The battery doesn't work correctly... - Touch Cruise Android Development

my system is warmdonut , since yesterday my battery doesn't work well. The battery kept full(whole strip), and after about 6 hours ,it suddenly became empty. Why?
btw,my radio is 1.59.46.12

i get this at the beginning of a rom use but generally, things get better after
maybe because of a calibration

sorry for my English.
Hi chourmovs,
may i learn how calibrate the battery to improve it??
I am running Andriod by Haret, every time i see the battery rest around 50%, then will out of power very soon.

i'm not sure but my answer for nand will be
" Just use a recent kernel and wait for battery to autocalibrate, maybe 2 or 3 days of use"
i'm still not sure of the existence of this autocalibration process, that's just a personnal observation

Hey.
I had this problem too.
My load-display was half full when the device died. After a few tries its better now(~4cycles)
I think its important to load it from nearly zero to full(kinda hard when starting empty device via haret
or the way i did:
Load fully while device is totally off and let android suck it empty 100->0
......
But my device only lasts ~6h, most time standby. Maby while using haret? Could think of the sd-reader to suck the battery :/

WM6 KILLS the Battery... Help!!

I recently upgraded to WM6 ROM, "Jwrightmcps Crossbow ROM Update 2.02.02 WWE", and all went well.
But then at 40% battery my phone died... and this is very similar to a problem I used to had in WM5.
Can anyone tell me which WM6 ROM doesnt cause the battery problem?
For the record, I don't think either my phone or PDA is damaged. The last time I had this problem, I went back to the service center (several times I might add), and they replaced everything eventually (both PDA and Battery). Since then it has worked fine (for about 6mths+), until I flashed to the WM6 ROM.
**** man, I hope this has not damaged my device. Out of warranty already.
I had a similar problem and also initially didn't beleive it could be the battery, but guess what -- getting a new battery solved almost all problems I had including the phone dying at 40% or above. So it might be worth a try...
IT"S YOUR BATTERY
Just trust me
the battery 'dies' after like 6 to 12 months. It just goes bad in a week.
Mine went out on like 20%, then a week later on 54%
replacing it fixes it.
mine crashes over 20%.... the battery it's new
I had same problem with battery,then I buy new battery from ebay, and then the battery status was OK it goes from 100- 4% with warning and everything. But the problem was that battery last only a couple of hours, even aftzer a few days nothing change I must have charger with me all the time.
Then I search the forum and found someons solution, that works for me too.
Just charge the battery full take the cable out and put it in again a couple of times so the battery is realy full charged, the put the device in bootloader mode by pressing Power + Light + Reset, which brings up an un-backlit screen with "Serial" at the top, and "v0.XX" at the bottom. And then just put your device somewhere and dont touch it until it died that coul be the all day. Anyway next day I put the charger in and again didnt touc for all day. And my problems are gone, the battery since then last fortwo or three days if I dont use it much.
Hope that will help somebody
Dears,
i used to read about this issue in the forum again and again.....so i desided to wrote this post....everyone was claming the battery is the reason....OK do not belive this.....it is the rom.....i used the wm6 for sometime and i was facing the same problem....and when my carrier started the 3G i had to switch back to wm5.....and now my device never turns off before i get notified that my battery level is too low it about 10% of the battery....so if you do not belive me just do this test....switch back to wm5...i am using now Hilme 3.5 v1.3.1
regards
Mine dies at 35% with wm6 and wm5 and my old battery, but never dies with my new battery.
Use Radio 1.15
My battery life increased by 200% just by upgrading to this radio ROM.
same here
i m also sufrer of same problem. now after this forum i m confused
Here is the simple fact of the matter:
Batteries are EXTREMELY complicated pieces of equipment
They often give false readings because the chemical reaction that creates the electricity is easily affected by heat\age\use\etc. Also, the electronics that measure the temperature are based on the false assumption that the battery drains in a predictable way down to the same level.
Your battery draining quicker\slower and dying when it says it has charge may be because of the ROM. However, this is HIGHLY unlikely. What is most likely the cause is external factors (eg heat, number of programs running, etc) or that the battery has "died" or become unreliable.
Recommendation: Try different batteries, and remember that batteries have a chemical reaction, before posting here
I don't know... I started having problems as well just after a ROM upgrade... but it was an official ROM upgrade. I start thinking this has something to do with the upgrade process, like some setting being "wiped out" during the upgrade and the battery going "out of sync" with the device, reporting the wrong battery level...
But, more likely, this is just a psycological effect, you install the new rom and then start playing a lot with the device to find the improvements, and you begin noticing the problem for the first time!
My relatively new I-mate JasJar also started dying when the battery level reached 40% the day i flashed WM6.
i posted here, trying to explain that it was perfectly alright 2 days back, prior to WM6.. pointless to say, everyone still said it was the battery 100%
well.. i got a new battery.. and it did indeed solve the problem.
but guess what.
i flashed WM5 back, and both batteries work fine there.
not sure what the heck is going on here.. but i'm certain there are two fixes:
- flash WM5 back on.
- get a new battery and stay with WM6

