Does your phone stay warm after charging to 100% when still plugged in? - Xiaomi Poco F1 Questions & Answers

Basically, plug it in via USB and charge it while it's turned off (offline charging). It makes sense that it would get warm while the battery gets charged. However, I noticed that it stays noticably over ambient temperature when left plugged in after it's fully charged, even after hours. Not hot, but hand warm. No idea why it would still produce the heat in question, common knowlege says the regulating chips inside should completely stop any energy flow when it's full. Weird. No idea if that's normal, a software or a hardware issue.

Hi,
I noticed that last Friday when I changed my battery to Nohon. It was the first installation of the new battery, I used for an hour the phone and then I turned it off to charge it completely. (I don't usually turn off my device to charge it so I noticed this now)
I noticed the device was warm and stayed warm even after was finished at 100%. I thought was the battery, I unplugged from the charger and I checked the temp was 35c. Then I let it and I was checking regularly, the battery temp drop down to very normal temps. Afterwards when I charge it again but with device turned on I didn't noticed this warm which I felt when the device was turned off....so Idk. I haven't tried to charge it again while turned off.
I am on crDroid with NGK.
Btw, the Nohon battery is amazing, 17€ and my phone is like new 11-12h SOT

From Official Store of Nohon at AliExpress. It took around ~1.5-2months to come but worth it

Only on particularly hot days and that too while using the device. Indoors I use the device plugged in pretty much always but I limit charge to 60% to reduce the voltage stress. Otherwise when not in use even at 100% charge temps. are a non-issue.

That's great. Do update how it holds up after say 6 months to a year. It was very fortunate that for a few months last year Xiaomi India ran a promotional sale on replacement batteries in which F1 battery was marked down to just €12 equivalent as Aliexpress is banned here. I considered buying another battery but since they returned the original battery which despite it's 65% health was still good for 8+ hours SoT in A12 I decided against it. F1 will serve as my daily driver only till the end of this year so as a secondary device the replacement battery should last years.

Battery issues part 2

So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol

Battery charging cycle

I've had my Titan for nearly 5 months now. I am hoping Titan's battery isn't that crap as I think. However, since last 1 week what I've seen is my LED goes green to indicate that my phone is charged. It shows 100% in battery saver menu. However, if I restart my phone while it's plugged in the charger even after green LED, then after the reboot my battery is down to 89-91% mark. Either the battery calibration has gone wonky or the LED doesn't recognise the real battery levels.
It would really help if anyone who charges their phone during the coming week, could restart their phone while plugged in as soon as you see green LED and then see if anything changes in your battery stats?
I've noticed my phone does last an hour or two longer if I charge after this reboot till it's 100%. It could well be a placebo effect for me. But might help if others see the same too.

The calibration is a little wacked. Here is my example - i charge it for 5 hours and it says 100%... but it only lasts about 7 hours and i can tell throughout the day that it drains faster. If i charge it for 8 i get closer to 13 with heavy web and game use. At 5 hours it turns green also ... but it seems as though it still charges more when left plugged in longer.
Some apps also like wp7 news clips off about 1 to 2 percent battery everytime i run them. (it brings in feeds from 20 different websites (estimate, i didn't count) so it's worth it but i check it a lot.
Could be wrong but as far as im aware that over charge protection. Your phone shouldnt really be charged 100%. 90-95% should be the sweet spot. Generally when i first noticed that i used to restart the phone and charge it to 100% but my battery life actually got less than just letting the phone decide when its enough
My titan has recently been getting more and more life from the battery; upwards of two days. I turned off wifi and I got 4 days 4 hours, died just some hours ago (I don't game much, but I do listen to music).
I've been getting into the habit of charging it when it gets below 5%, not every night like I used to. So it'll be 30% at night sometimes, and it'll last me another day with light/average usage (as opposed to my previous mindset where anything below 50% is a no go).
It might not work to leave till last 5% especially for someone like me who travels a lot. Don't you fear at times that your phone might faint when you really want to use it? As soon as my phone goes in battery saver mode I plug it in. Maybe that 90% limit as a reason. Over riding it helped me but if I did not over ride the following cycle then my battery performance seemed awful! Very strange working indeed.

