Xiaomi Redmi Note 7 Pro Battery replacement - Xiaomi Redmi Note 7 Pro Questions & Answers

Yesterday, my phone stopped working. It was stuck in a bootloop. The device turns on for a while when the charger is connected and soon switches off. I took the device to the nearest service center where they confirmed that the battery is dead. However, the worst part is that the battery is no longer available at the service center. They say that the spare parts won't be available since the product has reached the end of its life. Is there any way to purchase a genuine battery? What are the risks associated with using a third-party battery?

Not sure where are you? I'm in China and I found the battery can be bought from Taobao. I have changed the battery for my cell phone for many times and I didn't find any difference for the battery from other brand.

Battery Charging Issue

I know there is a bug in which after an overnight charge, the unit is unresponsive unitl you soft reset it. I've read the thread. My TP exhibits this problem as well. However, mine seems to have an additional problem not mentioned in that thread. After charging overnight, my TP IS NOT CHARGED! After an overnight charge, the battery is nearly dead and a soft reset does not fix that. It has happened several times now. After plugging it into the charger before bed, I confirm that the charge light is on and that it shows charging on the status screen, however, THE BATTERY IS NOT CHARGING. Has anyone else experienced this quirk? It doesn't always do this, however, so I'm very confused about what is happening.
Dumb question - but are you using the factory charger? I had a problem when I purchased my Touch Pro in the fact that I used another charger which also was USB for another phone, but for some reason had that problem. Using the charger supplied with the phone fixed it.

Yup. Factory charger and cable. Not a dumb question, BTW. That could have very well been the problem although any USB charger should work.
What about if you turn the phone off and charge?
On a related issue, I used TomTom the other day for a 1 hour trip with the phone on a USB lighter socket charger. Started with 48% full battery, when I finished the battery was down to 30%!!! Basically the phone uses more power than the USB can provide when the screen+GPS is on!! I also find plugging the phone into the charger with the screen on & WiFi on will mean the phone charges at a speed of 1% every 8 minutes - taking all day to charge from empty!
To ease the problems I purchased a separate phone+battery cradle off eBay and a spare battery. I swap to the charged battery every morning and put the other one in to charge. The used battery is usually at 25% after a good days use. Before I did this and charged using the USB plug I used to get 6 hours use before needing to re-charge.
Disconnect the cable from the factory charger and plug in in your PC, see if it charges there. If it does, then you can return your charger, if it doesn't then i'd return my TP.
I have had the Touch Pro for eleven days(got in October 31,2008) and I have issues with the phone. First, I love this phone, however, the battery will not hold a charge. I started with a fully charged battery, used sprint navigation to direct me on a 2 hour trip. My phone was dead by the time I got to my destination. The phone was extremely hot, I mean extremely hot during the entire trip. The next day I took the phone into the sprint store and they switched the battery and told me that the phone check out okay. for the next several days, i used the phone sparingly to see if the battery was okay. I made about 7 calls and 12 text messages, my battery was down 3 bars after being fully charged. I tried the navigation within the city limits and the phone again stared to get hot. My sprint picturemail would not work, it takes hours to send a picturemail. I call customer care and talked with technical support, who did not have a clue about the phone, they had me on hold, researchec, told me to do a few things and then had me to perform a hard reset. The picturemail worked for a few messages and then it started to take hours to send a picturemail. i then went into a sprint store for ready now service to see if there was something I was doing that was causing the battery loss, etc. The CSR in the store did not have a clue about the phone. He went through the computer told me a few things to do and that was it. My battery continued to perform poorly, so I again called customer care and was told afte a serious of conversations and procedures that i need to have the phone replace and that my phone could be defective. They told me to go in to a store and have them make the switch. Well, there are no phones in any of the stores in my area. I call customer care again and asked them to look at the notes on my account and send me a replacement phone, because there are none available in the stores. That was a horror story and i currently have an expensive phone that i have to keep on the charger. i actually purchased a universal charger from sprint that can be used in your car and/or in a wall socket to make certain I don't lose my charge. I think the phone is over priced for how it is operating for me. Sprint should provide an additional battery for the touch pro like they do for the Instinct. The should also include the universal charger in the box. The phone cost to much to not operate better. The sprint picture mail sucks, The sprint TV sucks, but the phone is really nice, if sprint can correct the issues mentioned.
I don't charge it at night cuz i don't like to "overcharge", so i usually charge it when i get home b4 I sleep. I have been considering getting an additional battery with a dedicated battery charger from HTC though. ever gave that a thought?
I seem to be having this same issue with my Fuze that I just got yesterday. After a full night on charger it's at 82%. I'm going to try it over usb on pc to see if it gets any higher otherwise I'll be taking it back to the store today.
The HTC touch pro (with factory ROM) is protected from overloading. Which means that overnight it will load for about 3 hours from an empty battery and then it is full (white light will go from sliding to full circle). After that the charging stops. Which means that if you sleep for 8 hours, the remaining 5 hours your phone will be using the battery.
Now the question remains, what is drianing your battery in 5 hours? The initial suspects are GPS (any GPS software should be cleared from memory, press the most right corner icon to see what's running), the wifi or the HSPA / 3G connection. Use comm manager to put those off.
Of course, the second option is that the charging is not happening because of a defect, in that case return it to the shop.
Pretty sure this is a common problem, I don't think returning the phone will solve a thing.
My phone does the same. Though if you charge it with the phone turned off, it charges fine. I purchased a separate charger and spare battery and just swap them over when I need to (1.5 days with moderate usage).
Pretty sure this is all down to the phone using more power than it should be, hopefully future rom updates will fix this. Even when using Tomtom in the car with the phone charging on a USB cigarette charge cable can't charge it - it actually has less charge at the end of a long journey.
Oh and I can also mention that I have the original HTC battery and two spare batteries (which look like copies with, the HTC sticker is there but not quite the same). The spare batteries act just the same as the original HTC battery.