I used to think like you, but now I beg to differ, my dead battery never usable under any OS.
It used to be always dead at some % starting from as low as 0 (good ones) and increase until now it is permanent dead at 100%. I have all your intermediate voltages before reaching 100%.
If your's still usable than your battery is not complete dead yet or half dead or maybe soon to be dead.
By the way, I am using helmi_c aku3.5 v1.3 (add on version) as compared to v1.3.1 (vanilla version).
One last thing, please do use big bold characters in forum, sounds like shouting. Thanks!
You cannot judge the battery is old or new by just months.
This older version of Universal battery, it counts by number of time charged I think, inserting in USB for a sync and remove would probably counted as 1 charge.
I now do not sync using those working condition battery, I change to my dead battery for sync purpose.
As I sync only contacts, now Dotfred has a tool and now I hardly use sync anymore.
By the way, there is one guy in this same forum start another thread without reading this (closest info) or all other previous threads.
People like this deserved to be flamed, but I didnt.
IMHO WM6 uses and drains the battery different then WM5
My experience is that everyone that has problems with their device dying just switched to WM6. It has nothing to do with the WM6 itself, it's just that WM6 is more 'sensitive' to a low battery output then WM5. So if you switch back to WM5 it looks like it might 'solve' your problem but in the end the battery will die, it'll just take a little bit longer before WM5 appears to have problems.
You'll postpone the problem for a little while but it's not a fix
Just my 2 cents

Mine still working very good at WM5 as i told you.....just let the battery get off and recharge it till full....now mine is working great and keep working until 10% or less
The point is that WM6 treets the battery and power in different way then WM5. First when you upgrade to wm6 and start it first time it assumes that battery is full (the instruction says that you should charge your battery before uploding new ROM). If the battery was not fully charged then you have a problem. WM6 registers the point of current while starting first time and assumes that this level represents the fully charged batteryl. Then it is programmed for consumption of power according to processor cycles, so after such and such time of use of your device it should reach certain level of power. If your battery was not charged full at the start then it will always show false percantage.
The solution is to fully charge the battery (possibly using the way described in some post above) and then reload the ROM once more.
Of cource when you buy a new battery, WM6 registers this (each battery has unic number) and creats new pattern for this battery. That is way it is so importatnt to properly charge the new battery when you load it first time.
Hope this is helpful.

I have 3 original batteries.
In principle, good battery can goes to perfect 0%.
First battery started half dead (that is phone is dead 30%) after upgrade from WM5 AKU1 to WM5 AKU2 happen to be around 6 months after I start using the phone, I thought it was the problem with WM5 AKU2 ROM. My usage pattern of this battery is that I charge anytime I wish with Power charger and also during sync. This battery is still with me now after 1 year I have encounter the problem. The dead % grow (no change of ROM) until now it is around 100%, that is phone is dead just before it goes to 99%.
Second battery was bought the same time my first battery has problem, 1 year passed. Usage pattern are, never use this battery for sync or short connections to PC USB, never charge my battery until it is 0% (always possible) or less than 5%, never upgrade ROM using this battery. Always charge to LED turns GREEN & always sync & upgrade ROM with the dead stuck at 100% battery. 1 year has gone, the second is still able to reach 0% till now with battery last average 1 to 3 days, normally 2 days & sometimes 4 days depends on usage pattern.
Third battery, claim by vendor that some electronics is modified compared to the those bought last year. Charged this battery, use a few time to check if it is an ok battery, need to do this as I have ever bought brand new dead battery last year. After confirmed it is a good battery, I continue using the second battery and third battery always carry along as backup in case I used up the second battery.
Hope my usage pattern can help some of you to have optimal use of the battery and do not let the manufacturer earn extra money due to the problem in the old version of the battery. Anyway, this original battery will be discontinued soon due to end of life of this product. Guess I will have to look forward of getting imitations when my second & third battery is gone or maybe when my phone is gone too.

