[Q] Is there an official Kitkat firmware with same battery life as Jelly Bean? - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hi all,
I am new here so I hope this is the correct place for this question.
I ordered the Z1c and expect it to be delivered any moment, I already went to most threads regarding KitKat on the Z1c.
For me, battery life is the main reason why I choose this phone. It appears that updating the firmware of Z1c to the current KitKat version results in a big loss in battery life (and apparently also quite some bugs). Of course, I would like to update but I am in doubt if the advantages of going to Kitkat makes up for the loss in battery life.
In that respect, I have the following questions:
- How bigg is the loss in battery life if I update to the current version (757 in Begium I think)?
- Which official build number of Kitkat has the best battery life?
- What are the main advantages of updating to KitKat?
Thanks in advance
Regards
Dries

I'm on 757 firmware and I don't notice any big difference between KitKat and JellyBean battery life. I also didn't notice any bugs yet. However I am not constantly using my phone and usually get a bit more than 2 days of battery life.

I agree. There is a slight difference between 4.3 and 4.4, but it's not big. Most people won't even notice that. So I wouldn't worry about updating to 4.4.

Hi Zxz, Martan,
All questions evaporated with arrival of the phone: it came with KitKat 4.4.2 build 757 installed on it so keeping Jelly Bean is simply not an option.
Battery life seems very acceptable: I used about 25% toying with the phone, checking e-mail and downloading updates for some apps using WiFi yesterday evening. Over night, it lost only a few % in Stamina-mode including waking me up twice.
All in all, very happy with this phone. Runs very smooth and up to now, no bugs encountered. I expect to get several days out of it on a single charge and that was the aim from the start.
thanks for your replies
Dries

Note 2 - is battery drain still an issue?

Hi folks, I'm considering buying a used Note 2, but I've read that the 4.3 update has had a negative effect on battery life. Has there been an update since 4.3 which has rectified the problem?
Anyone have an answer to this? I'd like to make a decision ASAP. :good:

I have used many different custom roms of JB and now KK. By freezing unused apps and hibernating user apps, I get a good battery life.
There are other factors you may need to consider, like the age of the phone since battery degrades through time.
I hope others can provide their opinion, goodluck.

Which ROM has the best battery life for you?

I want to start a poll and a discussion thread, also to help new users (and old users) to decide which ROM to use, if long battery life is the top priority in their choice of ROMs.
I myself have only used STOCK 4.1.2 JB, and STOCK 4.4.2 KK (E988), and I have tested both enough to convince myself that Stock 4.1.2 does have better standby battery life than stock kitkat.
But for the sake of greater completeness, I will include 2 more options in the poll: 4.4.2 Variants, and non-Kitkat Variants.
So based on your experience, which ROM has the best standby battery life for you?

In comparison to kk roms, I think stock jb is better in this regard. I would be curious to know how much better you found it in comparison to stock kk?

Based on battery monitor widget, I averaged 4.6%/hr drain on JB ROM, 6.9%/hr drain on KK ROM. Medium use through a typical day.
I'm getting decent battery on this kk that I've been using for the last four or five days.
People know I'm cynical about everything, and with that in mind, I think this Rom is better than others for battery life.
Unfortunately, Camera has stopped.

Yes but usually JBs have better battery life than KKs. (On the Note 2, this was much more obvious. And many of the custom KK have horrible battery life, both on the Note 2 and the OGP.)
I ran the stock JB on my phone and it was not too bad but this KK is somewhat better battery. I'm not saying that its mind blowing better, just a little bit.
The best battery life on any device I've ever held was the LG G2 running stock JB 4.1.2. Unbelievable.