HTC s640 Battery Issues?

Hi Folks,
My s640 seems to have developed an issue with the battery. It will get to about 50% and stay there for most of the day then suddenly I get the low and critical warnings, then off. The warnings then off sequence happens within about 10 seconds of getting the first warning. On one occasion I got the low and critical warnings, but then the phone reported 268% battery remaining.
Is/has anyone else experienced this issue or anything similar? I'm wondering if it is the phone or the battery.
Thanks.
I am having the same trouble.
I'll fully Charge my battery and then disconnect it and us it for about 10 minutes and suddenly it will drop my call, turn off my bluetooth and disable the radio (network), and if I don't plug it in, within 30 seconds it shuts off. If I remove the battery, hold the power button for 5 seconds and the put the battery back in and turn it on then I have my battery shows 90+% free.
I'm not sure if it's the battery or the phone.
have you tried running the battery till it won't turn on the phone. Then charging it up again?
maybe a hard reset may help?

Yes I too am having this issue since rom upgrade so is a friend, he just purchased new battery from Telus but they shipped wrong one. Will update if new battery resolves his issues. I went throught three phones with brand new battery they all did same thing Battery is not HTC 20 dolllar aftermarket one (just before warranty expired). Have gotten 400 credit for new phone but nothing like this one out there except Touch Pro Diamond and I hear even with new battery that phone battery life is too short to last through day. Get feeling Telus broke something in software with Rom update used to be when phone battery was expiring a red light would blink (opposite of blue tooth light) now it is only notifications from WM that phone battery is critically low and shuts of radio etc. yet you plug phone in and it's charged 10 minutes later makes no sense. Rechargable batteries voltage change with charge the interesting thing when I pull my battery the voltage is the same charged or just after error messages (I have a very expensive True RMS Voltmeter from work that has been calibrated in last year) but without load this isn't an accurate test. Does make me think something is not right and beleive it software related for more see my post in Howrds Forums under phone model.
I am having the same issue after the ROM update, not sure if it's the cause. Already replaced a battery on warranty for not holding charge. But now I have had the phone over a year so telus wants me to buy a battery for $80. I know based on this information i'll be wasting my money.
i want stuff to work for more than a year what the hell is money good for?
any fixes or updates wether the new battery helped??
I replaced the battery on my phone and these odd issue I was having are gone guess we have to face the fact that you need to purchase a replacement once a year hopefully it will last a year my problems start just short of a year.
I just got my new battery from here http://www.longlast-battery.com/productCart/pc/viewPrd.asp?idcategory=0&idproduct=17483
I will post after I get it full charged and try it for a day or two
where did you get yours from?
well the battery didn't even last an hour on the way to work.
#1 it was similar but 2-3mm shorter than the OEM and barely touched the contacts on the phone.
#2 charged overnight ok and said 100% charged then withing 20min it said low battery then died shortly after
#3 would not charge a second time (on 2 of my wall chargers, two usb and 1 car charger) Just the red light would light up. Tried jiggling the battery but nothing not even a flashing red light.
so much for a battery bought from the US. Waiting for RMA

