Xiaomi battery issue

[The_Ogre]

I bought two Redmi Note 5's last year - one for myself and one for the wife.

My wife spends around 3 to 4 hours per day on hers as part of her business. Me, on the other hand, hardly ever makes or fields calls because I hate talking on the phone.

I've always though of myself as someone who takes very good care of my battery. The moment I get to the office, I plug my phone into my PC, my phone almost never reaches 50% battery power remaining. Until the last week or so when I was away from home and nowhere near a charger.

Here's the kicker, as soon as my phone hits around 20% battery life, it shuts off, while she can happily still use her phone at 2%. Further to that, she regularly finds herself with the phone dying one her because she literally finished the battery.

I'm just wondering how such a discrepancy is possible since I've ordered both phones at the same time from GearBest, so there's a 99% chance that it's from the same batch.

The point I'm trying to make is that it seems the OCD related to always keeping your phone charged seems to be false, or am I missing something?

so battery memory is not meant to be a thing on modern batteries, but what you describe seems like yours is doing just that. but there are many more factors, for example you could have over charged your battery if the protection failed, yours could be a manufacturing defect etc. my bet is your battery is probably a bit swollen and would spin on a spin test

Valid point, I think modern batteries are not what it used to be. Either that or the software is reporting an incorrect reading.

Actually, let me compare software versions. Will post in a few.

I think you may have messed up with the charge-recharge cycles.

The whole OCD thing about battery charging led me to one conclusion: the stress of trying to maintain these "optimal charging methods" will kill you before you see the benefits.

I always charge my phone overnight even though I comfortably get 2 days battery life. Living in the country and having livestock and forest fires, means that, in emergency, I have a full battery if I'm called out at night. I don't believe that this negatively affects the battery.

I would say that it is just the individual battery that is at fault. Lithium batteries are great until they go wrong. One of the reasons for the stringent air cargo regulations regarding lithium batteries.

I would just say that that particular battery is faulty.

Xiaomi Mi Max 3 coming on 1 year old. Normally charge when battery hits 50-40%. Can still get over 2 days of heavy use out of the phone.
OP: I think you have a faulty battery not induced by your charge routine.

Ag, it is just moeg . Electronics are unpredictable. Get a new battery. Don't bother with the whole battery memory thing and process to get it working again. Also don't bother with the whole maintenance thing. Just use the phone as what is the most comfortable and get a new battery when the time comes.

Maybe try a few charge - discharge cycles: charge to 100%, then play a video till it switches off. Rinse and repeat 2 or 3 time.

This may condition the battery, if there is not yet permanent battery damage.

My opinion. Not worth it. Battery is done. Just get new one and no more headaches.

I was about to say while battery memory is no longer a thing software memory can be.

Maybe a good old full discharge a recharge would calibrate it better.

Also being away from home could also just mean your died earlier in due to uncommon bad signal.

Do the same with all my phones. I just charge mine overnight. Using a Redmi Note 3 and the battery is still amazing.

Just throw out the Chinese junk and get an iPhone

Maybe it has to do with you using your pC to charge the phone.
May the amperage is too low?

iPhones are Chinese, and their batteries are notoriously kak also

'I've always though of myself as someone who takes very good care of my battery. The moment I get to the office, I plug my phone into my PC'

That was your mistake right there
Never do that.
Charge it with a proper phone charger designed to charge a phone battery
Battery is shot.

Hmm interesting, I've always thought it best to let the phone run down completely and then charge it FULLY. So far has served me well, although with the skedonk I have now I charge whenever which was also fine for a while but now definitely needs a new battery as its capacity sucks and its a tad swollen as well.

That's the worst thing to do with a Li-on battery.
Never let it run completely dead

100%

However with the way people have become so attached to the things it's impossible for them to wait that long.
I always advise people as a rule of thumb to charge only when it's between 30 - 40% battery life and always disconnect once 100% is reached

By completely dead I mean the % on the phone which just means the voltage has reached the minimum of the tolerance, 3.2v or something I think. Its not actually completely dead.

Charging a 'tad swollen' battery is also a very bad idea

I leave it on 100% a lot, obviously whilst I'm having a kiep it'll be sitting at 100%.

Something odd that happens on this phone if I rape the power by downloading on the PC through the hotspot it'll run itself dead whilst on charge and showing 100% ie its using more power than the battery and the charger can provide at any one time and then slowly depletes but the number showing never changes.
