[Q] battery life experience on different rom

lately i have expereiced that aosp battery life is not better
stock rom has way better i had like 11 hours screen time with very little wifi and gps usage
please i have been flashing aosp and tochwiz roms lately and even kernels but iam not able to get required normal attery life
please share ur battery life tips and the rom and kernel ur using with
there should be a general thread about battery life tips what i noticed that note 2 might be the phone with custom roms worse battery life compared to stock
ive used greenify and just use my phone for chrome messages and call
please share good stasts and tips
there should be rom reviews by users about battery and stuff so people can know,its too much time consuming trying every rom and setting it up and in the end replaccing it
please its a request to all users
help other community members thanks

I've been using greenify and rescan media root for a while and I can notice the difference in battery life.

Battery life is normally driven by your kernel. However, chips are mass manufactured and as such are not identical. So what works well for me and my chip may not be brilliant for you.
Imo the only thing you can safely compare, regarding battery life, between two handsets is screen off time. The best I've experienced is 1% drain per hour. to get that I use jedix20 rom with the built in saber kernel.

Yes AOSP has weaker battery life.... just use 4.1.2 ROM for now, and wait for official 4.3

No that drain is with screen off.
I understand your desire to get a 'league table' of roms/kernels to compare loss etc. However, I've seen people in these threads turn all power sappers off like wifi, mobile etc then leave the screen on on a dark picture just so they can say they've had 2 days of screen on time.
Would that really be real life use and helpful to anyone?
I play asphalt 8 and when I do my battery drains super quick maybe more than 20% an hour. Yet if I'm only Web surfing that 20% would last maybe 5 times longer. So how could you successfully compare that kind of usage?
That's why I think the only real safe comparison is to compare standby time with the screen off. Btw i leave my wifi permanently on.

Getting about 30 hours + 5 hour screen time + 1 hour Voice calls on 2G
Can get pretty must 24+5hr scr with 3G too
But my main concern is , It does'nt handles the Radio very well , While Signal fluctuates or I'm on the move, battery drain is heavy , When i'm in good reception area without much movement then it does well. I don't know why. Sammy handles this much much better may'be the issue is with Radio/sensors/GPS drivers.

without use, or better saying, 1h of music each day, plus standby about 23h, my battery lasts about 1 day. but i've already did it last less than 4h, with wifi, gps, 3g and everything else on. disable things that you don't need, battery will last a lot longer, doesn't matter the rom. there's no miracle to be done, with thin batteries. to last longer, batteries require to be bigger, it's more than logic this, but people today asks for an portable pc, vapor as battery and lasting longer, it's impossible to do that. but still, you can have an power bank, replace your battery for an new one, but that's it. still, in config, performance, processor, cpu manager, you can set "power save" and check "set on boot". battery will last longer, but your phone will become painfully slow

About heating I can't be of help because I dislike computer gaming, about custom ROM on this particular device which was born for just specific countries, on particular I'm referring to Chinese version, I think that it worth to flash to obtain a more tailored system. About the purchase today I will opt for a newer device since zuk z2 it's not the latest and as you probably know technology runs very fast.

I have this device since 2months and I never had any overheating issues. But if you don't want to flash a custom rom, then I will recommend you to buy a xiaomi, you can maybe wait 2 months and buy the redmi 5

ok then i think its better to move towards another brand

The best bet would be to purchase the phone and use it as much as you can and burn the phone ASAP and claim your warranty in this way there will be a lot of trouble for Lenovo Customer Services, and if they see this issue then only their developers will take steps to ensure optimum customization & performance with no heating solution.
This Mobile is at its EOL and that is the only purpose the mobile prices are reduced so much in India, Lenovo is looking forward with its MOTO brand and leaving behind its ZUK brand.
If you really don't care about warranty just download the unlock bootloader file and use your choice of ROM, and even if there is some damage, just revert back to original stock rom and claim your warranty.
But the best bet would be to continue @ the stock ROM and if the heating issue persists just try to burn the phone, in this way your are legally good to go and you can claim your warranty.

