Battery problem - Redmi Note 2 Q&A, Help & Troubleshooting

Hello guys,
I have big problem with battery discharging.
My original battery got bloated and was lasting only 2 and a half hours of SOT, so i decided to change it with a new original one.
I changed it and even now, the new battery last even less, only 2 hours SOT (youtube).
I installed AccuBattery and tested the charge-discarge and life with it for a week and it sais that battery life is at 400 mah.
Is it possible for a new original battery?
Can something else be broken?
Please help me!

I found some baterys on ebay...... they looked kind of "strange" so I decided to keep searching.... nothing so far
Where
Where I can buy a battery for my Folio?
I found some batteries on ebay at http://www.ebay.com/itm/Genuine-Ori...8-battery-PA3836U-1BRS-PABAS238-/270859820087 . On contacting the seller he said that the batteries were original Toshiba manufactured (or made by their OEM for batteries), and thus had original Toshiba labeling. However, the battery was identical to the existing one, not a larger capacity battery. Any found larger capacity batteries?
Battery life fix from 2,5 hours to 5,5 hours!
I bought a used folio and in the original OS it had battery life of 2,5 hours after couple of complete charges. I then installed ICS CM9 and no change in battery life, the device shut itself off after 2,5 hrs.
Well after Googling I decided to try the battery stats reset in CWM. After 100% charge I did the battery stats reset in CWM and went to ICS to test the battery. After about 2,5 hours battery meter was showing 6%. 3hrs still 6%. 4hrs still 6%. 5hrs still 6%. Only after about 5,5hrs it dropped to 5% and about 15mins after that it was 1% and my device shut itself off. What an improvement! And I was using wlan and watching videos etc practically the whole time!
To fix the battery meter showing 6% for several hours I have used the device many times from 100% to lower than 6% and then charging the folio with power on. Now it shows 6% only for 45mins or so and I bet after couple more cycles it will be perfect! Then ill run it to 0% once more to be sure to make use of the whole battery.
So before you buy a new battery this is definately worth a try.
PS. You don't want to drain the battery to 0 % very often because this too will have a negative effect on battery life. Maybe once every 20 cycles is ok.
Wow, I'll try to reset it on CWM and see what happens. With a normal use is lasting about 3 hours before shutting down.
Do you have news for battery?
Thank you in advance.

Battery drain on stock marshmallow {non rooted}

Hello, i have some bad battery issues, my battery just disappears. According to 3C battery monitor the battery has capacity around 29~~ mAh. I have installed build 23.5.A.1.291. It wasn't so bad until i bought new smartwatch and i kept the bluetooth on during my time in school. I remember that i had even three days of battery on the KitKat 4.4.4, but now i have to charge every 10-12 hours. Also, i found someone who has same issue on Z3. Today i did factory res. and after using it had 97% i put it into sleep and didn't use it, after few hours it has around 85-83%.
It is soft charging function, it will charge your phone but not full capacity. This function will increase battery lifespan but reduce usage time
BTW, try charge your phone many times after installed new ROM, then it will stable
If not, maybe your battery has problem
I am thinking about changing the battery because AccuBattery has shown me that it has 2562 mAh, even if i heard that this app is not accurate. Also, i am thinking if its worth to pay 40 euro for battery change or buy a new phone like Xperia X or Google Pixel.

Battery Drain Issue

Hlw Guys, I am facing battery drain issue in my poco f1 for 4-5 days.....its draining like a hell. after full charged its draining 25% in just 30 mins of normal browsing.....its very bad... Yesterday night I full charged it go to bed.... after 6HR of not using phone its drained to 100 to 30%......Its really bad please if u have any solution then please tell me. And also explain me why its happening.... should I have to change my battery or something else can be done without doing this. ):
seems like you need to replace battery..
Check battery health in Accubattery. 15-20 sessions for a reliable estimate in case of partial charging sessions and less in case of near complete ones. If rooted the battery capacity can be checked from the built-in kernel profile.

Question Wonder issue

Hi guys , I have bought this phone for about a week, the problem is that when the battery percentage is 14 to 11, it drains within 30 seconds and then the consumption is normal, I sent it to the dealer for that. They installed the latest version of miui. This was useless and the problem is still there, does anyone have this problem? Or if there is a solution for it, I also did the calibration.
I dont really understand what you are saying, i usually charge my phone whenever it is at 20% or something but there have been instances where it dropped to 5% too but I never noticed it specifically from 14 to 11
I have been using it for about a year now, so far things are good at my end and in general i am satisfied with battery life and charging speeds.
If your phone charges up fast, and overall battery performance is good with 5-6 hours SOT until you reach 20% i think it's good
I have the exact same issue on my Poco X3 GT. When the battery reaches 14% it drops very fast to 11% and then everything goes normal again.
