Battery Drain And Heating On 7.5.25 And 7.6.8 - Mi2s


Even good quality batteries at this point won't have the advertised mah because they have been manufactured 3-4 years ago.And batteries loose their capacity even if they are not being used, even if they are sealed on their package.
I've also avoided the "original" batteries for this reason, do you think the battery I bought is old?
 
orange is the original mi2 battery
Blue and white is the new purchase

Hi guys!
now i use both 2 batteryes per day; when I bought my Mi2 I also take a doky charge and now i use it to charg a battery while I use the other one.
Now I can survive.
I am waiting MiUi 9...

I have 5 batteries for my Mi2s, the three aftermarket and the two of them are the original and the big one blue with 3200mah. The three non-genuine are one nohon, one no-name, and one "genuine" orange. The orange is the worst. The Nohon one keeps 1600mah, and the other about 1500 mah.

If there is a small chance to find a good battery for this mobile, and you find it, please share your perfect catch... I am still waiting for the miracle.
 
I also have the 3200mah battery but i use a lot and now is dead.

I use the 2 batteries in the picture that I posted some time ago in this tread, both were manufactured in 2013 but I found some 2017 batteries on AliExpress
Unfortunately I think that a new battery can't make the miracle good luck.

dont know why, but im trying xiaomi.eu again and works fine (even with apks restored by titanium backup ) and 2 mods from ******* rom (cant use that because system free space isnt enought) and its goes really nice!

the fuking glitch while listening music still persist.....

Strange, I don't have this problem on stable...

My brother bought Mi6, in a month I will take his old Mi4 and my Mi2s will be free for testing.

Really? Have you tried it? How is the audio? Is it still Lollipop based?

Audio in last update is a bit lower, Hope It comes back Next Friday. Glitches still exist but much less than before. (Dolby atmos is always a good choice to improve audio quality)

Sadly yes, still 5.0.2...
 
Hi there! I have the same problems of battery drain on my mi2s with both developer and stable versions.
I bought a new genuine orange battery (production date 2016) this summer on AliExpress, but it drops from 30-40% to 0%. I tried to calibrate it without success:mad:, so I have put the old one again that is quite good yet. In addition, I bought also a charging port replacement, so I can try it about the fix mentioned above!!
Anyway my concerns now are the WiFi and network problems on both 8.2.1.0 and the 8.1.2.0 stable (I downgrade with the hope to fix them but still present). Mobile Network is really slow, while WiFi isn't stable at all because the connection is always present but frequently it doesn't exchange data, so I have to switch off and power on it again. Has someone these problems?
Grazie:)

I've never had this problem, but I read something similar on CM 12.1.1 @bugers's thread. I suggest you to make a clean install via MiFlash on fastboot mode.

Today I've installed new MiUi 7.9.21, Tomorrow live battery, stay tuned ;-)

When it comes to the audio glitches, can everybody please click “confirm bug“ in my bug report in the MIUI Forum. The more people confirm it, the higher the chance that the devs will fix it.

Here the report:

Thx for everybody who helps! :)

I'm still on last year's v8.1.2 because of that annoying issue.
