Dead battery!!! - Redmi Note 8 Guides, News, & Discussion

Hey, got a weird issue with my device.
Just 4 years old piece and already this has a dead battery!!! Cannot use it anymore basically... drains overnight on airplane mode from 75-80% to 0 in 7 hours!!! Last night I left it fully charged and shut down just to not starting anymore this morning because there is no power left, battery is EMPTY!!! Just barely started to charge!!! Something is wrong with this phone, really wrong!!!
I tried custom roms but the phone has the same behavior... so I came back to MIUI 12.5 just to be in the same position and to have the same conclusion: I HAVE A DEAD BATTERY!!!
I went back to my old Redmi Note 5 Pro with a custom rom... just like knew. How is this even possible??? An older device, with same amount of use have a better battery life than a newer device??? Different battery manufacturer, some production flaw in the battery production? Either way, conclusion is clear: NEW BATTERY... so, so disappointed by this situation...

Batteries get old and die , you have to change it , or maybe there is a short circuit on the motherboard , best option is to take it to a repair shop

I know.
But I found out that in fact my phone is only 2 years and 3 months old??? So, is this battery old enough to die? I guess there is something else here.
In the meantime, I already change the battery, sadly not with an original one... and so far so good, but only a few days passed. This battery however is acting strange! Does not charge more than 86%. Aida64 reports battery full at this precent... but I guess time will tell if I made a bad/ good choice.

encounter the same problem after 4 years of using redmi note 8 battery drains so fast unlike before and changing the battery to a new one it either does not fully charges it to 100 percent and it shutdown when my battery percent is around 20 or so percent but when I try to connect a charge and remove it, it will open up to that 20% or so percentage and continue to be used, I'm guessing the it need a battery calibration but I know really know what to follow on the internet.

Tilt Battery Drain During Phone Calls

OK, I know battery life is always an issue with PDA phones. I'm never far from a charger. I'm fine as long as I'm just checking e-mail (4 accounts, once an hour) and a little light web surfing with Opera Mini.
The problem arises when I use my phone as...well...a phone.
My Tilt loses battery power at an alarming rate when I'm talking on the phone. A 20 minute conversation will easily cost me 40% of my battery.
I'm usually in a non-3G area, so I'm on Edge. I normally have a good, strong 4-bar signal. Even when I'm in a 3G area, I use a different comm manager to turn off 3G to conserve power. I use KaiserTweak and select all the "Advised" settings in the power-related sections.
I've tried several different radios, but haven't noticed an improvement.
Does anyone have any ideas or recommendations on improving the efficiency of my Tilt in phone mode?
I have the same problem.
I have 3 batteries. 2 Samsungs and 1 Dynapak. Each battery lasts about 3 hours in standby. The phone is always warm as well. I have a utility that shows the phone is running around 380mAh current. That's seems pretty high.
I think theres something seriously wrong with certain batches of these phones.
these phones r seriously poor for battery life.. i love the htc but they slowly being overttaken by other phones.. shame!
maybe depends on the battery and ROM/radio because my Kaiser lasts 1 gay of VERY heavy usage+calling, and in stand by can lasts 6 days at least.

Really??
So, what battery are you using? Which ROM? Which radio?

mine too or maybe more. Normally I charge every 2 days.
Seriously though, hasn't this topic been beat to death with a stylus?
Ask youself this, how is your battery and what all is running on the phone?
If the battery is a year old then just accept that it's shelf life is over with. If your phone is always warm that would general mean that one of the radios is running, Wifi , data, gps? If any of those are running all of the time or when you are not using it, then your draining the battery.
I have a friend that beat himself up trying to figure out why his battery would drain so fast, he reflashed the phone 3 times a day etc etc etc. He just could not accept that it was a crappy battery. I got another (used battery) and it worked fine.

Me too used to get about 2 days with a 2700 that is being registered correctly, i now tell everyone to not phone me "well they don't listen just like no one does" so i block all incoming calls with MagiCall, to what point do i have a phone now? To flash & twaek and text
"Am kinda joking but my stylus is now half the size due to this topic"
Buy a new battery.
I don't dig long phone calls unless there is something going on. Too many people just want to hang out on the phone and say nothing.

"The loss of battery was due to phonecall and radio i'm not moaning either i expect the battery life to not be perfect on any WM phone"
Well yeah radio version help too.

This isn't my first foray into these HTC devices. I've been using them for nearly 2 years now, and I know the battery life on these devices isn't what it is on something like my old RAZR. I'm just fine with that; since the Tilt does so much more, I don't expect the charge to last a week like my RAZR did. But this drain while using the phone is driving me nuts.
FYI, I know to keep WiFi and GPS off, and to use KaiserTweak to shut down data connections when they're not being used. If I don't use the phone or surf, the battery will easily last me 2 days, and that's with checking 4 e-mail accounts every hour, and with SBSH PocketWeather getting updates every 2 hours. But talk on the phone, and it's a different story. I talked to my wife for about 30 minutes last night and went from 80% to 20% battery level.
The battery is only about 7-8 months old. Still, I ordered a new 1600ma battery last week, and it should be here in a day or two. I'm hoping that solves the problem.
It's possible that the battery you have now is under warranty. (if you bought the phone new)
good luck.