Galaxy R battery issue

not dead black screen problem just battery issue usually in battery usage android os shows normally like this(image)
but sometimes it is 60 to 70 % and that battery drain too fast
is it a firmware issue ? or hardware ? my phone is 2 week old
this thing happen to me 2 time only
it happen to my phone at night on standby mode
and what all other aps( in the image) which is showing in battery usage it is all close(from task manager) but it shows it is using battery.
The battery usage being shown is the overall battery juice used by the apps listed since the phone is switched on.
Its basically shows the history of your battery usage and which app/system components have used how much % of your battery.
There's nothing wrong in that, its not a problem as you are assuming it to be and the apps shown there are not necessarily open.
ok thanks
i'll post in future if this problem come again
now android os usage is rising 40 + is it ok ?
Just enjoy the phone bro. Anyways u wont get more than 1~1.5 days ona a single charge except idealized conditions
I received my Galaxy this Thursday and didn't restart it at all until it drained itself yesterday in 14 hours.
After charing my phone to 100% and using it very very little during the day, it had drained itself completely after 14 hours. See the attached screen shots.
Android OS used 75% of my battery. It was completely useless.
Today after charging to 100% during the night it has been running fine. Currently at 68% after 9 hours with average use.
I've seen another thread about Android OS draining battery for SGS2, but I'm not sure there is a conclusion as to what processes causes it.
I suggest a restart if the battery starts draining too fast.
It's always like that with new smartphones. When I bought mine, battery time was just horrible - not even one day of ordinary usage. After few charging cycles (let's say after approx. 2 weeks) it got much much better. Now 2 days is not a problem at all.
Dont know how its works on custom roms/kernels but on stock 2.3.4 battery going down much faster with sd card on. If I put off sd card, battery life is extended. How no idea why.
lol i don't have any sd card yet but this problem occurs sometimes only
restarting works sometimes not every time i checked it
now what i found battery backup and drainage is ok in android phones wait for ICS 4.0.3(officially) lets see if they fix that battery bug. this thing should be solved in galaxy R.

Dude did you turn off Background auto sync ?
Your display usage is 2%, so it seems your phone was not used much by you. I feel you have turned on too many system background apps or something like that.
Do check that & update here if it solves the problem.

I had this problem on stock rom.
I googled around and it seems that Samsung OS has some bug where after switching the wifi off, it still keeps consuming CPU resources.
Try flashing a custom ROM.
I haven't had this problem since the day I shifted to InfectedROM+ardatdat's kernel.

[Q] help? Batterry precentage

Hi Guys, i'm noob, i wana ask about my htc sensation, after 2 year i'm using it, today i found
when battery charging (htc Senstaion) dismiss displaying percentage of battery after i restarting while charging.
****battery charging ------> Battery percentage displaying 60% then i restarting the phone while this situation
and then when phone finish restarting and ready to use battery precentage displaying 100%(full)
is it normal?
sorry my english bad
Boot into recovery and wipe battery stats.
Sent from my HTCSensation using XDA Premium 4 mobile app
if not all many users(including me) have this situation
it is a htc's common issue after rooting the device
there is no a solution yet
it is just a percentage misreading
by the way i don't know if wipe battery stats will help

Just a percentage misreading? But if the phone thinks it's at 100% won't it stop charging then?

probably it stops
i am not sure about that
edit: the point is the battery is increasing its percentage slower when it passes 60%-70%
but it charges the same
so if you reboot the device then it jumps at 90% or full charge

