Battery serious problem

hey guys,i have been flashingmany roms every week for about 2 months, then I decided to start fresh.
wiped every thing via cwm and then flashed stock rom via odin,then rooted it.
problem is battery is as fast as HELL , and i have sudden drops, e.g. phone shuts down suddenly at 30% or even 50% , and when i connect charger it shows 0%.
tried battery calibration but no good.
I bought a new battery , and my phone still have sudden shutdowns when used for more than 30 minutes.
even offline.
Is my phone damaged ,or it has permanent leak ,even i change batteries?!
plz reply ASAP , and btw i dont have a screenshot cuz i am using stock 2.3.6.

I recommend you to go to a Samsung Costumer Service and ask for help. I think is a hardware issue, not a software issue.
Also, to use screenshot on GB, use Volume down + Home button.

Must be hardware. If the battery change doesn't quite cut it, then its a hardware problem.

Battery improvement -

I just started using Dual SIM on my mobile and it seems battery consumption has doubled. I am on stock latest version.
Can people share their ways of saving battery apart from removing Samsung bloatware, rooting the phone !!

try under clocking!! download performance control and under clock whenever you fell you don't need heavy processor usgae till 1200....i know tha it changes by itself..but trust me its better when u do by urself!.....312MHz is enough when cell on stand by......call receiving and msgs work, though ui lags.....try battery saver apps....i never faced such issues as i did root on second day i bought my phone and third day i had pawitp 4.2.2 on my phone ..still ..give suggestion a try..hope it helps.

if you are rooted
install setcpu or no frills cpu and simply set cpu governor to on demand or conservative and underclock upto some extent if you want
this trick will surely help you buddy

My note II restates out of the blue without any good reasons :crying:
it generally happen when i play any game or use 2 or 3 apps at the same time ( like sound cloud , facebook and messenger )or ( game and messenger ) or playing for a long time ... knowing that the battery is fully charged or at least more then 80% ... it suddenly restarts with about 2 % .. and i take that battery out and in and open the phone to find it about 60%
i tried to factory reset
knowing that the phone on kitkat 4.4.2 the original french update from Samsung , and i tried also to run the secreat codes but neither of the code worked!!
can anyone please tell me what is the problem and how can i fix it please

how old is the battery?
did you overclock?
check if it's warm or even hot

the battery and the mobile are about 2 year ...
and no i didn't overclock the phone
and it gets a slightly warm in fact

battery life is approx. 1000 cycles, so in 2 years it is quite possible.
If you can swap battery and test. If you don't OC, then it's not a security restart.
I bet it's battery

i thought at the first it would be some kind of software problem ...
i'll try to get another battery and try it out
really appreciate your answer
thanks :good:

Weird coincidence. This started happening to me on May 10th. My 2.5 yr old phone would restart over and over even when plugged into the computer. I did a hard reset and it still didn't help.
I replaced the battery and it fixed it!

Problem Solved
it was really the battery
once i changed it every thing went back to normal .
thanks everyone for your answers :good:

Its also another weird coincidence as this issue has happened to me, my note 2 is also 2.5 years old and my phone kept restarting too, but i really didnt care much and instead, i continued to use it over and over and overclocked it to 1800 mhz and i have no idea how but is stopped restarting. It was weird, at least is saved me money buy not having to buy a new battery. But as i expected, a new problem arises, systemui keeps crashing. But the battery is still fine, all i did was flashed a new rom.

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?

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