If I plan on using it AND I know I'm going out where there is potentially no USB to charge with, I bring my portable USB battey charger and/or one of my other phones. However, I don't mind not having a phone with me at all times, so if it dies, it dies. Still, I just got it to last 4 days, so if you don't watch videos or play games frequently, charging every three days is unheard of for a smartphone!
The battery's health relies on charging it properly, and I value keeping this up over having it charged when convenient for me. Battery saver kicks in at 20% I think, and with battery saver, you'll get almost another day with light usage, so charging when battery saver turns on is probably really hurting your battery.
I generally unplug my phone when I notice the LED turns green (even if I'm going to bed for the night I'll unplug it). I have never had such amazing battery life with any other phone, but I also have never taken such lengths to improve battery life either.
Why don't you pick up a brand new HTC Evo 3D battery off eBay or something and use that? Its a 1730mAh battery compared to Titans 1600mAh and works fine in the Titan.

Deep discharging a Li-Ion is worse for it than frequent charging. Temperature also is very important and I haven't noticed the battery get hot when sitting on the charger after the light turns green.

Hot device when charging.

As the title would suggest, my poor GS2 gets VERY hot when charging. Not all the time, but often.
If I charge from my PC's USB, it doesn't, but when I use a mains charger, it overheats.
When I finish my night shifts, my battery could be down to 20%, so when I go to bed, I plug in the phone, set it's alarm and pop it under my pillow, like I have done with every phone I've ever owned without issue. I wake up during the night and pull out the phone to check the time and almost leap out of bed because of how hot the device has become.
To make matters worse, it's discharged in battery power. This morning was the final straw, as when I checked the phone and it was red hot, it was also dead. I held down the power button and booted up the phone. It showed 15% battery left. I know people say that when it's charged, remove it from the charger, but it isn't practical. Besides, I've never had to do this on any other phone I've owned. This is unacceptable for me to rely on any more. Is this a common issue?
Or my fault because I have rooted the phone the tried custom roms/kernels/modems on it before?

1) change to a diff kernel and see for the issue.
2) well charging from 10~20% to full 100% will lead to heat up the phone than charging from 50~60% to full 100% , hence also check for the same and see

I should have mentioned. This happens on any Rom and I've tried 4 kernels and still the same issue. Only thing I haven't tried, is going back to Samsung stock rom. Going to try that today, see if that solves it and report back.
Like Samsung told my wife "when it gets hot dial *#*#4636#*#* and note the battery temp".
Is it still under warranty

Well the PC's USB output would be limited to .5 A whereas your wall charger could provide 2 A. This might just be normal IMO, although I can't say that my phone gets ridiculously hot during charging. As others mentioned, I would check the battery temp.
The issue is already in his post and the solution as well.
1) The S2 has the tendacy to get hot. Its all very compact and there are no internal ventilators so the S2 dissipates heat to the rest of its body.
2) There is a Power difference between the charger and a USB cable. The charger gets hotter since it delivers power directly of a higher voltage and slightly higher amps then a usb port.
Your issue comes from one sole thing. Your bed. beds have very poor heat dissipating abilities, in fact, it has none. Considering no fresh air is delivered to your device, because it is stored under your pillow. Not to mention your pillow, the rest of your bed stop heat from leaving and it builds up. Ontop of that your heavy head is resting on it, pressing the pillow tight around the device.
in short, it has no way to relieve the heat. There is a simple solution of a non technical matter. Don't put the darn device under your pillow.
(the same counts to people that use there laptops on there beds pillow or covers without a proper cooling matt, before wondering why the hell there device shut down all of a sudden.)
The problem is you put your phone under your pillow. I made this mistake a few weeks ago and the phone was too hot but no problem when i charge it somewhere not under the pillow
I agree, I should stop doign that. But one question, if that's the case and the getting hot is normal, then why did the battery drop from 100% to 8% while plugged in?
Your cooking the battery, thats why.
i'll admit i charge my phone and leave it ON the bed so air still circulates but it did used to get hot. Not sure if any changes i've made such to things kernel, ROM, modem or undervolting has caused my change in temps but my phone never feels warm anytime day or night weather its on charge or not where as my partners phone (stock sgs2) does get hot using the same charging habits as myself

