I turn my phone on Airplane mode and unplug at night while I'm sleeping.
BUT! When at work and at home at other times, is it bad to leave it plugged in 100% of the time? (I.E. does it decrease total battery life over a few years to be constantly charging.)
Or is it better to unplug ASAP when it hits 100% and let it drop to 20-30% and recharge-unplug-recharge-unplug etc? (If so, how much of a difference would this make?)
And does it matter USB vs AC source? I know USB is half the amps, so this could have an effect too?
Honestly, the battery is going to deteriorate a bit either way over a year time span. It is probably best if you just replace the battery every year.

Doesn't matter. All you need to really be worried about is that you leave it on the charger long enough to get a true 100% charge, and you don't always put it on when at 80%, try and run it down from time to time to 10% type thing.
If you leave it on the charger 24/7 for a year, it will have no real effect on the battery that a year of use wouldn't do, and you might actually come out ahead since battery life times are based on charge cycles... when on charger, as you are asking about, there would be virtually no charge cycles.

Ooooh, interesting... Did not know that. I thought that leaving it charging was the worst case possible.
But let's be honest.
How long do you think you'll keep the phone?
I've never had one more than a year...

[Edit]: Well, my thinking is how BAD could this affect it. Like leaving it plugged in all the time = 50% battery capacity in 4 months type of thing. I guess that is not the case though eh?

To add to what pjcforpres said, I would suggest topping off the battery a couple times a day rather than always letting it run down to 20-30% (deep cycling) the battery. Deep cycling is worse for Li-ion batteries. It causes more heat for longer periods of time when you do charge. I would only discharge completely once every few months to keep the battery calibrated.
My personal habit is to top off frequently. If I'm at home, I'll let it charge to a true 100%, like pjc said, then take it off the charger and leave it off till it hits 75-80% and top it off again.
i can add to this discussion what i've learned about lithium-ion batterys
having it plugged in, while it is being taxed heavily (playing games) and already at 100% is a bad idea, then i discharges and recharges all over the time.
When it isn't full and you plug it in to top it off it shouldn't really do any harm, as long as you disconnect it when it's at 100%.
Emptying it completely also lowers overall capacity, 10% is a good threshold when to charge it.
When leaving it off to store it for a while, store it with around 70-75% in the battery. Storing it fully charged also lets capacity down.

I thought you WANTED to do this? I've heard calibrating it is running it until it turns OFF?

I respectfully disagree with creepinshadow's suggestions. I've read up on lithium ion batteries considerably in the last few years. 10% is not a good threshold to always charge your battery from... that's deep cycling and was great for nickel metal hydride, but isn't good for lithium ion. That said, there's no way for it not to get that low from time to time if you're away from your charger for extended periods and I'm sure it's not going to destroy your battery as fast as one might think.
As for storage, the I charge (or discharge) mine to 40-45% then pop it into the fridge for storage. Read that in a long article explaining how to treat li-ion batteries.
Like you said though, a full discharge for calibration is running it till it turns off then plugging it in while keeping it off until an hour or so after the light turns green.
I've heard many people say that leaving any device that has a battery plugged in won't harm it as long as you're consistant with the charge cycles. Like only plug in your phone when the battery life is >15% and charge it to 100% before unplugging it.
I get into trouble there, because (for instance) say I'm going to be going into the mall for a while and my battery is at 30% and it's going to take me 30 minutes to get the mall (I live in Northern Virginia, traffic is a *****, haha). I'll hook up my phone while I'm in the car just to have extra battery life while I'm away from a charger.
good question, i wanted to know the exact same thing so good to see someone else ask. got the answers i needed.
Look guys... the reality is that this discussion is really just academic. Take my recommendations, for example. It would be ideal if everyone could do what the study I read suggested, but it's not practicable to always top off the battery and not deep cycle the battery frequently. That being said, I'm sure the difference in battery life wouldn't be apparent for a very long time. I can't imagine phone and battery manufacturers haven't thought about this. So...while I've posted my "recommendations" based on that study... just enjoy your phones.
A new battery cost <$50 i'm sure... If you left your phone plugged in over night, every night for a year it probably won't hold a charge better than someone that unplugs in once it reaches 100%..
I personally would rather not deal with always worrying about over charging it and IF i still had the phone when the battery needs to be replaced, just replace it.
In the past 16 months i've had the Touch Pro, Palm Treo Pro, BB Bold & now the N1.. so i never have a phone long enough to even care lol.
I guess that's true. We can always replace the battery, unlike the Fruit people!
But I was just worried that the damage happened quickly. But I guess it's 9-12 months before seeing any real effects anyway.