I purchased a battery from E-bay and it would not charge at all. Existing charge in battery was enough for me to know that my issues were battery related after all as phone lasted for quite awhile. Tried charging ebay battery for close to 12 hours no go, so returned it for full refund. Called Telus because my calls in were while I was under warranty still but it had since expired they credited my account for the price of battery over a couple of years (1.5 batteries really) to make up for battery not lasting more than a year...hope that makes sense. Doubt I will buy another HTC with todays battery technology there is no reason one of these batties can't last 2-3 years if taken care of. Just a money grab telus/htc on their part in my opinion.
Gave the battery I got from longlast-battery another try.
the battery is CS-DS640SL 1250mAh 3.7V
I got it to charge by turning off the phone and plugging it into a usb port on my PC. Took about 6 hours to charge to 100%.
Won't charge when phone is on which is weird. Even at 90+% charge.
Lasted a full day without charging. That's a good thing I guess. Even when I restarted, it didn't lose the typical 10% drop in charge the other battery does.
I'm going to discharge it and charge it three times to see if it starts working properly and letting me charge it normally. Was a tip someone gave me. Won't hurt anything, and if it doesn't work I can still send it back.
Curious what you guys think. do you think it's a bad battery and I should just get an exchange, or I should just get my money back, and shell out the $100+ for a Telus battery?
Well the longlast battery test failed badly. Lasted about half a day with minimum calls and data use. No wifi no bluetooth. After it died I took it out and let it sit for a bit as the battery was fairly warm. After I put it back in, it said I had about %40 left. Very odd. And it lasted for another two hours before dying.
Now it's back at the won't charge stage. So I finally got an RMA number, so this one is going back.
Hitting Telus on the way home to pony up for a new battery. Getting the extended one as it's only $20 more. Hopefully this one will last more than a year - then I can get another phone (got to love 3yr retention contracts that end early )
I've created a Facebook group to act as a petition for everyone with the notorious battery life problem.
Join the group here, it's open to everyone:
http://www.facebook.com/group.php?gid=100925126406
Share your experiences dealing with Telus positive or negative ones.. or tell us if you've been able to fix the problem by hacking the device. Anything at all that will help the people still stuck with this phone.
I have done some efforts regarding battery capacity measurement Just lookup this thread: http://forum.xda-developers.com/showthread.php?p=5558383#post5558383

[Q] Sudden Unexplained Increase in Battery Drain

Stock 2.3.6 with no changes to or updates in settings or installed software and I have been taking pretty good care of the battery in a 5 ½ month old Atrix 2 directly from Motorola and not previously used.
Several days ago battery drain when in standby when from approximately 0.5% per hour to 2.5 to 3% per hour. I did the following, although not necessarily in the order listed:
Bench tested battery at a battery shop – no problem found.
Verified settings and software. Cannot find anything that appears to be draining power, initiating communications, etc.
Pulled battery.
Hard data reset and tested drain rate with no additional software and had same problem as when normal software was installed.
Several deep cycles from 3% or less to full charge. In all cases mV appear in normal range of about 3542 mV at 3% to 4347 mV at 100%, again per Circle Battery Widget.
Broke down and called Motorola and although they tried to be more helpful than normal, the only suggestion that they could offer was to try another battery, which I do not currently possess and AT&T would not allow a short term lending even had they had one available.
99% of all charging is via stock wall charger, spot use of car adapter with appropriate specs when using GPS.
Typically recharge starting in range of 5-15% and charge to 100% as indicated by Circle Battery Widget.
Battery usage in standby shows about an even split between Cell Standby, Phone Idle and Bluetooth each about 32% of usage when in standby. Have always left Bluetooth on 24/7 except when charging and battery drain was only about 0.5% per hour. I even tested for several hours with bluetooth off and this did not affect the rapid drain.
Contacts are clean.
I even use Motorola USB cables both from my PC for data transfer and also with the wall charger.
No exposure to excessive heat/cold.
If anyone has any thoughts, I would greatly appreciate any help. Otherwise my next steps are to call Motorola back Sunday morning (U.S. time zones) and probably order an OEM battery from a reputable source allowing for U.S. holiday on Monday. Unsure how Motorola will treat this as warranty since 1) this phone is a replacement for Atrix 4G problems whose warranty would be expired, and, 2) batteries have weak warranty coverage anyway since so much of that is beyond their control.
Thanks
Same here recently.
My battery life has gotten a lot shorter (and cell reception worse). Most of my 'battery usage' is coming from cell stand-by.
Overcharged Battery
How long are you leaving the A2 on the charger? MTL you may have "overcharged" the battery, overloading the memory in the battery itself, therefore resulting in less usage time from a "fully charged" battery.
Typically, as a sales rep, I recommend my customers only charge their phone for the full 4-8 hours, when it is the FIRST time they charge their phone. typically after that, it takes only 2-2.5 hours to provide the phone with a full charge. Over charging will fry the memory and make the battery hold less charge and over a period of time eventually kill the battery, making you have to buy a new one.
P.S. If I am completely off base please let me know. Yes I am noob, but this info was actually part of my training courses so I'd love to tell them they're wrong. Hope I was helpful.

The phone electronics will not actually allow overcharging. you will have problems if you do overcharge it but you can't do that while it is in the phone.