For the AC charger this problem is known: if the charger is of poor quality it will generate too much 'noise' (ripple) which disturbs the electric field used by the touchscreen. However the original Samsung charger is of good quality and does not have this problem.
Experiencing these kind of problems when charging by a laptop USB port however is abnormal.
Interesting.
I bought an official Samsung charger off ebay, and it produces the same results. Much to my frustration.
Leaving it plugged in all night however was fine, I placed it on a shelf and the phone was actually cold when I woke up. I'm just worried the battery is ruined. It seems to drain quite quick.

Anyone had long charge times with their official huawei charger?

I was interested in seeing what my charge times were using the official charger and cable so using accubattery i checked the charge logs ranging from 10-40% to 100% and they were longer than what the guidelines stated. Phone did state that supercharging was active, had two thunderbolts on battery as well as the bubble animation (i wish this could stay on permanent )
When i bought the phone, charging from 20% to 100% took 1h 50m
and then in about a months time...
Charging from 10% to 100% took 2h 34m
Charging from 32% to 100% took 2h 11m
These were all with screen off, do not disturb turned on and wifi on. The charging time is not THAT big of a deal as i'm always charging it at night but i'd like to actually recieve the speeds that were promised. Using ampere i never saw the current surpassing 2000mah sub 10% (i don't expect it to supercharge as the battery is nearly getting to 100% in order to prolong the longevity of the battery) and they would fluctuate down to 600-700mah a lot of the time.
So i contacted huawei support and the advisor agreed that the charge times i told him were longer than they should be so i've sent my charger (along with the cable) for repair. It's currently at their repair centre so i've not had a diagnosis yet on what the problem is, it could be the phone having issues for all i know!
I wanted to know if anyone else has been keeping stats on their charge times and whether you are getting times similar to me or slower/faster, would be interested to hear!
Do you have the double lightning symbol? If not, turn off your charger for about a minute and try again?

Difficult to say if there's any hardware issues, the repair centre will find it if there is one though.
Your charging times do seem a little high but its also difficult to compare a new phone to one that's been in use for a while, as there will be more apps running and drawing power etc than on a clean phone. Over 90% charge the charging rate will drop as you said, but that's not the only thing to affect it, temperature has a big impact...hotter charges slower.
Measuring mAh on the phone is therefore only a guide and shouldn't be used to prove slow charging etc. (e.g. if I have my satnav app, bluetooth & mobile data all on, then even using my supercharger, the charging rate shown by the phone sometimes drops to under 400mAh and even into negative figures if the phone is hot)
0% to 100% should be about 90mins in perfect conditions, but I'd be surprised if anyone got regularly near that sort of timing.
Got my charger back 2 days ago and today i deliberatly ran my battery down to 9% to see how charging would go. For the first time since recieving my charger back i've gotten a steady 4000mah. 9% to 72% (+2400mah) took 55m which is much better than the 2hours+ it took last time to get a +2600mah charge before. So yeah, if you're noticing similar speeds, contact huawei and see if you can send it in!
Mine charges from 18% to 100% in just an hour and 10 minutes.

Question How critical is it to just charge to 80%

I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

Hehe yea, I guess they all show 102% then because I have that as well
I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

Turn it off then.

Accubattery just provides a guide. See here:
battery drain
Hello, I'm using a pixel 6 with two cards sim. When I go to sleep the phone is fully charged and internet/wifi is turned off. When i wake up i have 88% battery (I lose 1,5% per hour). In battery use i see Ims Service. I did a test and in...

I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore. This meant more cycling, and I could fully discharge/recharge it 3 or 4 times a day. Within 6 months the battery only lasted 5 minutes, it was stuffed. Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
Held out about 6 months on a permanent usb battery bank, was such a slog to wait until the Pixel 6 was released.
