So I just flash the PAC rom for my Samsung galaxy s5. So far everything is working for me. But I noticed that my battery is getting low very fast after installing the PAC rom. I have Bluetooth, GPS, Wifi, Mobile data, and phone serviceon at all times. When I was on Stock rom it would take a day and a half for the battery to get low. Cyanogenmod took about a day but I had no phone service to drain the battery. With the PAC rom, it takes 4 hours for the battery to drain. I have also noticed that the phone is getting very hot while I am using it. When the phone is charging it gets a little warm. Is there anything I could do to fix this? I am not sure if maybe I did Something wrong.

Battery calibration, galaxy tab 2 CM9CM9, and at first glance it seemed that the battery was draining way too fast.
So after some research, I found a solution to this problem. When I had the stock rom, the battery life was like 15 hours, all day wifi on. But when I moved to cyanogenmod 9, the battery life dropped drastically to about 6 hours, minimum brightness levels. So got back to stock. Soon I was missing CM9
Suddenly came to my mind that maybe the problem wasn't CM9, since I have read that many people is very happy with battery endurance.
When we flash a new from, the battery data remains intact, this sometimes causes the new rom to have a bad reading of the stats.
The solution I found is battery calibration. You can find an app for free in the market. What it does is, it wipes your battery data so the new rom generates fresh data.
You just have to get your GT2 fully charged, then calibrate with the app.
Since I did this, I feel battery life has improved, in fact, I think it is better than before CM9.
YOU SHOULD GIVE IT A TRY.
it worked fine for me. :laugh:
sorry
The post was right before sending it.
Tried to attach a pic, but I'm new here guys
Battery calibrate only deletes the existing battery usage data. It gives you a fresh look at what is draining your battery. This has been argued many times in just about every other device forum. Here is the answer from the google rep.

:good:
I don't know if I'm the only one who's noticing this but I just came off 4.3 TouchWiz onto SlimKat 4.4.2 (Build 5) and I'm noticing battery drain like crazy on my mobile. I thought it was bad on my previous stock ROM after the horrendous 4.3 update Samsung provided but this is worse. I used to get around 9-10 hours of battery life which has been reduced to around 6-7 hours now (I know it's not a HUGE difference but I'm not a fan of charging my phone twice a day). Overnight (despite leaving it on flight mode) the battery of my phone drops by 8 odd % in around 6-7 hours. Does anyone know the cause of this and can someone please help me?
Thanks

With the above, I get 1+ day of battery on my i9300.
Read in other forums of other ROMs with 4.4.2 that battery drains with this KitKat version
Using omni ROM 4.4.2 battery drains on this too. Could it be Version specific problem ?
Hi, i would know which rom has the best battery life for the i9505.
I'm currently on DanVDH 5.0 Lollipop rom, which is awesome but the battery life isn't that good : With only wifi on, airplane mode on, brightness between 30-50%, and normal use (Chrome, sociak networks, some dl and videos), i can't get more than barely 3h30 of screen on time, sometimes 4 hours but not so often.
So, which rom (and maybe kernel) would you recommend ? I'd love to get at least 4 to 5 hours of screen-on time.
Im using the CM12 Lollipop 5.0.2 Build from Antares and got between 4-6h Screentime, without problems any way more usage as you.
Maybe your battery is ... dying?
It can't be the battery dying, it's a S4 black edition which isn't old.. And in stock rom it used to last way much longer :/
I have a Sprint Galaxy S5 running MOAR ROM and Ktoonsez kernel and I started using an app that tracks screen time and I've noticed I only get about 2-3 hours of screentime on a full charge.
To me, this seems pretty awful and other people using Ktoonsez report having excellent battery life but this doesn't seem to be any better than stock ROM/kernel. There's also nothing abnormal on the battery settings screen. Is my battery drain abnormal and is there anything else I can do to improve it?
Does anybody know a ROM that has a battery life that could last me the whole day, by the end of the day like 40% or similar? I'm using Graviton ROM and while it works, the use of resources isn't very wisely used and by the end of the day I would have 20%. I use my phone constantly only for web browsing, phone calls and messaging. I don't play games or anything of that sort. I have an AT&T Samsung Galaxy S4 running 4.4.2 with baseband NB1.
Goldeneye v53 on 5.0.1 user here, I get about 12 hours of life with about 4 hours screen on time.
Just use Greenify. Or flash an AOSP ROM. A LP ROM will be HORRIBLE battery life
