Battery Marathon - Xperia Tablet Z General

I'm running on stock rooted KitKat with greenify and standby time on this device is quite long. I have done a lot of battery abuse in this tablet's lifetime. Played heavy games, drained battery fast, charging while playing heavy games for hours, charging all night. But still Sony is Sony

Very impressive. I'm currently on 7.1.1 with RR but my battery sucks, wich ROM are you using? And also are you using custom kernel?

I'm on stock KitKat. Which I think is the best ROM for this device. And there's no custom kernel. It's just rooted.

I think the whole thing is some kind of useless.
I mean, in sleep with everything turned off, i'm pretty sure tablet can last about a month with 3-4% of discharge a day.
But what's the thing in that?

Battery life of nexus 10 after updating to 4.3?

Guys, how long is your battery life now? Is it getting better?
I'm on my third cycle of charging after getting it recently. Updating it to 4.3 and rooted it too.
Current, the SOT is about 5 hours and I'm expecting it to be better.
Wifi connected all the day, mostly for browsing and so.
How about you guys? I've read a few with 11 hours SOT. That's amazing!

Funny you say that, my first charge after 4.3 I only got about 5 hours SOT. Since then it's got much better though, I rarely let the tablet get too empty on charge but I tend to use 50% of the charge (according to the battery meter) in about 3.5-4 hours. Ditching Chrome for AOSP browser helped my battery life a fair bit too I noticed.

Yeah, Chrome really hammers the crap out of the CPU. It's got a nice interface and syncing and all, but it's slower, less responsive to touch and uses more power than the AOSP browser...
My battery life is about 5 or 6 hours in 4.3, on stock rom and cyanogenmod :crying:
I went through two charges on 4.3. My battery life was awful, I'd get about 5 hours of SOT at minimal brightness. Flashed back to custom ROM/kernel and I'm back to 9-10 hrs.
Gonna wait for 4.3 to mature before flashing back. Nothing I would use was implemented anyway

What custom rom do you use? Gona give it a try.
My battery life is nice. I with moderate-heavy usage it's surviving from 8-10h . Running Stock Rooted Android 4.3 ROM
I only get about 5 hours too. I'm on stock rooted 4.3 with custom kernel. Thought kernel would help but not much... This sucks!

[Q] Stock LG vs. AOSP, CM ROM battery

Hello.
I noticed that on CM is battery drain faster than on stock LG rom. How is this possible if lg rom is bloated?
Has someone bettery battery life with aosp rom, or is LG always better?

It all comes down the the kernel for the most part, in this case, I have seen exceptional battery life with AICP - http://forum.xda-developers.com/showthread.php?t=2494700 -
It's been stellar, and has an unbelievable number of options. It has rebooted on me in a week all of twice, which is way acceptable in my book compared to the bloat and stuff that comes on the LG rom. I love the rom, tons of themes out there on the playstore for 10.2, etc.
I was wondering the same thing, if the battery was going to be better or worse on AOSP.
I've been debating what direction I was going to go with software on my phone AOSP or custom stock
So i tried CM M1 snapshot. Usage was same as with debloated stock LG rom. Sync on, wifi or internet on, some low brightness and some high brightness.
I think that even phone was used more with LG rom, for same period of time LG rom was at 78-80% and CM rom was at 69 %.
As you can see from screenshots, no wakelock on CM.
Second screen is display.
In my experience, lg rom giving me better battery life than cm.
I get 24 hours battery life with 5 hours SOT with LG rom, with cm I only get around 4 SOT

It s quite big difference. Hope that future roms and kernels will improve battery compare to stock.

