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.

that would kill the battery life fast, yea u wont run out of battery soon but keep it up and ur battery is gonna die on u after talking for 1hr

er.......what?

[kevinutz]

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

This is the exact opposite of what this article says.

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

[black50z]

My battery only last 6 hours

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.

[Austin11]

My battery only last 6 hours

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..

[xaccers]

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.

how to keep my batt good?

[big_bake]

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.

[benson666]

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%.

[Misuka]

thanks for the info!

I am of the impression that you can charge whenever you want and as little or much as you want to each time, but it is good for the battery to be fully discharged and fully charged (a full cycle) on a regular basis (like once or twice a month).

[Avid Droidery]

As I recall you shd never discharge a battery fully

Wikipedia search lithium ion battery technology. Please correct me if I'm wrong.

bad bad bad!
full cycles are not good for batteries, as I said, which do you think will do less harm? Subjecting your battery to 1A for 30 minutes, or subjecting your battery to 1A for 2 hours?

If through the day you aren't able to top up the battery's charge, so by the time you get home it is nearly empty, then the best option would be to turn the phone off and charge it over night with a low output charger such as 200mA

[hnernes]

I don't think it is possible to discharge the battery fully with the phone. The phone have an inbuilt mechanism to never discharge under the limit of the battery.

[turkish-soldier]

yes xaccers you are right!
full cycles aren't good

[Avid Droidery]

I don't think it is possible to discharge the battery fully with the phone. The phone have an inbuilt mechanism to never discharge under the limit of the battery.

Hypothetically speaking, let's say I let my charge hit 0 percent and the phone automatically shuts down.. if I were to turn the phone back on again..

I think it is possible to go beyond the safe limits and the best bet for anybody is to never let the battery go below 15 percent.

I don't think the phone would care about battery conditions during an emergency phone call either! The battery safe limit becomes life saving emergency power.

Here is another case. You wake up and your phone is off for some reason. unbeknownst to you yahoo messenger was constantly opening and restarting all night! you assume that the phone just crashed but the reality is your battery is drained!

For arguments sake, when you hit 15 percent it is time to go to low power operating mode and shut off all radios nonessential to phone operation. There is a program in the market called cpu tuner the can activate different power profiles based on battery status. Of course this is a cpu throttling app so you'll need to deactivate or uninstall any others. I find the program to be rather annoying when it switches power profiles based on screen conditions.

Even when your phone is off, it pulls a small charge from the battery to maintain state information. There may be a safe limit for that as well but what about power dissipation? Even when the battery is not in the phone it loses power over time.

Always remove your battery if the phone will be off for an extended frame of time. Say if you find urself going to jail for instance! Or maybe on an international trip and you don't plan to roam!

Good read, and yea it's never good to let your battery die completely

[xaccers]

0% battery on the phone's display will be above the minimum safe voltage for the battery, so the only way to drop below is to get down to 0% and then leave your phone to naturally discharge lower wich will take months and months and months.

[hnernes]

I will start to charge my battery more often then. Nice to be educated in this area, so that I may enjoy my phone for as long as possible.:)

[xaccers]

Heat and time generally kill batteries.
Unfortunately, as with laptops, our phones when used heavily get rather hot, not much we can do about that.
Running a high current through the battery also heats it up, so the shorter you expose it to the heat the better.

After about a year the battery can hold as little as half it's capacity due to age.
As soon as a battery is made it starts to deteriorate so don't but a spare battery until you need it.

[snorfonius]

Aren't those guys missing something? If you charge early (before running out), let's say at 40%, you have only 60% at your diposal. Which means you'll in return need to charge your battery around 1.5 times more often than you normally would. Guess it really doesn't change a lot if you recharge 10 times because your phone ran out of power or 15 times at 40%... both will wear your phone, #1 because of higher charging times and #2 because of more frequent charging.
I guess what that article really tells us is to charge whenever we feel like it. :D

Yeh its more like hit first read/ask questions later.

I agree let me find my charger and keep it in my pocket from now on!

[aloysius987]

for me when i am in school, i turn off the phone after school or during recess then i turn on. if there's really an emergensy of my mum texting me, i just put vibrate then suspend the screen.

[funkyblue04]

Good article. Thanks for sharing :)

[Hampteezy]

Definitely because the cells in the lithium pack will die.

[jackiets]

Thanks for the article. Very Interesting!

[jpeishen]

i always charge battery when it's below 5% capacity already.

[raveathon]

Good Share!!! thanks

[duwei0997]

this has any effect?
i plug the changer less than 5% too.
but i usually forget to unplug the changer :(

I always charge my battery on every occasion because don't know when i might start playing some gangster and after 1 hour, got to leave urgently only to see battery half and wont last for the journey.i think battery are better bought spare.

[coolsmarsh]

my battery is only 1230mA.the better way is to use a mobile power.

Battery lasts 1 day Eclair GTi5801, is there any problem,
I have apps installed

Good to know! thanks!

[motoelliot]

Ok, I flash a new Rom. Charge to 100. Reboot, flash batt stats. Discharge till auto shutoff. Then recharge to 100. Then use normally if it gets to "connect charger now" I recharge. If it bonkers my batt sumeday I've got a backup, 6.99 on Amazon for a stock hero battery. Done. Besides, can you REALLY "kill" your battery b4 your next upgrade?! Common non-sense, pun intended... people..