Is there any difference in charging from USB vs AC adapter in terms of how it affects overall battery life?
Hi everyone, I need help finding out what is wrong with my Hero before I throw it out the window!!! I am having HORRIBLE battery life. I can unplug it and it's dead within 30 minutes at times. I am running the latest CyanogenMod 7 (GingerBread) 2.3 on the C Spire (Cellular South) network. I have recalibrate my battery to see if it would help but no change. I have also changed chargers but no change. I have checked to see if there is an app draining it but nothing is draining it no more then usual. This has been going on for weeks and when it started happening I had not changed anything on my phone. It just started happening out of the blue. Now I am having bigger problems out of it now that it is having trouble even getting a charge. For instance, when I plug it in sometimes it will charge and sometimes it won't. Sometimes it will start charging then stop. Like I said, I have changed chargers so I know it isn't a bad charger. Also the biggest problem now is that when I do get it to charge, it won't charge past 86%. It will stay there til I unplug it then it will drain down to 60% within 10-15 minutes, so now I can't even recalibrate the battery now to see if it will help. I thought well maybe my battery is bad but when I check the battery health in the settings it says Good. I do not have another battery to test it against. I also have freezing problems. Somethings it will freeze up and will not unfreeze. I will have to eventually take out the battery and reboot it. Then if I don't let it set for a little bit after I reboot it and I touch it during that time, then it will freeze again and I have to reboot it again. I really LOVE my phone, I have had it for a little over a year now! I have never had any problems like this out of it! PLEASE HELP ME!!! THIS PHONE IS DRIVING ME CRAZY NOW!!!! THANKS IN ADVANCE!!!
Anyone? PLEASE!
I just tried my sis in law's battery and no change. She has an HTC Hero also.
$5 on Amazon
Or
After a complete drain, Charge while its off overnight then turn on but into recovery so u can erase battery stats. Then reboot
Either way I'd still spend the $5 and u can probably find free shipping for black Friday.
U can also try a ROM called hero deck without adding anything. This ROM rocks on the battery life. Then for giggles put it in airplane mode with wifi off to see if it drains...
Good luck
V's CDMA Hero
It will not charge while it is off, that is another problem I'm having.
Sent from my HERO200 using XDA App
It is not the battery cause I put my battery in my sis in law's phone and she played on it forever and the battery did not drain and it also charged fast. I put her battery in my phone and it drained fast and would hardly charge, just like my battery does in my phone. So it is not a battery problem, it has something to do with my phone. BUT WHAT?!?!
Just to rule out if something didn't went wrong during flash of CM7. Try a different ROM and see if it same issue.
I did, I tried the ROM vidaljs suggested. Still draining my battery!
What charger ru using?
Is it different than ur sisters charger. That could be the problem.
I use a blackberry charger that has the same power output. So verify that the wires are not damaged and if it's not the hero charger then verify the proper power output.
V's CDMA Hero
I have used HTC charger, Blackberry charger, and Garmin GPS charger all with the some result, slow to no charge. The main problem is it draining too fast. Last night I unplugged my phone, which was on 40%, walked next door to my sis and bro in law's house, which is about 100 ft away, when I walked in their house it was on 11%!
Any suggestions?
Well if u visually look into the female plug on phone.. does it look damaged?
If not perhaps it may just be damaged in another way.

It looks fine. I had a Hero before this one and the charger port did break but this one looks ok!
Well I have kinda solved my problem! I have the cable to my charger pulled tight and taped to the side of it and it is charging now, but it take literally all day and all night for it to get a full charge! It still drains FAST when unplugged! This still does not explain the fast battery drain and how it still won't charge on other chargers that I know work! Oh well, C Spire has a Holiday Sale going and I can get a Samsung Galaxy S for FREE, plus my $65 replacement fee since I have only completed 20 months of my 24 months! So $65 for a Samsung Galaxy S sounds like a good deal to me!!! This might be one of my Christmas presents from my hubby! I might get him one too! Gonna miss my Hero though! Good times, good times!!!
Right on.... ur issue still bugs me when j think about... but a new phone compared to the hero is awesome. I got the nexus S 4g last week for free except for taxes and activation and it is awesome.
So the galaxy does sound like a great plan and gift
Good luck

okay guys, I need your help! I bought my moto x from verizon on wednesday. Since I bought it my battery has been acting REALLY strange. I brought it home and it had about 40 percent charged. When it got down to 23 percent it shot down to 3 percent in 2 minutes! I plugged it in right away and it shot back up to 23 percent. I didn't even think anything of it. I charged it up 100 percent. It was working perfect untill it got down to 23 percent. It shot back down to 3 percent in about 2 minutes once again! so I plugged it back in and then unplugged it at about 30 percent. it did the same thing once again so I just let it die completely. I charged it up to about 10 percent. It was working fine so I thought it fixed itself. So I charged it completely once again. then once it got low again it did the same thing. I let it died and charged it up to about 20 percent and it was working fine. I forgot to mention whenever it got down to 3 percent...it began to work normal again. Its very very very weird! So have any of you guys heard anything like this? Please help me! and P,S I have tried resetting the whole phone.
I know it would have been hard to hold back from using the Moto X straight away after buying it, but I'm guessing u didn't let the phone charger for a few hrs before powering it on for the first time hey? Maybe its a battery calibration issue? Short of rooting the phone and running software to recalibrate, I reckon u should just take it back to Verizon and try get it swapped over... Just in case it may be a faulty battery after all.

