Battery drain - Xperia Z2 Q&A, Help & Troubleshooting

So I recently updated to 402 firmware but was forced to downgrade back to 55 cause of severe battery drain and now back on 55 (after a clean install) the problem persists. I haven't installed anything yet and this is what my stats look like constantly

Note: Facebook is disabled... Lol and the name of the process that appears in the icon is: ANT HAL Service. I have no idea to check what's causing this since I'm not rooted. Anyone an idea?

Alright after countless restarts and force closing of potential apps that could be draining battery I managed so somehow make screen disappear completely from battery stats. I'm gonna reflash firmware cause this is kinda bull****. I've never had such issues before 4.4 and I'm getting the impression that there's quite a few issues with it so far..
Update: after reflashing a clean rom 2nd time in a row I still can't get screen to register in battery usage :S
Anyone got tips for me? I'm this close to going back to the store and getting a replacement.

Do a full wipe and see if issues are resolved.

Didn't work, got a new device today anyway. This one came with 402 and has no issues whatsoever.

Mine too, but not so munch. 5% per night. Heavy widget and home screen installed.

I ordered a spare batt and now when i try to put the original one back in the phone does not boot unless i plug the charger in first then it works as normal. So every time i take the batt out i have to plug it in to the wall before i can use it? Pretty much destroys the point in why i got a spare battery

I dont know whats happening but provide the following details and someone here might be able to help.
- which ROM are you using? If stock then which region?
- since when did you start getting this problem?
- did this issue arise after you installed any application?
- did you always used the official smassung charger and battery?
Phone signal is draining out.. not to be negative but looks like you going to have a huge bill this month.

Looks like your phone crashed or froze during a period so it couldn't read the battery statistics.
Stock 2.3.4 from south east england always used default charger, not installed any new apps for weeks now. Happend after a crash followed by automatic restart. Random.

I'm currently using Darkside 3.2.0, faux latest kernel...
10% over 7 hours, ~1.5% per hour, looks like good battery life to me?

Thats exactly what I was thinking
Don't be concerned about wake locks if you get awesome battery life

are your radios updated ?

First of all thanks for the replies.
I know its not the worse possible battery drain, however data was off last night as I wanted to c if my phone actually goes to sleep.
my other android phone drained maybe 2% overnight with data off, so 10% seems a lot to me...
I have an international ATRIX and m using the latest radio (100.00 something like this) and no matter which rom I flash (aura cm7, and now darkside) the phone just stays awake.
With light use it lasts a day, but ideally 2 days is what im looking for!
Thanks for reading guys

[Q] is this a battery issue? or...

I have been having this problem with multiple roms. When my phone crashes and boots sometimes it comes up and tells me to connect to my charger and the battery is at less than 5%. If I reboot it, it comes back up normal. sometimes I have to reseat the battery.
I cleaned the battery connection and I haven't had any trouble yet.. but I haven't had any crashes since then either. I bought my phone on day one so I guess it could just be a bad battery? Anyone else seen this? In the pic you can see it happened twice.

Bro, there are a lot of better ways to rack up your post count then spamming multiple threads with "Thanks you!"...
Anyways Dr.Stainedglove, I remember someone with a similar issue a while back. Turned out to be a battery issue. Not sure if that's what caused your issue but if the phone starts acting up again I would suggest you look into a new battery. You can get a 1800mAh batteries (400mAh bigger then our stock batteries) for pretty cheap. See here.
Sure looks like it

Thanks.. I may end up getting one of those epic batteries even if I dont have anymore issues. Since cleaning the connections its been working fine.

[Q] Battery Life after 4,3

I've had my S4 since July and my battery would always last me until at least 8pm every night without needing a charge. Since 4.3 dropped and I've updated to it my battery life has gone to complete crap. I've used all the wakelock apps and none of them show anything out of the ordinary so I thought it was OS related and did a factory reset. That didn't work so I ordered a new battery from Amazon and gave it a 100% charge and this is what it looks like.

I've read countless threads of people with bad battery after update but not one of them has a solution. Should I do another factory reset since I got a new battery? Keep in mind I can't root this phone because it was given to me from Samsung for work so that is out of the question.
I ordered this one because a friend of mine has it and he hasn't had any issues with it so I figured I'd give it a shot http://www.amazon.com/RAVPower-SGH-...TF8&qid=1391625055&sr=8-2&keywords=s4+battery
So maybe try another reset/clear cache with the new battery?
I use anker batteries and I think they're great. If you ever thought of trying another one give one of those a shot.

The problem isn't batteries though because it started happening when using my regular oem battery.
Oh I know I was just throwing that out there

Galaxy S4 I337 Phone package causing inordinate battery drain.

Hello there,
I've noticed in the past couple of days that my phone's battery has been draining like a sieve. I popped into GSAM and found that my phone package is eating 50% of my total power usage. I've had this issue before with Android System and stuff, but that seemed to fix itself.
I've tried a soft reset to clear any memory issues, but that hasn't done a thing, I've lost 30% battery in an hour.
Any advice on how to fix this?

Thanks a bunch!

Try flashing the stock rom with Odin, probably something is corrupted in the phone app
