Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Well, a little research :
Avoid fully discharging a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries, have a set number of charges in them.
I also just recharge whenever I think necessary.
i charge whenever i want

Hm, great thread..I charge my X8, when was 3% of battery..And always charge to 100%..
you should avoid letter a li-ion battery get below the 20% area as this damages the cells in the battery li-ion have no memory effect unlike ni-cad even ni-mh battery had no memory effect but they did need a big first charge
I Charge my battery, just before dying. :laugh:
i charging my x8 before it dies.
@Deftone and @ androidnerd2
our battery is lithium polymer not lithium ion.
so we can charge it anytime we want its life is not compromised.
and ya its true we should not use it till the end of its charge.
but our mobile takes care of it. it shuts down phone saving some charge in battery which is always needed otherwise battery wont even charge if voltage drops down to large extent..
Lithium batteries in general are better to be discharged as much as possible before charging.There are several rules for optimal charging like turning device off or not topping off the Ion based ones but in general dont charge them unless you know you ll need it and dont be afraid to let them dry before charging them again.There is no memory effect on Lithium batteries but there is a Life cycle that you can extend with less frequent charging.

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?
Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!
Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/
right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full
Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

Wouldn't heavy usage while its charging put too much heat on the battery? Which is worse for it then worrying about charge cycles?

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.
I plug mine into a wall charger or my laptop...
At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.
i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.
Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.

THROW YOUR 120W CHARGER AWAY.
Get a charger for around 65W.
Get a decently good brand. ( I'm using Anker, 65W Mi Charger is also good. )
Anything below 30W would be too slow to charge your phone. Not really practical.
Personally tested a 10W charger, did not work out for me as it doesn't give me the same battery performance.
In my opinion, Xiaomi played us on this one. The 120W charger is a marketing gimmick. I don't think it charges the phone to 100% even though it shows 100%. Either that, or it messes with the battery calibration. As soon as I charge with a 65W charger, the battery goes back to performing properly. By that I mean, lasts me the entire day, and I still have 35-40% remaining the next day on medium usage like maps, streaming. On heavy usage, it still gives me great battery.
I'm 100% sure, you will notice the difference if you switch away from 120W charger as it will drastically extend the battery.
If you have already experienced the difference or made the switch, please do share your experience. On the stock xiaomi charger provided with the phone, the battery life is really terrible, the same usage gets me barely to the end of the day.
If you're still not satisfied by the drastic difference made by the charger only.

How to increase the battery life of the Xiaomi 11T / T Pro
Hello guys, I want to tell you about the adjustments that I have made to my Xiaomi 11T Pro and that have improved battery consumption, keeping the refresh rate of the screen at 120Hz. I would appreciate if you could tell me how it went...
forum.xda-developers.com
It will be simply because it is a fast charger, incredibly fast, and you can't completely charge lithium batteries fast, there is always a slow end stage that will take an hour or more regardless of how many watts the charger is. The last top off stage, or saturation stage on lithium cells needs by definition to take time and will charge at a lower current and it has to be slower.
They are showing 100% on fast charging, but that's only the bulk charge capacity with a lot of the saturation stage not done, so you don't get full capacity. The 100% indicator is saying you've charged as much as you can fast, but it might only be 70% actually full. If it is left on the charger, it will likely wait until the temperature has dropped then continue for an hour or so completing the saturation charge, all while still indicating charging is complete, but if you remove it from the charger the moment it hits 100%, then it's not the same 100% you'd get by leaving for a couple of hours.
If they indicated 100% correctly as being as charged as it can be, it will take 20 minutes on fast charge plus an hour or two for the saturation stage to be done, so doesn't quite sell as well!
Xiaomi are cheating somewhat by saying 0 to 100% in x time on fast charge, as the definition of 100% when fast charging is changed.
Personally I just charge over night at 5 watt, better for the battery and you get full capacity.

Great insight, they should have mentioned it in a different way instead of saying it's 100% charged. But then that ain't gonna earn them any bucks.
Are you getting a good battery life on 5W? As when i was using the 10W charger and use the phone at the same time it would take forever to charge. And the battery sot wasn't as good as well compared to 65W sot for similar usage.
I also use 10w (5v 2A) and can get for about 8h of sot, charging time is in my case takes about 2:20h from 17-100%Its not that bad, and i prefere slow charging time anyway, i only use 120w when in hurry

If you are using the phone at the same time as charging, you are of course using a chunk of that 5 watts to power the phone, so whilst your battery may not be discharging, there isn't much left over to charge it up.
I always charge overnight as I easily get a day if not a few days from a single charge as I'm not using it much currently as working from home, but if you need to top up during the day whilst still perhaps using it, you would need a charger with a bit more wattage.
Also note that whilst it may say 100% charged, that could represent anywhere from say 95% to 100% actual charge. This is because lithium cells can not be trickle charged, so when charging it will get to being a full capacity, then charging stops, the battery is allowed to discharge several percent before automatically being topped up again, and the cycle continues. So depending on where in that cycle you take the phone of charge, you might be really at 100%, but could equally be at 95%. Because people would complain if the true charge status was shown, i.e. people leave the phone on charge all night and its still only showing 95% in the morning simply because it's on the discharge stage of the discharge/top up cycle when they look at it, they would complain, so 100% is shown from say anywhere between 95% and 100% of real charge state. This applies to all devices. It is why sometimes you take your phone of charge at 100% and it seems to stay at 100% for some time, and other times it starts going down soon after you've unplug it from the charger. Google on their Pixels have an adaptive battery setting and use the alarm clock you've set to know when you are getting up, so they make sure they time that cycle so that you get the phone at a real 100% capacity.
Good thread fellas. Yeah 120w it's just a thing you should use when there's not another option or your in a real rush. And by using it your battery calibration might get confused.
It's as the OP mentioned, with 120w you can feel that your battery life is shorter than charging with lower wattages.
IMO and experience I calibrated my phone's battery (drained it to 0 let it turn off , leave it unattended for around 10 min, then charge it with a 10w while still turned off if possible. And leave it charging 1h more after it says 100%) and b ayer doing so my 11t pro finally became the 2-day phone it should have been from day one.
I personally prefer to charge mine with a 18w (1h20min) or a 22.5w (1h) during the day. 10w it's just for overnight, it's just to long 2h40min or more.
This might be the reason why Samsung nor Apple has not yet jump into bandwagon of 100w-ish charging. Even not to 65w. It just my hunch though. Still, 100w-ish charging might be life changing in certain situation. And if I recall correctly, the most ideal percentage to charge Li-On is around 80-ish, that might the actual percentage that we get if we charge to 100% with 100w-ish charger.
To be honest i tried 33w charger and 120w charger and battery performance for me is the same(4.5sot + 6 background yt music)
The thing is when u use 120W charger and battery go 100% you have to let it charge 5-10 min more because is not fully charged.
You can check with app called ampere(download from playstore)

