Low Battery Capacity - 3700 mAH against 4000 specified for k20 pro - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I have done rigorous testing with accu battery and found that battery capacity is around 3700 mAH against 4000 mAH specified.
I am using phone from last 6 days. 13 charge sessions, total 463% charged for 17177 mAH.
Refer attached screenshot.
Would request other k20 pro users to test and post there results.

Exactly the same here. Looks like it is indeed a 3700mAh battery

Mine shows up about the same. I think it's just a reading error with accubattery.

No it's 4,000mAh

4000 mAH visible in screenshot is rated capacity
Install accubattery from Google play store to get real / actual capacity. This will also help you to optimise the battery.

Maib try charging overnight with 5v 1amp charger
(Ofc draining battery to 0%
And power on until it discharges completely - until it won't power on )
Then charge overnight with slow charger
Then check with accubattery and let me know results xD

In my opinion if the phone is new there is no need of procedure what you are asking to do. That is for calibration purpose. I had few brand new phones in the past and each devices shown 100% sometimes even 100+% so i think there is something wrong with the software or hardware which doesn't let it show accurate health estimation. Still curious what others accubattery health is showing.

No improvement in battery capacity after 10 day. It's still around 3700 mAH.

This is because you don't leave it to charge long enough. Leave it for few hours and see that will go way up from 3700 Mine does.

AccuBattery algorithm is not optimised for fast changing. Check with a usb pd tester for accurate readings.

Same here:crying:

@akki_007 that's what I am talking

Stop misleading people. Charge your phone properly to full before jumping to conclusions.

Wow, you are lucky, but you have completed just 0.6 cycle. Request to post results after few days. Mine is constant between 3715-3730 after 12 days / 22 sessions. Tried all the suggestions in the thread and used 3c app also. No improvement. There are atleast 4 persons in the thread reporting the same. I am eager to see what you get after few more charges.

That screenshot was from 1 charging session two days ago. The lack of a recent screenshot tells me you are back down to 3700 like the rest of us.

Well, you are wrong.

so far so good, it's been almost the end of the work day and it's still on 74%
i'm going to run it a few more days, before i give my recommendations
also i'll reset the counter tonight midnight, and let it run a whole normal daily cycle to see how long it can last without recharging.
then repeat the process with the stock 1500 mAh battery
but just for reference, the stock battery by this time of the day, is already way down to 50% or less
sorry shaky hands

I hope this has more juice than the stock ones... normally anything the same size usually doesn't run any longer... heres to hoping it does!
There's been a lot of testing of aftermarket batteries... and they usually hold 70-80% of what they claim, so I'll be really surprised if this battery lasts any longer than the stock Samsung one. If it does, then that's great, I might pick one up, but I'm very skeptical... maybe a placebo effect?
The only way to really test is to get a voltmeter or do some controlled testing like video playback looping.

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life.

http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
There is only one way to charge lithium-based batteries. The so-called 'miracle chargers', which claim to restore and prolong batteries, do not exist for lithium chemistries. Neither does super-fast charging apply. Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers "typical" charge technique.
Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.

New battery does not hold charge

New battery was drained and fully charged while the phone was off.
Now it drains to 15% after less then 12 hours of average use.
When charger is unplugged the battery imm goes down to 97%
what is the best way to improve the battery performance ?
Don't use it as much
Everything has a work in time, your phone needs to forget about old battery and dance with a new partner. Give it a chance...
Oh and search is a good thing. This phone isn't cutting edge anymore.

Reset battery stats
Sent from my unbrickable cappy *bam*
Did you get this battery from china?
It probably has like 800mah.
Is there any battery today that does not originate in China ?
It is marked "SAMSUNG G7 1500mah".
I already tried to calibrate the battery about a week ago using a market application that claims to perform a reset of the battery stats.
after the reset I drained the battery for 3 days and recharged while the phone was off every night (during those 3 days).
then for the first few days the battery actually held up nicely reaching 50-60% after 12 hours.
after a week or so it started to drain more rapidly reaching 15-20% in the evening.
It also fails to hold 100% when the charger is unplugged, going straight to 97%.
should I try another battery or is there a another way to calibrate the battery ?

Is there a way to identify a genuine non-fake G7 battery ?
That's how mine looks. My battery does seem to drain fast when I am actually using it. But, also when I'm not using it, it seems to keep at a steady battery level for a while. I guess it's a trade off. I also use Juice Defender which definitely helps.
I probably used juice defender for about 4 months. Then I tried running without it and found I got equal or better battery life.

