[Q] Galaxy S3 batter drain issues

Recently I've been experiencing battery drain issues which hasn't occurred before. When I first got the phone I can go through the day with about 60% of the battery left at around 11pm when I plug it in, but now I have to plug it in at around 8, with 5% battery left. At the moment I'm using omega v43.2, I don't think its the rom's problem because I've tried switching roms and it didn't help.
Does anyone have a solution to this battery issue?
Thanks

[Q] weird battery meter issue?

I have a samsung galaxy young s6312, stock android 4.1.2 jellybean, rooted. Since a few days I have been facing an issue with my battery. When i charge my phone, then remove it from charging, suppose at 78%, then the phone stays at 78% for about 1 hr or so, even if I use it extensively, and then the battery level begins to descend sharply, within the next half hour, it will be at 50%. this issue came up recently, is it a problem with my battery or is it a software issue??

[Q] Problem with battery and speaker

Hello,
I have Samsung Galaxy S3, rooted, running on CyanogenMod 11 M12 Snapshot (cm-11-20141115-SNAPSHOT-M12-i9300) and i have two main problems.
1) Firstly, I have a problem with battery. My battery is charging and discharging very fast. I had this problem also on TouchWiz, but I thought this was a problem with system. Now my phone is charging really quickly (40% in 15 min) and discharging in about 4 h of using. I tried calibrating the battery by charging it to 100%, then I restarted my phone to check is it alright and it was, so i calibrated it with a Battery Calibration app from Google Play. Then I used Fast Discharge (as recommended) and I checked to use processor. After 5% of battery (95%) my phones screen turned white, there were weird sounds (like old TV without signal) and then it restarted. Battery was 25%. Now I'm charging it again, unfortunately it's again charging so quick.
Is it a problem with my phone or battery? My phone still on warranty, so I can make full fix from this forum and give it to Samsung.
2) I also have a problem with speaker. When using my phone I can hear weird sounds from it (like above - like old TV without signal). What to do? Can You help me?
Please, help me

Check if you have a swollen battery
try a replacement battery, the weird sounds and screen issues could be from the battery not supplying enough current/voltage to the phone, hence also an issue why it cant calibrate well

Galaxy s II - i9100 Cm 12.1 Battery Fast Discharge

yea so I got cm 12.1 installed on my phone. perfectly working. but I just noticed the battery discharges so fast. I got 100% charged battery but after 30 mins of usage, only 73% of battery is remaining. But I checked my battery status/usage on settings, but all of the apps are using only about 7% below of my battery. Last thing I noticed is that when I open up my wifi, every minute, battery drops. If I play games (wifi off) the battery isnt dropping that hard. But If I play with wifi on, it discharges dramatically. Is this thing connected with wifi things? how can I solve this ****ass thing.? please help:laugh::laugh::laugh::laugh::laugh::laugh:
