC one x as well.
Just wondering if it's ok to using the HTC charger to charge note2??

Updated thread to battery discussion hopefully help me and other to maximise our battery usage.

I think you'll fine but it will take longer time to charge as the Note charger has higher amp

Charging slower is fine, just don't want it to stuff up / shorten the battery life.
Just that I've being feeling that my battery seems shorter standby/use time now..
Maybe becoz started using google now?
Also is there any ways to maintain the battery life? Does discharging still work?

Hey
To my knowledge its best to charge these new batteries often... it was in the old days that it was best to let the batteries discharge completely, before recharging... I've heard that this might even harm the new generation of batteries...

Yes I came across the same info when I was using my HTC one x --> charge as often.
So same for our SGN2
= charge often, no need to discharge method.
Now can anyone confirming that google now drains power more than expected?
Somehow I was getting more than 1 day of life before but now with same usage my battery can bearly make it to the next morning?

If you want a fast charge, find yourself a Nexus 7 or Kindle Fire HD charger.

So these chargers will charge faster and not harm our note2 battery?
Any perticular voltage or watts to look for on these chargers?

Thank you, the battery life depends on repeatedly charging and discharging frequency, so should try to avoid more charge when the battery power, this will shorten the service life of the battery. Mobile phone off time more than 7 days, should first will phone the battery to completely discharge, enough electricity before use

No that's just wrong!
Phone off, leave the battery atleat 50% charged.
Do not completely discharge the battery if you can charge before it's 0%
It was true for NIMH batteries, but it's a long time since we had those kinds of battery, and ofcourse NiCd batteries.

yep, what rvenes mention should be the go = no need to discharge (drain battery to 0 and full charge).
simply charge as often as possible, not letting it fall below 50%.

HTC charger should work fine.
You can charge with the computer too, usb, but it takes longer time.

[Q] Leaving my Gnex on charger ?

Is it safe to leave the phone on the charger all night ? I mean Does this decrease battery life over time ?
thanks

it will be fine. Optimally you should only charge it to 90%, but lithium dies over time anyways. I wouldnt worry about it.

When it gets charged to a certain level, it stops charging on its own.

The phone itself only charges to about 95% even when it says full so there is really no need to charge to only 90%

ok , does charging the battery from my laptop decrease battery life over time ?

Charging Overnight

Am I the only person who is some what leary of charging my phone overnight. What I mean is, will it harm the phone any by sitting there fully charged for a few hours or more?
And that raises another question or concern. Does it hurt the device by plugging in and charging a little bit throughout the day or should I let the battery drain as much as possible then plug in?
Thanks for any replies

Only with my laptop and dewalt 18volt lol. Because it is a nicad battery.

I don't think it will hurt the battery to leave on charge for an hr or two at 100%. It is recommended to not charge till you are 10% or under from what I read
Sent from my Nexus 7 using xda app-developers app

These phones are lithium batteries. Once it hits 100% or too hot to charge the circuit shuts down. Even my stupid cordless drill does this.

I actually use a lower amp charger for charging over night and I notice my battery lasts much longer than compared to the 2 amp charger it came with.

Lithium Ion batteries are in an ideal state of equilibrium when at 50% charge. If you want to maximize the overall shelf life of the battery, do your best to keep it around 50% charge and avoid the extremes like 0% and 100%. Practically speaking this is tough to do. I am frequently near a charger, so I can unplug around 60% and plug it back in around 40%. The high amperage chargers that come with the phone can add 20% in about 30-40 minutes.
So the answer to your question is, the less time your battery spends at 100% the better to maintain the quality of the battery.

LOL, I keep phone on the charger all the time. Then again, I usually have the screen on most of time.
The only danger I can think of is if someone comes out with a kernal that does SBC which can give batteries more charge, but can also damage the battery if overcharged. I haven't kept up on all the kernals, but I don't believe anyone has made any with SBC.

50% is for storage. When in use it is optimal to charge to 100% and recharge between 10-20%, ideally at the 15% warning, which is why it's there. Charging to 100% overnight wouldn't have a huge impact on battery life for a li-ion unless you left it plugged in for several days straight. All newer good quality cellphone and mobile device li-ions have a voltage regulator and charging circuit built in. When the battery reaches 90% the voltage regulator drops the input voltage so its receiving less power til 100% once it reaches 100% the charging circuit opens and stops charging the battery, once the battery begins to discharge again while plugged in the voltage regulator switches to "trickle" charge mode which puts back a small amount of power every minute or so. When "trickle" charging the input power is so low the battery can actually drain while still charging if its being used. These are safety measures to prevent damage to the phone and battery and lessen the risk of the battery exploding, but it also helps prolong the life of the battery by preventing it from constantly overcharging if you forget to unplug it or charge over night. Hope that helps explain a bit about how charging works. Its also better to charge the battery at lower amperage outside of the device. Optimal charging for a li-ion is around 750ma on an external charger or while the device is off.

This. These batteries should be above 70 precent or so as much as possible to remain efficient. Also never let it die that decreases life span.

[Q] Questions about battery life.

-Does keeping the phone plugged in via USB (when battery is at 100%) decrease battery life?
-Approximately how long should the battery last if the phone idles? If the screen is on 24/7?
-Are these batteries any good compared to the stock one?

1.) Plugging in the phone while charged does decrease the battery life as you can only charge a battery for lets say 1000 cycles or so.
2.) Battery life depends on how long you use your phone, your ROM so I couldn't say. But my phone with the screen on lasts about 8 hours (SGH-T989)
3.) Check the reviews, it has five stars so I would assume that the battery is pretty good.

Is losing about 30% battery life overnight (about 7 hours) with the screen off normal?

Ehh I wouldn't think so...unless something is waking it up every now and then like a app or something...I normally loose about 10% if that if I let it sit over night

Not at all. I would use a battery monitor app to see what's draining the battery because that's very excessive drainage.
I can't imagine how much it drains when you're actually using it...

what rom/kernel are you using?

I agree with what others here have said, but just to add a little something, I heard that for the best battery "life" its best to try and keep it between 20% to 90%. Don't quote me, I heard it on one of those YouTube tech channels, I wonder if that is true. I always thought that it was best to completely kill the battery and then fully charge it.

That's for a new battery. Only for a couple full cycles. Else it's best to charge when you hit 15-20 and charge uninterrupted to 100.

[Q] Charging M8 - power cycling?

I usually charge my HTC One M7 phone overnight and I just got a new M8. The T-Mobile rep told me that overnight charging kills the battery and that it's better to let the battery die down to 0% and then recharge. Is this true?

Draining the battery is not good for it. Better to charge with some juice left in it. I let mine die once a month only.

Is it bad to keep it plugged in when it's at 100%? Will that shorten the battery life over time?

It's no good to leave it plugged in for days and days keeping it at 100%. Its also no good to let it drain to 0%.
Charging overnight is fine, it cuts off the charger when it reaches 100%. Best practice is to have it drain no lower than 50-75% daily.