Quick charger Killing My Battery

I have been using quick charger to charger my N6 since I got this phone in 12/2014. I had no problem until recently my phone will power off itself when its battery gets to 15%. Before, 15%of better life will lasts me another 15-30 mins. I charges 2-3 times a day using quick charger and I think it's killing the battery!!! Anyone had similar issue?

and what evidence do you have thst the quick charger is "killing the battery"? i mean wheres your proof? i think doesnt prove anything. your battery stats just need to ne recalibrated.
How do I recalibrate?
Dude... Your battery is almost 1 year old... It's normal for the battery to start going weird with normal use between a year and 18 months however, you charging the phone 2 to 3 times a day isn't great and is likely a cause for your issue... I charge mine once a day.
There is a thread somewhere here in The N6 forum to possibly fix your issue.

lol, no. thats a battery stat, and ive seen them much wierder than yours. that has no evidence that charging using the default supplied charger is destroying your battery. but.. it might show that you have an issue, just not the issue that you think it is.

I'm just trying to figure out what happened. I know you said about battery calibration; but why my phone dies at 30%? I think I might need a replacement!
Its a nexus 6 thing, the internal power supply hardware for this phone is cheap and "just enough" to power the phone. When the voltage on the battery drops from being drained the cpu shuts down as a fail safe, the 5.1 update "fixed" the issue by underclocking the cpu and gpu at 40% battery (iirc) and unplugging cores at <20%. Many custom kernels remove this for performance boosting but then some phones run into the power supply issues usually in the lower binned chips (ones with higher voltage tables). Age likely doesn't help anything and a quick charge probably doesn't either. There's a big post about it on the zen kernel thread.
It's more of a Nexus thing. My N7 2013 does this all the time. Happened only a few months after release. Download an app called Battery Calibrator. Can't remember if I got it from here or from the PlayStore. It requires root access.
So.....are you on a custom rom or stock? If custom rom there's your problem right there, check for an update. If on stock also make sure your on the latest build. If all else fails do a factory reset. If problems persists just put in a warranty claim with Motorola.

Question Accubattery showing Battery health at 47% for a new phone (1 month old)

I purchased this about a month ago. I have been reading a lot of posts out here about people having fairly low battery life. So I had installed Accubattery to see if the discharge is abnormal. I checked today and it seems like Accubattery is claiming that my battery is only at 50~% health. Now I am unsure that if this is because it is a genuine fault or because this phone is supposed to have 2 2500mAh batteries and Accubattery is detecting only one of them. Any idea about this?

I've had my 11T Pro for roughly two weeks and I have the same issue.
It doesn't read charging speed correctly which confuses it's health calculations.

Those SOT numbers seem erratic. Some reasonable, others look impossible.
When you're using the browser not watching vids the usage should low.
As the previous poster mentioned it may just not have good sensing for battery usage.
Accubattery is only as good as the data it's getting. Even then it can screw up. I don't understand what's going on there.
Rather strange. I don't have that phone so I don't know what it's nominal run time should be. If it's running cool and you can get 8-10 hours SOT you're probably in the ball park.

Hmmm, okay. I'll continue observing my phone's behaviour then. I do get over 8-10 hours SOT on medium usage. Additionally, I read from other threads that the 120W charger isn't charging the phone fully and it makes sense to charge with a lower power charger. So I will try that as well. Will keep this thread updated if I see any improvements.
Accubattery doesn't work well with dual battery setup, that's why it's showing Battery health at 47%.
Set design capacity to 2500.
11T PRO has 2x 2500mah battery for ultra fast charging. Set the design capacity to 2500 and you will be fine.

This presents a potential problem in the future as one battery can degrade and fail independently of the other. You really need to be able to monitoring both.
If the manufacturer designed it properly each battery should have its own power controller in a perfect world. Not sure if this is so on any of the dual battery phones...

Question Why my battery life is so low?

I got this phone after seeing tons of reviews that Samsung S23 has amazing battery life
But i am ending up charging my phone twice a day because of very less battery life.
I am not a power user, mostly using phone for browsing and texting.
Yet the SOT is still so less?
I am using light mode in battery settings - Adaptive refresh rate - mostly wifi- Dual Sim 5G
25W official Samsung charger.

From your picture you can't see that the battery has been charged for the last 19 hours.
So where are those twice daily charges?
You are using two sims, if the signal is not great or will drain battery.
First of all, turning 5G for dual sims drains the battery so fast and secondly, I can see very well from the image you posted that you haven't charged your phone for 19 hours and some and that's great battery life to me. Also, if you happen to be using your screen at 2k or so, you better lower it at 720p or at least 1080p cause remember that galaxy S23 is only 3900 mAh and that's not a very big battery capacity like its bigger brother the S23 Ultra which is 5000 mAh and can pretty well handle intensive work! Hope my answer helped you.

For those who are saying i didn't charge it from 19 hours, please note that standby time was long because i charged it at 12am last night and then binge watched Netflix on TV, slept late and then woke up late too.
So mostly it was standby.
If i am using it regularly, then the SOT is very less.
Please see the SOT in the screenshot.

neither twitter nor instagram... and facebook is the most offending application of the battery in the android world, i agree with you
removed due to lack of accurate and or useful infromation
You have two sim cards active, three and a half hour of screen on time, and 19 hours of screen off time. I think it is great.
Peogle that shows a great screen on time, they do not stop using it. No screen off time.
