My HTC One just got here. Do I need to charge it fully?

Or do I need to let it die completely before charging? What do I need to do?

use it fully untill it drains completely, then charge it to 100% , then use it fully 2 or 3 times and fully charge it.
then just use it like normal and charge like normal

That's an interesting dance that hasn't been relevant for over a decade. Interesting that you got a thanks but the correct answer didn't.

Please do not follow this advice. This used to be the best way to stop NiCad batteried from developing low capacity 'crystal memory' but it is not the case with LiOn or LiPo batteries, in fact, quite the opposite. Doing as he recommends is much more likely to damage the battery and even start a fire.
A LiPo shouldn't be discharged by more than 80% if at all possible. If you want to know more there are a lot of links on the interweb but here's a typical thread on stack exchange .. and a quote from it ...
http://android.stackexchange.com/qu...-first-time-charging-on-li-ion-batteries-myth
Nowadays, batteries are often Lithium-Ion or Lithium-Polymer and such batteries (as I have read many times and based on my own experience) would be stronger if you charge them often. The first time charging and "wait-until-full-discharge-before-recharge" and "don't-use-when-charging" are not applicable to these modern batteries.
Li-Ion and Li-Polymer batteries, if charged often, after about 1 month, would reach to their maximum performance, and you are recommended to charge them every time you find an outlet!

Wow, now we have the Richard Dawkins of battery advice. Well done.
Can everybody just calm the funk down and charge their batteries as and when they see fit? It's fine. Either way.
There is circuitry inside the battery that will prevent them from over charging, under charging, over discharging catching fire and generally behaving badly. There is also no memory effect. Just charge them when you think you'll need them.

Yeah just keep using it, if one day in the distant or not-so-distant future it doesn't turn on for some reason and/or seems unresponsive, it might need charging.

Hmmm .. shows how out of date I can get ... I didn't realise that the overcharge protection had reached such a state of sophistication ... Personally I never bothered with battery regimes, even in the bad old NiCad days ...
Thanks for the correction.

The overcharging prevention was first introduced to the Sensation and EVO 3D phones. I remember when I started seeing it because I would leave for work, and sometimes my battery wasn't charged fully. What it was doing was charging to 100%, then stops charging and will let it discharge 5%, then start charging again. And it would keep doing it until I took it off the charger. I've yet to see my EVO 4G LTE do that, though. Maybe it's been refined so that we don't notice it as much?

Wrong. Even early smartphones had overcharging protection. My old HTC Desire definitely had it.

On the note of over-discharging: just because there is circuitry inside the battery to prevent over-discharging doesn't mean you should ever let your phone run down to (what your battery shows as) 0%. Yes, the phone will generally shut off when the battery is left at around 3v, but it's still possible to force turn your phone on (which you should never do) after that point. Not to mention, leaving the battery at a low voltage for a significant period of time WILL affect the overall lifespan of the battery. Battery manufacturers will do what they can, but there is really no such thing as "true" over-discharge protection, as with overcharge protection, since batteries will still lose charge even when not in service.
Yes, if you let your battery run down to (what your phone shows) 0% occassionally, that is OK. But you should really only be doing that if and only if you need to re-calibrate for cell mismatches.

Hah! I still remember when I bought a mugen battery the instruction clearly says to discharge it fully and charge it fully for like 5 times to get optimum capacity Obviously I didn't do it. I am much aware of these things since good old Nokia 3310 days.

How's my charging routine?

Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!

Nothing wrong with that
You are charging twice a day though so you will half as many days until your battery dies. Still a couple of years until it reaches 80% capacity though

Well yeah, but don't worry about it. You'll get another phone by the time you notice a battery drop on this phone.

Ideally you should be charging the phone when the battery gets down to around 40% and charge it to almost full, 97%-99%

I've always felt that the less you charge s phone, the better in the end. And once its done charging, unplug it. So don't leave it charging over night. I have a timer set up so my phone charges only for a few hours a night then shuts off. When I wake up, my phone is usually in the 90%+ range

That's simply not true.

