[Resolved] Yu Yunicorn 5530 Battery no full charge - General Questions and Answers

I have been using YU Yunicorn for the past 1 year. It was great untill one day the battery % kept dropping instantly to 0. I had my phone flashed at the service center and it was normal again. But from the past 2 months the battery wouldn't charge after 88% , I had my phone flashed again the charging issue was solved but I noticed the battery % was dropping abruptly at certain percentages.
I think that it is a software related problem but I need someone to confirm it.
Thank you.

[Q] Battery problem

Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.

Battery issue ?

Hey everyone , recently when the batery reached 30 - 20 precents the phone shuts down .
meaning the battery just dropping to zero precent.
i dont certain if its a Rom issue it started hapening when i was on BrokenPOP and it also happening on Liberty sense .
what do u thinks guys ? need to replace the battery to a new one?
i think is a battery problem
I'm on Broken and had phone reaching 10 or 8% battery often. So I can't say it's a ROM fault especially as you have this on Liberty as well. Battery status got wiped after a full charge so it could be that you won't face this issue after several charging cycles

Waht's the age of your battery. Mine was 2 years old, and dropped to 0 from around 20 % in less than 2 minutes.
I changed the battery and it's behaving normally now. I'd say you should change yours, it can be found around 10 €.
well , U R right , my battery is 2 years and couple of months.. so replacing it is logical.
Also , Rapier Ur right too , after two full charging cycles the battery isnt dropping from 30-20 percents to zero it dropping normally now .. i'll see further behavior of the battery and decide to buy or not, thanks .

[Q]Battery dies at certain % even after calibrating battery!

Hello Folks,
I am facing a really hard issue on battery dying at certain % and showing "battery is too low,please charge for a while before you turn on" (written in english and chinese with a blue color screen), last time i was very worried when i faced the issue then i got its solution from googling and i came to know that it was battery calibration issue.. now again today suddenly while playing a game same issue occurred.. I had calibrated my battery a week ago by completely discharging and putting it on charge for 6 hours overnight without interruptions as i read in a guide. What must be wrong now? today it switched off on 16% before it was 19-20%.. Please help me and tell me a full proof guide to get my normal device functioning back..
ROM: CM 12.1 OS(stock and unrooted)
BOOTLOADER: Locked

Battery Problems - Visiual bug or Battery issue?

Dear Community,
since few days a problem with my Xiaomi Mi Mix 2s came out of nowhere. My phone charged very quickly but as soon I removed the charger, the battery drained extremely fast. I lost about 1% in 2 Mins. Then as i charged my phone it charged again super fast to 100%. When I restarted the phone after charging it came back with only 42% so I could charge the phone again. After installing an update the charging went slower so i thought maybe the problem was fixed. So i tried to restart after charging my phone again to 100% and it came back with 30%. But now it is already 4 hours at exactly 30% without loosing any "%". Do you guys think my battery is broken or could it be a software problem?
Thanks for advices !
Sebastian
Maybe change a battery.