Unfortunately, it was a refurb, and the warranty expired a long time ago. The new battery wasn't exactly a budget killer.
Well my battery seems to be working now.
Phone is no longer hot all the time, and my utility says I'm using between 1 and 64 mA. That's much better than the 350+ mA it was sucking before.
I didn't do a damn thing different either. Didn't change any settings for the radios, didn't reflash, etc..
Some people think that the GPS get's stuck in the "on" position and there's no way to turn it off, short of opening and closing GPS Aware programs repeatedly until your current usage drops in the sub 100 mA range.
Always discharge your battery fully as possible at least 1 a week to ensure your battery last longer, lots of charges above the threshold will diminish your batteries life and capacity. The Kaiser is a powerful device and it is obvious to anyone that this requires power to run it, so the battery wont last for days. :-(

HUH???????
These are Lithium batteries, we aren't in the 90's anymore buddy.. My phone lasts for at least 2 days and sometimes 3 (the phone is over a year old too)..
Welcome to the year 2009
"1. Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half.
Problem is battery memory doesn’t apply to Lithium batteries, this advice was meant for Nickel based batteries. Fully discharging your Lithium battery frequently can actually be quite harmful to your battery’s health, possibly rendering it completely unusable if energy levels go too low.
The good news is today’s lithium batteries have a safety circuit in place to insure the battery doesn’t reach the point of no return. The safety circuit isn’t fool proof of course, if you leave your battery completely drained for a few days, even the circuit’s protective measures won’t save it.
"
INFACT it's recommended to leave a little bit of a charge before charging or storing.

Be that as it may, when you get a new battery you still have to use it for a few weeks before the phone reports battery levels accurately. The phone may still shut down when WM thinks it's almost empty, regardless if it's actually empty or not. Just try it, battery life improves over the first few weeks of usage, and your battery level readings will get more stable (instead of dropping to 50% in 10 minutes and then proceeding to stay there for 6 hours).
BTW my kaiser lasts about 3 days as well, with fairly heavy usage.
No fair, I want a bazillion stars next to my name too.
I Think this guy has had the phone and battery for a little while, so the few weeks thing might not be an option. (well at least the battery he was posting about)

As refered to your reply, i didnt mean discharge fully completely i meant the cut off point would stop you anyhow, i meant to bring it to about 10%, i found that using the battery until it reaches 10-12% far by decreases battery drain when it is fully charged again, this is only 1 in a while though not frequently. I understand lithuim-ion doesnt have a memory effect problem, but there is such thing as variable current influencing different cells which can either benefit or make it worst, there is a lot of debate as to whether this improves it or not.
Great tip, keep it cool and away from your pocket pants because heat kills it.
Dude thats no fun to keep it out of your pocket,

[Q] Battery dead after a year of usage

I've had my SGS Plus for a bit over a year now and the battery died few weeks ago.
It started with reboots, mainly with high battery drain use like browsing and gaming. When it tried to reboot, came a pop-up telling that I should connect my phone to a charger even tho I had plenty of juice left, and then it shut down the phone because the battery level was too low. When it finally booted after 3-5 reboots caused by low battery, battery level was ~5-8%, and it started to charge itself slowly, so that it would almost reach the level It had before the reboot in a few hours.
The battery lasted +2 days on average with my use, so it definitely has not been charged too many times (150-200 charge cycles). Samsung gives a six month warranty for the battery, so no help from there. The battery itself had swollen ~1-2 mm, that how I got a clue where to look for the fault.
Do you consider this normal? How long has your battery been serving you?
The battery of my i9000 still works after 2 years. Batterys are quite unpredictable so IMo it's not something you could blame on Samsung unless everybody would have this problem. In other words yes I think it's normal, but you are unlucky.
It isn't a big problem either since you can buy a replacement for just a few dollars if you don't care it's not official. The i9001 battery has more capacity though so they are either expensive or hard to find.

New Battery - What procedures to be done?

