Hey everyone
Just want to ask if anybody noticed the same as me regarding the charger of LG:
if I plug the charger and use the phone it heats up really fast and charging speed is slow. The heat slows down my 4X HD and the performance is sh*tty as hell.
I once forgot my charger an used one from my dad's Samsung and I noticed a incredible difference. No heating at all and it charges much faster (with LG over night ~ 8 hours sometimes not even fully loaded from 15%, with Samsung 4-5 hours full with YouTube use and other minor things).
When I use my phone while plugged with LG charger it often even drains some battery (2-3% in 20 mins discharge, then charge up to 5% in the same time and so on).
Have anybody got the same "problems" or has my charger maybe a hardware failure?
Greetings

Weird. My phone charges from 0%-80% in like 1 hour, then the last 20% tend to take while longer. But also if I "Overcharge" it (that is to say charge it for about 2 hours when it's still 100%) it feels like it has charged 110%. Cause it takes forever to go down to 99% but then it decreases faster.
This is with the included LG charger. If I use my samsung (which is like 500mah) it takes longer.
I don't experince any performance decrease when charging.

Are you on stock rom or on a custom rom? I'm on WerewolfJB and that's maybe why it heats up but the faster charging with the Samsung charger is really noticeable, especially when I use the phone, like I said.
Thanks for sharing your experience with it

I'm on a AOSP rom (Slimbean). But I do share your experience with heat, both on the phone and the charger itself. But I think it's due to the high currency.
Your charger could just be broken. LG charger's output current is rated at 1.2A which means that the battery should be charged from 0% to 100% in about 1 h 45 min. It could take longer if the charging current gets smaller when the battery is starting to get full.

wrong, "charger" is not current source
for topic: your charger is bad, replace it
I had an issue that CPU was always 760mhz while charging with zen+HYPER governors. RevoltJB+OP kernel 2.53.
Noticed that my raspberry charger(2A) was faster than LG stock charger. Also normal for me too that battery even decreases while using phone at charger.

there is maximum allowed current to charge phone. it is controlled by electronics inside the phone. if you are using charger that has bigger maximum current it is possible that phone battery is faster charged, but as i said, it depends on interior charging circle
Charging Current 101
To clarify the above responses:
The LG charger *should* be more than adequate to charge the handset, as that is what it was designed to do....
If you were to use a different charger, e.g. one from another phone or a shop bought replacement, then the maximum output current of the charger is an important factor: the lower the rating (in mA or A) the slower the charge and therefore the longer it will take. Using the phone whilst charging will also increase the charge time as you are using the battery whilst charging it (like filling the bath with the plug out), more so with apps that load the graphics processor (GPU) such as youtube or games as these are battery intense tasks.
The rate at which the battery charges is ultimately decided by the handset; most modern phones will fast-charge most of the way, then slow charge the last few % to avoid overheating and damaging the battery, so having a charger rated to, say, 2.4A (or 2400mA) does not mean the battery will charge twice as fast as one rated at 1.2A as the phone dictates how much current it needs.
That will either clear up a lot of questions or will mean nothing at all

