Battery saving tips

Before we get an update (well if it will sort the problem...) I wonder if we could collect the best tricks and tips how to save battery life on Desire? Some of you have experience of apps and widgets that drain the battery fast, then we have the usual (turn of 3g, wifi, avoid white backgrounds etc).
What you think? Lets share what we found out!

- Turn off any auto-update for anything unless you really (really) need them
- Even if you really (REALLY) need auto-update, set auto-update period to longer interval (why do you want to get weather update every hour? just an example)
- Again, review your auto-update apps/widgets!!!
- Turn off GPS. Turn this on only when you are going to use sat nav app
- Turn off Wi-Fi. It is obvious, turn it on when needed and dont forget to turn off!
- Turn off Bluetooth, unless you want to use it (headphone???)
- Don't use task killer of any kind unless you really (REALLY) know what you are doing. Let Android OS take care of killing those inactive apps, Android is designed for this.
- Set your screen brightness as low as possible your eyes could use. Full brightness is really not necessary unless you want to show off to iPhone users
- Limit your home screen widgets, think if you really want to use to have "quick look". Otherwise you can just put icon shortcut, one click and there you go!
- Choose AMOLED friendly apps. Meaning, avoid any white or extreme bright UI / background colors. For example: The XDA Android app created by Tapatalk is AMOLED friendly compared to browsing via web, because it uses black color background. Find apps that you can customize the color
- Choose AMOLED friendly themes. I would replace the default HTC big clock that uses white color with other that uses black color.
That's for now

The first charge is important for the battery and your device too. The battery has to be charged long time, 12-16 hours first time to use all the chemicals it has. Some says that the polymer batteries don't need the first big charge but specialist's says it's good practise to do it with the LiPoly batteries too.
Note: it's best practise to wait until the battery reaches it's critical level (around 5%) before you start the first big charge. The first charge also calibrates your devices power meter.

Is this really really true? I hopefully will be getting a new Desire tomorrow (for exchange) and when I received my previous one, I didn't drain the battery and then charge for 12 hours. I would not mind doing it if it really improves the battery life but I've seen conflicting articles/opinions about this whole 12 hours charge thing

From HTC FAQ
http://www.htc.com/www/faqs.aspx?p_id=312&cat=80&id=127114
When I first receive my phone, do I need to charge the battery?
Your phone ships with a partially charged battery so it's suggested you charge your battery fully before first use. The battery is fully charged when the notification LED turns green.
It is recommended to charge the battery for 8 hours the first time to ensure that the battery has had time to recharge.
Note: It is recommended that you only use the charger and cable provided in the box your phone was shipped in.

Thanks for that although if I remember correctly on the Desire quick quide it says I need to charge it for 3 hours for the first time. Regardless, it insinuates that I shouldn't drain the battery before the first charge

Please try and read about how a li-ion battery works.
NiCd and NiMH need longer (and slow) initial charge(s). Because indeed the battery still needs to form. Usually 5 charges, but cheap ones reach max capacity after eg 15 charges.
This is NOT the case for li-ion batteries. They have max capacity as soon as they roll out of the factory. And they start degrading from that point.
Keeping the Desire charged longer has no use. Because as soon as the battery is full, the internal chip will cut off the charge. So you can just as well plug out your charger.
There are so many voodoo stories about batteries, even from manufacturers. Probably because each battery chemistry need different handling. Whereas li-ion batteries are actually much more easy. They don't last too long though :/

updates
Every now and then you get a notification of available updates to apps... anyone knows how this works and if it does drain the battery? Is there a way to turnthe update check off?

Can you try this:

Battery calibration app

Could someone please develop a good app that would enable the battery to be drained as much as possible and to charge slower so we could all properly calibrate our batteries?

Do we really need this since it's a Li-ion battery? I know Ni-Mh and Ni-Cad has memory effect, but not on the Li-Ion battery.