I think I should take it back and swamp it for another one. like the first 3 or 4 full charges of the phone it did it...but I just fully charged it this morning and its down to 15 percent. it seems like its working fine. I dont wanna think its working fine and then a couple of weeks down the road it does it again. then im out of the return dates. So I should just return it just in case?
My moto x also have same problem, don't know why, and I can't return it because I live outside USA, the problem just when I update the ota update

I have the opposite problem, from 85% it gets fully charged in two minutes. My battery seems to drain normally but I have significantly worse battery life since it started doing this. I'm down to about 17 hours with 2 hours of screen on, the first weekend I had it, it was over 24 hours with 3+ hours screen time.
I have the DE so I haven't returned it just yet due to the hassle.
Update...so i returned it back to verizon and got a new phone. DOES THE SAME EXACT THING. UGH. I noticed on my old moto x with each charge it was getting better and better. like the first charge it started at 20 percent and then drained. then last night before i returned it..it started at about 10 percent and drained quick. so maybe this is normal? and just see how it is with every charge?
That's sucks man. What are that chances! Are u doing the initial charge before use per the manual? I know it sounds trivial but I think it might be important to calibrate the battery?

every one tells me that how I should charge it completely before using it. I didnt do that with this device. I just used it right away. I never gave it any thought cause I never did it with my old devices. I talked to a person from motorola and they said because all the stuff you do right away it could mess up the phone and confuse the battery. They said with every day and every charge it should get better and better. does this sound possible? how would I calibrate it?

Good to get official confirmation that the initial charge is indeed important .. Thanks for letting us know!
I'm pretty sure that once u root the phone you can get an app to clear the battery stats / recalibrate.. Personally though, I would take this second one back to Vzw again and just get a new one to start again and maybe this time pls do the initial charge before going nuts... Don't worry, I know how hard it was to refrain from using it lol

Actually I found an app on the playstore to recalibrate without needing root. So I did charge it to 100 percent and calibrated it. Hopefully it works! I would return this one also but verizon is a joke. They said im only allowed one exchange even if its a bad phone. They said the second exchange will have to go through warranty which means they will send me a refurbished phone through the mail. which is complete bull**** if you ask me. I dont want a refurbished phone when I just got a new one. I think ill wait a few days to see if it fixes itself.

I've never been able to receive a new device and let it charge all the way up before using it. Today will be no different for me, I'm playing with my new Note 9 as soon as I take it out of the box. IMO, battery conditioning is not necessary. I've never worried about it, and I've never had problems with battery life.
Hello for battery calibration is recommanded to charge it at 5% to 100%
Just enjoy it. Mine came with 60 pc and charged at 15. Never done any ritual dance or calibration and never had a problem.
Got mine with 55% and used until it died. Like the others have said, I've never worried about when and how long I've charged a battery and never had issues.
There are tons of info on this online. General rule is you do not want to charge 100% nor run it down to 0%. This is bad for the battery. I just try to keep my phone away from 0 and 100. Usually at 40-70. Accubattery app is pretty helpful in this regard.

I agree. Except for the fact that science shows it's right. People are actually paid to do this research, unlike us posting on a message board with our opinions that make zero sense. Do with your phone as you like, obviously, but don't disregard the science out of hand. Most people don't care because they keep their phone for a year and dump it, if you want to preserve battery life and keep a phone for longer than a year it makes good sense to follow the science.

