Hello everyone, I would like to ask for your kind help with this problem.
My Poco X3 PRO has a problem with its battery, when I see with No Gravity Kernel the battery data, when I flash the fastboot ROM it indicates 100% capacity and its battery has a long duration but after charging the device 5 times its Low capacity between 93% to 90%, specifically 4793 Mah, this reduces my battery life and it would be great if you help me to calibrate the battery and not end up causing the same error, best regards
No kernel can help with that. They just have different ways of displaying battery capacity.
Lost capacity on a battery is lost capacity, since the battery degrades a bit from regular use and charging. And using fast charging degrades the battery faster than regular 10 Watt charging.
Don't be too fooled with battery, use your phone same as normal ones.

Hi there guys, im trying to calibrate my battery (Stock 1530) using battery calibrator. I have two questions.
1- is it better to discharge my battery then use Battery calibrator to calibrate it or turn off phone and charge over night and power on> recovery and remove Battery stats bin?
2- why my battery at times says 4215 and at times 4209 when its full? can someone describe the right battery volts value to me, thx!
1. i dont use battery calibrator, but charging overnight and wiping battery stats is the way to go.
2. there's no such thing as a "right" voltage. li-ion batteries never charge to their full design capacity. what you should look out for is the current. your battery is full when the current decreases until it settles on a low value. the charging will then stop and you'll notice the current goes to negative.
I have Meizu m2 notes and a problem with charging the battery. I use stock Flyme and the battery does not show consumption charging diagram. There is no display of how much it was spent on screen off / on. What matters is that it shows charging, but it does not charge at all, does not increase the percentage. Or full, but very slow or I have to shut it off with full. I can not figure out what the problem is, what do you think can be a problem for the problem?
Hi Guys,
What is the best practice to charge our Note 20 to maintain good battery life?
I checked my charge cycle and it shows its 8 so far but I only have the phone for a few days now. And I guess 8 is not good as it says on Internet the battery life cycle is 400-500 charge cycles. So I want to avoid battery damage.
With this in mind:
1. Do we need to wait for phone to completely shut down because of battery and then recharge? Or its not good for the battery?
2. If the answer to previous question is "no" then when exactly we need to charge the battery to maintain good battery health? If, for example, the phone is on 30% and we recharge, how is it different from phone being on 80% and we recharge battery life-wise? And how this affects charge cycle and health?
3. Can we charge the phone as often as we want despite the battery level?
4. Can we leave the phone charged at all times (100%)
Just want to make sure I am using the most efficient method. Don't want my battery to die in a few months time.
Thanks!
Just change it whenever you want. No matter how you take care of the battery. With today's battery technology, you need a replacement after 2 years.
Best practice is never run your phone or any battery powered device past 25%. I know it's easy to do since we are on our device pretty much all day. Reason for this is because when charging the battery it needs to have resistance to charge correctly. Less resistance the less charge is given there for weakening the battery life and quality. I charge mine every night no matter what. Ive been doing this with all my Samsung phones and never had any issues. And last its OK to run the ballery down once a month to clean out old or bad charge voltage left behind.
Best to charge between 30-80%
Li's love small frequent charges ie 40 to 65%
As the cell voltage climbs so does the damage; try to avoid going above 80%.
Charging battery below 80° F can cause LI plating which permanently degrades the cell; try to avoid. Never charge when below freezing.
Try to avoid going over 100° F
High temperatures and battery voltage cause the most damage.
Between 5-20% has the lowest power density of the voltage curve, try to avoid using that range.
If discharged to 5%, recharge within a few days. If the cell voltage drops too low it will be useless. Generally this would take 2 months or more but don't chance it.
Use the 25 watt brick to charge, enable fast charging.
So my 4a has been having fast battery drain since few months now. I remember it having very good battery life initially. However now it drains battery very fast.
This is also surprising since I keep brightness low due to me being sensitive to it.. and also keep the phone charged upto 80% capacity only as I read that it prolongs battery life.
One thing I could note is that the phone drains slower in the 80 - 100 % range if the phone gets fully charged occasionally.
Hence I have been suspecting the 'rapid' charging which is enabled by default on stock charger to be one cause.
Is there some way to enable slower charging like what happens in case of 'Adaptive charging' post 80% capacity? I hope that will lead to lesser wearing down of battery.
Don't use a compatible cable/charger and it'll change slowly. I don't think any PC I've connected to can do rapid charging, for example, and the cheap USB chargers I have definitely can't do it, only the one that came with the phone can do it.