Is it known what causes this?
Someone above said "it is a htc's common issue after rooting". Is there any source on that? For all I know, percentage of charge of battery is determined by a combination of output voltage and amps, preferably referenced by a table taking battery age into account (correct me if I'm wrong though).
Rooting the device should not be an issue, unless HTC did something in their rom to detect this and let the battery percentage be wrong. Then again, most of us aren't on the stock rom. To be on another rom, the bootloader needs to be unlocked. Did HTC do something that unlocking the bootloader makes voltage/discharge readings unreliable? I doubt that...
I'm interested in this because I unlocked and flashed a Sensation XE for a friend of mine (SultanXDA's KitKat rom), but the battery discharges very, very fast, without an obvious cause. So I wonder whether it could be the battery is not fully charged and/or the phone decides it's empty to early.
"it is a htc's common issue after rooting"<- i said that
it was a source but i can't find it now
also i don't know if htc did something with unlocking the bootloader by purpose
if you flashed the rom recently don't judge the battery too early
give it 4-5 cyrcle charges until it settles down then see how it goes

I have exactly this problem.
It sounds like the same ROM, Saltan kit kat. I am using the latest kernal 3.4, having tried two kernals I get the same results. For example I charged the phone to full, and after 2 hours of use I'm down to 55%, WiFi on and browsing, gmail synced but not much else, screen brightness turned down etc.
I only flashed a couple days ago, will it improve massively over the next few days?
The phone was giving a days charge easily before flashing.
I am also noticing a message saying 'unfortunately process com.android.phone has stopped working' (or similar). When this happens and I click OK I notice the signal disappears for a few seconds before coming back. Could this be the cause of the problem?
Could it be he ROM?
I'm new to all this but managed to unlock, root, flash recovery, and flash the ROM thanks to the brilliant guides on XDA. Any help with the above would be appreciated.

i am facing the same problem , rather my problem is goes much further .
iam on stock ROM and not rooted my sensation. my device often restart automatically even when battery is about 90% or battery is 40% and it continue this from last 2-3 months.
and after restarting battery percentage is also changed, see attached pics.
i am tired of this rebooting , i observed that restaring is mostly when i connect to calls or text msgs.
can somebody pleeeeeeaase help me.

Does anyone have any ideas? Today the phone lasted around 12 hours but with minimal use which isn't really good enough. I thought rooting and flashing would improve battery life but so far I am disappointed. I may try another ROM tomorrow.

This really sounds like your battery, especially if it's not the original or equivalent. But, it could also be an app on the background, keeping your phone from "deep sleep". Bad cell coverage (very low signal) also drains your battery relatively quickly when you're on 3G. A good WiFi connection consumes less power than 3G with bad signal. Another possibility could be (but unlikely) is that your phone is intended for another region and thus having trouble communicating with the GSM network.
- Check your battery.
- Check what your battery is used for.
- Check your battery time with network set to GSM only.

Still you keep saying "after rooting" which is significantly different from unlocking the bootloader and flashing. Furthermore, to me it seems far more people report "better battery life" with their new roms.
About initially flashing the rom: i thought format of system, data and cache (including dalvik cache) ought to be enough. It has had somewhere between the 10 and 20 charge cycles by now. Battery life improved a little, but it's still far from acceptable. The battery percentage between reboots should only differ marginally between reboots (might need a few minutes of usage to become accurate). Also notable: over 20% difference in percentage reading between rom and recovery.
I wouldn't mind investigating this. So I wonder if anyone with "proper" battery life could provide me a "dumpsys" for the battery service and would perhaps have the time to take a look at /proc with me.

i unlocked the bootloader and root the device at the same period and i stayed for months with the stock rom
i don't know which one is responsible for percentage misreadings
also don't get confused
i am talking only for percentage misreadings and not for better battery life
and only when you charge the device.not unplugged
of course i had(and i still have) very good battery life with whatever rom i have flashed
by the way i have noticed the percentage difference between recovery and rom but i don't remember if it was 20%

Alright, thanks for clearing that up. I really want to solve this issue, so I'm quite keen on getting the facts straight.
Back to my issue then (yeah I'm effectively hijacking this thread): is it possible the percentage misreading is causing the battery not to fully charge and/or discharge? Or should I direct my search to another cause?
This is what I found (or did not find) so far:
- Stand-by time seems great, the drain occurs when the screen is on.
- There is nothing in the normal battery usage (usage goes to screen)
- I was unable to detect an obvious culprit with better battery stats.
- I did notice that when I do a dumpsys, service battery shows voltage in V, while my Sony shows it in mV.
- I tried offline charging for about an hour today (light still orange), after boot the battery indicator showed 100%. It dropped to 86% in 7 to 8 minutes.

probably never truly reached the full charge(100%) when charged it in that one hour
by the way how old is your battery?
did you try with a new one?

since you are completely stock then the only thing i can tell you is to check your battery if it fits correctly
also how old is it?

please see attached screenshots
what do u think , is this battery or some hardware etc fault??