Same. Charging here is very fast overall.
I have an old wall charger from my ipad 1, which is bigger, and charges real quick, I went from 10% to 55% in just 30 minutes.
Does this affect battery life? Should I not use this?
Recommendations are welcome.
Regards.
I believe the iPad chargers are like 2.1 amps. The Z3+ has Quick Charging which can charge with about 3 amps. It's completely safe. However some people are afraid the extra quick charging heats the battery more and therefore also wears it out quicker which likely is somewhat true but there is probably not an extreme difference.
Hi everyone, I'm new here with my Note 9 coming from a Galaxy S5. I have 2 questions.
I want to know firstly what (wired) charging do the majority of Galaxy Note 9 owners employ? Standard or fast charging? I am very weary of fast charging because of increased battery degradation.
My second question is this. I am assuming that fast charging increases battery degradation because of increased heat from the higher voltages. And yes I know that it is adaptive and gradually tapers off. I have run an experiment. I have installed a couple of battery temperature apps and charged through standard charging. Then I have put the phone on a solid piece of steel plate and charged through fast charging. The temperatures of the battery are identical. I have checked this a number of times. The steel plate even at room temperature is quite cold.
So does this mean that if I fast charge with the phone on a cold steel plate and the temperature is no higher than standard charging resting on a usual surface, that fast charging in this case causes no additional battery degradation?
Thanks.
Fast charging, most of the time
Fast wireless charging all the time. Even when it's in my car dock it wirelessly charges in that can be for 3-4 hours a day on and off depending on journey. Screw battery degradation I'll use the upgrade programme to upgrade next year.
Slow charging. I have the same concern as you hence I off the fast charging function. No diff to me since I charge my phone only at night when I am about to sleep. Do not require charging to be fast.

If you plan on keeping your Note 9 as long as you did your S5 then slow charge with wire and also try your best to charge from 40 -80%.

Samsung is claiming 95% battery charge capacity after 2 years (80% is normal). So there is little reason to hold charging to 40 -80% for the normal lifetime of a phone. And also LION batteries are never allowed to charge or discharge completely - it's hazardous. So Samsung is already limiting how much power the phone can draw or charge the battery. (So do electric car manufacturers)

A quote is worthless without a source, where did you hear Samsung state the phone would have 95% battery charge capacity after 2 years? Also I'm not sure you understand Li-ion batteries, they are allowed to be fully charged but not completely discharged, this is included in the mAh ratings. Also electric car manufacturers do infact recommend something similar to 40 - 80% charging, for example, Tesla by default do not charge 100%. Even Elon Musk recommends 30 - 80% charging: https://twitter.com/elonmusk/status/448466037441179649
I use slow charging. I believe it is quite fast even with slow charging.
If there is an option to choose whether you want fast and slow charging, note that fast one has some downsides.

Although I don't blindly trust what manufacturers claim, I did however test my wife's note 8 and used accubattery pro on her device from new. Unlike me, she would always topup her phone and also fast wireless charge. After a year prior to her trading her note 8 in for a note 9 I checked the health tab, I know it's not accurate however as a ballpark is stated her battery health was at 97% which isn't pretty bad for 12 months of usage. My note 8 was at 99% using the 40-80 rule approx 90 % of the time. If one was going to keep their device longer than two years I'd still recommend using the 40-80 method to prolong battery life. However most Inc myself upgrade yearly so it's all moot. I just do it (80-40) out of habit.

And while I'm thinking of it. Why don't you substantiate your quote??
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Poco F2 Pro (Redmi K30 Pro) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
With the supplied charger and cable the charging time is very impressive ("Turbo Charge") with a normal QC3.0 charger charge time is still very good but comparable to most other QC3.0 devices.
Something to note is the device does get noticeably warm when using the supplied charger in the "Turbo Charge" mode.
Takes about an hour for me with included charger.

yes i noticed it get warm to hot-ish
isn't that bad for the battery?

