Battery Replacement

[Talha7866]

Hello there I think my battery has damaged it is showing unusual behaviour my phone switches off with 5-10% left I thought it might be a calibration issue but I've calibrated it many times the problem still persists also when I charge it in switched off condition the charging starts from 14% instead of 0. I've decided to replace my battery so I've a little query since Mi4i and Mi4c are identical can I use Mi4i's BM-33 battery instead of Mi4c's BM-35 ? Does anyone know please respond to my query.
Thanks in advance

No, they are not the same voltage. Get BM-35

I've inquired both have same voltage ? the only difference is the capacity mi4i's BM-33 has 30 mah more

Hi everyones
Think Mi4s battery should work in Mi4c ? I don't know about dimmension but the battery connector is still the same
Mi4s: BM-38
Mi4c: bM-35

Are u sure the connector is same? And how do you know?

 

[fmz90]

No i'm not sure but I saw the connector in "mi4s teardown" video and it look like the same

Yeah I've seen that too but mi4s is 1 millimeter wider than mi4c I don't think BM-38 will fit into Mi4c. Mi4i's BM-33 will surely fit but I don't know if they have same connector or not :/

I wouldn't replace my battery for such a behavior. Have you ever tried physically recalibrating the battery? Or did you use an app?
In case you didn't, let your phone almost run out of juice, then plug charger in and switch it off. Let it charge for 2-3 hours (depends on your charger Amperes) or something more, then turn phone on while still plugged in.

Yeah I've done it thanks for the help sir my phone is working fine now but it gets switched off when it becomes too hot at 9-10% its not a battery issue

I have the same problem, and purchase a new battery, and was worse.
tell me where to buy a genuine ORIGINAL

Actually I'm from India so I bought it from eBay India.
AliExpress might have original ones btw where did you buy ? Check AliExpress they'll​ definitely be having original ones

no, you can't buy original/genuine ones anywhere - the ones on aliexpress/ebay are better or worse replacements
I've bought one since I've got shutdowns at 25-30% , but the replacement is worse - after a month or two when I enjoyed the fact of having no random shutdowns, the capacity was dropping and I'm back to my original battery

try using slow charger (non-QC2.0) - after a couple of charges with 5V/1A sudden shutdown problems vanishes
