[Q] Could new radio with 4.2.2 cause battery problem?

I have very bad battery life since 4.2.2. Trying to understand why that happens. I had around 3.5-4 hours SOT in 13-14 hours total usage which is very fine for me. I don't have very good reception, I know this drains battery but I'm living in same place so reception is still the same. Tried most of the roms and kernels. Flashed everything to stock 4.2.2 manually too but now the most battery life I can see is 2-2.5 hours SOT in 7-8 hours total. This is terrible compared to people at forums. Especially my screen started to eat battery too much, consumes %10 of battery in 25 mins. Even if I don't run nothing, don't use cpu, just kept cpu at 384mhz and screen on to test. I don't know much about these things but started to think 4.2.2 radio may have problem with me. Is that possible? Or what should I do? I will be really appreciate with your comments.

No. It's fine. Update the baseband if you choose to.

[Q] 4.2.2-4.3 battery difference?

Before, while running 4.2.2, usually cm10, i had been getting just barely over 3 hours sot, so not bad, it was acceptable for me. Now, after flashing 4.3 roms, and the new bootloader, Im struggling to get even 2 hours sot, even with lighter than normal usage. After going to 4.3, if i flash back to 4.2.2 roms, I now still get the same awful battery life. Generally, to go along with the 2 & 3 hours sot, my total time off charger is between 8-10 hours off charger.
My question is does anyone else have the same big difference? Could it have been the new bootloader and any new firmware i may have flashed along with it?
With how i spend my day, (I play Junior Hockey), up about 8am, light texting, snapchat, Instagram, while connected to WiFi, then about the same usage until about 6pm, keeping light usage, i drain completely with 2 hours sot.

Try calibrating the battery, go to the play store and download an app called battery recalibration, follow the instructions in the app, and you should be good. I noticed a definite increase in battery life from 4.2.2-4.3 so, you should be fine.

My battery life is very poor

Can anybody help me? I've spent hours tweaking and tuning my phone but my battery life is still terrible. I've frozen pretty much every bloat were, disable Google apps, low screen not bright, and using custom kernel and in it. D script. Can someone plz point me in right direction to have excellent battery life?

U call this bad battery life? Are u kidding me? I'll be lucky if i get 4 hrs SOT. Worry no more cuz, u have no problem.

Just wtf... Other than that, there are numerous threads about battery life. Don't be lazy, do some searching.

I combed the forums and Google but could not find good answers. I hear some people get up to 9 hours of SOT and I feel like my battery is poor because I have difficulty achieving 7 hours.

@justinxfan
That you couldn't find them doesn't mean they don't exist.

LOL! 6 hours SoT is great, if you could hit 7 hours that's excellent.
Those who achieve 9 hours do quite a lot of things. They set everything to blackish/darker background, they undervolt the CPU and probably GPU too, then there are other battery friendly Xposed modules are being used, like Amplify, Greenify, Power Nap etc. If you want to do those many things, then go on. I absolutely have no time, and more importantly no interest in wasting hours to achieve an hour or so extra.
You are on KitKat by the way, I have never managed to get any more than 5 hours SoT on KK, have hit 6 hours on LP thogh, quite a lot of times, and even hit 7 hours few months ago, I don't even check how much SoT I am getting as an average now.

how can i get this? i am on stock rooted. removed all the samsung stuff, using greenify. but cant get more than 4 hours on screen on time

Maybe because you're in a zone where reception isn't great? Poor signal is a huge culprit for battery life. Or probably you use 3G/LTE more than you use Wi-Fi. Wi-Fi sucks battery much less than 3G. There are quite a lot of factors here, you just use the phone normally, do not install any stupid apps, you should be able to get 5 hours SoT. 4 hours isn't really that bad anyway.

yes may be the reception isnt that good, i use only 2g.
i charged my note 3 n900 afetr 58 hours and the battery was at 25% and screen on time was 3h40m

Actually I'm using jelly bean I downgraded my phone to jelly Bean from lollipop after lollipop became too much for me.

This is great battery life you get. If you still want more, either turn your phone off, or downgrade it another notch to 3310. The battery will last a whole week.

Battery Life on G900F

So guys sorry if this post is "usual". But I bought the S5 for about 2-3 weeks now from second hand, also bought a brand new battery and I have remained on Alexander Devbase CPD7(MM 6.0.1) these days. My question is...how do people actually get 5-6h of sot on this phone? My best score was 3:46h of sot. Please give your app usages and tips. Oh and welcome me since I'm new to the s5 community Cheers.

Welcome lol
Nothing special, I just run a debloated stock ROM, 50% brightness is the only thing I change, WiFi is enabled 24/7
I was just showing my battery life with the new OTA 6.0.1 firmware earlier, over 4 hours with 50% battery left

All depends what you're doing on your phone though, if you're using that battery hog facebook app, or even have it installed, it's gonna drain your battery much quicker, or playing games etc
I use mine for WhatsApp, emails, texts and calls mainly, some browsing and easily get 6 hours SoT, today I was headed for 8 hours but forgot and plugged it in at 35%

Thinking about rooting

I have always rooted my phones but so far I haven't rooted my S7 Edge yet. However, the battery life sucks but after reading some comments on here it seems that people who root are getting no better or worse battery life. I was just looking for some feedback from people that have rooted to see what the majority response is. I've been contemplating doing this now for several days.
Thanks.

I've been contemplating about trying root again too, and that's after being on the U firmware. I'm now suffering battery life by only getting 2 hours of SOT by 50%, unlike at the beginning I could get up to 3 hours by 50%.
When I was on root though, that's how bad I suffered, only getting 2 hours of SOT by 50%. My Xperia Z3v is abandoned on support, but could still achieve better battery life being only on Lollipop. C'mon Samsung...

When i rooted my battery life dropped from 2 days to under a day before dying.

I am barely even getting that. I am at 59% right now with 37 minutes SOT and off the battery for 8 hours and 26 minutes. When I check app usage, the only thing that is high is the Android System at 39% and the Kernel at 10.7%. I can't figure out what kills my battery. I am on WiFi most of the time while at work or at home. BT is off as well.

On root you are using the engineering bootloader so the battery life is bad. You are better off using stock U. It runs smooth and battery life is not bad, plus you can get OTA updates.

U is a great FW so far. Battery life for me, with about 4 hours of SOT got me to about 50% at 530pm and I was off the charger at 7am.