I would say this:
After you are done setting up the phone, erased cache in recovery and ready to play with it, do this first to avoid calibration issues...
1. Use the phone and let the battery get drained to zero and shut down automatically.
2. See if it turns on (without charging) by pressing the power on key. Probably it won't but if it does , use and let it drain till it shuts down.
3. Now charge it fully without switching the phone on.
4. Turn it on , plug the charger and charge it again for the remaining charge to fill.
5. Use the phone and don't charge in between at all. Let the battery get drained to zero and shut down.
6. Repeat steps 3, 4 and 5.
7. Plug the charger, switch it on and charge till 100%. It's calibrated now, I believe.
....
After this, DO NOT repeat this 100 to Zero and Zero to 100% charging 'coz it'll shorten the battery health and if you plan to use the phone for say above one year, 2 yrs etc. Now on, Do not let it go below say.. 20 % and above, say 70,80 %. Keep charging in the middle whenever you feel like. It'll keep the battery healthy and will last longer.
Some people are so damn stubborn. The researchers... nevermind.
I didn't want to let my phone die because my friend's note 8 bricked because of it. I trickle charged it and managed to get it to start again after an hour. But then he left it on and it bricked again. So I didn't want to risk it. I had a portable charger so I let it juice up while I was playing with it lol
Just use the damn phone. :laugh:
The other advice is to keep your phone cool when new as you're updating and transferring data etc batteries don't like heat.
Let it die, let it stay without electricity for 3-4 hours and charge it. Let it stay at %100 for 1 hour.
the legend says u should chatge it one u take it out of the box
don`t believe that.. i got my s7 edge and i didn`t charge it first time, i played with it until itvget 12% charge then i charged it to 100%
i didn`t get any problem with battery at all
With the announcement of the 1-year extended warranty, I went to go replace my battery today at ubreakifix. When I picked it up, the employee gave me the feeling they didn't actually work on my phone but billed Google for the work. Besides the fact that the things he said made me feel like they didn't actually work on it, I noticed when I picked it up the battery was within a few % of when I dropped it off. I'm trying to see if there's a way to check capacity or anything of that sort I can do to verify that my battery was or was not actually replaced.

Your SOT should noticably longer.
New batteries typically have around a 50% charge on them.

It was around 47% when I picked it up but I dropped it off at 53% which I thought was odd. That's good to know the range is correct for a new battery though. The guy was sketchy and made several comments that made me think he didn't actually touch it. I was hoping to check capacity or something to verify the change but I'll use it tomorrow and see how the battery life compares. If I'm still having battery issues, I just wanted to have concrete proof if I went back. He made a point to say "if it's still acting up then you'll just have to call Google and have the device replaced instead".

You can use AccuBattery to check estimated battery capacity. You'll have to go through a few charge cycles to get an accurate estimation.

I might give that a try as well. I heard that just estimates but I guess that's better than not having any idea at all. I'm doing the first full charge since I got it so I'll download AccuBattery and run it the next couple days. Thanks for the suggestion.

It's total battery capacity estimates are not accurate. If you had been using it before it's SOT/% history would be useful.
I use it track my battery usage % vs SOT to spot misbehavior.
It's charging time/% history is also useful for monitoring charging. Erratic fast charging is one of the signs of a battery failure.

It's accurate enough to give you an idea if you got a new battery or not.

It can be off quit a bit, 10% is typical.

It can also be pretty accurate, in my experience.

It's history is but the actual mAh measurement isn't.
With no calibrated reference of the voltage to mAh ratio it can only do so much. I believe it's measuring voltage drop and calculating current and mAh from that instead of voltage×current.
Whatever the reason(s) it's absolute battery capacity isn't accurate.
I maybe mistaken but even though some power controller chips have current sensing capabilities, Android doesn't use that readout or make it available to any apks.
An Android shortcoming.
A Developer here maybe could or has shed light on this before.
Edit: some brands/models can apparently:

No information on Samsung models that I could easily find.

Like I said, I have found it accurate enough in my experience. New phone is around 100% estimated capacity. Year later, 90% or so. Year later 85% or so. Done this with several phones.
Not here to debate or argue about it. If the OP doesn't want to use it, they don't have to.

That 10% is from the original OEM battery and the replacement. Android it's self lists it at 4100 when it should be 4300 new. Accubattery uses the Android figure unless you change that value.
He'll get a good enough idea if the phone last longer during usage. It should be a noticable improvement... and I hope it is.

The battery capacity for this phone is 3,700. Like I said, I'm not here to argue or debate it. You do what you want and the OP will do what they want. So please stop quoting me. Let it go...

Just reporting back that it was definitely changed. I charged it before bed and decided not to put it in the charger over night to see what happened. I woke up and it was still at 99%.
It's been off the charger since 11pm yesterday, it's 8pm now and I still have 16%.

Good deal
Guess the tech just has a guilty face

Another way to check is with this online tool https://bathist.ef.lc/ Battery Historian. Make sure to charge your phone to full keep on the charger for a bit longer even after 100% If you can do it with the phone powered off that's even better. Turn the device back on take a bug report and upload it to the site. Then look for the "Coulomb charge" value and mouse over it. It will show you how much the device charged in Mah say for example you see 3650 then you divide it by the battery capacity for our device which is 3700. This means your battery health/capacity would be about 98.6%.

Assuming that phone has accurate current sensing hardware and it's readout is available. All Androids report voltage relatively accurately... current not as much so.