Don't worry about battery life until 2 week after !!!!

Hi everyone , I'm new in the community but I already found that this is one of the best phone forums online , normally you come here for help because you have a problem right ? But today I'm just here to give an advice, I notice that many people complain about the battery life on their new phones , I had the same issue with my note 5 , I saw a video on YouTube and the phone showed an estimation of battery usage of 18hours while mine only showed 9 , I immediately thought that my phone was broken or something until a month later I realized that I was getting more than 20 hours of battery usage , when we use a phone for the first 3-5 days ( specially android) we can't expect it to be fully optimized because it's still learning your behavior and phone usage, just by installing a new app your making your phone to "learn to do something new" when I got my s7 edge I didn't expected to have great battery life , I was constantly installing and removing apps , flashing Roms and trying themes and etc. Now after a month later I use my phone on a pretty standard routine , I used package disabled but it only made my phone laggy and slower , so I decided to use my phone on the stock way , I running all stock , ( only disabled the apps that come with the phone that I don't use like power point , Samsung gear and health...) and after I did this I noticed a huge bump on battery life , I went from 12 hour of usage and 4:30-5hours of SOT to 30hours of usage and 8hours of SOT
After installing a custom/stock rom make sure to drain the battery completely just once to calibrate it !
I can never get more than 6 hrs sot.. Gonna follow your tips and write back in a week or so. Thanks for sharing!

Feel free to use package disabler, it was a lifesaver to me with my note 5 but not on the s7 , but other users report that has been really helpful other thing you could try even that the impact will be minimal is using a dark theme ,
Also don't update to the newer firmware if on Exynos. Seems to hit battery life by 25% or more as android system goes from around 5% to 15-20% battery usage.

with newer firmware you mean the may update?
with me it was the other thing around, in the beginning it was quite good but now, its worse. is it because of the bright sunlight or the phone getting hot because it was around 30 degrees almost?
you see...screen on time about 2 hours
most active battery drainer, android itself
Only way for me to get 4 hrs of sot i have to plug in to charge and disconnect before i get to 90 cause then it seems to thing its fully charged and battery meter resets (on battery).

The thing is, I have disabled half of the system already, but it just feels like it's doing even worse than before so I'm leaning back on running stock again.
Yes original firmware much better battery than the update

It didn't work either to me , this is what I think , it may sound stupid but it could be the true cause , I think when you use an app like package disabler to disable things on your phone and then you accidentally touch to open the app or setting disabled the phone will think "what's going on here" why is this disabled? And it maybe tries to access/ open the package again and again causing it to actually drain battery !, You could a cache wipe , it worked for me , I follow all guides to extend battery life using package disabler, custom rom , flashing zips to delete bloatware but none of them worked for me , instead I went all stock ,and after installing the stock rom I did a factory reset and them the cache wipe, it worked flawless to me , the phone now works like a charm , no overheating (maybe I don't feel it because I got a case ) but the point is try to find your own solution , every s7 edge it's unic, maybe a simple reebok on your phone could resolve all of your problems , and a very important thing !!!!! If you flash a rom /kernel make sure you let your battery drain completely just once to calibrate it!
I wiped nothing, stock rom latest APD1 , aod off now but on sometimes , location on, sync on 3 emails, disabled a few things with ez package disabler. Browsed the net for all the time the screen was on, WiFi on while screen of and on for atleast 2 hrs while using line messenger and used Spotify for around 30 to 40 mins. This is sot and battery usage.
I don't know how u manage to get such bad battery life, swear u guys r fu#*ING about with sh%t too much, let it settle.