I was just wondering the same thing today....simply because there seems to be several different methods to do it. Some say charge 8 hours, turn off, charge and hour, unplug, turn on charge 10 minutes. Then other methods say to do something different....be nice to have an app to walk you through different methods so you know step by step your doing it right

I calibrated mine last night and I'm going to get about 18 hours if not more from it....before yesterday I was getting 9.
The ONLY other different I did was make some profiles on CPU but I cant imagine it would make that much of a difference. I bet its a mix of both

That is to funny I was just saying to my wife the other day that I should make one of these programs seeing that there are none already. I hate having to manually kill my battery every night before I charge it again.
Is it needed? It depends on your school of thought, some say yes, some say no. All I know is that on the few devices I have had in the past, if I constantly plug them in to "top them off" then the battery never ends up lasting very long after a few months of doing that. So I am a believer in killing the battery before charging on devices like these.
So the bottom line is if there is a desire for this, I may try to put an app together for it, as I know myself I am interested I just didn't think many others would be.

All the battery calibration tools, are basically deleting the file... right?
Is it that hard to boot into recovery and wipe battery stats?

I think the second part has to do with hardware. The phones hardware just doesn't have trickle charge implemented and instead lets it drop back down to 90% then starts charging it again.
As for the second part, it came on our phones, even has a default widget. 4G

Um... actually that is (by most accounts) bad for Li-Ion. You want to AVOID completely draining them. All of this stuff is more art than science, but I have way more often heard that completely draining LI batteries is bad. What kills them is the number of cycles they have been through (like -25 +25, -25 +25, -50 +50 would be a full cycle).
You do however want to give them a full up down cycle once in a while (maybe every 1-3 months) for calibration.
Then again, as I said, it is more art than science, and I have heard your method as being better, but the not draining argument seems to be the vast majority.
I'll try to do a little look-see and update this or repost if I find any stronger evidence.

the thing about my phone and battery that ALWAYS baffled me was i would plug it in at night be it at 10% or 22 i would leave plugged in while slept i would wake up unplug and look at battery percentage and it would be like 95.....no other phone has even unplugged and dropped 5 percent by doing nothing????

turn your brightness to 100% and change it so that it never turns off; use wifi tether and play a 720p movie at the same time; oc your kernel to it's highest stable frequency. it'll drain pretty quickly.

I know I might get flamed for this....
Apple suggests, with their laptops, to once a month or so, run the battery completely down. Then let the battery cool down for a little bit. Then give it a full, uninterrupted, overnight charge. I forget if they said to repeat this a second time, then you're good.
This is all from memory of me reading this a couple years ago or so, so our might not be verbatim. Their laptops use lithium ion technology...
(and they used to blow up and melt down too!) Lol!

That's because the phone stops charging when it reaches 100%, and runs off of battery probably until it reaches in the low 90s, then charges again. You won't ever notice this because the light will always be green. However, you'll notice that unplugging it a few moments after it turns green, the battery will stay anywhere from 100%-98% for a while. At least on my phone it does.

Is there any way to make this program "auto run" during sleep so it can do everything it needs to do during the night charge (similar to quickpull for blackberry)

I am by no means an expert so if you find any reliable info on this and can link us to read, I would love to learn more. All I know is that it is commonly said to drain rechargeable batteries and that I have seen that topping them off very often does lead to battery life degradation.

There is no need to fully drain the battery. Its purpose in calibration is to configure the software that is correlating voltage to percentage charged. That's all. Regarding the old Apple advice, that is doing the same thing. It will not affect the hardware.
Now, what WILL affect the hardware is charging itself. Every charge/discharge cycle will reduce the total capacity of the battery. This is why the EVO will not cycle on it's own until 10% discharged. It's improving the overall battery life by that restriction.
In short, you will save money overall by getting a higher capacity battery that you don't force to charge too often. Draining your battery does nothing but give you peace of mind and it only really needs recalibrating when it's total capacity has been reduced which isn't often. 3-6 months.

Yeah except that's not a good idea, it will kill the weak cells.

I understand. Still think it would be useful if it would do the "juice until LED changes" method while sleeping though

I'm interested!

Btw - what are the charging calibrations people are using? Are you seeing one working better than another?

Im a noob, so take what I say worth a grain of salt but yesterday I did the standard method where you fully charge...turn off...plug back in until led changes green and do it a few times.
I went from 9 hours to 17 hours with no other changes except a few profiles in setCPU.
I did this just last night so my results are fresh.

A few SetCPU profiles is all it takes to see a dramatic increase in battery life, especially while screen off. If you disable it I bet whatever gain you think was from 'calibrating' it disappears.

HTC One Battery Extender Case?