Thanks but in addition to any designed protection against overcharging I also pull the phone off the charger as soon as practicable after hitting 100% per Circle Battery with the exception being when using GPS which means that the phone will charge very slowly to 100% and remain connected to the charger until the next stop in my trip. The phone charges more slowly on the car adapter because the screen is constantly on along with running GPS and music software and streaming music via bluetooth.
I also try to make sure that I always disconnect the charger before starting or turning off the vehicle's engine. It may not be necessary anymore but that is an old habit.
Happening to me recently, before the battery lasted very long, but the past few days I arrive at night with 20% left. I tried doing a factory reset but it still the same. Also, the "cell standby" is the biggest consumer? I don't know what does that mean...

As far as I know 'cell standby' is basically your phone searching for a signal.
Remove any app that u suspect. If u have installed battery indicator pro, that's the culprit. Same happened to my phone when i had battery indicator pro. Install juice defender ultimate. Works a bit. Clear off d ram and reboot

For what little it may be worth replacing the battery showed the same problem and motorola now admits that this might be a motherboard issue and wants me to send the device to them for repair. They had their level 3 contract tech support review what I had done for troubleshooting and they agreed that the above steps plus replacing the battery had exhausted all possible options that can be taken outside a repair depot.
Those with similar problems may want to do the same and finally call motorola.

Wonderful, I am on my 3rd Atrix 2. Returned two previous because of the sd card reader/compatibility problems. The third one I received hasn't had the problem but now I can't go more than 8 hours without the battery going dead.
Cell standby is normally over 33% and Phone idle is normally at 30% or higher.
This happens whether I leave wifi on all day or turn it off.
Stock 2.3.6
I work from home and I have 5 bar signal strength from my house so there is no reason for my phone to constantly be searching for network signal.
Still happening to me. Today I was talking with an AT&T representative via online chat, and they only tell you to disable background data, and set it to super saver mode. They didn't want to listen that the phone before lasted until midnight with the battery still green and that now it goes red. The guy said that the phone is supposed to last 8.5 hours, since that is the talk time. I tried to explain that the talk time didn't work like that, but no good.
Finally, I went to an AT&T store and inquired about the issue. Since I'm within the 1 year warranty they are going to send me a new battery. If that doesn't fix the problem they said they would change my phone.

Google pixel 1 (5") depletes as it charges.

Basically my Google pixel has been having these issues since January/Feb
But the phone refused to fully charge it would stop at 98% and the battery wouldn't last long at all I used to get 4h screen on time and have like 20% left now I get 2h 22m with the replacement device that Google gave me.
I have had the device replaced four times, yes four. And I have tried to charge the device with no data on it and no email. So it would be a fair test.
With this, the fourth device, it charges, then reaches 100% then depletes while in the charger and not being used and so it has 97% after.
The device lasts no where near as long as it should and when I take it out of the charger in the morning it drops from 97% to 92% with 5 mins of use.
Google are now telling to replace it again. I am using the official charger.
Someone please advise me!
This is happening to my Pixel too. Also when battery has like 25% left, the phone suddenly power off, and it won't turn on until i charge it. When it boots, the battery indicator shows 1%. Truly weird. Idk if it's a software issue, a battery issue or wth is it. Hope somebody has a solution
Both of these sound like bad batteries.
@Zikohh, you're probably being given refurbished phones as replacements, and they don't have a new battery. I recommend you suggest them to pay for a battery replacement, rather than change the device again.

hopefully they will agree. Four replacements had the same behaviour. And yes they are all refurbs.

Two things try to update (may security update) and if not any better and you haven't already - try a factory reset my camera app caused similar stuff and a factory reset fixed it. But if you tried once don't bother just try updating it.

Oneplus 8 Battery Replacement Issue

Greetings! I went to repair service store and they replaced my OnePlus 8 Battery with a new one , two weeks ago. I have been using Accu Battery for checking battery health as i cannot use OnePlus Diagnosis app. It was showing me that the original battery had an 86% health after one year and half of using it and i decided it's time for a change.I am currently running Oxygen Os 12 C.26
After one day of using, i noticed that when the phone reaches 20% battery it's starting to get to 10% in a few seconds and then it switches off. After another day i noticed that when it reaches about 30% it's switches off. And then sometimes when i charge it to 100% it's discharging to 80-75% in a few seconds.
The staff from the repair service told me that the batteries are not original, they are just compatible, but they should usually work as intended. This is the 3rd battery that they replaced because the previous one that they replaced was only able to hold for 1 hour ( up to 20% charge).
They told me that they will get get an original battery from their supplier, and it will take two weeks to get it.
Can this be because the battery is not original ?
Or Can it be because of AccuBattery app that I'm using?
I could order an original battery from Ali Express , but i have already paid the service centre for it.
Let me know what you think
Thanks, Mike