Lithium-Ion batteries are designed to be used - not to be used as permanent storage (thats why batteries in always-coorded laptops die faster)
(storing li-ion batteries should be done at 50% charge, never 100% nor 0%... )
Li-ion batteries should never get below 30% and likewise never hit 100% - The reason why, is because you are stressing the battery the most in the extreme ends... an almost empty cell is stressed when it has to deliver .. and an almost full cell has to charge at higher voltage to reach 100%.
So the best thing you could ever do is to charge from 30% to 95% if possible.
Regarding the amount of charges... with Li-ion you shouldn't think about the AMOUNT of charges, but the SUM OF HOURS that your charge..
so lets say you charge 500 times a year and you in total charge for 500x4 hours = 2000 hours of charging..
the battery usually last for 5.000-10.000 hours of charging ..
The reason why it is so, is because charging li-ion burns the Kathode (or Anode, can never remember) -- and when its all burned off, the battery wont charge anymore ...
Discharging too fast, also burns the Kathode (Anode) !!

Everyone is all over the place in this thread. The two things I will tell the OP to do is not leave the phone plugged in over night, and stay away from 100 and 0% and you will be fine.
But even if the OP keeps treating his battery the way he says, it will be okay. Not ideal, but still okay.
I personally try to keep the phone between 30-80%.

Does the HTC One battery stop charging after it hits 100%? There for no longer having the issue of over charging?

Overcharging??

Is overcharging the battery good or bad?
Sometimes i leave the phone on charging for abt 3 and haf hour.
Will it cause battery drains or battery health problems in future?
Thanks

Given in SONY manual: Charging your device over a long period of time, for example, overnight, does not damage the battery or the device.

New devices had protection that you cant overcharge your phone.
When batery goes to maximum capacity phone will stop charging your batt and will hold this capacity without charging battery.

Short answer: No, but not recommended.
Long answer:
All good quality phones have anti-overcharge circuitry within. So, in theory, there would be no bad effect.
However, the circuitry might be degraded, so there might be a (small) chance your battery will be overcharged.
In addition, the system might be working 'harder' knowing it's connected to AC Power, meaning higher heat generation. And heat is a battery's worst enemy.
So, even though occasional overnight charging is acceptable, one should avoid doing that. Instead, charge the battery every time you have the opportunity to. Since Li-ion battery has no 'memory effect', that is what one should do, actually.
(Of course, every now and then -- say, once a month -- you should charge the battery until full then let it drain until the phone shuts down automatically. This is to 'reset' the phone's battery watcher calibration).

[Q] Tips on charging my new z1

Hi guys. What are your ways, tips and suggestions for charging your z1?. Do you drain it completely and charge it fully afterwards? Or your the type of guy who partially charge and discharge often? And whats the best way to do the charging?. Thanks!

Okay thanks for the info!. My battery is not good. Its only 3day old and it drains very quickly. I never imagine how it drain so fast because its a 3000mah battery.

Normally it drain fast if you are playing games or browsing internet
due to it's 1080p screen,battery will be drained more fast.

I think the battery has overcharging protection, so it won't overcharge and damage it, so leaving it on charger during night, even if the battery reaches full level, is not going to cause harm.
Also, using the phone while it's charging, won't damage the battery.
Useful battery info HERE.

Thanks! I thought may battery is bad. 43% in 3hours the screen was on. XD

Best way to charge:
Quoting from http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries:
Code:
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication.
The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again.
Discard pack if the voltage does not rise to a normal level within a minute while on boost.

Does keeping the charger plugged in after 100% damage the battery?

Sorry is this has already been asked before, I did search around.
I just got my HTC One a few days ago, and after coming from a Galaxy Nexus, I think that this is a extremely good phone. Obviously I'm very careful with it and don't want to damage it, but I'm worried that the way I'm charging my device is decreasing (or will decrease) my batteries life span.
I keep it plugged in all night because I obviously I don't want to charge it during the day. So does keeping the phone plugged in all night damage the battery or does it just stop charging all together once it reaches 100%?

It doesn't damage anything. I charge my phone the same way you do and my battery lasts as long as it did the first day i got it.

There is no problem keeping the phone on charge even if it reached 100% The only advice regarding battery that I can give you is: try not letting the phone discharge to 0%. Some ppl here had issues reviving their phones after a full discharge.