So the battery life absolutely sucks on my One. If I start using it at 8am its dead by 5 pm. And that's just normal usage like surfing the web over WiFi, playing games (candy crush, dots, angry birds space,) maybe watching a few short videos over WiFi and the occasional text message. I have a battery saver app and I can see that it helps but I guess there's only so much it can do,Z so I want to get one of those cases that has an external battery built in. I have a few questions.
1. Does anyone here use one of these? Please give your input.
2. What's the best one? I've done a little research and found that the i-Blason and Mophie ones seem to be most popular. They're both a bit pricey.
3. How do they work? Does the phone just start directly using the external power after you switch it on, or does it just charge the internal battery?
4. Can these things have any kind of adverse effects on the internal battery from odd charging voltage or anything like that?
5. Do they actually extend your battery time as advertised? I'd be happy with getting two full days out of a single charge and some of these things are advertised as extending it by more that 1.5x. It seems like if the external battery is just charging the internal battery it would be a bit less efficient than if it were directly powering the phone. Does that make sense? It just seems like there couldn't possibly be a direct conversion of 2300 mAh from one battery to completely charge another 2300 mAh battery.
I hope that wasn't too confusing. Personally, I can't wait until lithium-sulfur batteries are in all our electronic devices (potentially 4x energy density.) Google it. Sounds promising.

1. I don't use these so I can't comment on this.
2. The iBlason and Mophie are the only ones available that I have ever seen. The Mophie being the higher quality (materials not necessarily battery life) of the two but also twice the price.
3. The phone will use the battery cases charge first then once that is drained use the phones internal battery. However if your phone battery isn't fully charged and you plug a charged case into it, it will charge the phone.
4. It's a good question and I'm not 100% sure. If you use it properly it shouldn't cause any major issues. Using it "properly" meaning your phone has full charge when it is paired with case so that the case isn't charging the phone. That being said, the damage is no different than someone constantly charging and discharging their phone in short bursts rather than using it until it's dead (or as close to possible) and then fully charging. The big thing to be aware of is that the damage caused is simply a reduced battery capacity and usually isn't big enough to notice during the life span of the phone (1 to 2 years).
5. Yes they do. Some of the claims may be a little higher than life experience, but nothing drastic. It litterally adds a second battery to your phone, so it IS going to extend the battery life quite noticeably.
One thing though, I have had my HTC One for a month or so now and have kept it stock, occassionally trying custom roms, but always going back. I have consistently been able to get over a full days use with WiFi always on, GPS always off, brightness always on auto, and I have exchange synced and set to push notifications. I am constantly checking email and texting for work as well as browsing the internet and Google Currents. I also have the power saver turned on. A full day use for me being from 8am to around 12am.
I think either something is wrong with your phone, you are playing too many games, or some setting or service is draining your battery. I would post your battery usage here for some to inspect. And it might be a good idea to uninstall the batter saver app, they usually don't make any huge dent on battery life that can't be done without the app, since most rely on a polling service that runs in the background and eat up battery life themselves. Just make sure your sync settings are reasonable (not every 5 minutes), turn off GPS and only turn it on when needed, don't turn on WiFi unless you need it, turn off 4G unless you need it (switch to CDMA only in mobile settings), enable eco mode (power saver that throttles CPU based on usage), and make sure brightness is set to auto or a medium to dim setting.

Mostly right. I'll toss out though that cases have different current outputs-- the mophie cases will output at a high enough rate to cause a phone to register as being on AC. the i-Blason case charges at about a third of that rate, meaning that it'll trickle charge your phone/reduce power consumption rate, but it won't outright charge unless you're not using it.

1. I've used one for about 2 days. I returned it. It works well and the Mophie definitely feels of high quality and feels great in hand. However it makes the sleek device very big and bulky.
2. I would recommend the Mophie purchased at your local corporate carrier store, reason being is that usually your carrier will offer a 1 yr warranty on a premium case like this. However if you break or it shows ridiculous wear and tear they wont. I cannot comment on I-Blason's warranty. Although I think the Mophie is perhaps more expensive. Some carrier offer discounts based on employer's of the account owner. So that might help get the case cheaper.
3. See comment below
4. Usually since they're molded directly to fit your device, most manufacturer's will accommodate the OEM's requirements. But the Mophie charges as fast as it would if you had plugged it into an AC charger.
5. This question is a bit more confusing for me to answer. All I can say is that if they advertise a 100% charge then that means they're matching the mAh capacity of the device. (Ex. phone model has a 2000mAh battery internal and the case advertises 100%, then that means the external battery is also rated at 2000mAh.) So in reality if you're expecting a complete 100% charge while your device is still on, then no, you may get from 1% up to 70-90% depending on how much you're using it while its charging.