Hey guys! So I am having now turning 3 years old Xiaomi Mi3. It is still working pretty good with all these roms we've got credit to the great developers we have at XDA. The only problem I'm having is with the battery life. Previously it would last whole day. Now I'm charging it thrice daily.
So I ordered a new battery and replaced it.
The problem is at around 20 % of the battery, the phone died suddenly and when I put it in charging it flashed the notification light as if the battery is completely drained. Mind it that after replacement, I straight away charged the battery to 100% and then calibrated using battery calibration app by Nema.
After the phone died, I put it in offline charging and didn't reboot the phone until it was totally charged and then rebooted. It is now working fine!
The battery is holding better than what I was having but still, it goes down easily.
I am a heavy user! Lots of browsing, ebooks, emails, whatsapp, camera, etc.
Is anything else needed to be done.?
I am currently on second battery cycle of the new battery. Right now I got 2 hours 10 min SOT and 45% still left.
I am pretty sure, even this is not going to last the whole day as it used to do once back when the phone was new!
BTW am on NOS and it is pretty stable and generally always on 3g.
Please advise!
If you got the battery from official service center only then expect it to work as it used to do when the phone was new. Batteries from eBay, amazon and other websites won't give backup as the original one does because they aren't original ones, typically such batteries have 60% backup when compared to original one.

The thing is that the service center guy tells me that they have stopped importing parts of Xiaomi Mi3. I tried it in another center, they told me that it will cost 1500Rs for the battery and 600Rs for installation and service charges.
So I got it from ebay at 300Rs and replaced myself.
Probably you are right and this won't be giving any improvement to me! I just gave it a try so that I can wait for a month or so for newer phone launches. But I guess I have to rely more on charger than on battery
got a new battery for 300₹ from ebay..replaced it myself..3 yrs is more than enough from a single battery..battery backup ki great..m getting around 4.5-5hrs of SOT..probably which i was getting when i bought this phone..currently on DU. i am on wifi almost all the time.

Can you post a link?Does the device shut off at 20% battery?
Also can you check the battery temperature while charging?The one I bought from ebay never goes above 25.

Question Brand New 10 pro, defective battery?

So I just got a new 10 pro from OnePlus a few days ago. Idk if If the battery is suppose to be this bad or if it's my unit itself. I know battery apps aren't usually super accurate but AccuBattery reports the battery design capacity as 4040ma. It's suppose to be a 5000 ma battery right? I have it set up as half brightness, only cell data active, no wifi, no bt, no NFC, no location, nothing else is on. I hardly use it, literally, maybe read reddit for a little on my lunch breaks. After a 8hr shif it's down to 20% with less than an hour of screen on time, about 45 mins id say. Is this phone this bad with battery? Is it from sitting in storage at OnePlus?, or should I return this?
Just doesn't seem right to me. I had a brand new 7 pro since launch day and that lasted most of the day with location, bt, high brightness playing Pokemon go and had a degraded battery with only 3450ma out of 4000ma left...
Sounds very defective, id return it or claim warranty or something
Lol, AccuBattery probably didn't detect the capacity right. Adjust it manually, give it a few charges (up to 80% for the best results) and then you'll have an ESTIMATE battery health. As for the drain, you may have something running in the background. I'd check that with root and something like FKM to see which process could be responsible.
Thanks to both responses.
I adjusted the design capacity to 5k. Right now it says estimated capacity 2475ma, which with the way it doesn't last even an 8hr shift with almost no use seems right on the dot...
Il try the charging thing and see what the estimate is. But after a week I figured even with the design capacity being wrong that it would estimate it way higher. I know AccuBattery isn't the best way to measure things. Il give it a few days. I still have til next Saturday to return it.
I had a bad habit of charging my 7pro literally every time it dropped below 40% when I was at work every day, so that's probably why that battery degraded so much, and id plug it in when I was driving too. Trying not to ruin this one like that. But it's looking like a return is in order cause with a 1000ma bigger batter than my 7pro, it should last at least what that one did, only you would think being brand new, alot longer...
I'm stupid.. I think I forgot to check the setting for dual cell battery in settings. Now it says 4951/5000. That seems more like it. And weirdly enough it has lasted a lot longer today than yesterday. I restarted a few times this morning. I think you were right about a process draining an absurd amount of battery the last week I've been using it.
Hopefully this will resolve itself before my return period is up, cause other than battery life this phone is pretty awesome so far. It's sad to see not much development on here for it yet. I'm use to seeing so many roms and stuff coming from the 7 pro.

Rapid change in battery life

Hello, I've had my p30 pro for almost 4 years and the battery life has obviously degraded over time, but as of 3 days ago it only lasts about 4 to 5 hours. Nothing has changed on my phone, and it easily lasted a full day before this.
I'm going to get a new battery out in as I think that's probably the issue, but thought I'd post here to see if it could be something else as it happened all of a sudden which I find odd.
Thanks
Phone battery doesn't last longer. It will degraded as it gets older. Change the battery it might be good to go.
Ya 98% sure that's it, I'm going to bring it in tomorrow for a new battery, just weird that it went form lasting around 12 hours to pretty much 4 overnight. I've never had a battery degrade so rapidly before. Would just suck to spend $100 that could go towards a new phone on a battery if that's not it.

Maybe try to do hard reset, and try using it for time being. If the issue still persist, changing the battery it's the only option
That's actually a great idea, didn't even think about that.
Thanks for the help.