Taking your battery to 69% after 18 hours with an hour screen on time is not an indication of anything other than great battery life for the first 18 HOURS!!
Then you DON'T post screen shots of the LG ROM and just say "I think" it was 10% higher and are upset?
At the rate you're going you'll be at 3 days with three hours screen on [email protected][email protected] - Now THAT was a scientific calculation!!
battery
For awhile i thought CM was better, but running the 11/7 version, it seems to be draining faster than stock
I haven't been particularly happy with my battery drain running AOSP (Cyanogen mod nightly at the moment) which is a pity because other than that it runs great.
What I've been doing is charging my phone up to 100% before going to bed then leaving it idle (connected to wifi) while monitoring it with BBS.
What I've found is it's draining at around 3-6%/hour. The strange thing is BBS shows that my phone is going into deep sleep mode so why the battery drain, possibly powermanagerservice wakelocks?
...
I made second test. Tried to use CM and stock ROM in same way (browsing, fb, some videos, calls, mails) plus I greeniefied some apps and some system apps and with same screen time I have result 84% stock rom for 1:20 screen time and 70% for same screen time in CM M1 snapshot.
On both screen was mostly at 0%, sometimes about 30-40% .
Honestly, can´t find any explanation why CM drains more battery, every post or article just said that it was wakelock or that CM just drains more battery.

Bad stand by time / Doze not working

Hi
I got my XT1572 a month ago and I like it alot!
However the stand by time is the worst and I dont know why...I thought that after updating to MM it would be amazing thanks to Doze but I dont know why it is not working at all
Even when I dont touch my phone at all at night for 8 hours the battery drops by 15%-20%...
I hope that you have a solution for me.
I have done a few factory resets...
Thanks a lot guys
Check your settings.. You might have a couple of things running in the background that are draining your battery. I maybe lose about 2 to 3 percent. If you are rooted check out an app called naptime by Francisco Franco. It allows your phone to go into doze mode faster.
I'm used to 90-92% deep sleep on my previous phones with custom ROM's.
But either Marshmallow isn't that good yet or our custom MM ROM's just aren't that good yet because I have yet to average higher than 83% deep sleep overnight on any of the CM or AOSP ROM's I've flashed so far.
I'm not too worried about it though, battery life is still lasting me all day and with quick charging, I have yet to be stranded without a phone.

which is sthe smoothest rom for battery life?

Hi, I didn't find a Q/A thread so I ask here.
I came from a rn4. I loved to use Los ext, it was one of the best rom for battery life. Now I am with miui 11 stock and debloated (I removed almost all ****), but still I m having a battery drain. In fact tonight it used 5% of battery in less than 8 hours with wifi and screen rotation only. I think it's too much!!
I red that some people can last their android battery up to 3 days with 4 hours sot, and I was stupified.
So which is the best rom at the moment for rn7, looking at: stability, smoothness, battery life, gaming, customization?
Does Mi app like themes, fonts, etc are removed normally in roms, and if yes, do developer create their own menu in setting for these things?
Who is using the Rom that will suggest me, which SOT you get and how much battery drain do you have in 8hours sleeping time with wifi only?
Thank you a lot! ?
When system running ok i got always the same sot on each rom i tested.
Stock Global, xiaomi.eu 10 and 11, pixelex 9+ and LOS16.
in each rom i mostly get 2 days with 6-7 h SOT.
battery drain over night in flight mode only 1-2%.
no big differences in the Roms for me.

That is still way too much for such a big battery ESPECIALLY in Airplane mode. It should NOT drain a single % of battery during more than 12h of idle, where as right now it can hit up to 10% for me, which is just unacceptable
For me, my phone doesn't lose any single percent of battery in 12h, in airplane mode

There are actually massive differences... IMHO one of the best ROM's is not even on XDA. https://os.revtechs.me
after a new install of LOS 16......
last 2 nights in airplane mode i didnt lost any percent.
first complete akku charce i got easyly 8h+ SOT
maybe old install was faulty....

HI, are you using some of them? How much sot?
It seems that rooting and using Roms on this phone is pretty useless on the battery side, because nobody talks about 9-11 hours of sot using roms.

Rooting is absolutely no problem and who ever presumes having 9-11 SOT is simply hallucinating... 7-8h is realistic... I don't even want to imagine how sad individual lives are being staring at a phone 8h out of a 24h day...

A good stable rom for battery backup?