This is not entirely true. Because the Mophie has an on/off switch. So if the case is set to off, it'll use the internal battery first, then you need to switch the battery case to on to begin charging the internal battery. It is entirely possible to use the phone till it completely shuts down when it run out of juice and the Mophie have a full charge.
It uses the same charger as the phone itself so the case never has to come off, however even if the switch is set to off it'll charge both items at the same time.

I was not aware they had an on off switch, that would change the way the phone handles the device and give you a bit of flexability in how you use it, which is good.

I wonder if it would use the case battery first if you turned it on when both are 100% charged. Everywhere I've read, people seem to use them to charge the phone after the battery gets low. It would be great if the phone would just draw power from the case until it dies and flip over to the phone battery. I feel like that would keep the phone battery more healthy by avoiding inconsistent charging. If you're constantly killing the phone battery and using the case to recharge to less than 100%, then killing it again... it just seems like that would be bad for the battery.
Thanks everyone for the input! Keep it coming!

Good question. My thoughts would be that the phone would only draw enough to keep topped off. So I guess if the switch is left to the on position the whole time you would get the desired effect of draining the external pack first. But I would guess that doing that would reduce the efficiency of the case somehow.
In the end whether your constantly killing and charging your battery no matter to 90% or 100% with the case or A.C. charger, doing it more often will kill your battery either way. Given lithium ion batteries are way more forgiving than the old cadmium based ones that built up a memory of sorts.

To keep the battery healthy in a phone, make sure you charge to 100% each time. You don't need to fully drain battery, it's actually healthier to go from 50% to 100% than 1% to 100%.

So if my phone only gets down to about 40% each night before I plug it in to charge all night I'm ok? In the back of my head I'm always wondering if I need to drain it all the way sometime.

You are fine, it's better to not drain the battery all the time. It lasts longer if there's charge left. You just have to make sure your fully charging to 100% and not charging only to 70% or something like that. This is how lithium batteries work in all devices, laptops etc...

And either way you wouldn't notice the loss in capacity until you at least 2-3 years out.

So I've been thinking about this a lot over the past few days and I have something else i want to throw out there...
If you have your phone plugged in to a charger while at full charge, you can use it all you want and it will never go below %100. Does this mean that it's completely drawing power from the charger, or is it still drawing power from the battery, which is just constantly being topped off? Because I know I can completely remove the battery from my laptop and as long as it's plugged in to the charger, it will continue to function just fine.
If the phone is drawing 100% power from the charger, doesn't that mean that it would do the same for one of these battery extender cases?
Like I said before, I think that would be a lot more efficient that just using the case to recharge your phone's battery after it gets low. This way you sort of cut out the middle man.

BTW... I found that there was a weather app that I think was constantly trying to access my location even though I have location services turned off. I now get a good 10 hours of battery life with moderate usage. Still want a battery extender case. 2 full days would be awesome.

HTC battery life DOES suck compared what it can do because you are not going to buy a phone like this if you wont chat/text/call/email/play games alot. Mine lasts 10-15hours (usualy 2.5-3hours screen time and NEVER more than 3) and thats annoyng because its ok if im just ordinary home-work-home rezime but if i need to go out of the city for lets day 2-3 days - im screwed and allways must think about charging.
I have overlooked everything nothing wrong with the phone - the battery is just too small.
i keep wifi ,gps and bt off if i dont need them but my phone ofcourse syncs everything (thats the point of a smartphone - to be connected!) and i play often also.

Nope its being topped off, phones are all about maximizing space in the phone, it would require more wiring for the motherboard to be able to draw power directly from the micro usb port as well as the battery. For example, my Samsung phones can be plugged in but if I take the battery out the phone turns off.

I got this one - all day w/o charging w very heavy usage. Traveling w/o signal - 2-3 days no charge. Makes the phone bigger and you can't see the gorgeousness of the phone, but it protects it all around and it lets those 4 cores and crazy display to do its job w/o dying on you fast.
This guy sells them for $20. Have seen them in other sites for $70-130. Same exact model.