It's more likely an app that drain your battery in background than your battery dying already. Quick charge and adaptive charge are made to not harm the battery.
Are you rooted? If yes, install Franco kernel manager app from playstore.
In first page you'll see your battery life estimation (from system) and clicking on live monitor go-to the processes tab.
Just like top cmd on Linux you'll see which process is active and how much cpu it use
For me as an exemple i realized that when I'm using YouTube music. The AdAway app goes crazy and drain my battery. And its something that's not shown on settings/battety tab.
Fast charging stresses the battery more than slow charging. That said I almost always fast charge. I expect 1-2 years of battery life on my N10+'s though.
Charging past 80% or discharging below 30% stresses the battery; Li's like frequent midrange power cycling.
Don't start charging below 72F, 82F or higher is best. High temp cut off is about 102F.
Never attempt to charge a battery colder than 40F!!!
Erratic fast charging is a sign of battery failure.
A rapid decline in capacity is another sign of a battery failure.
Any rear cover bulging ie battery swelling is a failure, replace asap.
Once a battery is below 80% of it's original capacity it's degraded and has reached the end of its service life, replace it.
Degraded Li's are more likely to fail which can easily destroy the phone.
If the phone is used heavily or is 2-3 years old, probably time to replace the battery. Just do it.
On most phones the cost is low.

Mine does rapid one only Thankfully connecting a usb to a socket board does non-rapid

Thanks for the response
Frankly don't have that much usage of my phone. Will give sometime to observing with non rapid charging. Will give this a try if that still persists.

Thanks for the response. That was insightful
UPDATE:
Started slow-er charging since few days now.. and I really feel that the battery performance has considerably improved
Also update to Android 12 since few days as well so not sure if that has a role to play though I don't think so

If it seems to work better... I don't see any difference on my N10+'s though. Run times are the same slow/fast charging.
Keep a close eye on it as erratic fast charging is a sign of battery failure... I have seen that
My battery drains quickly when reached 6%, and drops after a minute to 5%, few seconds to 4%, 3%, 2% 1% and the samsung logo appears just as soon as possible.
Also when full charged to 100%, it will drop to 97% just in few minutes!
hello, this is normal(i think) same situation with S21 and S21ultra i have, quick drop few% from 100% and under 7% also unpredictable drop to 0.

from iphone 12 pro max to this phone, and really feel its weird

battery management on both devices are different. for example I had an iphone 13 pro max and battery would stay at 100% for so much longer than the s22 ultra, but then the drain would happen a tad faster. Also the running apps play a role in draining after certain levels. powering up a device this type does take a lot of power. Did you try power saving options after reaching a certain power level?
Also not a good practice to allow the battery to get that low. Battery longevity will be compromised.

This is also important. and if for some reason you can't charge and you are getting to 15%, enable battery saving and if you get below 10 use Ultra battery saving.
some experts suggest it is a good measure to let the battery drain to 0 once or twice to get calibrated. It shows 5% but it might actually be a lot lower than that, hence the sharp drop to 0. It should in theory be better after "calibration". And of course, battery longevity will be compromised by anything you do to it, whether it's charging to 100% or draining to 0%. For calibration you do this once or twice.

They're not experts. Lithium-ion batteries do not require recalibrating. Discharging to 0 is extremely hard on them.
"One particularly persistent battery myth is that you need to occasionally fully discharge and recharge to erase “battery memory.” This couldn’t be more wrong for lithium-ion batteries. It’s a leftover myth from lead-acid cells, and it’s pretty undesirable to charge your modern smartphone in this way"