Hi all
I thought I'd ask the experts about what are in your opinion some good roms for battery backup?
I'm currently on stock MIUI Global 11.0.5.0 (PFGMIXM) but I'm not much satisfied with the battery backup (5-6hours SOT).
I need some stable firmware since I use my phone mostly for work, no gaming, no social media, just phone calls, messaging and some light youtube usage.
Thanks!
Ion OS is brilliant, especially for battery - sourceforge.net/projects/i-o-n/files/device/xiaomi/lavender/ Around 10-11 hours SOT.
Anyone can compare MIUI vs Xiaomi.eu VS Pixel?

Miui right now just being laggy and jerky sometimes with animation, thus pixel based cutom rom just some having like miui and some is dont. I prefer evolution x on latest build, which smooth operation per my multitasking usage(on stock kernel obviously), whilst the battery just doing better other than resurection remix, pixel experience etc.

Could you be more specific about how long the battery lasts, I mean that if you are using your phone for like 4-5 days then 5-6h of SOT is quite normal for this phone but if you meant just one day then it should be about 10-11h of SOT as there will be less energy consumed by things like cellural network.
I had pretty good battery backup with POSP by AmulayaX but i found out that slow-motion isn't working so i switched to StagOS (unofficial EAS by Jimgsey) and i like this rom but i have some small issues and i consider switching to official.

5-6h SOT in 2 days. I'm not playing games I only use my phone for calls, whatsapp, emails and web navigation.
I'm on dual sim though.
I could never achieve 10h SOT in stock. Any hints for some good rom that can do that?
Thanks

Someone already suggested you to try Ion Official for Redmi Note 7 as it is EAS & feature rich also. But for more you can try Bliss ROM as well. Last but not the least LineageOS 17.1 Official. I'm currently using Bliss ROM. It is the best in all others upto now i have tried.

U can't reach 10 h SOT by 2 days on battery.
Calculate 0,5 %/h idle drain
2 days 48h - 5 hours Active drain = 43 h idle time
43 x 0,5 = 21,5 %
so round about 20% battery is lost in idle time
so 80 % for active drain.
Charging battery at 15%
80-15 = 60% left for active drain
On mostly all roms i tested i get an active drain by 10% per hour
Wud be for u 6 hours SOT
Seems normal drain with ur MIUI
But aosp roms are so much faster and mutitasking so much better compared to MIUI.
I only got 3 GB model and there no way back to MIUI
I gave PixelE+ a try but I'm experiencing less battery backup than stock (and some random freezes too).
I'll try ION or Xiaomi.eu in the coming days.
Meanwhile what about changing kernel? Any good recommendations please?

for me changing kernel isnt a game changer
its all about SOT, screen brightness for sure and good working deep sleep.
Screen is biggest power consumer.
Kernel maybe change covernor and undervolt cpu. sure this brings a lil power. but trust me it makes just a very lil differece. u cant compare ur drain because ur usage isnt same.
if wanna judge a kernels power consumtion u have to do all the same.
watching 2 hours youtube, play same game aso with same screen brightness with same wifi state aso.
i bet theres no "big" difference.

I'm currently on Pixel and I can make 4h SOT in 2 days. I don't play games or use YouTube. Just phone calls, whatsapp, browser, emails and I'm always on dual sim.
With stock MIUI I used to reach 5-6h SOT in 2 days so with my personal usage Pixel is worse in battery life compared to stock MIUI.
I'm thinking of trying something like Xiaomi.EU now since it's based on MIUI stock...
As i say, for me there are just few differences in battery life from rom to rom.
Miui is slow and bloated compared to non miui based custom rom.
When u just installed new rom u have more drain cause of trying out the rom. U have more usage compared to ur old rom. Lets get rom settle for a while before judge.
At least all rom take power. All rom need display. I think display always takes same power in every rom when u got same brightness.
At home in ur wlan mostly watching YouTube u get better battery (maybe under 8% per hour drain maybe less) than navigating in the sun with mobile data (cost 12% per hourand more) battery

I'm with you however I'm currently on Xiaomi.eu 11 (debloated) and battery backup is much better than Pixel. I hit 6h SOT on the first run, expected to improve in the coming days after a few charging cycles.
Same usage, the exact same apps running.