1. I have the i-Blason black.
As a Case
Pros: Great volume controls, Black matches the black HTC One and the black earbud plug, kickstand, central USB plug.
Cons: Thick, Gets Warn when plugged in
3. There's a button that turns charging from the case on or off. Phone will be like it's externally charging.
4. The i-Blason is a lower current charging, so there's a warning that pops up. I think it's not harmful.
5. Extends, yes. But >1 day, no. Well, if you're not using the phone, yes, > 1day. What I do is I let it charge the phone when I'm not near a usb plug and it gets < 80%, then i let it trickle back to 100% in about an hour. It automatically stops charging the phone at 100%.

Learn how to manage your phone guys. Track down the offenders instead of buying these battery packs and other nonsense.

Is charging the battery constantly bad?

Hey everyone.
Just wanted to know if charging the tablet almost constantly is a bad thing. I use the tablet a lot every day, so when I'm at 60%, for example, I charge it again while I'm at lunch or doing something else, so that I can keep using the tablet later with full charge available again. I never let my tablet go down to 5%.
Is this bad for the battery in the long run?
Thanks.

Generally, it's best to not allow full cycle recharging...i.e. not fully charge or discharge, it's better for small charge cycles, like 40%<->90%

That's right. At least for what I know. It says the same on Apple's website about batteries. :good:

So then I guess I'm doing it right, correct?
I charge from 60% to 100% or from 50% to 100% again. Maybe I should do it only up to 90% then.

I only charge to 100% when I am going to be away from a charger for a long time, otherwise I stop at 90%-ish (my battery app announces when it is at 90% and there are kernels which will stop the charge at what you specify), as the links above state, charging to 100% all the time will shorten the lifetime of your battery, this may or may not matter to someone, for example, if you buy a new tablet every year, or you're well-off financially, then you're probably not too concerned with how many years your battery lasts, in which case charging to 100% a lot won't really matter much, since you'll likely own a newer tablet by time the battery does die.
In short, it's up to you and what you want to get out of your battery's lifetime.

I am using the good old 100% and then use until near 0%. I have found that this way the battery lasts longer.
As I am writing i have 43% battery with 5:40h screen time. I am using Greenify btw.

There are two kinds of battery life. These recommendations are for battery longevity. How long until the battery begins to lose the ability to fully charge.
The article at battery university explains how charging works, and the best way to charge batteries. What you are doing is the opposite of that way. If you think you are going to have your tablet longer than a year, it's worth taking the time to read the articles linked.
There is noting particularly wrong with full charges every time, but there are 'righter' ways to charge.

Is there any kind of battery forming on new nexus7?
I mean i bought nexus 7 and straight from box i rooted,unlocked and installed custom kernel which forbids battery 2 fully charge over 92%...
Should i revert to stock and firstly fully charge my tablet then go to custom kernel or i am good at it right now ? Tnx
ps. (my nexus 7 was on 38% when i put it out of box)

Based on what I've read, you'd gain no benefit by reverting to stock and charging to 100%, it MAY or may not effect the internal battery calibration, but it does not affect the lifetime or anything.
Also, these kernels usually have a way for you to change the % at which it stops, usually by cat'ing or changing some value that the kernel reads, you could just cat/echo/change 92% to 100%, and let it charge to 100%, then change it back. YMMV.

The worst thing you can do to lithium-ion batteries is let them discharge completely.
Not letting the lithium-ion batteries discharge more than 10% will increase the cycles by thousands we're talking going from 350 cycles to 4000.
So, ideally, you want to charge your batteries (of this type) after a 10% discharge but we all know that's impossible so the best thing you can do is to charge your tablet everytime you can. Even if it has much battery left.

I knew that allready but i didn't know that it is not good to charge battery to 100 till i came to nexus 7 forums I always charged all my devices to 100% and never had a problem with battery

You should charge to 100%, there is no problem with that.
On a perfect world you would want to charge everytime the battery hit 90%, this gives the best amount of charge cycles and life time.
However we all know that's not going to happen because the tablet is here to serve our needs and not the other way around so stick to charging it whenever you can.

Great Question!
First let me start off by saying to the person that started this thread that this was a really good question to ask!
Now if you are trying to get the most out of your battery then you could look into installing/flashing a custom kernel that could allow for undervolting which could in theory give your battery more life.
So you all are saying that the best thing to do is to charge up to 90% and never let it get down to less than 10%? Always start charging when the battery gets to like 40%?
One question i have for the Nexus 7 2013. Is it even possible to remove the battery for this tablet or does it void the warranty? Second has anyone purchased a spare battery (if possible) for their Nexus 7 2013? If you did could you post a link to where you got it and let us know how much you paid?...

