It is stated that lower DoD (depth of discharge) helps longevity of the battery. It also says that less-than full charge helps longevity of the battery.

So is it better to start charging somewhere around 50% and charge it to 85% instead of 100%?

How do you guys usually handle charging? any particular suggestions?

Honestly, I let my battery drain down twice and then charge it nightly. Never had any issues by doing it this way.

I charge my battery any time i feel like it is low during the day and put it on the charger when i go to bed. That is usually between 11 pm and 1 am. Unplug it around 7:15 am.

Never had issues with the battery charging to 100% or lasting for most of the day, or over a year or more.

I charge it almost every night to 100% from anywhere between 5%-50%. Been doing this with all phones since 2001 and never had to replace a battery

[loraque]

Usually the only time I charge it during the week is when it is in the car dock during the commute. Otherwise, I never charge it Mon-Fri and only barely on the weekends. Battery life is excellent on the HOX (Compared to VZ Gnex or Captivate at least!)

Charging it overnight, no problem.

I charge it when the battery symbol turns yellow and take it off the charger when I need/want to do something. I don't pay attention to the percentage, battery life is that good for me.

[ceowin]

I use my phone for the whole day until it pretty much only has 15 to 25% battery left. I turn off my phone when I sleep and charge it to full when I wake up. Usually I can reach 100 in about two hours before heading off to class.

Why not just charge it when you are asleep, and leave it on?

Run the ringer down to the bottom if you don't want people calling you at night.

Modern phones are designed to be always on, and can sit on the charger with no harm for months.

The only time I ever turn my phone off is when the Cabin Crew tells me to.

not sure that's a good idea, li-ion battery had better longevity when not staying at full charge all the time. it also should not be discharged too deep all the time .

But manufacturers KNOW that, so they set the max charge limit conservativly.

It stops charging, and does NOT trickle charge when still on the charger. That's why you can sometimes take it off the charger in the morning and immediately look at the charge percentage and find that it's down 7% or so.

Every phone manufacturer these days say leaving it on the charger won't shorten its life.

here is the data suggesting its better to charge to 90%, instead of 100%, and its better to charge before it go down to 10%.

[loraque]

What Icebike is saying though, is that when your phone tells you it is at 100%, HTC actually told it to stop at 95% and report 100%. When the battery shuts down at 0%, it is probably actually at 20% too. The manufacturers take care of it for you, so you don't have to.

I understand what he was saying, and I agree the manufacturers offer a lot of pre-configured protections already.

But if you install current widget and check the actually voltage when battery charged to 100%, its well above 4.1v. The protection offered by the manufacturers is good to have, but there are ways to improve the longevity on top of what manufacturers offered. Namely, partial charging, e.g., to ~90%, and charging often, e.g., before it goes below 10-20%.

Charge it as you wish, don't listen to people who say giving boost charges damages the battery - that's utter rubbish.

This was only the case on much older devices, they are not made or tested this way anymore.

These battery's are tested by cycles.

A 50-75% boost charge is 1/4 cycle, and regardless of this boost charge, they operate on 'cycles'

Only when a certain cycle amount is reached, does the battery start to deteriorate.

What Chrisjcks said.

But don't confuse boost charging with bump charging.

Boost is simply charging when you get a chance.

Bump is tricking the charge controller into over charging the battery in the hopes of getting a few more minutes out of the phone. It is harmful to the battery.

Bump charging is charging to full, take it off the charger, wait maybe a minute, then pop it back on the charger. It works with some devices by tricking the charger into overcharging beyond what the manufacturer specified as the max charge.


Boost is good, bump is bad.

Boost is actually the best way to manage your battery, after draining it completely ONCE when new to calibrate the charge controller.

This is where the Battery Swappers have it all wrong. They run their phone till its almost dead then swap in a new battery. Their charge controllers are always confused, and their dead batteries sit in their pocket till they get around to charging them. Bad for the battery in both ways. Then they put the phone on the charger and charge both of them to full. Worse, they buy an external charger that is not matched to the battery, and actually damages the battery.

An external battery makes so much more sense. You can boost charge any time you have a few minutes, (don't try to convince anyone you are on the phone for 8 hours straight), even when its in your pocket.

[clevin]

if you read the article linked, you will notice that its not about what is a charging cycle, its about partial charge enables more cycles before losing battery capacity.

nobody here is confusing about what is a charging cycle, we know from 50-75 is only 1/4 of a cycle. the discussion is really about high voltage and high DoD are not good for battery longevity.

[hart1233]

when charging my phone i usually unplug it as soon as it completes unless it is overnight and im asleep, i have never had problems with my battery by doing so, and i also never let it drain completely which i heard actually hurts battery

[erwaso]

I don't know why this is argued so much. everyone has their own way of doing things. but its a fact that charging every night from 0% or 80% doesn't hurt the battery over the course of 2 years at least. I get new phones every 18 month's so I don't know what happens after that lol.

[beck_is_back]

I'm charging mine every night, don't pay any attention to the level of charge when connecting to mains.

[Chema Martin]

I have done tons of trial and error and have found a surprising yet unexpected behavior that is consistent every time I try it.

I usually charge regardless of the starting point (although I try to start before I drain my battery beyond 10%) all the way to 100%. The interesting bit is, if I unplug my phone right after the LED goes green or if I do it shortly after, my battery life on that charge is usually poor and inconsistent (sudden drops of 10-15% for no apparent reason while the phone is on stand by). However, if I allow more time, usually 1 to 2 hours after the charge completed, I get much better battery life. I can't explain it, I thought it was down to chance because I know theoretically there is no reason why such behavior would take place, but I have tested it many, many times and I always get the same behavior, so there must be something there.

Hope this helps, it's just what I use, but it works for me.

[icebike]

Green doesn't indicate full charge.
It indicates "full enough" charge.

Charging that last 5 to 10 percent has to be done very slowly due to the nature of li-poly battery chemistry. It takes way longer than any other similar segment of the charge cycle.

So rather than making you wait for every last percentage the charge controller indicates "good enough".

Most phones work that way.

That's interesting, but still does not explain why the experience is much more consistent on the longer charge. If it was down to just "good enough", I would get the same experience, only shorter, but it is not.

Anyways, thanks for the additional background.

[dylan808]

I just run my battery until it tells me to charge. Then charge it until it says 100%. Battery life does not seem to be any different than it was 6 months ago.