Please try a 65W charger from xiaomi or anker, i guarantee you the difference. Sot also depends on the usage, but there will surely be a drastic increase in the battery capacity.
And i completely agree to your point on trickle charging. But unfortunately, it does not justify the 4 hrs sot difference im getting after charging my phone through different chargers. 65W gives me 8 hours, whereas 120W full charge gives me around 4 hours.
I feel xiaomi really just did this as a marketing gimmick and did a half hazard job at it.

If you are using the phone at the same time as charging, you are of course using a chunk of that 5 watts to power the phone, so whilst your battery may not be discharging, there isn't much left over to charge it up.
I always charge overnight as I easily get a day if not a few days from a single charge as I'm not using it much currently as working from home, but if you need to top up during the day whilst still perhaps using it, you would need a charger with a bit more wattage.
Also note that whilst it may say 100% charged, that could represent anywhere from say 95% to 100% actual charge. This is because lithium cells can not be trickle charged, so when charging it will get to being a full capacity, then charging stops, the battery is allowed to discharge several percent before automatically being topped up again, and the cycle continues.

Like i previously mentioned as well in the above post, trickle charging or that 5-10% of charge shouldnt make the difference im experiencing after switching chargers. 4 hours sot difference is no joke. Its literally half battery capacity.
I love the phone, but Xiaomi really messed around with us on this.

Unfortunately i don't have a 65w charger :/
I get 4.5 sot because i also use yt music for 6-7 hours in background + 5g all dhe time.
The problem i noticed is that when i use my phone after charging my battery gives me good sot (5 hour non stop gaming mlbb and still have 25% left). But if i charge at night and use the phone the next day the battery drain really fast (that's why i charge every morning before i leave home).
I'm not really happy with battery life to be honest but im really happy with charging speed
+ How you guys get sot 8hrs?. I never couldn't do that with my phones( old device k20 pro average 5hrs sot)

Even after switching away from 120W charger, if you're not seeing a drastic difference, then i recommend changing the chargers to something similar to what i own (anker) about 65W or a mi charger 65W (official). Because i personally experienced the huge battery life change, and i know this phone can give a 1.5 day battery life on medium usage. On heavy usage it lasts me easily the entire day (8hours sot easy). But usage may vary. And when i was using 120W charger, it was giving me 4hours sot, with the same usage. So i know, the phone has the capacity to do it.
Maybe it could be a non branded charger issue? I'm not sure. It should show quick charging when charging via the different charger as well that way you know its getting the juice it requires.
Rocking a Xiaomi 67W charger and so far not much difference. I'm using the phone out of the box, I am not switching back to 60hz since whats the point of buying it if you wont use 120hz. Lets see after a few more cycles.
EDIT: After using this 67W for 2 days now, battery life is the same. IT might not be the charger but going back to 60 Hz might be the reason some ppl had improved battery life. I will return back to 120W since I prefer the ultra fast charging while the phone stays cool at the same time (mine is at 40-41 degrees C and it charges around 20 minutes)
EDIT 2: Tried 60hz for a day, since I was out with family, it noticeably improved battery life even though I charged with the 120W adapter. Hopefully Xiaomi adds a dynamicswitch feature for us soon or a 90hz option

I tried using my phone on 120hz for a day or two, i get like an hour less compared to 60hz i find a major difference in battery even with 120hz enabled.
Not sure why. But if it works, it works.
Also just to clear my experience, i never use this phone on 120hz, even when i initially was using the 120w charger. It has always been set to 60hz for me, as i like to save battery wherever i can.
Update: Using accubattery, when my phone reached 100%, its still taking in current around 1500-2000mah range (around 10-15w) and its trickle charging the battery. The estimated capacity when reaching 100% is around 2200 mah(times 2 since our phone is a dual cell battery) then letting it trickle charge for a few minutes (an extra 10) made the capacity to 2550(which is around 5100 mah) and by doing so I am easily getting 6-7 hr sot on 120HZ. It may be a marketing trick to reach 100% in an instant but leave it plugged in for an extra 10 mins or so to get more screen on time.
quite great battery life

Don't trust the apps. Find some real volt meter.

Amazing!
MIUI 13 by any chance?
I am on miui 13 official, had heavy battery drain on miui12.5, disabled miui optimizations and now everything is good
Edit: apparently the program that handles battery changed after disabling miui optimizations, maybe it's a bug related issue