There has been speculation in the franco thread that undervolting could actually hurt battery charge life, due to the CPU having to work harder due to having less voltage, not sure if that has any merit or not.
The reasoning behind the not charging above 90%, and not allowing full-cycle charges is outlined much better in the links I posted than I could do here, also I would be just regurgitating information that is already there for the most part.
40% is just a number I pulled out of air, the best practice is to keep the charge delta as small as possible. So, let's say we charge the device to 90%, it is better to charge it when it hits 80% than it is to wait till it hits 70%, because a smaller charge delta has occurred, so charge often, but if you want the lifetime of your battery to be maximized (lifetime as in the way ezas explained it, i.e. "(...)battery longevity. How long until the battery begins to lose the ability to fully charge"), than try to not charge it to 100%.
Also, it has to be said, heat also affects the battery longevity, that is why I also recommend not charging while a device is in its case. And not leaving it sit on a Qi charger for too long, some cause more heat than others, but heat is a battery's enemy.

It would no doubt void your warranty. As for battery replacements, I have not yet found one, I'm not saying there isn't one to be found, but I have yet to find it, I figure the reason is because they are not yet in demand since the tablet is relatively new and demands for replacement batteries would be too low, obviously and eventually this will change.

What I said was that, theorically, in a perfect world, you want to charge your tablet when it starts losing charge and ideally never let it get below 90%. This is almost impossible because we use our tablet and we don't want to constantly be charging it so ideally you want to charge it whenever you can.

Redmi Note 8 Pro not charging at 100% after less than a month of use

Hi, I'm currently experiencing some problems with my Redmi Note 8 Pro.
I've had my phone for less than a month, and it's starting to get issues with the battery.
The battery, whether I charge it with the original wall charger, or I use a computer to charge it, or o use an alternative wall charger (that is for slow charge), it can't get to 100%.
It gets stuck at 99% and says, full charge in 2 minutes, even though the 2 minutes have passed long time ago.
I haven't done a full battery drain, and I always try to use a slow charge charger.
I also haven't done a full cycle without using the phone, maybe that's the problem.
But I'm worried, and I need some help, because I got the phone (as I said) less than a month ago, I haven't even payed the first installment.
I'm still within the seller's warranty, but I need some advices to what can I do, because returning the phone to the seller, to make a change, is gonna cost me 15 to 20 days. And I don't have any other phone to use.
Please, if someone can give me some advice, or tell me what to do, it's completely welcome.
Thanks.
And by the way, I'm using the Global 128Gb version, if that helps.
Edit 29/01/2020: I did a full discharge, because I couldn't read the quotes earlier, and I didn't realize how big the problem could be. Now, the phone can't go over 79%.

I didn't expected this issue with my RN8P, but with other phones (cheap noname ones).
A discharge to around 5%, and a full charge without unplugging did the trick for me.

When I cannot tell if its some HW related problem with your phone or battery but I am really wondering why you want to do full charges (and/or discharges)? It is known to wear battery way faster. Li-on or Li-po batteries do not have memory effects and it is known to be best to always keep them charge for example between 15-20% and 80-85% trying to never get bellow or above.
This phone has a pretty big battery, that normally should be enough to bring you through a day of normal use (if it does not you may want to check your hungry apps running in the bg) but maybe you are an heavy gamer or use your phone for some heavy usage stuff?
Even then, it would be best to do 2 quick 15 to 50-60% in about 30 mins with QC2 (18W original Wall charger) rather than one unique full charge.
Looking at what you said with slow charging you probably know all of that already, but the faster you charge the battery, even if same %, the faster it will discharge. As odd as it is, remains factual.
I dont know if you ever used an external amperemeter or similar to check what kind of current was actually going through your battery while charging, but if you do you will notice the first % goes way faster to charge than the last few %. The chip dealing with the battery charge, charges slower and slower toward the end because it could damage the battery, when on the opposite it is rather safe to quick charge the % in the middle.
Also you may want to check your alternative 'slow wall charger' to make sure it provides you with a steady voltage current (V). If it is fluctuating too much, it may damage your battery.
If you want to do further research about the subject, there is a note on the RN8PRO Telegram group explaining how to calibrate your battery by deleting some system files (root needed as far as I remember) and having some charges/discharges steps. Personally I have not done it because it requires to go to 100% and 0% a few times, and depleting a Li-ion/Li-po battery completely can damage it irreversibly. They are not meant to be discharged fully period. Now battery should not be completely drained when OS takes the phone off, that said we never know for sure since we cannot change that setting unlike on our windows laptops, but I dont want to take the risk.
When you are stuck to 99% it kind of looks to be the OS not being able to know if the battery is fully charged or not. In that state of things, have you tried to turn off the device without unplugging to see if the off-mode charging screen (the small battery screen with % when you turn your phone off) also remains at 99% or gets to 100% at some point? Because maybe all you need is to restart the phone to make OS aware the battery is fully charged. Could be a SW known/unknown issue/bug to be fixed with future updates for all I know.
But again, I don't think you should fully charge and/or discharge (if you do) your phone when you can avoid it.
Just my 2 cents.
Hope this helps,
Regards,

