how to take good care of you batt

good read as it seems many still maltreat their li-ion
acording to old ni-cam myths

Also, make sure you read http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!

I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

er.......what?

i believe that you have to charge your battery all the way full then use all the power until it dies then you can charge it back again
but not sure

conditioning the battery the first time you get a new phone also helps, alot of us just charge for a while them use it. all my phones i let them charge for a full 24 hours right after i get them

My battery only last 6 hours

Ugh, why don't people read the article BEFORE they comment?

Ehh, doesn't the charger uncharge when the battery is full? Like a safety thing?

Some articles say that one battery life cycle is used up everytime when a full charge is done. Other articles say that one battery life cycle is used each the battery is connected to the charger.
I have not seen one article that shows the truth with facts.

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..

Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.

batt problem
how to keep my batt good?

I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

skimmed a few parts, but thanks for the read mate, learned tons.

as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.

thanks for the info!

Only charges up to 95%

Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?

Same here
(Using SuperAosp-ST 4.4)

i have that 2

I got to 98 once !

as far as i know, its an known bug

Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.

It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%

96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%

Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?

I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.

You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.

Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there

Turn the tethering on while charging; it'll charge the battery up to 100%

I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App

Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.

On nexus s with stock rom I was able to charge to 100%

How do you handle your battery on a new phone?

Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

just charge it when it needs it, dont worry about what % its at, and dont worry about running them right down... the phone will power down before it gets to a dangerous level for the battery.
dont leave it plugged in all the time when its sat at 100, dont leave it down at 0 and just forget about it for weeks on end...
thats all you need to know

I suggest you lower your brightness to 0%, turn off the useless 3 cores, underclock to 100mhz, undervolt to 0.1v, turn off wifi/data/bt and be on airplane mode all the time and enjoy your month long battery life.

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).

I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month

If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.

u have to calibrate the battery too

Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.

I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.

Charge battery between 20% - 80%
Do not use phone while charging
Unplug charger when battery full

will using the 6x while charging does any harm ??

can using the phone while charging can harm charging port or battery ? im asking this because i was using some days ago my galaxy note 3 like this one day and it stopped charging and was dead..

I don't know about harming the port but, it will definitely hurt the battery, So I don't recommend doing this except when it is an emergency

Note 3 was launched 4 years ago. Battery would have gone bad, you would have noticed the degradation.
In some phones, especially those which charge very fast, the temperature can rise to a high level which reduces the life of the battery, but should not impact much if you are using a phone for 1-3 years. Though one needs to stop charging / using the phone if the temperature reaches very high (say above 60 degree Celsius).
Honor 6X charges very slowly while using and the temperature doesn't rise as much (as compared to other phones), hence that impact is likely going to be lower.

Generally it's not a good idea to use whil charging all the time.

I strongly suggest you to use the phone while is under charge the less that you can, especially being careful about using it in combination with mobile data/GPS services/internet browsing and apps that requires particularly usage of RAM. This because the li-polymer battery plugged on charge with the original charger of 6X, that supports fast charge and so will "push" inside it a stronger power than a normal charger, will almost immediately reach a voltage of 4.1-4.2V to ensure the fast charge service and this is the limit that you want to maintain for being sure that the battery will last the longest time. Using it under charge with mobile data or others mentioned above, will easily overcome the 4.2V limit to 4.3V or even more, depending on what you'll be using, and so the ions capacity will be reduced faster, letting them contain less energy than the original capacity while time passes by.

It doesn't but thats not a good practice in general. With continuous usage, it may get more heated that is not good for battery, phone and eventually you.
Because charging itself will hear up the phone and using it may increase further so avoid it buddy.

Hehe may be. I will take time to charge in morning or in night during dinner for 20-40% and then in morning for another 40-50% or if wake up early then may be i charge full 100%. Anything above 80 ia good for entire if couldn't charge full still have 20-30% left when reach home in night.

Almost the same here; i limit the charge to 80% with Battery Charge Limit, i wake up at morning with 79-78%, i go at work and when i come back at evening usually i have around 55-60% left due various jumps here on XDA, internet browsing, some calls and a few messages. When i go to bed i plug in the phone just for a mid-hour so it can reach 80% again, then i remove it from charge and so on.

Question Charging battery on the first days of usage - help

Hi!
I have a question.
My S22 Ultra will arrive this week and I don't know how to charge on the first couple of days/weeks.
There is the option to protect the battery and don't charge over 85%. should I use this option on these first days or charge it until 100%????
On my daily basis perhaps I'll use that option, what do you think?
Thanks a lot.

i keep it at 85% setting ever since it was introduced

PLEASE HELP!!!

Just charge it normally. You'll definitely need to have it on the charger during the initial setup.

You can use it straight from the go and not worry about anything.
My tired and true method when I first get a new phone is by calibrating the battery to run for optimal usage. I let the battery drain the first time until the phone shuts off and then charge it to 100%. I do this again one more time. After that I just charge it to 100% and let it drain and top up however and whenever I feel like it.
There's a couple of reasons for this. First battery life isn't a strong suit for this phone unlike say an iPhone 13 pro max so I'm not going to waste my time running towards a charger all the time. Secondly, the benefits of charging between 75-85 percent and 20-25 percent is negated or lost on me because I'll most likely move on to a new phone by the time the extra battery life that I've managed to squeeze out can be taken advantage of. Now if you're likely the type of person who's going to hold on to his phone until it dies or will be willing to change out the battery to continue using it, then by all means go ahead and toggle the option and follow that road..
Hope this helps..

Plug it in, charge, use it - then plug it in again etc... smartphones aren't made to last forever, after a few years they all become an obsolete junk - that's my personal opinion, you can follow any charging routines you like.

Minimum start charge battery temperature is 72F, 82-90F is better.
Never start charging if below 40F.
Best not to drain past 20%, 30% is better.
72% is a better top off number.
Regardless of how much you charge it, observe the minimum start charge temperature.
Once a battery has reached 80% of it's new capacity it is degraded and should be replaced to prevent a failure which can heavily damage the phone.
A degraded Li is more likely to fail.
Any battery swelling (rear cover bulge) is a failure, do not charge, replace asap. A failure can happen at any time in the battery's life cycle and they can happen fast.
I now replace my N10+ batteries every 1-2 years, routine maintenance.