Best Custom Rom for Stability and Battery

Hello,
What Custom Rom you guys think its best for Battery Life and Stability?
I've been using CM11 for the last few months and now im Trying Omnirom. They are both stable and use the same battery.
I cannot try every rom, so im asking here for your opinion.
I very much doubt battery life would be any different because of ROM version.
It has more to do with individual usage patterns
&
BT On/active/streaming
Brightness level/Auto
Data On/updates/push services
Calls talk time
Text/chat apps
Wi-Fi/Hotspot on/active
I'd say if your getting nearly 2h's of screen on time then the ROM is just fine.
There may be others getting more, but it all depends on how you use your device.
I don't mind charging my phone 2-3 times throughout the day(to help keep it topped up), I don't use Wi-Fi since I have unlimited data, unless it's for a large occasional download (testing new ROM/apps) have auto app updates and push services on) and leave BT on to automatically connect to my car stereo and start streaming music and also always leave auto brightness on.
Personally, I have tried lot's of different Custom Roms, and to be honest, none of them are as good as Stock 4.3 in terms of battery life and stability. Yes, other ROMs offer additional features and Android Versions that would otherwise be unavailable, but are mostly less stable, more laggy and have worse battery life. If you want customisation, you can root and use Xposed Framework.
That said!.. the best custom ROM that I have used is both FML Kitkat and FML Lollipop by MWisBest.

Recently I went back to 4.2.2 (Verizon) because no roms I could find had decent battery life. I started using greenify to help with memory, as I find that soon as it gets to about 100mb free, the lag is terrible.
So in your opinion FML Kitkat vs stock on battery is worse? I briefly tried FML Lolipop but felt it was too early in dev and buggy
thx,
riz

Yeah, I've always found that stock Jelly Bean has the best battery life. But your experiences may vary with usage.
I have used CM11, PA, Shiny ROM and FML so far. I cannot compare them to stock, since I haven't used stock due to lack of customization features.
IMO, Shiny ROM + Dirty V Kernel with Nephilim's settings had the best battery life. On standby, my phone ran for more than 2 days without a single charge. Performance was decent, although I wouldn't say that it was ideal.
I'm currently running on the latest FML Lollipop + Smitty L Kernel with Nephilim's settings. The battery life is decent, with about a day and a half standby time. Performance is fantastic. If you value both battery life AND performance, you might as well give this a try, as it is definitely worth the effort.

[Q] Pure Stock Kitkat VS Lollipop

Hey guys,
I wanna stay on stock Rom (without root) and I'm running now kitkat 4.4.4
Do I go for update or do I stay on kitkat? (Will performancmce be reduced and will battery llife be worst on 5.0.1?)

First of all, I would update. I'm enjoying Lolly myself. No performance problems, and batter life is as good or maybe better that Kit-Kat.
Second of all, What carrier/version are you running? If you have the OTA downloaded and not installed yet, it could be valuable to other users.
It's eu version. I heard that lot of users complain about lollipop battery drain...
that's why have I concerned

The problem with lollipop is that the kernel and system eat a lot of battery, or at least more than on kitkat. If battery life is your concern, I personally would not recommend going on lollipop till 5.1 hits and see if it's fixed
though how you use your phone will still make the biggest impact
That being said you can still get great battery. Usage for me never goes bellow 5 hours of screen time with games and 4g and around 7 hours without games and wifi. I could do better on kitkat but I'm satisfied. Check this thread for battery life. I enjoy lollipop though since I upgraded, but I can't wait for an update to 5.1 and better battery

I have had no problems with drain, whatsoever. I'm not stock though, but on the stock kernel.

Galaxy Nexux slow. Which ROM should I use to upgrade?

Hi,
My Galaxy Nexus 4.3, is quite slow and it has huge battery drain, even after a reset. So I was wondering to try an update to Marshmallow 6.0. Questions:
- I found many ROMS in this forum, but I have no idea which one would be the best for everyday use. Could you please recommend one of them?
- Make sense to try this update? The phone will be faster and it will consume less battery compared to 4.3?
- I have no experience in updating ROMS. Which will be the most simple procedure that I should follow in that case?
Many thanks in advance for your help!

I can recommend this ROM:
http://forum.xda-developers.com/galaxy-nexus/development/cyanogenmod-12-beta-builds-t2958865
It has official cyanogenmod nightly status and I use it as a daily driver for my GNex. It is stable and
I experienced an increased battery drain with older CM 11 (4-5% per hour in stand-by) and Google apps package installed so I removed Google Apps completely and never went back. Battery live was up to 2,5 days with normal use and up to 6 days in stand-by.
Running with the the above ROM my GNex again can reach up to 2,5 days with my normal usage and still have about 40% of battery left.
Normally I use my my GNex for listening to mp3s and reading news sites when commuting to/from work (about 2,5 hrs/day), in addition internet research back home using WiFi, plus regular phone calls and texting.
I do not use facebook, twitter or the likes and hardly ever watch youtube on my GNex (it's more fun in front of a real screen).