#1 - 3/32 version - don't buy, 4/64 version - yes
#2 - no
#3 - somewhat.. but now I am on custom rom, there is no heating
#4 - if you can't or don't want to install custom rom, yes go for another.... and best at this range only one phone is there - xiaomi note 4
But I will still rate this phone better than that... Because of size and it never hanged..

thanks for ur valuable opinions...

1. What custom ROM are you using?
2. Does that ROM have built in scheduled power on/of feature?

I know this review doesn't even matter anymore because you should have already purchased a new phone. And with the device being outdated and the company shut down.. This is meaningless, yet I wrote this because phone is still selling quite nicely in my country(India) and some new users can use this review.
1) There's no heating issue unless the phone is used for gaming for a quite duration like 1 hour continuously. But that's natural right ?
2) The heating issue shows up in Summer.
Just a day before I wrote this review, my room temperature was 38 Degree Celcius and phone started lagging even when I watched just a single youtube video. I Thought I must be dreaming. SD 820 and lag ? Even decided to take a stupid step and checked Antutu scores (as I knew they will drop when heating occurs) And Surprise ! The Score was 53K ? I reset the phone thinking that Rom might be misbehaving as this is my 1st device that I haven't reset in 2.5 months. Again with an Antutu test I get 85K ?
So this is just atmospheric heat. My guess was just that to keep the costs low, they might have used the low quality materials. But who knows ? I'm not aware much about heat dissipation system used in Z2.
Conclusion : If you're a heavy gamer, don't go for this phone. Plus my review is based on Stock Rom. I haven't yet void my warranty. ? Custom Rom might even be different but Hardware issues wouldn't be solved that easily.. An average user can go for this phone with eyes closed. You won't get such an astonishing SoC at this price.
Verdict : I used phones like LG G3 Beat and Samsung Galaxy S5 before this one. I feel that touchscreen on this phone isn't as smooth as the other phones. Even mid or low-ranged Oppo and Xiaomi have better touch response. Again I might be wrong as I haven't used Custom ROM yet. But I'll update this review for sure after using custom ROMs on this phone. Would hardly take 1-2 months. ?

Hi! Any Updates?

New Battery

ssss

tetanus444 said:
Hi, I would like to ask if it is possible to get a NEW battery for Lenovo K5 Plus (about the Lenovo BL259 battery type).
New ... I mean the newly made in 2018.
I dont need a new battery urgently, but I would like to buy a new one in a while.
The current battery is good but I would like to buy a new battery over time (I charge up to max cca 85% always, I dont discharge to full discharge etc.).
Maybe someone has already solved something like this, like a question about an official producer, good shop etc.

Well you might be a little bit crazy with the battery thing.
The phone is from Februrary 2016, you might bought it even after that.
The battery life may decreased a little bit over time, but after 2 years not a lot, you might buy one from Ebay:
https://www.ebay.com/itm/Battery-BL...223065?hash=item3d4eedf699:g:zbgAAOSwbF1aCAkB
Well yeah it's from China but should work fine.
If you think you might have big battery drains that could be from the Rom itself, and you may install an custom Kernel like this one to help with that: https://forum.xda-developers.com/k5-plus/development/kernel-t3725978
Or you might change the Rom with one that doesen't drain that much.

Q : i Got Confused ! .

i have a small question to whom ever tried custom roms for Mi Max hydrogen,
i have my brother phone and he need a new tested rom except ( MIUI ) , i already looked for him here but its a bit confusing ,
to many uncompleted & unstable roms here which need enhancement and some still need fixing ,, any one can give me a single rom that is 100% tested Stable and have no sound quality issues ? and the most important is fast-charging and in-Call volume Quality ! .
Thanks ! ..

and incase any one asked , yes i got retired already , no more Dev. just a google'r .

Yes you can try linage os ROM which gives more performance than any other ROM but not more customization and but from my side I specially recommend you to take aosp extended ROM everything works excellent except casting and you can trigger fast charging in kernal audiutor but it can make your battery hotter .

Thanks bahai ! , any more thoughts Guys ? its not mine , for my bro so i don't wanna get annoyed after all