Great battery life , you can easily achieve 3 days of battery life and 8-9 hours of SOT I guess which is great for you , just consider yourself in the 5% of people that own a phone with no battery issues , I'm happy with my 8hours of SOT and I could achieve 3days like you just by using WiFi, I use LTE because it's faster were I live but remember that there are people so disappointed with their phones because they want to get the most out of their phones and just can't, may I ask if you are amazed with your battery life or do you own other device that beats the s7 on battery ?
I am amazed, it's as good as, if not better than my previous phone the z3, which was running a custom rom and kernel.
I do consider myself lucky to have the phone run so well right out the box.
Also when I said alot r fu#&ng around with their device, I meant roughly the same as you, I didn't mean to imply their problems r not actually there. I meant as u had said, changing roms, removing apps for new, disabling apps, not letting anything settle, wont give good results in battery life.

Holy smoke, 5+ hrs sot in half of battery. I've been trying to get more than 6 hrs for like a month now with different roms and optimizations, not even close..
I hate to be the voice of cynicism, but we do need to stop this stuff somewhere. The original post is utter nonsense. The suggestion that phones 'learn' your behaviour just simply isn’t how kernels work. There's a very small degree of 'learning' but power management is a very reactive process based on exactly what's happening. The only thing new apps change is what processes are running, and the kernel will instantly scale to do what it 'thinks' is right. Some managers will observe processes for a bit longer and react based on that - but we're talking hours at most, NOT days.
The only credit I'd give to this idea (which seems to be all over XDA for some reason) is that the first few days people use their new shiny phone a lot more than usual, and probably also more than they’d think. They also become far more aware of battery life and will even turn on the screen just to check battery life, which will obviously accumulate batery drain - so the bit about using your phone more is certainly true. But anything about Android being some sort of AI Neural Network app learning extraveganza that learns what you do over several days is (for the most (significant) part) wrong.
Think this is just descending into another battery thread and we have one here already

[HELP] H60-L04 Battery drain (20h in stand-by mode)

Hi all,
I am facing some battery issues for a month now. It dropped suddenly from 3 days autonomy to 20 hours and can't finf the reason.
Tests I did
0) Identify apps consuming battery (google service and so on...). Did many changes but at the end same problem.
1) Update from B521 to B860 (OTA)
From now on, all tests are donr without any additionnal applications
2) Wipe cache + wipe data
3) Downgrade to B521 (first B800 then B521)
4) Test in stand-by mode. Still having the issue! This is wierd to me. Battery drains exactly the same with phone in stand-by mode or not!
5) Test with different SIM cards
6) Test forcing 3G/2G (no 4G). A bit better (about 1 day without using the phone)
8) Test without SIM nor google account connected... same issue
Any ideas?

Change to default theme and test again.

Thank you for your suggestion.
I'm currently running "Spectrum" theme. Which I guess is the default one as I haven't change anything since reinstall.
I'm facing battery problems since I'm running Marshmallow...
In battery settings it shows that the display is draining battery the most. There's no specific app shown.
If I get 2 and a half hours of screen on time I can be happy...
Sorry for not having an answer but I'm feeling with you.
Just installed "Better Battery Stats" and "Wakelocks detector lite" even if I am not rooted (followed tutorials for non rooted devices).
Hope I get more info tgis way.
I'll post results for experts analysis
Just uploaded better battery stats dump after first full discharge (see 1rst post)
If someone can have look, as I can't see anything strange...
I guess it is the update, it seems it's not fully optimized yet.

I downgrade to B521 and even B390. Same problem!
Do you think I have a hardware issue.
Battery tools says battery is "good".
Is anybody see something stange on BBS attached on 1st post?
Hello, I hope I can help with this information. i've been all day with airplane mode and just Wi-Fi on and with 3h 36m of screen on time. The second picture shows how the system is half of the time awake and the other half in deep sleep. I always need to charge this phone every night, because when I'm at home I'm almost always below 20% of the battery. I'm at the latest version B860, but I've have had this battery life since I bought this phone like three months ago.

Hello Vicioxis,
In my case I used to have at least 2 days without needed to charge the device. It changed suddenly to 20h max without change the way I use the phone.
Actuality, it doesn't seems to change anything wether I'm using the phone or not...
I added some thumbmails and a new BBS dump file in case somebody sees something wrong:crying:
As you can see, the device is mostly in deep sleep but I have a lot of wakelocks!
Has anyone here installed Kangvip ROM or the stock or any other? Also I feel the smartphone almost always warm at the back-right. Is this normal? Should I try to install any custom ROM to see if this improves?