That's normal because you're not using it, if using while charging it will be hot as your running apps, tasks etc... at the same time. This will increase the heat as sensors will be running also.
Has anyone tried to use other cables that has the same turbo charge effect like the included cable? The included cable is too short, usually I use 2 meters long cable.
I have tried the baseus 5A 40W cable but it only support quick charging and not turbo.
I've tested charging wattage using original 33W charger and original USB cable via specialized USB tester, and I noticed it provides only 25W (about 9.6V/2.65A). It shows "Turbo Charge" indeed, but it's still only 75% efficient. Anyone care to explain this? Is this normal? I've read that only Zoom edition can be charged at 33W, so I expected non-Zoom edition will charge at least with 30W. I tried two other USB cables, and still only 25W. Later today I will try to charge it with Blitzwolf 30W PD charger and see how it goes with that one...
I haven't really tested charge speeds. So far the battery life has been exceptional and the main reason I opted for this phone without the high res screen and refresh rate, as see battery as more essential. I would much prefer charging at a slow speed to preserve battery life. A good app for this is AccuBattery. It measures how many mAh's being charged and discharged after each charge and keeps a graph. It will estimate battery health also.
Yeah I know about AccuBattery, I've been using it in the past. But a real physical tester device is always more precise. I do sw/hw development for a living so I know for a fact. Indeed, battery life is very good because optimized MIUI and pretty big battery, but it would be even better if charging speed was also up to the specs. Meanwhile I've tested charging speed using Blitzwolf 30W PD2.0 charger (K30Pro should support PD3.0 and be backward compatible), and situation is even worse - only about 15-16W at QC3.0 I believe. So no Turbo Charge was initiated. I mean 25W with original charger is still good, but I expected advertised charging speed. I'll do more tests when I catch some time.
Thats normal, because it don't charge all the time with 30W. Compare it with WARP Charge 30T it is faster. OnePlus 8 got 30W and 4300 mAh, F2 Pro is faster with bigger bettery but it's almost the same.
How old is your Blitzwolf charger?
I know it shouldn't charge @30W above 80-90%, but sure it should at 20-ish where I'm at about now. It's also not even cool to the touch, so there's no apparent reason to slow it to 25W. My Blitzwolf charger is about a year old, but I only used it couple of times, so it should be as good as new.

Batteries don't like heat but it is actively monitored and it will slow down charging when it crosses temperature threshold.
That's why I mentioned my phone is not even cool to the touch (let alone hot), so my case is not temperature related. I'll try to charge it while turned off, though it was pretty much in idle doing nothing when I did the test, ie. not stressed at all by any factor. All in all, I mean if everyone else gets 25W out of original charger, I won't bother anymore. Also, if it charges from 10-90% in around 1 hour, I won't waste any more time on this either, since it's good enough for me. I was just curious why it charges at 25W, when 30W (and 33W for Zoom edition) was advertised. Altough it wouldn't be the first time something was advertised at launch, and not achievable in real-case scenario.

Fun fact: phone doesn't charge when powered off?! That's a first. Is it just me, or am I getting too old? For the whole time I'm talking about my Redmi, not to confuse it with Poco, if that matters at all. Maybe Poco works differently.
On my Huawei device you also can not turn off an charge but this starts with Android 10.
takes about 1 hour and 20 minutes for me, I think the high temperature here, summer season, is the reason for this slow charging speed.
From 20-100% in about an hour. Few minutes less actually. Battery is big, that's all ok.
F2 turn off and are dead with 0% (can't turn on). Timer 60 min. and after 60 min. I got 96% with original charger. The phone don't turn on, like it always do.
@Burs a friend told me "on my Anker charger I only can use PD over the third usb port, with the type c port it will charge over QC 3.0 and not over PD" maybe thats why you get ~16W?
When my Redmi was turned off completey, it was hooked up to my USB tester for about a minute. I doubt it would trigger after some minutes, and only then start charging. For the whole time it was connected, I was getting 5V / 0.015A readings on the display. That's pretty much USB tester drawing the power from the phone battery, not the charger! So that would mean charging was completely disabled making the phone behave as a power bank lol. Weird enough, right?
My Blitzwolf charger has only two ports. One PD2.0 (USB-C) and one QC3.0 (USB-A). I've tried three sets of USB cables (one even 5A) on both ports, and best I could get out of it was about 15W. I think I'll have to order another one with PD3.0 and Turbo Charge compatibility.
Heh I'm planning on just using my old 1A slow chargers because they're dotted around the house and work, will probably not even plug fast charger in. Magnetic cables are just so convenient.
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.
You can further go ahead and follow this guide from @spiral5 as well:
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.

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.

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.

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.

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