Hi Muad.Dib,
Well, I wanted to do that full charge a/o discharge because I thought it would help with the issue (turns out, it didn't, it got worse as you said) but I didn't know the effects of this before, I always thought it wouldn't have any effect. I wish I could have read your reply before doing it (I was busy and couldn't read it).
The battery lasts for more than a day (or it did before), and I always try to keep it clean from battery draining apps, and I don't play games that much on the phone, less than an hour per day.
Do you recommend me to do those 2 charges to 60% in my state? (phone can't get over 79% now).
I haven't ever used an amperemeter because I don't have one, and neither I do know how to use one of those.
If you can lend me a hand and give me the link to join the Telegram Group, it would very helpful ??. But I don't want to root the phone yet, cause the seller's warranty stills intact.
And yes, I have tried it and the off-mode charging screen keeps showing me 99% (or kept, because now it keeps at 79%). And I also tried few restarts and it didn't fixed it. :c
And I'm sorry, I wish I could've avoided it, but I read your reply too late.
Thanks for trying to help me anyways.
PS. I will try to do a factory reset to see if the MIUI update has something to do with the issue (because the seller told me to do it, and I will do it, though I don't think it could solve the issue). Please, if you have any advice before I do it, you could help me a lot. ( I'll do it something around 11:00 AM in GMT -03:00)

Hey.
Very strange what is happening to you it's probably the first time I read about something like this.
Please note I am no battery expert either.
From own experience and friends, usually when you wear a battery (or it worn by itself after use or bad storage condition before being sold) it still goes up to 100% but does not retain original design capacity anymore. The usual behavior is like for example you still have like 30% left, and suddenly it drops to like 5% and you only have a few seconds to plug it in the charger.
When that's happens it is time to change battery.
In your case I really have no idea what could prevent HW/SW to reach 100%.

Oh those are easy to use as I meant some kind of small USB device that you plug in between your charger and your phone. They are cheap and you get them for like 10 bucks on Amazon. Readings might not be 100% accurate but they still give a decent idea as they display Voltage, Amperage and accumulated capacity/used current for device plugged.

As I said I am nothing like an expert or anything so I am unsure what I can do to help. However I did check the telegram group and I confirm you the battery calibration thing is a rooted thing.
To find that group it is pretty easy just search for Redmi Note 8 Pro OFFICIAL from telegram and join the group.
You find quite a few things there.

Normally nothing you could have done, could have damaged the battery this way. Depleting it completely could have shorten its life or damage its overall capacity, but by all means there is no way in just a month you could have damaged the battery to this point. So either the OS is not reading things right (what version of OS and phone do you have - which region is your rom?) or either sensors or battery have a problem.
Since you still are under warranty period I would definitely get it replaced. Maybe you got a faulty batch or something. This happens.

PS. I will try to do a factory reset to see if the MIUI update has something to do with the issue (because the seller told me to do it, and I will do it, though I don't think it could solve the issue). Please, if you have any advice before I do it, you could help me a lot. ( I'll do it something around 11:00 AM in GMT -03:00)

This definitely cannot hurt to try.
If that does not work return the phone.
Just to know, based on your flag I would assume you are in Chile but I may be wrong. If I am not mistaking it is summer there and probably is pretty hot. I wonder if 'too hot' could damage the battery.
Hope this helps.
